    Background Undernutrition remains highly prevalent in African children, highlighting the need for accurately assessing dietary intake. In order to do so, the assessment method must be validated in the target population. A triple pass 24 hour dietary recall with volumetric portion size estimation has been described but not previously validated in African children. This study aimed to establish the relative validity of 24-hour dietary recalls of daily food consumption in healthy African children living in Mbale and Soroti, eastern Uganda compared to simultaneous weighed food records. Methods Quantitative assessment of daily food consumption by weighed food records followed by two independent assessments using triple pass 24-hour dietary recall on the following day. In conjunction with household measures and standard food sizes, volumes of liquid, dry rice, or play dough were used to aid portion size estimation. Inter-assessor agreement, and agreement with weighed food records was conducted primarily by Bland-Altman analysis and secondly by intraclass correlation coefficients and quartile cross-classification. Results 19 healthy children aged 6 months to 12 years were included in the study. Bland-Altman analysis showed 24-hour recall only marginally under-estimated energy (mean difference of 149kJ or 2.8%; limits of agreement -1618 to 1321kJ), protein (2.9g or 9.4%; -12.6 to 6.7g), and iron (0.43mg or 8.3%; -3.1 to 2.3mg). Quartile cross-classification was correct in 79% of cases for energy intake, and 89% for both protein and iron. The intraclass correlation coefficient between the separate dietary recalls for energy was 0.801 (95% CI, 0.429-0.933), indicating acceptable inter-observer agreement. Conclusions Dietary assessment using 24-hour dietary recall with volumetric portion size estimation resulted in similar and acceptable estimates of dietary intake compared with weighed food records and thus is considered a valid method for daily dietary intake assessment of

    Cancer diagnosis and treatment may influence dietary intake. The validity of using self-reported methods to quantify dietary intake has not been evaluated in childhood cancer survivors. We validated total energy intake (EI) reported from Food Frequency Questionnaire (FFQ) and repeated 24-hour diet recalls (24HRs) against total energy expenditure (TEE) measured using the doubly labeled water method in 16 childhood cancer survivors. Dietary underreporting, assessed by (EI-TEE)/TEE × 100%, was 22% for FFQ and 1% for repeated 24HRs. FFQ significantly underestimates dietary intake and should not be used to assess the absolute intake of foods and nutrients in childhood cancer survivors.

    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

    Flavonols, flavanones and flavones (FLAV) are sub-classes of flavonoids that exert cardioprotective and anti-carcinogenic properties in vitro and in vivo. We aimed to estimate the FLAV dietary intake, their food sources and associated lifestyle factors in ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. FLAV intake and their food sources for 36 037 subjects, aged between 35 and 74 years, in twenty-seven study centres were obtained using standardised 24 h dietary recall software (EPIC-SOFT). An ad hoc food composition database on FLAV was compiled using data from US Department of Agriculture and Phenol-Explorer databases and was expanded using recipes, estimations and flavonoid retention factors in order to increase its correspondence with the 24 h dietary recall. Our results showed that the highest FLAV-consuming centre was the UK health-conscious group, with 130·9 and 97·0 mg/d for men and women, respectively. The lowest FLAV intakes were 36·8 mg/d in men from Umeå and 37·2 mg/d in women from Malmö (Sweden). The flavanone sub-class was the main contributor to the total FLAV intake ranging from 46·6 to 52·9 % depending on the region. Flavonols ranged from 38·5 to 47·3 % and flavones from 5·8 to 8·6 %. FLAV intake was higher in women, non-smokers, increased with level of education and physical activity. The major food sources were citrus fruits and citrus-based juices (especially for flavanones), tea, wine, other fruits and some vegetables. We concluded that the present study shows heterogeneity in intake of these three sub-classes of flavonoids across European regions and highlights differences by sex and other sociodemographic and lifestyle factors.

    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.

    To date, Web-based 24-hour recalls have not been validated using objective biomarkers. From 2006 to 2009, the validity of 6 Web-based DietDay 24-hour recalls was tested among 115 black and 118 white healthy adults from Los Angeles, California, by using the doubly labeled water method, and the results were compared with the results of the Diet History Questionnaire, a food frequency questionnaire developed by the National Cancer Institute. The authors performed repeated measurements in a subset of 53 subjects approximately 6 months later to estimate the stability of the doubly labeled water measurement. The attenuation factors for the DietDay recall were 0.30 for blacks and 0.26 for whites. For the Diet History Questionnaire, the attenuation factors were 0.15 and 0.17 for blacks and whites, respectively. Adjusted correlations between true energy intake and the recalls were 0.50 and 0.47 for blacks and whites, respectively, for the DietDay recall. For the Diet History Questionnaire, they were 0.34 and 0.36 for blacks and whites, respectively. The rate of underreporting of more than 30% of calories was lower with the recalls than with the questionnaire (25% and 41% vs. 34% and 52% for blacks and whites, respectively). These findings suggest that Web-based DietDay dietary recalls offer an inexpensive and widely accessible dietary assessment alternative, the validity of which is equally strong among black and white adults. The validity of the Web-administered recall was superior to that of the paper food frequency questionnaire.

    With technological innovation, comprehensive dietary intake data can be collected in a wide range of studies and settings. The Automated Self-Administered 24-h (ASA24) Dietary Assessment Tool is a web-based system that guides respondents through 24-h recalls. The purpose of this paper is to describe lessons learned from five studies that assessed the feasibility and validity of ASA24 for capturing recall data among several population subgroups in Canada. These studies were conducted within a childcare setting (preschool children with reporting by parents), in public schools (children in grades 5–8; aged 10–13 years), and with community-based samples drawn from existing cohorts of adults and older adults. Themes emerged across studies regarding receptivity to completing ASA24, user experiences with the interface, and practical considerations for different populations. Overall, we found high acceptance of ASA24 among these diverse samples. However, the ASA24 interface was not intuitive for some participants, particularly young children and older adults. As well, technological challenges were encountered. These observations underscore the importance of piloting protocols using online tools, as well as consideration of the potential need for tailored resources to support study participants. Lessons gleaned can inform the effective use of technology-enabled dietary assessment tools in research. PMID:28146125

    To be useful proxies of micronutrient intake at the population level in resource-limited societies, dietary diversity indicators should be simple and easy to collect in large surveys and their accuracy needs to be assessed. The present study aimed at comparing food group diversity indicators (FGI) derived from simple qualitative list-based questionnaires (qFGI) to the same indicators derived from quantitative 24-h recalls (QFGI). Both methods were administered separately on each of 3 recall days to women in 2 districts of Ouagadougou, Burkina Faso. Data were available for a total of 526 women x recalls. This study was performed within the framework of the Women's Dietary Diversity Project, which sought to analyze the relationships between various QFGI and the mean probability of adequacy (MPA) of women's diets across 11 micronutrients. The comparison between paired qFGI and QFGI scores was made both in terms of accuracy of the reporting by the list-based questionnaire, taking the QFGI as the gold standard, and in terms of performance of indicators in predicting an MPA > 60%. Examination of paired QFGI-qFGI differences revealed that the more disaggregated the FGI, the higher were the mean differences in scores. Food groups most frequently misreported often corresponded to foods put in small quantities in sauces. Overreporting by list-based questionnaires was observed for indicators applying a 15-g minimum quantity of consumption for a group to count in the score and this may result in weaker performance in predicting the MPA. These results highlight trade-offs between accuracy and simplicity when operationalizing FGI through qualitative questionnaires.

    Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunately impossible to achieve through the asynchronous exchange of classical and quantum messages. Perfect security can nonetheless be achieved if each party splits into two agents exchanging classical information at times and locations satisfying strict relativistic constraints. A relativistic multiround protocol to achieve this was previously proposed and used to implement a 2-millisecond commitment time. Much longer durations were initially thought to be insecure, but recent theoretical progress showed that this is not so. In this Letter, we report on the implementation of a 24-hour bit commitment solely based on timed high-speed optical communication and fast data processing, with all agents located within the city of Geneva. This duration is more than 6 orders of magnitude longer than before, and we argue that it could be extended to one year and allow much more flexibility on the locations of the agents. Our implementation offers a practical and viable solution for use in applications such as digital signatures, secure voting and honesty-preserving auctions.

    Full Text Available Collecting large-scale population data on dietary intake is challenging, particularly when resources and funding are constrained. Technology offers the potential to develop novel ways of collecting large amounts of dietary information while making it easier, more convenient, intuitive, and engaging for users. INTAKE24 is an online multiple pass 24 h dietary recall tool developed for use in national food and nutrition surveys. The development of INTAKE24 was a four-stage iterative process of user interaction and evaluation with the intended end users, 11–24 years old. A total of 80 11–24 years old took part in the evaluation, 20 at each stage. Several methods were used to elicit feedback from the users including, ‘think aloud’, ‘eye tracking’, semi-structured interviews, and a system usability scale. Each participant completed an interviewer led recall post system completion. Key system developments generated from the user feedback included a ‘flat’ interface, which uses only a single interface screen shared between all of the various activities (e.g., free text entry, looking up foods in the database, portion size estimation. Improvements to the text entry, search functionality, and navigation around the system were also influenced through feedback from users at each stage. The time to complete a recall using INTAKE24 almost halved from the initial prototype to the end system, while the agreement with an interviewer led recall improved. Further developments include testing the use of INTAKE24 with older adults and translation into other languages for international use. Our future aim is to validate the system with recovery biomarkers.

INTAKE24 is an online multiple pass 24-h recall tool developed for use with 11-24 year-old. The aim of the study was to undertake a comparison of INTAKE24 (the test method) with interviewer-led multiple pass 24-h recalls (the comparison method) in 180 people aged 11-24 years. Each participant completed both an INTAKE24 24-h recall and an interviewer-led 24-h recall on the same day on four occasions over a one-month period. The daily energy and nutrient intakes reported in INTAKE24 were compared to those reported in the interviewer-led recall. Mean intakes reported using INTAKE24 were similar to the intakes reported in the interviewer-led recall for energy and macronutrients. INTAKE24 was found to underestimate energy intake by 1% on average compared to the interviewer-led recall with the limits of agreement ranging from minus 49% to plus 93%. Mean intakes of all macronutrients and micronutrients (except non-milk extrinsic sugars) were within 4% of the interviewer-led recall. Dietary assessment that utilises technology may offer a viable alternative and be more engaging than paper based methods, particularly for children and young adults.

    Full Text Available   Background: Jaundice is one of the most frequent problems observed in newborns. Our purpose was to investigate the incidence and the risk factors on jaundice noted in the first 24 hours after birth.Methods: All newborns observed to have jaundice within the first 24 hours after birth were enrolled prospectively in this study. Laboratory evaluations included blood group typing of mother and newborn, hemoglobin and hematocrit, complete blood count, peripheral blood smear, reticulocyte count, G6PD activity, maternal indirect and neonatal direct Coombs test, and serum total, conjugated, and unconjugated bilirubin. In all cases, gender, birth weight, Apgar scores, gestational age, mode of delivery, birth trauma, cephalhematoma, maternal age, parity, or any siblings with neonatal jaundice were recorded. Data were analyzed using one-way ANOVA, Student's t-, and chi-square tests.Results: Of a total of 2096 newborns delivered in one year, 122 (5.8% developed jaundice within the first 24 hours after birth. Risk factors for hyperbilirubinemia were ABO incompatibility, prematurity, infection, G6PD deficiency, cephalhematoma, asphyxia, and Rh disease. There were no statistically significant relationships between jaundice and maternal age, parity, mode of delivery, neonatal gender or previous siblings with jaundice (p>0.05.Conclusions: Jaundice observed in the initial 24 hours after birth was infrequent, but clinically significant. All newborns should be followed by repeated exams within the first 24 hours after birth and before discharge, especially if the maternal blood group is O.

    Full Text Available Twenty-four-hour dietary recalls can provide high-quality dietary intake data, but are considered expensive, as they rely on trained professionals for both their administration and coding. The objective of this study was to develop an automated, self-administered web-based 24-h recall (R24W for a French-Canadian population. The development of R24W was inspired by the United States Department of Agriculture (USDA Automated Multiple-Pass Method. Questions about the context of meals/snacks were included. Toppings, sauces and spices frequently added to each food/dish were suggested systematically. A list of frequently forgotten food was also suggested. An interactive summary allows the respondent to track the progress of the questionnaire and to modify or remove food as needed. The R24W prototype was pre-tested for usability and functionality in a convenience sample of 29 subjects between the ages of 23 and 65 years, who had to complete one recall, as well as a satisfaction questionnaire. R24W includes a list of 2865 food items, distributed into 16 categories and 98 subcategories. A total of 687 recipes were created for mixed dishes, including 336 ethnic recipes. Pictures of food items illustrate up to eight servings per food item. The pre-test demonstrated that R24W is easy to complete and to understand. This new dietary assessment tool is a simple and inexpensive tool that will facilitate diet assessment of individuals in large-scale studies, but validation studies are needed prior to the utilization of the R24W.

    An application of artificial neural networks in short-term load forecasting is described. An algorithm using an unsupervised/supervised learning concept and historical relationship between the load and temperature for a given season, day type and hour of the day to forecast hourly electric load with a lead time of 24 hours is proposed. An additional approach using functional link net, temperature variables, average load and last one-hour load of previous day is introduced and compared with the ANN model with one hidden layer load forecast. In spite of limited available weather variables (maximum, minimum and average temperature for the day) quite acceptable results have been achieved. The 24-hour-ahead forecast errors (absolute average) ranged from 2.78% for Saturdays and 3.12% for working days to 3.54% for Sundays. (Author)

    In this preliminary prospective study, breast milk is sampled surrounding 4 religious fast days to determine the effect of a more than 24-hour fast on breast milk composition. The participants are 48 healthy women nursing healthy babies between 1 and 6 months of age. Samples are collected within 2 days before the fast (baseline), immediately after the fast, and 24 hours after fast completion. Samples are tested for sodium, calcium, phosphorus, triglycerides, total protein, and lactose. From baseline to immediately after fast, mean sodium, calcium, and protein levels increase (P = .013, P < .0001, and P < .0001, respectively) and mean phosphorus and lactose levels decrease (P < .0001 and P = .003, respectively). Mean triglycerides are unchanged. Twenty-four hours after fast, parameters are no longer significantly different from baseline except for elevated mean protein levels (P = .022) and lactose that is still reduced (P = .017). A fast of this nature is statistically associated with certain biochemical changes in breast milk.

    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.

    Full Text Available Objective: To compare the response on inmediate, 24 hour abdominal pain and referred shoulder pain (omalgia, when an intraperitoneal irrigation of bupivacaine was used as opposed to saline irrigation, in a group of patients who has laparoscopy done in a medical center in Cali, between April and June of 2000. Material and methods: After previous authorization and consentment by all 100 patients, a placebo was applied to 50 patients and bupivacaine to the other 50 patients, without randomization. The drug came in unmarked bottles, some of which had the medication and some had only saline and nobody knew beforehand which one was given to the patient. Its effect on post surgical pain was evaluated throught the cromatic visual analog scale, which subjectively determines the intensity of the pain according to colors which range from white to dark red, with a numerical equivalent from 0 to 10, in the following manner: zero (0 no pain , 2 mild, 4 moderate, 6 strong, 8 sevre and 10 intolerable pain. The scale was measured in the postoperative room two hours after procedure. A telephonic follow up was done at 24 hours after surgery, applying the visual analog scale on abdominal and shoulder pain. The information was processed using Epi Info 2000. An univariante and bivariante analysis was done. A comparasion was established using the differences in averages with inmediate abdominal pain and omalgia, and at 24 hours according to the use or not bupivacaine. Results: The variable are described in a univariante manner in relation to the distribution of pain at 2 and 24 hours, as well as the shoulder pain, where the mean score of pain decreases from 3.8, to 2.1 to 1.1 respectively.

    High dietary Na intake is associated with multiple health risks, making accurate assessment of population dietary Na intake critical. In the present study, reporting accuracy of dietary Na intake was evaluated by 24 h urinary Na excretion using the EPIC-Soft 24 h dietary recall (24-HDR). Participants from a subsample of the European Food Consumption Validation study (n 365; countries: Belgium, Norway and Czech Republic), aged 45-65 years, completed two 24 h urine collections and two 24-HDR. Reporting accuracy was calculated as the ratio of reported Na intake to that estimated from the urinary biomarker. A questionnaire on salt use was completed in order to assess the discretionary use of table and cooking salt. The reporting accuracy of dietary Na intake was assessed using two scenarios: (1) a salt adjustment procedure using data from the salt questionnaire; (2) without salt adjustment. Overall, reporting accuracy improved when data from the salt questionnaire were included. The mean reporting accuracy was 0·67 (95 % CI 0·62, 0·72), 0·73 (95 % CI 0·68, 0·79) and 0·79 (95 % CI 0·74, 0·85) for Belgium, Norway and Czech Republic, respectively. Reporting accuracy decreased with increasing BMI among male subjects in all the three countries. For women from Belgium and Norway, reporting accuracy was highest among those classified as obese (BMI ≥ 30 kg/m2: 0·73, 95 % CI 0·67, 0·81 and 0·81, 95 % CI 0·77, 0·86, respectively). The findings from the present study showed considerable underestimation of dietary Na intake assessed using two 24-HDR. The questionnaire-based salt adjustment procedure improved reporting accuracy by 7-13 %. Further development of both the questionnaire and EPIC-Soft databases (e.g. inclusion of a facet to describe salt content) is necessary to estimate population dietary Na intakes accurately.

    Full Text Available 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.

    2014-01-01

    This article contributes to literature on the sociology of sleep by exploring the sleeping practices and subjective sleep experiences of two social groups: shift workers and students. It draws on data, collected in the UK from 25 semi-structured interviews, to discuss the complex ways in which working patterns and social activities impact upon experiences and expectations of sleep in our wired awake world. The data show that, typically, sleep is valued and considered to be important for health, general wellbeing, appearance and physical and cognitive functioning. However, sleep time is often cut back on in favour of work demands and social activities. While shift workers described their efforts to fit in an adequate amount of sleep per 24-hour period, for students, the adoption of a flexible sleep routine was thought to be favourable for maintaining a work-social life balance. Collectively, respondents reported using a wide range of strategies, techniques, technologies and practices to encourage, overcome or delay sleep(iness) and boost, promote or enhance wakefulness/alertness at socially desirable times. The analysis demonstrates how social context impacts not only on how we come to think about sleep and understand it, but also how we manage or self-regulate our sleeping patterns.

    Full Text Available Abstract Background Information about behavior of energy intake in ultra-endurance cyclists during a 24-hour team relay race is scarce. The nutritional strategy during such an event is an important factor which athletes should plan carefully before the race. The purpose of this study was to examine and compare the nutritional intake of ultra-endurance cyclists during a 24-hour team relay race with the current nutritional guidelines for endurance events. Additionally, we analyzed the relationship among the nutritional and performance variables. Methods Using a observational design, nutritional intake of eight males (mean ± SD: 36.7 ± 4.7 years; 71.6 ± 4.9 kg; 174.6 ± 7.3 cm; BMI 23.5 ± 0.5 kg/m2 participating in a 24-hour team relay cycling race was assessed. All food and fluid intake by athletes were weighed and recorded. Additionally, distance and speed performed by each rider were also recorded. Furthermore, before to the race, all subjects carried out an incremental exercise test to determine two heart rate-VO2 regression equations which were used to estimate the energy expenditure. Results The mean ingestion of macronutrients during the event was 943 ± 245 g (13.1 ± 4.0 g/kg of carbohydrates, 174 ± 146 g (2.4 ± 1.9 g/kg of proteins and 107 ± 56 g (1.5 ± 0.7 g/kg of lipids, respectively. This amount of nutrients reported an average nutrient intake of 22.8 ± 8.9 MJ which were significantly lower compared with energy expenditure 42.9 ± 6.8 MJ (P = 0.012. Average fluid consumption corresponded to 10497 ± 2654 mL. Mean caffeine ingestion was 142 ± 76 mg. Additionally, there was no relationship between the main nutritional variables (i.e. energy intake, carbohydrates, proteins, fluids and caffeine ingestion and the main performance variables (i.e. distance and speed. Conclusions A 24-hour hours cycling competition in a team relay format elicited high energy demands which were not compensated by energy intake of the athletes despite

Caregivers completed one of three constructed FFQs to measure the child's dietary consumption in the last week: FFQ1 did not incorporate portion sizes; FFQ2 provided portion sizes; and FFQ3 incorporated pictures of median portion sizes. During the same week, each caregiver also completed three 24-hour dietary recalls. Results from the FFQ were compared with corresponding results from the 24-hour dietary recalls.Santa Catarina Pinula, peri-urban Guatemala City.Caregivers (n = 145 of 6-11 year-old children: 46 completed FFQ1, 49 completed FFQ2, and 50 completed FFQ3.The mean values for all nutrients obtained from the 24-hour dietary recall were lower than for those obtained from the FFQs, excluding folic acid in FFQ3, cholesterol and zinc in FFQ2, and cholesterol, folic acid, magnesium, potassium, sodium, and zinc in FFQ1. Energy-adjusted Pearson correlation coefficients ranged from 0.07 (protein to 0.54 (cholesterol for FFQ1 and from 0.05 to 0.74 for FFQ2 and FFQ3. Agreement by both methods (FFQ and 24-hour dietary recalls of classifying children into the same or adjacent quartiles of energy-adjusted nutrient consumption ranged from 62.0% for cholesterol to 95.9% for vitamin B12 across all three FFQs.Our FFQs had moderate to good relative validity in measuring energy and nutrient intakes for 6-11 year-old Guatemalan children. More evidence is needed to evaluate their reproducibility and applicability in similar populations.

    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

    Full Text Available Epilepsy is a frequent neurological disorder well-known by ancient times. 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.

    Technology-based dietary assessment offers solutions to many of the limitations of traditional dietary assessment methodologies including cost, participation rates and the accuracy of data collected. The 24-h dietary recall (24HDR) method is currently the most utilised method for the collection of dietary intake data at a national level. Recently there have been many developments using web-based platforms to collect food intake data using the principles of the 24HDR method. This review identifies web- and computer-based 24HDR tools that have been developed for both children and adult population groups, and examines common design features and the methods used to investigate the performance and validity of these tools. Overall, there is generally good to strong agreement between web-based 24HDR and respective reference measures for intakes of macro- and micronutrients.

    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.

    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.

    Full Text Available 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 ± 680kJ/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.

    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.

    Full Text Available Background: Preeclampsia is a serious complication of pregnancy, and it is vital to diagnosis the condition as early as possible. Proteinuria is an important symptom of preeclampsia, and repeated urine analysis to screen for the condition is part of the standard antenatal care. The purpose of this study was to determine the correlation between 4- and 24-hour urine total protein values to examine whether the 4-hour urine samples could be used for the diagnosis of proteinuria in hypertensive disorders of pregnancy. Methods: A cross-sectional study was performed on 110 pregnant (after gestational week 20 of pregnancy patients who were hypertensive (blood pressure ≥140/90 mmHg and had proteinuria as defined by positive urinary protein of at least 1+ in dipstick. Patients' urine samples were collected over 24 hours; the first 4 hours were collected separately from the next 20-hours. Patients, who did not collect the 24-hour urine, were excluded from the study. One hundred patients met the criteria, and were included in the study. The urine volume, total protein and creatinine levels of 4- and 24-hours samples were measured. The correlation between 4-hour and 24-hour samples was examined using Pearson correlation test. Results: Of the 100 patients, 42 had no proteinuria, 44 had mild proteinuria, and 14 had severe proteinuria. The urine protein values of 4-hour samples correlated with those of the 24-hours samples for patients with mild and severe forms of the disease (P<0.001, r=0.86. Conclusion: This study showed there was a correlation between 4-hour and 24-hour urine proteins. The finding indicates that a random 4-hour sample might be used for the initial assessment of proteinuria

    Whether there are differences between countries in the validity of self-reported diet in relation to BMI, as evaluated using recovery biomarkers, is not well understood. We aimed to evaluate BMI-related reporting errors on 24 h dietary recalls (24-HDR) and on dietary questionnaires (DQ) using biomarkers for protein and K intake and whether the BMI effect differs between six European countries. Between 1995 and 1999, 1086 men and women participating in the European Prospective Investigation into Cancer and Nutrition completed a single 24-HDR, a DQ and one 24 h urine collection. In regression analysis, controlling for age, sex, education and country, each unit (1 kg/m²) increase in BMI predicted an approximately 1·7 and 1·3 % increase in protein under-reporting on 24-HDR and DQ, respectively (both P 0·15). In women, but not in men, the DQ yielded higher mean intakes of protein that were closer to the biomarker-based measurements across BMI groups when compared with 24-HDR. Results for K were similar to those of protein, although BMI-related under-reporting of K was of a smaller magnitude, suggesting differential misreporting of foods. Under-reporting of protein and K appears to be predicted by BMI, but this effect may be driven by 'low-energy reporters'. The BMI effect on under-reporting seems to be the same across countries.

    The 24-hour home help services that provide day and night care services at home becomes a public health interest in Japan. The purpose of this study was to evaluate the system of 24-hour home help services in a community that has successfully developed it. Participants of this focus group interview were home helpers who were actually engaged in 24-hour home help services in A town of Akita Prefecture. The focus group session was tape-recorded and the tapes were transcribed. The transcripts were evaluated and summarized in order to identify major categories and number of descriptive statements in each category. The results were as follows. First, the home helpers considered that their system of 24-hour home help services could be technically transferred to other communities in Japan. Secondary, the political leadership and the democratic system of community participation were the essential elements for promoting the 24-hour home help services. Thirdly, the regular meetings for discussion about cases and opinion exchanges were required more extensively in the future.

    Objective The aim of this study was to investigate the clinical and laboratorial factors associated with serum sodium variation during continuous renal replacement therapy and to assess whether the perfect admixture formula could predict 24-hour sodium variation. Methods Thirty-six continuous renal replacement therapy sessions of 33 patients, in which the affluent prescription was unchanged during the first 24 hours, were retrieved from a prospective collected database and then analyzed. A mixed linear model was performed to investigate the factors associated with large serum sodium variations (≥ 8mEq/L), and a Bland-Altman plot was generated to assess the agreement between the predicted and observed variations. Results In continuous renal replacement therapy 24-hour sessions, SAPS 3 (p = 0.022) and baseline hypernatremia (p = 0.023) were statistically significant predictors of serum sodium variations ≥ 8mEq/L in univariate analysis, but only hypernatremia demonstrated an independent association (β = 0.429, p < 0.001). The perfect admixture formula for sodium prediction at 24 hours demonstrated poor agreement with the observed values. Conclusions Hypernatremia at the time of continuous renal replacement therapy initiation is an important factor associated with clinically significant serum sodium variation. The use of 4% citrate or acid citrate dextrose - formula A 2.2% as anticoagulants was not associated with higher serum sodium variations. A mathematical prediction for the serum sodium concentration after 24 hours was not feasible. PMID:27410407

    Some rhythm and conduction abnormalities can occur in children with acute rheumatic fever. These abnormalities have been defined based on standard electrocardiography; however, the real prevalence of these abnormalities has not been investigated previously by the evaluation of long-term electrocardiographic recordings. In this study, we evaluated the asymptomatic rhythm and conduction abnormalities in children with acute rheumatic fever by evaluating the 24-hour electrocardiography. We evaluated the standard electrocardiography and the 24-hour electrocardiography of 64 children with acute rheumatic fever. On standard electrocardiography, the frequency of the first-degree atrioventricular block was found to be 21.9%. Electrocardiography at 24 hours detected three additional and separate patients with a long PR interval. Mobitz type I block and atypical Wenckebach periodicity were determined in one patient (1.56%) on 24-hour electrocardiography. While accelerated junctional rhythm was detected in three patients on standard electrocardiography, it was present in nine patients according to 24-hour electrocardiography. Premature contractions were present in 1.7% of standard electrocardiography, but in 29.7% of 24-hour electrocardiography. Absence of carditis was found to be related to the presence of accelerated junctional rhythm (p > 0.05), and the presence of carditis was found to be related to the presence of premature contractions (p = 0.000). In conclusion, our results suggest that in children with acute rheumatic fever, the prevalence of rhythm and conduction abnormalities may be much higher than determined on standard electrocardiography. Further studies are needed to clarify whether or not these abnormalities are specific to acute rheumatic fever.

This finding raises the question of whether similarities exist between male recreational 24-hour ultramarathoners and male recreational marathoners.Methods: The association between age, anthropometric variables (ie, body mass, body height, body mass index, percent body fat, skeletal muscle mass, limb circumference, and skinfold thickness at the pectoral, mid axillary, triceps, subscapular, abdominal, suprailiac, front thigh, and medial calf sites, previous experience and training characteristics (ie, volume, speed, and personal best time, and race time for 79 male recreational 24-hour ultramarathoners and 126 male recreational marathoners was investigated using bivariate and multivariate analysis.Results: The 24-hour ultramarathoners were older (P < 0.05, had a lower circumference at both the upper arm (P < 0.05 and thigh (P < 0.01, and a lower skinfold thickness at the pectoral, axillary, and suprailiac sites (P < 0.05 compared with the marathoners. During training, the 24-hour ultramarathoners were running for more hours per week (P < 0.001 and completed more kilometers (P < 0.001, but were running slower (P < 0.01 compared with the marathoners. In the 24-hour ultramarathoners, neither anthropometric nor training variables were associated with kilometers completed in the race (P > 0.05. In the marathoners, percent body fat (P < 0.001 and running speed during training (P < 0.0001 were related to marathon race times.Conclusion: In summary, differences in anthropometric and training predictor variables do

    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 ..mu..Ci 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 lambda has, however, to be considered in each study. 94 refs. (EG).

    Objectives Diagnosis and clinical presentation of pediatric laryngopharyngeal reflux (LPR) is still controversial. The aims of this work were to study the possibility of performing 24-hour oropharyngeal pH monitoring for children in the outpatient clinic setup and to explore the results of this test in correlation to airway-related problems. Methods In this descriptive qualitative study, 26 children suffering from airway-related problems were included. Oropharyngeal 24-hour pH monitoring was performed for all subjects in the outpatient clinic setting. The distribution of airway diagnoses among the study group was studied versus the results of the pH monitoring. Results There were 16 males and 10 females participated in the study with a mean age of 6.88 (SD, ±5.77) years. Thirty-five percent of the patients were under the age of 3 years (range, 11 months to 3 years). Eight-five percent of the patients tolerated the pH probe insertion and completed 24-hour of pH recording. Laryngomalacia and subglottic stenosis (SGS) were more frequently reported in the positive LPR patients (77%). Conclusion Oropharyngeal 24-hour pH monitoring can be conducted for children in the outpatient setup even in young age children below 3 years old. Among the positive LPR group, SGS and laryngomalacia were the most commonly reported airway findings. PMID:27090271

    Background Hypertension is an important risk factor for cardiovascular outcomes. Primary health care (PHC) physicians should be prepared to act appropriately in the prevention of cardiovascular risk factors. However, the rates of patients with control of blood pressure (BP) remain low. The impact of the reclassification of high BP by 24-hour ambulatory BP monitoring (ABPM) can lead to different medical decisions in PHC. Objective To evaluate the agreement between the BP measured by a conventional method by PHC physicians and by 24-hour ABPM, considering different BP normal thresholds for the 24-hour ABPM according to the V Brazilian ABPM Guidelines and the European Society of Hypertension Guidelines. Methods A cross-sectional study including 569 hypertensive patients. The BP was initially measured by the PHC physicians and, later, by 24-hour ABPM. The BP measurements were obtained independently between the two methods. The therapeutic targets for the conventional BP followed the guidelines by the Eighth Joint National Committee (JNC 8), the V ABPM Brazilian Guidelines, and the 2013 European Hypertension Guidelines. Results There was an accuracy of 54.8% (95% confidence interval [95%CI] 0.51 - 0.58%) for the BP measured with the conventional method when compared with the 24-hour ABPM, with a sensitivity of 85% (95%CI 80.8 - 88.6%), specificity of 31.9% (95%CI 28.7 - 34.7%), and kappa value of 0.155, when considering the European Hypertension Guidelines. When using more stringent thresholds to characterize the BP as "normal" by ABPM, the accuracy was 45% (95%CI 0.41 - 0.47%) for conventional measurement when compared with 24-hour ABPM, with a sensitivity of 86.7% (95%CI 0.81 - 0.91%), specificity of 29% (95%CI 0.26 - 0.30%), and kappa value of 0.103. Conclusion The BP measurements obtained by PHC physicians showed low accuracy when compared with those obtained by 24-hour ABPM, regardless of the threshold set by the different guidelines.

A simple random-order crossover research design was used. Subjects (n = 9 males: age 21 ± 4 years, body mass 80.0 ± 9.0 kg, peak incremental 60-second cycling power output 297 ± 45 W [means ± SD] completed an identical exercise protocol conducted in hot ambient conditions (35oC, 50% relative humidity on two occasions; separated by 7-days. On each occasion, subjects received a different volume of 24-hour fluid intake (commercial beverage in random order. In each case, the fluid was taken in five equal aliquots over 24-hours. PV expansions 24-hours post-exercise were estimated from changes in haemoglobin and haematocrit. Dependent t-testing revealed no significant differences in PV expansions between trials, however a significant expansion with respect to zero was identified in the 3.0 L trial only. Specifically, PV expansions (% were; 1.5 L trial: (mean ± SE 2.3 ± 2.0 (not significant with respect to zero, 3.0 L trial: 5.0 ± 2.0 (p < 0.05, with respect to zero. Under the conditions imposed in the current study, ingesting the greater volume of the beverage lead to larger mean PV expansion

    The aim of this study was to compare the effects of static vs. dynamic stretching (DS) on explosive performances and repeated sprint ability (RSA) after a 24-hour delay. Sixteen young male soccer players performed 15 minutes of static stretching (SS), DS, or a no-stretch control condition (CC) 24 hours before performing explosive performances and RSA tests. This was a within-subject repeated measures study with SS, DS, and CC being counterbalanced. Stretching protocols included 2 sets of 7 minutes 30 seconds (2 repetitions of 30 seconds with a 15-second passive recovery) for 5 muscle groups (quadriceps, hamstring, calves, adductors, and hip flexors). Twenty-four hours later (without any kind of stretching in warm-up), the players were tested for the 30-m sprint test (with 10- and 20-m lap times), 5 jump test (5JT), and RSA test. Significant differences were observed between CC, SS, and DS with 5JT (F = 9.99, p effect size [ES] = 0.40), 10-m sprint time (F = 46.52, p stretching protocols in the total time (F = 1.55, p > 0.05), average time (F = 1.53, p > 0.05), and fastest time (F = 2.30, p > 0.05), except for the decline index (F = 3.54, p negative effect on explosive performances up to 24 hours poststretching with no major effects on the RSA. Conversely, the DS of the same muscle groups are highly recommended 24 hours before performing sprint and long-jump performances. In conclusion, the positive effects of DS on explosive performances seem to persist for 24 hours.

    Full Text Available The development of easy-to-use and accurate methods to assess the intake of energy, foods and nutrients in pre-school children is needed. KidMeal-Q is an online food frequency questionnaire developed for the LifeGene prospective cohort study in Sweden. The aims of this study were to compare: (i energy intake (EI obtained using KidMeal-Q to total energy expenditure (TEE measured via doubly labelled water and (ii the intake of certain foods measured using KidMeal-Q to intakes acquired by means of 24 h dietary recalls in 38 children aged 5.5 years. The mean EI calculated using KidMeal-Q was statistically different (p < 0.001 from TEE (4670 ± 1430 kJ/24 h and 6070 ± 690 kJ/24 h, respectively. Significant correlations were observed for vegetables, fruit juice and candy between KidMeal-Q and 24 h dietary recalls. Only sweetened beverage consumption was significantly different in mean intake (p < 0.001, as measured by KidMeal-Q and 24 h dietary recalls. In conclusion, KidMeal-Q had a relatively short answering time and comparative validity to other food frequency questionnaires. However, its accuracy needs to be improved before it can be used in studies in pre-school children.

    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 (Pcamera (MP24+SC) reduced the magnitude of under-reporting by 8% for men and 6% for women compared with the MP24 alone (Pcameras enhance the accuracy of self-report by providing passive and objective information regarding dietary intake. High-definition image sensors and increased imaging frequency may improve the accuracy further.

    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.

    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

    Full Text Available The effect of fasting prior to morning exercise on 24-hour energy intake was examined using a randomized, counterbalanced design. Participants (12 active, white males, 20.8±3.0 years old, VO2max:   59.1±5.7 mL/kg/min fasted (NoBK or received breakfast (BK and then ran for 60 minutes at 60%  VO2max. All food was weighed and measured for 24 hours. Measures of blood glucose and hunger were collected at 5 time points. Respiratory quotient (RQ was measured during exercise. Generalized linear mixed models and paired sample t-tests examined differences between the conditions. Total 24-hour (BK: 19172±4542 kJ versus NoBK: 15312±4513 kJ; p<0.001 and evening (BK: 12265±4278 kJ versus NoBK: 10833±4065; p=0.039 energy intake and RQ (BK: 0.90±0.03 versus NoBK: 0.86±0.03; p<0.001 were significantly higher in BK than NoBK. Blood glucose was significantly higher in BK than NoBK before exercise (5.2±0.7 versus 4.5±0.6 mmol/L; p=0.025. Hunger was significantly lower for BK than NoBK before exercise, after exercise, and before lunch. Blood glucose and hunger were not associated with energy intake. Fasting before morning exercise decreased 24-hour energy intake and increased fat oxidation during exercise. Completing exercise in the morning in the fasted state may have implications for weight management.

    People called night owls habitually have late bedtimes and late times of arising, sometimes suffering a heritable circadian disturbance called delayed sleep phase syndrome (DSPS). Those with DSPS, those with more severe progressively-late non-24-hour sleep-wake cycles, and those with bipolar disorder may share genetic tendencies for slowed or delayed circadian cycles. We searched for polymorphisms associated with DSPS in a case-control study of DSPS research participants and a separate study of Sleep Center patients undergoing polysomnography. In 45 participants, we resequenced portions of 15 circadian genes to identify unknown polymorphisms that might be associated with DSPS, non-24-hour rhythms, or bipolar comorbidities. We then genotyped single nucleotide polymorphisms (SNPs) in both larger samples, using Illumina Golden Gate assays. Associations of SNPs with the DSPS phenotype and with the morningness-eveningness parametric phenotype were computed for both samples, then combined for meta-analyses. Delayed sleep and "eveningness" were inversely associated with loci in circadian genes NFIL3 (rs2482705) and RORC (rs3828057). A group of haplotypes overlapping BHLHE40 was associated with non-24-hour sleep-wake cycles, and less robustly, with delayed sleep and bipolar disorder (e.g., rs34883305, rs34870629, rs74439275, and rs3750275 were associated with n=37, p=4.58E-09, Bonferroni p=2.95E-06). Bright light and melatonin can palliate circadian disorders, and genetics may clarify the underlying circadian photoperiodic mechanisms. After further replication and identification of the causal polymorphisms, these findings may point to future treatments for DSPS, non-24-hour rhythms, and possibly bipolar disorder or depression.

    In addition to mean blood pressure, blood pressure variability is hypothesized to have important prognostic value in evaluating cardiovascular risk. We aimed to assess the prognostic value of blood pressure variability within 24 hours. Using MEDLINE, EMBASE and Cochrane Library to April 2013, we conducted a systematic review of prospective studies of adults, with at least one year follow-up and any day, night or 24-hour blood pressure variability measure as a predictor of one or more of the following outcomes: all-cause mortality, cardiovascular mortality, all cardiovascular events, stroke and coronary heart disease. We examined how blood pressure variability is defined and how its prognostic use is reported. We analysed relative risks adjusted for covariates including the appropriate mean blood pressure and considered the potential for meta-analysis. Our analysis of methods included 24 studies and analysis of predictions included 16 studies. There were 36 different measures of blood pressure variability and 13 definitions of night- and day-time periods. Median follow-up was 5.5 years (interquartile range 4.2-7.0). Comparing measures of dispersion, coefficient of variation was less well researched than standard deviation. Night dipping based on percentage change was the most researched measure and the only measure for which data could be meaningfully pooled. Night dipping or lower night-time blood pressure was associated with lower risk of cardiovascular events. The interpretation and use in clinical practice of 24-hour blood pressure variability, as an important prognostic indicator of cardiovascular events, is hampered by insufficient evidence and divergent methodologies. We recommend greater standardisation of methods.

    24 hour infusion of iloprost was compared with placebo infusion in 19 patients with stable intermittent claudication using a double blind, balanced crossover design. Despite significant inhibition of platelet aggregation to ADP and collagen (p less than 0.001) and the typical cardiovascular and gastrointestinal side effects, there was no significant effect on treadmill exercise times at any time up to 6 weeks after infusion. The 95% confidence limits indicated that an improvement of more than 25% was unlikely to occur. No significant changes in B thromboglobulin, platelet aggregate ratio, bleeding time, whole blood viscosity and euglobulin clot lysis time were demonstrated.

    Psychophysiological peculiarities of influence of a 24-hour shift work on the efficiency of operators have been discussed. It was shown that servicemen operators develop significant fatigue as a result of 24 hrs duty services. The informative psychophysiological characteristics which can be reliable indicators of fatigue level are highlighted. Individual psychophysiological indicators of fatigue level, according to different mechanisms of its development, have been proposed. The hypothesis about the existence of several compensatory mechanisms for maintenance of long duty operators' working capacity has been formulated.

    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.

    It is still debated whether the deterioration of the sleep pattern, frequently reported by elderly subjects, is due only to aging per se. Other factors associated with aging or modifications of biological rhythms could also be involved. Elderly subjects frequently complain of daytime sleepiness, but it is not clear whether this actually represents a return to a polyphasic structure of sleep, or only a consequence of a disturbed night sleep. Ten healthy, independent and active elderly subjects (age > 72 years) were elevated by means of 24-hour ambulatory polysomnography. Findings of nocturnal sleep were compared with sleep of the same group in the 24-hour period and with sleep of young healthy controls. We observed a fragmentation of nocturnal sleep, but a fairly good representation of stages and a preservation of cyclicity. Except for three cases, with early or late times of sleep onset and wake-up, sleep disruption did not seem to be related to modification of circadian rhythms. Only three subjects presented undesired daytime naps, whereas the others either did not show daytime sleep at all, or were used to having their siesta after lunch since their young adulthood. In normal aging, daytime sleep does not constitute a social problem. Ambulatory polysomnography is a valid alternative to laboratory recordings in the identification of daytime sleep.

    Background: Dietary recall accuracy is related to retention interval (RI) (i.e., time between to-be-reported meals and the interview), and possibly to prompts. To the best of our knowledge, no study has evaluated their combined effect. Objective: The combined influence of RI and prompts on children’s recall accuracy was investigated in this study. Two RIs [short (prior-24-h recall obtained in afternoon) and long (previous-day recall obtained in morning)] were crossed with 4 prompts [forward (distant-to-recent), meal-name (breakfast, lunch, etc.), open (no instructions), and reverse (recent-to-distant)], creating 8 conditions. Methods: Fourth-grade children (n = 480; 50% girls) were randomly selected from consenting children at 10 schools in 4 districts in a southern state during 3 school years (2011–2012, 2012–2013, and 2013–2014). Each child was observed eating school-provided breakfast and lunch, and interviewed one time under 1 of the 8 conditions. Condition assignment was constrained so that each had 60 children (30 girls). Accuracy measures were food-item omission and intrusion rates, and energy correspondence rate and inflation ratio. For each measure, linear models determined effects of RI, prompt, gender, and interactions (2-way, 3-way); race/ethnicity, school year, and district were control variables. Results: RI (P values < 0.015) and prompt (P values < 0.005) were significant for all 4 accuracy measures. RI × prompt (P values < 0.001) was significant for 3 accuracy measures (not intrusion rate). Prompt × gender (P = 0.005) was significant for omission rate. RI × prompt × gender was significant for intrusion rate and inflation ratio (P values < 0.001). For the short vs. long RI across prompts and genders, accuracy was better by 33–50% for each accuracy measure. Conclusions: To obtain the most accurate recalls possible from children, studies should be designed to use a short rather than long RI. Prompts affect children’s recall accuracy

    The results of previous studies evaluating the effect of four liquid formulations of proton-pump inhibitors on 24-hour intragastric pH are described. Patients with a gastrostomy who were resident in a Veterans Affairs medical center or its affiliated nursing home were eligible for enrollment in one of four open-label studies in which each patient served as his own control. Patients underwent 24-hour intragastric pH studies before and after receiving seven consecutive days of one of the following liquid formulations of a proton-pump inhibitor administered once daily: omeprazole granules 20 mg in orange juice, lansoprazole granules 30 mg in orange juice, simplified omeprazole suspension 20 mg, and simplified lansoprazole suspension 30 mg. The suspensions were prepared with 10 mL of 8.4% sodium bicarbonate solution. Mean intragastric pH was measured, as was the time pH stayed above 3.0 and 4.0 during the 24-hour period. Six to 14 patients participated in each study. The mean posttreatment pH was 4.9+/-0.8, 4.7+/-0.6, 4.1+/-1.5, and 5.1+/-1.1 for omeprazole granules in orange juice, lansoprazole granules in orange juice, simplified omeprazole suspension, and simplified lansoprazole suspension, respectively. Both drugs in orange juice maintained pH above 4.0 longer than 14 hours and above 3.0 for close to 20 hours, which are the levels deemed optimal for healing erosive esophagitis and duodenal ulcers, respectively. Simplified lansoprazole suspension maintained pH above those thresholds for the optimal times, but simplified omeprazole suspension did not (20 and 15 hr above 3.0, 17 and 12 hr above 4.0 for lansoprazole and omeprazole, respectively). Further development of liquid formulations of proton-pump inhibitors may have important implications for the treatment of acid-related diseases in patients, including children, who are unable to swallow capsules.

    2012-05-01

    Full Text Available Background: In patients with arterial hypertension, increased blood pressure (BP variability contributes to end organ damage independently from mean levels of arterial BP. Increased BP variability has been linked to alterations in autonomic function including sympathetic overdrive. We hypothesized that catheter-based renal sympathetic denervation (RDN confers beneficial effects on BPV. Methods and Results: Eleven consecutive patients with therapy-refractory arterial hypertension (age 68.9±7.0 years; baseline systolic BP 189±23mmHg despite medication with 5.6±2.1 antihypertensive drugs underwent bilateral RDN. Twenty-four hour ambulatory blood pressure monitoring (ABPM was performed before RDN and six months thereafter. BPV was primarily assessed by means of standard deviation of 24-hour systolic arterial blood pressures (SDsys. Secondary measures of BPV were maximum systolic blood pressure (MAXsys and maximum difference between two consecutive readings of systolic BP (deltamaxsys over 24 hours. Six months after RDN, SDsys, MAXsys and deltamaxsys were significantly reduced from 16.9±4.6mmHg to 13.5±2.5mmHg (p=0.003, from 190±22mmHg to 172±20mmHg (p<0.001 and from 40±15mmHg to 28±7mmHg (p=0.006, respectively, without changes in concomitant antihypertensive therapy. Reductions of SDsys, MAXsys and deltamaxsys were observed in 10/11 (90.9%, 11/11 (100% and 9/11 (81.8% patients, respectively. Although we noted a significant reduction of systolic office blood pressure by 30.4±27.7mmHg (p=0.007, there was only a trend in reduction of average systolic BP assessed from ABPM (149±19mmHg to 142±18mmHg; p=0.086.Conclusions: In patients with therapy-refractory arterial hypertension, RDN leads to significant reductions of BP variability. Effects of RDN on BPV over 24 hours were more pronounced than on average levels of BP.

    To evaluate if chest physiotherapy is beneficial to premature infants with respiratory distress syndrome (RDS) during the first 24 hours of life, 20 infants were randomly assigned to two groups; 10 infants in Group I received routine chest physiotherapy and suction, and 10 infants in Group II received suction only. The birth weight, gestational age, postnatal age, Apgar scores, blood gases, acid-base status, and ventilatory requirements prior to study were comparable between the two groups. There were no significant differences between the groups in the amount of endotracheal secretions removed, the PO2/FIO2 ratio, blood gases, and pH during the study. The incidence of patent ductus arteriosus (PDA), bronchopulmonary dysplasia (BPD), Grade I and II intraventricular hemorrhage (IVH), and mortality was comparable. However, five of 10 Group I and zero of 10 Group II infants developed Grade III or IV IVH (P less than 0.05).

    Solar atmosphere is a unique laboratory for the study of turbulent flows under extreme conditions (e.g. very high Reynolds numbers). The turbulent nature of the flow may be approached by determining how magnetic flux elements are transported on the solar surface, and measuring the spatio-temporal scales on which these small magnetic structures are organized. The process involved is diffusion. Several works explored this topic, both by simulations and observations, and the results are often contradictory, ranging from fully-developed turbulent scenarios to normal-diffusive motions. We analyze 24-hour continuous Hinode SOT observations of a supergranular region (for the first time these long scales are explored), studying the evolution of the mutual distance between magnetic element pairs and its scaling laws, in order to investigate the diffusion process. We find a super-diffusive behavior, with a gamma index depending on the spatial scale selected.

    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

    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 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 policy

    Full Text Available CONTEXT: Short sleep duration is associated with adverse health outcomes, but the mechanisms involved are unknown. It has been postulated that short sleep duration may elevate cortisol levels, but studies have had conflicting results. It is unclear whether these differing findings may be due to methodological issues, such as assessment of sleep duration. Specifically, objective versus subjective methods of measuring habitual sleep duration may account for the conflicting results found in epidemiological studies. OBJECTIVE: Our goal was to determine whether habitual sleep duration, measured objectively (by actigraphy and subjectively (by self-report, was associated with 24-hour urine free cortisol (UFC, a measure of integrated cortisol secretion. Our secondary goal was to determine whether slow wave sleep (SWS, determined by polysomnography was associated with 24-hour UFC. DESIGN/SETTING: Cross sectional study of community dwelling older men. PATIENTS/PARTICIPANTS: 325 men (mean age = 76.6 years, SD = 5.5 from the Portland site of the MrOS Sleep Study, who underwent 24-hour urine collection, polysomnography, actigraphy and sleep questionnaire. PRIMARY OUTCOME: 24-hour UFC. RESULTS: In this study of community dwelling older men, self-reported sleep duration was inversely related to 24-hour UFC levels. Participants reporting 5 to 8 hours of habitual sleep. However, sleep duration determined by actigraphy was not associated with 24-hour UFC in either univariable or multivariable regression models. SWS was not associated with 24-hour UFC. CONCLUSION: Objectively measured (i.e., actigraphic sleep duration is not associated with 24-hour UFC in these community dwelling older men. This finding, together with prior studies, suggests that elevated levels of integrated cortisol secretion is not the mechanisms by which short sleep duration leads to adverse health outcomes.

    Full Text Available Abstract Background Improvement of traditional methods for dietary assessment is necessary, especially in rural areas where it is more difficult to succeed with self-reporting methods. This study presents and validates a method for improving accuracy when measuring food and nutrient intake of individuals in rural areas. It is called the “Food photography 24-h recall method” (FP 24-hR and is a modified 24-h recall with the addition of a digital food photography record and a photo atlas. Methods The study was carried out in a rural area in the tropical region of Bolivia; 45 women participated. Validation of the method was made by comparing it with a reference method, the Weighed Food Record (WFR. During the FP 24-hR, digital photographs were taken by the subjects of all food consumed during a day and a 24-h recall questionnaire was conducted by an interviewer. An estimate of the amount of food consumed was made using a photo atlas and the photographs taken by the subjects. For validation, comparison was made between the calculations, by both methods, of the levels of food, and nutrient, intake. Results The comparison was made in 10 food categories; most of which were somewhat underestimated from −2.3% (cassava to −6.8% (rice, except for beverages (+1.6% and leafy vegetables (+8.7%, which were overestimated. Spearman’s correlation coefficients were highly significant (r from 0.75 for eggs to 0.98 for potato and cassava. Nutrient intakes calculated with data from both methods showed small differences from -0.90% (vitamin C to -5.98% (fat. Although all nutrients were somewhat underestimated, Pearson′s coefficients are high (>0.93 for all and statistically significant. Bland Altman analysis showed that differences between both methods were random and did not exhibit any systematic bias over levels of food and nutrient intake, with acceptable 95% limits of agreement. Conclusion The FP 24-hR exhibits acceptable differences when compared with

    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

    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

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.

    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.

    This study examined the feasibility of using indices obtained from a long term Holter ECG record for sudden cardiac arrest (SCA) risk stratification. The ndices tested were the QT-RR interval co-variability and the alternans ratio percentile (ARP(θ)) which is defined as the θ(th) percentile of alternans ratios over a 24 hour period. The QT-RR interval co-variabilities are evaluated by the serial correlation coefficient between QT and RR trend sequences (QTRC). Previously reported Kalman filter technique and a simple smoothing spline method for the trend estimation are compared. Parameter θ in the alternans ratio percentile index was optimized to achieve the best classification accuracy. These indices were estimated from 26 cardiovascular outpatients for Holter ECG record. Patients were classified into high and low risk groups according to their clinical diagnosis, and the obtained indices were compared with those of 25 control subjects. A risk stratification using the two indices QTRC and ARP(θ) yielded an average sensitivity of 0.812 and a specificity of 0.925. The sensitivities and specificities of all three categories exceeded 0.8 except for the sensitivity to detect the high-risk patient group. Other short-term ECG parameters may need to be incorporated in order to improve the sensitivity.

    Full Text Available INTRODUCTION: The normal blood glucose in rats is 100 mg glucose / 100 ml of blood plasma. After a 24hhour fast, a decrease around 30% of this value occurs. This reduction can reach 45% in a prolonged fast. Several processes controlled by neurohormonal mechanisms prevent a more pronounced decrease in blood glucose of animals subjected to fast. These processes are hepatic glycogenolysis, hepatic gluconeogenesis, decrease of glucose utilization and increase of fatty acids use by muscle tissue, and ketone bodies utilization by the central nervous system. OBJECTIVES: This study presents a learning object, mediated by computer, which simulates the determination of blood glucose (glycemia obtained from fed rats and from 24-hour fasted rats. MATERIALS AND METHODS: At first, cartoons were planned in order to show the biochemical and methodology fundamentals. The most representative images were selected, edited and inserted into an animation developed with the aid of the Adobe ® Flash 8 software. DISCUSSION AND RESULTS: The animated simulation of a standard glucose curve, followed by virtual evaluation of glucose in blood plasma samples were developed, associated with some questions. This object has been used by students of Biochemistry I (Pharmacy-UFRGS since second semester of 2009. The navigation features, design and interactivity have been evaluated as excellent by about 80% of them. CONCLUSION: Therefore, this learning object can be considered an adequate teaching resource as well as an innovative support in the construction of theoretical and practical knowledge of Biochemistry.

The aim of this study was to assess the impact of FC on maternal confidence and breast-feeding. Maternal confidence and rate of breast-feeding were assessed in 31 mothers offered FC that included special family rooms in the NICU, and in 30 mothers from a comparable NICU providing traditional care without such facilities. One week prior to hospital discharge, mothers in the FC group felt better informed regarding nursing issues and had more confidence in interpretation of the infants regarding feeding issues and in caregiving without staff attendance (P skill level for interpretation of the infant's signals and knowledge about breast-feeding (P < .05). Despite similar rate of breast-feeding at discharge, more infants in the FC group were breastfed 3 months after discharge (P < .05). An FC program in the NICU promoted better maternal confidence during the hospital stay and 3 months after discharge compared with traditional care.

    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.

    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 (pmicronutrients. The test 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

    In previous studies, of which several were underpowered, the relation between cardiovascular outcome and blood pressure (BP) variability was inconsistent. We followed health outcomes in 8938 subjects (mean age: 53.0 years; 46.8% women) randomly recruited from 11 populations. At baseline, we...... assessed BP variability from the SD and average real variability in 24-hour ambulatory BP recordings.

    The determination of the two urinary catecholamine metabolites homovanillic acid (HVA) and vanillylmandelic acid (VMA) is of crucial importance for the diagnosis and follow-up of neuroblastoma (NB). The standard practice for their measurement requires the use of 24-hour collections that are time consuming and difficult to obtain. In this article, we directly demonstrate that 24-hour collections and single spot urines are interchangeable for the determination of HVA and VMA expressed as ratio on creatinine concentration. This study can be useful for a faster management of NB at onset.

    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.

    Epidemiological studies of dietary habits in infancy and childhood face a number of difficulties, which are more or less specific for these ages. In connection with studies on dietary habits of Swedish infants and children an evaluation of different dietary assessment techniques was performed. Breastfeeding data obtained in retrospective interviews at six months had good validity. The reliability of breastfeeding and weaning data decreased over time. Short questions on food frequencies, often used in research and clinical practice, were shown to be a poor screening instrument and suffered from biases when used in groups of four- and eight-year-old children. Group mean estimations of dietary intake of four- and eight-year-old children obtained by 24-hour recalls were close to those of seven-day records from the same individuals. Dietary intake in a 13-year-old group according to 24-hour recall and dietary history differed significantly; the dietary history gave much higher estimations. The reliability of dietary history in a small group of 13-year-old boarding school children was fairly good. The internal validity of food recording was examined by use of chemical analysis of duplicate portions. Generally, there was good agreement between the records and the analysed duplicates. The intake of a number of nutrients varied during the week, often showing a maximum towards the weekend. The intake of vitamin C was higher in winter time, otherwise no seasonal variation was found. The intra-individual variation in dietary intake is illustrated and its consequences for dietary studies are discussed.

    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.

    Full Text Available INTRODUCTION: C-peptide and insulin measurements in blood provide useful information regarding endogenous insulin secretion. Conflicting evidence on sample stability and handling procedures continue to limit the widespread clinical use of these tests. We assessed the factors that altered the stability of insulin and C-peptide in blood. METHODS: We investigated the impact of preservative type, time to centrifugation, storage conditions and duration of storage on the stability of C-peptide and insulin on three different analytical platforms. RESULTS: C-peptide was stable for at least 24 hours at room temperature in both centrifuged and whole blood collected in K(+-EDTA and serum gel tubes, with the exception of whole blood serum gel, which decreased to 78% of baseline at 24 hours, (p = 0.008. Insulin was stable at room temperature for 24 hours in both centrifuged and whole blood collected in K(+-EDTA tubes. In contrast insulin levels decreased in serum gel tubes both centrifuged and whole blood (66% of baseline, p = 0.01 and 76% of baseline p = 0.01, by 24 hours respectively. C-peptide and insulin remained stable after 6 freeze-thaw cycles. CONCLUSIONS: The stability of C-peptide and insulin in whole blood K(+-EDTA tubes negates the need to conform to strict sample handling procedures for these assays, greatly increasing their clinical utility.

    Full Text Available Despite successful approaches to preserve organs, tissues, and isolated cells, the maintenance of stem cell viability and function in body fluids during storage for cell distribution and transportation remains unexplored. The aim of this study was to characterize urine-derived stem cells (USCs after optimal preservation of urine specimens for up to 24 hours. A total of 415 urine specimens were collected from 12 healthy men (age range 20-54 years old. About 6 × 10(4 cells shed off from the urinary tract system in 24 hours. At least 100 USC clones were obtained from the stored urine specimens after 24 hours and maintained similar biological features to fresh USCs. The stored USCs had a "rice grain" shape in primary culture, and expressed mesenchymal stem cell surface markers, high telomerase activity, and normal karyotypes. Importantly, the preserved cells retained bipotent differentiation capacity. Differentiated USCs expressed myogenic specific proteins and contractile function when exposed to myogenic differentiation medium, and they expressed urothelial cell-specific markers and barrier function when exposed to urothelial differentiation medium. These data demonstrated that up to 75% of fresh USCs can be safely persevered in urine for 24 hours and that these cells stored in urine retain their original stem cell properties, indicating that preserved USCs could be available for potential use in cell-based therapy or clinical diagnosis.

    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.

    Background As intraocular pressure (lOP) and lOP fluctuation are known risk factors for glaucoma,it is important to understand the effects of high myopia on these ocular parameters.The aim of this study was to investigate if primary open-angle glaucoma (POAG) patients with high myopia exhibit higher lOP and greater lOP fluctuations at resting conditions over 24 hours.@@Methods We designed a prospective control clinical study.Eighty-two eyes of 82 high-tension Chinese POAG patients only on prostaglandin analogue locally were divided into 3 groups according to various myopic grades (<-6.0 D,n=27 and between -0.76 and -5.99 D,n=33) or without myopia (-0.75 to 0.75 D,n=22).Single time lOP at 10 am,mean corrected 24-hour lOP,mean corrected night lOP,24-hour lOP fluctuation and lOPs of 10 am,2 pm,6 pm,10 pm,2 am,6 am and 8 am were measured.@@Results The lOP was higher in POAG patients with high myopia over those POAG alone in three ways:the elevated lOP value was 0.65 mmHg measured in single time lOP at 10 am,0.84 mmHg in mean corrected 24-hour lOP,0.97 mmHg in mean corrected night lOP.The 24-hour lOP fluctuation was lower in the two myopia groups than in non-myopia group.Further,using repeated measurement analysis of variance,there was no statistical significance among groups regarding the lOPs at the seven time points (P=0.77) and there was no interaction between groups and time points (P=0.71),but the difference of lOPs at the seven time points in same group was statistically significant (P=0.01).@@Conclusion High-tension POAG patients with high myopia,even on pharmacological glaucoma therapy,still have higher lOp,but 24-hour lOP fluctuation at resting conditions was lower in these patients.

    Twenty-four hour whole body indirect calorimetry has been used to study the effects of feeding, during a sedentary test day, isoenergetic diets which varied in fat (3 or 40 per cent of total energy) and carbohydrate (82 or 45 per cent) content. Three groups of women were studied: lean, obese and 'post-obese' after slimming. Energy expenditure was greater in absolute terms in the obese women. Twenty-four hour energy expenditure was lower by only 3-7 per cent when fasting compared to that when fed to achieve energy balance. There were no large differences in energy expenditure between the two diets or between the groups but the thermogenic effect of the high carbohydrate diet was significantly greater than that of the high fat diet (5.8 vs 3.5 per cent of energy expenditure: P less than 0.01). The post-obese tended to have lower energy expenditure per kg FFM than controls when fasting and when high-fat fed, but this pattern was not shown by the obese. Sleeping energy expenditure was particularly low in the post-obese group when high-fat fed. Dirunal variations in RQ appear to show more marked rise in morning RQ from the nocturnal minimum in the obese and post-obese, which might be evidence for an energy-saving mechanism through greater availability of stored dietary carbohydrate.

    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.

    The association of target organ damage with 24-hour systolic and diastolic blood pressure levels and ambulatory hypertension subtypes has not yet been examined in untreated Chinese patients. We measured left ventricular mass index by echocardiography (n=619), the urinary albumin:creatinine ratio (n=1047), and aortic pulse wave velocity by tonometry (n=1013) in 1047 untreated subjects (mean age, 50.6 years; 48.9% women). Normotension was a 24-hour systolic/diastolic blood pressure Hypertension subtypes were isolated diastolic hypertension and mixed systolic plus diastolic hypertension. We assessed associations of interest by multivariable-adjusted linear models. Using normotension as reference, mixed hypertension was associated with higher (P≤0.003) left ventricular mass index (+4.31 g/m(2)), urinary albumin:creatinine ratio (+1.63 mg/mmol), and pulse wave velocity (+0.76 m/s); and isolated diastolic hypertension was associated with similar left ventricular mass index and pulse wave velocity (P≥0.39), but higher urinary albumin:creatinine ratio (+1.24 mg/mmol; P=0.002). In younger participants (hypertension are major determinants of target organ damage irrespective of age and target organ, whereas 24-hour diastolic blood pressure and isolated diastolic hypertension only relate to the urinary albumin:creatinine ratio below middle age.

    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.

    The combination of benazepril plus amlodipine was shown to be more effective than benazepril plus hydrochlorothiazide in reducing cardiovascular events in the Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial. There was a small difference in clinic systolic blood pressure between the treatment arms favoring benazepril plus amlodipine. Ambulatory blood pressure monitoring provides a more rigorous estimate of blood pressure effects. A subset of 573 subjects underwent ambulatory blood pressure monitoring during year 2. Readings were obtained every 20 minutes during a 24-hour period. Between-treatment differences (benazepril plus amlodipine versus benazepril plus hydrochlorothiazide) in mean values were analyzed using ANOVA. Treatment comparisons with respect to categorical variables were made using Pearson's χ². At year 2, the treatment groups did not differ significantly in 24-hour mean daytime or nighttime blood pressures (values of 123.9, 125.9, and 118.1 mm Hg for benazepril plus amlodipine group versus 122.3, 124.1, and 116.9 for the benazepril plus hydrochlorothiazide group), with mean between-group differences of 1.6, 1.8, and 1.2 mm Hg, respectively. Blood pressure control rates (24-hour mean systolic blood pressure amlodipine rather than hydrochlorothiazide shown in the ACCOMPLISH trial was not caused by differences in blood pressure, but instead intrinsic properties (metabolic or hemodynamic) of the combination therapies.

    Full Text Available ABSTRACT Objective To identify dietary patterns in children up to thirty months of age and verify whether they are associated with parental dietary patterns, and socioeconomic and demographic characteristics. Methods This is a cross-sectional study with baseline data from a population-based study composed of 1,085 households from a representative sample of a metropolitan region in Rio de Janeiro, Brazil. The children's food intake was evaluated by two 24-hour recalls, and the dietary patterns were identified by principal component analysis stratified into two groups according to the children's age: 6 to 17 months; and 18 to 30 months. The explanatory variables collected by a structured questionnaire were socioeconomic and demographic characteristics, age at introduction of complementary foods, and parental dietary pattern. A Food Frequency Questionnaire was administered to assess parental dietary pattern, which was determined by principal component analysis. Multivariate linear regression estimated the effect of each explanatory variable on the children's dietary patterns. Results Three dietary patterns were identified in children aged 6-17 months (basic-mixed; mixed-plus; and milk-flours and two dietary patterns were identified in children aged 18-30 months: basic-mixed and mixed-plus. Multivariate linear regression showed that complementary feeding (b=0.108; p=0.004 was positively associated with the basic-mixed dietary pattern, and family income (b=0.002; p£0.01, with the mixed-plus dietary pattern. A negative association was found between the traditional parental dietary pattern and children's mixed-plus pattern in children aged 6-17 months (b=0.152; p=0.006 and in children aged 18-30 months (b=0.152; p=0.016. In children aged up to 18 months, parental education level (b=0.368; p£0.01 was positively associated with the mixed-plus dietary pattern. Conclusion Family income, parental education level, and parental dietary patterns are

    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.

    Full Text Available Background/Aim. Left ventricular hypertrophy (LVH, apart from arterial hypertension, is a risk factor for electrophysiologic heart condition disorder and sudden cardiac death. The aim of this study was to examine a relationship between complex ventricular arrhythmias and parameters of 24-hour ambulatory blood pressure monitoring in the patients with arterial hypertension and left ventricular hypertrophy (LVH, as well as their prognostic significance during a five-year follow-up. Methods. Ninety patients with arterial hypertension and LVH were included in this study (mean age 55.2±8.3 years. There were 35 healthy people in the control group (mean age 54.5±7.1 years. Left ventricular mass index was 171.9±32.4 g/m2 in the LVH group and 102.4±13.3 g/m2 in the control group. Clinical examination, echocardiogram, 24-hour ambulatory blood pressure monitoring and 24-hour holter monitoring were done in all of the examined persons. Ventricular arrhythmias were classified by the Lown classification. Results. In the LVH group there were 54 (60.0% of the patients with ≥ III Lown class. The best predictor of a Lown class were left ventricular mass index by using multivariate stepwise regression analyses (β = 0.212; p < 0.05 and small decrease of diastolic blood pressure during the night (β = -0.293; p < 0.01. The main predictor of bad prognosis was left ventricular mass index during a five year follow-up (β = 0.302; p < 0.01, for stepwise regression model: F = 8.828; p < 0.01, adjusted R2 = 0.091. Conclusion. Left ventricular arrhythmias are frequent in patients with lower decrease of blood pressure during the night. There was no correlation between the degree of ventricular arrhythmias and parameters from 24-hour blood pressure monitoring and a five-year prognosis in the patients with arterial hypertension and LVH. A bad five-year follow-up outcome of hypertensive disease depends on left ventricular mass index.

    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.

    In a series of double-blind randomised studies in normal volunteers with continuous intragastric pH monitoring, the effects of different dosage regimens of roxatidine acetate, a new H2-receptor antagonist, were compared with placebo and ranitidine. Roxatidine acetate 75 mg twice daily decreased median 24-hour gastric acidity from pH 1.6 to 3.2 and median nocturnal acidity from 1.5 to 3.0. Roxatidine acetate 150 mg at bedtime raised median 24-hour pH in the same 17 subjects to 2.4 and nocturnal pH to 5.9. In the second experiment, in 14 volunteers, roxatidine acetate 150 mg at bedtime was as effective as ranitidine 300 mg at night, raising median nocturnal pH from 1.4 to 6.65 compared to 6.7 for ranitidine. However, when drugs were taken after the evening meal (post cenam nocte; PCN) roxatidine acetate 150 mg was less potent than ranitidine 300 mg, with median night-time pH rising from 1.3 to 3.2 and 4.0, respectively, in 28 volunteers. Roxatidine acetate 300 mg PCN produced the greatest rise of pH, to 4.9, suggesting that the true potency ratio of the 2 drugs is between 1 and 2.

    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

    Full Text Available Ozone is a known oxidant present in the atmosphere and is commercially produced by simple ozonizer machines. It is a powerful antimicrobial agent in its gaseous and aqueous forms. Ozone readily dissolves in water and retains its antimicrobial property even in the dissolved state. In this study, the effect of 0.1 ppm ozonated water was analyzed on 24-hour supragingival plaque (SP samples in situ. SP was collected from the two most posterior teeth in the contra-lateral quadrants before and after a 30-second rinse with either distilled water (control group or 0.1 ppm ozonated water (test group. The plaque was used to count the number of total bacteria, total anaerobic bacteria, Streptococcus mutans, and Candida albicans on selective agar media. The statistical analysis of the number of colony forming units (CFUs obtained demonstrated a significant antimicrobial effect of ozonated water on the total bacteria (p = 0.01 and anaerobes (p = 0.02. A reduction in the post-rinse CFU count for Streptococcus mutans was also observed, but the effect was not statistically significant (p = 0.07. The Candida species was only grown from one sample. Ozonated water at the 0.1 ppm concentration was effective in reducing the load of 24-hour plaque bacteria, but it did not eliminate them completely.

    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 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.

    Twenty-four-hour energy expenditure (EE) and nonprotein respiratory quotient (RQnp) were measured by indirect calorimetry in 19 upper-body-obese (UBO) and 15 lower-body-obese (LBO) women with similar body mass index (BMI) and body fat percent. The measurements were performed in a respiration chamber on a predetermined physical activity program and a controlled diet. No differences between the UBO and LBO groups were found in 24-hour, daytime, and sleeping EE after adjustment for differences in fat-free mass (FFM). Furthermore, no group effect was observed in RQnp, but a positive correlation was found between RQnp and age. Despite the fact that an increased free fatty acid (FFA) turnover has been found in UBO subjects, the present study does not support the contention that upper-body obesity is accompanied by an increased lipid oxidation.

    The gastric antisecretory activity of roxatidine acetate was studied on 24-hour intragastric pH in 12 healthy male volunteers. The study was randomised, double-blind and double-dummy where either roxatidine acetate 150 mg as a slow release granulated formulation or placebo were administered at 7.30 pm or 10 pm. Roxatidine acetate 150 mg produced a significant decrease in the number of hours during which gastric acidity ranged between pH 1.5 and 4.0 which was consistent with the pharmacokinetic profile of the drug. There was no significant difference between the median intragastric pH values for early evening and bedtime administration of roxatidine acetate. The present data confirm that roxatidine acetate 150 mg inhibits gastric acid secretion but while a single evening dose is effective in controlling intragastric pH the results suggest there is no clear advantage in an early evening dose compared with a bedtime dose.

    Renal failure is a common morbidity in multiple myeloma (MM). Although proteinuria has been increasingly reported in malignancies, it is not routinely used to refine risk estimates of survival outcomes in patients with MM. Here we aimed to investigate initial serum albumin and 24-hour daily protein excretion (24-h DPE) before treatment as prognostic factors in patients with MM. We conducted a retrospective analysis of 102 patients with myeloma who were ineligible for haematopoietic stem cell transplantation between October 2000 and December 2012. Initial proteinuria was assessed before treatment by quantitative analysis of 24-hour urine samples. The demographic and laboratory characteristics, survival outcome, and significance of pre-treatment 24-h DPE and albumin in the new staging system of MM were analyzed. Pre-treatment proteinuria (>300 mg/day) was present in 66 patients (64.7%). The optimal cut-off value of 24-h DPE before treatment was 500 mg/day. Analysis of the time-dependent area under the curve showed that the serum albumin and 24-h DPE before treatment were better than 24-h creatinine clearance rate and β2-microglobulin. A subgroup analysis showed that an initial excess proteinuria (24-h DPE ≥ 500 mg) was associated with poor survival status (17.51 vs. 34.24 months, p = 0.002). Furthermore, initial serum albumin was an independent risk factor on multivariate analysis (albumin and 24-h DPE before treatment showed significant prognostic factors in patients with MM, and the new A-DPE staging system may be utilized instead of the International Staging System. Its efficacy should be evaluated by further large prospective studies.

    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 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.

    Malnutrition is endemic in developing countries, which also bear the brunt of the human immunodeficiency virus (HIV) pandemic. HIV and its complications have a significant impact on nutritional status. Malnutrition and HIV have deleterious interactions. Dietary inadequacy is a major cause of malnutrition and few studies have been done to assess dietary adequacy in HIV-infected individuals and the factors affecting intake. Dietary intake of 71 consecutive patients was determined using 24-hour dietary recall, with the help of a questionnaire and a structured interview, and then compared with the recommended dietary allowances (RDA). The dietary intake of energy, total fat, fibre, vitamin C and iron were significantly less than the recommended RDA. There was no difference in protein intake. Only 5.7% of males and 16.7% of females reached the recommended energy allowance. The recommended protein allowance was reached by 43.4% males and 44.4% females and 41.5% males and 38.9% females consumed more than the upper limit of the recommended fat intake. Intake of major nutrients was also significantly less when compared to the national average intake. On bivariate analysis, the factors affecting these inadequacies were found to be annual per-capita income, dependency on another for livelihood, CD4 counts more than 200/cubic millimeter and absence of antiretroviral therapy. On multivariate analysis, only dependency on another was found to significantly influence energy intake. Dietary intake of many food constituents is significantly less in HIV patients than that recommended. Dietary counselling and efforts to improve food security are important in management of these patients.

    Objective To evaluate the value of the clinical use of CT perfusion imaging (CTPI) and CT subtraction angiography (CTSA) for diagnosing acute ischemic cerebrovascular disease (AICVD). Methods Twenty-four patients with AICVD onset within 24 hours were examined with regular CT, CTPI, and CTSA. Some cases received CTPI, magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), digital subtraction angiography (DSA) or single photon emission computer tomography (SPECT) during follow-up examinations.Results Of the 24 cases, 11 had negative results from regular CT scans 3-6 hours after onset of stroke in 6 cases, 6-12 hours in 3 cases, and 12-24 hours in 2 cases. Ten of these cases were then confirmed by CTPI as having ischemic lesions, 2 with middle cerebral artery occlusion (MCAO), and 1 case with transient ischemic attack (TIA) with CTPI negative. Of the 24 cases, 13 had positive results from regular CT, 9 were diagnosed with ischemic lesions larger by using CTPI than regular CT, 1 case had MCAO and 1 had internal carotid artery occlusion (ICAO). There were 4 cases with ischemic lesions observed with regular CT having nearly the same range as that of lacunar infarctions using CTPI. Another 4 cases had more than 2 lesion areas. The peak time (PT), mean transit time (MTT) and relative flow (RF) of 24 cases were markedly different. The sides of ischemic lesions compared to each other and the core of the lesion compared to peripheral zones were also altered significantly (P<0.01).Conclusions Combined CTPI with CTSA can detect acute ischemic lesions at early and hyper-early stages and could distinguish between TIA, lacunar infarction and a larger area of infarction. Using semiquantitative blood perfusion analysis status, CTPI with CTSA could define position, area and range of the ischemic lesion and penumbra. These scans can also analyze the brain blood perfusion status. It is important to early diagnose the occlusion of the entire division of the internal

    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

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.

    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...

    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 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.

    The assessment of daily dietary phosphorus (P) intake is a major concern in human nutrition because of its relationship with Ca and Mg metabolism and osteoporosis. Within this context, we hypothesized that several of the methods available for the assessment of daily dietary intake of P are equally accurate and reliable, although few studies have been conducted to confirm this. The aim of this study then was to evaluate daily dietary P intake, which we did by 3 methods: duplicate portion sampling of 108 hospital meals, combined either with spectrophotometric analysis or the use of food composition tables, and 24-hour dietary recall for 3 consecutive days plus the use of food composition tables. The mean P daily dietary intakes found were 1106 ± 221, 1480 ± 221, and 1515 ± 223 mg/d, respectively. Daily dietary intake of P determined by spectrophotometric analysis was significantly lower (P < .001) and closer to dietary reference intakes for adolescents aged from 14 to 18 years (88.5%) and adult subjects (158.1%) compared with the other 2 methods. Duplicate portion sampling with P analysis takes into account the influence of technological and cooking processes on the P content of foods and meals and therefore afforded the most accurate and reliable P daily dietary intakes. The use of referred food composition tables overestimated daily dietary P intake. No adverse effects in relation to P nutrition (deficiencies or toxic effects) were encountered.

    Full Text Available Background & Objective: Obesity and being overweight are one of current nutritional disorders found in many developed and developing countries such as Iran, it seems that recently the role of carbohydrates in the formation of such illness has been considered. Studies conducted in the field of obesity and quality and quantity of carbohydrate (glycemic index and glycemic load have had inconsistent results. Therefore, This study evaluates the relationship between dietary glycemic index and glycemic load and some indicators of obesity. Material & Methods: The subjects were 95 healthy Iranian females aged 25-55 y .dietary GI, GL assessed from six24 hour food recalls. Anthropometric measurements were taken according to standard methods. Information such as history of disease and genetics was collected by a questionnaire. Independent sample t test, correlation confident ، one–way ANOVA Were used to investigate the correlation between dietary glycemic index and glycemic load and anthropometric measurements. Results: The mean dietary GI was 72.8 and the mean dietary GL was 154.4. After making the necessary adjustments for potential dietary and non-dietary confounding factors, no significant association was seen between dietary GI, GL and BMI, waist circumference, waist to hip ratio in healthy women. Conclusion: The fact that there was no relation between dietary GI and GL and anthropometric measurements in healthy women may be due to the fact that results obtained from overweight samples were not reported in the current study.

    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.

    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.

    Several studies have been conducted on dietary patterns based on carbohydrate nutrition in Asian populations. We examined the cross-sectional associations in dietary patterns based on carbohydrate nutrition, including the glycemic index (GI) with dyslipidemia and diabetes among the Korean adult population. We analyzed 9,725 subjects (3,795 men and 5,930 women, ≥ 20 years) from the Fourth Korea National Health and Nutrition Examination Survey. Dietary information was collected using single 24-hour recall. Reduced rank regression was used to derive dietary patterns from 22 food groups as predictor variables and four dietary factors related to the quantity and quality of carbohydrates as response variables. Two dietary patterns were identified: 1) the balanced pattern was characterized by high intake of various kinds of foods including white rice, and 2) the rice-oriented pattern was characterized by a high intake of white rice but low intake of vegetables, fruits, meat, and dairy products. Both patterns had considerable amounts of total carbohydrate, but GI values differed. The rice-oriented pattern was positively associated with hypertriglyceridemia in men and low high density lipoprotein-cholesterol in both men and women. The balanced pattern had no overall significant association with the prevalence of dyslipidemia or diabetes, however, men with energy intake above the median showed a reduced prevalence of diabetes across quintiles of balanced pattern scores. The results show that dietary patterns based on carbohydrate nutrition are associated with prevalence of dyslipidemia and diabetes in the Korean adult population. PMID:22977690

    Full Text Available 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.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.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.CT perfusion is a very useful indicator for prediction and selection patients in early stages of acute pancreatitis who are at risk of developing pancreatic and/or peripancreatic

    Full Text Available Objective. Central blood pressure (BP and vascular indices estimated noninvasively over the 24 hours were compared between normotensive volunteers and hypertensive patients by a pulse wave analysis of ambulatory blood pressure recordings. Methods. Digitalized waveforms obtained during each brachial oscillometric BP measurement were stored in the device memory and analyzed by the validated Vasotens technology. Averages for the 24 hours and for the awake and asleep subperiods were computed. Results. 142 normotensives and 661 hypertensives were evaluated. 24-hour central BP, pulse wave velocity (PWV, and augmentation index (AI were significantly higher in the hypertensive group than in the normotensive group (119.3 versus 105.6 mmHg for systolic BP, 75.6 versus 72.3 mmHg for diastolic BP, 10.3 versus 10.0 m/sec for aortic PWV, −9.7 versus −40.7% for peripheral AI, and 24.7 versus 11.0% for aortic AI, whereas reflected wave transit time (RWTT was significantly lower in hypertensive patients (126.6 versus 139.0 ms. After adjusting for confounding factors a statistically significant between-group difference was still observed for central BP, RWTT, and peripheral AI. All estimates displayed a typical circadian rhythm. Conclusions. Noninvasive assessment of 24-hour arterial stiffness and central hemodynamics in daily life dynamic conditions may help in assessing the arterial function impairment in hypertensive patients.

    Bath water samples were collected from 116 hot springs, 197 public bathhouses, and 38 24-hour home baths in Nagano Prefecture, Japan, during the period of April 2009 to November 2011, for determining the presence and extent of contamination with Legionella and nontuberculous mycobacteria. Cultures positive for Legionella were observed in 123 of the 3,314 bath water samples examined. The distribution and abundance of Legionella and/or combined contamination with Legionella and nontuberculous mycobacteria were investigated to clarify the contamination levels. The abundance of Legionella was demonstrated to correlate considerably with the levels of combined contamination with Legionella and nontuberculous mycobacteria. Legionella spp. were obtained from 61% of the water samples from 24-hour home baths, but only from 3% of the samples from public bathhouses and hot springs. This is despite the fact that a few outbreaks of Legionnaires' disease in Nagano Prefecture as well as other regions of Japan have been traced to bath water contamination. The comparatively higher rate of contamination of the 24-hour home baths is a matter of concern. It is therefore advisable to routinely implement good maintenance of the water basins, particularly of the 24-hour home baths.

    Time-domain heart rate variability (HRV) parameters and the correlation between echocardiography and Holter examinations in dogs with myxomatous mitral valve disease (MMVD) were determined. Holter examination was also performed at different time frames: an entire 24-hour period, a four-hour period during sleep, and a four-hour period while awake. Ten healthy (control group) and 28 MMVD dogs, 15 with and 13 without heart failure, were evaluated. The SDANN (sd of the mean normal RR intervals for all five-minute segments during 24-hour Holter) and pNN(50) (percentage of differences between adjacent normal RR intervals that are >50 ms computed over 24-hour Holter) variables were significantly lower in the dogs with MMVD heart failure. The differences in HRV between the groups were only detected during the 24-hour evaluation period (PHolter and echocardiography examinations when considering pNN(50), SDANN, and LA/AO (left atrial to aortic root ratio) (r=0.92; P<0.05), indicating that both are important in evaluating MMVD dogs. SDANN and pNN(50) are measures of parasympathetic control of the heart, and thus, it is possible to infer that the MMVD dogs exhibit parasympathetic withdrawal during the development of heart failure.

    Full Text Available Background: Diabetic nephropathy is the major cause for chronic renal failure (CRF and proteinuria is an independent risk factor for end stage renal disease. Hence, early identification and quantification of proteinuria is of prime importance in the diagnosis and management. Methods: This study was conducted amongst 42 diabetic subjects from HSK hospital, Bagalkot. Twenty four-hour urine protein and random urine protein to creatinine ratio (P:C was determined. Pearson′s correlation, sensitivity, specificity, positive and negative predictive values were determined using 24-hour urinary protein as a gold standard for spot urine P:C ratio. ROC curve and area under curve was also determined using SPSS (11.5 software. All the results were expressed in mean±SD. Results: Forty two diabetes mellitus patients participated in this study. The average of 24 hour urinary protein was 1.6 ± 1.7 gm/day. The spot urine P:C ratio was 1.27 ± 1.55. There was a positive correlation between 24 hours urinary protein and spot urine P:C ratio (r = 0.925, p < 0.0001. The area under the ROC curve for urine P:C ratio at various cutoff was 0.947 (95% confidence interval: 0.831-0.992, p < 0.0001. The sensitivity and specificity was 80.65% and 100% respectively at P:C ratio cutoff of 0.3. Conclusions: The random urine P:C ratio predicts the amount of 24-hour urinary protein excretion with high accuracy. Hence it can be used as a faster diagnostic substitute for 24-hour urinary protein estimation.

    Full Text Available The objective of this study was to determine sources and patterns of antioxidant and flavonoid intakes in the elderly (61–74 yrs in comparison with young (20–40 yrs and middle age (41–60 yrs groups in a cross-sectional study. More than 6000 subjects of both genders, aged 20–74 years, participants of the National Multicenter Health Survey (WOBASZ took part in this study. Daily food consumption was estimated by the single 24-hour dietary recall. Dietary total antioxidant capacity (TAC and flavonoid content (FC were calculated according to the amount of food consumed by the participants combined with antioxidant capacity and flavonoid contents in foods. Food consumption, dietary TAC, and FC were significantly lower in the elderly, especially elderly women in comparison to the young and middle age groups. The consumption of tea, coffee, and apples was associated with the largest contribution to dietary TAC and FC in all participants. Despite high nutrient density of the energy-adjusted diet of ageing people, the elderly consumed the lowest amounts of antioxidants and flavonoids due to the lowest food intake.

    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.

    Hypertension is a prevalent cardiovascular disease, the important modifiable risk factor of which is diet. The aim of this study was to derive dietary patterns and to test associations with self-reported hypertension and other characteristics, namely demographic, socioeconomic, and lifestyle factors. Data were obtained from the population-based cross-sectional study titled Health Survey of the City of São Paulo, with a random sample of residents of the city of São Paulo, Brazil, aged older than 20 years of both sexes (n=1,102). In 2008, a structured questionnaire with information about socioeconomic, anthropometric, lifestyle, and dietary factors was applied. Dietary intake was estimated by two 24-hour dietary recalls, adjusted by Multiple Source Method. Dietary patterns were obtained through exploratory principal component factor analysis. Poisson regression was used to assess relationships. Three dietary patterns were identified: prudent (fruits, vegetables, whole-grain bread, white cheeses, juices, reduced-fat milk/nonfat milk), traditional (rice, beans, bread/toast/crackers, butter/margarine, whole milk, coffee/teas, sugar), and modern (sodas, pastries/sandwiches/pizzas, yellow cheeses, pastas, sauces, alcoholic beverages, sweets, processed meats). Hypertension and demographic, socioeconomic, and lifestyle factors, as well as the presence of health insurance, were associated with adherence to one or more identified dietary patterns. These results suggest the existence of a target audience for planning and executing public policies of food and nutrition to prevent and control hypertension.

    The 20-minute {sup 99m}Tc-pertechnetate uptake became readily available for routine use and it replaced {sup 131}I for thyroid imaging. However measuring thyroid uptake during a 5-minute minimizes pertechnetate uptake by the salivary glands and presence of contaminated saliva from those glands in to the pharynx and esophagus. A study was carried out to determine the suitability of the utility of a 5-minute and 20-minute interval from administration of {sup 99m}Tc-pertechnetate to imaging and uptake measurement as a replacement for the 24 hour standard originally established with {sup 131}I, and to evaluate the relationship between 5-minute {sup 99m}Tc-pertechnetate uptake and other thyroid functions. A 5-minute and 20-minute uptake of {sup 99m}Tc-pertechnetate were measured in 70 patients with thyroid disease at Yeungnam University Hospital from March 1, 1991 to Feb. 29, 1992. The results were as follows. 1) The 5-minute {sup 99m}Tc-pertechnetate uptake in Graves' disease, Hashimoto's thyroiditis, simple goiter non toxic nodular goiter, subacute thyroiditis and euthyroid were 18.2%, 14.6%, 2.8%, 3.2%, 1.2% and 1.1%, respectively. There was a significant difference between the mean of the euthyroid group and the mean of the Graves' disease. So differentiation between them can be easily made. 2) The 5 minute {sup 99m}Tc- pertechnetate thyroid uptake was well correlated with 24 hour {sup 131}I thyroid uptake (r=0.75, p<0.001). These data provided an equation for estimating the 24 hour uptake of iodide given the 5 minute pertechnetate uptake: Estimated 24-hour '1{sup 31}I thyroid Uptake = 7.188{sup *}In (5 minute {sup 99m}Tc-Pertechnetate uptake)+16.94 3) The 20-minute {sup 99m}Tc-pertechnetate thyroid uptake was well correlated with 24-hour {sup 131}I uptake (r=0.72, p<0.001) and 5-minute {sup 99m}Tc-pertechnetate thyroid uptake (r=0.96, p<0.001). 4) In the Graves' disease, The 5-minute {sup 99m}Tc-pertechnetate thyroid uptake was well

    Urinary homovanillic acid (HVA) and vanillylmandelic acid (VMA) levels were determined in random samples and in 24-hour collections from 13 patients with neuroblastoma and 22 patients without neuroblastoma. Random sample levels were compared with levels in 24-hour collections and showed a positive correlation of 95% for HVA (N = 59) and 93% for VMA (N = 52). No false positives or false negatives occurred using random samples for diagnosis. Nonneuroblastoma (normal) HVA (N = 126) and VMA (N = 119) levels are reported for different age groups. Sequential random HVA and VMA determinations in patients with neuroblastoma during and after therapy are shown. Random urinary HVA and VMA levels are shown to be adequate for utilization in the diagnosis of neuroblastoma and sequential determinations of random HVA and VMA are shown to be helpful in the follow-up of those patients.

    In two experiments we tested whether providing retrieval opportunities while people were multitasking would improve memory for names. College students (n=195) in Experiment 1 did addition problems and intermittently were "introduced" to 12 face-name pairs to learn. For half the names students were given three within-list retrieval opportunities. Name recall (cued with the faces) was tested either immediately or after 24 hours. Retrieval opportunities improved name recall with both immediate and delayed tests. Experiment 2 more closely resembled the multitasking required in a real-life social situation. College students (n=98) viewed a videotape and were asked to learn the names of 12 dormitory residents who were introduced during an ongoing conversation. Retrieval opportunities were provided for 8 of the 12 residents by having them appear three additional times in the video without repeating their names. Retrieval opportunities improved name recall, but the effect was much smaller than in Experiment 1. The present research demonstrates that distributed retrieval can be effective when people are multitasking including when the multitasking involves a conversation.

    This randomized, double-blind, placebo-controlled study evaluated the early effects of canagliflozin on blood pressure (BP) in patients with type 2 diabetes mellitus (T2DM) and hypertension. Patients were randomized to canagliflozin 300 mg, canagliflozin 100 mg, or placebo for 6 weeks and underwent 24-hour ambulatory BP monitoring before randomization, on day 1 of treatment, and after 6 weeks. The primary endpoint was change in mean 24-hour systolic BP (SBP) from baseline to week 6. Overall, 169 patients were included (mean age, 58.6 years; glycated hemoglobin, 8.1%; seated BP 138.5/82.7 mm Hg). At week 6, canagliflozin 300 mg provided greater reductions in mean 24-hour SBP than placebo (least squares mean -6.2 vs -1.2 mm Hg, respectively; P=.006). Numerical reductions in SBP were observed with canagliflozin 100 mg. Canagliflozin was generally well tolerated, with side effects similar to those reported in previous studies. These results suggest that canagliflozin rapidly reduces BP in patients with T2DM and hypertension.

    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.

    The long-term relationship between 24-hour ambulatory blood pressure (ABP) and office BP in patients on therapy is not well documented. From a registry we included all patients in whom antihypertensive therapy needed to be uptitrated. Drug treatment included the direct renin inhibitor aliskiren or an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker or drugs not blocking the renin-angiotensin system, alone or on top of an existing drug regimen. In all patients, office BP and 24-hour ABP were obtained at baseline and after 1 year with validated devices. In the study population of 2722 patients, there was a good correlation between the change in office BP and 24-hour ABP (systolic: r=0.39; PABP in a 1:1 fashion, for example, a decrease of 10, 20, and 30 mm Hg corresponded to a decrease of ≈7.2, 10.5, and 13.9 mm Hg in systolic ABP, respectively. The disproportionally greater decrease in systolic office BP compared with ABP was dependent on the level of the pretreatment BP, which was consistently higher for office BP than ABP. The white coat effect (difference between office BP and ABP) was on average 10/5 mm Hg lower 1 year after intensifying treatment and the magnitude of that was also dependent on pretreatment BP. There was a disproportionally greater decrease in systolic office BP than in ABP, which for both office BP and ABP seemed to depend on the pretreatment BP level.

    This study was conducted as a part of long-term DAGIS project that aims to improve the health behaviors and diminish socioeconomic inequalities in health behaviors among preschool children in Finland. A large cross-sectional survey is conducted in autumn 2015. Children (N=800, aged 3-6 years wear Actigraph WGT3X-BT accelerometer for seven days, 24 hours per day. Simultaneously with accelerometer use, parents fill in diary with informing the user experiences of accelerometer and possible non-wearing times. Parents are advised that the child wears accelerometer 24 hours and remove the belt only when in water (e.g. in shower. The accelerometer data are checked straight after data collection. Choi (2011 wear time analyses are conducted for data. The device acceptability, compliance for wearing times and reported barriers for using accelerometer 24 hours in seven days among 3-6-year-old children are reported. Conclusions This study provides new information about the usability of wearable activity monitors among 3-6-year-old children, an age group that is less studied.

    A dietary survey was conducted over three consecutive days by using 24-hour dietary recall in the Pearl River Delta of South China to investigate the dietary consumption status. A total of 1702 food samples, 22 food groups, were collected, and aluminium concentrations of foods were determined by using ICP-MS. Weekly dietary exposure to aluminium of the average urban residents of South China was estimated to be 1.5 mg kg⁻¹ body weight, which amounted to 76% of the provisional tolerable weekly intake. Wheat-made products (53.5%) contributed most to the dietary exposure, followed by vegetables (12.2%). The high-level consumers' weekly exposure to aluminium was 11.1 mg kg⁻¹ body weight, which amounted to 407% of the provisional tolerable weekly intake. The results indicated that the general urban residents in South China might be safe from aluminium exposure, but the high-level consumers might be at some risk of aluminium exposure. The foods contributing to aluminium exposure were processed food with aluminium-containing food additives. It is necessary to take effective measures to control the overuse of aluminium-containing food additives.

    An elevation in symptoms of depression has previously been associated with greater accuracy of reported dietary intake, however this association has not been investigated among individuals with a diagnosis of major depressive disorder. The purpose of this study was to investigate reporting accuracy of dietary intake among a group of women with major depressive disorder in order to determine if reporting accuracy is similarly associated with depressive symptoms among depressed women. Reporting accuracy of dietary intake was calculated based on three 24-hour phone-delivered dietary recalls from the baseline phase of a randomized trial of weight loss treatment for 161 obese women with major depressive disorder. Regression models indicated that higher severity of depressive symptoms was associated with greater reporting accuracy, even when controlling for other factors traditionally associated with reporting accuracy (coefficient  =  0.01 95% CI = 0.01 - 0.02). Seventeen percent of the sample was classified as low energy reporters. Reporting accuracy of dietary intake increases along with depressive symptoms, even among individuals with major depressive disorder. These results suggest that any study investigating associations between diet quality and depression should also include an index of reporting accuracy of dietary intake as accuracy varies with the severity of depressive symptoms.

    Residents in training, medical students and other staff in surgical sector, emergency room (ER) and intensive care unit (ICU) or Burn Unit face a multitude of questions regarding burn care. Treatment of burns is not always straightforward. Furthermore, National and International guidelines differ from one region to another. On one hand, it is important to understand pathophysiology, classification of burns, surgical treatment, and the latest updates in burn science. On the other hand, the clinical situation for treating these cases needs clear guidelines to cover every single aspect during the treatment procedure. Thus, 10 questions have been organised and discussed in a step-by-step form in order to achieve the excellence of education and the optimal treatment of burn injuries in the first 24 hours. These 10 questions will clearly discuss referral criteria to the burn unit, primary and secondary survey, estimation of the total burned surface area (%TBSA) and the degree of burns as well as resuscitation process, routine interventions, laboratory tests, indications of Bronchoscopy and special considerations for Inhalation trauma, immediate consultations and referrals, emergency surgery and admission orders. Understanding and answering the 10 questions will not only cover the management process of Burns during the first 24 hours but also seems to be an interactive clear guide for education purpose.

    Full Text Available Background and Objectives. Swallowing difficulty is considered one of the nonspecific symptoms that many patients with laryngopharyngeal reflux complain of. However, the relationship between laryngopharyngeal reflux and swallowing problems is not clear. The purpose of this work is to explore correlation between swallowing-related problems and laryngopharyngeal reflux (LPR in a group of patients diagnosed with oropharyngeal pH monitoring and to study the effect of laryngopharyngeal reflux on the patients’ self-perception of swallowing problems. Methods. 44 patients complaining of reflux-related problems were included in the study. Patients underwent 24-hour oropharyngeal pH monitoring and were divided into positive and negative LPR groups based on the pH monitoring results. All patient filled out the Dysphagia Handicap Index (DHI and Reflux Symptom Index (RSI questionnaires. Comparison was made between the positive and negative LPR groups regarding the results of the DHI and RSI ratings. Also, correlation between DHI scores, RSI scores, and pH monitoring results was studied. Results. Significant difference was reported between positive and negative LPR groups regarding DHI scores, RSI scores, and overall rating of swallowing difficulty. There was significant correlation demonstrated between DHI scores, RSI scores, and 24-hour oropharyngeal pH results. Conclusion. Laryngopharyngeal reflux appears to have a significant impact on patients’ self-perception of swallowing problems as measured by DHI.

    Food-borne diseases caused by Salmonella represent a worldwide public health problem. Salmonella must be absent in an established amount depending on the kind of the product and usually cultural methods have to be applied to evaluate the compliance of the products. ISO 6579:2002 in Europe and FSIS MLG 4.04.:2008 in the USA have usually been employed to detect Salmonella in meat, poultry and egg products. A Real Time PCR method using probes has recently been validated against the NMKL (Nordic Committee on Food Analysis) standard method. This method has been modified using the less expensive Sybr Green Real Time PCR approach and applied directly in the 18 hours preenrichment broth for the purpose of detecting Salmonella in meat products in less than 24 hours. The purpose of this study was to: - compare the effectiveness of ISO and FSIS cultural methods; - develop a new 24 hour duplex Sybr Green Real Time PCR-melting curve analysis; - evaluate the performance of Salmonella, Standard Method, Rapid Method, SYBR Green Real Time PCR. The equivalence between ISO and FSIS methods was demonstrated and the use of SYBR Green Real Time PCR as a screening tool for negative results seems appealing especially to evaluate compliance with the HACCP systems.

    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. The journal in which the study is published has no impact. Information technology use may increase in the future allowing other methods and forms of dietary assessment to be used efficiently.

    The purpose of this study was to develop techniques to predictably return patients receiving inframammary and axillary, subpectoral breast augmentation to full normal activities within 24 hours of their primary breast augmentation. This 5-year study applies motion and time study principles to refine practices in augmentation mammaplasty to reduce perioperative morbidity and shorten patient recovery. Retrospective data for operative times, medications administered, recovery times, times to discharge, and time to return to normal activities were collected from patient chart reviews and patient contacts from 1982 to 1984 (group 1, n = 16, axillary partial retropectoral augmentations) and 1990 (group 2, n = 16, inframammary partial retropectoral augmentations). Videotapes from operative procedures of groups 1 and 2 were analyzed with macromotion and micromotion study principles, and tables of events were formulated for all operating room personnel, detailing every step of each function they performed. The events tables were then refined into detailed scripts by using motion and time study principles. Scripts were used for surgeon and personnel training and for reference during operative procedures. Extensive changes in all aspects of patient care, including patient education, preparation, operative planning, implant selection, anesthesia techniques, surgical techniques, instrumentation, and postoperative care derived from data and videotape studies of patients in groups 1 and 2 were then applied to a third group of patients (group 3), collecting prospective data over a 3-year period (1998 to 2000). Group 3 (n = 627) data included timed events, medications, and time to return to normal activities. Patients in group 3 had substantially shorter anesthesia, operation, and postanesthesia care unit times and time to discharge and time to return to normal activities compared with groups 1 and 2. Of the patients in group 3, 96 percent were able to return to normal activities

    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.

    Full Text Available Mikhail Y Ledyaev, Olga V Stepanova, Anastasia M Ledyaeva Department of Pediatric Disease, Volgograd State Medical University, Volgograd, Russian Federation Background: Automatic 24-hour ambulatory blood pressure (BP monitoring (ABPM is a basic procedure performed in adults with arterial hypertension, but ABPM monitors have become widely used in pediatric practice only recently. The main problem is the lack of common normative data sets for ABPM in children and the small number of appropriate monitors that can be used for analysis of the 24-hour BP profile in this age group. The aim of this study was to validate the BPLab® ABPM monitor according to the 1993 British Hypertension Society (BHS-93 protocol, as well as to work out solutions regarding the feasibility of this device in pediatric practice. Methods: Our study included 30 children of both sexes and aged 5–15 years, ie, “older” children according to the BHS-93 protocol. Before starting the study, we obtained ethical approval from the regional scientific ethics committee. All participants and their parents signed their written consent for participation in the study. The data were simultaneously obtained by three experts, who had completed a noninvasive BP measurement training course. BP values were measured using the Korotkoff auscultatory method (Phase I for systolic BP and Phase V for diastolic BP. Discrepancies in the systolic and diastolic BP measurements (n=180; 90 for each expert were analyzed according to the criteria specified in the BHS-93 protocol. Results: The device was graded “A” for both systolic BP and diastolic BP according to the criteria of the BHS-93 protocol. Conclusion: The BPLab ABPM device may be recommended for extensive pediatric use. Keywords: ambulatory blood pressure monitoring, children, device, validation

    Aim of this study was to evaluate possible relationship between parameters of blood pressure (BP) profile and glomerular filtration rate in patients (pts) with I-II stage essential hypertension (EH). Material and methods. We studied 120 pts (97 men), aged 23-65 (50,2+/-0,6) years with I (n=98) and II (n=22) stage EH. In BP profile (SL-90207) we calculated 24-hour, daytime, nighttime values of systolic, diastolic, pulse pressures (SBP, DBP, PP), time load (TL), variability and nocturnal fall (NF) of BP. The state of renal function was assessed by measurement of glomerular filtration rate (GFR) calculated by the Cockcroft formula. Results. After nonlinear statistical analysis by Gauss-Newton all patients were divided into three groups according to GFR tertiles. Significant differences were found between these groups by 24-hour, nighttime and daytime values of SBP and DBP. Values of SBP were the lowest in group II. In group II lowest values of PP were also observed, but statistically significant differences were found only in nocturnal PP values between groups II and III. There were no significant differences between groups by TL and NF of BP. In group Ill (high GFR) variability of daytime values of SBP and DBF were significantly higher. Univariate correlation analysis showed statistically significant negative relationship between GFR and nocturnal PP in patients with lowest level of GFR. Positive correlations between nocturnal values of PP and GFR in groups II and III were also observed. Conclusion. These results indicated the presence of strong relationship between high values of nocturnal PP and decreasing of glomerular filtration rate in patients with EH and thus confirmed significance of "constant" and "dynamic" components of pressure load as a marker of impairment of renal function.

    High platelet reactivity and high platelet turnover have been implicated in incomplete platelet inhibition during immediate-release acetylsalicylic acid therapy in patients with type 2 diabetes mellitus (DM). An extended-release acetylsalicylic acid (ER-ASA; Durlaza) formulation was developed to provide 24-hour antithrombotic effects with once-daily dosing. The objective of the study was to evaluate the antiplatelet effects of ER-ASA in patients with DM. In this open-label, single-center study, patients with DM (n = 40) and multiple cardiovascular risk factors received ER-ASA 162.5 mg/day for 14 ± 4 days. Multiple platelet function tests, serum and urinary thromboxane B2 metabolites, prostacyclin metabolite, and high-sensitive C-reactive protein levels were assessed at 1, 12, 16, and 24 hours post-dose. Patients with high platelet turnover and/or high platelet reactivity were treated with ER-ASA 325 mg/day for 14 ± 4 days, and laboratory analyses were repeated. All patients responded to ER-ASA 162.5 mg/day as measured by arachidonic acid-induced aggregation, and there was no loss of the platelet inhibitory effect of ER-ASA 162.5 mg/day over 24 hours post-dose (p = not significant). The antiplatelet effect was sustained over 24 hours for all platelet function measurements. Mean 1- to 24-hour serum thromboxane B2 levels were low with both doses and were lower with ER-ASA 325 mg/day compared with 162.5 mg/day therapy (p = 0.002). In conclusion, ER-ASA 162.5 mg daily dose provided sustained antiplatelet effects over 24 hours in patients with type 2 DM and multiple cardiovascular risk factors and had a favorable tolerability profile.

    A first-line approach to treat anxiety disorders is exposure-based therapy, which relies on extinction processes such as repeatedly exposing the patient to stimuli (conditioned stimuli; CS) associated with the traumatic, fear-related memory. However, a significant number of patients fail to maintain their gains, partly attributed to the fact that this inhibitory learning and its maintenance is temporary and conditioned fear responses can return. Animal studies have shown that activation of the cannabinoid system during extinction learning enhances fear extinction and its retention. Specifically, CB1 receptor agonists, such as Δ9-tetrahydrocannibinol (THC), can facilitate extinction recall by preventing recovery of extinguished fear in rats. However, this phenomenon has not been investigated in humans. We conducted a study using a randomized, double-blind, placebo-controlled, between-subjects design, coupling a standard Pavlovian fear extinction paradigm and simultaneous skin conductance response (SCR) recording with an acute pharmacological challenge with oral dronabinol (synthetic THC) or placebo (PBO) 2 hours prior to extinction learning in 29 healthy adult volunteers (THC = 14; PBO = 15) and tested extinction retention 24 hours after extinction learning. Compared to subjects that received PBO, subjects that received THC showed low SCR to a previously extinguished CS when extinction memory recall was tested 24 hours after extinction learning, suggesting that THC prevented the recovery of fear. These results provide the first evidence that pharmacological enhancement of extinction learning is feasible in humans using cannabinoid system modulators, which may thus warrant further development and clinical testing.

  15. Recalling academic tasks

    This study was focused on what students remembered about five middle school science tasks when they were juniors and seniors in high school. Descriptions of the five tasks were reconstructed from available artifacts and teachers' records, notes and recollections. Three of the five tasks were "authentic" in the sense that students were asked to duplicate the decisions practitioners make in the adult world. The other two tasks were more typical school tasks involving note taking and preparation for a quiz. All five tasks, however, involved use of computers. Students were interviewed to examine what and how well they recalled the tasks and what forms or patterns of recall existed. Analysis of their responses indicated that different kinds of tasks produced different levels of recall. Authentically situated tasks were remembered much better than routine school tasks. Further, authentic tasks centered on design elements were recalled better than those for which design was not as pivotal. Patterns of recall indicated that participants most often recalled the decisions they made, the scenarios of the authentically situated tasks, the consequences of their tasks and the social contexts of the classroom. Task events, in other words, appeared to form a framework upon which students constructed stories of the tasks. The more salient the events, the richer the story, the deeper and more detailed the recall of the task. Thus, authentic tasks appeared to lend themselves to creating stories better than regular school tasks and therefore such tasks were recalled better. Implications of these patterns of recall are discussed with respect to issues of school learning and assessment.

    Full Text Available Background: The metabolic syndrome is a complex metabolic disturbance due to an interaction between genetic factors, poor dietary habits and physical inactivity. Aims: To investigate the role of dietary intake on the prevalence of the metabolic syndrome in a population of elderly, socially active women in Brazil. Patients and Methods : A total of 284 women with mean age 69.3 ± 6.3 years were evaluated in a cross-sectional retrospective study. The metabolic syndrome was diagnosed according to criteria of the International Diabetes Federation. The dietary intake was evaluated through a questionnaire for 24-hour dietary recall. The groups with or without the metabolic syndrome were compared for dietary intake and risk factors for metabolic syndrome by the multiple regression model adjusted for age, smoking, physical activity, educational level, total energy intake and fiber contents of the diet. The odds ratio for the presence of the metabolic syndrome was calculated for each nutrient by quartile for total energy intake adjusted by the residue method. Results: The prevalence of metabolic syndrome was 32% in the sample. There was not found any association between dietary intake, including all macronutrients and several micronutrients, and the presence of metabolic syndrome. Conclusion : No associations were observed between nutritional factors and the prevalence of the metabolic syndrome in elderly women, a result possibly due to the fact that these factors have an influence in earlier phases of life, or to a recent modification of dietary habits, which however was not able to prevent the establishment of the syndrome.

    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.

    Fast-food restaurants are more prevalent in lower income and predominately African American neighborhoods, where consumption of fast-food is also higher. In general populations, fast-food consumption is related to less healthy dietary intake. This cross-sectional study examined the hypotheses that greater fast-food consumption is associated with less healthy dietary intake and poorer diet quality in overweight and obese women (N=196, 25–51 years, 87% African American) recruited from financially disadvantaged Census tracts. Dietary intake and diet quality (Alternate Healthy Eating Index, AHEI) were assessed via three 24-hour dietary recalls. Linear regression models tested the association between fast-food consumption and each outcome (Model 1). Model 2 added sociodemographics and physical activity. Model 3 added total caloric intake. Fast-food consumption was significantly associated with total caloric intake; total intake of meat, grains, sweetened beverages, dairy, fiber, cholesterol, sodium, and added sugar; and percent of calories from total fat, saturated fat, and trans fatty acids. Statistically significant associations remained in Model 2 but most were not significant in Model 3. Fast-food consumption was not associated with diet quality (AHEI) in any model. In this at-risk sample, fast-food consumption was associated with more negative dietary practices. Significant associations generally disappeared when controlling for total caloric intake, suggesting that women who eat more fast-food have higher total caloric intakes as a result of increased consumption of unhealthy rather than healthy foods.

  4. 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

    In patients treated with implantable cardioverter defibrillator (ICD), prediction of both overall survival and occurrence of shocks is important if improved patient selection is desired. We prospectively studied the predictive value of biomarkers and indexes of cardiac and renal function and spectral microvolt T-wave alternans testing and 24-hour Holter variables in a population who underwent first ICD implantation. Consecutive patients in sinus rhythm with ischemic or dilated cardiomyopathy scheduled for primary or secondary prophylactic ICD implantation were enrolled. Exercise microvolt T-wave alternans and 24-hour Holter for number of ventricular premature contractions (VPCs), deceleration capacity, heart rate variability, and heart rate turbulence were done. Death of any cause and first appropriate ICD shock were defined as end points. Over 33 ± 15 months of follow-up, 36 of 253 patients (14%) received appropriate shocks and 39 of 253 patients (15%) died. Only 3 of 253 patients (1%) died after receiving at least 1 appropriate shock. In univariate analyses, New York Heart Association class, ejection fraction, N-terminal pro brain-type natriuretic peptide (NT-proBNP), renal function, ICD indication, deceleration capacity, heart rate variability, and heart rate turbulence were predictive of all-cause mortality and VPC number and deceleration capacity predicted first appropriate shock. NT-proBNP (≥1,600 pg/ml) was identified as the only independent predictor of all-cause mortality (hazard ratio 3.0, confidence interval 1.3 to 7.3, p = 0.014). In contrast, VPC number predicted appropriate shocks (hazard ratio 2.3, confidence interval 1.0 to 5.5, p = 0.047) as the only independent risk marker. In conclusion, NT-proBNP is a strong independent predictor of mortality in a typical prospective cohort of newly implanted patients with ICD, among many electrocardiographic and clinical variables studied. Number of VPCs was identified as a predictor of appropriate shocks

    Prior studies have documented an association of obesity with chronic pain, but the mechanism explaining the association remains unknown. This study evaluated the degree to which dietary intake of foods with anti-inflammatory effects mediates the relationship of body fat to body pain. Ninety-eight community-residing healthy adults (60% women; mean age = 43.2 ± 15.3 years; range: 20-78 years) participated in a home-based study of home environment, food-related behaviors, health, and adiposity. During a 3-hour home visit evaluation, 3 measures of body fat were collected, including height and weight for calculation of body mass index (BMI). Participants also completed a 24-hour food recall interview and self-report measures of bodily pain (BP; BP subscale from the Medical Outcomes Study Short Form-36) and psychological distress (Hospital Anxiety and Depression Scale). Quality of dietary intake was rated using the Healthy Eating Index-2010. Mediation models were conducted with the PROCESS macro in SAS 9.3. Mean BMI was consistent with obesity (30.4 ± 7.8; range: 18.2-53.3), and BP values (73.2 ± 22.1; range: 0-100) and dietary intake quality (59.4 ± 15.5; range: 26.8-88.1) were consistent with population norms. Modeling in PROCESS revealed that Healthy Eating Index-2010 scores mediated the relationship between BMI and BP (bindirect = -0.34, 95% confidence interval = -0.68 to -0.13). The mediation model remained significant when controlling for biomechanical factors (arthritis/joint pain), medication use, psychological distress, age, and education, and models remained significant using the other 2 body fat measures. Thus, the data indicate that dietary intake of foods with anti-inflammatory effects mediates the relationship of body fat to body pain in healthy men and women.

    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.

    de suspeição do especialista.Introduction: Laryngeal symptoms from the gastroesophageal reflux are increasing and being more common. Studies have shown high association with e "globus", cronic hoarseness and cronic cough. The diagnosis and treatment are different from the well known gastroesophageal reflux disease. Laryngeal endoscopy is the first exam to be done in laryngeal pacients. Laryngeal redness, thickness of space between arytenoids, granuloma, polyp, Reinke's swelling, subglottic's stenosis need a complete clinical investigation. 24 hour pHmetry and manometry are the choice, because its sensibility and espicificity. Aim: compare early clinical and laryngeal finds of laringopharingeal reflux with 24 hours pHmetry and manometry results. Evaluate responses to clinical terapy and dietary. Study design: Clinical prospective: Material and Method: adults with those cronic complaints: dry cough, "globus", to hawk, sialorrhoea, hoarseness, halitosis and choking. Pacients with another patology from airways were excluded. The laryngoscopy was important to select only recent lesions to do 24 hour pHmetry and manometry, and after if necessary try clinical treatment. Results: 83,6% had patologic reflux. More frequent symptoms were: hoarseness (72,5%, to hawk (60,8%, to cough (29,4%, "globus" (23,5% and sialorrhoea (19,6%. Frequency of associated symptoms: two (67,4%; three (41,2% and four (21,5%. 49 pacients have begun treatment with omeprazole and diet: 83,7% became better after 6 months. 95,9% of the treated patients had improved in laryncoscopy. Conclusions: Laryngeal endoscopy and clinical history had good correlation with 24 hour pHmetry and manometry results. Other studies would estabilsh rules to diagnosis and follow patients with laryngeal endoscopy. Working with other professionals is important to solve problems at this pathology.

    Family expenditures on food for children may represent an important barrier to the adoption of healthy feeding practices in populations of low socioeconomic status. The aim of this study was to explore the relationship between cariogenic feeding practices, expenditures on food for children and dental caries. This cross-sectional study included 329 four-year-old children from São Leopoldo in southern Brazil. Cariogenic dietary practices were assessed at 4 years of age using two 24-hour recalls conducted with the children's mothers. Expenditures on food for children were estimated based on all reported food items and the respective amounts ingested. Early childhood caries and severe early childhood caries were assessed by clinical examination at 4 years of age. Cariogenic dietary habits were not associated with lower food expenditures. On the contrary, in multivariable regression analysis, the intake of chocolate (p = 0.007), soft drinks (p = 0.027) and a higher number of meals and snacks per day (p food for children. No statistically significant differences were observed in food expenditures or in the proportion of household income spent on feeding children between caries-free children, those with early childhood caries and those with severe early childhood caries. In conclusion, keeping children free of dental caries does not necessarily increase food expenditures or the proportion of household income spent on feeding children in low-socioeconomic status populations. Some cariogenic dietary practices were associated with greater expenditures on child feeding.

    Full Text Available In the United States, the National School Breakfast (SBP and School Lunch Program (NSLP meals are provided for free or at a reduced price to eligible children, and are a nutrition safety net for low income children. Consuming both meals could provide 58% of daily intake. This paper evaluates the contribution of SBP and NSLP meals to the dietary intakes of 5–18 year old children participating in the National Health and Nutrition Examination Surveys (NHANES from 2007 through 2012. The participants completed 24-hour dietary recalls. Least-square means and standard errors of the mean for energy and food group intakes for the total day and by school meal, and the percent of daily energy and food groups contributed by school meals were computed by analysis of covariance, with BMI, ethnicity, sex, age and poverty level as covariates. Of the 7800 participating children aged 5–18 years in the entire dataset, 448 consumed both SBP-NSLP meals on a weekday. Almost one-half (47% of the day's energy intake was provided by the two school meals. For the major food groups, the contribution of school meals ranged from between 40.6% for vegetables to 77.1% for milk. Overall, these results provide important information on contribution of the SBP and NSLP meals to low income children's daily dietary intake.

    The aim of this in vitro study was to evaluate the influence of different irrigation protocols on the bond strength, at different root depths, of fiber posts cemented with a self-adhesive cement 24 hours after endodontic treatment. Fifty-six bovine incisor roots were endodontically prepared and separated into 7 groups (n = 8) according to irrigation protocols: group 1, sterile saline (control); group 2, chlorhexidine (CHX) gel 2% and saline; group 3, sodium hypochlorite (NaOCl) 5.25% and saline; group 4, CHX and saline (final irrigation with ethylenediaminetetraacetic acid [EDTA] 17%); group 5, NaOCl and saline (final irrigation with EDTA); group 6, CHX and saline (final irrigation with NaOCl and EDTA); and group 7, NaOCl (final irrigation with CHX and EDTA). No statistically significant difference was found among the groups. Within the limitations of this study, it can be concluded that the different irrigation protocols did not influence the bond strength of self-adhesive resin cement, which presented similar behaviors at the 3 root depths studied.

    Full Text Available The aim of the study was to evaluate the effect of repeated semen collection and the substitution of normal egg yolk with clarified egg yolk to commercially produced semen extender on qualitative parameters of frozen-thawed canine semen. Two semen collections were scheduled in a 24-hour interval and in each of six dogs, three 1st and three 2nd collections were performed. The frozen-thawed sperm samples were prepared either with clarified or normal egg yolk and motility and viability were evaluated. The effect of the sequence of semen collection was demonstrated by significant differences in motility and also in viability of sperms both in native and frozen-thawed ejaculate. The percentage of viable sperms was significantly higher in samples from the 2nd compared to the 1st collection. This trend was the same also in motility except in native ejaculate. The addition of clarified egg yolk was beneficial for higher survival of sperms immediately after thawing and also after 30 min of incubation, compared to samples with normal egg yolk. Sperm motility evaluated after thawing was higher in samples with clarified egg yolk, without an apparent connection with semen collection sequence. The decrease of values of the qualitative parameters of sperms observed in the period of 30 min of incubation was significantly slowed down when clarified egg yolk was used. This was especially obvious in samples from the 2nd collection.

    Fluid loading (FL) before Shuttle reentry is a countermeasure currently in use by NASA to improve the orthostatic tolerance of astronauts during reentry and postflight. The fluid load consists of water and salt tablets equivalent to 32 oz (946 ml) of isotonic saline. However, the effectiveness of this countermeasure has been observed to decrease with the duration of spaceflight. The countermeasure's effectiveness may be improved by enhancing fluid retention using analogs of vasopressin such as lypressin (LVP) and desmopressin (dDAVP). In a computer simulation study reported previously, we attempted to assess the improvement in fluid retention obtained by the use of LVP administered before FL. The present study is concerned with the use of dDAVP. In a recent 24-hour, 6 degree head-down tilt (HDT) study involving seven men, dDAVP was found to improve orthostatic tolerance as assessed by both lower body negative pressure (LBNP) and stand tests. The treatment restored Luft's cumulative stress index (cumulative product of magnitude and duration of LBNP) to nearly pre-bedrest level. The heart rate was lower and stroke volume was marginally higher at the same LBNP levels with administration of dDAVP compared to placebo. Lower heart rates were also observed with dDAVP during stand test, despite the lower level of cardiovascular stress. These improvements were seen with only a small but significant increase in plasma volume of approximately 3 percent. This paper presents a computer simulation analysis of some of the results of this HDT study.

    Engaging stakeholders in the development of guidelines and plans for implementation is vital. The purpose of this study was to examine stakeholders' (parents, teachers, exercise professionals, paediatricians, and youth) perceptions of the Canadian 24-Hour Movement Behaviour Guidelines for Children and Youth ("Movement Guidelines"). Stakeholders (n = 104) engaged in semi-structured focus groups or interviews to discuss the perceived acceptability of the guidelines, potential barriers to implementation, and preferred methods and messengers of dissemination. A thematic analysis was conducted. Overall, there was consistent support across all stakeholder groups, with the exception of youth participants, for the Movement Guidelines. Stakeholders identified a range of barriers to the uptake of the guidelines including concerns with accurately defining key terms such as "recreational" screen time; everyday challenges such as financial and time constraints; and the possibility of the Movement Guidelines becoming just another source of stress and guilt for already busy and overwhelmed parents. Participants identified a range of recommended methods and messengers for future dissemination. School and medical settings were the most commonly recommended settings through which dissemination efforts should be delivered. Overall, participants representing a range of stakeholder groups were receptive to the new Movement Guidelines and endorsed their value. In complementing the Movement Guidelines, messaging and resources will need to be developed that address common concerns participants had regarding their dissemination and implementation.

    Objective: To assess and compare the relative efficacy of silk ligation and diathermy coagulation techniques in controlling bleeding during tonsillectomy in the first 24 hours. Methods: This prospective study was conducted at the Department of ENT, Khalifa Gul Nawaz Teaching Hospital, Bannu and this department related consultants’ private clinics from January 1, 2012 to December 31, 2014. The study included 180 cases. All patients included were having history of recurrent, acute tonsillitis, with more than 6–7 episodes in one year, five episodes per year for two years, or three episodes per year for three years. All the surgeries were performed by dissection method. Haemostasis during the procedure was secured by either ligation with silk 1 or using diathermy. The results were analyzed using SPSS 16.0 for windows. Results: A total of180 cases were included in the study. The ages of the patients ranged from 5 to 40 years with the mean age of 15.56 years and a std.deviation of +/- 8.24. The male to female ratio was 1.25:1. The number of hemorrhages occurring was greater in the ‘diathermy coagulation’ group as compared to the ‘silk ligation’ group. However, the observed difference was statistically insignificant (p >.05). Conclusion: Primary haemorrhage occurring during tonsillectomy is a serious threat and control of bleeding during the procedure should therefore be meticulous. Both suture ligation and coagulation diathermy for control of bleeders during the procedure by dissection method are equally effective. PMID:26430438

    International and national organizations have formulated guidelines establishing limits for occupational and residential electromagnetic field (EMF) exposure at high-frequency fields. Italian legislation fixed 20 V/m as a limit for public protection from exposure to EMFs in the frequency range 0.1 MHz-3 GHz and 6 V/m as a reference level. Recently, the law was changed and the reference level must now be evaluated as the 24-hour average value, instead of the previous highest 6 minutes in a day. The law refers to a technical guide (CEI 211-7/E published in 2013) for the extrapolation techniques that public authorities have to use when assessing exposure for compliance with limits. In this work, we present measurements carried out with a vectorial spectrum analyzer to identify technical critical aspects in these extrapolation techniques, when applied to UMTS and LTE signals. We focused also on finding a good balance between statistically significant values and logistic managements in control activity, as the signal trend in situ is not known. Measurements were repeated several times over several months and for different mobile companies. The outcome presented in this article allowed us to evaluate the reliability of the extrapolation results obtained and to have a starting point for defining operating procedures.

    Objective To evaluate the effectiveness of the newly developed food pictures in improving the accuracy of 24 h dietary recall survey. Method Forty inpatients were selected to study the accuracy of recall method in dietary survey with or without illustrative food pictares as compared with the weighing method. The data of food consumption and nutrients intakes were collected for comparison. Results Compared with weighing method, besides egg and beef, all the foods and nutrients were underestimated by 24 h dietary recall method without pictures. The data of fat, vitamin E, sodium, calcium and dietary fiber intakes showed certain degree of positive correlation with those obtained by weighing method, but not correlated in other nutrients and food intakes. The data of foods and nutrients intakes obtained by pictures-assisted 24 h dietary recall method were highly correlated with those obtained by weighing method. Conclusion The newly developed food pictures can improve the accuracy of 24 h dietary recall method. It is easy to carry and use, especially in field work and deserves wider application.

    Raised blood pressure is a leading cause of morbidity and mortality worldwide; improved nutritional approaches to population-wide prevention are required. Few data are available on dietary phosphorus and blood pressure and none are available on possible combined effects of phosphorus, magnesium, and calcium on blood pressure. The International Study of Macro- and Micro-Nutrients and Blood Pressure is a cross-sectional epidemiologic study of 4680 men and women ages 40 to 59 from 17 population samples in Japan, China, United Kingdom, and United States. Blood pressure was measured 8 times at 4 visits. Dietary intakes were obtained from four 24-hour recalls plus data on supplement use. Dietary phosphorus was inversely associated with blood pressure in a series of predefined multiple regression models, with the successive addition of potential confounders, both nondietary and dietary. Estimated blood pressure differences per 232 mg/1000 kcal (2 SD) of higher dietary phosphorus were -1.1 to -2.3 mm Hg systolic/-0.6 to -1.5 mm Hg diastolic (n=4680) and -1.6 to -3.5 mm Hg systolic/-0.8 to -1.8 mm Hg diastolic for 2238 "nonintervened" individuals, ie, those without special diet/nutritional supplements or diagnosis/treatment for cardiovascular disease or diabetes. Dietary calcium and magnesium, correlated with phosphorus (partial r=0.71 and r=0.68), were inversely associated with blood pressure. Blood pressures were lower by 1.9 to 4.2 mm Hg systolic/1.2 to 2.4 mm Hg diastolic for people with intakes above versus below country-specific medians for all 3 of the minerals. These results indicate the potential for increased phosphorus/mineral intake to lower blood pressure as part of the recommendations for healthier eating patterns for the prevention and control of prehypertension and hypertension.

    In Brazil, there is neither a register of the use of sulphites by the food industry nor is research being undertaken on their dietary exposure to the population. The objective of the work reported here was to estimate the dietary exposure to sulphites in two different groups of high school students, a fee-paying school group and a state school group. The data were collected through a 24-hour dietary recall, which provided estimates of sulphited foods and beverages in the diet. The Maximum Permitted Level (MPL), established by the Brazilian legislation for each of the sulphited food and beverages, was used to measure the dietary exposure to this additive. On this basis none of the students could have exceeded the Acceptable Daily Intake (ADI) of 0.70 mg SO2/kg bw/day, with a average dietary exposure of 0.07 mg SO2/kg bw/day (p<0.001), with no significant statistical difference (p=0.643) between fee-paying and state school students. Highly exposed consumers (dietary exposure to more than 50% of the ADI, or either, 0.35 mg SO2/kg bw/day, to the maximum of 0.52 mg SO2/kg bw/dia) represented 4.5% of the researched samples and reached these levels of intake due to a consumption beyond 500 ml/day of industrialized packaged fruit juices, and, in the fee-paying school, for associating its consumption with alcoholic beverages like beer and wine.

    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.

    Full Text Available Background Urban traffic accidents are an extensively significant problem in small and busy towns in Iran. This study tried to explore the epidemiological pattern of urban traffic accidents in Kashan and Aran-Bidgol cities, Iran. Objectives This study aimed to assess various epidemiological factors affecting victims of trauma admitted to a main trauma center in Iran. Patients and Methods During a retrospective study, data including age, sex, injury type and pattern, outcome, hospital stay and treatment expenditures regarding urban Road Traffic Accidents (RTAs for one year (March 2012-March 2013 were obtained from the registry of trauma research center, emergency medical services and deputy of health of Kashan University of Medical Sciences. One-way ANOVA and chi-square tests were used to analyze data using SPSS version 16.0. P value < 0.05 was considered significant. Results A total of 1723 victims (82.6% male, sex ratio of almost 5:1 were considered in this study. Mortality rate in trauma cases hospitalized more than 24 hours during our study was 0.8%. Young motorcyclist men with the rate of more than 103 per 10000 were the most vulnerable group. The most common injury was head injury (73.6% followed by lower limb injury (33.2%. A significant association was found between mechanism of injury and head, lower limb, multiple injuries and high risk age group. Conclusions Urban RTAs are one of the most important problems in Kashan and Aran-Bidgol cities, which impose a great economic burden on health system. Motorcyclists are the most vulnerable victims and multiple trauma and head injury are seen among them extensively.

    Hourly rainfall measurements of 1919 national-level meteorological stations from 1981 through 2012 are used to document, for the first time, the climatology of extreme rainfall in hourly through 24-h accumulation periods in China. Rainfall amounts for 3-, 6-, 12- and 24-h periods at each station are constructed through running accumulation from hourly rainfall data that have been screened by proper quality control procedures. For each station and for each accumulation period, the historical maximum is found, and the corresponding 50-year return values are estimated using generalized extreme value theory. Based on the percentiles of the two types of extreme rainfall values among all the stations, standard thresholds separating Grade I, Grade II and Grade III extreme rainfall are established, which roughly correspond to the 70th and 90th percentiles for each of the accumulation periods. The spatial characteristics of the two types of extreme rainfall are then examined for different accumulation periods. The spatial distributions of extreme rainfall in hourly through 6-h periods are more similar than those of 12- and 24-h periods. Grade III rainfall is mostly found over South China, the western Sichuan Basin, along the southern and eastern coastlines, and in the large river basins and plains. There are similar numbers of stations with Grade III extreme hourly rainfall north and south of 30°N, but the percentage increases to about 70% south of 30°N as the accumulation period increases to 24 hours, reflecting richer moisture and more prolonged rain events in southern China. Potential applications of the extreme rainfall climatology and classification standards are suggested at the end.

    Eighty-three patients with Graves' disease had been treated with methylmercaptoimidazole (MMI). They were prescribed a maintenance dose of antithyroid drug (MMI, 5 mg/day) at the time of a T{sub 3} suppression test. The 3-hour and 24-hour thyroidal {sup 123}I uptake after T{sub 3} administration (75 {mu}g/day, 2 weeks) were measured (post T{sub 3} uptake). In 38 patients whose post T{sub 3} uptake was below 35% in post T{sub 3} 24-hour uptake, treatment was stopped. The T{sub 3} suppression test was then repeated 1 and 3 months later. During a one-year follow up, 26 remained well, while 12 relapsed within 6 to 12 months. We have observed a good correlation between 3-hour uptake and 24-hour uptake of {sup 123}I after T{sub 3} administration (r=0.847, p<0.001). In 38 patients who showed positive T{sub 3} suppression, most patients with MMI withdrawal produced a marked overshoot of post T{sub 3} 3-hour and 24-hour uptake at one month. Retrospective analysis indicated that there was no significant difference in circulating thyroid hormone levels between remission and relapse groups. The present study provides evidence that 3-hour uptake values are able to be substituted for 24-hour uptake values during a T{sub 3} suppression test. In addition, overshoot of thyroidal uptake after antithyroid drug withdrawal was observed in 3-hour values, similar to 24-hour values. (author).

    Reverse redistribution is frequently observed after revascularization in acute myocardial infarction, and usually regarded as a predictor of viable myocardium on stress/rest and 2- to 4-hour redistribution {sup 201}Tl SPECT. However, there is not enough report of reverse redistribution in case of 24-hour delayed SPECT, which is commonly used for viability assessment. In this report, a case of reverse redistribution on rest and 24-hour delayed {sup 201}Tl SPECT is reported with use of automatic segmental quantitative analysis. The myocardium of reverse redistribution was dysfunctional on gated SPECT, and diagnosed as non-viable on {sup 18}F-FDG PET.

    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.

    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.

    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.

    Full Text Available Background: Polycystic ovary syndrome (PCOS is the most common endocrinopathy in women. It may involve an impairment in physiologic regulation of leptin and ghrelin. There is limited, controversial data on the relation of dietary components with leptin and ghrelin in PCOS, so the current study has been conducted to explore the effects of different macronutrients on serum levels of leptin and ghrelin in PCOS and healthy subjects. Materials and Methods: In this case-control study, we randomly choose 30 PCOS patients and 30 healthy age and body mass index (BMI matched controls. Intake of macronutrients [protein, total fat, saturated, monounsaturated and polyunsaturated fatty acids (PUFA, carbohydrate, dietary fiber] and energy were assessed using 3-day, 24-hour food recall and food frequency questionnaires (FFQ. Fasting hormonal status was measured for each participant. Results: PCOS women had higher levels of serum leptin, insulin, testosterone, and luteinizing hormone (LH, whereas sex hormone-binding globulin (SHBG was lower compared to healthy women. There was no significant difference in mean ghrelin concentrations between the groups. Among PCOS women, independent of BMI and total energy intake, we observed an inverse association between leptin concentration and total dietary fat (β=-0.16, P<0.05 and saturated fatty acid (SFA intake (β=-0.58, P<0.05. This relationship was not seen in the healthy subjects. There was no significant association between ghrelin and macronutrients in PCOS and healthy participants. Conclusion: Certain habitual dietary components such as fat and SFA may decrease serum leptin, whereas ghrelin is not influenced by these in PCOS women. More studies are needed to better clarify the effects of dietary macronutrients on serum leptin and ghrelin.

    Refugees in the United States have higher rates of some chronic diseases than US-born residents or other first-generation immigrants. This may be partially a result of dietary practices in the United States. There is limited information about which factors are related to dietary practices in refugee populations, particularly those who have been in the United States for 10 to 20 years. Research with Cambodian communities may be useful for examining the relationship between refugee characteristics and dietary practices. Two focus groups (n=11) and a survey (n=150) of Cambodian refugee women were conducted in Lowell, MA, from 2007 to 2008. χ(2) analyses, t tests, and analysis of variance tests were used to describe differences in dietary practices (24-hour recall and a targeted qualitative food assessment) by group characteristics. Higher acculturation was related to higher likelihood of eating brown rice/whole grains, and to lower likelihood of eating high-sodium Asian sauces. Higher education was related to higher likelihood of eating vegetables and fruits and to eating white rice fewer times. Nutrition education and receiving dietary advice from a health care provider were related to higher likelihood of eating whole grains/brown rice. Having a child at home was related to a higher likelihood of eating fast food. Among Cambodian refugees who have been in the United States for 10 to 20 years, dietary practices appear to have a relationship with acculturation (positive association), the interrupted education common to refugees (negative association), nutrition education from either programs or health care providers (positive association), and having a child at home (negative association).

    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.

    The aim of this study was to investigate the associations between caries experience and daily intake of calcium (Ca), phosphorus (P), magnesium (Mg), and Ca/P ratio. A total of 2248 schoolchildren were recruited based on a population-based survey. Each participant received a dental examination and questionnaire interviews about the 24-hour dietary recalls and food frequency. The daily intake of Ca, P, Mg, and Ca/P ratio were inversely associated with primary caries index, but only the Ca/P ratio remained significant after adjusting for potential confounders. According to the Taiwanese Dietary Reference Intakes, the Ca/P ratio was related to both caries in primary teeth (odds ratio = 0.52, p = 0.02) and in permanent teeth (odds ratio = 0.59, p = 0.02). The daily intakes of Ca/P ratio remained an important factor for caries after considering potential confounding factors.

    Full Text Available Objective. To assess the reproducibility and validity of a 116 item semi-quantitative food frequency questionnaire (FFQ, designed to assess the relation between dietary intake and chronic diseases. Material and methods. To test the reproducibility of the FFQ questionnaire, the FFQ was administered twice to 134 women residing in Mexico City at an interval of approximately one year; to assess the validity we compared results obtained by the FFQs with those obtained by four 4-day 24-hour recalls at three month intervals. Validity and reproducibility were evaluated using regression analysis and Pearson and intraclass correlation coefficients of log-e and calorie-adjusted nutrient scores. Results. Mean values for intake of most nutrients assessed by the two food frequency questionnaires were similar. However, means for the 24-hr recall were significantly lower. Intraclass correlation coefficients for nutrient intakes, assessed by questionnaires, administered one year apart, ranged from 0.38 for cholesterol to 0.54 for crude fiber. Correlation coefficients between energy-adjusted nutrient intakes, measured by diet recalls, and the first FFQ ranged from 0.12 for polyunsaturated fatty acids to 0.67 for saturated fatty acids. Regression coefficients between 24-hr recall and FFQ,s were all significant were significant for all nutrients, except for polyunsaturated fat, folic acid, vitamin E and Zinc. Conclusions. These data indicate that this semi-quantitative FFQ is reproducible and provides a useful estimate by which to categorize individuals by level of past nutrient intake. However, its application outside Mexico City or in different age and gender populations will require additional modifications and validation efforts.

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

    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.

    Full Text Available Background & Objectives: There are limited number of studies conducted on the correlation between Glycemic index and Glycemic load of a food program and metabolic factors such as blood lipids in Asian countries including Iran. Therefore, this study aimed at analyzing the correlation between Glycemic index and Glycemic load of Iranian food program and blood lipids. Materials & Methods: The subjects were 95 women working in Ahvaz University of Medical Sciences in the range of 20 to 55 years old. Glycemic index and Glycemic load of the food program was analyzed with 24-hour food recall questionnaires (4-6 recall. For calculating GI and GL, Iranian food GI tables, and also, international GI and GL table were used. The levels of blood lipids including HDL cholesterol, total cholesterol, and triglycerides of the blood were measured and the level of LDL Cholesterol was calculated using Friedewald formula. Also, Anthropometric measurements were done using standard methods. Resulst: The mean age of subjects in this study was 36 years. GI mean was 72.1 and GL mean was 153.2. In this study, there was no significant relation between HDL cholesterol, LDL cholesterol, total cholesterol and Blood TG with Glycemic index and Glycemic load of food program. Conclusion: Unlike findings of west and Asian countries, both dietary GI and GL were not correlated with metabolic factors including blood lipid levels in this study , underreporting of individuals may influence the results of the study.

    Background: Studies have demonstrated the effect of different dietary fats on blood pressure (BP) in general population. However, these associations have not yet been described in people with spinal cord injury (SCI). Methods: Referred patients to Brain and SCI Research Center between 2011 and 2014 have been invited to participate. Only paraplegic individuals were recruited and patients with injury at cervical or higher thoracic sections were excluded to omit the bias effect of autonomic dysreflexia. Dietary intakes were assessed by recording consumed foods by 24-hour dietary recall interviews using Nutritionist IV 3.5.3 modified for Iranian foods. Systolic BP (SBP) and diastolic BP (DBP) were measured 3 times and the mean values entered analysis. Results: Higher intakes of cholesterol were related to higher BP (P = 0.010 and 0.011 for SBP and DBP, respectively). Similarly, intake of saturated fat was positively correlated to both SBP (P = 0.016, r = 0.21) and DBP (P = 0.011, r = 0.22). The effect of eicosapentaenoic acid (EPA) on BP was insignificant (P = 0.760 and 0.720 for SBP and DBP, respectively). However, intake of docosahexaenoic acid (DHA) was related to lower BP among people with SCI. Conclusion: This study has demonstrated that higher intakes of cholesterol and saturated fat are associated with increased BP, whereas DHA is an antihypertensive agent. Dietary modifications with reduction of cholesterol and saturated fat along with intake of additional DHA supplements may help to reduce BP in spinal cord injured-individuals with hypertension.

    Immigrants comprise a noteworthy segment of the European population whose numbers are increasing. Research on the dietary habits of immigrants is critical for correctly providing diet counselling and implementing effective interventions. The aim of the present study was to identify the presently used methods and adaptations required for measuring dietary intake in European immigrant groups. A comprehensive review strategy included a structured MEDLINE search, related references and key expert consultations. The review targeted adults from non-European union (European union-15 countries) ethnic groups having the largest populations in Europe. As studies evaluating nutrient intake were scarce, papers evaluating intake at the level of foods were included. Forty-six papers were selected. Although Eastern Europe, Turkey, Africa (North, Sub-Saharan and Afro-Caribbean), Asia and Latin America represented the most numerous immigrant groups, papers on dietary intake were not available for all populations. Interview-administered FFQ and repeated 24 hour recalls were the most frequently applied instruments. Inclusion of ethnic foods and quantification of specific portion sizes of traditional foods and dishes in assessment tools as well as food composition databases were commonly identified problems. For FFQ, food list elaboration required particular consideration to reflect key ethnic foods and relative contribution to nutrient intake. Extra efforts were observed to overcome cultural barriers to study participation. Evaluating dietary intake of immigrant populations requires special attention to various methodological aspects (sampling, recruiting, instruments used, method of administration, food composition database, acculturation, etc.) so as to adequately address the range of socio-cultural factors inherent in these nutritionally at risk target groups.

  5. Dietary pattern of Finnish children with low high caries experience.

    Kleemola-Kujala, E; Räsänen, L

    1979-08-01

    The correlations between dietary patterns and caries were studied in a series consisting of 534, 5-, 9- and 13-year-old Finnish rural children from low-fluoride areas (0.10-0.46 parts/10(6)). The food consumption of the children was assessed by the 24-hour recall method. The consumption of sweets was estimated by the dietary history method. Caries was diagnosed by clinical inspection. Children with a low and children with a high caries experience were compared with regard to food and nutrient intakes per 1000 kcal. The intakes of most foods and nutrients were similar in the low-caries and in the high-caries groups. However, the diet of the high-caries groups of 5- and 13-year-olds contained less iron, thiamine and ascorbic acid than the diet of the low-caries groups. The intake of sugar and sugar-containing products per unit of energy was higher in the high-caries groups. This was true for soft drinks in particular. Among the 9-year-olds the proportion of sugar consumed as such was greater in the high-caries than in the low-caries children. With regard to the total monthly consumption of sweets no significant differences were observed between the high- and low-caries groups. Analysis of the energy-standardized consumption of food and nutrients thus showed that the relative proportion of sugar and sugar-containing products was somewhat greater in the diet of the high-caries children than in the diet of the low-caries children, but not as high as could be expected. These products replaced foods with a higher nutritive value with the result that the diet of the high-caries groups was on the whole more refined than the diet of the low-caries groups.

    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).

    OBJECTIVE: To determine if obesity and dietary quality in low-income children differed by participation in the Supplemental Nutrition Assistance Program (SNAP), formerly the Food Stamp Program. METHODS: The study population included 5193 children aged 4 to 19 with household incomes ≤130% of the federal poverty level from the 1999–2008 NHANES. Diet was measured by using 24-hour recalls. RESULTS: Among low-income US children, 28% resided in households currently receiving SNAP benefits. After adjusting for sociodemographic differences, SNAP participation was not associated with a higher rate of childhood obesity (odds ratio = 1.11, 95% confidence interval [CI]: 0.71–1.74). Both SNAP participants and low-income nonparticipants were below national recommendations for whole grains, fruits, vegetables, fish, and potassium, while exceeding recommended limits for processed meat, sugar-sweetened beverages, saturated fat, and sodium. Zero percent of low-income children met at least 7 of 10 dietary recommendations. After multivariate adjustment, compared with nonparticipants, SNAP participants consumed 43% more sugar-sweetened beverages (95% CI: 8%–89%), 47% more high-fat dairy (95% CI: 7%, 101%), and 44% more processed meats (95% CI: 9%–91%), but 19% fewer nuts, seeds, and legumes (95% CI: –35% to 0%). In part due to these differences, intakes of calcium, iron, and folate were significantly higher among SNAP participants. Significant differences by SNAP participation were not evident in total energy, macronutrients, Healthy Eating Index 2005 scores, or Alternate Healthy Eating Index scores. CONCLUSIONS: The diets of low-income children are far from meeting national dietary recommendations. Policy changes should be considered to restructure SNAP to improve children’s health.

    This study examined dietary patterns of adults on Guam. Four hundred subjects were selected via a multistage procedure to represent the island's population. A 24-hour dietary recall was administered via telephone in 1995 to 1996. Diets were computer analyzed. There were 4,913 food items reported, representing 1,042 individual foods. Most respondents, 51.3%, had a "more-frequent" eating pattern, 36.9% had "regular" and 11.8% had "less-frequent." Energy consumption increased (p<0.05) with eating frequency. Highest levels of all nutrients (p<0.05) were at the evening meal. The sexes did not differ in nutrient proportions by meal. Grains, meats, and beverages were eaten most frequently. Meat/fish, mixed dishes, and grains supplied 68% of the energy and 47% to 91% of the micronutrients. Twenty five percent of the carbohydrate was from sweetened drinks and desserts. Rice was the most frequently consumed food. More than half of the subjects had no fruit, a third had no vegetables, and only 38.5% had dairy foods. Calcium came from multiple sources: dairy (27.6%), mixed dishes (23.8%), fish (12.6%), desserts (8.5%) and vegetables (6.6%). Most people, 91.8%, had fiesta meals with median consumption at 6 meals per year (range: 0 to 200). Betel nut was used by 12.3% of the sample with median consumption 0 whole nuts per day (range: 0 to 25). Ethnic differences (p<0.01) were observed in both fiesta meal and betel nut consumption. The Guamanian diet includes limited use of traditional foods and dietary patterns associated with increased risk for chronic disease.

    Full Text Available BackgroundThe hepatitis C virus is one of the main causes of liver disease worldwide and may develop nutritional deficiencies.ObjectiveThe objective of this study was to assess and compare different nutritional status methods of adult patients with chronic hepatitis C virus, and to describe inadequacies in dietary intake.MethodsA cross-sectional study was conducted with adult outpatients with hepatitis C virus at a Brazilian hospital. Nutritional assessment included the 24-hour dietary recall, anthropometry (body weight, height, body mass index, triceps skinfold, mid-upper arm circumference, mid-arm muscle circumference, mid-upper arm muscle area, adductor policis muscle, Subjective Global Assessment, Royal Free Hospital Global Assessment and handgrip strength.ResultsA total of 94 outpatients (ages 30 to 76 years, was included, 46 were men. The prevalence of malnutrition as measured by the different methods was 6.4% (body mass index; 60.6% (handgrip strength, and 53.2% (Royal Free Hospital Global Assessment. There was correlation between mid-upper arm circumference and mid-arm muscle circumference (r=0.821, mid-upper arm circumference and triceps skinfold (r=0.575 and mid-upper arm circumference and mid-upper arm muscle area (r=0.781. Energy and protein intakes were below recommended levels in 49 (52.1% and 44 (46.8% of patients, respectively. Inadequate calcium, potassium, zinc and vitamin C intakes occurred in 92.6%, 97.9%, 63.8% and 60.6% of patients. There was an association between dietary energy and protein intake with Royal Free Hospital Global Assessment (P<0.001 and a tendency for them to be associated with handgrip strength (P=0.076 and P=0.054.ConclusionMalnutrition is frequently in hepatitis C virus patients. They have high prevalence of inadequate energy, protein and micronutrients intake, even in the absence of cirrhosis.

    Full Text Available Background: Studies have demonstrated the effect of different dietary fats on blood pressure (BP in general population. However, these associations have not yet been described in people with spinal cord injury (SCI.Methods: Referred patients to Brain and SCI Research Center between 2011 and 2014 have been invited to participate. Only paraplegic individuals were recruited and patients with injury at cervical or higher thoracic sections were excluded to omit the bias effect of autonomic dysreflexia. Dietary intakes were assessed by recording consumed foods by 24-hour dietary recall interviews using Nutritionist IV 3.5.3 modified for Iranian foods. Systolic BP (SBP and diastolic BP (DBP were measured 3 times and the mean values entered analysis.Results: Higher intakes of cholesterol were related to higher BP (P = 0.010 and 0.011 for SBP and DBP, respectively. Similarly, intake of saturated fat was positively correlated to both SBP (P = 0.016, r = 0.21 and DBP (P = 0.011, r = 0.22. The effect of eicosapentaenoic acid (EPA on BP was insignificant (P = 0.760 and 0.720 for SBP and DBP, respectively. However, intake of docosahexaenoic acid (DHA was related to lower BP among people with SCI.Conclusion: This study has demonstrated that higher intakes of cholesterol and saturated fat are associated with increased BP, whereas DHA is an antihypertensive agent. Dietary modifications with reduction of cholesterol and saturated fat along with intake of additional DHA supplements may help to reduce BP in spinal cord injured-individuals with hypertension.

    Dietary intake is a modifiable behavior that may reduce the risk of recurrence and death among breast cancer survivors. Cancer survivors are encouraged to consume a diet rich in fruit, vegetables, and whole grains and limit red meat, processed meat, and alcohol intake. Using data from the National Health and Nutrition Examination Survey (2003-2006), this study examined whether breast cancer survivors and women with no history of cancer differed in the distribution of usual intake of foods included in the dietary recommendations for preventing cancer and recurrences. Participants completed one or two 24-hour dietary recalls. The food groups included in this analysis were whole fruit; total vegetables; dark green and orange vegetables; whole grains; red meat; processed meat; alcohol; and calories from solid fat, alcohol, and added sugar. The National Cancer Institute Method was used to estimate the distribution of usual intake and to compare breast cancer survivors (n=102) to noncancer respondents (n=2,684). Using age and cancer survivor as covariates, subgroup estimates of usual intake were constructed. No significant group differences were found, except that survivors reported a greater intake of whole grains. More than 90% of both groups did not meet recommendations for fruits, vegetables, and whole grains; 75.4% and 70.2%, respectively, consumed less than the red meat recommendation; and cancer survivors was not significantly different from women with no history of cancer.

A hipótese foi de que limiar de sensibilidade gustativa ao sal (LSGS aumentado se associasse a maior natriúria em 24 horas e níveis aumentados de PA. MÉTODOS: Foram avaliados 24 voluntários sem diagnóstico de HA. Para avaliar LSGS, usou-se soluções de cloreto de sódio (NaCl em diferentes concentrações. Os voluntários foram submetidos à monitorização ambulatorial da pressão arterial (MAPA de 24 horas e coleta de urina de 24 horas para dosagem de sódio (NaU. Para análise, foram agrupados de acordo com o LSGS, aumentado ou normal. RESULTADOS: Os grupos não diferiram para idade, índice de massa corporal (IMC, variáveis demográficas, uso de álcool, fumo e PA. NaU foi significativamente maior no grupo com LSGS aumentado. Utilizando-se o coeficiente de correlação de Pearson, com significância determinada pelo teste t, houve correlação de forte intensidade entre médias de PA sistólica e diastólica com IMC, de regular intensidade entre LSGS e NaU, assim como para PA sistólica e NaU. CONCLUSÃO: Natriúria de 24 horas foi maior em indivíduos com LSGS aumentado, sugerindo que esta maior avidez ao sal determine maior ingestão de sódio. Houve forte associação entre PA e IMC. Não foi evidenciada associação entre LSGS e PA, diferente do já documentado em pacientes com PA aumentada.

    Full Text Available A few studies have performed to evaluate the temperature variation influences over on the stroke rates in Brazil. METHOD: 176 medical records of inpatients were analyzed after having had a stroke between 2004 and 2006 at Hospital Israelita Albert Einstein. The temperature preceding the occurrence of the symptoms was recorded, as well as the temperature 6, 12 and 24 hours before the symptoms in 6 different weather substations, closest to their houses in São Paulo. RESULTS: Strokes occurred more frequently after a variation of 3ºC between 6 and 24 hours before the symptoms. There were most hospitalizations between 23-24ºC. CONCLUSION: Incidence of stroke on these patients was increased after a variation of 3º Celsius within 24 hours before the ictus. The temperature variations could be an important factor in the occurrence of strokes in this population.Poucos trabalhos têm estudado a variação sazonal e de temperatura em acidente vascular cerebral (AVC no Brasil.

    The primary aim of the study was to estimate the consumption of polyphenols in a population of 6661 subjects aged between 20 and 74 years representing a cross-section of the Polish society, and the second objective was to compare the intakes of flavonoids calculated on the basis of the two commonly used databases. Daily food consumption data were collected in 2003-2005 using a single 24-hour dietary recall. Intake of total polyphenols was estimated using an online Phenol-Explorer database, and flavonoid intake was determined using following data sources: the United States Department of Agriculture (USDA) database combined of flavonoid and isoflavone databases, and the Phenol-Explorer database. Total polyphenol intake, which was calculated with the Phenol-Explorer database, was 989 mg/day with the major contributions of phenolic acids 556 mg/day and flavonoids 403.5 mg/day. The flavonoid intake calculated on the basis of the USDA databases was 525 mg/day. This study found that tea is the primary source of polyphenols and flavonoids for the studied population, including mainly flavanols, while coffee is the most important contributor of phenolic acids, mostly hydroxycinnamic acids. Our study also demonstrated that flavonoid intakes estimated according to various databases may substantially differ. Further work should be undertaken to expand polyphenol databases to better reflect their food contents.

    Uremic pruritus (UP) is a common and incapacitating symptom in patients undergoing hemodialysis (HD). The pathogenesis of UP is multifactorial and complex. Particulate matter (PM), a major air pollutant, is a mixture of particles with various chemical compositions. PM is associated with several allergic diseases, including dermatitis. To assess the role of PM (PM with a diameter of <10 μm [PM10] and PM with a diameter of <2.5 μm [PM2.5]) and other clinical variables in UP in patients on HD, we recruited 866 patients on maintenance HD (MHD). We analyzed the number of days of mean 24-hour PM10 ≥125 μg/m3/12 months (NDPM10) or the number of days of mean 24-hour PM2.5 ≥35 μg/m3/12 months (NDPM2.5) exceeding the standard level in the past 12 months respectively to determine the association with UP. In a multivariate logistic regression, HD duration, serum ferritin levels, low-density lipoprotein (LDL) levels, and NDPM2.5 ≥116 days/12 months were positively associated with UP. This cross-sectional study showed that the number of days on which the environmental PM2.5 exceeds the standard level might be associated with UP in patients on MHD. PMID:28260912

    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.

  12. Recalled emotions and risk judgments

    Full Text Available The current study is based on a field study of the 2006 Israel-Lebanon war that was conducted in two waves, the first two weeks after the end of the war, and the second 18 months later (2008. 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 Abstract Background Several studies have demonstrated the efficacy of artemisinin-combination therapy (ACT across malaria zones of the world. Fixed dose ACT with shorter courses and fewer tablets may be key determinants to ease of administration and compliance. Methods Children aged one year to 13 years presenting with uncomplicated Plasmodium falciparum malaria were recruited in Ibadan, south-western Nigeria. A total of 250 children each were randomly assigned to receive three doses of artesunate/sulphamethoxypyrazine/pyrimethamine (AS + SMP (12 hourly doses over 24 hours or three doses of artesunate/amodiaquine (AS + AQ (daily doses over 48 hours. Efficacy and safety of the two drugs were assessed using a 28-day follow-up and the primary outcome was PCR- corrected parasitological cure rate and clinical response. Results There were two (0.4% early treatment failures, one in each treatment arm. The PCR corrected cure rates for day 28 was 97.9% in the AS + AQ arm and 95.6% in the AS + SMP arm (p = 0.15. The re-infection rate was 1.7% in the AS + AQ arm and 5.7% in the AS + SMP arm (p = 0.021. The fever clearance time was similar in the two treatment groups: 1 - 2 days for both AS + SMP and AS + AQ (p = 0.271. The parasite clearance time was also similar in the two treatment groups with 1 - 7 days for AS + SMP and 1 - 4 days for AS + AQ (p = 0.941. The proportion of children with gametocytes over the follow-up period was similar in both treatment groups. Serious Adverse Events were not reported in any of the patients and in all children, laboratory values (packed cell volume, liver enzymes, bilirubin remained within normal levels during the follow-up period but the packed cell volume was significantly lower in the AS + SMP group. Conclusions This study demonstrates that AS + SMP FDC given as three doses over 24 hours (12-hour intervals has similar efficacy as AS + AQ FDC given as three doses over 48 hours (24-hour interval for the treatment of

    Introduction Poor dietary intake during pregnancy can have negative repercussions on the mother and fetus. This study therefore aims to explore the dietary diversity (DD) of pregnant women and its associations with pregnancy outcomes among women in Northern Ghana. The main outcome variables to be measured are gestational weight gain and birth weight. Methods and analysis A prospective cohort study design will be used and 600 pregnant women in their first trimester will be systematically recruited at health facilities and followed until delivery. In three follow-up visits after recruitment, information on sociodemographic and general characteristics, physical activity (International Physical Activity Questionnaire (IPAQ) short form, dietary intake (24-hour food recall), anthropometry and pregnancy outcomes will be collected. DD will be measured three times using the minimum DD-women (MDD-W) indicator and the mean of the three values overall will be used to determine low (<5 food groups) and high (≥5 food groups) DD. Data will be analysed using SPSS. Comparisons between groups (categorical data) will be made using the χ2 test for proportions, and t-tests and ANOVA will be performed on continuous variables. Regression analysis will be used to identify independent outcome predictors while controlling for possible confounding factors. The results may help to identify differences in DD between healthy and unhealthy pregnancy outcomes. Ethics and dissemination The study protocol has been approved by the ethics committee of Tehran University of Medical Sciences and the ethical review committee of the Tamale Teaching Hospital. Written informed consent will be obtained from all subjects. The results will be published in due course. PMID:27655259

  15. Tulimbe Nutrition Project: a community-based dietary intervention to combat micronutrient malnutrition in rural southern Malawi.

    This article describes the community-based nutrition intervention in rural southern Malawi. The program aims to reverse micronutrient deficiencies in vitamin A, iron, and zinc in a society where staple diets are plant-based and contain high levels of anti-nutrients. Anti-nutrients, such as polyphenols, dietary fiber, and phytates, inhibit absorption of iron and zinc. This population's diet was also low in dairy and meat products. The Tulimbe Nutrition Project aimed to modify and diversify diets rather than to supplement or fortify diets. This approach was more culturally acceptable and economically feasible. The approach required changing food selection patterns and methods of preparing and processing indigenous foods. The new diets aimed to enhance the availability, access, and use of micronutrient-rich foods throughout the year. The project was initiated in 1995 in two communities among 300 families with children ranging in age from 3 to 7 years. A baseline assessment with interviews and focus groups was conducted. The assessment for children included a 24-hour dietary recall, anthropometric measurement, and other clinical measurement. Anthropometric and dietary assessments were repeated at 6 and 12 months. New cultivars and technologies were introduced, such as soybeans, short-duration pigeon peas, groundnuts, sunflower seeds, and papaya seedlings. The Malawi Industrial Research and Technology Development Center built and installed solar dryers, seed oil presses, and ovens in each community. People were encouraged to include soaked and fermented maize flour and germinated cereal flours in infant and child porridges. Parents were educated about micronutrient-rich foods, meal frequencies, portion sizes, and food combinations. Information was provided through demonstrations, home visits, plays, songs, and booklets. The program evaluation is in progress.

    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.

    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. An increase in nutrition knowledge (β=-0.2, perceived responsibility (β=-0.3 and restriction (β=-0.3 from baseline to week 12 were associated with greater reduction in

    Full Text Available Abstract Background The extent of similarity between consolidation and reconsolidation is not yet fully understood. One of the differences noted is that not every brain region involved in consolidation exhibits reconsolidation. In trace fear conditioning, the hippocampus and the medial prefrontal cortex (mPFC are required for consolidation of long-term memory. We have previously demonstrated that trace fear memory is susceptible to infusion of the protein synthesis inhibitor anisomycin into the hippocampus following recall. In the present study, we examine whether protein synthesis inhibition in the mPFC following recall similarly results in the observation of reconsolidation of trace fear memory. Results Targeted intra-mPFC infusions of anisomycin or vehicle were performed immediately following recall of trace fear memory at 24 hours, or at 30 days, following training in a one-day or a two-day protocol. The present study demonstrates three key findings: 1 trace fear memory does not undergo protein synthesis dependent reconsolidation in the PFC, regardless of the intensity of the training, and 2 regardless of whether the memory is recent or remote, and 3 intra-mPFC inhibition of protein synthesis immediately following training impaired remote (30 days memory. Conclusion These results suggest that not all structures that participate in memory storage are involved in reconsolidation. Alternatively, certain types of memory-related information may reconsolidate, while other components of memory may not.

    Full Text Available Purpose: To evaluate whether medication counseling with emphasis on auxiliary labels improves recall of auxiliary label information and adherence to medication schedules. Methods: A prospective, randomized study of an educational intervention in community pharmacies near Baltimore, Maryland. Fifty literate, English-speaking adults receiving one of the 18 commonly dispensed antibiotics were randomized to receive a counseling session or no counseling. Five to seven days after medication pickup, a structured phone interview was conducted to capture data on recall of auxiliary labels and adherence. Results: A total of 39 subjects completed the phone interview (78%. The rate of correct recall was high: 77% correct recall for all three labels. Among those with incorrect recall, 7 out of 9 subjects received no counseling (p = 0.11. The auxiliary labels incorrectly recalled were all related to dietary restrictions. Conclusion: The findings from this study suggest that medication counseling emphasizing auxiliary label information may lead to improved recall and adherence to antibiotics. Additional studies are required to confirm the preliminary findings and determine whether they correspond to improved adherence. Information most commonly misunderstood were related to dietary restrictions. Additional research focusing on counseling related to dietary restrictions is recommended.

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

    Directory of Open Access Journals (Sweden)

    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

    1997-01-01

    The present study investigated the relationship between dream recall and sleep disorders. The sample comprised 762 patients who were diagnosed in the sleep laboratory. In the course of the examination they completed the sleep questionnaire SF-B (Görtelmeyer 1986). The results showed a heightened dream recall frequency (DRF) in insomniacs and patients with myoclonia. This result as well as the findings in the control group supports the arousal-retrieval model of dream recall (Koulack u. Goodenough 1976) which emphasizes the importance of nocturnal awakenings. However, this model seems only to be valid for males. In females, DRF is mainly influenced by emotional stress which is best explained by the salience hypothesis of Cohen and MacNeilage (1974). They pointed out that intensive dream emotions lead to high recallability of dream experience. The data gives evidence to the hypothesis of Ermann et al. (1993, 1994) which states that reduced DRF in terms of unsuccessful dream work is accompanied by frequent nocturnal awakenings. DRF of patients with sleep apnea syndrome did not differ from DRF in healthy controls. In addition, sleep apnea parameters did not correlate substantially with DRF. The finding that insomniacs reported more negatively toned dreams in comparison to persons who were examined for sleep apnea but did not showed a pathological apnea index. This may be an hint to increased emotional stress in this patient group. To summarize, the results are promising in clarifying the relationship between sleep disorders and dream life. The next step is to investigate dream reports of these patients by means of content analysis.

    In accordance with the international situation, the Chinese government has implemented the policy of 24 hours in the visa waiver program of exit-entry frontier inspection. In recent months, more and more new type cases of 24 hours in the visa waiver program of exit-entry frontier inspection have been discovered.

    Recall of food eaten at lunch decreases afternoon snack intake, suggesting that awareness of a recent eating episode may be an important factor influencing appetite. The aim of the present studies was to investigate whether the inhibitory effect of remembering a recent lunch meal on subsequent snack intake is dependent upon 1) the type and palatability of the snack offered; 2) participants' level of dietary restraint and tendency towards disinhibition; and 3) the delay between lunch and recall. Popcorn snacks differing in amount of added salt and rated palatability were offered to male participants in Experiment 1. Participants who recalled the lunch they had eaten that day consumed less of all types of popcorn than participants who recalled lunch eaten the previous day, suggesting that the effect of recent meal recall is not dependent upon the palatability of the snack food. In Experiment 2, a similar pattern of results was observed but only for women who scored low, and not high, on a measure of tendency toward dietary disinhibition, possibly because a tendency toward disinhibition is associated with impaired memory for the lunch. In Experiment 3, decreased cookie intake by women was observed after remembering today's lunch relative to a neutral control condition, but this effect was similarly only observed for participants scoring low in tendency toward disinhibition. In addition, the effect was dependent on the time elapsed between the lunch and recall, since intake was only reduced at a snack tasting session 3-hours post-lunch (when some forgetting of the meal occurred) and not 1-hour post-lunch. It is concluded that the inhibitory effect of recalling foods eaten at lunch on subsequent snack intake is a robust phenomenon that is related to memory of that lunch and is moderated by tendency toward dietary disinhibition.

    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.

    Introduction Poor diet habits and inadequate intake of nutrients are a concern in the elderly. Nutritional education with guidance may improve the results of the treatment of vertigo. Objective Evaluate the presence of benign paroxysmal positional vertigo (BPPV) associated with feeding habits. Methods Cross-sectional study with elderly people living independently. We evaluated nutritional habits through the method of dietary 24-hour recall and manipulation of Dix-Hallpike. Results Based on a sample of 487 individuals, 117 had BPPV. Among the 117 elderly patients with BPPV, 37 (31.62%) had inadequate feeding. From those 370 individuals without BPPV, 97 (26.21%) had inappropriate feeding. No significant association between nutritional habits and BPPV in the total population was observed (p = 0.3064). However, there was significant relation between BPPV and inadequate carbohydrate intake (p = 0.0419) and insufficient fiber intake (p = 0.03), and the diet of these subjects was rich in polyunsaturated fatty acids (p = 0.0084). Conclusion These data correlate with the dyslipidemia and hypertriglyceridemia status, making it extremely important to reduce the intake of fats and carbohydrates and increase the fiber intake to stabilize triglycerides and thus minimize harmful effects on the inner ear. Food readjustment is suggested in patients with BPPV, along with the work of a multidisciplinary team to improve the quality of the elderly. PMID:26491473

    Full Text Available Abstract Background According to the WHO report released in 2000, about 121 million people worldwide suffer from depression. The present study aimed to explore factors influencing depression in mothers from Rey, South of Tehran, Iran; who had elementary school children. Methods The cross-sectional survey was conducted in spring 2010. Four hundred thirty mothers who had elementary school children, were selected through a two stage cluster sampling. Beck Depression Inventory (BDI was used to assess depression in the mothers and a 24-hour food recall was used to collect information regarding their dietary intake. General information regarding economic condition and socio-economic status were also gathered using a questionnaire. The data was analyzed using chi-square, one-way analysis of variance and simple regression tests. Results In our study, 51.4% of the mothers suffered from depression. There was an inverse correlation between the educational level of the mothers and the heads of household, their occupational status, their marital status, their socio-economic condition and depression. Conversely, any increase in the family size worsened the depression. The daily intake of different macronutrients, except for fat, was lower in individuals of depressed group. Conclusion The present study emphasized the fact that more attention should be paid to the educational level and economic condition of the family in order to reduce maternal depression. Family size also plays an important role in this regard.

    Aim To examine the association of dietary fiber intake with inflammation and arterial stiffness among youth with type 1 diabetes (T1D) in the US. Methods Data are from youth ≥ 10 years old with clinically diagnosed T1D for ≥ 3 months and ≥ 1 positive diabetes autoantibody in the SEARCH for Diabetes in Youth Study. Fiber intake was assessed by food frequency questionnaire with measurement error (ME) accounted for by structural sub-models derived using additional 24-hour dietary recall data in a calibration sample and the respective exposure-disease model covariates. Markers of inflammation, measured at baseline, included IL-6 (n=1405), CRP (n=1387), and fibrinogen (n=1340); markers of arterial stiffness, measured approximately 19 months post-baseline, were available in a subset of participants and included augmentation index (n=180), pulse wave velocity (n=184), and brachial distensibility (n=177). Results Mean (SD) T1D duration was 47.9 (43.2) months; 12.5% of participants were obese. Mean (SD) ME-adjusted fiber intake was 15 (2.8) g/day. In multivariable analyses, fiber intake was not associated with inflammation or arterial stiffness. Conclusion Among youth with T1D, fiber intake does not meet recommendations and is not associated with measures of systemic inflammation or vascular stiffness. Further research is needed to evaluate whether fiber is associated with these outcomes in older individuals with T1D or among individuals with higher intakes than those observed in the present study.

    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

    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.

    Although speech and vocal music are consistently shown to impair serial recall for visually presented items, instrumental music does not always produce a significant disruption. This study investigated the features of instrumental music that would modulate the disruption in serial recall. 24 students were presented sequences of nine digits and required to recall the digits in order of presentation. Instrumental music as played either forward or backward during the task. Forward music caused significantly more disruption than did silence, whereas the reversed music did not. Some higher-order factor may be at work in the effect of background music on serial recall.

    There has been an increasing trend in the number of prescribed and over-the-counter drug recall over the last few years. The recall is usually due to company's discovery, customer's complaint or Food and Drug Administration (FDA) observation. The process of recall involves a planned specific course of action, which addresses the depth of recall, need for public warning, and the extent of effectiveness checks for the recall. The FDA review and/or recommend changes to the firm's recall strategy, as appropriate. The critical recall information list includes the identity of the product; summary of the failure; amount of product produced in the distribution chain and direct account. Product recalls clashes thousands of companies every year affecting: sales, testing customer relationships and disrupting supply chains. Drug recall is incubus for pharmaceutical companies. It effects the reputation of the company. The reason for the recall can be divided into two categories: manufacturing affined and safety/efficacy affined. It is essential to follow all the guidelines related to drug development and manufacturing procedure so as to minimize drug recall.

  13. Quantum bounce and cosmic recall

    CERN Document Server

    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 ...

    Sports nutrition professionals aim to influence nutrition knowledge, dietary intake and body composition to improve athletic performance. Understanding the interrelationships between these factors and how they vary across sports has the potential to facilitate better-informed and targeted sports nutrition practice. This observational study assessed body composition (DXA), dietary intake (multiple-pass 24-hour recall) and nutrition knowledge (two previously validated tools) of elite and sub-elite male players involved in two team-based sports; Australian football (AF) and soccer. Differences in, and relationships between, nutrition knowledge, dietary intake and body composition between elite AF, sub-elite AF and elite soccer players were assessed. A total of 66 (23 ± 4 years, 82.0 ± 9.2 kg, 184.7 ± 7.7 cm) players participated. Areas of weaknesses in nutrition knowledge are evident (57% mean score obtained) yet nutrition knowledge was not different between elite and sub-elite AF and soccer players (58%, 57% and 56%, respectively, p > 0.05). Dietary intake was not consistent with recommendations in some areas; carbohydrate intake was lower (4.6 ± 1.5 g/kg/day, 4.5 ± 1.2 g/kg/day and 2.9 ± 1.1 g/kg/day for elite and sub-elite AF and elite soccer players, respectively) and protein intake was higher (3.4 ± 1.1 g/kg/day, 2.1 ± 0.7 g/kg/day and 1.9 ± 0.5 g/kg/day for elite and sub-elite AF and elite soccer players, respectively) than recommendations. Nutrition knowledge was positively correlated with fat-free soft tissue mass (n = 66; r(2) = 0.051, p = 0.039). This insight into known modifiable factors may assist sports nutrition professionals to be more specific and targeted in their approach to supporting players to achieve enhanced performance.

    Objectives To (a) assess the association between dietary diversity (DD) score, socioeconomic status (SES) and maternal body mass index (BMI), and (b) the variation of the effects of DD and SES at different points of the conditional distribution of the BMI. Methods The study used Demographic and Health Surveys round 5 data sets from Ghana, Namibia and Sao Tome and Principe. The outcome variable for the analysis was maternal BMI. The DD score was computed using 24-hour dietary recall data. Quantile regression (QR) was used to examine the relationship between DD and SES, and maternal BMI, adjusting for other covariates. The QR allows the covariate effects to vary across the entire distribution of maternal BMI. Results Women who consumed an additional unit of DD achieved an increase of 0.245 in BMI for those in the 90th quantile in Ghana. The effect of household wealth increases for individuals across all quantiles of the BMI distribution and in all the 3 countries. A unit change in the household wealth score was associated with an increase of 0.038, 0.052 and 0.065 units increase in BMI for individuals in the 5th quantile in Ghana, Namibia and Sao Tome and Principe, respectively. Also, 0.237, 0.301 and 0.174 units increased for those in the 90th quantile in Ghana, Namibia and Sao Tome and Principe, respectively. Education had a significant positive effect on maternal BMI across all quantiles in Namibia and negative effect at the 5th, 10th and 90th quantiles in Sao Tome and Principe. Conclusions There is heterogeneity in the effects of DD and SES on maternal BMI. Studies focusing on the effects of diet and socioeconomic determinants on maternal BMI should examine patterns of effects at different points of the conditional distribution of the BMI and not just the average effect.

    Full Text Available Abstract Introduction: Gut microbiota is involved in generation of uremic toxins in chronic kidney disease (CKD patients on hemodialysis (HD, like indoxyl sulfate (IS that is originated from tryptophan amino acid fermentation. Objective: To evaluate the tryptophan intake by chronic renal failure patients on HD and its possible relationship with IS plasma levels. Methods: Participated of the study 46 patients with CKD on HD regular program (56.5% men; 52.7 ± 10.3 years; 63 (32.2-118.2 months on HD; BMI 25.6 ± 4.9 kg/m2. The tryptophan intake was evaluated by a 24-hours dietary recall (R-24h performed on 3 different days. Routine biochemical tests and anthropometric measurements were evaluated. IS plasma levels were determined by High Performance Liquid Chromatography (HPLC with fluorescent detection and the interleukin-6 (IL-6 plasma levels by immunoenzymatic method (ELISA, Enzyme Linked Immunosorbent Assay. Results: The average of tryptophan intake was according to recommendation, but IS plasma levels (35.0 ± 11.9 mg/L were elevated, however according to the EUTox values for uremic individuals. There was no correlation between the tryptophan intake and IS plasma levels. However, there was positive correlation between protein intake and tryptophan and variables used to evaluate lean body mass, and moreover, IS levels were positively associated with IL-6 (r = 0.6: p = 0.01. Conclusion: The present study suggests that tryptophan dietary intake may not be a determinant factor to IS levels. However, it suggests that gut microbiota may play an important role in systemic inflammation in patients with CKD.

  18. Characterizing perfect recall in Epistemic Temporal Logic

    2010-01-01

    We review the notion of perfect recall in the literature on interpreted systems, game theory, and epistemic logic. We give a (to our knowledge) novel frame condition for it, which is local and can straightforwardly be translated to a defining formula in a language that only has next-step temporal operators, such as epistemic temporal logic (ETL). It also gives rise to a complete axiomatization for S5 ETL frames with perfect recall. We then consider how to extend and consolidate the notion of perfect recall in sub-S5 settings, where the various notions discussed are no longer equivalent.

  19. Recalling what was where when seeing nothing there.

    Staudte, Maria; Altmann, Gerry T M

    2016-07-18

    So-called "looks-at-nothing" have previously been used to show that recalling what also elicits the recall of where this was. Here, we present evidence from an eye-tracking study which shows that disrupting looks to "there" does not disrupt recalling what was there, nor do (anticipatory) looks to "there" facilitate recalling what was there. Therefore, our results suggest that recalling where does not recall what.

    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.

  5. Adiabatic Quantum Optimization for Associative Memory Recall

    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.

    Objective To evaluate the dietary pattern and nutritional status of urban residents in southeast coastal area. Methods A dietary survey concerning 1332 persons aged 18 and over was carried out with dietary inquiry and 24-hour recall methods from August to December in 2009. Results The intakes of cereal, meat, eggs, seafood were enough. The consumption of milk and dairy products, vegetables, fruits was insufficient while the amount of oil was too high. Among them, the intake of milk and dairy products was only 1/3 of suggested values in Dietary Guideline and Balanced Diet Pagoda for Chinese Residents. The intakes of protein, retinol, iron and selenium were sufficient, while those of calcium, thiamine, riboflavin, ascorbic acid were too less than the dietary reference intakes (DRIs). Conclusion The dietary pattern of urban residents in Ningbo was not reasonable. Nutrition education should be strengthened to guide residents for planning reasonable and balanced diets.%目的 了解沿海地区城市居民膳食结构以及膳食营养状况.方法 2009年8月~12月在宁波市各区随机对1332名18岁及以上的宁波市城市居民进行了食物频数问卷和24小时膳食回顾现场调查.结果 城市居民对谷类、畜禽肉类、蛋类、水产品的摄入情况较好.但奶类及奶制品、蔬菜、水果摄入量不足,而食用油摄入过量.其中,奶类及奶制品的摄入量只达到膳食指南和平衡膳食宝塔推荐量的1/3.蛋白质、视黄醇、铁、硒的摄入量已达到DRIs标准.而钙、硫胺素、核黄素和抗坏血酸的摄入量严重不足.结论 目前宁波市城市居民膳食结构不够合理,建议大力开展营养宣传教育活动,指导居民合理营养,平衡膳食.

    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.

  9. Memory as a hologram: an analysis of learning and recall.

    Franklin, Donald R J; Mewhort, D J K

    2015-03-01

    We present a holographic theory of human memory. According to the theory, a subject's vocabulary resides in a dynamic distributed representation-a hologram. Studying or recalling a word alters both the existing representation of that word in the hologram and all words associated with it. Recall is always prompted by a recall cue (either a start instruction or the word just recalled). Order of report is a joint function of the item and associative information residing in the hologram at the time the report is made. We apply the model to archival data involving simple free recall, learning in multitrial free recall, simple serial recall, and learning in multitrial serial recall. The model captures accuracy and order of report in both free and serial recall. It also captures learning and subjective organisation in multitrial free recall. We offer the model as an alternative to the short- and long-term account of memory postulated in the modal model.

    Attempts have been made by Rabinowitz, Mandler, and Patterson (AA 527 084) to show that both recall and recognition involve the accessibility of individual words. Their recall tests preceded recognition tests, or vice versa, thus contaminating each other; a fresh experiment is presented to confirm that this is so. (Editor)

    Unsworth, Nash; Brewer, Gene A; Spillers, Gregory J

    2010-06-01

    The dynamics of correct and error responses in a variant of delayed free recall were examined in the present study. In the externalized free recall paradigm, participants were presented with lists of words and were instructed to subsequently recall not only the words that they could remember from the most recently presented list, but also any other words that came to mind during the recall period. Externalized free recall is useful for elucidating both sampling and postretrieval editing processes, thereby yielding more accurate estimates of the total number of error responses, which are typically sampled and subsequently edited during free recall. The results indicated that the participants generally sampled correct items early in the recall period and then transitioned to sampling more erroneous responses. Furthermore, the participants generally terminated their search after sampling too many errors. An examination of editing processes suggested that the participants were quite good at identifying errors, but this varied systematically on the basis of a number of factors. The results from the present study are framed in terms of generate-edit models of free recall.

    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.

    This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.

    Liu, C H; Kennedy, J M

    1994-12-01

    Form symbolism using squares and circles can aid recall. In Experiment 1, subjects saw 20 words, each presented in a circle or a square. Words like SOFT and MOTHER were presented in circles in the "congruent" condition, whereas the same words were presented in squares in the "incongruent" condition. Two experiments revealed that words in the congruent condition were more likely to be recalled. A comparison of the conditions with a baseline condition, in which 20 listed words were not closely related to either of the shapes, suggests that the effect was more likely due to facilitation produced by the congruent condition than to inhibition from the incongruent condition.

    2010-12-01

    The influence of permanent lexical network in immediate serial recall is well established. The corresponding influence of permanent semantic networks is less clear, although such networks are known to both facilitate memory in long-term memory tasks and to produce false memories in those same tasks. The current experiment involves the study of Deese-Roediger-McDermott (DRM) lists for immediate serial recall. The trials in the experiment involved presenting the six strongest items from the DRM lists either in intact associatively related lists or where those items had been randomly mixed to produce unrelated lists. The results of the experiment indicated that the associatively related lists were better recalled in order than unrelated lists and the nonpresented critical lure was falsely recalled relatively frequently. The results of the experiment confirm the importance of associative semantic networks in short-term memory.

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

    Barber, Sarah J; Rajaram, Suparna

    2011-07-01

    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 only to less collaborative inhibition, but also to greater post-collaborative recall benefits. To test this we devised a paradigm to calculate the extent to which each individual experienced retrieval disruption during group recall. We also included two types of collaborative groups, one of which was expected to experience greater retrieval disruption than the other. Results suggest that the relationship between retrieval disruption and recall performance depends on the level at which retrieval disruption is measured. When retrieval disruption was assessed at the individual level, then minimising retrieval disruption was associated with higher recall (i.e., less collaborative inhibition and greater post-collaborative individual recall). However, when retrieval disruption was assessed at the group level there was no relationship with recall. Furthermore, the findings from this design suggest a role of cross-cueing in modulating group recall levels.

    In accordance with the 2010 Dietary Guidelines for Americans, at least half of total grain intake should be whole grains. Adolescents are currently not consuming the recommended daily intake of whole grains. Research is needed to determine whether whole grains are acceptable to adolescents and whether changing their food environment to include whole-grain foods will improve intake. The aim of this study was to determine the effect of providing refined-grain or whole-grain foods to adolescents, with encouragement to eat three different grain-based foods per day, on total grain and whole-grain intakes. Middle school students (n=83; aged 11 to 15 years) were randomly assigned to either refined-grain or whole-grain foods for 6 weeks. Participants and their families were provided with weekly grains (eg, bread, pasta, and cereals), and participants were provided grain snacks at school. Intake of grains in ounce equivalents (oz eq) was determined through eight baseline and intervention targeted 24-hour diet recalls. Participants consumed 1.1±1.3 oz eq (mean±standard deviation) of whole grains at baseline, out of 5.3±2.4 oz eq of total grains. During intervention, whole-grain intake increased in the whole-grain group (0.9±1.0 to 3.9±1.8 oz eq/day), whereas those in the refined-grain group reduced whole-grain intake (1.3±1.6 to 0.3±0.3 oz eq/day; Pgrain intake achieved was 6.4±2.1 oz eq/day and did not differ across intervention groups. Providing adolescents with whole-grain foods in their school and home environments was an effective means of achieving recommendations.

  16. Stimulated recall interviews for describing pragmatic epistemology

    Science.gov (United States)

    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.

    We report a case of radiation recall dermatitis caused by trastuzumab. A 55-year-old woman with metastatic breast cancer received palliative first-line trastuzumab/paclitaxel and a salvage partial mastectomy with lymph node dissection was subsequently performed. In spite of the palliative setting, the pathology report indicated that no residual carcinoma was present, and then she underwent locoregional radiotherapy to ensure a definitive response. After radiotherapy, she has maintained trastuzumab monotherapy. Nine days after the fifth cycle of trastuzumab monotherapy, dermatitis in previously irradiated skin developed, with fever. Radiation recall dermatitis triggered by trastuzumab is extremely rare. A high fever developed abruptly with a skin rash. This may be the first case of this sort to be reported.

    Evidence suggests that diet plays an important role in the development of mental disorders, especially anxiety. Dietary diversity score is an indicator for assessing diet quality. However, its association with anxiety has not been investigated. The aim of this study was to examine the association of dietary diversity score with anxiety. A cross-sectional study was conducted among 360 women attending health centers in the south of Tehran in 2014. General information among others were collected. Weight, height and waist circumference were measured and body mass index (BMI) was calculated. Dietary intake and anxiety score were assessed using a 24-h dietary recall and Depression, Anxiety, Stress Scales (DASS) questionnaires, respectively. Dietary diversity score was computed according to the guidelines of FAO. About 35% of the participants were found to exhibit anxiety. The dietary diversity score in 12.5% of the subjects were between 1 and 3 (low dietary diversity score) but 87.5% scored between 4 and 7 (high dietary diversity score). The adjusted mean of anxiety score in subjects with high dietary diversity score was significantly lower than those with low dietary diversity score. Dietary diversity score was found to be inversely associated with anxiety. However, the causality between anxiety and dietary diversity could not be determined.

    2007-04-15

    Background: Radiation recall pneumonitis describes a very rare reaction in a previously irradiated area of pulmonary tissue after application of pharmacological agents. A case of recall pneumonitis induced by gemcitabine is reported. Case Report: A 64-year-old female patient with metastasized esophageal carcinoma received simultaneous chemoradiotherapy of the upper mediastinum with 50.4 Gy and cisplatin/5-fluorouracil. 8 months later she was scheduled for salvage chemotherapy with gemcitabine (1,000 mg/m2 days 1 and 8) and docetaxel (75 mg/m2 day 8) due to locally progressive disease. After having received gemcitabine on day 1 of the second course, the patient developed dry cough, subfebrile temperatures and dyspnea within 48 h. A CT of the thorax revealed newly developed bilateral pulmonary ground-glass opacity corresponding to the previous radiation fields. Chemotherapy was stopped and systemic application of prednisolone was initiated. 2 months later symptoms had resolved with a control CT of the thorax showing complete regression of the pulmonary changes. Conclusion: Gemcitabine-induced recall pneumonitis is a rarely reported phenomenon and should be taken into account even after extended time interval to the previous radiotherapy.

    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

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

    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.

    In this study, the author examined the effects of intention to learn, noise, and different types of orienting tasks on short-term and long-term recall for 15 Hindi paired-associates. Intention to learn improved recall, as did encoding of semantic features, and noise impaired both short-term and long-term recall. The analysis of short-term recall scores indicated that there were no significant interactions between these factors, but the analysis of long-term recall scores indicated that there were significant interactions between noise and orienting tasks and between intentionality and orienting tasks.

    Science.gov (United States)

    Reysen, Matthew B

    2003-12-01

    In two experiments, individual subjects worked in conjunction with two perceived group members to recall six 30-item categorized word lists. The perceived group members' recall levels were manipulated to establish either high or low group standards. After participating in the perceived group, subjects completed a surprise final individual recall test that covered all of the presented material. On the basis of the hypothesis that the subjects' performance would be affected by social pressure, it was predicted that subjects working in high-performing groups would recall more words than subjects working in low-performing groups on both the group recall tests and the final individual recall test. These predicted results were observed. Thus, a complete analysis of the group recall environment should include a consideration of conformity theory whereby subjects' memories can be affected by their group members' output levels.

    The configuration, components, specifications and costs of a state-of-the-art closed-circuit television system with wide application for wildlife research and management are described. The principal system components consist of color CCTV camera with zoom lens, pan/tilt system, infrared illuminator, heavy duty tripod, coaxial cable, coaxitron system, half-duplex equalizing video/control amplifier, timelapse video cassette recorder, color video monitor, VHS video cassettes, portable generator, fuel tank and power cable. This system was developed and used in a study of Mississippi sandhiIl Crane (Grus canadensis pratensis) behaviors during incubation, hatching and fledging. The main advantages of the system are minimal downtime where a complete record of every event, its time of occurrence and duration, are permanently recorded and can be replayed as many times as necessary thereafter to retrieve the data. The system is particularly applicable for studies of behavior and predation, for counting individuals, or recording difficult to observe activities. The system can be run continuously for several weeks by two people, reducing personnel costs. This paper is intended to provide biologists who have litte knowledge of electronics with a system that might be useful to their specific needs. The disadvantages of this system are the initial costs (about $9800 basic, 1990-1991 U.S. dollars) and the time required to playback video cassette tapes for data retrieval, but the playback can be sped up when litte or no activity of interest is taking place. In our study, the positive aspects of the system far outweighed the negative.

    The maximal aerobic performance (VO2 max) and energy costs of cycling at various power outputs and equivalent road speeds of a highly trained endurance cyclist (age 23.4 yrs, height 1.95 m, weight 73.1 kg), were measured in the laboratory on an eddy-current cycle ergometer, and the physiological responses related to determinations made during a 24 h cycling time trial event, using continuous ECG recording from which estimates of ergogenic demands were obtained. The cyclist covered a distance of 694 km during the event at an average speed of 28.9 km.h-1 which corresponded to an equivalent oxygen cost of 38.5 ml.kg-1 min-1 and represented approximately 55% of his VO2 max. During the event, the cyclist expended an estimated 82,680 kJ of energy, of which approximately 44,278 kJ (54%) were supplied by repeated feedings of liquids, solids and semi-solids and some 38,402 kJ (46%) came from the stored energy reserves which resulted in a 1.19 kg loss of body weight during the event. The energy demands of the activity were more than three times greater than the highest recorded values of severe industrial work, and similar to the hourly rates of expenditure of shorter duration competitive events, but above the highest values reported over other extreme endurance events over the same period of time. The results thus represent near maximal levels of sustainable ergogenic effort by man over a complete 24 h cycle.

    Objective To describe and analyze the dietary pattern and nutritional status of adult residents in Hubei province. Methods This paper was based on the data of Hubei province,collected in the China Health and Nutrition Survey in 2006 ,and the subjects were 18 -45 year-old healthy adults. 24-hour dietary recall method (for 3 consecutive days) and weighting method were used in dietary survey. The criterion for defining overweight for adults was body mass index (BMI)of≧24 kg/m2. Results The daily consumption of fruit and dairy product for adults were too low,while the consumption of dietary fat and cooking salt were too high. Excessive meat consumption in urban, and inadequate fishery product consumption existed both in urban and rural area. The intake of energy and protein were satisfactory,while the intake of fat was overmuch on the whole. The proportion of energy,protein and fat supplied from animal food were the highest in urban. The average intake of thiamine,riboflavin and calcium were obviously insufficient. The prevalence of underweight and overweight among Hubei adults were 5.2 % and 32. 3% respectively. The difference of dietary pattern and nutritional status between different gender and different areas were shortening. Conclusions The dietary quality has significandy improvod, however,some specific and imbalanced dietary patterns and nutritional status in common still exist in Hubei residents. Some targeted measures should be taken to effectively control overweight and obesity so as to improve the health of the residents.%目的 分析湖北省成人膳食与营养状况.方法 以2006年"中国居民健康与营养调查"湖北省资料中18~45岁健康成人作为研究对象,膳食调查采用连续3 d 24 h回顾法和家庭食物称重法,以体质指数(BMI)≥24作为判断成人超重标准.结果 湖北省成人水果和奶类消费普遍过低,油脂和食盐消费过高,其中城市居民肉类消费偏高,县城和农村居民水产品消

    Recent studies suggest that the content of confabulation is mainly positive and self-enhancing. In this group study, we aimed to investigate whether this positive bias is specific to self-referent information. Confabulating amnesic patients, amnesic non-confabulating patients and healthy controls were asked to reproduce a series of short stories. We manipulated the emotional valence of the material by including positive, negative and neutral story plots. We also manipulated the self-reference of the material by including self-referent versus other-referent encoding instructions. Confabulating patients were as impaired as a group of amnesic patients in the amount of information they recalled, both groups being worse than healthy controls. Importantly, confabulating patients showed a selective bias in the negative self-referent condition, in that they recalled such information in a manner which portrayed a more positive image of themselves. This positive bias was not present in stories that were not encoded in a self-referent manner and it was not significantly correlated to patients' self-reported mood. We propose that both confabulation and its motivated content result from a deficit in the control and regulation of memory retrieval, which allows motivational factors to acquire a greater role than usual in determining which memories are selected for retrieval. To this extent, the self-enhancing content of confabulation could be explained as a neurogenic exaggeration of normal self-serving memory distortion.

    2000-01-01

    Full Text Available Amnesic patients were compared to a healthy control group on recall of word lists containing semantically-related or unrelated words. As expected on the basis of previous literature, the amnesic group performed below the control group on all measures of recall. When total recall scores for each list were used as the index of performance, their scores were not significantly affected by the type of list, unlike those of the control group. Comparison of serial position effects for different parts of the lists revealed that the control group derived greater benefit from semantic relatedness in recall of items from the middle positions. This effect was not shown by the amnesic group, who showed similar U-shaped serial position curves for recall of all three lists, and appeared to use a more passive recall strategy than the control group. The findings are discussed in relation to our current understanding of amnesic deficits.

    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.

    BACKGROUND There is a need for culturally-relevant nutrition programs targeted to underserved cancer survivors. OBJECTIVE To examine the effect of a culturally-based approach to dietary change on increasing fruit/vegetable intake and decreasing fat intake among Hispanic breast cancer (BC) survivors. DESIGN Participants were randomized to intervention (IG) and control (CG) groups. Diet recalls, detailed interviews, fasting blood, and anthropometric measures were collected at baseline, 3-, 6- and 12-months. PARTICIPANTS/SETTING Hispanic women (n=70) with stage 0-III BC who completed adjuvant treatment and lived in New York City were randomized between April 2011 and March 2012. INTERVENTION The IG (n=34) participated in ¡Cocinar Para Su Salud! (¡CPSS!), a culturally-based 9-session (24-hours over 12 weeks) intervention including nutrition education, cooking classes and food shopping field trips. The CG (n=36) received written dietary recommendations for BC survivors. MAIN OUTCOME MEASURES Change at 6 months in daily fruit/vegetable servings and % calories from total fat. STATISTICAL ANALYSES Linear regression models adjusted for stratification factors and estimated marginal means were used to compare changes in diet from baseline to 3- and 6-months. RESULTS Baseline characteristics: mean age 56.6 years (SD 9.7), mean time since diagnosis 3.4 years (SD 2.7), mean BMI 30.9 kg/m2 (SD 6.0), 62.9% with annual household income ≤$15,000, average daily servings of all fruits/vegetables 5.3 (targeted fruits/vegetables 3.7 servings excluding legumes/juices/starchy vegetables/fried foods) and 27.7% of daily calories from fat. Over 60% in the IG attended ≥7/9 classes with overall study retention of 87% retention at 6 months. At month 6, the IG compared to CG reported an increase in mean servings of fruits/vegetables from baseline (all fruits/vegetables: +2.0 vs. −0.1, P=0.005; targeted fruits/vegetables: +2.7 vs. +0.5, P=0.002) and a non-significant decrease in

    Since 2003/2004, the United Kingdom has implemented a salt reduction campaign; however, there are no data on salt intake in children as assessed by 24-hour urinary sodium, the gold standard method, to inform this campaign. We performed a cross-sectional study, involving South London school children across 3 age tiers: young children (5- to 6-year olds), intermediate-aged children (8- to 9-year olds), and adolescents (13- to 17-year olds). Dietary salt intake was measured by 24-hour urinary sodium excretion and compared with newly derived maximum salt intake recommendations. In addition, dietary sources of salt were assessed using a 24-hour photographic food diary. Valid urine collections were provided by 340 children (162 girls, 178 boys). The mean salt intakes were 3.75 g/d (95% confidence interval, 3.49-4.01), 4.72 g/d (4.33-5.11), and 7.55 g/d (6.88-8.22) for the 5- to 6-year olds, 8- to 9-year olds, and 13- to 17-year olds, respectively. Sixty-six percent of the 5- to 6-year olds, 73% of the 8- to 9-year olds, and 73% of 13- to 17-year olds had salt intake above their maximum daily intake recommendations. The major sources of dietary salt intake were cereal and cereal-based products (36%, which included bread 15%), meat products (19%), and milk and milk products (11%). This study demonstrates that salt intake in children in South London is high, with most of the salt coming from processed foods. Much further effort is required to reduce the salt content of manufactured foods.

  13. Dietary fiber.

    1987-01-01

    Studies done on dietary fiber (DF) over the past five years are presented in this Review. The involvement of dietary fiber in the control of plasma glucose and lipid levels is now established. Two dietary fiber sources (soybean and fenugreek) were studied in our laboratory and are discussed herein. These sources were found to be potentially beneficial in the reduction of plasma glucose in non-insulin dependent diabetes mellitus subjects. They are shown to be acceptable by human subjects and are easy to use either in a mixture of milk products and in cooking. The mechanism by which dietary fiber alters the nutrient absorption is also discussed. The effect of DF on gastric emptying, transit time, adsorption and glucose transport may contribute to reducing plasma glucose and lipid levels. DF was found to be effective in controlling blood glucose and lipid levels of pregnant diabetic women. Dietary fiber may also be potentially beneficial in the reduction of exogenous insulin requirements in these subjects. However, increased consumption of DF may cause adverse side effects; the binding capabilities of fiber may affect nutrient availability, particularly that of minerals and prolonged and high DF dosage supplementation must be regarded cautiously. This is particularly true when recommending such a diet for pregnant or lactating women, children or subjects with nutritional disorders. Physiological effects of DF appear to depend heavily on the source and composition of fiber. Using a combination of DF from a variety of sources may reduce the actual mass of fiber required to obtain the desired metabolic effects and will result in a more palatable diet. Previously observed problems, such as excess flatus, diarrhea and mineral malabsorption would also be minimized.

    The 2013 Institute of Medicine (IOM) report "Sodium Intake in Populations: Assessment of Evidence" did not support the current recommendations of the IOM and the American Heart Association (AHA) to reduce daily dietary sodium intake to below 2,300 mg. The report concluded that the population......-based health outcome evidence was not sufficient to define a safe upper intake level for sodium. Recent studies have extended this conclusion to show that a sodium intake below 2,300 mg/day is associated with increased mortality.

    Moè, Angelica

    2016-11-01

    Displayed enthusiasm has been shown to relate to intrinsic motivation, vitality, and positive affect, but its effects on recall performance and time estimation have not yet been explored. This research aimed at studying the effects of a delivery style characterised by High Enthusiasm (HE) on recall, time estimation, and intrinsic motivation. In line with previous studies, effects on intrinsic motivation were expected. In addition, higher recall and lower time estimations were hypothesised. In two experiments, participants assigned to a HE condition or to a normal reading control condition listened to a narrative and to a descriptive passage. Then, they were asked to rate perceived time, enthusiasm, pleasure, interest, enjoyment and curiosity, before writing a free recall. Experiment 1 showed that in the HE condition, participants recalled more, were more intrinsically motivated, and expressed lower time estimations compared to the control condition. Experiment 2 confirmed the positive effects of HE reading compared to normal reading, using different passages and a larger sample.

  13. Recall versus familiarity when recall fails for words and scenes: the differential roles of the hippocampus, perirhinal cortex, and category-specific cortical regions.

    Ryals, Anthony J; Cleary, Anne M; Seger, Carol A

    2013-01-25

    This fMRI study examined recall and familiarity for words and scenes using the novel recognition without cued recall (RWCR) paradigm. Subjects performed a cued recall task in which half of the test cues resembled studied items (and thus were familiar) and half did not. Subjects also judged the familiarity of the cue itself. RWCR is the finding that, among cues for which recall fails, subjects generally rate cues that resemble studied items as more familiar than cues that do not. For words, left and right hippocampal activity increased when recall succeeded relative to when it failed. When recall failed, right hippocampal activity was decreased for familiar relative to unfamiliar cues. In contrast, right Prc activity increased for familiar cues for which recall failed relative to both familiar cues for which recall succeeded and to unfamiliar cues. For scenes, left hippocampal activity increased when recall succeeded relative to when it failed but did not differentiate familiar from unfamiliar cues when recall failed. In contrast, right Prc activity increased for familiar relative to unfamiliar cues when recall failed. Category-specific cortical regions showed effects unique to their respective stimulus types: The visual word form area (VWFA) showed effects for recall vs. familiarity specific to words, and the parahippocampal place area (PPA) showed effects for recall vs. familiarity specific to scenes. In both cases, these effects were such that there was increased activity occurring during recall relative to when recall failed, and decreased activity occurring for familiar relative to unfamiliar cues when recall failed.

    The purposes of this research were to examine the characteristics of those who look for physical activity-related information, where they find it, and to examine what types of physical activity-related advertisements are recalled (i.e., publicly funded or commercial). These purposes were tested using secondary data analyses from two population health surveys. Results from the first survey (n=1211) showed gender, age, education, and activity-level differences in who is more likely to search for physical activity-related information. Adding the goal of being active into the model made age and activity level no longer significant but gender and education remained significant factors. The Internet was the most often cited source of physical activity information. The second survey (n=1600) showed that adults 55 years of age or older and participants with the least amount of education were more than twice as likely to name commercial advertisements than were participants aged 18-54 years or those with more education. These results help further our understanding of how publicly funded promotional campaigns fare against commercial advertising and also highlight the need to understand physical activity information-seeking behavior on the Internet and its implications for health promotion.

  17. Conditional recall and the frequency effect in the serial recall task: an examination of item-to-item associativity.

    Science.gov (United States)

    Miller, Leonie M; Roodenrys, Steven

    2012-11-01

    The frequency effect in short-term serial recall is influenced by the composition of lists. In pure lists, a robust advantage in the recall of high-frequency (HF) words is observed, yet in alternating mixed lists, HF and low-frequency (LF) words are recalled equally well. It has been argued that the preexisting associations between all list items determine a single, global level of supportive activation that assists item recall. Preexisting associations between items are assumed to be a function of language co-occurrence; HF-HF associations are high, LF-LF associations are low, and mixed associations are intermediate in activation strength. This account, however, is based on results when alternating lists with equal numbers of HF and LF words were used. It is possible that directional association between adjacent list items is responsible for the recall patterns reported. In the present experiment, the recall of three forms of mixed lists-those with equal numbers of HF and LF items and pure lists-was examined to test the extent to which item-to-item associations are present in serial recall. Furthermore, conditional probabilities were used to examine more closely the evidence for a contribution, since correct-in-position scoring may mask recall that is dependent on the recall of prior items. The results suggest that an item-to-item effect is clearly present for early but not late list items, and they implicate an additional factor, perhaps the availability of resources at output, in the recall of late list items.

    The kidney is an important organ that makes that exist equilibrium inside the organism. In it' s multiple functions, one that interests us to know is the glomerular filtration rate (GFR). To know this, exist laboratory and scintigraphy studies like the scintigraphy with technique of Gates and the creatinine purification in urine of 24 hours. The files of 44 patients were studied, which were clinically candidates to kidney donors healthy (25 women and 19 men) with ages that varied from the 18 years to the 54 years ( 35.1 years), with a weight of 43 kilograms to 94 kilograms (68.95 Kg) and with a corporal surface of 1.29 to 2.08 m{sup 2} (1.70 m{sup 2}). These patients underwent study protocols with creatinine purification and with renal scintigraphy. The glomerular filtration rate obtained by creatinine purification varied from 51.9 ml/min. to 156 ml/min. and the GFR obtained by scintigraphy varied from 3.6 ml/min. to 155.2 ml/min. Once obtained the gathering of data the test of Student was applied to compare the averages of both distributions and the analysis of lineal regression to determine the coefficients of correlation of the complete group.

    Full Text Available Purpose: To see if there is a correlation between interference and short-term memory recall and to examine interference as a factor affecting memory recalling of Arabic and abstract words through free, cued, and serial recall tasks. Method: Four groups of undergraduates in King Saud University, Saudi Arabia participated in this study. The first group consisted of 9 undergraduates who were trained to perform three types of recall for 20 Arabic abstract and concrete words. The second, third and fourth groups consisted of 27 undergraduates where each group was trained only to perform one recall type: free recall, cued recall and serial recall respectively. Interference (short-term memory interruption was the independent variable and a number of recalled abstract and concrete words was the dependent variable. The used materials in this study were: abstract and concrete words classification form based on four factors was distributed to the participants (concreteness, imageability, meaningfulness, and age of acquisition, three oral recall forms, three written recall forms, and observation sheets for each type of recall. Also, three methods were used: auditory, visual, and written methods. Results: Findings indicated that interference effect on short-term memory recall of Arabic abstract and concrete words was not significant especially in the case of free and serial recall paradigms. The difference between the total number of recalled Arabic abstract and concrete words was also very slight. One other the hand, we came to the conclusion that Pearson’s correlation between interference at these memory recall paradigms (M: 1.66, SD= .47 and the short-term memory recall (M: 1.75, SD= .43 supported the research hypothesis that those participants with oral interruptions tended to recall slightly less Arabic abstract and concrete words, whereas those participants with no oral interruptions would tend to recall slightly more Arabic abstract and concrete

    In a sample of 71 medical students, dream recall frequency was positively correlated with proneness to altered states of consciousness (r = .26) measured by the State of Mind and Consciousness Questionnaire and dissociation (r = .29) measured by the Dissociative Experiences Scale II. A regression analysis, however, yielded neither altered states of consciousness nor dissociation, sex, or age to be significant predictors of dream recall frequency. Among women dream recall frequency was associated with proneness to dissociation; among men it was correlated with proneness to altered states of consciousness.

    This study aimed to examine the effects of the presence or absence of an immediate recall trial on university students' (n = 39) performance on the one-year delayed recall test in the Rey complex figure test (RCFT). Participants were divided into two groups that took either one or two tests, respectively. In the first year, the participants in the two-test condition completed a copy trial and an immediate recall trial, whereas those in the one-test condition underwent the copy trial only. In the second year, all participants completed a delayed recall test. Those in the two-test condition showed significantly higher scores than those in the one-test condition on the one-year delayed recall test. Thus, we found that omitting the immediate recall trial caused a decline in performance on the one-year delayed recall test. The relevance of these findings to the relationship with testing effects (Roediger & Karpicke, 2006 ) was considered.

    Full Text Available Abstract Background High plasma uric acid (UA is a prerequisite for gout and is also associated with the metabolic syndrome and its components and consequently risk factors for cardiovascular diseases. Hence, the management of UA serum concentrations would be essential for the treatment and/or prevention of human diseases and, to that end, it is necessary to know what the main factors that control the uricemia increase. The aim of this study was to evaluate the main factors associated with higher uricemia values analyzing diet, body composition and biochemical markers. Methods 415 both gender individuals aged 21 to 82 years who participated in a lifestyle modification project were studied. Anthropometric evaluation consisted of weight and height measurements with later BMI estimation. Waist circumference was also measured. The muscle mass (Muscle Mass Index – MMI and fat percentage were measured by bioimpedance. Dietary intake was estimated by 24-hour recalls with later quantification of the servings on the Brazilian food pyramid and the Healthy Eating Index. Uric acid, glucose, triglycerides (TG, total cholesterol, urea, creatinine, gamma-GT, albumin and calcium and HDL-c were quantified in serum by the dry-chemistry method. LDL-c was estimated by the Friedewald equation and ultrasensitive C-reactive protein (CRP by the immunochemiluminiscence method. Statistical analysis was performed by the SAS software package, version 9.1. Linear regression (odds ratio was performed with a 95% confidence interval (CI in order to observe the odds ratio for presenting UA above the last quartile (♂UA > 6.5 mg/dL and ♀ UA > 5 mg/dL. The level of significance adopted was lower than 5%. Results Individuals with BMI ≥ 25 kg/m2 OR = 2.28(1.13-4.6 and lower MMI OR = 13.4 (5.21-34.56 showed greater chances of high UA levels even after all adjustments (gender, age, CRP, gamma-gt, LDL, creatinine, urea, albumin, HDL-c, TG, arterial

    The curious free recall data of Murdock (1962) shows an additional surprise that seems to have gone undetected until now: the probability of guessing an item in the initial recall is not identical to the overall free recall curve. Initial recall of an item is well correlated with the total recall of that item using a straight line but with an unexpected offset. The offset varies with the presentation rate and the total number of list items but in each case it is the same as the total recall ...

  8. Recalling of Images using Hopfield Neural Network Model

    CERN Document Server

    Ramya, C; Shreedhara, Dr K S

    2011-01-01

    In the present paper, an effort has been made for storing and recalling images with Hopfield Neural Network Model of auto-associative memory. Images are stored by calculating a corresponding weight matrix. Thereafter, starting from an arbitrary configuration, the memory will settle on exactly that stored image, which is nearest to the starting configuration in terms of Hamming distance. Thus given an incomplete or corrupted version of a stored image, the network is able to recall the corresponding original image. The storing of the objects has been performed according to the Hopfield algorithm explained below. Once the net has completely learnt this set of input patterns, a set of testing patterns containing degraded images will be given to the net. Then the Hopfield net will tend to recall the closest matching pattern for the given degraded image. The simulated results show that Hopfield model is the best for storing and recalling images.

    Undergraduate volunteers rated a series of words for pleasantness while hearing a particular background music. The subjects in Experiment 1 received, immediately or after a 48-h delay, an unexpected word-recall test in one of the following musical cue contexts: same cue (S), different cue (D), or no cue (N). For immediate recall, context dependency (S-D) was significant but same-cue facilitation (S-N) was not. No cue effects at all were found for delayed recall, and there was a significant interaction between cue and retention interval. A similar interaction was also found in Experiment 3, which was designed to rule out an alternative explanation with respect to distraction. When the different musical selection was changed specifically in either tempo or form (genre), only pieces having an altered tempo produced significantly lower immediate recall compared with the same pieces (Experiment 2). The results support a stimulus generalization view of music-dependent memory.

    2014-01-01

    How does the brain allow us to recall numerous life experiences despite there often being a high degree of similarity between memories? This is a key question in neuroscience. Moreover, there is also keen interest in understanding why some people are able to recall memories with greater clarity than other people. In this study, we identified a specific brain region, CA3, an area within a structure called the hippocampus, and a mechanism within it that helps to explain individual differences i...

    Baddeley and Wilson [Baddeley, A. D., & Wilson, F. B. (2002). Prose recall and amnesia: implications for the structure of working memory. Neuropsychologia 40, 1737-1743.] have argued that their finding of a positive association between amnesics' immediate prose recall scores and their scores on measures of executive function and fluid intelligence supports the view that an episodic buffer exists. However, the pattern of data from amnesics tested in our laboratory presented some problems for this conceptualisation of the episodic buffer.

    The concept of qth order Hamming ball for general bidirectional associative memories (GBAMs) is presented, which results in an enhanced recall capability. A technique based on the minimum overlap algorithm (MOA) is proposed to deal with the separability problem of the qth order Hamming balls. Simulation results show that the recall capability obtained by using the proposed method is indeed larger than that obtained by using the conventional method.

  14. Women with high scores for cognitive dietary restraint choose foods lower in fat and energy.

    Women with high dietary restraint typically report restricting energy intake and using reduced-kilocalorie foods in an effort to achieve or maintain a certain body weight. However, previous studies of food choices associated with dietary restraint have been limited by the self-report of participants' food selections. We provided all foods consumed during a free-living 24-hour period to 62 normal-weight women with high (n=33) or low (n=29) dietary restraint, and observed choices from among similar foods varying in fat, fiber, and energy content. Women with high dietary restraint consumed less energy and chose reduced-kilocalorie and reduced-fat foods more frequently than unrestrained eaters. Group differences in choices of milk, cream cheese, mayonnaise, salad dressing, and soda were noted. Dietitians may consider frequent use of reduced-kilocalorie and reduced-fat foods a potential indicator of high dietary restraint, which may have health consequences. Accordingly, further exploration of clients' tendency to restrict dietary intake may be warranted.

    Patient safety programs have been developed in many hospitals to reduce the risk of harm to patients. Proactive, real-time, and retrospective risk-reduction strategies should be implemented in hospitals, but patient safety leaders should also be cognizant of the risks associated with thousands of products that enter the hospital through the supply chain. A growing number of recalls and alerts related to these products are received by health care facilities each year, through a recall process that is fraught with challenges. Despite the best efforts of health care providers, weaknesses and gaps in the process lead to delays, fragmentation, and disruptions, thus extending the number of days patients may be at risk from potentially faulty or misused products. To address these concerns, Duke Medicine, which comprises an academic medical center, two community hospitals, outlying clinics, physicians' offices, and home health and hospice, implemented a Web-based recall management system. Within three months, the time required to receive, deliver, and close alerts decreased from 43 days to 2.74 days. To maximize the effectiveness of the recall management process, a team of senior Duke Medicine leaders was established to evaluate the impact of product recalls and alerts on patient safety, to evaluate response action plans, and to provide oversight of patient and provider communication strategies. Alerts are now communicated more effectively and responded to in a more consistent and global manner. This comprehensive approach to product recalls is a critical component of a broader Duke Medicine strategy to improve patient safety.

    Many cortical disorders are associated with memory problems. In schizophrenia, verbal memory deficits are a hallmark feature. However, the exact nature of this deficit remains elusive. Modeling aspects of language features used in memory recall have the potential to provide means for measuring these verbal processes. We employ computational language approaches to assess time-varying semantic and sequential properties of prose recall at various retrieval intervals (immediate, 30 min and 24 h later) in patients with schizophrenia, unaffected siblings and healthy unrelated control participants. First, we model the recall data to quantify the degradation of performance with increasing retrieval interval and the effect of diagnosis (i.e., group membership) on performance. Next we model the human scoring of recall performance using an n-gram language sequence technique, and then with a semantic feature based on Latent Semantic Analysis. These models show that automated analyses of the recalls can produce scores that accurately mimic human scoring. The final analysis addresses the validity of this approach by ascertaining the ability to predict group membership from models built on the two classes of language features. Taken individually, the semantic feature is most predictive, while a model combining the features improves accuracy of group membership prediction slightly above the semantic feature alone as well as over the human rating approach. We discuss the implications for cognitive neuroscience of such a computational approach in exploring the mechanisms of prose recall.

    Full Text Available Nutritional state in the gestation period influences fetal growth and development. We hypothesized that undernutrition during gestation would affect offspring sleep architecture and/or homeostasis. Pregnant female mice were assigned to either control (fed ad libitum; AD or 50% dietary restriction (DR groups from gestation day 12 to parturition. After parturition, dams were fed AD chow. After weaning, the pups were also fed AD into adulthood. At adulthood (aged 8-9 weeks, we carried out sleep recordings. Although offspring mice displayed a significantly reduced body weight at birth, their weights recovered three days after birth. Enhancement of electroencephalogram (EEG slow wave activity (SWA during non-rapid eye movement (NREM sleep was observed in the DR mice over a 24-hour period without changing the diurnal pattern or amounts of wake, NREM, or rapid eye movement (REM sleep. In addition, DR mice also displayed an enhancement of EEG-SWA rebound after a 6-hour sleep deprivation and a higher threshold for waking in the face of external stimuli. DR adult offspring mice exhibited small but significant increases in the expression of hypothalamic peroxisome proliferator-activated receptor α (Pparα and brain-specific carnitine palmitoyltransferase 1 (Cpt1c mRNA, two genes involved in lipid metabolism. Undernutrition during pregnancy may influence sleep homeostasis, with offspring exhibiting greater sleep pressure.

    Patients with Alzheimer's disease (AD) suffer from distortions of memory. Among such distortions, intrusions in memory tests are frequently observed. In this study we describe the performance of a group of mild AD patients and a group of normal controls on the recall of three different types of stories: a previously unknown story, a well-known fairy-tale (Cinderella), and a modified well-known fairy-tale (Little Red Riding Hood is not eaten by the wolf). The aim of our study was to test the hypothesis that in patients who tend to produce intrusions, over-learned information interferes with episodic recall, i.e., the retrieval of specific, unique past episodes. AD patients produced significantly more intrusions in the recall of the modified fairy-tale compared to the recall of the two other stories. Intrusions in the recall of the modified fairy-tale always consisted of elements of the original version of the story. We suggest that in AD patients intrusions may be traced back to the interference of strongly represented, over-learned information in episodic memory recall.

    There has been great interest in using working memory (WM) training regimens as an alternative treatment for ADHD, but it has recently been concluded that existing training regimens may not be optimally designed because they target the primary memory component but not the secondary component of WM capacity. This conclusion requires the ability to accurately measure changes in primary and secondary memory abilities over time. The immediate free recall task has been used in previous studies to measure these changes; however, one concern with these tasks is that the recall order required on training exercises may influence the recall strategy used during free recall, which may in turn influence the relative number of items recalled from primary and secondary memory. To address this issue, previous training studies have explicitly controlled recall strategy before and after training. However, the necessity of controlling for recall strategies has not been explicitly tested. The present study investigated the effects of forward-serial-order training on free recall performance under conditions in which recall strategy was not controlled using a sample of adolescents with ADHD. Unlike when recall order was controlled, the main findings showed selective improvement of the secondary memory component (as opposed to the primary memory component) when recall order was uncontrolled. This finding advances our understanding of WM training by highlighting the importance of controlling for recall strategies when free recall tasks are used to measure changes in the primary and secondary components of WM across time.

    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.

    Objective Studies suggest protein intake may be associated with lower body weight, but protein has also been associated with preservation of lean body mass. Understanding the role of protein in maintaining health for older adults is important for disease prevention among this population. Design Cross-sectional study of the relationship of dietary protein on body composition. Setting New York City community centers Participants 1,011 Black, White, and Latino urban men and women 60-99 years of age Measurements Protein intake was assessed using two interviewer-administered 24-hour recalls, and body composition was assessed using bioelectrical impedance analysis (BIA) of fat mass (kg) (FM), fat free mass (kg) (FFM), and impedance resistance (Ohms). Statistical Analysis Indices of FM and FFM were calculated by dividing BIA measurements by height squared (m2), and percent FFM was calculated by dividing FFM by the sum of FM and FFM. Log linear models adjusting for age (continuous), race/ethnicity, education, physical activity (dichotomized at the median), hypertension, diabetes, and total calories (continuous). Results Just 33% of women and 50% of men reported meeting the RDA for protein. Both fat free mass index (FFMI) and fat mass index (FMI) were negatively associated with meeting the RDA for protein (Women: FFMI -1.78 95%CI [-2.24, -1.33], FMI -4.12 95% CI[-4.82, -3.42] Men: FFMI -1.62 95% CI [-2.32, -0.93] FMI -1.80 95% CI [-2.70, -0.89]).After accounting for confounders, women and men consuming at least 0.8 g/kg/day had a 6.2% (95% CI: 5.0%, 7.4%) and a 3.2% (95% CI 1.1%, 5.3%) higher percent fat free mass, respectively. Conclusions FFM, FFMI, FM, and FMI were inversely related to meeting the RDA for protein. Meeting the RDA for protein of at least 0.8g/kg/day was associated with a higher percentage of fat free mass among older adults. These results suggest meeting the protein recommendations of at least 0.8 g/kg/day may help to promote lower overall body mass

  10. Superior Memorizers Employ Different Neural Networks for Encoding and Recall

    2015-09-01

    Full Text Available Superior memorizers often employ the method of loci (MoL to memorize large amounts of information. The method of loci, known since ancient times, relies on a complex process where information to be memorized is bound to landmarks along mental routes in a previously memorized environment. However, fMRI data on groups of trained superior memorizer are rare. Based on the memorizing strategy reported by superior memorizers we developed a scheme of the processes successively employed during memorizing and recalling digits and relate these to brain activation that is specific for the encoding and recall period. In the examined superior memorizers several regions, suggested to be involved in mental navigation and digit-to-word processing, were specifically activated during encoding: bilateral early visual cortex, retrosplenial cortex, left parahippocampus, left visual cortex, and left superior parietal cortex. Although the scheme suggests that some steps during encoding and recall seem to be analog, none of the encoding areas were specifically activated during the recall. Instead, we found strong activation in left anterior superior temporal gyrus, which we relate to recalling the sequential order of the digits, and right motor cortex that may be related to reciting the digits.

    Full Text Available Prior knowledge is known to facilitate learning new information. Normally in studies confirming this outcome the relationship between prior knowledge and the topic to be learned is obvious: the information to be acquired is part of the domain or topic to which the prior knowledge belongs. This raises the question as to whether prior knowledge of various domains facilitates recalling information. In this study 79 eleventh-grade students completed a questionnaire on their prior knowledge of seven different domains related to the bioethical dilemma of prenatal diagnostics. The students read a text containing arguments for and arguments against prenatal diagnostics. After one week and again 12 weeks later they were asked to write down all the arguments they remembered. Prior knowledge helped them recall the arguments one week (r = .350 and 12 weeks (r = .316 later. Prior knowledge of three of the seven domains significantly helped them recall the arguments one week later (correlations between r = .194 to r = .394. Partial correlations with interest as a control item revealed that interest did not explain the relationship between prior knowledge and recall.

    Patients' beliefs about the origin of their pain and their cognitive processing of pain-related information have both been shown to be associated with poorer prognosis in low back pain (LBP), but the relationship between specific beliefs and specific cognitive processes is not known. The aim of this study was to examine the relationship between diagnostic uncertainty and recall bias in 2 groups of chronic LBP patients, those who were certain about their diagnosis and those who believed that their pain was due to an undiagnosed problem. Patients (N=68) endorsed and subsequently recalled pain, illness, depression, and neutral stimuli. They also provided measures of pain, diagnostic status, mood, and disability. Both groups exhibited a recall bias for pain stimuli, but only the group with diagnostic uncertainty also displayed a recall bias for illness-related stimuli. This bias remained after controlling for depression and disability. Sensitivity analyses using grouping by diagnosis/explanation received supported these findings. Higher levels of depression and disability were found in the group with diagnostic uncertainty, but levels of pain intensity did not differ between the groups. Although the methodology does not provide information on causality, the results provide evidence for a relationship between diagnostic uncertainty and recall bias for negative health-related stimuli in chronic LBP patients.

    Although diets with high energy density are associated with increased risk of overweight and obesity, it is not known whether such diets are associated with undernutrition. This study assessed the relationship between dietary energy density (ED) and nutritional status of 745 urban 1- to 10-year-old children. Dietary intakes were obtained using food recall and record for two days. Dietary energy density was based on food and caloric beverages. Higher dietary ED was associated with lower intakes of carbohydrate, sugar, vitamins C and D, and calcium but higher fat, fiber, iron, and folate intakes. While intakes of fruits and milk/dairy products decreased, meat, fish, and legume intakes increased with higher dietary ED. Stunting, but not other growth problems, was associated with higher dietary ED. Future studies should confirm the cause-and-effect relationship between higher dietary ED and stunting.

    Full Text Available Abstract Background Obesity is a common pathology with increasing incidence, and is associated with increased mortality and healthcare costs. Several treatment options for obesity are currently available ranging from behavioral modifications to pharmaceutical agents. Many popular dietary supplements claim to enhance weight loss by acting as metabolic stimulators, however direct tests of their effect on metabolism have not been performed. Purpose This work identified the effects popular dietary supplements on metabolic rate and mitochondrial biosynthesis in human skeletal muscle cells. Methods Human rhabdomyosarcoma cells were treated with popular dietary supplements at varied doses for 24 hours. Peroxisome proliferator-activated receptor coactivator 1 alpha (PGC-1α, an important stimulator of mitochondrial biosynthesis, was quantified using quantitative reverse transcriptase polymerase chain reaction (qRT-PCR. Mitochondrial content was measured using flow cytometry confirmed with confocal microscopy. Glycolytic metabolism was quantified by measuring extracellular acidification rate (ECAR and oxidative metabolism was quantified by measuring oxygen consumption rate (OCR. Total relative metabolism was quantified using WST-1 end point assay. Results Treatment of human rhabdomyosarcoma cells with dietary supplements OxyElite Pro (OEP or Cellucore HD (CHD induced PGC-1α leading to significantly increased mitochondrial content. Glycolytic and oxidative capacities were also significantly increased following treatment with OEP or CHD. Conclusion This is the first work to identify metabolic adaptations in muscle cells following treatment with popular dietary supplements including enhanced mitochondrial biosynthesis, and glycolytic, oxidative and total metabolism.

    Full Text Available The study investigates the types of coherence relations adults and children can recall after having read a text. We discerned content and epistemic relations (Dancygier, 1998; Sweetser, 1990. Content relations express relations between events in reality. Epistemic relations typically express relations between states of thinking (premise-conclusion relations. The relations between the two parts of a content or epistemic relation is often made explicit by means of connectives. The differences between these types of sentences have been shown in different areas (e.g., reasoning, clause integration, acquisition. However, no clear results could be reached as for recall of these relations and the interaction with connectives. We aim to clarify this debate by means of an experiment involving 539 participants. The experiment revealed that the difficulty associated with epistemic relations decreases as participants get older. Interestingly, connectives play a larger role in participants' ability to recall epistemic compared to content relations.

    In an initial study, differences in learning and immediate recall were observed for groups of young and aged subjects on several measures. Retest date showed some differential loss for aged subjects after 1 week. Conclusions regarding long-term retention per se were not possible due to the nature of the design. In a second study, additional aged and young groups of subjects were run under delayed recall conditions. The data from these two groups were combined with data from the first study, with care taken to match subjects on a number of variables (health, education, intelligence). The results showed age-related differences for measures of learning and immediate recall but not for delayed 1 week retention.

  20. Using pictographs to enhance recall of spoken medical instructions II.

    2001-06-01

    The first study in this series [Houts PS, Bachrach R, Witmer JT, Tringali CA, Bucher JA, Localio RA. Patient Educ. Couns. 1998;35:83-8] found that recall of spoken medical instructions averaged 14% but that, when pictographs (drawings representing the instructions) accompanied the spoken instructions and were present during recall, 85% of medical instructions were remembered correctly. Those findings suggested that spoken instructions plus pictographs may be a way to give people with low literacy skills access to medical information that is normally available only in written form. However, there were three important limitations to that study: (1) the subjects were literate and perhaps literate people remember pictograph meanings better than people with low literacy skills; (2) only short term recall was tested and, for medical information to be useful clinically, it must be remembered for significant periods of time and (3) a maximum of 50 instructions were shown in pictographs, whereas managing complex illnesses may require remembering several hundred instructions. This study addresses those limitations by investigating 4-week recall of 236 medical instructions accompanied by pictographs by people with low literacy skills. Subjects were 21 adult clients of an inner city job training program who had less than fifth grade reading skills. Results showed 85% mean correct recall of pictograph meanings immediately after training (range from 63 to 99%) and 71% after 4 weeks (range from 33 to 94%). These results indicate that people with low literacy skills can, with the help of pictographs, recall large amounts of medical information for significant periods of time. The impact of pictographs on symptom management and patient quality of life remains to be studied.

    Full Text Available Background: the study of dietary patterns in adolescence becomes of great importance because at this stage individuals acquired eating habits that they will keep throughout their lives. These habits, if not adequate, may increase the risk of chronic diseases in adult ages. Objective: To determine nutritional patterns of eighth grade students and their impact on dietary adequacy. Methods: descriptive study including a universe integrated by all eight grade students in the 5 de Septiembre Junior High School of Cienfuegos. Through simple random sampling, 59 teenagers were selected to be administered two surveys: one on food preferences and another one on a recall of their meals in the last 24 hours. The surveys were prepared by the Institute of Nutrition and Food Hygiene. Results: students preferred fried and sugary foods; only 3.38% received the recommended iron intake; 49, 15% of children received more than 60% of energy from carbohydrates and 59.32% received low amounts of proteins. Conclusions: There are still gaps in these students' nutritional behavior. The major concerning points are the low energy intake and the fact that it is mainly based on carbohydrates, while the deficit in proteins intake, iron and fat has reached a critical point in more than half of our patients.Fundamento: el estudio del patrón alimentario en la adolescencia es de gran importancia ya que en esta etapa se adquieren hábitos alimentarios que se mantendrán toda la vida y que pueden aumentar el riesgo de padecer enfermedades crónicas en la adultez.

    2013-01-01

    In eye movement desensitization and reprocessing (EMDR), a treatment for post-traumatic stress disorder (PTSD), patients make eye movements (EM) during trauma recall. Earlier experimental studies found that EM during recall reduces memory vividness during future recalls, and this was taken as laboratory support for the underlying mechanism of EMDR. However, reduced vividness was assessed with self-reports that may be affected by demand characteristics. We tested whether recall+EM also reduces memory vividness on a behavioural reaction time (RT) task. Undergraduates (N=32) encoded two pictures, recalled them, and rated their vividness. In the EM group, one of the pictures was recalled again while making EM. In the no-EM group one of the pictures was recalled without EM. Then fragments from both the recalled and non-recalled pictures, and new fragments were presented and participants rated whether these were (or were not) seen before. Both pictures were rated again for vividness. In the EM group, self-rated vividness of the recalled+EM picture decreased, relative to the non-recalled picture. In the no-EM group there was no difference between the recalled versus non-recalled picture. The RT task showed the same pattern. Reduction of memory vividness due to recall+EM is also evident from non-self-report data.

    Full Text Available AIM: The purpose of this study was to report obesity status and identify any dietary substances that may be related to obesity in healthy school children from Northern Greece. METHODS: Four hundred and twenty-five (n = 425 children were randomly selected to participate in the study. A 24-h recall of three days (two weekdays and one weekend day was used to analyze the dietary data of the subjects. RESULTS: Out of 425 subjects, 146 (34.3% of them were found to be overweight and obese. Energy, protein, carbohydrate and thiamin intake was statistically positively correlated with obesity while dietary iron intake was statistically negatively correlated with obesity. Multivariate logistic regression analysis showed that the children with dietary iron deficiency were 1.128 (95% CI: 0.002, 0.161 P < 0.031 times more likely of being obese compared to the normal group after adjustment for energy intake. CONCLUSIONS: Although most of the dietary intakes of our subjects were adequate, special consideration should be given to energy, carbohydrate, protein, and sugar and iron intake especially and its relation to obesity. Furthermore, additional studies are required to investigate any possible relation of low dietary iron consumption and obesity.

    Full Text Available Introduction. The aim of the study was to assess the intake of vitamins and minerals from the food ration and levels recorded after synthetic supplementation in patients following a gluten-free diet. Material and methods. The study included a cohort of 25 individuals aged 20-54. Nutrient intakes were assessed based on a 24-hour diet recall interview and an original questionnaire prepared by the authors specifically for this study. Anthropometric measurements were recorded in order to assess the nutritional status of the patients. Results and discussion. A low energy intake and an excessive share of fat were observed in daily food rations of coeliac disease patients. Uptake of most minerals with the diet was too low, while that of vitamins too high. Most participants declared the administration of supplements, which greatly contributed to the coverage of requirements for these nutrients. Conclusions. It was observed that the administered supplementation was frequently unjustifi ed, which led to the allowances being considerably exceeded for many vitamins and minerals.
