Investigation of challenges and opportunities for the adoption of cloud-based Internet of things (IoT) in Australian agricultural SME
Authors: Sandu Nitirajsingh , Gide Ergun
Published: December 2018

Increasing adoption of the Internet of things (IoT) is bringing revolutionary changes in the agricultural, manufacturing, retailing and finance industries, as they improve the existing business processes and reduce cost. IoT is seen as a powerful tool for agricultural SMEs in Australia, with the potential to transform farming and food production into a smart web of interconnected objects and, thus, improve the general productivity and sustainability of the food chain. However, as some of the innovative solutions may need to store the data locally on the device, and mostly on the cloud, it raises serious privacy and regulatory concerns. This paper used a pilot online survey to investigate the challenges and opportunities for adoption of IoT for Australian SMEs in agriculture and it is expected that it will help application and solution providers to address any issues that may arise in the Australian scenario.

 

Keywords: Internet of things, cloud systems, small-to-medium enterprises, adoption issue, agriculture, Australia.
Barriers to adopting e-commerce with small to mid-sized enterprises-SMEs in developed countries: an exploratory study in Australia
Authors: Karim Shakir , Gide Ergun
Published: December 2018

This paper aims to provide an insight about barriers affecting e‐commerce adoption with small to mid-sized enterprise—small and medium enterprises (SMEs) in Australia. The objective of this research is also to consolidate the factors and determine the level of influence, either positively or negatively from the adopter’s perspective, on the adoption decision. This study also examines the factors influencing e-commerce adoption decisions in SMEs in Australia. The finding says that one of the most vivid implications of e-commerce for SMEs is the potential for external communication and information gathering for market and product research. The study has found that the historical relationship problems between the business link and SMEs are still causing problems. The findings also show that in Australia, organisations and manager’s characteristics, perceived benefits, organisational culture, organisational IT competence, technological competency, IT support, availability of financial support, management commitment/support, external pressure and cost of adoption are significant predictors of e-commerce acceptance in the SMEs and have significant relationships with e commerce adoption in Australia.

Published: December 2018

This study aims to examine the quality of frozen semen in Tris egg yolk (TEY) extender and skimmed milk extender with or witout omega-3. A total of 18 Simmental bulls belong to Lembang Artificial Insemination Centre were divided into three groups. Each was fed with standard feed (R1), standard feeds supplemented with minimal Se and Zn (R2) and standard feed supplemented with maximal of Se and Zn concentration. Semen were collected using an artificial vagina and were evaluated macro- and microscopically. The semen then were divided into four tubes and each diluted with Skimmed, SkimmedOmega 3, TEY or TEY-O. The semen was then packed into a 0.25 ml straw and equilibrated at 5 oC for 4 hours, then frozen above liquid nitrogen vapor, and stored in liquid nitrogen container (-196 oC). The qualities of frozen semen were evaluated on the motility, individual score, viability and integrity of the plasma membrane of sperms. Sperm motility of bulls fed with standard feed (R1) in TEY extender and R3 in TEY and TEY-Omega-3 extender were higher (p <0.05) compared to the other combinations. No difference was found on the individual score. The viability of sperms in bulls fed with standard feed in SkimmedOmega-3 extender was higher than the other treatments and the highest sperm plasma membrane integrity was demonstrated by sperm in bull feeding with R2 in TEY extender.

Diana’s Diabetes by W. J. Hall
Authors: Eke Victoria
Published: December 2018

Hall, Wendy J. Diana’s Diabetes. CreateSpace Independent Publishing Platform, 2018.

As part of the Mediwonderland book series designed to “guide children through common medical procedures and illnesses”, Diana’s Diabetes follows the journey of Diana, a young girl recently diagnosed with Type 1 diabetes, as she learns about her condition and how it is managed.

Following the identification of symptoms and her initial diagnosis, Diana and her mother return to the clinic for an information session and follow-up with Dr. Daniel and Nurse Nina. There, Diana and her mother learn about the mechanics of the illness, self-monitoring for blood glucose, and insulin injections. Diana is also given a journal in which she must record her food intake and insulin doses, as well as a medical identification bracelet.

Major concepts are introduced through text and accompanying illustrations. The text, printed in large font, is easy to read. The content is rolled out logically, allowing for one concept to build upon the previous. Colourful illustrations by Ysha Morco serve to complement the text, providing visuals for the various concepts presented. However, in the case of the “Type 1 Diabetes” poster illustrated on pages 15 and 16, more detail and additional labels could have been added to better explain the biology behind the illness.

In addition to providing an informative and factually sound overview of Type 1 diabetes in children, author Wendy J. Hall has successfully created characters and a scenario that will undoubtedly resonate with patients and family members alike, serving as both a source of information and comfort.

This book is highly recommended for public, elementary school, and children’s hospital libraries.

West Coast ABCs by J. Asnong
Authors: MacLeod Lorisia
Published: December 2018

Asnong, Jocey. West Coast ABCs. Rocky Mountain Books, 2018.

Jocey Asnong returns with a new ABC book similar to her Rocky Mountain ABCs but this time highlights the beautiful west coast of Canada. Each page of this board book features one or two letters from the alphabet, a west coast place starting with one of those letters, a full colour illustration relating to that place, and a short phrase using words beginning with the alphabet letter(s) of the page. The target audience for this work would include toddlers, pre-K, and early primary students. Some of the words might be difficult for younger readers so this is a book best read with an adult though even the youngest readers will love the bright colours of the illustrations.

Since most of the letters have more than one word, this book better represents some of the different sounds that each letter can make, for example the sounds in paddle versus porpoises which makes this book particularly attractive for anyone working on phonetics with a reader. I would especially recommend this for anyone on the west coast as having familiar places featured in the book would only increase the enjoyment already provided by the wonderful art showcased in this work.

Sleep Disorders as a Mediator Between Socioeconomic Status and Health Outcomes: A Review of Differents Theories
Authors: Etindele Sosso Faustin Armel , Papadopoulos Dimitrios
Published: December 2018

The variations in socioeconomic status (SES) between different social classes of a population correspond to differences in accessibility to all resources available and able to improve global health. While SES is now known as one of the main determinants for a good health and a good aging, its influence on sleep disorders (SD) is not well understood. SES is a concept, not directly observable but estimated using indicators like income, education, occupational status and area of living. This theoretical review explores some theories linking environment of people with occurrence of SD, with different patterns associated to SES. A model of interaction is proposed to summarize and conceptualizes these interactions and to promote more research on the topic.
A Scheme for Ultrasensitive Detection of Molecules with Vibrational Spectroscopy in Combination with Signal Processing
Authors: Tan Yong Boon , Tay Rongde Ian , Loy Liang Yi , Aw Ke Fun , Ong Zhi Li , Manzhos Sergei
Published: December 2018

We show that combining vibrational spectroscopy with signal processing can result in a scheme for ultrasensitive detection of molecules. We consider the vibrational spectrum as a signal on the energy axis and apply a matched filter on that axis. On the example of a nerve agent molecule, we show that this allows detecting a molecule by its vibrational spectrum even when the recorded spectrum is completely buried in noise, when conventional spectroscopic detection is impossible. Detection is predicted to be possible with signal-to-noise ratios in recorded spectra as low as 0.1. We study the importance of spectral range used for detection as well as of the quality of the computed spectrum used to program the filter, specifically, the role of anharmonicity, of the exchange correlation functional, and of the basis set. The use of the full spectral range rather than of a narrow spectral window with key vibrations is shown to be advantageous, as well as accounting for anharmonicity.
Multi-Points Cooperative Relay in NOMA System with N-1 DF Relaying Nodes in HD/FD mode for N User Equipments with Energy Harvesting
Authors: Tran Thanh-Nam , Voznak Miroslav
Published: December 2018

Non-Orthogonal Multiple Access (NOMA) is the key technology promised to be applied in next-generation networks in the near future. In this study, we propose a multi-points cooperative relaying (MPCR) NOMA model instead of just using a relay as the previous studies. Based on the channel state information (CSI), the base station (BS) selects a closest user equipment (UE) and sends a superposed signal to this UE as a first relay node. We have assumed that there are N UEs in the network and Nth UE, which is farthest from BS, has the poorest quality signal transmitted from the BS compared other UEs. Nth UE received the forwarded signal from N-1 relaying nodes that are UEs with better signal quality. At the ith relaying node, it detect its own symbol by using successive interference cancellation (SIC) and will forward the composite signal to the next closest user, namely i+1th UE, and include an excess power which will use for energy harvesting (EH) intention at the next UE. By these, the farthest UE in network can be significantly improved. In addition, closed-form expressions of outage probability for users over both the Rayleigh and Nakagami-m fading channels are also presented. Analysis and simulation results performed by Matlab software which are presented accurately and clearly show that the effectiveness of our proposed model and this model consistents with the multi-access wireless network in future.
Concordant and Discordant Construct-Context Dualities as a Framework for Understanding the Choice of Vocational Educational Philosophy of Booker T. Washington
Authors: Carroll La Shun L.
Published: December 2018

This paper explores the rationale behind Booker T. Washington’s vocationalist philosophy of education for the then recently emancipated black population.  Through the use of a critical thinking framework, an analysis of remarks from key speeches and his life according to scholars providing Washington’s prescriptive argument and rhetoric is undertaken. Despite Washington’s intentions, the argument for his vocational approach is demonstrated to be oppressive, myopic, and circular in its logic.  The author proposes a framework for understanding the counterintuitive development of vocationalist philosophy based on the dichotomous nature of the human experience’s value-construct and context misalignment.  Concordant or discordant dualities that result from misalignment are explained and how to reconcile Washington’s Vocationalism with opposing the philosophy of W.E.B. Du Bois due to equivalence or consistency of values with theoretical constructs is also discussed.

Experiential Learning: the field study trip, a student-centred curriculum.
Authors: Pattacini Laurence
Published: December 2018

Drawing from student-centered learning theories, this paper identifies key issues related to active participation of students, collaboration and independent learning. It draws from the author’s experience of developing and delivering a student-centered curriculum delivered around a field study trip. It explores approaches to active and experiential learning in Higher Education through the various stages of the curriculum development and the identification of the pedagogical benefits. The student-centered curriculum is part of a professional accredited course in Landscape architecture. The Field study trip is an opportunity to actively explore the topics of study in real settings and to learn through hands on experience, which is essential to form professionals confronted with making places through planning and design. More generally the field study trip module is an opportunity to understand how to practically embed experiential learning approaches in Higher Education.  The paper also discusses the merits of field trip to address some issues related to the learning experience and participation in the context of the internationalisation of the students’ cohort.
Google Classroom: An online learning environment to support blended learning
Authors: Beaumont Kizzy
Published: December 2018

Google Classroom is a free web service, providing a collaborative tool allowing users to create virtual classrooms, where by they can post assignments, organise folders, and view documents in real time. Google Classroom was initially adopted by the Student Learning Department at Keele University to create a blended approach to university-wide freestanding academic skills development workshops, providing an online community for students to share and open dialogue around topics discussed during workshops. The aim was to bring students from different faculties together and create a sense of community surrounding enhancement of academic practice. Google Classroom provides an intuitive and accessible interface for both staff and students. From both a student and staff perspective at Keele, feedback was very positive. Students engaged in discussions, answered and posed questions to encourage discussion, and gave feedback on resources. This article will demonstrate how the Student Learning Department at Keele University has used Google Classroom and shared user guidance for colleagues to explore in their own practice.

Functional Modeling of Plant Growth Dynamics
Authors: Xu Yuhang , Qiu Yumou , Schnable James C.
Published: December 2018

Recent advances in automated plant phenotyping have enabled the collection of time series measurements from the same plants of a wide range of traits at different developmental time scales. The availability of time series phenotypic datasets has increased interest in statistical approaches for comparing patterns of change among different plant genotypes and different treatment conditions. Two widely used methods of modeling growth with time are pointwise analysis of variance (ANOVA) and parametric sigmoidal curve fitting. Pointwise ANOVA yields discontinuous growth curves, which do not reflect the true dynamics of growth patterns in plants. In contrast, fitting a parametric model to a time series of observations does capture the trend of growth; however, these models require assumptions regarding the true pattern of plant growth. Depending on the species, treatment regime, and subset of the plant life cycle sampled, these assumptions will not always hold true. We have developed a different approach—functional ANOVA—which yields continuous growth curves without requiring assumptions regarding patterns of plant growth. We compared and validated this approach using data from an experiment measuring the growth of two maize (Zea mays L. ssp. mays) genotypes under two water availability treatments during a 21‐d period. Functional ANOVA enables a nonparametric estimation of the dynamics of changes in plant traits with time without assumptions regarding curve shape. In addition to estimating smooth curves of trait values with time, functional ANOVA also estimates the derivatives of these curves, e.g., growth rates, simultaneously. Using two different subsampling strategies, we demonstrate that this functional ANOVA method enables the comparison of growth curves among plants phenotyped on non‐overlapping days with little reduction in estimation accuracy. This means that functional ANOVA based approaches can allow larger numbers of samples and biological replicates to be scored in a single experiment given fixed amounts of phenotyping infrastructure and personnel.
Optimization of coagulation-flocculation process in the treatment of wastewater from the brick-manufacturing industry
Authors: Oraeki T. , Skouteris G. , Ouki S.
Published: December 2018

Brick manufacturing is a water-intensive industry that uses water, mainly potable, as a major raw material in its production process. It is therefore imperative that the wastewater generated by this industry is effectively treated for reutilization. There is limited study on how wastewater from the brick-manufacturing industry can be sustainably managed. Hence, this study was conducted to optimize treatment of wastewater generated by the brick manufacturing industry, employing coagulation-flocculation techniques. Commercially available flocculants, namely slightly anionic polyacrylamide (nPAM), anionic polyacrylamide (aPAM), cationic polyacrylamide (cPAM) and poly diallyldimethylammonium chloride (PDADMAC) were screened using the jar test procedure. The one-factor-at-a-time (OFAT) method was used to optimize the process. The nPAM gave optimal performance based on turbidity and suspended solids removal. Results of the evaluations showed an optimal dose of 0.8 mg L−1 at a pH range of 7.2–7.4 and mixing speed of 200 rpm for 5 minutes, followed by 50 rpm for 15 minutes. Both turbidity and total suspended solids removal was approximately 98% at the optimal condition. This study has demonstrated that optimized coagulation-flocculation can produce treated water of high quality that can be reused to reduce mains water consumption and hence contribute to the industry's sustainability.

Published: December 2018

Lack of sufficient good quality water to fulfill the rural population's needs in many countries, such as Mexico, has become one of the main issues governments have to cope with to provide adequate living conditions. The situation has worsened due to rainfall pattern variability influenced by climate change. Water harvesting is an ancient practice that provides an additional water supply for different uses. The lack of sufficient readily available decision tools within these environments has hindered adequate decision-making. The computer aid presented in this paper serves the purpose of a decision tool for use in marginal rural areas where a water harvesting system is to be implemented. Input variables are easily obtained and the system has preloaded information for use in the water balance. The interface is user-friendly, enabling users to plug local information in to obtain outputs on which to base a decision. Input variables can be changed as needed to achieve an acceptable output. The system generates rainfall amounts stochastically enabling posterior analysis to be used in terms of designing roof water harvesting under different runoff occurrence probabilities.

Published: December 2018

Inspection of deep tunnel networks is extremely challenging due to their inaccessibility, and them being an unknown and potentially hazardous environment. Unmanned aerial vehicles (UAVs) provide a viable alternative for access, and are unaffected by debris or sewer flow. However, commercial UAVs are designed for high altitude aerial imagery and are not appropriate for short-range detailed imaging of tunnel surfaces. In addition, autonomous flight is usually achieved using GPS, which is not available underground. This paper presents the design and development of a smart UAV platform, Surveyor with Intelligent Rotating Lens (SWIRL), customized for autonomous operation in tunnels. It can capture high resolution images for subsequent image processing, and defect detection and classification. An innovative rotating system enables undistorted imaging of the tunnel's inner circumference surface using a single camera. The proposed location method using limited data resulted in substantial unit weight and power consumption reductions, compared to existing systems, making more than 35 minutes of autonomous flight possible.
Selective MMP-13 Inhibitors: Promising Agents for the Therapy of Osteoarthritis
Authors: Wan Yichao , Li Wei , Liao Zhipeng , Yan Mi , Chen Xuwang , Tang Zilong
Published: December 2018

Osteoarthritis (OA) is an age-related degenerative disease, which is characterized by chronic joint pain, inflammation and the damage of joint cartilage. At present, steroidal drugs and nonsteroidal anti-inflammatory drugs (NSAIDS), selective cyclooxygenase-2 (COX-2) inhibitors, are the first-line drugs for the treatment of OA. However, these drugs could lead to some cardiovascular side effects. Therefore, it is urgent to develop novel agents for the treatment of OA. Matrix metalloproteinase-13 (MMP-13), an important member of matrix metalloproteinases (MMPs) family, plays a vital role by degrading type II collagen in articular cartilage and bone in OA. It is noted that MMP-13 is specially expressed in the OA patients, and not in normal adults. In addition, broadspectrum MMP inhibitors could result in some painful and joint-stiffening side effects, called musculoskeletal syndrome (MSS) in the clinical trials. Thus, developing selective MMP-13 inhibitors is a potential strategy for the therapy of OA. In this review, we summarize the recent progress of selective MMP-13 inhibitors including two subfamilies, namely zinc-binding and non-zinc-binding selective MMP-13 inhibitors.

Authors: Amini Peyman , Kolivand Sedighe , Saffar Hana , Rezapoor Saeed , Motevaseli Elahe , Najafi Masoud , Nouruzi Farzad , Shabeeb Dheyauldeen , Musa Ahmed Eleojo
Published: December 2018

Background:

In this study, we aimed to detect the changes in the level of interleukin
(IL)-4 and IL-13 cytokines and their downstream genes including interleukin-13 receptor subunit
alpha-2 (IL13Ra2), interleukin-4 receptor subunit alpha-1 (IL4Ra1), dual oxidase 1 (DUOX1) and
dual oxidase 2 (DUOX2). The protective effects of Selenium-L-methionine on radiation-induced
histopathological damages and changes in the level of these cytokines and genes were detected.

Methods:

Four groups of 20 rats (5 rats in each) namely, control; Selenium-L-methionine, radiation
and radiation plus Selenium-L-methionine were used in this study. 4 mg/kg of Selenium-Lmethionine
was administered 1 day before irradiation and five consecutive days after irradiation.
Irradiation was done using a dose of 15 Gy 60Co gamma rays at 109 cGy/min. All rats were sacrificed
10 weeks after irradiation for detecting changes in IL-4 and IL-13 cytokines, the expressions
of IL13Ra2, IL4Ra1, Duox1 and Duox2 and histopathological changes.

Results:

The level of IL-4 but not IL-13 increased after irradiation. This was associated with increased
expression of IL4Ra1, Duox1 and Duox2, in addition to changes in morphological properties.
Selenium-L-methionine could attenuate all injury markers following lung irradiation.

Conclusion:

Selenium-L-methionine can protect lung tissues against toxic effects of ionizing radiation.
It is possible that the modulation of immune responses and redox interactions are involved in
the radioprotective effect of this agent.

Authors: Lin Feng , Prince Martin R. , Spincemaille Pascal , Wang Yi
Published: December 2018

Background: Quantitative susceptibility mapping (QSM) depicts biodistributions of tissue magnetic susceptibility sources, including endogenous iron and calcifications, as well as exogenous paramagnetic contrast agents and probes. When comparing QSM with simple susceptibility weighted MRI, QSM eliminates blooming artifacts and shows reproducible tissue susceptibility maps independent of field strength and scanner manufacturer over a broad range of image acquisition parameters. For patient care, QSM promises to inform diagnosis, guide surgery, gauge medication, and monitor drug delivery. The Bayesian framework using MRI phase data and structural prior knowledge has made QSM sufficiently robust and accurate for routine clinical practice.

Objective:

To address the lack of a summary of US patents that is valuable for QSM product development and dissemination into the MRI community.

Method:

We searched the USPTO Full-Text and Image Database for patents relevant to QSM technology innovation. We analyzed the claims of each patent to characterize the main invented method and we investigated data on clinical utility.  Results: We identified 17 QSM patents; 13 were implemented clinically, covering various aspects of QSM technology, including the Bayesian framework, background field removal, numerical optimization solver, zero filling, and zero-TE phase.

Conclusion:

Our patent search identified patents that enable QSM technology for imaging the brain and other tissues. QSM can be applied to study a wide range of diseases including neurological diseases, liver iron disorders, tissue ischemia, and osteoporosis. MRI manufacturers can develop QSM products for more seamless integration into existing MRI scanners to improve medical care.
Praxis en el pasado: Aproximaciones a la intervención en el patrimonio arquitectónico de Lima
Authors: Bonilla Polanco Pamela
Published: December 2018

Un monumento integrante del patrimonio cultural es una construcción de gran valor histórico, artístico o científico que pertenece a un determinado grupo humano. Por tanto, es un deber garantizar su salvaguarda para el conocimiento de las generaciones futuras. En el caso particular de Lima, una gran cantidad de edificios históricos se encuentran en estado de deterioro; si no se actúa en el presente, estas corren el riesgo de desaparecer. Por lo tanto, el quehacer patrimonial se considera un tema pendiente de estudio, desarrollo y ejecución desde distintos campos profesionales. Por ello, la presente investigación analizará el aspecto arquitectónico-urbanista de esta situación, indagando modelos de intervención en el patrimonio edificado desde un enfoque conceptual, principista, metodológico y propositivo. Desde el punto de vista de cada arquitecto restaurador, se exponen intervenciones reconocibles en el espacio urbano, con distintos grados de intromisión, que han sido realizadas en los últimos años. Se desarrollan los siguientes casos: la Casona de San Marcos, cuyos patios fueron partícipes de episodios históricos distintos; el antiguo Mercado Municipal de Barranco, en tanto hito urbano representativo de la memoria barranquina; y el centro cultural Ccori Wasi, elemento integrador del conjunto urbano de la Av. Arequipa.

Authors: Stinia Maria
Published: December 2018

Religia jako jeden z przedmiotów szkolnych pełniła w galicyjskich gimnazjach ważną funkcję edukacyjną, a jej istotną częścią składową była liturgika i biblistyka. W procesie nauczania najważniejszym środkiem dydaktycznym był podręcznik szkolny. W ciągu kilkudziesięcioletniego okresu autonomii Galicji posługiwano się między innymi pracami Ludwika Lewartowskiego, Antoniego Tyca, Stanisława Puszeta, Władysława Jougana, Tomasza Dąbrowskiego i Szczepana Szydelskiego. W stopniowo unowocześnianych książkach autorzy starali się uwzględniać wskazania dydaktyki oraz najnowsze odkrycia archeologiczne. Ponadto prowadzono też liczne dyskusje w prasie i podczas zjazdów katechetów mające na celu modernizację procesu nauczania i zwiększenie wychowawczego oddziaływania na uczniów.
Dose-Response Effect of a Digital Health Intervention During Cardiac Rehabilitation: Subanalysis of Randomized Controlled Trial (Preprint)
Authors: Widmer R Jay , Senecal Conor , Allison Thomas G , Lopez-Jimenez Francisco , Lerman Lilach O , Lerman Amir
Published: December 2018

BACKGROUND

Previous data have validated the benefit of digital health interventions (DHIs) on weight loss in patients following acute coronary syndrome entering cardiac rehabilitation (CR).

OBJECTIVE

The primary purpose of this study was to test the hypothesis that increased DHI use, as measured by individual log-ins, is associated with improved weight loss. Secondary analyses evaluated the association between log-ins and activity within the platform and exercise, dietary, and medication adherence.

METHODS

We obtained DHI data including active days, total log-ins, tasks completed, educational modules reviewed, medication adherence, and nonmonetary incentive points earned in patients undergoing standard CR following acute coronary syndrome. Linear regression followed by multivariable models were used to evaluate associations between DHI log-ins and weight loss or dietary adherence.

RESULTS

Participants (n=61) were 79% male (48/61) with mean age of 61.0 (SD 9.7) years. We found a significant positive association of total log-ins during CR with weight loss (r2=.10, P=.03). Educational modules viewed (r2=.11, P=.009) and tasks completed (r2=.10, P=.01) were positively significantly associated with weight loss, yet total log-ins were not significantly associated with differences in dietary adherence (r2=.05, P=.12) or improvements in minutes of exercise per week (r2=.03, P=.36).

CONCLUSIONS

These data extend our previous findings and demonstrate increased DHI log-ins portend improved weight loss in patients undergoing CR after acute coronary syndrome. DHI adherence can potentially be monitored and used as a tool to selectively encourage patients to adhere to secondary prevention lifestyle modifications.

Authors: Braunstein Sarah L , Coeytaux Karen , Sabharwal Charulata J , Xia Qiang , Robbins Rebekkah S , Obeng Beverly , Daskalakis Demetre C
Published: December 2018

BACKGROUND

HIV surveillance data can be used to improve patient outcomes.

OBJECTIVE

This study aimed to describe and present findings from the HIV care continuum dashboards (CCDs) initiative, which uses surveillance data to quantify and track outcomes for HIV patients at major clinical institutions in New York City.

METHODS

HIV surveillance data collected since 2011 were used to provide high-volume New York City clinical facilities with their performance on two key outcomes: linkage to care (LTC), among patients newly diagnosed with HIV and viral load suppression (VLS), among patients in HIV care.

RESULTS

The initiative included 21 facilities covering 33.78% (1135/3360) of new HIV diagnoses and 46.34% (28,405/61,298) of patients in HIV care in New York City in 2011 and was extended to a total of 47 sites covering 44.23% (1008/2279) of new diagnoses and 69.59% (43,897/63,083) of New York City patients in care in 2016. Since feedback of outcomes to providers began, aggregate LTC has improved by 1 percentage point and VLS by 16 percentage points.

CONCLUSIONS

Disseminating information on key facility–level HIV outcomes promotes collaboration between public health and the clinical community to end the HIV epidemic. Similar initiatives can be adopted by other jurisdictions with mature surveillance systems and supportive laws and policies.

BACKGROUND

Autism affects 1 in every 59 children in the United States, according to estimates from the Centers for Disease Control and Prevention’s Autism and Developmental Disabilities Monitoring Network in 2018. Although similar rates of autism are reported in rural and urban areas, rural families report greater difficulty in accessing resources. An overwhelming number of families experience long waitlists for diagnostic and therapeutic services.

OBJECTIVE

The objective of this study was to accurately identify gaps in access to autism care using GapMap, a mobile platform that connects families with local resources while continuously collecting up-to-date autism resource epidemiological information.

METHODS

After being extracted from various databases, resources were deduplicated, validated, and allocated into 7 categories based on the keywords identified on the resource website. The average distance between the individuals from a simulated autism population and the nearest autism resource in our database was calculated for each US county. Resource load, an approximation of demand over supply for diagnostic resources, was calculated for each US county.

RESULTS

There are approximately 28,000 US resources validated on the GapMap database, each allocated into 1 or more of the 7 categories. States with the greatest distances to autism resources included Alaska, Nevada, Wyoming, Montana, and Arizona. Of the 7 resource categories, diagnostic resources were the most underrepresented, comprising only 8.83% (2472/28,003) of all resources. Alarmingly, 83.86% (2635/3142) of all US counties lacked any diagnostic resources. States with the highest diagnostic resource load included West Virginia, Kentucky, Maine, Mississippi, and New Mexico.

CONCLUSIONS

Results from this study demonstrate the sparsity and uneven distribution of diagnostic resources in the United States, which may contribute to the lengthy waitlists and travel distances—barriers to be overcome to be able to receive diagnosis in specific regions. More data are needed on autism diagnosis demand to better quantify resource needs across the United States.

BACKGROUND

The internet is being widely used for seeking health information. However, there is no consensus on the association between health information seeking on the internet and the use of health care services.

OBJECTIVE

We examined the association between health information seeking via the internet and physician visits. In addition, we investigated the association between online health information seeking and the decisions to visit and not to visit a physician.

METHODS

We used the cross-sectional electronic health (eHealth) data of 18,197 participants from the seventh survey of the Tromsø Study (Tromsø 7). The participants were aged ≥40 years and living in Tromsø, Norway. We used logistic regression models to examine the association between online health information seeking and physician visits, the decision to visit a physician, and the decision not to visit a physician, with adjustment for the demographic status, socioeconomic status, and health status of the participants.

RESULTS

The use of Web search engines was associated with a physician visit. However, the association was moderated by age, and the OR decreased as age increased. The ORs for the use of Web search engines were 1.99 (95% CI 1.94-2.02) and 1.07 (95% CI 1.03-1.12) at ages 40 and 80 years, respectively. The decision to visit a physician was associated with the use of Web search engines (OR 2.95, 95% CI 2.03-4.46), video search engines (OR 1.43, 95% CI 1.21-1.70), and health apps (OR 1.26, 95% CI 1.13-1.42). The association between social media use and the decision to visit a physician was moderated by gender. Women who used social media had 1.42 (95% CI 1.31-1.55) times higher odds of deciding to visit a physician, whereas the decision to visit a physician was not different between men who used social media and those who did not use social media. Conversely, the decision not to visit a physician was associated with the use of Web search engines (OR 2.78, 95% CI 1.92-4.18), video search engines (OR 1.27, 95% CI 1.07-1.51), social media (OR 1.28, 95% CI 1.10-1.49), and health apps (OR 1.20, 95% CI 1.07-1.35).

CONCLUSIONS

Health information found on the internet was positively associated with both the decision to visit a physician and the decision not to visit a physician. However, the association of health information seeking with the decision to visit a physician was slightly stronger than the association with the decision not to visit a physician. This could imply that the use of eHealth services is associated with a resultant increase in physician visits. In summary, our findings suggest that the internet serves as a supplement to health care services rather than as a replacement.

Published: December 2018

BACKGROUND

Medical care for the Chinese population has been focused on first-line treatment, but with little follow-up on treated patients. As an important part of clinical work, follow-up evaluations are of great significance for the long-term survival of patients and for clinical and scientific research. However, the overall follow-up rate of discharged patients after surgery has been low for many years because of the limitations of certain follow-up methods and the presence of objective, practical problems.

OBJECTIVE

This study aimed to construct a new two-way interactive telemedicine follow-up platform to improve the collection of clinical data after cardiac surgery and provide reliable and high-quality follow-up services.

METHODS

Computer and network technologies were employed in the context of “Internet +” to develop follow-up databases and software compatible with a mobile network. Postoperative follow-up quality data including the follow-up rate and important postoperative indices were used as standards to evaluate the new follow-up management model after cardiac surgery.

RESULTS

This system has been officially operated for more than 5 years. A total of 5347 patients undergoing cardiac surgery have been enrolled, and the total follow-up rate was 90.22%. In addition, 6349 echocardiographic images, 4717 electrocardiographic images, and 3504 chest radiographic images have been uploaded during follow-up assessments. The international standardized ratio was 20,696 person-times.

CONCLUSIONS

This new management follow-up platform can be used to effectively collect clinical data, provide technical support for academic research, extend medical services, and provide more help to patients. It is of great significance for managing patients after cardiac surgery.
Patients’ Perceptions of Portal Use Across Care Settings: Qualitative Study (Preprint)

Published: December 2018

BACKGROUND

Patient portals are a promising instrument to improve patient-centered care, as they provide patients information and tools that can help them better manage their health. The implementation of portals in both the inpatient and outpatient setting gives health care providers an opportunity to support patients both during hospitalization and after discharge. Thus, there is a need to better understand how inpatient and outpatient portals are used across care contexts.

OBJECTIVE

This study aimed to examine patients’ perceptions of using inpatient and outpatient portals across the care settings, including how they used the portals and the benefits and concerns associated with portal use.

METHODS

This study was conducted in a large Midwestern academic medical center consisting of seven hospitals. We interviewed 120 patients who had used an inpatient portal during their hospitalization, at 15 days and 6 months postdischarge, to determine their perspectives of portal use in both hospital and outpatient settings. Interview transcripts were analyzed inductively and deductively by using team coding processes consistent with a grounded theory approach.

RESULTS

Interviews focused on three main areas of portal use: experience with the portal features, perceived benefits, and concerns. Responses at 15 days (n=60) and 6 months (n=60) postdischarge were consistent with respect to perceptions about portal use. Patients identified viewing their health information, managing their schedule, and communicating with providers as notable activities. Convenience, access to information, and better engagement in care were indicated as benefits. Concerns were related to technology issues and privacy/security risks.

CONCLUSIONS

Implementation of inpatient portals as a complement to outpatient portals is increasing and can enable patients to better manage aspects of their care. Although care processes vary substantively across settings, the benefits of convenience, improved access to information, and better engagement in care provide opportunities for portal use across care settings to support patient-centered care.
