Next Generation Internet (NGI) technology with new communication protocol IPv6 emerges as a potential solution for low-cost and high-speed networks for image data transmission. IPv6 is designed to solve many of the problems of the current version of IP (known as IPv4) with regard to address depletion, security, autoconfiguration, extensibility, and more. We choose CTN (Central Test Node) DICOM software developed by The Mallinckrodt Institute of Radiology to implement IPv6/IPv4 enabled DICOM communication software on different operating systems (Windows/Linux), and used this DICOM software to evaluate the performance of the IPv6/IPv4 enabled DICOM image communication with different security setting and environments. We compared the security communications of IPsec with SSL/TLS on different TCP/IP protocols (IPv6/IPv4), and find that there are some trade-offs to choose security solution between IPsec and SSL/TLS in the security implementation of IPv6/IPv4 communication networks.

Sensors utilize a large number of heterogeneous technologies for a varied set of application environments. The sheer number of devices involved requires that this Internet be the Future Internet, with a core network based on IPv6 and a higher scalability in order to be able to address all the devices, sensors and things located around us. This capability to connect through IPv6 devices, sensors and things is what is defining the so-called Internet of Things (IoT). IPv6 provides addressing space to reach this ubiquitous set of sensors, but legacy technologies, such as X10, European Installation Bus (EIB), Controller Area Network (CAN) and radio frequency ID (RFID) from the industrial, home automation and logistic application areas, do not support the IPv6 protocol. For that reason, a technique must be devised to map the sensor and identification technologies to IPv6, thus allowing homogeneous access via IPv6 features in the context of the IoT. This paper proposes a mapping between the native addressing of each technology and an IPv6 address following a set of rules that are discussed and proposed in this work. Specifically, the paper presents a technology-dependent IPv6 addressing proxy, which maps each device to the different subnetworks built under the IPv6 prefix addresses provided by the internet service provider for each home, building or user. The IPv6 addressing proxy offers a common addressing environment based on IPv6 for all the devices, regardless of the device technology. Thereby, this offers a scalable and homogeneous solution to interact with devices that do not support IPv6 addressing. The IPv6 addressing proxy has been implemented in a multi-protocol card and evaluated successfully its performance, scalability and interoperability through a protocol built over IPv6. PMID:23686145

IPv4-IPv6 transition rolls out numerous challenges to the world of Internet as the Internet is drifting from IPv4 to IPv6. IETF recommends few transition techniques which includes dual stack and translation and tunneling. By means of tunneling the IPv6 packets over IPv4 UDP, Teredo maintains IPv4/IPv6 dual stack node in isolated IPv4 networks behindhand network address translation (NAT). However, the proposed tunneling protocol works with the symmetric and asymmetric NATs. In order to make a Teredo support several symmetric NATs along with several asymmetric NATs, we propose multifarious Sym Teredo (MTS), which is an extension of Teredo with a capability of navigating through several symmetric NATs. The work preserves the Teredo architecture and also offers a backward compatibility with the original Teredo protocol.

DICOM image secure communications with Internet protocols IPv6 and IPv4.
Zhang, Jianguo; Yu, Fenghai; Sun, Jianyong; Yang, Yuanyuan; Liang, Chenwen
2007-01-01
Image-data transmission from one site to another through public network is usually characterized in term of privacy, authenticity, and integrity. In this paper, we first describe a general scenario about how image is delivered from one site to another through a wide-area network (WAN) with security features of data privacy, integrity, and authenticity. Second, we give the common implementation method of the digital imaging and communication in medicine (DICOM) image communication software library with IPv6/IPv4 for high-speed broadband Internet by using open-source software. Third, we discuss two major security-transmission methods, the IP security (IPSec) and the secure-socket layer (SSL) or transport-layer security (TLS), being used currently in medical-image-data communication with privacy support. Fourth, we describe a test schema of multiple-modality DICOM-image communications through TCP/IPv4 and TCP/IPv6 with different security methods, different security algorithms, and operating systems, and evaluate the test results. We found that there are tradeoff factors between choosing the IPsec and the SSL/TLS-based security implementation of IPv6/IPv4 protocols. If the WAN networks only use IPv6 such as in high-speed broadband Internet, the choice is IPsec-based security. If the networks are IPv4 or the combination of IPv6 and IPv4, it is better to use SSL/TLS security. The Linux platform has more security algorithms implemented than the Windows (XP) platform, and can achieve better performance in most experiments of IPv6 and IPv4-based DICOM-image communications. In teleradiology or enterprise-PACS applications, the Linux operating system may be the better choice as peer security gateways for both the IPsec and the SSL/TLS-based secure DICOM communications cross public networks.

Mobile Internet Protocol Version 6 (MIPv6) environments have been developing very rapidly. Many challenges arise with the fast progress of MIPv6 technologies and its environment. Therefore the importance of improving the existing architecture and operations increases. One of the many challenges which need to be addressed is the need for performance improvement to support mobile multicast. Numerous approaches have been proposed to improve mobile multicast performance. This includes Context Transfer Protocol (CXTP), Hierarchical Mobile IPv6 (HMIPv6), Fast Mobile IPv6 (FMIPv6) and Proxy Mobile IPv6 (PMIPv6). This document describes multicast context transfer in hierarchical proxy mobile IPv6 (H-PMIPv6) to provide better multicasting performance in PMIPv6 domain.

This report documents the design of network infrastructure to support testing and demonstrating network-centric operations and command and control of space-based assets, using IPv6 and IPsec. These tests were performed using the Cisco router in Low Earth Orbit (CLEO), an experimental payload onboard the United Kingdom--Disaster Monitoring Constellation (UK-DMC) satellite built and operated by Surrey Satellite Technology Ltd (SSTL). On Thursday, 29 March 2007, NASA Glenn Research Center, Cisco Systems and SSTL performed the first configuration and demonstration of IPsec and IPv6 onboard a satellite in low Earth orbit. IPv6 is the next generation of the Internet Protocol (IP), designed to improve on the popular IPv4 that built the Internet, while IPsec is the protocol used to secure communication across IP networks. This demonstration was made possible in part by NASA s Earth Science Technology Office (ESTO) and shows that new commercial technologies such as mobile networking, IPv6 and IPsec can be used for commercial, military and government space applications. This has direct application to NASA s Vision for Space Exploration. The success of CLEO has paved the way for new spacebased Internet technologies, such as the planned Internet Routing In Space (IRIS) payload at geostationary orbit, which will be a U.S. Department of Defense Joint Capability Technology Demonstration. This is a sanitized report for public distribution. All real addressing has been changed to psueco addressing.

Analysis of Handoff Mechanisms in Mobile IP
NASA Astrophysics Data System (ADS)
Jayaraj, Maria Nadine Simonel; Issac, Biju; Haldar, Manas Kumar
2011-06-01
One of the most important challenges in mobile Internet Protocol (IP) is to provide service for a mobile node to maintain its connectivity to network when it moves from one domain to another. IP is responsible for routing packets across network. The first major version of IP is the Internet Protocol version 4 (IPv4). It is one of the dominant protocols relevant to wireless network. Later a newer version of IP called the IPv6 was proposed. Mobile IPv6 is mainly introduced for the purpose of mobility. Mobility management enables network to locate roaming nodes in order to deliver packets and maintain connections with them when moving into new domains. Handoff occurs when a mobile node moves from one network to another. It is a key factor of mobility because a mobile node can trigger several handoffs during a session. This paper briefly explains on mobile IP and its handoff issues, along with the drawbacks of mobile IP.

Aviation industries in United States and in Europe are undergoing a major paradigm shift in the introduction of new network technologies. In the US, NASA is also actively investigating the feasibility of IPv6 based networks for the aviation needs of the United States. In Europe, the Eurocontrol lead, Internet Protocol for Aviation Exchange (iPAX) Working Group is actively investigating the various ways of migrating the aviation authorities backbone infrastructure from X.25 based networks to an IPv6 based network. For the last 15 years, the global aviation community has pursued the development and implementation of an industry-specific set of communications standards known as the Aeronautical Telecommunications Network (ATN). These standards are now beginning to affect the emerging military Global Air Traffic Management (GATM) community as well as the commercial air transport community. Efforts are continuing to gain a full understanding of the differences and similarities between ATN and Internet architectures as related to Communications, Navigation, and Surveillance (CNS) infrastructure choices. This research paper describes the implementation of the IPv6 test bed at NASA GRC, and Computer Networks & Software, Inc. and these two test beds are interface to Eurocontrol over the IPv4 Internet. This research work looks into the possibility of providing QoS performance for Aviation application in an IPv6 network as is provided in an ATN based network. The test bed consists of three autonomous systems. The autonomous system represents CNS domain, NASA domain and a EUROCONTROL domain. The primary mode of connection between CNS IPv6 testbed and NASA and EUROCONTROL IPv6 testbed is initially a set of IPv6 over IPv4 tunnels. The aviation application under test (CPDLC) consists of two processes running on different IPv6 enabled machines.

Vulnerability Assessment of IPv6 Websites to SQL Injection and Other Application Level Attacks
Cho, Ying-Chiang; Pan, Jen-Yi
2013-01-01
Given the proliferation of internet connected devices, IPv6 has been proposed to replace IPv4. Aside from providing a larger address space which can be assigned to internet enabled devices, it has been suggested that the IPv6 protocol offers increased security due to the fact that with the large number of addresses available, standard IP scanning attacks will no longer become feasible. However, given the interest in attacking organizations rather than individual devices, most initial points of entry onto an organization's network and their attendant devices are visible and reachable through web crawling techniques, and, therefore, attacks on the visible application layer may offer ways to compromise the overall network. In this evaluation, we provide a straightforward implementation of a web crawler in conjunction with a benign black box penetration testing system and analyze the ease at which SQL injection attacks can be carried out.

Integrated Service Provisioning in an Ipv6 over ATM Research Network
DOE Office of Scientific and Technical Information (OSTI.GOV)
Eli Dart; Helen Chen; Jerry Friesen
1999-02-01
During the past few years, the worldwide Internet has grown at a phenomenal rate, which has spurred the proposal of innovative network technologies to support the fast, efficient and low-latency transport of a wide spectrum of multimedia traffic types. Existing network infrastructures have been plagued by their inability to provide for real-time application traffic as well as their general lack of resources and resilience to congestion. This work proposes to address these issues by implementing a prototype high-speed network infrastructure consisting of Internet Protocol Version 6 (IPv6) on top of an Asynchronous Transfer Mode (ATM) transport medium. Since ATM ismore » connection-oriented whereas IP uses a connection-less paradigm, the efficient integration of IPv6 over ATM is especially challenging and has generated much interest in the research community. We propose, in collaboration with an industry partner, to implement IPv6 over ATM using a unique approach that integrates IP over fast A TM hardware while still preserving IP's connection-less paradigm. This is achieved by replacing ATM's control software with IP's routing code and by caching IP's forwarding decisions in ATM's VPI/VCI translation tables. Prototype ''VR'' and distributed-parallel-computing applications will also be developed to exercise the realtime capability of our IPv6 over ATM network.« less

Advanced mobile networking technology applicable to mobile sensor platforms was developed, deployed and demonstrated. A two-tier sensorweb design was developed. The first tier utilized mobile network technology to provide mobility. The second tier, which sits above the first tier, utilizes 6LowPAN (Internet Protocol version 6 Low Power Wireless Personal Area Networks) sensors. The entire network was IPv6 enabled. Successful mobile sensorweb system field tests took place in late August and early September of 2009. The entire network utilized IPv6 and was monitored and controlled using a remote Web browser via IPv6 technology. This paper describes the mobile networking and 6LowPAN sensorweb design, implementation, deployment and testing as well as wireless systems and network monitoring software developed to support testing and validation.

WLCG and IPv6 - The HEPiX IPv6 working group
Campana, S.; K. Chadwick; Chen, G.; ...
2014-06-11
The HEPiX (http://www.hepix.org) IPv6 Working Group has been investigating the many issues which feed into the decision on the timetable for the use of IPv6 (http://www.ietf.org/rfc/rfc2460.txt) networking protocols in High Energy Physics (HEP) Computing, in particular in the Worldwide Large Hadron Collider (LHC) Computing Grid (WLCG). RIPE NCC, the European Regional Internet Registry (RIR), ran out ofIPv4 addresses in September 2012. The North and South America RIRs are expected to run out soon. In recent months it has become more clear that some WLCG sites, including CERN, are running short of IPv4 address space, now without the possibility of applyingmore » for more. This has increased the urgency for the switch-on of dual-stack IPv4/IPv6 on all outward facing WLCG services to allow for the eventual support of IPv6-only clients. The activities of the group include the analysis and testing of the readiness for IPv6 and the performance of many required components, including the applications, middleware, management and monitoring tools essential for HEP computing. Many WLCG Tier 1/2 sites are participants in the group's distributed IPv6 testbed and the major LHC experiment collaborations are engaged in the testing. We are constructing a group web/wiki which will contain useful information on the IPv6 readiness of the various software components and a knowledge base (http://hepix-ipv6.web.cern.ch/knowledge-base). Furthermore, this paper describes the work done by the working group and its future plans.« less

The HEPiX (http://www.hepix.org) IPv6 Working Group has been investigating the many issues which feed into the decision on the timetable for the use of IPv6 (http://www.ietf.org/rfc/rfc2460.txt) networking protocols in High Energy Physics (HEP) Computing, in particular in the Worldwide Large Hadron Collider (LHC) Computing Grid (WLCG). RIPE NCC, the European Regional Internet Registry (RIR), ran out ofIPv4 addresses in September 2012. The North and South America RIRs are expected to run out soon. In recent months it has become more clear that some WLCG sites, including CERN, are running short of IPv4 address space, now without the possibility of applying for more. This has increased the urgency for the switch-on of dual-stack IPv4/IPv6 on all outward facing WLCG services to allow for the eventual support of IPv6-only clients. The activities of the group include the analysis and testing of the readiness for IPv6 and the performance of many required components, including the applications, middleware, management and monitoring tools essential for HEP computing. Many WLCG Tier 1/2 sites are participants in the group's distributed IPv6 testbed and the major LHC experiment collaborations are engaged in the testing. We are constructing a group web/wiki which will contain useful information on the IPv6 readiness of the various software components and a knowledge base (http://hepix-ipv6.web.cern.ch/knowledge-base). This paper describes the work done by the working group and its future plans.

Practical proliferation of Internet of Things (IoT) concept depends upon communication efficiency in the related network. In the paper we outline basic features of wireless communication protocols used in IoT and concentrate on analysing communication overheads. In particular, we discuss the impact of IPv6 packet length on 6LoWPAN network operation with physical and MAC layer defined by IEEE 802.15.4 standard. The presented analysis methodology is useful in estimation of the total goodput (throughput at the application level) and energy consumptions within the whole traffic model which are the crucial features of IoT networks.
S-curve networks and an approximate method for estimating degree distributions of complex networks
NASA Astrophysics Data System (ADS)
Guo, Jin-Li
2010-12-01
In the study of complex networks almost all theoretical models have the property of infinite growth, but the size of actual networks is finite. According to statistics from the China Internet IPv4 (Internet Protocol version 4) addresses, this paper proposes a forecasting model by using S curve (logistic curve). The growing trend of IPv4 addresses in China is forecasted. There are some reference values for optimizing the distribution of IPv4 address resource and the development of IPv6. Based on the laws of IPv4 growth, that is, the bulk growth and the finitely growing limit, it proposes a finite network model with a bulk growth. The model is said to be an S-curve network. Analysis demonstrates that the analytic method based on uniform distributions (i.e., Barabási-Albert method) is not suitable for the network. It develops an approximate method to predict the growth dynamics of the individual nodes, and uses this to calculate analytically the degree distribution and the scaling exponents. The analytical result agrees with the simulation well, obeying an approximately power-law form. This method can overcome a shortcoming of Barabási-Albert method commonly used in current network research.
Integration of FMIPv6 in HMIPv6 to Improve Hand-over Performance

Mobile users move frequently between networks, as they stay connected to the Internet. Thus, as mobility increases across networks, handovers will significantly impact the quality of the connection and user application. Handover performance is very important when evaluating IP mobility protocols. Since handover request are driven by several needs such as cost reduction criteria, network resource optimization and service related requirements. Current works to support seamless mobility in IPv6 network are classified into HMIPv6 and FMIPv6. These two approaches have pros and cons respectively and are being standardized independently in IETF. If one can integrate properly these two approaches, it is expected that the one can get more effective protocols that can provide better handover performance. This paper integrates FHMIPv6 in HMIPv6 (F-HMIPv6) so as to provide effectively fast handover on the hierarchical Mobile IPv6. The simulation performed using Ns-2 extensions to show that a performance of proposed system is better in terms of packet loss and hand-over delay.
CoAP-Based Mobility Management for the Internet of Things
Chun, Seung-Man; Kim, Hyun-Su; Park, Jong-Tae
2015-01-01
Most of the current mobility management protocols such as Mobile IP and its variants standardized by the IETF may not be suitable to support mobility management for Web-based applications in an Internet of Things (IoT) environment. This is because the sensor nodes have limited power capacity, usually operating in sleep/wakeup mode in a constrained wireless network. In addition, sometimes the sensor nodes may act as the server using the CoAP protocol in an IoT environment. This makes it difficult for Web clients to properly retrieve the sensing data from the mobile sensor nodes in an IoT environment. In this article, we propose a mobility management protocol, named CoMP, which can effectively retrieve the sensing data of sensor nodes while they are moving. The salient feature of CoMP is that it makes use of the IETF CoAP protocol for mobility management, instead of using Mobile IP. Thus CoMP can eliminates the additional signaling overhead of Mobile IP, provides reliable mobility management, and prevents the packet loss. CoMP employs a separate location management server to keep track of the location of the mobile sensor nodes. In order to prevent the loss of important sensing data during movement, a holding mode of operation has been introduced. All the signaling procedures including discovery, registration, binding and holding have been designed by extending the IETF CoAP protocol. The numerical analysis and simulation have been done for performance evaluation in terms of the handover latency and packet loss. The results show that the proposed CoMP is superior to previous mobility management protocols, i.e., Mobile IPv4/v6 (MIPv4/v6), Hierarchical Mobile IPv4/v6 (HMIPv4/v6), in terms of the handover latency and packet loss.

Within the coming decade, there will be a dramatic increase in the availability of inexpensive, computationally powerful mobile devices running applications which use the Internet Protocol (IP) to access multimedia services over broad-band wireless connections. To this end, there has been extensive research and standardization in the areas of Mobile IP and IPv6. The purpose of this paper is to apply this work to the issues involved in designing a mobility model able to adapt to different wireless mobile IP scenarios. We describe the usefulness of this model in the 4th generation mobile multimedia systems to come. This new model has been synthesized through a comparative analysis of current mobile IP models where particular attention has been given to the problems of mobile IP handoff and mobility management and their impact on QoS. By applying a unique perspective to these problems, our model is used to set a roadmap for future mobile IPv6 testbed construction.
Evaluating IPv6 Adoption in the Internet
NASA Astrophysics Data System (ADS)
Colitti, Lorenzo; Gunderson, Steinar H.; Kline, Erik; Refice, Tiziana
As IPv4 address space approaches exhaustion, large networks are deploying IPv6 or preparing for deployment. However, there is little data available about the quantity and quality of IPv6 connectivity. We describe a methodology to measure IPv6 adoption from the perspective of a Web site operator and to evaluate the impact that adding IPv6 to a Web site will have on its users. We apply our methodology to the Google Web site and present results collected over the last year. Our data show that IPv6 adoption, while growing significantly, is still low, varies considerably by country, and is heavily influenced by a small number of large deployments. We find that native IPv6 latency is comparable to IPv4 and provide statistics on IPv6 transition mechanisms used.

2013-07-01
The evolution of Internet topology is not always smooth but sometimes with unusual sudden changes. Consequently, identifying patterns of unusual topology evolution is critical for Internet topology modeling and simulation. We analyze IPv6 Internet topology evolution in IP-level graph to demonstrate how it changes in uncommon ways to restructure the Internet. After evaluating the changes of average degree, average path length, and some other metrics over time, we find that in the case of a large-scale growing the Internet becomes more robust; whereas in a top—bottom connection enhancement the Internet maintains its efficiency with links largely decreased.

Chen, Chin-Ling; Cao, Sheng-Lung
Though the technology of IPv6 network has become mature in recent years, it still takes long to dispose IPv6 in an all-round way in the internet. In this research, we have designed an IPv6 multihomed host architecture to connect both IPv6 network and 6to4 network. This paper describes a load balance mechanism that allows applications on multihomed devices to utilize the individual networks efficiently to transmit streams that could be part of a session. We experiment the relevant parameters in the IPv6 testbed environment to demonstrate its effectiveness.

IPv4 network addresses are running out and the deployment of IPv6 networking in many places is now well underway. Following the work of the HEPiX IPv6 Working Group, a growing number of sites in the Worldwide Large Hadron Collider Computing Grid (WLCG) are deploying dual-stack IPv6/IPv4 services. The aim of this is to support the use of IPv6-only clients, i.e. worker nodes, virtual machines or containers. The IPv6 networking protocols while they do contain features aimed at improving security also bring new challenges for operational IT security. The lack of maturity of IPv6 implementations together with the increased complexity of some of the protocol standards raise many new issues for operational security teams. The HEPiX IPv6 Working Group is producing guidance on best practices in this area. This paper considers some of the security concerns for WLCG in an IPv6 world and presents the HEPiX IPv6 working group guidance for the system administrators who manage IT services on the WLCG distributed infrastructure, for their related site security and networking teams and for developers and software engineers working on WLCG applications.

The Internet of Things is a term which has emerged to describe the increase of Internet connectivity of everyday objects. While wireless sensor networks have developed highly energy efficient designs they need a step-change in their interoperability and usability to become more commonly used in Earth Science. IoT techniques can bring many of these advances while reusing some of the technologies developed for low power sensing. Here we concentrate on developing effective use of internet protocols throughout a low power sensor network. This includes 6LowPAN to provide a mesh IPv6 network, 40mW 868 MHz CC1120 radio transceivers to save power but provide kilometre range, a CC2538 ARM® Cortex®-M3 as main processor and CoAP to provide a binary HTTP-like interface to the nodes. We discuss in detail a system we deployed to monitor periglacial, peat and fluvial processes in the Scottish Highlands. The system linked initial nodes 3km away further up the mountain 2km away and used a CoAP GET sequence from a base station in the valley to gather the data. The IPv6 addressing and tunnelling allowed direct connectivity to desktops in Southampton. This provides insights into how the combination of low power techniques and emerging internet standards will bring advantages in interoperability, heterogeneity, usability and maintainability.

The world is rapidly running out of IPv4 addresses; the number of IPv6 end systems connected to the internet is increasing; WLCG and the LHC experiments may soon have access to worker nodes and/or virtual machines (VMs) possessing only an IPv6 routable address. The HEPiX IPv6 Working Group has been investigating, testing and planning for dual-stack services on WLCG for several years. Following feedback from our working group, many of the storage technologies in use on WLCG have recently been made IPv6-capable. This paper presents the IPv6 requirements, tests and plans of the LHC experiments together with the tests performed on the group's IPv6 test-bed. This is primarily aimed at IPv6-only worker nodes or VMs accessing several different implementations of a global dual-stack federated storage service. Finally the plans for deployment of production dual-stack WLCG services are presented.

This paper introduces the common intrusion detection technologies, discusses the work flow of Snort intrusion detection system, and analyzes IPv6 data packet encapsulation and protocol decoding technology. We propose the expanding Snort architecture to support IPv6 intrusion detection in accordance with CIDF standard combined with protocol analysis technology and pattern matching technology, and present its composition. The research indicates that the expanding Snort system can effectively detect various intrusion attacks; it is high in detection efficiency and detection accuracy and reduces false alarm and omission report, which effectively solves the problem of IPv6 intrusion detection.

The usage of the new IPv6 protocol in production is becoming reality in the HEP community and the Computing Centre of the Institute of Physics in Prague participates in many IPv6 related activities. Our contribution presents experience with monitoring in HEPiX distributed IPv6 testbed which includes 11 remote sites. We use Nagios to check availability of services and Smokeping for monitoring the network latency. Since it is not always trivial to setup DNS in a dual stack environment properly, we developed a Nagios plugin for checking whether a domain name is resolvable when using only IP protocol version 6 and only version 4. We will also present local area network monitoring and tuning related to IPv6 performance. One of the most important software for a grid site is a batch system for a job execution. We will present our experience with configuring and running Torque batch system in a dual stack environment. We also discuss the steps needed to run VO specific jobs in our IPv6 testbed.

Today, the exchange of information in the Internet is dominated by the WWW and e-mail. Discussion groups like mailing lists and newsgroups also permit communication in groups. Information retrieval becomes a crucial challenge in using the Internet. In the field of medicine, three more aspects are of special importance: privacy, legal requirements, and the necessity of transferring large amounts of data. For these problems, today's Internet doesn't provide a sufficient solution yet. Future developments will not only improve the existing services, but also lead to fundamental changes in the transfer technologies: Safer data transfer is to be ensured by new encrypting software together with the planned transfer protocol IPv6. Introducing the new transfer mode ATM will lead to better and resource saving transmission. Computer, telephone and TV networks will grow together, resulting in convergence of media.

Fiber optic sensor network is the development trend of fiber senor technologies and industries. In this paper, I will discuss recent research progress on high capacity fiber sensor networks with hybrid multiplexing techniques and their applications in the fields of security monitoring, environment monitoring, Smart eHome, etc. Firstly, I will present the architecture of hybrid multiplexing sensor passive optical network (HSPON), and the key technologies for integrated access and intelligent management of massive fiber sensor units. Two typical hybrid WDM/TDM fiber sensor networks for perimeter intrusion monitor and cultural relics security are introduced. Secondly, we propose the concept of "Microstructure-Optical X Domin Refecltor (M-OXDR)" for fiber sensor network expansion. By fabricating smart micro-structures with the ability of multidimensional encoded and low insertion loss along the fiber, the fiber sensor network of simple structure and huge capacity more than one thousand could be achieved. Assisted by the WDM/TDM and WDM/FDM decoding methods respectively, we built the verification systems for long-haul and real-time temperature sensing. Finally, I will show the high capacity and flexible fiber sensor network with IPv6 protocol based hybrid fiber/wireless access. By developing the fiber optic sensor with embedded IPv6 protocol conversion module and IPv6 router, huge amounts of fiber optic sensor nodes can be uniquely addressed. Meanwhile, various sensing information could be integrated and accessed to the Next Generation Internet.
Implementation of fast handover for proxy mobile IPv6: Resolving out-of-order packets
Anh, Khuong Quoc; Choo, Hyunseung
2017-01-01
Mobile IP allows for location-independent routing of IP datagrams on the Internet. Mobile IP specifies how a mobile node (MN) registers with its home agent and how the home agent routes datagrams to the MN through the tunnel. Current Mobile IP protocols have difficulties meeting the stringent handover delay requirements of future wireless networks. Fast handover for Proxy Mobile IPv6 (FPMIPv6) is used to resolve handover latency and packet loss problems that occur in the Proxy Mobile IPv6 (PMIPv6) protocol. However, while implementing the FPMIPv6 scheme in a testbed, we encounter the out-of-order packet (OoOP) problem. The cause of this problem is the existence of two paths for data transmitted from a correspondent node (CN) to an MN. Since the problem affects the quality of service (QoS) of the network and the performance of the MN, we propose a new scheme using the last packet marker and packet buffering to solve this problem in FPMIPv6. The new Mobile Access Gateway (MAG) can control and deliver the data transmitted via the old path or the new path to an MN in order, using the last packet marker to notify the end of the data delivery in the old path and the packet buffering for holding the data delivered in the new path. We implement both the proposed scheme and FPMIPv6 in a testbed as a real network environment to demonstrate the correctness, cost effectiveness, and performance of the proposed scheme. A performance evaluation reveals that the proposed scheme can handle the OoOP problem efficiently. PMID:28968450

When someone wants to be registered in an institution such as Birth Certificate, School, Higher Education, e-ID card, Tax, BPJS, Bank, Driving License, Passport and others then have to register and do registration one by one and have registration number or account respectively agency. It may be said that everyone is bothered with the registration process, from the moment of birth must be registered to be registered as a resident, to enter the school must also registration, it is considered ineffective and efficient because one must continue to register one by one and there is repetition of ownership registration number which vary each agency. Seeing these problems need to find a solution or attempt how to keep the affairs of registration is not repetitive and quite once and the number applies to all agencies. The presence of the latest technology that IPv6 brings opportunities for the efficiency and effectiveness of the registration system. The method used in this research is the exploration and modeling of system development with NDLC (Network Development Life Cycle) to produce a model to build IPv6 implementation on e-ID card. The results of the study will show that the public has one registration number.

The fraction of Internet traffic carried over IPv6 continues to grow rapidly. IPv6 support from network hardware vendors and carriers is pervasive and becoming mature. A network infrastructure upgrade often offers sites an excellent window of opportunity to configure and enable IPv6. There is a significant overhead when setting up and maintaining dual-stack machines, so where possible sites would like to upgrade their services directly to IPv6 only. In doing so, they are also expediting the transition process towards its desired completion. While the LHC experiments accept there is a need to move to IPv6, it is currently not directly affecting their work. Sites are unwilling to upgrade if they will be unable to run LHC experiment workflows. This has resulted in a very slow uptake of IPv6 from WLCG sites. For several years the HEPiX IPv6 Working Group has been testing a range of WLCG services to ensure they are IPv6 compliant. Several sites are now running many of their services as dual-stack. The working group, driven by the requirements of the LHC VOs to be able to use IPv6-only opportunistic resources, continues to encourage wider deployment of dual-stack services to make the use of such IPv6-only clients viable. This paper presents the working group’s plan and progress so far to allow sites to deploy IPv6-only CPU resources. This includes making experiment central services dual-stack as well as a number of storage services. The monitoring, accounting and information services that are used by jobs also need to be upgraded. Finally the VO testing that has taken place on hosts connected via IPv6-only is reported.
Conducting Clinically Based Intimate Partner Violence Research: Safety Protocol Recommendations.
Anderson, Jocelyn C; Glass, Nancy E; Campbell, Jacquelyn C
Maintaining safety is of utmost importance during research involving participants who have experienced intimate partner violence (IPV). Limited guidance on safety protocols to protect participants is available, particularly information related to technology-based approaches to informed consent, data collection, and contacting participants during the course of a study. The purpose of the article is to provide details on the safety protocol developed and utilized with women receiving care at an urban HIV clinic and who were taking part in an observational study of IPV, mental health symptoms, and substance abuse and their relationship to HIV treatment adherence. The protocol presents the technological strategies to promote safety and allow autonomy in participant decision-making throughout the research process, including Voice over Internet Protocol telephone numbers, and tablet-based eligibility screening and data collection. Protocols for management of participants at risk for suicide and/or intimate partner homicide that included automated high-risk messaging to participants and research staff and facilitated disclosure of risk to clinical staff based on participant preferences are discussed. Use of technology and partnership with clinic staff helped to provide an environment where research regarding IPV could be conducted without undue burden or risk to participants. Utilizing tablet-based survey administration provided multiple practical and safety benefits for participants. Most women who screened into high-risk categories for suicide or intimate partner homicide did not choose to have their results shared with their healthcare providers, indicating the importance of allowing participants control over information sharing whenever possible.

Women experiencing intimate partner violence (IPV) navigate complex, dangerous decisions. Tailored safety information and safety planning, typically provided by domestic violence service providers, can prevent repeat IPV exposure and associated adverse health outcomes; however, few abused women access these services. The Internet represents a potentially innovative way to connect abused women with tailored safety planning resources and information. The purpose of this study was to compare safety and mental health outcomes at baseline, 6 months, and 12 months among abused women randomized to: (1) a tailored, Internet-based safety decision aid; or (2) control website (typical safety information available online). Multistate, community-based longitudinal RCT with one-to-one allocation ratio and blocked randomization. Data were collected March 2011-May 2013 and analyzed June-July 2015. Currently abused Spanish- or English-speaking women (N=720). A tailored Internet-based safety decision aid included priority-setting activities, risk assessment, and tailored feedback and safety plans. A control website offered typical safety information available online. Primary outcomes were decisional conflict, safety behaviors, and repeat IPV; secondary outcomes included depression and post-traumatic stress disorder. At 12 months, there were no significant group differences in IPV, depression, or post-traumatic stress disorder. Intervention women experienced significantly less decisional conflict after one use (β= -2.68, p=0.042) and greater increase in safety behaviors they rated as helpful from baseline to 12 months (12% vs 9%, p=0.033) and were more likely to have left the abuser (63% vs 53%, p=0.008). Women who left had higher baseline risk (14.9 vs 13.1, p=0.003) found more of the safety behaviors they tried helpful (61.1% vs 47.5%, p<0.001), and had greater reductions in psychological IPV ((11.69 vs 7.5, p=0.001) and sexual IPV (2.41 vs 1.25, p=0.001) than women who stayed. Internet-based safety planning represents a promising tool to reduce the public health impact of IPV. Copyright © 2017 American Journal of Preventive Medicine. Published by Elsevier Inc.

The Proxy Mobile IPv6 (PMIPv6) is a network-based mobility management protocol that allows a Mobile Node(MN) connected to the PMIPv6 domain to move from one network to another without changing the assigned IPv6 address. The user authentication procedure in this protocol is not standardized, but many smartcard based authentication schemes have been proposed. Recently, Alizadeh et al. proposed an authentication scheme for the PMIPv6. However, it could allow an attacker to derive an encryption key that must be securely shared between MN and the Mobile Access Gate(MAG). As a result, outsider adversary can derive MN's identity, password and session key. In this paper, we analyze Alizadeh et al.'s scheme regarding security and propose an enhanced authentication scheme that uses a dynamic identity to satisfy anonymity. Furthermore, we use BAN logic to show that our scheme can successfully generate and communicate with the inter-entity session key.

The IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) has been recently developed by the Internet Engineering Task Force (IETF). Given its crucial role in enabling the Internet of Things, a significant amount of research effort has already been devoted to RPL. However, the RPL network convergence process has not yet been investigated in detail. In this paper we study the influence of the main RPL parameters and mechanisms on the network convergence process of this protocol in IEEE 802.15.4 multihop networks. We also propose and evaluate a mechanism that leverages an option available in RPL for accelerating the network convergence process. We carry out extensive simulations for a wide range of conditions, considering different network scenarios in terms of size and density. Results show that network convergence performance depends dramatically on the use and adequate configuration of key RPL parameters and mechanisms. The findings and contributions of this work provide a RPL configuration guideline for network convergence performance tuning, as well as a characterization of the related performance trade-offs.

Neighbor discovery protocol (NDP) is the underlying protocol in the IPv6 protocol, which is mainly used to solve the problem of interconnection between nodes on the same link. But with wide use of IPV6, NDP becomes the main objects of a variety of attacks due to a lack of security mechanism. The paper introduces the working principle of the NDP and methods of how the SEND protocol to enhance NDP security defense. It also analyzes and summarizes the security threats caused by the defects of the protocol itself. On the basis of the SEND protocol, the NDP data packet structure is modified to enhance the security of the SEND. An improved NDP cheating defense technology is put forward to make up the defects of the SEND protocol which can't verify the correctness of the public key and cannot bind the MAC address.
Reducing the Handover Delay in FMIPv6 Using Proactive Care-of Address Scheme
NASA Astrophysics Data System (ADS)
Li, Yong; Jin, Depeng; Su, Li; Zeng, Lieguang
To deal with the increasing number of mobile devices accessing the Internet and the increasing demands of mobility management, IETF has proposed Mobile IPv6 and its fast handover protocol FMIPv6. In FMIPv6, the possibility of Care-of Address (CoA) collision and the time for Return Routability (RR) procedure result in long handover delay, which makes it unsuitable for real-time applications. In this paper, we propose an improved handover scheme for FMIPv6, which reduces the handover delay by using proactive CoA acquisition, configuration and test method. In our proposal, collision-free CoA is proactively prepared, and the time for RR procedure does not contribute to the handover delay. Furthermore, we analyze our proposal's benefits and overhead tradeoff. The numerical results demonstrate that it outperforms the current schemes, such as FMIPv6 and enhanced FMIPv6, on the aspect of handover delay and packet transmission delay.

Recent research suggests that men who have sex with men (MSM) experience intimate partner violence (IPV) at significantly higher rates than heterosexual men. Few studies, however, have investigated implications of heterosexist social pressures - namely, homophobic discrimination, internalized homophobia, and heterosexism - on risk for IPV among MSM, and no previous studies have examined cross-national variations in the relationship between IPV and social pressure. This paper examines reporting of IPV and associations with social pressure among a sample of internet-recruited MSM in the United States (U.S.), Canada, Australia, the United Kingdom, South Africa, and Brazil. We recruited internet-using MSM from 6 countries through selective banner advertisements placed on Facebook. Eligibility criteria were men age over 18 reporting sex with a man in the past year. Of the 2,771 eligible respondents, 2,368 had complete data and were included in the analysis. Three outcomes were examined: reporting recent experience of physical violence, sexual violence, and recent perpetration of physical violence. The analysis focused on associations between reporting of IPV and experiences of homophobic discrimination, internalized homophobia, and heteronormativity. Reporting of experiencing physical IPV ranged from 5.75% in the U.S. to 11.75% in South Africa, while experiencing sexual violence was less commonly reported and ranged from 2.54% in Australia to 4.52% in the U.S. Perpetration of physical violence ranged from 2.47% in the U.S. to 5.76% in South Africa. Experiences of homophobic discrimination, internalized homophobia, and heteronormativity were found to increase odds of reporting IPV in all countries. There has been little data on IPV among MSM, particularly MSM living in low- and middle-income countries. Despite the lack of consensus in demographic correlates of violence reporting, heterosexist social pressures were found to significantly increase odds of reporting IPV in all countries. These findings show the universality of violence reporting among MSM across countries, and highlight the unique role of heteronormativity as a risk factor for violence reporting among MSM. The results demonstrate that using internet-based surveys to reach MSM is feasible for certain areas, although modified efforts may be required to reach diverse samples of MSM.

In recent years, many scholars have done a great deal of research on the development of Internet of Things and networked physical systems. However, few people have made the detailed visualization of the large-scale communications architecture in the IOT. In fact, the non-uniform technology between IPv6 and access points has led to a lack of broad principles of large-scale communications architectures. Therefore, this paper presents the Uni-IPv6 Access and Information Exchange Method (UAIEM), a new architecture and algorithm that addresses large-scale communications in the IOT.

Computing Center of the Institute of Physics in Prague provides computing and storage resources for various HEP experiments (D0, Atlas, Alice, Auger) and currently operates more than 300 worker nodes with more than 2500 cores and provides more than 2PB of disk space. Our site is limited to one C-sized block of IPv4 addresses, and hence we had to move most of our worker nodes behind the NAT. However this solution demands more difficult routing setup. We see the IPv6 deployment as a solution that provides less routing, more switching and therefore promises higher network throughput. The administrators of the Computing Center strive to configure and install all provided services automatically. For installation tasks we use PXE and kickstart, for network configuration we use DHCP and for software configuration we use CFEngine. Many hardware boxes are configured via specific web pages or telnet/ssh protocol provided by the box itself. All our services are monitored with several tools e.g. Nagios, Munin, Ganglia. We rely heavily on the SNMP protocol for hardware health monitoring. All these installation, configuration and monitoring tools must be tested before we can switch completely to IPv6 network stack. In this contribution we present the tests we have made, limitations we have faced and configuration decisions that we have made during IPv6 testing. We also present testbed built on virtual machines that was used for all the testing and evaluation.

The type 2 component of the oral poliovirus vaccine is targeted for global withdrawal through a switch from the trivalent oral poliovirus vaccine (tOPV) to a bivalent oral poliovirus vaccine (bOPV). The switch is intended to prevent paralytic polio caused by circulating vaccine-derived poliovirus type 2. We aimed to assess the immunogenicity and safety profile of 6 vaccination schedules with different sequential doses of inactivated poliovirus vaccine (IPV), tOPV, or bOPV. A randomized controlled trial was conducted in China in 2015. Healthy newborn babies randomly received one of the following 6 vaccination schedules: cIPV-bOPV-bOPV(I-B-B), cIPV-tOPV-tOPV(I-T-T), cIPV-cIPV-bOPV(I-I-B), cIPV-cIPV-tOPV(I-I-T), cIPV-cIPV-cIPV(I-I-I), or tOPV-tOPV-tOPV(T-T-T). Doses were administered sequentially at 4-6 week intervals after collecting baseline blood samples. Patients were proactively followed up for observation of adverse events after the first dose and 30 days after all doses. The primary study objective was to investigate the immunogenicity and safety profile of different vaccine schedules, evaluated by seroconversion, seroprotection and antibody titer against poliovirus types 1, 2, and 3 in the per-protocol population. Of 600 newborn babies enrolled, 504 (84.0%) were included in the per-protocol population. For type 1 poliovirus, the differences in the seroconversion were 1.17% (95% CI = -2.74%, 5.08%) between I-B-B and I-T-T and 0.00% (95% CI: -6.99%, 6.99%) between I-I-B and I-I-T; for type 3 poliovirus, differences in the seroconversion were 3.49% (95% CI: -1.50%, 8.48%) between I-B-B and I-T-T and -2.32% (95% CI: -5.51%, 0.86%) between I-I-B and I-I-T. The non-inferiority conclusion was achieved in both poliovirus type 1 and 3 with the margin of -10%. Of 24 serious adverse events reported, no one was vaccine-related. The vaccination schedules with bOPV followed by one or 2 doses of IPV were recommended to substitute for vaccinations involving tOPV without compromising the immunogenicity and safety in the Chinese population. The findings will be essential for policy formulation by national and global authorities to facilitate polio elimination.

Network mobility basic support (NEMO BS) protocol is an entire network, roaming as a unit which changes its point of attachment to the Internet and consequently its reachability in the network topology. NEMO BS doesn't provide QoS guarantees to its users same as traditional Internet IP and Mobile IPv6 as well. Typically, all the users will have same level of services without considering about their application requirements. This poses a problem to real-time applications that required QoS guarantees. To gain more effective control of the network, incorporated QoS is needed. Within QoS-enabled network the traffic flow can be distributed to various priorities. Also, the network bandwidth and resources can be allocated to different applications and users. Internet Engineering Task Force (IETF) working group has proposed several QoS solutions for static network such as IntServ, DiffServ and MPLS. These QoS solutions are designed in the context of a static environment (i.e. fixed hosts and networks). However, they are not fully adapted to mobile environments. They essentially demands to be extended and adjusted to meet up various challenges involved in mobile environments. With existing QoS mechanisms many proposals have been developed to provide QoS for individual mobile nodes (i.e. host mobility). In contrary, research based on the movement of the whole mobile network in IPv6 is still undertaking by the IETF working groups (i.e. network mobility). Few researches have been done in the area of providing QoS for roaming networks. Therefore, this paper aims to review and investigate (previous /and current) related works that have been developed to provide QoS in mobile network. Consequently, a new proposed scheme will be introduced to enhance QoS within NEMO environment, achieving by which seamless mobility to users of mobile network node (MNN).
ESS-FH: Enhanced Security Scheme for Fast Handover in Hierarchical Mobile IPv6
NASA Astrophysics Data System (ADS)
You, Ilsun; Lee, Jong-Hyouk; Sakurai, Kouichi; Hori, Yoshiaki
Fast Handover for Hierarchical Mobile IPv6 (F-HMIPv6) that combines advantages of Fast Handover for Mobile IPv6 (FMIPv6) and Hierarchical Mobile IPv6 (HMIPv6) achieves the superior performance in terms of handover latency and signaling overhead compared with previously developed mobility protocols. However, without being secured, F-HMIPv6 is vulnerable to various security threats. In 2007, Kang and Park proposed a security scheme, which is seamlessly integrated into F-HMIPv6. In this paper, we reveal that Kang-Park's scheme cannot defend against the Denial of Service (DoS) and redirect attacks while largely relying on the group key. Then, we propose an Enhanced Security Scheme for F-HMIPv6 (ESS-FH) that achieves the strong key exchange and the key independence as well as addresses the weaknesses of Kang-Park's scheme. More importantly, it enables fast handover between different MAP domains. The proposed scheme is formally verified based on BAN-logic, and its handover latency is analyzed and compared with that of Kang-Park's scheme.

Yan, Shi; Jiayin, Cheng; Shanzhi, Chen
A flatter architecture is one of the trends of mobile Internet. Traditional centralized mobility management mechanism faces the challenges such as scalability and UE reachability. A MIPv6 based distributed mobility management mechanism is proposed in this paper. Some important network entities and signaling procedures are defined. UE reachability is also considered in this paper through extension to DNS servers. Simulation results show that the proposed approach can overcome the scalability problem of the centralized scheme.

This study describes the associations between intimate partner violence (IPV) and HIV risk among urban, predominantly minority women. Interviews were conducted with 1,590 women, predominantly African American and Latina, attending hospital-based health care clinics. Approximately 1 in 5 women reported experiencing IPV in their current primary heterosexual relationships; about 1 in 8 women reported experiencing IPV in the preceding 6 months. Compared to women who reported no IPV in their primary relationships, women reporting past or current IPV perpetrated by their primary partners were more likely to report having multiple sexual partners, a past or current sexually transmitted infection (STI), inconsistent use or nonuse of condoms, and a partner with known HIV risk factors. These findings indicate that urban minority women experiencing IPV are at elevated risk for HIV infection, results that carry important implications in the efforts to improve HIV and IPV risk assessment protocols and intervention/prevention strategies for women in primary health care settings.

Cost and supply constraints are key challenges in the use of inactivated polio vaccine (IPV). Dose reduction through adsorption to aluminium hydroxide (Al) is a promising option, and establishing its effectiveness in the target population is a crucial milestone in developing IPV-Al. The aim of this clinical trial was to show the non-inferiority of three IPV-Al vaccines to standard IPV. In this phase 2, non-inferiority, observer-blinded, randomised, controlled, single-centre trial in the Dominican Republic, healthy infants aged 6 weeks, not previously polio vaccinated, were allocated after computer-generated randomisation by block-size of four, to receive one of four IPV formulations (three-times reduced dose [1/3 IPV-Al], five-times reduced dose [1/5 IPV-Al], ten-times reduced dose [1/10 IPV-Al], or IPV) intramuscularly in the thigh at 6, 10, and 14 weeks of age. The primary outcome was seroconversion for poliovirus types 1, 2, and 3 with titres more than or equal to four-fold higher than the estimated maternal antibody titre and more than or equal to 8 after three vaccinations. Non-inferiority was concluded if the lower two-sided 90% CI of the seroconversion rate difference between IPV-Al and IPV was greater than -10%. The safety analyses were based on the safety analysis set (randomly assigned participants who received at least one trial vaccination) and the immunogenicity analyses were based on the per-protocol population. This study is registered with ClinicalTrials.gov registration, number NCT02347423. Between Feb 2, 2015, and Sept 26, 2015, we recruited 824 infants. The per-protocol population included 820 infants; 205 were randomly assigned to receive 1/3 IPV-Al, 205 to receive 1/5 IPV-Al, 204 to receive 1/10 IPV-Al, and 206 to receive IPV. The proportion of individuals meeting the primary endpoint of seroconversion for poliovirus types 1, 2, and 3 was already high for the three IPV-Al vaccines after two vaccinations, but was higher after three vaccinations (ie, after completion of the expanded programme of immunisation schedule): 1/3 IPV-Al 98·5% (n=202, type 1), 97·6% (n=200; type 2), and 99·5% (n=204, type 3); 1/5 IPV-Al: 99·5% (n=204, type 1), 96·1% (n=197, type 2), and 98·5% (n=202, type 3); and 1/10 IPV-Al: 98·5% (n=201, type 1), 94·6% (n=193, type 2), and 99·5% (n=203, type 3). All three IPV-Al were non-inferior to IPV, with absolute differences in percentage seroconversion for each poliovirus type being greater than -10% (1/3 IPV-Al type 1, -1·46 [-3·60 to 0·10], type 2, -0·98 [-3·62 to 1·49], and type 3, -0·49 [-2·16 to 0·86]; 1/5 IPV-Al type 1, -0·49 [-2·16 to 0·86], type 2, -2·45 [-5·47 to 0·27], and type 3, -1·46 [-3·60 to 0·10]; and 1/10 IPV-Al type 1, -1·47 [-3·62 to 0·10], type 2, -3·94 [-7·28 to -0·97], and type 3, -0·49 [-2·17 to 0·86]). Three serious adverse events occurred that were unrelated to the vaccine. The lowest dose (1/10 IPV-Al) of the vaccine performed well both after two and three doses. Based on these results, this new vaccine is under investigation in phase 3 trials. Bill & Melinda Gates Foundation. Copyright © 2017 The Author(s). Published by Elsevier Ltd.

IEEE 802.16m is an advanced air interface standard which is under development for IMT-Advanced systems, known as 4G systems. IEEE 802.16m is designed to provide a high data rate and a Quality of Service (QoS) level in order to meet user service requirements, and is especially suitable for mobilized environments. There are several factors that have great impact on such requirements. As one of the major factors, we mainly focus on latency issues. In IEEE 802.16m, an enhanced layer 2 handover scheme, described as Entry Before Break (EBB) was proposed and adopted to reduce handover latency. EBB provides significant handover interruption time reduction with respect to the legacy IEEE 802.16 handover scheme. Fast handovers for mobile IPv6 (FMIPv6) was standardized by Internet Engineering Task Force (IETF) in order to provide reduced handover interruption time from IP layer perspective. Since FMIPv6 utilizes link layer triggers to reduce handover latency, it is very critical to jointly design FMIPv6 with its underlying link layer protocol. However, FMIPv6 based on new handover scheme, EBB has not been proposed. In this paper, we propose an improved cross-layering design for FMIPv6 based on the IEEE 802.16m EBB handover. In comparison with the conventional FMIPv6 based on the legacy IEEE 802.16 network, the overall handover interruption time can be significantly reduced by employing the proposed design. Benefits of this improvement on latency reduction for mobile user applications are thoroughly investigated with both numerical analysis and simulation on various IP applications.

Recent advances in electronic and automotive industries as well as in wireless telecommunication technologies have drawn a new picture where each vehicle became “fully networked”. Multiple stake-holders (network operators, drivers, car manufacturers, service providers, etc.) will participate in this emerging market, which could grow following various models. To free the market from technical constraints, it is important to return to the basics of the Internet, i.e., providing embarked devices with a fully operational Internet connectivity (IPv6).

In adults with a tetanus-prone injury, combined vaccines such as Tdap-IPV (REPEVAX®) can boost immunity against several diseases simultaneously. This Phase IIIb, parallel-group, open-label trial compared antibody responses to Tdap-IPV and tetanus monovalent vaccine (TMV; Vaccin Tétanique Pasteur® or Tetavax®) against tetanus toxoid 10 and 28 d post-vaccination. Between July and December 2009, four centers in France and five in Germany recruited healthy adults who had received a tetanus-containing vaccine 5−10 y previously. Participants were randomized 1:1 to receive at the first visit a single dose (0.5 mL) of Tdap-IPV or TMV, with follow-up visits at Day 10 and Day 28. Outcomes: per protocol (PP) population immunogenicity at Day 10 (primary) and at Day 28 (secondary); safety throughout the study. Of 456 adults randomized, 223 received Tdap-IPV and 233 received TMV (PP population: 183 and 199 participants, respectively). All participants receiving Tdap-IPV and 99.0% receiving TMV had an anti-tetanus antibody concentration ≥ 0.1 IU/mL, confirming non-inferiority of Tdap-IPV to TMV (95% confidence interval of the difference: –1.2, 3.6). Number of adverse events reported was comparable in each group. Injection-site reactions were reported by 76.6% participants receiving Tdap-IPV and 74.6% receiving TMV. Systemic events (e.g., malaise, myalgia and headache) were reported in 47.7% and 39.7% of the Tdap-IPV and the TMV groups, respectively. Tdap-IPV is effective and well-tolerated for use in the management of tetanus-prone injuries in emergency settings in persons for whom a booster against diphtheria, pertussis and poliomyelitis is also needed.

Communication techniques and challenges for wireless food quality monitoring

2014-01-01
Remote measurement of product core temperature is an important prerequisite to improve the cool chain of food products and reduce losses. This paper examines and shows possible solutions to technical challenges that still hinder practical applications of wireless sensor networks in the field of food transport supervision. The high signal attenuation by water-containing products limits the communication range to less than 0.5 m for the commonly used 2.4 GHz radio chips. By theoretical analysis of the dependency of signal attenuation on the operating frequency, we show that the signal attenuation can be largely reduced by the use of 433 MHz or 866 MHz devices, but forwarding of messages over multiple hops inside a sensor network is mostly unavoidable to guarantee full coverage of a packed container. Communication protocols have to provide compatibility with widely accepted standards for integration into the global Internet, which has been achieved by programming an implementation of the constrained application protocol for wireless sensor nodes and integrating into IPv6-based networks. The sensor's battery lifetime can be extended by optimizing communication protocols and by in-network pre-processing of the sensor data. The feasibility of remote freight supervision was demonstrated by our full-scale ‘Intelligent Container’ prototype. PMID:24797133

Remote measurement of product core temperature is an important prerequisite to improve the cool chain of food products and reduce losses. This paper examines and shows possible solutions to technical challenges that still hinder practical applications of wireless sensor networks in the field of food transport supervision. The high signal attenuation by water-containing products limits the communication range to less than 0.5 m for the commonly used 2.4 GHz radio chips. By theoretical analysis of the dependency of signal attenuation on the operating frequency, we show that the signal attenuation can be largely reduced by the use of 433 MHz or 866 MHz devices, but forwarding of messages over multiple hops inside a sensor network is mostly unavoidable to guarantee full coverage of a packed container.

NEMO BSP is an upgraded addition to Mobile IPv6 (MIPv6). As MIPv6 and its enhancements (i.e. HMIPv6) possess some limitations like higher handoff latency, packet loss, NEMO BSP also faces all these shortcomings by inheritance. Network Mobility (NEMO) is involved to handle the movement of Mobile Router (MR) and it's Mobile Network Nodes (MNNs) during handoff. Hence it is essential to upgrade the performance of mobility management protocol to obtain continuous session connectivity with lower delay and packet loss in NEMO environment. The completion of handoff process in NEMO BSP usually takes longer period since MR needs to register its single primary care of address (CoA) with home network that may cause performance degradation of the applications running on Mobile Network Nodes. Moreover, when a change in point of attachment of the mobile network is accompanied by a sudden burst of signaling messages, "Signaling Storm" occurs which eventually results in temporary congestion, packet delays or even packet loss. This effect is particularly significant for wireless environment where a wireless link is not as steady as a wired link since bandwidth is relatively limited in wireless link. Hence, providing continuous Internet connection without any interruption through applying multihoming technique and route optimization mechanism in NEMO are becoming the center of attention to the current researchers. In this paper, we propose a handoff cost model to compare the signaling cost of MM-NEMO with NEMO Basic Support Protocol (NEMO BSP) and HMIPv6.The numerical results shows that the signaling cost for the MM-NEMO scheme is about 69.6 % less than the NEMO-BSP and HMIPv6.

With the expansion of women's roles in the military, the number of female service members and veterans has increased. Considerable knowledge about intimate partner violence (IPV) in civilian couples exists but little is known about IPV among female service members and veterans. Prevalence rates of IPV range from 17% to 39% for female service members, and 21.9% to 74% for veterans. Most service members and veterans indicated using the Internet at least occasionally and expressed willingness to seek information about services via the Internet. Informed by data, we conducted a systematic review of military (Army, Navy, Air Force, and Marine Corps) and non-military (Veterans Affairs and Google) websites to explore the availability and presentation of information and resources related to IPV. The websites search revealed a variety of resources and information available, and important differences between sites with regard to what and how information is presented. Implications for practice and further research are discussed.

2011-01-01
IP based Wireless Sensor Networks (IP-WSNs) are gaining importance for their broad range of applications in health-care, home automation, environmental monitoring, industrial control, vehicle telematics and agricultural monitoring. In all these applications, mobility in the sensor network with special attention to energy efficiency is a major issue to be addressed. Host-based mobility management protocols are not suitable for IP-WSNs because of their energy inefficiency, so network based mobility management protocols can be an alternative for the mobility supported IP-WSNs. In this paper we propose a network based mobility supported IP-WSN protocol called Sensor Proxy Mobile IPv6 (SPMIPv6). We present its architecture, message formats and also evaluate its performance considering signaling cost, mobility cost and energy consumption. Our analysis shows that with respect to the number of IP-WSN nodes, the proposed scheme reduces the signaling cost by 60% and 56%, as well as the mobility cost by 62% and 57%, compared to MIPv6 and PMIPv6, respectively. The simulation results also show that in terms of the number of hops, SPMIPv6 decreases the signaling cost by 56% and 53% as well as mobility cost by 60% and 67% as compared to MIPv6 and PMIPv6 respectively. It also indicates that proposed scheme reduces the level of energy consumption significantly. PMID:22319386

The development of a Sabin strain-based inactivated poliovirus vaccine (Sabin-IPV) is imperative to protecting against vaccine-associated paralytic poliomyelitis in developing countries. In this double-blinded, parallel-group, noninferiority trial, eligible infants aged 60-90 days were randomly assigned in a ratio of 1:1 to receive either 3 doses of Sabin-IPV or Salk strain-based IPV (Salk-IPV) at 30-day intervals and a booster at the age of 18 months. Immunogenicity and safety were assessed on the basis of a protocol. Of 1438 infants, 1200 eligible infants were recruited and received either Sabin-IPV or Salk-IPV. From the Sabin-IPV and Salk-IPV groups, 570 and 564 infants, respectively, completed the primary immunization and formed the per-protocol population. The seroconversion rates of the participants who received Sabin-IPV were 100%, 94.9%, and 99.0% (types I, II, and III, respectively), and those of the participants who received Salk-IPV were 94.7%, 91.3%, and 97.9% 1 month after the completion of primary immunization. An anamnestic response for poliovirus types I, II, and III was elicited by a booster in both groups. Except in the case of fever, other adverse events were similar between the 2 groups. The immune response induced by Sabin-IPV was not inferior to that established with Salk-IPV. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

Violence against women is a global public health problem with negative effects on physical, mental, and reproductive health. The World Health Organization (WHO) has identified intimate partner violence (IPV) and sexual violence (SV) as major targets for prevention and amelioration and recently developed clinical and policy guidelines to assist healthcare providers. This project was undertaken to determine the 2013 baseline national policies and clinical guidelines on IPV and SV within the Latin American and Caribbean (LAC) region to identify strengths and gaps requiring action. Each Pan American Health Organization/World Health Organization Regional Office for the Americas (PAHO/WHO) country focal point was contacted to request their current national policy and clinical guidelines (protocol) on IPV/SV. We augmented this by searching the internet and the United Nations Women website. Each country's policy and clinical guideline (where available) was reviewed and entered into a scoring matrix based on WHO Clinical and Policy Guidelines. A total score for each heading and subheading was developed by adding positive responses to identify LAC regional strengths and gaps. We obtained 15 national policies and 12 national clinical guidelines (protocols) from a total of 18 countries ("response" rate 66.7%). National policies were comprehensive in terms of physical, emotional, and sexual violence and recommended good intersectoral collaboration. The greatest gap was in the training of health-care providers. National Guidelines for women-centered care for IPV/SV survivors were strong in the vital areas of privacy, confidentiality, danger assessment, safety planning, and supportive reactions to disclosure. The largest gaps noted were again in training healthcare professionals and strengthening monitoring and evaluation of services. Baseline measurement of policy and clinical guidelines for IPV/SV in LAC PAHO/WHO member countries at the time of issuing the 2013 WHO Clinical and Policy Guidelines reveals some important strengths, but also serious gaps that need to be addressed. The most pressing needs are for concerted training initiatives for healthcare providers and strengthening multisectoral monitoring and evaluation of services. A future evaluation of national policies, clinical guidelines, monitoring and evaluation will need to be conducted to measure the progress of the required scaling-up process.

In 2014, 2 studies showed that inactivated poliovirus vaccine (IPV) boosts intestinal immunity in children previously immunized with oral poliovirus vaccine (OPV). As a result, IPV was introduced in mass campaigns to help achieve polio eradication. We conducted an open-label, randomized, controlled trial to assess the duration of the boost in intestinal immunity following a dose of IPV given to OPV-immunized children. Nine hundred healthy children in Vellore, India, aged 1-4 years were randomized (1:1:1) to receive IPV at 5 months (arm A), at enrollment (arm B), or no vaccine (arm C). The primary outcome was poliovirus shedding in stool 7 days after bivalent OPV challenge at 11 months. For children in arms A, B, and C, 284 (94.7%), 297 (99.0%), and 296 (98.7%), respectively, were eligible for primary per-protocol analysis. Poliovirus shedding 7 days after challenge was less prevalent in arms A and B compared with C (24.6%, 25.6%, and 36.4%, respectively; risk ratio 0.68 [95% confidence interval: 0.53-0.87] for A versus C, and 0.70 [0.55-0.90] for B versus C). Protection against poliovirus remained elevated 6 and 11 months after an IPV boost, although at a lower level than reported at 1 month. CTRI/2014/09/004979. © The Author 2016.

Energy internet is a kind of power sharing network, which can realize the bidirectional flow of energy information on the basis of the existing power grid. It puts forward higher requirements for reliability and controllability of information communication, and all kinds of business QoS of the backbone network. So the research of business QoS and trustworthy and controllable strategies mechanism have an important significance for the development of energy internet. This paper mainly studies how to use the software defined network (SDN) to achieve business QoS, and provide QoS support for all kinds of business of the energy internet. Combined with the current development situation of the energy internet in our country, this paper researches the trustworthy and controllable strategies mechanism for energy internet, and proposes the transition scheme of the IPv6 credible network architecture based on SDN. This coordinates the contradiction between the growing demand for energy internet applications and the limitations of the energy internet technology itself.

Despite the existence of ample literature dealing, on the one hand, with the integration of innovations within health systems and team learning, and, on the other hand, with different aspects of the detection and management of intimate partner violence (IPV) within healthcare facilities, research that explores how health innovations that go beyond biomedical issues-such as IPV management-get integrated into health systems, and that focuses on healthcare teams' learning processes is, to the best of our knowledge, very scarce if not absent. This realist evaluation protocol aims to ascertain: why, how, and under what circumstances primary healthcare teams engage (if at all) in a learning process to integrate IPV management in their practices; and why, how, and under what circumstances team learning processes lead to the development of organizational culture and values regarding IPV management, and the delivery of IPV management services. This study will be conducted in Spain using a multiple-case study design. Data will be collected from selected cases (primary healthcare teams) through different methods: individual and group interviews, routinely collected statistical data, documentary review, and observation. Cases will be purposively selected in order to enable testing the initial middle-range theory (MRT). After in-depth exploration of a limited number of cases, additional cases will be chosen for their ability to contribute to refining the emerging MRT to explain how primary healthcare learn to integrate intimate partner violence management. Evaluations of health sector responses to IPV are scarce, and even fewer focus on why, how, and when the healthcare services integrate IPV management. There is a consensus that healthcare professionals and healthcare teams play a key role in this integration, and that training is important in order to realize changes. However, little is known about team learning of IPV management, both in terms of how to trigger such learning and how team learning is connected with changes in organizational culture and values, and in service delivery. This realist evaluation protocol aims to contribute to this knowledge by conducting this project in a country, Spain, where great endeavours have been made towards the integration of IPV management within the health system.

In recent years, IoT (Internet of Things) technologies have seen great advances, particularly, the IPv6 Routing Protocol for Low-power and Lossy Networks (RPL), which provides a powerful and flexible routing framework that can be applied in a variety of application scenarios. In this context, as an important role of IoT, Wireless Sensor Networks (WSNs) can utilize RPL to design efficient routing protocols for a specific application to increase the ubiquity of networks with resource-constrained WSN nodes that are low-cost and easy to deploy. In this article, our work starts with the description of Agricultural Low-power and Lossy Networks (A-LLNs) complying with the LLN framework, and to clarify the requirements of this application-oriented routing solution. After a brief review of existing optimization techniques for RPL, our contribution is dedicated to a Scalable Context-Aware Objective Function (SCAOF) that can adapt RPL to the environmental monitoring of A-LLNs, through combining energy-aware, reliability-aware, robustness-aware and resource-aware contexts according to the composite routing metrics approach. The correct behavior of this enhanced RPL version (RPAL) was verified by performance evaluations on both simulation and field tests. The obtained experimental results confirm that SCAOF can deliver the desired advantages on network lifetime extension, and high reliability and efficiency in different simulation scenarios and hardware testbeds.

Pertussis in adults and adolescents could be reduced by replacing traditional tetanus and diphtheria (Td) boosters with reduced-antigen-content diphtheria-tetanus-acellular pertussis (dTpa) vaccines. This study evaluated the administration of dTpa-IPV (dTpa-inactivated poliovirus) in adults ten years after they received a booster dose of either dTpa-IPV, dTpa+IPV or Td-IPV in trial NCT01277705. Open multicentre, phase IV study (www.clinicaltrials.govNCT01323959) in which healthy adults, who had received a previous dose of dTpa-IPV, dTpa+IPV or Td-IPV ten years earlier, received a single decennial booster dose of dTpa-IPV (Boostrix-polio, GlaxoSmithKline Vaccines). Blood samples were collected before and one month after booster vaccination. Antibody concentrations against all vaccine antigens were measured and reactogenicity and safety were assessed. A total of 211 subjects (mean age 50.3 years) received vaccination of whom 201 were included in the according-to-protocol cohort for immunogenicity. Before the decennial dTpa-IPV booster, ≥71.0% subjects were seroprotected/seropositive against all vaccine antigens. One month after the booster dose, all subjects were seroprotected against tetanus and poliovirus types 2 and 3; ≥95.7% subjects were seroprotected against diphtheria and ≥98.3% against poliovirus type 1. Anti-pertussis booster responses for the various antigens were observed in ≥76.5% (pertussis toxoid; PT), ≥85.1% (filamentous haemagglutinin; FHA) and ≥63.2% (pertactin; PRN) of subjects. During the 4-day follow-up, the overall incidence of local AEs was 71.6%, 75.0% and 72.2% in dTpa-IPV, dTpa+IPV and Td-IPV groups, respectively. Pain was the most frequent solicited local adverse event (AE; ≥62.7% subjects) and fatigue the most frequent solicited general AE (≥18.5%). No serious AEs were reported during the study. A booster dose of dTpa-IPV was immunogenic and well tolerated in adults who had received a booster dose of either dTpa-IPV, dTpa+IPV or Td-IPV, ten years previously and supports the repeated administration of dTpa-IPV.

[Detection of intimate partner violence in primary care and related factors].
Rodríguez-Blanes, Gloria M; Vives-Cases, Carmen; Miralles-Bueno, Juan José; San Sebastián, Miguel; Goicolea, Isabel
Intimate partner violence (IPV) against women is a significant public health and human rights problem. Primary care professionals play a key role in detecting and addressing this issue. The aim of this study is to determine the frequency of IPV and its associated factors in primary care by means of a screening questionnaire and to describe the main actions taken in identified cases. Cross-sectional study in 15 health centres in four autonomous regions of Spain with a total of 265 health professionals. The information was collected through the self-administered PREMIS questionnaire (Physician Readiness to Manage Intimate Partner Violence Survey), which includes variables concerning screening questions, sociodemographic factors, level of training/knowledge about IPV, perceptions and actions. A descriptive and analytical study was conducted. 67.2% of participants said they ask about IPV during consultations. The most frequent actions were: referring patients to other departments, individual counselling and information delivery. ≥21hours of training, an advanced training level, knowledge of policies and programmes and the implementation of an appropriate protocol and reference resources were all factors that increased the likelihood of investigating IPV. The asking of questions increases in line with professionals' perceived level of training in IPV and the provision of a case management protocol. Two thirds of health professional respondents said they inquire about IPV. Given the influence of training in IPV and awareness of the resources to address the issue, it is essential to continue investing in the IPV training of healthcare personnel. Copyright © 2017 SESPAS.

The adverse effects of intimate partner violence (IPV) on mental health are well-established, except in the cases of psychological abuse and men's victimization. This research study examines the prevalence and the independent contribution of psychological IPV on mental health for both genders. The initial sample comprises 661 college students from a Portuguese public university, who completed an e-survey. Statistical analysis focused on a subsample (n=364), 23% of which were men, after removing cases of physical and/or sexual abuse. A total of 75% of men and 72% of women reported lifetime psychological victimization and no differences were found for sociodemographic factors, including gender. However, women reported significantly more instigations of psychological abusive acts (OR =5.41, 95% CI=1.88-15.55). Multivariate linear regression models revealed that post-traumatic stress symptoms-PTSS (β=.51; p<.001), depression (β=.34; p<.001) and anxiety (β=.22; p<.001)-were predicted by psychological IPV. The strongest relationship was established between psychological IPV and PTSS, and the final model accounts for 28.6% of the variance (F(6357)=23.86, p<.001). This article provides an empirical basis to recognize the unique and serious impact of psychological IPV on mental health, and recommends screening psychological IPV as part of the clinical routine, developing a gender-inclusive approach, and implementing evidence-based protocols tailored to the needs of these victims.

DNS is a critical component of the Internet. It maps domain names to IP addresses and serves as a distributed database for various other applications, including mail, Web, and spam filtering. This paper examines DNS zones in the Internet for diversity, adoption rates of new technologies, and prevalence of configuration issues. To gather data, we sweep 60% of the Internet's domains in June - August 2007 for zone transfers. 6.6% of them allow us to transfer their complete information. Surprisingly, this includes a large fraction of the domains deploying DNSSEC. We find that DNS zones vary significantly in size andmore » some span many ASes. Also, while anti-spam technologies appear to be getting deployed, the adoption rates of DNSSEC and IPv6 continue to be low. Finally, we also find that carelessness in handing DNS records can lead to reduced availability of name servers, email, and Web servers. This also undermines anti-spam efforts and the efforts to shut down phishing sites or to contain malware infections.« less

Background Intimate partner violence (IPV) can result in significant harm to women and families and is especially prevalent when women are pregnant or recent mothers. Maternal and child health nurses (MCHN) in Victoria, Australia are community-based nurse/midwives who see over 95% of all mothers with newborns. MCHN are in an ideal position to identify and support women experiencing IPV, or refer them to specialist family violence services. Evidence for IPV screening in primary health care is inconclusive to date. The Victorian government recently required nurses to screen all mothers when babies are four weeks old, offering an opportunity to examine the effectiveness of MCHN IPV screening practices. This protocol describes the development and design of MOVE, a study to examine IPV screening effectiveness and the sustainability of screening practice. Methods/design MOVE is a cluster randomised trial of a good practice model of MCHN IPV screening involving eight maternal and child health nurse teams in Melbourne, Victoria. Normalisation Process Theory (NPT) was incorporated into the design, implementation and evaluation of the MOVE trial to enhance and evaluate sustainability. Using NPT, the development stage combined participatory action research with intervention nurse teams and a systematic review of nurse IPV studies to develop an intervention model incorporating consensus guidelines, clinical pathway and strategies for individual nurses, their teams and family violence services. Following twelve months’ implementation, primary outcomes assessed include IPV inquiry, IPV disclosure by women and referral using data from MCHN routine data collection and a survey to all women giving birth in the previous eight months. IPV will be measured using the Composite Abuse Scale. Process and impact evaluation data (online surveys and key stakeholders interviews) will highlight NPT concepts to enhance sustainability of IPV identification and referral. Data will be collected again in two years. Discussion MOVE will be the first randomised trial to determine IPV screening effectiveness in a community based nurse setting and the first to examine sustainability of an IPV screening intervention. It will further inform the debate about the effectiveness of IPV screening and describe IPV prevalence in a community based post-partum and early infant population.

This systematic review synthesizes 11 studies of health-sector responses to intimate partner violence (IPV) in low- and middle-income countries. The services that were most comprehensive and integrated in their responsiveness to IPV were primarily in primary health and antenatal care settings. Findings suggest that the following facilitators are important: availability of clear guidelines, policies, or protocols; management support; intersectoral coordination with clear, accessible on-site and off-site referral options; adequate and trained staff with accepting and empathetic attitudes toward survivors of IPV; initial and ongoing training for health workers; and a supportive and supervised environment in which to enact new IPV protocols. A key characteristic of the most integrated responses was the connection or "linkages" between different individual factors. Irrespective of their service entry point, what emerged as crucial was a connected systems-level response, with all elements implemented in a coordinated manner. © 2017 The Population Council, Inc.

Proxy Mobile IPv6 is a network-based localized mobility management protocol that supports mobility without mobile nodes' participation in mobility signaling. The details of user authentication procedure are not specified in this standard, hence, many authentication schemes have been proposed for this standard. In 2013, Chuang et al., proposed an authentication method for PMIPv6, called SPAM. However, Chuang et al.'s Scheme protects the network against some security attacks, but it is still vulnerable to impersonation and password guessing attacks. In addition, we discuss other security drawbacks such as lack of revocation procedure in case of loss or stolen device, and anonymity issues of the Chuang et al.'s scheme. We further propose an enhanced authentication method to mitigate the security issues of SPAM method and evaluate our scheme using BAN logic.

Inter-Domain Roaming Mechanism Transparent to Mobile Nodes among PMIPv6 Networks
NASA Astrophysics Data System (ADS)
Park, Soochang; Lee, Euisin; Jin, Min-Sook; Kim, Sang-Ha
In Proxy Mobile IPv6 (PMIPv6), when a Mobile Node (MN) enters a PMIPv6 domain and attaches to an access link, the router on the access link detects attachment of the MN by the link-layer access. All elements of PMIPv6 including the router then provide network-based mobility management service for the MN. If the MN moves to another router in this PMIPv6 domain, the new router emulates attachment to the previous router by providing same network prefix to the MN. In other words, PMIPv6 provides rapid mobility management based on layer-2 attachment and transparent mobility support to the MN by emulating layer-3 attachment with respect to intra-domain roaming. However, when the MN moves to other PMIPv6 domains, although the domains also provide the network-based mobility management service, the MN should exploit the host-based mobility management protocol, i.e. Mobile IPv6 (MIPv6), for the inter-domain roaming. Hence, this letter proposes the rapid and transparent inter-domain roaming mechanism controlled by the networks adopting PMIPv6.

Introduction High intrapatient variability (IPV) in tacrolimus trough levels has been shown to be associated with higher rates of renal transplant failure. There is no consensus on what level of IPV constitutes a risk of graft loss. The establishment of such a threshold could help to guide clinicians in identifying at-risk patients to receive targeted interventions to improve IPV and thus outcomes. Methods and analysis A multicentre Transplant Audit Collaborative has been established to conduct a retrospective study examining tacrolimus IPV and renal transplant outcomes. Patients in receipt of a renal transplant at participating centres between 2009 and 2014 and fulfilling the inclusion criteria will be included in the study. The aim is to recruit a minimum of 1600 patients with follow-up spanning at least 2 years in order to determine a threshold IPV above which a renal transplant recipient would be considered at increased risk of graft loss. The study also aims to determine any national or regional trends in IPV and any demographic associations. Ethics and dissemination Consent will not be sought from patients whose data are used in this study as no additional procedures or information will be required from participants beyond that which would normally take place as part of clinical care. The study will be registered locally in each participating centre in line with local research and development protocols. It is anticipated that the results of this audit will be disseminated locally, in participating NHS Trusts, through national and international meetings and publications in peer-reviewed journals.

Audio computer-assisted self-interviews (ACASIs) have safely and effectively obtained sensitive research data from the general public and have been recommended for use with people with disabilities. However, few studies have used ACASIs with people with disabilities and ACASIs have not been used to investigate the relationship between disability, interpersonal violence (IPV), and physical and psychological health among people with developmental disabilities (PWDD). We developed an accessible ACASI specifically designed to allow PWDD to answer questions independently, while privately and securely collecting anonymous data related to their disability, IPV experiences, and physical and psychological health. We used a safety protocol to apply community based participatory research (CBPR) principles and an iterative process to create, test, and administer a cross-sectional ACASI survey to 350 adults with developmental disabilities in urban and rural locales. Most participants completed the ACASI independently and reported that its accessibility features allowed them to do so. Most also agreed that the ACASI was easy to use, its questions were easy to understand, and that they would prefer using an ACASI to answer IPV and health-related questions rather than in a face-to-face interview. The majority agreed that health and safety were critical issues to address. ACASI technology has the potential to maximize the independent and private participation of PWDD in research on sensitive topics. We recommend further exploration into accessibility options for ACASI technology, including hardware and Internet applications. Copyright © 2014 Elsevier Inc. All rights reserved.

Intimate partner violence (IPV) continue to have widespread negative effects on victims, children who witness IPV, and perpetrators. Current treatments have proven to be only marginally effective in stopping or reducing IPV by men. The two most prominent treatment approaches are feminist sociocultural and cognitive-behavioral therapy (CBT). The feminist sociocultural approach has been criticized for failing to adequately consider the therapeutic alliance, personality factors, and sole focus on patriarchy as the cause for IPV, whereas CBT has been criticized for failing to attend to motivation issues in treatment protocols. This article reviews the effectiveness of current treatments for partner-violent men, examines relationship and personality variables related to IPV and its treatment, and presents an emerging IPV treatment model that combines CBT and psychodynamic therapy. The article addresses how psychodynamic therapy is integrated into the more content-based elements of CBT. PsycINFO Database Record (c) 2012 APA, all rights reserved.
Changeable HA to improve MIPv6 protocol

For mobile IPv6, home agent (HA) plays an important role. Each mobile node (MN) has a home IP address, it will be not changeable. Also, the home agent (HA) of MN is not changeable. This rule provides the convenient for the ongoing communication without interruption. But it has some obvious drawbacks. Here, the new variable HA scheme is proposed. Every MN has a dynamic cache table, recording the information such as its home address, care-of address, and history address etc. If the accumulated time in one region exceeds that in the hometown, the foreign agent (FA) could become home agent (HA), the home agent could become history agent. Later, the performance of the new protocol is simulated with OPNET software, whose result shows the performance of the new protocol works better than that of the traditional protocol.

Intimate partner violence (IPV) is a pervasive public health problem, impacting the health and quality of life of survivors worldwide. The trauma of IPV is associated with a high incidence of mental illness, namely depressive and anxiety disorders, and posttraumatic stress disorder (PTSD). Moreover, literature endorses cognitive behavioral therapy (CBT) interventions as a gold standard for those with symptomatology consistent with anxiety disorders, mood disorders, and PTSD. However, efficacy has not been evaluated among a population of pregnant survivors of IPV. We present the protocol that will be used to explore the efficacy of trauma-informed cognitive behavioral therapy on maternal and child health outcomes for pregnant women with PTSD, depression, or anxiety symptomatology resulting from IPV. A secondary aim will be to test the validity and feasibility of study methodology to support the successful implementation of a full-scale randomized controlled trial. The Promoting Attachment Through Healing (PATH) study will use a mixed-methods approach grounded in an intersectional feminist framework to explore the effectiveness of trauma-informed CBT for pregnant survivors of IPV. Study participants will be recruited through the hospital-based Perinatal Mental Health Clinic (London, Ontario, Canada). A feasibility sample of 20 pregnant women (cohort 1) will be selected to engage in an eight-session antenatal CBT intervention facilitated by the program's perinatal clinical nurse specialist, with evaluation at baseline, at two months postpartum (intervention and online questionnaire), and at six and twelve months postpartum (online questionnaire only). Concurrently, we will conduct a retrospective audit of 100 medical charts (cohort 2; 50 charts of perinatal women who received CBT and 50 charts of women who did not receive perinatal CBT) from the past five years. The efficacy of the intervention will be based on a reduction of mental illness symptomatology, improved maternal-infant attachment, maternal coping, and maternal quality of life. Additionally, the feasibility of the protocol and acceptability of the intervention from the women's perspective will be examined. Inductive content analysis of all qualitative data will be used to determine common themes. Additionally, descriptive statistics, including measures of central tendency and dispersion, will be computed for all continuous variables. Alternatively, frequency tables will be constructed for all categorical variables. The work reported here is in the proposal phase. Once the protocol is implemented, we will report the results in a follow-up paper. Participant recruitment for cohort 1 has started and we have finished data collection for cohort 2. It is anticipated that the results will be available by the end of 2018. Findings will assess the acceptability of the study methodology and protocol for a full-scale randomized controlled trial. Furthermore, if CBT is proven effective for pregnant survivors of IPV, this intervention could be readily adopted by health care and social support services, thereby contributing to an improved standard of care for this unique population.

Efficient Mobility Management Signalling in Network Mobility Supported PMIPV6

Proxy Mobile IPV6 (PMIPV6) is a network based mobility management protocol which supports node's mobility without the contribution from the respective mobile node. PMIPV6 is initially designed to support individual node mobility and it should be enhanced to support mobile network movement. NEMO-BSP is an existing protocol to support network mobility (NEMO) in PMIPV6 network. Due to the underlying differences in basic protocols, NEMO-BSP cannot be directly applied to PMIPV6 network. Mobility management signaling and data structures used for individual node's mobility should be modified to support group nodes' mobility management efficiently. Though a lot of research work is in progress to implement mobile network movement in PMIPV6, it is not yet standardized and each suffers with different shortcomings. This research work proposes modifications in NEMO-BSP and PMIPV6 to achieve NEMO support in PMIPV6. It mainly concentrates on optimizing the number and size of mobility signaling exchanged while mobile network or mobile network node changes its access point. PMID:26366431

The study assessed the relationship between postpartum intimate partner violence (IPV) and postpartum health risks among young mothers over time. Data were collected from 2001 to 2005 on young women aged 14–25 attending obstetrics and gynecology clinics in two US cities. Postpartum IPV (i.e., emotional, physical, sexual) was assessed at 6 and 12 months after childbirth (n = 734). Four types of postpartum IPV patterns were examined: emerged IPV, dissipated IPV, repeated IPV, and no IPV. Emerged IPV occurred at 12 months postpartum, not 6 months postpartum. Dissipated IPV occurred at 6 months postpartum, not 12 months postpartum. Repeated IPV was reported at 6 months and 12 months postpartum. Postpartum health risks studied at both time points were perceived stress, depression, fear of condom negotiation, condom use, infant sleeping problems, and parental stress. Repeated measures analysis of covariance was used. The proportion of young mothers reporting IPV after childbirth increased from 17.9 % at 6 months postpartum to 25.3 % at 12 months postpartum (P < 0.001). Emerged and/or repeated postpartum IPV were associated with increased perceived stress, depression, fear of condom negotiation, and infant sleeping problems as well as decreased condom use (P < 0.05). Dissipated postpartum IPV was associated with decreased depression (P < 0.05). IPV screening and prevention programs for young mothers may reduce health risks observed in this group during the postpartum period. PMID:24562504
A Mechanism for Reliable Mobility Management for Internet of Things Using CoAP
Chun, Seung-Man; Park, Jong-Tae
2017-01-01
Under unreliable constrained wireless networks for Internet of Things (IoT) environments, the loss of the signaling message may frequently occur. Mobile Internet Protocol version 6 (MIPv6) and its variants do not consider this situation. Consequently, as a constrained device moves around different wireless networks, its Internet Protocol (IP) connectivity may be frequently disrupted and power can be drained rapidly. This can result in the loss of important sensing data or a large delay for time-critical IoT services such as healthcare monitoring and disaster management. This paper presents a reliable mobility management mechanism in Internet of Things environments with lossy low-power constrained device and network characteristics. The idea is to use the Internet Engineering Task Force (IETF) Constrained Application Protocol (CoAP) retransmission mechanism to achieve both reliability and simplicity for reliable IoT mobility management. Detailed architecture, algorithms, and message extensions for reliable mobility management are presented. Finally, performance is evaluated using both mathematical analysis and simulation.

Efficient Buffering Scheme in the LMA for Seamless Handover in PMIPv6
NASA Astrophysics Data System (ADS)
Kim, Kwang-Ryoul; Lee, Hyo-Beom; Choi, Hyon-Young; Min, Sung-Gi; Han, Youn-Hee
Proxy Mobile IPv6 (PMIPv6) is proposed as a new network-based local mobility protocol which does not involve the Mobile Node (MN) in mobility management. PMIPv6, which uses link-layer attachment information, reduces the movement detection time and eliminates duplicate address detection procedures in order to provide faster handover than Mobile IPv6 (MIPv6). To eliminate packet loss during the handover period, the Local Mobility Anchor (LMA) buffering scheme is proposed. In this scheme, the LMA buffers lost packets of the Mobile Access Gateway (MAG) and the MN during the handover and recovers them after handover. A new Automatic Repeat reQuest (ARQ) handler is defined which efficiently manages the LMA buffer. The ARQ handler relays ARQ result between the MAG and the MN to the LMA. The LMA removes any buffered packets which have been successfully delivered to the MN. The ARQ handler recovers the packet loss during the handover using buffered packets in the LMA. The ARQ information, between the MAG and LMA, is inserted in the outer header of IP-in-IP encapsulated packets of a standard PMIPv6 tunnel. Since the proposed scheme simply adds information to the standard operation of an IP-in-IP tunnel between the LMA and the MAG, it can be implemented seamlessly without modification to the original PMIPv6 messages and signaling sequence. Unlike other Fast Handovers for Mobile IPv6 (FMIPv6) based enhancement for PMIPv6, the proposed scheme does not require any handover related information before the actual handover.

The aim of this randomized controlled trial was to investigate the effect of an Internet-delivered cognitive behaviour therapy (iCBT), which incorporated emotion-regulation and conflict-resolution techniques, on intimate partner violence (IPV). Another aim was to test the theoretical underpinnings of the treatment model using mediation analysis. Sixty-five participants with aggression problems in intimate adult relationships were recruited from the community and were randomly assigned to iCBT or to a monitored waitlist control. Participants were assessed with standardized self-report measures of IPV or aggression (Multidimensional Measure of Emotional Abuse, Revised Conflict Tactics Scale, and Aggression Questionnaire), relationship quality (Dyadic Adjustment Scale), anxiety or depression symptomatology (Patient Health Questionnaire; Generalized Anxiety Disorder Screener), at pretreatment, posttreatment (8 weeks), and 1-year follow-up. Process variables (subscales of Dysfunctional and Emotional Regulation Scale and Anger Rumination Scale) were assessed weekly over the active treatment phase. Robust linear regression analysis of all randomized participants showed significant treatment effects on emotional abuse relative to control at postassessment. Mediation analysis using growth curve modeling revealed that the treatment effect was partially mediated by changes in emotion-regulation ability. Controlled effects on secondary outcomes were also observed. Analyses of uncontrolled effects indicted that gains on IPV were maintained at 1-year follow-up. iCBT focusing on enhancing conflict-resolution skills and emotion-regulation ability has the potential to reduce IPV among self-recruited individuals with mild forms of abusive behaviour in intimate relationships. Emotion-regulation ability is potentially a key therapeutic process of change. Internet-delivered clinician-guided cognitive behaviour therapy is a viable treatment option for reducing intimate partner violence among self-recruited individuals with mild forms of abusive behaviour. For persons who display patterns of frequent and severe violence, other treatments are most likely needed. Emotion-regulation training is potentially a key therapeutic component that ought to be incorporated in interventions targeting IPV. Copyright © 2017 John Wiley & Sons, Ltd.
Deployment of 464XLAT (RFC6877) alongside IPv6-only CPU resources at WLCG sites

IPv4 is now officially deprecated by the IETF. A significant amount of effort has already been expended by the HEPiX IPv6 Working Group on testing dual-stacked hosts and IPv6-only CPU resources. Dual-stack adds complexity and administrative overhead to sites that may already be starved of resource. This has resulted in a very slow uptake of IPv6 from WLCG sites. 464XLAT (RFC6877) is intended for IPv6 single-stack environments that require the ability to communicate with IPv4-only endpoints. This paper will present a deployment strategy for 464XLAT, operational experiences of using 464XLAT in production at a WLCG site and important information to consider prior to deploying 464XLAT.

Experience of intimate partner violence (IPV) can have adverse health impacts and has been associated with elevated rates of healthcare service utilization. Healthcare encounters present opportunities to identify IPV-related concerns and connect patients with services. The Veterans Health Administration (VHA) conducts IPV screening within an integrated healthcare system. The objectives of this study were to compare service utilization in the 6 months following IPV screening between those screening positive and negative for past-year IPV (IPV+, IPV-) and to examine the timing and types of healthcare services accessed among women screening IPV+. A retrospective chart review was conducted for 8888 female VHA patients across 13 VHA facilities who were screened for past-year IPV between April 2014 and April 2016. Demographic characteristics (age, race, ethnicity, marital status, veteran status), IPV screening response, and healthcare encounters (based on visit identification codes). In the 6 months following routine screening for past-year IPV, patients screening IPV+ were more likely to utilize outpatient care (aOR = 1.85 [CI 1.26, 2.70]), including primary care or psychosocial care, and to have an inpatient stay (aOR = 2.09 [CI 1.23, 3.57]), compared with patients screening IPV-. Among those with any utilization, frequency of outpatient encounters within the 6-month period following screening was higher among those screening IPV+ compared with those screening IPV-. The majority of patients screening positive for past-year IPV returned for an outpatient visit within a brief time frame following the screening visit (> 70% within 14 days, >95% within 6 months). More than one in four patients screening IPV+ had an emergency department visit within the 6 months following screening. Women who screen positive for past-year IPV have high rates of return to outpatient visits following screening, presenting opportunities for follow-up support. Higher rates of emergency department utilization and inpatient stays among women screening IPV+ may indicate adverse health outcomes related to IPV experience.

The tremendous demands from social market are pushing the booming development of mobile communications faster than ever before, leading to plenty of new advanced techniques emerging. With the converging of mobile and wireless communications with Internet services, the boundary between mobile personal telecommunications and wireless computer networks is disappearing. Wireless networks of the next generation need the support of all the advances on new architectures, standards, and protocols. Mobility management is an important issue in the area of mobile communications, which can be best solved at the network layer. One of the key features of the next generation wireless networks is all-IP infrastructure. This paper discusses the mobility management schemes for the next generation mobile networks through extending IP's functions with mobility support. A global hierarchical framework model for the mobility management of wireless networks is presented, in which the mobility management is divided into two complementary tasks: macro mobility and micro mobility. As the macro mobility solution, a basic principle of Mobile IP is introduced, together with the optimal schemes and the advances in IPv6. The disadvantages of the Mobile IP on solving the micro mobility problem are analyzed, on the basis of which three main proposals are discussed as the micro mobility solutions for mobile communications, including Hierarchical Mobile IP (HMIP), Cellular IP, and Handoff-Aware Wireless Access Internet Infrastructure (HAWAII). A unified model is also described in which the different micro mobility solutions can coexist simultaneously in mobile networks.

Additionally, the feasibility of the protocol and acceptability of the intervention from the women’s perspective will be examined. Inductive content analysis of all qualitative data will be used to determine common themes. Additionally, descriptive statistics, including measures of central tendency and dispersion, will be computed for all continuous variables. Alternatively, frequency tables will be constructed for all categorical variables. Results The work reported here is in the proposal phase. Once the protocol is implemented, we will report the results in a follow-up paper. Participant recruitment for cohort 1 has started and we have finished data collection for cohort 2. It is anticipated that the results will be available by the end of 2018. Conclusions Findings will assess the acceptability of the study methodology and protocol for a full-scale randomized controlled trial. Furthermore, if CBT is proven effective for pregnant survivors of IPV, this intervention could be readily adopted by health care and social support services, thereby contributing to an improved standard of care for this unique population.

Bivalent oral poliovirus vaccine (bOPV; types 1 and 3) is expected to replace trivalent OPV (tOPV) globally by April, 2016, preceded by the introduction of at least one dose of inactivated poliovirus vaccine (IPV) in routine immunisation programmes to eliminate vaccine-associated or vaccine-derived poliomyelitis from serotype 2 poliovirus. Because data are needed on sequential IPV-bOPV schedules, we assessed the immunogenicity of two different IPV-bOPV schedules compared with an all-IPV schedule in infants. We did a randomised, controlled, open-label, non-inferiority trial with healthy, full-term (>2·5 kg birthweight) infants aged 8 weeks (± 7 days) at six well-child clinics in Santiago, Chile. We used supplied lists to randomly assign infants (1:1:1) to receive three polio vaccinations (IPV by injection or bOPV as oral drops) at age 8, 16, and 24 weeks in one of three sequential schedules: IPV-bOPV-bOPV, IPV-IPV-bOPV, or IPV-IPV-IPV. We did the randomisation with blocks of 12 stratified by study site. All analyses were done in a masked manner. Co-primary outcomes were non-inferiority of the bOPV-containing schedules compared with the all-IPV schedule for seroconversion (within a 10% margin) and antibody titres (within two-thirds log2 titres) to poliovirus serotypes 1 and 3 at age 28 weeks, analysed in the per-protocol population. Secondary outcomes were seroconversion and titres to serotype 2 and faecal shedding for 4 weeks after a monovalent OPV type 2 challenge at age 28 weeks. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01841671, and is closed to new participants. Between April 25 and August 1, 2013, we assigned 570 infants to treatment: 190 to IPV-bOPV-bOPV, 192 to IPV-IPV-bOPV, and 188 to IPV-IPV-IPV. 564 (99%) were vaccinated and included in the intention-to-treat cohort, and 537 (94%) in the per-protocol analyses. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroconversion to type 1 poliovirus were 166 (98·8%) of 168, 95% CI 95·8-99·7; 178 (100%), 97·9-100·0; and 175 (100%), 97·9-100·0. Proportions with seroconvsion to type 3 poliovirus were 163 (98·2%) of 166, 94·8-99·4; 177 (100%), 97·9-100·0, and 172 (98·9%) of 174, 95·9-99·7. Non-inferiority was thus shown for the bOPV-containing schedules compared with the all-IPV schedule, with no significant differences between groups. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroprotective antibody titres to type 1 poliovirus were 168 (98·8%) of 170, 95% CI 95·8-99·7; 181 (100%), 97·9-100·0; and 177 (100%), 97·9-100·0. Proportions to type 3 poliovirus were 166 (98·2%) of 169, 94·9-99·4; 180 (100%), 97·9-100·0; and 174 (98·9%) of 176, 96·0-99·7. Non-inferiority comparisons could not be done for this outcome because median titres for the groups receiving OPV were greater than the assay's upper limit of detection (log2 titres >10·5). The proportions of children seroconverting to type 2 poliovirus in the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, were 130 (77·4%) of 168, 95% CI 70·5-83·0; 169 (96·0%) of 176, 92·0-98·0; and 175 (100%), 97·8-100. IPV-bOPV schedules resulted in almost a 0·3 log reduction of type 2 faecal shedding compared with the IPV-only schedule. No participants died during the trial; 81 serious adverse events were reported, of which one was thought to be possibly vaccine-related (intestinal intussusception). Seroconversion rates against polioviruses types 1 and 3 were non-inferior in sequential schedules containing IPV and bOPV, compared with an all-IPV schedule, and proportions of infants with protective antibodies were high after all three schedules. One or two doses of bOPV after IPV boosted intestinal immunity for poliovirus type 2, suggesting possible cross protection. Additionally, there was evidence of humoral priming for type 2 from one dose of IPV. Our findings could give policy makers flexibility when choosing a vaccination schedule, especially when trying to eliminate vaccine-associated and vaccine-derived poliomyelitis.

Intimate partner violence (IPV) can be considered a leading public health problem affecting approximately 50% of women during the course of their lifetimes. This study was carried out with the aim of re-testing the prevalence data and providing sufficient grounds for decision-makers in family medicine in Slovenia to adopt much-needed protocols for IPV management in the field. In January 2012, every tenth general practitioner (GP) registered in Slovenia, of a total of 958, was invited to participate in a multi-centre cross-sectional study, and 9.4% of them, working in 90 family practices, agreed to participate. From February 1 to March 1, 2012, they asked every fifth family practice attendee aged 18 years and above, regardless of gender, to participate in the study. The short version of Domestic Violence Exposure Questionnaire was administered to 2572 patients. In the sample, there were more women (62.9% (n = 1617)). The average age of all the participants was 49.0 ± 16.1 years. Of 2572 participants (95.3% response rate), 17.1% people had been exposed to either emotional or both physical and emotional abuse. The prevalence of psychological violence was 10.3%, and that of concurrent physical and psychological abuse 6.8%, with all the patients exposed to physical IPV disclosing concurrent psychological violence. Female gender and previous formal divorce were risk factors identified in all three multivariate logistic regression models. The odds of concurrent physical and psychological and either type of IPV exposure in patients were lessened by an age of 65 years or above. The odds for either type of IPV were also lower in single people, while in concurrent physical and psychological IPV exposure, living in urban settings acted as a protective factor. In Slovenian family practice attendees, an IPV exposure prevalence of approximately 17% should be considered a valid estimation.
Is gender important? Victimisation and perpetration of intimate partner violence in mainland China.

Establishing the prevalence of intimate partner violence (IPV) has been recommended by International Conventions and Declarations for some time beginning with the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW Articles 12 and 19) in 1979. One important recommendation of such international protocols is the implementation of national population prevalence surveys to establishing IPV as a serious social issue globally, which is intended to provide data for planning effective responses within signatory countries. However, not all countries have undertaken national prevalence surveys meaning that there are gaps in our understanding of who are the perpetrators and victims of IPV in different cultural contexts. This article presents the results of a scoping review of literature examining gender differences in prevalence rates of victimisation and perpetration of IPV in mainland China (hereon China). There has been little written about the prevalence of IPV in China generally, and this scoping process located only nine peer-reviewed articles written in both English- and Chinese-language journals focusing on both gender and IPV published between 1997 and 2016. Results of this scoping review demonstrate that while both women and men perpetrate IPV in China, the prevalence rates of different types of IPV reflect gender differences in both perpetration and victimisation, suggesting that IPV is not a unitary phenomenon. The paper concludes by discussing the implications of the findings including the importance of increasing awareness of IPV in China more generally and developing gender-specific interventions to directly address different types of IPV. Directions for future research are also canvassed. © 2018 John Wiley & Sons Ltd.
Forwarding techniques for IP fragmented packets in a real 6LoWPAN network.

Wireless Sensor Networks (WSNs) are attracting more and more interest since they offer a low-cost solution to the problem of providing a means to deploy large sensor networks in a number of application domains. We believe that a crucial aspect to facilitate WSN diffusion is to make them interoperable with external IP networks. This can be achieved by using the 6LoWPAN protocol stack. 6LoWPAN enables the transmission of IPv6 packets over WSNs based on the IEEE 802.15.4 standard. IPv6 packet size is considerably larger than that of IEEE 802.15.4 data frame. To overcome this problem, 6LoWPAN introduces an adaptation layer between the network and data link layers, allowing IPv6 packets to be adapted to the lower layer constraints. This adaptation layer provides fragmentation and header compression of IP packets. Furthermore, it also can be involved in routing decisions. Depending on which layer is responsible for routing decisions, 6LoWPAN divides routing in two categories: mesh under if the layer concerned is the adaptation layer and route over if it is the network layer. In this paper we analyze different routing solutions (route over, mesh under and enhanced route over) focusing on how they forward fragments. We evaluate their performance in terms of latency and energy consumption when transmitting IP fragmented packets. All the tests have been performed in a real 6LoWPAN implementation. After consideration of the main problems in forwarding of mesh frames in WSN, we propose and analyze a new alternative scheme based on mesh under, which we call controlled mesh under.

Intimate partner violence (IPV) is a critical public health and human rights concern globally, including for refugee women in low-resource settings. Little is known about effective interventions for this population. IPV and psychological distress have a bi-directional relationship, indicating the potential benefit of a structured psychological component as part of efforts to reduce IPV for women currently in violent relationships. This protocol describes a cluster randomized controlled trial aimed at evaluating an 8-session integrated psychological and advocacy intervention (Nguvu) with female adult survivors of past-year IPV displaying moderate to severe psychological distress. Outcomes are reductions in: recurrence of IPV; symptoms of anxiety, depression and post-traumatic stress (primary); and functional impairment (secondary). Hypothesized mediators of the intervention are improvements in social support, coping skills and support seeking. We will recruit 400 participants from existing women's support groups operating within villages in Nyarugusu refugee camp, Tanzania. Women's groups will be randomized to receive the intervention (Nguvu and usual care) or usual care alone. All eligible women will complete a baseline assessment (week 0) followed by a post-treatment (week 9) and a 3-month post-treatment assessment (week 20). The efficacy of the intervention will be determined by between-group differences in the longitudinal trajectories of primary outcomes evaluated using mixed-effects models. Study procedures have been approved by Institutional Review Boards in the United States and Tanzania. This trial will provide evidence on the efficacy of a novel integrated group intervention aimed at secondary prevention of IPV that includes a structured psychological component to address psychological distress. The psychological and advocacy components of the proposed intervention have been shown to be efficacious for their respective outcomes when delivered in isolation; however, administering these approaches through a single, integrated intervention may result in synergistic effects given the interrelated, bidirectional relationship between IPV and mental health. Furthermore, this trial will provide information regarding the feasibility of implementing a structured intervention for IPV and mental health in a protracted humanitarian setting.

The prevalence of intimate partner violence (IPV), a gross violation of human rights, ranges widely across the world with higher prevalence reported in low- and middle-income countries. Evidence related mainly to physical health shows that IPV has both direct and indirect impacts on women's health. Little is known about the impact of IPV on the mental health of women, particularly after childbirth. To describe the prevalence of IPV experienced by women 6-8 months after childbirth in rural Bangladesh and the factors associated with physical IPV. The study also aims to investigate the association between IPV and maternal depressive symptoms after childbirth. The study used cross-sectional data at 6-8 months postpartum. The sample included 660 mothers of newborn children. IPV was assessed by physical, emotional, and sexual violence. The Edinburgh Postnatal Depression Scale assessed maternal depressive symptoms. Prevalence of physical IPV was 52%, sexual 65%, and emotional 84%. The husband's education (OR: 0.41, CI: 0.23-0.73), a poor relationship with the husband (OR: 2.64, CI: 1.07-6.54), and emotional violence by spouse (OR: 1.58, CI: 1.35-1.83) were significantly associated with physical IPV experienced by women. The perception of a fussy and difficult child (OR: 1.05, CI: 1.02-1.08), a poor relationship with the husband (OR: 4.95, CI: 2.55-9.62), and the experience of physical IPV (OR: 2.83, CI: 1.72-4.64) were found to be significant predictors of maternal depressive symptoms among women 6-8 months after childbirth. Neither forced sex nor emotional violence by an intimate partner was found to be significantly associated with maternal depressive symptoms 6-8 months postpartum. It is important to screen for both IPV and depressive symptoms during pregnancy and postpartum. Since IPV and spousal relationships are the most important predictors of maternal depressive symptoms in this study, couple-focused interventions at the community level are suggested.

The objective of this study was to examine the stability of physical and sexual intimate partner violence (IPV) perpetration from adolescence to emerging adulthood among sexual minorities. Adolescents who identified as a sexual minority (N = 135; 71.1% female; mean age = 15.02, standard deviation=.77; 34.1% African-American/black, 26.7% white, 22.2% Hispanic) from southeast Texas were assessed annually for 6 years on their IPV perpetration. Structural equation modeling demonstrated that physical IPV perpetration was modestly stable across years 1-4 (24.6%, 24.6%, 26.4%, and 21.6%, respectively), decreased in year 5 (18.6%), and increased in year 6 (24.5%). The stability of sexual IPV perpetration was high across all 6 years (14.3%, 13%, 14.9%, 10.8%, 12.4%, and 14.4%). This is the first study to examine the stability of IPV perpetration among sexual minority adolescents. Findings suggest that the development of interventions for IPV among sexual minority adolescents is needed, as IPV is unlikely to desist from adolescence to emerging adulthood.

The purpose of this study was to conduct a baseline assessment of intimate partner violence (IPV) practices in a pediatric hospital system. The Delphi Instrument for Hospital-based Domestic Violence Programs was used to assess the structure and components of the hospital system's IPV practices. Through key stakeholder interviews, we also assessed IPV practices in individual patient care areas. Qualitative analysis of interview data used a grounded theory approach. The hospital scored 17 of 100 points on the Delphi instrument assessment. Key areas of weakness identified by the Delphi instrument and interviews included lack of coordinated provider training and evaluation of IPV-related processes and no standards for IPV screening, safety assessment, and documentation. Most interviewees supported addressing IPV; all identified barriers to IPV screening at individual provider and institutional levels. Institutional barriers included lack of a standardized response to IPV disclosure, need for individualized screening protocols for different patient care settings, lack of standardized provider training, concerns about overextending social work resources, and lack of resources for hospital staff experiencing vicarious trauma. Individual barriers included concern that screening may harm physician-patient-family relationships and the perception that physicians are unwilling to address psychosocial issues. The Delphi Instrument for Hospital-based Domestic Violence Programs identified weaknesses and key areas for improvement in IPV practices. Deficiencies revealed by the Delphi instrument were affirmed by individual interview results. Institutional and individual provider level barriers must be addressed to optimize IPV practices in a pediatric hospital system. Copyright © 2015 by the American Academy of Pediatrics.

Women who experience intimate partner violence (IPV) often do not perceive themselves as abused. This study sought to estimate the health effects of unperceived IPV (uIPV), taking violence-free women as the reference, and to compare the effects of uIPV with those of perceived IPV (pIPV). We performed a cross-sectional population study through telephone interviews of 2835 women aged 18 to 70 years living in the region of Madrid and having an ongoing intimate partner relationship or contact with a former partner in the preceding year. Based on 26 questions from the Conflict Tactics Scale-1 and the Enquête Nacional sur les Violences envers les Femmes en France and the question "Do you feel abused by your partner?" a variable was constructed in three categories, namely, the absence of IPV, uIPV and pIPV. Using logistic regression, we analyzed the association between health problems, medication use, health-service utilization and IPV (perceived and unperceived) vis-à-vis the absence of IPV. There were 247 cases of uIPV and 96 of pIPV (prevalences of 8.8% and 3.4%, respectively). The multivariate analysis showed that a substantial number of the outcomes explored were associated with uIPV, pIPV, or both. The highest odds ratios (ORs) were obtained for depression (Patient Health Questionnaire-9≥10) (uIPV: OR 3.4, 95% CI 2.4-3.8; and pIPV: 4.1, 95%CI 2.5-6.8). In most problems, the ORs did not significantly differ between the two types of IPV. uIPV is 2.6 times more frequent than pIPV and is associated with at least as many health problems as pIPV.

Women with activity limitations (ALs) are at risk for Intimate partner violence (IPV). This study examined IPV in men versus women with ALs. Data from the Canadian 1999 General Social Survey compared physical, sexual, emotional, and financial IPV from a current/expartner in 5 years for men and women with ALs compared with those without ALs. Logistic regression examined sex differences in IPV among those with ALs, adjusting for sociodemographic factors. Rates of physical (11.9% versus 7.8%; p < 0.0001), sexual (3.5% versus 1.4%; p < 0.0001), emotional (27.1% versus 17.7%; p < 0.0001), and financial (7.5% versus 3.4%; p < 0.0001) IPV were greater in women with compared with without ALs. A similar pattern was seen for men, with greater rates of physical (9.2% versus 6.6%; p = 0.006), emotional (22.6% versus 18.2%; p = 0.002), and financial (2.6% versus 1.4%; p = 0.005) IPV in men with ALs than men without ALs. Risk factors for IPV included younger age, being divorced/separated or single, and having lower income and poorer health. Women with ALs were more likely than men to experience any IPV (29.1% versus 24.9%) and more severe and more incidents of IPV. In multivariable analysis, women were no longer at greater risk for "any IPV" after adjusting for sociodemographic variables (odds ratio = 1.09; 95% confidence interval, 0.88-1.36). This is the first study to document IPV rates in men with ALs. Women with ALs were more likely to be divorced/separated, living in poverty, and in poorer health than men with ALs. These factors accounted for sex differences in IPV rates.

Luckily, new communication technologies and protocols are nowadays designed considering security issues. A clear example of this can be found in the Internet of Things (IoT) field, a quite recent area where communication technologies such as ZigBee or IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) already include security features to guarantee authentication, confidentiality and integrity. More recent technologies are Low-Power Wide-Area Networks (LP-WAN), which also consider security, but present initial approaches that can be further improved. An example of this can be found in Long Range (LoRa) and its layer-two supporter LoRa Wide Area Network (LoRaWAN), which include a security scheme based on pre-shared cryptographic material lacking flexibility when a key update is necessary. Because of this, in this work, we evaluate the security vulnerabilities of LoRaWAN in the area of key management and propose different alternative schemes. Concretely, the application of an approach based on the recently specified Ephemeral Diffie⁻Hellman Over COSE (EDHOC) is found as a convenient solution, given its flexibility in the update of session keys, its low computational cost and the limited message exchanges needed. A comparative conceptual analysis considering the overhead of different security schemes for LoRaWAN is carried out in order to evaluate their benefits in the challenging area of LP-WAN.

There is a demand of affordable IPV in the World. Statens Serum Institut (SSI) has developed three reduced dose IPV formulations adsorbed to aluminium hydroxide; 1/3 IPV-Al, 1/5 IPV-Al and 1/10 IPV-Al SSI, and now report the results of the first investigations in humans. 240 Danish adolescents, aged 10-15years, and childhood vaccinated with IPV were booster vaccinated with 1/3 IPV-Al, 1/5 IPV-Al, 1/10 IPV-Al or IPV Vaccine SSI. The booster effects (GMTRs) of the three IPV-Al SSI were compared to IPV Vaccine SSI, and evaluated for non-inferiority. The pre-vaccination GMTs were similar across the groups; 926 (type 1), 969 (type 2) and 846 (type 3) in the total trial population. The GMTRs by poliovirus type and IPV formulation were: Type 1: 17.0 (1/3 IPV-Al), 13.0 (1/5 IPV-Al), 7.1 (1/10 IPV-Al) and 42.2 (IPV Vaccine SSI). Type 2: 12.5 (1/3 IPV-Al), 13.1 (1/5 IPV-Al), 7.6 (1/10 IPV-Al) and 47.8 (IPV Vaccine SSI). Type 3: 14.5 (1/3 IPV-Al), 16.2 (1/5 IPV-Al), 8.9 (1/10 IPV-Al) and 62.4 (IPV Vaccine SSI) Thus, the three IPV-Al formulations were highly immunogenic, but inferior to IPV Vaccine SSI, in this booster vaccination trial. No SAE and no AE of severe intensity occurred. 59.2% of the subjects reported at least one AE. Injection site pain was the most frequent AE in all groups; from 24.6% to 43.3%. Injection site redness and swelling frequencies were<5% in most and<10% in all groups. The most frequent systemic AEs were fatigue (from 8.2% to 15.0%) and headache (from 15.0% to 28.3%). Most AEs were of mild intensity. In conclusion, the three IPV-Al SSI were safe in adolescents and the booster effects were satisfactory. ClinicalTrials.gov registration number: NCT02280447.

The shortage of IP addresses and the scalability of routing systems [1] are challenges for the Internet. The idea of dividing existing IP addresses between identities and locations is one of the important research directions. This paper proposed a new decimal network architecture based on IPv9 [11], and decimal network IP address from E.164 principle of traditional telecommunication network, the IP address level, which helps to achieve separation and identification and location of IP address, IP address form a multilayer network structure, routing scalability problem in remission at the same time, to solve the problem of IPv4 address depletion. On the basis of IPv9, a new decimal network architecture is proposed, and the IP address of the decimal network draws on the E.164 principle of the traditional telecommunication network, and the IP addresses are hierarchically divided, which helps to realize the identification and location separation of IP addresses, the formation of multi-layer IP address network structure, while easing the scalability of the routing system to find a way out of IPv4 address exhausted. In addition to modifying DNS [10] simply and adding the function of digital domain, a DDNS [12] is formed. At the same time, a gateway device is added, that is, IPV9 gateway. The original backbone network and user network are unchanged.

Previous research suggests that intimate partner violence (IPV), particularly physical or sexual violence, was associated with cervical cancer. However, there is less work examining the mechanism of the relationship between IPV and cervical cancer. The purpose of this cross-sectional study was to examine psychosocial factors (e.g., stress, social support, self-esteem, and depressive symptoms) as mediators of the relationship between IPV and cervical cancer among 532 Thai women with gynecological problems. About 21.1% of participants reported any type of IPV (e.g., physical, sexual, or emotional violence) in the past year and 22.2% had cervical cancer. IPV was significantly positively associated with stress, depressive symptoms, and cervical cancer but negatively correlated with social support and self-esteem. Results from structural equation modeling indicated that not only did IPV exhibit significantly direct effects on social support, stress, and depressive symptoms, and indirect effects on self-esteem, but it also had a significant, positive, total effect on cervical cancer. IPV exhibited the significant indirect effect on cervical cancer through social support, self-esteem, stress, and depressive symptoms. The model fitted very well to the empirical data and explained 9% of variance. The findings affirmed that those psychosocial factors were mediators of the relationship between IPV and cervical cancer. Health care protocols for abused women should include screening for and treatment of IPV-related psychosocial factors. Interventions that provide social support and protect self-esteem should reduce stress and depressive symptoms among abused women, thereby reducing the risk of cervical cancer. © The Author(s) 2014.

Safety and immunogenicity of 2 investigational formulations of diphtheria, tetanus and Haemophilus influenzae type b antigens of the combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliomyelitis-Hib vaccine (DTPa-HBV-IPV/Hib) were evaluated in a Primary (NCT01248884) and a Booster vaccination (NCT01453998) study. In the Primary study, 721 healthy infants (randomized 1:1:1) received 3 doses of DTPa-HBV-IPV/Hib formulation A (D A T A Pa-HBV-IPV/Hib), or B (D B T B Pa-HBV-IPV/Hib) or the licensed DTPa-HBV-IPV/Hib vaccine (Infanrix hexa, GSK; control group) at 2, 3, 4 months of age. Infants were planned to receive a booster dose at 12-15 months of age with the same formulation received in the Primary study; however, following high incidence of fever associated with the investigational formulations in the Primary study, the Booster study protocol was amended and all infants yet to receive a booster dose (N = 385) received the licensed vaccine. In the Primary study, non-inferiority of 3-dose vaccination with investigational formulations compared with the licensed vaccine was not demonstrated due to anti-pertactin failing to meet the non-inferiority criterion. Post-primary vaccination, most infants had seroprotective levels of anti-diphtheria (100% of infants), anti-tetanus antigens (100%), against hepatitis B (≥ 97.5% across groups), polyribosyl-ribitol-phosphate (≥ 88.0%) and poliovirus types 1-3 (≥ 90.5%). Seropositivity rates for each pertussis antigen were 100% in all groups. Higher incidence of fever (> 38°C) was reported in infants receiving the investigational formulations (Primary study: 75.0% [A] and 72.1% [B] vs 58.8% [control]; Booster study, before amendment: 49.4% and 46.6% vs 37.4%, respectively). The development of the investigational formulations was not further pursued.

ABSTRACT Safety and immunogenicity of 2 investigational formulations of diphtheria, tetanus and Haemophilus influenzae type b antigens of the combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliomyelitis-Hib vaccine (DTPa-HBV-IPV/Hib) were evaluated in a Primary (NCT01248884) and a Booster vaccination (NCT01453998) study. In the Primary study, 721 healthy infants (randomized 1:1:1) received 3 doses of DTPa-HBV-IPV/Hib formulation A (DATAPa-HBV-IPV/Hib), or B (DBTBPa-HBV-IPV/Hib) or the licensed DTPa-HBV-IPV/Hib vaccine (Infanrix hexa, GSK; control group) at 2, 3, 4 months of age.

Intimate partner violence (IPV) during the first year postpartum is common in Bangladesh, and many infants are exposed to hostile and aggressive environment. The aim of the current study was to investigate how IPV (physical, emotional, and sexual) impacts on the mother's perception of her infant's temperament 6 to 8 months postpartum, and whether maternal depressive symptom at 6 to 8 months postpartum is a mediator in this association. A total of 656 rural Bangladeshi women and their children 6 to 8 months postpartum were included in this study. Data were collected by structured interviews. The women were asked about physical, sexual, and emotional IPV; depressive symptoms (Edinburgh Postnatal Depressive Symptoms [EPDS]); and their perception of infant temperament assessed by the Infant Characteristic Questionnaire (ICQ). Descriptive analyses were conducted for prevalence of IPV and maternal depressive symptoms. Mediation analysis was conducted with a series of linear regressions with types of IPV as independent variables, ICQ including its subscales as dependent variables and maternal depressive symptoms as potential mediator. All the analyses were adjusted for the woman's and her husband's ages and number of children of the couple. Nearly 90% of the mothers reported some kind of IPV at 6 to 8 months postpartum. All types of IPV were directly associated with the mother's perception of her infant as unadaptable. Maternal depressive symptom was a mediating factor between physical IPV and the ICQ subscales fussy-difficult and unpredictable. In addition, depressive symptoms mediated between sexual and emotional IPV, and the mother's perception of the infant as unpredictable. The results showed that IPV influenced how mothers perceived their infant's temperament. It is important that health care professionals at maternal and child health services enquire about IPV with possibilities to refer the family or the mother and infant for appropriate support.

We investigated the odds of intimate partner violence (IPV) among primary care patients across subgroups of transgender and gender nonconforming (TGNC) individuals relative to cisgender women, and cisgender sexual minority men and women relative to cisgender heterosexual men and women. Participants completed an IPV screener as part of routine primary care visits at an urban community health center (N = 7572). Electronic medical record data were pooled for all patients who received the IPV screener January 1 to December 31, 2014. Overall, 3.6% of the sample reported experiencing physical or sexual IPV in the past year. Compared to cisgender women (past-year prevalence 2.7%), all TGNC subgroups reported elevated odds of physical or sexual IPV, including transgender women (past-year prevalence 12.1%; adjusted odds ratio [AOR] = 5.0, 95% confidence interval [CI] = 2.9-8.6), transgender men (6.6%; AOR = 2.4, 95% CI: 1.2-4.6), gender non-binary individuals (8.2%, AOR = 3.1, 95% CI = 1.7-5.4), and TGNC individuals who did not report their gender identity (9.1%; AOR = 3.7, 95% CI = 2.2-6.3). The prevalence of isolation-related IPV and controlling behaviors was also high in some TGNC groups. Our findings support that IPV is prevalent across genders and sexual orientations. Clinical guidelines for IPV screening should be expanded to include TGNC individuals and not just cisgender women. Future research could explore the complex patterns by which individuals of different genders are at increased risk for different types of IPV, and investigate the best ways to screen TGNC patients and support TGNC survivors.

Objectives Intimate partner violence (IPV) is an important contributor to the burden of disease in South Africa. Evidence-based approaches to IPV in primary care are lacking. This study evaluated a project that implemented a South African protocol for screening and managing IPV. This article reports primarily on the benefits of this intervention from the perspective of women IPV survivors. Design This was a project evaluation involving two urban and three rural primary care facilities. Over 4–8 weeks primary care providers screened adult women for a history of IPV within the previous 24 months and offered referral to the study nurse. The study nurse assessed and managed the women according to the protocol. Researchers interviewed the participants 1 month later to ascertain adherence to their care plan and their views on the intervention. Results In total, 168 women were assisted and 124 (73.8%) returned for follow-up. Emotional (139, 82.7%), physical (115, 68.5%), sexual (72, 42.9%) and financial abuse (72, 42.9%) was common and 114 (67.9%) were at high/severe risk of harm. Adherence to the management plan ranged from testing for syphilis 10/25 (40.0%) to consulting a psychiatric nurse 28/58 (48.3%) to obtaining a protection order 28/28 (100.0%). Over 75% perceived all aspects of their care as helpful, except for legal advice from a non-profit organisation. Women reported significant benefits to their mental health, reduced alcohol abuse, improved relationships, increased self-efficacy and reduced abusive behaviour. Two characteristics seemed particularly important: the style of interaction with the nurse and the comprehensive nature of the assessment. Conclusion Female IPV survivors in primary care experience benefit from an empathic, comprehensive approach to assessing and assisting with the clinical, mental, social and legal aspects. Primary care managers should find ways to integrate this into primary care services and evaluate it further. PMID:22146888

The Thread protocol is a recent development based on 6LoWPAN (IPv6 over IEEE 802.15.4), but with extensions regarding a more media independent approach, which - additionally - also promises true interoperability. To evaluate and analyse the operation of a Thread network a given open source 6LoWPAN stack for embedded devices (emb::6) has been extended in order to comply with the Thread specification. The implementation covers Mesh Link Establishment (MLE) and network layer functionality as well as 6LoWPAN mesh under routing mechanism based on MAC short addresses. The development has been verified on a virtualization platform and allows dynamical establishment of network topologies based on Thread’s partitioning algorithm.

Intimate partner violence (IPV) is a common form of violence experienced by pregnant women and is believed to have adverse mental health effects postnatally. This study investigated the association of postnatal depression (PND) and suicidal ideation with emotional, physical and sexual IPV experienced by women during pregnancy. Data were collected from 842 women interviewed postnatally in six postnatal clinics in Harare, Zimbabwe. We used the World Health Organization versions of IPV and Centre for Epidemiological Studies - Depression Scale measures to assess IPV and PND respectively. We derived a violence severity variable and combined forms of IPV variables from IPV questions. Logistic regression was used to analyse data whilst controlling for past mental health and IPV experiences. One in five women [21.4% (95% CI 18.6-24.2)] met the diagnostic criteria for PND symptomatology whilst 21.6% (95% CI 18.8-24.4) reported postpartum suicide thoughts and 4% (95% CI 2.7-5.4) reported suicide attempts. Two thirds (65.4%) reported any form of IPV. Although individual forms of severe IPV were associated with PND, stronger associations were found between PND and severe emotional IPV or severe combined forms of IPV. Suicidal ideation was associated with emotional IPV. Other forms of IPV, except when combined with emotional IPV, were not individually associated with suicidal ideation. Emotional IPV during pregnancy negatively affects women's mental health in the postnatal period. Clinicians and researchers should include it in their conceptualisation of violence and health. Further research must look at possible indirect relationships between sexual and physical IPV on mental health. Copyright © 2016 Elsevier Inc. All rights reserved.

To describe the prevalence of intimate partner violence (IPV) in Spain in the last year and at some point during the lifetime, to determine health status in women according to whether they had experienced IPV or not, and to analyze the individual variables associated with IPV in Spain. A cross-sectional study was performed of the database, Macrosurvey on Gender Violence in Spain 2011. This database includes data on 7,898 women older than 18 years old. The dependent variables were IPV-last year, IPV-ever in life. Covariates consisted of sociodemographic characteristics, socioeconomic status, maternal experience of IPV, social support, and self-care. The measure of association used was the OR with its 95% confidence interval (95% CI). A total of 3.6% of women had experienced IPV-last year and 12.2% ever in life. Female victims of IPV had poorer health than women who had not experienced IPV. Immigrant women living in Spain for 6 years or more were more likely to experience IPV-ever in life than Spanish women [OR (95% CI): 1.95 (1.50, 2.53)]. An interaction was found between nationality and the existence of children under 18 years old. Among women with children under 18 years old, immigrant women were more likely to experience IPV-last year than Spanish women [OR (95% CI): 1.99 (1.25, 3.17)]. Other variables associated with IPV were age, low socioeconomic status, low social support and having a mother who had experienced IPV. In Spain, some women have a higher probability of experiencing IPV. The variables associated with greater vulnerability to IPV should be taken into account when implementing measures to prevent or alleviate IPV. Copyright © 2013 SESPAS. Published by Elsevier Espana.

Intimate partner violence (IPV) against women is a global public health concern. While community-level gender norms and attitudes to IPV are recognised drivers of IPV risk, there is little evidence on how interventions might tackle these drivers to prevent IPV at the community-level. This secondary analysis of data from the SASA! study explores the pathways through which SASA!, a community mobilisation intervention to prevent violence against women, achieved community-wide reductions in physical IPV. From 2007 to 2012 a cluster randomised controlled trial (CRT) was conducted in eight communities in Kampala, Uganda. Cross-sectional surveys of a random sample of community members, aged 18-49, were undertaken at baseline (n = 1583) and 4 years post intervention implementation (n = 2532). We used cluster-level intention to treat analysis to estimate SASA!'s community-level impact on women's past year experience of physical IPV and men's past year perpetration of IPV. The mediating roles of community-, relationship- and individual-level factors in intervention effect on past year physical IPV experience (women)/perpetration (men) were explored using modified Poisson regression models. SASA! was associated with reductions in women's past year experience of physical IPV (0.48, 95 % CI 0.16-1.39), as well as men's perpetration of IPV (0.39, 95 % CI 0.20-0.73). Community-level normative attitudes were the most important mediators of intervention impact on physical IPV risk, with norms around the acceptability of IPV explaining 70 % of the intervention effect on women's experience of IPV and 95 % of the effect on men's perpetration. The strongest relationship-level mediators were men's reduced suspicion of partner infidelity (explaining 22 % of effect on men's perpetration), and improved communication around sex (explaining 16 % of effect on women's experience). Reduced acceptability of IPV among men was the most important individual-level mediator (explaining 42 % of effect on men's perpetration). These results highlight the important role of community-level norm-change in achieving community-wide reductions in IPV risk. They lend strong support for the more widespread adoption of community-level approaches to preventing violence. ClinicalTrials.gov, NCT00790959 . Registered 13th November 2008.

The immunogenicity of a primary series of a new, fully liquid DTaP-IPV-Hep B-PRP-T vaccine (Hexaxim), administered at 2, 4, 6 months of age in four clinical studies is reviewed. Immunogenicity data at 1 month after the third vaccination were assessed and pooled from a total of 1270 participants (per-protocol population) in four randomized clinical trials in Argentina, Mexico, and Peru. Hepatitis B vaccine was not administered at birth. All seroprotection (D, T, polio-1, -2, -3, Hep B, PRP-T [Hib]), seroconversion (PT and FHA), and vaccine response (PT and FHA) data were high, and were similar to licensed comparators (pooled SP, SC, and VR rates were 97.1-100%, 96.0-97.0%, and 99.7-99.9%, respectively). These data show the good immunogenicity of this new hexavalent vaccine that can provide the opportunity to increase global compliance to complex pediatric vaccination schedules. Copyright © 2013.

To compare intimate partner violence (IPV) prevalence rates in 2006 and 2012 in a nationally representative household sample in Brazil. The associations between IPV and substance use were also investigated. IPV was assessed using the Conflict Tactic Scale-R in two waves (2006/2012) of the Brazilian Alcohol and Drugs Survey. Weighted prevalence rates and adjusted logistic regression models were calculated. Prevalence rates of IPV victimization decreased significantly, especially among women (8.8 to 6.3%). The rates of IPV perpetration also decreased significantly (10.6 to 8.4% for the overall sample and 9.2 to 6.1% in men), as well as the rates of bidirectional violence (by individuals who were simultaneously victims and perpetrators of violence) (3.2 to 2.4% for the overall sample). Alcohol increased the likelihood of being a victim (odds ratio [OR] = 1.6) and perpetrator (OR = 2.4) of IPV. Use of illicit drugs increased up to 4.5 times the likelihood of being a perpetrator. In spite of the significant reduction in most types of IPV between 2006 and 2012, violence perpetrated by women was not significantly reduced, and the current national rates are still high. Further, this study suggests that use of alcohol and other psychoactive drugs plays a major role in IPV. Prevention initiatives must take drug misuse into consideration.

Supportive care for survivors of intimate partner violence (IPV) remains limited in primary care settings. Low-income and Spanish-speaking survivors of IPV are even more disadvantaged, given the dearth of linguistically and culturally appropriate interventions for IPV. We conducted semi-structured individual interviews with 17 healthcare workers, including physicians, nurses, and social workers, to describe how healthcare workers serving primarily low-income, Latina populations are currently screening and responding to IPV disclosure, and to explore the acceptability of integrating an interactive, personalized safety decision aid application-myPlan app-into the clinic setting. Despite recognition of IPV as a problem, none of the clinical sites had a protocol to guide screening and response to IPV disclosure. Screening practices varied across the sites, sometimes conducted by medical assistants prior to the provider visit and other times by the physician or nurse provider. When IPV was disclosed, it was often during assessment for a presenting problem such as poor sleep or anxiety. Most healthcare workers felt that clinical and community resources were limited for their patients experiencing IPV. The "warm hand-off" to a social worker was the most common response strategy when possible; otherwise, women were given information about available resources such as hotlines and safe houses. We discuss structural, family, and individual barriers to accessing safety resources for underserved women and review how an easily accessible safety decision app, such as myPlan, could be a resource for women to safely tailor an action plan for her situation. © 2018 Wiley Periodicals, Inc.

Intimate partner violence (IPV) is a public health concern, affecting one-third of US women. Prior research suggests an association between exposure to IPV and poor maternal perinatal health, but the underlying biological correlates are not well understood. This study examined the relationship between exposure to IPV and proinflammatory cytokine levels, a candidate mechanism accounting for poor psychiatric and obstetric outcomes, across the perinatal period. Data were obtained from a prospective, longitudinal cohort study of 171 women receiving obstetrical care from a hospital-based practice serving a predominantly low-income minority population. Participants completed questionnaires on IPV exposure, psychiatric symptoms, and psychosocial and obstetric factors and provided blood samples at 18 and 32 weeks of gestation and 6 weeks and 6 months postpartum. Serum levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were assayed via enzyme-linked immunosorbent assay. Thirty-five (20.5%) women reported lifetime exposure to IPV and 7 (4.1%) reported being physically hurt in the preceding 12 months (4 while pregnant). Lifetime exposure to IPV was associated with increased likelihood of experiencing perinatal depression and smoking during pregnancy. Women with a history of IPV had significantly higher levels of TNF-α at 18 weeks (z = -2.29, p < 0.05), but significantly smaller changes in levels of IL-6 (β = -0.36, p = 0.04) across time. Lifetime exposure to IPV was associated with a range of adverse mental health outcomes and may affect proinflammatory cytokine levels in pregnancy.

To analyse the Spanish primary care professionals' readiness to respond to intimate partner violence (IPV) in primary care and identify possible determinants that could facilitate a better response. A cross-sectional study with a non-probabilistic sampling by convenience was performed among healthcare professionals working in 15 primary care centres in Spain. The Physician Readiness to Manage Intimate Partner Violence Survey (PREMIS), the version validated and translated into Spanish, was the instrument used to collect information about knowledge, opinions and practices regarding intimate partner violence. Descriptive analysis and, simple and multiple linear regression analysis were performed. A total of 265 completed questionnaires were received, with a response rate of 80.3%. An exposure-response effect was observed, where at higher hours of training a higher score was obtained on the questionnaire sections (p <0.05). Age, type of profession, years of experience in primary care, hours of IPV training and reading the protocol showed positive association with knowledge (perceived preparation, perceived knowledge, actual knowledge), opinions (staff preparation, legal requirements, self-efficacy, workplace issues, constraints, understanding of the victim) and practice of healthcare professionals. Reading the regional/national protocol for action and receiving training in IPV were the most important interventions associated to a better primary care professionals' readiness to respond to IPV in Spanish primary care settings.

As Intimate Partner Violence (IPV) affects the workplace, a supportive workplace climate is important. The study evaluated the effectiveness of an "IPV and the Workplace" training on workplace climate towards IPV. IPV training was provided to 14 intervention counties and 13 control counties (receiving training 6 months delayed). Measures included workplace climate surveys, IPV knowledge test, and workplace observations. (i) Training significantly improved supervisor knowledge on IPV and received positive evaluations, (ii) training improved workplace climate towards IPV significantly which was maintained over time, and (iii) after the training, supervisors provided more IPV information to employees and more IPV postings were available in the workplace. The study provides evidence to support on-site interactive, computer based training as a means for improved workplace safety. IPV and the Workplace training effectively increased knowledge and positively changed workplace climate. Am. J. Ind.

Intimate partner violence (IPV) perpetration is common among men who use substances. Substance use is a contributing factor for IPV perpetration. This cross-sectional study determined lifetime prevalence and factors associated with ever perpetrating IPV by men receiving substance use treatment in Brazil (n = 281) and England (n = 223). IPV, adverse childhood experiences, attitudes towards gender relations and roles, current health state, substance use, depressive symptoms and anger expression were assessed. Logistic regression determined factors associated with ever perpetrating any (emotional, physical and/or sexual) IPV. Multinomial logistic regression determined factors associated with ever perpetrating different types of IPV. 74.6% (373/500) reported ever perpetrating IPV: 16.5% (82/498) emotional IPV only, 46.4% (231/498) physical IPV (with/without emotional IPV) and 11.6% (58/498) sexual IPV (with/without emotional and/or physical IPV). Higher anger expression, higher depressive symptoms, fighting physically with another man in the past year (Brazil only), experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score (England only) predicted ever perpetrating IPV. Compared to never perpetrating any IPV, anger expression was associated with emotional and physical IPV perpetration; fighting physically with another man in the past year was associated with physical IPV perpetration and experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score were associated with both physical and sexual IPV perpetration. Integrated interventions that address IPV and substance use delivered in substance use treatment could improve outcomes for perpetrators and victims.[Gilchrist G, Radcliffe P, Noto AR, d'Oliveira AFPL.

We describe and compare the baseline rates of victimization and perpetration of three forms of intimate partner violence (IPV)—psychological, physical, and sexual—among sexually active men (n = 1,113) and women (n = 226) enrolled in an ongoing cluster-randomized HIV and gender-based violence prevention trial in Dar es Salaam, Tanzania. IPV was measured using a modified version of the World Health Organization Violence Against Women instrument. We assess the degree to which men and women report overlapping forms of IPV victimization and perpetration. Sociodemographic and other factors associated with increased risk of victimization and perpetration of IPV are examined. Within the last 12 months, 34.8% of men and 35.8% of women reported any form of IPV victimization. Men were more likely than women to report perpetrating IPV (27.6% vs. 14.6%, respectively). We also found high rates of co-occurrence of IPV victimization and perpetration with 69.7% of male perpetrators and 81.8% of female perpetrators also reporting victimization during the last year. Among men, having ever consumed alcohol and experiencing childhood violence were associated with increased risk of most forms of IPV. Younger women were more likely to report perpetrating IPV than older women. We found evidence of gender symmetry with regard to most forms of IPV victimization, but men reported higher rates of IPV perpetration than women. Given the substantial overlap between victimization and perpetration reported, our findings suggest that IPV may be bidirectional within relationships in this setting and warrant further investigation. Implications for interventions are discussed. PMID:26802044

As poliovirus eradication draws closer, alternative Inactivated Poliovirus Vaccines (IPV) are needed to overcome the risks associated with continued use of the Oral Poliovirus Vaccine and of neurovirulent strains used during manufacture of conventional (c) IPV. We have previously demonstrated the susceptibility of the PER.C6(®) cell line to cIPV strains; here we investigated the suspension cell culture platform for growth of attenuated poliovirus strains. We examined attenuated Sabin strain productivity on the PER.C6(®) cell platform compared to the conventional Vero cell platform. The suitability of the suspension cell platform for propagation of rationally-attenuated poliovirus strains (stabilized Sabin type 3 S19 derivatives and genetically attenuated and stabilized MonoCre(X) strains), was also assessed. Yields were quantified by infectious titer determination and D-antigen ELISA using either serotype-specific polyclonal rabbit sera for Sabin strains or monoclonal cIPV-strain-specific antibodies for cIPV, S19 and MonoCre(X) strains. PER.C6(®) cells supported the replication of Sabin strains to yields of infectious titers that were in the range of cIPV strains at 32.5°C. Sabin strains achieved 30-fold higher yields (p<0.0001) on the PER.C6(®) cell platform as compared to the Vero cell platform in infectious titer and D-antigen content. Furthermore, Sabin strain productivity on the PER.C6(®) cell platform was maintained at 10l scale. Yields of infectious titers of S19 and MonoCre(X) strains were 0.5-1 log10 lower than seen for cIPV strains, whereas D-antigen yield and productivities in doses/ml using rationally-attenuated strains were in line with yields reported for cIPV strains. Sabin and rationally-attenuated polioviruses can be grown to high infectious titers and D-antigen yields. Sabin strain infection shows increased productivity on the PER.C6(®) cell platform as compared to the conventional Vero cell platform. Novel cell platforms with the potential for higher yields could contribute to increased affordability of a next generation of IPV vaccines needed for achieving and maintaining poliovirus eradication.

Purpose Because Intimate partner violence (IPV) may disproportionately impact women’s quality of life (QOL) when undergoing cancer treatment, women experiencing IPV were hypothesized to have (a) more symptoms of depression or stress and (b) lower QOL as measured with the Functional Assessment of Cancer Therapy (FACT-B) and Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) Scales relative to those never experiencing IPV. Methods Women, ages 18–79, who were included in one of two state cancer registries from 2009–2015 with a recent incident, primary, invasive biopsy-confirmed cancer diagnosis were recruited and asked to complete a phone interview, within 12 months of diagnosis. This interview measured IPV by timing (current and past) and type (physical, sexual, psychological), socio-demographics, and health status. Cancer registries provided consenting women’s cancer stage, site, date of diagnosis, and age. Results In this large cohort of 3,278 women who completed a phone interview, 1,221 (37.3%) disclosed lifetime IPV (10.6% sexual, 24.5% physical, and 33.6% psychological IPV). Experiencing IPV (particularly current IPV) was associated with poorer cancer-related QOL defined as having more symptoms of depression and stress after cancer diagnosis and lower FACIT-SP and FACT scores than women not experiencing IPV and controlling for confounders including demographic factors, cancer stage, site and number of comorbid conditions. Current IPV was more strongly associated with poorer QOL. When compared with those experiencing past IPV (and no IPV), women with cancer who experienced current IPV had significantly higher depression and stress symptoms scores and lower FACIT-SP and FACT-G scores indicating poorer QOL for all domains. While IPV was not associated with being diagnosed at a later cancer stage, current IPV was significantly associated with having more than one comorbid physical conditions at interview (adjusted rate ratio = 1.35; 95% confidence interval: 1.19–1.54) and particularly for women diagnosed with cancer when <55 years of age. Conclusions Current and past IPV were associated with poorer mental and physical health functioning among women recently diagnosed with cancer. Including clinical IPV screening may improve women’s cancer-related quality of life. PMID:27943059

An inactivated poliovirus vaccine (IPV) based on attenuated poliovirus strains (Sabin-1, -2 and -3) was developed for technology transfer to manufacturers in low- and middle-income countries in the context of the global polio eradication initiative. Safety and immunogenicity of Sabin-IPV (sIPV) was evaluated in a double-blind, randomized, controlled, dose-escalation trial in the target population. Healthy infants (n=20/group) aged 56-63 days, received a primary series of three intramuscular injections with low-, middle- or high-dose sIPV with or without aluminum hydroxide or with the conventional IPV based on wild poliovirus strains (wIPV). Virus-neutralizing titers against both Sabin and wild poliovirus strains were determined before and 28 days after three vaccinations. The incidence of local and systemic reactions was comparable with the wIPV. Seroconversion rates after three vaccinations were 100% for type 2 and type 3 polioviruses (both Sabin and wild strains) and 95-100% for type 1 polioviruses. Median titers were high in all groups. Titers were well above the log2(titer) correlated with protection (=3) for all groups. Median titers for Sabin-2 were 9.3 (range 6.8-11.5) in the low-dose sIPV group, 9.2 (range 6.8-10.2) in the low-dose adjuvanted sIPV group and 9.8 (range 5.5-15.0) in the wIPV group, Median titers against MEF-1 (wild poliovirus type 2) were 8.2 (range 4.8-10.8) in the low-dose sIPV group, 7.3 (range 4.5-10.2) in the low-dose adjuvanted Sabin-IPV group and 10.3 (range 8.5-17.0) in the wIPV group. For all poliovirus types the median titers increased with increasing dose levels. sIPV and sIPV adjuvanted with aluminum hydroxide were immunogenic and safe at all dose levels, and comparable with the wIPV.

To determine whether adults who witnessed intimate partner violence (IPV) as children would have an increased rate of being victims of ongoing IPV, as measured by the Ongoing Violence Assessment Tool (OVAT), compared with adult controls who did not witness IPV as children. The authors also sought to determine whether there were differences in demographics in these two groups. This was a cross sectional cohort study of patients presenting to a high-volume academic emergency department. Emergency department patients presenting from November 16, 2005, to January 5, 2006, during 46 randomized four-hour shifts were included. A confidential computer touch-screen data entry program was used for collecting demographic data, including witnessing IPV as a child and the OVAT. Main outcome measures were witnessing IPV as a child, ongoing IPV, and associated demographics. Assuming a prevalence of IPV of 20% and a clinically significant difference of 20% between adults who witnessed IPV as children and adult controls who did not witness IPV as children, the study was powered at 80%, with 215 subjects included. A total of 280 subjects were entered; 256 had complete data sets. Forty-nine percent of subjects were male, 45% were Hispanic, 72 (28%) were adults who witnessed IPV as children, and 184 (72%) were adult controls who did not witness IPV as children. Sixty-three (23.5%) were positive for ongoing IPV. There was no correlation of adults who witnessed IPV as children with the presence of ongoing IPV, as determined by univariate and bivariate analysis. Twenty-three of 72 (32%) of the adults who witnessed IPV as children, and 39 of 184 (21%) of the adult controls who did not witness IPV as children, were positive for IPV (difference, 11%; 95% confidence interval [CI] = -2% to 23%). Significant correlations with having witnessed IPV as a child included age younger than 40 years (odds ratio [OR], 4.2; 95% CI = 1.7 to 9.1), income less than $20,000/year (OR, 5.1; 95% CI = 1.6 to 12.5), and abuse as a child (OR, 9.1; 95% CI = 4.2 to 19.6). Other demographics were not significantly correlated with having witnessed IPV as a child. Adults who witnessed IPV as children were more likely to have a lower income, be younger, and have been abused as a child, but not more likely to be positive for ongoing IPV, when compared with patients who had not witnessed IPV.

The specification for the File Transfer Protocol (FTP) assumes that the underlying network protocols use a 32-bit network address and a 16-bit transport address (specifically IP version 4 and TCP). With the deployment of version 6 of the Internet Protocol, network addresses will no longer be 32-bits. This paper species extensions to FTP that will allow the protocol to work over a variety of network and transport protocols.

Women in Bangladesh experience high rates of Intimate Partner Violence (IPV). IPV is more prevalent against income earning women compared to their non-earning counterparts, and Workplace Violence (WPV) is also common. Such violence is a violation of women's rights, and also constrains them from contributing to their personal growth, household, community and the economy at large. There is limited evidence on what works to prevent IPV and WPV amongst garment workers. This paper describes an evaluation of HERrespect, an intervention which aims to reduce IPV and WPV against female garment workers in and around Dhaka, Bangladesh. The trial employs a quasi-experimental design, with four intervention and four control factories. In the intervention factories a randomly selected cohort of married female line workers, a cohort of male line workers, and all middle management staff received the intervention. The intervention strategies involved (1) gender transformative group-based training for workers and management staff; (2) joint session between workers (15 female and male) and middle-management staff; (3) factory-wide activities; (4) awareness raising among top management; (5) factory policy review and development and 6) a community based campaign. For the evaluation, a cohort of randomly selected female workers and a cohort of selected management staff have been established. All workers (n = 800) and management staff (n = 395) from these cohorts were interviewed at baseline using two different questionnaires, and will be interviewed in the endline, 24 months post-baseline. Intention to treat analysis will be used for assessing the impact of HERrespect, comparing the intervention and control factories. To our knowledge this is the first study that seeks to evaluate the impact on IPV and WPV, of group sessions with female workers, male workers, and management; factory-wide campaigns and a community intervention among female garment workers in Bangladesh. Apart from informing programmers and policy makers about intervention effectiveness in reducing IPV and WPV against female garment workers this study will also present evidence on an intervention tailored to the situation in the garment sector, which makes HERrespect scalable.

Since April 2016 inactivated poliovirus vaccine (IPV) has been the only routine source of polio type 2 protection worldwide. With IPV supply constraints, data on comparability of immunogenicity and safety will be important to optimally utilize available supplies from different manufacturers. In this multicenter phase IV study, 900 Latin American infants randomly assigned to six study groups received three doses of bOPV at 6, 10 and 14weeks and either one IPV dose at 14weeks (groups SP-1, GSK-1 and BBio-1) or two IPV doses at 14 and 36weeks (groups SP-2, GSK-2 and BBio-2) from three different manufacturers. Children were challenged with mOPV2 at either 18 (one IPV dose) or 40weeks (two IPV doses) and stools were collected weekly for 4weeks to assess viral shedding. Serum neutralizing antibodies were measured at various time points pre and post vaccination. Serious adverse events and important medical events (SAE and IME) were monitored for 6months after last study vaccine. At week 18, 4weeks after one dose of IPV, overall type 2 seroconversion rates were 80.4%, 80.4% and 73.3% for SP-1, GSK-1 and BBio-1 groups, respectively; and 92.6%, 96.8% and 88.0% in those who were seronegative before IPV administration. At 40weeks, 4weeks after a second IPV dose, type 2 seroconversion rates were ≥99% for any of the three manufacturers. There were no significant differences in fecal shedding index endpoint (SIE) after one or two IPV doses (SP: 2.3 [95% CI: 2.1-2.6]); GSK: 2.2 [1.7-2.5]; BBio 1.8 [1.5-2.3]. All vaccines appeared safe, with no vaccine-related SAE or IME. Current WHO prequalified IPV vaccines are safe and induce similar humoral and intestinal immunity after one or two doses.

2017-06-01
This study examined whether police involvement in intimate partner violence (IPV) is associated with children's anxiety symptoms and threat appraisals. Participants were 117 mothers and their children (7-10 years) recruited from domestic violence shelters and followed for 6 months. Mothers reported on IPV and police involvement in the past 6 months; children reported their own anxiety symptoms and threat appraisals. Police involvement in IPV incidents at Time 1 was positively related to children's anxiety symptoms at both the Time 1 and Time 2 assessments, even after controlling for the severity of the IPV. Police involvement was not associated with children's threat appraisals. Police involvement in IPV may inadvertently contribute to an increase in children's anxiety symptoms. Efforts to mitigate adverse outcomes should be investigated.

The introduction of the inactivated poliovirus vaccine (IPV) represents a crucial step in the polio eradication endgame. This trial examined the safety and immunogenicity of IPV given alongside the measles-rubella and yellow fever vaccines at 9 months and when given as a full or fractional dose using needle and syringe or disposable-syringe jet injector. We did a phase 4, randomised, non-inferiority trial at three periurban government clinics in west Gambia. Infants aged 9-10 months who had already received oral poliovirus vaccine were randomly assigned to receive the IPV, measles-rubella, and yellow fever vaccines, singularly or in combination. Separately, IPV was given as a full intramuscular or fractional intradermal dose by needle and syringe or disposable-syringe jet injector at a second visit. The primary outcomes were seroprevalence rates for poliovirus 4-6 weeks post-vaccination and the rate of seroconversion between baseline and post-vaccination serum samples for measles, rubella, and yellow fever; and the post-vaccination antibody titres generated against each component of the vaccines. We did a per-protocol analysis with a non-inferiority margin of 10% for poliovirus seroprevalence and measles, rubella, and yellow fever seroconversion, and (1/3) log2 for log2-transformed antibody titres. This trial is registered with ClinicalTrials.gov, number NCT01847872. Between July 10, 2013, and May 8, 2014, we assessed 1662 infants for eligibility, of whom 1504 were enrolled into one of seven groups for vaccine interference and one of four groups for fractional dosing and alternative route of administration. The rubella and yellow fever antibody titres were reduced by co-administration but the seroconversion rates achieved non-inferiority in both cases (rubella, -4·5% [95% CI -9·5 to -0·1]; yellow fever, 1·2% [-2·9 to 5·5]). Measles and poliovirus responses were unaffected (measles, 6·8% [95% CI -1·4 to 14·9]; poliovirus serotype 1, 1·6% [-6·7 to 4·7]; serotype 2, 0·0% [-2·1 to 2·1]; serotype 3, 0·0% [-3·8 to 3·9]). Poliovirus seroprevalence was universally high (>97%) after vaccination, but the antibody titres generated by fractional intradermal doses of IPV did not achieve non-inferiority compared with full dose. The number of infants who seroconverted or had a four-fold rise in titres was also lower by the intradermal route. There were no safety concerns. The data support the future co-administration of IPV, measles-rubella, and yellow fever vaccines within the Expanded Programme on Immunization schedule at 9 months. The administration of single fractional intradermal doses of IPV by needle and syringe or disposable-syringe jet injector compromises the immunity generated, although it results in a high post-vaccination poliovirus seroprevalence.

Intimate partner violence (IPV) victimization is a prevalent issue among women residing in Mexico City. Comprehensive and integrated health care provider (HCP) delivered programs in clinic-settings are needed, yet few have been evaluated in Latin America, including Mexico. In addition, there has been minimal attention to interventions among lower income women presenting at settings outside of antenatal care clinics. The current randomized controlled trial seeks to increase midlevel HCPs' capacity, specifically nurses, who are often the first point of contact in this setting, to identify women presenting at health clinics with experiences of IPV and to assist these women with health risk mitigation. Specific outcomes include changes in past-year IPV (physical and/or sexual), reproductive coercion, safety planning, use of community resources, and quality of life. Forty-two public health clinics in Mexico City were randomized to treatment or control clinics. Nurses meeting eligibility criteria in treatment groups received an intensive training on screening for IPV, providing supportive referrals, and assessing for health and safety risks. Nurses meeting eligibility criteria at control clinics received the standard of care which included a one-day training focused on sensitizing staff to IPV as a health issue and referral cards to give to women. Women were screened for eligibility (currently experiencing abuse in a heterosexual relationship, 18-44 years of age, non-pregnant or in first trimester) by research assistants in private areas of waiting rooms in health clinics. Consenting women completed a baseline survey and received the study protocol for that clinic. In treatment clinics, women received the nurse delivered session at baseline and received a follow-up counseling session after three months. Surveys are conducted at baseline, three months, and fifteen months from baseline. This study will provide important insight into whether a nurse-delivered program can assist women currently experiencing abuse in a Latin American context. Findings can be used to inform IPV programs and policies in Mexico City's public health clinics. NCT01661504.

Background Nonadherence to immunosuppressants is associated with rejection and allograft loss. Intrapatient variability (IPV) of immunosuppression levels is a marker of nonadherence. This study describes the impact of IPV of tacrolimus levels in patients receiving a tacrolimus monotherapy immunosuppression protocol. Methods We retrospectively analyzed the outpatient tacrolimus levels of kidney-only transplant patients taken between 6 and 12 months posttransplant. IPV was determined using the coefficient of variance. Results Six hundred twenty-eight patients with a mean number of 8.98 ± 3.81 tacrolimus levels and a mean follow-up of 4.72 ± 2.19 years were included. Multivariate analysis showed death was associated with increasing age (1.04 [1.01-1.07], P = 0.0055), diabetes at time of transplant (2.79 [1.44-5.41], P = 0.0024), and rejection (2.34 [1.06-5.19], P = 0.036). Variables associated with graft loss included the highest variability group (2.51 [1.01-6.27], P = 0.048), mean tacrolimus level less than 5 ng/mL (4.32 [1.94-9.63], P = 0.0003), a high clinic nonattendance rate (1.10 [1.01-1.20], P = 0.03), and rejection (9.83 [4.62-20.94], P < 0.0001). Independent risk factors for rejection were de novo donor-specific antibody (3.15 [1.84-5.39], P < 0.0001), mean tacrolimus level less than 5 ng/mL (2.57 [1.27-5.19], P = 0.00860, and a high clinic nonattendance rate (1.11 [1.05-1.18], P = 0.0005). Conclusions This study shows that high tacrolimus IPV and clinic nonattendance are associated with inferior allograft survival. Interventions to minimize the causes of high variability, particularly nonadherence are essential to improve long-term allograft outcomes. PMID:28795143

Intimate partner violence (IPV), substance use, and HIV are often co-occuring health problems affecting low-income urban women, and have been described as connected epidemics making up a "syndemic." Research suggests that each issue separately is associated with depressive symptoms, but no studies have examined the combined effect of IPV, substance use and HIV on women's depression. Interviews were conducted with 96 women recruited from community health clinics serving low-income women in an urban U.S. city. All women were over 17, not pregnant, English-speaking, without private insurance and had experienced physical IPV in the past year. Women were primarily African American (82%) and 82% were receiving income assistance. Twenty seven percent were HIV-positive, and 27% had used heroin or cocaine in the past 6 months. Based on the Centers for Epidemiological Studies Depression Scale (CES-D ), 73% were depressed. Women who experienced severe IPV in the past 6 months were compared to women who experienced no IPV or psychological IPV only in the past 6 months; those who experienced severe IPV were 5.3 times more likely to be depressed, controlling for HIV status, drug use, age, and relationship status. Women who experienced severe IPV, were HIV-positive, and used drugs (7.3% of sample) were 7.98 times as likely to be depressed as women without these characteristics. These findings confirm that severe IPV is significantly associated with depression among urban abused women. Furthermore, this research suggests that the syndemic effect of IPV, substance use, and HIV could be even more detrimental to women's mental health. Health practitioners and researchers should be aware of the combined impact of the IPV, substance use, and HIV syndemic and consider how they can address the mental health needs of urban women.

Combination vaccines represent one solution to the problem of increased numbers of injections during single clinic visits. A combined DTaP-IPV (Infanrix-IPV) vaccine has been developed for use as a pre-school booster. Four hundred healthy children aged 4-6 years previously primed with 4 doses of DTaP vaccine (Infanrix), 3 doses of poliovirus vaccine and 1 dose of MMR vaccine were randomized to receive single doses of either the combined DTaP-IPV vaccine or separate DTaP and IPV vaccines in a Phase II trial (DTaP-IPV-047). All children also received a second dose of MMR vaccine. Immunogenicity was assessed in serum samples taken before and 1 month after booster administration. Safety was actively assessed for 42 days post-vaccination. Non-inferiority of the DTaP-IPV vaccine to separate DTaP and IPV vaccines was demonstrated for all DTaP antigen booster response rates and poliovirus geometric mean titers of antibody ratios. Post-vaccination, > or =99.4% of children in both groups had seroprotective levels of anti-diphtheria and anti-tetanus antibodies (> or =0.1IU/mL) and seroprotective anti-poliovirus antibody titers (> or =1:8). All children in both groups were seropositive for measles, mumps and rubella antibodies, with similar post-vaccination geometric mean concentrations/titers. No significant differences were observed in the incidence of solicited local or general symptoms, unsolicited symptoms and serious adverse events between the two groups. This combined DTaP-IPV appeared safe and immunogenic when given as a booster dose at 4-6 years of age. The DTaP-IPV vaccine had no negative effect on the response to co-administered MMR vaccine, making it well-suited for use as a pre-school booster.

Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruption. Mobile IPv6 was proposed to provide mobility support to IPv6-based mobile nodes for continuous communication when they roam across different networks. However, the Route Optimization procedure in Mobile IPv6 involves the verification of mobile node's reachability at the home address and at the care-of address (home test and care-of test) that results in higher handover delays and signalling overhead. This paper presents an enhanced procedure, time-based one-time password Route Optimization (TOTP-RO), for Mobile IPv6 Route Optimization that uses the concepts of shared secret Token, time based one-time password (TOTP) along with verification of the mobile node via direct communication and maintaining the status of correspondent node's compatibility. The TOTP-RO was implemented in network simulator (NS-2) and an analytical analysis was also made. Analysis showed that TOTP-RO has lower handover delays, packet loss, and signalling overhead with an increased level of security as compared to the standard Mobile IPv6's Return-Routability-based Route Optimization (RR-RO).

Intimate partner violence (IPV), including physical, sexual, emotional, and economic violence, has profound immediate and long-term effects on individuals and communities worldwide. To date, few studies have focused on couples' reporting of IPV. The aim of this article is to present the results of a survey of couples' reporting of IPV and the individual, interpersonal, and social correlates of IPV in northern Tanzania. Four hundred fifty couples from Karatu District, Tanzania, completed a questionnaire measuring attitudes on gender norms and relations, men's experience of childhood trauma, and men's perpetration and women's experience of IPV. We found high levels of acceptance and experience of IPV: 72% of men justified a husband's perpetration of IPV, and 54% of men and 76% of women said that a woman should tolerate violence to keep her family together. The majority of women had ever experienced IPV (77.8%), and 73.6% and 69% had experienced IPV in the past 12 and 3 months, respectively. Men were significantly less likely to report that they had committed IPV: 63.6% ever, 48.9% in the past 12 months, and 46.2% in the past 3 months. Multivariate logistic regression found that younger men, men who reported gender inequitable attitudes, childhood trauma, multiple sexual partners, and alcohol use were significantly more likely to report IPV perpetration in the past 3 months. Younger women, and women with low levels of education and reported food shortages were significantly more likely to report IPV in the past 3 months. These results indicate that social and individual acceptance and justification of IPV are common. Experience of violence persists over time in many relationships. This study demonstrates the need for interventions that address individual-, interpersonal-, and community-level determinants of IPV, including attitudes regarding gender equity, exposure to violence as children and intergenerational violence, lack of education, and poverty.

Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations, with increasing evident that gay men experience IPV at the same rates as heterosexual women. This study examines the relationship between self-reported condomless anal intercourse (CAI) and IPV among a sample of 750 gay and bisexual men. Participants answered questions regarding recent receipt and perpetration of IPV using the IPV-GBM Scale (Cronbach Alpha 0.90). Of the sample, 46.1% reported recent receipt of any type of IPV and 33.6% reported recent perpetration of any type of IPV. Overall, 55.1% of participants reported CAI at last sex. Significant associations were determined between several forms of IPV and increased odds of reporting CAI at last sex. These findings suggest that IPV may be a risk factor for CAI among men who have sex with men, and highlight the need to understand the IPV prevention and care needs of this population.

Objectives were to assess associations between intimate partner violence (IPV), violence during armed conflict (i.e. crisis violence), and probable post-traumatic stress disorder (PTSD). Using a sample of 950 women in rural Côte d'Ivoire, logistic generalized estimating equations assessed associations between IPV and crisis violence exposures with past-week probable PTSD. Over one in 5 (23.4%) women reported past-year IPV, and over one in 4 women (26.5%) reported experiencing IPV prior to the past year (i.e. remote IPV). Crisis violence was experienced by 72.6% of women. In adjusted models including demographics, crisis violence (overall and specific forms), and IPV (remote and past-year), women who reported past-year IPV had 3.1 times the odds of reporting probable past-week PTSD (95%CI: 1.8-5.3) and those who reported remote IPV had 1.6 times the odds (95%CI: 0.9-2.7). Violent exposures during the crisis were not significantly associated with probable PTSD (any crisis violence: aOR: 1.04 (0.7-1.5); displacement: aOR: 0.9 (95%CI: 0.5-1.7); family victimization during crisis: aOR: 1.1 (95%CI: 0.8-1.7); personal victimization during crisis: aOR: 1.7 (95%CI: 0.7-3.7)). Past-year IPV was more strongly associated with past-week probable PTSD than remote IPV and violence directly related to the crisis. IPV must be considered within humanitarian mental health and psychosocial programming.

To ensure that developing countries have the option to produce inactivated poliovirus vaccine (IPV), the Global Polio Eradication Initiative has promoted the development of an IPV using Sabin poliovirus strains (Sabin IPV). This trial assessed the reactogenicity and immunogenicity of Sabin IPV and adjuvanted Sabin IPV in healthy adults in Cuba. This is a randomized, controlled phase I trial, enrolling 60 healthy (previously vaccinated) male human volunteers, aged 19-23 years to receive one dose of either Sabin IPV (20:32:64 DU/dose), adjuvanted Sabin IPV (10:16:32 DU/dose), or conventional Salk IPV (40:8:32 DU/dose). The primary endpoint for reactogenicity relied on monitoring of adverse events. The secondary endpoint measured boosting immune responses (i.e. seroconversion or 4-fold rise) of poliovirus antibody, assessed by neutralization assays. Sixty subjects fulfilled the study requirements. No serious adverse events reported were attributed to trial interventions during the 6-month follow-up period. Twenty-eight days after vaccination, boosting immune responses against poliovirus types 1-3 were between 90% and 100% in all vaccination groups. There was a more than 6-fold increase in median antibody titers between pre- and post-vaccination titers in all vaccination groups. Both Sabin IPV and adjuvanted Sabin IPV were well tolerated and immunogenic against all poliovirus serotypes. This result suggests that the aluminum adjuvant may allow a 50% (or higher) dose reduction. Copyright © 2014. Published by Elsevier Ltd.

Children are frequently present in homes in which intimate partner violence (IPV) occurs. Following exposure to IPV, children may develop behavioral health difficulties, struggle with regulating emotions, or exhibit aggression. Despite the negative outcomes associated with witnessing IPV, many children also display resilience. Guided by Bronfenbrenner's bioecological model, this study examined person-level, process-level (microsystem), and context-level (mesosystem) factors associated with positive and negative functioning among youth exposed to IPV. Participants were 118 mothers who reported on their 6- to 14-year-old children. All mothers experienced severe physical, psychological, and/or sexual IPV in the past 6 months. Linear regression modeling was conducted separately for youth maladaptive functioning and prosocial skills. The linear regression model for maladaptive functioning was significant, F(6, 110) = 9.32, p < .001, adj R 2 = 27%, with more severe IPV (β = .18, p < .05) and more negative parenting practices (β = .34, p < .001) associated with worse child outcomes. The model for prosocial skills was also significant, F(6, 110) = 3.34, p < .01, adj. R 2 = 14%, with less negative parenting practices (β = -.26, p < .001) and greater community connectedness (β = .17, p < .05) linked to more prosocial skills. These findings provide critical knowledge on specific mutable factors associated with positive and negative functioning among children in the context of IPV exposure. Such factors could be incorporated into strength-based interventions following family violence.

Violence against women is recognized by globally as a serious health and social problem that impedes development. To determine the magnitude of physical intimate partner violence against women in six selected communities from Chile, Egypt, India and the Philippines. Population-based household surveys. Selected urban communities in Temuco, Chile; Ismailia, Egypt; Lucknow, Trivandrum, and Vellore non-slum areas of India; and in Manila, the Philippines. Women aged 15-49 years who cared for at least one child younger than 18 years old. The number of participants per community was 442 (Santa Rosa, Chile), 631 (El-Sheik Zayed, Egypt), 506 (Lucknow, India), 700 (Trivandrum, India), 716 (Vellore, India) and 1000 (Paco, the Philippines). Lifetime and Current physical intimate partner violence (IPV) was measured using standard definitions and four behaviors of actions--namely slap, hit, kick and beat. Three derived variables for severity included: disabling IPV, IPV-related injury requiring health care and multiple severe IPV (presence of hit and kick and beat). Percentages of lifetime and current physical intimate partner violence (IPV) against women in our sample of 3975 were as follows: 24.9 and 3.6 (Santa Rosa), 11.1 and 10.5 (El-Sheik Zayed), 34.6 and 25.3 (Lucknow), 43.1 and 19.6 (Trivandrum) 31.0 and 16.2 (Vellore), and 21.2 and 6.2 (Paco). Multiple severe physical IPV was more common in the three communities within India (9.0%, 5.9% and 8.0% in Trivandrum, Lucknow and Vellore) than the other three communities (Santa Rosa 2.1%; El-Sheik Zayed 2.9% and Paco 1.9%). Physical IPV was found to be a common phenomenon in all six communities. Overall, patterns of IPV behaviors were similar among the six communities.

This follow-up study assessed the 5-year persistence of vaccine-induced antibodies (Td-IPV or DT-IPV) and the immune response to a booster dose of DTaP-IPV. This was an open-label, parallel-group (two arms), multicentre trial performed at 44 study sites in France. Children aged 11-13 years, of either sex, who received Td-IPV (Revaxis(®)) and DT-IPV (DT Polio(®)) vaccines at 6 years of age in one previous open-label trial with no further vaccination against diphtheria, tetanus, pertussis or poliomyelitis, were enrolled. All participants received a single intramuscular booster dose (0.5mL) of DTaP-IPV vaccine (Tetravac-Acellulaire(®)). Study endpoints were based on antibody persistence and post-booster immune responses. Safety was monitored throughout the study. Descriptive statistics were used for all analyses. Of the 758 children included in the previous study, 274 were included in this follow-up study; 129 had previously been vaccinated with Td-IPV, and 145 had previously received DT-IPV. At least 96.5% of participants in both groups presented an anti-diphtheria and anti-tetanus concentration ≥0.01IU/mL, and anti-poliovirus types 1-3 titres≥8 (1/dilution). Following vaccination with DTaP-IPV, anti-diphtheria and anti-tetanus antibody concentrations ≥0.1IU/mL and anti-poliovirus types 1-3 antibody titres ≥8 (1/dilution) were achieved in all participants. DTaP-IPV was well tolerated in this study. There were no serious adverse events during the study, and no participant withdrew because of adverse events. The present study confirmed the long-term immunity conferred by Td-IPV when given as a booster dose, and supports the use of Td-IPV as a second booster at 6 years of age in children previously vaccinated against diphtheria, tetanus and poliomyelitis types 1-3.

Abstract: Background: There has been increased advocacy to involve healthcare providers in the prevention of intimate partner violence (IPV) through screening for it in healthcare. Yet, only one in ten providers screen for IPV, suggesting barriers. Understanding the readiness of healthcare providers to screen for IPV is therefore paramount. The Domestic Violence Healthcare Provider Survey Scales (DVHPSS) is a previously validated, comprehensive scale to study readiness of healthcare providers to screen for IPV. However, an understanding of its usefulness in the Sub-Saharan African context remains elusive. The current study undertook to examine the structural validity of the DVHPSS in Nigeria. Methods: Exploratory factor analysis and Cronbach's Alpha were run to reveal the factorial structure and reliability of the instrument/subscales respectively. Established thresholds were used to determine significant factor loadings and alphas coefficient. Results: A six factor model emerged, with 2 factors similar to the original scale, another two differing slightly and a further two factors resulting from a splitting up of the original combination of victim/provider safety to having distinct victim and provider safety subscales. Conclusions: With slight modifications, the DVHPSS can be use to study IPV screening among Nigerian healthcare professionals. Introducing screening protocols could promote better understanding of crucial questions that were lost in the analysis. PMID:21483202

Sexual intimate partner violence (IPV) is a public health problem worldwide. Research regarding beliefs about perpetrating sexual IPV is, however, limited. This study investigated attitudes, social influence, and self-efficacy beliefs and intentions toward perpetrating sexual IPV among Grade 8 adolescents ( M age = 13.73, SD = 1.04) in the Western Cape Province of South Africa. The study sample was taken from the baseline data of the Promoting sexual and reproductive health among adolescents in Southern and Eastern Africa (PREPARE) study, a cluster-randomized controlled trial. Young adolescents ( N = 2,199), from 42 randomly selected high schools, participated in the study and answered a paper-and-pencil questionnaire. Multivariate ANOVA were conducted to assess differences in beliefs and intention toward perpetrating sexual IPV between boys and girls, and between perpetrators and nonperpetrators. Results showed that boys were more frequently perpetrators (11.3% vs. 3.2%) and victims (13.6% vs. 6.4%) of sexual IPV than girls. Boys' attitudes toward perpetrating sexual IPV were more supportive than girls'. Boys perceived their social network to be more likely to think that putting pressure on a boyfriend or girlfriend to have sex is okay, and boys had a lower self-efficacy to refrain from pressuring a boyfriend or girlfriend to have sex compared with girls. Both boys and girls, who have perpetrated sexual IPV, had more tolerant attitude, social influence, and self-efficacy beliefs toward sexual IPV perpetration, compared with nonperpetrators. Intention not to perpetrate sexual IPV did not differ between boys and girls, or between perpetrators and nonperpetrators. Our findings suggest that interventions should address attitude and social influence beliefs regarding sexual IPV perpetration. More attention should be given to sexual IPV perpetration among boys. Given that sexual IPV victimization and perpetration are significantly linked, prevention of sexual IPV perpetration seems to be of utmost importance.

In August 2012, the Brazilian Ministry of Health introduced inactivated polio vaccine (IPV) as part of sequential polio vaccination schedule for all infants beginning their primary vaccination series. The revised childhood immunization schedule included 2 doses of IPV at 2 and 4 months of age followed by 2 doses of oral polio vaccine (OPV) at 6 and 15 months of age. One annual national polio immunization day was maintained to provide OPV to all children aged 6 to 59 months. The decision to introduce IPV was based on preventing rare cases of vaccine-associated paralytic polio, financially sustaining IPV introduction, ensuring equitable access to IPV, and preparing for future OPV cessation following global eradication. Introducing IPV during a national multivaccination campaign led to rapid uptake, despite challenges with local vaccine supply due to high wastage rates. Continuous monitoring is required to achieve high coverage with the sequential polio vaccine schedule. PMID:25316829

Due to the proliferation of handheld mobile devices, multimedia applications like Voice over IP (VoIP), video conferencing, network music, and online gaming are gaining popularity in recent years. These applications are well known to be delay sensitive and resource demanding. The mobility of mobile devices, running these applications, across different networks causes delay and service disruption. Mobile IPv6 was proposed to provide mobility support to IPv6-based mobile nodes for continuous communication when they roam across different networks. However, the Route Optimization procedure in Mobile IPv6 involves the verification of mobile node's reachability at the home address and at the care-of address (home test and care-of test) that results in higher handover delays and signalling overhead. This paper presents an enhanced procedure, time-based one-time password Route Optimization (TOTP-RO), for Mobile IPv6 Route Optimization that uses the concepts of shared secret Token, time based one-time password (TOTP) along with verification of the mobile node via direct communication and maintaining the status of correspondent node's compatibility. The TOTP-RO was implemented in network simulator (NS-2) and an analytical analysis was also made. Analysis showed that TOTP-RO has lower handover delays, packet loss, and signalling overhead with an increased level of security as compared to the standard Mobile IPv6's Return-Routability-based Route Optimization (RR-RO).

Trivalent oral polio vaccine (tOPV) was replaced worldwide from April, 2016, by bivalent types 1 and 3 oral polio vaccine (bOPV) and one dose of inactivated polio vaccine (IPV) where available. The risk of transmission of type 2 poliovirus or Sabin 2 virus on re-introduction or resurgence of type 2 poliovirus after this switch is not understood completely. We aimed to assess the risk of Sabin 2 transmission after a polio vaccination campaign with a monovalent type 2 oral polio vaccine (mOPV2). We did an open-label cluster-randomised trial in villages in the Matlab region of Bangladesh. We randomly allocated villages (clusters) to either: tOPV at age 6 weeks, 10 weeks, and 14 weeks; or bOPV at age 6 weeks, 10 weeks, and 14 weeks and either one dose of IPV at age 14 weeks or two doses of IPV at age 14 weeks and 18 weeks. After completion of enrolment, we implemented an mOPV2 vaccination campaign that targeted 40% of children younger than 5 years, regardless of enrolment status. The primary outcome was Sabin 2 incidence in the 10 weeks after the campaign in per-protocol infants who did not receive mOPV2, as assessed by faecal shedding of Sabin 2 by reverse transcriptase quantitative PCR (RT-qPCR). The effect of previous immunity on incidence was also investigated with a dynamical model of poliovirus transmission to observe prevalence and incidence of Sabin 2 virus. This trial is registered at ClinicalTrials.gov, number NCT02477046. Between April 30, 2015, and Jan 14, 2016, individuals from 67 villages were enrolled to the study. 22 villages (300 infants) were randomly assigned tOPV, 23 villages (310 infants) were allocated bOPV and one dose of IPV, and 22 villages (329 infants) were assigned bOPV and two doses of IPV. Faecal shedding of Sabin 2 in infants who did not receive the mOPV2 challenge did not differ between children immunised with bOPV and one or two doses of IPV and those who received tOPV (15 of 252 [6%] vs six of 122 [4%]; odds ratio [OR] 1·29, 95% CI 0·45-3·72; p=0·310). However, faecal shedding of Sabin 2 in household contacts was increased significantly with bOPV and one or two doses of IPV compared with tOPV (17 of 751 [2%] vs three of 353 [1%]; OR 3·60, 95% CI 0·82-15·9; p=0·045). Dynamical modelling of within-household incidence showed that immunity in household contacts limited transmission. In this study, simulating 1 year of tOPV cessation, Sabin 2 transmission was higher in household contacts of mOPV2 recipients in villages receiving bOPV and either one or two doses of IPV, but transmission was not increased in the community as a whole as shown by the non-significant difference in incidence among infants. Dynamical modelling indicates that transmission risk will be higher with more time since cessation. Bill & Melinda Gates Foundation. Copyright © 2017 The Author(s). Published by Elsevier Ltd.

Perinatal intimate partner violence (IPV) is common and has significant negative health outcomes for mothers and infants. This study evaluated the effectiveness of an IPV intervention in reducing violence among abused women in perinatal home visiting programs. This assessor-blinded multisite randomized control trial of 239 women experiencing perinatal IPV was conducted from 2006 to 2012 in U.S. urban and rural settings. The Domestic Violence Enhanced Home Visitation Program (DOVE) intervention group (n = 124) received a structured abuse assessment and six home visitor-delivered empowerment sessions integrated into home visits. All participants were screened for IPV and referred appropriately. IPV was measured by the Conflicts Tactics Scale2 at baseline through 24 months postpartum. There was a significant decrease in IPV over time (F = 114.23; p < 0.001) from baseline to 1, 3, 6, 12, 18, and 24 months postpartum (all p < 0.001). Additional models examining change in IPV from baseline indicated a significant treatment effect (F = 6.45; p < 0.01). Women in the DOVE treatment group reported a larger mean decrease in IPV scores from baseline compared to women in the usual care group (mean decline 40.82 vs. 35.87). All models accounted for age and maternal depression as covariates. The DOVE intervention was effective in decreasing IPV and is brief, thereby facilitating its incorporation within well-woman and well-child care visits, as well as home visiting programs, while satisfying recommendations set forth in the Affordable Care Act for IPV screening and brief counseling.

Background: Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (dTpa-IPV; GSK Biologicals Boostrix™-Polio; 3-component pertussis) vs. full-strength DTPa-IPV vaccine (sanofi-pasteur—MSD Tetravac™; 2-component pertussis) was evaluated in pre-school Italian children. Methods: Healthy children aged 5–6 y primed in a routine vaccination setting with three doses of DTPa-based vaccines were enrolled and randomized (1:1) in this phase IIIb, booster study to receive a single dose of dTpa-IPV or DTPa-IPV; the MMRV vaccine was co-administered. Antibody concentrations/titers against diphtheria, tetanus, pertussis and poliovirus 1–3 were measured before and one month post-booster. Reactogenicity and safety was assessed. Results: 305 subjects were enrolled of whom 303 (dTpa-IPV = 151; DTPa-IPV = 152) received booster vaccination. One month post-booster, all subjects were seroprotected/seropositive for anti-diphtheria, anti-tetanus, anti-PT, anti-FHA and anti-poliovirus 1–3; 99.3% of dTpa-IPV and 60.4% of DTPa-IPV subjects were seropositive for anti-PRN; 98–100% of subjects were seropositive against MMRV antigens post-booster. Pain at the injection site (dTpa-IPV: 63.6%; DTPa-IPV: 63.2%) and fatigue (dTpa-IPV: 26.5%; DTPa-IPV: 23.7%) were the most commonly reported solicited local and general symptoms, during the 4-d follow-up period. No SAEs or fatalities were reported. Conclusions: The reduced-antigen-content dTpa-IPV vaccine was non-inferior to full-strength DTPa-IPV vaccine with respect to immunogenicity. The vaccine was well-tolerated and can be confidently used as a booster dose in pre-school children. PMID:22327497

Intimate partner violence (IPV) is a significant public health problem with a demonstrated link to increased sexually transmitted infection (STI)/HIV-related risk and vulnerability. While IPV is an important issue in Central America, the link to STI/HIV risk has not been explored in this region. In this study, the relationship between emotional and physical/sexual IPV and the STI/HIV-related risk behaviors of sex worker patronage and infidelity is assessed among male IPV perpetrators using data from a national survey conducted in 2009 in Guatemala (n = 4773 married/partnered men). Bivariate associations between background characteristics and emotional and physical IPV perpetration were explored. Logistic regression models were run to test associations between IPV for each sexual risk behavior. Perpetration of emotional and physical/sexual IPV was more common among married/partnered men who were older than 24, had more education, lived in urban areas, or were in common law versus married unions. Reports of past-year emotional IPV perpetration increased as wealth quintile increased. After adjusting for demographics and other characteristics, physical/sexual IPV perpetration was associated with past-year infidelity (AOR 1.9, 95% CI: 1.1-3.6). Lifetime emotional IPV (AOR 1.4, 95% CI: 1.1-1.7) and physical/sexual IPV 1.6 (95% CI 1.2-2.0) were positively associated with a history of sex worker patronage. Endorsement of traditional gender role norms showed a marginally positive association with past-year infidelity in the adjusted model (AOR 1.3, 95% CI 1.0-1.8). The study findings from Guatemala reinforce the growing evidence globally that male IPV perpetrators are more likely to engage in risky sexual behavior, including sex worker patronage and main partner infidelity. The concurrency of violence and increased STI/HIV risk may compound the health risks for female victims of IPV who also face injury and psychological trauma. Integration of prevention and screening of IPV and STI/HIV prevention services should be adopted in Guatemala and other similar contexts.

We examined whether frequent drug use increases the likelihood of subsequent sexual or physical intimate partner violence (IPV) and whether IPV increases the likelihood of subsequent frequent drug use. A random sample of 416 women on methadone was assessed at baseline (wave 1) and at 6 months (wave 2), and 12 months (wave 3) following the initial assessment. Propensity score matching and multiple logistic regression were employed. Women who reported frequent crack use at wave 2 were more likely than non-drug using women to report IPV at wave 3 (odds ratio [OR]=4.4; 95% confidence interval [CI]=2.1, 9.1; P<.01), and frequent marijuana users at wave 2 were more likely than non-drug users to report IPV at wave 3 (OR=4.5; 95% CI=2.4, 8.4; P<.01). In addition, women who reported IPV at wave 2 were more likely than women who did not report IPV to indicate frequent heroin use at wave 3 (OR=2.7; 95% CI=1.1, 6.5; P=.04). Our findings suggest that the relationship between frequent drug use and IPV is bidirectional and varies by type of drug.

Objective To assess associations of intimate partner violence (IPV) with pregnancy intendedness and pre-pregnancy contraceptive use among pregnant women in South Asia. Study Design Cross-sectional analyses were conducted using most recent Demographic and Health Surveys (DHS) from Bangladesh, India and Nepal for married, pregnant women aged 15–49 years who responded to IPV assessments specific to current marriage (N=4738). Adjusted logistic and multinomial regression analyses were conducted with pooled data to assess associations of IPV ever (sexual only, physical only, sexual plus physical, none) with the outcomes of pregnancy intendedness (wanted, mistimed or unwanted) and pre-pregnancy contraceptive use (no, traditional, or modern), for the current pregnancy. Results IPV was not associated with a mistimed or unwanted pregnancy. Sexual IPV was associated with pre-pregnancy modern contraceptive use (aOR=2.32, 95% CI=1.24, 4.36); sexual plus physical IPV was associated with pre-pregnancy traditional contraceptive use (aOR=1.85, 95% CI=1.12, 3.07). Post-hoc analysis of reasons for pre-pregnancy contraceptive discontinuation revealed that women with a history of IPV, particularly sexual IPV, had higher prevalence of contraceptive failure (sexual only: 37.3%, sexual plus physical: 30.9%, physical only: 22.6%, no IPV: 13.6%). Conclusion Pregnant women who experienced sexual IPV from husbands were more likely to use contraceptives pre-pregnancy but had no reduced risk unintended pregnancy, possibly due to higher rates of pre-pregnancy contraceptive failure among those with this history. These findings suggest that victims of sexual IPV are able to acquire and use family planning services, but require more support to sustain effective contraceptive use. Implications Family planning services are reaching women affected by sexual IPV, and programs should be sensitive to this concern and the heightened vulnerability to contraceptive failure these women face. Long-acting reversible contraception could be beneficial by allowing women to have greater reproductive control in situations of compromised sexual autonomy. PMID:25769441

We describe our improved, robust, and scalable architecture by which to rapidly instrument large-scale watersheds, while providing the resulting data in real-time. Our system consists of more than twenty wireless sensor networks and thousands of sensors, which will be deployed in the American River basin (5000 sq. km) of California. The core component of our system is known as a mote, a tiny, ultra-low-power, embedded wireless computer that can be used for any number of sensing applications. Our new generation of motes is equipped with IPv6 functionality, effectively giving each sensor in the field its own unique IP address, thus permitting users to remotely interact with the devices without going through intermediary services. Thirty to fifty motes will be deployed across 1-2 square kilometer regions to form a mesh-based wireless sensor network. Redundancy of local wireless links will ensure that data will always be able to traverse the network, even if hash wintertime conditions adversely affect some network nodes. These networks will be used to develop spatial estimates of a number of hydrologic parameters, focusing especially on snowpack. Each wireless sensor network has one main network controller, which is responsible with interacting with an embedded Linux computer to relay information across higher-powered, long-range wireless links (cell modems, satellite, WiFi) to neighboring networks and remote, offsite servers. The network manager is also responsible for providing an Internet connection to each mote. Data collected by the sensors can either be read directly by remote hosts, or stored on centralized servers for future access. With 20 such networks deployed in the American River, our system will comprise an unprecedented cyber-physical architecture for measuring hydrologic parameters in large-scale basins. The spatiotemporal density and real-time nature of the data is also expected to significantly improve operational hydrology and water resource management in the basin.

To identify how nurses use the Internet through a survey performed in May 2005. A descriptive cross-sectional study was performed. The information source was a survey sent electronically and through surface mail. The study population consisted of nursing professionals from distinct autonomous regions. The overall response rate was 40% (444 of 1,100). A total of 38.6% (184) of the nursing professionals used the Internet continually, especially men and nursing staff with a high level of English. The 5 most frequent reasons for surfing the net were searching for nursing literature (63% [264]), consulting the web pages of nursing journals (58.6% [256]), seeking information on drugs (55% [230]), seeking protocol manuals (50% [204]), and consulting the web pages of colleges of nursing (48). The behavior of nursing professionals is similar to that found among the general population in the "BBVA Foundation study of the Internet in Spain". Most nursing professionals are women. Male nursing professionals more frequently search for subjects related to nursing theory. Nurses use the Internet to search for nursing literature and consult journals, protocol manuals, and colleges of nursing, as well as to be familiar with the information aimed at patients.

On March 24, 2015, the Food and Drug Administration licensed an additional combined diphtheria and tetanus toxoids and acellular pertussis adsorbed (DTaP) and inactivated poliovirus (IPV) vaccine (DTaP-IPV) (Quadracel, Sanofi Pasteur Inc.). Quadracel is the second DTaP-IPV vaccine to be licensed for use among children aged 4 through 6 years in the United States (1). Quadracel is approved for administration as a fifth dose in the DTaP series and as a fourth or fifth dose in the IPV series in children aged 4 through 6 years who have received 4 doses of DTaP-IPV-Hib (Pentacel, Sanofi Pasteur) and/or DTaP (Daptacel, Sanofi Pasteur) vaccine (2,3). This report summarizes the indications for Quadracel vaccine and provides guidance from the Advisory Committee on Immunization Practices (ACIP) for its use.

Young children living with intimate partner violence (IPV) are often also exposed to harsh parenting. Both forms of violence increase children’s risk for clinically significant disruptive behavior, which can place them on a developmental trajectory associated with serious psychological impairment later in life. Although it is hypothesized that IPV behaviors may spillover into harsh parenting, and thereby influence risk for disruptive behavior, relatively little is known about these processes in families with young children. The current study examines the overlap of the quality and frequency of psychological and physical forms of IPV and harsh parenting, and tests whether harsh parenting mediates the relationship between IPV and child disruptive behavior in a diverse cross-sectional sample of 81 children ages 4 to 6 years. Results suggest that mothers reporting a greater occurrence of psychologically aggressive IPV (e.g., yelling, name-calling) more often engage in psychological and physical aggression toward their children (odds ratios [ORs] = 4.6–9.9). Mothers reporting a greater occurrence of IPV in the form of physical assault more often engage in mild to more severe forms of physical punishment with potential harm to the child (ORs = 3.8–5.0). Psychological and physical forms of IPV and harsh parenting all significantly correlated with maternal reports of child disruptive behavior (r = .29–.40). Psychological harsh parenting partially mediated the association between psychological IPV and child disruptive behavior. However, a significant direct effect of psychological IPV on preschool children’s disruptive behavior remained. Implications for child welfare policy and practice and intervention, including the need for increased awareness of the negative impact of psychological IPV on young children, are discussed.

At least one-third of women in India experience intimate partner violence (IPV) at some point in adulthood. Our objectives were to describe the prevalence of IPV during pregnancy and after delivery in an urban slum setting, to review its social determinants, and to explore its effects on maternal and newborn health. We did a cross-sectional study nested within the data collection system for a concurrent trial. Through urban community surveillance, we identified births in 48 slum areas and interviewed mothers ~6 weeks later. After collecting information on demographic characteristics, socioeconomic indicators, and maternal and newborn care, we asked their opinions on the justifiability of IPV and on their experience of it in the last 12 months. Of 2139 respondents, 35% (748) said that violence was justifiable if a woman disrespected her in-laws or argued with her husband, failed to provide good food, housework and childcare, or went out without permission. 318 (15%, 95% CI 13, 16%) reported IPV in the year that included pregnancy and the postpartum period. Physical IPV was reported by 247 (12%, 95% CI 10, 13%), sexual IPV by 35 (2%, 95% CI 1, 2%), and emotional IPV by 167 (8%, 95% CI 7, 9). 219 (69%) women said that the likelihood of IPV was either unaffected by or increased during maternity. IPV was more likely to be reported by women from poorer families and when husbands used alcohol. Although 18% of women who had suffered physical IPV sought clinical care for their injuries, seeking help from organizations outside the family to address IPV itself was rare. Women who reported IPV were more likely to have reported illness during pregnancy and use of modern methods of family planning. They were more than twice as likely to say that there were situations in which violence was justifiable (odds ratio 2.6, 95% CI 1.7, 3.4). One in seven women suffered IPV during or shortly after pregnancy. The elements of the violent milieu are mutually reinforcing and need to be taken into account collectively in responding to both individual cases and framing public health initiatives.

Gender-specific differences in risk for intimate partner violence in South Korea.
Lee, Minjee; Stefani, Katherine M; Park, Eun-Cheol

Various risk factors of intimate partner violence (IPV) have been found to vary by gender. South Korea has one of the highest prevalences of IPV in the world; however, little is known about potential risk factors of IPV and whether gender influences this relationship. Using data from the 2006 Korea Welfare Panel Study, 8,877 married participants (4,545 men and 4,332 women) aged ≥30 years were included. Reported IPV was categorized as verbal or physical IPV and the association between IPV and related factors was assessed by multivariate logistic regression analysis. Women were significantly more likely than men were to report IPV victimization (verbal 28.2% vs. 24.4%; physical 6.9% vs. 3.4%). Wor odds of physical perpetration than women satisfied with their family. Moreover, alcohol intake was significantly associated with IPV perpetration and victimization in both genders. Significant gender-specific differences were found among factors related to perpetrating violence and being a victim of violence among adults in heterosexual relationships in South Korea.
Empowerment, PTSD and revictimization among women who have experienced intimate partner violence.
Dardis, Christina M; Dichter, Melissa E; Iverson, Katherine M

Empowerment is associated with lower posttraumatic stress disorder (PTSD) symptoms and intimate partner violence (IPV) revictimization, but the direction of these associations remains unknown. Two models were assessed: one in which empowerment is protective against future IPV revictimization and PTSD symptoms, and one in which PTSD symptoms lead to reductions in empowerment and increases in IPV revictimization. Drawn from a probability-based access survey panel of U.S. adults, the present sample included 101 women veterans who experienced past-year IPV. Baseline demographics were assessed (T0), with surveys conducted at Time 1 (T1; 18-month interim), and Time 2 (T2; 6-month interim). Cross-lagged panel models assessed the two models separately among women who reported only T1 psychological IPV victimization (58%) and women who reported T1 physical and/or sexual IPV victimization. Among psychological IPV victims, T1 empowerment was significantly associated with decreased T2 PTSD symptoms, whereas among women who reported physical and/or sexual IPV victimization, T1 empowerment was significantly associated with decreased T2 IPV revictimization. The model in which PTSD symptoms confer risk for lower empowerment was not supported; however, higher T1 PTSD symptoms were associated with increased IPV revictimization among women who reported psychological IPV only. Findings can inform interventions for IPV survivors. Copyright © 2018 Elsevier B.V. All rights reserved.

Past research has identified links between intimate partner violence (IPV) and alcohol misuse and poverty in Sri Lanka. Services that address substance misuse are amongst the few interventions shown to reduce IPV in settings similar to Sri Lanka. This paper describes the protocol for a study examining the impact of a preschool-based capacity building intervention on the prevalence of IPV and substance misuse in parents with children attending preschools, including uptake of available government services. The study is a cluster randomised controlled trial. Government-managed preschools (n = 34) in Galle and Colombo municipalities will be randomly assigned to an intervention (n = 17) or control group (n = 17). Parents with children attending these preschools will be recruited to participate. The study intervention will build the capacity of selected community volunteers (parents) and preschool teachers in the provision of information and support to families affected by IPV and substance misuse. This intervention is directed at improving uptake, access and coordination of existing services. Data will be collected from all parents, and teachers in the intervention group, pre-intervention and 10 months post-intervention. The primary outcome for this study is experience of IPV amongst mothers of preschool-attending children. Secondary outcomes are substance misuse amongst fathers, measured via the locally adapted Alcohol Use Disorders Identification Test and Drug Abuse Screening Test; and awareness and uptake of services for these issues measured through locally-relevant tools. Demographic information and satisfaction with the intervention will also be assessed. By intervening through preschools we aim to support high-risk families early enough to arrest the cycle of violence that results in children themselves becoming victims and perpetrators of such violence. The innovative project design will reach the most vulnerable sections of the community and will provide a sustainable and feasible strategy for scale-up of the intervention. This study is registered with the Sri Lankan Clinical Trials Registry (2017/038) and has been submitted to ClinicalTrials.gov (U.S National Institutes of Health) under the title "Randomized control trial: preschool-based training and support programs to reduce intimate partner violence (IPV) by addressing alcohol and drug misuse in young families in Sri Lanka"; Registration number: NCT03341455 ; Registration date: 14 November 2017.

Violence related injury is a serious public health issue all over the world. This study aims to assess the association between several socio-economic factors and intimate partner violence (IPV) in Nepal. A cross-sectional study was conducted among 236 women working in carpet and garment factories in Kathmandu, Nepal. Interviews were conducted to collect quantitative data on three forms of IPV, namely physical violence, psychological violence and sexual violence, as well as on a number of potentially associated factors. Twenty-two percent of women experienced sexual IPV, 28% physical IPV and 35% psychological IPV at least once in the last 12 months. The variables independently associated with at least one form of IPV were: age of the woman >29 years [OR = 4.23, p = 0.025 for physical IPV; OR = 6.94, p = 0.008 for sexual IPV; OR = 3.42, p = 0.043 for psychological IPV], alcohol consumption of the husband [OR = 9.97, p < 0.001 for physical IPV; OR = 3.76, p = 0.004 for sexual IPV; OR = 4.85, p < 0.001 for psychological IPV], education of the husband above primary level [OR = 0.43, p = 0.013 for physical IPV; OR = 0.51, p = 0.033 for psychological IPV], and economic dependency of the woman on the husband [OR = 3.04, p = 0.021 for physical IPV; OR = 2.97, p = 0.008 for psychological IPV]. This study identified various factors associated with IPV and showed that economic dependence of wives on their husband was among the most important ones. Thus, for the prevention of IPV against women, long term strategies aiming at livelihood and economic empowerment as well as independence of women would be suggested.

Objectives Substance use is prevalent among young men who have sex with men (YMSM) and may be associated with intimate partner violence (IPV). Experiences of IPV are associated with several adverse health conditions among adult MSM, but there is a gap in knowledge about this relationship among YMSM which warrants further investigation. Methods This study employs baseline data from a prospective cohort study to examine lifetime experiences of IPV in relation to substance use in the previous 30 days among n=528 YMSM in New York City from 2009-11. To examine the extent to which IPV (any experiences, victimization, and perpetration) are related to substance use (alcohol, marijuana, stimulant, and other drugs) in the last 30 days, distinct 2-step multinomial logistic regression models, controlling for sociodemographic differences, were constructed. Results 44.3% reported lifetime IPV experience, with 39.2% of reporting victimization and 30.5% reporting perpetration. IPV is associated with a 1.6 increased odds of 2 or more instances of alcohol use, a 1.6–1.8 increased odds of 2 or more instances of marijuana use, a 1.8–2.5 increased odds of 2 or more instances of stimulant use, and a 4.1–6.1 increased odds of 2 or more instances of other substance use. Conclusion Findings highlight the strong association between IPV and increased frequency of substance use among YMSM and provide support that violence may exist as part of a syndemic facing YMSM. Prevention and intervention strategies may be improved by addressing substance use in the context of IPV and other related health challenges. PMID:26130334

Intimate partner violence (IPV) and its associated negative mental health consequences are significant for women in New Zealand and internationally. One of the most widely recommended interventions is safety planning. However, few women experiencing violence access specialist services for safety planning. A safety decision aid, weighing the dangers of leaving or staying in an abusive relationship, gives women the opportunity to prioritise, plan and take action to increase safety for themselves and their children. This randomised controlled trial is testing the effectiveness of an innovative, interactive web-based safety decision aid. The trial is an international collaborative concurrent replication of a USA trial (IRIS study NCT01312103), regionalised for the Aotearoa New Zealand culture and offers fully automated online trial recruitment, eligibility screening and consent. In a fully automated web-based trial (isafe) 340 abused women will be randomly assigned in equal numbers to a safety decision aid intervention or usual safety planning control website. Intervention components include: (a) safety priority setting, (b) danger assessment and (c) an individually tailored safety action plan. Self-reported outcome measures are collected at baseline and 3, 6, and 12-months post-baseline. Primary outcomes are depression (measured by Center for Epidemiologic Studies Depression Scale, Revised) and IPV exposure (measured by Severity Violence Against Women Scale) at 12 months post-baseline. Secondary outcomes include PTSD, psychological abuse, decisional conflict, safety behaviors and danger in the relationship. This trial will provide much-needed information on the potential relationships among safety planning, improved mental health, reduced violence as well as decreased decisional conflict related to safety in the abusive relationship. The novel web-based safety decision aid intervention may provide a cost-effective, easily accessed safety-planning resource that can be translated into clinical and community practice by multiple health disciplines and advocates. The trial will also provide information about how women in abusive relationships safely access safety information and resources through the Internet. Finally, the trial will inform other research teams on the feasibility and acceptability of fully automated recruitment, eligibility screening, consent and retention procedures.

To understand prevalence of intimate partner violence(IPV)in heterosexual men(HM)attending HIV voluntary counseling and testing(VCT)clinics and related factors in Shanghai. All the HM attending two VCT clinics in Shanghai during March-August, 2015 were recruited to participate in a cross-sectional survey with questionnaire interview and blood test for HIV. IPV was evaluated by using the questionnaire developed by WHO Multi-Country Study on Women' s Health and Domestic Violence against Women. A total of 327 participants were recruited, their average age was 29.4 years(s∶6.1). Among them 60.2%(197/327)were aged 26-35, 57.8%(189/327)never married, 78.8%(260/327)had educational level of ≥college degree, 49.5%(162/327)were not local residents; 72.2%(236/327)had steady female partners, 72.2%(236/327)had 2 or more female partners in the past year, 6.1%(20/327)reported being diagnosed with sexually transmitted disease(STD). 1.8%(6/327)were tested to be HIV-positive. 28.4%(93/327)had IPV behaviors against heterosexual partners. Multivariate logistic regression analysis indicated that IPV behavior against heterosexual partners was significantly associated with experience of commercial sex(aOR=2.19, 95%CI: 1.16-4.15)and witness of domestic violence in early life(aOR=3.19; 95%CI: 1.58-6.45). IPV prevalence was relatively high in HM attendants in VCT clinics in Shanghai and IPV intervention is needed to conduct in VCT clinics. Multivariate regression analysis showed that the factors associated with IPV behaviors included having sex with female sex workers and the witness of domestic violence between parents. Future research is needed to further explore the association between IPV and HIV infection.

Gender inequity is a risk factor for intimate partner violence (IPV), although there is little research on this relationship that focuses on youth or males. Using survey data collected from 240 male and 198 female youth aged 15-24 in Rio de Janeiro, Brazil, we explore the association between individual-level support for gender equity and IPV experiences in the past 6 months and describe responses to and motivations for IPV. Factor analysis was used to construct gender equity scales for males and females. Logistic and multinomial logistic regression models were used to examine the relationship between gender equity and IPV. About half of female youth reported some form of recent IPV, including any victimization (32%), any perpetration (40%), and both victimization and perpetration (22%). A total of 18% of male youth reported recently perpetrating IPV. In logistic regression models, support for gender equity had a protective effect against any female IPV victimization and any male IPV perpetration and was not associated with female IPV perpetration. Female victims reported leaving the abusive partner, but later returning to him as the most frequent response to IPV. Male perpetrators said the most common response of their victims was to retaliate with violence. Jealousy was the most frequently reported motivation of females perpetrating IPV. Gender equity is an important predictor of IPV among youth. Examining the gendered context of IPV will be useful in the development of targeted interventions to promote gender equity and healthy relationships and to help reduce IPV among youth.

Rotavirus is the leading cause of severe acute gastroenteritis in infants and young children. Most children are infected with rotavirus, and the health and economic burdens of rotavirus gastroenteritis on healthcare systems and families are considerable. In 2012 pentavalent rotavirus vaccine (RV5) and diphtheria, tetanus, acellular pertussis and inactivated poliovirus vaccine derived from Sabin strains (DTaP-sIPV) were licensed in Japan. We examined the immunogenicity and safety of DTaP-sIPV when administrated concomitantly with RV5 in Japanese infants. A total of 192 infants 6 to 11 weeks of age randomized to Group 1 (N = 96) received DTaP-sIPV and RV5 concomitantly, and Group 2 (N = 96) received DTaP-sIPV and RV5 separately. Antibody titer to diphtheria toxin, pertussis antigens (PT and FHA), tetanus toxin, and poliovirus type 1, 2, and 3 were measured at 4 to 6 weeks following 3-doses of DTaP-sIPV. Seroprotection rates for all components of DTaP-sIPV were 100% in both groups, and the geometric mean titers for DTaP-sIPV in Group 1 were comparable to Group 2. Incidence of systemic AEs (including diarrhea, vomiting, fever, and nasopharyngitis) were lower in Group 1 than in Group 2. All vaccine-related AEs were mild or moderate in intensity. There were no vaccine-related serious AEs, no deaths, and no cases of intussusception during the study. Concomitant administration of DTaP-sIPV and RV5 induced satisfactory immune responses to DTaP-sIPV and acceptable safety profile. The administration of DTaP-sIPV given concomitantly with RV5 is expected to facilitate compliance with the vaccination schedule and improve vaccine coverage in Japanese infants.

Intimate Partner Violence (IPV) is a significant public health problem with negative health consequences for women and their pregnancies. While social support has a protective effect against IPV and reduces health consequences of violence, its association with experiencing IPV during pregnancy remain less explored. In our study we aimed to determine the effect of social support on IPV during pregnancy among women attending antenatal care in Moshi, Tanzania METHODS: The study was part of a prospective cohort study that assessed the impact of violence on reproductive health of 1,116 participants. Pregnant women were enrolled below 24 weeks of gestation and followed until delivery. The experiences of social support and IPV during pregnancy were assessed at the 34 th week of gestation. Logistic regression analysis was performed to assess the relationship between social support and IPV, with adjustment for potential confounders. The prevalence of IPV during pregnancy was 30.3% where the majority (29.0%) experienced repeated episodes of abuse. Regarding practical social support, having no one to help financially was associated with increased odds of IPV and repeated episodes of abuse during pregnancy, AOR 3.57, (95% CI 1.85 - 6.90) and AOR 3.21, (95% CI 1.69 - 6.11) respectively. For social support in terms of communication, talking to a member of the family of origin at least monthly was associated with decreased odds of IPV and repeated episodes of IPV during pregnancy, AOR 0.46 (95% CI 0.26 - 0.82) and AOR 0.41 (95% CI 0.23 - 0.73) respectively. Perceiving that family of origin will not offer support was associated with a increased odds of IPV and repeated episodes of IPV, AOR 2.29, (95% CI 1.31 - 3.99) and AOR 2.14, (95% CI 1.23 - 3.74) respectively. Nearly one third of women experienced IPV during pregnancy. Social support to women is associated with decreased odds of experiencing IPV during pregnancy. The family of origin plays an important role in providing social support to women who experience abuse during pregnancy; however, their true involvement in mitigating the impact of violence in the African setting needs further research.

The objectives of this study were, first, to explore the prevalence of aggressors with lifetime intimate partner violence (IPV) among patients in the Proyecto Hombre of Navarra (Spain) addiction treatment programme; and second, to know the specific and differential characteristics of patients presenting IPV as aggressors. A sample of 162 patients (119 men and 43 women) was assessed. Data on socio-demographic and substance consumption characteristics, IPV variables, psychopathological symptoms, and personality variables were obtained. The profiles of patients in addiction treatment with and without a history of violence towards their partners were compared. The results showed that 33.6% of people in treatment for addiction had committed violence against their partners. This prevalence was significantly higher (χ(2) = 15.6, p < .001) in women (63.3%) than in men (24.2%). In the 98.4% of the cases the IPV was bidirectional. Patients with a history of IPV perpetration showed greater severity in substance consumption variables, psychopathological symptoms, and personality traits. Gender, the family scale on the European version of the Addiction Severity Index (EuropASI), and the aggressive-sadistic scale on the Millon Clinical Multiaxial Inventory (MCMI-III) were the main variables related to the presence of IPV as aggressors. There was a differential profile in patients with IPV perpetration, showing more psychopathological and personality symptoms. Moreover, in this study being a woman was one of the main predictors of committing IPV. © American Academy of Addiction Psychiatry.

Intimate partner violence (IPV) is a significant public health issue that affects 1 in 3 women globally and a similarly large number of women in Nepal. Over the past decade, important policy and programmatic steps have been taken to address violence against women in Nepal. There remains a dearth of evidence on the effectiveness of primary violence prevention strategies. The Change Starts at Home study begins to fill this gap by utilizing a multi-component social behaviour change communication (SBCC) strategy involving a radio drama and community mobilization to shift attitudes, norms and behaviours that underpin IPV perpetration in Nepal. The study uses a concurrent mixed-methods design. The quantitative aspect of the evaluation is a pair-matched, repeated cross-sectional 2-armed, single-blinded cluster trial (RCT: N = 36 clusters, 1440 individuals), comparing a social behaviour change communication (SBCC) strategy to radio programming alone for its impact on physical and / or sexual IPV at the end of programming (12 months' post-baseline) and 6-months post the cessation of project activities (18-months post baseline). The qualitative aspects of the design include several longitudinal approaches to understand the impact of the intervention and to examine mechanisms of change including in-depth interviews with participants (N = 18 couples), and focus group discussions with community leaders (N = 3 groups), and family members of participants (N = 12 groups). Treatment effects will be estimated with generalized logistic mixed models specified to compare differences in primary outcome from baseline to 12-month follow-up, and baseline to 18-months follow-up in accordance with intention-to-treat principles. The study rigorously evaluates the effectiveness of a promising strategy to prevent IPV. The results of the trial will be immediately useful for governmental, nongovernmental, and donor funded programs targeting partner violence or social norms that underpin it. Findings of the study will also contribute to global knowledge on the effectiveness of media and community engagement as a primary prevention strategy for IPV.

Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration. This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health. We used logistic regression to examine the associations of financial stressors and each type of IPV (minor, severe, causing injury), and multinomial logit regression to examine the associations of financial stressors and patterns of co-occurring types of IPV perpetration (only minor; only severe; minor and severe; minor, severe, and causing injury; compared with no perpetration). Fewer men perpetrated threats/minor physical IPV (6.7 %) or severe physical IPV (3.4 %) compared with women (11.4 % and 8.8 %, respectively). However, among physical IPV perpetrators, a higher percentage of men (32.0 %) than women (21.0 %) reported their partner was injured as a result of the IPV. In logistic regression models of each type of IPV perpetration, both the number of stressors experienced and several types of financial stressors were associated with perpetrating each type of IPV. Utilities nonpayment, housing nonpayment, food insecurity, and no phone service were associated with increased odds of perpetrating each form of IPV in adjusted analysis. Eviction was associated with perpetrating severe physical IPV but not threats/minor IPV or IPV causing injury. In multinomial logit regression comparing patterns of IPV perpetration to perpetrating no physical IPV, the relationships of financial stressors were less consistent. Food insecurity was associated with perpetrating only minor physical IPV. Comparatively, overall number of financial stressors and four types of financial stressors (utilities nonpayment, housing nonpayment, food insecurity, and disconnected phone service) were associated with perpetrating all three forms of physical IPV. Combined with prior research, our results suggested interventions to improve financial well-being may be a novel way to reduce physical IPV perpetration.

Interactive browsing of 3D environment over the Internet

In this paper, we describe a system for wandering in a realistic environment over the Internet. The environment is captured by the concentric mosaic, compressed via the reference block coder (RBC), and accessed and delivered over the Internet through the virtual media (Vmedia) access protocol. Capturing the environment through the concentric mosaic is easy. We mount a camera at the end of a level beam, and shoot images as the beam rotates. The huge dataset of the concentric mosaic is then compressed through the RBC, which is specifically designed for both high compression efficiency and just-in-time (JIT) rendering. Through the JIT rendering function, only a portion of the RBC bitstream is accessed, decoded and rendered for each virtual view. A multimedia communication protocol -- the Vmedia protocol, is then proposed to deliver the compressed concentric mosaic data over the Internet. Only the bitstream segments corresponding to the current view are streamed over the Internet. Moreover, the delivered bitstream segments are managed by a local Vmedia cache so that frequently used bitstream segments need not be streamed over the Internet repeatedly, and the Vmedia is able to handle a RBC bitstream larger than its memory capacity. A Vmedia concentric mosaic interactive browser is developed where the user can freely wander in a realistic environment, e.g., rotate around, walk forward/backward and sidestep, even under a tight bandwidth of 33.6 kbps.

The IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) was proposed for various applications of IPv6 low power wireless networks. While RPL supports various routing metrics and is designed to be suitable for wireless sensor network environments, it does not consider the mobility of nodes. Therefore, there is a need for a method that is energy efficient and that provides stable and reliable data transmission by considering the mobility of nodes in RPL networks. This paper proposes an algorithm to support node mobility in RPL in an energy-efficient manner and describes its operating principle based on different scenarios. The proposed algorithm supports the mobility of nodes by dynamically adjusting the transmission interval of the messages that request the route based on the speed and direction of the motion of mobile nodes, as well as the costs between neighboring nodes. The performance of the proposed algorithm and previous algorithms for supporting node mobility were examined experimentally. From the experiment, it was observed that the proposed algorithm requires fewer messages per unit time for selecting a new parent node following the movement of a mobile node. Since fewer messages are used to select a parent node, the energy consumption is also less than that of previous algorithms.

Intimate partner violence (IPV) is a global health issue affecting mainly women and is known to escalate during pregnancy and impact negatively on obstetric and perinatal outcomes. The aim of this study is to determine the incidence of IPV in a pregnant multicultural population and to determine the relationship between IPV reported at booking interview and maternal and perinatal outcomes. This is a retrospective population-based data study. We analysed routinely collected data (2006-2016) from the ObstetriX system on a cohort of pregnant women. 33 542 women giving birth in a major health facility in Western Sydney. Incidence of IPV, association with IPV and other psychosocial variables and maternal and perinatal outcomes. 4.3% of pregnant women reported a history of IPV when asked during the routine psychosocial assessment. Fifty-four per cent were not born in Australia, and this had increased significantly over the decade. Women born in New Zealand (7.2%) and Sudan (9.1%) were most likely to report IPV at the antenatal booking visit, with women from China and India least likely to report IPV. Women who reported IPV were more likely to report additional psychosocial concerns including Edinburgh Postnatal Depression Scale scores > 13 (7.6%), thoughts of self-harm (2.4%), childhood abuse (23.6%), and a history of anxiety and depression (34.2%). Women who reported IPV were more likely to be Australian born, smoke and be multiparous and to have been admitted for threatened preterm labour (Adjusted Odds Ratio (AOR) 1.8, 95% CI 1.28 to 2.39). A report of IPV at the first antenatal booking visit is associated with a higher level of reporting on all psychosocial risks, higher antenatal admissions, especially for threatened preterm labour. More research is needed regarding the effectiveness of current IPV screening for women from other countries. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Research on intimate partner violence (IPV) has evolved over the last decade with increasing interest in how IPV develops over adolescence and young adulthood. Studies examining patterns of IPV over time have generally focused on victimization with less attention to temporal shifts in perpetration. While it is generally assumed that IPV peaks during young adulthood, this has not been empirically verified and documented. Additionally, prior longitudinal analyses of IPV have focused on identifying trajectories and their accompanying risk factors, with less attention given to within-individual change in IPV experiences across and within relationships. Drawing on five waves of data from the Toledo Adolescent Relationships Study (TARS), we examined patterns of the perpetration of IPV among a diverse sample of adolescents and young adults (51.1% female, 63.9% non-Hispanic White, 24.6% non-Hispanic Black, 11.5% Hispanic) spanning the ages of 13–28 years (N = 1,164). Analyses demonstrated that IPV patterns deviate from the age-crime curve, with women’s involvement in IPV increasing, while their involvement in other antisocial behaviors is decreasing. Traditional behavioral and psychological risk factors (delinquency, alcohol and drug use, depressive symptoms) accounted for some of the age variation in IPV for men, but these factors did not account for age variation in IPV among women. Relationship risk factors including frequency of disagreements, trust, jealousy, validation and self-disclosure, however, accounted for substantial portions of the age-IPV perpetration relationship for male and female youth. These findings reinforce recent calls for prevention efforts that focus on the development and maintenance of healthy relationships. PMID:25081024

Virtual router enables the coexistence of different networks on the same physical facility and has lately attracted a great deal of attention from researchers. As the number of IPv6 addresses is rapidly increasing in virtual routers, designing an efficient IPv6 routing lookup algorithm is of great importance. In this paper, we present an IPv6 lookup algorithm called weight-balanced tree (WBT). WBT merges Forwarding Information Bases (FIBs) of virtual routers into one spanning tree, and compresses the space cost. WBT's average time complexity and the worst case time complexity of lookup and update process are both O(logN) and space complexity is O(cN) where N is the size of routing table and c is a constant. Experiments show that WBT helps reduce more than 80% Static Random Access Memory (SRAM) cost in comparison to those separation schemes. WBT also achieves the least average search depth comparing with other homogeneous algorithms.
Beyond passivity: Dependency as a risk factor for intimate partner violence.
Kane, Fallon A; Bornstein, Robert F
2016-02-01
Interpersonal dependency in male perpetrators of intimate partner violence (IPV) is an understudied phenomenon but one that has noteworthy clinical implications. The present investigation used meta-analytic techniques to quantify the dependency-IPV link in all extant studies examining this relationship (n of studies = 17). Studies were gathered via an extensive literature search using relevant dependency/IPV search terms in the PsychInfo, Medline and Google Scholar databases. Results revealed a small but statistically significant relationship between dependency and perpetration of IPV in men (r = 0.150, Combined Z = 4.25, p < 0.0001), with the magnitude of the dependency-IPV link becoming stronger (r = 0.365, Combined Z = 6.00, p < 0.0001) when studies using measures of dependent personality disorder symptoms were omitted. Other moderators of the dependency-IPV effect size included IPV measure, type of sample and perpetrator age. These findings illuminate the underlying dynamics and interpersonal processes involved in some instances of IPV and may aid in understanding how to identify and treat male perpetrators of domestic violence.

Gender inequality and violence against women in Spain, 2006-2014: towards a civilized society.
Redding, Erika M; Ruiz-Cantero, María Teresa; Fernández-Sáez, José; Guijarro-Garvi, Marta
Considering both the economic crisis of 2008 and the Gender Equality Law (2007), this study analyses the association between gender inequality in Spanish Autonomous Communities (AC) and intimate partner violence (IPV) from 2006 to 2014 in terms of socio-demographic characteristics. Ecological study in the 17 Spanish AC on the correlation between the reported cases by IPV and deaths and the Gender Inequality Index and its dimensions: empowerment, participation in the labour market and adolescent birth rates; and their correlation with Young People Not in Education, Employment or Training (NEET). In 2006, IPV mortality rates were higher in autonomous communities with greater gender inequality than AC with more equality (4.1 vs. 2.5×10 6 women >14 years), as were reporting rates of IPV (OR=1.49; 95% CI: 1.47-1.50). In 2014, the IPV mortality rates in AC with greater gender inequality fell to just below the mortality rates in AC with more gender equality (2.5 vs. 2.7×10 6 women >14 years). Rates of IPV reports also decreased (OR=1.22; 95% CI: 1.20-1.23). Adolescent birth rates were most associated with IPV reports, which were also associated with the burden of NEET by AC (ρ 2006 =0.494, ρ 2014 =0.615). Gender-sensitive policies may serve as a platform for reduced mortality and reports of IPV in Spain, particularly in AC with more gender inequality. A reduction of NEET may reduce adolescent birth rates and in turn IPV rates. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

Intimate partner violence (IPV) has been associated with greater vulnerability to HIV infection among women. We examined prevalence and correlates of IPV among female sex workers (FSWs) in Tijuana and Ciudad Juarez, two large Mexico-U.S. border cities where HIV prevalence is rising. Participants were 300 FSWs with a current spouse or a steady partner. Participants' mean age was 33 years, and mean number of years as a sex worker was 6 years. The prevalence of IPV in the past 6 months among participants was 35%. Using multivariate logistic regression, factors independently associated with IPV included having experienced abuse as a child, a partner who had sex with someone else, and lower sexual relationship power. Our findings suggest the need for previous abuse screening and violence prevention services for FSWs in the Mexico-U.S. border region. Careful consideration of relationship dynamics such as infidelity and relationship power is warranted when assessing for IPV risk.

Participants were 300 FSWs with a current spouse or a steady partner. Participants’ mean age was 33 years, and mean number of years as a sex worker was 6 years. The prevalence of IPV in the past 6 months among participants was 35%. Using multivariate logistic regression, factors independently associated with IPV included having experienced abuse as a child, a partner who had sex with someone else, and lower sexual relationship power. Our findings suggest the need for previous abuse screening and violence prevention services for FSWs in the Mexico-U.S. border region. Careful consideration of relationship dynamics such as infidelity and relationship power is warranted when assessing for IPV risk. PMID:21532933

A community probability-sampled survey was done of 181 Chinese American women to investigate the prevalence and nature of intimate partner violence (IPV) in Chinese Americans. Of participants, 42% knew a Chinese woman who had experienced IPV. Also, 14% had experienced IPV themselves in their lifetime (8% severe and 6% minor), 3% in the previous…

To reduce the many adverse health outcomes associated with intimate partner violence (IPV), high-risk groups need to be specifically targeted in the fight against domestic violence in India. This study aims to examine the prevalence and correlates of IPV in HIV-positive and HIV-negative women from India. A convenience sample of HIV-positive and HIV-negative women responded to questionnaires to assess their experience and perception of violence. Multivariate logistic regression analysis was used to model the association between IPV and age, education, employment status, contraception use, age at first marriage, and HIV status. Although adjusting for age, education, employment status, contraception use, age at first marriage, and HIV status, women who are employed were 3.5 times more likely to suffer IPV (confidence interval [CI] = [1.5, 8.5]), women aged 18 or above at first marriage are 0.3 times less likely to face IPV (CI = [0.1, 0.6]), and women who use contraception are 7 times more likely to suffer IPV (CI = [1.4, 30.2]). Also, HIV-positive women are 3 times more likely to face sexual violence compared with HIV-negative women (CI = [1.1, 7.6]). © The Author(s) 2014.

In August 2012, the Brazilian Ministry of Health introduced inactivated polio vaccine (IPV) as part of sequential polio vaccination schedule for all infants beginning their primary vaccination series. The revised childhood immunization schedule included 2 doses of IPV at 2 and 4 months of age followed by 2 doses of oral polio vaccine (OPV) at 6 and 15 months of age. One annual national polio immunization day was maintained to provide OPV to all children aged 6 to 59 months. The decision to introduce IPV was based on preventing rare cases of vaccine-associated paralytic polio, financially sustaining IPV introduction, ensuring equitable access to IPV, and preparing for future OPV cessation following global eradication. Introducing IPV during a national multivaccination campaign led to rapid uptake, despite challenges with local vaccine supply due to high wastage rates. Continuous monitoring is required to achieve high coverage with the sequential polio vaccine schedule.

The hypothesis that the disinhibitory effects induced by alcohol consumption contribute to domestic violence has gained support from meta-analyses of mainly cross-sectional studies that examined the association between alcohol abuse and perpetration of intimate partner violence (IPV). However, findings from multilevel analyses of longitudinal data investigating the time-varying effects of heavy episodic drinking (HED) on physical IPV have been equivocal. This 12-year prospective study used multilevel analysis to examine the effects of HED and illicit drug use on perpetration of both physical and psychological IPV during early adulthood. Participants were 157 romantic couples who were assessed biennially 2 to 6 times for substance misuse and IPV. The analyses found no significant main effect of either HED or drug use on perpetration of IPV but there were significant interactions of both HED and drug use with age. Moreover, the developmental trends in substance use effects on IPV typically varied by gender and type of IPV. PMID:25678737

AEGIS: A Lightweight Firewall for Wireless Sensor Networks
NASA Astrophysics Data System (ADS)
Hossain, Mohammad Sajjad; Raghunathan, Vijay
Firewalls are an essential component in today's networked computing systems (desktops, laptops, and servers) and provide effective protection against a variety of over-the-network security attacks. With the development of technologies such as IPv6 and 6LoWPAN that pave the way for Internet-connected embedded systems and sensor networks, these devices will soon be subject to (and need to be defended against) similar security threats. As a first step, this paper presents Aegis, a lightweight, rule-based firewall for networked embedded systems such as wireless sensor networks. Aegis is based on a semantically rich, yet simple, rule definition language. In addition, Aegis is highly efficient during operation, runs in a transparent manner from running applications, and is easy to maintain. Experimental results obtained using real sensor nodes and cycle-accurate simulations demonstrate that Aegis successfully performs gatekeeping of a sensor node's communication traffic in a flexible manner with minimal overheads.

Intimate partner violence (IPV) remains a serious problem with a wide range of health consequences including poor maternal and newborn health outcomes. We assessed the relationship between IPV, forced first sex (FFS) and maternal and newborn health outcomes. A cross sectional study was conducted with 2042 women aged 15-49 years attending postnatal care at six clinics in Harare, Zimbabwe, 2011. Women were interviewed on IPV while maternal and newborn health data were abstracted from clinic records. We conducted logistic regression models to assess the relationship between forced first sex (FFS), IPV (lifetime, in the last 12 months and during pregnancy) and maternal and newborn health outcomes. Of the recent pregnancies 27.6% were not planned, 50.9% booked (registered for antenatal care) late and 5.6% never booked. A history of miscarriage was reported by 11.5%, and newborn death by 9.4% of the 2042 women while 8.6% of recent livebirths were low birth weight (LBW) babies. High prevalence of emotional (63,9%, 40.3%, 43.8%), physical (37.3%, 21.3%, 15.8%) and sexual (51.7%, 35.6%, 38.8%) IPV ever, 12 months before and during pregnancy were reported respectively. 15.7% reported forced first sex (FFS). Each form of lifetime IPV (emotional, physical, sexual, physical/sexual) was associated with a history of miscarrying (aOR ranges: 1.26-1.38), newborn death (aOR ranges: 1.13-2.05), and any negative maternal and newborn health outcome in their lifetime (aOR ranges: 1.32-1.55). FFS was associated with a history of a negative outcome (newborn death, miscarriage, stillbirth) (aOR1.45 95%CI: 1.06-1.98). IPV in the last 12 months before pregnancy was associated with unplanned pregnancy (aOR ranges 1.31-2.02) and booking late for antenatal care. Sexual IPV (aOR 2.09 CI1.31-3.34) and sexual/physical IPV (aOR2.13, 95%CI: 1.32-3.42) were associated with never booking for antenatal care. Only emotional IPV during pregnancy was associated with low birth weight (aOR1.78 95%CI1.26-2.52) in the recent pregnancy and any recent pregnancy negative outcomes including LBW, premature baby, emergency caesarean section (aOR1.38,95%CI:1.03-1.83). Forced first sex (FFS) and intimate partner violence (IPV) are associated with adverse maternal and newborn health outcomes. Strengthening primary and secondary violence prevention is required to improve pregnancy-related outcomes.

To investigate the prescription of potentially addictive drugs, including analgesics and central nervous system depressants, to women who had experienced intimate partner violence (IPV). Prospective population-based cohort study. Information about IPV from the Oslo Health Study 2000/2001 was linked with prescription data from the Norwegian Prescription Database from 1 January 2004 through 31 December 2009. The study included 6081 women aged 30-60 years. Prescription rate ratios (RRs) for potentially addictive drugs derived from negative binomial models, adjusted for age, education, paid employment, marital status, chronic musculoskeletal pain, mental distress and sleep problems. Altogether 819 (13.5%) of 6081 women reported ever experiencing IPV: 454 (7.5%) comprised physical and/or sexual IPV and 365 (6.0%) psychological IPV alone. Prescription rates for potentially addictive drugs were clearly higher among women who had experienced IPV: crude RRs were 3.57 (95% CI 2.89 to 4.40) for physical/sexual IPV and 2.13 (95% CI 1.69 to 2.69) for psychological IPV alone. After full adjustment RRs were 1.83 (1.50 to 2.22) for physical/sexual IPV, and 1.97 (1.59 to 2.45) for psychological IPV alone. Prescription rates were increased both for potentially addictive analgesics and central nervous system depressants. Furthermore, women who reported IPV were more likely to receive potentially addictive drugs from multiple physicians. Women who had experienced IPV, including psychological violence alone, more often received prescriptions for potentially addictive drugs. Researchers and clinicians should address the possible adverse health and psychosocial impact of such prescription and focus on developing evidence-based healthcare for women who have experienced IPV.

To describe the relationship between exposure to physical and/or sexual intimate partner violence (IPV) and indicators of antenatal care (ANC) service utilization among Honduran women of reproductive age. Data from the 2011-2012 Honduras Demographic and Health Survey were analyzed to describe the relationship between self-reported exposure to IPV and two ANC outcomes: (1) sufficient ANC visits (defined by the Honduran Ministry of Health as five or more visits) and (2) early ANC initiation (within the first trimester). Multiple logistic regression was used to estimate effects of physical and sexual IPV on the outcomes, controlling for women's age, education, literacy, residence, household size, religion, parity, wealth, husband's age, and husband's education. Of women who were married, had at least one living child 5 years or younger, and completed the IPV module (N = 6 629), 13.5% of them reported any physical IPV, and 4.1% reported both physical and sexual IPV. There was no significant association between IPV and early ANC; however, a significant relationship between IPV and sufficient ANC was found. Women who experienced any physical IPV (adjusted odds ratios (aOR) = 1.25; 95% confidence interval (CI): 1.00-1.56) or sexual IPV (aOR = 1.53; 95% CI: 1.08-2.16) were, respectively, 25% and 53% more likely to receive insufficient ANC. Honduras has one of highest rates of interpersonal violence of any nation in the world. In Honduras, IPV is a contributor to this broader category of interpersonal violence as well as a risk factor for insufficient ANC. Our findings suggest that universal IPV screening during ANC as well as future initiatives aimed at reducing IPV might improve ANC utilization in the country.

The polio eradication endgame strategic plan calls for the sequential removal of Sabin poliovirus serotypes from the trivalent oral poliovirus vaccine (tOPV), starting with type 2, and the introduction of ≥1 dose of inactivated poliovirus vaccine (IPV), to maintain an immunity base against poliovirus type 2. The global removal of oral poliovirus type 2 was successfully implemented in May 2016. However, IPV supply constraints has prevented introduction in 21 countries and led to complete stock-out in >20 countries. We conducted a literature review and contacted corresponding authors of recent studies with fractional-dose IPV (fIPV), one-fifth of intramuscular dose administered intradermally, to conduct additional type 2 immunogenicity analyses of two fIPV doses compared with one full-dose IPV. Four studies were identified that assessed immunogenicity of two fIPV doses compared to one full-dose IPV. Two fractional doses are more immunogenic than 1 full-dose, with type 2 seroconversion rates improving between absolute 19-42% (median: 37%, p<0.001) and relative increase of 53-125% (median: 82%), and antibody titer to type 2 increasing by 2-32-fold (median: 10-fold). Early age of administration and shorter intervals between doses were associated with lower immunogenicity. Overall, two fIPV doses are more immunogenic than a single full-dose, associated with significantly increased seroconversion rates and antibody titers. Two fIPV doses together use two-fifth of the vaccine compared to one full-dose IPV. In response to the current IPV shortage, a schedule of two fIPV doses at ages 6 and 14weekshas been endorsed by technical oversight committees and has been introduced in some affected countries.

HIV assisted partner services (APS) are a notification and testing strategy for sex partners of HIV-infected index patients. This cluster-randomized controlled trial secondary data analysis investigated whether history of intimate partner violence (IPV) modified APS effectiveness and risk of relationship dissolution. Eighteen HIV testing and counseling sites in Kenya randomized to provide immediate APS (intervention) or APS delayed for 6 weeks (control). History of IPV was ascertained at study enrollment and defined as reporting ever experiencing physical or sexual IPV. Those reporting IPV in the month before enrollment were excluded. We tested whether history of IPV modified intervention effectiveness and risk of relationship dissolution using population-averaged Poisson and log-binomial generalized estimating equation models. Exploratory analyses investigated associations between history of IPV and events that occurred after HIV diagnosis using log-binomial generalized estimating equation models. The study enrolled 1119 index participants and 1286 partners. Among index participants, 81 (7%) had history of IPV. History of IPV did not modify APS effectiveness in testing, newly diagnosing, or linking partners to care. History of IPV did not modify the association between receiving immediate APS and relationship dissolution during the study. Among participants who had not experienced IPV in the last month but had experienced IPV in their lifetimes, our results suggest that APS is an effective and safe partner notification strategy in Kenya. As APS is scaled up in different contexts, these data support including those reporting past IPV and closely monitoring adverse events.

Women who inject drugs are disproportionately affected by HIV and intimate partner violence (IPV); however, the link between IPV and HIV remains under-researched among substance-using women in low- and middle-income countries. This study examined associations and additive effects of different forms of IPV victimization (psychological, physical and/or injurious, and sexual) on HIV sexual risk behavior among women who inject drugs in Indonesia. Respondent-driven sampling (RDS) was used to recruit 731 women from Greater Jakarta and Bandung, West Java. RDS-II weighted prevalence of any past-year IPV was 68.9% (95% CI 65.0, 72.6) in Jakarta and 55.9% (95% CI 48.0, 63.5) in Bandung. In separate logistic regressions controlling for socio-demographic covariates, all three forms of IPV showed statistically significant associations with sexual risk behavior. After adjusting for all IPV types, psychological (OR 1.87; 95% CI 1.17, 2.99; p = 0.009) and sexual (OR 1.98; 95% CI 1.22, 3.21; p = 0.006) IPV independently predicted women's sexual risk behavior. Marginal effects models suggested that co-occurrence of multiple forms of IPV had greater adverse consequences: sexual risk behavior was reported by 64.1% of women who did not experience any IPV, but increased to 89.9% among women exposed to all three types. Comprehensive harm reduction services that integrate IPV monitoring and prevention are urgently needed to reduce both HIV and IPV.

Background Intimate partner violence (IPV) harms the health of women and their children. In Vietnam, 31% of women report lifetime exposure to physical IPV, and surprisingly, women justify physical IPV against wives more often than do men. Objective We compare men’s and women’s rates of finding good reason for wife hitting and assess whether differences in childhood experiences and resources and constraints in adulthood account for observed differences. Methods Probability samples of married men (N = 522) and women (N = 533) were surveyed in Vietnam. Ordered logit models assessed the proportional odds for women versus men of finding more “good reasons” to hit a wife (never, 1–3 situations, 4–6 situations). Results In all situations, women found good reason to hit a wife more often than did men. The unadjusted odds for women versus men of reporting more good reasons to hit a wife were 6.55 (95% CI 4.82 – 8.91). This gap disappeared in adjusted models that included significant interactions of gender with age, number of children ever born, and experience of physical IPV as an adult. Discussion Having children was associated with justifying wife hitting among women but not men. Exposure to IPV in adulthood was associated with justifying wife hitting among men but was negatively associated with justification of IPV among women. Further study of the gendered effects of resources and constraints in adulthood on attitudes about IPV against women will clarify women’s more frequent reporting than men’s that IPV against women is justified.

Intimate partner violence (IPV) against women is a serious public health issue and is associated with significant adverse health outcomes. The current study was undertaken to: 1) explore physicians' and nurses' experiences, both professional and personal, when asking about IPV; 2) determine the variations by discipline; and 3) identify implications for practice, workplace policy and curriculum development. Physicians and nurses working in Ontario, Canada were randomly selected from recognized discipline-specific professional directories to complete a 43-item mailed survey about IPV, which included two open-ended questions about barriers and facilitators to asking about IPV. Text from the open-ended questions was transcribed and analyzed using inductive content analysis. In addition, frequencies were calculated for commonly described categories and the Fisher's Exact Test was performed to determine statistical significance when examining nurse/physician differences. Of the 931 respondents who completed the survey, 769 (527 nurses, 238 physicians, four whose discipline was not stated) provided written responses to the open-ended questions. Overall, the top barriers to asking about IPV were lack of time, behaviours attributed to women living with abuse, lack of training, language/cultural practices and partner presence. The most frequently reported facilitators were training, community resources and professional tools/protocols/policies. The need for additional training was a concern described by both groups, yet more so by nurses. There were statistically significant differences between nurses and physicians regarding both barriers and facilitators, most likely related to differences in role expectations and work environments. This research provides new insights into the complexities of IPV inquiry and the inter-relationships among barriers and facilitators faced by physicians and nurses. The experiences of these nurses and physicians suggest that more supports (e.g., supportive work environments, training, mentors, consultations, community resources, etc.) are needed by practitioners. These findings reflect the results of previous research yet offer perspectives on why barriers persist. Multifaceted and intersectoral approaches that address individual, interpersonal, workplace and systemic issues faced by nurses and physicians when inquiring about IPV are required. Comprehensive frameworks are needed to further explore the many issues associated with IPV inquiry and the interplay across these issues.

HNP renumbering support in PMIPv6

Yan, Zhiwei; Geng, Guanggang; Lee, Xiaodong
2015-12-01
In the basic PMIPv6 (Proxy Mobile IPv6), the MN (Mobile Node) is assigned with a 64-bit HNP (Home Network Prefix) during the initial attachment for the HoA (Home Address) configuration. During the movements of MN, this prefix is assumed to be unchanged and then the upper layer applications do not have to use the reconfigured HoA and then the handover is transparent at the IP and above layers. However, the current protocol does not specify the related operation to support the MN to timely receive the new HNP and configure the new HoA when its HNP is renumbered. In this paper, this problem is discussed and a possible solution is proposed based on some simple extensions of the basic PMIPv6. Our analysis demonstrates that the proposed scheme can effectively discover the HNP renumbering and keep lower signaling cost, compared with the basic PMIPv6.

Gender-based violence against women, including intimate partner violence (IPV), is a pervasive health and human rights concern. However, relatively little intervention research has been conducted on how to reduce IPV in settings impacted by conflict. The current study reports on the evaluation of the incremental impact of adding "gender dialogue groups" to an economic empowerment group savings program on levels of IPV. This study took place in north and northwestern rural Côte d'Ivoire. Between 2010 and 2012, we conducted a two-armed, non-blinded randomized-controlled trial (RCT) comparing group savings only (control) to "gender dialogue groups" added to group savings (treatment). The gender dialogue group consisted of eight sessions that targeted women and their male partner. Eligible Ivorian women (18+ years, no prior experience with group savings) were invited to participate. 934 out of 981 (95.2%) partnered women completed baseline and endline data collection. The primary trial outcome measure was an overall measure of past-year physical and/or sexual IPV. Past year physical IPV, sexual IPV, and economic abuse were also separately assessed, as were attitudes towards justification of wife beating and a woman's ability to refuse sex with her husband. Intent to treat analyses revealed that compared to groups savings alone, the addition of gender dialogue groups resulted in a slightly lower odds of reporting past year physical and/or sexual IPV (OR: 0.92; 95% CI: 0.58, 1.47; not statistically significant). Reductions in reporting of physical IPV and sexual IPV were also observed (not statistically significant). Women in the treatment group were significantly less likely to report economic abuse than control group counterparts (OR = 0.39; 95% CI: 0.25, 0.60, p < .0001). Acceptance of wife beating was significantly reduced among the treatment group (β = -0.97; 95% CI: -1.67, -0.28, p = 0.006), while attitudes towards refusal of sex did not significantly change Per protocol analysis suggests that compared to control women, treatment women attending more than 75% of intervention sessions with their male partner were less likely to report physical IPV (a OR: 0.45; 95% CI: 0.21, 0.94; p = .04) and report fewer justifications for wife beating (adjusted β = -1.14; 95% CI: -2.01, -0.28, p = 0.01) ; and both low and high adherent women reported significantly decreased economic abuse (a OR: 0.31; 95% CI: 0.18, 0.52, p < 0.0001; a OR: 0.47; 95% CI: 0.27, 0.81, p = 01, respectively). No significant reductions were observed for physical and/or sexual IPV, or sexual IPV alone. Results from this pilot RCT suggest the importance of addressing household gender inequities alongside economic programming, because this type of combined intervention has potential to reduce levels of IPV. Additional large-scale intervention research is needed to replicate these findings. NCT01629472.

Hexavalent diphtheria-tetanus-acellular pertussis-inactivated poliovirus-hepatitis B-Haemophilus influenzae type b (DTaP-IPV-HB-PRP-T)-containing vaccines are increasingly the standard of care. This study evaluated the primary series (NCT01177722) and booster (NCT01444781) of a fully liquid DTaP-IPV-HB-PRP-T vaccine in Latin America. Infants (N = 1375) received hepatitis B vaccine at birth and were randomized to one of 3 batches of the investigational DTaP-IPV-HB-PRP-T or licensed control vaccine (DTaP-HB-IPV//PRP-T) at 2-4 to 6 months of age, coadministered with 7-valent pneumococcal conjugate vaccine (PCV7) (2-4-6 months) and rotavirus vaccine (2-4 months). A booster of either DTaP-IPV-HB-PRP-T or control was given at 12-24 months, coadministered with PCV7. Immunogenicity was assessed by validated assays and safety from parental reports. Primary series seroprotection and vaccine response rates were equivalent for DTaP-IPV-HB-PRP-T batches. For pooled batches, noninferiority to the control vaccine was demonstrated for each antigen. There were no descriptive differences in antibody persistence or booster response between DTaP-IPV-HB-PRP-T and the control. The booster responses to either vaccine following DTaP-IPV-HB-PRP-T primary series or to DTaP-IPV-HB-PRP-T following a control vaccine primary series were similar. The anti-aP component (filamentous hemagglutinin [FHA] and pertussis toxin [PT]) vaccine response and anti-Haemophilus influenzae type b (PRP) series seroprotection (≥0.15 µg/mL) rates were ≥73.0% after 2 primary series doses. Antipyretics had no effect on the immune response, and an extra (oral) polio vaccination had no effect on the antipolio booster response. Responses to PCV7 and rotavirus vaccine were similar for each coadministration. There were no safety concerns observed with any vaccine. These results confirm the suitability of the fully liquid DTaP-IPV-HB-PRP-T vaccine for primary and booster vaccination of infants.

The combination DTaP-IPV/Hib vaccine was licensed in the United States in 2008 for children ages 6weeks through 4years with doses administered at 2, 4, 6, and 15-18months of age. The aim of this study was to assess the safety of DTaP-IPV/Hib vaccine routinely administered as part of clinical care to infants at Kaiser Permanente Northern California. This was an observational, retrospective study that included all 2-month-old infants vaccinated with either DTaP-IPV/Hib or another DTaP-containing vaccine. We monitored all subjects for non-elective hospitalizations, emergency department visits and selected outpatient outcomes (seizures, Guillain-Barré Syndrome, encephalopathy, encephalitis, alteration of consciousness, meningitis, hypersensitivity reactions, immune thrombocytopenic purpura, hemolytic anemia, type 1 diabetes, and Kawasaki disease) beginning with their first dose through 6months after a 4th dose or until 24months of age. We calculated incidence rate ratios (IRRs) in the primary analysis by comparing rates of outcomes during the post-vaccination risk interval with rates during a comparison interval more remote from vaccination. Secondary analyses compared outcomes after DTaP-IPV/Hib with those after other DTaP-containing vaccines. We reviewed the medical records of selected outcomes. From October 1, 2008 through July 31, 2010, 14,042 subjects received a first dose of DTaP-IPV/Hib, 13,194 received 2 doses, 12,548 received 3 doses and 6702 received 4 doses. Overall, there were 166 comparisons with significantly elevated IRRs and 165 comparisons with significantly reduced IRRs. Medical record review of outcomes with significantly elevated IRRs in both the primary and secondary analyses did not suggest any relationship with DTaP-IPV/Hib. This study did not detect any safety concerns following DTaP-IPV/Hib and provides reassurance that DTaP-IPV/Hib administered as part of routine care was not associated with unexpected safety risks.

Introduction Intimate partner violence (IPV) is a public health problem that affects millions of women worldwide. The role of violence as an underlying factor in poor birth outcomes remains an area where strong evidence is lacking. The aim of this study was to determine the association between intimate partner violence (IPV) and preterm delivery (PTB) and low birth weight (LBW). Materials and methods A prospective cohort study was conducted among 1112 pregnant women attending antenatal care in Moshi–Tanzania. The women were enrolled before 24 weeks gestation, followed-up at week 34 to determine exposure to violence during pregnancy, and after delivery to estimate gestation age at delivery and birth weight. Logistic regression analysis was performed to assess the association between exposure to IPV during pregnancy and PTB and LBW while adjusting for possible confounders. In addition, stratified analysis based on previous history of adverse pregnancy outcome was performed. Results One-third of the women experienced IPV during pregnancy, 22.3% reported emotional, 15.4% sexual and 6.3% physical violence. Women exposed to physical IPV were three times more likely to experience PTB (AOR = 2.9; CI 95%: 1.3–6.5) and LBW (AOR = 3.2; CI 95%: 1.3–7.7). Women with previous adverse pregnancy outcomes and exposure to physical IPV had a further increased risk of PTB (AOR = 4.5; CI 95%: 1.5–13.7) and LBW (AOR = 4.8; CI 95%: 1.6–14.8) compared to those without previous history of adverse outcome. Conclusion Women who are exposed to IPV during pregnancy are at increased risk of PTB and LBW. The risk is even stronger if the women additionally have suffered a previous adverse pregnancy outcome. Interventions addressing IPV are urgently needed to prevent occurrence and reoccurrence of PTB and LBW. PMID:28235031

Replacement of the trivalent oral poliovirus vaccine (tOPV) with bivalent types 1 and 3 oral poliovirus vaccine (bOPV) and global introduction of inactivated poliovirus vaccine (IPV) are major steps in the polio endgame strategy. In this study, we assessed humoral and intestinal immunity in Latin American infants after three doses of bOPV combined with zero, one, or two doses of IPV. This open-label randomised controlled multicentre trial was part of a larger study. 6-week-old full-term infants due for their first polio vaccinations, who were healthy on physical examination, with no obvious medical conditions and no known chronic medical disorders, were enrolled from four investigational sites in Colombia, Dominican Republic, Guatemala, and Panama. The infants were randomly assigned by permuted block randomisation (through the use of a computer-generated list, block size 36) to nine groups, of which five will be discussed in this report. These five groups were randomly assigned 1:1:1:1 to four permutations of schedule: groups 1 and 2 (control groups) received bOPV at 6, 10, and 14 weeks; group 3 (also a control group, which did not count as a permutation) received tOPV at 6, 10, and 14 weeks; group 4 received bOPV plus one dose of IPV at 14 weeks; and group 5 received bOPV plus two doses of IPV at 14 and 36 weeks. Infants in all groups were challenged with monovalent type 2 vaccine (mOPV2) at 18 weeks (groups 1, 3, and 4) or 40 weeks (groups 2 and 5). The primary objective was to assess the superiority of bOPV-IPV schedules over bOPV alone, as assessed by the primary endpoints of humoral immunity (neutralising antibodies-ie, seroconversion) to all three serotypes and intestinal immunity (faecal viral shedding post-challenge) to serotype 2, analysed in the per-protocol population. Serious and medically important adverse events were monitored for up to 6 months after the study vaccination. This study is registered with ClinicalTrials.gov, number NCT01831050, and has been completed. Between May 20, 2013, and Aug 15, 2013, 940 eligible infants were enrolled and randomly assigned to the five treatment groups (210 to group 1, 210 to group 2, 100 to group 3, 210 to group 4, and 210 to group 5). One infant in group 1 was not vaccinated because their parents withdrew consent after enrolment and randomisation, so 939 infants actually received the vaccinations. Three doses of bOPV or tOPV elicited type 1 and 3 seroconversion rates of at least 97·7%. Type 2 seroconversion occurred in 19 of 198 infants (9·6%, 95% CI 6·2-14·5) in the bOPV-only groups, 86 of 88 (97·7%, 92·1-99·4) in the tOPV-only group (p<0·0001 vs bOPV-only), and 156 of 194 (80·4%, 74·3-85·4) infants in the bOPV-one dose of IPV group (p<0·0001 vs bOPV-only). A further 20 of 193 (10%) infants in the latter group seroconverted 1 week after mOPV2 challenge, resulting in around 98% of infants being seropositive against type 2. After a bOPV-two IPV schedule, all 193 infants (100%, 98·0-100; p<0·0001 vs bOPV-only) seroconverted to type 2. IPV induced small but significant decreases in a composite serotype 2 viral shedding index after mOPV2 challenge. 21 serious adverse events were reported in 20 patients during the study, including two that were judged to be possibly related to the vaccines. Most of the serious adverse events (18 [86%] of 21) and 24 (80%) of the 30 important medical events reported were infections and infestations. No deaths occurred during the study. bOPV provided humoral protection similar to tOPV against polio serotypes 1 and 3. After one or two IPV doses in addition to bOPV, 80% and 100% of infants seroconverted, respectively, and the vaccination induced a degree of intestinal immunity against type 2 poliovirus.

Intimate partner violence against women in Maputo city, Mozambique
2012-01-01
Background There is limited research about IPV against women and associated factors in Sub-Saharan Africa, not least Mozambique. The objective of this study was to examine the occurrence, severity, chronicity and “predictors” of IPV against women in Maputo City (Mozambique). Methods Data were collected during a 12 month-period (consecutive cases, with each woman seen only once) from 1,442 women aged 15–49 years old seeking help for abuse by an intimate partner at the Forensic Services at the Maputo Central Hospital, Maputo City, Mozambique. Interviews were conducted by trained female interviewers, and data collected included demographics and lifestyle variables, violence (using the previously validated Revised Conflict Tactics Scale (CTS2), and control (using the Controlling Behaviour Scale Revised (CBS-R). The data were analysed using bivariate and multivariate methods. Results The overall experienced IPV during the past 12 months across severity (one or more types, minor and severe) was 70.2% (chronicity, 85.8 ± 120.9).a Severe IPV varied between 26.3-45.9% and chronicity between 3.1 ± 9.1-12.8 ± 26.9, depending on IPV type. Severity and chronicity figures were higher in psychological aggression than in the other IPV types. Further, 26.8% (chronicity, 55.3 ± 117.6) of women experienced all IPV types across severity. The experience of other composite IPV types across severity (4 combinations of 3 types of IPV) varied between 27.1-42.6% and chronicity between 35.7 ± 80.3-64.9 ± 110.9, depending on the type of combination. The combination psychological aggression, physical assault and sexual coercion had the highest figures compared with the other combinations. The multiple regressions showed that controlling behaviours, own perpetration and co-occurring victimization were more important in “explaining” the experience of IPV than other variables (e.g. abuse as a child). Conclusions In our study, controlling behaviours over/by partner, own perpetration, co-occurring victimization and childhood abuse were more important factors in “explaining” sustained IPV. More investigation into women’s IPV exposure and its “predictors” is warranted in Sub-Saharan Africa, particularly Mozambique. PMID:23241146
Does intimate partner violence impact on women's initiation and duration of breastfeeding?

Intimate Partner Violence (IPV) is prevalent among recent mothers and negatively impacts their physical and emotional health. Furthermore, the negative influence of IPV on parenting capacity and children's development is well described. However, it is unclear whether there is any relationship between IPV and method of infant feeding. Little is known about how women who are subjected to IPV make decisions about infant feeding or whether living in this context impacts on their experience of breastfeeding. With what is known about the importance of breastfeeding, particularly for vulnerable populations, research is essential to inform clinical practice and to develop appropriate community support strategies. This paper describes an analysis of data from a pragmatic cluster randomised controlled trial: Improving maternal and child health nurse care for vulnerable mothers (MOVE). The MOVE trial was conducted in the north-western suburbs of Melbourne, Australia from April 2010-April 2011 and involved 80 maternal and child health centres, 160 nurses and 2621 women who completed a survey. Intimate partner violence was measured using the Composite Abuse Scale. Ninety-six per cent (n = 2111) of participating women initiated breastfeeding, with 80% (n = 1776) and 74% (n = 1537) indicating 'any' breastfeeding at 3 and 6 months respectively. Respondents tended to be older, well-educated with a household income > $70,000 per annum compared to the general population. The characteristics of women from the IPV and non-IPV groups were similar and together were comparable to all women who gave birth in north-west Melbourne. The reported prevalence of IPV in this survey was 6.3% (n = 138), which may be an underestimate. Breastfeeding rates did not significantly differ between IPV and non-IPV groups. Our findings suggest that women who experience IPV are just as likely to breastfeed as the broader population of women. While this analysis provide's a snapshot of breastfeeding rates for this group of women, it does not capture women's experience of IPV as it relates to feeding a baby. In order to better identify infant feeding in the context of IPV, qualitative research is also necessary to investigate in a way that fully engages victims/survivors, giving them the opportunity to give voice to their experiences.

The current aim is to examine the prevalence of intimate partner violence (IPV) among Thai women residing in Sweden and its association with mental health. We also investigate the potential influence of social isolation and social capital regarding the association between IPV and mental health outcome. A public health questionnaire in Thai was distributed by post to the entire population of Thai women, aged 18-64, residing in two regions in Sweden since 2006. Items included aspects related to IPV (physical/sexual/emotional), sociodemographic background, physical health, mental health (GHQ-12), social isolation, and social capital (i.e. social trust/participation). The response rate was 62.3% (n=804). Prevalence of lifetime reported IPV was 22.1%, with 20.5% by a previous partner and 6.7% by a current partner. Previous IPV exposure was significantly related to current IPV exposure, and all IPV exposure measures were significantly related to poor mental health. However, Thai women experiencing IPV by a current partner were more at risk for poor mental health than Thai women with previous or without any experience of IPV. Also, among all women exposed to IPV, those with trust in others and without exposure to social isolation seemed to have partial protection against the adverse mental health consequences associated with IPV. Most Thai women had never been exposed to IPV, and after migrating to Sweden, women had lower IPV exposure than in Thailand. However, the increased risk for poor mental health among those Thai women exposed to IPV suggests the need for supportive measures and targeted interventions to prevent further injuries and adverse health consequences. Although poor mental health in Thai women represents an obstacle for integration, the potential resilience indicated in the group with high social trust and without exposure to social isolation suggests that such aspects be included in the program designed to facilitate integration.

Towards the Development of an Intimate Partner Violence Screening Tool for Gay and Bisexual Men

Introduction: Recent research suggests that gay and bisexual men experience intimate partner violence (IPV) at rates comparable to heterosexual women. However, current screening tools used to identify persons experiencing IPV were largely created for use with heterosexual women. Given the high prevalence of IPV among gay and bisexual men in the United States, the lack of IPV screening tools that reflect the lived realities of gay and bisexual men is problematic.This paper describes the development of a short-form IPV screening tool intended to be used with gay and bisexual men. Methods: A novel definition of IPV, informed by formative Focus Group Discussions, was derived from a quantitative survey of approximately 1,100 venue-recruited gay and bisexual men. From this new definition, a draft IPV screening tool was created. After expert review (n=13) and cognitive interviews with gay and bisexual men (n=47), a screening tool of six questions was finalized.A national, online-recruited sample (n=822) was used to compare rates of IPV identified by the novel tool and current standard tools. Results: The six-item, short-form tool created through the six-stage research process captured a significantly higher prevalence of recent experience of IPV compared to a current and commonly used screening tool (30.7% versus 7.5%, p<0.05). The novel short-form tool described additional domains of IPV not currently found in screening tools, including monitoring behaviors, controlling behaviors, and HIV-related IPV. The screener takes less than five minutes to complete and is 6th grade reading level. Conclusion: Gay and bisexual men experiencing IPV must first be identified before services can reach them. Given emergent literature that demonstrates the high prevalence of IPV among gay and bisexual men and the known adverse health sequela of experiencing IPV, this novel screening tool may allow for the quick identification of men experiencing IPV and the opportunity for referrals for the synergistic management of IPV. Future work should focus on implementing this tool in primary or acute care settings in order to determine its acceptability and its feasibility of use more broadly. PMID:23997849

As perinatal HIV-infected youth become sexually active, the potential for onward transmission becomes an increasing concern. In other populations, intimate partner violence (IPV) is a risk factor for HIV acquisition. We build on this critical work by studying the role of IPV in facilitating onward transmission among HIV-infected youth-an important step toward effective intervention. Soweto, South Africa. Self-report surveys were completed by 129 perinatal HIV-infected female youth (aged 13-24 years). We calculated the IPV prevalence and used logistic models to capture the association between IPV and health outcomes known to facilitate onward HIV transmission (eg, risky sex, poor medication adherence, depression, and substance abuse). A fifth of perinatal HIV-infected participants reported physical and/or sexual IPV in the past year; one-third reported lifetime IPV. Childhood adversity was common and positively associated with IPV. Past-year physical and/or sexual IPV was positively correlated with high-risk sex [odds ratio (OR) = 8.96; 95% confidence interval (CI): 2.78 to 28.90], pregnancy (OR = 6.56; 95% CI: 1.91 to 22.54), poor medication adherence to antiretroviral therapy (OR = 5.37; 95% CI: 1.37 to 21.08), depression (OR = 4.25; 95% CI: 1.64 to 11.00), and substance abuse (OR = 4.11; 95% CI: 1.42 to 11.86). Neither past-year nor lifetime IPV was associated with viral load or HIV status disclosure to a partner. We find that IPV may increase risk for onward HIV transmission in perinatal HIV-infected youth by both increasing engagement in risky sexual behaviors and lowering medication adherence. HIV clinics should consider integrating primary IPV prevention interventions, instituting routine IPV screening, and collocating services for victims of violence.

Objective Women who develop symptoms of posttraumatic stress disorder (PTSD) and depression subsequent to interpersonal trauma are at heightened risk for future intimate partner violence (IPV) victimization. Cognitive-behavioral therapy (CBT) is effective in reducing PTSD and depression symptoms, yet limited research has investigated the effectiveness of cognitive-behavior therapy in reducing risk for future IPV among interpersonal trauma survivors. Method This study examined the effect of CBT for PTSD and depressive symptoms on the risk of future IPV victimization in a sample of women survivors of interpersonal violence. The current sample included 150 women diagnosed with PTSD secondary to an array of interpersonal traumatic events who were participating in a randomized clinical trial of different forms of cognitive processing therapy for the treatment of PTSD. Participants were assessed at nine time points as part of the larger trial: pre-treatment, six times during treatment, post-treatment, and at 6-month follow-up. Results As hypothesized, reductions in both PTSD and depressive symptoms during treatment were associated with a decreased likelihood of IPV victimization at a 6-month follow-up even after controlling for recent IPV (i.e., IPV from a current partner within the year prior to beginning the study) and prior interpersonal traumas. Conclusions These findings highlight the importance of identifying and treating PTSD and depressive symptoms among interpersonal trauma survivors as a method for reducing risk for future IPV.

Contribution of family violence to the intergenerational transmission of externalizing behavior.
Ehrensaft, Miriam K; Cohen, Patricia
2012-08-01
Research finds that early antisocial behavior is a risk for later intimate partner violence (IPV) perpetration and victimization, and that children's exposure to their parents' IPV is a risk for subsequent behavior problems. This study tests whether intimate violence (IPV) between partners contributes independently to the intergenerational transmission of antisocial behavior, using the Children in the Community Study, a representative sample (N = 821) followed for over 25 years in 6 assessments. The present study includes a subsample of parents (N = 678) and their offspring (N = 396). We test the role of three mechanisms by which IPV may influence child antisocial behavior-parental psychopathology, parenting practices, and child self-regulation. Results suggest that IPV independently increased the risk for offspring externalizing problems, net of the effects of parental history of antisocial behavior and family violence. IPV also increased the risk for parental post traumatic stress disorder (PTSD) and alcohol use disorder 2 years later, but not for major depressive disorder. Alcohol use disorder independently increased the risk for offspring externalizing behavior, but IPV continued to predict offspring externalizing net of parental alcohol use. Parenting, particularly low satisfaction with the child, was significantly associated with both IPV and externalizing behavior, but did not mediate the effects of IPV on externalizing. IPV predicted higher levels of emotional expressivity, aggression and hostile reactivity, and depressive mood in offspring. Implications for future research and prevention are discussed.

To investigate the prevalence of intimate partner violence (IPV) against pregnant women and its relationship with adverse maternal outcomes, including preterm labour, abortion, caesarean section, antenatal hospitalization and vaginal bleeding, in the West Azerbaijan, Iran. Cross-sectional design. In total, 1300 pregnant women, aged 18-39 years, who were referred to hospitals in the Iranian cities of Miandoab and Mahabad in the province of West Azerbaijan in 2009-2010 were recruited for this study by a convenience sampling method. Participants were asked to share their experiences of IPV during pregnancy and adverse maternal outcomes. Of these pregnant women, 945 (72.8%) reported that they had experienced IPV during their last pregnancy. A significant association was found between IPV and preterm labour [adjusted odds ratio (adjOR) 1.54, 95% confidence interval (CI) 1.16-2.03], caesarean section (adjOR 11.84, 95% CI 6.37-22.02), antenatal hospitalization (adjOR 6.34, 95% CI 3.82-10.52) and vaginal bleeding (adjOR 1.51, 95% CI 0.9-2.3). This study demonstrated a high prevalence of IPV during pregnancy, and found that IPV was associated with adverse maternal outcomes including preterm labour, caesarean section, antenatal hospitalization and vaginal bleeding. This adds to the existing literature and can be used to inform healthcare practices in developing countries. Medical, health and surgical services for pregnant women should consider screening for IPV, and providers should be aware that IPV victims are at increased risk for adverse outcomes. Services should also develop links with the Battered Women's Movement; such programmes now exist in many countries. Copyright © 2013 The Royal Society for Public Health. Published by Elsevier Ltd.

We propose an Advanced Mobility Handover scheme (AMH) in this paper for seamless mobility in MIPv6-based wireless networks. In the proposed scheme, the mobile node utilizes a unique home IPv6 address developed to maintain communication with other corresponding nodes without a care-of-address during the roaming process. The IPv6 address for each MN during the first round of AMH process is uniquely identified by HA using the developed MN-ID field as a global permanent, which is identifying uniquely the IPv6 address of MN. Moreover, a temporary MN-ID is generated by access point each time an MN is associated with a particular AP and temporarily saved in a developed table inside the AP. When employing the AMH scheme, the handover process in the network layer is performed prior to its default time. That is, the mobility handover process in the network layer is tackled by a trigger developed AMH message to the next access point. Thus, a mobile node keeps communicating with the current access point while the network layer handover is executed by the next access point. The mathematical analyses and simulation results show that the proposed scheme performs better as compared with the existing approaches.

Physical intimate partner violence (IPV) and STIs, including HIV, are highly prevalent in east Africa. While we have some evidence about women's experience with physical IPV, little is known about men's experience with physical IPV, particularly in sub-Saharan Africa. Our objective was to examine, in Tanzanian male migrant plantation residents, the prevalence of, and associations among, experience and enactment of physical IPV and prevalent STI/HIV. Data from a cross-sectional survey of male plantation residents (n=158) in northern Tanzania were analysed to estimate prevalence of physical IPV experience and enactment. We assessed associations between IPV and sexual risk behaviours, and serodiagnosis of HIV, herpes simplex virus type-2 (HSV-2) and syphilis. Overall, 30% of men had experienced and/or enacted physical IPV with their main sexual partner: 19% of men had ever experienced physical IPV with their main sexual partner; 22% had enacted physical IPV with their main sexual partner. Considering overlaps in these groups, 11% of all participants reported reciprocal (both experienced and enacted) physical IPV. 9% of men were HIV seropositive, 51% were HSV-2 seropositive and 10% were syphilis seropositive-54% had at least one STI. Men who reported reciprocal physical IPV had increased odds of STI/HIV (adjusted OR (AOR) 8.85, 95% CI 1.78 to 44.6); the association retained statistical significance (AOR 14.5, 95% CI 1.4 to 147.0) with sexual risk behaviours included in the multivariate model. Men's physical IPV experience and enactment was common among these migrant plantation residents. Men reporting reciprocal physical IPV had significantly increased odds of prevalent STI/IPV, and we hypothesise that they have unstable relationships. Physical IPV is an important risk factor for STI/HIV transmission, and programmatic activities are needed to prevent both. Published by the BMJ Publishing Group Limited.

Experience of intimate partner violence (IPV) can lead to mental health conditions, including anxiety, depression, and unhealthy substance use. Women seen in the Veterans Health Administration (VHA) face high rates of both IPV and mental health morbidity. This study aimed to identify associations between recent IPV experience and mental health diagnoses among women VHA patients. We examined medical records data for 8,888 female veteran and nonveteran VHA patients across 13 VHA facilities who were screened for past-year IPV between April, 2014 and April, 2016. Compared with women who screened negative for past-year IPV (IPV-), those who screened positive (IPV+; 8.7%) were more than twice as likely to have a mental health diagnosis, adjusted odds ratio (AOR) = 2.27, 95% confidence interval (CI) [1.95, 2.64]; or more than two mental health diagnoses, AOR = 2.29, 95% CI [1.93, 2.72]). Screening IPV+ was also associated with significantly higher odds of each type of mental health morbidity (AOR range = 1.85-3.19) except psychoses. Over half (53.5%) of the women who screened IPV+ had a mental health diagnosis, compared with fewer than one-third (32.6%) of those who screened IPV-. Each subtype of IPV (psychological, physical, and sexual violence) was significantly associated with having a mental health diagnosis (AOR range = 2.25-2.37) or comorbidity (AOR range = 2.17-2.78). Associations remained when adjusting for military sexual trauma and combat trauma among the veteran subsample. These findings highlight the mental health burden associated with past-year IPV among female VHA patients and underscore the need to address psychological and sexual IPV, in addition to physical violence.

Background and objectives Intimate partner violence (IPV) around the time of pregnancy is a serious public health concern and is known to have an adverse effect on perinatal mental health. In order to craft appropriate and effective interventions, it is important to understand how the association between IPV and postpartum depression (PPD) may differ as a function of the type and timing of IPV victimization. Here we evaluate the influence of physical, sexual and psychological IPV before, during and after pregnancy on PPD. Methods Cross-sectional survey data was collected between October 2015 and January 2016 in the Chandpur District of Bangladesh from 426 new mothers, aged 15–49 years, who were in the first six months postpartum. Multivariate logistic regression models were used to estimate the association between IPV and PPD, adjusted for socio-demographic, reproductive and psychosocial confounding factors. Results Approximately 35.2% of women experienced PPD within the first six months following childbirth. Controlling for confounders, the odds of PPD was significantly greater among women who reported exposure to physical (AOR: 1.79, 95% CI [1.25, 3.43]), sexual (AOR: 2.25, 95% CI [1.14, 4.45]) or psychological (AOR: 6.92, 95% CI [1.71, 28.04]) IPV during pregnancy as opposed to those who did not. However, both before and after pregnancy, only physical IPV evidences a direct effect on PPD. Results highlight the mental health consequences of IPV for women of Bangladesh, as well as the influence of timing and type of IPV on PPD outcomes. Conclusions and implications The findings confirm that exposure to IPV significantly increases the odds of PPD. The association is particularly strong for physical IPV during all periods and psychological IPV during pregnancy. Results reinforce the need to conduct routine screening during pregnancy to identify women with a history of IPV who may at risk for PPD and to offer them necessary support. PMID:28472056

Background HIV status disclosure is a central strategy in HIV prevention and treatment but in high prevalence settings women test disproportionately and most often during pregnancy. This study reports intimate partner violence (IPV) following disclosure of HIV test results by pregnant women. Methods In this cross sectional study we interviewed 1951 postnatal women who tested positive and negative for HIV about IPV experiences following HIV test disclosure, using an adapted WHO questionnaire. Multivariate regression models assessed factors associated with IPV after disclosure and controlled for factors such as previous IPV and other known behavioural factors associated with IPV. Results Over 93% (1817) disclosed the HIV results to their partners (96.5% HIV− vs. 89.3% HIV+, p<0.0001). Overall HIV prevalence was 15.3%, (95%CI:13.7–16.9), 35.2% among non-disclosers and 14.3% among disclosers. Overall 32.8% reported IPV (40.5% HIV+; 31.5% HIV− women, p = 0.004). HIV status was associated with IPV (partially adjusted 1.43: (95%CI:1.00–2.05 as well as reporting negative reactions by male partners immediately after disclosure (adjusted OR 5.83, 95%CI:4.31–7.80). Factors associated with IPV were gender inequity, past IPV, risky sexual behaviours and living with relatives. IPV after HIV disclosure in pregnancy is high but lower than and is strongly related with IPV before pregnancy (adjusted OR 6.18, 95%CI: 3.84–9.93). Conclusion The study demonstrates the interconnectedness of IPV, HIV status and its disclosure with IPV which was a common experience post disclosure of both an HIV positive and HIV negative result. Health services must give attention to the gendered nature and consequences of HIV disclosure such as enskilling women on how to determine and respond to the risks associated with disclosure. Efforts to involve men in antenatal care must also be strengthened. PMID:25350001

Recommended infant vaccination in Korea includes DTaP-IPV and Hib vaccines administered as separate injections. In this randomized, open, controlled study we assessed the non-inferiority of immunogenicity of DTaP-IPV//Hib pentavalent combination vaccine (Pentaxim™) compared with licensed DTaP-IPV and Hib (PRP~T) vaccines. We enrolled 418 healthy Korean infants to receive either separate DTaP-IPV and Hib vaccines (n = 206) or the pentavalent DTaP-IPV//Hib (n = 208) vaccine at 2, 4, 6 months of age. Antibodies to all components were measured before the first vaccination and one month after the third, and safety was assessed after each vaccination including recording of reactions by parents. We confirmed the non-inferiority of DTaP-IPV//Hib compared with DTaP-IPV and Hib vaccines; 100% of both groups achieved seroprotection against D, T, IPV and PRP~T, and 97.5%-99.0% demonstrated seroresponses to pertussis antigens. Antibody levels were similar in both groups, except for those to the Hib component, PRP~T. In separate and combined groups geometric mean concentrations of anti-PRP~T antibodies were 23.9 and 11.0 μg/mL, respectively, but 98.3% and 97.4% had titers ≥ 1 μg/mL, indicative of long-term protection. All vaccines were well tolerated, with no vaccine-related serious adverse event. Both groups had similar safety profiles, but the combined vaccine group had fewer injection site reactions. The immunological non-inferiority and similar safety profile of DTaP-IPV//Hib vaccine to separate DTaP-IPV and Hib vaccines, with the advantage of fewer injections and injection site reactions, supports the licensure and incorporation of DTaP-IPV//Hib into the Korean national vaccination schedule (Clinical trial registry, NCT01214889).

As its name partly indicates, the Delay-Tolerant Networking (DTN) Bundle Protocol is a protocol for delay-tolerant transmission of data via communication networks. This protocol was conceived as a result of studies of how to adapt Internet protocols so that Internet-like services could be provided across interplanetary distances in support of deep-space exploration. The protocol, and software to implement the protocol, is being developed in collaboration among experts at NASA's Jet Propulsion Laboratory and other institutions. No current Internet protocols can accommodate long transmission delay times or intermittent link connectivity. The DTN Bundle Protocol represents a departure from the standard Internet assumption that a continuous path is available from a host computer to a client computer: It provides for routing of data through networks that may be disjointed and may be characterized by long transmission delays. In addition to networks that include deepspace communication links, examples of such networks include terrestrial ones within which branches are temporarily disconnected. The protocol is based partly on the definition of a message-based overlay above the transport layers of the networks on which it is hosted.

Background Gender-based violence against women, including intimate partner violence (IPV), is a pervasive health and human rights concern. However, relatively little intervention research has been conducted on how to reduce IPV in settings impacted by conflict. The current study reports on the evaluation of the incremental impact of adding “gender dialogue groups” to an economic empowerment group savings program on levels of IPV. This study took place in north and northwestern rural Côte d’Ivoire. Methods Between 2010 and 2012, we conducted a two-armed, non-blinded randomized-controlled trial (RCT) comparing group savings only (control) to “gender dialogue groups” added to group savings (treatment). The gender dialogue group consisted of eight sessions that targeted women and their male partner. Eligible Ivorian women (18+ years, no prior experience with group savings) were invited to participate. 934 out of 981 (95.2%) partnered women completed baseline and endline data collection. The primary trial outcome measure was an overall measure of past-year physical and/or sexual IPV. Past year physical IPV, sexual IPV, and economic abuse were also separately assessed, as were attitudes towards justification of wife beating and a woman’s ability to refuse sex with her husband. Results Intent to treat analyses revealed that compared to groups savings alone, the addition of gender dialogue groups resulted in a slightly lower odds of reporting past year physical and/or sexual IPV (OR: 0.92; 95% CI: 0.58, 1.47; not statistically significant). Reductions in reporting of physical IPV and sexual IPV were also observed (not statistically significant). Women in the treatment group were significantly less likely to report economic abuse than control group counterparts (OR = 0.39; 95% CI: 0.25, 0.60, p < .0001). Acceptance of wife beating was significantly reduced among the treatment group (β = -0.97; 95% CI: -1.67, -0.28, p = 0.006), while attitudes towards refusal of sex did not significantly change Per protocol analysis suggests that compared to control women, treatment women attending more than 75% of intervention sessions with their male partner were less likely to report physical IPV (a OR: 0.45; 95% CI: 0.21, 0.94; p = .04) and report fewer justifications for wife beating (adjusted β = -1.14; 95% CI: -2.01, -0.28, p = 0.01) ; and both low and high adherent women reported significantly decreased economic abuse (a OR: 0.31; 95% CI: 0.18, 0.52, p < 0.0001; a OR: 0.47; 95% CI: 0.27, 0.81, p = 01, respectively). No significant reductions were observed for physical and/or sexual IPV, or sexual IPV alone. Conclusions Results from this pilot RCT suggest the importance of addressing household gender inequities alongside economic programming, because this type of combined intervention has potential to reduce levels of IPV. Additional large-scale intervention research is needed to replicate these findings. Trial registration Registration Number: NCT01629472. PMID:24176132

Previous research has examined the association between intimate partner violence (IPV) victimization experiences and investment model variables, particularly with relation to leaving intentions. However, research only has begun to explore the impact that various dyadic patterns of IPV (i.e., unidirectional victimization, unidirectional perpetration, bidirectional violence, and non-violence) have on investment model variables. Grounded in behavioral principles, the current study used a sample of college women to assess the impact that perpetration and victimization have on investment model variables. Results indicated that 69.2% of the sample was in a relationship with no IPV. Among those who reported IPV in their relationships, 11.9% reported unidirectional perpetration, 10.6% bidirectional violence, and 7.4% unidirectional victimization. Overall, the findings suggest that women's victimization (i.e., victim only and bidirectional IPV) is associated with lower levels of satisfaction and commitment, and that women's perpetration (i.e., perpetration only and bidirectional IPV) is associated with higher levels of investment. Women in bidirectionally violent relationships reported higher quality alternatives than women in non-violent relationships. The current study emphasizes the importance of considering both IPV perpetration and IPV victimization experiences when exploring women's decisions to remain in relationships. © The Author(s) 2015.

Children in homes with intimate partner violence (IPV) are at increased risk for physical abuse. We determined the frequency and injury patterns in children who underwent child abuse consultation after IPV exposure by retrospectively analyzing the "Examination of Siblings To Recognize Abuse" cohort of children referred for physical abuse. Children were selected who presented after IPV exposure. Among 2890 children evaluated by child abuse pediatricians, 61 (2.1%) patients presented after IPV exposure. Of the 61, 11 (18.0%) were exposed to IPV, but had no direct involvement in the IPV event, 36 (59.0%) sustained inadvertent trauma during IPV, and 14 (23.0%) were directly assaulted during IPV. Thirty-six patients (59.0%) had an injury: 31 (51.0%) had cutaneous injuries and 15 (24.6%) had internal injuries including fracture(s), intracranial or intra-abdominal injury. Of the 15 patients with internal injuries, 14 (93.3%) were less than 12 months old. Among the 36 patients with injuries, 16 (44.4%) had no report of direct injury, a report of a mechanism that did not explain the identified injuries, or a report of trauma without a specific mechanism. Five (13.9%) did not have physical examination findings to suggest the extent of their internal injuries. Injuries are present in a significant proportion of children presenting to Emergency Departments after IPV exposure. History and physical examination alone are insufficient to detect internal injuries especially in infants. These preliminary results support the need for future, prospective studies of occult injury in children exposed to IPV. Copyright © 2018 Elsevier Ltd. All rights reserved.

This study sought to assess the association between traditional masculine gender role ideologies and sexual risk and intimate partner violence (IPV) perpetration behaviors in young men's heterosexual relationships. Sexually active men age 18-35 years attending an urban community health center in Boston were invited to join a study on men's sexual risk; participants (N=307) completed a brief self-administered survey on sexual risk (unprotected sex, forced unprotected sex, multiple sex partners) and IPV perpetration (physical, sexual and injury from/need for medical services due to IPV) behaviors, as well as demographics. Current analyses included men reporting sex with a main female partner in the past 3 months (n=283). Logistic regression analyses adjusted for demographics were used to assess significant associations between male gender role ideologies and the sexual risk and IPV perpetration behaviors. Participants were predominantly Hispanic (74.9%) and Black (21.9%); 55.5% were not born in the continental U.S.; 65% had been in the relationship for more than 1 year. Men reporting more traditional ideologies were significantly more likely to report unprotected vaginal sex in the past 3 months (OR(adj) = 2.3, 95% CI = 1.2-4.6) and IPV perpetration in the past year (OR(adj) = 2.1, 95% CI = 1.2-3.6). Findings indicate that masculine gender role ideologies are linked with young men's unprotected vaginal sex and IPV perpetration in relationships, suggesting that such ideologies may be a useful point of sexual risk reduction and IPV prevention intervention with this population.

The combined hexavalent diphtheria-tetanus-pertussis-hepatitis B-inactivated poliomyelitis - Haemophilus influenzae type b conjugate vaccine (Infanrix hexa™; DTPa-HBV-IPV/Hib: GlaxoSmithKline Vaccines) induces robust responses to the HBV component when administered at 3, 5 and 11-12 months of age. We assessed long term HBV antibody persistence 10-11 years after primary vaccination in infancy. Antibody persistence and immune memory were assessed post-primary vaccination at 3, 5, 11-12 months with DTPa-HBV-IPV/Hib, or monovalent HBV vaccine (Engerix™ B, GlaxoSmithKline Vaccines) co-administered with DTPa-IPV/Hib (Infanrix™-IPV/Hib, GlaxoSmithKline Vaccines) in 185 children aged 11-12 years. Blood samples were collected before and 1 month after a challenge dose of Engerix™ B (10μg dose). 10-11 years after primary vaccination the percentage of subjects with persisting anti-HBs antibody concentrations ≥10mIU/ml was 48.4% in the DTPa-HBV-IPV/Hib group and 58.4% in the DTPa-IPV/Hib+HBV group. After the HBV challenge dose, the percentage with anti-HBs ≥100mIU/ml increased from 14.7% to 93.6% in the DTPa-HBV-IPV/Hib group and 19.1% to 94.4% in the DTPa-IPV/Hib+HBV group. Anti-HBs GMCs increased by at least 187-fold in each group. An anamnestic response (≥4-fold increase in initially seropositive or anti-HBs concentration ≥10mIU/ml in initially seronegative subjects) was observed in 96.8% and 96.6% of subjects in the DTPa-HBV-IPV/Hib and DTPa-IPV/Hib+HBV groups, respectively. No serious adverse events occurred that were considered related to challenge vaccination. Administration of HBV as part of a combination vaccine or as a monovalent vaccine induced long lasting immune memory against HBV in children primed at 3, 5 and 11 months of age. Antibody persistence and immune memory were similar, suggesting that protection afforded by DTPa-HBV-IPV/Hib and monovalent HBV vaccines, is likely to be of similar duration. The administration of HBV challenge dose 10-11 years after the 3, 5, 11-12 months primary schedule induced strong anamnestic responses and was well tolerated.

Combination vaccines simplify vaccination visits and improve coverage and timeliness. DTaP5-HB-IPV-Hib is a new investigational, fully-liquid, combination vaccine designed to protect against 6 infectious diseases, including 5 pertussis antigens and OMPC instead of PT as conjugated protein for Hib component. In this multicenter, double-blind, comparator-controlled, Phase III study (NCT01480258) conducted in Sweden, Italy, and Finland, healthy infants were randomized 1:1 to receive one two immunization regimens. The DTaP5-HB-IPV-Hib Group received the investigational hexavalent vaccine (DTaP5-HB-IPV-Hib) and the Control Group received Infanrix-hexa (DTPa3-HBV-IPV/Hib) at 2, 4 and 11-12months of age. Both groups received concomitantly Prevnar 13 (PCV13) and Rotateq (RV5) or Rotarix (RV1) at 2, 4months of age and PCV13 at 11-12months. Subjects administered RV5 received a 3rd dose at 5months of age. A total of 656 subjects were randomized to the DTaP5-HB-IPV-Hib Group and 659 subjects to Control Group. Immune responses to all vaccine antigens post-toddler dose were non-inferior in the DTaP5-HB-IPV-Hib Group as compared to the Control Group. Additionally, the post-dose 2 and pre-toddler DTaP5-HB-IPV-Hib anti-PRP responses were superior. The DTaP5-HB-IPV-Hib Group responses to concomitant RV1 were non-inferior compared to the Control Group. Solicited adverse event rates after any dose were similar in both groups, except for higher rates of pyrexia (6.4% difference; 95% CI: 1.5,11.3) and somnolence (5.8% difference; 95% CI: 1.7,9.8) in the DTaP5-HB-IPV-Hib Group. Vaccine-related serious adverse events occurred infrequently in the DTaP5-HB-IPV-Hib Group (0.3%) and the Control Group (0.5%). The safety and immunogenicity of DTaP5-HB-IPV-Hib is generally comparable to Control when administered in the 2, 4, 11-12month schedule. Early Hib responses were superior versus Control. DTaP5-HB-IPV-Hib could provide a new hexavalent option for pediatric combination vaccines, aligned with recommended immunizations in Europe. V419-008 CLINICALTRIALS.GOV identifier: NCT01480258.

Extensive limb swelling (ESL) after a booster dose of acellular pertussis (aP) containing vaccine can cause concern and has the potential to be confused with cellulitis. In the United Kingdom aP-containing vaccine was introduced for primary immunisation at 2, 3 and 4months of age in 2004, with the first cohorts eligible to receive a fourth dose in 2007 at school entry. We assessed the frequency of ESL (here defined as swelling >100mms diameter) in 973 children receiving a fourth dose of one of four aP vaccines given combined with inactivated polio, tetanus and either low dose diphtheria (TdaP/IPV) or high dose diphtheria (DTaP/IPV) vaccine; 2 of the 3 DTaP/IPV vaccines also contained Haemophilus influenza b conjugate vaccine (Hib). Post-vaccination symptoms and local reactions were recorded in 7-day diaries or by a telephone follow up if no diary was returned. Local swellings >50mm diameter were reported by 2.2% TdaP/IPV recipients compared with 6.6-11.1% of DTaP/IPV recipients; the corresponding proportions for redness >50mms was 7.0% for TdaP/IPV and 13.3-17.7% for DTaP/IPV recipients. Among the latter, the addition of Hib did not affect the frequency or size of local reactions. Pain at the injection site and systemic symptoms did not differ between the four vaccine groups. A history of atopy was not associated with development of local swelling or redness. A total of 13 children (1.3%) experienced an ESL, three after TdaP/IPV. ESLs resolved without systemic upset within a few days and were usually painless; medical advice was only sought for two children. Parents should be informed about the possible occurrence of an ESL with the pre-school aP-containing booster vaccine but can be reassured that it is a benign and transient condition.

Purpose This longitudinal investigation examined potential risk factors for intimate partner violence (IPV) among women during pregnancy and 6 weeks postpartum. Methods A sample of 180 pregnant women was collected in order to investigate 1) whether associations between partner alcohol misuse, partner jealousy, partner suspicion of infidelity, and stress were associated with IPV victimization, 2) the indirect effects of alcohol misuse on these relationships, and 3) factors related to changes in IPV victimization over time. Results At baseline, partner alcohol misuse was associated with each type of IPV victimization and the combination of partner alcohol misuse, partner jealousy, and partner suspicion of infidelity was most strongly associated with severe physical victimization. Partner alcohol misuse mediated the relationship between partner jealousy and psychological and severe physical victimization. At follow-up, partner jealousy and stress were related to women’s psychological victimization and partner alcohol misuse was related to women’s severe physical victimization. Conclusions Findings suggest that partner alcohol misuse is a risk factor for women’s IPV victimization during pregnancy and jealousy and stress may increase risk for some types of IPV. Findings also suggest that intervention should target parents early in pregnancy in order to reduce the risk for future IPV. PMID:23053216

Intimate partner violence (IPV) has only attracted limited attention in Korea despite numerous studies in Western countries that indicate IPV is associated with depressive symptoms. This study examined the association of IPV with depressive symptoms and suicidal ideation as moderated by the perceived gender roles of married women in South Korea. We analyzed a data set of 4659 married females from the 8th wave of the Korea Welfare Panel Study. Participants were categorized into three groups of non-IPV, non-physical IPV, and physical IPV. The presence of depressive symptoms and suicidal ideation was then used to predict mental health outcomes. Logistic regression helped to investigate the association of IPV and mental health. Furthermore, an interactive regression of IPV and perceived gender roles was also done. Each type of IPV (non-physical and physical) was significantly associated with depressive symptoms (Odds ratios [ORs]: 1.65 and 4.34; 95% confidence interval [CIs]: 1.28-2.13 and 2.71-7.28, respectively) and suicidal ideation (ORs: 1.40 and 3.84; 95% CIs: 1.06-1.85 and 2.32-6.36, respectively) after adjusting for covariates. In addition, women who experienced IPV and reported having traditional gender roles were also more likely to report depressive symptoms (OR: 4.59; 95% CI: 2.90-7.28) and suicidal ideation (OR: 7.28; 95% CI: 3.56-14.87). Research findings indicate an increasingly marked pattern of work-family conflict in regard to the relationship between traditional gender roles and the effect of IPV on the mental health of women. Policy efforts are needed to reduce IPV as a mental health risk factor and address paternalistic traditions deeply rooted in Korean society that place women in an inferior family status.

Intimate partner violence (IPV) is a major problem that could affect reproductive decision making. The aim of this study is to examine the association between IPV and contraceptive use and assess whether the association varies by receipt of prenatal birth control counseling and race/ethnicity. This study analyzed the 2004-2008 national Pregnancy Risk Assessment Monitoring System (PRAMS) that included 193,310 women with live births in the United States. IPV was determined by questions that asked about physical abuse by a current or former partner in the 12 months before or during pregnancy. The outcome was postpartum contraceptive use (yes vs. no). Multiple logistic regression analyses were conducted to assess the influence of experiencing IPV at different periods (preconception IPV, prenatal IPV, both preconception and prenatal IPV, preconception and/or prenatal IPV). Data were stratified to assess differential effects by race/ethnicity and receipt of birth control counseling. Approximately 6.2% of women reported IPV, and 15.5% reported no postpartum contraceptive use. Regardless of the timing of abuse, IPV-exposed women were significantly less likely to report contraceptive use after delivery. This was particularly true for Hispanic women who reported no prenatal birth control counseling and women of all other racial/ethnic groups who received prenatal birth control counseling. IPV victimization adversely affects the use of contraceptive methods following delivery in women with live births. Birth control counseling by health providers may mitigate these effects; however, the quality of counseling needs further investigation. Better integration of violence prevention services and family planning programs is greatly needed. Consistent with national recommendations by the U.S. Preventive Service Task Force, clinicians and public health workers are strongly encouraged to screen for IPV. Health providers should educate women on effective contraceptive options and discuss long-acting reversible contraceptives that are not partner dependent within the context of abusive relationships.

2002-01-01
The NASA Glenn Research Center successfully demonstrated a transmission-control-protocol/ Internet-protocol- (TCP/IP) based approach to the command and control of onorbit assets over a secure network. This is a significant accomplishment because future NASA missions will benefit by using Internet-standards-based protocols. Benefits of this Internet-based space command and control system architecture include reduced mission costs and increased mission efficiency. The demonstration proved that this communications architecture is viable for future NASA missions. This demonstration was a significant feat involving multiple NASA organizations and industry. Phillip Paulsen, from Glenn's Project Development and Integration Office, served as the overall project lead, and David Foltz, from Glenn's Satellite Networks and Architectures Branch, provided the hybrid networking support for the required Internet connections. The goal was to build a network that would emulate a connection between a space experiment on the International Space Station and a researcher accessing the experiment from anywhere on the Internet, as shown. The experiment was interfaced to a wireless 802.11 network inside the demonstration area. The wireless link provided connectivity to the Tracking and Data Relay Satellite System (TDRSS) Internet Link Terminal (TILT) satellite uplink terminal located 300 ft away in a parking lot on top of a panel van. TILT provided a crucial link in this demonstration. Leslie Ambrose, NASA Goddard Space Flight Center, provided the TILT/TDRSS support. The TILT unit transmitted the signal to TDRS 6 and was received at the White Sands Second TDRSS Ground Station. This station provided the gateway to the Internet. Coordination also took place at the White Sands station to install a Veridian Firewall and automated security incident measurement (ASIM) system to the Second TDRSS Ground Station Internet gateway. The firewall provides a trusted network for the simulated space experiment. A second Internet connection at the demonstration area was implemented to provide Internet connectivity to a group of workstations to serve as platforms for controlling the simulated space experiment. Installation of this Internet connection was coordinated with an Internet service provider (ISP) and local NASA Johnson Space Center personnel. Not only did this TCP/IP-based architecture prove that a principal investigator on the Internet can securely command and control on-orbit assets, it also demonstrated that valuable virtual testing of planned on-orbit activities can be conducted over the Internet prior to actual deployment in space.

Intimate partner violence (IPV) threatens the safety and health of women worldwide. Safety planning is a widely recommended, evidence-based intervention for women experiencing IPV, yet fewer than 1 in 5 Canadian women access safety planning through domestic violence services. Rural, Indigenous, racialized, and immigrant women, those who prioritize their privacy, and/or women who have partners other than men, face unique safety risks and access barriers. Online IPV interventions tailored to the unique features of women's lives, and to maximize choice and control, have potential to reduce access barriers, and improve fit and inclusiveness, maximizing effectiveness of these interventions for diverse groups. In this double blind randomized controlled trial, 450 Canadian women who have experienced IPV in the previous 6 months will be randomized to either a tailored, interactive online safety and health intervention (iCAN Plan 4 Safety) or general online safety information (usual care). iCAN engages women in activities designed to increase their awareness of safety risks, reflect on their plans for their relationships and priorities, and create a personalize action plan of strategies and resources for addressing their safety and health concerns. Self-reported outcome measures will be collected at baseline and 3, 6, and 12 months post-baseline. Primary outcomes are depressive symptoms (Center for Epidemiological Studies Depression Scale, Revised) and PTSD Symptoms (PTSD Checklist, Civilian Version). Secondary outcomes include helpful safety actions, safety planning self-efficacy, mastery, and decisional conflict. In-depth qualitative interviews with approximately 60 women who have completed the trial and website utilization data will be used to explore women's engagement with the intervention and processes of change. This trial will contribute timely evidence about the effectiveness of online safety and health interventions appropriate for diverse life contexts. If effective, iCAN could be readily adopted by health and social services and/or accessed by women to work through options independently. This study will produce contextualized knowledge about how women engage with the intervention; its strengths and weaknesses; whether specific groups benefit more than others; and the processes explaining any positive outcomes. Such information is critical for effective scale up of any complex intervention. Clinicaltrials.gov ID NCT02258841 (Registered on Oct 2, 2014).

The purpose of the study was to (a) explore the relationship between sexual cultural scripting and traditional masculine norms on changes in intimate partner violence (IPV) perpetration, and (b) examine traditional masculine norms as an effect modifier among young heterosexual men. This study is a secondary data analysis of a prospective cohort study of 119 young heterosexual men who were followed for 6 months. The adjusted logistic regression results revealed that sexual cultural scripting norms were associated with an increased odds of emotional IPV perpetration and traditional masculine norms were associated with an increased odds of physical IPV perpetration in the past 6 months. There were no significant interaction effects between sexual cultural scripting and traditional masculine norms on IPV perpetration. These findings suggest that socially constructed norms and beliefs surrounding masculinity, femininity, and how women and men interact in sexual relationships are important constructs for understanding the etiology of young men's use of violence against a female partner. While primary IPV interventions targeting young men do address masculinity, sexual cultural scripting is an additional concept that should also be addressed. © Society for Community Research and Action 2018.
Advanced Mobility Handover for Mobile IPv6 Based Wireless Networks
Safa Sadiq, Ali; Fisal, Norsheila Binti; Ghafoor, Kayhan Zrar; Lloret, Jaime
2014-01-01
We propose an Advanced Mobility Handover scheme (AMH) in this paper for seamless mobility in MIPv6-based wireless networks. In the proposed scheme, the mobile node utilizes a unique home IPv6 address developed to maintain communication with other corresponding nodes without a care-of-address during the roaming process. The IPv6 address for each MN during the first round of AMH process is uniquely identified by HA using the developed MN-ID field as a global permanent, which is identifying uniquely the IPv6 address of MN. Moreover, a temporary MN-ID is generated by access point each time an MN is associated with a particular AP and temporarily saved in a developed table inside the AP. When employing the AMH scheme, the handover process in the network layer is performed prior to its default time. That is, the mobility handover process in the network layer is tackled by a trigger developed AMH message to the next access point. Thus, a mobile node keeps communicating with the current access point while the network layer handover is executed by the next access point. The mathematical analyses and simulation results show that the proposed scheme performs better as compared with the existing approaches. PMID:25614890

2000-01-01
This paper outlines the main results of a number of ACTS experiments on the efficacy of using standard Internet protocols over long-delay satellite channels. These experiments have been jointly conducted by NASAs Glenn Research Center and Ohio University over the last six years. The focus of our investigations has been the impact of long-delay networks with non-zero bit-error rates on the performance of the suite of Internet protocols. In particular, we have focused on the most widely used transport protocol, the Transmission Control Protocol (TCP), as well as several application layer protocols. This paper presents our main results, as well as references to more verbose discussions of our experiments.

The growth of the Internet has led to significant change and has become an integral part of modern life. It has made life easier and provided innumerous benefits; however, excessive use has brought about the potential for addiction, leading to severe impairments in social, academic, financial, psychological, and work domains. Individuals addicted to the Internet usually have comorbid psychiatric disorders. Panic disorder (PD) and generalized anxiety disorder (GAD) are prevalent mental disorders, involving a great deal of damage in the patient's life. This open trial study describes a treatment protocol among 39 patients with anxiety disorders and Internet addiction (IA) involving pharmacotherapy and modified cognitive behavioral therapy (CBT). Of the 39 patients, 25 were diagnosed with PD and 14 with GAD, in addition to Internet addiction. At screening, patients responded to the MINI 5.0, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Clinical Global Impressions Scale, and the Young Internet Addiction Scale. At that time, IA was observed taking into consideration the IAT scale (cutoff score above 50), while anxiety disorders were diagnosed by a psychiatrist. Patients were forwarded for pharmacotherapy and a modified CBT protocol. Psychotherapy was conducted individually, once a week, over a period of 10 weeks, and results suggest that the treatment was effective for anxiety and Internet addiction. Before treatment, anxiety levels suggested severe anxiety, with an average score of 34.26 (SD 6.13); however, after treatment the mean score was 15.03 (SD 3.88) (P<.001). A significant improvement in mean Internet addiction scores was observed, from 67.67 (SD 7.69) before treatment, showing problematic internet use, to 37.56 (SD 9.32) after treatment (P<.001), indicating medium Internet use. With respect to the relationship between IA and anxiety, the correlation between scores was .724. This study is the first research into IA treatment of a Brazilian population. The improvement was remarkable due to the complete engagement of patients in therapy, which contributed to the success of the treatment from a behavioral perspective, and gave patients the confidence to continue to manage Internet use in their lives.

Mechanisms of Partner Violence Reduction in a Group HIV-Risk Intervention for Hispanic Women.
McCabe, Brian E; Gonzalez-Guarda, Rosa M; Peragallo, Nilda P; Mitrani, Victoria B
2016-08-01
The objective of this study was to test whether partner communication about HIV and/or alcohol intoxication mediated reductions in intimate partner violence (IPV) in SEPA (Salud [health], Educación [education], Promoción [promotion], y [and] Autocuidado [self-care]), a culturally specific, theoretically based group HIV-risk reduction intervention for Hispanic women. SEPA had five sessions covering sexually transmitted infection (STI)/HIV prevention, partner communication, condom negotiation and use, and IPV. SEPA reduced IPV and alcohol intoxication, and improved partner communication compared with controls in a randomized trial with adult U.S. Hispanic women (SEPA, n = 274; delayed intervention control, n = 274) who completed structured interviews at baseline and 3, 6, and 12 months post-baseline. Parallel process latent growth curve models indicated that partner communication about HIV mediated the reduction in male-to-female IPV in SEPA, B = -0.78, SE = 0.14, p< .001, but alcohol intoxication did not, B = -0.15, SE = 0.19, p = .431. Male-to-female IPV mediated the intervention effect on female-to-male IPV, B = -1.21, SE = 0.24, p< .001. Skills building strategies originally designed to enhance women's communication with their partners about sexual risk behaviors also worked to reduce male-to-female IPV, which in turn reduced female-to-male IPV. These strategies could be integrated into other types of health promotion interventions. © The Author(s) 2015.

Objective Evidence has linked economic hardship with increased intimate partner violence (IPV) perpetration among males. However, less is known about how economic debt or gender norms related to men's roles in relationships or the household, which often underlie IPV perpetration, intersect in or may explain these associations. We assessed the intersection of economic debt, attitudes toward gender norms, and IPV perpetration among married men in India. Methods Data were from the evaluation of a family planning intervention among young married couples (n=1,081) in rural Maharashtra, India. Crude and adjusted logistic regression models for dichotomous outcome variables and linear regression models for continuous outcomes were used to examine debt in relation to husbands' attitudes toward gender-based norms (i.e., beliefs supporting IPV and beliefs regarding male dominance in relationships and the household), as well as sexual and physical IPV perpetration. Results Twenty percent of husbands reported debt. In adjusted linear regression models, debt was associated with husbands' attitudes supportive of IPV (b=0.015, p=0.004) and norms supporting male dominance in relationships and the household (b=0.006, p=0.003). In logistic regression models adjusted for relevant demographics, debt was associated with perpetration of physical IPV (adjusted odds ratio [AOR] = 1.4, 95% confidence interval [CI] 1.1, 1.9) and sexual IPV (AOR=1.6, 95% CI 1.1, 2.1) from husbands. These findings related to debt and relation to IPV were slightly attenuated when further adjusted for men's attitudes toward gender norms. Conclusion Findings suggest the need for combined gender equity and economic promotion interventions to address high levels of debt and related IPV reported among married couples in rural India.

LoWMob: Intra-PAN Mobility Support Schemes for 6LoWPAN

Mobility in 6LoWPAN (IPv6 over Low Power Personal Area Networks) is being utilized in realizing many applications where sensor nodes, while moving, sense and transmit the gathered data to a monitoring server. By employing IEEE802.15.4 as a baseline for the link layer technology, 6LoWPAN implies low data rate and low power consumption with periodic sleep and wakeups for sensor nodes, without requiring them to incorporate complex hardware. Also enabling sensor nodes with IPv6 ensures that the sensor data can be accessed anytime and anywhere from the world. Several existing mobility-related schemes like HMIPv6, MIPv6, HAWAII, and Cellular IP require active participation of mobile nodes in the mobility signaling, thus leading to the mobility-related changes in the protocol stack of mobile nodes. In this paper, we present LoWMob, which is a network-based mobility scheme for mobile 6LoWPAN nodes in which the mobility of 6LoWPAN nodes is handled at the network-side. LoWMob ensures multi-hop communication between gateways and mobile nodes with the help of the static nodes within a 6LoWPAN. In order to reduce the signaling overhead of static nodes for supporting mobile nodes, LoWMob proposes a mobility support packet format at the adaptation layer of 6LoWPAN. Also we present a distributed version of LoWMob, named as DLoWMob (or Distributed LoWMob), which employs Mobility Support Points (MSPs) to distribute the traffic concentration at the gateways and to optimize the multi-hop routing path between source and destination nodes in a 6LoWPAN. Moreover, we have also discussed the security considerations for our proposed mobility schemes. The performance of our proposed schemes is evaluated in terms of mobility signaling costs, end-to-end delay, and packet success ratio. PMID:22346730

Disrupting women's employment is a strategy that abusive partners could use to prevent women from maintaining economic independence and stability. Yet, few studies have investigated disruptions in employment among victims of intimate partner violence (IPV) in low-income and middle-income countries. Moreover, even fewer have sought to identify which female victims of IPV are most vulnerable to such disruptions. Using baseline data from 947 women in Mexico City enrolled in a randomised controlled trial, multilevel latent class analysis (LCA) was used to classify women based on their reported IPV experiences. Furthermore, multilevel logistic regression analyses were performed on a subsample of women reporting current work (n=572) to investigate associations between LCA membership and IPV-related employment disruptions. Overall, 40.6% of women who were working at the time of the survey reported some form of work-related disruption due to IPV. LCA identified four distinct classes of IPV experiences: Low Physical and Sexual Violence (39.1%); High Sexual and Low Physical Violence class (9.6%); High Physical and Low Sexual Violence and Injuries (36.5%); High Physical and Sexual Violence and Injuries (14.8%). Compared with women in the Low Physical and Sexual Violence class, women in the High Physical and Sexual Violence and Injuries class and women in the High Physical and Low Sexual Violence and Injuries class were at greater risk of work disruption (adjusted relative risk (ARR) 2.44, 95% CI 1.80 to 3.29; ARR 2.05, 95% CI 1.56 to 2.70, respectively). No other statistically significant associations emerged. IPV, and specific patterns of IPV experiences, must be considered both in work settings and, more broadly, by economic development programmes.

We address questions about (1) how college women with a disability experience sexual violence (SV) and intimate partner violence (IPV) across partners, including disability-specific abuse and (2) how SV/IPV impacts psychological, behavioral, physical, and academic life domains. Twenty-seven female college students (mean age, 21.2; 66.6% white; 66.6% heterosexual) were randomly sampled from university registrar records. To be eligible for the study, students had to have at least one experience of SV/IPV since age 18 and a disability (88.8% reported one or more mental health conditions; 11.1% reported other conditions, such as attention deficit and hyperactivity disorder; with the majority of women indicating their disability preceded SV/IPV victimization). Using the Centers for Disease Control and Prevention's definitions of SV/IPV as guides, clinically trained master's level interviewers conducted semistructured interviews to ascertain SV/IPV patterns across students' three most recent relationships and related life impacts. SV/IPV was pervasive in college women with a disability, within hookup settings and/or recurring SV/IPV with a long-term partner. For some women, SV spanned multiple abusive partners. For women in relationships marked by chronic abuse, in addition to SV, the relationship dynamic included disability-specific abuse, social isolation, threats/intimidation, and technology-related abuse. For women experiencing SV events within hookup settings, alcohol was a common facilitator, with some abusers using a disability to manipulate a sexual connection. All but one participant reported exacerbated adverse mental health consequences (e.g., depression, anxiety, post-traumatic stress disorder, suicidal ideation/attempts, stress) after victimization. These adverse mental health consequences coincided with adverse behavioral (e.g., becoming less social, avoiding usual study lounge areas on campus), physical (e.g., problems sleeping, bruising, pregnancy concerns, and sexually transmitted disease), and academic outcomes (e.g., skipping and/or dropping class, grades suffering). Our results underscore the need for continued investment in campus programs that improve response to SV/IPV, including prevention programs and support services tailored to the specific needs and vulnerabilities of women with underlying mental health conditions.

Alcohol misuse is associated with increased human immunodeficiency virus sexual risk behaviors by women. Drug use, intimate partner violence (IPV), and depressive symptoms frequently co-occur, are well-recognized alcohol misuse comorbidities, and may interact to increase risk behaviors. Using a syndemic framework we examined associations between drug use, IPV, and depressive symptoms and sexual risk behaviors by 400 women with alcohol misuse attending an urban sexually transmitted infections clinic. Participants completed computer-assisted interviews querying drug use, IPV, and depressive symptoms and sexual risk behavior outcomes-unprotected sex under the influence of alcohol, sex for drugs/money, and number of lifetime sexual partners. We used multivariable analysis to estimate prevalence ratios (PR) for independent and joint associations between drug use, IPV, and depressive symptoms and our outcomes. To investigate synergy between risk factors we calculated the relative excess prevalence owing to interaction for all variable combinations. In multivariable analysis, drug use, IPV, and depressive symptoms alone and in combination were associated with higher prevalence/count of risk behaviors compared with women with alcohol misuse alone. The greatest prevalence/count occurred when all three were present (unprotected sex under the influence of alcohol [PR, 2.6; 95% confidence interval, 1.3-4.9]), sex for money or drugs [PR, 2.6; 95% confidence interval, 1.7-4.2], and number of lifetime partners [PR, 3.2; 95% confidence interval, 1.9-5.2]). Drug use, IPV, and depressive symptoms did not interact synergistically to increase sexual risk behavior prevalence. A higher prevalence of sexual risk behaviors by women with alcohol misuse combined with drug use, IPV, and depressive symptoms supports the need for alcohol interventions addressing these additional comorbidities.

Posttraumatic stress disorder resulting from intimate partner violence (IPV-related PTSD), drug problems, and alcohol problems were tested as correlates of women’s sexual risk behavior. Participants were 136 low-income women experiencing physical violence by a male partner during the past 6 months. Sexual risk behavior was assessed by whether women had unprotected sex with a risky primary partner (i.e., HIV-positive, injection drug user, and/or nonmonogamous), unprotected sex with a risky nonprimary partner (i.e. HIV-positive or unknown status), or traded sex during the past 6 months. Nearly one in five women engaged in these recent sexual risk behaviors. Simultaneous logistic regression results revealed IPV-related PTSD, but not drug or alcohol problems, was significantly associated with sexual risk behavior while controlling for childhood abuse and demographic covariates. Women with IPV-related PTSD had four times greater odds of recent sexual risk behavior compared to women without IPV-related PTSD. Implications for HIV prevention interventions are discussed.

As multiple vaccines are administered concomitantly during routine pediatric immunizations, it is important to ascertain the potential interference of any new vaccine on the immune response to the concomitantly administered vaccines. Immune responses to meningococcal serogroup C-tetanus toxoid conjugate vaccine (MnCC-TT) and the diphtheria and tetanus antigens in routine pediatric vaccines (diphtheria, tetanus, acellular pertussis-hepatitis B virus-inactivated poliovirus/Haemophilus influenza type b [DTaP-HBV-IPV/Hib] and DTaP-IPV+Hib) when given concomitantly with the 13-valent pneumococcal conjugate vaccine (PCV13) were compared with responses when given with PCV7. In addition, the immunogenicity and safety of PCV13 were assessed. Healthy infants were randomized to receive PCV13 or PCV7 (ages 2, 4, 6 and 15 months), concomitant with MnCC-TT (2, 4 and 15 months), DTaP-HBV-IPV/Hib (2, 4 and 6 months), and DTaP-IPV+Hib (15 months). Immune responses to MnCC-TT and to the diphtheria and tetanus antigens administered with PCV13 were noninferior to the responses observed when the vaccines were administered with PCV7; ≥96.6 (postinfant) and ≥99.4% (posttoddler) subjects achieved prespecified immune response levels to each antigen in each group. After the infant series, ≥93.0% of subjects receiving PCV13 achieved pneumococcal anticapsular immunoglobulin G concentrations ≥0.35 µg/mL for all serotypes except serotype 3 (86.2%), increasing to 98.1-100% for most serotypes (serotype 3: 93.6%) after the toddler dose. Local and systemic reactions were similar between groups. Immune responses to MnCC-TT, and other childhood vaccines (DTaP-HBV-IPV/Hib, DTaP-IPV+Hib) were noninferior when concomitantly administered with PCV13 compared with PCV7. PCV13 does not interfere with MnCC-TT. PCV13 is highly immunogenic with a favorable safety profile.

The NASA Glenn Research Center recently demonstrated the ability to securely command and control space-based assets by using the Internet and standard Internet Protocols (IP). This is a significant accomplishment because future NASA missions will benefit by using Internet standards-based protocols. The benefits include reduced mission costs and increased mission efficiency. The Internet-Based Space Command and Control System Architecture demonstrated at the NASA Inspection 2000 event proved that this communications architecture is viable for future NASA missions.

This randomized trial enrolled 442 infants in the Republic of Korea to assess the immunogenicity and safety of a combined diphtheria, tetanus, acellular pertussis, and inactivated poliovirus vaccine (DTaP-IPV; Tetraxim™) for primary vaccination at 2, 4 and 6 months of age compared with DTaP and IPV vaccines given separately. Immunogenicity was high in both groups; seroprotection and seroconversion rates of the combined vaccine (Group A) were non-inferior to the control vaccines (Group B). All subjects were seroprotected against poliovirus types 1, 2 and 3 (≥ 81/dil) and anti-diphtheria (≥ 0.01 IU/mL); 99.0% were seroprotected against tetanus (≥ 0.1 IU/mL). At least 93.6% had anti-diphtheria antibody titers ≥ 0.1 IU/mL. Anti-pertussis toxoid (PT) and anti-filamentous haemagglutinin (FHA) seroconversion (≥ 4-fold increase in antibody titer) rates were 96.6% and 94.4% for Group A, 92.2% and 78.4% for Group B. Most solicited reactions occurred within 4 days of vaccination, resolved within 3 days and were mild. Severe solicited reactions occurred after ≤ 0.5% of doses in Group A and ≤ 0.9% in Group B. No withdrawals occurred because of adverse events. The DTaP-IPV combined vaccine given at 2, 4, and 6 months of age was well tolerated; immunogenicity was similar to the control vaccines.

Following the declaration of eradication of wild poliovirus (WPV) type 2 in September 2015, trivalent oral poliovirus vaccine (tOPV) was withdrawn globally to reduce the risk for type 2 vaccine-derived poliovirus (VDPV2) transmission; all countries implemented a synchronized switch to bivalent OPV (type 1 and 3) in April 2016 (1,2). Any isolation of VDPV2 after the switch is to be treated as a potential public health emergency and might indicate the need for supplementary immunization activities (3,4). On August 9, 2016, VDPV2 was isolated from a sewage sample taken from an environmental surveillance site in Hyderabad, Sindh province, Pakistan. Possible vaccination activities in response to VDPV2 isolation include the use of injectable inactivated polio vaccine (IPV), which poses no risk for vaccine-derived poliovirus transmission. Fractional-dose, intradermal IPV (fIPV), one fifth of the standard intramuscular dose, has been developed to more efficiently manage limited IPV supplies. fIPV has been shown in some studies to be noninferior to full-dose IPV (5,6) and was used successfully in response to a similar detection of a single VDPV2 isolate from sewage in India (7). Injectable fIPV was used for response activities in Hyderabad and three neighboring districts. This report describes the findings of an assessment of preparatory activities and subsequent implementation of the fIPV campaign. Despite achieving high coverage (>80%), several operational challenges were noted. The lessons learned from this campaign could help to guide the planning and implementation of future fIPV vaccination activities.

Intimate partner violence (IPV) is a significant and largely hidden public health problem for all women and, during pregnancy, can have significant effects on the health of both mother and the unborn baby. Previous Namibian studies suggest rates of IPV as high as 36%, although few studies have been conducted in primary care. To determine the prevalence of IPV amongst women attending antenatal care. Outapi primary care clinic, Namibia. A descriptive survey administering a validated questionnaire to 386 consecutive participants. The mean age of the participants was 27.5 years (standard deviation = 6.8), 335 (86.8%) were unmarried, 215 (55.7%) had only primary school education and 237 (61.4%) were in their third trimester. Overall, 51 participants (13.2%) had HIV and 44 (11.4%) had teenage pregnancies. The reported lifetime prevalence of IPV was 39 (10.1%), the 12-month prevalence was 35 (9.1%) and the prevalence during pregnancy was 31 (8.0%). Emotional abuse was the commonest type of abuse in 27 (7.0%). The commonest specific abusive behaviour was refusing to provide money to run the house or look after the children whilst the partner spent money on his priorities (4.9%). Increased maternal age was associated with an increase in the occurrence of IPV. The reported lifetime prevalence of IPV was 10.1%, with emotional abuse being the commonest type of abuse. Increased age was associated with an increase in reported IPV. IPV is significant enough to warrant that healthcare providers develop guidelines to assist women affected by IPV in Namibia.

Veterans are at heightened risk for perpetrating intimate partner violence (IPV), yet there is limited evidence to inform practice and policy for the detection of IPV perpetration. The present study evaluated the accuracy and acceptability of a potential IPV perpetration screening tool for use with women veterans. A national sample of women veterans completed a 2016 web-based survey that included a modified 5-item Extended-Hurt/Insult/Threaten/Scream (Modified E-HITS) and the Revised Conflict Tactics Scales (CTS-2). Items also assessed women's perceptions of the acceptability and appropriateness of the modified E-HITS questions for use in healthcare settings. Accuracy statistics, including sensitivity and specificity, were calculated using the CTS-2 as the reference standard. Primary measures included the Modified E-HITS (index test), CTS-2 (reference standard), and items assessing acceptability. This study included 187 women, of whom 31 women veterans (16.6%) reported past-6-month IPV perpetration on the CTS-2. The Modified E-HITS demonstrated good overall accuracy (area under the curve, 0.86; 95% confidence interval, 0.78-0.94). In addition, the majority of women perceived the questions to be acceptable and appropriate. Findings demonstrate that the Modified E-HITS is promising as a low-burden tool for detecting of IPV perpetration among women veterans. This tool may help the Veterans Health Administration and other health care providers detect IPV perpetration and offer appropriate referrals for comprehensive assessment and services.

Intimate partner violence (IPV) is a global public health problem that affects women's physical, mental, sexual and reproductive health. Very little data on IPV experience and FP use is available in resource-poor settings, such as in West Africa. The aim of this study was to describe the prevalence, patterns and correlates of IPV among clients of an adult Family Planning clinic in Conakry, Guinea. The study data was collected for four months (March to June 2014) from women's family planning charts and from an IPV screening form at the Adult Family Planning and Reproductive Health Clinic of "Association Guinéenne pour le Bien-Etre Familial", a non-profit organization in Conakry, Guinea. 232 women out of 245 women who attended the clinic for services during the study period were screened for IPV and were included in this study. Of the 232 women screened, 213 (92%) experienced IPV in one form or another at some point in their lifetime. 169 women reported psychological violence (79.3%), 145 reported sexual violence (68.1%) and 103 reported physical violence (48.4%). Nearly a quarter of women reported joint occurrence of the three forms of violence(24%).Half of the IPV positive women were current users of family planning (51.2%) and of these, 77.9% preferred injectable contraceptives. The odds of experiencing IPV was higher in women with secondary or vocational level of education than those with higher level of education (AOR: 8.4; 95% CI 1.2-58.5). Women residing in other communes of Conakry (AOR: 5.6; 95% CI 1.4-22.9) and those preferring injectable FP methods (AOR: 4.5; 95% CI 1.2-16.8) were more likely to experience lifetime IPV. IPV is prevalent among family planning clients in Conakry, Guinea where nine out of ten women screened in the AGBEF adult clinic reported having experienced one or another type of IPV. A holistic approach that includes promotion of women's rights and gender equality, existence of laws and policies is needed to prevent and respond to IPV, effective implementation of policies and laws, and access to quality IPV services in Guinea and countries with higher rates of IPV.

ABSTRACT Objective Prevalence of intimate partner violence (IPV) during pregnancy is estimated to be 4%–8%. Women with mental health difficulties are at increased risk for IPV during the perinatal period. Prevalence of IPV is high among women with eating disorders (ED); however, prevalence of IPV during the perinatal period among women with ED is unknown. Method We studied women from a population‐based cohort, the Avon Longitudinal Study of Parents and Children. Prevalence and odds of physical and emotional IPV during and after the perinatal period was investigated among women with lifetime ED, with (n = 174) or without pregnancy shape and weight concern and/or purging behaviors (n = 189), and women with no ED (n = 8723). Results Women with lifetime ED showed higher prevalence of IPV during and after the perinatal period (physical = 9.6%–14.3% and emotional = 24.1%–28.1%). Lifetime ED was associated with higher odds of physical IPV during the perinatal period (odds ratio: 2.34, 95% confidence interval: 1.11–4.93, p = .03). Lifetime ED with and without pregnancy shape and weight concerns and/or purging was associated with higher odds of IPV after the perinatal period, and higher odds of reporting emotional IPV at all time points. Associations were moderated by partner's response to pregnancy and maternal experience of childhood sexual abuse. Discussion Mothers with ED and their children may be vulnerable to negative effects due to maternal ED and IPV combined, both of which have been associated with severe and long‐lasting harmful consequences. Partner's response to pregnancy and maternal experience of childhood sexual abuse might contribute to the association between ED and IPV perinatally. © 2015 The Authors.

The article estimates the prevalence and sociodemographic correlates of intimate partner violence (IPV) by type and severity in population-based samples from three countries of the former Soviet Union (fSU). The article utilized nationally representative data from the Demographic and Health Surveys (DHS) conducted in Azerbaijan (2006), Moldova (2005), and Ukraine (2007). Respondents were selected using stratified multistage cluster sampling. The sample included ever-married (or cohabitating) females of reproductive age (15-49 years old); weighted sample n = 3,847 in Azerbaijan, n = 4,321 in Moldova, and n = 2,355 in Ukraine. The analysis used multinomial survey logistic regression adjusting for the sampling design and sampling weights. Ten percent of ever-partnered women in Azerbaijan and Ukraine and 20% in Moldova ever experienced physical IPV (without sexual) from their most recent husband or cohabitating partner; 3% of women in Azerbaijan and Ukraine and 5% in Moldova experienced sexual IPV (with or without physical), and 2% of women in Azerbaijan, 3% in Ukraine, and 6% in Moldova experienced violence resulting in severe physical injuries from their most recent partner. In all three countries physical, sexual, and injurious IPV was higher among formerly married women. Compared to women with above secondary education, women with secondary education or below demonstrated higher risk for physical IPV (in Moldova and Ukraine), sexual IPV in Moldova, and injurious IPV in all three countries. Poor socioeconomic status-as indicated by low household wealth status in Azerbaijan and partner's unemployment in Moldova and Ukraine-was significantly associated with higher risk for physical and injurious IPV. In Moldova and Ukraine partners' low level of education was associated with higher risk for sexual IPV. The article demonstrates that experiences and factors associated with IPV are diverse and context specific. The findings may be helpful in targeting interventions to sociodemographic groups disproportionately affected by IPV in these three transitional countries.

This greenbook captures some of the current, planned and possible future uses of the Internet Protocol (IP) as part of Space Operations. It attempts to describe how the Internet Protocol is used in specific scenarios. Of primary focus is low-earth-orbit space operations, which is referred to here as the design reference mission (DRM). This is because most of the program experience drawn upon derives from this type of mission. Application profiles are provided. This includes parameter settings programs have proposed for sending IP datagrams over CCSDS links, the minimal subsets and features of the IP protocol suite and applications expected for interoperability between projects, and the configuration, operations and maintenance of these IP functions. Of special interest is capturing the lessons learned from the Constellation Program in this area, since that program included a fairly ambitious use of the Internet Protocol.
Enhanced Predictive Handover for Fast Proxy Mobile IPv6
NASA Astrophysics Data System (ADS)
Jeon, Seil; Kang, Namhi; Kim, Younghan
Proxy Mobile IPv6 (PMIPv6) has been proposed in order to overcome the limitations of host-based mobility management in IPv6 networks. However, packet losses during doing handover are still a problem. To solve this issue, several schemes have been developed, and can be classified into two approaches: predictive and reactive handover. Both approaches commonly use bi-directional tunnel between mobile access gateways (MAGs). In predictive schemes especially, mobility support for a mobile node (MN) is triggered by simplified link signal strength. Thereafter, the MN sends handover notification to its serving MAG, and is then able to initiate packet forwarding. Therefore, if the MN moves toward an unexpected MAG that does not have any pre-established tunnel with the serving MAG, it may lead to packet losses. In this paper, we define this problem as Early Packet Forwarding (EPF). As a solution, we propose an enhanced PMIPv6 scheme using two-phase tunnel control based on the IEEE 802.21 Media Independent Handover (MIH).

Intimate partner violence (IPV) has been increasingly recognised as a major public health and human rights problem that cuts across all populations, irrespective of social, economic, religious or cultural groups. The objectives of this study were to determine the prevalence, pattern and correlates of IPV among women attending the General Out Patient Clinic of Aminu Kano Teaching Hospital, Kano, Nigeria. It was also designed to determine the pattern of health complications associated with IPV as well as the perception of women on intimate partner violence. This was a cross-sectional, hospital-based study. Three hundred and ninety-three women aged 15-49 years who were in or had ever been in an intimate relationship were recruited. An interviewer-administered questionnaire was used to collect data about their socio-demographic characteristics while information on IPV was obtained using the Composite Abuse Scale. The data were analysed using the Statistical Package for Social Science (SPSS) version 16.0. The prevalence of IPV within the previous year was 42.0%. Of all the 393 participants recruited in the study, 46.6% had experienced emotional/psychological violence, harassment/controlling behaviour was present in 43.3%, physical violence was reported in 29.0%, sexual violence was present in 21.9% and 37.9% of the participants had experienced severe combined abuse. Being married (χ2 = 24.726, p = 0.000) and pregnancy reduced the risk of IPV (χ2= 6.690, p = 0.030), while polygamous family setting (χ2 = 9.734, p = 0.008) and an extended family type (χ2 = 9.593, p = 0.023) were associated with an increased risk of IPV. Alcohol consumption by the partner (p = 0.000, OR 2.335, CI 1.151-3.230) was found to be a positive correlate as well as a complication of IPV. Other patterns of health complications that were significantly associated with IPV were depression (p = 0.000, OR 3.517, CI 4.061-22.306), miscarriage (p = 0.004, OR 2.080, CI 1.591-2.269) and the presence of physical injuries in the participants (p = 0.024, OR 2.405, CI 2.345-4.234). One hundred and fifty-nine (40.5%) of the participants agreed that a husband is justified for beating or hitting his wife and neglecting the child was the reason given by most of the participants (26.7%) to justify IPV. The high prevalence of IPV among women of reproductive age in this study shows that it is an important problem that women would rather not talk about or have accepted as a norm. It is associated with poor physical and mental health of women who are victims. It is therefore recommended that physicians routinely screen for IPV especially in patients with depressive symptoms, miscarriage and physical injuries. Screening will be a safe and cost-effective means for identifying women experiencing IPV, leading to appropriate interventions that will decrease further exposure to IPV and its adverse health consequences.

The objectives were to estimate the prevalence of physical and sexual intimate partner violence (IPV) among a regional sample of the general obstetric population as the lifetime prevalence, as the 1-year period prevalence before pregnancy, and as the prevalence during the index pregnancy; to assess the rates of disclosure and help-seeking behaviour with IPV; and to determine the acceptability of screening for IPV. A multi-centred survey surveillance study was carried out among pregnant women attending five large hospitals in the province of East Flanders, Belgium as a regional probability sample of the general obstetric population. Data were collected through an anonymous, written questionnaire that included the Abuse Assessment Screen and additional questions on the circumstances of the most recent episode of physical or sexual violence, on disclosure and help-seeking behaviour, on reporting assault to the police, and on the acceptability of routine screening for IPV. The sampling frame consisted of 1362 women who received the questionnaire at the antenatal service during a 2-month study period, of which 537 (mean age 29.4 years, S.D. 4.09) returned the envelope (response rate 39.4%). The lifetime prevalence of IPV was estimated to be 10.1% (95% CI 7.7-13.0%) and the period prevalence of IPV during pregnancy and/or in the year preceding pregnancy 3.4% (95% CI 2.1-5.4%). There was a significant difference in the reported lifetime prevalence of IPV between women attending with a partner and those who came to the prenatal visit unattended by their partner in particular (6.8% versus 13.9%, p=0.010). Overall, only 19.2% (23 out of 120) and as few as 6.6% (4 out of 61) of the victims of physical and sexual abuse respectively sought medical care by consulting a general practitioner, gynaecologist, or an emergency department. Routine screening for IPV by a general practitioner or gynaecologist was found to be largely acceptable. In our highly medicalised society, women experiencing partner violence rarely disclose abuse to the widely available health care services, unless they are directly asked about it, which appears an acceptable practice. Hence, there is a definite need to improve women's awareness regarding abuse and their help-seeking behaviour at a public health level.

Background Intimate partner violence (IPV), defined as actual or threatened physical, sexual, psychological, and emotional abuse by current or former partners is a global public health concern. The prevalence and determinants of intimate partner violence (IPV) against pregnant women has not been described in Rwanda. A study was conducted to identify variables associated with IPV among Rwandan pregnant women. Methods A convenient sample of 600 pregnant women attending antenatal clinics were administered a questionnaire which included items on demographics, HIV status, IPV, and alcohol use by the male partner. Mean age and proportions of IPV in different groups were assessed. Odds of IPV were estimated using logistic regression analysis. Results Of the 600 respondents, 35.1% reported IPV in the last 12 months. HIV+ pregnant women had higher rates of all forms of IVP violence than HIV- pregnant women: pulling hair (44.3% vs. 20.3%), slapping (32.0% vs. 15.3%), kicking with fists (36.3% vs. 19.7%), throwing to the ground and kicking with feet (23.3% vs. 12.7%), and burning with hot liquid (4.1% vs. 3.5%). HIV positive participants were more than twice likely to report physical IPV than those who were HIV negative (OR = 2.38; 95% CI [1.59, 3.57]). Other factors positively associated with physical IPV included sexual abuse before the age of 14 years (OR = 2.69; 95% CI [1.69, 4.29]), having an alcohol drinking male partner (OR = 4.10; 95% CI [2.48, 6.77] for occasional drinkers and OR = 3.37; 95% CI [2.05, 5.54] for heavy drinkers), and having a male partner with other sexual partners (OR = 1.53; 95% CI [1.15, 2.20]. Education was negatively associated with lifetime IPV. Conclusion We have reported on prevalence of IPV violence among pregnant women attending antenatal care in Rwanda, Central Africa. We advocate that screening for IPV be an integral part of HIV and AIDS care, as well as routine antenatal care. Services for battered women should also be made available. PMID:18847476

Background Intimate partner violence (IPV) and termination of pregnancy (TOP) are global health concerns, but their interaction is undetermined. The aim of this study was to determine whether there is an association between IPV and TOP. Methods and Findings A systematic review based on a search of Medline, Embase, PsycINFO, and Ovid Maternity and Infant Care from each database's inception to 21 September 2013 for peer-reviewed articles of any design and language found 74 studies regarding women who had undergone TOP and had experienced at least one domain (physical, sexual, or emotional) of IPV. Prevalence of IPV and association between IPV and TOP were meta-analysed. Sample sizes ranged from eight to 33,385 participants. Worldwide, rates of IPV in the preceding year in women undergoing TOP ranged from 2.5% to 30%. Lifetime prevalence by meta-analysis was shown to be 24.9% (95% CI 19.9% to 30.6%); heterogeneity was high (I 2>90%), and variation was not explained by study design, quality, or size, or country gross national income per capita. IPV, including history of rape, sexual assault, contraceptive sabotage, and coerced decision-making, was associated with TOP, and with repeat TOPs. By meta-analysis, partner not knowing about the TOP was shown to be significantly associated with IPV (pooled odds ratio 2.97, 95% CI 2.39 to 3.69). Women in violent relationships were more likely to have concealed the TOP from their partner than those who were not. Demographic factors including age, ethnicity, education, marital status, income, employment, and drug and alcohol use showed no strong or consistent mediating effect. Few long-term outcomes were studied. Women welcomed the opportunity to disclose IPV and be offered help. Limitations include study heterogeneity, potential underreporting of both IPV and TOP in primary data sources, and inherent difficulties in validation. Conclusions IPV is associated with TOP. Novel public health approaches are required to prevent IPV. TOP services provide an opportune health-based setting to design and test interventions.

Our purpose was to estimate the national prevalence of intimate partner violence (IPV) among delivery-related discharges and to investigate its association with adverse feto-maternal birth outcomes and delivery-related cost. A retrospective cross-sectional analysis of delivery-related hospital discharges from 2002 to 2009 was conducted using the Nationwide Inpatient Sample (NIS). We used ICD-9-CM codes to identify IPV, covariates, and outcomes. Multivariable logistic regression modeling was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) for the associations between IPV and each outcome. Joinpoint regression was used for trend analysis. During the study period, 3,649 delivery-related discharges were diagnosed with IPV (11.2 per 100,000; 95% CI = [10.0, 12.4]). IPV diagnosis during delivery is associated with stillbirth (AOR = 4.12, 95% CI = [2.75, 6.17]), preterm birth (AOR = 1.97, 95% CI = [1.59, 2.44]), fetal death (AOR = 3.34, 95% CI = [1.99, 5.61]), infant with poor intrauterine growth (AOR = 1.55, 95% CI = [1.01, 2.40]), and increased inpatient hospital care cost (US$5,438.2 vs. US$4,080.1) per each discharge, incurring an additional cost of US$4,955,707 during the study period. IPV occurring during pregnancy has a significant health burden to both the mother and infant. Education about IPV; screening at periodic intervals, including during obstetric visits; and ongoing clinical care could help to reduce or eliminate adverse effects of pregnancy-related IPV. Preventing the lifelong consequences associated with IPV can have a positive effect on the overall health of all women and delivery-related health care cost. © The Author(s) 2014.

Background Intimate partner violence (IPV) against women is a serious public health issue with recognizable direct health consequences. This study assessed the association between IPV and traumatic physical health consequences on women in Nigeria, given that communities exert significant influence on the individuals that are embedded within them, with the nature of influence varying between communities. Methods Cross-sectional nationally-representative data of women aged 15 - 49 years in the 2008 Nigeria Demographic and Health Survey was used in this study. Multilevel logistic regression analysis was used to assess the association between IPV and several forms of physical health consequences. Results Bruises were the most common form of traumatic physical health consequences. In the adjusted models, the likelihood of sustaining bruises (OR = 1.91, 95% CI = 1.05 - 3.46), wounds (OR = 2.54, 95% CI = 1.31 - 4.95), and severe burns (OR = 3.20, 95% CI = 1.63 - 6.28) was significantly higher for women exposed to IPV compared to those not exposed to IPV. However, after adjusting for individual- and community-level factors, women with husbands/partners with controlling behavior, those with primary or no education, and those resident in communities with high tolerance for wife beating had a higher likelihood of experiencing IPV, whilst mean community-level education and women 24 years or younger were at lower likelihood of experiencing IPV. Conclusions Evidence from this study shows that exposure to IPV is associated with increased likelihood of traumatic physical consequences for women in Nigeria. Education and justification of wife beating were significant community-level factors associated with traumatic physical consequences, suggesting the importance of increasing women's levels of education and changing community norms that justify controlling behavior and IPV.

Intimate partner violence (IPV) is a serious public health problem among adolescents. This study investigated the prevalence of and factors associated with Grade 8 girls' experience and boys' perpetration of IPV in South Africa. Participants were interviewed using interviewer-administered questionnaires about IPV, childhood violence, bullying, gender attitudes, alcohol use and risky sexual behaviours. Multiple logistic regression analysis was conducted to assess factors associated with girls' experience and boys' perpetration of IPV. Structural equation modelling (SEM) was conducted to assess the pathways to IPV experience and perpetration. Results show dating relationships are common among girls (52.5%) and boys (70.7%) and high prevalence of sexual or physical IPV experience by girls (30.9%; 95% CI: 28.2-33.7) and perpetration by boys (39.5%; 95% CI: 36.6-42.3). The logistic regression model showed factors associated with girls' experience of IPV include childhood experience of violence, individual gender inequitable attitudes, corporal punishment at home and in school, alcohol use, wider communication with one's partner and being more negative about school. We found three pathways from childhood trauma to IPV experience and perpetration in both models and these are through inequitable gender attitudes and risky sex, bullying and alcohol use. Prevention of IPV in children needs to encompass prevention of exposure to trauma in childhood and addressing gender attitudes and social norms to encourage positive disciplining approaches. : The trial is registered on ClinicalTrials.gov as NCT02349321. © The Author 2015.

To evaluate the immunogenicity and safety of a reduced antigen diphtheria-tetanus-acellular pertussis-inactivated poliovirus (dTap-IPV B ) vaccine (Boostrix-IPV, GSK) as a pre-school booster in 3-4 year old children as compared to dTap-IPV R (Repevax, Sanofi Pasteur), when co-administered with mumps-measles-rubella vaccine (MMRV). This phase III, open label, randomised study was conducted in the UK between April 2011 and April 2012. Children due their pre-school dTap-IPV booster vaccination were randomised 2:1 to receive one of two different dTap-IPV vaccines (dTap-IPV B or dTap-IPV R ) with blood sample for immunogenicity assessment just prior and one month after vaccination. Immune responses to diphtheria, tetanus and polio antigens were compared between the study vaccines (inferential comparison). In the absence of an accepted pertussis correlate of protection, the immunogenicity of dTap-IPV B vaccine against pertussis was compared with historical pertussis efficacy data (inferential comparison). Safety and reactogenicity of both study vaccines were evaluated. 387 children were randomised and 385 vaccinated: 255 in the dTap-IPV B group and 130 in the dTap-IPV R group. Prior to vaccination, ≥76.8% of children had anti-diphtheria and ≥65.5% had anti-tetanus titres above the protection threshold; for pertussis, the pre-vaccination seropositivity rate ranged between 18.1 and 70.6%. Both vaccines were immunogenic with 99.2-100% of children achieving titres above the pre-specified seroprotection/seropositivity thresholds. One serious adverse event not considered as causally related to the study vaccination by the study investigator was reported in the dTap-IPV B group. Non-inferiority of dTap-IPV B to dTap-IPV R was demonstrated. Both vaccines had a clinically acceptable safety and reactogenicity profile when co-administered with MMRV to children 3-4 years old.

Prior research has demonstrated that intimate partner violence (IPV) is associated with employment instability among poor women. The current study assesses the broader relationship between IPV and women's workforce participation in a population-based sample of 6,698 California women. We examined past-year IPV by analyzing specific effects of physical violence, psychological violence, and posttraumatic stress disorder (PTSD) symptoms as predictors of unemployment. Results indicated substantial rates of unemployment among women who reported IPV, with rates of 20% among women who experienced psychological violence, 18% among women who experienced physical violence, and 19% among women with PTSD symptoms. When the relationship was adjusted for demographic characteristics and educational attainment, PTSD (adjusted odds ratio [AOR] = 1.60; 95% confidence interval [CI] = 1.22, 2.09) and psychological violence (AOR = 1.78; 95% CI = 1.36, 2.32), but not physical violence, were associated with unemployment. Implications for supported employment programs and workplace responses to IPV are discussed.

ABSTRACT Multivalent combination vaccines have reduced the number of injections and therefore improved vaccine acceptance, timeliness of administration and global coverage. The hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus/Haemophilus influenzae type b (DTPa-HBV-IPV/Hib; Infanrix hexa™) vaccine, administered according to various schedules, is widely used for the primary vaccination of infants worldwide. In the current publication, we are presenting the immunogenicity and safety of 3 doses of DTPa-HBV-IPV/Hib vaccine when administered to Indian infants. 224 healthy infants (mean age 6.8 weeks) were vaccinated at 6–10–14 weeks (W) of age (n = 112) or 2–4–6 months (M) of age (n = 112). One month after the third vaccine dose, the seroprotection/seropositivity status against diphtheria, pertussis, tetanus, polio, hepatitis B and Hib antigens ranged from 98.6% to 100% in both groups. The vaccine response rate to the pertussis antigens ranged from 97% to 100%. Pain (6–10–14W group: 25.2%; 2–4–6M group: 13.4%) and fever (15.3% and; 15.2%, respectively) were the most frequently reported solicited local and general symptoms. Unsolicited adverse events were reported for 35.7% (6–10–14W group) and 22.3% (2–4–6M group) of subjects. No vaccine related serious adverse events were reported. In conclusion, the hexavalent DTPa-HBV-IPV/Hib vaccine was immunogenic and well tolerated, irrespective of the dosing schedule. PMID:27629913
Latina immigrants, interpersonal violence, and the decision to report to police.
Pitts, Kimberly Mathis
2014-06-01
Interpersonal violence (IPV) occurs across all ethnic and racial groups and affects women of all ages and socioeconomic backgrounds. Battered women of Latin American descent are less likely to seek help from either formal or informal sources and these women are more likely to stay longer in an abusive relationship before seeking help. To contribute to the growing body of literature on IPV, this research will examine particular situational and individual-specific characteristics of IPV incidents experienced by Latina immigrant women living in a metropolitan area in the Southern United States. Based on a sample of 568 immigrant Latina women collected over a 6-year period, this research explains whether particular situational and individual-specific characteristics of IPV incidents affect the decisions of Latina victims to report to the police.

Physical punishment of children is an important public health concern. Yet, few studies have examined how physical punishment is related to other types of child maltreatment and violence across the lifespan. Therefore, the objective of the current study was to examine if harsh physical punishment (i.e., being pushed, grabbed, shoved, hit, and/or slapped without causing marks, bruises, or injury) is associated with an increased likelihood of more severe childhood maltreatment (i.e., physical abuse, emotional abuse, sexual abuse, physical neglect, emotional neglect, and exposure to intimate partner violence (IPV)) in childhood and perpetration or victimization of IPV in adulthood. Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions collected in 2004 to 2005 (n = 34,402, response rate = 86.7%), a representative United States adult sample. Harsh physical punishment was associated with increased odds of childhood maltreatment, including emotional abuse, sexual abuse, physical abuse, physical neglect, emotional neglect, and exposure to IPV after adjusting for sociodemographic factors, family history of dysfunction, and other child maltreatment types (range 1.6 to 26.6). Harsh physical punishment was also related to increased odds of experiencing IPV in adulthood (range 1.4 to 1.7). It is important for parents and professionals working with children to be aware that pushing, grabbing, shoving, hitting, or slapping children may increase the likelihood of emotional abuse, sexual abuse, physical abuse, physical neglect, emotional neglect, and exposure to IPV in childhood and also experiencing IPV victimization and/or perpetration in later adulthood.

Registering study protocols in a trial registry is important for methodologic transparency and reducing selective reporting bias. The objective of this investigation was to determine whether published studies of intimate partner violence (IPV) that had been registered matched the registration record on key study design elements. We systematically searched three trial registries to identify registered IPV studies and the published literature for the associated publication. Two authors independently determined for each study whether key study elements in the registry matched those in the published paper. We included 66 studies published between 2006 and 2017. Nearly half (29/66, 44%) were registered after study completion. Many (26/66, 39%) had discrepancies regarding the primary outcome, and nearly two-thirds (42/66, 64%) had discrepancies in secondary outcomes. Discrepancies in study design were less frequent (13/66, 20%). However, large changes in sample size (26/66, 39%) and discrepancies in funding source (28/66, 42%) were frequently observed. Trial registries are important tools for research transparency and identifying and preventing outcome switching and selective outcome reporting bias. Published IPV studies often differ from their records in trial registries. Researchers should pay close attention to the accuracy of trial registry records.

Studies document a significant association between victimization from intimate partner violence (IPV) and sexually transmitted infections (STIs) and HIV among substance using women in Russia and elsewhere, but no study has examined IPV perpetration and STI among Russian men or HIV-infected men in Eastern Europe. This study was designed to assess the association between lifetime history of IPV perpetration and STI (lifetime and current) among substance using HIV-infected men in Russia. Cross-sectional analyses were conducted with baseline data from 415 male participants enrolled in a randomized HIV intervention clinical trial [the HERMITAGE Study]. Participants were HIV-infected men reporting recent heavy alcohol use and unprotected sex in St. Petersburg, Russia. Baseline surveys assessed demographics, IPV perpetration, risk behaviors, and STI history. Current STI was assessed via blood testing for syphilis and urine testing for gonorrhea, Chlamydia and Trichomonas. Multiple logistic regression analyses were used to assess the association between history of IPV with lifetime and current STI. Participants were aged 20-57 years. Almost half of participants (46%) reported a history of IPV perpetration; 81% reported past 30-day binge alcohol use, and 43% reported past 30-day injection drug use. Past and current STI was 41% and 12%, respectively. Men reporting a history of IPV perpetration had significantly higher odds of reporting ever having an STI (AOR=1.6, 95% CI=1.1, 2.4) but lower odds of testing positive for a current STI (AOR=0.50, 95% CI=0.26, 0.96). These findings demonstrate that a history of male IPV perpetration is common in HIV-infected Russian men and associated with a history of STI. Programmatic work toward IPV prevention is needed in Russia and may be beneficial in mitigating STIs, but more research is needed to understand how and why the association between IPV and STI changes over time in this population.
Economic Coercion and Partner Violence against Wives in Vietnam: A Unified Framework?
Yount, Kathryn M.; Krause, Kathleen H.; VanderEnde, Kristin E.

Economic coercion refers to behaviors that control an intimate partner’s ability to acquire, use, and maintain economic resources. Little is known about economic coercion in Vietnam. Using survey responses from 533 married women ages 18–50 years, we estimated multinomial logistic regression models to compare the determinants of exposure to economic coercion only, co-occurring economic coercion and any psychological, physical, or sexual intimate partner violence (IPV), and any IPV only, relative to no exposure. Women who, in their childhood, witnessed physical IPV against their mother had higher odds of exposure to co-occurring economic coercion and any IPV as an adult (aOR = 3.54, 95% CI 1.84–6.83) and any IPV only (aOR = 1.75, 95% CI 1.00–3.06), but not economic coercion only. Women who experienced violence as a child had higher odds of exposure to any IPV only (aOR =1.63, 95% CI 1.04–2.56) but not economic coercion only. Women with more schooling had higher odds of exposure to economic coercion only (aOR = 1.17, 95% CI 1.03–1.33) but not other forms of violence. Overall, the estimates from the three models differed significantly. Thus, the determinants of economic coercion and common forms of IPV may differ. More research should focus on men’s perpetration of economic coercion. PMID:25948643

If effective interventions are to be used to address child mortality and malnutrition, then it is important that we understand the different pathways operating within the framework of child health. More attention needs to be given to understanding the contribution of social influences such as intimate partner violence (IPV). To investigate the relationship between maternal exposure to IPV and child mortality and malnutrition using data from five developing countries. Population data from Egypt, Honduras, Kenya, Malawi and Rwanda were analysed. Logistic regression analysis was used to generate odds ratios of the associations between several categories of maternal exposure to IPV since the age of 15 and three child outcomes: under-2-year-old (U2) mortality and moderate and severe stunting (<-2 Z-score height-for-age and <-3 Z-score height-for-age) in 6-59-month-old children. Analyses were adjusted for potential confounders, and the role of mediating factors was explored. The prevalence of physical and/or sexual IPV since the age of 15 years ranged from 15.5% (Honduras) to 46.2% (Kenya). For child stunting, prevalence ranged from 25.4% (Egypt) to 58.0% (Malawi) and for U2 mortality from 3.6% (Honduras) to 15.2% (Rwanda). In Kenya, maternal exposure to IPV was associated with higher U2 mortality (adjusted odds ratio (OR)=1.42, 95% CI 1.18 to 1.71) and child stunting (adjusted OR=1.36, 95% CI 1.16 to 1.61). In Malawi and Honduras, marginal associations were observed between IPV and severe stunting and U2 mortality, respectively, with strength of associations varying by type of violence. The relationship between IPV and U2 mortality and stunting in Kenya, Honduras and Malawi suggests that, in these countries, IPV plays a role in child malnutrition and mortality. This contributes to a growing body of evidence that broader public health benefits may be incurred if efforts to address IPV are incorporated into a wider range of maternal and child health programmes; however, the authors highlight the need for more research that can establish temporality, use data collected on the basis of the study's objectives, and further explore the causal framework of this relationship using more advanced statistical analysis.

This study sought to establish the prevalence and correlates of intimate partner violence (IPV) victimization in the 6 months before and after Hurricane Katrina. Participants were 445 married or cohabiting persons who were living in the 23 southernmost counties of Mississippi at the time of Hurricane Katrina. Data for this study were collected as part of a larger, population-based, representative study. The percentage of women reporting psychological victimization increased from 33.6% prior to Hurricane Katrina to 45.2% following Hurricane Katrina (p < .001). The percentage of men reporting psychological victimization increased from 36.7% to 43.1% (p = .01). Reports of physical victimization increased from 4.2% to 8.3% for women (p = .01) but were unchanged for men. Significant predictors of post-Katrina victimization included pre-Katrina victimization, age, educational attainment, marital status, and hurricane-related stressors. Reports of IPV were associated with greater risk of post-Katrina depression and posttraumatic stress disorder. Data from the first population-based study to document IPV following a large-scale natural disaster suggest that IPV may be an important but often overlooked public health concern following disasters.

To assess the prevalence and risk factors for intimate-partner violence (IPV) in women who attended a Family Medicine Unit in Tijuana, Mexico. A total of 297 women were interviewed and evaluated using two validated scales: violence and severity index and family APGAR to assess family functioning and IPV respectively. The mean age (± SD) was 40.6±13.8 years, and 120 (40.4%) women had suffered IPV: 47 (15.8%) psychological violence; 31 (10.4%) sexual violence; 77 (25.9%) physical violence, and in 19 (6.4%) there were actions that threatened the lives of women. The most common causes of domestic violence were women who reported that their partner had been jealous, or suspicion from friends (37.4%). Twenty two (7.4%) of the women with domestic violence reported that they had sought help. The prevalence of IPV was high and associated with the education level of the couple and family functioning.

Background The growth of the Internet has led to significant change and has become an integral part of modern life. It has made life easier and provided innumerous benefits; however, excessive use has brought about the potential for addiction, leading to severe impairments in social, academic, financial, psychological, and work domains. Individuals addicted to the Internet usually have comorbid psychiatric disorders. Panic disorder (PD) and generalized anxiety disorder (GAD) are prevalent mental disorders, involving a great deal of damage in the patient’s life. Objective This open trial study describes a treatment protocol among 39 patients with anxiety disorders and Internet addiction (IA) involving pharmacotherapy and modified cognitive behavioral therapy (CBT). Methods Of the 39 patients, 25 were diagnosed with PD and 14 with GAD, in addition to Internet addiction. At screening, patients responded to the MINI 5.0, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Clinical Global Impressions Scale, and the Young Internet Addiction Scale. At that time, IA was observed taking into consideration the IAT scale (cutoff score above 50), while anxiety disorders were diagnosed by a psychiatrist. Patients were forwarded for pharmacotherapy and a modified CBT protocol. Psychotherapy was conducted individually, once a week, over a period of 10 weeks, and results suggest that the treatment was effective for anxiety and Internet addiction. Results Before treatment, anxiety levels suggested severe anxiety, with an average score of 34.26 (SD 6.13); however, after treatment the mean score was 15.03 (SD 3.88) (P<.001). A significant improvement in mean Internet addiction scores was observed, from 67.67 (SD 7.69) before treatment, showing problematic internet use, to 37.56 (SD 9.32) after treatment (P<.001), indicating medium Internet use. With respect to the relationship between IA and anxiety, the correlation between scores was .724. Conclusions This study is the first research into IA treatment of a Brazilian population. The improvement was remarkable due to the complete engagement of patients in therapy, which contributed to the success of the treatment from a behavioral perspective, and gave patients the confidence to continue to manage Internet use in their lives.

The impact of inactivated polio vaccines (IPVs) on intestinal mucosal immune responses to live poliovirus is poorly understood. In a 2014 phase 2 clinical trial, Panamanian infants were immunized at 6, 10, and 14 weeks of age with bivalent oral polio vaccine (bOPV) and randomized to receive either a novel monovalent high-dose type 2-specific IPV (mIPV2HD) or a standard trivalent IPV at 14 weeks. Infants were challenged at 18 weeks with a monovalent type 2 oral polio vaccine (mOPV2). Infants' intestinal immune responses during the 3 weeks following challenge were investigated by measuring poliovirus type-specific neutralization and immunoglobulin (Ig) A, IgA1, IgA2, IgD, IgG, and IgM antibodies in stool samples. Despite mIPV2HD's 4-fold higher type 2 polio D-antigen content and heightened serum neutralization profile, mIPV2HD-immunized infants' intestinal immune responses to mOPV2 challenge were largely indistinguishable from those receiving standard IPV. Mucosal responses were tightly linked to evidence of active infection and, in the 79% of participants who shed virus, robust type 2-specific IgA responses and stool neutralization were observed by 2 weeks after challenge. Enhancing IPV-induced serum neutralization does not substantively improve intestinal mucosal immune responses or limit viral shedding on mOPV2 challenge. NCT02111135. © The Author(s) 2018.

To determine if intimate partner violence (IPV) was associated with unintended pregnancy and pregnancy loss among married women in Pakistan. A retrospective analysis was conducted using nationally representative cross-sectional secondary data from women of reproductive age who were currently married and had participated in the domestic violence module of the 2012-13 Pakistan Demographic and Heath Survey. Unintended pregnancy and pregnancy loss were defined as any mistimed or unwanted pregnancy, and any pregnancy that resulted in spontaneous abortion, induced abortion, or stillbirth, respectively. Associations with IPV were assessed by calculating adjusted odds ratios using logistic regression models. Data from 3518 individuals were included. Pregnancy loss had been experienced by 1282 (36.4%) participants and unintended pregnancy was reported by 391 (19.5%) of 2005 individuals this information was available for. In total, 1335 (37.9%) participants reported having ever experienced any form of IPV, including 919 (26.1%), 1112 (31.6%), and 697 (19.8%) participants who had experienced physical, emotional, and both emotional and physical IPV. Significant associations were observed between participants experiencing either physical or emotional IPV, emotional IPV, and both emotional and physical IPV, and unintended pregnancy (P=0.017, P<0.001, and P=0.011, respectively) and pregnancy loss (P=0.002, P=0.005, and P<0.001, respectively). There is an urgent need to develop preventive strategies to reduce intramarital IPV and its associated poor health outcomes. Copyright © 2015 International Federation of Gynecology and Obstetrics.

Intimate partner violence (IPV) is a public health problem worldwide. Several factors have been found to be associated with an increased prevalence of IPV, such as substance use. A cross-sectional study was conducted with the aim of determining the prevalence of IPV among women entering Hospital del Mar (Barcelona) for any medical/surgical reason, and who had a diagnosis of substance use disorder. Secondly, it was intended to psychometrically validate the Spanish version of the Hurt, Insulted, Threatened with Harm, Screamed (HITS) questionnaire. All patients were assessed by two IPV questionnaires, the Composite Abuse Scale (CAS) and HITS. Out of 52 patients interviewed, 46 answered both questionnaires. According to the CAS questionnaire, 23 patients (50%) experienced IPV at some point in their lives and 11 (23.9%) in the last year. Cannabis consumption was also associated with an increased severity of IPV (95% CI 3.5-28.9, p = .013).According to the HITS questionnaire, there was a prevalence of 39.1% (18 patients) in the last 12 months. HITS had a specificity of 100% and a sensitivity of 78% relative to the CAS questionnaire. A cut-off score x∈ [6.7], derived through ROC analysis, correctly discriminated 91% of the victims and 100% of the non-victims. The results obtained showed that the prevalence of IPV was very high among women who suffered from more than one substance use disorder. Therefore, it is highly recommended to systematically screen for IPV victimization by putting the HITS questionnaire into practice.

The production of Sabin inactivated poliovirus vaccine (IPV) can reduce biosafety requirements in the posteradication/post-oral poliovirus vaccine (OPV) era. We conducted a phase II, randomized, positive-controlled trial to assess the safety and immunogenicity of Sabin IPV. The test groups (A, B, and C) received 3 doses of high, middle, and low D antigen (D Ag) of Sabin IPV at ages 2, 3, and 4 months, respectively. Infants in 2 control groups, group D and group E, received 3 doses of trivalent OPV and conventional IPV (cIPV), respectively, on the same schedule as that of groups A, B, and C. Serum samples were collected before and 30 days after the administration of the third dose. In total, 500 infants were randomly assigned to 5 groups, and 449 infants completed the vaccine series. No serious adverse events were associated with vaccinations. After 3 doses, the seroconversion rates in groups A, B, C, D, and E were 100%, 97.8%, 96.6%, 100%, and 90.1%, respectively, for type 1 poliovirus; 97.7%, 95.7%, 78.7%, 100%, and 90.1%, respectively, for type 2; and 98.8%, 98.9%, 93.3%, 100%, and 97.8%, respectively, for type 3. Sabin IPV has good safety characteristics. The seroconversion rates for type 1 poliovirus (most appropriate concentration, 15 D Ag units [DU]), type 2 (32 DU), and type 3 (45 DU) Sabin IPV were similar to those of the OPV and cIPV control groups. NCT01056705.

Abstract Background The impact of inactivated polio vaccines (IPVs) on intestinal mucosal immune responses to live poliovirus is poorly understood. Methods In a 2014 phase 2 clinical trial, Panamanian infants were immunized at 6, 10, and 14 weeks of age with bivalent oral polio vaccine (bOPV) and randomized to receive either a novel monovalent high-dose type 2–specific IPV (mIPV2HD) or a standard trivalent IPV at 14 weeks. Infants were challenged at 18 weeks with a monovalent type 2 oral polio vaccine (mOPV2). Infants’ intestinal immune responses during the 3 weeks following challenge were investigated by measuring poliovirus type-specific neutralization and immunoglobulin (Ig) A, IgA1, IgA2, IgD, IgG, and IgM antibodies in stool samples. Results Despite mIPV2HD’s 4-fold higher type 2 polio D–antigen content and heightened serum neutralization profile, mIPV2HD-immunized infants’ intestinal immune responses to mOPV2 challenge were largely indistinguishable from those receiving standard IPV. Mucosal responses were tightly linked to evidence of active infection and, in the 79% of participants who shed virus, robust type 2–specific IgA responses and stool neutralization were observed by 2 weeks after challenge. Conclusions Enhancing IPV-induced serum neutralization does not substantively improve intestinal mucosal immune responses or limit viral shedding on mOPV2 challenge.

Greater access to alcohol has been widely found to be associated with many negative outcomes including violence perpetration. This study examines the relationship between alcohol outlet density, alcohol use, and intimate partner violence (IPV) victimization among young women in the United States. A direct association between alcohol outlet density in one's neighborhood and the likelihood of IPV victimization was examined. Data were from Wave III of the National Longitudinal Study of Adolescent Health (Add Health), which followed a nationally representative sample of adolescents into adulthood. Participants were young adult females age 18 to 26 at Wave III. Of the 4,571 female respondents who reported a current heterosexual relationship and had IPV data, 13.2% reported having been the victim of physical violence only and 6.5% experienced sexual only or physical and sexual violence in the relationship during the past year. In the regression models tested, there was no significant direct association between neighborhood alcohol outlet density and IPV victimization nor was there an association between outlet density and drinking behaviors, thus eliminating the possibility of an indirect association. Results of fully adjusted models indicate females who drank heavily, whether infrequently or frequently, were at significant risk for experiencing sexual only IPV or sexual and physical IPV. Asians and Native Americans were at significantly greater odds of experiencing sexual only or sexual and physical IPV compared with non-Hispanic Whites, while non-Hispanic Blacks were at significantly greater odds for physical only IPV. We conclude that a continuous measure of alcohol outlet density was not associated with IPV in models controlling for individual and other neighborhood characteristics. Young women who drink heavily, whether infrequently or frequently, have greater odds of experiencing sexual only or sexual and physical compared to abstainers. Similar to previous study findings, young women living with or married to their partner were at far greater risk of experiencing physical only and/or sexual only or sexual and physical IPV. The study adds to the growing body of literature that examines how community characteristics such as outlet density influence the likelihood of IPV.

Husbands' alcohol use has been associated with family-level stress and intimate partner violence (IPV) against women in India. Joint family systems are common in India and IPV often co-occurs with non-violent family maltreatment of wives (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care). Alcohol use increases for some parents following the birth of a child. This study examined 1,038 postpartum women's reports of their husbands' alcohol use and their own experiences of IPV (by husband) and non-violent maltreatment from husbands and/or in-laws. We analyzed cross-sectional, quantitative data collected in 2008, from women (ages 15-35) seeking immunizations for their infants <6 months at three large urban health centers in Mumbai, India. Crude and adjusted logistic regression models estimated associations between the independent variable (husbands' past month use of alcohol) and two dependent variables (postpartum IPV and maltreatment). Overall, 15% of husbands used alcohol, ranging from daily drinkers (10%) to those who drank one to two times per week (54%). Prevalence of postpartum IPV and family maltreatment was 18% and 42%, respectively. Prevalence of IPV among women married to alcohol users was 27%. Most abused women's husbands always (27%) or sometimes (37%) drank during violent episodes. Risk for IPV increased with a man's increasing frequency of consumption. Women who lived with a husband who drank alcohol, relative to non-drinkers, were more likely to report postpartum IPV, aOR = 2.0, 95% confidence interval (CI) = [1.3, 3.1]. Husbands' drinking was marginally associated with increased risk for family maltreatment, aOR = 1.4, 95% CI = [1.0, 2.1]. Our findings suggest that men's alcohol use is an important risk factor for postpartum IPV and maltreatment. Targeted services for Indian women contending with these issues are implicated. Postpartum care offers an ideal opportunity to screen for IPV, household maltreatment, and other health risks, such as husband's use of alcohol. There is need to scale up proven successful interventions for reducing men's alcohol use and design strategies that provide at-risk women protection from alcohol-related IPV.

Intimate partner violence (IPV) has been shown to be associated with higher rates of HIV infection among women, underscoring the importance of encouraging IPV victims to receive HIV testing. However, we do not know how much HIV testing behavior is influenced by IPV victimization. The current study characterized the association between individual types of IPV and HIV testing in a large sample of non-pregnant women in 15 US states/territories. The 2005 Behavioral Risk Factor Surveillance System data were analyzed after restricting the sample to non-pregnant women. The dependent variable, whether a woman ever had an HIV test, was examined in relation to individual types of IPV victimization (threatened physical violence; attempted physical violence; completed physical violence; and unwanted sex). Associations between HIV testing and types of IPV were assessed using adjusted risk ratios (aRR) that controlled for demographics and HIV-related risk factors (intravenous drug use, sexually transmitted diseases, exchange sex, unprotected anal sex). Approximately 28.6 % of women reported ever having experienced IPV, and 52.8 % of these women reported being tested for HIV. Among women who had not experienced IPV, 32.9 % reported ever having been tested for HIV. HIV testing was associated with lifetime experience of threatened violence (aRR = 1.43; 95 % CI = 1.24-1.65), attempted violence (aRR = 1.43; 95 % CI = 1.20-1.69), completed physical violence (aRR = 1.30; 95 % CI = 1.13-1.48), and unwanted sex (aRR = 1.66; 95 % CI = 1.48-1.86). Women who experienced each type of IPV were more likely to have been ever tested for HIV compared to women with no IPV history. However, nearly half of those reporting IPV, even though at greater risk for HIV infection, had never been tested. Additional efforts are needed to address barriers to testing in this group.
Mental ill health in structural pathways to women's experiences of intimate partner violence.

Depression, post-traumatic stress disorder (PTSD), and binge drinking are among mental health effects of child abuse and intimate partner violence (IPV) experiences among women. Emerging data show the potential mediating role of mental ill health in the relationship of child abuse and IPV. There is evidence that PTSD, depression and alcohol abuse are comorbid common mental disorders and that a bidirectional relationship exists between depression and IPV in some settings. Furthermore, the temporal direction in the relationship of alcohol abuse and women's IPV experiences from different studies is unclear. We undertook a study with women from the general population to investigate the associations of child abuse, mental ill health and IPV; and describe the underlying pathways between them. Data is from a household survey employing a multi-stage random sampling approach with 511 women from Gauteng, South Africa. IPV was measured using the WHO Multi-country Study on Women's Health and Domestic Violence Questionnaire. Child abuse was measured using a short form of the Childhood Trauma Questionnaire. Depression was measured using the Centre for Epidemiologic Studies Depression Scale (CESD). PTSD symptoms were measured using the Harvard Trauma Questionnaire. Binge drinking was measured using the Alcohol Use Disorders Identification Test (AUDIT) scale. All data analyses were conducted in Stata 13. Regression modelling was used to test the association between variables. Structural equation modelling with full information maximum likelihood estimation accounting for missing data was done to analyse the underlying pathways between variables. Fifty percent of women experienced IPV in their lifetime and 18% experienced IPV in the 12 months before the survey. Twenty three percent of women were depressed, 14% binge drank and 11.6% had PTSD symptoms. Eighty six percent of women had experienced some form of child abuse. Sociodemographic factors associated with recent IPV in multivariate models were younger age and foreign nationality. Depression, PTSD and binge drinking mediated the relationship of child abuse and recent IPV. Depression, PTSD and binge drinking were also effects of recent IPV. Other factors associated with recent IPV experience included relationship control, having a partner who regularly consumed alcohol and experiencing other life traumatic experiences. Mental ill health plays a mediating role in the relationship of child abuse and recent IPV experiences among women. Conversely, IPV also negatively affects women's mental health. Interventions to reducing the incidence of IPV could help alleviate the burden of mental ill health among women and vice versa. Effective integration of mental health services in primary health care, detection of symptoms, brief interventions and strengthened referral mechanisms for sustained community-based care are necessary in responding to victims of intimate partner violence. Response for abused children needs to take similar approaches and reduce the long-term mental health effects associated with violent exposures.

Concomitant administration of bivalent rLP2086 (Trumenba [Pfizer, Inc] and diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine (DTaP/IPV) was immunologically noninferior to DTaP/IPV and saline and was safe and well tolerated. Bivalent rLP2086 elicited robust and broad bactericidal antibody responses to diverse Neisseria meningitidis serogroup B strains expressing antigens heterologous to vaccine antigens after 2 and 3 vaccinations. Bivalent rLP2086, a Neisseria meningitidis serogroup B (MnB) vaccine (Trumenba [Pfizer, Inc]) recently approved in the United States to prevent invasive MnB disease in individuals aged 10-25 years, contains recombinant subfamily A and B factor H binding proteins (fHBPs). This study evaluated the coadministration of Repevax (diphtheria, tetanus, and acellular pertussis and inactivated poliovirus vaccine [DTaP/IPV]) (Sanofi Pasteur MSD, Ltd) and bivalent rLP2086. Healthy adolescents aged ≥11 to <19 years received bivalent rLP2086 + DTaP/IPV or saline + DTaP/IPV at month 0 and bivalent rLP2086 or saline at months 2 and 6. The primary end point was the proportion of participants in whom prespecified levels of antibodies to DTaP/IPV were achieved 1 month after DTaP/IPV administration. Immune responses to bivalent rLP2086 were measured with serum bactericidal assays using human complement (hSBAs) against 4 MnB test strains expressing fHBP subfamily A or B proteins different from the vaccine antigens. Participants were randomly assigned to receive bivalent rLP2086 + DTaP/IPV (n = 373) or saline + DTaP/IPV (n = 376). Immune responses to DTaP/IPV in participants who received bivalent rLP2086 + DTaP/IPV were noninferior to those in participants who received saline + DTaP/IPV.The proportions of bivalent rLP2086 + DTaP/IPV recipients with prespecified seroprotective hSBA titers to the 4 MnB test strains were 55.5%-97.3% after vaccination 2 and 81.5%-100% after vaccination 3. The administration of bivalent rLP2086 was well tolerated and resulted in few serious adverse events. Immune responses to DTaP/IPV administered with bivalent rLP2086 to adolescents were noninferior to DTaP/IPV administered alone. Bivalent rLP2086 was well tolerated and elicited substantial and broad bactericidal responses to diverse MnB strains in a high proportion of recipients after 2 vaccinations, and these responses were further enhanced after 3 vaccinations.ClinicalTrials.gov identifier NCT01323270. © The Author 2016.

OBJECTIVE To investigate the prevalence of violence involving intimate partners among women visiting Canadian family practices and to assess participants’ attitudes toward future use of computer-assisted screening for violence and other health risks. DESIGN Self-report via written survey. SETTING Group family practice clinic in inner-city Toronto, Ont. PARTICIPANTS Women patients at least 18 years old who were fluent in English. MAIN OUTCOME MEASURES Responses to questions about violence selected from the Abuse Assessment Screen and the Partner Violence Screen. Participants’ attitudes toward computer-assisted screening as measured by the Computerized Lifestyle Assessment Scale (1 to 5) in the domains of benefits, privacy—barriers, interaction—barriers, and interest. RESULTS Responses were received from 202 patients, 144 of whom were in current or recent relationships and completed the section on intimate-partner violence (IPV). The overall prevalence of IPV in current or recent relationships was 14.6%. Emotional abuse was reported by 10.4%, threat of violence by 8.3%, and physical or sexual violence by 7.6% of respondents. Emotional abuse was significantly associated with threat of violence and physical or sexual violence (P≤.001). Analysis of responses to questions on computerized screening revealed that participants generally perceived it would have benefits (mean score 3.6) and were very interested in it (mean score 4.3). Those who reported experiencing IPV rated the benefits of computerized screening significantly higher than respondents without IPV experiences did (t2.3, df142, P < .05). Participants were “not sure” about barriers (mean score 3.0). Responses were similar in the 2 groups for the domains of interest, privacy—barriers, and interaction—barriers. CONCLUSION The high rate of IPV reported by women attending family practices calls for physicians to be vigilant. Future research should examine ways to facilitate physicians’ inquiry into IPV. The positive attitudes of our participants toward interactive computer-assisted screening indicates a need for more research in this area. PMID:17872682
Intimate Partner Violence Experienced by Physicians: A Review.

Physicians play a significant role in screening for domestic violence. However, little information is available about the prevalence of physicians who experience intimate partner violence (IPV) or the implications for their clinical practice. National surveys indicate a potential prevalence of 16% for sexual abuse and 32% for abuse by an intimate partner. This extrapolates to more than 395,000 potential physician victims, the majority of which are women. We conducted a systematic review of IPV and physician victims from 1990 to 2014 that included peer-reviewed journals, trade books, and dissertations that referenced physician victims. We identified 17 publications; nine quantitative studies, four first-person accounts, one qualitative study, and a qualitative dissertation that included two physician subjects. Two case studies of victimized physicians were identified in trade books. Quantitative results noted that women reported higher prevalence for all experiences of violence [childhood exposure (6%-32%), adult IPV exposure (7%-24%)] than men (6%-10%). This review highlights the need for improved understanding of physician experience with IPV, and development of physician-sensitive resources and treatment approaches. Contributions and limitations are provided for each publication. IPV exposure impacts clinical practice, including reticence to consistently screen patients. Lower reported prevalence may be related to extreme stigma among physicians that may prevent their reporting and help seeking, but more research is needed. We provide recommendations for clinical practice, education, and future research.

Intimate partner violence (IPV) is a worldwide health concern and an important risk factor for poor mental/physical health in both women and men. Little is known about whether IPV leads to sleep disturbance. However, sleep problems may be common in the context of IPV and may mediate relationships with mental/physical health. Data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS) were used (N = 34,975). IPV was assessed in female and male participants for any history of being threatened by, physically hurt by, or forced to have sex with an intimate partner (THREAT, HURT, and SEX, respectively), and, further, as being forced to have sex with or physically injured by an intimate partner within the past year (SEXyr and HURTyr, respectively). These survey items were coded yes/no. Sleep disturbance was assessed as difficulty falling asleep, staying asleep, or sleeping too much at least 6 of the last 14 days. Logistic regression analyses, adjusted for age, sex, race, income, education, and physical/mental health, assessed whether IPV predicted sleep disturbance. Sobel-Goodman tests assessed whether relationships between IPV and physical/mental health were partially mediated by sleep disturbance. All IPV variables were associated with sleep disturbance, even after adjusting for the effects of age, sex, race/ethnicity, income, education, employment, marital status, physical health and mental health. THREAT was associated with sleep disturbance (odds ratio [OR] = 2.798, p < .0001), as was HURT (OR = 2.683, p < .0001), SEX (OR = 3.237, p < .0001), SEXyr (OR = 7.741, p < .0001), and HURTyr (OR = 7.497, p < .0001). In mediation analyses, all IPV variables were associated with mental health (p < .0001), and all were associated with physical health (p < .007) except SEXyr. Sleep disturbance partially mediated all relationships (Sobel p < .0005 for all tests). Mediation was around 30%, ranging from 18% (HURTyr and mental health) to 41% (HURT and physical health). IPV was strongly associated with current sleep disturbance above the effect of demographics and overall mental/physical health, even if the IPV happened in the past. Furthermore, sleep disturbance partially mediates the relationship between IPV and mental/physical health. Sleep interventions may potentially mitigate negative effects of IPV. © The Author(s) 2015.

Entanglement percolation on a quantum internet with scale-free and clustering characters
DOE Office of Scientific and Technical Information (OSTI.GOV)
Wu Liang; Zhu Shiqun
The applicability of entanglement percolation protocol to real Internet structure is investigated. If the current Internet can be used directly in the quantum regime, the protocol can provide a way to establish long-distance entanglement when the links are pure nonmaximally entangled states. This applicability is primarily due to the combination of scale-free degree distribution and a high level of clustering, both of which are widely observed in many natural and artificial networks including the current Internet. It suggests that the topology of real Internet may play an important role in entanglement establishment.

Links between intimate partner violence (IPV) and gambling problems are under researched in general population samples. Understanding these relationships will allow for improved identification and intervention. We investigated these relationships and sought to determine whether links were attenuated by axis I and II disorders. This study examined data from waves 1 and 2 (N = 25,631) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC); a nationally representative survey of U.S. adults. Gambling symptoms and other psychiatric disorders were measured at wave 1 by the Alcohol Use Disorder and Associated Disability Interview Schedule-DSM-IV Version (AUDADIS-IV). Physical IPV victimization and perpetration in the last 12 months were assessed 3 years later at wave 2 using items from the Conflict Tactics Scale-R. Binary logistic regression models were used to examine associations separately for males and females. Problem gambling was associated with increased odds of both IPV perpetration for males (OR = 2.62, 95%CI = 1.22-5.60) and females (OR = 2.87, 95%CI = 1.29-6.42), and with IPV victimization for females only (OR = 2.97, 95%CI = 1.31-6.74). Results were attenuated with inclusion of axis I and axis II disorders; links between gambling and IPV were weaker than those involving other mental health conditions. There are prospective associations with gambling problems and physical IPV which have implications for identification, spontaneous disclosure, and treatment seeking. The links between gambling problems and violence are complex and should not be considered independently of co-occurring mental health and substance use disorders.

There is little information on the private lives of women engaged in sex work, particularly how power dynamics within intimate relationships may affect intimate partner violence (IPV). Using baseline data of sex workers enrolled in a longitudinal cohort, ‘AESHA’ (An Evaluation of Sex Workers’ Health Access), the present study examined the association between sexual relationship power and IPV among sex workers in non-commercial partnerships in Vancouver, Canada. Pulweritz's Sexual Relationship Power Scale (SRPS) and The World Health Organization (WHO) Intimate Partner Violence Against Women scale (Version9.9) were used. Bivariate and multivariate logistic regression techniques were used to investigate the potential confounding effect of sexual relationship power on IPV among sex workers. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were reported. Of 510 sex workers, 257 (50.4%) reported having an non-commercial intimate partner and were included in this analysis. In the past 6 months, 84 (32.7%) sex workers reported IPV (physical, sexual or emotional). The median age was 32 years, 39.3% were of Aboriginal ancestry, and 27.6% were migrants. After controlling for known confounders (e.g., age, Aboriginal ancestry, migrant status, childhood trauma, non-injection drug use), low relationship power was independently associated with 4.19 increased odds (95% CI: 1.93-9.10) and medium relationship power was associated 1.95 increased odds (95% CI:0.89-4.25) of IPV. This analysis highlights how reduced control over sexual-decision making is plays a critical role in IPV among sex workers, and calls for gender-focused and coupled-based interventions tailored to noncommercial intimate partnerships of sex workers.

Background Despite widespread apartheid-related human rights violations (HRV) and intimate partner violence (IPV) in South Africa, research investigating the influence of HRV on IPV perpetration is scarce. Methods This study analysed data from the South Africa Stress and Health Study, a cross-sectional survey conducted from 2003 to 2004 with 4351 South Africans examining public health concerns associated with apartheid. Analyses were restricted to men who had ever been married or had ever cohabited with a female partner. Logistic regression was used to examine associations between experiences of HRV and lifetime physical IPV perpetration. Results A total of 772 South Africa men met the study criteria (389 liberation supporters and 383 government supporters). Adjusted logistic regression analyses indicated that among liberation supporters, a significant association existed between experiencing major HRV (AOR 2.40, 95% CI 1.20 to 4.81), custody-related HRV (AOR 6.61, 95% CI 2.00 to 21.83), victimisation of close friends/family members (AOR 3.38, 95% CI 1.26 to 9.07) and physical IPV perpetration. Among government supporters, a significant association was observed between experiencing HRV (AOR 2.99, 95% CI 1.34 to 6.65) and victimisation of close friends/immediate family (AOR 5.42, 95% CI 1.44 to 19.02) and IPV perpetration. Conclusion This work indicates the importance of men’s experiences with HRV with regard to IPV perpetration risk. Future work is needed to understand the mechanisms underlying the observed relationships, particularly regarding mental health and gender norms as suggested by current literature, in order to inform interventions in South Africa and other regions affected by politically motivated conflict.

Adjusted logistic regression analyses indicated that among liberation supporters, a significant association existed between experiencing major HRV (AOR 2.40, 95% CI 1.20 to 4.81), custody-related HRV (AOR 6.61, 95% CI 2.00 to 21.83), victimisation of close friends/family members (AOR 3.38, 95% CI 1.26 to 9.07) and physical IPV perpetration. Among government supporters, a significant association was observed between experiencing HRV (AOR 2.99, 95% CI 1.34 to 6.65) and victimisation of close friends/immediate family (AOR 5.42, 95% CI 1.44 to 19.02) and IPV perpetration. This work indicates the importance of men's experiences with HRV with regard to IPV perpetration risk. Future work is needed to understand the mechanisms underlying the observed relationships, particularly regarding mental health and gender norms as suggested by current literature, in order to inform interventions in South Africa and other regions affected by politically motivated conflict.

There is little information on the private lives of women engaged in sex work, particularly how power dynamics within intimate relationships may affect intimate partner violence (IPV). Using baseline data of sex workers enrolled in a longitudinal cohort, "An Evaluation of Sex Workers' Health Access" (AESHA), the present study examined the association between sexual relationship power and IPV among sex workers in non-commercial partnerships in Vancouver, Canada. Pulweritz's Sexual Relationship Power Scale (SRPS) and The World Health Organization (WHO) Intimate Partner Violence against Women Scale (Version9.9) were used. Bivariable and multivariable logistic regression techniques were used to investigate the potential confounding effect of sexual relationship power on IPV among sex workers. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were reported. Of 510 sex workers, 257 (50.4%) reported having an non-commercial intimate partner and were included in this analysis. In the past 6 months, 84 (32.7%) sex workers reported IPV (physical, sexual or emotional). The median age was 32 years, 39.3% were of Aboriginal ancestry, and 27.6% were migrants. After controlling for known confounders (e.g., age, Aboriginal ancestry, migrant status, childhood trauma, non-injection drug use), low relationship power was independently associated with 4.19 increased odds (95% CI: 1.93-9.10) and medium relationship power was associated 1.95 increased odds (95% CI: 0.89-4.25) of IPV. This analysis highlights how reduced control over sexual-decision making is plays a critical role in IPV among sex workers, and calls for innovation and inclusive programming tailored to sex workers and their non-commercial intimate partnerships.

Brief Internet interventions have been shown to reduce alcohol consumption. This trial intended to compare the effects of one such brief intervention to an extended Internet intervention for problem drinkers. Using online advertising, 490 participants, 18 years or older, were recruited and randomized to receive a brief ( CheckYourDrinking.net ) versus an extended ( AlcoholHelpCentre.net ) Internet intervention and were followed up at 6, 12, and 24 months. The per protocol primary analysis assessed difference between condition at the 12-month follow-up. The follow-up rate at 12 months was 83.3 %. ANCOVAs of the primary (Alcohol Use Disorder Identification Test (AUDIT)-C) and secondary outcome variables (drinks in a typical week, highest number of drinks on one occasion-baseline drinking as covariate) revealed no significant (p > 0.05) differences between the interventions. Similarly, combined analyses of the 6-, 12-, and 24-month follow-up revealed no significant differences between interventions at all time points. The present study does not provide support for the added benefit of an extended Internet intervention for problem drinkers over a brief Internet intervention.

Children exposed to intimate partner violence (IPV) are at increased risk for developing traumatic stress symptoms and posttraumatic stress disorder (PTSD). Unfortunately, children who witness IPV are often exposed to additional traumatic events. Previous research has indicated that approximately one third of children experience 2 or more direct victimizations each year, and that exposure to one type of victimization places children at risk for exposure to additional types of victimization. Yet little is known about the impact of these additional traumas on children's functioning. For a sample of 120 preschool children (age 4-6 years) exposed to IPV in the past 2 years, 38% were exposed to additional traumatic events, including sexual assaults by family members, physical assaults, serious accidents, and/or life-threatening illnesses. Those exposed to both IPV and additional traumatic events had higher rates of PTSD diagnoses, traumatic stress symptoms (d = 0.96), and internalizing (d = 0.86) and externalizing behavior (d = 0.47) problems, than those exposed to IPV alone. We also compared DSM-IV diagnostic criteria to proposed criteria for evaluating traumatic stress in preschool-aged children. Results revealed the importance of conducting a complete assessment of traumatic events prior to treating children exposed to IPV. Copyright © 2012 International Society for Traumatic Stress Studies.
A Security Analysis on Kempf-Koodli's Security Scheme for Fast Mobile IPv6
NASA Astrophysics Data System (ADS)
You, Ilsun; Sakurai, Kouichi; Hori, Yoshiaki
Recently, the security scheme, proposed by Kempf and Koodli, has been adopted as a security standard for Fast handover for Mobile IPv6. But, it does not prevent denial of service attacks while resulting in high computation cost. More importantly, we find that it is still vulnerable to redirection attacks because it fails to secure the Unsolicited Neighbor Advertisement messages. In this paper, Kempf-Koodli's scheme is formally analyzed through BAN-logic and its weaknesses are demonstrated.

We describe the first use from space of the Bundle Protocol for Delay-Tolerant Networking (DTN) and lessons learned from experiments made and experience gained with this protocol. The Disaster Monitoring Constellation (DMC), constructed by Surrey Satellite Technology Ltd (SSTL), is a multiple-satellite Earth-imaging low-Earth-orbit sensor network in which recorded image swaths are stored onboard each satellite and later downloaded from the satellite payloads to a ground station. Store-and-forward of images with capture and later download gives each satellite the characteristics of a node in a disruption-tolerant network. Originally developed for the Interplanetary Internet, DTNs are now under investigation in an Internet Research Task Force (IRTF) DTN research group (RG), which has developed a bundle architecture and protocol. The DMC is technically advanced in its adoption of the Internet Protocol (IP) for its imaging payloads and for satellite command and control, based around reuse of commercial networking and link protocols. These satellites use of IP has enabled earlier experiments with the Cisco router in Low Earth Orbit (CLEO) onboard the constellation s UK-DMC satellite. Earth images are downloaded from the satellites using a custom IP-based high-speed transfer protocol developed by SSTL, Saratoga, which tolerates unusual link environments. Saratoga has been documented in the Internet Engineering Task Force (IETF) for wider adoption. We experiment with the use of DTNRG bundle concepts onboard the UK-DMC satellite, by examining how Saratoga can be used as a DTN convergence layer to carry the DTNRG Bundle Protocol, so that sensor images can be delivered to ground stations and beyond as bundles. Our practical experience with the first successful use of the DTNRG Bundle Protocol in a space environment gives us insights into the design of the Bundle Protocol and enables us to identify issues that must be addressed before wider deployment of the Bundle Protocol.

Attention-deficit/hyperactivity disorder (ADHD) is associated with interpersonal dysfunction during childhood and adolescence, yet little is known about the romantic relationships of young women with childhood ADHD. In the present study, we draw from a longitudinal sample of girls followed prospectively into young adulthood, comparing those with (n = 114) and without (n = 79; comparisons) childhood ADHD in terms of their risk for physical victimization by an intimate partner (physical IPV; e.g., slapping, punching) by 17–24 years of age. We examined ADHD both diagnostically and dimensionally, at the same time establishing reliable indicators of young adult physical IPV. Externalizing and internalizing problems, and academic achievement during adolescence, were tested as potential mediators. Overall, participants with a childhood diagnosis of ADHD experienced more physical IPV than did comparisons (30.7% vs. 6.3%). In parallel, IPV was associated with higher levels of childhood ADHD symptomatology (d = .73). Young women with persistent ADHD stood the highest risk of experiencing IPV (37.3%), followed by those with transient ADHD (19.0%) and those never-diagnosed (5.9%). Academic achievement measured during adolescence was a significant partial mediator of the childhood ADHD symptomatology-young adult IPV relationship, even with control of sociodemographic, psychiatric, and cognitive factors, including childhood reading and math disorders. Findings indicate that in young women, childhood ADHD is a specific and important predictor of physically violent victimization in their intimate relationships. This vulnerable population requires IPV prevention and intervention, with academic empowerment as a key target. PMID:25663589

Reducing violence against women is a global public health priority, particularly in low-income and conflict-affected societies. However, more needs to be known about the causes of intimate partner violence (IPV) in these settings, including the stress of bride price obligations. The representative study of women attending ante-natal clinics in Dili, Timor-Leste was conducted between June, 2013 and September, 2014 with 1672 pregnant women, a response rate of 96%. We applied contextually developed measures for the stress of bride price and poverty, and the World Health Organisation measure for intimate partner violence. Compared to those with no problems with bride price, women with moderate or serious problems with that custom reported higher rates of IPV (18.0% vs. 43.6%). Adjusting for socio-demographic factors, multivariate analysis revealed that ongoing poverty (OR = 1.75, 95% CI: 1.20-2.56) was significantly associated with IPV. Importantly, the strongest association with IPV was problems with bride price (OR = 2.73, 95% CI: 1.86-4.01). This is the first large consecutively sampled study to demonstrate a strong association between the stressors of bride price and poverty with IPV. Notably, bride price stress had the strongest association with IPV. Revealing this hitherto unrecognized factor of bride price stress may prove pivotal in guiding policy and interventions aimed at reducing IPV, and thereby improve the health and psychosocial status of women in low income and conflict-affected settings.

High levels of shear stress can prevent and disrupt Pseudomonas aeruginosa biofilm formation in vitro. Intrapulmonary percussive ventilation (IPV) could be used to introduce shear stress into the lungs of cystic fibrosis (CF) patients to disrupt biofilms in vivo. We performed a first-of-its-kind pilot clinical study to evaluate short-term IPV therapy at medium (200 bursts per minute, bpm) and high frequency (400 bpm) as compared to autogenic drainage (AD) on lung function and the behavior of P. aeruginosa in the CF lung in four patients who are chronically colonized by P. aeruginosa. A significant difference between the three treatment groups was observed for both the forced expiratory volume in 1 s (FEV1) and the forced vital capacity (FVC) (p < 0.05). More specifically, IPV at high frequency significantly increased FEV1 and FVC compared to AD (p < 0.05) and IPV at medium frequency (p < 0.001). IPV at high frequency enhanced the expression levels of P. aeruginosa planktonic marker genes, which was less pronounced with IPV at medium frequency or AD. In conclusion, IPV at high frequency could potentially alter the behavior of P. aeruginosa in the CF lung and improve lung function. The trail was retrospectively registered at the ISRCTN registry on 6 June 2013, under trial registration number ISRCTN75391385.

To determine whether households that generate several 911 calls differ in important ways from those that make a single call and to determine whether households that generate repeat 911 calls for intimate partner violence (IPV) experience more severe violence than those that do not. All cases of police-documented IPV were reviewed and linked with their respective 911 calls. Each incident report was reviewed to determine the relationship between the offender and victim, demographic characteristics of the offender and victim, weapon and substance involvement, prior incidents of IPV, and violence severity. Of the 1,505 IPV addresses identified during the 12-month study interval, 1,010 (67.1%) placed more than one phone call to report IPV. Sixty-nine percent of African American victims, 50.6% of white victims, and 36.8% of Hispanic victims were repeat callers (p < 0.001). There were no differences between addresses that generated repeat calls versus single calls with respect to offender alcohol or drug involvement, presence of children, victim age, or offender age. Sixty-seven percent of households with severe violence and 66.9% of households with minor violence generated repeat 911 calls (p = 0.98). Ethnic differences in 911 use for IPV exist between African Americans, whites, and Hispanics. However, unknown societal, economic, or cultural issues could have influenced this finding. Households that repeatedly contacted 911 during the study interval to report IPV were not more likely to experience severe violence than those that placed a single 911 call.

2009-01-01
A Delay-Tolerant Network (DTN) Architecture (Request for Comment, RFC-4838) and Bundle Protocol Specification, RFC-5050, have been proposed for space and terrestrial networks. Additional security specifications have been provided via the Bundle Security Specification (currently a work in progress as an Internet Research Task Force internet-draft) and, for link-layer protocols applicable to Space networks, the Licklider Transport Protocol Security Extensions. This document provides a security analysis of the current DTN RFCs and proposed security related internet drafts with a focus on space-based communication networks, which is a rather restricted subset of DTN networks. Note, the original focus and motivation of DTN work was for the Interplanetary Internet . This document does not address general store-and-forward network overlays, just the current work being done by the Internet Research Task Force (IRTF) and the Consultative Committee for Space Data Systems (CCSDS) Space Internetworking Services Area (SIS) - DTN working group under the DTN and Bundle umbrellas. However, much of the analysis is relevant to general store-and-forward overlays.

A substantial body of literature has documented the negative effects of intimate partner violence (IPV) on a wide range of children's developmental outcomes. However, whether a child's exposure to IPV leads to increased adjustment difficulties is likely to depend on a variety of factors, including the caregiver's mental health and the developmental time period when IPV exposure occurs. The present study seeks to improve our understanding of the long-term effects of IPV exposure and maternal depression on the development of children's overt aggressive behavior. Longitudinal analyses (i.e., latent growth curve modeling) examining three time points (toddler: age 2-3 years, preschool/kindergarten: age 4-5 years, and elementary school: age 6-8 years) were conducted using 1,399 at-risk children drawn from the National Survey of Child and Adolescent Well-Being (NSCAW-I). IPV exposure during age 2-3 years was significantly related to concurrent aggressive behavior and aggressive behavior during age 4-5 years. At all three time points, IPV was significantly associated with maternal depression, which in turn, was significantly related to higher levels of aggressive behavior. There was also a significant indirect lagged effect of IPV exposure at age 2-3 years through maternal depression on aggressive behavior at age 4-5 years. Results indicated that maternal depression was a strong predictor of increased reports of overt aggressive behavior, suggesting that interventions to buffer the effects of IPV exposure should focus on relieving maternal depression and fostering productive social behavior in children.

Adverse childhood experiences (ACEs) and intimate partner violence (IPV) are recognized global health problems. Both ACEs and IPV have been linked to adverse physical and mental health problems for both mothers and infants. The aim of this study was to determine the prevalence of physical and/or sexual ACEs and IPV and their association to symptoms of postpartum depression among postpartum women in sub-Saharan Africa. A cross-sectional survey was conducted in three health centers in the three districts of Dar es Salaam, comprising Ilala, Kinondoni and Temeke. A total of 500 women were interviewed by two trained midwife nurses during their routine postnatal care. The women were asked about their experiences of adverse childhood experiences, intimate partner violence and symptoms of postpartum depression. Of the 500 women who were interviewed, 39.4% (n = 197) reported to have experienced physical and/or sexual ACE and 18.8% (n = 94) experienced physical and/or sexual IPV during their index pregnancy. Physical ACE (AOR 2.6, 95% CI: 1.50-4.57), sexual ACE (AOR 2.7, 95% CI: 1.35-5.41), physical IPV (AOR 5.8, 95% CI: 2.98-11.43) and Sexual IPV (AOR 5.5, 95%CI: 2.51, 12.09) were significantly associated with symptoms of postpartum depression. Four out of ten women reported to have experienced ACEs and two out of ten women reported IPV in the index pregnancy which was significantly associated with symptoms of postpartum depression. These results are alarming and call upon the attention of health workers and the community at large in prevention, screening and early intervention of ACEs, IPV and symptoms of postpartum depression.

In this study, we examined intimate partner violence (IPV), cold violence, and controlling behaviors in male same-sex relationships in China, with a focus on the characteristics of IPV and controlling behaviors, and their relationships with ambivalent sexism. IPV was categorized as psychological aggression, physical injury, physical assault, and sexual coercion and was measured using the revised Conflict Tactics Scales (CTS2), an eight-item scale measuring cold violence that was designed specifically for this study. Controlling behaviors were measured using a 34-item scale that was designed for this study, and sexist attitudes toward women and men were assessed using the short forms of the Ambivalent Sexism Inventory (ASI) and the Ambivalence toward Men Inventory (AMI), respectively. Participants ( N = 272) reported instances of perpetration of or victimization by IPV and controlling behaviors within the past 6 months and indicated ambivalent sexism (hostile attitude toward men and women and benevolent attitude toward men and women [HM, HS, BM, and BS, respectively]). Almost 47.1% of the participants reported an experience of IPV, and the prevalence of cold violence and controlling behaviors was found to be 65.1% and 80.5%, respectively. Psychological aggression was the most common, followed sequentially by sexual coercion, physical assault, and injury in present study. We found a strong association between perpetration and victimization and that different forms of violence tend to co-occur in both IPV and controlling behaviors. As predicted, ambivalent sexism was positively correlated with IPV and controlling behaviors, specifically HS and HM. The results indicated the high prevalence of IPV and controlling behaviors among male same-sex relationships, and sexism contributing to this high prevalence.

Risk for unmet need for contraception is associated with men's perpetration of intimate partner violence (IPV) against women and may be influenced by violence perpetrated by other family members (family violence, FV). Women who married as minors may be most vulnerable to the potential compounding effect of IPV and FV on unmet need. Using nationally representative data from the 2012 Jordan Population and Family Health Survey we examined unmet need by exposure to IPV and FV by women's age at marriage (<18, 18+ years). Logistic regression was used to test whether IPV and FV were independently associated with unmet need, by age at marriage. Interaction terms (IPV×FV) were tested in both models. Stratification by FV was employed to clarify the interpretation of significant interactions. IPV increased the odds of unmet need by 87% [adjusted odds ratio (AOR) 1.87; 95% confidence interval (95% CI) 1.13-3.10] and 76% (AOR 1.76; 95% CI 1.30-2.38) among women who married prior to and after the age of 18 years, respectively. Women married as minors who experienced IPV and FV had a four-fold higher likelihood of having an unmet need (AOR 6.75; 95% CI 1.95-23.29) compared to those experiencing only IPV (AOR 1.49; 95% CI 0.84-2.38). No interaction between IPV and FV was detected for women married at or above majority. Laws that prohibit child marriage should be strengthened and health sector screening for violence experience could help identify women at risk of unmet need and improve women's reproductive agency.

Following the proposed worldwide switch from trivalent oral poliovirus vaccine (tOPV) to bivalent types 1 and 3 OPV (bOPV) in 2016, inactivated poliovirus vaccine (IPV) will be the only source of protection against poliovirus type 2. With most countries opting for one dose of IPV in routine immunisation schedules during this transition because of cost and manufacturing constraints, optimisation of protection against all poliovirus types will be a priority of the global eradication programme. We assessed the immunogenicity and safety of a novel monovalent high-dose inactivated poliovirus type 2 vaccine (mIPV2HD) in infants. This observer-blind, comparative, randomised controlled trial was done in a single centre in Panama. We enrolled healthy infants who had not received any previous vaccination against poliovirus. Infants were randomly assigned (1:1) by computer-generated randomisation sequence to receive a single dose of either mIPV2HD or standard trivalent IPV given concurrently with a third dose of bOPV at 14 weeks of age. At 18 weeks, all infants were challenged with one dose of monovalent type 2 OPV (mOPV2). Primary endpoints were seroconversion and median antibody titres to type 2 poliovirus 4 weeks after vaccination with mIPV2HD or IPV; and safety (as determined by the proportion and nature of serious adverse events and important medical events for 8 weeks after vaccination). The primary immunogenicity analyses included all participants for whom a post-vaccination blood sample was available. All randomised participants were included in the safety analyses. This trial is registered with ClinicalTrials.gov, number NCT02111135. Between April 14 and May 9, 2014, 233 children were enrolled and randomly assigned to receive mIPV2HD (117 infants) or IPV (116 infants). 4 weeks after vaccination with mIPV2HD or IPV, seroconversion to poliovirus type 2 was recorded in 107 (93·0%, 95% CI 86·8-96·9) of 115 infants in the mIPV2HD group compared with 86 (74·8%, 65·8-82·4) of 115 infants in the IPV group (difference between groups 18·3%, 95% CI 5·0-31·1; p<0·0001), and median antibody titres against poliovirus type 2 were 181 (95% CI 72·0-362·0) in the mIPV2HD group and 36 (18·0-113·8) in the IPV group (difference between groups 98·8, 95% CI 60·7-136·9; p<0·0001). Serious adverse events were reported for six (5%) of 117 infants in the mIPV2HD group and seven (6%) of 116 infants in the IPV group during the 8-week period after vaccination; none were related to vaccination. No important medical events were reported. Our findings lend support to the use of mIPV2HD as an option for stockpiling for outbreak response or primary protection in selected areas at risk for emergence of poliovirus type 2 during the next phase of the polio eradication plan.

Social networking sites have become increasingly popular venues for meeting sex partners. Today, some sexually transmitted disease (STD) programs conduct Internet-based partner services (IPS). The purpose of the study was to explore how the Internet is being used by STD prevention programs to perform partner services. We assessed US STD prevention programs receiving funds through the 2008-2013 Comprehensive STD Prevention Systems cooperative agreement. We (1) reviewed 2009 IPS protocols in 57 funding applications against a benchmark of national guidelines and (2) surveyed persons who conducted IPS in jurisdictions conducting IPS in 2012. Of the 57 project areas receiving Comprehensive STD Prevention Systems funds, 74% provided an IPS protocol. States with IPS protocols had larger populations and more gonorrhea and syphilis cases (t = 2.2-2.6; all Ps < .05), although not higher rates of infection. Most protocols included staffing (92%) and IPS documentation (87%) requirements, but fewer had evaluation plans (29%) or social networking site engagement strategies (16%). Authority to perform a complete range of IPS activities (send e-mail, use social networking sites) was associated with contacting more partners via IPSs (P < .05). This study provides a snapshot of IPS activities in STD programs in the United States. Further research is needed to move from assessment to generating data that can assist training efforts and program action and, finally, to enable efficient IPS programs that are integrated into STD prevention and control efforts.

Abused women often report a wide range of physical and psychological symptoms that present challenges to providers. Specifically, injuries to the head or strangulation, may initiate neurological changes that contribute to central nervous system (CNS) symptoms. These symptoms are often attributed to mental health diagnoses in this population. The purpose of this analysis is to examine the prevalence of and associations between reported probable traumatic brain injury (TBI) and CNS symptoms in a sample of women of African descent. A convenience sample of 901 women of African descent from Baltimore, MD and the US Virgin Islands, aged 18-55, was used to examine relationships among self-reported intimate partner violence (IPV), TBI, and CNS symptoms. Data were collected via Audio Computer-Assisted Self-Interview. Abused women who experienced a probable TBI were more likely to report CNS symptoms than those who did not. When controlling for demographics, IPV, and mental health symptoms, probable TBI was associated with a two point increase in CNS symptom frequency score (95% confidence interval: 1.55-2.93, p < 0.001). Women who reported both probable TBI and IPV were more likely than their abused counterparts who reported no TBI to report CNS symptoms. This relationship held true even when controlling for symptoms of depression and post-traumatic stress disorder (PTSD). Clinicians working with women should be aware of TBI as a possible etiology for symptoms in abused women. Appropriate screening and treatment protocols should be designed and implemented across medical settings to improve outcomes for women who have experienced IPV and TBI.

Even though we have already covered 99% of the path to eradicate poliomyelitis from the world, this disease is still causing paralysis in children. Its eradication means not only the end of wild poliovirus circulation, but vaccine-derived poliovirus circulation as well. Taking into account different factors such as: current epidemiological data, adverse events of the attenuated oral poliomyelitis vaccine (OPV), the availability of an injectable inactivated vaccine (IPV) without the potential of causing the severe adverse events of the oral vaccine (OPV), the efficacy and effectiveness of the IPV in several countries of the world where it has been used for several years, the rationale of changing the vaccination schedule in different Latin American countries; the Latin American Society of Pediatric Infectious Diseases (SLIPE) announces its recommendation of switching to IPV in Latin America, by this Declaration, with an Action Plan for 2014-2015 period as regards vaccination against polio policies in Latin America. 1. The optimal proposed schedule consists of four IPV doses (three doses in the primary schedule plus a booster dose), whether IPV is combined or not with other indicated vaccines in the immunization program of the country. During the OPV to IPV transition phase, an alternative schedule is acceptable; 2. Countries should set optimal strategies in order to maintain and improve vaccination coverage, and implement a nominal immunization registry; 3. Improving the Epidemiological Surveillance of Acute Flaccid Paralysis (AFP) and setting up an environmental surveillance program; 4. Setting up strategies for introducing IPV in National Immunization Programs, such as communicating properly with the population, among others; 5. Bringing scientific societies closer to decision makers; 6. Ensuring optimal supply and prices for IPV introduction; 7. Training vaccination teams; 8. Enhancing the distribution and storing logistics of vaccines. In addition to the scientific evidence, the countries that have not yet decided to switch to IPV should consider the implications of equity and social justice.

To describe the occurrence, dynamics and predictors of intimate partner violence (IPV) during pregnancy, including links with HIV, in urban Zimbabwe. A cross-sectional survey of 2042 post-natal women aged 15-49 years was conducted in six public primary healthcare clinics in low-income urban Zimbabwe. An adapted WHO questionnaire was used to measure IPV. Multivariate logistic regression was used to assess factors associated with IPV and severe (six or more episodes) IPV during pregnancy. 63.1% of respondents reported physical, emotional and/or sexual IPV during pregnancy: 46.2% reported physical and/or sexual violence, 38.9% sexual violence, 15.9% physical violence and 10% reported severe violence during pregnancy. Physical violence was less common during pregnancy than during the last 12 months before pregnancy (15.9% [95% CI 14.3-17.5] vs. 21.3% [95% confidence interval 19.5-23.1]). Reported rates of emotional (40.3% [95% CI 38.1-42.3] vs. 44.0% [95% CI 41.8-46.1]) and sexual violence (35.6% [95% CI 33.5-37.7] vs. 38.9% [95% CI 36.8-41.0]) were high during and before pregnancy. Associated factors were having a younger male partner, gender inequities, past abuse, problem drinking, partner control of woman's reproductive health and risky sexual practices. HIV status was not associated with either IPV or severe IPV, but reporting a partner with a known HIV status was associated with a lower likelihood of severe abuse. The rates of IPV during pregnancy in Zimbabwe are among the highest ever reported globally. Primary prevention of violence during childhood through adolescence is urgently needed. Antenatal care may provide an opportunity for secondary prevention but this requires further work. The relationship between IPV and HIV is complex in contexts where both are endemic. © 2013 John Wiley & Sons Ltd.

Young children are at significant risk of exposure to intimate partner violence (IPV), and vulnerable to exposure-related psychopathology, yet few studies investigate the effects of exposure to IPV on children under the age of 5 years. The current study investigated the role of maternal PTSD symptoms and parenting strategies in the relationship between mothers' IPV experiences and psychopathology in their young children, ages 3-6 years in a community-based cohort of 308 mother-child dyads at high risk for family violence. Data were collected from 2011 to 2014. IPV history and maternal PTSD symptoms were assessed by self-report questionnaires. Children's symptoms were assessed with a developmentally-sensitive psychiatric interview administered to mothers. Punitive/restrictive parenting was independently-coded from in-depth interviews with mothers about their disciplinary practices. Hypothesized direct and indirect pathways between physical and psychological IPV, maternal PTSD, maternal parenting style, and children's internalizing and externalizing symptoms were examined with mediation models. Results indicated that neither physical nor psychological IPV experienced by mothers was directly associated with children's symptoms. However, both types of victimization were associated with maternal PTSD symptoms. Examination of indirect pathways suggested that maternal PTSD symptoms mediated the relationship between mothers' psychological and physical IPV experiences and children's internalizing and externalizing symptoms and mothers' restrictive/punitive parenting mediated the relationship between mothers' psychological IPV and children's externalizing symptoms. In addition, there was a path from maternal physical IPV to child externalizing symptoms through both maternal PTSD symptoms and restrictive/punitive parenting. Findings highlight the importance of supporting parents in recovering from the sequelae of their own traumatic experiences, as their ensuing mental health symptoms and parenting behaviors may have a significant impact on their children's emotional health.

In 2008, a diphtheria, tetanus, acellular pertussis, and inactivated poliovirus combined vaccine (DTaP-IPV) was licensed for use in children 4 through 6 years of age. While pre-licensure studies did not demonstrate significant safety concerns, the number vaccinated in these studies was not sufficient to examine the risk of uncommon but serious adverse events. To assess the risk of serious adverse events following DTaP-IPV vaccination. The study was conducted from January 2009 through September 2012 in the Vaccine Safety Datalink (VSD) project. In the VSD, electronic vaccination and encounter data are updated and aggregated weekly as part of ongoing surveillance activities. Based on previous reports and biologic plausibility, eight potential adverse events were monitored: meningitis/encephalitis; seizures; stroke; Guillain-Barré syndrome; Stevens-Johnson syndrome; anaphylaxis; serious allergic reactions other than anaphylaxis; and serious local reactions. Adverse event rates in DTaP-IPV recipients were compared to historical incidence rates in the VSD population prior to 2009. Sequential probability ratio testing was used to analyze the data on a weekly basis. During the study period, 201,116 children received DTaP-IPV vaccine. Ninety-seven percent of DTaP-IPV recipients also received other vaccines on the same day, typically measles-mumps-rubella and varicella vaccines. There was no statistically significant increased risk of any of the eight pre-specified adverse events among DTaP-IPV recipients when compared to historical incidence rates. In this safety surveillance study of more than 200,000 DTaP-IPV vaccine recipients, there was no evidence of increased risk for any of the pre-specified adverse events monitored. Continued surveillance of DTaP-IPV vaccine safety may be warranted to monitor for rare adverse events, such as Guillain-Barré syndrome. Copyright © 2014 Elsevier Ltd. All rights reserved.

Intimate partner violence (IPV) is exceedingly common in conflict and post-conflict settings. We first seek to describe factors associated with past 12 month IPV amongst currently married women in Afghanistan, focused on the factors typically assumed to drive IPV. Second, to describe whether IPV is independently associated with a range of health outcomes. Cross-sectional analysis of currently married Afghan women, comprising the baseline study of a trial to prevent IPV. We use multinomial regression, reporting adjusted relative-risk ratios to model factors associated with the different forms of IPV, comparing no IPV, emotional IPV only, and physical IPV and emotional IPV. Second we assessed whether experience of emotional IPV, and physical IPV, were independently associated with health outcomes, reporting adjusted ß coefficients and adjusted odds ratios as appropriate. Nine hundred thirty five currently married women were recruited, 11.8% experienced only emotional IPV and 23.1% experienced physical and emotional IPV. Emotional IPV only was associated with attending a women's group, greater food insecurity, her husband having more than one wife, experiencing other forms of family violence, and more inequitable community gender norms. Experiencing both physical IPV and emotional IPV was associated with attending a women's group, more childhood trauma, husband cruelty, her husband having more than one wife, experiencing other forms of family violence, more inequitable community gender norms, and greater reported disability. Emotional IPV and physical IPV were independently associated with worse health outcomes. IPV remains common in Afghanistan. Economic interventions for women alone are unlikely to prevent IPV and potentially may increase IPV. Economic interventions need to also work with husbands and families, and work to transform community level gender norms. NCT03236948 . Registered 28 July 2017, retrospectively registered.

Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18–21 June 2012, pp. 588–592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

Recently, researchers are focusing on a new use of the Internet called the Internet of Things (IoT), in which enabled electronic devices can be remotely accessed over the Internet. As the realization of IoT concept is still in its early stages, manufacturers of Internet-connected devices and IoT web service providers are defining their proprietary protocols based on their targeted applications. Consequently, IoT becomes heterogeneous in terms of hardware capabilities and communication protocols. Addressing these heterogeneities by following open standards is a necessary step to communicate with various IoT devices. In this research, we assess the feasibility of applying existing open standards on resource-constrained IoT devices. The standard protocols developed in this research are OGC PUCK over Bluetooth, TinySOS, SOS over CoAP, and OGC SensorThings API. We believe that by hosting open standard protocols on IoT devices, not only do the devices become self-describable, self-contained, and interoperable, but innovative applications can also be easily developed with standardized interfaces. In addition, we use memory consumption, request message size, response message size, and response latency to benchmark the efficiency of the implemented protocols. In all, this research presents and evaluates standard-based solutions to better understand the feasibility of applying existing standards to the IoT vision.

Intimate partner violence (IPV) is a neglected public health issue in Iran. This study was conducted among married women residing in urban Rasht (northern Iran), to estimate the prevalence and frequency of different forms of IPV from husband and their associations with socio-demographic factors. We carried out a population-based cross-sectional survey with cluster sampling design from February to October 2015. The samples consisted of married women aged ≥ 18 years with total household in Rasht city (north Iran) as the sample frame. We administered the Revised Conflict Tactics Scale (CTS-2) to estimate prevalence of past-year IPV. Of 2091 women, 57.1% had suffered psychological aggression, 27.6% physical abuse, 26.6% sexual abuse, and 6.9% injury. A significant association with IPV was found for women with, age ≤ 40 years, unemployed, low education, husband's addiction and rented-householders. Women who experienced physical abuse, had less age at marriage than women without violence. Also women with sexual coercion had less length of marriage than other non-abused women. On logistic regression, the strongest predictor of psychological, physical and sexual abuse was unemployment of spouse, whereas for injury it was low educational level (<12 years) of women. Our findings suggest that risk of IPV is high in our population. There is an obvious need of preventive and treatment activities. Our findings point at that various forms of abuse are different from each other in terms of differing characteristics of the perpetrators and it might be that also different strategies are needed to reduce and prevent these violence. Confirmation by further research is needed.

Background Intimate partner violence (IPV) is the most common form of violence against women worldwide. IPV during pregnancy is an important risk factor for adverse health outcomes for women and their offspring. However, the prevalence of IPV during pregnancy is not well understood in China. The objective of this study was to estimate the pooled prevalence of IPV during pregnancy in China using a systematic review and meta-analysis. Methods Systematic literature searches were conducted in PubMed, Web of Science, CNKI, Wanfang, Weipu and CBM databases to identify relevant articles published from the inception of each database to January 31, 2016 that reported data on the prevalence of IPV during pregnancy in China. The Risk of Bias Tool for prevalence studies was used to assess the risk of bias in individual studies. Owing to significant between-study heterogeneity, a random-effects model was used to calculate the pooled prevalence and corresponding 95% confidence interval, and then univariate meta-regression analyses were performed to investigate the sources of heterogeneity. Subgroup analysis was conducted to explore the risk factors associated with IPV during pregnancy. Results Thirteen studies with a total of 30,665 individuals were included in this study. The overall pooled prevalence of IPV during pregnancy was 7.7% (95% CI: 5.6–10.1%) with significant heterogeneity (I2 = 97.8%, p < 0.001). The results of the univariate meta-regression analyses showed that only the variable “sample source” explained part of the heterogeneity in this study (p < 0.05). The characteristics “number of children” and “unplanned pregnancy” were determined as risk factors for experiencing violence during pregnancy. Conclusions The prevalence of IPV during pregnancy in China is considerable and one of the highest reported in Asia, which suggests that issues of violence against women during pregnancy should be included in efforts to improve the health of pregnant women and their offspring. In addition, a nationwide epidemiological study is needed to confirm the prevalence estimates and identify more risk factors for IPV during pregnancy. PMID:28968397

Oral polio vaccine (OPV) and Inactivated Polio Vaccine (IPV) have distinct advantages and limitations. IPV does not provide mucosal immunity and introduction of IPV to mitigate consequences of circulating vaccine-derived polio virus from OPV has very limited effect on transmission and OPV campaigns are essential for interrupting wild polio virus transmission, even in developed countries with a high coverage of IPV and protected sewer systems. The problem is magnified in many countries with limited resources. Requirement of refrigeration for storage and transportation for both IPV and OPV is also a major challenge in developing countries. Therefore, we present here long-term studies on comparison of a plant-based booster vaccine, which is free of virus and cold chain with IPV boosters and provide data on mucosal and systemic immunity and protection conferred by neutralizing antibodies. Mice were primed subcutaneously with IPV and boosted orally with lyophilized plant cells containing 1μg or 25μg polio viral protein 1 (VP1), once a month for three months or a single booster one year after the first prime. Our results show that VP1-IgG1 titers in single or double dose IPV dropped to background levels after one year of immunization. This decrease correlated with >50% reduction in seropositivity in double dose and <10% seropositivity in single dose IPV against serotype 1. Single dose IPV offered no or minimal protection against serotype 1 and 2 but conferred protection against serotype 3. VP1-IgA titers were negligible in IPV single or double dose vaccinated mice. VP1 antigen with two plant-derived adjuvants induced significantly high level and long lasting VP1-IgG1, IgA and neutralizing antibody titers (average 4.3-6.8 log2 titers). Plant boosters with VP1 and plant derived adjuvants maintained the same level titers from 29 to 400days and conferred the same level of protection against all three serotypes throughout the duration of this study. Even during period, when no plant booster was given (∼260days), VP1-IgG1 titers were maintained at high levels. Lyophilized plant cells expressing VP1 can be stored without losing efficacy, eliminating cold chain. Virus-free, cold-chain free vaccine is ready for further clinical development.

Intimate Partner Violence is Associated with Voluntary Sterilization in Women.
McCloskey, Laura Ann; Doran, Kelly A; Gerber, Megan R

Intimate partner violence (IPV) may interfere with women's use of preferred forms of contraception, resulting in unwanted pregnancies forcing women to seek permanent sterilization. A history of child sexual abuse (CSA) presages the risk for IPV in adulthood setting the stage for adverse reproductive outcomes. To determine whether CSA and IPV are associated with women's voluntary sterilization when adjusting for demographics and reproductive health history. This cross-sectional study is based on in-person interviews of women (N = 278) drawn from outpatients surveyed in more than 10 different clinics (N = 2465). Women's history of gender-based violence and bilateral tubal ligation (BTL) were assessed. About half of the women had a past history of IPV and 29% disclosed CSA. CSA predicted later entry into an abusive relationship (odds ratio [OR] = 6.7). Sterilization was reported by 19.6%. Parity (3+ children), having had an abortion, and receipt of welfare were associated with sterilization in univariate tests. Among those women receiving a BTL, 74% had violent partners. Adjusted multivariate logistic regressions, adjusted for demographics and reproductive history, indicated that having had an abusive partner increased the odds of sterilization; parity was also highly associated. CSA exerted only an indirect influence on sterilization via entry into violent relationships. IPV raises the likelihood that women will choose sterilization. Despite the importance of women's access to permanent contraception, priority should be given to screening for gender-based violence and promoting interventions.

The application of Information Technologies into Precision Agriculture methods has clear benefits. Precision Agriculture optimises production efficiency, increases quality, minimises environmental impact and reduces the use of resources (energy, water); however, there are different barriers that have delayed its wide development. Some of these main barriers are expensive equipment, the difficulty to operate and maintain and the standard for sensor networks are still under development. Nowadays, new technological development in embedded devices (hardware and communication protocols), the evolution of Internet technologies (Internet of Things) and ubiquitous computing (Ubiquitous Sensor Networks) allow developing less expensive systems, easier to control, install and maintain, using standard protocols with low-power consumption. This work develops and test a low-cost sensor/actuator network platform, based in Internet of Things, integrating machine-to-machine and human-machine-interface protocols. Edge computing uses this multi-protocol approach to develop control processes on Precision Agriculture scenarios. A greenhouse with hydroponic crop production was developed and tested using Ubiquitous Sensor Network monitoring and edge control on Internet of Things paradigm. The experimental results showed that the Internet technologies and Smart Object Communication Patterns can be combined to encourage development of Precision Agriculture. They demonstrated added benefits (cost, energy, smart developing, acceptance by agricultural specialists) when a project is launched.

We present a security protocol for the exchange of medical data via the Internet, based on the type/domain model. We discuss two applications of the protocol: in a system for the exchange of data for quality assurance, and in an on-line database of adverse reactions to drug use. We state that a type/domain security protocol can successfully comply with the complex requirements for data privacy and accessibility typical of such applications.

The immunogenicity and safety of one dose of Tdap-IPV (tetanus, diphtheria, acellular pertussis and inactivated poliomyelitis vaccine) and two doses of Td-IPV (tetanus, diphtheria and inactivated poliomyelitis vaccine) were assessed in adults who had not received a diphtheria- and tetanus-containing vaccine in the last 20 years. This open-label, multicentre study was conducted in adults aged ≥ 40 years with no diphtheria- and tetanus-containing vaccine in the last 20 years. Participants received one dose of Tdap-IPV followed by two doses of Td-IPV (0, 1, 6 month schedule). Primary immunogenicity objectives: to demonstrate acceptable seroprotection rates (percentage of participants with antibody titre above threshold) post-dose 3 for diphtheria (≥ 0.1IU/mL by seroneutralization assay [SNA]); tetanus (≥ 0.1IU/mL by enzyme-linked immunosorbent assay [ELISA]); and poliomyelitis (≥ 8 1/dil by SNA); and to evaluate the percentage of participants with an antibody concentration ≥ 5EU/mL (by ELISA) for pertussis antigens post-dose 1. Seroprotection rates were acceptable if the lower limit of the 95% confidence interval (CI) was >95%. Percentage of participants with basic clinical immunity against diphtheria (≥ 0.01IU/mL) was also assessed. Safety (adverse events [AEs] and serious AEs) was assessed after each dose. Overall, 336 participants were included (mean age: 60.2 years). Post-dose 3 seroprotection rates were: diphtheria, 94.6% (CI 91.5-96.8); tetanus and poliomyelitis, 100% (CI: 98.8-100). Percentage of participants with an antibody titre ≥ 5EU/mL against pertussis antigens was ≥ 95.8% for all five pertussis components. Basic clinical immunity against diphtheria was achieved in 100% (CI: 98.8-100) of participants. AEs were reported more frequently following vaccination with Tdap-IPV (post-dose 1: 65.3%) than with Td-IPV (post-dose 2: 48.3%; post-dose 3: 50.3%). This study highlights the benefits of using Tdap-IPV followed by two doses of Td-IPV in an adult population to achieve maximal protection against diphtheria, tetanus, poliomyelitis and pertussis simultaneously.

Worldwide, almost one third (30%) of women who have been in a relationship have experienced physical and/or sexual violence from an intimate partner. Given the considerable negative impacts of intimate partner violence (IPV) on women's physical health and well-being, there is an urgent need for rigorous evidence on violence prevention interventions. The study, comprising a cluster randomized controlled trial (RCT) and in-depth qualitative study, will assess the impact on women's past year experience of physical and/or sexual IPV of a participatory gender training curriculum (MAISHA curriculum) delivered to women participating in group-based microfinance in Tanzania. More broadly, the study aims to learn more about the factors that contribute to women's vulnerability to violence and understand how the intervention impacts on the lives of women and their families. Sixty-six eligible microfinance loan groups are enrolled and randomly allocated to: the 10-session MAISHA curriculum, delivered over 20 weeks (n = 33); or, to no intervention (n = 33). Study participants are interviewed at baseline and at 24 months post-intervention about their: household; partner; income; health; attitudes and social norms; relationship (including experiences of different forms of violence); childhood; and community. For the qualitative study and process evaluation, focus group discussions are being conducted with study participants and MAISHA curriculum facilitators. In-depth interviews are being conducted with a purposive sample of 18 participants. The primary outcome, assessed at 24 months post-intervention, is a composite of women's reported experience of physical and/or sexual IPV during the past 12 months. Secondary outcomes include: reported experience of physical, sexual and emotional/psychological IPV during the past 12 months, attitudes towards IPV and reported disclosure of IPV to others. The study forms part of a wider programme of research (MAISHA) that includes: a complementary cluster RCT evaluating the impact of delivering the MAISHA curriculum to women not receiving formal group-based microfinance; an economic evaluation; and a cross-sectional survey of men to explore male risk factors associated with IPV. MAISHA will generate rigorous evidence on violence prevention interventions, as well as further insights into the different forms and consequences of violence and drivers of violence perpetration.

Pulmonary infections can be life threatening for children with neuromuscular diseases who have impaired ability to clear secretions. Intrapulmonary percussive ventilation (IPV) is a pneumatic device that delivers air and aerosol to the lungs at frequencies of 200 to 300 cycles per minute at peak pressures from 20 to 40 cm H(2)O. Anecdotal reports and pilot studies show its safety and effectiveness in mobilizing secretions in patients with cystic fibrosis. To test the hypothesis that IPV used in a pulmonary program for adolescents with neuromuscular disease would reduce the number of days of antibiotic use for pulmonary infection. A randomized, controlled study was conducted to compare efficacy of IPV with incentive spirometry (IS) in reducing number of days of antibiotic use in adolescents with neuromuscular disease. The secondary endpoints were the number of respiratory infections, hospitalizations, and school days missed. A total of 18 patients were enrolled (9 IPV, 9 IS). Antibiotic use was significantly higher with IS (24/1000 patient-days) compared with IPV (0/1000 patient-days), (incidence rate ratio, 43; 95% confidence interval, 6-333). The IS group spent more days hospitalized (4.4/1000 patient-days vs 0/1000 patient-days) than the IPV group (incidence rate ratio, 8.5; 95% confidence interval, 1.1-67). The IPV group had 0 episodes of pneumonia or bacterial bronchitis compared with 3 events in the IS group, although this did not meet statistical significance. Intrapulmonary percussive ventilation as part of a preventive pulmonary regimen reduced days of antibiotic use and hospitalization for respiratory illness in adolescents with neuromuscular disease.

Intimate partner violence (IPV) victimization and perpetration and power imbalances in parenting partners may result in poor outcomes for parents and children. Previous work in this area has focused on the maternal experiences, neglecting to examine paternal effects. The present study aimed to elucidate the role of IPV, power, and equity in parenting and child outcomes in an urban sample of adolescent parents. 159 male and 182 female parents in a relationship were recruited through university-affiliated hospitals. Power, equity, and IPV were measured at 6 months post-partum and were used as predictors for parenting and child outcomes 12 months post-partum using general estimating equations. Gender interactions and mediation effects of depression were also assessed. Higher perceived relationship equity was related to better infant temperament (B = 0.052, SE = 0.023, p = 0.02) whereas higher partner power was related to poorer social development (B = -0.201, SE = 0.088, p = 0.02) and fine motor development (B = -0.195, SE = 0.078, p = 0.01). IPV victimization was associated with poor infant temperament (B = -2.925, SE = 1.083, p = 0.007) and lower parenting competence (B = -3.508, SE = 1.142, p = 0.002). Depression mediated the relationship between IPV and parenting and IPV and infant temperament. No gender effects were found. IPV, inequities, and power imbalances were disadvantageous for parenting and child outcomes. Our results suggest that these dynamics may negatively affect both males and females. Interventions to reduce violence in both partners and promote equity in relationships could benefit couples and their children.

This study assessed the antibody persistence, and the immunogenicity and safety of a booster dose of a DTaP-IPV//PRP∼T (Pentaxim®, Sanofi Pasteur's AcXim family) combined vaccine and of standalone vaccines one year after primary vaccination in the People's Republic of China. Participants (N=719) previously primed with DTaP-IPV//PRP∼T at 2, 3, 4 months (Group A, N=255), 3, 4, 5 months (Group B, N=233), or DTaP (Wuhan Institute of Biological Products), PRP-T (Act-Hib®) and IPV (Imovax® Polio) at 3, 4, 5 months (Group C, N=231) received boosters of the same vaccines at 18-20 months of age. Seroprotection (SP) and seroconversion (SC) were determined before and 1 month after the booster. Safety was monitored from parental reports. In all groups 87.6-100% of participants had pre-booster protective anti-PRP, -diphtheria, -tetanus and -poliovirus antibody titers; post-booster, all SP rates were 100% and SC was ≥ 80.4% for anti-pertussis titers ≥ 4-fold increase. Reactogenicity was low for each group. These data support the use of the DTaP-IPV//PRP∼T vaccine in the People's Republic of China compared to separate DTaP, IPV, and PRP∼T administration in terms of both safety and immunogenicity.

To determine the degree of interest in using a computer for the purpose of accessing services from a nurse practitioner (NP) at domestic violence shelters (DVSs); and to identify issues of privacy and confidentiality that might arise from participation by victims of intimate partner violence (IPV) in a Telehealth intervention. Focus groups with 19 women residing in two DVSs. Interviews were recorded, transcribed and themes were identified that answered the questions posed in the interviews. Most of the women understood the term NP and were favorably inclined to seek services from one. Over half of the women were not familiar with computer use, but were willing to learn in order to receive health care services, both for episodic needs and for maintenance of chronic conditions. After learning of the method proposed to allow them to access an NP through the internet while still protecting their privacy and confidentiality, the women felt comfortable with this approach to meeting their health care needs. Results from this study can be used to support the development and testing of Telehealth interventions for these victims of IPV.

Prevalence and correlates of intimate partner violence among older Chinese couples in Hong Kong.
Yan, Elsie; Chan, Ko Ling
2012-09-01
This study examined the prevalence and risk factors for intimate partner violence (IPV) among Chinese older couples in Hong Kong. A population representative sample was surveyed. The prevalence of IPV in older adults was found to be quite high in the present study, with a lifetime prevalence ranging from 1.4% to 53.6%, and a past year prevalence ranging from 0.4% to 36.1% for various forms of aggression. Results of logistic regression analyses showed that older persons who were younger among this "older" group, who were not employed, who had a substance abuse problem, who had witnessed parental violence during their childhood, who had a criminal history, who had a low level of assertiveness, who had an anger management problem, who experienced a low level of social support and/or experienced stressful conditions, were all more likely to fall victims of IPV. It is suggested that IPV in older couples is a complex phenomenon that is closely intertwined with other forms of domestic violence, including spousal violence, child abuse, in-law conflicts, and elderly adult abuse. Thus, before we have more definitive and concrete evidence that IPV in older couples should definitively come under the category of elder abuse or IPV, it is advisable to treat it under its own separate category of family violence.

To investigate the impact of intimate partner violence (IPV) on the risk of repeat induced abortion (RIA), we compared IPV history among women with and without previous induced abortion (IA). All consecutive women aged 18 years or more requiring IA in 12 Italian abortion clinics were eligible for inclusion in the study. They were asked to fill in an anonymous, self-developed questionnaire assessing sociodemographic data and their history of different types of violence and related risk factors. The analysis included 1030 women, 624 (60.6%) of whom reported a previous IA. Past or current IPV was reported by 19.3%: 7.0% reported sexual violence, 11.3% physical abuse and 12.1% psychological abuse. Past or current IPV was reported by 22.3% of women with RIA and 14.8% of those undergoing their first IA (adjusted odds ratio 1.57, 95% confidence interval 1.07-2.30; p = 0.02). When we considered sexual, psychological and physical abuse separately, we found that any kind of abuse was more frequent in women with RIA than in women with no previous IA. This study underlines the impact of IPV on the risk of RIA and suggests the need for screening for IPV among women requiring abortion, in order to identify women at risk of RIA and to improve their general and reproductive health.

Tacrolimus (TAC) is the cornerstone of immunosuppressive regimen in liver transplantation (LT). Its pharmacokinetics is characterized by a high interpatient and intrapatient variability (IPV) leading to an unpredictable dose-response relationship. The aim of our study was to evaluate the impact of TAC IPV (IPV) on graft and patient outcomes after LT. We retrospectively analyzed 812 LT recipients treated with TAC. The IPV of TAC concentrations was estimated by calculating the coefficient of variation (CV) of whole blood trough concentrations. Patients were categorized in 2 groups: low IPV (CV < 40%) and high IPV (CV ≥ 40%). There were significantly more neurologic complications (31.2% vs 16.6%, P < 0.001), cardiovascular complications (19.7% vs 9.7%, P < 0.001), and acute renal failure requiring dialysis (8.5% vs 2.2%, P < 0.001) in the high CV group than in the low CV group. Moreover, graft survival was significantly poorer in the high CV group (hazard ratio, 1.42; 95% confidence interval, 1.04-1.95; P = 0.03). A pretransplantation elevated Model for End-Stage Liver Disease score (P < 0.001) and Child-Pugh grade (P < 0.001) were identified as risk factors for presenting a high CV. A high CV of TAC concentrations was found to be predictive of TAC-related toxicity and poorer survival.

Inactivated poliovirus vaccine (IPV) is rarely used in tropical developing countries. To generate additional scientific information, especially on the possible emergence of vaccine-derived polioviruses (VDPVs) in an IPV-only environment, we initiated an IPV introduction project in Yogyakarta, an Indonesian province. In this report, we present the coverage, immunity, and VDPV surveillance results. In Yogyakarta, we established environmental surveillance starting in 2004; and conducted routine immunization coverage and seroprevalence surveys before and after a September 2007 switch from oral poliovirus vaccine (OPV) to IPV, using standard coverage and serosurvey methods. Rates and types of polioviruses found in sewage samples were analyzed, and all poliovirus isolates after the switch were sequenced. Vaccination coverage (>95%) and immunity (approximately 100%) did not change substantially before and after the IPV switch. No VDPVs were detected. Before the switch, 58% of environmental samples contained Sabin poliovirus; starting 6 weeks after the switch, Sabin polioviruses were rarely isolated, and if they were, genetic sequencing suggested recent introductions. This project demonstrated that under almost ideal conditions (good hygiene, maintenance of universally high IPV coverage, and corresponding high immunity against polioviruses), no emergence and circulation of VDPV could be detected in a tropical developing country setting. © The Author 2014.

Selecting a communications and network architecture for future manned space flight requires an evaluation of the varying goals and objectives of the program, development of communications and network architecture evaluation criteria, and assessment of critical architecture trades. This paper uses Cx Program proposed exploration activities as a guideline; lunar sortie, outpost, Mars, and flexible path options are described. A set of proposed communications network architecture criteria are proposed and described. They include: interoperability, security, reliability, and ease of automating topology changes. Finally a key set of architecture options are traded including (1) multiplexing data at a common network layer vs. at the data link layer, (2) implementing multiple network layers vs. a single network layer, and (3) the use of a particular network layer protocol, primarily IPv6 vs. Delay Tolerant Networking (DTN). In summary, the protocol options are evaluated against the proposed exploration activities and their relative performance with respect to the criteria are assessed. An architectural approach which includes (a) the capability of multiplexing at both the network layer and the data link layer and (b) a single network layer for operations at each program phase, as these solutions are best suited to respond to the widest array of program needs and meet each of the evaluation criteria.
The Interplanetary Internet: A Communications Infrastructure for Mars Exploration

A successful program of Mars Exploration will depend heavily on a robust and dependable space communications infrastructure that is well integrated with the terrestrial Internet. In the same way that the underpinnings of the Internet are the standardized "TCP/IP" suite of protocols, an "Interplanetary Internet" will need a similar set of capabilities that can support reliable communications across vast distances and highly stressed communications environments. For the past twenty years, the Consultative Committee for Space Data Systems (CCSDS) has been developing standardized long- haul space link communications techniques that are now in use by over two hundred missions within the international space community. New CCSDS developments, shortly to be infused into Mars missions, include a proximity link standard and a store-and- forward file transfer protocol. As part of its `Next Generation Internet' initiative, the U.S. Defense Advanced Projects Agency (DARPA) recently supported an architectural study of a future "InterPlaNetary Internet" (IPN). The IPN architecture assumes that in short-delay environments - such as on and around Mars - standard Internet technologies will be adapted to the locally harsh environment and deployed within surface vehicles and orbiting relays. A long-haul interplanetary backbone network that includes Deep Space Network (DSN) gateways into the terrestrial Internet will interconnect these distributed internets that are scattered across the Solar System. Just as TCP/IP unites the Earth's "network of networks" to become the Internet, a new suite of protocols known as "Bundling" will enable the IPN to become a "network of internets" to support true interplanetary dialog. An InterPlaNetary Internet Research Group has been established within the Internet community to coordinate this research and NASA has begun to support the further development of the IPN architecture and the Bundling protocols. A strategy is being developed whereby the current set of standard CCSDS data communications protocols can be incrementally evolved so that true InterPlaNetary Internet operations are feasible by the end of the decade. The strategy - which is already in progress via the deployment of Mars relay links - needs individual missions to each contribute increments of capability so that a standard communications infrastructure can rapidly accrete. This paper will describe the IPN architectural concepts, discuss the current set of standard data communications capabilities that exist to support Mars exploration and review the proposed new developments. We will also postulate that the concept is scalable and can grow to support future scenarios where human intelligence is widely distributed across the Solar System and day-to-day communications dialog among planets is routine. 1 2 3 4 5

Mobile IPv6 (MIPv6) is one of the pioneer standards that support mobility in IPv6 environment. It has been designed to support different types of technologies for providing seamless communications in next generation network. However, MIPv6 and subsequent standards have some limitations due to its handoff latency. In this paper, a fuzzy logic based mechanism is proposed to reduce the handoff latency of MIPv6 for Layer 2 (L2) by scanning the Access Points (APs) while the Mobile Node (MN) is moving among different APs. Handoff latency occurs when the MN switches from one AP to another in L2. Heterogeneous network is considered in this research in order to reduce the delays in L2. Received Signal Strength Indicator (RSSI) and velocity of the MN are considered as the input of fuzzy logic technique. This technique helps the MN to measure optimum signal quality from APs for the speedy mobile node based on fuzzy logic input rules and makes a list of interfaces. A suitable interface from the list of available interfaces can be selected like WiFi, WiMAX or GSM. Simulation results show 55% handoff latency reduction and 50% packet loss improvement in L2 compared to standard to MIPv6.

The poliovirus vaccine field is moving towards novel vaccination strategies. Withdrawal of the Oral Poliovirus Vaccine and implementation of the conventional Inactivated Poliovirus Vaccine (cIPV) is imminent. Moreover, replacement of the virulent poliovirus strains currently used for cIPV with attenuated strains is preferred. We generated Cold-Adapted Viral Attenuation (CAVA) poliovirus strains by serial passage at low temperature and subsequent genetic engineering, which contain the capsid sequences of cIPV strains combined with a set of mutations identified during cold-adaptation. These viruses displayed a highly temperature sensitive phenotype with no signs of productive infection at 37°C as visualized by electron microscopy. Furthermore, decreases in infectious titers, viral RNA, and protein levels were measured during infection at 37°C, suggesting a block in the viral replication cycle at RNA replication, protein translation, or earlier. However, at 30°C, they could be propagated to high titers (9.4–9.9 Log10TCID50/ml) on the PER.C6 cell culture platform. We identified 14 mutations in the IRES and non-structural regions, which in combination induced the temperature sensitive phenotype, also when transferred to the genomes of other wild-type and attenuated polioviruses. The temperature sensitivity translated to complete absence of neurovirulence in CD155 transgenic mice. Attenuation was also confirmed after extended in vitro passage at small scale using conditions (MOI, cell density, temperature) anticipated for vaccine production. The inability of CAVA strains to replicate at 37°C makes reversion to a neurovirulent phenotype in vivo highly unlikely, therefore, these strains can be considered safe for the manufacture of IPV. The CAVA strains were immunogenic in the Wistar rat potency model for cIPV, inducing high neutralizing antibody titers in a dose-dependent manner in response to D-antigen doses used for cIPV. In combination with the highly productive PER.C6 cell culture platform, the stably attenuated CAVA strains may serve as an attractive low-cost and (bio)safe option for the production of a novel next generation IPV.

In Nigeria, there is paucity of information on the IPV burden and experience among young women in courtship and dating relationships. This study assesses the prevalence and correlates of IPV in female undergraduate and postgraduate students in a tertiary institution. The study was a cross-sectional survey. A four-stage sampling technique was used to select 1,100 undergraduate and 255 postgraduate female students from the University of Ibadan, Nigeria. Data was collected using a 43-item self-administered structured questionnaire. Descriptive statistics and multivariate analyses were carried out at 0.05 level of significance. The life-time prevalence of IPV was 42.3% (postgraduate: 34.5%, undergraduate: 44.1%; P < 0.05). Lifetime experience of psychological, physical and sexual IPV were 41.8%, 7.9% and 6.6% respectively. Recent experience (within the previous 12 months) of violence was also more frequently reported by respondents who had a previous history of physical (62.5%) (OR = 2.65; 95% CI: 2.02-3.49) and sexual (53.2%) (OR = 1.63; 95% CI:1.12-2.35) violence than respondents who had no such history. Postgraduate (OR = 0.64; 95% CI: 0.46-0.87) and married (OR = 0.53; 95% CI: 0.35-0.78) students were less likely to have experienced IPV than undergraduate and single students respectively. Students who smoked (OR = 2.46; 95% CI: 1.58-3.83); consumed alcohol (OR = 2.36; 95% CI: 1.82- 3.06); and with history of interparental violence (OR = 2.40; 95% CI: 1.88- 3.07) had a higher likelihood of experiencing violence than students who were not exposed to these behaviors. Adverse effects (such as the inability to concentrate) of IPV on academic performance were reported by 10.3% of victims. The prevalence of IPV was high. There is the urgent need for interventions that will reduce vulnerability by addressing modifiable risk factors like smoking and alcohol consumption. Interventions should also encourage seeking health care following violence to reduce its consequences.
Oral and Inactivated Poliovirus Vaccines in the Newborn: A review

Background Oral poliovirus vaccine (OPV) remains the vaccine-of-choice for routine immunization and supplemental immunization activities (SIAs) to eradicate poliomyelitis globally. Recent data from India suggested lowerthanexpected immunogenicity of an OPV birth dose, prompting a review of the immunogenicity of OPV or inactivated poliovirus vaccine (IPV) when administered at birth. Methods We evaluated the seroconversion and reported adverse events among infants given a single birth dose (given ≤7 days of life) of OPV or IPV through a systematic review of published articles and conference abstracts from 1959-2011 in any language found on PubMed, Google Scholar, or reference lists of selected articles. Results 25 articles from 13 countries published between1959 and 2011 documented seroconversion rates in newborns following an OPV dose given within the first seven days of life. There were 10 studies that measured seroconversion rates between 4 and 8 weeks of a single birth dose of TOPV, using an umbilical cord blood draw at the time of birth to establish baseline antibody levels. The percentage of newborns who seroconverted at 8 weeks range 6-42% for poliovirus type 1, 2-63% for type 2, and 1-35% for type 3). For mOPV type 1, seroconversion ranged from 10-76%; mOPV type 3, the range was 12-58%; and for the one study reporting bOPV, it was 20% for type 1 and 7% for type 3. There were four studies of IPV in newborns with a seroconversion rate of 8-100% for serotype 1, 15-100% for serotype 2, and 15-94% for serotype 3, measured at 4-6 weeks of life. No serious adverse events related to newborn OPV or IPV dosing were reported, including no cases of acute flaccid paralysis. Conclusions There is great variability of the immunogenicity of a birth dose of OPV for reasons largely unknown. Our review confirms the utility of a birth dose of OPV, particularly in countries where early induction of polio immunity is imperative. IPV has higher seroconversion rates in newborns and may be a superior choice in countries which can afford IPV, but there have been studies of an IPV dose for newborns. PMID:22728224

Internet-delivered treatment has the potential to expand access to evidence-based cognitive-behavioral therapy (CBT) for pediatric headache, and has demonstrated efficacy in small trials for some youth with headache. We used a mixed methods approach to identify effective components of CBT for this population. In Study 1, component profile analysis identified common interventions delivered in published RCTs of effective CBT protocols for pediatric headache delivered face-to-face or via the Internet. We identified a core set of three treatment components that were common across face-to-face and Internet protocols: 1) headache education, 2) relaxation training, and 3) cognitive interventions. Biofeedback was identified as an additional core treatment component delivered in face-to-face protocols only. In Study 2, we conducted qualitative interviews to describe the perspectives of youth with headache and their parents on successful components of an Internet CBT intervention. Eleven themes emerged from the qualitative data analysis, which broadly focused on patient experiences using the treatment components and suggestions for new treatment components. In the Discussion, these mixed methods findings are integrated to inform the adaptation of an Internet CBT protocol for youth with headache. PMID:29503787

NASA's Glenn Research Center (GRC) defines and develops advanced technology for high priority national needs in communications technologies for application to aeronautics and space. GRC tasked Computer Networks and Software Inc. (CNS) to examine protocols and architectures for an In-Space Internet Node. CNS has developed a methodology for network reference models to support NASA's four mission areas: Earth Science, Space Science, Human Exploration and Development of Space (REDS), Aerospace Technology. This report applies the methodology to three space Internet-based communications scenarios for future missions. CNS has conceptualized, designed, and developed space Internet-based communications protocols and architectures for each of the independent scenarios. The scenarios are: Scenario 1: Unicast communications between a Low-Earth-Orbit (LEO) spacecraft inspace Internet node and a ground terminal Internet node via a Tracking and Data Rela Satellite (TDRS) transfer; Scenario 2: Unicast communications between a Low-Earth-Orbit (LEO) International Space Station and a ground terminal Internet node via a TDRS transfer; Scenario 3: Multicast Communications (or "Multicasting"), 1 Spacecraft to N Ground Receivers, N Ground Transmitters to 1 Ground Receiver via a Spacecraft.

The aim of the study was to explore the pathways by which childhood sexual abuse (CSA), psychological and physical intimate partner violence (IPV) during pregnancy, and other covariates relate to each other and to posttraumatic stress disorder (PTSD) symptoms in the postpartum period. The sample comprised 456 women who gave birth at a maternity service for high-risk pregnancies in Rio de Janeiro, Brazil, interviewed at 6-8 weeks after birth. A path analysis was carried out to explore the postulated pathways between exposures and outcome. Trauma History Questionnaire, Conflict Tactics Scales and Posttraumatic Stress Disorder Checklist were used to assess information about exposures of main interest and outcome. The link between CSA and PTSD symptoms was mediated by history of trauma, psychiatric history, psychological IPV, and fear of childbirth during pregnancy. Physical IPV was directly associated with postnatal PTSD symptoms, whereas psychological IPV connection seemed to be partially mediated by physical abuse and fear of childbirth during pregnancy. The role of CSA, IPV, and other psychosocial characteristics on the occurrence of PTSD symptoms following childbirth as well as the intricate network of these events should be acknowledged in clinic and intervention approaches.

Implementation and Evaluation of Four Interoperable Open Standards for the Internet of Things
Jazayeri, Mohammad Ali; Liang, Steve H. L.; Huang, Chih-Yuan
2015-01-01
Recently, researchers are focusing on a new use of the Internet called the Internet of Things (IoT), in which enabled electronic devices can be remotely accessed over the Internet. As the realization of IoT concept is still in its early stages, manufacturers of Internet-connected devices and IoT web service providers are defining their proprietary protocols based on their targeted applications. Consequently, IoT becomes heterogeneous in terms of hardware capabilities and communication protocols. Addressing these heterogeneities by following open standards is a necessary step to communicate with various IoT devices. In this research, we assess the feasibility of applying existing open standards on resource-constrained IoT devices. The standard protocols developed in this research are OGC PUCK over Bluetooth, TinySOS, SOS over CoAP, and OGC SensorThings API. We believe that by hosting open standard protocols on IoT devices, not only do the devices become self-describable, self-contained, and interoperable, but innovative applications can also be easily developed with standardized interfaces. In addition, we use memory consumption, request message size, response message size, and response latency to benchmark the efficiency of the implemented protocols. In all, this research presents and evaluates standard-based solutions to better understand the feasibility of applying existing standards to the IoT vision. PMID:26402683

We conducted longitudinal analyses examining the associations between intimate partner violence (IPV) attitudes and women’s reported IPV in couples (N = 762) using 3 waves of data from a randomized controlled trial in Maharashtra, India. We found that, between Waves 1 and 2, men’s and women’s acceptance of IPV in the overall population decreased significantly while reports of IPV increased. These changes, we hypothesize, are evidence of an exogenous shock, possibly a high profile rape in Delhi in December 2012, that may have impacted the entire population. Cross-sectional associations between men’s attitudes towards IPV and reported IPV were not significant in Wave 1, while positively and significantly associated in Waves 2 and 3. Longitudinal analysis showed that reduction in men’s acceptance of IPV between Waves 1 and 2 was associated with a lower likelihood of reported IPV in Wave 3. Women’s Wave 1 acceptance of IPV was positively associated with reported IPV in the Wave 1 cross-sectional analysis, while Wave 2 and Wave 3 measures of IPV acceptance were negatively associated with reported IPV in Waves 2 and 3 respectively. Longitudinal analyses of the change in women’s attitudes towards IPV from Wave 1 to 2 and reported IPV in Wave 3 were insignificant. However, When women first reported IPV in Waves 2 or 3 they were less likely to report acceptance of IPV in that same wave. Findings suggest that changes in husbands’ IPV acceptance is predictive of subsequent IPV, while newly experienced IPV predicts decreased IPV acceptance for women. Wave 2 and Wave 3 results were significant for the control group only, evidence that the intervention affected those associations, potentially changing attitudes more quickly than behavior. We recommend interventions that expose community opposition to IPV as a new social norm, and analysis of how the 2012 Delhi rape case may have affected these norms. PMID:28260640
Psychological Predictors of Sexual Intimate Partner Violence against Black and Hispanic Women
Preiser, Brianna
2017-01-01
Background: Although various types of intimate partner violence (IPV) tend to co-occur, risk factors of each type of IPV may differ. At the same time, most of the existing literature on risk factors of IPV among minorities has used a cross-sectional design and has focused on physical rather than sexual IPV. We conducted the current study to compare Black and Hispanic women for psychological predictors of change in sexual IPV over time. Methods: Using data from the Fragile Families and Child Wellbeing Study (FFCWS), this study followed 561 Black and 475 Hispanic women with their male partners for four years. Independent variables included male partners’ depression, anxiety, problem alcohol use, and male-to-female physical and psychological IPV perpetration. The dependent variable was sexual IPV reported by female partners, measured at baseline, two years, and four years later. Covariates included age, income, marital status and education level. We used a multi-group latent growth curve model (LGCM) to explain intercept, linear, and quadratic slopes, which represent the baseline, and linear and curvilinear trajectories of male-to-female sexual IPV, where groups were defined based on ethnicity. Results: Psychological IPV was associated with sexual IPV at baseline among both ethnic groups. The male partner’s depression was a risk factor for an increase in sexual IPV over time among Black but not Hispanic women. Anxiety, problem alcohol use and physical IPV did not have an effect on the baseline or change in sexual IPV over time. Psychological IPV was not associated with an increase in sexual IPV over time in either ethnic group. Conclusions: There is a need for screening of sexual IPV in the presence of psychological IPV among minority women. There is also a need for screening and treatment of male partners’ depression as a strategy to reduce sexual IPV among Black women.

Quadracel: Vaccination Against Diphtheria, Tetanus, Pertussis, and Poliomyelitis in Children.
Mosley, Juan F; Smith, Lillian L; Parke, Crystal K; Brown, Jamal A; LaFrance, Justin M; Clark, Patricia K
2016-04-01
Vaccinations in school-aged children are required by state and local law to maintain high vaccination coverage rates, as well as low rates of vaccine-preventable diseases. Diphtheria, tetanus, and pertussis are childhood diseases that can be life threatening; poliomyelitis, another childhood disease, can be disabling. In turn, vaccinations were developed to provide protection against these diseases. Today, several vaccinations are recommended for children, including but not limited to diphtheria, tetanus, and pertussis (DTaP) and poliomyelitis (IPV). DTaP requires five doses, and IPV requires four. Quadracel (diphtheria and tetanus toxoids and acellular pertussis adsorbed and inactivated poliovirus vaccine, Sanofi Pasteur Inc.) is a new vaccination developed to condense the last dose of both DTaP and IPV so they do not have to be given separately, thus reducing the total number of vaccinations required. The Quadracel vaccine is an option for use in children who are completing the DTaP and IPV series. In a randomized, controlled, phase 3, pivotal trial, Quadracel proved to be as efficacious and safe as Daptacel (diphtheria and tetanus toxoids and acellular pertussis vaccine adsorbed, Sanofi Pasteur Inc.) and IPOL (poliovirus vaccine inactivated, Sanofi Pasteur Inc.), given separately, to children between the ages of 4 and 6 years. Quadracel should be recommended to parents who have children between the ages of 4 and 6 years who meet the necessary administration criteria and need to finalize their DTaP and IPV series. Quadracel's administration in the vaccination series replaces one additional injection, which may benefit children who are afraid of receiving shots and parents who need to schedule one less doctor's appointment.

NASA is designing future complex satellite missions ranging from single satellites and constellations to space networks and sensor webs. These missions require more interoperability, autonomy, and coordination than previous missions; in addition, a desire exists to have scientists retrieve data directly from the satellite rather than a central distribution source. To meet these goals, NASA has been studying the possibility of extending the Transmission Control Protocol/Internet Protocol (TCP/IP) suite for spacebased applications.

The Operating Missions as Nodes on the Internet (OMNI) project has shown that Internet technology works in space missions through a demonstration using the UoSAT-12 spacecraft. An Internet Protocol (IP) stack was installed on the orbiting UoSAT-12 spacecraft and tests were run to demonstrate Internet connectivity and measure performance. This also forms the basis for demonstrating subsequent scenarios. This approach provides capabilities heretofore either too expensive or simply not feasible such as reconfiguration on orbit. The OMNI project recognized the need to reduce the risk perceived by mission managers and did this with a multi-phase strategy. In the initial phase, the concepts were implemented in a prototype system that includes space similar components communicating over the TDRS (space network) and the terrestrial Internet. The demonstration system includes a simulated spacecraft with sample instruments. Over 25 demonstrations have been given to mission and project managers, National Aeronautics and Space Administration (NASA), Department of Defense (DoD), contractor technologists and other decisions makers, This initial phase reached a high point with an OMNI demonstration given from a booth at the Johnson Space Center (JSC) Inspection Day 99 exhibition. The proof to mission managers is provided during this second phase with year 2000 accomplishments: testing the use of Internet technologies onboard an actual spacecraft. This was done with a series of tests performed using the UoSAT-12 spacecraft. This spacecraft was reconfigured on orbit at very low cost. The total period between concept and the first tests was only 6 months! On board software was modified to add an IP stack to support basic IP communications. Also added was support for ping, traceroute and network timing protocol (NTP) tests. These tests show that basic Internet functionality can be used onboard spacecraft. The performance of data was measured to show no degradation from current approaches. The cost to implement is much less than current approaches due to the availability of highly reliable and standard Internet tools. Use of standard Internet applications onboard reduces the risk of obsolescence inherent in custom protocols due to extremely wide use across all domains. These basic building blocks provide the framework for building onboard software to support direct user communication with payloads including payload control. Other benefits are payload to payload communication from dissimilar spacecraft, constellations of spacecraft, and reconfigurability on orbit. This work is funded through contract with the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC).

The objectives of this study were to identify the prevalence of past-year intimate partner violence (IPV) among women Veterans utilizing Veterans Health Administration (VHA) primary care, and to document associated demographic, military, and primary care characteristics. This was a retrospective cohort design, where participants completed a telephone survey in 2012 (84% participation rate); responses were linked to VHA administrative data for utilization in the year prior to the survey. A national stratified random sample of 6,287 women Veteran VHA primary care users participated in the study. Past-year IPV was assessed using the HARK screening tool. Self-report items and scales assessed demographic and military characteristics. Primary care characteristics were assessed via self-report and VHA administrative data. The prevalence of past-year IPV among women Veterans was 18.5% (se = 0.5%), with higher rates (22.2% - 25.5%) among women up to age 55. Other demographic correlates included indicators of economic hardship, lesbian or bisexual orientation, and being a parent/guardian of a child less than 18 years old. Military correlates included service during Vietnam to post-Vietnam eras, less than 10 years of service, and experiences of Military Sexual Trauma (MST). Most (77.3%, se = 1.2%) women who experienced IPV identified a VHA provider as their usual provider. Compared with women who did not report past-year IPV, women who reported IPV had more primary care visits, yet experienced lower continuity of care across providers. The high prevalence of past-year IPV among women beyond childbearing years, the majority of whom primarily rely on VHA as a source of health care, reinforces the importance of screening all women for IPV in VHA primary care settings. Key considerations for service implementation include sensitivity with respect to sexual orientation, race/ethnicity, and other aspects of diversity, as well as care coordination and linkages with social services and MST-related care.

Our objective was to examine the multilevel correlates of women's justification of wife beating in Bangladesh, a form of intimate partner violence (IPV). We focus on individual-level schooling, community-level media exposure among women and their interaction. A cross-sectional study using data from the 2011 Bangladesh Demographic and Health Survey. Our sample included 17 749 ever-married women 15-49 years in 600 communities. We fit 6 multilevel logistic regression models to examine factors associated with justifying IPV; focusing on a woman's completed grades of schooling; frequent (at least once weekly) community-level media exposure among women via newspaper/magazine, television and radio; and their cross-level interaction. At the individual level, completing more grades of schooling than the community average was negatively associated with justifying IPV (0.95, 95% CI 0.94 to 0.97). The main effects of women's community-level media exposure were not significant, but suggested that frequent exposure to newspaper/magazine or television was negatively associated with justifying IPV, while exposure to radio was positively associated. In cross-level interactions, a woman's completed grades of schooling above the community average was protective against justifying IPV, even in communities where women's exposure to radio would otherwise increase the odds of justifying IPV. Different forms of media likely send different messages about gender and IPV. Girls' schooling should remain a priority, given its protective effect against justifying wife beating. Targeting girls and women who do not receive any schooling for intervention may yield the most benefit in terms of normative change regarding IPV against women.

Indashyikirwa is a Rwandan program that seeks to prevent intimate partner violence (IPV) and support healthy, equitable relationships. A fundamental program aspect is a 5-month curriculum among heterosexual couples designed to identify the causes and consequences of economic, emotional, physical, and sexual IPV, and build skills to manage triggers of IPV. The program also trained opinion leaders to more effectively prevent and respond to IPV, and established women's safe spaces to educate women about their rights, refer or accompany women who wish to report abuse or seek services. Drawing on 30 interviews with couples and 9 interviews with opinion leaders before and after completing the Indashyikirwa trainings, this article highlights beneficiaries' perceived consequences of IPV, and how such perceptions were influenced through the Indashyikirwa program. Interviews were conducted in Kinyarwanda, recorded, translated, and transcribed into English and analyzed thematically. The data reveal a depth of understanding of consequences of various forms of IPV. Although several participants justified more minor forms of men's physical IPV, such as slapping, severe consequences of physical IPV were most readily identified and sanctioned. Various harms of emotional and economic IPV were reported, yet these forms of IPV were typically less socially sanctioned or identified as IPV. Conceptions of sexual IPV were influenced by inequitable gender norms, and not typically recognized as a violation under the law. Although the data do not yet demonstrate the long-term impact, collectively identifying the overlapping consequences and underlying power inequalities for all forms of IPV, the legal rights protecting against various forms of IPV, and the benefits of nonviolent, equitable relationships, appeared to be helpful to shift perceptions of consequences of IPV. Implications of the findings for the program and broader IPV prevention are identified.

Some gynaecological and pregnancy-associated conditions are more common in abused women than in non-abused women, but this has not been examined in family practice. We aimed to investigate intimate partner violence (IPV) prevalence in family practice and to investigate whether gynaecological and pregnancy-associated conditions are more common in abused women than in non-abused women. We conducted a cross-sectional waiting room survey in 12 family practices in the Netherlands in 2012. Women were eligible if they were of 18 years or older. Questionnaires measured IPV and gynaecological and pregnancy-associated conditions. Chi-square tests were used to assess the differences in gynaecological and pregnancy-associated conditions between abused women and non-abused women. The response rate was 86% (262 of 306 women). The past-year prevalence of IPV in women who had had an intimate relationship in the past year and were not accompanied by their partner was 8.7% (n = 195). Lifetime prevalence of women who had ever had an intimate relationship, but not in the past year, was 17.6% (n = 51). Sexually transmitted infections (STIs) [odds ratio (OR) = 4.6, 95% confidence interval [CI] = 1.7-12.5, n = 240], menstrual disorders (OR = 3.7, 95% CI = 1.2-11.2, n = 143), sexual problems (OR = 3.3, 95% CI = 1.2-9.3, n = 229), miscarriages (OR = 2.5, 95% CI = 1.062-5.8, n = 202) and induced abortions (OR = 2.7, 95% CI = 1.028-7.3, n = 202) were significantly more common in abused women than in non-abused women. Family physicians should ask about IPV when women present with STIs, menstrual disorders, sexual problems, miscarriages or induced abortions. To improve the recognition of IPV, future research needs to investigate whether a combination of symptoms offers improved prediction of IPV. © The Author 2016. Published by Oxford University Press.

Globally, adolescent women are at risk for gender-based violence (GBV) including sexual violence and intimate partner violence (IPV). Those in economically distressed settings are considered uniquely vulnerable. Female adolescents aged 15-19 from Baltimore, Maryland, USA; New Delhi, India; Ibadan, Nigeria; Johannesburg, South Africa; and Shanghai, China (n = 1,112) were recruited via respondent-driven sampling to participate in a cross-sectional survey. We describe the prevalence of past-year physical and sexual IPV, and lifetime and past-year non-partner sexual violence. Logistic regression models evaluated associations of GBV with substance use, sexual and reproductive health, mental health, and self-rated health. Among ever-partnered women, past-year IPV prevalence ranged from 10.2% in Shanghai to 36.6% in Johannesburg. Lifetime non-partner sexual violence ranged from 1.2% in Shanghai to 12.6% in Johannesburg. Where sufficient cases allowed additional analyses (Baltimore and Johannesburg), both IPV and non-partner sexual violence were associated with poor health across domains of substance use, sexual and reproductive health, mental health, and self-rated health; associations varied across study sites. Significant heterogeneity was observed in the prevalence of IPV and non-partner sexual violence among adolescent women in economically distressed urban settings, with upwards of 25% of ever-partnered women experiencing past-year IPV in Baltimore, Ibadan, and Johannesburg, and more than 10% of adolescent women in Baltimore and Johannesburg reporting non-partner sexual violence. Findings affirm the negative health influence of GBV even in disadvantaged urban settings that present a range of competing health threats. A multisectoral response is needed to prevent GBV against young women, mitigate its health impact, and hold perpetrators accountable. Copyright © 2014 Society for Adolescent Health and Medicine.

2006-12-01
A prospective study of U.S. Navy recruits (N = 5,498) examined whether premilitary intimate partner violence (IPV) was associated with attrition. Overall, more than one-fourth of recruits reported premilitary physical IPV and more than two-thirds reported premilitary verbal IPV. Women reported more perpetration and receipt of IPV than men, and married or cohabiting respondents reported more IPV than single respondents. Both perpetration and receipt of IPV significantly predicted attrition within 4 years. However, after controlling for other forms of IPV, only receipt of physical IPV significantly predicted attrition. In only one analysis did associations between IPV and attrition vary according to marital status or gender; premilitary receipt of verbal IPV had different effects on women and men.

Background and aims Contingency management (CM) is one of the most effective behavioral interventions to promote drug abstinence, but availability of this treatment is limited. We evaluated the efficacy and acceptability of Internet-based CM relative to an Internet-based monitoring and goal setting control group in a nationwide sample of cigarette smokers. Design Randomized controlled trial with 3- and 6-month follow ups. Setting USA. Participants Smokers (n=94) from 26 states were enrolled (mean age 36, 56% female). Intervention and comparator Participants were randomized to earn financial incentives (up to $480 over 7 weeks) based on video-verified abstinence using breath carbon monoxide (CO) output (n=48; Abstinent Contingent Group, AC), or based on submitting CO samples (n=46, Submission Contingent, SC). Both groups also received the same CO-based goals. A $50 deposit was required in both groups that could be recouped from initial earnings. Measures The primary outcome was point prevalence at week 4. Secondary outcomes were point prevalence at the 3- and 6-month follow-ups, percentages of negative CO samples, adherence to the CO sampling protocol, and treatment acceptability ratings on a 0–100mm visual analog scale. Findings Abstinence rates differed at 4 weeks between the AC (39.6%) and SC (13.0%) groups (odds ratio=4.4, 95% CI=1.6–12.3), but not at the 3- (29.2% AC and 19.6% SC, odds ratio=1.7, 95% CI=.6–4.4), or 6- (22.9% AC and 13.0% SC, odds ratio=2.0, 95% CI=.7–5.9) month follow-ups. During the two main treatment phases, there were significant differences in negative COs (53.9% AC and 24.8% SC, odds ratio = 3.5, 95% CI=3.1–4.0; 43.4% AC and 24.6% SC, odds ratio = 2.3, 95% CI=1.6–3.4). Adherence to the CO submission protocol was equivalent (78% AC and 85% SC, difference = 7.0%, 95% CI = −10.3%–23.8%, x2=.75, p = .39). The lowest acceptability ratings were for the items assessing the deposit, whereas the highest ratings concerned the ease of the intervention, the graph of CO results, and earning money. Conclusions A contingency management/financial incentive program delivered via the Internet improved short-term abstinence rates compared with an internet program without the incentives.

Contingency management (CM) is one of the most effective behavioral interventions to promote drug abstinence, but availability of this treatment is limited. We evaluated the efficacy and acceptability of internet-based CM relative to an internet-based monitoring and goal-setting control group in a nationwide sample of cigarette smokers. Randomized controlled trial with 3- and 6-month follow-ups. United States. Smokers (n = 94) from 26 states were enrolled (mean age 36, 56% female). Participants were randomized to earn financial incentives (up to $480 over 7 weeks) based on video-verified abstinence using breath carbon monoxide (CO) output (n = 48; abstinent contingent group, AC), or based on submitting CO samples (n = 46, submission contingent, SC). Both groups also received the same CO-based goals. A $50 deposit was required in both groups that could be recouped from initial earnings. The primary outcome was point prevalence at week 4. Secondary outcomes were point prevalence at the 3- and 6-month follow-ups, percentages of negative CO samples, adherence to the CO sampling protocol, and treatment acceptability ratings on a 0-100-mm visual analog scale. Abstinence rates differed at 4 weeks between the AC (39.6%) and SC (13.0%) groups [odds ratio (OR) = 4.4, 95% confidence interval (CI) = 1.6-12.3], but not at the 3- (29.2% AC and 19.6% SC, OR = 1.7, 95% CI = 0.6-4.4) or 6- (22.9% AC and 13.0% SC, OR = 2.0, 95% CI = 0.7-5.9) month follow-ups. During the two main treatment phases, there were significant differences in negative COs (53.9% AC and 24.8% SC, OR = 3.5, 95% CI = 3.1-4.0; 43.4% AC and 24.6% SC, OR = 2.3, 95% CI = 1.6-3.4). Adherence to the CO submission protocol was equivalent (78% AC and 85% SC, difference = 7.0%, 95% CI = -10.3 to 23.8 %, F < 1, P = 0.39). The lowest acceptability ratings were for the items assessing the deposit, whereas the highest ratings concerned the ease of the intervention, the graph of CO results, and earning money. A contingency management/financial incentive program delivered via the internet improved short-term abstinence rates compared with an internet program without the incentives. © 2016 Society for the Study of Addiction.

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors. Analyses were conducted at the couple level, with IPV groups as a between-subjects couple level variable and sex as a within-subjects variable that allowed us to model and compare the outcomes of both partners while controlling for the correlated nature of the data. Analyses controlled for age, race, income, relationship duration, and gestational age. Among couples, 64% had no IPV; 23% male IPV victim only; 7% mutual IPV; 5% female IPV victim only. Relationship (F = 3.61, P < .001) and psychological (F = 3.17, P < .001) factors differed by IPV group, overall. Attachment anxiety, attachment avoidance, relationship equity, perceived partner infidelity, depression, stress, and hostility each differed by IPV profile (all P < .01). Attachment anxiety, equity, depression and stress had a significant IPV profile by sex interaction (all P < .05). Couples with mutual IPV had the least healthy relationship and psychological characteristics; couples with no IPV had the healthiest characteristics. Females in mutually violent relationships were at particularly high risk. Couple-level interventions focused on relational issues might protect young families from developing IPV behaviors.

This article reports a study of how mothers perceive the effects of intimate partner violence (IPV) during pregnancy and children's exposure to IPV: (a) Do interactional aspects of IPV have a negative impact on the fetus during pregnancy or on the newborn baby? and (b) Is there a relationship between interactional aspects of IPV and (a) children's risk of being exposed to IPV and (b) the age of the child when at risk for exposure to IPV? A representative sample of 137 IPV help-seeking mothers in Norway was interviewed. Severity of physical IPV and injury from sexual IPV increased the risk of consequences to the fetus. Frequency of physical and psychological IPV increased the likelihood of children's exposure. Duration of the partnership increased the risk of children's exposure to physical and sexual IPV. Finally, there was a negative linear association between children's age when exposed for the first time and frequency of physical and psychological IPV.

Intimate partner violence (IPV) victimization and perpetration and power imbalances in parenting partners may result in poor outcomes for parents and children. Previous work in this area has focused on the maternal experiences, neglecting to examine paternal effects. The present study aimed to elucidate the role of IPV, power, and equity in parenting and child outcomes in an urban sample of adolescent parents. 159 male and 182 female parents in a relationship were recruited through university-affiliated hospitals. Power, equity, and IPV were measured at 6 months post-partum and were used as predictors for parenting and child outcomes 12 months post-partum using general estimating equations. Gender interactions and mediation effects of depression were also assessed. Higher perceived relationship equity was related to better infant temperament (B = 0.052, SE = 0.023, p = 0.02) whereas higher partner power was related to poorer social development (B = −0.201, SE = 0.088, p = 0.02) and fine motor development (B = −0.195, SE = 0.078, p = 0.01). IPV victimization was associated with poor infant temperament (B = −2.925, SE = 1.083, p = 0.007) and lower parenting competence (B = −3.508, SE = 1.142, p = 0.002). Depression mediated the relationship between IPV and parenting and IPV and infant temperament. No gender effects were found. IPV, inequities, and power imbalances were disadvantageous for parenting and child outcomes. Our results suggest that these dynamics may negatively affect both males and females. Interventions to reduce violence in both partners and promote equity in relationships could benefit couples and their children. PMID:24781878

This paper aims to describe factors associated with HIV sero-status in young, rural South African women and the relationship between intimate partner violence (IPV) and HIV. A total of 1295 sexually active female volunteers, aged 15-26, from 70 villages were recruited to participate in a cluster randomized controlled trial of an HIV behavioural intervention. The main measures were HIV sero-status, and IPV and sexual practices measured using a questionnaire administered during baseline interviews. About 12.4% of women had HIV and 26.6% had experienced more than one episode of physical or sexual IPV. After adjusting for age, HIV infection was associated with having three or more past year partners [odds ratio (OR) 2.39; 95% confidence interval (95% CI) 1.48-3.85], sex in past 3 months (OR 3.33; 95% CI 1.87-5.94), a partner three or more years older (OR 1.69; 95% CI 1.16-2.48), and a more educated partner (OR 1.91; 95% CI 1.30-2.78). IPV was associated with HIV in two-way analyses (OR 1.56; 95% CI 1.08-2.23), but the effect was non-significant after adjusting for HIV risk behaviours. The experience of IPV was strongly associated with past year partner numbers, time of last sex, and partner's education; it was also marginally associated with partner age difference. Adverse experiences in childhood, including sexual abuse, increased the likelihood of having more past year partners (OR 1.43; 95% CI 1.21-1.69). IPV was strongly associated with most of the identified HIV risk factors. Our findings provide further evidence of links between IPV and HIV among women and the importance of joint prevention.

Intimate partner violence (IPV) and unintended pregnancy are public health issues that can affect the health and well-being of women and their children. However, the relationship between IPV and women's ability to control their fertility has not been adequately explored. To investigate the association between unintended pregnancy and emotional or physical violence perpetrated by partners around pregnancy. A population-based study was undertaken, recruiting women (n=779) at the hospital obstetric departments and gathering social and family data. IPV was diagnosed by using the Index of Spouse Abuse (ISA). Data were gathered by trained midwives in 15 public hospitals in southern Spain and multivariate logistic regression analysis was performed. The pregnancy was reported to be unintended by 118 (15.1%) of the study population. Unintended pregnancy was significantly associated with: physical and/or emotional IPV around pregnancy, age, marital status, cohabitation, educational level, and employment status. After adjusting for socio-demographic characteristics, emotional IPV around pregnancy was significantly associated with an unintended pregnancy (AOR=2.5; 95% CI=1.5-4.3). Being in a non-committed relationship was a risk factor (AOR=3.5; 95% CI=1.8-6.1) and being in employment a protective factor (AOR=0.4; 95% CI=0.2-0.8) for an unintended pregnancy. Women who report an unintended pregnancy may be experiencing emotional IPV. The risk of emotional IPV is higher if women reporting an unintended pregnancy are in a committed relationship, married, or in employment. A better understanding of the relationship between unintended pregnancy and violence can aid midwives about potential reproductive health risk factors associated with abuse.
