We surveyed customers in a hospital cafeteria in Boston, Massachusetts before and after implementation of traffic light food labeling to determine the effect of labels on customers' awareness and purchase of healthy foods. Cafeteria items were identified as red (unhealthy), yellow (less healthy), or green (healthy). Customers were interviewed before (N=166) and after (N=223) labeling was implemented. Each respondent was linked to cash register data to determine the proportion of red, yellow, and green items purchased. Data were collected from February-April 2010. We compared responses to survey questions and mean proportion of red, yellow, and green items per transaction between customers interviewed during baseline and customers interviewed during the intervention. Survey response rate was 60%. Comparing responses during labeling intervention to baseline, more respondents identified health/nutrition as an important factor in their purchase (61% vs. 46%, p=0.004) and reported looking at nutrition information (33% vs. 15%, p<0.001). Respondents who noticed labels during the intervention and reported that labels influenced their purchases were more likely to purchase healthier items than respondents who did not notice labels (p<0.001 for both). Traffic light food labels prompted individuals to consider their health and to make healthier choices at point-of-purchase. © 2013.

We used a change detection method to evaluate attentional prioritization of nutrition information that appears in the traditional “Nutrition Facts Panel” and in front-of-pack nutrition labels. Results provide compelling evidence that front-of-pack labels attract attention more readily than the Nutrition Facts Panel, even when participants are not specifically tasked with searching for nutrition information. Further, color-coding the relative nutritional value of key nutrients within the front-of-pack label resulted in increased attentional prioritization of nutrition information, but coding using facial icons did not significantly increase attention to the label. Finally, the general pattern of attentional prioritization across front-of-pack designs was consistent across a diverse sample of participants. Our results indicate that color-coded, front-of-pack nutrition labels increase attention to the nutrition information of packaged food, a finding that has implications for current policy discussions regarding labeling change.

Statement of Problem: Positive identification of the dead after accidents and disasters through labeled dentures plays a key role in forensic scenario. A number of denture labeling methods are available, and studies evaluating their reliability under drastic conditions are vital. Aim: This study was conducted to evaluate the reliability of QR (Quick Response) Code labeled at various depths in heat-cured acrylic blocks after acid treatment, heat treatment (burns), and fracture in forensics. It was an in vitro study. Materials and Methods: This study included 160 specimens of heat-cured acrylic blocks (1.8 cm × 1.8 cm) and these were divided into 4 groups (40 samples per group). QR Codes were incorporated in the samples using clear acrylic sheet and they were assessed for reliability under various depths, acid, heat, and fracture. Data were analyzed using Chi-square test, test of proportion. Results: The QR Code inclusion technique was reliable under various depths of acrylic sheet, acid (sulfuric acid 99%, hydrochloric acid 40%) and heat (up to 370°C). Results were variable with fracture of QR Code labeled acrylic blocks. Conclusion: Within the limitations of the study, by analyzing the results, it was clearly indicated that the QR Code technique was reliable under various depths of acrylic sheet, acid, and heat (370°C). Effectiveness varied in fracture and depended on the level of distortion. This study thus suggests that QR Code is an effective and simpler denture labeling method. PMID:28123284

Infrared detection without specialized infrared receptors in the bloodsucking bug Rhodnius prolixus.

Bloodsucking bugs use infrared radiation (IR) for locating warm-blooded hosts and are able to differentiate between infrared and temperature (T) stimuli. This paper is concerned with the neuronal coding of IR in the bug Rhodnius prolixus. Data obtained are from the warm cells in the peg-in-pit sensilla (PSw cells) and in the tapered hairs (THw cells). Both warm cells responded to oscillating changes in air T and IR with oscillations in their discharge rates. The PSw cells produced stronger responses to T oscillations than the THw cells. Oscillations in IR did the reverse: they stimulated the latter more strongly than the former. The reversal in the relative excitability of the two warm cell types provides a criterion to distinguish between changes in T and IR. The existence of strongly responsive warm cells for one or the other stimulus in a paired comparison is the distinguishing feature of a "combinatory coding" mechanism. This mechanism enables the information provided by the difference or the ratio between the response magnitudes of both cell types to be utilized by the nervous system in the neural code for T and IR. These two coding parameters remained constant, although response strength changed when the oscillation period was altered. To discriminate between changes in T and IR, two things are important: which sensory cell responded to either stimulus and how strong was the response. The label warm or infrared cell may indicate its classification, but the functions are only given in the context of activity produced in parallel sensory cells.

To develop an internationally agreed terminology for describing ocular tissue grafts to improve the accuracy and reliability of information transfer, to enhance tissue traceability, and to facilitate the gathering of comparative global activity data, including denominator data for use in biovigilance analyses. ICCBBA, the international standards organization for terminology, coding, and labeling of blood, cells, and tissues, approached the major Eye Bank Associations to form an expert advisory group. The group met by regular conference calls to develop a standard terminology, which was released for public consultation and amended accordingly. The terminology uses broad definitions (Classes) with modifying characteristics (Attributes) to define each ocular tissue product. The terminology may be used within the ISBT 128 system to label tissue products with standardized bar codes enabling the electronic capture of critical data in the collection, processing, and distribution of tissues. Guidance on coding and labeling has also been developed. The development of a standard terminology for ocular tissue marks an important step for improving traceability and reducing the risk of mistakes due to transcription errors. ISBT 128 computer codes have been assigned and may now be used to label ocular tissues. Eye banks are encouraged to adopt this standard terminology and move toward full implementation of ISBT 128 nomenclature, coding, and labeling.

This study examined nurses' adherence to policies regarding needleless connector changes using a novel, day-of-the-week, color-coded label compared with usual care that relied on electronic medical record (EMR) documentation. This was a prospective, comparative study. The study was performed on 4 medical-surgical units in a seasonally fluctuating, 715-bed healthcare system composed of 2 community hospitals. Convenience sample was composed of adults with central lines hospitalized for 4 or more days. At 4-day intervals, investigators observed bedside label use and EMR needleless connector change documentation. Control patients received standard care-needleless connector change with associated documentation in the EMR. Intervention patients, in addition to standard care, had a day-of-the-week, color-coded label placed on each needleless connector. To account for clustering within unit, multinomial logistic regression models using survey sampling methodology were used to conduct Wald χ tests. A multinominal odds ratio and 95% confidence interval (CI) provided an estimate of using labels that were provided on units relative to usual care documentation of needleless connector change in the EMR. In 335 central line observations, the units with labels (n = 205) had a 321% increase rate of documentation of needleless connector change in the EMR (odds ratio, 4.21; 95% CI, 1.76-10.10; P = .003) compared with the usual care control patients. For units with labels, when labels were present, placement of labels on needleless connectors increased the odds that nurses documented connector changes per policy (4.72; 95% CI, 2.02, 10.98; P = .003). Day-of-the-week, color-coded labels cued nurses to document central line needleless connector change in the EMR, which increased adherence to the needleless connector change policy. Providing day-of-the-week, color-coded needleless connector labels increased EMR documentation of timely needleless connector changes. Timely needleless connector changes may lower the incidence of central line-associated bloodstream infection.

Effects of labeling and interpersonal contact upon attitudes towards schizophrenia: implications for reducing mental illness stigma in urban China.

As mental illness stigma contributes to poor outcomes for schizophrenia in China, locating strategies to reduce public stigma is imperative. It is currently unknown whether diagnostic labeling and contact with different help-seeking sources increase or decrease public stigma in China. Further, it remains unresolved whether prior personal contact acts to reduce stigma in this context. Advancing understanding of these processes may facilitate stigma-reduction strategies. We administered an experimental vignette randomly assigning one of four labeling conditions to respondents to assess social distance towards a psychotic vignette individual in a sample of 160 Northern, urban Chinese community respondents. As expected, respondents given a "non-psychiatric, indigenous label" + "lay help-seeking" condition endorsed the least social distance. Unexpectedly, the labeling condition with a "psychiatric diagnostic label" + "lay help-seeking" condition elicited the greatest social distance. Unlike Western studies, personal contact did not independently decrease community stigma. However, prior contact reduced social distance to a greater extent in the labeling condition with a "non-psychiatric, indigenous label" + "lay help-seeking" condition when compared with all other labeling conditions. The results indicate that cultural idioms do provide some protection from stigma, but only among respondents who are already familiar with what mental illness is. Our finding that the condition that depicted untreated psychosis elicited the greatest amount of stigma, while the "treated psychosis" condition was viewed relatively benignly in China, suggests that improved access to mental health services in urban China has the potential to decrease public stigma via labeling mechanisms.

...The Coast Guard proposes to remove references to type codes in its regulations on the carriage and labeling of Coast Guard-approved personal flotation devices (PFDs). PFD type codes are unique to Coast Guard approval and are not well understood by the public. Removing these type codes from our regulations would facilitate future incorporation by reference of new industry consensus standards for PFD labeling that will more effectively convey safety information, and is a step toward harmonization of our regulations with PFD requirements in Canada and in other countries.

2014-04-01

In the U.S. media, unauthorized immigrants are often interchangeably referred to as "illegal aliens," "illegal immigrants," and undocumented immigrants." In spite of formal equivalence, these terms carry different connotations, but the effects of these labels on people's attitudes toward immigrants are not well documented. In this replication study, 274 undergraduate students in psychology responded to one of three randomly distributed versions of a 20-item scale measuring attitudes toward unauthorized immigration. The items in the three scale versions varyingly referred to immigrants using the three terms. Results showed differences in attitudes toward unauthorized immigration between all experimental conditions. The label "illegal immigrants" yielded significantly less positive attitudes compared to the label "undocumented immigrants," and respondents exposed to the label "illegal aliens" showed the most positive attitudes. Furthermore, the effects of the experimental conditions were not moderated by the respondents' patriotism, sex, or own immigrant background.

The aim of this study was to determine the compliance status of product labels regarding Article 9 of the International Code on Marketing of Breast-milk Substitutes (the Code) in Denizli province, Turkey. A cross-sectional study design was employed to determine the compliance status. The product labels were obtained from a convenience sample of five supermarkets, one store and 5 pharmacies in the City centre and district of Honaz. Using a data collection form prepared by previously published studies, data were collected between July 26, 2010 and August 06, 2010. Data collection form included 13 criteria. In addition, we checked the boxes for the availability of a Turkish written label. Forty product labels of 7 companies were reached and evaluated. These products consisted of 83.0% of the products marketed by these companies in Turkey. Thirty seven (92.5%) of the labels violated Article 9 of the Code in terms of one or more criteria. Thirty four (85.0%) of the labels had photos or pictures idealizing the use of infant formula. Nine (22.5%) had a photo, a picture or any representation of an infant, and five (12.5%) had text which idealize the use of infant formula or discouraging breastfeeding. Eight (20%) did not state that breastfeeding is the best. Four (10%) had a term such as 'similar to breast milk or human milk'. In conclusion, the majority of the product labels of breast milk substitutes marketed in our country violate the Code. It is appropriate that the Turkish Ministry of Health, medical organizations, companies, and NGOs work more actively to increase awareness of this issue.

In this paper the design, fabrication and experimental characterization of an spectral amplitude coded (SAC) optical label swapper monolithically integrated on Indium Phosphide (InP) is presented. The device has a footprint of 4.8x1.5 mm2 and is able to perform label swapping operations required in SAC at a speed of 155 Mbps. The device was manufactured in InP using a multiple purpose generic integration scheme. Compared to previous SAC label swapper demonstrations, using discrete component assembly, this label swapper chip operates two order of magnitudes faster.

Breadth of tuning in taste afferent neurons varies with stimulus strength

Wu, An; Dvoryanchikov, Gennady; Pereira, Elizabeth; Chaudhari, Nirupa; Roper, Stephen D.

2015-01-01

Gustatory stimuli are detected by taste buds and transmitted to the hindbrain via sensory afferent neurons. Whether each taste quality (sweet, bitter and so on) is encoded by separate neurons (‘labelled lines') remains controversial. We used mice expressing GCaMP3 in geniculate ganglion sensory neurons to investigate taste-evoked activity. Using confocal calcium imaging, we recorded responses to oral stimulation with prototypic taste stimuli. Up to 69% of neurons respond to multiple tastants. Moreover, neurons tuned to a single taste quality at low concentration become more broadly tuned when stimuli are presented at higher concentration. Responses to sucrose and monosodium glutamate are most related. Although mice prefer dilute NaCl solutions and avoid concentrated NaCl, we found no evidence for two separate populations of sensory neurons that encode this distinction. Altogether, our data suggest that taste is encoded by activity in patterns of peripheral sensory neurons and challenge the notion of strict labelled line coding. PMID:26373451

Spontaneous labelling and stigma associated with clinical characteristics of peers 'at-risk' for psychosis.

The public health benefits of utilizing an 'at-risk for psychosis' designation are tempered by concerns about stigma. It is therefore of interest to examine whether symptoms associated with this designation might spontaneously induce labels associated with a psychotic disorder, other non-psychotic disorders or non-psychiatric labels. This pilot study explored the labels associated with characteristics of 'high risk for psychosis' and the corresponding stigma level. A vignette describing an identical character, followed by a series of questions about stigmatizing attitudes towards the vignette character, was administered in the present investigation. The results indicated that even though most young people (59%) did not spontaneously label the vignette character with psychotic-like diagnostic labels, the single most frequent label provided was 'paranoid/a'. When such labelling, that is, strongly tied to psychosis, occurred, respondents exhibited stronger stigmatizing attributions of fear compared to those indicating non-psychiatric labels (e.g. 'weird'). These results suggest that the majority of respondents did not endorse diagnostic labels spontaneously, thus signaling that stigma in the majority of cases would not naturalistically be elicited. However, a segment of respondents evidenced stigma simply from behavioural changes manifested by individuals exhibiting signs of psychosis, independent of diagnosis. Implications for reducing any stigma associated with an 'at-risk for psychosis' designation are discussed. © 2013 Wiley Publishing Asia Pty Ltd.

Study on multiple-hops performance of MOOC sequences-based optical labels for OPS networks

Zhang, Chongfu; Qiu, Kun; Ma, Chunli

2009-11-01

In this paper, we utilize a new study method that is under independent case of multiple optical orthogonal codes to derive the probability function of MOOCS-OPS networks, discuss the performance characteristics for a variety of parameters, and compare some characteristics of the system employed by single optical orthogonal code or multiple optical orthogonal codes sequences-based optical labels. The performance of the system is also calculated, and our results verify that the method is effective. Additionally it is found that performance of MOOCS-OPS networks would, negatively, be worsened, compared with single optical orthogonal code-based optical label for optical packet switching (SOOC-OPS); however, MOOCS-OPS networks can greatly enlarge the scalability of optical packet switching networks.

Effective standardization of medical device labels requires objective study of varied designs. Insufficient empirical evidence exists regarding how practitioners utilize and view labeling. Measure the effect of graphic elements (boxing information, grouping information, symbol use and color-coding) to optimize a label for comparison with those typical of commercial medical devices. Participants viewed 54 trials on a computer screen. Trials were comprised of two labels that were identical with regard to graphics, but differed in one aspect of information (e.g., one had latex, the other did not). Participants were instructed to select the label along a given criteria (e.g., latex containing) as quickly as possible. Dependent variables were binary (correct selection) and continuous (time to correct selection). Eighty-nine healthcare professionals were recruited at Association of Surgical Technologists (AST) conferences, and using a targeted e-mail of AST members. Symbol presence, color coding and grouping critical pieces of information all significantly improved selection rates and sped time to correct selection (α = 0.05). Conversely, when critical information was graphically boxed, probability of correct selection and time to selection were impaired (α = 0.05). Subsequently, responses from trials containing optimal treatments (color coded, critical information grouped with symbols) were compared to two labels created based on a review of those commercially available. Optimal labels yielded a significant positive benefit regarding the probability of correct choice ((P<0.0001) LSM; UCL, LCL: 97.3%; 98.4%, 95.5%)), as compared to the two labels we created based on commercial designs (92.0%; 94.7%, 87.9% and 89.8%; 93.0%, 85.3%) and time to selection. Our study provides data regarding design factors, namely: color coding, symbol use and grouping of critical information that can be used to significantly enhance the performance of medical device labels.

2015-10-01

The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P < 0.001). All respondents reported that all six items (bold font, font color, box frame, warning statement, front label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers.

A Low-Storage-Consumption XML Labeling Method for Efficient Structural Information Extraction

NASA Astrophysics Data System (ADS)

Liang, Wenxin; Takahashi, Akihiro; Yokota, Haruo

Recently, labeling methods to extract and reconstruct the structural information of XML data, which are important for many applications such as XPath query and keyword search, are becoming more attractive. To achieve efficient structural information extraction, in this paper we propose C-DO-VLEI code, a novel update-friendly bit-vector encoding scheme, based on register-length bit operations combining with the properties of Dewey Order numbers, which cannot be implemented in other relevant existing schemes such as ORDPATH. Meanwhile, the proposed method also achieves lower storage consumption because it does not require either prefix schema or any reserved codes for node insertion. We performed experiments to evaluate and compare the performance and storage consumption of the proposed method with those of the ORDPATH method. Experimental results show that the execution times for extracting depth information and parent node labels using the C-DO-VLEI code are about 25% and 15% less, respectively, and the average label size using the C-DO-VLEI code is about 24% smaller, comparing with ORDPATH.

Stewart, Derek; Rouf, Abdul; Snaith, Ailsa; Elliott, Kathleen; Helms, Peter J; McLay, James S

2007-01-01

What is already known about this subject There are increasing concerns about the safety and efficacy of paediatric off-label medicines. In the UK, each year 26% of children receive an off-label prescription from their general practitioner. The community pharmacist is the final and key professional in the chain, with the responsibility to ensure that medicines are both prescribed and dispensed appropriately. What this study adds The majority of community pharmacists are aware of off-label prescribing, but through work experience rather than undergraduate or postgraduate training or professional development. Community pharmacists, like UK general practitioners, underestimate the levels of paediatric off-label prescribing, and appear unclear as to the most common reasons for a prescription being off label. Most community pharmacists stated that they should inform the prescriber that a medicine was off label; however, when given specific practical examples, less than half would actually appear to do so. The majority of community pharmacists have been asked by the public to sell over-the-counter medicines for paediatric off-label use. Aim To identify community pharmacist experiences of, and attitudes towards paediatric off-label prescribing. Methods A prospective questionnaire-based study, with a 21-item questionnaire issued to 1500 randomly selected community pharmacies throughout the UK during 2005 on three separate occasions. Results Four hundred and eighty-two (32.1%) completed questionnaires were returned. Over 70% of respondents were familiar with the concept of off-label prescribing, primarily through dispensing experience rather than education, although only 40% were aware of having dispensed a paediatric off-label prescription within the previous month. The reasons given for a prescription being off label were younger age than recommended (84.6%, 297/351), primarily for antihistamines, analgesics and β2-agonists, and higher (73.9%, 229/310) or lower than (41%, 103/258) recommended dose, primarily antibiotics and analgesics. Over 60% of respondents had been asked by the public to sell paediatric over-the-counter medicines, such as antihistamines, analgesics and steroid preparations for off-label use. The majority of respondents used the British National Formulary or the Pack Insert rather than specialist formularies or guidelines as a source of specialist paediatric information. Although 78% of respondents believed they had a responsibility to inform the prescriber that a medicine was off label, only 66% believed that they had a similar responsibility to inform parents. Conclusion The community pharmacists who responded to this questionnaire appear to be aware of and concerned by the issues which surround paediatric off-label prescribing. Despite this, most gained relevant knowledge through work experience rather than undergraduate or postgraduate training or professional development. PMID:17324238

Simplifying healthful choices: a qualitative study of a physical activity based nutrition label format

PubMed Central

2013-01-01

Background This study used focus groups to pilot and evaluate a new nutrition label format and refine the label design. Physical activity equivalent labels present calorie information in terms of the amount of physical activity that would be required to expend the calories in a specified food item. Methods Three focus groups with a total of twenty participants discussed food choices and nutrition labeling. They provided information on comprehension, usability and acceptability of the label. A systematic coding process was used to apply descriptive codes to the data and to identify emerging themes and attitudes. Results Participants in all three groups were able to comprehend the label format. Discussion about label format focused on issues including gender of the depicted figure, physical fitness of the figure, preference for walking or running labels, and preference for information in miles or minutes. Feedback from earlier focus groups was used to refine the labels in an iterative process. Conclusions In contrast to calorie labels, participants shown physical activity labels asked and answered, “How does this label apply to me?” This shift toward personalized understanding may indicate that physical activity labels offer an advantage over currently available nutrition labels.

This study was undertaken to assess the people's self-reported reading of medicine labels and its associated factors and to assess the sources of information about medicines among general public. A cross-sectional study was carried out among general public in the State of Penang, Malaysia. A total of 888 participants were conveniently selected and completed the survey. A self-administered questionnaire was used to obtain the data from all the participants. Most of the participants (74.2%) reported that they have adequate information about medicines provided on their medicine labels. In addition, 86.9% of them reported that they read their medicine's label for the directions of usage and 84.3% for the dosage instruction. However, 42.1% of the participants do not read their medicine's label for the active ingredients, and 33% of them do not read their medicine's label for the safety information. In addition, 36.5% of the respondents did not read the label of medicine for the symptoms which can be used for. However, females, Malay respondents, and higher education level (college/university) were more likely to self-reported the reading medicine's label. Females were more likely to read the labels of medicines compared with males (OR = 1.6, 95% CI 1.20-2.13, P  = .001). The reading of medicine labels was predicted by females, Malay respondents, and higher educated people. Health educational programs are needed to clarify label's information that can help in concept of patient safety.

Medication errors are a significant cause of severe healthcare-associated complications. In December 2006, the French Health Products Agency (Afssaps) has issued a protocol to harmonise labeling of injectable drugs vials. In 2007, a first change was launched for four drugs and was followed in 2008-2009 by a second wave concerning 42 active drugs. The present study describes how healthcare professionals have perceived this change and their overall appreciation of the drug harmonisation programme. A survey using an electronic questionnaire was distributed to medical and non-medical professionals in anaesthesia and intensive care and pharmacists in a representative sample of 200 French hospitals. The harmonisation procedure was felt as being overall satisfactory by 53% of professionals who had responded but it was recognised that the new procedure is associated with improved readability and understanding of drug dosage. The use of colour coding was also well accepted by the personnel of clinical units. Respondents expressed significant criticisms regarding both the communication plan and the way the plan was implemented locally in hospitals. Old and new labeling coexisted in 66% of responding hospitals and many respondents described being aware of errors or near-misses that were considered related to the transition. For many important topics, pharmacists had views that were significantly different from clinicians. This national survey describing the perception of healthcare professionals regarding the new harmonisation procedure for injectable drugs highlighted some progress but also a number of deficiencies, notably regarding communication and implementation of the change in clinical units. This survey will be used by the French Health Products Agency to improve future steps of the long-lasting campaign against medication errors.

Implementation of a Post-Code Pause: Extending Post-Event Debriefing to Include Silence.

PubMed

Copeland, Darcy; Liska, Heather

2016-01-01

This project arose out of a need to address two issues at our hospital: we lacked a formal debriefing process for code/trauma events and the emergency department wanted to address the psychological and spiritual needs of code/trauma responders. We developed a debriefing process for code/trauma events that intentionally included mechanisms to facilitate recognition, acknowledgment, and, when needed, responses to the psychological and spiritual needs of responders. A post-code pause process was implemented in the emergency department with the aims of standardizing a debriefing process, encouraging a supportive team-based culture, improving transition back to "normal" activities after responding to code/trauma events, and providing responders an opportunity to express reverence for patients involved in code/trauma events. The post-code pause process incorporates a moment of silence and the addition of two simple questions to a traditional operational debrief. Implementation of post-code pauses was feasible despite the fast paced nature of the department. At the end of the 1-year pilot period, staff members reported increases in feeling supported by peers and leaders, their ability to pay homage to patients, and having time to regroup prior to returning to their assignment. There was a decrease in the number of respondents reporting having thoughts or feelings associated with the event within 24 hr. The pauses create a mechanism for operational team debriefing, provide an opportunity for staff members to honor their work and their patients, and support an environment in which the psychological and spiritual effects of responding to code/trauma events can be acknowledged.

In this paper, the tunable multiple optical orthogonal codes sequences (MOOCS)-based optical label for optical packet switching (OPS) (MOOCS-OPS) is experimentally demonstrated for the first time. The tunable MOOCS-based optical label is performed by using fiber Bragg grating (FBG)-based optical en/decoders group and optical switches configured by using Field Programmable Gate Array (FPGA), and the optical label is erased by using Semiconductor Optical Amplifier (SOA). Some waveforms of the MOOCS-based optical label, optical packet including the MOOCS-based optical label and the payloads are obtained, the switching control mechanism and the switching matrix are discussed, the bit error rate (BER) performance of this system is also studied. These experimental results show that the tunable MOOCS-OPS scheme is effective.

BACKGROUND/OBJECTIVES The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. SUBJECTS/METHODS A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. RESULTS The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P < 0.001). All respondents reported that all six items (bold font, font color, box frame, warning statement, front label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. CONCLUSIONS An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers. PMID:26425282

2010-10-01

Based on in-store observations in three major UK retailers, in-store interviews (2019) and questionnaires filled out at home and returned (921), use of nutrition information on food labels and its understanding were investigated. Respondents' nutrition knowledge was also measured, using a comprehensive instrument covering knowledge of expert recommendations, nutrient content in different food products, and calorie content in different food products. Across six product categories, 27% of shoppers were found to have looked at nutrition information on the label, with guideline daily amount (GDA) labels and the nutrition grid/table as the main sources consulted. Respondents' understanding of major front-of-pack nutrition labels was measured using a variety of tasks dealing with conceptual understanding, substantial understanding and health inferences. Understanding was high, with up to 87.5% of respondents being able to identify the healthiest product in a set of three. Differences between level of understanding and level of usage are explained by different causal mechanisms. Regression analysis showed that usage is mainly related to interest in healthy eating, whereas understanding of nutrition information on food labels is mainly related to nutrition knowledge. Both are in turn affected by demographic variables, but in different ways.

Interpretive front-of-pack nutrition labels. Comparing competing recommendations.

PubMed

Maubach, Ninya; Hoek, Janet; Mather, Damien

Many stakeholders support introducing an interpretive front-of-pack (FOP) nutrition label, but disagree over the form it should take. In late 2012, an expert working group established by the New Zealand government recommended the adoption of an untested summary rating system: a Star label. This study used a best-worst scaling choice experiment to estimate how labels featuring the new Star rating, the Multiple Traffic Light (MTL), Daily Intake Guide (DIG), and a no-FOP control affected consumers' choice behaviours and product perceptions. Nutrient-content and health claims were included in the design. We also assessed whether respondents who used more or less information during the choice tasks differed in their selection patterns. Overall, while respondents made broadly similar choices with respect to the MTL and Star labels, the MTL format had a significantly greater impact on depressing preference as a food's nutritional profile became less healthy. Health claims increased rankings of less nutritious options, though this effect was less pronounced when the products featured an MTL. Further, respondents were best able to differentiate products' healthiness with MTL labels. The proposed summary Stars system had less effect on choice patterns than an MTL label and our findings highlight the need for policy makers to ensure that decisions to introduce FOP labels are underpinned by robust research evidence. These results suggest that the proposed summary Stars system will have less effect on shifting food choice patterns than interpretive FOP nutrition label featuring traffic light ratings.

Relative and accurate measurement of protein abundance using 15N stable isotope labeling in Arabidopsis (SILIA).

PubMed

Guo, Guangyu; Li, Ning

2011-07-01

In the quantitative proteomic studies, numerous in vitro and in vivo peptide labeling strategies have been successfully applied to measure differentially regulated protein and peptide abundance. These approaches have been proven to be versatile and repeatable in biological discoveries. (15)N metabolic labeling is one of these widely adopted and economical methods. However, due to the differential incorporation rates of (15)N or (14)N, the labeling results produce imperfectly matched isotopic envelopes between the heavy and light nitrogen-labeled peptides. In the present study, we have modified the solid Arabidopsis growth medium to standardize the (15)N supply, which led to a uniform incorporation of (15)N into the whole plant protein complement. The incorporation rate (97.43±0.11%) of (15)N into (15)N-coded peptides was determined by correlating the intensities of peptide ions with the labeling efficiencies according to Gaussian distribution. The resulting actual incorporation rate (97.44%) and natural abundance of (15)N/(14)N-coded peptides are used to re-calculate the intensities of isotopic envelopes of differentially labeled peptides, respectively. A modified (15)N/(14)N stable isotope labeling strategy, SILIA, is assessed and the results demonstrate that this approach is able to differentiate the fold change in protein abundance down to 10%. The machine dynamic range limitation and purification step will make the precursor ion ratio deriving from the actual ratio fold change. It is suggested that the differentially mixed (15)N-coded and (14)N-coded plant protein samples that are used to establish the protein abundance standard curve should be prepared following a similar protein isolation protocol used to isolate the proteins to be quantitated.

Affect labeling enhances exposure effectiveness for public speaking anxiety.

PubMed

Niles, Andrea N; Craske, Michelle G; Lieberman, Matthew D; Hur, Christopher

2015-05-01

Exposure is an effective treatment for anxiety but many patients do not respond fully. Affect labeling (labeling emotional experience) attenuates emotional responding. The current project examined whether affect labeling enhances exposure effectiveness in participants with public speaking anxiety. Participants were randomized to exposure with or without affect labeling. Physiological arousal and self-reported fear were assessed before and after exposure and compared between groups. Consistent with hypotheses, participants assigned to Affect Labeling, especially those who used more labels during exposure, showed greater reduction in physiological activation than Control participants. No effect was found for self-report measures. Also, greater emotion regulation deficits at baseline predicted more benefit in physiological arousal from exposure combined with affect labeling than exposure alone. The current research provides evidence that behavioral strategies that target prefrontal-amygdala circuitry can improve treatment effectiveness for anxiety and these effects are particularly pronounced for patients with the greatest deficits in emotion regulation.

2015-01-01

OBJECTIVES: Menu labels displaying food energy in physical activity calorie equivalents (PACE) is a possible strategy to encourage ordering meals with fewer calories and promoting physical activity. Potential effects of such labeling for children have never been examined. METHODS: We conducted a national survey of 1000 parents randomized to 1 of 4 fast food menus: no labels, calories only, calories plus minutes, or calories plus miles needed to walk to burn the calories. Respondents were asked to imagine they were in a fast food restaurant and place an order for their child. At the survey’s conclusion, all respondents were shown a calorie-only label and both PACE labels and asked to rate the likelihood each label would influence them to encourage their child to exercise. RESULTS: We excluded respondents whose meals totaled 0 calories or >4000 calories, leaving 823 parents in the analysis. The mean age of the child for whom the meal was “ordered” was 9.5 years. Parents whose menus displayed no label ordered an average of 1294 calories, whereas those shown calories only, calories plus minutes, or calories plus miles ordered 1066, 1060, and 1099 calories, respectively (P = .0001). Only 20% of parents reported that calories-only labeling would be “very likely” to prompt them to encourage their children to exercise versus 38% for calories plus minutes (P < .0001) and 37% for calories plus miles (P < .0001). CONCLUSIONS: PACE labeling may influence parents’ decisions on what fast food items to order for their children and encourage them to get their children to exercise. PMID:25624379

The nematode Caenorhabditis elegans is an important model organism for biomedical research. We previously described NeuCode stable isotope labeling by amino acids in cell culture (SILAC), a method for accurate proteome quantification with potential for multiplexing beyond the limits of traditional stable isotope labeling by amino acids in cell culture. Here we apply NeuCode SILAC to profile the proteomic and phosphoproteomic response of C. elegans to two potent members of the ascaroside family of nematode pheromones. By consuming labeled E. coli as part of their diet, C. elegans nematodes quickly and easily incorporate the NeuCode heavy lysine isotopologues by the young adult stage. Using this approach, we report, at high confidence, one of the largest proteomic and phosphoproteomic data sets to date in C. elegans: 6596 proteins at a false discovery rate ≤ 1% and 6620 phosphorylation isoforms with localization probability ≥75%. Our data reveal a post-translational signature of pheromone sensing that includes many conserved proteins implicated in longevity and response to stress. PMID:26392051

Drug-laden 3D biodegradable label using QR code for anti-counterfeiting of drugs.

Wiping out counterfeit drugs is a great task for public health care around the world. The boost of these drugs makes treatment to become potentially harmful or even lethal. In this paper, biodegradable drug-laden QR code label for anti-counterfeiting of drugs is proposed that can provide the non-fluorescence recognition and high capacity. It is fabricated by the laser cutting to achieve the roughness over different surface which causes the difference in the gray levels on the translucent material the QR code pattern, and the micro mold process to obtain the drug-laden biodegradable label. We screened biomaterials presenting the relevant conditions and further requirements of the package. The drug-laden microlabel is on the surface of the troches or the bottom of the capsule and can be read by a simple smartphone QR code reader application. Labeling the pill directly and decoding the information successfully means more convenient and simple operation with non-fluorescence and high capacity in contrast to the traditional methods.

Nutritional supplement products: Does the label information influence purchasing decisions for the physically active?

PubMed

Gabriels, Gary; Lambert, Mike

2013-10-02

The increase in sales of nutritional supplement globally can be attributed, in part, to aggressive marketing by manufacturers, rather than because the nutritional supplements have become more effective. Furthermore, the accuracy of the labelling often goes unchallenged. Therefore, any effects of the supplement, may be due to contaminants or adulterants in these products not reflected on the label. A self-administered questionnaire was used to determine how consumers of nutritional supplements acquired information to assist their decision-making processes, when purchasing a product. The study was approved by the University of Cape Town, Faculty of Health Sciences Human Research Ethics Committee. The questionnaire consisted of seven, closed and open-ended questions. The participants were asked to respond to the questions according to a defined list of statements. A total of 259 participants completed and returned questionnaires. The data and processing of the returned questionnaires was captured using Windows-based Microsoft® Office Excel 2003 SP 1 (Excel © 1985-2003 Microsoft Corporation). Statistica Version 10 (copyright © Stat Soft, Inc. 1984-2011) was used to calculate the descriptive statistics. The main finding of the study was that nearly 70% of the respondents who purchased supplements were strongly influenced by container label information that stipulated that the nutritional supplement product is free of banned substances. The second finding was that just over 50% of the respondents attached importance to the quality of the nutritional supplement product information on the container label. The third finding was that about 40% of the respondents were strongly influenced by the ingredients on the labels when they purchased nutritional supplements. This study, (i) identifies short-comings in current labelling information practices, (ii) provides opportunities to improve label and non-label information and communication, and, (iii) presents the case for quality assurance laboratory "screening testing" of declared and undeclared contaminants and/or adulterants, that could have negative consequences to the consumer.

Deep Hashing for Scalable Image Search.

PubMed

Lu, Jiwen; Liong, Venice Erin; Zhou, Jie

2017-05-01

In this paper, we propose a new deep hashing (DH) approach to learn compact binary codes for scalable image search. Unlike most existing binary codes learning methods, which usually seek a single linear projection to map each sample into a binary feature vector, we develop a deep neural network to seek multiple hierarchical non-linear transformations to learn these binary codes, so that the non-linear relationship of samples can be well exploited. Our model is learned under three constraints at the top layer of the developed deep network: 1) the loss between the compact real-valued code and the learned binary vector is minimized, 2) the binary codes distribute evenly on each bit, and 3) different bits are as independent as possible. To further improve the discriminative power of the learned binary codes, we extend DH into supervised DH (SDH) and multi-label SDH by including a discriminative term into the objective function of DH, which simultaneously maximizes the inter-class variations and minimizes the intra-class variations of the learned binary codes with the single-label and multi-label settings, respectively. Extensive experimental results on eight widely used image search data sets show that our proposed methods achieve very competitive results with the state-of-the-arts.

Benzofurazane has been attached to nucleosides and dNTPs, either directly or through an acetylene linker, as a new redox label for electrochemical analysis of nucleotide sequences. Primer extension incorporation of the benzofurazane-modified dNTPs by polymerases has been developed for the construction of labeled oligonucleotide probes. In combination with nitrophenyl and aminophenyl labels, we have successfully developed a three-potential coding of DNA bases and have explored the relevant electrochemical potentials. The combination of benzofurazane and nitrophenyl reducible labels has proved to be excellent for ratiometric analysis of nucleotide sequences and is suitable for bioanalytical applications.

The authors previously reported on a 2-by-2 randomized clinical trial of individual and combined treatment with atomoxetine (ATX) and parent training (PT) for attention-deficit/hyperactivity disorder (ADHD) symptoms and behavioral noncompliance in 128 5- to 14-year-old children with autism spectrum disorder. In the present report, they describe a 24-week extension of treatment responders and nonresponders. One-hundred seventeen participants from the acute trial (91%) entered the extension; 84 of these were in 2 subgroups: "treatment responders" (n = 43) from all 4 groups in the acute trial, seen monthly for 24 weeks, and "placebo nonresponders" (n = 41), treated with open-label ATX for 10 weeks. Participants originally assigned to PT continued PT during the extension; the remainder served as controls. Primary outcome measurements were the parent-rated Swanson, Nolan and Pelham ADHD scale and the Home Situations Questionnaire. Sixty percent (26 of 43) of treatment responders in the acute trial, including 68% of responders originally assigned to ATX, still met the response criteria at the end of the extension. The response rate of placebo nonresponders treated with 10-week open-label ATX was 37% (15 of 41), similar to the acute trial. Children receiving open-label ATX + PT were significantly more likely to be ADHD responders (53% versus 23%) and noncompliance responders (58% versus 14%) than those receiving open-label ATX alone. Most ATX responders maintained their responses during the extension. PT combined with ATX in the open-label trial appeared to improve ADHD and noncompliance outcomes more than ATX alone.

Effects of labeling and interpersonal contact upon attitudes towards schizophrenia: implications for reducing mental illness stigma in urban China

Lo, Graciete; WonPat-Borja, Ahtoy J.; Singla, Daisy R.; Link, Bruce G.; Phillips, Michael R.

2013-01-01

Purpose As mental illness stigma contributes to poor outcomes for schizophrenia in China, locating strategies to reduce public stigma is imperative. It is currently unknown whether diagnostic labeling and contact with different help-seeking sources increase or decrease public stigma in China. Further, it remains unresolved whether prior personal contact acts to reduce stigma in this context. Advancing understanding of these processes may facilitate stigma-reduction strategies. Methods We administered an experimental vignette randomly assigning one of four labeling conditions to respondents to assess social distance towards a psychotic vignette individual in a sample of 160 Northern, urban Chinese community respondents. Results As expected, respondents given a “non-psychiatric, indigenous label” + “lay help-seeking” condition endorsed the least social distance. Unexpectedly, the labeling condition with a “psychiatric diagnostic label” + “lay help-seeking” condition elicited the greatest social distance. Unlike Western studies, personal contact did not independently decrease community stigma. However, prior contact reduced social distance to a greater extent in the labeling condition with a “non-psychiatric, indigenous label” + “lay help-seeking” condition when compared with all other labeling conditions. Conclusion The results indicate that cultural idioms do provide some protection from stigma, but only among respondents who are already familiar with what mental illness is. Our finding that the condition that depicted untreated psychosis elicited the greatest amount of stigma, while the “treated psychosis” condition was viewed relatively benignly in China, suggests that improved access to mental health services in urban China has the potential to decrease public stigma via labeling mechanisms.

Therefore the question arose, "Could the implementation of parallel processing speed up the calculations required?" To answer this question two modifications of the HZETRN computer code were created. The first modification selected the shield material of Al(2219) , then polyethylene and then Al(2219). The modified Fortran code was labeled 1SSTRN.F. The second modification considered the shield material of CO2 and Martian regolith. This modified Fortran code was labeled MARSTRN.F.

Veldhuis, Jolanda; Konijn, Elly A; Seidell, Jacob C

2012-06-01

To examine how weight information labels on variously sized media models affect (pre)adolescent girls' body perceptions and how they compare themselves with media models. We used a three (body shape: extremely thin vs. thin vs. normal weight) × three (information label: 6-kg underweight vs. 3-kg underweight vs. normal weight) experimental design in three age-groups (9-10 years, 12-13 years, and 15-16 years; n = 184). The girls completed questionnaires after exposure to media models. Weight information labels affected girls' body dissatisfaction, social comparison with media figures, and objectified body consciousness. Respondents exposed to an extremely thin body shape labeled to be of "normal weight" were most dissatisfied with their own bodies and showed highest levels of objectified body consciousness and comparison with media figures. An extremely thin body shape combined with a corresponding label (i.e., 6-kg underweight), however, induced less body dissatisfaction and less comparison with the media model. Age differences were also found to affect body perceptions: adolescent girls showed more negative body perceptions than preadolescents. Weight information labels may counteract the generally media-induced thin-body ideal. That is, when the weight labels appropriately informed the respondents about the actual thinness of the media model's body shape, girls were less affected. Weight information labels also instigated a normalization effect when a "normal-weight" label was attached to underweight-sized media models. Presenting underweight as a normal body shape, clearly increased body dissatisfaction in girls. Results also suggest age between preadolescence and adolescence as a critical criterion in responding to media models' body shape. Copyright © 2012 Society for Adolescent Health and Medicine.

Farm Mapping to Assist, Protect, and Prepare Emergency Responders: Farm MAPPER.

PubMed

Reyes, Iris; Rollins, Tami; Mahnke, Andrea; Kadolph, Christopher; Minor, Gerald; Keifer, Matthew

2014-01-01

Responders such as firefighters and emergency medical technicians who respond to farm emergencies often face complex and unknown environments. They may encounter hazards such as fuels, solvents, pesticides, caustics, and exploding gas storage cylinders. Responders may be unaware of dirt roads within the farm that can expedite their arrival at critical sites or snow-covered manure pits that act as hidden hazards. A response to a farm, unless guided by someone familiar with the operation, may present a risk to responders and post a challenge in locating the victim. This project explored the use of a Web-based farm-mapping application optimized for tablets and accessible via easily accessible on-site matrix barcodes, or quick response codes (QR codes), to provide emergency responders with hazard and resource information to agricultural operations. Secured portals were developed for both farmers and responders, allowing both parties to populate and customize farm maps with icons. Data were stored online and linked to QR codes attached to mailbox posts where emergency responders may read them with a mobile device. Mock responses were conducted on dairy farms to test QR code linking efficacy, Web site security, and field usability. Findings from farmer usability tests showed willingness to enter data as well as ease of Web site navigation and data entry even with farmers who had limited computer knowledge. Usability tests with emergency responders showed ease of QR code connectivity to the farm maps and ease of Web site navigation. Further research is needed to improve data security as well as assess the program's applicability to nonfarm environments and integration with existing emergency response systems. The next phases of this project will expand the program for regional and national use, develop QR code-linked, Web-based extrication guidance for farm machinery for victim entrapment rescue, and create QR code-linked online training videos and materials for limited English proficient immigrant farm workers.

Holographic Labeling And Reading Machine For Authentication And Security Appications

DOEpatents

Weber, David C.; Trolinger, James D.

1999-07-06

A holographic security label and automated reading machine for marking and subsequently authenticating any object such as an identification badge, a pass, a ticket, a manufactured part, or a package is described. The security label is extremely difficult to copy or even to read by unauthorized persons. The system comprises a holographic security label that has been created with a coded reference wave, whose specification can be kept secret. The label contains information that can be extracted only with the coded reference wave, which is derived from a holographic key, which restricts access of the information to only the possessor of the key. A reading machine accesses the information contained in the label and compares it with data stored in the machine through the application of a joint transform correlator, which is also equipped with a reference hologram that adds additional security to the procedure.

Effect of task demands on dual coding of pictorial stimuli.

PubMed

Babbitt, B C

1982-01-01

Recent studies have suggested that verbal labeling of a picture does not occur automatically. Although several experiments using paired-associate tasks produced little evidence indicating the use of a verbal code with picture stimuli, the tasks were probably not sensitive to whether the codes were activated initially. It is possible that verbal labels were activated at input, but not used later in performing the tasks. The present experiment used a color-naming interference task in order to assess, with a more sensitive measure, the amount of verbal coding occurring in response to word or picture input. Subjects named the color of ink in which words were printed following either word or picture input. If verbal labeling of the input occurs, then latency of color naming should increase when the input item and color-naming word are related. The results provided substantial evidence of such verbal activation when the input items were words. However, the presence of verbal activation with picture input was a function of task demands. Activation occurred when a recall memory test was used, but not when a recognition memory test was used. The results support the conclusion that name information (labels) need not be activated during presentation of visual stimuli.

Learning Discriminative Binary Codes for Large-scale Cross-modal Retrieval.

PubMed

Xu, Xing; Shen, Fumin; Yang, Yang; Shen, Heng Tao; Li, Xuelong

2017-05-01

Hashing based methods have attracted considerable attention for efficient cross-modal retrieval on large-scale multimedia data. The core problem of cross-modal hashing is how to learn compact binary codes that construct the underlying correlations between heterogeneous features from different modalities. A majority of recent approaches aim at learning hash functions to preserve the pairwise similarities defined by given class labels. However, these methods fail to explicitly explore the discriminative property of class labels during hash function learning. In addition, they usually discard the discrete constraints imposed on the to-be-learned binary codes, and compromise to solve a relaxed problem with quantization to obtain the approximate binary solution. Therefore, the binary codes generated by these methods are suboptimal and less discriminative to different classes. To overcome these drawbacks, we propose a novel cross-modal hashing method, termed discrete cross-modal hashing (DCH), which directly learns discriminative binary codes while retaining the discrete constraints. Specifically, DCH learns modality-specific hash functions for generating unified binary codes, and these binary codes are viewed as representative features for discriminative classification with class labels. An effective discrete optimization algorithm is developed for DCH to jointly learn the modality-specific hash function and the unified binary codes. Extensive experiments on three benchmark data sets highlight the superiority of DCH under various cross-modal scenarios and show its state-of-the-art performance.

Direct fluorescent-dye labeling of α-tubulin in mammalian cells for live cell and superresolution imaging

2017-01-01

Genetic code expansion and bioorthogonal labeling provide for the first time a way for direct, site-specific labeling of proteins with fluorescent-dyes in live cells. Although the small size and superb photophysical parameters of fluorescent-dyes offer unique advantages for high-resolution microscopy, this approach has yet to be embraced as a tool in live cell imaging. Here we evaluated the feasibility of this approach by applying it for α-tubulin labeling. After a series of calibrations, we site-specifically labeled α-tubulin with silicon rhodamine (SiR) in live mammalian cells in an efficient and robust manner. SiR-labeled tubulin successfully incorporated into endogenous microtubules at high density, enabling video recording of microtubule dynamics in interphase and mitotic cells. Applying this labeling approach to structured illumination microscopy resulted in an increase in resolution, highlighting the advantages in using a smaller, brighter tag. Therefore, using our optimized assay, genetic code expansion provides an attractive tool for labeling proteins with a minimal, bright tag in quantitative high-resolution imaging. PMID:28835375

Young children's coding and storage of visual and verbal material.

PubMed

Perlmutter, M; Myers, N A

1975-03-01

36 preschool children (mean age 4.2 years) were each tested on 3 recognition memory lists differing in test mode (visual only, verbal only, combined visual-verbal). For one-third of the children, original list presentation was visual only, for another third, presentation was verbal only, and the final third received combined visual-verbal presentation. The subjects generally performed at a high level of correct responding. Verbal-only presentation resulted in less correct recognition than did either visual-only or combined visual-verbal presentation. However, because performances under both visual-only and combined visual-verbal presentation were statistically comparable, and a high level of spontaneous labeling was observed when items were presented only visually, a dual-processing conceptualization of memory in 4-year-olds was suggested.

Identifying Objects via Encased X-Ray-Fluorescent Materials - the Bar Code Inside

NASA Technical Reports Server (NTRS)

Schramm, Harry F.; Kaiser, Bruce

2005-01-01

Systems for identifying objects by means of x-ray fluorescence (XRF) of encased labeling elements have been developed. The XRF spectra of objects so labeled would be analogous to the external bar code labels now used to track objects in everyday commerce. In conjunction with computer-based tracking systems, databases, and labeling conventions, the XRF labels could be used in essentially the same manner as that of bar codes to track inventories and to record and process commercial transactions. In addition, as summarized briefly below, embedded XRF labels could be used to verify the authenticity of products, thereby helping to deter counterfeiting and fraud. A system, as described above, is called an encased core product identification and authentication system (ECPIAS). The ECPIAS concept is a modified version of that of a related recently initiated commercial development of handheld XRF spectral scanners that would identify alloys or detect labeling elements deposited on the surfaces of objects. In contrast, an ECPIAS would utilize labeling elements encased within the objects of interest. The basic ECPIAS concept is best illustrated by means of an example of one of several potential applications: labeling of cultured pearls by labeling the seed particles implanted in oysters to grow the pearls. Each pearl farmer would be assigned a unique mixture of labeling elements that could be distinguished from the corresponding mixtures of other farmers. The mixture would be either incorporated into or applied to the surfaces of the seed prior to implantation in the oyster. If necessary, the labeled seed would be further coated to make it nontoxic to the oyster. After implantation, the growth of layers of mother of pearl on the seed would encase the XRF labels, making these labels integral, permanent parts of the pearls that could not be removed without destroying the pearls themselves. The XRF labels would be read by use of XRF scanners, the spectral data outputs of which would be converted to alphanumeric data in a digital equivalent data system (DEDS), which is the subject of the previous article. These alphanumeric data would be used to track the pearls through all stages of commerce, from the farmer to the retail customer.

The purpose of the present study was to examine the effects of food label nutrition colouring schemes in interaction with food category healthiness on consumers' perceptions of food healthiness. Three streams of colour theory (colour attention, colour association and colour approach-avoidance) in interaction with heuristic processing theory provide consonant predictions and explanations for the underlying psychological processes. A 2 (food category healthiness: healthy v. unhealthy)×3 (food label nutrient colouring schemes: healthy=green, unhealthy=red (HGUR) v. healthy=red, unhealthy=green (HRUG) v. no colour (control)) between-subjects design was used. The research setting was a randomised-controlled experiment using varying formats of food packages and nutritional information colouring. Respondents (n 196) sourced from a national consumer panel, USA. The findings suggest that, for healthy foods, the nutritional colouring schemes reduced perceived healthiness, irrespective of which nutrients were coloured red or green (healthinesscontrol=4·86; healthinessHGUR=4·10; healthinessHRUG=3·70). In contrast, for unhealthy foods, there was no significant difference in perceptions of food healthiness when comparing different colouring schemes against the control. The results make an important qualification to the common belief that colour coding can enhance the correct interpretation of nutrition information and suggest that this incentive may not necessarily support healthier food choices in all situations.

Cigarette pack warning labels in Russia: how graphic should they be?

2011-06-01

Tobacco warning labels on cigarette packs have been shown to reduce cigarette consumption. The current study measures the Russian population's acceptance and preference of graphic (picture + text) tobacco warning labels. Nationally representative data were collected from 1778 participants in the Russian Federation in October 2009. A cross-sectional survey was conducted through person-to-person household interviews with respondents aged ≥ 14 years. Survey questions included standard demographic queries and three study-specific questions. Participants rated the strength of 13 cigarette warning labels according to their effectiveness to deter from smoking. Smoking status and the population's acceptance of similar warning labels was also measured. A dose-response pattern is apparent between the degree of graphic content of cigarette warning labels and the public's perception regarding the warning label's ability to discourage smoking. Approximately 87% of all respondents thought Russian authorities should require tobacco manufacturers to place graphic warning labels on cigarette packs, while 80% of current smokers wanted their government to enact such enforcement. The Russian population would strongly support government policy that would require graphic warning labels to be placed on cigarette packs in their country. In order to best deter from smoking, future cigarette warning labels in Russia should be as graphic as possible.

Visualization and Analysis of Microtubule Dynamics Using Dual Color-Coded Display of Plus-End Labels

PubMed Central

Garrison, Amy K.; Xia, Caihong; Wang, Zheng; Ma, Le

2012-01-01

Investigating spatial and temporal control of microtubule dynamics in live cells is critical to understanding cell morphogenesis in development and disease. Tracking fluorescently labeled plus-end-tracking proteins over time has become a widely used method to study microtubule assembly. Here, we report a complementary approach that uses only two images of these labels to visualize and analyze microtubule dynamics at any given time. Using a simple color-coding scheme, labeled plus-ends from two sequential images are pseudocolored with different colors and then merged to display color-coded ends. Based on object recognition algorithms, these colored ends can be identified and segregated into dynamic groups corresponding to four events, including growth, rescue, catastrophe, and pause. Further analysis yields not only their spatial distribution throughout the cell but also provides measurements such as growth rate and direction for each labeled end. We have validated the method by comparing our results with ground-truth data derived from manual analysis as well as with data obtained using the tracking method. In addition, we have confirmed color-coded representation of different dynamic events by analyzing their history and fate. Finally, we have demonstrated the use of the method to investigate microtubule assembly in cells and provided guidance in selecting optimal image acquisition conditions. Thus, this simple computer vision method offers a unique and quantitative approach to study spatial regulation of microtubule dynamics in cells. PMID:23226282

In photonic label routers, various optical signal processing functions are required; these include optical label extraction, recognition of the label, optical switching and buffering controlled by signals based on the label information and network routing tables, and label rewriting. Among these functions, we focus on photonic label recognition. We have proposed two kinds of optical waveguide circuits to recognize 16 quadrature amplitude modulation codes, i.e., recognition from the minimum output port and from the maximum output port. The recognition function was theoretically analyzed and numerically simulated by finite-difference beam-propagation method. We discuss noise tolerance in the circuit and show numerically simulated results to evaluate bit-error-rate (BER) characteristics against optical signal-to-noise ratio (OSNR). The OSNR required to obtain a BER less than 1.0×10-3 for the symbol rate of 2.5 GBaud was 14.5 and 27.0 dB for recognition from the minimum and maximum output, respectively.

2015-01-01

Numeric calorie content labels show limited efficacy in reducing the number of calories ordered from fast food meals. Physical activity calorie equivalent (PACE) labels are an alternative that may reduce the number of calories ordered in fast food meals while encouraging patrons to exercise. A total of 1000 adults from 47 US states were randomly assigned via internet survey to one of four generic fast food menus: no label, calories only, calories + minutes, or calories + miles necessary to walk to burn off the calories. After completing hypothetical orders participants were asked to rate the likelihood of calorie-only and PACE labels to influence (1) food choice and (2) physical activity. Respondents (n = 823) ordered a median of 1580 calories from the no-label menu, 1200 from the calories-only menu, 1140 from the calories + minutes menu, and 1210 from the calories + miles menu (p = 0.0001). 40% of respondents reported that PACE labels were "very likely" to influence food item choice vs. 28% for calorie-only labels (p<0.0001). 64% of participants reported that PACE labels were "somewhat likely" or "very likely" to influence their level of physical activity vs. 49% for calorie-only labels (p<0.0001). PACE labels may be helpful in reducing the number of calories ordered in fast food meals and may have the added benefit of encouraging exercise.

We evaluated the direct and generalized effects of cues-pause-point language training procedures on immediate echolalia and correct responding in two severely retarded females. Two experiments were conducted with each subject in which the overall goal was to encourage them to remain quiet before, during, and briefly after the presentation of questions and then to verbalize on the basis of environmental cues whose labels represented the correct responses. Multiple baseline designs across question/response pairs (Experiment I) or question/response pairs and settings (Experiment II) demonstrated that echolalia was rapidly replaced by correct responding on the trained stimuli. More importantly, there were clear improvements in subjects' responding to untrained stimuli. Results demonstrated that the cues-pause-point procedures can be effective in teaching severely retarded or echolalic individuals functional use of their verbal labeling repertoires. PMID:3583962

Synthetic DNA has been used as an authentication code for a diverse number of applications. However, existing decoding approaches are based on either DNA sequencing or the determination of DNA length variations. Here, we present a simple alternative protocol for labeling different objects using a small number of short DNA sequences that differ in their melting points. Code amplification and decoding can be done in two steps using quantitative PCR (qPCR). To obtain a DNA barcode with high complexity, we defined 8 template groups, each having 4 different DNA templates, yielding 158 (>2.5 billion) combinations of different individual melting temperature (Tm) values and corresponding ID codes. The reproducibility and specificity of the decoding was confirmed by using the most complex template mixture, which had 32 different products in 8 groups with different Tm values. The industrial applicability of our protocol was also demonstrated by labeling a drone with an oil-based paint containing a predefined DNA code, which was then successfully decoded. The method presented here consists of a simple code system based on a small number of synthetic DNA sequences and a cost-effective, rapid decoding protocol using a few qPCR reactions, enabling a wide range of authentication applications.

Salt reduction is one of the most important lifestyle modifications for the prevention of hypertension. The health promotion law regulates the labeling of the nutrient content of food in Japan and, the level of sodium, not salt (sodium chloride), has to be printed on the labels of manufactured foods. In order to control their salt intake, consumers need to apply a conversion factor to the sodium levels listed on the labels to obtain the salt equivalent. However, it is not known whether people have the knowledge appropriate for making the conversion. We carried out a questionnaire survey at the 7th National Shokuiku (food education) Conference in 2012, asking subjects to determine the salt equivalent of 1000 mg of sodium on food labels. We also asked about the target values of salt reduction in grams in the Dietary Reference Intakes for Japanese 2010 (DRI2010) and the Guidelines for Management of Hypertension 2009 by the Japanese Society of Hypertension (JSH2009). We analyzed the data from 683 respondents (169 men and 514 women); only 13.3% of respondents gave a correct answer for the salt equivalent of 1000 mg of sodium (2.50-2.60 g), whereas 61.8 and 40.4% of respondents chose the correct target values for salt reduction according to DRI2010 and JSH2009, respectively. In conclusion, few people could convert sodium content to salt, which suggested difficulty in using food labels to control their salt intake. Salt content in grams, not sodium content, should be labeled on food packages for effective salt reduction and prevention of hypertension.

The purpose of this study is to assess medical ethics knowledge among trainees and practicing radiologists through an online survey that included questions about the American College of Radiology Code of Ethics and the American Medical Association Code of Medical Ethics. Most survey respondents reported that they had never read the American Medical Association Code of Medical Ethics or the American College of Radiology Code of Ethics (77.2% and 67.4% of respondents, respectively). With regard to ethics education during medical school and residency, 57.3% and 70.0% of respondents, respectively, found such education to be insufficient. Medical ethics training should be highlighted during residency, at specialty society meetings, and in journals and online resources for radiologists.

An empirical evaluation of supervised learning approaches in assigning diagnosis codes to electronic medical records

2015-01-01

Background Diagnosis codes are assigned to medical records in healthcare facilities by trained coders by reviewing all physician authored documents associated with a patient's visit. This is a necessary and complex task involving coders adhering to coding guidelines and coding all assignable codes. With the popularity of electronic medical records (EMRs), computational approaches to code assignment have been proposed in the recent years. However, most efforts have focused on single and often short clinical narratives, while realistic scenarios warrant full EMR level analysis for code assignment. Objective We evaluate supervised learning approaches to automatically assign international classification of diseases (ninth revision) - clinical modification (ICD-9-CM) codes to EMRs by experimenting with a large realistic EMR dataset. The overall goal is to identify methods that offer superior performance in this task when considering such datasets. Methods We use a dataset of 71,463 EMRs corresponding to in-patient visits with discharge date falling in a two year period (2011–2012) from the University of Kentucky (UKY) Medical Center. We curate a smaller subset of this dataset and also use a third gold standard dataset of radiology reports. We conduct experiments using different problem transformation approaches with feature and data selection components and employing suitable label calibration and ranking methods with novel features involving code co-occurrence frequencies and latent code associations. Results Over all codes with at least 50 training examples we obtain a micro F-score of 0.48. On the set of codes that occur at least in 1% of the two year dataset, we achieve a micro F-score of 0.54. For the smaller radiology report dataset, the classifier chaining approach yields best results. For the smaller subset of the UKY dataset, feature selection, data selection, and label calibration offer best performance. Conclusions We show that datasets at different scale (size of the EMRs, number of distinct codes) and with different characteristics warrant different learning approaches. For shorter narratives pertaining to a particular medical subdomain (e.g., radiology, pathology), classifier chaining is ideal given the codes are highly related with each other. For realistic in-patient full EMRs, feature and data selection methods offer high performance for smaller datasets. However, for large EMR datasets, we observe that the binary relevance approach with learning-to-rank based code reranking offers the best performance. Regardless of the training dataset size, for general EMRs, label calibration to select the optimal number of labels is an indispensable final step. PMID:26054428

We taught three mentally handicapped students to answer questions with verbal labels and evaluated the generalized effects of this training on their maladaptive speech (e.g., echolalia) and correct responding to untrained questions. The students received cues-pause-point training on an initial question set followed by generalization assessments on a different set in another setting. Probes were conducted on novel questions in three other settings to determine the strength and spread of the generalization effect. A multiple baseline across subjects design revealed that maladaptive speech was replaced with correct labels (answers) to questions in the training and all generalization settings. These results replicate and extend previous research that suggested that cues-pause-point procedures may be useful in replacing maladaptive speech patterns by teaching students to use their verbal labeling repertoires.

Digital Equivalent Data System for XRF Labeling of Objects

NASA Technical Reports Server (NTRS)

Schramm, Harry F.; Kaiser, Bruce

2005-01-01

A digital equivalent data system (DEDS) is a system for identifying objects by means of the x-ray fluorescence (XRF) spectra of labeling elements that are encased in or deposited on the objects. As such, a DEDS is a revolutionary new major subsystem of an XRF system. A DEDS embodies the means for converting the spectral data output of an XRF scanner to an ASCII alphanumeric or barcode label that can be used to identify (or verify the assumed or apparent identity of) an XRF-scanned object. A typical XRF spectrum of interest contains peaks at photon energies associated with specific elements on the Periodic Table (see figure). The height of each spectral peak above the local background spectral intensity is proportional to the relative abundance of the corresponding element. Alphanumeric values are assigned to the relative abundances of the elements. Hence, if an object contained labeling elements in suitably chosen proportions, an alphanumeric representation of the object could be extracted from its XRF spectrum. The mixture of labeling elements and for reading the XRF spectrum would be compatible with one of the labeling conventions now used for bar codes and binary matrix patterns (essentially, two-dimensional bar codes that resemble checkerboards). A further benefit of such compatibility is that it would enable the conversion of the XRF spectral output to a bar or matrix-coded label, if needed. In short, a process previously used only for material composition analysis has been reapplied to the world of identification. This new level of verification is now being used for "authentication."

2013-01-01

Background In 2010, the US Food and Drug Administration (FDA) proposed a series of 36 graphic warning labels for cigarette packages. We sought to evaluate the effects of the labels on fear-related emotions about health consequences of smoking and smoking motivations of young adults. Methods We conducted an experimental study in 2010–2011 with 325 smokers and non-smokers ages 18–30 years whom we recruited through community distribution lists in North Carolina and through a national survey company. Each participant viewed 27 labels (18 of the proposed labels with graphic images and text warnings and 9 with text-only warnings) in a random order, evaluating each label on understandability and its effects on fear-related reactions and discouragement from wanting to smoke. Results Respondents found most of the proposed labels easy to understand. Of the 36 labels, 64% induced greater fear-related reactions and 58% discouraged respondents from wanting to smoke more than the corresponding text-only labels did. Labels with the greatest effects had photographs (as compared with drawings or other art graphics) or depicted diseased body parts or suffering or dead people. In almost every comparison, smokers reported lower fear-related reactions and feeling less discouraged from wanting to smoke relative to non-smokers. Conclusions Most of the proposed labels enhanced fear-related reactions about health consequences of smoking and reduced motivations to smoke relative to text-only labels, although some had larger effects than others. All but one of the nine warning labels recently adopted by the FDA enhanced fear-related reactions and reduced smoking motivations. PMID:23624558

Potential Effect of Physical Activity Calorie Equivalent (PACE) Labeling on Adult Fast Food Ordering and Exercise

Antonelli, Ray; Viera, Anthony J.

2015-01-01

Introduction Numeric calorie content labels show limited efficacy in reducing the number of calories ordered from fast food meals. Physical activity calorie equivalent (PACE) labels are an alternative that may reduce the number of calories ordered in fast food meals while encouraging patrons to exercise. Methods A total of 1000 adults from 47 US states were randomly assigned via internet survey to one of four generic fast food menus: no label, calories only, calories + minutes, or calories + miles necessary to walk to burn off the calories. After completing hypothetical orders participants were asked to rate the likelihood of calorie-only and PACE labels to influence (1) food choice and (2) physical activity. Results Respondents (n = 823) ordered a median of 1580 calories from the no-label menu, 1200 from the calories-only menu, 1140 from the calories + minutes menu, and 1210 from the calories + miles menu (p = 0.0001). 40% of respondents reported that PACE labels were “very likely” to influence food item choice vs. 28% for calorie-only labels (p<0.0001). 64% of participants reported that PACE labels were “somewhat likely” or “very likely” to influence their level of physical activity vs. 49% for calorie-only labels (p<0.0001). Conclusions PACE labels may be helpful in reducing the number of calories ordered in fast food meals and may have the added benefit of encouraging exercise. PMID:26222056

Smoking tobacco is considered as a leading cause of preventable death, mostly in developing countries like India. One of the primary goals of international tobacco control is to educate smokers about the risks associated with tobacco consumption. Tobacco warning labels (TWLs) on cigarette packages are one of the most common statutory means to communicate health risks of smoking to smokers, with the hope that once educated, they will be more likely to quit the habit. The present survey was conducted to assess the effectiveness of TWLs in communicating health risks of tobacco usage among 263 adult smokers working as bus drivers in Karnataka State Road Transport Corporation (KSRTC), Mangalore, India. Information was collected on demographic details, exposure and response to health warnings on tobacco products, intention to quit and nicotine dependency. The majority (79.5%) of the respondents revealed negative intentions towards quitting smoking. Nearly half of the participants had a 'low' nicotine dependency (47.5%) and 98.1% of the respondents had often noticed warning labels on tobacco packages. These health warnings made 71.5% of the respondents think about quitting smoking. Respondents who noticed advertisement or pictures about dangers of smoking had better knowledge, with respect to lung cancer and impotence as a consequence of tobacco. A higher exposure to warning labels was significantly associated with lower nicotine dependency levels of smokers among the present study population. A significantly higher number of respondents who noticed advertisement or pictures about the dangers of smoking thought about the risks of smoking and were more inclined to think about quitting smoking. As exposure increased, an increase in the knowledge and response of participants was also observed. Exposure to tobacco warning labels helps to educate smokers about health risks of tobacco smoking. It may be possible to promote oral health among bus drivers by developing strategies to educate them about these risk factors.

1991-01-01

"Investigation of Professionalism in Nursing Behaviors" was funded by the Beta Upsilon Chapter of Sigma Theta Tau International and the College of Nursing, Arizona State University. Researchers asked 514 nurses in eight western states if they had a copy of the Code For Nurses. Most respondents did not have a copy of the Code; however, they indicated that adherence to the Code was essential to the professional nurse. Years of practice, educational background, participation in autonomous activities, and present position were variables used to determine those respondents most likely to possess a copy of the Code. Implications for continuing educators are discussed.

PCR-free quantitative detection of genetically modified organism from raw materials. An electrochemiluminescence-based bio bar code method.

2008-05-15

A bio bar code assay based on oligonucleotide-modified gold nanoparticles (Au-NPs) provides a PCR-free method for quantitative detection of nucleic acid targets. However, the current bio bar code assay requires lengthy experimental procedures including the preparation and release of bar code DNA probes from the target-nanoparticle complex and immobilization and hybridization of the probes for quantification. Herein, we report a novel PCR-free electrochemiluminescence (ECL)-based bio bar code assay for the quantitative detection of genetically modified organism (GMO) from raw materials. It consists of tris-(2,2'-bipyridyl) ruthenium (TBR)-labeled bar code DNA, nucleic acid hybridization using Au-NPs and biotin-labeled probes, and selective capture of the hybridization complex by streptavidin-coated paramagnetic beads. The detection of target DNA is realized by direct measurement of ECL emission of TBR. It can quantitatively detect target nucleic acids with high speed and sensitivity. This method can be used to quantitatively detect GMO fragments from real GMO products.

The Guidelines for the implementation of Article 11 of the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) require that cigarette health warning labels should include pictures and take up 50% or more of the principal display area. This study examined how the association between large pictorial warnings, those covering ≥50% of the front and back of the package, and the prevalence of cigarette smoking varies by educational attainment. We pooled individual-level tobacco use data from the Global Adult Tobacco Survey (GATS) in 18 countries between 2008 and 2013 and linked them with warning label requirements during the same period from the MPOWER database and reports regarding warnings. The respondents' self-reported exposure to warnings was examined according to education. Logistic regressions were further employed to analyze education-specific associations between large pictorial warnings and smoking prevalence, and whether such association differed by education was examined using an interaction test. At the time of the survey, eight out of 18 countries had imposed graphic warning labels that covered ≥50% of the package. These warnings were associated with a 10.0% (OR = 0.89; 95% CI: 0.81, 0.97; p ≤ 0.01) lower cigarette smoking prevalence among adults with less than a secondary education or no formal education, but not among respondents with at least a secondary education. Less educated respondents were also less likely to be exposed to warnings in all 18 countries. The association between strong warnings and lower smoking prevalence among less educated respondents could be greater if their exposure to warnings increases. Prominent pictorial warning labels can potentially reduce health disparities resulting from smoking across different education levels.

Mandatory labeling of products with top allergens has improved food safety for consumers. Precautionary allergen labeling (PAL), such as "may contain" or "manufactured on shared equipment," are voluntarily placed by the food industry. To establish knowledge of PAL and its impact on purchasing habits by food-allergic consumers in North America. Food Allergy Research & Education and Food Allergy Canada surveyed consumers in the United States and Canada on purchasing habits of food products featuring different types of PAL. Associations between respondents' purchasing behaviors and individual characteristics were estimated using multiple logistic regression. Of 6684 participants, 84.3% (n = 5634) were caregivers of a food-allergic child and 22.4% had food allergy themselves. Seventy-one percent reported a history of experiencing a severe allergic reaction. Buying practices varied on the basis of PAL wording; 11% of respondents purchased food with "may contain" labeling, whereas 40% purchased food that used "manufactured in a facility that also processes." Twenty-nine percent of respondents were unaware that the law requires labeling of priority food allergens. Forty-six percent were either unsure or incorrectly believed that PAL is required by law. Thirty-seven percent of respondents thought PAL was based on the amount of allergen present. History of a severe allergic reaction decreased the odds of purchasing foods with PAL. Almost half of consumers falsely believed that PAL was required by law. Up to 40% surveyed consumers purchased products with PAL. Understanding of PAL is poor, and improved awareness and guidelines are needed to help food-allergic consumers purchase food safely. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

2017-08-01

Many older adult immigrants in the US, including Hmong older adults, have limited English proficiency (LEP), and cannot read or have difficulty reading even in their first language (non-literate [NL]). Little has been done to identify feasible data collection approaches to enable inclusion of LEP or NL populations in research, limiting knowledge about their health. This study's purpose was to test the feasibility of culturally and linguistically adapted audio computer-assisted self-interviewing (ACASI) with color-labeled response categories and helper assistance (ACASI-H) for collection of health data with Hmong older adults. Thirty dyads (older adult and a helper) completed an ACASI-H survey with 13 health questions and a face-to-face debriefing interview. ACASI-H survey completion was video-recorded and reviewed with participants. Video review and debriefing interviews were audio-recorded and transcribed. Directed and conventional content analyses were used to analyze the interviews. All respondents reported that ACASI-H survey questions were consistent with their health experience. They lacked computer experience and found ACASI-H's interface user-friendly. All used the pre-recorded Hmong oral translation except for one, whose helper provided translation. Some Hmong older adults struggled with the color labeling at first, but helpers guided them to use the colors correctly. All dyads liked the color-labeled response categories and confirmed that a helper was necessary during the survey process. Findings support use of oral survey question administration with a technologically competent helper and color-labeled response categories when engaging LEP older adults in health-related data collection. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

The Efficacy of Cigarette Warning Labels on Health Beliefs in the United States and Mexico

2013-01-01

Concern over health risks is the most common motivation for quitting smoking. Health warnings on tobacco packages are among the most prominent interventions to convey the health risks of smoking. Face-to-face surveys were conducted in Mexico (n=1,072), and a web-based survey was conducted in the US (n=1,449) to examine the efficacy of health warning labels on health beliefs. Respondents were randomly assigned to view two sets of health warnings (each with one text-only warning and 5–6 pictorial warnings) for two different health effects. Respondents were asked whether they believed smoking caused 12 different health effects. Overall, the findings indicate high levels of health knowledge in both countries for some health effects, although significant knowledge gaps remained; for example: less than half of respondents agreed that smoking causes impotence and less than one third agreed that smoking causes gangrene. Mexican respondents endorsed a greater number of correct beliefs about the health impact of smoking than the US sample. In both countries, viewing related health warning labels increased beliefs about the health risks of smoking, particularly for less well-known health effects, such as gangrene, impotence, and stroke.

Previous studies focused on a limited number of determinants of food label use. We therefore tested a comprehensive model of food label use consisting of sociodemographic, health-related and motivating variables. These three predictor groups were chosen based on the previous literature and completed with new predictors not yet examined in a comprehensive study of frequency of label use. We sent questionnaires to a random sample of households in the German-speaking part of Switzerland. The respondents filled in the questionnaire at home and returned it by mail. We analysed the data of 1162 filled-in questionnaires (response rate = 38 %). Of the respondents, 637 were women (55 %), and their mean age was 53·54 (sd 15·68) years. Health-related variables were the most important group of predictors of label use, followed by motivating factors and sociodemographic variables. Placing importance on health, healthy eating and nutritional value of food, perceived vulnerability for diet-related diseases, nutrition knowledge, numeracy and gender were positively associated with frequency of food label use whereas shopping habits and seeing eating as something positive were negative predictors of frequency of label use. People's health consciousness should be raised in order to increase the frequency of food label use. Furthermore, it should be stressed that reading labels and keeping a healthy diet do not contradict 'good eating', and that both of these aspects can be combined with the help of food labels.

Facile and High-Throughput Synthesis of Functional Microparticles with Quick Response Codes.

PubMed

Ramirez, Lisa Marie S; He, Muhan; Mailloux, Shay; George, Justin; Wang, Jun

2016-06-01

Encoded microparticles are high demand in multiplexed assays and labeling. However, the current methods for the synthesis and coding of microparticles either lack robustness and reliability, or possess limited coding capacity. Here, a massive coding of dissociated elements (MiCODE) technology based on innovation of a chemically reactive off-stoichimetry thiol-allyl photocurable polymer and standard lithography to produce a large number of quick response (QR) code microparticles is introduced. The coding process is performed by photobleaching the QR code patterns on microparticles when fluorophores are incorporated into the prepolymer formulation. The fabricated encoded microparticles can be released from a substrate without changing their features. Excess thiol functionality on the microparticle surface allows for grafting of amine groups and further DNA probes. A multiplexed assay is demonstrated using the DNA-grafted QR code microparticles. The MiCODE technology is further characterized by showing the incorporation of BODIPY-maleimide (BDP-M) and Nile Red fluorophores for coding and the use of microcontact printing for immobilizing DNA probes on microparticle surfaces. This versatile technology leverages mature lithography facilities for fabrication and thus is amenable to scale-up in the future, with potential applications in bioassays and in labeling consumer products. © 2016 WILEY-VCH Verlag GmbH & Co.

2013-01-01

This study examined Japanese consumers' valuation of a good agricultural practice (GAP) label on packaged milk and investigated the effect of detailed GAP information on valuation. A total of 624 Japanese consumers were asked to select their most preferred milk through an online survey. The milk was assumed to have three attributes: the GAP label, Hazard Analysis and Critical Control Points certification, and price. The results showed that consumers' valuation of GAP was significantly positive. Although providing additional GAP information to a respondent who was aware of GAP and what it means had a positive effect on the consumers' valuation of GAP, provision of this information had no effect if the respondent knew about GAP either moderately or slightly, and had a negative effect if the respondent did not know about GAP at all. To increase broad consumer awareness and valuation of GAP, it is important to provide GAP information according to the requirements of consumers. © 2012 The Authors.

The problem of describing the distribution of labels over a set of objects is relevant to many domains. For example: cyber security, social media, and protein interactions all care about the manner in which labels are distributed among different objects. In this paper we present three interacting statistical measures on label distributions, inspired by entropy and information theory. Labeled graphs are discussed as a specific case of labels distributed over a set of edges. We describe a use case in cyber security using a labeled directed multi-graph of IPFLOW. Finally we show how these measures respond when labels are updatedmore » in certain ways.« less

When Terminal Illness Is Worse Than Death: A Multicenter Study of Health-Care Providers' Resuscitation Desires.

PubMed

Chavez, Luis O; Einav, Sharon; Varon, Joseph

2017-11-01

To investigate how a terminal illness may affect the health-care providers' resuscitation preferences. We conducted a cross-sectional survey in 9 health-care institutions located in 4 geographical regions in North and Central America, investigating attitudes toward end-of-life practices in health-care providers. Statistical analysis included descriptive statistics and χ 2 test for the presence of associations ( P < 0.05 being significant) and Cramer V for the strength of the association. The main outcome measured the correlation between the respondents' present code status and their preference for cardiopulmonary resuscitation (CPR) in case of terminal illness. A total of 852 surveys were completed. Among the respondents, 21% (n = 180) were physicians, 36.9% (n = 317) were nurses, 10.5% (n = 90) were medical students, and 265 participants were other staff members of the institutions. Most respondents (58.3%; n = 500) desired "definitely full code" (physicians 73.2%; n = 131), only 13.8% of the respondents (physicians 8.33%; n = 15) desired "definitely no code" or "partial support," and 20.9% of the respondents (n = 179; among physicians 18.4%; n = 33) had never considered their code status. There was an association between current code status and resuscitation preference in case of terminal illness ( P < .001), but this association was overall quite weak (Cramer V = 0.180). Subgroup analysis revealed no association between current code status and terminal illness code preference among physicians ( P = .290) and nurses ( P = .316), whereupon other hospital workers were more consistent ( P < .01, Cramer V = .291). Doctors and nurses have different end-of-life preferences than other hospital workers. Their desire to undergo CPR may change when facing a terminal illness.

Ensuring accurate patient identification is central to preventing medical errors, but it can be challenging. We implemented a bar code-based positive patient identification system for use in inpatient phlebotomy. A before-after design was used to evaluate the impact of the identification system on the frequency of mislabeled and unlabeled samples reported in our laboratory. Labeling errors fell from 5.45 in 10,000 before implementation to 3.2 in 10,000 afterward (P = .0013). An estimated 108 mislabeling events were prevented by the identification system in 1 year. Furthermore, a workflow step requiring manual preprinting of labels, which was accompanied by potential labeling errors in about one quarter of blood "draws," was removed as a result of the new system. After implementation, a higher percentage of patients reported having their wristband checked before phlebotomy. Bar code technology significantly reduced the rate of specimen identification errors.

Semantic and visual memory codes in learning disabled readers.

PubMed

Swanson, H L

1984-02-01

Two experiments investigated whether learning disabled readers' impaired recall is due to multiple coding deficiencies. In Experiment 1, learning disabled and skilled readers viewed nonsense pictures without names or with either relevant or irrelevant names with respect to the distinctive characteristics of the picture. Both types of names improved recall of nondisabled readers, while learning disabled readers exhibited better recall for unnamed pictures. No significant difference in recall was found between name training (relevant, irrelevant) conditions within reading groups. In Experiment 2, both reading groups participated in recall training for complex visual forms labeled with unrelated words, hierarchically related words, or without labels. A subsequent reproduction transfer task showed a facilitation in performance in skilled readers due to labeling, with learning disabled readers exhibiting better reproduction for unnamed pictures. Measures of output organization (clustering) indicated that recall is related to the development of superordinate categories. The results suggest that learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes.

Israeli Arab and Jewish youth knowledge and opinion about alcohol warning labels: pre-intervention data.

PubMed

Weiss, S

1997-01-01

This article presents baseline data on the opinion toward alcohol beverage warning labels and on levels of knowledge of the risks discussed in the contents of the labels prior to the labels' introduction, and on levels of knowledge of additional alcohol-related hazards not included in the proposed warning labels, among a sample of 3065 adolescents of four religions living in the northern region of Israel. About 2220 Arab participants (Moslems, Christians and Druze) and 845 Jewish respondents answered in the winter of 1996 a Hebrew version of an American questionnaire, which had been used to measure levels of knowledge of the label in the United States. More respondents were in favour of warning labels on alcohol containers than on advertisements. Arabs as a group were more in favour of warning labels on alcohol containers than Jews. The initial knowledge levels among the participants were not very high, especially concerning the item 'Drinking impairs the ability to operate machinery' (74.4%) which is included on the proposed warning label, and concerning two hazards which are not included: 'Drinking increases risk of cancer' (54.6%) and 'Drinking increases risk of high blood pressure' (60.4%). Abstainers knew more than drinkers that 'Pregnant women should not drink', 'Drinking increases risk of cancer' and 'Alcohol in combination with other drugs is hazardous'. Implications for public health are discussed and alternative warning messages that might be used to inform the Israeli public of several less well-known hazards are suggested.

A DNA sequencing method described which uses single lane or channel electrophoresis. Sequencing fragments are separated in said lane and detected using a laser-excited, confocal fluorescence scanner. Each set of DNA sequencing fragments is separated in the same lane and then distinguished using a binary coding scheme employing only two different fluorescent labels. Also described is a method of using radio-isotope labels.

Genetic code expansion and bioorthogonal labeling provide for the first time a way for direct, site-specific labeling of proteins with fluorescent-dyes in live cells. Although the small size and superb photophysical parameters of fluorescent-dyes offer unique advantages for high-resolution microscopy, this approach has yet to be embraced as a tool in live cell imaging. Here we evaluated the feasibility of this approach by applying it for α-tubulin labeling. After a series of calibrations, we site-specifically labeled α-tubulin with silicon rhodamine (SiR) in live mammalian cells in an efficient and robust manner. SiR-labeled tubulin successfully incorporated into endogenous microtubules at high density, enabling video recording of microtubule dynamics in interphase and mitotic cells. Applying this labeling approach to structured illumination microscopy resulted in an increase in resolution, highlighting the advantages in using a smaller, brighter tag. Therefore, using our optimized assay, genetic code expansion provides an attractive tool for labeling proteins with a minimal, bright tag in quantitative high-resolution imaging. © 2017 Schvartz et al.

Primary afferents transduce environmental stimuli into electrical activity that is transmitted centrally to be decoded into corresponding sensations. However, it remains unknown how afferent populations encode different somatosensory inputs. To address this, we performed two-photon Ca 2+ imaging from thousands of dorsal root ganglion (DRG) neurons in anesthetized mice while applying mechanical and thermal stimuli to hind paws. We found that approximately half of all neurons are polymodal and that heat and cold are encoded very differently. As temperature increases, more heating-sensitive neurons are activated, and most individual neurons respond more strongly, consistent with graded coding at population and single-neuron levels, respectively. In contrast, most cooling-sensitive neurons respond in an ungraded fashion, inconsistent with graded coding and suggesting combinatorial coding, based on which neurons are co-activated. Although individual neurons may respond to multiple stimuli, our results show that different stimuli activate distinct combinations of diversely tuned neurons, enabling rich population-level coding.

2013-08-01

We assessed the knowledge of patients with regard to the association between smoking and bladder cancer, and examined the impact of a novel smoking warning label on raising awareness of this issue. We conducted a prospective cross-sectional study involving patients who presented to urology and family practice clinics. A questionnaire was used to assess knowledge regarding the association between smoking and various diseases. Participants were also asked to evaluate a novel smoking warning label for bladder cancer. A total of 291 (97%) patients responded to the questionnaire including 143 (95.3%) at urology clinics and 148 (98.7%) at family practice clinics. Overall only 45.2% of respondents were aware of the association between smoking and bladder cancer compared to 97.4% who knew that there was an association between smoking and lung cancer. There were no significant differences in knowledge between those at urology and family practice clinics. After viewing the warning label, 58.1% of respondents stated that it had changed their opinion on smoking and bladder cancer, and 74.8% felt that this label would be an effective tool to raise awareness of the issue. Patients who changed their opinion had statistically significantly less initial knowledge about the association between smoking and bladder cancer (36.7% vs 57.5% for those who did not change their opinion, p <0.001). Awareness of the link between smoking and bladder cancer remains low. The use of a smoking warning label may help raise awareness of this important public health issue.

Precise fluorescence-guided surgery (FGS) for pancreatic cancer has the potential to greatly improve the outcome in this recalcitrant disease. In order to achieve this goal, we have used genetic reporters to color code cancer and stroma cells in a patient-derived orthotopic xenograft (PDOX) model. The telomerase-dependent green fluorescent protein (GFP) containing adenovirus OBP401 was used to label the cancer cells of the pancreatic cancer PDOX. The PDOX was previously grown in a red fluorescent protein (RFP) transgenic mouse that stably labeled the PDOX stroma cells bright red. The color-coded PDOX model enabled FGS to completely resect the pancreatic tumors including stroma. Dual-colored FGS significantly prevented local recurrence, which bright-light surgery (BLS) or single color could not. FGS, with color-coded cancer and stroma cells has important potential for improving the outcome of recalcitrant cancer. PMID:26088297

Bottlenose dolphins can use learned vocal labels to address each other

PubMed Central

King, Stephanie L.; Janik, Vincent M.

2013-01-01

In animal communication research, vocal labeling refers to incidents in which an animal consistently uses a specific acoustic signal when presented with a specific object or class of objects. Labeling with learned signals is a foundation of human language but is notably rare in nonhuman communication systems. In natural animal systems, labeling often occurs with signals that are not influenced by learning, such as in alarm and food calling. There is a suggestion, however, that some species use learned signals to label conspecific individuals in their own communication system when mimicking individually distinctive calls. Bottlenose dolphins (Tursiops truncatus) are a promising animal for exploration in this area because they are capable of vocal production learning and can learn to use arbitrary signals to report the presence or absence of objects. Bottlenose dolphins develop their own unique identity signal, the signature whistle. This whistle encodes individual identity independently of voice features. The copying of signature whistles may therefore allow animals to label or address one another. Here, we show that wild bottlenose dolphins respond to hearing a copy of their own signature whistle by calling back. Animals did not respond to whistles that were not their own signature. This study provides compelling evidence that a dolphin’s learned identity signal is used as a label when addressing conspecifics. Bottlenose dolphins therefore appear to be unique as nonhuman mammals to use learned signals as individually specific labels for different social companions in their own natural communication system.

A Multi-Label Classification Approach for Coding Cancer Information Service Chat Transcripts

PubMed Central

Rios, Anthony; Vanderpool, Robin; Shaw, Pam

2017-01-01

National Cancer Institute's (NCI) Cancer Information Service (CIS) offers online instant messaging based information service called LiveHelp to patients, family members, friends, and other cancer information consumers. A cancer information specialist (IS) ‘chats’ with a consumer and provides information on a variety of topics including clinical trials. After a LiveHelp chat session is finished, the IS codes about 20 different elements of metadata about the session in electronic contact record forms (ECRF), which are to be later used for quality control and reporting. Besides straightforward elements like age and gender, more specific elements to be coded include the purpose of contact, the subjects of interaction, and the different responses provided to the consumer, the latter two often taking on multiple values. As such, ECRF coding is a time consuming task and automating this process could help ISs to focus more on their primary goal of helping consumers with valuable cancer related information. As a first attempt in this task, we explored multi-label and multi-class text classification approaches to code the purpose, subjects of interaction, and the responses provided based on the chat transcripts. With a sample dataset of about 673 transcripts, we achieved example-based F-scores of 0.67 (for subjects) and 0.58 (responses). We also achieved label-based micro F-scores of 0.65 (for subjects), 0.62 (for responses), and 0.61 (for purpose). To our knowledge this is the first attempt in automatic coding of Live-Help transcripts and our initial results on the smaller corpus indicate promising future directions in this task. PMID:28736775

The practice of menu labeling is gaining popularity worldwide as a potential policy to reduce energy intake as a means to decrease the prevalence of obesity. So the purpose of the present study is to identify the knowledge, attitudes, and practices of adults regarding the implementation of menu labeling in dine-in restaurants. A cross sectional survey included 2020 male or female adults (aged ≥ 18 years old) participants was collected from two cities in the United Arab Emirates(UAE). The participants filled a validated questionnaire in public places in two cities. A chi-squared test was conducted to compare responses for differences in proportions. Most participants were knowledgeable about energy requirements for moderately active men (60%) and women (59%), but underestimated energy requirements for inactive adults (34%). The majority of the respondents favored the requirement to post calorie information on menus of dine-in restaurants at the point of purchase (76%). About half the respondents (48%) were more likely to visit restaurants with labeled menus. The results from this study may form the basis for future strategies in mandating calorie labeling of restaurant menu items in UAE. Menu labeling may be a useful policy tool for promoting appropriate caloric consumption.

2018-03-01

We sought to assess the level of non-compliance with the International Code of Marketing breast-milk substitutes (BMS) and/or Statutory Instrument (SI) Number 48 of 2006 of the Laws of Zambia in two suburbs, Kalingalinga and Chelstone, in Zambia. This was a cross sectional survey. Shop owners (80), health workers (8) and mothers (214) were interviewed. BMS labels and advertisements (62) were observed. The primary outcome was mean non-compliance defined as the number of article violations divided by the total 'obtainable' violations. The score ranges from 0 to 1 with 0 representing no violations in all the articles and one representing violations in all the articles. A total of 62 BMS were assessed. The mean non-compliance score by manufacturers in terms of violations in labelling of BMS was 0.33 (SD = 0.28; 95% CI: 0.26, 0.40). These violations were mainly due to labels containing pictures or graphics representing an infant. 80 shops were also assessed with mean non-compliance score in respect of violations in tie-in-sales, special display, and contact with mothers at the shop estimated as 0.14 (SD = 0.14; 95% CI: 0.11, 0.18). Non-compliance with the Code and/or the local SI is high after 10 years of domesticating the Code.

Neutron-encoded Signatures Enable Product Ion Annotation From Tandem Mass Spectra*

PubMed Central

Richards, Alicia L.; Vincent, Catherine E.; Guthals, Adrian; Rose, Christopher M.; Westphall, Michael S.; Bandeira, Nuno; Coon, Joshua J.

2013-01-01

We report the use of neutron-encoded (NeuCode) stable isotope labeling of amino acids in cell culture for the purpose of C-terminal product ion annotation. Two NeuCode labeling isotopologues of lysine, 13C615N2 and 2H8, which differ by 36 mDa, were metabolically embedded in a sample proteome, and the resultant labeled proteins were combined, digested, and analyzed via liquid chromatography and mass spectrometry. With MS/MS scan resolving powers of ∼50,000 or higher, product ions containing the C terminus (i.e. lysine) appear as a doublet spaced by exactly 36 mDa, whereas N-terminal fragments exist as a single m/z peak. Through theory and experiment, we demonstrate that over 90% of all y-type product ions have detectable doublets. We report on an algorithm that can extract these neutron signatures with high sensitivity and specificity. In other words, of 15,503 y-type product ion peaks, the y-type ion identification algorithm correctly identified 14,552 (93.2%) based on detection of the NeuCode doublet; 6.8% were misclassified (i.e. other ion types that were assigned as y-type products). Searching NeuCode labeled yeast with PepNovo+ resulted in a 34% increase in correct de novo identifications relative to searching through MS/MS only. We use this tool to simplify spectra prior to database searching, to sort unmatched tandem mass spectra for spectral richness, for correlation of co-fragmented ions to their parent precursor, and for de novo sequence identification.

Practical guide to bar coding for patient medication safety.

PubMed

Neuenschwander, Mark; Cohen, Michael R; Vaida, Allen J; Patchett, Jeffrey A; Kelly, Jamie; Trohimovich, Barbara

2003-04-15

Bar coding for the medication administration step of the drug-use process is discussed. FDA will propose a rule in 2003 that would require bar-code labels on all human drugs and biologicals. Even with an FDA mandate, manufacturer procrastination and possible shifts in product availability are likely to slow progress. Such delays should not preclude health systems from adopting bar-code-enabled point-of-care (BPOC) systems to achieve gains in patient safety. Bar-code technology is a replacement for traditional keyboard data entry. The elements of bar coding are content, which determines the meaning; data format, which refers to the embedded data and symbology, which describes the "font" in which the machine-readable code is written. For a BPOC system to deliver an acceptable level of patient protection, the hospital must first establish reliable processes for a patient identification band, caregiver badge, and medication bar coding. Medications can have either drug-specific or patient-specific bar codes. Both varieties result in the desired code that supports patient's five rights of drug administration. When medications are not available from the manufacturer in immediate-container bar-coded packaging, other means of applying the bar code must be devised, including the use of repackaging equipment, overwrapping, manual bar coding, and outsourcing. Virtually all medications should be bar coded, the bar code on the label should be easily readable, and appropriate policies, procedures, and checks should be in place. Bar coding has the potential to be not only cost-effective but to produce a return on investment. By bar coding patient identification tags, caregiver badges, and immediate-container medications, health systems can substantially increase patient safety during medication administration.

Bad-good constraints on a polarity correspondence account for the spatial-numerical association of response codes (SNARC) and markedness association of response codes (MARC) effects.

PubMed

Leth-Steensen, Craig; Citta, Richie

2016-01-01

Performance in numerical classification tasks involving either parity or magnitude judgements is quicker when small numbers are mapped onto a left-sided response and large numbers onto a right-sided response than for the opposite mapping (i.e., the spatial-numerical association of response codes or SNARC effect). Recent research by Gevers et al. [Gevers, W., Santens, S., Dhooge, E., Chen, Q., Van den Bossche, L., Fias, W., & Verguts, T. (2010). Verbal-spatial and visuospatial coding of number-space interactions. Journal of Experimental Psychology: General, 139, 180-190] suggests that this effect also arises for vocal "left" and "right" responding, indicating that verbal-spatial coding has a role to play in determining it. Another presumably verbal-based, spatial-numerical mapping phenomenon is the linguistic markedness association of response codes (MARC) effect whereby responding in parity tasks is quicker when odd numbers are mapped onto left-sided responses and even numbers onto right-sided responses. A recent account of both the SNARC and MARC effects is based on the polarity correspondence principle [Proctor, R. W., & Cho, Y. S. (2006). Polarity correspondence: A general principle for performance of speeded binary classification tasks. Psychological Bulletin, 132, 416-442]. This account assumes that stimulus and response alternatives are coded along any number of dimensions in terms of - and + polarities with quicker responding when the polarity codes for the stimulus and the response correspond. In the present study, even-odd parity judgements were made using either "left" and "right" or "bad" and "good" vocal responses. Results indicated that a SNARC effect was indeed present for the former type of vocal responding, providing further evidence for the sufficiency of the verbal-spatial coding account for this effect. However, the decided lack of an analogous SNARC-like effect in the results for the latter type of vocal responding provides an important constraint on the presumed generality of the polarity correspondence account. On the other hand, the presence of robust MARC effects for "bad" and "good" but not "left" and "right" vocal responses is consistent with the view that such effects are due to conceptual associations between semantic codes for odd-even and bad-good (but not necessarily left-right).

Food Labeling and Consumer Associations with Health, Safety, and Environment.

PubMed

Sax, Joanna K; Doran, Neal

2016-12-01

The food supply is complicated and consumers are increasingly calling for labeling on food to be more informative. In particular, consumers are asking for the labeling of food derived from genetically modified organisms (GMO) based on health, safety, and environmental concerns. At issue is whether the labels that are sought would accurately provide the information desired. The present study examined consumer (n = 181) perceptions of health, safety and the environment for foods labeled organic, natural, fat free or low fat, GMO, or non-GMO. Findings indicated that respondents consistently believed that foods labeled GMO are less healthy, safe and environmentally-friendly compared to all other labels (ps < .05). These results suggest that labels mean something to consumers, but that a disconnect may exist between the meaning associated with the label and the scientific consensus for GMO food. These findings may provide insight for the development of labels that provide information that consumers seek.

In vitro labeling strategies for in cellulo fluorescence microscopy of single ribonucleoprotein machines.

RNA plays a fundamental, ubiquitous role as either substrate or functional component of many large cellular complexes-"molecular machines"-used to maintain and control the readout of genetic information, a functional landscape that we are only beginning to understand. The cellular mechanisms for the spatiotemporal organization of the plethora of RNAs involved in gene expression are particularly poorly understood. Intracellular single-molecule fluorescence microscopy provides a powerful emerging tool for probing the pertinent mechanistic parameters that govern cellular RNA functions, including those of protein coding messenger RNAs (mRNAs). Progress has been hampered, however, by the scarcity of efficient high-yield methods to fluorescently label RNA molecules without the need to drastically increase their molecular weight through artificial appendages that may result in altered behavior. Herein, we employ T7 RNA polymerase to body label an RNA with a cyanine dye, as well as yeast poly(A) polymerase to strategically place multiple 2'-azido-modifications for subsequent fluorophore labeling either between the body and tail or randomly throughout the tail. Using a combination of biochemical and single-molecule fluorescence microscopy approaches, we demonstrate that both yeast poly(A) polymerase labeling strategies result in fully functional mRNA, whereas protein coding is severely diminished in the case of body labeling. © 2016 The Protein Society.

Telepharmacy and bar-code technology in an i.v. chemotherapy admixture area.

PubMed

O'Neal, Brian C; Worden, John C; Couldry, Rick J

2009-07-01

A program using telepharmacy and bar-code technology to increase the presence of the pharmacist at a critical risk point during chemotherapy preparation is described. Telepharmacy hardware and software were acquired, and an inspection camera was placed in a biological safety cabinet to allow the pharmacy technician to take digital photographs at various stages of the chemotherapy preparation process. Once the pharmacist checks the medication vials' agreement with the work label, the technician takes the product into the biological safety cabinet, where the appropriate patient is selected from the pending work list, a queue of patient orders sent from the pharmacy information system. The technician then scans the bar code on the vial. Assuming the bar code matches, the technician photographs the work label, vials, diluents and fluids to be used, and the syringe (before injecting the contents into the bag) along with the vial. The pharmacist views all images as a part of the final product-checking process. This process allows the pharmacist to verify that the correct quantity of medication was transferred from the primary source to a secondary container without being physically present at the time of transfer. Telepharmacy and bar coding provide a means to improve the accuracy of chemotherapy preparation by decreasing the likelihood of using the incorrect product or quantity of drug. The system facilitates the reading of small product labels and removes the need for a pharmacist to handle contaminated syringes and vials when checking the final product.

Selective expression of muscarinic acetylcholine receptor subtype M3 by mouse type III taste bud cells.

PubMed

Mori, Yusuke; Eguchi, Kohgaku; Yoshii, Kiyonori; Ohtubo, Yoshitaka

2016-11-01

Each taste bud cell (TBC) type responds to a different taste. Previously, we showed that an unidentified cell type(s) functionally expresses a muscarinic acetylcholine (ACh) receptor subtype, M3, and we suggested the ACh-dependent modification of its taste responsiveness. In this study, we found that M3 is expressed by type III TBCs, which is the only cell type that possesses synaptic contacts with taste nerve fibers in taste buds. The application of ACh to the basolateral membrane of mouse fungiform TBCs in situ increased the intracellular Ca 2+ concentration in 2.4 ± 1.4 cells per taste bud (mean ± SD, n = 14). After Ca 2+ imaging, we supravitally labeled type II cells (phospholipase C β2 [PLCβ2]-immunoreactive cells) with Lucifer yellow CH (LY), a fluorescent dye and investigated the positional relationship between ACh-responding cells and LY-labeled cells. After fixation, the TBCs were immunohistostained to investigate the positional relationships between immunohistochemically classified cells and LY-labeled cells. The overlay of the two positional relationships obtained by superimposing the LY-labeled cells showed that all of the ACh-responding cells were type III cells (synaptosomal-associated protein 25 [SNAP-25]-immunoreactive cells). The ACh responses required no added Ca 2+ in the bathing solution. The addition of 1 μM U73122, a phospholipase C inhibitor, decreased the magnitude of the ACh response, whereas that of 1 μM U73343, a negative control, had no effect. These results suggest that type III cells respond to ACh and release Ca 2+ from intracellular stores. We also discuss the underlying mechanism of the Ca 2+ response and the role of M3 in type III cells.

World Breastfeeding Week 1994: making the Code work.

PubMed

1994-01-01

WHO adopted the International Code of Marketing of Breastmilk Substitutes in 1981, with the US being the only member voting against it. US abandoned its opposition and voted for the International Code at the World Health Assembly in May 1994. The US was also part of a unanimous vote to promote a resolution that clearly proclaims breast milk to be better than breast milk substitutes and the best food for infants. World Breastfeeding Week 1994 began more efforts to promote the International Code. In 1994, through its Making the Code Work campaign, the World Alliance for Breastfeeding Action (WABA) will work on increasing awareness about the mission and promise of the International Code, notify governments of the Innocenti target date, call for governments to introduce rules and regulations based on the International Code, and encourage public interest groups, professional organizations, and the general public to monitor enforcement of the Code. So far, 11 countries have passed legislation including all or almost all provisions of the International Code. Governments of 36 countries have passed legislation including only some provisions of the International Code. The International Baby Food Action Network (IBFAN), a coalition of more than 140 breastfeeding promotion groups, monitors implementation of the Code worldwide. IBFAN substantiates 1000s of violations of the Code in its report, Breaking the Rules 1994. The violations consist of promoting breast milk substitutes to health workers, using labels describing a brand of formula in idealizing terms, or using labels that do not have warnings in the local language. We should familiarize ourselves with the provisions of the International Code and the status of the Code in our country. WABA provides an action folder which contains basic background information on the code and action ideas.

Pharmacogenomic Biomarkers: an FDA Perspective on Utilization in Biological Product Labeling.

PubMed

Schuck, Robert N; Grillo, Joseph A

2016-05-01

Precision medicine promises to improve both the efficacy and safety of therapeutic products by better informing why some patients respond well to a drug, and some experience adverse reactions, while others do not. Pharmacogenomics is a key component of precision medicine and can be utilized to select optimal doses for patients, more precisely identify individuals who will respond to a treatment and avoid serious drug-related toxicities. Since pharmacogenomic biomarker information can help inform drug dosing, efficacy, and safety, pharmacogenomic data are critically reviewed by FDA staff to ensure effective use of pharmacogenomic strategies in drug development and appropriate incorporation into product labels. Pharmacogenomic information may be provided in drug or biological product labeling to inform health care providers about the impact of genotype on response to a drug through description of relevant genomic markers, functional effects of genomic variants, dosing recommendations based on genotype, and other applicable genomic information. The format and content of labeling for biologic drugs will generally follow that of small molecule drugs; however, there are notable differences in pharmacogenomic information that might be considered useful for biologic drugs in comparison to small molecule drugs. Furthermore, the rapid entry of biologic drugs for treatment of rare genetic diseases and molecularly defined subsets of common diseases will likely lead to increased use of pharmacogenomic information in biologic drug labels in the near future. In this review, we outline the general principles of therapeutic product labeling and discuss the utilization of pharmacogenomic information in biologic drug labels.

Methods of sequencing and detection using energy transfer labels with cyanine dyes as donor chromophores

DOEpatents

Glazer, Alexander N.; Mathies, Richard A.; Hung, Su-Chun; Ju, Jingyue

2000-01-01

This study aims to find out whether front-of-pack nutrition label formats influence the healthfulness of consumers' food choices and important predictors of healthful choices, depending on the size of the choice set that is made available to consumers. The predictors explored were health motivation and perceived capability of making healthful choices. One thousand German and Polish consumers participated in the study that manipulated the format of nutrition labels. All labels referred to the content of calories and four negative nutrients and were presented on savoury and sweet snacks. The different formats included the percentage of guideline daily amount, colour coding schemes, and text describing low, medium and high content of each nutrient. Participants first chose from a set of 10 products and then from a set of 20 products, which was, on average, more healthful than the first choice set. The results showed that food choices were more healthful in the extended 20-product (vs. 10-product) choice set and that this effect is stronger than a random choice would produce. The formats colour coding and texts, particularly colour coding in Germany, increased the healthfulness of product choices when consumers were asked to choose a healthful product, but not when they were asked to choose according to their preferences. The formats did not influence consumers' motivation to choose healthful foods. Colour coding, however, increased consumers' perceived capability of making healthful choices. While the results revealed no consistent differences in the effects between the formats, they indicate that manipulating choice sets by including healthier options is an effective strategy to increase the healthfulness of food choices.

CDSbank: taxonomy-aware extraction, selection, renaming and formatting of protein-coding DNA or amino acid sequences.

PubMed

Hazes, Bart

2014-02-28

Protein-coding DNA sequences and their corresponding amino acid sequences are routinely used to study relationships between sequence, structure, function, and evolution. The rapidly growing size of sequence databases increases the power of such comparative analyses but it makes it more challenging to prepare high quality sequence data sets with control over redundancy, quality, completeness, formatting, and labeling. Software tools for some individual steps in this process exist but manual intervention remains a common and time consuming necessity. CDSbank is a database that stores both the protein-coding DNA sequence (CDS) and amino acid sequence for each protein annotated in Genbank. CDSbank also stores Genbank feature annotation, a flag to indicate incomplete 5' and 3' ends, full taxonomic data, and a heuristic to rank the scientific interest of each species. This rich information allows fully automated data set preparation with a level of sophistication that aims to meet or exceed manual processing. Defaults ensure ease of use for typical scenarios while allowing great flexibility when needed. Access is via a free web server at http://hazeslab.med.ualberta.ca/CDSbank/. CDSbank presents a user-friendly web server to download, filter, format, and name large sequence data sets. Common usage scenarios can be accessed via pre-programmed default choices, while optional sections give full control over the processing pipeline. Particular strengths are: extract protein-coding DNA sequences just as easily as amino acid sequences, full access to taxonomy for labeling and filtering, awareness of incomplete sequences, and the ability to take one protein sequence and extract all synonymous CDS or identical protein sequences in other species. Finally, CDSbank can also create labeled property files to, for instance, annotate or re-label phylogenetic trees.

How Mood and Task Complexity Affect Children's Recognition of Others’ Emotions

PubMed Central

Cummings, Andrew J.; Rennels, Jennifer L.

2013-01-01

Previous studies examined how mood affects children's accuracy in matching emotional expressions and labels (label-based tasks). This study was the first to assess how induced mood (positive, neutral, or negative) influenced 5- to 8-year-olds’ accuracy and reaction time using both context-based tasks, which required inferring a character's emotion from a vignette, and label-based tasks. Both tasks required choosing one of four facial expressions to respond. Children responded more accurately to label-based questions relative to context-based questions at 5 to 7 years of age, but showed no differences at 8 years of age, and when the emotional expression being identified was happiness, sadness, or surprise, but not disgust. For the context-based questions, children were more accurate at inferring sad and disgusted emotions compared to happy and surprised emotions. Induced positive mood facilitated 5-year-olds’ processing (decreased reaction time) in both tasks compared to induced negative and neutral moods. Results demonstrate how task type and children's mood influence children's emotion processing at different ages. PMID:24489442

Leaky gate model: intensity-dependent coding of pain and itch in the spinal cord

2017-01-01

SUMMARY Coding of itch versus pain has been heatedly debated for decades. However, the current coding theories (labeled line, intensity and selectivity theory) cannot accommodate all experimental observations. Here we identified a subset of spinal interneurons, labeled by gastrin releasing peptide (Grp), that receive direct synaptic input from both pain and itch primary sensory neurons. When activated, these Grp+ neurons generated rarely-seen simultaneous robust pain and itch responses that were intensity-dependent. Accordingly, we propose a “leaky gate” model, in which Grp+ neurons transmit both itch and weak pain signals, however upon strong painful stimuli the recruitment of endogenous opioids works to close this gate, reducing overwhelming pain generated by parallel pathways. Consistent with our model, loss of these Grp+ neurons increased pain responses while itch was decreased. Our new model serves as an example of non-monotonic coding in the spinal cord and better explains observations in human psychophysical studies. PMID:28231466

This study examined rates of awareness of standard drink labelling and drinking guidelines among Australian adult drinkers. Demographic predictors of these two outcomes were also explored. Online survey panel participants aged 18-45 years(n = 1061; mean age = 33.2 years) completed an online survey assessing demographics, alcohol consumption patterns, awareness of standard drink labels and the National Health and Medical Research Council (NHMRC) guidelines, and support for more detailed labels. The majority (80%) of participants had seen standard drink labels on alcohol products; with younger drinkers, those from a regional/rural location and high-risk drinkers significantly more likely to have seen such labelling. Most respondents estimated at or below the maximum number of drinks stipulated in the NHMRC guidelines. However, their estimates of the levels for male drinkers were significantly higher than for female drinkers. High-risk drinkers were significantly less likely to provide accurate estimates, while those who had seen the standard drink logo were significantly more likely to provide accurate estimates of drinking levels to reduce the risk of long-term harms only. Just under three-quarters of respondents supported the inclusion of more information on labels regarding guidelines to reduce negative health effects. The current standard drink labelling approach fails to address high-risk drinkers. The inclusion of information about NHMRC guidelines on alcohol labels, and placing standard drink labelling on the front of products could improve awareness of what constitutes a standard drink and safe levels of consumption among Australian drinkers.[Kerri Coomber, Sandra C.

Introduction: The Guidelines for the implementation of Article 11 of the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) require that cigarette health warning labels should include pictures and take up 50% or more of the principal display area. This study examined how the association between large pictorial warnings, those covering ≥50% of the front and back of the package, and the prevalence of cigarette smoking varies by educational attainment. Methods: We pooled individual-level tobacco use data from the Global Adult Tobacco Survey (GATS) in 18 countries between 2008 and 2013 and linked them with warning label requirements during the same period from the MPOWER database and reports regarding warnings. The respondents’ self-reported exposure to warnings was examined according to education. Logistic regressions were further employed to analyze education-specific associations between large pictorial warnings and smoking prevalence, and whether such association differed by education was examined using an interaction test. Results: At the time of the survey, eight out of 18 countries had imposed graphic warning labels that covered ≥50% of the package. These warnings were associated with a 10.0% (OR = 0.89; 95% CI: 0.81, 0.97; p ≤ 0.01) lower cigarette smoking prevalence among adults with less than a secondary education or no formal education, but not among respondents with at least a secondary education. Less educated respondents were also less likely to be exposed to warnings in all 18 countries. The association between strong warnings and lower smoking prevalence among less educated respondents could be greater if their exposure to warnings increases. Conclusions: Prominent pictorial warning labels can potentially reduce health disparities resulting from smoking across different education levels. PMID:28117729

Traditional manual sorting operation is not suitable for the development of Chinese logistics. For better sorting packages, a QR code recognition technology is proposed to identify the QR code label on the packages in package auto-sorting system. The experimental results compared with other algorithms in literatures demonstrate that the proposed method is valid and its performance is superior to other algorithms.

The process of electrode localization, labeling, and warping for use in ECoG currently varies widely across laboratories, and it is usually performed with custom, lab-specific code. This python package aims to provide a standardized interface for these procedures, as well as code to plot and display results on 3D cortical surface meshes. It gives the user an easy interface to create anatomically labeled electrodes that can also be warped to an atlas brain, starting with only a preoperative T1 MRI scan and a postoperative CT scan. We describe the full capabilities of our imaging pipeline and present a step-by-step protocol for users.

To describe the prevalence of prescribing against-label statin-fibrate combination therapy. Retrospective cohort study. Medstat MarketScan Commercial Claims and Encounter database. Adults (aged 18-89 yrs) who were prescribed statin-fibrate combination therapy between January 1, 2003, and June 30, 2009, had pharmacy claims demonstrating two or more concurrently filled prescriptions for a statin and a fibrate, and had continuous insurance enrollment for at least 12 months. Claims data were used to identify patients with dyslipidemia based on International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes. National Drug Codes were used to describe concurrent statin-fibrate combination therapy. The primary outcome was recent use of against-label statin-fibrate combination therapy, defined as use during the last 18 months (January 1, 2008-June 30, 2009) of the study period. Patients were stratified according to statin and dosage to identify against-label combination use (e.g., simvastatin > 10 mg/day with gemfibrozil). Within the recent-use period, 131,394 patients were prescribed concurrent statin-fibrate combination therapy; of these patients, 13,420 (10.2%) had against-label therapy. Simvastatin-gemfibrozil accounted for 8978 (66.9%) of all against-label combinations. Of all 9877 simvastatin-gemfibrozil combinations prescribed in the recent-use period (both on-label and against-label use), 8978 (90.9%) were against label. The secondary outcome was prevalence of against-label statin-fibrate combination therapy on an annual basis: 15.5% in 2003, 18.7% in 2004, 9.1% in 2005, 8.3% in 2006, 9.2% in 2007, and 9.8% in 2008. Against-label statin-fibrate combination therapy continues to be prescribed despite established United States Food and Drug Administration (FDA) dose restrictions. Nearly every time the simvastatin-gemfibrozil combination was prescribed, it was against label because simvastatin exceeded the maximum dose restriction. Updated simvastatin labeling in June 2011 includes additional maximum dose restrictions and new contraindications, which include gemfibrozil. Different approaches in clinical practice are needed to ensure adherence with the revised FDA labeling. © 2012 Pharmacotherapy Publications, Inc. All rights reserved.

Psychotherapy represents a broad class of medical interventions received by millions of patients each year. Unlike most medical treatments, its primary mechanisms are linguistic; i.e., the treatment relies directly on a conversation between a patient and provider. However, the evaluation of patient-provider conversation suffers from critical shortcomings, including intensive labor requirements, coder error, nonstandardized coding systems, and inability to scale up to larger data sets. To overcome these shortcomings, psychotherapy analysis needs a reliable and scalable method for summarizing the content of treatment encounters. We used a publicly available psychotherapy corpus from Alexander Street press comprising a large collection of transcripts of patient-provider conversations to compare coding performance for two machine learning methods. We used the labeled latent Dirichlet allocation (L-LDA) model to learn associations between text and codes, to predict codes in psychotherapy sessions, and to localize specific passages of within-session text representative of a session code. We compared the L-LDA model to a baseline lasso regression model using predictive accuracy and model generalizability (measured by calculating the area under the curve (AUC) from the receiver operating characteristic curve). The L-LDA model outperforms the lasso logistic regression model at predicting session-level codes with average AUC scores of 0.79, and 0.70, respectively. For fine-grained level coding, L-LDA and logistic regression are able to identify specific talk-turns representative of symptom codes. However, model performance for talk-turn identification is not yet as reliable as human coders. We conclude that the L-LDA model has the potential to be an objective, scalable method for accurate automated coding of psychotherapy sessions that perform better than comparable discriminative methods at session-level coding and can also predict fine-grained codes.

Principal cells of the brainstem's interaural sound level detector are temporal differentiators rather than integrators.

PubMed

2018-06-14

The brainstem's lateral superior olive (LSO) is thought to be crucial for localizing high-frequency sounds by coding interaural sound level differences (ILD). Its neurons weigh contralateral inhibition against ipsilateral excitation, making their firing rate a function of the azimuthal position of a sound source. Since the very first in vivo recordings, LSO principal neurons have been reported to give sustained and temporally integrating 'chopper' responses to sustained sounds. Neurons with transient responses were observed but largely ignored and even considered a sign of pathology. Using the Mongolian gerbil as a model system, we have obtained the first in vivo patch clamp recordings from labeled LSO neurons and find that principal LSO neurons, the most numerous projection neurons of this nucleus, only respond at sound onset and show fast membrane features suggesting an importance for timing. These results provide a new framework to interpret previously puzzling features of this circuit. © 2018, Franken et al.

Unsafe working practices, working environments, disposable waste products, and chemicals in clinical laboratories contribute to infectious and non-infectious hazards. Staffs, the community, and patients are less safe. Furthermore, such practices compromise the quality of laboratory services. We conducted a study to describe safety practices in public hospital laboratories of Oromia Regional State, Ethiopia. Randomly selected ten public hospital laboratories in Oromia Regional State were studied from Oct 2011- Feb 2012. Self-administered structured questionnaire and observation checklists were used for data collection. The respondents were heads of the laboratories, senior technicians, and safety officers. The questionnaire addressed biosafety label, microbial hazards, chemical hazards, physical/mechanical hazards, personal protective equipment, first aid kits and waste disposal system. The data was analyzed using descriptive analysis with SPSS version16 statistical software. All of the respondents reported none of the hospital laboratories were labeled with the appropriate safety label and safety symbols. These respondents also reported they may contain organisms grouped under risk group IV in the absence of microbiological safety cabinets. Overall, the respondents reported that there were poor safety regulations or standards in their laboratories. There were higher risks of microbial, chemical and physical/mechanical hazards. Laboratory safety in public hospitals of Oromia Regional State is below the standard. The laboratory workers are at high risk of combined physical, chemical and microbial hazards. Prompt recognition of the problem and immediate action is mandatory to ensure safe working environment in health laboratories.

In the case of medication errors which are among the more frequent adverse events that occur in the hospital, there is a need for effective measures to prevent incidence. According to the Japan Society of Anesthesiologists study "Drug incident investigation 2005-2007 years", "Error of a syringe at the selection stage" was the most frequent (44.2%). The status of current measures and best practices implemented in Japanese hospitals was the focus of a subsequent investigation. Representative specialists in anesthesiology certified hospitals across the country were surveyed via a questionnaire sampling that lasted 46 days. Investigation method was via the Web with survey responses anonymous. With respect to preventive measures implemented to mitigate risk of medication errors in perioperative settings, responses included: incident and accident report (215 facilities, 70.3%), use of pre-filled syringes (180 facilities, 58.8%), devised the arrangement of dangerous drugs (154 facilities, 50.3%), use of the product with improper connection preventing mechanism (123 facilities, 40.2%), double-check (116 facilities, 37.9%), use of color barreled syringe (115 facilities, 37.6%), use of color label or color tape (89 facilities, 29.1%), presentation of medication such as placing the ampoule or syringe on a tray by dividing color code for drug class on a tray (54 facilities, 17.6%), the discontinuance of handwritten labels (23 facilities, 7.5%), use of a drug verification system that uses bar code (20 facilities, 6.5%), and facilities that have not implemented any means (11 facilities, 3.6%), others not mentioned (10 facilities, 3.3%), and use of carts that count/account the agents by drug type and record selection and number picked automatically (6 facilities, 2.0%). Drug name identification affixed to the syringe via perforated label torn from the ampoule/vial, etc. (245 facilities, 28.1%), handwriting directly to the syringe (208 facilities, 23.8%), use of the attached label (like that comes with the product) (187 facilities, 21.4%), handwriting on the plain tape (87 facilities, 10.0%), printing labels (62 facilities, 7.1%), printed color labels (44 facilities, 5.0%), handwriting on the color tape (27 facilities, 3.1%), machinery for printing the drug name by scanning bar code of the ampoule, etc.(10 facilities, 1.1%), others (3 facilities, 0.3%), no description on the prepared drug (0 facilities, 0%). The awareness of international standard color code, such as by the International Organization for Standardization (ISO), was only 18.6%. Targeting anesthesiology certified hospitals recognized by the Japan Society of Anesthesiologists, the result of the survey on the measures to prevent medication errors during perioperative procedures indicated that various measures were documented in use. However, many facilities still use hand written labels (a common cause for errors). Confirmation of the need for improved drug name and drug recognition on syringe was documented.

In recent years, governments, policy-makers, and managers of private food companies and agribusinesses are interested in understanding how consumers will react to environmentally sustainable attributes and information on food product labels. This study examines consumers' stated preferences for water and carbon footprints labelled food products from the viewpoint of black and white South Africans. Discrete choice experimental data was collected from black and white consumers to possibly assess cross-ethnic variations in preferences for environmentally sustainable products. Two widely purchased livestock products were chosen for the choice experiment. We found that consumers' preferences for environmentally sustainable attributes vary significantly between black and white South Africans. Our findings revealed that there are profound heterogeneous consumer segments within black and white respondents. The heterogeneity within both sub-samples is better explained at the segment level, rather than at individual level. For both product categories, the findings revealed that there are more distinct consumer segments among black respondents, relative to white respondents. The black respondents consist of water sustainability advocates, carbon reduction advocates, keen environmentalist and environmental neutrals. The white respondents entail keen environmentalist, environmental cynics, and environmental neutrals. The inherent significant variations in preferences for environmentally sustainable attributes across segments and racial groups would help in formulating feasible, and segment-specific environmental sustainability policies and marketing strategies aimed at changing consumers' attitude towards environmentally sustainable products. Demographic targeting of consumer segments, sustainability awareness and segment-specific educational campaigns meant to enhance subjective and objective knowledge on environmental sustainability are important tools for food companies and agribusinesses to promote and market environmentally sustainable food products.

This paper investigates the constellation and mapping optimization for amplitude phase shift keying (APSK) modulation, which is deployed in Digital Video Broadcasting Satellite - Second Generation (DVB-S2) and Digital Video Broadcasting - Satellite services to Handhelds (DVB-SH) broadcasting standards due to its merits of power and spectral efficiency together with the robustness against nonlinear distortion. The mapping optimization is performed for 32-APSK according to combined cost functions related to Euclidean distance and mutual information. A Binary switching algorithm and its modified version are used to minimize the cost function and the estimated error between the original and received data. The optimized constellation mapping is tested by combining DVB-S2 standard Low-Density Parity-Check (LDPC) codes in both Bit-Interleaved Coded Modulation (BICM) and BICM with iterative decoding (BICM-ID) systems. The simulated results validate the proposed constellation labeling optimization scheme which yields better performance against conventional 32-APSK constellation defined in DVB-S2 standard.

Multimodal Discriminative Binary Embedding for Large-Scale Cross-Modal Retrieval.

2016-10-01

Multimodal hashing, which conducts effective and efficient nearest neighbor search across heterogeneous data on large-scale multimedia databases, has been attracting increasing interest, given the explosive growth of multimedia content on the Internet. Recent multimodal hashing research mainly aims at learning the compact binary codes to preserve semantic information given by labels. The overwhelming majority of these methods are similarity preserving approaches which approximate pairwise similarity matrix with Hamming distances between the to-be-learnt binary hash codes. However, these methods ignore the discriminative property in hash learning process, which results in hash codes from different classes undistinguished, and therefore reduces the accuracy and robustness for the nearest neighbor search. To this end, we present a novel multimodal hashing method, named multimodal discriminative binary embedding (MDBE), which focuses on learning discriminative hash codes. First, the proposed method formulates the hash function learning in terms of classification, where the binary codes generated by the learned hash functions are expected to be discriminative. And then, it exploits the label information to discover the shared structures inside heterogeneous data. Finally, the learned structures are preserved for hash codes to produce similar binary codes in the same class. Hence, the proposed MDBE can preserve both discriminability and similarity for hash codes, and will enhance retrieval accuracy. Thorough experiments on benchmark data sets demonstrate that the proposed method achieves excellent accuracy and competitive computational efficiency compared with the state-of-the-art methods for large-scale cross-modal retrieval task.

QR (Quick Response) codes are two-dimensional barcodes composed of special geometric patterns of black modules in a white square background that can encode different types of information with high density and robustness, correct errors and physical damages, thus keeping the stored information protected. Recently, these codes have gained increased attention as they offer a simple physical tool for quick access to Web sites for advertising and social interaction. Challenges encompass the increase of the storage capacity limit, even though they can store approximately 350 times more information than common barcodes, and encode different types of characters (e.g., numeric, alphanumeric, kanji and kana). In this work, we fabricate luminescent QR codes based on a poly(methyl methacrylate) substrate coated with organic-inorganic hybrid materials doped with trivalent terbium (Tb3+) and europium (Eu3+) ions, demonstrating the increase of storage capacity per unit area by a factor of two by using the colour multiplexing, when compared to conventional QR codes. A novel methodology to decode the multiplexed QR codes is developed based on a colour separation threshold where a decision level is calculated through a maximum-likelihood criteria to minimize the error probability of the demultiplexed modules, maximizing the foreseen total storage capacity. Moreover, the thermal dependence of the emission colour coordinates of the Eu3+/Tb3+-based hybrids enables the simultaneously QR code colour-multiplexing and may be used to sense temperature (reproducibility higher than 93%), opening new fields of applications for QR codes as smart labels for sensing.

To assess the state of readiness for the adoption of paperless labeling among a nationally representative sample of pharmacies, including chain pharmacies, independent retail pharmacies, hospitals, and other rural or urban dispensing sites. Both quantitative and qualitative analyses were used to analyze responses to a cross-sectional survey disseminated to American Pharmacists Association pharmacists nationwide. The survey assessed factors related to pharmacists' attitudinal readiness (ie, perceptions of impact) and pharmacies' structural readiness (eg, availability of electronic resources, internet access) for the paperless labeling initiative. We received a total of 436 survey responses (6% response rate) from pharmacists representing 44 US states and territories. Across the spectrum of settings we studied, pharmacists had work access to computers, printers, fax machines and access to the internet or intranet. Approximately 79% of respondents believed that the initiative would improve the adequacy of drug information available in their work site and 95% believed it would either not change (33%) or would improve (62%) communication to patients. Overall, respondents' comments supported advancing the initiative; however, some comments revealed reservations regarding corporate or pharmacy buy-in, success of implementation, and ease of adoption. This is the first nationwide study to report about pharmacists' perspectives on paperless labeling. In general, pharmacists believe they are ready and that their pharmacies are well equipped for the transition to paperless labeling. Further exploration of perspectives from product label manufacturers and corporate pharmacy offices is needed to understand fully what will be necessary to complete this transition.

TRIAD IV: Nationwide Survey of Medical Students' Understanding of Living Wills and DNR Orders.

2016-12-01

Living wills are a form of advance directives that help to protect patient autonomy. They are frequently encountered in the conduct of medicine. Because of their impact on care, it is important to understand the adequacy of current medical school training in the preparation of physicians to interpret these directives. Between April and August 2011 of third and fourth year medical students participated in an internet survey involving the interpretation of living wills. The survey presented a standard living will as a "stand-alone," a standard living will with the addition an emergent clinical scenario and then variations of the standard living will that included a code status designation ("DNR," "Full Code," or "Comfort Care"). For each version/ scenario, respondents were asked to assign a code status and choose interventions based on the cases presented. Four hundred twenty-five students from medical schools throughout the country responded. The majority indicated they had received some form of advance directive training and understood the concept of code status and the term "DNR." Based on a stand-alone document, 15% of respondents correctly denoted "full code" as the appropriate code status; adding a clinical scenario yielded negligible improvement. When a code designation was added to the living will, correct code status responses ranged from 68% to 93%, whereas correct treatment decisions ranged from 18% to 78%. Previous training in advance directives had no impact on these results. Our data indicate that the majority of students failed to understand the key elements of a living will; adding a code status designations improved correct responses with the exception of the term DNR. Misunderstanding of advance directives is a nationwide problem and jeopardizes patient safety. Medical School ethics curricula need to be improved to ensure competency with respect to understanding advance directives.

Orthographic Coding: Brain Activation for Letters, Symbols, and Digits.

The present experiment investigates the input coding mechanisms of 3 common printed characters: letters, numbers, and symbols. Despite research in this area, it is yet unclear whether the identity of these 3 elements is processed through the same or different brain pathways. In addition, some computational models propose that the position-in-string coding of these elements responds to general flexible mechanisms of the visual system that are not character-specific, whereas others suggest that the position coding of letters responds to specific processes that are different from those that guide the position-in-string assignment of other types of visual objects. Here, in an fMRI study, we manipulated character position and character identity through the transposition or substitution of 2 internal elements within strings of 4 elements. Participants were presented with 2 consecutive visual strings and asked to decide whether they were the same or different. The results showed: 1) that some brain areas responded more to letters than to numbers and vice versa, suggesting that processing may follow different brain pathways; 2) that the left parietal cortex is involved in letter identity, and critically in letter position coding, specifically contributing to the early stages of the reading process; and that 3) a stimulus-specific mechanism for letter position coding is operating during orthographic processing. © The Author 2014.

Pharmaceutical Industry Off-label Promotion and Self-regulation: A Document Analysis of Off-label Promotion Rulings by the United Kingdom Prescription Medicines Code of Practice Authority 2003–2012

PubMed Central

Vilhelmsson, Andreas; Davis, Courtney; Mulinari, Shai

Background European Union law prohibits companies from marketing drugs off-label. In the United Kingdom—as in some other European countries, but unlike the United States—industry self-regulatory bodies are tasked with supervising compliance with marketing rules. The objectives of this study were to (1) characterize off-label promotion rulings in the UK compared to the whistleblower-initiated cases in the US and (2) shed light on the UK self-regulatory mechanism for detecting, deterring, and sanctioning off-label promotion. Methods and Findings We conducted structured reviews of rulings by the UK self-regulatory authority, the Prescription Medicines Code of Practice Authority (PMCPA), between 2003 and 2012. There were 74 off-label promotion rulings involving 43 companies and 65 drugs. Nineteen companies were ruled in breach more than once, and ten companies were ruled in breach three or more times over the 10-y period. Drawing on a typology previously developed to analyse US whistleblower complaints, we coded and analysed the apparent strategic goals of each off-label marketing scheme and the practices consistent with those alleged goals. 50% of rulings cited efforts to expand drug use to unapproved indications, and 39% and 38% cited efforts to expand beyond approved disease entities and dosing strategies, respectively. The most frequently described promotional tactic was attempts to influence prescribers (n = 72, 97%), using print material (70/72, 97%), for example, advertisements (21/70, 30%). Although rulings cited prescribers as the prime target of off-label promotion, competing companies lodged the majority of complaints (prescriber: n = 16, 22%, versus companies: n = 42, 57%). Unlike US whistleblower complaints, few UK rulings described practices targeting consumers (n = 3, 4%), payers (n = 2, 3%), or company staff (n = 2, 3%). Eight UK rulings (11%) pertaining to six drugs described promotion of the same drug for the same off-label use as was alleged by whistleblowers in the US. However, while the UK cases typically related to only one or a few claims made in printed material, several complaints in the US alleged multifaceted and covert marketing activities. Because this study is limited to PMCPA rulings and whistleblower-initiated federal cases, it may offer a partial view of exposed off-label marketing. Conclusion The UK self-regulatory system for exposing marketing violations relies largely on complaints from company outsiders, which may explain why most off-label promotion rulings relate to plainly visible promotional activities such as advertising. This contrasts with the US, where Department of Justice investigations and whistleblower testimony have alleged complex off-label marketing campaigns that remain concealed to company outsiders. UK authorities should consider introducing increased incentives and protections for whistleblowers combined with US-style governmental investigations and meaningful sanctions. UK prescribers should be attentive to, and increasingly report, off-label promotion. PMID:26812151

Human Emotion Experiences Can Be Predicted on Theoretical Grounds: Evidence from Verbal Labeling

PubMed Central

Scherer, Klaus R.; Meuleman, Ben

2013-01-01

In an effort to demonstrate that the verbal labeling of emotional experiences obeys lawful principles, we tested the feasibility of using an expert system called the Geneva Emotion Analyst (GEA), which generates predictions based on an appraisal theory of emotion. Several thousand respondents participated in an Internet survey that applied GEA to self-reported emotion experiences. Users recalled appraisals of emotion-eliciting events and labeled the experienced emotion with one or two words, generating a massive data set on realistic, intense emotions in everyday life. For a final sample of 5969 respondents we show that GEA achieves a high degree of predictive accuracy by matching a user’s appraisal input to one of 13 theoretically predefined emotion prototypes. The first prediction was correct in 51% of the cases and the overall diagnosis was considered as at least partially correct or appropriate in more than 90% of all cases. These results support a component process model that encourages focused, hypothesis-guided research on elicitation and differentiation, memory storage and retrieval, and categorization and labeling of emotion episodes. We discuss the implications of these results for the study of emotion terms in natural language semantics. PMID:23483988

Lifestyle behaviours among adults reporting awareness of Canada's Food Guide (CFG) are described. Data from a cross-sectional survey of adults from Alberta were used to estimate the prevalence of reported health behaviours among respondents aware of the CFG. Respondents (n = 1044) reported general awareness of CFG (mean age 50.3 years; 54.2% female) of whom 82.2% reported awareness of specific CFG recommendations. Respondents reported frequently reading food labels (>58.0%), reading the number of calories (45.5%), the amount of sodium (49.5%), the amount of fat (46.7%), and the type of fat (45.5%) on the food label. Most respondents (90.0%) reported frequently selecting foods to promote health. Approximately one-third of the respondents (35.8%) reported frequently consuming ≥5 portions of vegetables and fruit per day and regularly participating in physical activity (55.3%). Body weight was perceived as healthy by 63.4% of the respondents. Most engaged in 2 health behaviours frequently. Adjusting for important socio-demographic characteristics, those who reported frequently consuming ≥5 portions of vegetables and fruit per day were more likely to engage in a second health behaviour outlined in CGF (OR: 23.6, 95% CI (16.2-34.4)). Awareness of CFG did not translate to positive health behaviours. More proactive population level strategies to support specific health behaviours as outlined in CFG might be warranted.

This article discusses the usability of an interactive application for halal products using Optical Character Recognition (OCR) and Augmented Reality (AR) technologies. Among the problems that have been identified in this study is that consumers have little knowledge about the E-Code. Therefore, users often have doubts about the halal status of the product. Nowadays, the integrity of halal status can be doubtful due to the actions of some irresponsible people spreading false information about a product. Therefore, an application that uses OCR and AR technology developed in this study will help the users to identify the information content of a product by scanning the E-Code label and by scanning the product's brand to know the halal status of the product. In this application, E-Code on the label of a product is scanned using OCR technology to display information about the E-Code. The product's brand is scan using augmented reality technology to display halal status of the product. The findings reveal that users are satisfied with this application and it is useful and easy to use.

A comparative review is presented of available technologies suitable for automatic reading of patient identification bracelet tags. Existing technologies' backgrounds, characteristics, advantages and disadvantages, are described in relation to their possible use by public health care centers with budgetary limitations. A comparative assessment is presented of suitable automatic identification systems based on graphic codes, both one- (1D) and two-dimensional (2D), printed on labels, as well as those based on radio frequency identification (RFID) tags. The analysis looks at the tradeoffs of these technologies to provide guidance to hospital administrator looking to deploy patient identification technology. The results suggest that affordable automatic patient identification systems can be easily and inexpensively implemented using 2D code printed on low cost bracelet labels, which can then be read and automatically decoded by ordinary mobile smart phones. Because of mobile smart phones' present versatility and ubiquity, the implantation and operation of 2D code, and especially Quick Response® (QR) Code, technology emerges as a very attractive alternative to automate the patients' identification processes in low-budget situations.

Supervised Extraction of Diagnosis Codes from EMRs: Role of Feature Selection, Data Selection, and Probabilistic Thresholding.

PubMed

Rios, Anthony; Kavuluru, Ramakanth

2013-09-01

Extracting diagnosis codes from medical records is a complex task carried out by trained coders by reading all the documents associated with a patient's visit. With the popularity of electronic medical records (EMRs), computational approaches to code extraction have been proposed in the recent years. Machine learning approaches to multi-label text classification provide an important methodology in this task given each EMR can be associated with multiple codes. In this paper, we study the the role of feature selection, training data selection, and probabilistic threshold optimization in improving different multi-label classification approaches. We conduct experiments based on two different datasets: a recent gold standard dataset used for this task and a second larger and more complex EMR dataset we curated from the University of Kentucky Medical Center. While conventional approaches achieve results comparable to the state-of-the-art on the gold standard dataset, on our complex in-house dataset, we show that feature selection, training data selection, and probabilistic thresholding provide significant gains in performance.

Permethrin spot-on intoxication of cats Literature review and survey of veterinary practitioners in Australia.

2010-01-01

SURVEY AIMS: A questionnaire was sent to veterinarians in Australia to determine the approximate number of cats presenting for permethrin spot-on (PSO) intoxication over a 2-year period. Of the 269 questionnaires returned, 255 were eligible for analysis. A total of 207 respondents (81%) reported cases of PSO intoxication in cats over the previous 2 years. In total, 750 individual cases were reported, with 166 deaths. While all deaths were generally attributable to intoxication, 39 cats were euthanased because owners were unable to pay the anticipated treatment costs. Brands of PSO implicated included Exelpet Flea (and Tick) Liquidator (Mars Australia) (146 respondents), Bayer Advantix (48), Purina Totalcare Flea Eliminator Line-On (19), Troy Ease-On (six) and Duogard Line-On (Virbac) (four); 67 respondents were not able to identify a specific product. Permethrin spot-on formulations were most commonly obtained from supermarkets (146 respondents), followed by pet stores (43), veterinary practices (16), and a range of other sources including produce stores and friends. The majority of intoxication cases reported involved PSOs labelled for use in dogs with specific label instructions such as 'toxic to cats'. Owners applied these PSO products to their cats accidentally or intentionally. In some cases, exposure was through secondary contact, such as when a PSO product was applied to a dog with which a cat had direct or indirect contact. In the authors' view, because of the likelihood of inappropriate use and toxicity in the non-labelled species, over-the-counter products intended for use in either dogs or cats must have a high margin of safety in all species. Furthermore, PSOs should only be available at points of sale where veterinary advice can be provided and appropriate warnings given. As an interim measure, modified labelling with more explicit warnings may reduce morbidity and mortality. Copyright 2009 ESFM and AAFP. Published by Elsevier Ltd. All rights reserved.

Male discrimination of receptive and unreceptive female calls by temporal features

PubMed Central

Elliott, Taffeta M.; Kelley, Darcy B.

2012-01-01

Summary In murky, crowded ponds in South Africa, female clawed frogs, Xenopus laevis (Daudin), vocalize to signal reproductive state. Female calls consist of acoustically similar clicks delivered in trains with characteristic rates. The rapping call of a sexually receptive female has a more rapid click rate [81 ms mean interclick interval (ICI)] than the ticking call of an unreceptive female (219 ms ICI). Rapping stimulates male advertisement calling, whereas ticking suppresses an already calling male. We examined how males label and discriminate female click rates. A labeling boundary experiment revealed that males perceive click rates between the means of rapping and ticking as lying on a continuum. They respond to 98 and 160 ms ICI as though to rapping and ticking, respectively. However, calling evoked by a click rate equally common to both calls (120 ms ICI) did not differ from the response to either rapping or ticking. A second experiment evaluated whether males discriminate click rates both labeled as ticking (180 and 219 ms ICI). Ticking suppresses advertising males, and suppressed males habituate (resume calling) to prolonged ticking. Both ticking stimuli suppressed males with equal effectiveness, and males habituated in equivalent amounts of time. When the stimulus was switched during habituation, no dishabituation occurred. We conclude that male labeling of click trains as rapping or ticking reflects an ambiguity resulting from the overlap in ICIs naturally occurring in the calls. Males do not respond differentially to click rates within the ticking category. Males thus combine discriminating and non-discriminating strategies in responding to the salient feature of female calls. PMID:17690231

The ban on "off-label" pharmaceutical promotion: constitutionally permissible prophylaxis against false or misleading commercial speech?

PubMed

Greenwood, Kate

2011-01-01

Critics of the Food & Drug Administration's ban on off-label promotion often claim that it violates the First Amendment because it suppresses pharmaceutical manufacturers' truthful speech about their legal--and beneficial--products. Characterizing the ban on off-label promotion in this way has more than rhetorical significance. Bans on truthful, non-misleading speech elicit special skepticism because of the belief that they "usually rest solely on the offensive assumption that the public will respond 'irrationally' to the truth." The legislative history of the provisions of the Food Drug and Cosmetic Act that underlie the ban on off-label promotion, however, reveals that Congress was concerned that physicians were responding rationally to false and misleading promotional claims. In this Article, I explore the doctrinal questions raised by conceiving of the ban on off-label promotion not as a ban on "truthful speech to physicians" but instead as a prophylaxis against false and misleading pharmaceutical promotion. I review the evidence that false and misleading claims were commonplace before the ban's adoption and persist today, along with the enforcement challenges the FDA confronted at that time and would confront were the ban lifted, and conclude the government likely could develop the factual record necessary to establish that Congress' rejection of an after-the-fact case-by-case approach to combating false and misleading prescription drug promotion is constitutional.

Cytokines play important roles in the immune system and have been regarded as biomarkers. While single cytokine is not specific and accurate enough to meet the strict diagnosis in practice, in this work, we constructed a multiplexed detection method for cytokines based on dual bar-code strategy and single-molecule counting. Taking interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) as model analytes, first, the magnetic nanobead was functionalized with the second antibody and primary bar-code strands, forming a magnetic nanoprobe. Then, through the specific reaction of the second antibody and the antigen that fixed by the primary antibody, sandwich-type immunocomplex was formed on the substrate. Next, the primary bar-code strands as amplification units triggered multibranched hybridization chain reaction (mHCR), producing nicked double-stranded polymers with multiple branched arms, which were served as secondary bar-code strands. Finally, the secondary bar-code strands hybridized with the multimolecule labeled fluorescence probes, generating enhanced fluorescence signals. The numbers of fluorescence dots were counted one by one for quantification with epi-fluorescence microscope. By integrating the primary and secondary bar-code-based amplification strategy and the multimolecule labeled fluorescence probes, this method displayed an excellent sensitivity with the detection limits were both 5 fM. Unlike the typical bar-code assay that the bar-code strands should be released and identified on a microarray, this method is more direct. Moreover, because of the selective immune reaction and the dual bar-code mechanism, the resulting method could detect the two targets simultaneously. Multiple analysis in human serum was also performed, suggesting that our strategy was reliable and had a great potential application in early clinical diagnosis.

Object-Location-Aware Hashing for Multi-Label Image Retrieval via Automatic Mask Learning.

PubMed

Huang, Chang-Qin; Yang, Shang-Ming; Pan, Yan; Lai, Han-Jiang

2018-09-01

Learning-based hashing is a leading approach of approximate nearest neighbor search for large-scale image retrieval. In this paper, we develop a deep supervised hashing method for multi-label image retrieval, in which we propose to learn a binary "mask" map that can identify the approximate locations of objects in an image, so that we use this binary "mask" map to obtain length-limited hash codes which mainly focus on an image's objects but ignore the background. The proposed deep architecture consists of four parts: 1) a convolutional sub-network to generate effective image features; 2) a binary "mask" sub-network to identify image objects' approximate locations; 3) a weighted average pooling operation based on the binary "mask" to obtain feature representations and hash codes that pay most attention to foreground objects but ignore the background; and 4) the combination of a triplet ranking loss designed to preserve relative similarities among images and a cross entropy loss defined on image labels. We conduct comprehensive evaluations on four multi-label image data sets. The results indicate that the proposed hashing method achieves superior performance gains over the state-of-the-art supervised or unsupervised hashing baselines.

Paired Comparison Survey Analyses Utilizing Rasch Methodology of the Relative Difficulty and Estimated Work Relative Value Units of CPT® Code 27279.

Minimally invasive sacroiliac joint arthrodesis ("MI SIJ fusion") received a Category I CPT ® code (27279) effective January 1, 2015 and was assigned a work relative value unit ("RVU") of 9.03. The International Society for the Advancement of Spine Surgery ("ISASS") conducted a study consisting of a Rasch analysis of two separate surveys of surgeons to assess the accuracy of the assigned work RVU. A survey was developed and sent to ninety-three ISASS surgeon committee members. Respondents were asked to compare CPT ® 27279 to ten other comparator CPT ® codes reflective of common spine surgeries. The survey presented each comparator CPT ® code with its code descriptor as well as the description of CPT ® 27279 and asked respondents to indicate whether CPT ® 27279 was greater, equal, or less in terms of work effort than the comparator code. A second survey was sent to 557 U.S.-based spine surgeon members of ISASS and 241 spine surgeon members of the Society for Minimally Invasive Spine Surgery ("SMISS"). The design of the second survey mirrored that of the first survey except for the use of a broader set of comparator CPT ® codes (27 vs. 10). Using the work RVUs of the comparator codes, a Rasch analysis was performed to estimate the relative difficulty of CPT ® 27279, after which the work RVU of CPT ® 27279 was estimated by regression analysis. Twenty surgeons responded to the first survey and thirty-four surgeons responded to the second survey. The results of the regression analysis of the first survey indicate a work RVU for CPT ® 27279 of 14.36 and the results of the regression analysis of the second survey indicate a work RVU for CPT ® 27279 of 14.1. The Rasch analysis indicates that the current work RVU assigned to CPT ® 27279 is undervalued at 9.03. Averaging the results of the regression analyses of the two surveys indicates a work RVU for CPT ® 27279 of 14.23.

Health claims in the labelling and marketing of food products:

PubMed Central

Asp, Nils-Georg; Bryngelsson, Susanne

2007-01-01

Since 1990 certain health claims in the labelling and marketing of food products have been allowed in Sweden within the food sector's Code of Practice. The rules were developed in close dialogue with the authorities. The legal basis was a decision by the authorities not to apply the medicinal products’ legislation to “foods normally found on the dinner table” provided the rules defined in the Code were followed. The Code of Practice lists nine well-established diet–health relationships eligible for generic disease risk reduction claims in two steps and general rules regarding nutrient function claims. Since 2001, there has also been the possibility for using “product-specific physiological claims (PFP)”, subject to premarketing evaluation of the scientific dossier supporting the claim. The scientific documentation has been approved for 10 products with PFP, and another 15 products have been found to fulfil the Code's criteria for “low glycaemic index”. In the third edition of the Code, active since 2004, conditions in terms of nutritional composition were set, i.e. “nutrient profiles”, with a general reference to the Swedish National Food Administration's regulation on the use of a particular symbol, i.e. the keyhole symbol. Applying the Swedish Code of practice has provided experience useful in the implementation of the European Regulation on nutrition and health claims made on foods, effective from 2007.

Identification of cellular MMP substrates using quantitative proteomics: isotope-coded affinity tags (ICAT) and isobaric tags for relative and absolute quantification (iTRAQ).

2010-01-01

Identification of protease substrates is essential to understand the functional consequences of normal proteolytic processing and dysregulated proteolysis in disease. Quantitative proteomics and mass spectrometry can be used to identify protease substrates in the cellular context. Here we describe the use of two protein labeling techniques, Isotope-Coded Affinity Tags (ICAT and Isobaric Tags for Relative and Absolute Quantification (iTRAQ), which we have used successfully to identify novel matrix metalloproteinase (MMP) substrates in cell culture systems (1-4). ICAT and iTRAQ can label proteins and protease cleavage products of secreted proteins, protein domains shed from the cell membrane or pericellular matrix of protease-transfected cells that have accumulated in conditioned medium, or cell surface proteins in membrane preparations; isotopically distinct labels are used for control cells. Tryptic digestion and tandem mass spectrometry of the generated fragments enable sequencing of differentially labeled but otherwise identical pooled peptides. The isotopic tag, which is unique for each label, identifies the peptides originating from each sample, for instance, protease-transfected or control cells, and comparison of the peak areas enables relative quantification of the peptide in each sample. Thus proteins present in altered amounts between protease-expressing and null cells are implicated as protease substrates and can be further validated as such.

The implementation of a standardized front-of-pack-labelling (FoPL) scheme would likely be a useful tool for many consumers trying to improve the healthfulness of their diets. Our objective was to examine what the traffic light labelling scheme would look like if implemented in the US. Data were extracted from Label Insight's Open Access branded food database in 2017. Nutrient levels and the proportion of products classified as "Red" (High), "Amber" (Medium) or "Green" (Low) in total fat, saturated fat, total sugar and sodium for food and beverage items were examined. The proportion of products in each category that had each possible combination of traffic light colors, and met the aggregate score for "healthy" was examined. Out of 175,198 products, >50% of all US packaged foods received a "Red" rating for total sugar and sodium. "Confectionery" had the highest mean total sugar (51.9 g/100 g) and "Meat and meat alternatives" the highest mean sodium (781 mg/100 g). The most common traffic light label combination was "Red" for total fat, saturated fat and sodium and "Green" for sugar. Only 30.1% of products were considered "healthy". A wide variety ( n = 80) of traffic light color combinations were observed. A color coded traffic light scheme appears to be an option for implementation across the US packaged food supply to support consumers in making healthier food choices.

Levetiracetam (Keppra) was evaluated in a subset of patients aged >/=65 years (n=78) enrolled in a large (n=1030) open-label, phase IV trial (the KEEPER trial). A 4-week dose adjustment was followed by a 12-week evaluation period. An overall median reduction in partial seizures of 80.1% (n=65) was observed. Overall, 76.9% of patients were >/=50% responders, 56.9% were >/=75% responders, and 40.0% were 100% responders. Levetiracetam was well tolerated, with 42.3% of patients reporting one or more adverse events. A total of 15 patients (19.2%) experienced an adverse event that led to discontinuation. Somnolence (n=13,16.7%) and dizziness (n=7,9.0%) were the most commonly reported adverse events. Despite the limitations of the open-label study design, these data provide information regarding the use of levetiracetam as add-on therapy for the treatment of partial-onset seizures in patients >/=65 years of age, including those requiring concomitant medications.

Why do consumers respond to eco-labels? The case of Korea.

PubMed

Hwang, Jung-Ah; Park, Youkyoung; Kim, Yeonbae

2016-01-01

Although eco-labels were introduced with the intention of encouraging eco-friendly purchasing behavior by consumers, they have had little effect on consumers' purchasing decisions, and therefore a significant gap exists between eco-label awareness and actual purchasing behavior. The aim of this study was to analyze consumer preference, in terms of public and private values, for two types of Korean eco-label that have been administered by the Korean government since 1992. Analyses were based on a structural equation model, employing the theory of reasoned action. Data were collected by survey. The results indicate that although general consumers are highly aware of the publicly valuable information that eco-labels provide, privately valuable information exerts far greater power over their purchasing intentions. Therefore, a supplementary policy that converts public value to private value could promote the purchase of eco-labeled products.

THE TASK FORCE AND MLA STAFF CRAFTED A SURVEY TO DETERMINE: (1) awareness of the MLA code and its provisions, (2) use of the MLA code to resolve professional ethical issues, (3) consultation of other ethical codes or guides, (4) views regarding the relative importance of the eleven MLA code statements, (5) challenges experienced in following any MLA code provisions, and (6) ethical problems not clearly addressed by the code. Over 500 members responded (similar to previous MLA surveys), and while most were aware of the code, over 30% could not remember when they had last read or thought about it, and nearly half had also referred to other codes or guidelines. The large majority thought that: (1) all code statements were equally important, (2) none were particularly difficult or challenging to follow, and (3) the code covered every ethical challenge encountered in their professional work. Comments provided by respondents who disagreed with the majority views suggest that the MLA code could usefully include a supplementary guide with practical advice on how to reason through a number of ethically challenging situations that are typically encountered by health sciences librarians.

Subjective Responses to Emotional Stimuli During Labeling, Reappraisal, and Distraction

2011-01-01

Although multiple neuroimaging studies suggest that affect labeling (i.e., putting feelings into words) can dampen affect-related responses in the amygdala, the consequences of affect labeling have not been examined in other channels of emotional responding. We conducted four studies examining the effect of affect labeling on self-reported emotional experience. In study one, self-reported distress was lower during affect labeling, compared to passive watching, of negative emotional pictures. Studies two and three added reappraisal and distraction conditions, respectively. Affect labeling showed similar effects on self-reported distress as both of these intentional emotion regulation strategies. In each of the first three studies, however, participant predictions about the effects of affect labeling suggest that unlike reappraisal and distraction, people do not believe affect labeling to be an effective emotion regulation strategy. Even after having the experience of affect labels leading to lower distress, participants still predicted that affect labeling would increase distress in the future. Thus, affect labeling is best described as an incidental emotion regulation process. Finally, study four employed positive emotional pictures and here, affect labeling was associated with diminished self-reported pleasure, relative to passive watching. This suggests that affect labeling tends to dampen affective responses in general, rather than specifically alleviating negative affect. PMID:21534661

Victim Responses to Violence: The Effect of Alcohol Context on Crime Labeling.

PubMed

Brennan, Iain

2016-03-01

The labeling of an incident as a crime is an essential precursor to the use of criminal law, but the contextual factors that influence this decision are unknown. One such context that is a frequent setting for violence is the barroom. This study explored how the setting of a violent incident is related to the decision by victims to label it as a crime. It tested the hypothesis that violent incidents that took place in or around a licensed premises were less likely to be regarded as crimes than violence in other settings. The hypothesis was tested using a pooled sample of respondents from successive waves of the British Crime Survey (2002/2003-2010/2011). Logistic regression models controlled for demographic factors, victim behavioral characteristics, and incident-specific factors including the seriousness of the violence. Respondents who were in or around a licensed premises at the time of victimization were less likely to regard that violence as a crime (adjusted odds ratio = 0.48, 95% confidence intervals [CIs] = [0.34, 0.67]) than respondents who were victimized in other locations. Despite a disproportionate amount of violence taking place in barrooms, it appears that the criminal nature of violence in these spaces is discounted by victims. The findings emphasize how context affects victim interpretations of crime and suggest a victim-centered reconceptualization of the "moral holiday" hypothesis of alcohol settings. © The Author(s) 2015.

Infant differential behavioral responding to discrete emotions.

PubMed

Walle, Eric A; Reschke, Peter J; Camras, Linda A; Campos, Joseph J

2017-10-01

Emotional communication regulates the behaviors of social partners. Research on individuals' responding to others' emotions typically compares responses to a single negative emotion compared with responses to a neutral or positive emotion. Furthermore, coding of such responses routinely measure surface level features of the behavior (e.g., approach vs. avoidance) rather than its underlying function (e.g., the goal of the approach or avoidant behavior). This investigation examined infants' responding to others' emotional displays across 5 discrete emotions: joy, sadness, fear, anger, and disgust. Specifically, 16-, 19-, and 24-month-old infants observed an adult communicate a discrete emotion toward a stimulus during a naturalistic interaction. Infants' responses were coded to capture the function of their behaviors (e.g., exploration, prosocial behavior, and security seeking). The results revealed a number of instances indicating that infants use different functional behaviors in response to discrete emotions. Differences in behaviors across emotions were clearest in the 24-month-old infants, though younger infants also demonstrated some differential use of behaviors in response to discrete emotions. This is the first comprehensive study to identify differences in how infants respond with goal-directed behaviors to discrete emotions. Additionally, the inclusion of a function-based coding scheme and interpersonal paradigms may be informative for future emotion research with children and adults. Possible developmental accounts for the observed behaviors and the benefits of coding techniques emphasizing the function of social behavior over their form are discussed.

2010-04-01

The present study examines the receptivity to and potential effects of menu labelling on food choices of low-income and minority individuals - a group often at disproportionate risk for preventable, lifestyle-related health conditions (e.g. obesity, diabetes and CVD). We conducted a cross-sectional survey to examine the knowledge, attitudes and potential response to menu labelling in an urban public health clinic population. United States. A total of 639 clinic patients were recruited in the waiting rooms of six, large public health centres in Los Angeles County (2007-2008). These centres provide services to a largely uninsured or under-insured, low-income, Latino and African-American population. Among those approached and who met eligibility criteria, 88 % completed the survey. Of the 639 respondents, 55 % were overweight or obese based on self-reported heights and weights; 74 % reported visiting a fast food restaurant at least once in the past year, including 22 % at least once a week; 93 % thought that calorie information was 'important'; and 86 % thought that restaurants should be required to post calorie information on their menu boards. In multivariate analyses, respondents who were obese, female, Latino and supportive of calorie postings were more likely than others to report that they would choose food and beverages with lower calories as a result of menu labelling. These findings suggest that clinic patients are receptive to this population-based strategy and that they would be inclined to change their food selections in response to menu labelling.

A Locality-Constrained and Label Embedding Dictionary Learning Algorithm for Image Classification.

PubMed

Zhengming Li; Zhihui Lai; Yong Xu; Jian Yang; Zhang, David

2017-02-01

Locality and label information of training samples play an important role in image classification. However, previous dictionary learning algorithms do not take the locality and label information of atoms into account together in the learning process, and thus their performance is limited. In this paper, a discriminative dictionary learning algorithm, called the locality-constrained and label embedding dictionary learning (LCLE-DL) algorithm, was proposed for image classification. First, the locality information was preserved using the graph Laplacian matrix of the learned dictionary instead of the conventional one derived from the training samples. Then, the label embedding term was constructed using the label information of atoms instead of the classification error term, which contained discriminating information of the learned dictionary. The optimal coding coefficients derived by the locality-based and label-based reconstruction were effective for image classification. Experimental results demonstrated that the LCLE-DL algorithm can achieve better performance than some state-of-the-art algorithms.

Quantitative profiling of O-glycans by electrospray ionization- and matrix-assisted laser desorption ionization-time-of-flight-mass spectrometry after in-gel derivatization with isotope-coded 1-phenyl-3-methyl-5-pyrazolone.

Sić, Siniša; Maier, Norbert M; Rizzi, Andreas M

2016-09-07

The potential and benefits of isotope-coded labeling in the context of MS-based glycan profiling are evaluated focusing on the analysis of O-glycans. For this purpose, a derivatization strategy using d0/d5-1-phenyl-3-methyl-5-pyrazolone (PMP) is employed, allowing O-glycan release and derivatization to be achieved in one single step. The paper demonstrates that this release and derivatization reaction can be carried out also in-gel with only marginal loss in sensitivity compared to in-solution derivatization. Such an effective in-gel reaction allows one to extend this release/labeling method also to glycoprotein/glycoform samples pre-separated by gel-electrophoresis without the need of extracting the proteins/digested peptides from the gel. With highly O-glycosylated proteins (e.g. mucins) LODs in the range of 0.4 μg glycoprotein (100 fmol) loaded onto the electrophoresis gel can be attained, with minor glycosylated proteins (like IgAs, FVII, FIX) the LODs were in the range of 80-100 μg (250 pmol-1.5 nmol) glycoprotein loaded onto the gel. As second aspect, the potential of isotope coded labeling as internal standardization strategy for the reliable determination of quantitative glycan profiles via MALDI-MS is investigated. Towards this goal, a number of established and emerging MALDI matrices were tested for PMP-glycan quantitation, and their performance is compared with that of ESI-based measurements. The crystalline matrix 2,6-dihydroxyacetophenone (DHAP) and the ionic liquid matrix N,N-diisopropyl-ethyl-ammonium 2,4,6-trihydroxyacetophenone (DIEA-THAP) showed potential for MALDI-based quantitation of PMP-labeled O-glycans. We also provide a comprehensive overview on the performance of MS-based glycan quantitation approaches by comparing sensitivity, LOD, accuracy and repeatability data obtained with RP-HPLC-ESI-MS, stand-alone nano-ESI-MS with a spray-nozzle chip, and MALDI-MS. Finally, the suitability of the isotope-coded PMP labeling strategy for O-glycan profiling of biological important proteins is demonstrated by comparative analysis of IgA immunoglobulins and two coagulation factors.

Breast milk substitutes in Hong Kong.

Nelson, E A S; Chan, C W; Yu, C M

2004-07-01

In 1981 the World Health Assembly (WHA) adopted the International Code of Marketing of Breast Milk Substitutes (the Code) to support breastfeeding. Despite improving trends, Hong Kong has low rates of breastfeeding compared to other developed countries. We surveyed companies marketing breast milk substitutes in Hong Kong to determine self-reported adherence to the Code. Companies were informed that individual responses would not be published and seven of nine companies responded to the questionnaire. The majority of respondents promoted infant and follow-on formula in hospitals and provided free supplies of infant formula to hospitals. Follow-on formula and weaning foods were promoted in shops and to the general public and free samples were given to mothers reflecting a belief that, despite WHA resolutions, follow-on formula is not a breast milk substitute. Transnational companies should follow the Code and subsequent WHA resolutions equally in all countries.

Weighting Composite Endpoints in Clinical Trials: Essential Evidence for the Heart Team

Background Coronary revascularization trials often use a composite endpoint of major adverse cardiac and cerebrovascular events (MACCE). The usual practice in analyzing data with a composite endpoint is to assign equal weights to each of the individual MACCE elements. Non-inferiority margins are used to offset effects of presumably less important components, but their magnitudes are subject to bias. This study describes the relative importance of MACCE elements from a patient perspective. Methods A discrete choice experiment was conducted. Survey respondents were presented with a scenario that would make them eligible for the SYNTAX 3-Vessel Disease cohort. Respondents chose among pairs of procedures that differed on the 3-year probability of MACCE, potential for increased longevity, and procedure/recovery time. Conjoint analysis derived relative weights for these attributes. Results In all, 224 respondents completed the survey. The attributes did not have equal weight. Risk of death was most important (relative weight 0.23), followed by stroke (.18), potential increased longevity and recovery time (each 0.17), MI (0.14) and risk of repeat revascularization (0.11). Applying these weights to the SYNTAX 3-year endpoints resulted in a persistent, but decreased margin of difference in MACCE favoring CABG compared to PCI. When labeled only as “Procedure A” and “B,” 87% of respondents chose CABG over PCI. When procedures were labeled as “Coronary Stent” and “Coronary Bypass Surgery,” only 73% chose CABG. Procedural preference varied with demographics, gender and familiarity with the procedures. Conclusions MACCE elements do not carry equal weight in a composite endpoint, from a patient perspective. Using a weighted composite endpoint increases the validity of statistical analyses and trial conclusions. Patients are subject to bias by labels when considering coronary revascularization.

Glycan reductive isotope labeling (GRIL) using (12)C6-/(13)C6-aniline as labeling reagent is reported with the aim of quantitative N-glycan fingerprinting. Porous graphitized carbon (PGC) as stationary phase in capillary scale HPLC coupled to electrospray mass spectrometry with time of flight analyzer was applied for the determination of labeled N-glycans released from glycoproteins. The main benefit of using stable isotope-coding in the context of comparative glycomics lies in the improved accuracy and precision of the quantitative analysis in combined samples and in the potential of correcting for structure-dependent incomplete enzymatic release of oligosaccharides when comparing identical target proteins. The method was validated with respect to mobile phase parameters, reproducibility, accuracy, linearity and limit of detection/quantification (LOD/LOQ) using test glycoproteins. It is shown that the developed method is capable of determining relative amounts of N-glycans (including isomers) comparing two samples in one single HPLC-MS run. The analytical potential and usefulness of GRIL in combination with PGC-ESI-TOF-MS is demonstrated comparing glycosylation in human monoclonal antibodies produced in Chinese hamster ovary cells (CHO) and hybridoma cell lines.

Many diseases and disorders are characterized by quantitative and/or qualitative changes in complex carbohydrates. Mass spectrometry methods show promise in monitoring and detecting these important biological changes. Here we report a new glycomics method, termed glycan reductive isotope labeling (GRIL), where free glycans are derivatized by reductive amination with the differentially coded stable isotope tags [(12)C(6)]aniline and [(13)C(6)]aniline. These dual-labeled aniline-tagged glycans can be recovered by reverse-phase chromatography and can be quantified based on ultraviolet (UV) absorbance and relative ion abundances. Unlike previously reported isotopically coded reagents for glycans, GRIL does not contain deuterium, which can be chromatographically resolved. Our method shows no chromatographic resolution of differentially labeled glycans. Mixtures of differentially tagged glycans can be directly compared and quantified using mass spectrometric techniques. We demonstrate the use of GRIL to determine relative differences in glycan amount and composition. We analyze free glycans and glycans enzymatically or chemically released from a variety of standard glycoproteins, as well as human and mouse serum glycoproteins, using this method. This technique allows linear relative quantitation of glycans over a 10-fold concentration range and can accurately quantify sub-picomole levels of released glycans, providing a needed advancement in the field of glycomics.

We assessed whether a 2-phase labeling and choice architecture intervention would increase sales of healthy food and beverages in a large hospital cafeteria. Phase 1 was a 3-month color-coded labeling intervention (red = unhealthy, yellow = less healthy, green = healthy). Phase 2 added a 3-month choice architecture intervention that increased the visibility and convenience of some green items. We compared relative changes in 3-month sales from baseline to phase 1 and from phase 1 to phase 2. At baseline (977,793 items, including 199,513 beverages), 24.9% of sales were red and 42.2% were green. Sales of red items decreased in both phases (P < .001), and green items increased in phase 1 (P < .001). The largest changes occurred among beverages. Red beverages decreased 16.5% during phase 1 (P < .001) and further decreased 11.4% in phase 2 (P < .001). Green beverages increased 9.6% in phase 1 (P < .001) and further increased 4.0% in phase 2 (P < .001). Bottled water increased 25.8% during phase 2 (P < .001) but did not increase at 2 on-site comparison cafeterias (P < .001). A color-coded labeling intervention improved sales of healthy items and was enhanced by a choice architecture intervention.

2012-01-01

Background Effective strategies are needed to address obesity, particularly among minority and low-income individuals. Purpose To test whether a two-phase point-of-purchase intervention improved food choices across racial, socioeconomic (job type) groups. Design A 9-month longitudinal study from 2009 to 2010 assessing person-level changes in purchases of healthy and unhealthy foods following sequentially introduced interventions. Data were analyzed in 2011. Setting/participants Participants were 4642 employees of a large hospital in Boston MA who were regular cafeteria patrons. Interventions The first intervention was a traffic light–style color-coded labeling system encouraging patrons to purchase healthy items (labeled green) and avoid unhealthy items (labeled red). The second intervention manipulated “choice architecture” by physically rearranging certain cafeteria items, making green-labeled items more accessible, red-labeled items less accessible. Main outcome measures Proportion of green- (or red-) labeled items purchased by an employee. Subanalyses tracked beverage purchases, including calories and price per beverage. Results Employees self-identified as white (73%), black (10%), Latino (7%), and Asian (10%). Compared to white employees, Latino and black employees purchased a higher proportion of red items at baseline (18%, 28%, and 33%, respectively, p<0.001) and a lower proportion of green (48%, 38%, and 33%, p<0.001). Labeling decreased all employees’ red item purchases (−11.2% [95% CI= −13.6%, −8.9%]) and increased green purchases (6.6% [95% CI=5.2%, 7.9%]). Red beverage purchases decreased most (−23.8% [95% CI= −28.1%, −19.6%]). The choice architecture intervention further decreased red purchases after the labeling. Intervention effects were similar across all race/ethnicity and job types (p>0.05 for interaction between race or job type and intervention). Mean calories per beverage decreased similarly over the study period for all racial groups and job types, with no increase in per-beverage spending. Conclusions Despite baseline differences in healthy food purchases, a simple color-coded labeling and choice architecture intervention improved food and beverage choices among employees from all racial and socioeconomic backgrounds.

Graham, Dan J; Lucas-Thompson, Rachel G; Mueller, Megan P; Jaeb, Melanie; Harnack, Lisa

2017-04-01

The present study investigated whether parent/child pairs would select more healthful foods when: (i) products were labelled with front-of-package (FOP) nutrition labels relative to packages without labels; (ii) products were labelled with colour-coded Multiple Traffic Light (MTL) FOP labels relative to monochromatic Facts up Front (FuF) FOP labels; and (iii) FOP labels were explained via in-aisle signage v. unexplained. Participants were randomly assigned to one of five conditions: (i) FuF labels with in-aisle signs explaining the labels; (ii) FuF labels, no signage; (iii) MTL labels with in-aisle signage; (iv) MTL labels, no signage; (v) control group, no labels/signage. Saturated fat, sodium, sugar and energy (calorie) content were compared across conditions. The study took place in a laboratory grocery aisle. Parent/child pairs (n 153) completed the study. Results did not support the hypothesis that MTL labels would lead to more healthful choices than FuF labels. The presence of FOP labels did little to improve the healthfulness of selected foods, with few exceptions (participants with v. without access to FOP labels selected lower-calorie cereals, participants with access to both FOP labels and in-aisle explanatory signage selected products with less saturated fat v. participants without explanatory signage). Neither MTL nor FuF FOP labels led to food choices with significantly lower saturated fat, sodium or sugar. In-aisle signs explaining the FOP labels were somewhat helpful to consumers in making more healthful dietary decisions. New FOP labelling programmes could benefit from campaigns to increase consumer awareness and understanding of the labels.

Keys and seats: Spatial response coding underlying the joint spatial compatibility effect.

PubMed

Dittrich, Kerstin; Dolk, Thomas; Rothe-Wulf, Annelie; Klauer, Karl Christoph; Prinz, Wolfgang

2013-11-01

Spatial compatibility effects (SCEs) are typically observed when participants have to execute spatially defined responses to nonspatial stimulus features (e.g., the color red or green) that randomly appear to the left and the right. Whereas a spatial correspondence of stimulus and response features facilitates response execution, a noncorrespondence impairs task performance. Interestingly, the SCE is drastically reduced when a single participant responds to one stimulus feature (e.g., green) by operating only one response key (individual go/no-go task), whereas a full-blown SCE is observed when the task is distributed between two participants (joint go/no-go task). This joint SCE (a.k.a. the social Simon effect) has previously been explained by action/task co-representation, whereas alternative accounts ascribe joint SCEs to spatial components inherent in joint go/no-go tasks that allow participants to code their responses spatially. Although increasing evidence supports the idea that spatial rather than social aspects are responsible for joint SCEs emerging, it is still unclear to which component(s) the spatial coding refers to: the spatial orientation of response keys, the spatial orientation of responding agents, or both. By varying the spatial orientation of the responding agents (Exp. 1) and of the response keys (Exp. 2), independent of the spatial orientation of the stimuli, in the present study we found joint SCEs only when both the seating and the response key alignment matched the stimulus alignment. These results provide evidence that spatial response coding refers not only to the response key arrangement, but also to the-often neglected-spatial orientation of the responding agents.

Calorie-labelling in catering outlets: acceptability and impacts on food sales.

Obesity is the biggest challenge facing preventive medicine. Calorie-labelling has been suggested as a way of changing the architecture of an 'obesogenic' environment without limiting consumer choice. This study examined the effect of calorie-labelling on sales of food items at catering outlets on a city-centre university campus. Sales data were collected for two consecutive months in 2013 on three UK university sites (two with calorie-labelling during second month, one control) and analysed with chi-square 'Goodness-of-Fit' tests. A questionnaire seeking consumers' views and use of the calorie-labelling was administered and analysed at group-level with chi-square tests. In intervention vs control sites, total sales of all labelled items fell significantly (-17% vs -2%, p<0.001) for the month with calorie-labelling. Calorie-labelling was associated with substantially reduced sales of high-calorie labelled items, without any compensatory changes in unlabelled alternative items. Among 1166 student- and 646 staff-respondents, 56% reported using the calorie-labels, 97% of them to make lower-calorie choices. More females (63%) than males (40%) reported being influenced by calorie-labels when choosing foods (p=0.01). This study provides evidence, beyond that from single-meal exposures, for the acceptability of meal calorie-labelling and its potential as an effective low-cost anti-obesity measure.

Identification of Gustatory–Olfactory Flavor Mixtures: Effects of Linguistic Labeling

PubMed Central

2013-01-01

Two experiments, using different ranges and numbers of stimuli, examined how linguistic labels affect the identification of flavor mixtures containing different proportions of sucrose (gustatory flavorant) and citral (olfactory flavorant). Both experiments asked subjects to identify each stimulus as having either “mostly sugar” or “mostly citrus.” In one condition, no labels preceded the flavor stimuli. In another condition, each flavor stimulus followed a label, either SUGAR or CITRUS, which, the subjects were informed, usually though not always named the stronger flavor component; that is, the labels were probabilistically valid. The results of both experiments showed that the labels systematically modified the identification responses: Subjects responded “sugar” or “citrus” more often when the flavor stimulus followed the corresponding label, SUGAR or CITRUS. But the labels hardly affected overall accuracy of identification. Accuracy was possibly limited, however, by both the confusability of the flavor stimuli per se and the way that confusability could limit the opportunity to discern the probabilistic associations between labels and individual flavor stimuli. We describe the results in terms of a decision-theoretic model, in which labels induce shifts in response criteria governing the identification responses, or possibly effect changes in the sensory representations of the flavorants themselves.

Bar code, good for industry and trade--how does it benefit the dentist?

Oehlmann, H

2001-10-01

Every dentist who attentively follows the change in product labelling can easily see that the HIBC bar code is on the increase. In fact, according to information from FIDE/VDDI and ADE/BVD, the dental industry and trade are firmly resolved to apply the HIBC bar code to all products used internationally in dental practices. Why? Indeed, at first it looks like extra expense to additionally print a bar code on the packages. Good reasons can only lie in advantages which manufacturers and the trade expect from the HIBC bar code, Indications in dental technician circles are that the HIBC bar code is coming. If there are advantages, what are these, and can the dentist also profit from them? What does HIBC bar code mean and what items of interest does it include? What does bar code cost and does only one code exist? This is explained briefly, concentrating on the benefits bar code can bring for different users.

The current study examined whether and which specific contents of patients' memory for cognitive therapy (CT) were associated with treatment adherence and outcome. Data were drawn from a pilot RCT of forty-eight depressed adults, who received either CT plus Memory Support Intervention (CT + Memory Support) or CT-as-usual. Patients' memory for treatment was measured using the Patient Recall Task and responses were coded into cognitive behavioral therapy (CBT) codes, such as CBT Model and Cognitive Restructuring, and non-CBT codes, such as individual coping strategies and no code. Treatment adherence was measured using therapist and patient ratings during treatment. Depression outcomes included treatment response, remission, and recurrence. Total number of CBT codes recalled was not significantly different comparing CT + Memory Support to CT-as-usual. Total CBT codes recalled were positively associated with adherence, while non-CBT codes recalled were negatively associated with adherence. Treatment responders (vs. non-responders) exhibited a significant increase in their recall of Cognitive Restructuring from session 7 to posttreatment. Greater recall of Cognitive Restructuring was marginally significantly associated with remission. Greater total number of CBT codes recalled (particularly CBT Model) was associated with non-recurrence of depression. Results highlight the important relationships between patients' memory for treatment and treatment adherence and outcome. Copyright © 2017 Elsevier Ltd. All rights reserved.

Diarrhea-predominant irritable bowel syndrome (IBS-D) impairs patient quality of life (QOL). Rifaximin is an oral, nonsystemic antibiotic indicated for IBS-D. The objective of this secondary analysis was to evaluate rifaximin retreatment on IBS-related QOL in patients with IBS-D. Patients received open-label rifaximin 550 mg three times daily for 2 weeks. Clinical responders [simultaneously meeting weekly response criteria for abdominal pain (⩾30% improvement from baseline in mean weekly pain score) and stool consistency (⩾50% decrease from baseline in number of days/week with Bristol Stool Scale (BSS) type 6 or 7 stools) during ⩾2 of first 4 weeks posttreatment] who relapsed during an up to 18-week treatment-free observation phase were randomly assigned to receive two 2-week courses of double-blind rifaximin or placebo, separated by 10 weeks. A validated 34-item IBS-QOL questionnaire examined patient responses in 8 domains. The 2579 patients receiving open-label rifaximin experienced a mean improvement from baseline in IBS-QOL overall score of 54.9%. Responders to open-label rifaximin ( n = 1074 of 2438 evaluable; 44.1%) had significantly greater improvement from baseline in IBS-QOL overall and all eight subdomain scores, including dysphoria, food avoidance, interference with activity, body image, and sexual function versus nonresponders at 4 weeks posttreatment ( n = 1364; p < 0.001 for all comparisons). A significantly greater percentage of responders to open-label rifaximin achieved the minimally clinically important difference (MCID; ⩾14-point improvement from baseline) in the overall IBS-QOL score versus nonresponders [ n = 561 (52.2%) versus n = 287 (21.0%); p < 0.0001]. Among 636 patients with IBS-D relapse, the MCID in the overall IBS-QOL score was achieved by a significantly greater percentage of patients receiving double-blind rifaximin versus placebo (38.6% versus 29.6%, respectively; p = 0.009). Open-label and blinded retreatment with a short course (2 weeks) of rifaximin improved IBS-QOL in patients with IBS-D [ClinicalTrials.gov identifier: NCT01543178].

Educational Labeling System for Atmospheres (ELSA): Python Tool Development for Archiving Under the PDS4 Standard

The Research and Analysis programs within NASA’s Planetary Science Division now require archiving of resultant data with the Planetary Data System (PDS) or an equivalent archive. The PDS Atmospheres Node is developing an online environment for assisting data providers with this task. The Educational Labeling System for Atmospheres (ELSA) is being designed with Django/Python coding to provide an easier environment for facilitating not only communication with the PDS node, but also streamlining the process of learning, developing, submitting, and reviewing archive bundles under the new PDS4 archiving standard. Under the PDS4 standard, data are archived in bundles, collections, and basic products that form an organizational hierarchy of interconnected labels that describe the data and relationships between the data and its documentation. PDS4 labels are implemented using Extensible Markup Language (XML), which is an international standard for managing metadata. Potential data providers entering the ELSA environment can learn more about PDS4, plan and develop label templates, and build their archive bundles. ELSA provides an interface to tailor label templates aiding in the creation of required internal Logical Identifiers (URN - Uniform Resource Names) and Context References (missions, instruments, targets, facilities, etc.). The underlying structure of ELSA uses Django/Python code that make maintaining and updating the interface easy to do for our undergraduate/graduate students. The ELSA environment will soon provide an interface for using the tailored templates in a pipeline to produce entire collections of labeled products, essentially building the user’s archive bundle. Once the pieces of the archive bundle are assembled, ELSA provides options for queuing the completed bundle for peer review. The peer review process has also been streamlined for online access and tracking to help make the archiving process with PDS as transparent as possible. We discuss the current status of ELSA and provide examples of its implementation.

To provide the first systematic analysis of a national (Wales) sample of free-text comments from patients with cancer, to determine emerging themes and insights regarding experiences of cancer care in Wales. Thematic analysis of free-text data from a population-based survey. Adult patients with a confirmed cancer diagnosis treated within a 3-month period during 2012 in the 7 health boards and 1 trust providing cancer care in Wales. Free-text categorised by theme, coded as positive or negative, with ratios. Overarching themes are identified incorporating comment categories. 4672 respondents (of n=7352 survey respondents) provided free-text comments. Data were coded using a multistage approach: (1) coding of comments into general categories (eg, nursing, surgery, etc), (2) coding of subcategories within main categories (eg, nursing care, nursing communication, etc), (3) cross-sectional analysis to identify themes cutting across categories, (4) mapping of categories/subcategories to corresponding closed questions in the Wales Cancer Patient Experience Survey (WCPES) data for comparison. Most free-text respondents (82%, n 3818) provided positive comments about their cancer care, with 49% (n=2313) giving a negative comment (ratio 0.6:1, negative-to-positive). 3172 respondents (67.9% of free-text respondents) provided a comment mapping to 1 of 4 overarching themes: communication (n=1673, 35.8% free-text respondents, a ratio of 1.0:1); waiting during the treatment and/or post-treatment phase (n=923, 19.8%, ratio 1.5:1); staffing and resource levels (n=671, 14.4% ratio 5.3:1); speed and quality of diagnostic care (n=374, 8.0%, ratio 1.5:1). Within these areas, constituent subthemes are discussed. This study presents specific areas of concern for patients with cancer, and reveals a number of themes present across the cancer journey. While the majority of comments were positive, analysis reveals concerns shared by significant numbers of respondents. Timely communication can help to manage these anxieties, even where delays or difficulties in treatment may be encountered. Published by the BMJ Publishing Group Limited.

Obstacles to nutrition labeling in restaurants.

PubMed

Almanza, B A; Nelson, D; Chai, S

1997-02-01

This study determined the major obstacles that foodservices face regarding nutrition labeling. Survey questionnaire was conducted in May 1994. In addition to demographic questions, the directors were asked questions addressing willingness, current practices, and perceived obstacles related to nutrition labeling. Sixty-eight research and development directors of the largest foodservice corporations as shown in Restaurants & Institutions magazine's list of the top 400 largest foodservices (July 1993). P tests were used to determine significance within a group for the number of foodservices that were currently using nutrition labeling, perceived impact of nutrition labeling on sales, and perceived responsibility to add nutrition labels. Regression analysis was used to determine the importance of factors on willingness to label. Response rate was 45.3%. Most companies were neutral about their willingness to use nutrition labeling. Two thirds of the respondents were not currently using nutrition labels. Only one third thought that it was the foodservice's responsibility to provide such information. Several companies perceived that nutrition labeling would have a potentially negative effect on annual sales volume. Major obstacles were identified as menu or personnel related, rather than cost related. Menu-related obstacles included too many menu variations, limited space on the menu for labeling, and loss of flexibility in changing the menu. Personnel-related obstacles included difficulty in training employees to implement nutrition labeling, and not enough time for foodservice personnel to implement nutrition labeling. Numerous opportunities will be created for dietetics professionals in helping foodservices overcome these menu- or personnel-related obstacles.

Objectives. We assessed whether a 2-phase labeling and choice architecture intervention would increase sales of healthy food and beverages in a large hospital cafeteria. Methods. Phase 1 was a 3-month color-coded labeling intervention (red = unhealthy, yellow = less healthy, green = healthy). Phase 2 added a 3-month choice architecture intervention that increased the visibility and convenience of some green items. We compared relative changes in 3-month sales from baseline to phase 1 and from phase 1 to phase 2. Results. At baseline (977 793 items, including 199 513 beverages), 24.9% of sales were red and 42.2% were green. Sales of red items decreased in both phases (P < .001), and green items increased in phase 1 (P < .001). The largest changes occurred among beverages. Red beverages decreased 16.5% during phase 1 (P < .001) and further decreased 11.4% in phase 2 (P < .001). Green beverages increased 9.6% in phase 1 (P < .001) and further increased 4.0% in phase 2 (P < .001). Bottled water increased 25.8% during phase 2 (P < .001) but did not increase at 2 on-site comparison cafeterias (P < .001). Conclusions. A color-coded labeling intervention improved sales of healthy items and was enhanced by a choice architecture intervention. PMID:22390518

Spatially tuned resonant nano-clusters allow high local field enhancement when exited by electromagnetic radiation. A number of phenomena had been described and subsequently applied to novel nano- and bionano-devices. Decisive for these types of devices and sensors is the precise nanometric assembly, coupling the local field surrounding a cluster to allow resonance with other elements interacting with this field. In particular, the distance cluster-mirror or cluster-fluorophore gives rise to a variety of enhancement phenomena. High throughput transducers using metal cluster resonance technology are based on surface-enhancement of metal cluster light absorption (SEA). The optical property for the analytical application of metal cluster films is the so-called anomalous absorption. At a well defined nanometric distance of a cluster to a mirror the reflected electromagnetic field has the same phase at the position of the absorbing cluster as the incident fields. This feedback mechanism strongly enhances the effective cluster absorption coefficient. The system is characterised by a narrow reflection minimum. Based on this SEA-phenomenon (licensed to and further developed and optimized by NovemberAG, Germany Erlangen) a number of commercial products have been constructed. Brandsealing(R) uses the patented SEA cluster technology to produce optical codings. Cluster SEA thin film systems show a characteristic color-flip effect and are extremely mechanically and thermally robust. This is the basis for its application as an unique security feature. The specific spectroscopic properties as e.g. narrow band multi-resonance of the cluster layers allow the authentication of the optical code which can be easily achieved with a mobile hand-held reader developed by november AG and Siemens AG. Thus, these features are machine-readable which makes them superior to comparable technologies. Cluster labels are available in two formats: as a label for tamper-proof product packaging, and as a direct label, where label and logo are permanently applied directly and unremovable to the product surface. Together with Infineon Technologies and HUECK FOLIEN, the SEA technology is currently developed as a direct label for e.g. SmartCards.

Experience with the use of the Codonics Safe Label System(™) to improve labelling compliance of anaesthesia drugs.

The Codonics Safe Labeling System(™) (http://www.codonics.com/Products/SLS/flash/) is a piece of equipment that is able to barcode scan medications, read aloud the medication and the concentration and print a label of the appropriate concentration in the appropriate colour code. We decided to test this system in our facility to identify risks, benefits and usability. Our project comprised a baseline survey (25 anaesthesia cases during which 212 syringes were prepared from 223 drugs), an observational study (47 cases with 330 syringes prepared) and a user acceptability survey. The baseline compliance with all labelling requirements was 58%. In the observational study the compliance using the Codonics system was 98.6% versus 63.8% with conventional labelling. In the user acceptability survey the majority agreed the Codonics machine was easy to use, more legible and adhered with better security than the conventional preprinted label. However, most were neutral when asked about the likelihood of flexibility and customisation and were dissatisfied with the increased workload. Our findings suggest that the Codonics labelling machine is user-friendly and it improved syringe labelling compliance in our study. However, staff need to be willing to follow proper labelling workflow rather than batch label during preparation. Future syringe labelling equipment developers need to concentrate on user interface issues to reduce human factor and workflow problems. Support logistics are also an important consideration prior to implementation of any new labelling system.

To measure compliance with the International Code of Marketing of Breast-milk Substitutes ('the Code') in Indonesia. The study was a cross-sectional survey using the Interagency Group on Breastfeeding Monitoring protocol. Public and private health facilities in six provinces on Java island in Indonesia. A total of 874 women (382 pregnant women and 492 breast-feeding mothers of infants below 6 months) and seventy-seven health workers were recruited from eighteen participating health facilities. The study also analysed a total of forty-four labels of breast-milk substitute products, twenty-seven television commercials for growing-up milk (for children >12 months) of nine brands and thirty-four print advertisements of fourteen brands. The study found that 20 % of the women had received advice and information on the use of breast-milk substitutes and 72 % had seen promotional materials for breast-milk substitutes. About 15 % reported receiving free samples and 16 % received gifts. Nearly a quarter of the health workers confirmed receiving visits from representatives of breast-milk substitute companies. Two health workers reported having received gifts from the companies. The most common labelling violations found were statements or visuals that discouraged breast-feeding and the absence of mention about the consideration of local climate in the expiration date. Violations of the Code by health workers, breast-milk substitute companies and their representatives were found in all provinces studied. A regular monitoring system should be in place to ensure improved compliance with and enforcement of the Code.

Body category-selective regions of the primate temporal cortex respond to images of bodies, but it is unclear which fragments of such images drive single neurons' responses in these regions. Here we applied the Bubbles technique to the responses of single macaque middle superior temporal sulcus (midSTS) body patch neurons to reveal the image fragments the neurons respond to. We found that local image fragments such as extremities (limbs), curved boundaries, and parts of the torso drove the large majority of neurons. Bubbles revealed the whole body in only a few neurons. Neurons coded the features in a manner that was tolerant to translation and scale changes. Most image fragments were excitatory but for a few neurons both inhibitory and excitatory fragments (opponent coding) were present in the same image. The fragments we reveal here in the body patch with Bubbles differ from those suggested in previous studies of face-selective neurons in face patches. Together, our data indicate that the majority of body patch neurons respond to local image fragments that occur frequently, but not exclusively, in bodies, with a coding that is tolerant to translation and scale. Overall, the data suggest that the body category selectivity of the midSTS body patch depends more on the feature statistics of bodies (e.g., extensions occur more frequently in bodies) than on semantics (bodies as an abstract category).

"Miscommunication" and Undergraduate Women's Conceptualizations of Sexual Assault: A Qualitative Analysis.

Dardis, Christina M; Kraft, Kathryn M; Gidycz, Christine A

2017-08-01

Approximately 60% of legally defined rape victims do not label their experiences as "rape," most of whom label the experience as "a serious miscommunication." However, little research has examined why women choose this label. Labeling rape as a miscommunication could be problematic if chosen due to stereotypical conceptions that one's experience is not "real" rape. The present study used a mixed-methodological approach to understand why women might refer to rape as a "miscommunication," and how their reasons for labeling might differ from those who label their experiences and those who are nonlabeled (i.e., unequivocally state that they were "not victimized"). Participants included 123 undergraduate women who experienced rape. Participants responded to how they labeled rape and answered questions regarding assault characteristics, disclosure, reporting, and self- and perpetrator blame. Chi-square analyses assessed labeling group differences. Responses to an open-ended question about factors contributing to their labeling decision were content analyzed. Whereas miscommunication-labeled and nonlabeled victims reported similar assault characteristics in the quantitative analyses, qualitative content analyses revealed varying reasons for labeling rape as miscommunication, not victimization, and rape. Over three quarters of miscommunication-labeled victims reported that one or more of the following factors influenced their labeling: victim and perpetrator substance use, sexual activity prior to the rape, and perceptions that one did not express nonconsent strongly enough and that the perpetrator "did not realize" their lack of desire. Whereas miscommunication-labeled and nonlabeled victims reported similar assault characteristics, the extent to which those assault characteristics affected their labeling differed. Those who labeled their experiences as miscommunication gave reasons for their label that centered on factors which reflect inconsistencies between their experiences and "stereotypical rape." Misperceptions of rape can be addressed via prevention programming and clinical work.

Objectives We analysed near-miss and injury events reported to the National Fire Fighter Near-Miss Reporting System (NFFNMRS) to investigate the workplace hazards and safety concerns of Emergency Medical Services (EMS) responders in the USA. Methods We reviewed 769 ‘non-fire emergency event’ reports from the NFFNMRS using a mixed methods approach. We identified 185 emergency medical calls and analysed their narrative text fields. We assigned Mechanism of Near-Miss/Injury and Nature of Injury codes and then tabulated frequencies (quantitative). We coded major themes regarding work hazards and safety concerns reported by the EMS responders (qualitative). Results Of the 185 emergency medical calls, the most commonly identified Mechanisms of Near-Miss/Injury to EMS responders was Assaults, followed by Struck-by Motor Vehicle, and Motor Vehicle Collision. The most commonly identified weapon used in an assault was a firearm. We identified 5 major domains of workplace hazards and safety concerns: Assaults by Patients, Risks from Motor Vehicles, Personal Protective Equipment, Relationships between Emergency Responders, and Policies, Procedures and Practices. Conclusions Narrative text from the NFFNMRS is a rich source of data that can be analysed quantitatively and qualitatively to provide insight into near-misses and injuries sustained by EMS responders. Near-miss reporting systems are critical components for occupational hazard surveillance. PMID:26068510

The effects of echolalia on acquisition and generalization of receptive labeling in autistic children.

Charlop, M H

1983-01-01

This investigation, consisting of two experiments, was designed to assess the effects of autistic immediate echolalia on acquisition and generalization of receptive labeling tasks. Experiment 1 addressed whether autistic children could use their echolalia to facilitate acquisition. The results indicated that incorporating echolalia (echo of the requested object's label) into the task before manual response (handing the requested object to the experimenter) facilitated receptive labeling. Experiment 2 was designed to determine the effects of incorporating echolalia into task response on acquisition and subsequent generalization. These results indicated that echolalia facilitated generalization for echolalic autistic children but not for functionally mute autistic children. The results of the experiments are discussed in terms of stimulus control. Additionally, it is proposed that perhaps in certain cases, echolalia should not be eliminated, but used to advantage in receptive responding. PMID:6833164

The spatial representation of power in children.

2017-11-01

Previous evidence demonstrates that power is mentally represented as vertical space by adults. However, little is known about how power is mentally represented in children. The current research examines such representations. The influence of vertical information (motor cues) was tested in both an explicit power evaluation task (judge whether labels refer to powerless or powerful groups) and an incidental task (judge whether labels refer to people or animals). The results showed that when power was explicitly evaluated, vertical motor responses interfered with responding in children and adults, i.e., they responded to words representing powerful groups faster with the up than the down cursor key (and vice versa for powerless groups). However, this interference effect disappeared in the incidental task in children. The findings suggest that children have developed a spatial representation of power before they have been taught power-space associations formally, but that they do not judge power spontaneously.

Enhanced Labeling Techniques to Study the Cytoskeleton During Root Growth and Gravitropism

NASA Technical Reports Server (NTRS)

Blancaflor, Elison B.

2005-01-01

Gravity effects the growth and development of all living organisms. One of the most obvious manifestations of gravity's effects on biological systems lies in the ability of plants to direct their growth along a path that is dictated by the gravity vector (called gravitropism). When positioned horizontally, in florescence stems and hypocotyls in dicots, and pulvini in monocots, respond by bending upward whereas roots typically bend downward. Gravitropism allows plants to readjust their growth to maximize light absorption for photosynthesis and to more efficiently acquire water and nutrients form the soil. Despite its significance for plant survival, there are still major gaps in understanding the cellular and molecular processes by which plants respond to gravity. The major aim of this proposal was to develop improved fluorescence labeling techniques to aid in understanding how the cytoskeleton modulated plant responses to gravity.

While atomoxetine is an established treatment for attention-deficit/hyperactivity disorder in children, few studies have examined its efficacy for adults. Open-label trial of atomoxetine in 20 individuals with ADHD, aged 19-47 years, for 10 weeks, and a total of one year for responders. Ten patients met primary efficacy criteria at 10 weeks. Only one patient completed the whole study. Six patients discontinued before 10 weeks and thirteen at 10 weeks or later, mainly because of side-effects (aggression, depressed mood, raised liver enzymes, thyroid hormones, diastolic blood pressure), decreasing efficacy or non-compliance. Fifty percent responded to treatment, but only one patient (5%) felt sufficient improvement to continue for one year. Dosage may have been too low, and baseline impairment too high, for atomoxetine to have sufficient effect on ADHD symptoms in our group of adults. The majority had few side-effects, but several terminated treatment because of adverse effects.

Long-term safety and efficacy of dalfampridine for walking impairment in patients with multiple sclerosis: Results of open-label extensions of two Phase 3 clinical trials

Goodman, Andrew D; Bethoux, Francois; Brown, Theodore R; Schapiro, Randall T; Cohen, Ron; Marinucci, Lawrence N; Henney, Herbert R

2015-01-01

Background: In Phase 3 double-blind trials (MS-F203 and MS-F204), dalfampridine extended release tablets 10 mg twice daily (dalfampridine-ER; prolonged-release fampridine in Europe; fampridine modified or sustained release elsewhere) improved walking speed relative to placebo in patients with multiple sclerosis (MS). Objectives: Evaluation of long-term safety and efficacy of dalfampridine-ER in open-label extensions (MS-F203EXT, MS-F204EXT). Methods: Patients received dalfampridine-ER 10 mg twice daily; and had Timed 25-Foot Walk (T25FW) assessments at 2, 14 and 26 weeks, and then every 6 months. Subjects were categorized as dalfampridine-ER responders or non-responders, based on their treatment response in the double-blind parent trials that assessed T25FW. Results: We had 269 patients enter MS-F203EXT and 154 patients complete it; for a maximum exposure of 5 years. We had 214 patients enter MS-F204EXT and 146 complete it; for a maximum exposure of 3.3 years. No new safety signals emerged and dalfampridine-ER tolerability was consistent with the double-blind phase. Improvements in walking speed were lost after dalfampridine-ER was discontinued in the parent trial, but returned by the 2-week assessment after re-initiation of the drug. Throughout the extensions, mean improvement in walking speed declined, but remained improved, among the double-blind responders as compared with non-responders. Conclusions: The dalfamipridine-ER safety profile was consistent with the parent trials. Although walking speed decreased over time, dalfampridine-ER responders continued to show improved walking speed, which was sustained compared with non-responders. PMID:25583832

Developing an ethical code for engineers: the discursive approach.

PubMed

Lozano, J Félix

2006-04-01

From the Hippocratic Oath on, deontological codes and other professional self-regulation mechanisms have been used to legitimize and identify professional groups. New technological challenges and, above all, changes in the socioeconomic environment require adaptable codes which can respond to new demands. We assume that ethical codes for professionals should not simply focus on regulative functions, but must also consider ideological and educative functions. Any adaptations should take into account both contents (values, norms and recommendations) and the drafting process itself. In this article we propose a process for developing a professional ethical code for an official professional association (Colegio Oficial de Ingenieros Industriales de Valencia (COIIV) starting from the philosophical assumptions of discursive ethics but adapting them to critical hermeneutics. Our proposal is based on the Integrity Approach rather than the Compliance Approach. A process aiming to achieve an effective ethical document that fulfils regulative and ideological functions requires a participative, dialogical and reflexive methodology. This process must respond to moral exigencies and demands for efficiency and professional effectiveness. In addition to the methodological proposal we present our experience of producing an ethical code for the industrial engineers' association in Valencia (Spain) where this methodology was applied, and we evaluate the detected problems and future potential.

Green disease in optical coherence tomography diagnosis of glaucoma.

Sayed, Mohamed S; Margolis, Michael; Lee, Richard K

2017-03-01

Optical coherence tomography (OCT) has become an integral component of modern glaucoma practice. Utilizing color codes, OCT analysis has rendered glaucoma diagnosis and follow-up simpler and faster for the busy clinician. However, green labeling of OCT parameters suggesting normal values may confer a false sense of security, potentially leading to missed diagnoses of glaucoma and/or glaucoma progression. Conditions in which OCT color coding may be falsely negative (i.e., green disease) are identified. Early glaucoma in which retinal nerve fiber layer (RNFL) thickness and optic disc parameters, albeit labeled green, are asymmetric in both eyes may result in glaucoma being undetected. Progressively decreasing RNFL thickness may reveal the presence of progressive glaucoma that, because of green labeling, can be missed by the clinician. Other ocular conditions that can increase RNFL thickness can make the diagnosis of coexisting glaucoma difficult. Recently introduced progression analysis features of OCT may help detect green disease. Recognition of green disease is of paramount importance in diagnosing and treating glaucoma. Understanding the limitations of imaging technologies coupled with evaluation of serial OCT analyses, prompt clinical examination, and structure-function correlation is important to avoid missing real glaucoma requiring treatment.

Detecting and analyzing pathogenic bacteria in an effective and reliable manner is crucial for the diagnosis of acute bacterial infection and initial antibiotic therapy. However, the precise labeling and analysis of bacteria at the single-bacterium level are a technical challenge but very important to reveal important details about the heterogeneity of cells and responds to environment. This study demonstrates an optical strategy for single-bacterium labeling and analysis by the cotrapping of single upconversion nanoparticles (UCNPs) and bacteria together. A single UCNP with an average size of ≈120 nm is first optically trapped. Both ends of a single bacterium are then trapped and labeled with single UCNPs emitting green light. The labeled bacterium can be flexibly moved to designated locations for further analysis. Signals from bacteria of different sizes are detected in real time for single-bacterium analysis. This cotrapping method provides a new approach for single-pathogenic-bacterium labeling, detection, and real-time analysis at the single-particle and single-bacterium level. © 2017 WILEY-VCH Verlag GmbH & Co.

Review of nutrition labeling formats.

PubMed

Geiger, C J; Wyse, B W; Parent, C R; Hansen, R G

1991-07-01

This article examines nutrition labeling history as well as the findings of nine research studies of nutrition labeling formats. Nutrition labeling regulations were announced in 1973 and have been periodically amended since then. In response to requests from consumers and health care professionals for revision of the labeling system, the Food and Drug Administration initiated a three-phase plan for reform of nutrition labeling in 1990. President Bush signed the Nutrition Labeling and Education Act in November 1990. Literature analysis revealed that only nine studies with an experimental design have focused on nutrition labeling since 1971. Four were conducted before 1975, which was the year that nutrition labeling was officially implemented, two were conducted in 1980, and three were conducted after 1986. Only two of the nine studies supported the traditional label format mandated by the Code of Federal Regulations, and one study partially supported it. Four of the nine studies that evaluated graphic presentations of nutrition information found that consumer comprehension of nutrition information was improved with a graphic format for nutrition labeling: three studies supported the use of bar graphs and one study supported the use of a pie chart. Full disclosure (ie, complete nutrient and ingredient labeling) was preferred by consumers in two of the three studies that examined this variable. The third study supported three types of information disclosure dependent upon socioeconomic class. In those studies that tested graphics, a bar graph format was significantly preferred and showed better consumer comprehension than the traditional format.

Defining success in clinical trials--profiling pregabalin, the newest AED.

2005-11-01

The efficacy and safety of pregabalin as adjunctive therapy for patients with partial epilepsy with or without secondary generalization has been established by four randomized, 12-week, double-blind, placebo-controlled trials (n = 1396) and four long-term open-label studies (n = 1480). Patients in the three fixed-dose trials were >/=12 years of age, had >/=6 partial seizures and no 4-week seizure-free period during the 8-week baseline period. Seventy-three per cent of patients were taking >/=2 concomitant antiepileptic drugs. Responder rates across the effective doses (150-600 mg/day) ranged from 14% to 51% and demonstrated a significant dose-response relationship. The most common adverse events were central nervous system related, generally mild or moderate, transient, and tended to be dose related. The fourth placebo-controlled trial compared a fixed dose of pregabalin 600 mg/day with a flexible-dose regimen (150-600 mg/day). Responder rates were greater for both the fixed dose (45.3%, P < 0.001) and flexible dose (31.3%, P < 0.001) when compared with placebo (11.0%). Compared with the fixed-dose group, the flexible-dose patients had a lower incidence of adverse events and study discontinuations. In long-term open-label trials, the efficacy of pregabalin was maintained with respect to 50% responder rates suggesting no obvious tolerance developing over 2 years. Seizure-free rates were 8.9% and 5.8% for the last 6 months and 1 year of pregabalin treatment, respectively. Long-term open-label pregabalin treatment was well tolerated.

UK consumer perceptions of a novel till-receipt 'traffic-light' nutrition system.

PubMed

2018-03-26

Front-of-pack (FoP) traffic light nutrition labelling has been widely proposed as a tool to improve public health nutrition. Current evidence suggests that whilst consumers generally find them to be useful and an important source of information about a particular food or ingredient, this may have limited value in isolation when considering a person's overall nutritional intake. This study sought to examine UK consumers' use of existing FoP traffic light food labelling and ascertain public perception of a novel 'till-receipt' summary providing nutritional information about consumers entire shopping purchases. In total, 237 respondents completed an online questionnaire between May and June 2016. Almost two-thirds were female (n = 152, 64.1%) and the largest proportion of responses were received from those aged 25-32 years (n = 53, 22.4%) and 41-50 years (n = 53, 22.4%). About 83.5% of respondents suggested that they currently use traffic light information to inform their food purchases and 'health' was reported as the most important factor influencing food choice (42.2%; n = 100). Notably, 54.4% of respondents indicated that the novel till-receipt system could provide a solution to the potential limitations of existing FoP labelling and could help inform healthier food purchases. Our findings strengthen the existing evidence base to suggest that traffic light information is a useful tool to aid consumer food purchases. Moreover, our outcomes propose that consumers may benefit from a new receipt-based traffic light system which provides a more holistic summary of their entire food purchases.

Health outcomes and self-labeling as a victim of workplace bullying.

Vie, Tina Løkke; Glasø, Lars; Einarsen, Ståle

2011-01-01

This study investigated the extent to which self-labeling as a victim of workplace bullying mediates or moderates the relationship between exposure to bullying and the target's health outcomes. Data were collected by means of anonymous self-report questionnaires. A total of 1024 employees in a transport organization participated in the study, among whom 116 self-labeled victims were identified. Exposure to bullying was measured by a short version of the Negative Acts Questionnaire, while the respondents' health outcomes were measured by the Bergen Health Checklist. The findings showed that self-labeling both moderated and partially mediated the relationship between exposure to bullying and the targets' health. However, the moderator analyses indicate that self-labeling only acts as moderator in cases of low exposure. Intense exposure to bullying behaviors is related to increased levels of health complaints regardless of the target's subjective appraisal of being a victim or not. Self-labeling as a victim plays an important role in the victimizing process, although persistent exposure to workplace bullying seems to have considerable harmful effects on the target's health independently of whether the experience is labeled as bullying or not.

This study examined illness beliefs of the lay public associated with the diagnostic labels burnout and depression. Representative population survey in Germany 2011, using unlabelled case vignettes of a person suffering from depression. Following presentation of the vignette, respondents were asked openly how they would call the problem described. Agreement with various illness beliefs was elicited with Likert-scaled items. Seeing the problem as inherited predicted use of the label depression (OR 1.29, p < 0.001), while stress at work as a perceived cause was associated with use of the label burnout (OR 1.56, p < 0.001). Belief that the problem described resembled everyday experiences (belief in a symptom continuum) also predicted using the label burnout instead of depression (OR 1.31, p < 0.05). Although overlapping with beliefs about depression, the diagnostic label burnout is also associated with specific illness beliefs among the general public. © Georg Thieme Verlag KG Stuttgart · New York.

Labeled graphs are widely used to model complex data in many domains, so subgraph querying has been attracting more and more attention from researchers around the world. Unfortunately, subgraph querying is very time consuming since it involves subgraph isomorphism testing that is known to be an NP-complete problem. In this paper, we propose a novel coding method for subgraph querying that is based on Laplacian spectrum and the number of walks. Our method follows the filtering-and-verification framework and works well on graph databases with frequent updates. We also propose novel two-step filtering conditions that can filter out most false positives and prove that the two-step filtering conditions satisfy the no-false-negative requirement (no dismissal in answers). Extensive experiments on both real and synthetic graphs show that, compared with six existing counterpart methods, our method can effectively improve the efficiency of subgraph querying.

Despite having many key roles in cellular biology, directly imaging biologically important RNAs has been hindered by a lack of fluorescent tools equivalent to the fluorescent proteins available to study cellular proteins. Ideal RNA labelling systems must preserve biological function, have photophysical properties similar to existing fluorescent proteins, and be compatible with established live and fixed cell protein labelling strategies. Here, we report a microfluidics-based selection of three new high-affinity RNA Mango fluorogenic aptamers. Two of these are as bright or brighter than enhanced GFP when bound to TO1-Biotin. Furthermore, we show that the new Mangos can accurately image the subcellular localization of three small non-coding RNAs (5S, U6, and a box C/D scaRNA) in fixed and live mammalian cells. These new aptamers have many potential applications to study RNA function and dynamics both in vitro and in mammalian cells.

Choice of rating scale labels: implication for minimizing patient satisfaction response ceiling effect in telemedicine surveys.

PubMed

Masino, Caterina; Lam, Tony C M

2014-12-01

Lack of response variability is problematic in surveys because of its detrimental effects on sensitivity and consequently reliability of the responses. In satisfaction surveys, this problem is caused by the ceiling effect resulting from high satisfaction ratings. A potential solution strategy is to manipulate the labels of the rating scale to create greater discrimination of responses on the high end of the response continuum. This study examined the effects of a positive-centered scale on the distribution and reliability of telemedicine satisfaction responses in a highly positive respondent population. In total, 216 telemedicine participants were randomly assigned to one of three experimental conditions as defined by the form of Likert scale: (1) 5-point Balanced Equal-Interval, (2) 5-point Positive-Packed, and (3) 5-point Positive-Centered Equal-Interval. Although the study findings were not statistically significant, partially because of sample size, the distribution and internal consistency reliability of responses occurred in the direction hypothesized. Loading the rating scale with more positive labels appears to be a useful strategy for reducing the ceiling effect and increases the discrimination ability of survey responses. The current research provides a survey design strategy to minimize ceiling effects. Although the findings provide some evidence suggesting the benefit of using rating scales loaded with positive labels, more research is needed to confirm this, as well as extend it to examine other types of rating scales and the interaction between rating scale formats and respondent characteristics.

Little is known about the level of awareness of blindness as a smoking-related condition, although the relationship has been well established. To compare the awareness of smoking risks and the impact of graphic health warning labels on cigarette packs in discouraging smoking among adults in Singapore and Scotland. A cross-sectional survey using a structured interview of adults in ophthalmic, general medical, and general surgical outpatient clinics in Singapore and Scotland. One hundred and fifteen out of 163 (70.6%) outpatients in Singapore and 105 out of 112 (93.8%) outpatients in Scotland responded to the study. In both samples, awareness levels for smoking-related diseases such as lung cancer, mouth and throat cancer, heart disease, and stroke were all greater than 85%. These were found to be significantly higher than the level of awareness of blindness as a smoking-related condition (chi (2)-test, P<0.001). Although the awareness of blindness as a smoking-related condition was greater in Singapore (36.5%) than in Scotland (30.5%), this difference was not statistically significant. More than half of the respondents indicated that graphic health warning labels would be effective in discouraging them from smoking. Graphic health warning labels reading 'Smoking causes blindness' printed on cigarette packs may be useful in raising public awareness of blindness as a smoking-related condition and discouraging the habit of smoking in Singapore and Scotland.

In 1995, the South Korean government made nutrition labeling compulsory, which has positively impacted patients with certain chronic diseases, such as dyslipidemia. We investigated the association between nutrition labeling-based awareness and the risk of dyslipidemia among individuals not yet diagnosed. Our study used data from the fifth Korea National Health and Nutrition Examination Surveys administered during 2010-2014 (n = 17,687). We performed multiple or logistic regression analysis to examine the association between nutritional analysis and various outcome variables. Approximately 70 % of the respondents (n = 11,513) were familiar with nutrition labeling, of which 20 % (n = 3172) decided what food to buy based on that information. This awareness yielded mostly positive results on outcome indicators, such as triglyceride and high-density lipoprotein cholesterol levels. In general, individuals who used nutritional labels to make decisions regarding food purchases had a lower risk of dyslipidemia than individuals who did not (OR: 0.806, 95 % CI: 0.709-0.917). Utilizing nutrition labels for making food choices correlated with a lower risk of dyslipidemia in certain subgroups. Based on our findings, we recommend that health policymakers and medical professionals consider promoting nutrition labeling as an alternative method for managing certain chronic diseases in South Korean patients.

Category-contingent face adaptation for novel colour categories: Contingent effects are seen only after social or meaningful labelling.

PubMed

Little, Anthony C; DeBruine, Lisa M; Jones, Benedict C

2011-01-01

A face appears normal when it approximates the average of a population. Consequently, exposure to faces biases perceptions of subsequently viewed faces such that faces similar to those recently seen are perceived as more normal. Simultaneously inducing such aftereffects in opposite directions for two groups of faces indicates somewhat discrete representations for those groups. Here we examine how labelling influences the perception of category in faces differing in colour. We show category-contingent aftereffects following exposure to faces differing in eye spacing (wide versus narrow) for blue versus red faces when such groups are consistently labelled with socially meaningful labels (Extravert versus Introvert; Soldier versus Builder). Category-contingent aftereffects were not seen using identical methodology when labels were not meaningful or were absent. These data suggest that human representations of faces can be rapidly tuned to code for meaningful social categories and that such tuning requires both a label and an associated visual difference. Results highlight the flexibility of the cognitive visual system to discriminate categories even in adulthood. Copyright © 2010 Elsevier B.V. All rights reserved.

Impacts of phylogenetic nomenclature on the efficacy of the U.S. Endangered Species Act.

PubMed

Leslie, Matthew S

2015-02-01

Cataloging biodiversity is critical to conservation efforts because accurate taxonomy is often a precondition for protection under laws designed for species conservation, such as the U.S. Endangered Species Act (ESA). Traditional nomenclatural codes governing the taxonomic process have recently come under scrutiny because taxon names are more closely linked to hierarchical ranks than to the taxa themselves. A new approach to naming biological groups, called phylogenetic nomenclature (PN), explicitly names taxa by defining their names in terms of ancestry and descent. PN has the potential to increase nomenclatural stability and decrease confusion induced by the rank-based codes. But proponents of PN have struggled with whether species and infraspecific taxa should be governed by the same rules as other taxa or should have special rules. Some proponents advocate the wholesale abandonment of rank labels (including species); this could have consequences for the implementation of taxon-based conservation legislation. I examined the principles of PN as embodied in the PhyloCode (an alternative to traditional rank-based nomenclature that names biological groups based on the results of phylogenetic analyses and does not associate taxa with ranks) and assessed how this novel approach to naming taxa might affect the implementation of species-based legislation by providing a case study of the ESA. The latest version of the PhyloCode relies on the traditional rank-based codes to name species and infraspecific taxa; thus, little will change regarding the main targets of the ESA because they will retain rank labels. For this reason, and because knowledge of evolutionary relationships is of greater importance than nomenclatural procedures for initial protection of endangered taxa under the ESA, I conclude that PN under the PhyloCode will have little impact on implementation of the ESA. © 2014 Society for Conservation Biology.

Task representation in individual and joint settings

PubMed Central

Prinz, Wolfgang

2015-01-01

This paper outlines a framework for task representation and discusses applications to interference tasks in individual and joint settings. The framework is derived from the Theory of Event Coding (TEC). This theory regards task sets as transient assemblies of event codes in which stimulus and response codes interact and shape each other in particular ways. On the one hand, stimulus and response codes compete with each other within their respective subsets (horizontal interactions). On the other hand, stimulus and response code cooperate with each other (vertical interactions). Code interactions instantiating competition and cooperation apply to two time scales: on-line performance (i.e., doing the task) and off-line implementation (i.e., setting the task). Interference arises when stimulus and response codes overlap in features that are irrelevant for stimulus identification, but relevant for response selection. To resolve this dilemma, the feature profiles of event codes may become restructured in various ways. The framework is applied to three kinds of interference paradigms. Special emphasis is given to joint settings where tasks are shared between two participants. Major conclusions derived from these applications include: (1) Response competition is the chief driver of interference. Likewise, different modes of response competition give rise to different patterns of interference; (2) The type of features in which stimulus and response codes overlap is also a crucial factor. Different types of such features give likewise rise to different patterns of interference; and (3) Task sets for joint settings conflate intraindividual conflicts between responses (what), with interindividual conflicts between responding agents (whom). Features of response codes may, therefore, not only address responses, but also responding agents (both physically and socially). PMID:26029085

The effect of illustrations on patient comprehension of medication instruction labels.

PubMed

Hwang, Stephen W; Tram, Carolyn Q N; Knarr, Nadia

2005-06-16

Labels with special instructions regarding how a prescription medication should be taken or its possible side effects are often applied to pill bottles. The goal of this study was to determine whether the addition of illustrations to these labels affects patient comprehension. Study participants (N = 130) were enrolled by approaching patients at three family practice clinics in Toronto, Canada. Participants were asked to interpret two sets of medication instruction labels, the first with text only and the second with the same text accompanied by illustrations. Two investigators coded participants' responses as incorrect, partially correct, or completely correct. Health literacy levels of participants were measured using a validated instrument, the REALM test. All participants gave a completely correct interpretation for three out of five instruction labels, regardless of whether illustrations were present or not. For the two most complex labels, only 34-55% of interpretations of the text-only version were completely correct. The addition of illustrations was associated with improved performance in 5-7% of subjects and worsened performance in 7-9% of subjects. The commonly-used illustrations on the medication labels used in this study were of little or no use in improving patients' comprehension of the accompanying written instructions.

Memory for product sounds: the effect of sound and label type.

PubMed

Ozcan, Elif; van Egmond, René

2007-11-01

The (mnemonic) interactions between auditory, visual, and the semantic systems have been investigated using structurally complex auditory stimuli (i.e., product sounds). Six types of product sounds (air, alarm, cyclic, impact, liquid, mechanical) that vary in spectral-temporal structure were presented in four label type conditions: self-generated text, text, image, and pictogram. A memory paradigm that incorporated free recall, recognition, and matching tasks was employed. The results for the sound type suggest that the amount of spectral-temporal structure in a sound can be indicative for memory performance. Findings related to label type suggest that 'self' creates a strong bias for the retrieval and the recognition of sounds that were self-labeled; the density and the complexity of the visual information (i.e., pictograms) hinders the memory performance ('visual' overshadowing effect); and image labeling has an additive effect on the recall and matching tasks (dual coding). Thus, the findings suggest that the memory performances for product sounds are task-dependent.

Towards objective and reproducible study of patient-doctor interaction: Automatic text analysis based VR-CoDES annotation of consultation transcripts.

While increasingly appreciated for its importance, the interaction between health care professionals (HCP) and patients is notoriously difficult to study, with both methodological and practical challenges. The former has been addressed by the so-called Verona coding definitions of emotional sequences (VR-CoDES) - a system for identifying and coding patient emotions and the corresponding HCP responses - shown to be reliable and informative in a number of independent studies in different health care delivery contexts. In the preset work we focus on the practical challenge of the scalability of this coding system, namely on making it easily usable more widely and on applying it on larger patient cohorts. In particular, VR-CoDES is inherently complex and training is required to ensure consistent annotation of audio recordings or textual transcripts of consultations. Following up on our previous pilot investigation, in the the present paper we describe the first automatic, computer based algorithm capable of providing coarse level coding of textual transcripts. We investigate different representations of patient utterances and classification methodologies, and label each utterance as either containing an explicit expression of emotional distress (a `concern'), an implicit one (a `cue'), or neither. Using a data corpus comprising 200 consultations between radiotherapists and adult female breast cancer patients we demonstrate excellent labelling performance.

Ontological function annotation of long non-coding RNAs through hierarchical multi-label classification.

Long non-coding RNAs (lncRNAs) are an enormous collection of functional non-coding RNAs. Over the past decades, a large number of novel lncRNA genes have been identified. However, most of the lncRNAs remain function uncharacterized at present. Computational approaches provide a new insight to understand the potential functional implications of lncRNAs. Considering that each lncRNA may have multiple functions and a function may be further specialized into sub-functions, here we describe NeuraNetL2GO, a computational ontological function prediction approach for lncRNAs using hierarchical multi-label classification strategy based on multiple neural networks. The neural networks are incrementally trained level by level, each performing the prediction of gene ontology (GO) terms belonging to a given level. In NeuraNetL2GO, we use topological features of the lncRNA similarity network as the input of the neural networks and employ the output results to annotate the lncRNAs. We show that NeuraNetL2GO achieves the best performance and the overall advantage in maximum F-measure and coverage on the manually annotated lncRNA2GO-55 dataset compared to other state-of-the-art methods. The source code and data are available at http://denglab.org/NeuraNetL2GO/. leideng@csu.edu.cn. Supplementary data are available at Bioinformatics online.

An international survey of building energy codes and their implementation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Evans, Meredydd; Roshchanka, Volha; Graham, Peter

Buildings are key to low-carbon development everywhere, and many countries have introduced building energy codes to improve energy efficiency in buildings. Yet, building energy codes can only deliver results when the codes are implemented. For this reason, studies of building energy codes need to consider implementation of building energy codes in a consistent and comprehensive way. This research identifies elements and practices in implementing building energy codes, covering codes in 22 countries that account for 70% of global energy demand from buildings. Access to benefits of building energy codes depends on comprehensive coverage of buildings by type, age, size, andmore » geographic location; an implementation framework that involves a certified agency to inspect construction at critical stages; and independently tested, rated, and labeled building energy materials. Training and supporting tools are another element of successful code implementation, and their role is growing in importance, given the increasing flexibility and complexity of building energy codes. Some countries have also introduced compliance evaluation and compliance checking protocols to improve implementation. This article provides examples of practices that countries have adopted to assist with implementation of building energy codes.« less

The two voices of Alzheimer's: attitudes toward brain health by diagnosed individuals and support persons.

Beard, Renée L; Fetterman, David J; Wu, Bei; Bryant, Lucinda

2009-06-01

Most individuals with Alzheimer's are cared for in their homes by unpaid family members. Research on caregiving focuses disproportionally on costs of care, service utilization, and negative psychosocial outcomes. Few narrative accounts of Alzheimer's exist; those that do suffer similar pejorative framings and narrow foci. No studies that we are aware of examine the health beliefs of diagnosed individuals and support persons, or their attitudes about brain health. This research reports perceptions of "aging well" held by those most intimately acquainted with Alzheimer's. Diagnosed individuals and their support persons (N = 85) were enrolled into 14 focus groups. Grounded theory methods were used to collect, code, and analyze textual interview data into overarching themes. Respondents found physical and mental health, social activity, independence, and happiness integral to aging well. An acceptance of various limitations was also deemed crucial. Support persons placed more emphasis on lifestyle factors and memory loss as potential obstacles. Diagnosed respondents defined memory loss in less medicalized terms, whereas support persons labeled it Alzheimer's and negatively characterized those affected. Both groups warned against discussing "prevention" of dementia: Diagnosed individuals noted the implication of "aging poorly" and support persons cautioned against blaming diagnosed individuals. These findings can be used to encourage positive health beliefs and behaviors tailored to the needs of diagnosed seniors and their families, to help practitioners and researchers identify and become sensitive to differences between and among older adults, and to further advance the utility of narrative accounts for informing health interventions and education efforts.

2017-01-01

The implementation of a standardized front-of-pack-labelling (FoPL) scheme would likely be a useful tool for many consumers trying to improve the healthfulness of their diets. Our objective was to examine what the traffic light labelling scheme would look like if implemented in the US. Data were extracted from Label Insight’s Open Access branded food database in 2017. Nutrient levels and the proportion of products classified as “Red” (High), “Amber” (Medium) or “Green” (Low) in total fat, saturated fat, total sugar and sodium for food and beverage items were examined. The proportion of products in each category that had each possible combination of traffic light colors, and met the aggregate score for “healthy” was examined. Out of 175,198 products, >50% of all US packaged foods received a “Red” rating for total sugar and sodium. “Confectionery” had the highest mean total sugar (51.9 g/100 g) and “Meat and meat alternatives” the highest mean sodium (781 mg/100 g). The most common traffic light label combination was “Red” for total fat, saturated fat and sodium and “Green” for sugar. Only 30.1% of products were considered “healthy”. A wide variety (n = 80) of traffic light color combinations were observed. A color coded traffic light scheme appears to be an option for implementation across the US packaged food supply to support consumers in making healthier food choices. PMID:28489037

2015-02-01

Use of nutrition labels in food selection is recommended for consumers. The aim of this study is to examine factors, mainly beliefs explaining nutrition label use in female college students based on the Theory of Planned Behavior (TPB). The subjects were female college students from a university in Seoul, Korea. The survey questionnaire was composed of items examining general characteristics, nutrition label use, behavioral beliefs, normative beliefs, corresponding motivation to comply, and control beliefs. The subjects (n = 300) responded to the questionnaire by self-report, and data from 275 students were analyzed using t-test or χ(2)-test. The results showed that 37.8% of subjects were nutrition label users. Three out of 15 behavioral beliefs differed significantly by nutrition label use. Nutrition label users agreed more strongly on the benefits of using nutrition labels including 'comparing and selecting better foods' (P < 0.001), 'selecting healthy foods' (P < 0.05). The negative belief of 'annoying' was stronger in non-users than in users (P < 0.001). Three out of 7 sources (parents, siblings, best friend) were important in nutrition label use. Twelve out of 15 control beliefs differed significantly by nutrition label use. These included beliefs regarding constraints of using nutrition labels (e.g., time, spending money for healthy foods) and lack of nutrition knowledge (P < 0.001). Perceived confidence in understanding and applying the specifics of nutrition labels in food selection was also significantly related to nutrition label use (P < 0.001). This study found that the beliefs, especially control beliefs, suggested in the TPB were important in explaining nutrition label use. To promote nutrition label use, nutrition education might focus on increasing perceived control over constraints of using nutrition labels, acquiring skills for checking nutrition labels, as well as the benefits of using nutrition labels and receiving support from significant others for nutrition label use.

Inter-individual differences in how presentation modality affects verbal learning performance in children aged 5 to 16.

Meijs, Celeste; Hurks, Petra P M; Wassenberg, Renske; Feron, Frans J M; Jolles, Jelle

2016-01-01

This study examines inter-individual differences in how presentation modality affects verbal learning performance. Children aged 5 to 16 performed a verbal learning test within one of three presentation modalities: pictorial, auditory, or textual. The results indicated that a beneficial effect of pictures exists over auditory and textual presentation modalities and that this effect increases with age. However, this effect is only found if the information to be learned is presented once (or at most twice) and only in children above the age of 7. The results may be explained in terms of single or dual coding of information in which the phonological loop is involved. Development of the (sub)vocal rehearsal system in the phonological loop is believed to be a gradual process that begins developing around the age of 7. The developmental trajectories are similar for boys and girls. Additionally, auditory information and textual information both seemed to be processed in a similar manner, namely without labeling or recoding, leading to single coding. In contrast, pictures are assumed to be processed by the dual coding of both the visual information and a (verbal) labeling of the pictures.

2015-10-01

To determine whether food label information and advertisements for foods containing no fruit cause children to have a false impression of the foods' fruit content. In the food label condition, a trained researcher showed each child sixteen different food label photographs depicting front-of-food label packages that varied with regard to fruit content (i.e. real fruit v. sham fruit) and label elements. In the food advertisement condition, children viewed sixteen, 30 s television food advertisements with similar fruit content and label elements as in the food label condition. After viewing each food label and advertisement, children responded to the question 'Did they use fruit to make this?' with responses of yes, no or don't know. Schools, day-care centres, after-school programmes and other community groups. Children aged 4-7 years. In the food label condition, χ 2 analysis of within fruit content variation differences indicated children (n 58; mean age 4·2 years) were significantly more accurate in identifying real fruit foods as the label's informational load increased and were least accurate when neither a fruit name nor an image was on the label. Children (n 49; mean age 5·4 years) in the food advertisement condition were more likely to identify real fruit foods when advertisements had fruit images compared with when no image was included, while fruit images in advertisements for sham fruit foods significantly reduced accuracy of responses. Findings suggest that labels and advertisements for sham fruit foods mislead children with regard to the food's real fruit content.

Do consumers 'Get the facts'? A survey of alcohol warning label recognition in Australia.

Coomber, Kerri; Martino, Florentine; Barbour, I Robert; Mayshak, Richelle; Miller, Peter G

2015-08-22

There is limited research on awareness of alcohol warning labels and their effects. The current study examined the awareness of the Australian voluntary warning labels, the 'Get the facts' logo (a component of current warning labels) that directs consumers to an industry-designed informational website, and whether alcohol consumers visited this website. Participants aged 18-45 (unweighted n = 561; mean age = 33.6 years) completed an online survey assessing alcohol consumption patterns, awareness of the 'Get the facts' logo and warning labels, and use of the website. No participants recalled the 'Get the facts' logo, and the recall rate of warning labels was 16% at best. A quarter of participants recognised the 'Get the facts' logo, and awareness of the warning labels ranged from 13.1-37.9%. Overall, only 7.3% of respondents had visited the website. Multivariable logistic regression models indicated that younger drinkers, increased frequency of binge drinking, consuming alcohol directly from the bottle or can, and support for warning labels were significantly, positively associated with awareness of the logo and warning labels. While an increased frequency of binge drinking, consuming alcohol directly from the container, support for warning labels, and recognition of the 'Get the facts' logo increased the odds of visiting the website. Within this sample, recall of the current, voluntary warning labels on Australian alcohol products was non-existent, overall awareness was low, and few people reported visiting the DrinkWise website. It appears that current warning labels fail to effectively transmit health messages to the general public.

The aim of this study was to describe and evaluate an approach for improving radiopharmaceutical supply chain safety by implementing bar code technology. We first evaluated the current situation of our radiopharmaceutical supply chain and, by means of the ALARM protocol, analysed two dispensing errors that occurred in our department. Thereafter, we implemented a bar code system to secure selected key stages of the radiopharmaceutical supply chain. Finally, we evaluated the cost of this implementation, from overtime, to overheads, to additional radiation exposure to workers. An analysis of the events that occurred revealed a lack of identification of prepared or dispensed drugs. Moreover, the evaluation of the current radiopharmaceutical supply chain showed that the dispensation and injection steps needed to be further secured. The bar code system was used to reinforce product identification at three selected key stages: at usable stock entry; at preparation-dispensation; and during administration, allowing to check conformity between the labelling of the delivered product (identity and activity) and the prescription. The extra time needed for all these steps had no impact on the number and successful conduct of examinations. The investment cost was reduced (2600 euros for new material and 30 euros a year for additional supplies) because of pre-existing computing equipment. With regard to the radiation exposure to workers there was an insignificant overexposure for hands with this new organization because of the labelling and scanning processes of radiolabelled preparation vials. Implementation of bar code technology is now an essential part of a global securing approach towards optimum patient management.

Comprehension of hazard communication: effects of pictograms on safety data sheets and labels.

The United Nations has proposed the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals to make hazard communication more uniform and to improve comprehension. Two experiments were conducted to test whether the addition of hazard and precautionary pictograms to safety data sheets and product labels would improve the transfer of information to users compared to safety data sheets and product labels containing text only. Additionally, naïve users, workers, and experts were tested to determine any potential differences among users. The effect of adding pictograms to safety data sheets and labels was statistically significant for some conditions, but was not significant across all conditions. One benefit of the addition of pictograms was that the time to respond to the survey questions decreased when the pictograms were present for both the SDS and the labels. GHS format SDS and labels do provide benefits to users, but the system will need further enhancements and modifications to continue to improve the effectiveness of hazard communication. The final rule to modify the HCS to include the Globally Harmonized System (GHS) for the Classification and Labelling of Chemicals announced by OSHA (2012b) will change the information content of every chemical SDS and label used in commerce. This study suggests that the inclusion of GHS hazard pictograms and precautionary pictograms to SDS and labels may benefit the user. Copyright © 2013 National Safety Council and Elsevier Ltd.

This paper is concerned with the effects of cigarette pack warning labels on quitting intentions. We examined whether different responses among smokers toward cigarette pack warning labels could predict quit intentions and self-efficacy in quitting. Variables studied were "noticing warning labels during last month," "reading or looking closely at warning labels," "avoiding looking at labels during last month," "thinking about health risks of smoking because of the warning labels, "more likely to quit because of the warning labels," and "stopping from having a cigarette when about to smoke one because of the labels." A total of 2,006 adult smokers in Malaysia were surveyed in face-to-face interviews using a standardized questionnaire. Of those, 1,919 male smokers were included in the analyses. The responses "more likely to quit because of the warning labels" and "stopped from having a cigarette when about to smoke one" significantly predicted all stages of change and self-efficacy, independent of the other measures. In addition, thinking about the health risks and reading the warnings more often added extra predictive capacity but only in the early stages of contemplating change. Less intense processing of the information may be important in initiating thoughts, but cognitions about quitting and foregoing cigarettes are the key mechanisms by which warnings stimulate quitting intentions and help smokers feel capable of succeeding. Malaysian smokers appear to respond to warnings in ways comparable with those from developed countries.

Progress in development of an integrated dietary supplement ingredient database at the NIH Office of Dietary Supplements

Several activities of the Office of Dietary Supplements (ODS) at the National Institutes of Health involve enhancement of dietary supplement databases. These include an initiative with US Department of Agriculture to develop an analytically substantiated dietary supplement ingredient database (DSID) and collaboration with the National Center for Health Statistics to enhance the dietary supplement label database in the National Health and Nutrition Examination Survey (NHANES). The many challenges that must be dealt with in developing an analytically supported DSID include categorizing product types in the database, identifying nutrients, and other components of public health interest in these products and prioritizing which will be entered in the database first. Additional tasks include developing methods and reference materials for quantifying the constituents, finding qualified laboratories to measure the constituents, developing appropriate sample handling procedures, and finally developing representative sampling plans. Developing the NHANES dietary supplement label database has other challenges such as collecting information on dietary supplement use from NHANES respondents, constant updating and refining of information obtained, developing default values that can be used if the respondent cannot supply the exact supplement or strength that was consumed, and developing a publicly available label database. Federal partners and the research community are assisting in making an analytically supported dietary supplement database a reality. PMID:25309034

2016-04-01

Up to 30% of patients with cutaneous lupus erythematosus (CLE) fail to respond to hydroxychloroquine (HCQ). We sought to evaluate the efficacy of increased daily doses of HCQ on cutaneous response in refractory CLE. We conducted an open-label prospective study between 2010 and 2014. Patients with CLE and HCQ blood level less than or equal to 750 ng/mL were included. The daily dose of HCQ was increased to reach blood concentrations greater than 750 ng/mL. The primary end point was the number of responders defined by an improvement of CLE Disease Area and Severity Index score (4 points or 20% decrease) in patients with HCQ blood concentration greater than 750 ng/mL. We included 34 patients (26 women; median age 45 [range 28-72] years). Two nonadherent patients were excluded. The median CLE Disease Area and Severity Index score before treatment was significantly improved after treatment (8 [range 2-30] vs 1.5 [range 0-30]), P < .001). The primary response criterion was reached in 26 (81%) of the 32 patients analyzed. A decrease in HCQ doses without further CLE flare (median follow-up 15.8 [range 3.06-77.4] months) was achieved in 15 of the 26 responders. The main limitations of the study are its open-label design and the limited number of patients included. Increasing HCQ doses to reach blood concentrations greater than 750 ng/mL should be considered before addition of other treatments in refractory CLE.

To evaluate potential development of tolerance to adjunctive clobazam in patients with Lennox-Gastaut syndrome. Eligible patients enrolled in open-label extension study OV-1004, which continued until clobazam was commercially available in the United States or for a maximum of 2 years outside the United States. Enrolled patients started at 0.5 mg·kg -1 ·d -1 clobazam, not to exceed 40 mg/d. After 48 hours, dosages could be adjusted up to 2.0 mg·kg -1 ·d -1 (maximum 80 mg/d) on the basis of efficacy and tolerability. Post hoc analyses evaluated mean dosages and drop-seizure rates for the first 2 years of the open-label extension based on responder categories and baseline seizure quartiles in OV-1012. Individual patient listings were reviewed for dosage increases ≥40% and increasing seizure rates. Data from 200 patients were included. For patients free of drop seizures, there was no notable change in dosage over 24 months. For responder groups still exhibiting drop seizures, dosages were increased. Weekly drop-seizure rates for 100% and ≥75% responders demonstrated a consistent response over time. Few patients had a dosage increase ≥40% associated with an increase in seizure rates. Two-year findings suggest that the majority of patients do not develop tolerance to the antiseizure actions of clobazam. Observed dosage increases may reflect best efforts to achieve seizure freedom. It is possible that the clinical development of tolerance to clobazam has been overstated. NCT00518713 and NCT01160770. This study provides Class III evidence that the majority of patients do not develop tolerance to clobazam over 2 years of treatment. © 2016 American Academy of Neurology.

To clarify preferred labels for people receiving health care. The proper label to describe people receiving care has evoked considerable debate among providers and bio-ethicists, but there is little evidence as to the preferences of the people involved. We analysed dictionary definitions as to the derivation and connotations of such potential labels as: patient, client, customer, consumer, partner and survivor. We then surveyed outpatients from four clinical populations in Ontario, Canada about their feelings about these labels. People from breast cancer (n = 202), prostate disease (n = 202) and fracture (n = 202) clinics in an urban Canadian teaching hospital (Sharpe study), and people with HIV/AIDS at 10 specialty care clinics and three primary care practices affiliated with the HIV Ontario Observational Database (n = 431). VARIABLES AND OUTCOME MEASURES: The survey instruments included questions about opinion of label, role in treatment decision-making (the Problem Solving Decision Making scale), trust, use of information and health status. Our respondents moderately liked the label 'patient'. The other alternatives evoked moderate to strong dislike. Many alternatives to 'patient' incorporate assumptions (e.g. a market relationship) which care recipients may also find objectionable. People who are receiving care find the label 'patient' much less objectionable than the alternatives that have been suggested.

Campylobacter is the leading cause of bacterial gastroenteritis worldwide, and contaminated chicken is a significant vehicle for spread of the disease. This study aimed to assess consumers' knowledge of safe chicken handling practices and whether their expectations for food safety labelling of chicken are met, as a strategy to prevent campylobacteriosis. We conducted a cross-sectional survey of 401 shoppers at supermarkets and butcheries in Wellington, New Zealand, and a systematic assessment of content and display features of chicken labels. While 89% of participants bought, prepared or cooked chicken, only 15% knew that most (60-90%) fresh chicken in New Zealand is contaminated by Campylobacter. Safety and correct preparation information on chicken labels, was rated 'very necessary' or 'essential' by the majority of respondents. Supermarket chicken labels scored poorly for the quality of their food safety information with an average of 1.7/5 (95% CI, 1.4-2.1) for content and 1.8/5 (95% CI, 1.6-2.0) for display. Most consumers are unaware of the level of Campylobacter contamination on fresh chicken and there is a significant but unmet consumer demand for information on safe chicken preparation on labels. Labels on fresh chicken products are a potentially valuable but underused tool for campylobacteriosis prevention in New Zealand.

To explore the perceived effectiveness of pictorial health warning (PHW) labels required by the Gulf Cooperation Council, to compare them with the Food and Drug Administration-approved PHW labels, and to determine factors affecting their perceived effectiveness. A cross-sectional study using a convenience sample of adult smokers and nonsmokers was conducted. The data were collected through a self-administered online questionnaire. The perceived effectiveness scores of PHW labels were calculated and compared among different subgroups using the Kruskal-Wallis test and the Dunn multiple comparison test at a .05 significance level. Of the 90 people invited to participate in the survey, 77 (86%) completed it, with 39 (50%) nonsmokers, 22 (29%) smokers, and 16 (21%) former smokers. Overall, labels having graphic images of illness or pathology are perceived to be most effective. Smokers generally perceived labels significantly less effective compared with former smokers and nonsmokers. Also, 55 respondents (71%) suggested that the presence of a telephone quit-line would be effective. Smoking status and image type had the most effect on the perceived effectiveness of the PHW labels on cigarette packs. Pictorial health warning labels with graphic images of pathology and a telephone quit-line are perceived to be most effective.

Restaurant menu labeling laws and alcohol use.

Restrepo, Brandon J; Ali, Mir M

The goal of this study was to analyze the effect of local and state mandatory restaurant menu labeling laws on alcohol use. Using a difference-in-differences estimation approach and data on adults aged 21 and older (n=2,157,722) from the 2002-2012 Behavioral Risk Factor Surveillance System, we estimated the effect of menu labeling laws on self-reported consumption of alcoholic beverages in the past month. The regression analysis indicates that on average implementation of menu labeling laws is associated with a 1.2 percentage-point drop in the fraction of survey respondents reporting that they drank an alcoholic beverage in the past month (95% confidence interval=-0.020, -0.004), compared with jurisdictions that had not implemented menu labeling laws. Moreover, we find that the estimated policy effects on alcohol use are larger among men than among women and larger among minorities than among non-Hispanic whites. Further provision of calorie information on foods and beverages in food service establishments, such as through federal menu labeling regulations, may have the potential to lead to a meaningful reduction in alcohol use throughout the U.S. and may result in larger reductions in alcohol use among men and minorities.

Buildings are key to low-carbon development everywhere, and many countries have introduced building energy codes to improve energy efficiency in buildings. Yet, building energy codes can only deliver results when the codes are implemented. For this reason, studies of building energy codes need to consider implementation of building energy codes in a consistent and comprehensive way. This research identifies elements and practices in implementing building energy codes, covering codes in 22 countries that account for 70% of global energy use in buildings. These elements and practices include: comprehensive coverage of buildings by type, age, size, and geographic location; an implementationmore » framework that involves a certified agency to inspect construction at critical stages; and building materials that are independently tested, rated, and labeled. Training and supporting tools are another element of successful code implementation. Some countries have also introduced compliance evaluation studies, which suggested that tightening energy requirements would only be meaningful when also addressing gaps in implementation (Pitt&Sherry, 2014; U.S. DOE, 2016b).

Labelling effects and adolescent responses to peers with depression: an experimental investigation.

PubMed

Dolphin, Louise; Hennessy, Eilis

2017-06-24

The impact of illness labels on the stigma experiences of individuals with mental health problems is a matter of ongoing debate. Some argue that labels have a negative influence on judgments and should be avoided in favour of information emphasising the existence of a continuum of mental health/illness. Others believe that behavioral symptoms are more powerful influencers of stigma than labels. The phenomenon has received little attention in adolescent research, despite the critical importance of the peer group at this developmental stage. This study employs a novel experimental design to examine the impact of the depression label and continuum information on adolescents' responses to peers with depression. Participants were 156 adolescents, 76 male, 80 female (M = 16.25 years; SD = .361), assigned to one of three conditions (Control, Label, Continuum). Participants respond to four audio-visual vignette characters (two clinically depressed) on three occasions. Outcome measures included judgment of the mental health of the vignette characters and emotional responses to them. Neither the provision of a depression label or continuum information influenced perceptions of the mental health of the characters in the audio-visual vignettes or participants' emotional responses to them. The findings have implications for the design of interventions to combat depression stigma with adolescents. Interventions should not necessarily target perceptions of psychiatric labels, but rather perceptions of symptomatic behaviour.

A Character Segmentation Proposal for High-Speed Visual Monitoring of Expiration Codes on Beverage Cans.

2016-04-13

Expiration date labels are ubiquitous in the food industry. With the passage of time, almost any food becomes unhealthy, even when well preserved. The expiration date is estimated based on the type and manufacture/packaging time of that particular food unit. This date is then printed on the container so it is available to the end user at the time of consumption. MONICOD (MONItoring of CODes); an industrial validator of expiration codes; allows the expiration code printed on a drink can to be read. This verification occurs immediately after printing. MONICOD faces difficulties due to the high printing rate (35 cans per second) and problematic lighting caused by the metallic surface on which the code is printed. This article describes a solution that allows MONICOD to extract shapes and presents quantitative results for the speed and quality.

Development of structured ICD-10 and its application to computer-assisted ICD coding.

This paper presents: (1) a framework of formal representation of ICD10, which functions as a bridge between ontological information and natural language expressions; and (2) a methodology to use formally described ICD10 for computer-assisted ICD coding. First, we analyzed and structurized the meanings of categories in 15 chapters of ICD10. Then we expanded the structured ICD10 (S-ICD10) by adding subordinate concepts and labels derived from Japanese Standard Disease Names. The information model to describe formal representation was refined repeatedly. The resultant model includes 74 types of semantic links. We also developed an ICD coding module based on S-ICD10 and a 'Coding Principle,' which achieved high accuracy (>70%) for four chapters. These results not only demonstrate the basic feasibility of our coding framework but might also inform the development of the information model for formal description framework in the ICD11 revision.

Medicalizing versus psychologizing mental illness: what are the implications for help seeking and stigma? A general population study.

PubMed

Pattyn, E; Verhaeghe, M; Sercu, C; Bracke, P

2013-10-01

This study contrasts the medicalized conceptualization of mental illness with psychologizing mental illness and examines what the consequences are of adhering to one model versus the other for help seeking and stigma. The survey "Stigma in a Global Context-Belgian Mental Health Study" (2009) conducted face-to-face interviews among a representative sample of the general Belgian population using the vignette technique to depict schizophrenia (N = 381). Causal attributions, labeling processes, and the disease view are addressed. Help seeking refers to open-ended help-seeking suggestions (general practitioner, psychiatrist, psychologist, family, friends, and self-care options). Stigma refers to social exclusion after treatment. The data are analyzed by means of logistic and linear regression models in SPSS Statistics 19. People who adhere to the biopsychosocial (versus psychosocial) model are more likely to recommend general medical care and people who apply the disease view are more likely to recommend specialized medical care. Regarding informal help, those who prefer the biopsychosocial model are less likely to recommend consulting friends than those who adhere to the psychosocial model. Respondents who apply a medical compared to a non-medical label are less inclined to recommend self-care. As concerns treatment stigma, respondents who apply a medical instead of a non-medical label are more likely to socially exclude someone who has been in psychiatric treatment. Medicalizing mental illness involves a package deal: biopsychosocial causal attributions and applying the disease view facilitate medical treatment recommendations, while labeling seems to trigger stigmatizing attitudes.

How do researchers categorize drugs, and how do drug users categorize them?

This paper considers drug classifications and terms widely used in US survey research, and compares these to classifications and terms used by drug users. We begin with a critical review of drug classification systems, including those oriented to public policy and health services as well as survey research. We then consider the results of a pile sort exercise we conducted with 76 respondents within a mixed method study of Southeast Asian American adolescent and young adult drug users in urban Northern California, USA. We included the pile sort to clarify how respondents handled specific terms which we understood to be related to Ecstasy and methamphetamines. Results of the pile sort were analyzed using graphic layout algorithms as well as content analysis of pile labels. Similar to the national surveys, our respondents consistently differentiated Ecstasy terms from methamphetamine terms. We found high agreement between some specific local terms (thizz, crystal) and popular drug terms, while other terms thought to be mainstream (crank, speed) were reported as unknown by many respondents. In labeling piles, respondents created taxonomies based on consumption method (in particular, pill) as well as the social contexts of use. We conclude by proposing that divergences between drug terms utilized in survey research and those used by drug users may reflect two opposing tendencies: the tendency of survey researchers to utilize standardized language that constructs persons and experiences as relatively homogeneous, varying only within measurable degrees, and the tendency of drug users to utilize specialized language (argot) that reflects their understandings of their experiences as hybrid and diverse. The findings problematize the validity of drug terms and categories used in survey research. PMID:24431475

Treatment response and side effects of venlafaxine were evaluated in an open-label trial of elderly outpatients with dysthymic disorder (DD). Patients received flexible dose (up to 300 mg/d) venlafaxine (Effexor XR) for 12 weeks. Of 23 study patients, 18 completed the trial. Fourteen (60.9%) were responders in intent-to-treat analyses with the last observation carried forward, and 77.8% were responders in completer analyses. Nearly half the sample (47.8%) met criteria for remission. In the intent-to-treat sample, increased severity of depression at baseline was associated with superior response, and the presence of cardiovascular disease was associated with poorer response. Venlafaxine open-label treatment was associated with fairly high response rates and generally good tolerability in elderly patients with DD. These results indicate that in elderly patients with DD, placebo-controlled trials of a dual reuptake inhibitor such as venlafaxine would be needed to assess its efficacy or to compare its efficacy to that of other antidepressants.

The effect of illustrations on patient comprehension of medication instruction labels

PubMed Central

Hwang, Stephen W; Tram, Carolyn QN; Knarr, Nadia

2005-01-01

Background Labels with special instructions regarding how a prescription medication should be taken or its possible side effects are often applied to pill bottles. The goal of this study was to determine whether the addition of illustrations to these labels affects patient comprehension. Methods Study participants (N = 130) were enrolled by approaching patients at three family practice clinics in Toronto, Canada. Participants were asked to interpret two sets of medication instruction labels, the first with text only and the second with the same text accompanied by illustrations. Two investigators coded participants' responses as incorrect, partially correct, or completely correct. Health literacy levels of participants were measured using a validated instrument, the REALM test. Results All participants gave a completely correct interpretation for three out of five instruction labels, regardless of whether illustrations were present or not. For the two most complex labels, only 34–55% of interpretations of the text-only version were completely correct. The addition of illustrations was associated with improved performance in 5–7% of subjects and worsened performance in 7–9% of subjects. Conclusion The commonly-used illustrations on the medication labels used in this study were of little or no use in improving patients' comprehension of the accompanying written instructions.

In mammals, taste buds typically contain 50-100 tightly packed taste-receptor cells (TRCs), representing all five basic qualities: sweet, sour, bitter, salty and umami. Notably, mature taste cells have life spans of only 5-20 days and, consequently, are constantly replenished by differentiation of taste stem cells. Given the importance of establishing and maintaining appropriate connectivity between TRCs and their partner ganglion neurons (that is, ensuring that a labelled line from sweet TRCs connects to sweet neurons, bitter TRCs to bitter neurons, sour to sour, and so on), we examined how new connections are specified to retain fidelity of signal transmission. Here we show that bitter and sweet TRCs provide instructive signals to bitter and sweet target neurons via different guidance molecules (SEMA3A and SEMA7A). We demonstrate that targeted expression of SEMA3A or SEMA7A in different classes of TRCs produces peripheral taste systems with miswired sweet or bitter cells. Indeed, we engineered mice with bitter neurons that now responded to sweet tastants, sweet neurons that responded to bitter or sweet neurons responding to sour stimuli. Together, these results uncover the basic logic of the wiring of the taste system at the periphery, and illustrate how a labelled-line sensory circuit preserves signalling integrity despite rapid and stochastic turnover of receptor cells.

In mammals, taste buds typically contain 50-100 tightly packed taste receptor cells (TRCs) representing all five basic qualities: sweet, sour, bitter, salty and umami1,2. Notably, mature taste cells have life spans of only 5-20 days, and consequently, are constantly replenished by differentiation of taste stem cells3. Given the importance of establishing and maintaining appropriate connectivity between TRCs and their partner ganglion neurons (i.e. ensuring that a labeled line from sweet TRCs connects to sweet neurons, bitter TRCs to bitter neurons, sour to sour, etc.), we examined how new connections are specified to retain fidelity of signal transmission. Our results show that bitter and sweet TRCs provide instructive signals to bitter and sweet target neurons via different guidance molecules (Sema3A and Sema7A)4-6. Here, we demonstrate that targeted expression of Sema3A or Sema7A in different classes of TRCs produce peripheral taste systems with miswired sweet or bitter cells. Indeed, we engineered animals whereby bitter neurons now respond to sweet tastants, sweet neurons respond to bitter, or with sweet neurons responding to sour stimuli. Together, these results uncover the basic logic of the wiring of the taste system at the periphery, and illustrate how a labeled-line sensory circuit preserves signaling integrity despite rapid and stochastic turnover of receptor cells.

In cucurbits, phloem latex exudes from cut sieve tubes of the extrafascicular phloem (EFP), serving in defense against herbivores. We analyzed inducible defense mechanisms in the EFP of pumpkin (Cucurbita maxima) after leaf damage. As an early systemic response, wounding elicited transient accumulation of jasmonates and a decrease in exudation probably due to partial sieve tube occlusion by callose. The energy status of the EFP was enhanced as indicated by increased levels of ATP, phosphate, and intermediates of the citric acid cycle. Gas chromatography coupled to mass spectrometry also revealed that sucrose transport, gluconeogenesis/glycolysis, and amino acid metabolism were up-regulated after wounding. Combining ProteoMiner technology for the enrichment of low-abundance proteins with stable isotope-coded protein labeling, we identified 51 wound-regulated phloem proteins. Two Sucrose-Nonfermenting1-related protein kinases and a 32-kD 14-3-3 protein are candidate central regulators of stress metabolism in the EFP. Other proteins, such as the Silverleaf Whitefly-Induced Protein1, Mitogen Activated Protein Kinase6, and Heat Shock Protein81, have known defensive functions. Isotope-coded protein labeling and western-blot analyses indicated that Cyclophilin18 is a reliable marker for stress responses of the EFP. As a hint toward the induction of redox signaling, we have observed delayed oxidation-triggered polymerization of the major Phloem Protein1 (PP1) and PP2, which correlated with a decline in carbonylation of PP2. In sum, wounding triggered transient sieve tube occlusion, enhanced energy metabolism, and accumulation of defense-related proteins in the pumpkin EFP. The systemic wound response was mediated by jasmonate and redox signaling. PMID:23085839

Quantization of high dimensional Gaussian vector using permutation modulation with application to information reconciliation in continuous variable QKD

NASA Astrophysics Data System (ADS)

Daneshgaran, Fred; Mondin, Marina; Olia, Khashayar

This paper is focused on the problem of Information Reconciliation (IR) for continuous variable Quantum Key Distribution (QKD). The main problem is quantization and assignment of labels to the samples of the Gaussian variables observed at Alice and Bob. Trouble is that most of the samples, assuming that the Gaussian variable is zero mean which is de-facto the case, tend to have small magnitudes and are easily disturbed by noise. Transmission over longer and longer distances increases the losses corresponding to a lower effective Signal-to-Noise Ratio (SNR) exasperating the problem. Quantization over higher dimensions is advantageous since it allows for fractional bit per sample accuracy which may be needed at very low SNR conditions whereby the achievable secret key rate is significantly less than one bit per sample. In this paper, we propose to use Permutation Modulation (PM) for quantization of Gaussian vectors potentially containing thousands of samples. PM is applied to the magnitudes of the Gaussian samples and we explore the dependence of the sign error probability on the magnitude of the samples. At very low SNR, we may transmit the entire label of the PM code from Bob to Alice in Reverse Reconciliation (RR) over public channel. The side information extracted from this label can then be used by Alice to characterize the sign error probability of her individual samples. Forward Error Correction (FEC) coding can be used by Bob on each subset of samples with similar sign error probability to aid Alice in error correction. This can be done for different subsets of samples with similar sign error probabilities leading to an Unequal Error Protection (UEP) coding paradigm.

WHAT IS KNOWN AND OBJECTIVE: Physical bottle characteristics differ of brand name topical glaucoma medications and local generic equivalents. This study compares the bottle characteristics of international topical glaucoma brands versus local brands from the Kingdom of Saudi Arabia. METHODS: Data were collected on bottle drum volume, drop volume, bottle squeezability, bottle tip diameter, labels and instructions, cap color coding, and clarity of the drug label. Density-based calculations of drops in bottle volume were assessed using an analytic balance. Bottle tip diameter was measured using 0.05 mm Vernier calipers. A Likert scale-based questionnaire was used to evaluate the subjective opinions of patients on bottle squeezability, clarity of usage and storage instructions, and the consistency of the cap color coding. RESULTS: The volumes of international brands were statistically significantly higher than the local brands (P < 0.001). A number of drops per bottle and tip diameter were comparable between the international local brands. Cap color coding was inconsistent for international and local brands. Patients were dissatisfied with the label font size. Patients reported that the international and local brands were similar in terms of the ease of opening the bottle, instilling a drop, and the clarity of the instructions; but the local brands were subjectively easier to squeeze than international brands. WHAT IS NEW AND CONCLUSIONS: This is the first study to compare bottle characteristics of local Saudi Arabia brands with international brands. The bottle characteristics and patient feedback were similar between the local and international topical glaucoma medications. However, there were differences between the local and international brands in drug volume, bottle squeezability. Hence, patient compliance and drop dosage may differ based on the origin of manufacture. PMID:27994392

Contact-dependent intercellular transfer (codeIT) of cellular constituents can have functional consequences for recipient cells, such as enhanced survival and drug resistance. Pathogenic viruses, prions and bacteria can also utilize this mechanism to spread to adjacent cells and potentially evade immune detection. However, little is known about the molecular mechanism underlying this intercellular transfer process. Here, we present a novel microscopy-based screening method to identify regulators and cargo of codeIT. Single donor cells, carrying fluorescently labelled endocytic organelles or proteins, are co-cultured with excess acceptor cells. CodeIT is quantified by confocal microscopy and image analysis in 3D, preserving spatial information. An siRNA-based screening using this method revealed the involvement of several myosins and small GTPases as codeIT regulators. Our data indicates that cellular protrusions and tubular recycling endosomes are important for codeIT. We automated image acquisition and analysis to facilitate large-scale chemical and genetic screening efforts to identify key regulators of codeIT. PMID:26271723

The Framework Convention on Tobacco Control, a global health treaty ratified by over 175 countries, calls on countries to ensure that tobacco packages carry health warning labels (HWLs) describing the harmful effects of tobacco use. We assessed the extent of compliance with 14 countries' HWL requirements. Unique cigarette packs were purchased in 2013 using a systematic protocol in 12 distinct neighborhoods within three of the ten most populous cities in the 14 low- and middle-income countries with the greatest number (count) of smokers. HWL compliance codebooks were developed for each country based on the details of country-specific HWL requirements, with up to four common compliance indicators assessed for each country (location, size, label elements, text size). Packs (n=1859) were double coded for compliance. Compliance was examined by country and pack characteristics, including parent company and brand family. Overall, 72% of coded cigarette packs were compliant with all relevant compliance indicators, ranging from 17% in the Philippines to 94% in Mexico. Compliance was highest for location of the warning (ranging from 75%-100%) and lowest for warning size (ranging from 46%-99%). Compliance was higher for packs bought in high SES neighborhoods, and varied by parent company and brand family. This multi-country study found at least one pack in every country - and many packs in some countries - that were not compliant with key requirements for health warning labels in the country of purchase. Non-compliance may be exacerbating health disparities. Tobacco companies should be held accountable for complying with country HWL requirements. Copyright © 2016 The Authors.

Objective This study is the first to explore the impact of graphic cigarette labels with physical harm images on members of American Indian/Alaska Native (AI/AN) communities. The aim of this article is to investigate how AI/AN respond to particular graphic warning labels. Methods The parent study recruited smokers, at-risk smokers and non-smokers from three different age groups (youths aged 13–17 years, young adults aged 18–24 years and adults aged 25+ years) and five population subgroups with high smoking prevalence or smoking risk. Using nine graphic labels, this study collected participant data in the field via an iPad-administered survey and card sorting of graphic warning labels. This paper reports on findings for AI/AN participants. Results After viewing graphic warning labels, participants rated their likelihood of talking about smoking risks to friends, parents and siblings higher than their likelihood of talking to teachers and doctors. Further, this study found that certain labels (eg, the label of the toddler in the smoke cloud) made them think about their friends and family who smoke. Conclusions Given the influence of community social networks on health beliefs and attitudes, health communication using graphic warning labels could effect change in the smoking habits of AI/AN community members. Study findings suggest that graphic labels could serve as stimuli for conversations about the risks of smoking among AI/AN community members, and could be an important element of a peer-to-peer smoking cessation effort.

Graphic warning labels on plain cigarette packs: will they make a difference to adolescents?

Graphic warning labels and plain cigarette packaging are two initiatives developed to increase quit behaviour among smokers. Although a little is known about how adolescents interpret graphic warning labels, very few studies have examined how plain cigarette packaging would affect adolescents' perceptions of cigarette smoking and smoking behaviour. We explored how teens interpret and respond to graphic warning labels and the plain packaging of cigarettes, to assess the potential these strategies may offer in deterring smoking initiation. Twelve focus group interviews with a sample of 80 14-16 year old students from a diverse range of schools in Auckland, New Zealand were undertaken between June and August 2009. Textual analysis revealed that graphic warning labels may influence adolescents by reiterating a negative image of smokers. Graphic warning on a plain cigarette pack increased the attention paid to graphic warning labels and the overall perceptions of harm caused by cigarette smoking, and reduced the social appeal of cigarette smoking. This research offers evidence on how adolescents are appraising and interpreting graphic warning labels, and explores how dominant appraisals may affect the role graphic warning labels play in preventing smoking. Not only would plain cigarette packaging enhance the salience and impact of graphic warning labels, but it would potentially bolster the overall message that cigarette smoking is harmful. In the context of a comprehensive tobacco control programme, graphic warning labels on plain cigarette packaging present an explicit message about the risks (to health and image) associated with cigarette smoking.

2017-11-08

Using standardised terminology in acute care has encouraged consistency in patient care and the evaluation of outcomes. As such, the Nutrition Care Process (NCP) and Nutrition Care Process Terminology (NCPT) may assist dietitian nutritionists in the delivery of high quality nutrition care worldwide; however, limited research has been conducted examining the consistency and accuracy of its use. We aimed to examine the NCPT that dietitian nutritionists would use to formulate a diagnostic statement relating to refeeding syndrome (RFS). A multimethod action research approach was used, incorporating two projects. The first was a survey examining Australian dietitian nutritionists' (n = 195) opinions regarding NCPT use in cases of RFS. To establish if results were similar internationally, an interview was then conducted with 22 dietitian nutritionists working within 10 different countries. 'Imbalance of nutrients' was only identified as a correct code by 17% of respondents in project 1. No mention of this term was made in project 2. Also 86% of respondents incorrectly selected more than one diagnostic code. The majority of respondents (80%, n = 52/65) who incorrectly selected 'Malnutrition', without also selecting 'Imbalance of nutrients', selected 'reduce intake' as an intervention, suggesting some misunderstanding in the requirement for interrelated diagnoses, interventions and goals. Our findings demonstrate that there is limited accuracy and consistency in selecting nutritional diagnostic codes in relation to RFS. Respondents also demonstrated limited knowledge regarding appropriate application of the NCP and NCPT. Implementation practices may require further refinement, as accurate and consistent use is required to procure the benefits of standardised terminology. © 2017 Dietitians Association of Australia.

Interpersonal and systemic aspects of emotional abuse at work: the target's perspective.

PubMed

Keashly, L

2001-06-01

The most frequent form of workplace aggression is not physical, it is emotional and psychological in nature. Known by many names, emotional abuse at work is rapidly becoming recognized as pervasive and costly both in individual and organizational terms. Most of the research to date on emotional abuse at work has utilized survey and other quantitative methodologies in an effort to document the presence, prevalence, and impact of these behaviors. However, these methodologies are based on researchers' definitions and theories of what constitutes emotional abuse rather than on the meaning given to these experiences by the targets of these behaviors. A thorough understanding of this phenomenon requires a scholarly appreciation of the target's experience. Taking "feeling abused" as the criterion variable, this study examined target's experiences based on interviews with people who self-identifed as having experienced difficulties with a boss, coworker, or subordinate. The interpersonal aspects of emotional abuse focused on the nature of behaviors exhibited and the respondents' labeling of their experience. Consistent with elements of researchers' definitions, behaviors were defined as abusive when they were repetitive, resulted in injury or harm to target, and were experienced as a lack of recognition of the individual's integrity. Judgments of violation of standards of conduct and unsolicited nature of the behaviors were also related to respondents' experiences. Relative power differential was also an important element. However, contrary to researchers' definitions, actor intent was not central in defining the experience as abusive. The systemic aspect of emotional abuse was illustrated in the nature of organizational responding to concerns raised by respondents. These responses were of critical importance in respondents' labeling of their experiences as abusive. The focus on the meaning of the behaviors for the respondents provides an enriched picture of key definitional elements. Implications of the findings for future research are discussed.

Liquid chromatography-mass spectrometry (LC/MS) is a key technique in metabolomics. Since the efficient assignment of MS signals to true biological metabolites becomes feasible in combination with in vivo stable isotopic labelling, our aim was to provide a new software tool for this purpose. An algorithm and a program (MetExtract) have been developed to search for metabolites in in vivo labelled biological samples. The algorithm makes use of the chromatographic characteristics of the LC/MS data and detects MS peaks fulfilling the criteria of stable isotopic labelling. As a result of all calculations, the algorithm specifies a list of m/z values, the corresponding number of atoms of the labelling element (e.g. carbon) together with retention time and extracted adduct-, fragment- and polymer ions. Its function was evaluated using native (12)C- and uniformly (13)C-labelled standard substances. MetExtract is available free of charge and warranty at http://code.google.com/p/metextract/. Precompiled executables are available for Windows operating systems. Supplementary data are available at Bioinformatics online.

Inhibitory and modulatory inputs to the vocal central pattern generator of a teleost fish

2018-01-01

Abstract Vocalization is a behavioral feature that is shared among multiple vertebrate lineages, including fish. The temporal patterning of vocal communication signals is set, in part, by central pattern generators (CPGs). Toadfishes are well‐established models for CPG coding of vocalization at the hindbrain level. The vocal CPG comprises three topographically separate nuclei: pre‐pacemaker, pacemaker, motor. While the connectivity between these nuclei is well understood, their neurochemical profile remains largely unexplored. The highly vocal Gulf toadfish, Opsanus beta, has been the subject of previous behavioral, neuroanatomical and neurophysiological studies. Combining transneuronal neurobiotin‐labeling with immunohistochemistry, we map the distribution of inhibitory neurotransmitters and neuromodulators along with gap junctions in the vocal CPG of this species. Dense GABAergic and glycinergic label is found throughout the CPG, with labeled somata immediately adjacent to or within CPG nuclei, including a distinct subset of pacemaker neurons co‐labeled with neurobiotin and glycine. Neurobiotin‐labeled motor and pacemaker neurons are densely co‐labeled with the gap junction protein connexin 35/36, supporting the hypothesis that transneuronal neurobiotin‐labeling occurs, at least in part, via gap junction coupling. Serotonergic and catecholaminergic label is also robust within the entire vocal CPG, with additional cholinergic label in pacemaker and prepacemaker nuclei. Likely sources of these putative modulatory inputs are neurons within or immediately adjacent to vocal CPG neurons. Together with prior neurophysiological investigations, the results reveal potential mechanisms for generating multiple classes of social context‐dependent vocalizations with widely divergent temporal and spectral properties.

2011-02-23

Health care utilization databases have been increasingly used for studies of rheumatoid arthritis (RA). However, the accuracy of RA diagnoses in these data has been inconsistent. Using medical records and a standardized abstraction form, we examined the positive predictive value (PPV) of several algorithms to define RA diagnosis using claims data: A) at least two visits coded for RA (ICD-9, 714); B) at least three visits coded for RA; and C) at least two visits to a rheumatologist for RA. We also calculated the PPVs for the subgroups identified by these algorithms combined with pharmacy claims data for at least one disease-modifying anti-rheumatic drug (DMARD) prescription. We invited 9,482 Medicare beneficiaries with pharmacy benefits in Pennsylvania to participate; 2% responded and consented for review of their medical records. There was no difference in characteristics between respondents and non-respondents. Using 'RA diagnosis per rheumatologists' as the gold standard, the PPVs were 55.7% for at least two claims coded for RA, 65.5% for at least three claims for RA, and 66.7% for at least two rheumatology claims for RA. The PPVs of these algorithms in patients with at least one DMARD prescription increased to 86.2%-88.9%. When fulfillment of 4 or more of the ACR RA criteria was used as the gold standard, the PPVs of the algorithms combined with at least one DMARD prescriptions were 55.6%-60.7%. To accurately identify RA patients in health care utilization databases, algorithms that include both diagnosis codes and DMARD prescriptions are recommended.

Urban planners have suggested that built environment characteristics can support active travel (walking and cycling) and reduce sedentary behavior. This study assessed whether engagement in active travel is associated with neighborhood walkability measured for zip codes in New York City. Data were analyzed on engagement in active travel and the frequency of walking or biking ten blocks or more in the past month, from 8,064 respondents to the New York City 2003 Community Health Survey (CHS). A neighborhood walkability scale that measures: residential, intersection, and subway stop density; land use mix; and the ratio of retail building floor area to retail land area was calculated for each zip code. Data were analyzed using zero-inflated negative binomial regression incorporating survey sample weights and adjusting for respondents' sociodemographic characteristics. Overall, 44 % of respondents reported no episodes of active travel and among those who reported any episode, the mean number was 43.2 episodes per month. Comparing the 75th to the 25th percentile of zip code walkability, the odds ratio for reporting zero episodes of active travel was 0.71 (95 % CI 0.61, 0.83) and the exponentiated beta coefficient for the count of episodes of active travel was 1.13 (95 % CI 1.06, 1.21). Associations between lower walkability and reporting zero episodes of active travel were significantly stronger for non-Hispanic Whites as compared to non-Hispanic Blacks and to Hispanics and for those living in higher income zip codes. The results suggest that neighborhood walkability is associated with higher engagement in active travel.

Recently implemented New York State policy allows police and fire to administer intranasal naloxone when responding to opioid overdoses. This work describes the geographic distribution of naloxone administration (NlxnA) by police and fire when responding to opioid overdoses in Erie County, NY, an area of approximately 920,000 people including the City of Buffalo. Data are from opioid overdose reports (N = 800) filed with the Erie County Department of Health (July 2014-June 2016) by police/fire and include the overdose ZIP code, reported drug(s) used, and NlxnA. ZIP code data were geocoded and mapped to examine spatial patterns of NlxnA. The highest NlxnA rates (range: 0.01-84.3 per 10,000 population) were concentrated within the city and first-ring suburbs. Within 3 min 27.3% responded to NlxnA and 81.6% survived the overdose. The average individual was male (70.3%) and 31.4 years old (SD = 10.3). Further work is needed to better understand NlxnA and overdose, including exploring how the neighborhood environment creates a context for drug use, and how this context influences naloxone use and overdose experiences.

ADESSA: A Real-Time Decision Support Service for Delivery of Semantically Coded Adverse Drug Event Data

Duke, Jon D.; Friedlin, Jeff

2010-01-01

Evaluating medications for potential adverse events is a time-consuming process, typically involving manual lookup of information by physicians. This process can be expedited by CDS systems that support dynamic retrieval and filtering of adverse drug events (ADE’s), but such systems require a source of semantically-coded ADE data. We created a two-component system that addresses this need. First we created a natural language processing application which extracts adverse events from Structured Product Labels and generates a standardized ADE knowledge base. We then built a decision support service that consumes a Continuity of Care Document and returns a list of patient-specific ADE’s. Our database currently contains 534,125 ADE’s from 5602 product labels. An NLP evaluation of 9529 ADE’s showed recall of 93% and precision of 95%. On a trial set of 30 CCD’s, the system provided adverse event data for 88% of drugs and returned these results in an average of 620ms. PMID:21346964

Unsupervised Transfer Learning via Multi-Scale Convolutional Sparse Coding for Biomedical Applications

2017-01-01

The capabilities of (I) learning transferable knowledge across domains; and (II) fine-tuning the pre-learned base knowledge towards tasks with considerably smaller data scale are extremely important. Many of the existing transfer learning techniques are supervised approaches, among which deep learning has the demonstrated power of learning domain transferrable knowledge with large scale network trained on massive amounts of labeled data. However, in many biomedical tasks, both the data and the corresponding label can be very limited, where the unsupervised transfer learning capability is urgently needed. In this paper, we proposed a novel multi-scale convolutional sparse coding (MSCSC) method, that (I) automatically learns filter banks at different scales in a joint fashion with enforced scale-specificity of learned patterns; and (II) provides an unsupervised solution for learning transferable base knowledge and fine-tuning it towards target tasks. Extensive experimental evaluation of MSCSC demonstrates the effectiveness of the proposed MSCSC in both regular and transfer learning tasks in various biomedical domains. PMID:28129148

Aggregating and Predicting Sequence Labels from Crowd Annotations

2017-01-01

Despite sequences being core to NLP, scant work has considered how to handle noisy sequence labels from multiple annotators for the same text. Given such annotations, we consider two complementary tasks: (1) aggregating sequential crowd labels to infer a best single set of consensus annotations; and (2) using crowd annotations as training data for a model that can predict sequences in unannotated text. For aggregation, we propose a novel Hidden Markov Model variant. To predict sequences in unannotated text, we propose a neural approach using Long Short Term Memory. We evaluate a suite of methods across two different applications and text genres: Named-Entity Recognition in news articles and Information Extraction from biomedical abstracts. Results show improvement over strong baselines. Our source code and data are available online1. PMID:29093611

Automatic ground control point recognition with parallel associative memory

Al-Tahir, Raid; Toth, Charles K.; Schenck, Anton F.

1990-01-01

The basic principle of the associative memory is to match the unknown input pattern against a stored training set, and responding with the 'closest match' and the corresponding label. Generally, an associative memory system requires two preparatory steps: selecting attributes of the pattern class, and training the system by associating patterns with labels. Experimental results gained from using Parallel Associative Memory are presented. The primary concern is an automatic search for ground control points in aerial photographs. Synthetic patterns are tested followed by real data. The results are encouraging as a relatively high level of correct matches is reached.

Stroke Severity Affects Timing: Time From Stroke Code Activation to Initial Imaging is Longer in Patients With Milder Strokes.

Optimizing the time it takes to get a potential stroke patient to imaging is essential in a rapid stroke response. At our hospital, door-to-imaging time is comprised of 2 time periods: the time before a stroke is recognized, followed by the period after the stroke code is called during which the stroke team assesses and brings the patient to the computed tomography scanner. To control for delays due to triage, we isolated the time period after a potential stroke has been recognized, as few studies have examined the biases of stroke code responders. This "code-to-imaging time" (CIT) encompassed the time from stroke code activation to initial imaging, and we hypothesized that perception of stroke severity would affect how quickly stroke code responders act. In consecutively admitted ischemic stroke patients at The Mount Sinai Hospital emergency department, we tested associations between National Institutes of Health Stroke Scale scores (NIHSS), continuously and at different cutoffs, and CIT using spline regression, t tests for univariate analysis, and multivariable linear regression adjusting for age, sex, and race/ethnicity. In our study population, mean CIT was 26 minutes, and mean presentation NIHSS was 8. In univariate and multivariate analyses comparing CIT between mild and severe strokes, stroke scale scores <4 were associated with longer response times. Milder strokes are associated with a longer CIT with a threshold effect at a NIHSS of 4.

Metabolically Generated Stable Isotope-Labeled Deoxynucleoside Code for Tracing DNA N6-Methyladenine in Human Cells.

2017-06-06

DNA N 6 -methyl-2'-deoxyadenosine (6mdA) is an epigenetic modification in both eukaryotes and bacteria. Here we exploited stable isotope-labeled deoxynucleoside [ 15 N 5 ]-2'-deoxyadenosine ([ 15 N 5 ]-dA) as an initiation tracer and for the first time developed a metabolically differential tracing code for monitoring DNA 6mdA in human cells. We demonstrate that the initiation tracer [ 15 N 5 ]-dA undergoes a specific and efficient adenine deamination reaction leading to the loss the exocyclic amine 15 N, and further utilizes the purine salvage pathway to generate mainly both [ 15 N 4 ]-dA and [ 15 N 4 ]-2'-deoxyguanosine ([ 15 N 4 ]-dG) in mammalian genomes. However, [ 15 N 5 ]-dA is largely retained in the genomes of mycoplasmas, which are often found in cultured cells and experimental animals. Consequently, the methylation of dA generates 6mdA with a consistent coding pattern, with a predominance of [ 15 N 4 ]-6mdA. Therefore, mammalian DNA 6mdA can be potentially discriminated from that generated by infecting mycoplasmas. Collectively, we show a promising approach for identification of authentic DNA 6mdA in human cells and determine if the human cells are contaminated with mycoplasmas.

Consumer choice: Linking consumer intentions to actual purchase of GM labeled food products.

PubMed

Sleenhoff, Susanne; Osseweijer, Patricia

2013-01-01

With a mandatory labeling scheme for GM food in Europe since 2004 measuring actual consumer choice in practice has become possible. Anticipating Europeans negative attitude toward GM food, the labeling was enforced to allow consumers to make an informed choice. We studied consumers actual purchase behavior of GM food products and compared this with their attitude and behavioral intention for buying GM food. We found that despite a majority of consumers voicing a negative attitude toward GM food over 50% of our European respondents stated that they did not actively avoid the purchase of GM food and 6% actually purchased one of the few available GM labeled food products in the period between September 2006 and October 2007. Our results imply that a voiced negative attitude of consumers in responses to questionnaires about their intentions is not a reliable guide for what they actually do in supermarkets. We conclude that the assumption of a negative attitude with regard to GM food is at least in part construed.

Survey to investigate pet ownership and attitudes to pet care in metropolitan Chicago dog and/or cat owners.

2014-08-01

The aims of this descriptive cross-sectional study were to investigate dog and cat acquisition and attitudes toward pet care among residents of the Chicago area (zip codes 60600-60660); to compare data obtained from owners of shelter-acquired pets with those of residents who acquired their pets from other sources; to compare data from dog owners with cat owners; and to compare pet health practices among the respondents of different zip code income groups. In-person surveys administered at five pet store locations collected data from 529 respondents, representing 582 dogs and 402 cats owned or continuously cared for in the past 3 years. Median household income data for represented zip codes was also obtained. Shelters were the most common source of cats (p<0.01) and were the second most common source of dogs. Cats were more likely to have been acquired as strays, while dogs were more likely to have been acquired from friends/family/neighbors, pet stores, breeders or rescue organizations and to be kept as outdoor-only pets (p<0.01). More cats were kept per household than dogs (dogs mean=1.32/household; cats mean=1.78/household; p<0.01). Pet owners were most commonly 'very likely' (5 on a 1-5/5 Likert scale) to administer all hypothetical treatments discussed, although cat owners were less likely to spend time training their pet (p=0.05). Cat owners were less likely to have taken their pet to a veterinarian for vaccinations or annual physical exams (p<0.01). Shelter-acquired cats were significantly more likely to have been taken by their owners to the veterinarian for annual exams (p=0.05) than cats obtained as strays. Owners of shelter-acquired pets were at least as willing as other respondents to administer hypothetical treatments and pay ≥$1000 for veterinary treatment. Respondents from site #3 lived in zip codes that had relatively lower median household incomes (p<0.01) and were less likely to spend ≥$1000 on their pets than those at the four other sites (p<0.01). Over 90% of pet owners from all acquisition categories expressed very high levels of attachment (≥8-10/10 on a Likert scale), except for owners of cats acquired as strays (84.9%) or from the 'other' category (75.0%). Survey respondents commonly acquired their pets from shelters and those who did were at least as willing to pay for and provide veterinary care as respondents who owned pets acquired from other sources. The data collected provides a snapshot of the attitudes of survey respondents in the Chicago area toward pet acquisition and care. Copyright © 2014 Elsevier B.V. All rights reserved.

Fan, Linyu; Liao, Jianwei; Zuo, Junsen; Zhang, Kebo; Li, Chao; Xiong, Hailing

2018-07-01

This paper presents a new version Java code for the three-dimensional simulation of Cluster-Cluster Aggregation (CCA) model to replace the previous version. Many redundant traverses of clusters-list in the program were totally avoided, so that the consumed simulation time is significantly reduced. In order to show the aggregation process in a more intuitive way, we have labeled different clusters with varied colors. Besides, a new function is added for outputting the particle's coordinates of aggregates in file to benefit coupling our model with other models.

To assess the effects of aripiprazole once-monthly 400 mg (AOM 400) on clinical symptoms and global improvement in schizophrenia after switching from an oral antipsychotic. In a multicenter, open-label, mirror-image, naturalistic study in patients with schizophrenia (>1 year, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] criteria), changes in efficacy measures were assessed during prospective treatment (6 months) with AOM 400 after switching from standard-of-care oral antipsychotics. During prospective treatment, patients were cross-titrated to oral aripiprazole monotherapy (1-4) weeks followed by open-label AOM 400 (24 weeks). Mean change from baseline of the open-label AOM 400 phase in Positive and Negative Syndrome Scale (PANSS) scores (total, positive and negative subscales) and Clinical Global Impression-Severity (CGI-S) scores; mean CGI-Improvement (CGI-I) score; and proportion of responders (≥30% decrease from baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much improved]) were assessed. PANSS and CGI-S scores improved from baseline (P<0.0001) and CGI-I demonstrated improvement at all time points. By the end of the study, 49.0% of patients were PANSS or CGI-I responders. In a community setting, patients with schizophrenia who were stabilized at baseline and switched to AOM 400 from oral antipsychotics showed clear improvements in clinical symptoms.

Heterosexual Men's Ratings of Sexual Attractiveness of Adolescent Girls: A Cross-Cultural Analysis.

PubMed

Bennett, Paul; Lowe, Rob; Petrova, Hristina

2015-11-01

Following an identical procedure to the one we previously reported (O'Donnell, Lowe, Brotherton, & Bennett, 2014), we examined ratings of sexual attraction to photographs of (the same) adolescent girls (Tanner stages 3-4) labelled as either 14-15 years or 16-17 years old, women, and men. Ratings were made by Bulgarian heterosexual men by pressing buttons on a response box which recorded the ratings made and the time in milliseconds taken to respond. Despite the age of sexual consent in Bulgaria being 14 years, the pattern of findings did not differ from those found in the UK, where the age of consent is 16 years. That is, mean ratings of the sexual attractiveness of the girls labelled as younger were lower than those of the (same) girls labelled as older, and those of the women. In addition, correlations revealed significantly longer responding times when younger girls (and men) were rated as more highly sexually attractive. These associations were reversed in response to the photographs of women. We take these findings to indicate an inhibitory effect arising from generalized sexual norms relating to the inappropriateness of sexual attraction to young girls; the greater the attraction, the higher the inhibition. This second replication of our initial findings suggests a robust effect that may be of benefit in exploration of pedophile or sex offender groups.

Perception of the minority's collective identity and voting behavior: the case of the Palestinians in Israel.

PubMed

Suleiman, Ramzi

2002-12-01

The author investigated how Palestinian (n = 130) and Jewish (n = 153) Israeli university students perceived the collective identity of the Palestinian minority in Israel. The Palestinian and Jewish respondents perceived the "identity space" of the minority as linear, or bipolar, with 1 pole defined by the national (Palestinian) identity and the other defined by the civic (Israeli) label. The Palestinian respondents defined their collective identity in national (Palestinian, Arab) and integrative (Israeli-Palestinian) terms; the Jewish respondents perceived the minority's identity as integrative (Israeli-Palestinian). Different political outlooks among Palestinian respondents were related to their identification with the civic (Israeli) identity but not to their identification with the national (Palestinian) identity. In contrast, different political outlooks among Jewish respondents were related to their inclusion, or exclusion, of the national (Palestinian) component in their definition of the minority's identity. Implications of the results are discussed in terms of a minority acculturation model (J. Berry, J. Trimble, & E. Olmedo, 1986).

Abstract Objective  To clarify preferred labels for people receiving health care. Background  The proper label to describe people receiving care has evoked considerable debate among providers and bio‐ethicists, but there is little evidence as to the preferences of the people involved. Design  We analysed dictionary definitions as to the derivation and connotations of such potential labels as: patient, client, customer, consumer, partner and survivor. We then surveyed outpatients from four clinical populations in Ontario, Canada about their feelings about these labels. Setting and participants  People from breast cancer (n = 202), prostate disease (n = 202) and fracture (n = 202) clinics in an urban Canadian teaching hospital (Sharpe study), and people with HIV/AIDS at 10 specialty care clinics and three primary care practices affiliated with the HIV Ontario Observational Database (n = 431). Variables and outcome measures  The survey instruments included questions about opinion of label, role in treatment decision‐making (the Problem Solving Decision Making scale), trust, use of information and health status. Results  Our respondents moderately liked the label ‘patient’. The other alternatives evoked moderate to strong dislike. Conclusions  Many alternatives to ‘patient’ incorporate assumptions (e.g. a market relationship) which care recipients may also find objectionable. People who are receiving care find the label ‘patient’ much less objectionable than the alternatives that have been suggested. PMID:16266422

To identify different segments of U.S. consumers based on food choices, exercise patterns, and desire for restaurant calorie labeling. Using a stratified (by region) random sample of the U.S. population, trained interviewers collected data for this cross-sectional study through telephone surveys. Center for Rural Studies U.S. national health survey. The final sample included 580 responses (22% response rate); data were weighted to be representative of age and gender characteristics of the U.S. population. Self-reported behaviors related to food choices, exercise patterns, desire for calorie information in restaurants, and sample demographics. Clusters were identified using Schwartz Bayesian criteria. Impacts of demographic characteristics on cluster membership were analyzed using bivariate tests of association and multinomial logit regression. Cluster analysis revealed three clusters based on respondents' food choices, activity levels, and desire for restaurant labeling. Two clusters, comprising three quarters of the sample, desired calorie labeling in restaurants. The remaining cluster opposed restaurant labeling. Demographic variables significantly predicting cluster membership included region of residence (p < .10), income (p < .05), gender (p < .01), and age (p < .10). Though limited by a low response and potential self-reporting bias in the phone survey, this study suggests that several groups are likely to benefit from restaurant calorie labeling. Specific demographic clusters could be targeted through labeling initiatives.

Aim To identify experience with and attitudes towards paediatric off-label prescribing in primary care. Method A prospective questionnaire survey was sent to a sample of Scottish primary care practices (346 doctors in 80 general practices located throughout Scotland). Results Two hundred and two (58%) completed questionnaires were returned. Over 70% of GPs admitted to being familiar with the concept, and 40% to knowingly prescribing off-label. The most important sources of paediatric prescribing information were the British National Formulary (81%), personal experience (71%) and previous prescription notes (45%). The most common reason given by GPs for off-label prescribing was prescribing for a younger age than recommended, although prescribing data confirm that age is the least important and dose the most important reason for such prescribing. When asked to comment upon different causes for off-label prescribing, 80% of respondents expressed appropriate awareness of and concern for the described scenarios. Over 97% of GPs ranked development of paediatric formulations and clearer dosage information more highly than clinical trials as a means to reducing off-label prescribing. Conclusions Despite high levels of off-label prescribing in primary care in the UK, the majority of GPs claimed to be familiar with the concept, although less than half were aware of this common practice. A clear disparity between perceived and actual reasons for off-label prescribing was noted, possibly due to a reliance on personal experience, colleague experience or previous patient prescription notes as a guide to prescribing.

Background The Nutrition Facts label can facilitate healthy dietary practices. There is a dearth of research on Latinos’ utilization and comprehension of the Nutrition Facts label. Objective To measure Nutrition Facts label use and comprehension and to identify their correlates among Latinos in East Los Angeles. Design Cross-sectional interviewer-administered survey using a computer assisted personal interview (CAPI) software conducted in either English or Spanish in the participant’s home. Participants/Setting Eligibility criteria were: living in a household within the block clusters identified, being age 18 or over, speaking English or Spanish, identifying as Latino and as the household’s main food purchaser and preparer. Analyses were based on 269 eligible respondents. Statistical analyses performed Chi-square test and multivariate logistic regression analysis assessed the association between the main outcomes and demographics. Multiple imputation addressed missing data. Results Sixty percent reported using the label; only 13% showed adequate comprehension of the label. Utilization was associated with being female, speaking Spanish and being below the poverty line. Comprehension was associated with younger age, not being married, and higher education. Utilization was not associated with comprehension. Conclusions Latinos who are using the Nutrition Facts label are not correctly interpreting the available information. Targeted education is needed to improve Nutrition Facts label use and comprehension, to directly improve diet, particularly among males, older Latinos, and those with less than a high school education.

2015-01-01

In 2009, the U.S. Food and Drug Administration was required to mandate that graphic health warning labels be placed on cigarette packages and advertisements. To assess public support in the U.S. for graphic health warning labels from 2007 to 2012. Data from 17,498 respondents from 13 waves of the National Adult Tobacco Survey, a list-assisted random-digit-dial survey, were used. Overall support for graphic health warning labels, as well as support by smoking status, and by sociodemographics and smoker characteristics are estimated. Analyses were conducted in 2014. Since 2007, a majority of the public overall has been in favor of labels. Support increased significantly among the public overall and among non-smokers from 2007 through 2009 (p<0.001), after which it remained flat. Among smokers, support levels increased from 2007 through 2011 (p<0.001), but decreased significantly from 2011 through 2012 (p<0.001). Support was high regardless of smoking status, although among smokers, support varied by level of smoking, interest in quitting, and whether labels were seen as an important reason to quit. Support varied by sociodemographic characteristics, particularly among smokers. Younger, less-affluent, and less-educated smokers supported labels at higher levels than their counterparts. A majority of U.S. residents support graphic health warning labels for cigarette packs, though support among smokers declined after 2011. Copyright © 2015 American Journal of Preventive Medicine.

Graphical tobacco product labelling is a prominent source of health information and has an important position among tobacco control initiatives. However, little is known about its effectiveness among adolescents. With this above in mind, we aimed to research into how adolescents perceive the proposed EU graphic tobacco product warning labels as an effective means of preventing smoking initiation in comparison to the current EU text-only warning labels. Five hundred seventy four adolescents (13-18, 54% male) from Greece were privately interviewed, with the use of a digital questionnaire and randomly shown seven existing EU text-only and proposed EU graphic warning labels. Non-smoking respondents were asked to compare and rate the warnings effectiveness in regard to preventing them from smoking on a 1-5 Likert type scale. Irrespective of the warning category shown, on all occasions, non-smoking adolescents rated the suggested EU graphic labels as more effective in preventing them from smoking in comparison to the existing EU text-only warnings. Controlling for gender, age, current smoking status and number of cigarettes smoked per month, younger adolescents were found to opt for graphic warnings more often, and also perceive graphic warning labels as a more effective means of preventing them from smoking, in comparison to their elder peers (P < 0.001). The proposed EU graphic warning labels may play an important role in preventing of smoking initiation during the crucial years of early adolescence when smoking experimentation and early addiction usually take place.

Unsupervised Deep Hashing With Pseudo Labels for Scalable Image Retrieval.

PubMed

Zhang, Haofeng; Liu, Li; Long, Yang; Shao, Ling

2018-04-01

In order to achieve efficient similarity searching, hash functions are designed to encode images into low-dimensional binary codes with the constraint that similar features will have a short distance in the projected Hamming space. Recently, deep learning-based methods have become more popular, and outperform traditional non-deep methods. However, without label information, most state-of-the-art unsupervised deep hashing (DH) algorithms suffer from severe performance degradation for unsupervised scenarios. One of the main reasons is that the ad-hoc encoding process cannot properly capture the visual feature distribution. In this paper, we propose a novel unsupervised framework that has two main contributions: 1) we convert the unsupervised DH model into supervised by discovering pseudo labels; 2) the framework unifies likelihood maximization, mutual information maximization, and quantization error minimization so that the pseudo labels can maximumly preserve the distribution of visual features. Extensive experiments on three popular data sets demonstrate the advantages of the proposed method, which leads to significant performance improvement over the state-of-the-art unsupervised hashing algorithms.

Cross-label Suppression: a Discriminative and Fast Dictionary Learning with Group Regularization.

PubMed

Wang, Xiudong; Gu, Yuantao

2017-05-10

This paper addresses image classification through learning a compact and discriminative dictionary efficiently. Given a structured dictionary with each atom (columns in the dictionary matrix) related to some label, we propose crosslabel suppression constraint to enlarge the difference among representations for different classes. Meanwhile, we introduce group regularization to enforce representations to preserve label properties of original samples, meaning the representations for the same class are encouraged to be similar. Upon the cross-label suppression, we don't resort to frequently-used `0-norm or `1- norm for coding, and obtain computational efficiency without losing the discriminative power for categorization. Moreover, two simple classification schemes are also developed to take full advantage of the learnt dictionary. Extensive experiments on six data sets including face recognition, object categorization, scene classification, texture recognition and sport action categorization are conducted, and the results show that the proposed approach can outperform lots of recently presented dictionary algorithms on both recognition accuracy and computational efficiency.

In the field of assisted reproductive technology (ART), medical accidents can result in serious legal and social consequences. This study was conducted to develop a security system (called IVF-guardian; IG) that could prevent mismatching or mix-ups in ART. A software program was developed in collaboration with outside computer programmers. A quick response (QR) code was used to identify the patients, gametes and embryos in a format that was printed on a label. There was a possibility that embryo development could be affected by volatile organic components (VOC) in the printing material and adhesive material in the label paper. Further, LED light was used as the light source to recognize the QR code. Using mouse embryos, the effects of the label paper and LED light were examined. The stability of IG was assessed when applied in clinical practice after developing the system. A total of 104 cycles formed the study group, and 82 cycles (from patients who did not want to use IG because of safety concerns and lack of confidence in the security system) to which IG was not applied comprised the control group. Many of the label paper samples were toxic to mouse embryo development. We selected a particular label paper (P touch label) that did not affect mouse embryo development. The LED lights were non-toxic to the development of the mouse embryos under any experimental conditions. There were no differences in the clinical pregnancy rates between the IG-applied group and the control group (40/104 = 38.5 % and 30/82 = 36.6 %, respectively). The application of IG in clinical practice did not affect human embryo development or clinical outcomes. The use of IG reduces the misspelling of patient names. Using IG, there was a disadvantage in that each treatment step became more complicated, but the medical staff improved and became sufficiently confident in ART to offset this disadvantage. Patients who received treatment using the IG system also went through a somewhat tedious process, but there were no complaints. These patients gained further confidence in the practitioners over the course of treatment.

The objective of this study was to investigate vehicle factors associated with child restraint tether use and misuse in pickup trucks and evaluate 4 labeling interventions designed to educate consumers on proper tether use. Volunteer testing was performed with 24 subjects and 4 different pickup trucks. Each subject performed 8 child restraint installations among the 4 pickups using 2 forward-facing restraints: a Britax Marathon G4.1 and an Evenflo Triumph. Vehicles were selected to represent 4 different implementations of tether anchors among pickups: plastic loop routers (Chevrolet Silverado), webbing routers (Ram), back wall anchors (Nissan Frontier), and webbing routers plus metal anchors (Toyota Tundra). Interventions included a diagram label, Quick Response (QR) Code linked to video instruction, coordinating text label, and contrasting text tag. Subjects used the child restraint tether in 93% of trials. However, tether use was completely correct in only 9% of trials. An installation was considered functional if the subject attached the tether to a tether anchor and had a tight installation (ignoring routing and head restraint position); 28% of subjects achieved a functional installation. The most common installation error was attaching the tether hook to the anchor/router directly behind the child restraint (near the top of the seatback) rather than placing the tether through the router and attaching it to the anchor in the adjacent seating position. The Nissan Frontier, with the anchor located on the back wall of the cab, had the highest rate of correct installations but also had the highest rate of attaching the tether to components other than the tether anchor (seat adjustor, child restraint storage hook, around head restraint). None of the labeling interventions had a significant effect on correct installation; not a single subject scanned the QR Code to access the video instruction. Subjects with the most successful installations spent extensive time reviewing the vehicle manuals. Current implementations of tether anchors among pickup trucks are not intuitive for child restraint installations, and alternate designs should be explored. Several different labeling interventions were ineffective at achieving correct tether use in pickup trucks.

Identification of treatment responders based on multiple longitudinal outcomes with applications to multiple sclerosis patients.

2017-05-30

Identification of treatment responders is a challenge in comparative studies where treatment efficacy is measured by multiple longitudinally collected continuous and count outcomes. Existing procedures often identify responders on the basis of only a single outcome. We propose a novel multiple longitudinal outcome mixture model that assumes that, conditionally on a cluster label, each longitudinal outcome is from a generalized linear mixed effect model. We utilize a Monte Carlo expectation-maximization algorithm to obtain the maximum likelihood estimates of our high-dimensional model and classify patients according to their estimated posterior probability of being a responder. We demonstrate the flexibility of our novel procedure on two multiple sclerosis clinical trial datasets with distinct data structures. Our simulation study shows that incorporating multiple outcomes improves the responder identification performance; this can occur even if some of the outcomes are ineffective. Our general procedure facilitates the identification of responders who are comprehensively defined by multiple outcomes from various distributions. Copyright © 2017 John Wiley & Sons, Ltd.

2015-11-01

To follow up on a previous study that examined how the mandated displaying of calorie information on menu boards in fast-food restaurants in New York City influenced consumers' behavior, we analyzed itemized cash register receipts and survey responses from 7,699 consumers at four fast-food chains. Using a difference-in-differences study design, we found that consumers exposed to menu labeling immediately after the mandate took effect in 2008 and at three points in 2013-14 reported seeing and using the information more often than their counterparts at fast-food restaurants without menu labeling. In each successive period of data collection, the percentage of respondents noticing and using the information declined, while remaining above the prelabeling baseline. There were no statistically significant changes over time in levels of calories or other nutrients purchased or in the frequency of visits to fast-food restaurants. Menu labeling at fast-food chain restaurants, which the Affordable Care Act requires to be implemented nationwide in 2016, remains an unproven strategy for improving the nutritional quality of consumer food choices at the population level. Additional policy efforts that go beyond labeling and possibly alter labeling to increase its impact must be considered. Project HOPE—The People-to-People Health Foundation, Inc.

Evidence that ganglion cells react to retinal detachment.

Coblentz, Francie E; Radeke, Monte J; Lewis, Geoffrey P; Fisher, Steven K

2003-03-01

Growth associated protein 43 (GAP 43) is involved in synapse formation and it is expressed in the retina in a very specific pattern. Although GAP 43 is downregulated at the time of synapse formation, it can be re-expressed following injury such as axotomy or ischemia. Because of this we sought to characterize the expression of GAP 43 after retinal detachment (RD). Immunoblot, immunocytochemical and quantitative polymerase chain reaction (QPCR) techniques were used to assess the level of GAP 43 expression after experimental RD. GAP 43 was localized to three sublaminae of the inner plexiform layer of the normal retina. GAP 43 became upregulated in a subset of retinal ganglion cells following at least 7 days of RD. By immunoblot GAP 43 could be detected by 3 days. QPCR shows the upregulation of GAP 43 message by 6hr of detachment. To further characterize changes in ganglion cells, we used an antibody to neurofilament 70 and 200kDa (NF) proteins. Anti-NF labels horizontal cells, ganglion cell dendrites in the inner plexiform layer, and ganglion cell axons (fasicles) in the normal retina. Following detachment it is upregulated in horizontal cells and ganglion cells. When detached retina was double labelled with anti-GAP 43 and anti-NF, some cells were labelled with both markers, while others labelled with only one. We have previously shown that second order neurons respond to detachment; here we show that third order neurons are responding as well. Cellular remodelling of this type in response to detachment may explain the slow recovery of vision that often occurs after reattachment, or those changes that are often assumed to be permanent.

Noisy breathing is a common presenting symptom in children. The purpose of this study is to (a) assess parental ability to label wheeze, (b) compare the ability of parents of children with and without asthma to label wheeze and (c) determine factors affecting parental ability to label wheeze correctly. This cross-sectional study in a tertiary hospital in Kuala Lumpur, Malaysia involved parents of children with asthma. Parents of children without asthma were the control group. Eleven validated video clips showing wheeze, stridor, transmitted noises, snoring or normal breathing were shown to the parents. Parents were asked, in English or Malay, "What do you call the sound this child is making?" and "Where do you think the sound is coming from?" Two hundred parents participated in this study: 100 had children with asthma while 100 did not. Most (71.5 %) answered in Malay. Only 38.5 % of parents correctly labelled wheeze. Parents were significantly better at locating than labelling wheeze (OR 2.4, 95 % CI 1.64-3.73). Parents with asthmatic children were not better at labelling wheeze than those without asthma (OR1.04, 95 % CI 0.59-1.84). Answering in English (OR 3.4, 95 % CI 1.69-7.14) and having older children with asthma (OR 9.09, 95 % CI 3.13-26.32) were associated with correct labelling of wheeze. Other sounds were mislabelled as wheeze by 16.5 % of respondents. Parental labelling of wheeze was inaccurate especially in the Malay language. Parents were better at identifying the origin of wheeze rather than labelling it. Physicians should be wary about parental reporting of wheeze as it may be inaccurate.

This study is the first to explore the impact of graphic cigarette labels with physical harm images on members of American Indian/Alaska Native (AI/AN) communities. The aim of this article is to investigate how AI/AN respond to particular graphic warning labels. The parent study recruited smokers, at-risk smokers and non-smokers from three different age groups (youths aged 13-17 years, young adults aged 18-24 years and adults aged 25+ years) and five population subgroups with high smoking prevalence or smoking risk. Using nine graphic labels, this study collected participant data in the field via an iPad-administered survey and card sorting of graphic warning labels. This paper reports on findings for AI/AN participants. After viewing graphic warning labels, participants rated their likelihood of talking about smoking risks to friends, parents and siblings higher than their likelihood of talking to teachers and doctors. Further, this study found that certain labels (eg, the label of the toddler in the smoke cloud) made them think about their friends and family who smoke. Given the influence of community social networks on health beliefs and attitudes, health communication using graphic warning labels could effect change in the smoking habits of AI/AN community members. Study findings suggest that graphic labels could serve as stimuli for conversations about the risks of smoking among AI/AN community members, and could be an important element of a peer-to-peer smoking cessation effort.

A novel coherent optical en/decoder for optical label processing of OCDM-based optical packets switching networks

NASA Astrophysics Data System (ADS)

Zhang, Chongfu; Qiu, Kun

2007-11-01

A coherent optical en/decoder based on photonic crystal (PhC) for optical code-division-multiple (OCDM)-based optical label (OCDM-OL) optical packets switching (OPS) networks is proposed in this paper. In this scheme, the optical pulse phase and time delay can be flexibly controlled by the photonic crystal phase shifter and delayer using the appropriate design of fabrication. In this design, the combination calculation of the impurity and normal period layers is applied, according to the PhC transmission matrix theorem. The design and theoretical analysis of the PhC-based optical coherent en/decoder is mainly focused. In addition, the performances of the PhC-based optical en/decoders are analyzed in detail. The reflection, the transmission, delay characteristic and the optical spectrum of pulse en/decoded are studied for the waves tuned in the photonic band-gap by the numerical calculation, taking into account 1-Dimension (1D) PhC. Theoretical analysis and numerical results show that optical pulse is achieved to properly phase modulation and time delay by the proposed scheme, optical label based on OCDM is rewrote successfully by new code for OCDM-based OPS (OCDM-OPS), and an over 8.5 dB ration of auto- and cross-correlation is gained, which demonstrates the applicability of true pulse phase modulation in a number of applications.

The Interplay between Uncertainty Monitoring and Working Memory: Can Metacognition Become Automatic?

PubMed Central

Coutinho, Mariana V. C.; Redford, Joshua S.; Church, Barbara A.; Zakrzewski, Alexandria C.; Couchman, Justin J.; Smith, J. David

2016-01-01

The uncertainty response has grounded the study of metacognition in nonhuman animals. Recent research has explored the processes supporting uncertainty monitoring in monkeys. It revealed that uncertainty responding in contrast to perceptual responding depends on significant working memory resources. The aim of the present study was to expand this research by examining whether uncertainty monitoring is also working memory demanding in humans. To explore this issue, human participants were tested with or without a cognitive load on a psychophysical discrimination task including either an uncertainty response (allowing the decline of difficult trials) or a middle-perceptual response (labeling the same intermediate trial levels). The results demonstrated that cognitive load reduced uncertainty responding, but increased middle responding. However, this dissociation between uncertainty and middle responding was only observed when participants either lacked training or had very little training with the uncertainty response. If more training was provided, the effect of load was small. These results suggest that uncertainty responding is resource demanding, but with sufficient training, human participants can respond to uncertainty either by using minimal working memory resources or effectively sharing resources. These results are discussed in relation to the literature on animal and human metacognition. PMID:25971878

Site-Specific Bioorthogonal Labeling for Fluorescence Imaging of Intracellular Proteins in Living Cells.

PubMed

Peng, Tao; Hang, Howard C

2016-11-02

Over the past years, fluorescent proteins (e.g., green fluorescent proteins) have been widely utilized to visualize recombinant protein expression and localization in live cells. Although powerful, fluorescent protein tags are limited by their relatively large sizes and potential perturbation to protein function. Alternatively, site-specific labeling of proteins with small-molecule organic fluorophores using bioorthogonal chemistry may provide a more precise and less perturbing method. This approach involves site-specific incorporation of unnatural amino acids (UAAs) into proteins via genetic code expansion, followed by bioorthogonal chemical labeling with small organic fluorophores in living cells. While this approach has been used to label extracellular proteins for live cell imaging studies, site-specific bioorthogonal labeling and fluorescence imaging of intracellular proteins in live cells is still challenging. Herein, we systematically evaluate site-specific incorporation of diastereomerically pure bioorthogonal UAAs bearing stained alkynes or alkenes into intracellular proteins for inverse-electron-demand Diels-Alder cycloaddition reactions with tetrazine-functionalized fluorophores for live cell labeling and imaging in mammalian cells. Our studies show that site-specific incorporation of axial diastereomer of trans-cyclooct-2-ene-lysine robustly affords highly efficient and specific bioorthogonal labeling with monosubstituted tetrazine fluorophores in live mammalian cells, which enabled us to image the intracellular localization and real-time dynamic trafficking of IFITM3, a small membrane-associated protein with only 137 amino acids, for the first time. Our optimized UAA incorporation and bioorthogonal labeling conditions also enabled efficient site-specific fluorescence labeling of other intracellular proteins for live cell imaging studies in mammalian cells.

2013-01-01

Obesity is a significant public health concern that disproportionally affects low-income and minority populations. Recent policies mandating the posting of calories on menus in fast food chain restaurants have not proven to uniformly influence food choice. This qualitative research study uses focus groups to study individual and environmental factors affecting the usage of these menu labels among low-income, minority populations. Ten focus groups targeting low-income residents (n=105) were conducted at various community organizations throughout NYC in Spanish, English, or a combination of both languages, over a nine-month period in 2011. In late 2011 and early 2012, transcripts were coded through the process of thematic analysis using Atlas.ti for naturally emerging themes, influences, and determinants of food choice. Few used menu labels, despite awareness. Among the themes pertaining to menu label usage, price and time constraints, confusion and lack of understanding of caloric values, as well as the priority of preference, hunger, and habitual ordering habits were most frequently cited as barriers to menu label usage. Based on the individual and external influences on food choice that often take priority over calorie consideration, a modified approach may be necessary to make menu labels more effective and user-friendly.

This study presents a machine learning method that increases the number of identified bases in Sanger Sequencing. The system post-processes a KB basecalled chromatogram. It selects a recoverable subset of N-labels in the KB-called chromatogram to replace with basecalls (A,C,G,T). An N-label correction is defined given an additional read of the same sequence, and a human finished sequence. Corrections are added to the dataset when an alignment determines the additional read and human agree on the identity of the N-label. KB must also rate the replacement with quality value of in the additional read. Corrections are only available during system training. Developing the system, nearly 850,000 N-labels are obtained from Barcode of Life Datasystems, the premier database of genetic markers called DNA Barcodes. Increasing the number of correct bases improves reference sequence reliability, increases sequence identification accuracy, and assures analysis correctness. Keeping with barcoding standards, our system maintains an error rate of percent. Our system only applies corrections when it estimates low rate of error. Tested on this data, our automation selects and recovers: 79 percent of N-labels from COI (animal barcode); 80 percent from matK and rbcL (plant barcodes); and 58 percent from non-protein-coding sequences (across eukaryotes).

Self-medication as an alternative is used to reduce the severity of diarrhea. Optimal treatment can be done by increasing the rationalization of self-medication on diarrhea. This can be achieved with good knowledge about self-medication, which is in turn influenced by level of education. The aim of this study was to determine the relationship of knowledge and education level to rationality of self-medication on childhood diarrhea around the Code River in Jogoyudan, Jetis, Yogyakarta. The study was conducted by cross-sectional analytical observational design. The subjects were mothers who had children aged 2-11 years who had experienced diarrhea and had self-medication. Questionnaires were used to assess the rationality of self-medication on children's diarrhea by the parents. The respondents were askeds to fill out about indications, right drugs, doses, time intervals and periods of drug administration. Data were analyzed using chi- square. It was showed that of 40 respondents, 14 respondents (35%) performed rational self-medication on children's diarrhea and 26 respondents (65%). did not rationalize the treatment. The results of a bivariate test obtained a chi-square value of 9.808 (> 3.841) and a p value of 0.002 (<0.05) on the relationship between education level and rationality of self-medication and a chi-square value of 19.476 (> 3.841) and a p value of 0.000 (<0.05) on relationship between knowledge and rationality of self- medication. The conclusion of this study is that there is a correlation between knowledge and level of education and rationality of self-medication on childhood diarrhea on the Code River banks in Jogoyudan, Jetis, Yogyakarta.

Polish Labour Code provides employees with a range of solutions (benefits) supporting them in achieving balance between work and private life. This paper was aimed at indicating availability and the use of legal benefits supporting work-life balance (WLB) among Polish workers of small and medium enterprises. The study sample included 219 respondents, aged 22-64, working in small and medium enterprises and employed on the basis of employment contracts for at least a year. The respondents completed a questionnaire on availability and the use of benefits guaranteed by the Polish Labour Code, referring to their current workplaces. Most frequently the studied employees took sick leave because of one's own illness and leave on demand. In our sample, 45% of the women took maternity leave and 26% of the men took paternity leave. The respondents took educational and parental leave the least frequently. More than half of the respondents (58%) did not return to the same position after leave devoted to childcare, even though they had such a possibility. In fact, most of work-life balance benefits guaranteed by law were available to the employees of small and medium enterprises, regardless of their gender. Availability and the use of the majority of benefits were similar among the women and men. Availability of benefits depended on the specificity of industry and a profession, thus, future research on work-life balance policy should control for variables related to the character of work.

Use of communication theories in the development of pictorial health warning labels (graphic warning labels) for cigarette packaging might enhance labels' impact on motivation to quit, but research has been limited, particularly among low socioeconomic status (SES) populations in the U.S. This qualitative study explored perceptions of theory-based graphic warning labels and their role in motivation to quit among low-income smokers. A cross-sectional qualitative study was conducted with 25 low-income adult smokers in Baltimore, Maryland, who were purposively sampled from a community-based source population. Semi-structured, in-depth interviews were conducted from January to February 2014. Participants were asked about the motivational impact of 12 labels falling into four content categories: negative depictions of the health effects of smoking to smokers and others, and positive depictions of the benefits of quitting to smokers and others. Data were coded using a combined inductive/deductive approach and analyzed thematically through framework analysis. Labels depicting negative health effects to smokers were identified as most motivational, followed by labels depicting negative health effects to others. Reasons included perceived severity of and susceptibility to the effects, negative emotional reactions (such as fear), and concern for children. Labels about the benefits of quitting were described as motivational because of their hopefulness, characters as role models, and desire to improve family health. Reasons why labels were described as not motivational included lack of impact on perceived severity/susceptibility, low credibility, and fatalistic attitudes regarding the inevitability of disease. Labels designed to increase risk perceptions from smoking might be significant sources of motivation for low SES smokers. Findings suggest innovative theory-driven approaches for the design of labels, such as using former smokers as role models, contrasting healthy and unhealthy characters, and socially-oriented labels, might motivate low SES smokers to quit.

Statistics of single unit responses in the human medial temporal lobe: A sparse and overdispersed code

NASA Astrophysics Data System (ADS)

Magyar, Andrew

The recent discovery of cells that respond to purely conceptual features of the environment (particular people, landmarks, objects, etc) in the human medial temporal lobe (MTL), has raised many questions about the nature of the neural code in humans. The goal of this dissertation is to develop a novel statistical method based upon maximum likelihood regression which will then be applied to these experiments in order to produce a quantitative description of the coding properties of the human MTL. In general, the method is applicable to any experiments in which a sequence of stimuli are presented to an organism while the binary responses of a large number of cells are recorded in parallel. The central concept underlying the approach is the total probability that a neuron responds to a random stimulus, called the neuronal sparsity. The model then estimates the distribution of response probabilities across the population of cells. Applying the method to single-unit recordings from the human medial temporal lobe, estimates of the sparsity distributions are acquired in four regions: the hippocampus, the entorhinal cortex, the amygdala, and the parahippocampal cortex. The resulting distributions are found to be sparse (large fraction of cells with a low response probability) and highly non-uniform, with a large proportion of ultra-sparse neurons that possess a very low response probability, and a smaller population of cells which respond much more frequently. Rammifications of the results are discussed in relation to the sparse coding hypothesis, and comparisons are made between the statistics of the human medial temporal lobe cells and place cells observed in the rodent hippocampus.

Measuring Changes in Social Behavior during a Social Skills Intervention for Higher-Functioning Children and Adolescents with Autism Spectrum Disorder

McMahon, Camilla M.; Vismara, Laurie A.; Solomon, Marjorie

2013-01-01

The social behavior of children and adolescents with Autism Spectrum Disorder was evaluated weekly over 19 weeks of a social skills training program. Participants’ vocalizations were coded as initiating, responding, or other (e.g., self-talk). Participants’ interactions were coded as dyadic peer interactions, dyadic leader interactions, interactions with a group of peers, interactions with a group of peer(s) and leader(s), or time spent by self. Over the course of the intervention, participants made fewer initiating and other vocalizations, more responding vocalizations, spent more time interacting with a group of peers, and spent marginally less time interacting with a leader. Gender, age, and intervention attendance effects on social behavior are also noted. PMID:23239098

Immunotherapy using checkpoint-blocking antibodies against targets such as CTLA-4 and PD-1 can cure melanoma and non–small cell lung cancer in a subset of patients. The presence of CD8 T cells in the tumor correlates with improved survival. We show that immuno–positron emission tomography (immuno-PET) can visualize tumors by detecting infiltrating lymphocytes and, through longitudinal observation of individual animals, distinguish responding tumors from those that do not respond to therapy. We used 89Zr-labeled PEGylated single-domain antibody fragments (VHHs) specific for CD8 to track the presence of intratumoral CD8+ T cells in the immunotherapy-susceptible B16 melanoma model in response to checkpoint blockade. A 89Zr-labeled PEGylated anti-CD8 VHH detected thymus and secondary lymphoid structures as well as intratumoral CD8 T cells. Animals that responded to CTLA-4 therapy showed a homogeneous distribution of the anti-CD8 PET signal throughout the tumor, whereas more heterogeneous infiltration of CD8 T cells correlated with faster tumor growth and worse responses. To support the validity of these observations, we used two different transplantable breast cancer models, yielding results that conformed with predictions based on the antimelanoma response. It may thus be possible to use immuno-PET and monitor antitumor immune responses as a prognostic tool to predict patient responses to checkpoint therapies. PMID:28666979

GALEN has developed a language independent common reference model based on a medically oriented ontology and practical tools and techniques for managing healthcare terminology including natural language processing. GALEN-IN-USE is the current phase which applied the modelling and the tools to the development or the updating of coding systems for surgical procedures in different national coding centers co-operating within the European Federation of Coding Centre (EFCC) to create a language independent knowledge repository for multicultural Europe. We used an integrated set of artificial intelligence terminology tools named CLAssification Manager workbench to process French professional medical language rubrics into intermediate dissections and to the Grail reference ontology model representation. From this language independent concept model representation we generate controlled French natural language. The French national coding centre is then able to retrieve the initial professional rubrics with different categories of concepts, to compare the professional language proposed by expert clinicians to the French generated controlled vocabulary and to finalize the linguistic labels of the coding system in relation with the meanings of the conceptual system structure.

Use of fluorescent proteins and color-coded imaging to visualize cancer cells with different genetic properties.

PubMed

Hoffman, Robert M

2016-03-01

Fluorescent proteins are very bright and available in spectrally-distinct colors, enable the imaging of color-coded cancer cells growing in vivo and therefore the distinction of cancer cells with different genetic properties. Non-invasive and intravital imaging of cancer cells with fluorescent proteins allows the visualization of distinct genetic variants of cancer cells down to the cellular level in vivo. Cancer cells with increased or decreased ability to metastasize can be distinguished in vivo. Gene exchange in vivo which enables low metastatic cancer cells to convert to high metastatic can be color-coded imaged in vivo. Cancer stem-like and non-stem cells can be distinguished in vivo by color-coded imaging. These properties also demonstrate the vast superiority of imaging cancer cells in vivo with fluorescent proteins over photon counting of luciferase-labeled cancer cells.

Neurons in the rostral superior temporal sulcus (STS) are responsive to displays of body movements. We employed a parametric action space to determine how similarities among actions are represented by visual temporal neurons and how form and motion information contributes to their responses. The stimulus space consisted of a stick-plus-point-light figure performing arm actions and their blends. Multidimensional scaling showed that the responses of temporal neurons represented the ordinal similarity between these actions. Further tests distinguished neurons responding equally strongly to static presentations and to actions ("snapshot" neurons), from those responding much less strongly to static presentations, but responding well when motion was present ("motion" neurons). The "motion" neurons were predominantly found in the upper bank/fundus of the STS, and "snapshot" neurons in the lower bank of the STS and inferior temporal convexity. Most "motion" neurons showed strong response modulation during the course of an action, thus responding to action kinematics. "Motion" neurons displayed a greater average selectivity for these simple arm actions than did "snapshot" neurons. We suggest that the "motion" neurons code for visual kinematics, whereas the "snapshot" neurons code for form/posture, and that both can contribute to action recognition, in agreement with computation models of action recognition.

2014-09-01

The Psychosocial Section of the Criminal Executions Court of the Federal District Court of Justice assists people who are under civil commitment, namely a legal sentence that labels them as sick people and criminals. In the juridical context, there are two options facing them: outpatient treatment or internment in a secure hospital facility and psychiatric treatment. In these options, requirements, such as tests to verify the cessation of danger, duration of imprisonment and existence of a relative who can shelter them, are examined to permit a favorable judicial decision of conditional release leading to removal from the sphere of justice. This is a third possible path. Through the analysis of an emblematic case, this article seeks to examine the sentence imposed on these people. The intention is, therefore, to give voice to the unimputable and/or the semi-imputable, people who are considered wholly or partially unable to respond to the illicit nature of the act they have committed, according to the Brazilian Criminal Code. The interlocution and the challenges between law and psychology in the juridical context emerge as a possibility by them of building another discourse, a line of thought that seeks the acquisition of autonomy and responsibility.

New York State Public Health System Response to Hurricane Sandy: Lessons From the Field.

2016-06-01

The aim of this study was to conduct interviews with public health staff who responded to Hurricane Sandy and to analyze their feedback to assess response strengths and challenges and recommend improvements for future disaster preparedness and response. Qualitative analysis was conducted of information from individual confidential interviews with 35 staff from 3 local health departments in New York State (NYS) impacted by Hurricane Sandy and the NYS Department of Health. Staff were asked about their experiences during Hurricane Sandy and their recommendations for improvements. Open coding was used to analyze interview transcripts for reoccurring themes, which were labeled as strengths, challenges, or recommendations and then categorized into public health preparedness capabilities. The most commonly cited strengths, challenges, and recommendations related to the Hurricane Sandy public health response in NYS were within the emergency operations coordination preparedness capability, which includes the abilities of health department staff to partner among government agencies, coordinate with emergency operation centers, conduct routine conference calls with partners, and manage resources. Health departments should ensure that emergency planning includes protocols to coordinate backup staffing, delineation of services that can be halted during disasters, clear guidelines to coordinate resources across agencies, and training for transitioning into unfamiliar disaster response roles.

Objective To examine how type and severity of patients’ negative emotions influence oncologists’ responses and subsequent conversations. Methods We analyzed 264 audio-recorded conversations between advanced cancer patients and their oncologists. Conversations were coded for patients’ expressions of negative emotion, which were categorized by type of emotion and severity. Oncologists’ responses were coded as using either empathic language or blocking and distancing approaches. Results Patients presented fear more often than anger or sadness; severity of disclosures was most often moderate. Oncologists responded to 35% of these negative emotional disclosures with empathic language. They were most empathic when patients presented intense emotions. Responding empathically to patients’ emotional disclosures lengthened discussions by an average of only 21 seconds. Conclusion Greater response rates to severe emotions suggest oncologists may recognize negative emotions better when patients express them more intensely. Oncologists were least responsive to patient fear and responded with greatest empathy to sadness. Practice Implications Oncologists may benefit from additional training to recognize negative emotions, even when displayed without intensity. Teaching cancer patients to better articulate their emotional concerns may also enhance patient-oncologist communication. PMID:19041211

Profiling structured product labeling with NDF-RT and RxNorm

PubMed Central

2012-01-01

Background Structured Product Labeling (SPL) is a document markup standard approved by Health Level Seven (HL7) and adopted by United States Food and Drug Administration (FDA) as a mechanism for exchanging drug product information. The SPL drug labels contain rich information about FDA approved clinical drugs. However, the lack of linkage to standard drug ontologies hinders their meaningful use. NDF-RT (National Drug File Reference Terminology) and NLM RxNorm as standard drug ontology were used to standardize and profile the product labels. Methods In this paper, we present a framework that intends to map SPL drug labels with existing drug ontologies: NDF-RT and RxNorm. We also applied existing categorical annotations from the drug ontologies to classify SPL drug labels into corresponding classes. We established the classification and relevant linkage for SPL drug labels using the following three approaches. First, we retrieved NDF-RT categorical information from the External Pharmacologic Class (EPC) indexing SPLs. Second, we used the RxNorm and NDF-RT mappings to classify and link SPLs with NDF-RT categories. Third, we profiled SPLs using RxNorm term type information. In the implementation process, we employed a Semantic Web technology framework, in which we stored the data sets from NDF-RT and SPLs into a RDF triple store, and executed SPARQL queries to retrieve data from customized SPARQL endpoints. Meanwhile, we imported RxNorm data into MySQL relational database. Results In total, 96.0% SPL drug labels were mapped with NDF-RT categories whereas 97.0% SPL drug labels are linked to RxNorm codes. We found that the majority of SPL drug labels are mapped to chemical ingredient concepts in both drug ontologies whereas a relatively small portion of SPL drug labels are mapped to clinical drug concepts. Conclusions The profiling outcomes produced by this study would provide useful insights on meaningful use of FDA SPL drug labels in clinical applications through standard drug ontologies such as NDF-RT and RxNorm.

Patients' views on price shopping and price transparency.

Driven by the growth of high deductibles and price transparency initiatives, patients are being encouraged to search for prices before seeking care, yet few do so. To understand why this is the case, we interviewed individuals who were offered access to a widely used price transparency website through their employer. Qualitative interviews. We interviewed individuals enrolled in a preferred provider organization product through their health plan about their experience using the price transparency tool (if they had done so), their past medical experiences, and their opinions on shopping for care. All interviews were transcribed and manually coded using a thematic coding guide. In general, respondents expressed frustration with healthcare costs and had a positive opinion of the idea of price shopping in theory, but 2 sets of barriers limited their ability to do so in reality. The first was the salience of searching for price information. For example, respondents recognized that due to their health plan benefits design, they would not save money by switching to a lower-cost provider. Second, other factors were more important than price for respondents when choosing a provider, including quality and loyalty to current providers. We found a disconnect between respondents' enthusiasm for price shopping and their reported use of a price transparency tool to shop for care. However, many did find the tool useful for other purposes, including checking their claims history. Addressing the barriers to price shopping identified by respondents can help inform ongoing and future price transparency initiatives.

[Development and Application of Catalytic Tyrosine Modification].

 The chemical labeling of proteins with synthetic probes is a key technique used in chemical biology, protein-based therapy, and material science. Much of the chemical labeling of native proteins, however, depends on the labeling of lysine and cysteine residues. While those methods have significantly contributed to native protein labeling, alternative methods that can modify different amino acid residues are still required. Herein we report the development of a novel methodology of tyrosine labeling, inspired by the luminol chemiluminescence reaction. Tyrosine residues are often exposed on a protein's surface and are thus expected to be good targets for protein functionalization. In our studies so far, we have found that 1) hemin oxidatively activates luminol derivatives as a catalyst, 2) N-methyl luminol derivative specifically forms a covalent bond with a tyrosine residue among the 20 kinds of natural amino acid residues, and 3) the efficiency of tyrosine labeling with N-methyl luminol derivative is markedly improved by using horseradish peroxidase (HRP) as a catalyst. We were able to use molecular oxygen as an oxidant under HRP/NADH conditions. By using these methods, the functionalization of purified proteins was carried out. Because N-methyl luminol derivative is an excellent protein labeling reagent that responds to the activation of peroxidase, this new method is expected to open doors to such biological applications as the signal amplification of HRP-conjugated antibodies and the detection of protein association in combination with peroxidase-tag technology.

Nutritional information and health warnings on wine labels: Exploring consumer interest and preferences.

Annunziata, A; Pomarici, E; Vecchio, R; Mariani, A

This paper aims to contribute to the current debate on the inclusion of nutritional information and health warnings on wine labels, exploring consumers' interest and preferences. The results of a survey conducted on a sample of Italian wine consumers (N = 300) show the strong interest of respondents in the inclusion of such information on the label. Conjoint analysis reveals that consumers assign greater utility to health warnings, followed by nutritional information. Cluster analysis shows the existence of three different consumer segments. The first cluster, which included mainly female consumers (over 55) and those with high wine involvement, revealed greater awareness of the links between wine and health and better knowledge of wine nutritional properties, preferring a more detailed nutritional label, such as a panel with GDA%. By contrast, the other two clusters, consisting of individuals who generally find it more difficult to understand nutritional labels, preferred the less detailed label of a glass showing calories. The second and largest cluster comprising mainly younger men (under 44), showed the highest interest in health warnings while the third cluster - with a relatively low level of education - preferred the specification of the number of glasses not to exceed. Our results support the idea that the policy maker should consider introducing a mandatory nutritional label in the easier-to-implement and not-too-costly form of a glass with calories, rotating health warnings and the maximum number of glasses not to exceed.

The impact of price and nutrition labelling on sugary drink purchases: Results from an experimental marketplace study.

PubMed

Acton, Rachel B; Hammond, David

2018-02-01

To examine the effect of front-of-package (FOP) nutrition labelling and sugary drink taxation on consumer beverage purchases. A total of 675 respondents aged 16 years and older participated in an experimental marketplace study using a 4 × 5 within-between group design. Participants were randomised to one of four labelling conditions (no label; star rating; high sugar symbol; health warning) and completed five within-subject purchase tasks. Beverage prices in each task corresponded to 'tax' conditions: 0%, 10%, 20%, 30% and a variable tax proportional to free sugar level. In each task, participants selected from 20 commercially available beverages; upon conclusion, one of five selections was randomly chosen for purchase. As price increased, participants were significantly less likely to select a sugary drink, and selected drinks with fewer calories and less free sugar (p < 0.001 for all). The overall effect of labelling was not statistically significant, although there was a trend for the 'high sugar' label to reduce the likelihood of selecting a sugary drink (p = 0.11) and encouraging participants to select drinks with less free sugar (p = 0.11). Increasing price was associated with reduced sugary drink purchases. Enhanced FOP labelling results highlight the need for further research to investigate their potential impact. The study adds empirical support for taxation to reduce sugary drink consumption. Copyright © 2017 Elsevier Ltd. All rights reserved.

Nutrition labels in bar graph format deemed most useful for consumer purchase decisions using adaptive conjoint analysis.

1991-07-01

This study estimated the effects of changing multiple levels and combinations of nutrition information format, load, expression, and order on consumers' perceptions of label usefulness in purchase decisions using adaptive conjoint analysis. A shopping mall intercept survey, which was administered by a marketing research firm, assessed consumer preferences for 12 label alternatives produced on Campbell's soup cans to portray nutrition information realistically; 252 of 258 respondents completed the computer interactive interview. Consumers significantly preferred the bar graph format to the bar graph/nutrient density and traditional label formats. Consumers considered the bar graph/nutrient density format to be as useful as the traditional label format. There was a highly significant difference among the three levels of information load; the most information load was preferred regardless of nutrient importance. Consumers significantly preferred nutrition information stated in absolute numbers and percentages vs in absolute numbers only in traditional, or in percentages only expressions. There was a significant difference between consumer preferences for the two types of information order. The findings indicate that consumers clearly preferred the nutrition label that displayed all nutrient values using a bar graph format, offered the most information load, and expressed nutrient values using both absolute numbers and percentages. Consumers also preferred nutrition information rearranged in an order that grouped nutrients that should be consumed in adequate amounts on the top, calories in the middle, and nutrients that should be consumed in lesser amounts on the bottom of the label.

Practical moral codes in the transgenic organism debate.

2004-01-01

In one study funded by the United States Department of Agriculture, people from North Dakota were interviewed to discover which moral principles they use in evaluating the morality of transgenic organisms and their introduction into markets. It was found that although the moral codes the human subjects employed were very similar, their views on transgenics were vastly different. In this paper, the codes that were used by the respondents are developed, compared to that of the academically composed Belmont Report, and then modified to create the more practical Common Moral Code. At the end, it is shown that the Common Moral Code has inherent inconsistency flaws that might be resolvable, but would require extensive work on the definition of terms and principles. However, the effort is worthwhile, especially if it results in a common moral code that all those involved in the debate are willing to use in negotiating a resolution to their differences.

A novel strategy consisting of cleavable Isotope-Coded Affinity Tag (cICAT) combined with MASCOT Distiller was evaluated as a tool for the quantification of proteins in "abnormal" patient plasma, prepared by pooling samples from patients with acute stroke. Quantification of all light and heavy cICAT-labelled peptide ion pairs was obtained using MASCOT Distiller combined with a proprietary software. Peptides displaying differences were selected for identification by MS. These preliminary results show the promise of our approach to identify potential biomarkers.

Despite the overall high degree of response to pharmacotherapy, consensus is lacking on how to judge clinical response or define optimal treatment/remission when treating adults with attention-deficit/hyperactivity disorder (ADHD). This study examined clinical response and symptomatic remission in analyses of 2 studies of lisdexamfetamine dimesylate (LDX) in adults with ADHD. In a 4-week, double-blind, forced-dose trial, adults with ADHD were randomized to LDX 30, 50, and 70 mg/day (mg/d) or placebo. In a second, open-label, follow-up trial, adults entering from the 4-week study were titrated to an "optimal" LDX dose (30 mg/d [n=44], 50 mg/d [n=112], and 70 mg/d [n=171]) over 4 weeks, and maintained for 11 additional months. The ADHD Rating Scale IV (ADHD-RS-IV) with adult prompts and the Clinical Global Impressions-Improvement (CGI-I) scale assessed efficacy. Clinical response was defined, post hoc, as ≥30% reduction from baseline in ADHD-RS-IV and CGI-I rating of 1 or 2; symptomatic remission was defined as ADHD-RS-IV total score ≤18. Log rank analysis examined overall significance among the treatment groups in time to response or remission. Four hundred and fourteen participants in the 4-week study and 345 in the open-label, extension study were included in the efficacy populations. All LDX groups improved by ADHD-RS-IV and CGI-I scores in both studies. In the 4-week study (n=414), 69.3% responded and 45.5% achieved remission with LDX (all doses); 37.1% responded and 16.1% achieved remission with placebo; time (95% CI) to median clinical response (all LDX doses) was 15.0 (15.0, 17.0) days and to remission was 31.0 (28.0, 37.0) days (P<.0001 overall). In the open-label study, with LDX (all doses), 313 (95.7%) and 278 (85.0%) of 327 participants with evaluable maintenance-phase data met criteria for response and remission, respectively. Of participants who completed dose optimization, 75.2% remained responders and 65.7% remained in remission in the 12-month study. Overall, 285 (82.6%) and 227 (65.8%) of 345 participants were responders and remitters, respectively, at their final visits. In the long-term study, with open-label, dose-optimized LDX treatment, most adults with ADHD achieved clinical response and/or symptomatic remission; almost two-thirds maintained symptomatic remission over the remaining 11 months.

Reverse Stroop Effects with Untranslated Responses

ERIC Educational Resources Information Center

Blais, Chris; Besner, Derek

2006-01-01

Translation accounts have argued that the presence of a Stroop effect in the context of a nonvocal untranslated response is caused by verbal mediation. In its simplest form, color-labeled buttons are translated into a verbal code that interferes with color responses. On this logic, in the reverse Stroop task (identify the word; ignore the color),…

Site-specific fluorescent labeling of proteins inside live mammalian cells has been achieved by employing Streptolysin O, a bacterial enzyme which forms temporary pores in the membrane and allows delivery of virtually any fluorescent probes, ranging from labeled IgG's to small ligands, with high efficiency (>85% of cells). The whole process, including recovery, takes 30 min, and the cell is ready to be imaged immediately. A variety of cell viability tests were performed after treatment with SLO to ensure that the cells have intact membranes, are able to divide, respond normally to signaling molecules, and maintains healthy organelle morphology. When combined with Oxyrase, a cell-friendly photostabilizer, a ~20x improvement in fluorescence photostability is achieved. By adding in glutathione, fluorophores are made to blink, enabling super-resolution fluorescence with 20-30 nm resolution over a long time (~30 min) under continuous illumination. Example applications in conventional and super-resolution imaging of native and transfected cells include p65 signal transduction activation, single molecule tracking of kinesin, and specific labeling of a series of nuclear and cytoplasmic protein complexes.

Coset Codes Viewed as Terminated Convolutional Codes

NASA Technical Reports Server (NTRS)

Fossorier, Marc P. C.; Lin, Shu

1996-01-01

In this paper, coset codes are considered as terminated convolutional codes. Based on this approach, three new general results are presented. First, it is shown that the iterative squaring construction can equivalently be defined from a convolutional code whose trellis terminates. This convolutional code determines a simple encoder for the coset code considered, and the state and branch labelings of the associated trellis diagram become straightforward. Also, from the generator matrix of the code in its convolutional code form, much information about the trade-off between the state connectivity and complexity at each section, and the parallel structure of the trellis, is directly available. Based on this generator matrix, it is shown that the parallel branches in the trellis diagram of the convolutional code represent the same coset code C(sub 1), of smaller dimension and shorter length. Utilizing this fact, a two-stage optimum trellis decoding method is devised. The first stage decodes C(sub 1), while the second stage decodes the associated convolutional code, using the branch metrics delivered by stage 1. Finally, a bidirectional decoding of each received block starting at both ends is presented. If about the same number of computations is required, this approach remains very attractive from a practical point of view as it roughly doubles the decoding speed. This fact is particularly interesting whenever the second half of the trellis is the mirror image of the first half, since the same decoder can be implemented for both parts.

Neurobiological research has implicated the dopamine and serotonin systems in the pathogenesis of autism. Open-label reports suggest that the serotonin2A-dopamine D2 antagonist risperidone may be safe and effective in reducing the interfering symptoms of patients with autism. Thirty-one adults (age [mean+/-SD], 28.1+/-7.3 years) with autistic disorder (n=17) or pervasive developmental disorder not otherwise specified (n=14) participated in a 12-week double-blind, placebo-controlled trial of risperidone. Patients treated with placebo subsequently received a 12-week open-label trial of risperidone. For persons completing the study, 8 (57%) of 14 patients treated with risperidone were categorized as responders (daily dose [mean+/-SD], 2.9+/-1.4 mg) compared with none of 16 in the placebo group (P<.002). Risperidone was superior to placebo in reducing repetitive behavior (P<.001), aggression (P<.001), anxiety or nervousness (P<.02), depression (P<.03), irritability (P<.01), and the overall behavioral symptoms of autism (P<.02). Objective, measurable change in social behavior and language did not occur. Nine (60%) of 15 patients who received treatment with open-label risperidone following the double-blind placebo phase responded. Other than mild, transient sedation, risperidone was well tolerated, with no evidence of extrapyramidal effects, cardiac events, or seizures. Risperidone is more effective than placebo in the short-term treatment of symptoms of autism in adults.

Labeling proteins on live mammalian cells using click chemistry.

Nikić, Ivana; Kang, Jun Hee; Girona, Gemma Estrada; Aramburu, Iker Valle; Lemke, Edward A

2015-05-01

We describe a protocol for the rapid labeling of cell-surface proteins in living mammalian cells using click chemistry. The labeling method is based on strain-promoted alkyne-azide cycloaddition (SPAAC) and strain-promoted inverse-electron-demand Diels-Alder cycloaddition (SPIEDAC) reactions, in which noncanonical amino acids (ncAAs) bearing ring-strained alkynes or alkenes react, respectively, with dyes containing azide or tetrazine groups. To introduce ncAAs site specifically into a protein of interest (POI), we use genetic code expansion technology. The protocol can be described as comprising two steps. In the first step, an Amber stop codon is introduced--by site-directed mutagenesis--at the desired site on the gene encoding the POI. This plasmid is then transfected into mammalian cells, along with another plasmid that encodes an aminoacyl-tRNA synthetase/tRNA (RS/tRNA) pair that is orthogonal to the host's translational machinery. In the presence of the ncAA, the orthogonal RS/tRNA pair specifically suppresses the Amber codon by incorporating the ncAA into the polypeptide chain of the POI. In the second step, the expressed POI is labeled with a suitably reactive dye derivative that is directly supplied to the growth medium. We provide a detailed protocol for using commercially available ncAAs and dyes for labeling the insulin receptor, and we discuss the optimal surface-labeling conditions and the limitations of labeling living mammalian cells. The protocol involves an initial cloning step that can take 4-7 d, followed by the described transfections and labeling reaction steps, which can take 3-4 d.

Approach and Withdrawal Tendencies during Written Word Processing: Effects of Task, Emotional Valence, and Emotional Arousal

PubMed Central

Citron, Francesca M. M.; Abugaber, David; Herbert, Cornelia

2016-01-01

The affective dimensions of emotional valence and emotional arousal affect processing of verbal and pictorial stimuli. Traditional emotional theories assume a linear relationship between these dimensions, with valence determining the direction of a behavior (approach vs. withdrawal) and arousal its intensity or strength. In contrast, according to the valence-arousal conflict theory, both dimensions are interactively related: positive valence and low arousal (PL) are associated with an implicit tendency to approach a stimulus, whereas negative valence and high arousal (NH) are associated with withdrawal. Hence, positive, high-arousal (PH) and negative, low-arousal (NL) stimuli elicit conflicting action tendencies. By extending previous research that used several tasks and methods, the present study investigated whether and how emotional valence and arousal affect subjective approach vs. withdrawal tendencies toward emotional words during two novel tasks. In Study 1, participants had to decide whether they would approach or withdraw from concepts expressed by written words. In Studies 2 and 3 participants had to respond to each word by pressing one of two keys labeled with an arrow pointing upward or downward. Across experiments, positive and negative words, high or low in arousal, were presented. In Study 1 (explicit task), in line with the valence-arousal conflict theory, PH and NL words were responded to more slowly than PL and NH words. In addition, participants decided to approach positive words more often than negative words. In Studies 2 and 3, participants responded faster to positive than negative words, irrespective of their level of arousal. Furthermore, positive words were significantly more often associated with “up” responses than negative words, thus supporting the existence of implicit associations between stimulus valence and response coding (positive is up and negative is down). Hence, in contexts in which participants' spontaneous responses are based on implicit associations between stimulus valence and response, there is no influence of arousal. In line with the valence-arousal conflict theory, arousal seems to affect participants' approach-withdrawal tendencies only when such tendencies are made explicit by the task, and a minimal degree of processing depth is required.

2011-04-01

Despite regulatory restrictions, off-label marketing of pharmaceutical products has been common in the US. However, the scope of off-label marketing remains poorly characterized. We developed a typology for the strategies and practices that constitute off-label marketing. We obtained unsealed whistleblower complaints against pharmaceutical companies filed in US federal fraud cases that contained allegations of off-label marketing (January 1996-October 2010) and conducted structured reviews of them. We coded and analyzed the strategic goals of each off-label marketing scheme and the practices used to achieve those goals, as reported by the whistleblowers. We identified 41 complaints arising from 18 unique cases for our analytic sample (leading to US$7.9 billion in recoveries). The off-label marketing schemes described in the complaints had three non-mutually exclusive goals: expansions to unapproved diseases (35/41, 85%), unapproved disease subtypes (22/41, 54%), and unapproved drug doses (14/41, 34%). Manufacturers were alleged to have pursued these goals using four non-mutually exclusive types of marketing practices: prescriber-related (41/41, 100%), business-related (37/41, 90%), payer-related (23/41, 56%), and consumer-related (18/41, 44%). Prescriber-related practices, the centerpiece of company strategies, included self-serving presentations of the literature (31/41, 76%), free samples (8/41, 20%), direct financial incentives to physicians (35/41, 85%), and teaching (22/41, 54%) and research activities (8/41, 20%). Off-label marketing practices appear to extend to many areas of the health care system. Unfortunately, the most common alleged off-label marketing practices also appear to be the most difficult to control through external regulatory approaches.

To determine the presence of pregnancy warnings on over-the-counter (OTC) dermatologic products with hydroquinone, a potentially harmful ingredient. Data were obtained from the Food and Drug Administration National Drug Code Directory and Label Repository to identify OTC dermatologic products containing hydroquinone. Products were stratified based on pregnancy or general warning presence (WP) or absence (WA). Product characteristics were compared between groups: hydroquinone concentration, presence of external packaging, indication and warning statements. Of the 112 products studied, 21 had a pregnancy warning and 3 included a general warning against use: WP (n=24) and WA (n=88) group. External packaging was more prevalent in the WP group compared to WA (62.5% vs 29.5%, P=0.004). Majority of OTC dermatologic products containing hydroquinone did not have a pregnancy warning. This highlights the need for improved labeling and informs providers caring for pregnant women of OTC labeling limitations.

New Method for Producing Significant Amounts of RNA Labeled at Specific Sites | Center for Cancer Research

Cancer.gov

Among biomacromolecules, RNA is the most versatile, and it plays indispensable roles in almost all aspects of biology. For example, in addition to serving as mRNAs coding for proteins, RNAs regulate gene expression, such as controlling where, when, and how efficiently a gene gets expressed, participate in RNA processing, encode the genetic information of some viruses, serve as scaffolds, and even possess enzymatic activity. To study these RNAs and their biological functions and to make use of those RNA activities for biomedical applications, researchers first need to make various types of RNA. For structural biologists incorporating modified or labeled nucleotides at specific sites in RNA molecules of interest is critical to gain structural insight into RNA functions. However, placing labeled or modified residue(s) in desired positions in a large RNA has not been possible until now.

Joint Patch and Multi-label Learning for Facial Action Unit Detection

2016-01-01

The face is one of the most powerful channel of nonverbal communication. The most commonly used taxonomy to describe facial behaviour is the Facial Action Coding System (FACS). FACS segments the visible effects of facial muscle activation into 30+ action units (AUs). AUs, which may occur alone and in thousands of combinations, can describe nearly all-possible facial expressions. Most existing methods for automatic AU detection treat the problem using one-vs-all classifiers and fail to exploit dependencies among AU and facial features. We introduce joint-patch and multi-label learning (JPML) to address these issues. JPML leverages group sparsity by selecting a sparse subset of facial patches while learning a multi-label classifier. In four of five comparisons on three diverse datasets, CK+, GFT, and BP4D, JPML produced the highest average F1 scores in comparison with state-of-the art. PMID:27382243

Cross-cultural variability in respondent processing of survey questions may bias results from multiethnic samples. We analyzed behavior codes, which identify difficulties in the interactions of respondents and interviewers, from a discrimination module contained within a field test of the 2007 California Health Interview Survey. In all, 553 (English) telephone interviews yielded 13,999 interactions involving 22 items. Multilevel logistic regression modeling revealed that respondent age and several item characteristics (response format, customized questions, length, and first item with new response format), but not race/ethnicity, were associated with interactional problems. These findings suggest that item function within a multi-cultural, albeit English language, survey may be largely influenced by question features, as opposed to respondent characteristics such as race/ethnicity.

Some internal medicine residency program directors have expressed concerns that their third-year residents may have been subjected to inappropriate communication during the 2016 fellowship recruitment season. The authors sought to study applicants' interpersonal communication experiences with fellowship programs. Many respondents indicated that they had been asked questions that would constitute violations of the National Residency Matching Program (NRMP) Communications Code of Conduct agreement, including how they plan to rank specific programs. Moreover, female respondents were more likely to have been asked questions during interview experiences about other programs to which they applied, and about their family plans. Post-interview communication policies were not made clear to most applicants. These results suggest ongoing challenges for the internal medicine community to improve communication with applicants and uniform compliance with the NRMP communications code of conduct during the fellowship recruitment process.

Potential role of monkey inferior parietal neurons coding action semantic equivalences as precursors of parts of speech.

2010-01-01

The anterior portion of the inferior parietal cortex possesses comprehensive representations of actions embedded in behavioural contexts. Mirror neurons, which respond to both self-executed and observed actions, exist in this brain region in addition to those originally found in the premotor cortex. We found that parietal mirror neurons responded differentially to identical actions embedded in different contexts. Another type of parietal mirror neuron represents an inverse and complementary property of responding equally to dissimilar actions made by itself and others for an identical purpose. Here, we propose a hypothesis that these sets of inferior parietal neurons constitute a neural basis for encoding the semantic equivalence of various actions across different agents and contexts. The neurons have mirror neuron properties, and they encoded generalization of agents, differentiation of outcomes, and categorization of actions that led to common functions. By integrating the activities of these mirror neurons with various codings, we further suggest that in the ancestral primates' brains, these various representations of meaningful action led to the gradual establishment of equivalence relations among the different types of actions, by sharing common action semantics. Such differential codings of the components of actions might represent precursors to the parts of protolanguage, such as gestural communication, which are shared among various members of a society. Finally, we suggest that the inferior parietal cortex serves as an interface between this action semantics system and other higher semantic systems, through common structures of action representation that mimic language syntax.

Objective To assess the effect of coding quality on estimates of the incidence of diabetes in the UK between 1995 and 2014. Design A cross-sectional analysis examining diabetes coding from 1995 to 2014 and how the choice of codes (diagnosis codes vs codes which suggest diagnosis) and quality of coding affect estimated incidence. Setting Routine primary care data from 684 practices contributing to the UK Clinical Practice Research Datalink (data contributed from Vision (INPS) practices). Main outcome measure Incidence rates of diabetes and how they are affected by (1) GP coding and (2) excluding ‘poor’ quality practices with at least 10% incident patients inaccurately coded between 2004 and 2014. Results Incidence rates and accuracy of coding varied widely between practices and the trends differed according to selected category of code. If diagnosis codes were used, the incidence of type 2 increased sharply until 2004 (when the UK Quality Outcomes Framework was introduced), and then flattened off, until 2009, after which they decreased. If non-diagnosis codes were included, the numbers continued to increase until 2012. Although coding quality improved over time, 15% of the 666 practices that contributed data between 2004 and 2014 were labelled ‘poor’ quality. When these practices were dropped from the analyses, the downward trend in the incidence of type 2 after 2009 became less marked and incidence rates were higher. Conclusions In contrast to some previous reports, diabetes incidence (based on diagnostic codes) appears not to have increased since 2004 in the UK. Choice of codes can make a significant difference to incidence estimates, as can quality of recording. Codes and data quality should be checked when assessing incidence rates using GP data.

2012-01-01

Background Although the benefits of physical activity in preventing chronic medical conditions are well established, its impacts on infectious diseases, and seasonal influenza in particular, are less clearly defined. We examined the association between physical activity and influenza-coded outpatient visits, as a proxy for influenza infection. Methodology/Principal Findings We conducted a cohort study of Ontario respondents to Statistics Canada’s population health surveys over 12 influenza seasons. We assessed physical activity levels through survey responses, and influenza-coded physician office and emergency department visits through physician billing claims. We used logistic regression to estimate the risk of influenza-coded outpatient visits during influenza seasons. The cohort comprised 114,364 survey respondents who contributed 357,466 person-influenza seasons of observation. Compared to inactive individuals, moderately active (OR 0.83; 95% CI 0.74–0.94) and active (OR 0.87; 95% CI 0.77–0.98) individuals were less likely to experience an influenza-coded visit. Stratifying by age, the protective effect of physical activity remained significant for individuals <65 years (active OR 0.86; 95% CI 0.75–0.98, moderately active: OR 0.85; 95% CI 0.74–0.97) but not for individuals ≥65 years. The main limitations of this study were the use of influenza-coded outpatient visits rather than laboratory-confirmed influenza as the outcome measure, the reliance on self-report for assessing physical activity and various covariates, and the observational study design. Conclusion/Significance Moderate to high amounts of physical activity may be associated with reduced risk of influenza for individuals <65 years. Future research should use laboratory-confirmed influenza outcomes to confirm the association between physical activity and influenza. PMID:22737242

The Research Prioritization Task Force of the National Action Alliance for Suicide Prevention conducted a stakeholder survey including 716 respondents from 49 U.S. states and 18 foreign countries. To conduct a qualitative analysis on responses from individuals representing four main stakeholder groups: attempt and loss survivors, researchers, providers, and policy/administrators. This article focuses on a qualitative analysis of the early-round, open-ended responses collected in a modified online Delphi process, and, as an illustration of the research method, focuses on analysis of respondents' views of the role of life and emotional skills in suicide prevention. Content analysis was performed using both inductive and deductive code and category development and systematic qualitative methods. After the inductive coding was completed, the same data set was re-coded using the 12 Aspirational Goals (AGs) identified by the Delphi process. Codes and thematic categories produced from the inductive coding process were, in some cases, very similar or identical to the 12 AGs (i.e., those dealing with risk and protective factors, provider training, preventing reattempts, and stigma). Other codes highlighted areas that were not identified as important in the Delphi process (e.g., cultural/social factors of suicide, substance use). Qualitative and mixed-methods research are essential to the future of suicide prevention work. By design, qualitative research is explorative and appropriate for complex, culturally embedded social issues such as suicide. Such research can be used to generate hypotheses for testing and, as in this analysis, illuminate areas that would be missed in an approach that imposed predetermined categories on data.

Abstract Objective This study examined the long-term effectiveness of lithium for the treatment of pediatric bipolar disorder within the context of combination mood stabilizer therapy for refractory mania and pharmacological treatment of comorbid psychiatric conditions. Methods Outpatients, ages 7–17 years, meeting American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) diagnostic criteria for bipolar disorder I (BP-I) (manic or mixed) who demonstrated at least a partial response to 8 weeks of open-label treatment with lithium (Phase I) were eligible to receive open-label lithium for an additional 16 weeks (Phase II). Up to two adjunctive medications could be prescribed to patients experiencing residual symptoms of mania or comorbid psychiatric conditions, following a standardized algorithm. Results Forty-one patients received continued open-label long-term treatment with lithium for a mean of 14.9 (3.0) weeks during Phase II. The mean weight-adjusted total daily dose at end of Phase II was 27.8 (6.7) mg/kg/day, with an average lithium concentration of 1.0 (0.3) mEq/L. Twenty-five of the 41 patients (60.9%) were prescribed adjunctive psychotropic medications for residual symptoms. The most frequent indications for adjunctive medications were refractory mania (n=13; 31.7%) and attention-deficit/hyperactivity disorder (ADHD) (n=15; 36.6%). At the end of this phase 28 (68.3%) patients met a priori criteria for response (≥50% reduction from Phase I baseline in Young Mania Rating Scale [YMRS] summary score and a Clinical Global Impressions-Improvement [CGI-I] score of 1 or 2), with 22 (53.7%) considered to be in remission (YMRS summary score≤12 and CGI-Severity score of 1 or 2). These data suggest that patients who initially responded to lithium maintained mood stabilization during continuation treatment, but partial responders did not experience further improvement during Phase II, despite the opportunity to receive adjunctive medications. The most commonly reported (≥20%) adverse events associated with lithium treatment were vomiting, headache, abdominal pain, and tremor. Conclusions Lithium may be a safe and effective longer-term treatment for patients with pediatric bipolar disorder who respond to acute treatment with lithium. Partial responders to acute lithium did not appear to experience substantial symptom improvement during the continuation phase, despite the possibility that adjunctive medications could be prescribed.

This study assessed the impact of kilojoule (kJ) labelling alone or accompanied by a social marketing campaign on food sales and selection of less energy-dense meals by young adults from a university food outlet. There were two kJ labelling intervention phases each of five weeks: (1) kJ labelling alone (2) kJ labels with marketing materials ("8700 kJ campaign"). Food sales of labelled items were tracked during each intervention and five weeks after. Food sales during interventions were also compared with historical sales of foods in the same 10-week period in the previous year. A sub sample of young adults (n = 713; aged 19-24) were surveyed during both the interventions to assess awareness, influence, sentiment and anticipated future impact of kJ labels and the social marketing campaign respectively. There were no differences in sales between the kJ labelling with social marketing and the 5-weeks of labelling before and after. The percentage sale of chicken Caesar burger (3580 kJ, P = 0.01), steak and chips (4000 kJ, P = 0.02) and the grill burger (5500 kJ, P = 0.00) were lower in the year with menu labelling and social marketing campaign. Only 30 % students were initially aware of the kJ labels on the menu but 75 % of students were accepting of kJ labelling, after they were made aware. Respondents viewing the marketing campaign elements and then using kJ values on the menu selected meals with a lower mean energy content; constituting a reduction of 978 kJ (p < 0.01) even though the majority claimed that the 8700 kJ campaign would not impact their food choices. Point-of-purchase energy labelling may be an effective method to encourage better food choices when eating out among young adults. However, further efforts to increase awareness and provide education about energy requirements to prevent weight gain will be needed.

Isotope-coded ESI-enhancing derivatization reagents for differential analysis, quantification and profiling of metabolites in biological samples by LC/MS: A review.

The analysis of the qualitative and quantitative changes of metabolites in body fluids and tissues yields valuable information for the diagnosis, pathological analysis and treatment of many diseases. Recently, liquid chromatography/electrospray ionization-(tandem) mass spectrometry [LC/ESI-MS(/MS)] has been widely used for these purposes due to the high separation capability of LC, broad coverage of ESI for various compounds and high specificity of MS(/MS). However, there are still two major problems to be solved regarding the biological sample analysis; lack of sensitivity and limited availability of stable isotope-labeled analogues (internal standards, ISs) for most metabolites. Stable isotope-coded derivatization (ICD) can be the answer for these problems. By the ICD, different isotope-coded moieties are introduced to the metabolites and one of the resulting derivatives can serve as the IS, which minimize the matrix effects. Furthermore, the derivatization can improve the ESI efficiency, fragmentation property in the MS/MS and chromatographic behavior of the metabolites, which lead to a high sensitivity and specificity in the various detection modes. Based on this background, this article reviews the recently-reported isotope-coded ESI-enhancing derivatization (ICEED) reagents, which are key components for the ICD-based LC/MS(/MS) studies, and their applications to the detection, identification, quantification and profiling of metabolites in human and animal samples. The LC/MS(/MS) using the ICEED reagents is the powerful method especially for the differential analysis (relative quantification) of metabolites in two comparative samples, simultaneous quantification of multiple metabolites whose stable isotope-labeled ISs are not available, and submetabolome profiling.

Tomato plants homozygous for the diageotropica (dgt) mutation exhibit morphological and physiological abnormalities which suggest that they are unable to respond to the plant growth hormone auxin (indole-3-acetic acid). The photoaffinity auxin analog [3H]5N3-IAA specifically labels a polypeptide doublet of 40 and 42 kilodaltons in membrane preparations from stems of the parental variety, VFN8, but not from stems of plants containing the dgt mutation. In roots of the mutant plants, however, labeling is indistinguishable from that in VFN8. These data suggest that the two polypeptides are part of a physiologically important auxin receptor system, which is altered in a tissue-specific manner in the mutant.

Phase sensitive spectral domain interferometry for label free biomolecular interaction analysis and biosensing applications

NASA Astrophysics Data System (ADS)

Chirvi, Sajal

Biomolecular interaction analysis (BIA) plays vital role in wide variety of fields, which include biomedical research, pharmaceutical industry, medical diagnostics, and biotechnology industry. Study and quantification of interactions between natural biomolecules (proteins, enzymes, DNA) and artificially synthesized molecules (drugs) is routinely done using various labeled and label-free BIA techniques. Labeled BIA (Chemiluminescence, Fluorescence, Radioactive) techniques suffer from steric hindrance of labels on interaction site, difficulty of attaching labels to molecules, higher cost and time of assay development. Label free techniques with real time detection capabilities have demonstrated advantages over traditional labeled techniques. The gold standard for label free BIA is surface Plasmon resonance (SPR) that detects and quantifies the changes in refractive index of the ligand-analyte complex molecule with high sensitivity. Although SPR is a highly sensitive BIA technique, it requires custom-made sensor chips and is not well suited for highly multiplexed BIA required in high throughput applications. Moreover implementation of SPR on various biosensing platforms is limited. In this research work spectral domain phase sensitive interferometry (SD-PSI) has been developed for label-free BIA and biosensing applications to address limitations of SPR and other label free techniques. One distinct advantage of SD-PSI compared to other label-free techniques is that it does not require use of custom fabricated biosensor substrates. Laboratory grade, off-the-shelf glass or plastic substrates of suitable thickness with proper surface functionalization are used as biosensor chips. SD-PSI is tested on four separate BIA and biosensing platforms, which include multi-well plate, flow cell, fiber probe with integrated optics and fiber tip biosensor. Sensitivity of 33 ng/ml for anti-IgG is achieved using multi-well platform. Principle of coherence multiplexing for multi-channel label-free biosensing applications is introduced. Simultaneous interrogation of multiple biosensors is achievable with a single spectral domain phase sensitive interferometer by coding the individual sensograms in coherence-multiplexed channels. Experimental results demonstrating multiplexed quantitative biomolecular interaction analysis of antibodies binding to antigen coated functionalized biosensor chip surfaces on different platforms are presented.

Obesity is an enormous public health problem and children have been particularly highlighted for intervention. Of notable concern is the fast-food consumption of children . However, we know very little about how children or their parents make fast-food choices, including how they respond to mandatory calorie labeling. We examined children's and adolescents' fast-food choice and the influence of calorie labels in low-income communities in New York City (NYC) and in a comparison city (Newark, NJ). Natural experiment: Survey and receipt data were collected from low-income areas in NYC, and Newark, NJ (as a comparison city), before and after mandatory labeling began in NYC. Study restaurants included four of the largest chains located in NYC and Newark: McDonald's, Burger King, Wendy's and Kentucky Fried Chicken. A total of 349 children and adolescents aged 1-17 years, who visited the restaurants with their parents (69%) or alone (31%) before or after labeling was introduced. In total, 90% were from racial or ethnic minority groups. We found no statistically significant differences in calories purchased before and after labeling; many adolescents reported noticing calorie labels after their introduction (57% in NYC) and a few considered the information when ordering (9%). Approximately 35% of adolescents ate fast food six or more times per week and 72% of adolescents reported that taste was the most important factor in their meal selection. Adolescents in our sample reported that parents have some influence on their meal selection. Adolescents in low-income communities notice calorie information at similar rates as adults, although they report being slightly less responsive to it than adults. We did not find evidence that labeling influenced adolescent food choice or parental food choices for children in this population.

In order to gain insight into the molecular mechanisms that allow taste cells to respond to changes in their osmotic environment, we have used primarily immunocytochemical and molecular approaches to look for evidence of the presence of aquaporin-like water channels in taste cells. Labeling of isolated taste buds from the fungiform, foliate, and vallate papillae in rat tongue with antibodies against several of the aquaporins (AQPs) revealed the presence of AQP1, AQP2, and AQP5 in taste cells from these areas. AQP3 antibodies failed to label isolated taste buds from any of the papillae. There was an apparent difference in the regional localization of AQP labeling within the taste bud. Antibodies against AQP1 and AQP2 labeled predominantly the basolateral membrane, whereas the AQP5 label was clearly evident on both the apical and basolateral membranes of cells within the taste bud. Double labeling revealed that AQP1 and AQP2 labeled many, but not all, of the same taste cells. Similar double-labeling experiments with anti-AQP2 and anti-AQP5 clearly showed that AQP5 was expressed on or near the apical membranes whereas AQP2 was absent from this area. The presence of these 3 types of AQPs in taste buds but not in non-taste bud-containing epithelia was confirmed using reverse transcription-polymerase chain reaction. Experiments using patch clamp recording showed that the AQP inhibitor, tetraethylammonium, significantly reduced hypoosmotic-induced currents in rat taste cells. We hypothesize that the AQPs may play roles both in the water movement underlying compensatory mechanisms for changes in extracellular osmolarity and, in the case of AQP5 in particular, in the gustatory response to water.

S-nitrosylation (SNO), an oxidative post-translational modification of cysteine residues, responds to changes in the cardiac redox-environment. Classic biotin-switch assay and its derivatives are the most common methods used for detecting SNO. In this approach, the labile SNO group is selectively replaced with a single stable tag. To date, a variety of thiol-reactive tags have been introduced. However, these methods have not produced a consistent data set, which suggests an incomplete capture by a single tag and potentially the presence of different cysteine subpopulations. To investigate potential labeling bias in the existing methods with a single tag to detect SNO, explore if there are distinct cysteine subpopulations, and then, develop a strategy to maximize the coverage of SNO proteome. We obtained SNO-modified cysteine data sets for wild-type and S-nitrosoglutathione reductase knockout mouse hearts (S-nitrosoglutathione reductase is a negative regulator of S-nitrosoglutathione production) and nitric oxide-induced human embryonic kidney cell using 2 labeling reagents: the cysteine-reactive pyridyldithiol and iodoacetyl based tandem mass tags. Comparison revealed that <30% of the SNO-modified residues were detected by both tags, whereas the remaining SNO sites were only labeled by 1 reagent. Characterization of the 2 distinct subpopulations of SNO residues indicated that pyridyldithiol reagent preferentially labels cysteine residues that are more basic and hydrophobic. On the basis of this observation, we proposed a parallel dual-labeling strategy followed by an optimized proteomics workflow. This enabled the profiling of 493 SNO sites in S-nitrosoglutathione reductase knockout hearts. Using a protocol comprising 2 tags for dual-labeling maximizes overall detection of SNO by reducing the previously unrecognized labeling bias derived from different cysteine subpopulations. © 2015 American Heart Association, Inc.

Several countries have proposed changes to calorie labelling on nutrition facts tables (NFTs) on pre-packaged foods. As most research to date has examined general use of NFTs, there is a lack of evidence to guide specific design changes to calorie information on labels. This study examined the efficacy of various calorie labelling formats on recall, comprehension, and consumer preferences for calorie information. Experiments were conducted as part of an online survey with a national sample of 2,008 Canadians aged 16-24. In Task 1, participants were shown one of six labelling formats (e.g., %DV, Traffic Light) with calories in either small or large font, and asked to recall the amount of calories. Task 2 examined comprehension of calories in the context of recommended daily intake (RDI), using the same NFT as in Task 1. Task 3 identified participants' preferences for labelling formats. NFTs with calories in large font enhanced calorie recall (p < 0.001). When small font was displayed, the Traffic Light format performed best at improving recall (p < 0.01). With large font, the highest recall was in the Current, RDI and Traffic Light formats (all p < 0.05). Comprehension of servings per RDI was highest in the Infographic format, with no difference by font size (p < 0.001). Respondents preferred the large font calorie condition and the Infographic format (p < 0.001). Enhancements in visibility and design can improve the efficacy of calorie labelling on pre-packaged foods. The findings have direct implication for proposed changes to calorie labelling on NFTs in Canada and the United States.

This cross-sectional, community-based study was carried out among commercial motorcyclists in Igboora. All the commercial motor parks in Igboora were visited and all the commercial motorcyclists who consented to participate in the study were interviewed. Information on the respondents' socio-demographic characteristics, and the practice of road safety measures was collected using an interviewer administered questionnaire. A total of 299 motorcyclists were interviewed. All (100%) of them were males. The mean age of the respondents was 27.4 +/- 7.4 years. One hundred eighty-two (60.7%) of the motorcyclists had the correct knowledge of the purpose of Highway Code. Only 70 (23.3%) could recognize more than half of the currently used road safety codes and 47 (15.7%) obey these road safety codes more than half of the time they see it. Only 183 (61.2%) of them had a driving license and 72 (24.1%) were able to produce these licenses on demand. All (100%) of the respondents did not use any protective helmet. Those who have longer years of working experience, higher level of education and higher knowledge of the safety codes practice it more regularly (r = 0.198, p = 0.001, chi2= 9.31, p = 0.025, and r = 0.28, p = 0.001 respectively). One hundred thirty-six (45.5%) have been involved in at least one accident in the preceding year. The overall incidence of road traffic accident was 2.16 per 1,000. There was however on statistically significant association between the practice of road safety codes and the occurrence of road traffic accidents (chi2= 0.176, p = 0.916). The study shows that the practice of road safety measures was low in this rural Nigerian community and was not associated with the incidence of road traffic accidents. Introducing road safety education particularly targeted at educating the motorcyclists on the importance and practice of road safety measures would lead to an increase in the practice of the safety measures and hopefully a reduction in the incidence of road traffic accidents.
