Validation and Acceptability of a Cuffless Wrist-Worn Wearable Blood Pressure Monitoring Device Among Users and Health Care Professionals: Mixed Methods Study

Background Blood pressure (BP) is an important modifiable cardiovascular risk factor, yet its long-term monitoring remains problematic. Wearable cuffless devices enable the capture of multiple BP measures during everyday activities and could improve BP monitoring, but little is known about their validity or acceptability. Objective This study aimed to validate a wrist-worn cuffless wearable BP device (Model T2; TMART Technologies Limited) and assess its acceptability among users and health care professionals. Methods A mixed methods study was conducted to examine the validity and comparability of a wearable cuffless BP device against ambulatory and home devices. BP was measured simultaneously over 24 hours using wearable and ambulatory devices and over 7 days using wearable and home devices. Pearson correlation coefficients compared the degree of association between the measures, and limits of agreement (LOA; Bland-Altman plots) were generated to assess measurement bias. Semistructured interviews were conducted with users and 10 health care professionals to assess acceptability, facilitators, and barriers to using the wearable device. Interviews were audio recorded, transcribed, and analyzed. Results A total of 9090 BP measurements were collected from 20 healthy volunteers (mean 20.3 years, SD 5.4; N=10 females). Mean (SD) systolic BP (SBP)/diastolic BP (DBP) measured using the ambulatory (24 hours), home (7 days), and wearable (7 days) devices were 126 (SD 10)/75 (SD 6) mm Hg, 112 (SD 10)/71 (SD 9) mm Hg and 125 (SD 4)/77 (SD 3) mm Hg, respectively. Mean (LOA) biases and precision between the wearable and ambulatory devices over 24 hours were 0.5 (−10.1 to 11.1) mm Hg for SBP and 2.24 (−17.6 to 13.1) mm Hg for DBP. The mean biases (LOA) and precision between the wearable and home device over 7 days were −12.7 (−28.7 to 3.4) mm Hg for SBP and −5.6 (−20.5 to 9.2) mm Hg for DBP. The wearable BP device was well accepted by participants who found the device easy to wear and use. Both participants and health care providers agreed that the wearable cuffless devices were easy to use and that they could be used to improve BP monitoring. Conclusions Wearable BP measures compared well against a gold-standard ambulatory device, indicating potential for this user-friendly method to augment BP management, particularly by enabling long-term monitoring that could improve treatment titration and increase understanding of users’ BP response during daily activity and stressors.
Research on Semantic Orientation Analysis for Topics in Chinese Sentences

This paper presents how to identify the topics as well as the relations bewteen the topics and the sentimental descriptive terms in a Chinese sentence,and how to compute the sentiment orientation(polarity) of the topics.We extract the topics and their attributes from a sentence with the help of a domain ontology,then identify the relations between the topics and sentimental descriptive terms based on parsing results,and finally determine the polarity of each topic in the sentence.The experiment has shown that the F-measure of the improved SBV polarity transfer algorithm for identifying topics and the polarity reaches 72.41% as compared with the manual annotation corpus which serves as a golden standard.It is increased by 7.6% and 2.09% than the F-measure of the original SBV and VOB polarity transfer algorithm respectively.Therefore,the proposed improved SBV polarity transfer algorithm is reasonable and effective.
Cloud Computing Architectural Patterns

Cloud computing has been one of the most disruptive technologies, which has changed the way IT is consumed by enterprises, both small and large. The ability to subscribe to “as-a-service” consumption model, while converting capital expenditure to operational expenditure, has been a key driver for Cloud adoption. Rapid provisioning and deprovisioning of services, elastic scaling of infrastructure resources and self-service ability for users are some of the key characteristics and benefits offered by Cloud. Infrastructure as a Service (IaaS) provides the basic building block, with Platform as a Service (PaaS) providing a layer of abstraction on top of IaaS and similarly Software as a Service (SaaS) providing a layer of abstraction on top of PaaS. Moving up the layers reduces complexity and enables users to tap into a much larger spectrum of benefits that Cloud computing has to offer. While Cloud opens the door for “as-a-service” consumption model, there are many additional benefits that can be realized by enterprises beyond the typical IaaS, PaaS and SaaS. A number of these benefits can be realized by leveraging Cloud in different scenarios and use cases. For example, an enterprise may continue to pursue a traditional non-Cloud based infrastructure deployment strategy, however, it could use a public Cloud for storage elasticity. Such use cases exemplify many atypical benefits that Cloud can provide, which often got overlooked. This paper will present a number of such cloud deployment use cases that go beyond the typical IaaS usage of cloud. A hierarchical architectural model of cloud solution pattern is proposed to describe both the business requirements and technical considerations of these use cases. These cloud architectural patterns are further elaborated through real-life case studies and examples. Cloud Computing Architectural Patterns
Development of a wearable exoskeleton rehabilitation system based on hybrid control mode

Lower limb rehabilitation exoskeletons usually help patients walk based on fixed gait trajectories. However, it is not suitable for unilateral lower limb disorders. In this article, a hybrid training mode is proposed to be applied in rehabilitation for unilateral lower limb movement disorders. The hybrid training includes two modes, that is, the passive training mode and the active assist mode. At an early stage of the rehabilitation therapy, the passive training mode is utilized, in which microelectromechanical systems-based attitude and heading reference system is used to collect the gait trajectory of the healthy limb. The exoskeleton on the unhealthy limb will be driven to track the joint trajectory of the healthy limb. If the patient’s abilities recovered, the rehabilitation system can be switched to the active assist mode. Two force sensors are imbedded into the interface on the thigh to measure the interaction information in order to detect the patient’s initiative walking intention. In the active mode, the walking gait trajectory is modified and generated based on the gait trajectory of the healthy side via the attitude and heading reference system. In this article, a position close control loop is designed to drive the mechanical leg to help the unhealthy limb walk. Laboratory experiments are performed on a healthy human subject to illustrate the proposed approach. Experimental results show that the proposed method can be applied and extended in the passive and active rehabilitation mode for the unilateral lower limb disorders.
SYMPOSIUM ON APPLIED REGRESSION Statistical Methods for Comparing Regression Coefficients between Models1

Statistical methods are developed for comparing regression coefficients between models in the setting where one of the models is nested in the other. Comparisons of this kind are of interest whenever two explanations of a given phenomenon are specified as linear models. In this case, researchers should ask whether the coefficients associated with a given set of predictors change in a significant way when other predictors or covariates are added as controls. Simple calculations based on quantities provided by routines for regression analysis can be used to obtain the standard errors and other statistics that are required. Results are also given for the class of generalized linear models (e.g., logistic regression, log-linear models, etc.). We recommend fundamental change in strategies for model comparisons in social research as well as modifications in the presentation of results from regression or regression-type models.

RESUME Introduction: Sleep disorders have adverse effects on the body, especially the cardio-metabolic effects. The prevalence is steadily increasing due to technological advances, industrialization, and unhealthy lifestyles. The aim of this study was to report on the prevalence of sleep disorders and the associated cardiovascular risk factors in the school setting. Methods. We carried out a cross-sectional study in three randomly selected urban (one) and rural (two) schools. The study population was composed of all second cycle pupils who consented to participate in the study. Results. A total of 815 pupils (420 rural and 395 urban) participated in this study. Their average age was 18±3 years, and 54% were females. The rural participants were older (p 5) was 40.3% in the urban, and 41% in the rural participants (p=0.785). Among rural pupils, poor sleep quality was three times more frequent in those who smoked tobacco (p=0.028), and two times more frequent in those who were inactive (p=0.018). In urban participants, High Blood pressure (p=0.004) and tobacco use (p= 0.045) were associated with poor sleep quality. Conclusion. The prevalence of poor sleep quality is high in the school setting in Cameroon. This is associated with high blood pressure, tobacco use, physical inactivity, and overweight/obesity.

How an elegant 3D curriculum modelling approach offers a way through the complexity of the CSU Degree Initiative

An ‘enfolded’ student learning experience In my Summit presentation I invited the audience to ‘entertain the radical thought that the more elegant a curriculum design, the more integrated or holistic the student’s course-long, coursewide experience can be’ (McKenzie, Higgs, & Simpson, 2011). This points us towards the first sense in which an elegant curriculum modelling approach offers CSU a way through the complexity of the CSU Degree Initiative: it provides course teams and students with a common language with which to describe the goal and processes of a ‘fit-for-greater-purpose’ education for practice. The ‘curriculum of becoming mindspace’ is a family of ideas that offers a metamodel for university curriculum design: it is a generic or content free model that can provide a template for any professional preparation program. The goal of a university curriculum of becoming is to graduate ‘novice rounded, grounded practitioners’. To this end, a university curriculum of becoming cultivates individual development in four dimensions:
Dynamic Host Configuration Protocol (DHCPv6) Options for Shared IP Addresses Solutions

This memo defines Dynamic Host Configuration Protocol version 6 (DHCPv6) Options to be used in the context of shared IP address solutions. In some deployment scenarios, DHCP (IPv4) cannot be used to configure customer devices because only IPv6 capabilities are deployed (e.g., DS-lite context or IPv6 Port Range). Therefore, DHCPv6 may be used to convey IPv4-related configuration information such as Port Range and/or Port Extended IPv4 addresses. This document defines also a DHCPv6 Option aiming to convey the IPv6 prefix to be used to build IPv4 Embedded IPv6 addresses [I-D.ietf-behave-address-format].
The Natural History of Cervical Spondylotic Myelopathy and Ossification of the Posterior Longitudinal Ligament: A Review Article

Cervical spondylotic myelopathy (CSM) is the chronic and slow deterioration of cervical spinal cord function. The pathophysiology of this condition is multifactorial, including compression, repetitive trauma, and vascular compromise of the spinal cord. Clinically, it presents as a progressive decline in patients’ appendicular neurological function. The natural history of this disease varies but, it is well-known that the duration and degree of compression correlate negatively with prognosis. A mild degree of CSM tends to stabilize with potential improvement over time while more severe CSM tends to progress. Surgical intervention has shown to positively alter the natural history of the disease by halting the progression with some restoration of function. Ossification of the posterior longitudinal ligament (OPLL) is a chronic disease that results in progressive ossification of the posterior longitudinal ligament of the spine. It commonly affects the cervical spine. The etiology is multifactorial in nature, including genetic and environmental factors. The progressive nature of this condition and the resultant cervical spinal stenosis make it one of the main causes of cervical myelopathy (CM). There is no medical therapy for this disease, and surgery is reserved for patients with CM caused by spinal cord compression. In this article, we review the different aspects of the natural history of both CSM and OPLL.
Concepts, Issues, and Standards. Applications Using the Unified Medical Language System: A Preliminary Evaluation of the UMLS Metathesaurus for Patient Record Classification

The UMLS project seeks to provide a unified interface to biomedical knowledge resources. Patient medical records are an enormous repository of clinical intervention and outcome, and are drawing increasing attention in the pursuit of quality assurance, outcomes research, and epidemiologic analysis. We sought to evaluate an unedited version of the preliminary UMLS Metathesaurus, Meta-1, for the automated coding of medical diagnosis and surgical procedures. Identical evaluations were undertaken using SNOMED and the Mayo Clinic indexing lexicon. Meta-1 performed comparably to the comparison clinical indexing systems, although all systems exhibited problems associated with clinical attribute levels and modifier combinations.
An Adaptive Controller Of Glycemia Based On A Physiological Model Of The Insulin-dependent Glucose Removal

This paper presents an adaptive controller based on a minimal nonlinear model of the insulin/ glucose regulatory system. The past fractional removal rates of plasma glucose are first evaluated. from the net balance between glucose infusion and plasma level. The insulin-dependent fractional removal can also be expressed, in a discretized form, as a weighted sum of its past values and of the insulin signal. Evaluations of the removal rates are used to recursively adjust the parameters of the sum which can then be used to predict the fate of plasma glucose and to adjust the infusions to maintain the desired glycemia. In vivo experiments in pigs show that the controller promptly reacts to fast and large variations of the glucose removal induced by iv or sc injections and staircase infusions of insulin. Average glycemia was maintained at 99.9+8.7% of the set point (+ coefficient of variation). The predictive capability of the controller allows an irregular glucose monitoring during the experiment at intervals varying from 2 to 7 min.
A computational study to assess the effect of the coronary hemodynamics on the mechanical stresses of stenotic atherosclerotic plaques

Atherosclerotic plaque rupture is the common pathological condition of the acute ischemic syndromes of sudden cardiac death and acute myocardial infarction. The rupture of the fibrous cap of a coronary plaque may result in a thrombus formation that would prevent the perfusion of blood downstream of the myocardium. A probable cause of plaque rupture is the mechanical stress induced by the artery wall stretching from the physiological flow of blood and the intraluminal pressure within the coronary arteries. We used computational fluid-structure interaction methods to analyze the effects of coronary blood flow on stenotic atherosclerotic plaques to determine the mechanical stresses within the plaque’s components. We analyzed the effect of the fibrous cap thickness, necrotic core stiffness, and percentage of area stenosis on the mechanical stresses within using comparable models of stenosed arteries. We then analyzed the effect of transient hemodynamic flow using realistic patient-specific geometries under normal coronary flow and pressure. The transient results were used to calculate the amplitude and mean stress for fatigue analyses. Based on this approach, we developed several hypotheses: mechanical fatigue in the fibrous cap is the ultimate characteristic that triggers the rupture; fibrous cap mechanical fatigue (FCMF) can be the result of the combined effects of the cap thickness, relative inclusion stiffness and percentage of stenosis; FCMF can be influenced by the global structure of the obstructive pathology in particular in the context of multiple stenoses, we also show that the anisotropic properties of the collagen fibers within the cap can influence the rupture mechanism. Our results indicate that the combination of a thin fibrous cap, a soft lipid core and a large percentage of stenosis contribute to high mechanical stress magnitudes. Such stresses in mild stenoses can have similar critical behaviors to those normally associated with higher percentage%%%%La rupture de plaques atherosclerotiques est la condition pathologique la plus frequente impliquee dans le syndrome ischemique aigu pouvant mener a l’infarctus du myocarde et a la mort du a l’arret cardiaque. La rupture du cap fibreux de la plaque coronarienne peut resulter dans la formation d’un thrombus qui peut eventuellement empecher la perfusion sanguine en aval du lit myocardique. Une cause possible de la rupture de la plaque est l’etablissement de contraintes mecanique induites par la deformation de la paroi arterielle sous l’ecoulement sanguin et la pression intraluminale a l’interieur des arteres coronaires. Nous avons utilise des methodes de simulation par interaction fluide-structure pour analyser les effets de l’ecoulement coronarien sur les plaques atherosclerotiques pour determiner les contraintes mecaniques sur les constituants de la plaque. Nous avons analyse l’effet de l’epaisseur du cap fibreux, la rigidite de l’inclusion necrotique et le pourcentage en surface de la stenose sur les contraintes mecaniques en utilisant des modeles…
Clinical Evaluation of Balance in Adults with Traumatic Brachial Plexus Injury

Objectives: The study aimed to find if the balance was impaired in patients of traumatic brachial plexus injury. The objectives were to assess the static balance using single leg stance test time and dynamic balance using the time component of modified dynamic gait index in adults with partial or complete brachial plexus injury (study group) and compare it with healthy normal adults (control group). Methodology: It was a cross-sectional, comparative, observational, single-center study carried out for a period of 6 months including statistical analysis. Total 20 patients with partial or complete traumatic brachial plexus injury and 20 age and gender-matched healthy normal adults were recruited from 18-45 years of age, of either gender who were willing to participate in the study. Individuals with any congenital, cognitive, vascular, neurological issues or with injuries to lower limb were excluded. Static balance was measured using single leg stance test time (in seconds) thrice for each leg (its average was then taken) and the dynamic balance was measured using the score out of 24 for time variable of modified dynamic gait index. Results: No statistical difference in left (p=0.3141) or right (p=0.1572) single leg stance test time was observed, however, there was a statistical difference in ‘time’ component of modified dynamic gait index between the 2 groups (p<0.001). Conclusion: The study shows that the static balance was not affected but the dynamic balance was affected in patients with traumatic brachial plexus injury.
