Consumer Health Informatics: An Overview of Patient Perspectives on Health Information Needs
Authors: Dey Aditi 
Published: March 2016

Patients are increasingly expressing their need for more information about their health. Different healthcare professionals provide a range of information to their patients during delivery of care. By means of a detailed literature search and a study of available evidence, this article explores patients' perspectives in gaining health-related information from the healthcare system, with particular emphasis on patients who come in contact with breast cancer services. The literature review indicates that the main issues concerning health information available to consumers can be divided into the following sections: quantity of information (amount of information, number of sources, types and strategies for distribution); quality of information (validity, relevance, accessibility, understandability, timing of acquisition); and consumer/patient factors (age, health status, empowerment to make decisions). Information-seeking behaviour of consumers should be considered as part of a broader environmental and role-related context. The acquisition of information and the decision to seek information (either personally or using the help or services of other people) is affected by stress, perception of risk, hope for reward and perceived level of self-efficacy.
Continuous Glucose Monitoring in Type 1 Diabetes
Authors: Borges Uirassu , Kubiak Thomas 
Published: March 2016

Background: Continuous glucose monitoring (CGM) patient systems have been shown to improve diabetes self-treatment when used consistently. The meaningful integration of this technology into everyday life, however, can vary greatly among CGM users and not all people with diabetes use CGM to its full potential. To address this issue, the study pursued 2 aims: first, to identify patient characteristics that underlie the acceptance of CGM in people with type 1 diabetes and, second, to examine the effects of different levels of experience with CGM use. Methods: Guided by a model based on the technology acceptance model (TAM), structural equation modeling (SEM) was employed to model the patient characteristics as predictors of CGM acceptance. In all, 111 participants (60.4% female, mean = 37.6 years, SD = 11.2) participated in a web-based survey; 40 were current CGM users, 18 were former users and 53 had no experience with CGM systems. Results: In general, participants evaluated CGM positively; however, the feeling of information overload represented a major barrier to the sustained use of CGM, while perceptions of usefulness and ease of use constituted incentives for using this technology. Moreover, patients without CGM experience imagined more information overload than current users reported. Current users showed more intention to use CGM than former users. Conclusion: This study highlights the importance of CGM user experience for the effective use of this technology.
Recurrent Endocrine Cycles

Published: March 2016

Background: The chaotic nature of blood glucose creates a formidable clinical challenge for diabetes healthcare. The recent discovery of recurrent endocrine cycles offers the advantage of advanced-prediction (proactive) health care. Methods: Historical studies covering 111 patients and 1 subject collected several months of glucose readings and their daily metrics. Phase portraits and phase analytics can detect recurrent metric cycles and test their ability to anticipate serious glycemic conditions. Results: Recurrent patterns were detected having a rate of ~7 days per complete cycle. Plots and risk models based on these cycles produced advanced alerts for acute glycemia, capturing greater than 96% of true-positive days with a 5% false-positive rate. Conclusions: This method can be implemented graphically and functionally within a BG monitoring system to warn doctors and patients of impending serious glycemic levels.

Purpose Debate on adjunct screening in women with dense breasts has followed legislation requiring that women be informed about their mammographic density and related adjunct imaging. Ultrasound or tomosynthesis can detect breast cancer (BC) in mammography-negative dense breasts, but these modalities have not been directly compared in prospective trials. We conducted a trial of adjunct screening to compare, within the same participants, incremental BC detection by tomosynthesis and ultrasound in mammography-negative dense breasts. Patients and Methods Adjunct Screening With Tomosynthesis or Ultrasound in Women With Mammography-Negative Dense Breasts is a prospective multicenter study recruiting asymptomatic women with mammography-negative screens and dense breasts. Eligible women had tomosynthesis and physician-performed ultrasound with independent interpretation of adjunct imaging. Outcome measures included cancer detection rate (CDR), number of false-positive (FP) recalls, and incremental CDR for each modality; these were compared using McNemar’s test for paired binary data in a preplanned interim analysis. Results Among 3,231 mammography-negative screening participants (median age, 51 years; interquartile range, 44 to 78 years) with dense breasts, 24 additional BCs were detected (23 invasive): 13 tomosynthesis-detected BCs (incremental CDR, 4.0 per 1,000 screens; 95% CI, 1.8 to 6.2) versus 23 ultrasound-detected BCs (incremental CDR, 7.1 per 1,000 screens; 95% CI, 4.2 to 10.0), P = .006. Incremental FP recall occurred in 107 participants (3.33%; 95% CI, 2.72% to 3.96%). FP recall (any testing) did not differ between tomosynthesis (FP = 53) and ultrasound (FP = 65), P = .26; FP recall (biopsy) also did not differ between tomosynthesis (FP = 22) and ultrasound (FP = 24), P = .86. Conclusion The Adjunct Screening With Tomosynthesis or Ultrasound in Women With Mammography-Negative Dense Breasts’ interim analysis shows that ultrasound has better incremental BC detection than tomosynthesis in mammography-negative dense breasts at a similar FP-recall rate. However, future application of adjunct screening should consider that tomosynthesis detected more than 50% of the additional BCs in these women and could potentially be the primary screening modality.

Published: March 2016

Purpose In Honduras, the breast cancer burden is high, and access to women’s health services is low. This project tested the connection of community-based breast cancer detection with clinical diagnosis and treatment in a tightly linked and quickly facilitated format. Methods The Norris Cotton Cancer Center at Dartmouth College partnered with the Honduran cancer hospital La Liga Contra el Cancer to expand a cervical cancer screening program, which included self-breast exam (SBE) education and clinical breast exams (CBEs), to assess patient attitudes about and uptake of breast cancer education and screening services. The cervical cancer screening event was held in Honduras in 2013; 476 women from 31 villages attended. Results Half of the women attending elected to receive a CBE; most had concerns about lactation. Clinicians referred 12 women with abnormal CBEs to La Liga Contra el Cancer for additional evaluation at no cost. All referred patients were compliant with the recommendation and received follow-up care. One abnormal follow-up mammogram/ultrasound result was negative on biopsy. One woman with an aggressive phyllodes tumor had a mastectomy within 60 days. Multimodal education about breast cancer screening maximized delivery of women’s health services in a low-tech rural setting. Conclusion The addition of opportunistic breast cancer education and screening to a cervical cancer screening event resulted in high uptake of services at low additional cost to program sponsors. Such novel strategies to maximize delivery of women’s health services in low-resource settings, where there is no access to mammography, may result in earlier detection of breast cancer. Close follow-up of positive results with referral to appropriate treatment is essential.
NGT-3D: a simple nematode cultivation system to studyCaenorhabditiselegansbiology in 3D
Authors: Lee Tong Young , Yoon Kyoung-hye , Lee Jin Il 
Published: March 2016

ABSTRACTThe nematode Caenorhabditiselegans is one of the premier experimental model organisms today. In the laboratory, they display characteristic development, fertility, and behaviors in a two dimensional habitat. In nature, however, C. elegans is found in three dimensional environments such as rotting fruit. To investigate the biology of C. elegans in a 3D controlled environment we designed a nematode cultivation habitat which we term the nematode growth tube or NGT-3D. NGT-3D allows for the growth of both nematodes and the bacteria they consume. Worms show comparable rates of growth, reproduction and lifespan when bacterial colonies in the 3D matrix are abundant. However, when bacteria are sparse, growth and brood size fail to reach levels observed in standard 2D plates. Using NGT-3D we observe drastic deficits in fertility in a sensory mutant in 3D compared to 2D, and this defect was likely due to an inability to locate bacteria. Overall, NGT-3D will sharpen our understanding of nematode biology and allow scientists to investigate questions of nematode ecology and evolutionary fitness in the laboratory.

themselves, this structure lives over X and allows for a convenient notion of global convergence as well as the appropriate background structure for doing analysis on X. This structure is new even in the case of uniformly bounded curvature and as an application we give a generalization of Gromov’s Almost Flat Theorem and prove new Ricci pinching theorems which extend those known in the noncollapsed setting. There are also interesting topological consequences to the structure.
Prediction of the Shoppers Loyalty with Aggregated Data Streams
Authors: Nikulin Vladimir 
Published: March 2016

Abstract
Consumer brands often offer discounts to attract new shoppers to buy their products. The most valuable customers are those who return after this initial incentive purchase. With enough purchase history, it is possible to predict which shoppers, when presented an offer, will buy a new item. While dealing with Big Data and with data streams in particular, it is a common practice to summarize or aggregate customers’ transaction history to the periods of few months. As an outcome, we compress the given huge volume of data, and transfer the data stream to the standard rectangular format. Consequently, we can explore a variety of practically or theoretically motivated tasks. For example, we can rank the given field of customers in accordance to their loyalty or intension to repurchase in the near future. This objective has very important practical application. It leads to preferential treatment of the right customers. We tested our model (with competitive results) online during Kaggle-based Acquire Valued Shoppers Challenge in 2014.

Published: March 2016

Abstract
Technological advancements within the educational sector and online learning promoted portable data-based adaptive techniques to influence the developments within transformative learning and enhancing the learning experience. However, many common adaptive educational systems tend to focus on adopting learning content that revolves around pre-black box learner modelling and teaching models that depend on the ideas of a few experts. Such views might be characterized by various sources of uncertainty about the learner response evaluation with adaptive educational system, linked to learner reception of instruction. High linguistic uncertainty levels in e-learning settings result in different user interpretations and responses to the same techniques, words, or terms according to their plans, cognition, pre-knowledge, and motivation levels. Hence, adaptive teaching models must be targeted to individual learners’ needs. Thus, developing a teaching model based on the knowledge of how learners interact with the learning environment in readable and interpretable white box models is critical in the guidance of the adaptation approach for learners’ needs as well as understanding the way learning is achieved.
This paper presents a novel interval type-2 fuzzy logic-based system which is capable of identifying learners’ preferred learning strategies and knowledge delivery needs that revolves around characteristics of learners and the existing knowledge level in generating an adaptive learning environment. We have conducted a large scale evaluation of the proposed system via real-word experiments on 1458 students within a massively crowded e-learning platform. Such evaluations have shown the proposed interval type-2 fuzzy logic system’s capability of handling the encountered uncertainties which enabled to achieve superior performance with regard to better completion and success rates as well as enhanced learning compared to the non-adaptive systems, adaptive system versions led by the teacher, and type-1-based fuzzy based counterparts.

Published: March 2016

Abstract
Background: This study draws upon the use of Information Systems in support of achieving sustainability, known as Green IS. Furthermore, this study builds on the premise that Green IS offers the opportunity for organizations to act proactively in terms of environmental preservation as well as to mitigate the effects of global climate change and other environmental problems.
Aim: In particular, this study aims to assess the extent of awareness among managers regarding the use and the acceptance of Green IS in Slovenian enterprises.
Method: Using empirical data based on a large-scale survey among senior managers within Slovenian enterprises this study utilized several statistical methods (such as t-test, analysis of variance and multiple linear regression) to analyse the research questions.
Results: In general, findings seem to suggest that institutional mechanisms might be a plausible explanation for differences regarding the attitude towards Green IS adoption. For instance, enterprises with at least one implemented sustainability related certificate expressed higher levels of willingness to use Green IS in order to facilitate the achievement of sustainable development. Moreover, the results of the regression analysis revealed that both Institutional Mimetic pressure and Internal Environment Impact has positive impact on Green IS adoption.
Conclusion: The main conclusion is that the internal environmental impact is considered the most influential factor of the attitude towards Green IS adoption. The culture or individual perception of managers and employees play an important role in the Green IS adoption. Indeed, enterprises that have no intention of improving their environmental performance, but adopt Green IS by the means of seeking legitimacy among external stakeholders, cannot provide a sustainable improvement in environmental management.

Abstract
This paper integrates dispersive optical solitons in special optical metamaterials with a time dependent coefficient. We obtained some optical solitons of the aforementioned equation. It is shown that the examined dependent coefficients are affected by the velocity of the wave. The first integral method (FIM) and ansatz method are applied to reach the optical soliton solutions of the one-dimensional nonlinear Schrödinger’s equation (NLSE) with time dependent coefficients.

Zusammenfassung:
Wie in mehreren Untersuchungen gezeigt wurde, ist die bevölkerungsbezogene Morbidität und damit auch die Inanspruchnahme medizinischer Leistungen mit dem Ausmaß räumlicher sozialer Deprivation assoziiert. Der vorliegende Beitrag zeigt darüber hinaus, dass auch der Grad an Urbanität als bisher nicht beachtetes sozioregionales Merkmal bei der Beurteilung von bedarfsgerechter Versorgung berücksichtigt werden sollte.
Regionale Versorgungsunterschiede
Authors: Sundmacher Leonie 
Published: March 2016

Zusammenfassung:
Die Darstellung von Versorgungsunterschieden oder Krankheitsraten in einer Karte erlaubt die Beurteilung des Ausmaßes der Variationen und die Identifikation von regionalen Clustern. Aber ohne eine theoriegeleitete Auswahl und Analyse der regionalen Variationen, kann keine Aussage darüber getroffen werden, wie Variationen entstehen oder ob diese ungewollt sind oder nicht. Ein differenziertes Bild ergibt sich, wenn man drei Kategorien von Versorgung unterscheidet, deren Variationen unterschiedliche, theoriegeleitete Interpretationen zulassen: Effektive Versorgung (effective care), angebotssensitive Versorgung (supply-sensitive care) und präferenzsensitive Versorgung (preference sensitive care). Neben effektiver, angebots- und präferenzsensitiver Versorgung existieren in der Literatur zudem Konzepte, die auf die regionale Analyse sogenannter versorgungssensitiver Gesundheitsergebnisse abzielen. Der kurze Artikel führt in die grundlegenden Theorien zur Analyse von Versorgungsunterschieden ein. Der folgende Beitrag ist ein kurzer Auszug aus dem Artikel „Regionale Variationen in Gesundheit und Gesundheitsversorgung“, erschienen in dem Lehrbuch „Soziologie von Gesundheit und Krankheit“ (Sundmacher L. Regionale Variationen in Gesundheit und Gesundheitsversorgung. In: Richter M, Hurrelmann K, editors. Soziologie von Gesundheit und Krankheit. Wiesbaden: Springer VS, 2016: 197–209.).

Zusammenfassung:
Die Integrierte Versorgung Gesundes Kinzigtal (IVGK) ist eine regionale integrierte Vollversorgung und wird umfassend extern evaluiert. In einer kontrollierten Längsschnittstudie wird anhand von GKV-Routinedaten untersucht, wie sich die Versorgungsqualität in der Region Kinzigtal im Vergleich zu einer Kontrollgruppe aus dem restlichen Baden-Württemberg entwickelt. Hierfür wurden insgesamt 37 Kennziffern gebildet. An drei Beispielen zeigen wir, dass die Eignung einer Kennziffer als Qualitätsindikator und Endpunkt regional vergleichender Studien sehr voraussetzungsvoll ist.

Influence of aggregate gradation on hma mixes stability
Authors: Kalaitzaki Elvira , Kollaros George , Athanasopoulou Antonia 
Published: March 2016

Abstract
The load transfer capacity of pavements is to a great extend influenced by aggregates. About 85% of the total volume of hot mix asphalt (HMA) mixtures consists of aggregates; thus, they are greatly influenced by aggregate properties like angularity (shape), roughness (texture), and gradation. Aggregate gradation controls the structure of voids. Current specifications for aggregate properties in HMA pavements require the aggregate blend to fall within a specified range of gradation values. Although the abovementioned requirement has ensured the construction of high quality HMA pavements, the properties are largely empirical and they are not based on performance-related tests. Marshall Stability is in principle the resistance to plastic flow of cylindrical specimens of a bituminous mixture loaded on the lateral surface. It is the load carrying capacity of the mix at 60oC. Aggregates with different gradations from the broader area of Xanthi, Northern Greece, have been used to prepare specimens for stability testing of hot asphalt mixtures in the laboratory. The research focused on the evaluation of the influence of aggregates in the overall stability characteristics of the mixtures. The maximum stability value has been obtained with an open-graded mixture having 5% asphalt and aggregate size 2.36 mm. However, the stability of the dense graded mixture is higher than this maximum value.
