They generally integrate the MEMS-designed inertial sensors, including accelerometer, gyroscope and compass, which provide a convenient and inexpensive way to collect motion data of users. Such rich, continuous motion data provide great potential for remote healthcare and decease diagnosis. Information processing algorithms play the critical role in these approaches, which is to extract the motion signatures and to access different kinds of judgements. This paper reviews key algorithms in these areas. In particular, we focus on three kinds of applications: 1) gait analysis; 2) fall detection and 3) sleep monitoring. They are the most popular healthcare applications based on the inertial data. By categorizing and introducing the key algorithms, this paper tries to build a clear map of how the inertial data are processed; how the inertial signatures are defined, extracted, and utilized in different kinds of applications. This will provide a valuable guidance for users to understand the methodologies and to select proper algorithm for specifi c application purpose.展开更多

Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventricular junctional arrhythmia, was diagnosed. We recommend that preoperative risk evaluation be required for multi-risk patients. Likewise, emergent measures should to be established in advance. This case reminds us that atrial pacing can be an optimal management technique once cardiogenic shock has occurred.展开更多

Methods This study enrolled a consecutive series of 36 patients with solitary supratentorial cavernous malformations and secondary epilepsy who underwent surgery with intraoperative ECoG monitoring in the Department of Neurosurgery between January 2004 and January 2008. The patients were composed of 15 males and 21 females, aged between 8 and 52 years(mean age 27.3±2.8 years) at the time of surgery. Epilepsy history, the type of epilepsy at the presentation, lesion location, the incidence of residual epileptiform discharges, and postoperative outcomes were evaluated. Results Histopathological examination indicated cavernous malformations and hippocampal sclerosis in 36 and 5 cases, respectively. Neuronal degeneration, glial cell proliferation, and neurofibrillary tangles were found in all the resected cerebral tissues of extended lesionectomy of residual epileptic foci. Lesionectomy, anterior temporal lobectomy, anterior temporal lobectomy plus cortical thermocoagulation, extended lesionectomy, extended lesionectomy plus cortical thermocoagulation were performed in 4, 4, 1, 14, and 13 cases, respectively. Residual epileptiform discharges were captured in 9 out of the 14 patients who had additional cortical thermocoagulation. According to Engle class for postoperative outcomes, 27 cases were class I(75.00%), 5 were class II(13.89%), 2 were class III(5.56%), and 2 were class IV(5.56%), thus the total effective rate(class I+class II) was 88.89%. Neither of epilepsy history, the type of epilepsy, and the location of cavernous malformation was significantly related to outcomes(P>0.05). A significant relationship was found between the incidence of residual epileptiform discharges and outcomes(P=0.041). Conclusions Intraoperative ECoG monitoring, the application of different surgical approaches, and the resection of residual epileptic foci could produce good result in the surgical treatment of supratentorial cavernous malformation with secondary epilepsy. Postoperative residual epileptiform discharges could be a useful predictor for evaluating the outcomes.展开更多

This article reviews previous research on the design of various types of decision trees to identify the relevant decision-making parameters that should be incorporated into enhanced usage of decision trees. This article proposes a methodology for screening breast and prostate cancers. While an accounting is made for various financial costs and benefits, comments are made on the limitations of the modeling exercise through identification of problems in assigning probabilities, the use of samples in ascertaining population parameters, ethical concerns, and measuring a cost per life year. This article concludes with prospects for future research including private sector versus public sector financing and the incorporation of opportunity costs into the decision-making process.展开更多

As well as a health informatics role in improving the uptake and efficiency of current health services, mobile communication-assisted health care （m-health） also opens opportunities for services that are strikingly new and curative, in particular delivering personal health behaviour change programmes. Herein, we report the preliminary findings of a health-promotion survey titled ＂Mobile Apps User Trend Analysis of Turkish People＂. The survey examines the information needs and media preferences of women and men who research health information and use mobile apps for their healthcare in everyday life. Also this study tries to recover the behaviour of people and what applications they are downloading with respect to health, wellness, and medical mobile applicaitons. In looking the data, it appears that adoption of mHealth is growing at a furious pace. In this context, improvements to health communication have the potential to make a significant role to a promising new medium for health education and communication.展开更多

The magnetic nanoparticles, which integrate uniquely appealing features of magnetic manipulation, nanoscale heat generator, localized magnetic field and enzyme-mimics, prompt the development and application of magnetic nanoparticles-based cancer medicine. Considerable success has been achieved in improving the magnetic resonance imaging(MRI) sensitivity, and the therapeutic function of the magnetic nanoparticles should be given adequate attention. This work reviews the current status and applications of magnetic nanoparticles based cancer therapy. The advantages of magnetic nanoparticles that may contribute to improved therapeutics efficacy of clinic cancer treatment are highlighted here.展开更多

Among diverse strategies for achieving theranostic capabilities, surface-nanopore engineering based on mesoporous silica coating has attracted great interest because of their negligible cytotoxicity and chemically active surface that can be easily modified to introduce various functional groups(e.g.,-COOH,-NH_2,-SH, etc.) via silanization, which can satisfy various requirements of conjugating biological molecules or functional nanoparticles. In addition,the nanopore-engineered biomaterials possess large surface area and high pore volume, ensuring desirable loading of therapeutic guest molecules. In this review, we comprehensively summarize the synthetic procedure/paradigm of nanopore engineering and further broad theranostic applications. Such nanopore-engineering strategy endows the biocompatible nanocomposites(e.g., Au,Ag, graphene, upconversion nanoparticles, Fe_3O_4, MXene, etc.) with versatile functional moieties, which enables the development of multifunctional nanoplatforms for multimodal diagnostic bio-imaging, photothermal therapy, photodynamic therapy,targeted drug delivery, synergetic therapy and imaging-guided therapies. Therefore, mesoporous silica-based surface-nanopore engineering integrates intriguing unique features for broadening the biomedical applications of the single mono-functional nanosystem, facilitating the development and further clinical translation of theranostic nanomedicine.展开更多

However, poor selectivity, high toxicity and intrinsic or acquired drug resistance profoundly limit their application, which encourages the development of novel transition metal-based anticancer agents with different mechanisms of action. To this end, transition metal complexes that can simultaneously act on more than one target, termed as single-molecule multi-targeting complexes, have attracted increasing attention because of their enhanced efficacy and diminished chance of drug resistance. In this review, we systematically discuss the recent progress in the development of platinum- and ruthenium-based anticancer agents, in particular the rational design of platinum and ruthenium complexes with multi-targeting features.展开更多
