A study of internet searches for medical information in dermatology patients: The patient–physician relationship

BackgroundThe use of the Internet to search for medical information is considered by some physicians as an invasion of their medical domain and a reflection of a lack of trust in their advice and recommendations. ObjectiveThe main objective of this study was to estimate the amount of medical information gathered from the Internet and to establish whether these online searches reflect a lower degree of patient satisfaction. Patients and methodsA survey was conducted among 175 patients seen at the melanoma and psoriasis units of San Cecilio University Hospital in Granada, Spain between May 2010 and December 2011. ResultsOnline searches for medical information were performed by 44.4% of patients who returned correctly completed questionnaires. The main reasons given for these searches were to complement appropriate information provided by the physician (67.3%) and to gather information before consultation with the physician (36.5%). Variables associated with the search for medical information on the Internet in the multivariate analysis were a higher educational level, a higher score on two items in the Need for Cognition Scale, and consultation of mass media other than the Internet. LimitationsStudies with larger numbers of patients and other diseases, however, are required to confirm these results. ConclusionsThe search for medical information is a widespread reality among patients with psoriasis and melanoma and it is not associated with a poor relationship with the physician. Dermatologists can play a beneficial role by recommending trustworthy Internet sites during the patient's visit and by promoting the development of pages by scientific societies to provide high-quality information.

The World Wide Web and clinical practice: do sports and musculoskeletal physiotherapists recommend Internet resources to their patients?

Background: With rapid advancement in technology, a plethora of health information is now available on the Internet. However, the quality and accuracy of this information is highly variable. Consequently, this could pose a potential risk to patients where online information may lead to incorrect self-diagnosis and self-management. It is therefore a responsibility of physiotherapists, who are at a vantage point as primary practitioners, to direct patients towards trustworthy Internet resources. By recommending specific websites to patients, physiotherapists can help to alleviate concerns about patients accessing poor quality information, thus performing the role of ‘e-gatekeepers’ of information. Nonetheless, little is known about whether physiotherapists do so.

Generalized symmetries of an \U0001d4dd = 1 supersymmetric Boiti–Leon–Manna–Pempinelli system**Project supported by the National Natural Science Foundation of China (Grant Nos. 11275123, 11175092, 11475052, and 11435005), the Shanghai Knowledge Service Platform for Trustworthy Internet of Things, China (Grant No. ZF1213), and the Talent Fund and K CWong Magna Fund in Ningbo University, China.

The formal series symmetry approach (FSSA), a quite powerful and straightforward method to establish infinitely many generalized symmetries of classical integrable systems, has been successfully extended in the supersymmetric framework to explore series of infinitely many generalized symmetries for supersymmetric systems. Taking the \U0001d4a9 = 1 supersymmetric Boiti–Leon–Manna–Pempinelli system as a concrete example, it is shown that the application of the extended FSSA to this supersymmetric system leads to a set of infinitely many generalized symmetries with an arbitrary function f (t). Some interesting special cases of symmetry algebras are presented, including a limit case f (t) = 1 related to the commutativity of higher order generalized symmetries.

Privacy-Aware Distributed Bayesian Detection

We study the eavesdropping problem in the remotely distributed sensing of a privacy-sensible hypothesis from the Bayesian detection perspective. We consider a parallel distributed detection network where remote decision makers independently make local decisions defined on finite domains and forward them to the fusion center which makes the final decision. An eavesdropper is assumed to intercept a specific set of local decisions to make also a guess on the hypothesis. We propose a novel Bayesian detection-operational privacy metric given by the minimal achievable Bayesian risk of the eavesdropper. Further, we introduce two privacy-aware distributed Bayesian detection formulations, namely the privacy-constrained distributed Bayesian detection problem and the privacy-concerned distributed Bayesian detection problem where the detection performance is optimized under a privacy guarantee constraint and a weighted sum objective of the detection performance and privacy risk is minimized respectively. For an optimal privacy-aware distributed Bayesian detection design, the optimal decision strategy of employing a deterministic likelihood test or a randomized strategy thereof is identified. Further, it is shown that equivalent problems of different formulations always exist and lead to the same optimal privacy-aware distributed Bayesian detection design. The results are illustrated and discussed by numerical examples. The idea of privacy-aware distributed Bayesian detection design provides a novel solution to realize future trustworthy Internet of Things applications.

Blastocystis: Taxonomy, biology and virulence

The unicellular protist Blastocystis has long been an unsolved puzzle for taxonomists, microbiologists and clinicians. Over the years, the organism has been bounced on and off the different branches of the tree of life due the possession of unique phenotypic characters intermediary to different organisms. The organism is polymorphic with only few of forms such as vacuolar, granular, amoeboid, and the cyst form being commonly known. However it could exist in other forms much more frequently than the widely known forms which could be missed by the unaware observer. Certain older concepts in the life cycle of Blastocystis although has been proven wrong are still being followed in various textbooks and other trustworthy internet sources. The causal role of Blastocystis in human disease has long been a subject of controversy. It is widely believed that certain subtypes of the organism are virulent. But this is not so as other factors are also involved in the clinical outcome of the infection. In these contexts, this review intends to shed light on the past misconceptions and the recent findings on the taxonomy, biology and the virulence of this organism.

Editorial: Multi-agent & distributed information security

Information Security (IFS) addresses a sensitive part of information technology where the success of virtually all new technological developments depends on efficient use of automation for human resource management, computer technologies for trustworthy internet, many new communication services and distributed sensor systems for human quality of life and global stability which all heavily depend on our systems and devices working securely and reliably. The level of research activities and rate of publications in this field, however, has been too slow for many decades and never shown any significant development to measure up its importance.

Routing Algorithms Based on Partial Deployment of SAVA Nodes in Trustworthy Internet

Although the fundamental principles of best-effort and destination address based packet forwarding in today's Internet have brought tremendous convenience, the trustworthy issue in Internet is a hot problem since the lack of source IP address checking in most cases makes it easy for the attackers to spoof the source address. Therefore, one challenge in trustworthy Internet is to build a feasible mechanism to verify the source address. Recently, a feasible mechanism called Source Address Validation Architecture (SAVA) has been proposed to specify standardization of methods for building effective source-address validation to ensure that packets forwarded hold authentic source addresses. In SAVA mechanism, if a packet has been recognized as a spoofed source address, it will be dropped by the SAVA router and not be transmitted to the next hop. In our work, we study the routing algorithms based on partial deployment of SAVA nodes in Internet and propose three kinds of routing algorithms, i.e., Shortest-Path Algorithm (SPA), SAVA based Shortest-Path Algorithm (SSPA), and SAVA based Shortest-Path Algorithm with Load Balancing (SSPALB). To the best of our best knowledge, this is the first investigation for SAVA mechanism from the point of routing method. In SPA, the packet will be routed on the shortest path that may not traverse the SAVA node, and then the SAVA requirement may not be ensured. In SSPA, the packet will be routed on the shortest path that must traverse one SAVA node such that the SAVA requirement can be ensured. In SSPALB, the packet will be routed on the shortest path that must traverse one SAVA node at the same time this SAVA node must be the least-load such that the SAVA requirement can be ensured and the load can be more balancing. We simulate an incremental traffic model for the three kinds of routing algorithms to compare the performances of SAVA Satisfactory Degree (SSD) and Load Balancing (LB). Simulation results show that: the SSDs of SSPA and SSPALB can reach 100% while the SSD of SPA is only 20%-30%, which means that SSPA and SSPALB are completely satisfactory for SAVA requirements but SPA cannot; the LB of SSPALB can reach 100% while the LBs of SPA and SSPA are only 70%-80%, which means that SSPALB is more favorable for the load balancing.

The most frequently searched topics were LASIK(laser in-situ Keratomileusis), diabetes, and contraception. 39.6% of them evaluated the Internet health information was reliable and 55.8% of them satisfied with the Internet health information. Conclusion: Universities and their in-campus health centers are needed to offer the trustworthy Internet health informtaion on their official homepages so that the student can refer to the reliable and qualified Internet health information.

New routing algorithms in trustworthy Internet

Since the lack of source IP address checking in today’s Internet makes it easy for the attackers to spoof the source address, the mechanism of Source Address Validation Architecture (SAVA) is proposed for building effective source-address validation to ensure that packets forwarded hold authentic source addresses. In this paper, we study the routing selection in partial deployment of SAVA nodes in the trustworthy Internet. We propose and compare three routing algorithms, i.e., Shortest-Path Algorithm (SPA), SAVA based Shortest-Path Algorithm (SSPA), and SAVA based Shortest-Path Algorithm with Load Balancing (SSPALB). Beside analytical results, we run simulations which met our expectations.

A trustworthy Internet auction model with verifiable fairness

Describes a novel Internet auction model achieving verifiable fairness, a requirement aimed at enhancing the trust of bidders in auctioneers. Distrust in remote auctioneers prevents bidders from participating in Internet auctioning. According to proposed survey reports, this study presents four characteristics that render the Internet untrustworthy for bidders. These intrinsic properties suggest that auction sites not only follow auction policies, but provide customers with evidence validating that the policies are applied fairly. Evidence of verifiable fairness provides bidders with a basis for confidence in Internet auctions. Cryptographic techniques are also applied herein to establish a novel auction model with evidence to manifest and verify every step of the auctioneer. Analysis results demonstrate that the proposed model satisfies various requirements regarding fairness and privacy. Moreover, in the proposed model, the losing bids remain sealed.
