We developed a smart phone application to measure participants' food-reward perceptions and eating behavior in their naturalistic environment. Intensity ratings (0 - not at all to 10 - very strongly) of perceived anticipation of food (wanting) and food enjoyment at endpoint of intake (liking) were recorded as they occurred over a period of 14 days. Moreover, food craving trait, implicit and explicit attitude towards healthy food, and body composition were assessed. 53 participants provided complete data. Participants were classified by percentage of body fat; 33 participants with lower body fat (L-group) and 20 with higher body fat (H-group; ≥25% body fat for males and ≥32% for females)...

The scoliometer is an inclinometer commonly used in scoliosis screening. The device is used during an Adam's forward bend test, in which a patient bends forward at the hips to measure deformity of the rib cage and spinal column. If a sufficient angle of rotation is measured, then the appropriate referrals and x-rays can be made and taken. This ubiquitous screening tool allows for a quick and simple scoliosis screening and is a mainstay of scoliosis management. With the advent and rapid improvement of smart phone technology, many scoliometer applications have become readily accessible...

Research reports show increased prevalence of habitual khat chewing among various parts of the community in Ethiopia. Some users experience problems controlling their use; withdrawal symptoms may be adding to difficulties with reducing or ceasing use. We aimed to describe the nature and the time course of any withdrawal syndrome in relation to the cessation of khat use over the first 2 weeks of a quit attempt. Fifty-nine participants between the ages of 18 and 35 and who have already chewed ≥1 bundle of khat in their life with a chewing frequency of ≥3 days per week were recruited from Adama Science and Technology University campus...

BACKGROUND: The use of mobile technology such as phone applications (apps) has been proposed as an efficient means of providing health and clinical information in a variety of healthcare settings. We developed the Health-e Babies app as an Android smart phone application for pregnant women attending a tertiary hospital in a low socio-economic community, with the objective of providing health information about early pregnancy that would increase maternal confidence and reduce anxiety. Based on our earlier research, this form of health communication was viewed as a preferred source of information for women of reproductive age...

PURPOSE: Hypertension (HTN) is significantly under-treated in stroke survivors. We examined usability and efficacy of a mHealth -based care model for improving post-stroke HTN control (Funding: AHRQ R21HS021794). METHODS: We used a RCT design. Planned study duration was 90 days. Intervention arm (IA) participants measured their BP daily using a smart phone and wireless BP monitor. This was transmitted automatically to the study database. Investigators (Physician + PharmD) made bi-weekly medication adjustments to achieve the BP goal...

Liquid crystals (LCs) are anisotropic fluids that combine the long-range order of crystals with the mobility of liquids1,2 . This combination of properties has been widely used to create reconfigurable materials that optically report information about their environment, such as changes in electric fields (smart-phone displays) 3 , temperature (thermometers) 4 or mechanical shear 5 , and the arrival of chemical and biological stimuli (sensors)6,7 . An unmet need exists, however, for responsive materials that not only report their environment but also transform it through self-regulated chemical interactions...

As people age, physiological changes can occur causing deterioration of one or more of the senses, including hearing, vision, taste, and smell. The loss of sensory function can decrease the extent to which older adults can communicate, especially with their healthcare providers. The purpose of this article is to examine communication between older adults and healthcare providers, focusing on best practices and devices that can enhance and benefit their health and well-being. One consideration is the use of digital technology, such as smart phones, electronic tablets, and computers, to help mitigate the effects of aging on communication...

Inflammatory bowel disease (IBD), comprised of Crohn's disease and ulcerative colitis, affects 1.6 million people in the United States. Although effective medical treatments exist to treat the disease, outcomes are still suboptimal. The reasons for poor outcomes vary but include nonadherence to therapy, inadequate monitoring of patients, limited access to IBD specialty care, concurrent psychiatric disease, limited patient knowledge of the disease and treatments, and patient provider discordance. Telemedicine is a candidate intervention that can be used to improve patient outcomes through more frequent monitoring, patient self-management, delivery of education (patient and provider), and to increase access to multidisciplinary IBD care...

Background: There has been a notable disconnect between theories of behavior change and behavior change interventions. Because few interventions are both explicitly and adequately theory-based, investigators cannot assess the impact of theory on intervention effectiveness. Theory-based interventions, designed to deliberately engage the theory's proposed mechanisms of change, are needed to adequately test theories. Thus, systematic approaches to theory-based intervention development are needed...

We introduce an approach to predict deterioration of reaction state for people having neurological movement disorders such as hand tremors and nonvoluntary movements. These involuntary motor features are closely related to the symptoms occurring in patients suffering from Huntington's disease (HD). We propose a hybrid (neurofuzzy) model that combines an artificial neural network (ANN) to predict the functional capacity level (FCL) of a person and a fuzzy logic system (FLS) to determine a stage of reaction. We analyzed our own dataset of 3032 records collected from 20 test subjects (both healthy and HD patients) using smart phones or tablets by asking a patient to locate circular objects on the device's screen...

Fall detection is a very important challenge that affects both elderly people and the carers. Improvements in fall detection would reduce the aid response time. This research focuses on a method for fall detection with a sensor placed on the wrist. Falls are detected using a published threshold-based solution, although a study on threshold tuning has been carried out. The feature extraction is extended in order to balance the dataset for the minority class. Alternative models have been analyzed to reduce the computational constraints so the solution can be embedded in smart-phones or smart wristbands...

Background: Low physical activity level is associated with poor prognosis in patients with colorectal cancer (CRC). To increase physical activity, technology-based platforms are emerging and provide intriguing opportunities to prescribe and monitor active lifestyle interventions. The "Interval Walking in Colorectal Cancer"(I-WALK-CRC) study explores the feasibility and efficacy a home-based interval-walking intervention delivered by a smart-phone application in order to improve cardio-metabolic health profile among CRC survivors...

Peripheral Arterial Disease (PAD) is a chronic cardiovascular disease. It is highly prevalent in older adults. Mobile Health (mHealth) and Telehealth technologies are considered two central digital solutions for enabling patient-centred care. There is evidence that physical activity apps can improve health outcomes in adults. The aim of this project is to develop a prototype of smart phone app to target patients with PAD, which we named YORwalK, to promote exercise and track changes in walking ability in this population...

BACKGROUND: 360° virtual reality (VR) video is an exciting and evolving field. Current technology promotes a totally immersive, 3-dimensional (3D), 360° experience anywhere in the world using simply a smart phone and virtual reality headset. The potential for its application in the field of surgical education is enormous. The aim of this study was to determine knot tying skills taught with a 360-degree VR video compared to conventional 2D video teaching. MATERIAL AND METHODS: This trial was a prospective, randomised controlled study...

It has long been proposed that diurnal rhythms are disturbed in bipolar disorder (BD). Such changes are obvious in episodes of mania or depression. However, detailed study of patients between episodes has been rare and comparison with other psychiatric disorders rarer still. Our hypothesis was that evidence for desynchronization of diurnal rhythms would be evident in BD and that we could test the specificity of any effect by studying borderline personality disorder (BPD). Individuals with BD (n = 36), BPD (n = 22) and healthy volunteers (HC, n = 25) wore a portable heart rate and actigraphy device and used a smart-phone to record self-assessed mood scores 10 times per day for 1 week...

Historically, resource conflicts have often centered on fuel minerals (particularly oil). Future resource conflicts may, however, focus more on competition for nonfuel minerals that enable emerging technologies. Whether it is rhenium in jet engines, indium in flat panel displays, or gallium in smart phones, obscure elements empower smarter, smaller, and faster technologies, and nations seek stable supplies of these and other nonfuel minerals for their industries. No nation has all of the resources it needs domestically...

Coding for proteins has been considered the main function of RNA since the "central dogma" of biology was proposed. The discovery of noncoding transcripts shed light on additional roles of RNA, ranging from the support of polypeptide synthesis, to the assembly of subnuclear structures, to gene expression modulation. Cellular RNA has therefore been recognized as a central player in often unanticipated biological processes, including genomic stability. This ever-expanding list of functions inspired us to think of RNA as a "smart" phone, which has replaced the older obsolete "cellular" phone...

Wearable biosensors, such as those embedded in smart phones, can provide data to assess neuro-motor control in mobile settings, at homes, schools, workplaces and clinics. However, because most machine learning algorithms currently used to analyze such data require several steps that depend on human heuristics, the analyses become computationally expensive and rather subjective. Further, there is no standardized scale or set of tasks amenable to take advantage of such technology in ways that permit broad dissemination and reproducibility of results...
