  1. Ambient Assistive Technologies (AAT): socio-technology as a powerful tool for facing the inevitable sociodemographic challenges?

    PubMed

    Due to the socio-demographic change in most developed western countries, elderly populations have been continuously increasing. Therefore, preventive and assistive systems that allow elderly people to independently live in their own homes as long as possible will become an economical if not ethical necessity. These respective technologies are being developed under the term "Ambient Assistive Technologies" (AAT). The EU-funded AAT-project Ambient Lighting Assistance for an Ageing Population (ALADIN) has established the long-term goal to create an adaptive system capable of improving the residential lighting conditions of single living elderly persons also aiming at supporting the preservation of their independence.Results of an earlier survey revealed that the elderly perceived their current lighting situation as satisfactory, whereas interviewers assessed in-house lighting as too dark and risk-laden. The overall results of ALADIN showed a significant increase in well-being from the baseline final testing with the new adaptive lighting system.Positive results for wellbeing and life quality suggest that the outcome effects may be attributed to the introduction of technology as well as to social contacts arising from participating in the study. The technological guidance of the study supervisors, in particular, may have produced a strong social reactivity effect that was first observed in the famous Hawthorne experiments in the 1930s. As older adults seem to benefit both from meaningful social contacts as well as assistive technologies, the question arises how assistive technology can be socially embedded to be able to maximize positive health effects. Therefore ethical guidelines for development and use of new assistive technologies for handicapped/older persons have to be developed and should be discussed with regard to their applicability in the context of AAT.

    Currently, one of the main objectives of human-animal interaction research is to demonstrate the benefits of animal assisted therapy (AAT) for specific profiles of patients or participants. The aim of this study is to assess the effect of an AAT program as an adjunct to a conventional 6-month psychosocial rehabilitation program for people with schizophrenia. Our hypothesis is that the inclusion of AAT into psychosocial rehabilitation would contribute positively to the impact of the overall program on symptomology and quality of life, and that AAT would be a positive experience for patients. To test these hypotheses, we compared pre-program with post-program scores for the Positive and Negative Syndrome Scale (PANSS) and the EuroQoL-5 dimensions questionnaire (EuroQol-5D), pre-session with post-session salivary cortisol and alpha-amylase for the last four AAT sessions, and adherence rates between different elements of the program. We conducted a randomized, controlled study in a psychiatric care center in Spain. Twenty-two institutionalized patients with chronic schizophrenia completed the 6-month rehabilitation program, which included individual psychotherapy, group therapy, a functional program (intended to improve daily functioning), a community program (intended to facilitate community reintegration) and a family program. Each member of the control group (n = 8) participated in one activity from a range of therapeutic activities that were part of the functional program. In place of this functional program activity, the AAT-treatment group (n = 14) participated in twice-weekly 1-h sessions of AAT. All participants received the same weekly total number of hours of rehabilitation. At the end of the program, both groups (control and AAT-treatment) showed significant improvements in positive and overall symptomatology, as measured with PANSS, but only the AAT-treatment group showed a significant improvement in negative symptomatology.

    Currently, one of the main objectives of human–animal interaction research is to demonstrate the benefits of animal assisted therapy (AAT) for specific profiles of patients or participants. The aim of this study is to assess the effect of an AAT program as an adjunct to a conventional 6–month psychosocial rehabilitation program for people with schizophrenia. Our hypothesis is that the inclusion of AAT into psychosocial rehabilitation would contribute positively to the impact of the overall program on symptomology and quality of life, and that AAT would be a positive experience for patients. To test these hypotheses, we compared pre–program with post–program scores for the Positive and Negative Syndrome Scale (PANSS) and the EuroQoL-5 dimensions questionnaire (EuroQol-5D), pre–session with post–session salivary cortisol and alpha–amylase for the last four AAT sessions, and adherence rates between different elements of the program. We conducted a randomized, controlled study in a psychiatric care center in Spain. Twenty–two institutionalized patients with chronic schizophrenia completed the 6–month rehabilitation program, which included individual psychotherapy, group therapy, a functional program (intended to improve daily functioning), a community program (intended to facilitate community reintegration) and a family program.

    The High Efficiency and Resolution Multi Element Spectrograph, HERMES, was an approximately $12 million dollar project to provide a new facility class instrument for the Anglo-Australian Telescope (AAT). It was commissioned in Q4 2013. This paper examines how software challenges presented by HERMES were handled, including: minimizing cost through reusing the existing AAT 2dF/AAOmega facility software as far as possible; using instrument and data simulators to ensure new software was almost ready before any hardware had been seen; extensive upgrading of our fiber data reduction software; dealing with the tighter calibration and alignment tolerances of a high-resolution spectrograph.

    2013-06-01

    Teleanalysis-remote psychoanalysis by telephone, voice over internet protocol (VoIP), or videoteleconference (VTC)-has been thought of as a distortion of the frame that cannot support authentic analytic process. Yet it can augment continuity, permit optimum frequency of analytic sessions for in-depth analytic work, and enable outreach to analysands in areas far from specialized psychoanalytic centers. Theoretical arguments against teleanalysis are presented and countered and its advantages and disadvantages discussed. Vignettes of analytic process from teleanalytic sessions are presented, and indications, contraindications, and ethical concerns are addressed. The aim is to provide material from which to judge the authenticity of analytic process supported by technology. PMID:23599507

    This study compared Hispanics' awareness of services available to acquire assistive technology and whether they actually sought help to the findings from a national sample. The study assists the field by providing information on a group largely ignored in the literature. The authors sought to answer the following research questions: Are there intergroup differences between Hispanics with disabilities and non-Hispanics with disabilities in terms of how they receive help accessing AT services? and Are there intragroup differences among Hispanics with respect to how they receive help and their awareness of available help to acquire AT? The findings suggest a large disparity between awareness of available services to acquire assistive technology and actual receipt of such services. In addition, although similar patterns were found, the Hispanics from the national sample appear more aligned with the overall sample, while the Hispanics from the Hispanic-only sample seem to be using services at higher percentages.

  11. Ultrasound in assisted reproductive technology.

    PubMed

    Porter, Misty Blanchette

    2008-05-01

    Transvaginal ultrasound-guided oocyte retrieval is the gold standard for in vitro fertilization (IVF) treatment. Despite its relative safety, oocyte retrieval is associated with risk to the adjacent pelvic organs, bleeding, and pelvic infection. The embryo transfer (ET) procedure is considered a crucial step in an IVF cycle. The success of the ET is dependent upon multiple factors including embryo quality, proper endometrial receptivity, and the technique by which the embryos are transferred. Optimizing the technique of ET would therefore provide the best chance for pregnancy. No standard evidence-based protocol exists, but ET with ultrasound guidance has been shown to significantly increase the chance of embryo implantation, an ongoing pregnancy, and a live birth and to improve the ease of transfer. Identifying appropriate ultrasound-guided simulation training techniques in ET would ensure adequate fellowship training without affecting the outcome of assisted reproductive technology cycles.

    Epigenetic modification controls gene activity without changes in the DNA sequence. The genome undergoes several phases of epigenetic programming during gametogenesis and early embryo development, coinciding with assisted reproductive technologies (ART) treatments. Imprinting disorders have been associated with ART techniques, but disentangling the influence of the ART procedures per se from the effect of the reproductive disease of the parents is a challenge. Epidemiological human studies have shown altered birthweight profiles in ART compared with spontaneously conceived singletons. Conception with cryopreserved/thawed embryos results in a higher risk of large-for-gestational-age babies, which may be due to epigenetic modification. Further animal studies have shown altered gene expression profiles in offspring conceived by ART related to altered glucose metabolism. It is controversial whether human adolescents conceived by ART have altered lipid and glucose profiles and thereby a higher long-term risk of cardiovascular disease and diabetes. This commentary describes the basic concepts of epigenetics and gives a short overview of the existing literature on the association between imprinting disorders, epigenetic modification and ART.

    Tsui, Katherine M.; Feil-Seifer, David J.; Matarić, Maja J.; Yanco, Holly A.

    Robots have been developed for several assistive technology domains, including intervention for Autism Spectrum Disorders, eldercare, and post-stroke rehabilitation. Assistive robots have also been used to promote independent living through the use of devices such as intelligent wheelchairs, assistive robotic arms, and external limb prostheses. Work in the broad field of assistive robotic technology can be divided into two major research phases: technology development, in which new devices, software, and interfaces are created; and clinical, in which assistive technology is applied to a given end-user population. Moving from technology development towards clinical applications is a significant challenge. Developing performance metrics for assistive robots poses a related set of challenges. In this paper, we survey several areas of assistive robotic technology in order to derive and demonstrate domain-specific means for evaluating the performance of such systems. We also present two case studies of applied performance measures and a discussion regarding the ubiquity of functional performance measures across the sampled domains. Finally, we present guidelines for incorporating human performance metrics into end-user evaluations of assistive robotic technologies.

  18. Recent trends in assistive technology for mobility

    PubMed Central

    2012-01-01

    Loss of physical mobility makes maximal participation in desired activities more difficult and in the worst case fully prevents participation. This paper surveys recent work in assistive technology to improve mobility for persons with a disability, drawing on examples observed during a tour of academic and industrial research sites in Europe. The underlying theme of this recent work is a more seamless integration of the capabilities of the user and the assistive technology. This improved integration spans diverse technologies, including powered wheelchairs, prosthetic limbs, functional electrical stimulation, and wearable exoskeletons. Improved integration is being accomplished in three ways: 1) improving the assistive technology mechanics; 2) improving the user-technology physical interface; and 3) sharing of control between the user and the technology. We provide an overview of these improvements in user-technology integration and discuss whether such improvements have the potential to be transformative for people with mobility impairments.

    The High Efficiency and Resolution Multi Element Spectrograph, HERMES is an optical spectrograph designed primarily for the GALAH, Galactic Archeology Survey, the first major attempt to create a detailed understanding of galaxy formation and evolution by studying the history of our own galaxy, the Milky Way1. The goal of the GALAH survey is to reconstruct the mass assembly history of the of the Milky way, through a detailed spatially tagged abundance study of one million stars in the Milky Way. The spectrograph will be based at the Anglo Australian Telescope (AAT) and be fed with the existing 2dF robotic fibre positioning system. The spectrograph uses VPH-gratings to achieve a spectral resolving power of 28,000 in standard mode and also provides a high resolution mode ranging between 40,000 to 50,000 using a slit mask. The GALAH survey requires a SNR greater than 100 aiming for a star brightness of V=14. The total spectral coverage of the four channels is about 100nm between 370 and 1000nm for up to 392 simultaneous targets within the 2 degree field of view. Current efforts are focused on manufacturing and integration. The delivery date of spectrograph at the telescope is scheduled for 2013. A performance prediction is presented and a complete overview of the status of the HERMES spectrograph is given. This paper details the following specific topics: The approach to AIT, the manufacturing and integration of the large mechanical frame, the opto-mechanical slit assembly, collimator optics and cameras, VPH gratings, cryostats, fibre cable assembly, instrument control hardware and software, data reduction.

    Dietary intake provides valuable insights for mounting intervention programs for prevention of disease. With growing concern for adolescent obesity, the need to accurately measure diet becomes imperative. Assessment among adolescents is problematic as this group has irregular eating patterns and have less enthusiasm for recording food intake. Preliminary studies among adolescents suggest that innovative use of technology may improve the accuracy of diet information from young people. In this paper, we propose a novel food record method using a mobile device that will provide an accurate account of daily food and nutrient intake among adolescents. Our approach includes the use of image analysis tools for identification and quantification of food consumption. Images obtained before and after food is consumed can be used to estimate the diet of an individual. In this paper we describe our initial results and indicate the potential of the proposed system.

    2013-01-01

    There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mobile phones and other handheld devices accessible via our haptic (touch) and audio sensory channels. We review research and innovation within the field of mobile assistive technology for the visually impaired and, in so doing, highlight the need for successful collaboration between clinical expertise, computer science, and domain users to realize fully the potential benefits of such technologies. We initially reflect on research that has been conducted to make mobile phones more accessible to people with vision loss. We then discuss innovative assistive applications designed for the visually impaired that are either delivered via mainstream devices and can be used while in motion (e.g., mobile phones) or are embedded within an environment that may be in motion (e.g., public transport) or within which the user may be in motion (e.g., smart homes).

    Disparities in assisted reproductive technologies (ARTs) outcomes have been identified among ethnic minorities when compared with their Caucasian counterparts. Minority ethnicity has been shown to be an independent predictor of lower clinical pregnancy and live birth rates in many studies. In this article, we seek to summarize the most recent literature on ethnic difference reported within ART outcomes. We will discuss potential reasons behind these disparities and further explore independent predictors and associations between ethnicity and ART success. PMID:23934696

    Development of assisted reproductive technologies (ART) for treatment of infertility poses many questions about potential involvement of the drugs used in ART in the process of ovarian carcinogenesis. The presence of other etiological factors makes the assessment of risks implied by administering these drugs rather difficult. The results obtained in the study are controversial and inconclusive, yet theoretical and epidemiological data suggest that caution is needed in IVF patients, receiving such drug therapy.

  6. Reproductive tract microbiome in assisted reproductive technologies.

    PubMed

    Franasiak, Jason M; Scott, Richard T

    2015-12-01

    The human microbiome has gained much attention recently for its role in health and disease. This interest has come as we have begun to scratch the surface of the complexity of what has been deemed to be our "second genome" through initiatives such as the Human Microbiome Project. Microbes have been hypothesized to be involved in the physiology and pathophysiology of assisted reproduction since before the first success in IVF. Although the data supporting or refuting this hypothesis remain somewhat sparse, thanks to sequencing data from the 16S rRNA subunit, we have begun to characterize the microbiome in the male and female reproductive tracts and understand how this may play a role in reproductive competence. In this review, we discuss what is known about the microbiome of the reproductive tract as it pertains to assisted reproductive technologies. PMID:26597628

    ASSISTED REPRODUCTIVE TECHNOLOGIES (ARTs) can be very helpful for certain patients, but ethical concerns have been raised about the inherent nature of specific techniques and the contexts in which many techniques are used. Physicians play important roles in supporting those who wish to become parents and in educating patients about impediments to fertilization and ways to promote conception. We discuss various ethical issues surrounding ARTs, including family relationships, informed choice, gender issues, embryo status and the commercialization of reproduction, as well as legal and policy issues. We examine the empirical evidence of the effectiveness of ARTs and suggest ways to approach ARTs in practice. PMID:11402801

    Sartori, Massimo; Reggiani, Monica; Pagello, Enrico; Lloyd, David G.

    2013-01-01

    In this paper, we use motion capture technology together with an EMG-driven musculoskeletal model of the knee joint to predict muscle behavior during human dynamic movements. We propose a muscle model based on infinitely stiff tendons and show this allows speeding up 250 times the computation of muscle force and the resulting joint moment calculation with no loss of accuracy with respect to the previously developed elastictendon model. We then integrate our previously developed method for the estimation of 3-D musculotendon kinematics in the proposed EMG-driven model. This new code enabled the creation of a standalone EMG-driven model that was implemented and run on an embedded system for applications in assistive technologies such as myoelectrically controlled prostheses and orthoses.

    1986-01-01

    We describe a research prototype software system named ASTA (Assistant for Science and Technology Analysis) that employs artificial intelligence technology to interpret radar signals and infer the probable nature of the radar system that produces them. Such analyses are of interest, for example, to engineers who wish to reverse-engineer an electronic system. Architecturally, ASTA is a multiple-process consulting expert system operating in a personal workstation environment. It comprises two principal components: an expert system that reasons using knowledge of electronic system design, radar physics, and signal analysis techniques, and a multiform-based user interface that maintains a separate database describing the complete state of interaction with the user, including a simplified user preference model, an interactive help subsystem, and a database of prior (completed or partial) analyses. These two processes are loosely coupled; that is, they operate in strictly separated namespaces, and they communicate using a mixture of synchronous (remote procedure call) and asynchronous (true) message passing. Message-based synchronization techniques are employed to assist in maintaining consistency between the two processes.

    1996-03-01

    Since 1958, NASA has been charged with actively assisting in the transfer of technologies derived from the United States space program into the industrial sector of the U.S. economy. This has historically been accomplished through technology transfer offices working independently at each NASA field center. NASA recently restructured the program to provide regional coordination, maximize efficiencies, eliminate redundancies, and capitalize on each center's fundamental technology strengths. The nation is divided into six NASA technology transfer geographical regions with each region containing one or more NASA field centers and a regional technology transfer center. The southeast region includes the states of Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee. The NASA field centers in this region are: the Marshall Space Flight Center in Huntsville, Alabama; the Kennedy Space Center in Florida; and the Stennis Space Center in Bay St. Louis, Mississippi. The centers have teamed to focus primarily on regional industries and businesses, to provide a wide range of resources for U.S. industries, including access to unique government facilities, regional workshops, and technical problem solving. Hundreds of American businesses have benefited from this new regional initiative, as evidenced by reports of over 10,500 added or saved jobs and over 988 million worth of economic impacts as a result of their technology transfer activities.

    2014-01-01

    In this study we explored the factors that affect assistive technology (AT) provision within the Navajo Nation using a qualitative approach to inquiry. Focus groups were held in which AT users discussed their awareness of AT and their need for, use of, and satisfaction with AT devices and services. Twenty-eight individuals who used wheelchairs, orthotics or prosthetics, hearing aids, communication aids, vision aids, and other AT participated in one of seven focus groups. Seven AT providers discussed the facilitators and barriers that affect AT provision. The findings revealed six themes common to both stakeholder groups and two additional themes for AT users. The central theme for AT users centered on (not) feeling understood; the central theme for AT providers revolved around the processes, activities, and roles the providers engaged in at times for different clients. Activities to increase awareness and to promote successful AT provision and satisfaction with AT devices were proposed. PMID:25147224

    PubMed

    Pinborg, Anja; Henningsen, Anna-Karina Aaris; Malchau, Sara Sofie; Loft, Anne

    2013-02-01

    Worldwide, more than 5 million children have been born after assisted reproductive technology (ART), and in many developed countries ART infants represent more than 1% of the birth cohorts. It is well known that ART children are at increased risk of congenital malformations even after adjustment for known confounders such as maternal age. The proportion of ART children is not negligible, and knowledge about the causes of the higher risk of congenital malformations is crucial to develop prevention strategies to reduce the future risk in ART children. The aim of this review is to summarize the literature on the association between ART and congenital anomalies with respect to subfertility, fertility treatment other than ART, and different ART methods including intracytoplasmic sperm injection, blastocyst culture, and cryotechniques. Trends over time in ART and congenital anomalies will also be discussed. PMID:23290686

    PubMed Central

    Collier, Abby C.; Miyagi, Shogo J.; Yamauchi, Yasuhiro; Ward, Monika A.

    2009-01-01

    The placenta plays a vital role in pregnancy by facilitating steroid passage from maternal to fetal circulation and/or direct production of hormones. Using a murine model, we demonstrated the differences in placental steroid metabolism between pregnancies conceived naturally and with assisted reproduction technologies (ART): in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). While the ovarian steroid production was similar (estrone, 17β-estradiol) or higher (estriol) in ART pregnancies compared to mating, the levels of placental estriol were significantly lower in ART group. Placentas from ART had significantly higher activities of the steroid metabolizing enzymes UDP-glucuronosyltransferase (UGT) and sulfotransferase (SULT), which in ICSI were also coupled with decreased activity of the steroid regenerating enzymes β-glucuronidase (β-G) and Aryl sulfatase (AS). Levels of steroid metabolites androstane-3α-17β-diol glucuronide and dehydroepiandrosterone sulfate were higher in fetal compared to maternal blood in ART, but not in mating. This study demonstrates that in murine ART pregnancies, higher metabolism and clearance of steroids by the placenta may seriously affect the passage of essential hormones to the fetus. If a similar phenomenon exists in humans, this could provide a plausible explanation for obstetric and neonatal complications associated with ART, including the higher incidence of low birth weight babies.

    Most students diagnosed with disabilities in Thai special education schools received assistive technologies, but this did not guarantee the greatest benefits. The purpose of this study was to survey the provision, use and needs of assistive technologies, as well as the perspectives of key informants regarding a model of providing them in special education schools. The participants were selected by the purposive sampling method, and they comprised 120 students with visual, physical, hearing or intellectual disabilities from four special education schools in Chiang Mai, Thailand; and 24 key informants such as parents or caregivers, teachers, school principals and school therapists. The instruments consisted of an assistive technology checklist and a semi-structured interview. Results showed that a category of assistive technologies was provided for students with disabilities, with the highest being “services”, followed by “media” and then “facilities”. Furthermore, mostly students with physical disabilities were provided with assistive technologies, but those with visual disabilities needed it more. Finally, the model of providing assistive technologies was composed of 5 components: Collaboration; Holistic perspective; Independent management of schools; Learning systems and a production manual for users; and Development of an assistive technology center, driven by 3 major sources such as Government and Private organizations, and Schools.

    1995-01-01

    We have used the Kuiper Airborne Observatory (KAO) and the Anglo-Australian Telescope (AAT) to investigate the nature of the filamentary radio emission from the Galactic center region. KAO observations of the FIR line and continuum emission from the radio peak G0.095+0.012 and the E2 thermal radio filament northeast of the Galactic center can be produced by numerous nearby stars with T(sub eff) approx. 35,000 K; these can account for both the FIR luminosity and the excitation of the gas. Much of the FIR continuum and most of the strong (Si II) (34.8 micron) line emission are probably produced in the ionized gas of the filament. The FIR (O III) 52 and 88 micron lines imply an electron density of a few hundred; when compared with the radio emission measure, this implies the filament is roughly tubular or somewhat flattened in the plane of the sky. The (O III) and (S III) lines show higher excitation associated with the filament, and suggest that exciting stars may be located within the filaments and/or southeast of the E2 filament. AAT observations in the near infrared (NIR) in fact reveal a nearby cluster of hot stars southeast of the E2 filament. Additional hot stars, not identifiable from their NIR spectra, are likely to be present. These stars and those in the cluster can plausibly produce the observed radio and FIR emission in the region. The morphology of the filament is not explained by existing information however.

    The High Efficiency and Resolution Multi Element Spectrograph, HERMES is an facility-class optical spectrograph for the AAT. It is designed primarily for Galactic Archeology [21], the first major attempt to create a detailed understanding of galaxy formation and evolution by studying the history of our own galaxy, the Milky Way. The goal of the GALAH survey is to reconstruct the mass assembly history of the of the Milky Way, through a detailed spatially tagged abundance study of one million stars. The spectrograph is based at the Anglo Australian Telescope (AAT) and is fed by the existing 2dF robotic fiber positioning system. The spectrograph uses VPH-gratings to achieve a spectral resolving power of 28,000 in standard mode and also provides a high-resolution mode ranging between 40,000 to 50,000 using a slit mask. The GALAH survey requires a SNR greater than 100 for a star brightness of V=14. The total spectral coverage of the four channels is about 100nm between 370 and 1000nm for up to 392 simultaneous targets within the 2 degree field of view. Hermes has been commissioned over 3 runs, during bright time in October, November and December 2013, in parallel with the beginning of the GALAH Pilot survey starting in November 2013. In this paper we present the first-light results from the commissioning run and the beginning of the GALAH Survey, including performance results such as throughput and resolution, as well as instrument reliability. We compare the abundance calculations from the pilot survey to those in the literature.

  20. Assisted reproductive technology in the USA: Is more regulation needed?

    PubMed

    Frith, Lucy; Blyth, Eric

    2014-10-01

    The regulation of assisted reproductive technologies is a contested area. Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA, have taken a more piecemeal approach and rely on professional guidelines and the general regulation of medical practice to govern this area. It will be argued that such a laissez-faire approach is inadequate for regulating the complex area of assisted reproductive technologies. Two key examples, reducing multiple births and registers of donors and offspring, will be considered to illustrate the effects of the regulatory structure of assisted reproductive technologies in the USA on practice. It will be concluded that the regulatory structure in the USA fails to provide an adequate mechanism for ensuring the ethical and safe conduct of ART services, and that more comprehensive regulation is required.

    Assistive Technology is used to help individuals overcome limitations produced by a disability. In rural areas, it is often difficult to establish the rehabilitation team needed to evaluate the individual and to make recommendations for the appropriate assistive technology. Teleassistive technology helps overcome this difficulty by allowing the evaluation to be performed using digital interactive teleconferencing. Current technology is unable to produce full motion video over standard rural telephone lines; however, this limitation is being reduced by the post-evaluation distribution of full motion images stored on video tape. Future plans call for a time delayed transmission of video images over standard telephone lines. The current system is capable of providing cost effective assistance to individuals with disabilities who live in rural areas. Future advances in technology will undoubtedly improve our ability to provide these services.

  8. Driving, brain injury and assistive technology.

    PubMed

    Lane, Amy K; Benoit, Dana

    2011-01-01

    Individuals with brain injury often present with cognitive, physical and emotional impairments which impact their ability to resume independence in activities of daily living. Of those activities, the resumption of driving privileges is cited as one of the greatest concerns by survivors of brain injury. The integration of driving fundamentals within the hierarchical model proposed by Keskinen represents the complexity of skills and behaviors necessary for driving. This paper provides a brief review of specific considerations concerning the driver with TBI and highlights current vehicle technology which has been developed by the automotive industry and by manufacturers of adaptive driving equipment that may facilitate the driving task. Adaptive equipment technology allows for compensation of a variety of operational deficits, whereas technological advances within the automotive industry provide drivers with improved safety and information systems. However, research has not yet supported the use of such intelligent transportation systems or advanced driving systems for drivers with brain injury. Although technologies are intended to improve the safety of drivers within the general population, the potential of negative consequences for drivers with brain injury must be considered. Ultimately, a comprehensive driving evaluation and training by a driving rehabilitation specialist is recommended for individuals with brain injury. An understanding of the potential impact of TBI on driving-related skills and knowledge of current adaptive equipment and technology is imperative to determine whether return-to-driving is a realistic and achievable goal for the individual with TBI.

    2015-09-01

    Ambient Assisted Living (AAL) summarizes various connected digital networked assisting technologies with the aim to support elderly and chronically ill people and to improve their quality of life. This paper defines the term AAL and shows different fields of application for AAL technologies. It illustrates the role of AAL against the background of the societal and demographic changes, of the expected growth of older people in need of care, and of the ongoing trend of singularisation of elderly. We describe medical application areas with new opportunities for the use of AAL technologies. The article highlights further the importance of the technical acceptance of these technologies by the end users, which we deem to be the most critical factor for the diffusion and use of AAL technologies in the forthcoming years.

  14. Technology Survey Assistance Tool Focusing on Their Advantages

    NASA Astrophysics Data System (ADS)

    Nishiyama, Risa; Takeuchi, Hironori; Watanabe, Hideo; Nasukawa, Tetsuya

    It is important for R&D managers, consultants, and other people seeking broad knowledge in technology fields to survey technical literature such as research papers, white papers, and technology news articles. One of the important kinds of information for those people regards the effectiveness of new technologies in their own businesses. General search engines are good at selecting documents revealing the details of a specific technology or a technology field, but it is hard to obtain useful information about how a technology will apply to individual business cases from such search results. There is a need for a technology survey assistance tool that helps users find technologies with suitable capabilities. In this paper, two technical tasks were tackled to develop the prototype of this assistance tool: Extraction of advantage phrases and scoring for the advantage phrases to find novel applications in the target technology field. We describe a new method to identify advantage phrases in technical documents and our scoring function that gives higher scores to novel applications of the technology. The results of evaluations showed our phrase identification method with only a few phrasal patterns performs almost as well as human annotators, and the proposed scoring conforms better to the decisions made by professionals than random sort.

    Objective To compare on a population basis the birth outcomes of women treated with Assisted Reproductive Technologies (ART), women with indicators of subfertility but without ART, and fertile women. Design Longitudinal cohort study Setting Massachusetts Participants 334,628 births and fetal deaths to Massachusetts mothers giving birth in a Massachusetts hospital between July 1, 2004-December 31, 2008, subdivided into three subgroups for comparison: ART 11,271, subfertile 6,609, and fertile 316,748. Intervention None Main Outcome Measures Four outcomes: preterm birth, low birthweight, small for gestational age and perinatal death, were modeled separately for singletons and twins using logistic regression with the primary comparison between ART births and those to the newly created population based subgroup of births to women with indicators of subfertility but no ART. Results Singletons: The risks for both preterm birth and low birthweight were higher for the ART group (AOR 1.23 and 1.26, respectively) compared to the subfertile group and risks in both the ART and subfertile groups were higher than those among fertile births. Twins: the risk of perinatal death was significantly lower among ART births than fertile (AOR 0.55) or subfertile (AOR 0.15) births. Conclusions The use of a population based comparison group of subfertile births without ART demonstrated significantly higher rates of preterm birth and low birthweight in ART singleton births, but these differences are smaller than differences between ART and fertile births. Further refinement of the measurement of subfertile births and examination of the independent risks of subfertile births is warranted. PMID:25660721

  16. Commercialization of Plasma-Assisted Technologies: The Indian Experience

    NASA Astrophysics Data System (ADS)

    John, P. I.

    The paper describes an initiative by the Institute for Plasma Research (IPR), India in establishing links with the Indian industry for developing and commercialising advanced plasma-based industrial technologies. This has culminated in the creation of a self-financing technology development, incubation, demonstration and delivery facility. A business plan for converting the knowledge base to commercially viable technologies conceived technology as a product and the industry as the market and addressed issues like resistance to new technologies, the key role of entrepreneur, thrust areas and the necessity of technology incubation and delivery. Success of this strategy is discussed in a few case studies. We conclude by identifying the cost, environmental, strategic and techno-economic aspects, which would be the prime drivers for plasma-assisted manufacturing technology in India.

    2012-01-01

    We propose a novel intervention to train the speed and accuracy of attention orienting and eye movements in Autism Spectrum Disorder (ASD). Training eye movements and attention could not only affect those important functions directly, but could also result in broader improvement of social communication skills. To this end we describe a system that would allow ASD children to improve their fixation skills while playing a computer game controlled by an eye tracker. Because this intervention will probably be time consuming, this system should be designed to be used at homes. To make this possible, we propose an implementation based on wireless and dry electrooculography (EOG) technology. If successful, this system would develop an approach to therapy that would improve clinical and behavioral function in children and adults with ASD. As our initial steps in this direction, here we describe the design of a computer game to be used in this system, and the predictions of gaze position from EOG data recorded while a subject played this game.

    In this review we explore the provision of assistive technology products and services currently available for people with dementia within the United Kingdom. A scoping review of assistive technology products and services currently available highlighted 171 products or product types and 331 services. In addition, we assimilated data on the amount and quality of information provided by assistive technology services alongside assistive technology costs. We identify a range of products available across three areas: assistive technology used 'by', 'with' and 'on' people with dementia. Assistive technology provision is dominated by 'telecare' provided by local authorities, with services being subject to major variations in pricing and information provision; few currently used available resources for assistive technology in dementia. We argue that greater attention should be paid to information provision about assistive technology services across an increasingly mixed economy of dementia care providers, including primary care, local authorities, private companies and local/national assistive technology resources.

    Many factors go into appropriate recommendation and use of hearing assistive technology (HAT). The aging auditory system presents with its own complications and intricacies; there are many types of age-related hearing loss, and it is possible that the underlying cause of hearing loss can significantly impact the recommendations and performance with HATs. The audiologist should take into consideration peripheral and central auditory function when selecting HATs for the aging adult population as well as when selecting appropriate types of technology including personal sound amplification products, hearing aids, cochlear implants, and other assistive technology. The cognitive ability of the patient plays a central role in the recommendations of HAT. It is possible that the use of HATs could mitigate some of the effects of cognitive decline and thus should be considered as early as possible. Assessment of ability and appropriate recommendations are crucial to consistent use of HAT devices. PMID:27516716

    This paper provides an overview of the different legal approaches that are used in various jurisdictions to determine parental rights and obligations of the parties involved in third party assisted reproduction. Additionally, the paper explores the differing legal models that are used depending on the method of surrogacy being utilized. The data demonstrates that a given method of surrogacy may well result in different procedures and outcomes regarding parental rights in different jurisdictions. This suggests the need for a uniform method to resolve parental rights where assisted reproductive technology is involved. PMID:17073027

    Animal-assisted therapy (AAT) has been shown to be effective in the treatment of many psychological disorders, including autism spectrum disorders, depression, anxiety, and posttraumatic stress disorder (PTSD). AAT can be used as an adjunct to other forms of psychotherapy. With AAT, the animal becomes a part of the treatment plan. Outcomes for clients that are associated with the use of AAT include (1) increased sense of comfort and safety, (2) increased motivation, (3) enhanced self-esteem, (4) increased prosocial behaviors, and (5) decreased behavioral problems. AAT provides a bridge for the therapist to develop a therapeutic relationship with a client, and the animal can provide supportive reassurance for the therapist. The amount of data that supports the benefits of AAT for the treatment of those with mental illnesses is growing, but evidence-based research that supports its use is lacking. Further research is needed. PMID:27541053

    African Animal Trypanosomiasis (AAT) is endemic in at least 37 of the 54 countries in Africa. It is estimated to cause direct and indirect losses to the livestock production industry in excess of US$ 4.5 billion per annum. A century of intervention has yielded limited success, owing largely to the extraordinary complexity of the host-parasite interaction. Trypanotolerance, which refers to the inherent ability of some African livestock breeds, notably Djallonke sheep, N'Dama cattle and West African Dwarf goats, to withstand a trypanosomiasis challenge and still remain productive without any form of therapy, is an economically sustainable option for combatting this disease. Yet trypanotolerance has not been adequately exploited in the fight against AAT. In this review, we describe new insights into the genetic basis of trypanotolerance and discuss the potential of exploring this phenomenon as an integral part of the solution for AAT, particularly, in the context of African animal production systems.

  8. Assistive technologies after stroke: self-management or fending for yourself? A focus group study

    PubMed Central

    2013-01-01

    Background Assistive Technologies, defined as “electrical or mechanical devices designed to help people recover movement” have demonstrated clinical benefits in upper-limb stroke rehabilitation. Stroke services are becoming community-based and more reliant on self-management approaches. Assistive technologies could become important tools within self-management, however, in practice, few people currently use assistive technologies. This study investigated patients’, family caregivers and health professionals’ experiences and perceptions of stroke upper-limb rehabilitation and assistive technology use and identified the barriers and facilitators to their use in supporting stroke self-management. Methods A three-day exhibition of assistive technologies was attended by 204 patients, family caregivers/friends and health professionals. Four focus groups were conducted with people purposively sampled from exhibition attendees. They included i) people with stroke who had used assistive technologies (n = 5), ii) people with stroke who had not used assistive technologies (n = 6), iii) family caregivers (n = 5) and iv) health professionals (n = 6). The audio-taped focus groups were facilitated by a moderator and observer. All participants were asked to discuss experiences, strengths, weaknesses, barriers and facilitators to using assistive technologies. Following transcription, data were analysed using thematic analysis. Results All respondents thought assistive technologies had the potential to support self-management but that this opportunity was currently unrealised. All respondents considered assistive technologies could provide a home-based solution to the need for high intensity upper-limb rehabilitation. All stakeholders also reported significant barriers to assistive technology use, related to i) device design ii) access to assistive technology information and iii) access to assistive technology provision.

    1994-11-01

    Until 1993, there were no statutes in the United States covering gestational surrogacy contracts, disposition of stored embryos and gametes, parentage of children born from donated gametes and embryos, and the inheritance rights of cryopreserved embryos of deceased donors. In March 1993, the Florida Assisted Reproductive Technology Act was passed to address some of these issues and to minimize the expense and emotional cost of related courtroom proceedings. Authors of the bill believed that motherhood of a newborn in the eyes of the law should be determined by two factors: genetic inheritance and the original intent of the woman to become the parent of record. The bill included the assumption that, in the cases of children born of gestational surrogacy, the commissioning genetic parents would be the "natural parents" of the child. Some of the reasons for legislative success of the statute include: 1) clear need for statutory guidance in cases involving reproductive technology, 2) relevance of the issue to cost containment (ie, judicial costs) in an era of health care reform, 3) careful use of scientific terminology and the support of the medical community, 4) involvement of a skilled legislative team, 5) participation of physician specialists in the development of the bill (ie, practicing gynecologists in assisted reproductive technology programs), 6) participation of the State of Florida legislative staff, and 7) consultation with appropriate lobbying groups (eg, Florida Catholic Conference). The successful legislative process that was followed to achieve passage of this bill can serve as an example for other states to emulate. PMID:7936533

    2015-07-01

    Epidemiological studies demonstrate a relationship between pathological events during foetal development and future cardiovascular risk and the term 'foetal programming of cardiovascular disease' has been coined to describe this phenomenon. The use of assisted reproductive technologies (ARTs) is growing exponentially and 2-5% of children are now born by this procedure. Emerging evidence indicates that ART represents a novel important example of foetal programming. Assisted reproductive technology may modify the cardiovascular phenotype in two ways: (i) ART involves manipulation of the early embryo which is exquisitely sensitive to environmental insults. In line with this concern, ART alters vascular and cardiac function in children and studies in mice show that ART alters the cardiovascular phenotype by epigenetic alterations related to suboptimal culture conditions. (ii) Assisted reproductive technology markedly increases the risk of foetal insults that augment cardiovascular risk in naturally conceived individuals and are expected to have similar consequences in the ART population. Given the young age of the ART population, it will take another 20-30 years before data on cardiovascular endpoints will be available. What is clear already, however, is that ART emerges as an important cardiovascular risk factor. This insight requires us to revise notions on ART's long-term safety and to engage on a debate on its future. There is an urgent need to better understand the mechanisms underpinning ART-induced alteration of the cardiovascular phenotype, improve the procedure and its long-term safety, and, while awaiting this aim, not to abandon medicine's fundamental principle of doing no harm (to future children) and use ART parsimoniously.

    Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement. PMID:24112531

    Recently many reports have been published on the use of intracytoplasmic sperm injection (ICSI) and the increased risk of congenital major malformations or syndromes. We present three cases with Goldenhar syndrome (one of them a twin pair) and one case with Rubinstein-Taybi syndrome (RTS), also a twin pair. All four female cases are derived from ICSI. Goldenhar syndrome with ICSI pregnancy has been reported previously but as far as we know, RTS has not been described in association with assisted reproductive technology (ART). The four new cases reported herein will contribute to a better understanding whether ICSI pregnancy increases congenital malformations. PMID:18759096

    Background Public interest in Assisted Reproductive Technology (ART) has remained high since the birth of the world’s first in vitro fertilization baby, Louise Brown, in the United Kingdom. ART allows scientists to manipulate the fertilization process in order to bypass some pathological obstacles such as blocked fallopian tubes and non-functioning ovaries in the females, and blocked vas deferens and low sperm count in the males. The purpose was to provide a historical outline and identify the researches that most contributed to ART. Methods A review of published experimental and clinical studies of assisted reproduction carried out at the University of Bristol library website (MetaLib®). A cross-search of seven different medical databases (AMED-Allied and Complementary Medicine Database, BIOSIS Previews on Web of Knowledge, Cochrane Library, Embase, and the Medline on Web of Knowledge, OvidSP and PubMed) was completed by using the key words to explore the major milestones and progress in the development and implementation of ART. Results A speedy advancement in the development of different assisted reproductive techniques makes infertility problem more treatable than it ever had been. Conclusion Although no other field in the medicine has integrated new knowledge into the daily practice more quickly than ART yet, there is a need for social research to counterbalance the dominance of biomedical one, in particular the people’s actual experiences and expectations of ART.

    This review, is a synopsis of advanced reproductive technologies in farm animals, including the discussion of their limiting factors as revealed by the study of offspring derived from embryos produced in vitro and through cloning. These studies show that the problems of epigenetic mis-programming, which were reported in the initial stages of assisted reproduction, still persist. The importance of whole-genome analyses, including the methylome and transcriptome, in improving embryo biotechnologies in farm animals, are discussed. Genome editing approaches for the improvement of economically-relevant traits in farm animals are also described. Efficient farm animal embryo biotechnologies, including cloning and the most recent technologies such as genome editing, will effectively complement the latest strategies to accelerate genetic improvement of farm animals.

    2009-01-01

    Radical feminists have argued for both the radical potential of assisted reproductive technology (ART) and its oppressive and damaging effects for women. This paper will address the question of what constitutes a radical feminist position on ART; I will argue that the very debate over whether ART liberates or oppresses women is misguided, and that instead the issue should be understood dialectically. Reproductive technologies are neither inherently liberating nor entirely oppressive: we can only understand the potential and effects by considering how they are actually taken up within a culture. The internal contradictions, tensions, and inconsistencies within ART and the way it is addressed within the law points to a dialectic that resists a simple reductivist understanding. PMID:19076939

    The potential doubling in the percentage of the elderly within the populations of Europe and beyond over the next decades has focused informatics research on the development Assistive Technologies and Smart Homes. However its concentration on creating a supportive home environment also has the potential for makings its users over dependent on its facilities and as a result trapped within it. This paper outlines an approach that extends the smart homes concept out into the wider community to create a smart environment that not only maintains contact with all their home-based services, but also expands these to include other facilities needed to assist them whilst on the move. This involves the convergence of physiological monitoring, communications and computing with leading-edge textile technologies, which uses a multi-layered, multi-functional clothing system as a mobile and extended variant of a smart home IP hub. In addition to variable functionality capabilities of the clothing layers in terms of thermal, shock-absorbent and other characteristics, wireless IP connectivity is provided between layers with external links typically being WiFi enabled. Health optimisation is provided by on-going lifestyle guidance/action feedback based on auto-diagnostic analysis. PMID:18560086

    A surge in knowledge and interest in reproductive biology has occurred since the advent of assisted reproductive technology (ART) in the 1960s. These innovative medical advances soon challenged societies and invited criticism. Nevertheless, ART has superseded older therapies and serves as a back-up when all else fails. There are currently 61 ART clinics in Taiwan. Thanks to a group of young physicians and scientists who have devoted great effort in catching up with the modern advances in assisted reproduction, most of the important advances in ART have been introduced to Taiwan promptly and resulted in good success rates. The complications of multifetal pregnancies as well as controversies regarding gestational surrogacy and new technologies such as intracytoplasmic sperm injection, preimplantation genetic diagnosis, and cloning have challenged conventional wisdom, ethics, laws, and religions. Society now faces a dilemma in striking a balance among science, ethics, and human rights. It is, thus, advisable that we stand back once in a while and carefully consider where we should go next.

    Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at university, in an Internet point). In this paper, we discuss how cloud computing provides a valid technological solution to enhance such a scenario.With the emergence of cloud computing, many applications are executed on top of virtual machines (VMs). Virtualization allows us to achieve a software implementation of a real computer able to execute a standard operating system and any kind of application. In this paper we propose to build personalized VMs running AT programs and settings. By using the remote desktop technology, our solution enables users to control their customized virtual desktop environment by means of an HTML5-based web interface running on any computer equipped with a browser, whenever they are.

    Yeung, Edwina H.; Druschel, Charlotte

    2013-01-01

    The cardiometabolic health of children conceived by assisted reproductive technologies (ART) compared with children conceived without medical assistance is unclear. Although the majority of published studies evaluating height, weight, and body mass index have not found differences by method of conception, some studies have indicated differences in adiposity by more direct measures such as skinfolds and dual X-ray absorptiometry. Far fewer studies have investigated other cardiometabolic characteristics, such as blood pressure and measures of lipid and glucose metabolism. Of these studies, some indications of increased blood pressure and recent findings of vascular dysfunction among children conceived by ART compared with children conceived without ART warrant further investigation. Epigenetic differences may be the global mechanism at work, resulting from different aspects of ART treatment, such as ovarian stimulation, in vitro culture, and manipulation of sperm, among other considerations. Fetal growth and placental development may serve as mediators of these effects. Future studies should consider recruiting sufficient numbers of ART and non-ART conceived multiples and collect information on indicators of cardiometabolic health in the parents. Despite some advantages of sibling cohorts in developmental origins research, its feasibility and utility for investigating health of children conceived by ART remains debatable. PMID:23312226

    A broad understanding of the numerous ion or plasma assisted surface coating/modification processes is sought. An awareness of the principles of these processes is needed before discussing in detail the ion nitriding technology. On the basis of surface modifications arising from ion or plasma energizing and interactions, it can be broadly classified as deposition of distinct overlay coatings (sputtering-dc, radio frequency, magnetron, reactive; ion plating-diode, triode) and surface property modification without forming a discrete coating (ion implantation, ion beam mixing, laser beam irradiation, ion nitriding, ion carburizing, plasma oxidation. These techniques offer a great flexibility and are capable in tailoring desirable chemical and structural surface properties independent of the bulk properties.

    2002-01-01

    The course of pregnancies and the health of children born after assisted reproductive technologies are two of the most important outcome parameters of the quality of the techniques. There is an ongoing discussion as to whether these parameters may show poorer results as compared with spontaneous conception. Recent studies have shown increased risks for the pregnancy course following conventional IVF (e.g. premature birth, low birthweight), and a higher rate of major malformations after conventional IVF as well as after intracytoplasmic sperm injection. Molecular biological studies may support the idea that these risks are not related to the techniques used, but to parental background factors. Data from surrogate motherhood also demonstrate that here the risk is lower as compared with pregnancies from IVF mothers, who carry their own child to birth. Therefore, there are more infertility related problems than those related to technique. Finally, however, a risk related to the technique itself cannot be excluded completely by currently available data. PMID:12470533

    Mahajan, Nalini; Sharma, S.

    2016-01-01

    A thin endometrium is encountered infrequently (2.4%) in assisted reproductive technology cycles. When it does occur it is a cause of concern as it is associated with lower implantation rate and pregnancy rate. Though pregnancies have been reported at 4 and 5 mm it is apparent that an endometrial thickness <6 mm is associated with a trend toward lower probability of pregnancy. Hormone replacement therapy – frozen embryo transfer (FET) cycles appear to give better results due to an improvement in endometrial receptivity (ER). The etiology of thin endometrium plays a significant part in its receptivity. A number of treatments have been tried to improve endometrial growth, but none has been validated so far. Confirming ER of a thin endometrium by an ER array test before FET offers reassurance. PMID:27110071

    Objective Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea. This study was designed to report on the current status of ART therapy in South Korea between January 1 and December 31 of 2010. Methods A revised survey, originally developed by the International Committee Monitoring Assisted Reproductive Technologies, was sent to all available ART centers via email in 2013. Fresh embryo transfer (FET) cases were categorized into standard IVF or intracytoplasmic sperm injections. These cases, the thawing embryo transfer (TET) cases, and other related procedures were surveyed. Results Data from 30,785 ART procedures were provided by 78 clinics. Of the 28,200 cycles in which oocytes were retrieved, 92.2% of these cycles were completely transferred. In addition, 8,075 cycles were confirmed to be clinical pregnancies in the FET cycles, which represent a pregnancy rate of 28.6% per oocyte pick-up and 31.1% per embryo transfer. The most common number of embryos transferred in the FET was three embryos (37.3%) followed by two embryos (36.3%) and one embryo (14.0%). Of the 6,648 TET cycles transferred, 2,356 clinical pregnancies were confirmed by ultrasonography. The most common number of embryos in the TET group was two embryos (43.4%) followed by three embryos (25.4%) and one embryo (18.9%). Conclusion The clinical pregnancy rate per transfer in the FET cycles was similar in 2009 and 2010. Among the FET cycles where one or two embryos were transferred, the clinical pregnancy rate per transfer slightly increased from 2009 (28.7%) to 2010 (32.9%). PMID:25874168

    The Fashion an Easier Lifestyle with Assistive Technology (FELAT) curriculum was developed as a needs-based, community educational program provided through a state Cooperative Extension Service. The overall goal for participants was to raise awareness of assistive technology. Program evaluation included a postassessment and subsequent interview to determine short-term knowledge gain and longer term behavior change. The sample consisted of mainly older, married females. The FELAT program was effective at raising awareness and increasing knowledge of assistive technology, and for many participants, the program acted as a catalyst for planning to or taking action related to assistive technology.

  17. Failures of reproduction: problematising 'success' in assisted reproductive technology.

    Peters, Kathleen; Jackson, Debra; Rudge, Trudy

    2007-06-01

    This paper scrutinises the many ways in which 'success' is portrayed in representing assisted reproductive technology (ART) services and illuminates how these definitions differ from those held by participant couples. A qualitative approach informed by feminist perspectives guided this study and aimed to problematise the concept of 'success' by examining literature from ART clinics, government reports on ART, and by analysing narratives of couples who have accessed ART services. As many ART services have varying definitions of 'success' and as statistics are manipulated to promote further patronage of ART services, the likelihood of 'success' is often overstated. This paper is concerned with the effects this promotion has on the participants. We suggest that this very mobilisation of statistical success changes the ability of those who access ART services to make productive decisions about themselves inside these treatment regimes, as the basis for decision-making is hidden by the way numbers, objectivity and clinical reasoning operate to maintain participation in the program. In such an operation, the powerful mix of hope and technology kept participants enrolled far longer than they originally planned. Moreover, how success rates are manipulated raises ethical issues for all involved: clients, counsellors, and nursing and medical professionals. PMID:17518824

    Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and fertility clinics. This article intended to report the status of ART in 2009 Korean Society of Obstetrics and Gynecology surveyed. The current survey was performed to assess the status and success rate of ART performed in Korea, between January 1 and December 31, 2009. Reporting forms had been sent out to IVF centers via e-mail, and collected by e-mail as well in 2012. With International Committee Monitoring Assisted Reproductive Technologies recommendation, intracytoplasmic sperm injection (ICSI) and non-ICSI cases have been categorized and also IVF-ET cases involving frozen embryo replacement have been surveyed separately. Seventy-four centers have reported the treatment cycles initiated in the year of 2009, and had performed a total of 27,947 cycles of ART treatments. Among a total of 27,947 treatment cycles, IVF and ICSI cases added up to 22,049 (78.9%), with 45.3% IVF without ICSI and 54.7% IVF with ICSI, respectively. Among the IVF and ICSI patients, patients confirmed to have achieved clinical pregnancy was 28.8% per cycle with oocyte retrieval, and 30.9% per cycle with embryo transfer. The most common number of embryos transferred in 2009 is three embryos (40.4%), followed by 2 embryos (28.4%) and a single embryo transferred (13.6%). Among IVF and ICSI cycles that resulted in multiple live births, twin pregnancy rate was 45.3% and triple pregnancy rate was 1.1%. A total of 191 cases of oocyte donation had been performed to result in 25.0% of live birth rate.

    technologies that have the potential to improve efficiency of livestock production. The focus will be on technologies that manipulate male and female gametes as well as the stem cells from which they are derived and the preimplantation embryo. While technology is crucial to other interventions in the reproductive process like control of seasonal breeding, hormonal regulation of ovulation, estrous cyclicity and pregnancy establishment, feeding to optimize reproduction, minimizing environmental stress, and selection of genes controlling reproduction, these will not be considered here. Rather the reader is directed to other chapters in this volume as well as some reviews on other aspects of artificial manipulation of reproduction (Reprod Fertil Dev 24:258-266, 2011; Reprod Domest Anim 43:40-47, 2008; Reprod Domest Anim 43:122-128, 2008; Soc Reprod Fertil Suppl 66:87-102, 2009; Comprehensive biotechnology, Amsterdam, pp 477-485; Dairy production medicine, Chichester, pp 153-163; Theriogenology 76:1619-1631, 2011; Theriogenology 76:1568-1582, 2011; Theriogenology 77:1-11, 2012). Given the large number of mammalian species used for production of products useful for man and the diversity in their biology and management, the review will not be comprehensive but instead will use results from species that are most illustrative of the opportunities generated by assisted reproductive technologies.

    Introduction This study illustrated the global contribution to assisted reproductive technologies (ARTs) research in MEDLINE database from 1998 to 2014. Methods In March 2015, the MEDLINE database was searched for research publications indexed under ‘reproductive techniques, assisted’ (including the following MeSH headings: in vitro fertilization [IVF]; intracytoplasmic sperm injections; cryopreservation; and ovulation induction), with the following expressions in the fields of title or abstract: intrauterine insemination; sperm donation; embryo/egg donation and surrogate mothers. The number of publications in MEDLINE database was recorded for each individual year, 1998–2014, and for each country. The following countries were arbitrarily selected for data retrieval: United States, United Kingdom, France, Germany, Canada, Italy, Japan (G7 countries), Brazil, Russia, India, China (BRIC countries), Egypt, Turkey, Israel and Iran. Results The absolute number of publications for each country from 1998 to 2014 ranged from 75 to 16453, with a median of 2024. The top five countries were the US (16453 publications), the UK (5427 publications), Japan (4805), China (4660) and France (3795). ART (20277), cryopreservation (11623) and IVF (11209) were the most researched areas. Conclusion Global research on ARTs were geographically distributed and highly concentrated among the world’s richest countries. Cryopreservation and IVF were the most productive research domains among ARTs. PMID:26813255

    Abstract Previous study has shown that in the United States, most maternal deaths and severe obstetric complications due to chronic disease are potentially preventable through improved medical care before conception. Many women who need assisted reproductive technology (ART) because of infertility are older than the average pregnant woman. Risks for such chronic diseases as obesity, diabetes mellitus, chronic hypertension, cardiovascular disease (CVD), and malignancy greatly increase with maternal age. Chronic illness increases the risk of the in vitro fertilization (IVF) procedure and is also associated with increased obstetric risk and even death. The objective of this review is to outline the potential risks for older women who undergo ART procedures and pregnancy and to characterize guidelines for evaluation before enrollment in ART programs. A PubMed search revealed that very few studies have related to pre-ART medical evaluation. Therefore, we suggest a pre-ART medical assessment, comparable to the recommendations of the American Heart Association before noncompetitive physical activity and the American Society of Anesthesiologists before elective surgery. This assessment should include a thorough medical questionnaire and medical examination. Further evaluation and treatment should follow to ensure the safety of ART procedures and of ensuing pregnancies. PMID:21510806

    Tongue control with low profile, passive mouth tags is demonstrated as a human-device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed targets. The rate at which users are able to learn accurate targeting with high accuracy indicates that this is an intuitive device to operate. The significance of the work is that innovative very unobtrusive, wireless tags can be used to provide intuitive human-computer interfaces based on low cost and disposable mouth mounted technology. With the development of an appropriate reading system, control of assistive devices such as computer mice or wheelchairs could be possible for tetraplegics and others who retain fine motor control capability of their tongues. The tags contain no battery and are intended to fit directly on the hard palate, detecting tongue position in the mouth with no need for tongue piercings. PMID:27222736

    2014-01-01

    According to the WHO, infertility and sterility will be the third-most serious disease worldwide in the 21st century, after cancer and cardiovascular diseases. In contrast to developed countries, assisted reproductive technology (ART) were not offered in China until the mid-1980s with the first in vitro fertilization (IVF) infant born in Taiwan in 1985, then Hong Kong in 1986, and mainland China in 1988, respectively. Since those inceptions, the practice of ART in China has evoked a variety of social, cultural, political and one-child policy responses that have resulted in restrictions on the number of IVF cycles performed annually. According to recent survey, an estimate 40-50 million women and 45 million men suffered from infertility, which is estimated that more than ten million Chinese infertile couples require ART treatment. However, it has limited access to ART facilities, many of them may not have a child are whirling to all types of fertility therapies. Exposure to radiation, pesticides and other environmental pollutants, work-related stress and unhealthy lifestyles are believed to contribute to the increasing incidence of infertility in China. The aim of this first report is to provide China nationwide ART data and government policy in compliance and 
non-compliance, particularly related to family plan policy in China. PMID:26835327

    Dias, Renuka P; Maher, Eamonn R

    2013-06-01

    Genomic imprinting is a parent-of-origin allele-specific epigenetic process that is critical for normal development and health. The establishment and maintenance of normal imprinting is dependent on both cis-acting imprinting control centers, which are marked by differentially (parental allele specific) methylated marks, and trans mechanisms, which regulate the establishment and/or maintenance of the correct methylation epigenotype at the imprinting control centers. Studies of rare human imprinting disorders such as familial hydatidiform mole, Beckwith-Wiedemann syndrome and familial transient neonatal diabetes mellitus have enabled the identification of genetic (e.g., mutations in KHDC3L [C6ORF221], NLRP2 [NALP2], NLRP7 [NALP7] and ZFP57) and environmental (assisted reproductive technologies) factors that can disturb the normal trans mechanisms for imprinting establishment and/or maintenance. Here we review the clinical and molecular aspects of these imprinting disorders in order to demonstrate how the study of rare inherited disorders can illuminate the molecular characteristics of fundamental epigenetic processes, such as genomic imprinting.

    There have been increased incident reports of rare imprinting disorders associated with assisted reproductive technology (ART). ART is an important treatment for infertile people of reproductive age and is increasingly common. The identification of epigenetic changes at imprinted loci in ART infants has led to the suggestion that the techniques themselves may predispose embryos to acquisition of imprinting errors and disease. It is still unknown, however, at what point(s) these imprinting errors arise, or the risk factors. In this review it was hypothesized that the particular steps of the ART process may be prone to induction of imprinting methylation errors during gametogenesis, fertilization and early embryonic development. In addition, imprinting diseases and their causes are explained. Moreover, using a Japanese nationwide epidemiological study of imprinting diseases, their association with ART is determined. Epigenetic studies are required to understand the pathogenesis of this association; the ART-related risk factor(s); and the precautions that can be taken to prevent the occurrence of these syndromes. It is hoped that the constitution of children born after ART will indicate the safest and most ethical approach to use, which will be invaluable for the future development of standard ART treatment.

    2012-01-01

    Mobility is frequently described in terms of individual body function and structures however contemporary views of disability also recognise the role of environment in creating disability. Aim. To identify consumer perspectives regarding barriers and facilitators to optimal mobility for a heterogeneous population of impaired Victorians who use assistive technology in their daily lives. Method. An accessible survey investigated the impact of supports or facilitators upon actual and desired life outcomes and health-related quality of life, from 100 AT users in Victoria, Australia. This paper reports upon data pertaining to community mobility. Results. A range of barriers and enablers to community mobility were identified including access to AT devices, environmental interventions, public transport, and inclusive community environs. Substantial levels of unmet need result in limited personal mobility and community participation. Outcomes fall short of many principles enshrined in current policy and human rights frameworks. Conclusion. AT devices as well as accessible and inclusive home and community environs are essential to maximizing mobility for many. Given the impact of the environment upon the capacity of individuals to realise community mobility, this raises the question as to whether rehabilitation practitioners, as well as prescribing AT devices, should work to build accessible communities via systemic advocacy.

    2013-01-01

    Tongue Drive System (TDS) is a new assistive technology that enables individuals with severe disabilities such as those with spinal cord injury (SCI) to regain environmental control using their tongue motion. We have developed a new sensor signal processing (SSP) algorithm which uses four 3-axial magneto-resistive sensor outputs to accurately detect and classify between seven different user-control commands in stationary as well as mobile conditions. The new algorithm employs a two-stage classification method with a combination of 9 classifiers to discriminate between 4 commands on the left or right side of the oral cavity (one neutral command shared on both sides). Evaluation of the new SSP algorithm on five able-bodied subjects resulted in true positive rates in the range of 70–99% with corresponding false positive rates in the range of 5–7%, showing a notable improvement in the resulted true-false (TF) differences when compared to the previous algorithm.

  7. How to avoid multiple pregnancies in assistive reproductive technologies.

    PubMed

    Cohen, J; Jones, H W

    2001-09-01

    Since 1980, there has been a worldwide dramatic increase in multiple births. This seems to be due to an increase in the age of reproduction, the use of ovulation induction, and the use of in vitro fertilization. Scarce data suggest that each of these causes is responsible for about one-third of the problem, although quintuplets and more are almost invariably due to ovulation induction. There has been little or no effort to issue guidelines or regulations with respect to ovulation induction, but there has been much advice as to how to control the problem in in vitro fertilization by limiting the number of embryos to be transferred. In sum, a good selection of high-quality embryos on day 3 would allow a high rate of pregnancy with the transfer of one or two blastocysts. Good results of cryopreservation must be part of an agreement in an in vitro fertilization program. If singleton live birthrates were considered to be the principal outcome of assisted reproductive technologies reported by centers and registry, twin and triplet rates should also be reported separately. And finally, if financial considerations would not limit the cost of reimbursement to in vitro fertilization procedures, the number of procedures could be increased with fewer embryos transferred.

    The aim of this paper was to provide reliable evidence by performing a systematic review and meta-analysis for evaluating the role of acupuncture in assisted reproductive technology. All randomized controlled trials that evaluated the effects of acupuncture, including manual, electrical, and laser acupuncture (LA) techniques, on the clinical pregnancy rate (CPR) and live birth rate (LBR) of in vitro fertilization (IVF) or artificial insemination were included. The controlled groups consisted of no acupuncture and sham acupuncture groups. The sham acupuncture included sham acupuncture at acupoints, sham acupuncture at non- or inappropriate points, sham LA, and adhesive tapes. Twenty-three trials (a total of 5598 participants) were included in this paper. The pooled CPR from all acupuncture groups was significantly higher than that from all controlled groups, whereas the LBR was not significantly different between the two groups. However, the results were quite distinct when the type of control and/or different acupuncture times were examined in a sensitivity analysis. The results mainly indicate that acupuncture, especially around the time of the controlled ovarian hyperstimulation, improves pregnancy outcomes in women undergoing IVF. More positive effects from acupuncture in IVF can be expected if a more individualized acupuncture programs are used. PMID:22811747

    Team-based design courses focused on products for people with disabilities have become relatively common, in part because of training grants such as the NSF Research to Aid Persons with Disabilities course grants. An output from these courses is an annual description of courses and projects but has yet to be complied into a "best practices guide," though it could be helpful for instructors. To meet this need, we conducted a study to generate best practices for assistive technology product development courses and how to use these courses to teach students the fundamentals of innovation. A full list of recommendations is comprised in the manuscript and include identifying a client through a reliable clinical partner; allowing for transparency between the instructors, the client, and the team(s); establishing multi-disciplinary teams; using a process-oriented vs. solution-oriented product development model; using a project management software to facilitate and archive communication and outputs; facilitating client interaction through frequent communication; seeking to develop professional role confidence to inspire students' commitment to engineering and (where applicable) rehabilitation field; publishing student designs on repositories; incorporating both formal and informal education opportunities related to design; and encouraging students to submit their designs to local or national entrepreneurship competitions.

    Following an earlier review in 2007, a further review of the academic literature relating to the uses of assistive technology (AT) by children and young people was completed, covering the period 2007-2011. As in the earlier review, a tripartite taxonomy: technology uses to train or practise, technology uses to assist learning and technology uses to enable learning, was used in order to structure the findings. The key markers for research in this field and during these three years were user involvement, AT on mobile mainstream devices, the visibility of AT, technology for interaction and collaboration, new and developing interfaces and inclusive design principles. The paper concludes by locating these developments within the broader framework of the Digital Divide. PMID:24083780

  11. Technology-assisted education in graduate medical education: a review of the literature

    PubMed Central

    2011-01-01

    Studies on computer-aided instruction and web-based learning have left many questions unanswered about the most effective use of technology-assisted education in graduate medical education. Objective We conducted a review of the current medical literature to report the techniques, methods, frequency and effectiveness of technology-assisted education in graduate medical education. Methods A structured review of MEDLINE articles dealing with "Computer-Assisted Instruction," "Internet or World Wide Web," "Education" and "Medical" limited to articles published between 2002-2007 in the English language was performed. RESULTS: The two literature searches returned 679 articles; 184 met our inclusion and exclusion criteria. In 87 articles, effectiveness was measured primarily using self-reported results from a survey of subjects. Technology-assisted education was superior to traditional methods in 42 of the 64 direct comparison articles (66%, 95% CI 53-77%). Traditional teaching methods were superior to technology-assisted education in only 3/64 (5%, 95% CI 1-13%). The remaining 19 direct comparison articles showed no difference. A detailed review of the 64 comparative studies (technology-assisted education versus traditional teaching methods) also failed to identify a best method or best uses for technology-assisted education. Conclusions Technology-assisted education is used in graduate medical education across a variety of content areas and participant types. Knowledge gain was the predominant outcome measured. The majority of studies that directly compared knowledge gains in technology-assisted education to traditional teaching methods found technology-assisted education equal or superior to traditional teaching methods, though no "best methods" or "best use" was found within those studies. Only three articles were specific to Emergency Medicine, suggesting further research in our specialty is warranted. PMID:21824405

  12. Vitamin D and assisted reproduction technologies: current concepts

    PubMed Central

    2014-01-01

    Accumulating evidence from animal and human studies suggests that vitamin D is involved in many functions of the human reproductive system in both genders, but no comprehensive analysis of the potential relationship between vitamin D status and Assisted Reproduction Technologies (ART) outcomes is currently available. On this basis, the purpose of this systematic review and meta-analysis was to perform an in-depth evaluation of clinical studies assessing whether vitamin D status of patients undergoing ART could be related to cycle outcome variables. This issue is of interest considering that vitamin D deficiency is easily amenable to correction and oral vitamin D supplementation is cheap and without significant side effects. Surprisingly, no studies are currently available assessing vitamin D status among male partners of couples undergoing ART, while seven studies on vitamin D status of women undergoing controlled ovarian hyperstimulation (COH) for ART were found and included in the review. Results show that vitamin D deficiency is highly prevalent among women undergoing COH, ranging from 21% to 31% across studies conducted in Western countries and reaching 75-99% in Iranian studies. Data on vitamin D deficiency (25-hydroxyvitamin D serum levels <20 ng/ml) in relation to ART outcomes could be extracted from three studies and included in the meta-analysis, yielding a common risk ratio (RR) of 0.89 (95% CI 0.53-1.49) and showing a lower but not statistically significant likelihood of clinical pregnancy for vitamin-D-deficient women compared with vitamin-D-sufficient patients. In conclusion, there is insufficient evidence to support the routine assessment of vitamin D status to predict the clinical pregnancy rate in couples undergoing ART. The partly conflicting results of the available studies, potentially explaining the lack of statistical significance for a negative influence of vitamin D deficiency on clinical pregnancy rate, are likely secondary to confounders

    At present, the number of elderly people is rapidly increasing, which represents a significant threat in terms of their care when they fall ill. One of the most common aging diseases nowadays is dementia, whose symptoms sooner or later include loss of cognitive functioning. Cognitive disorders can vary from serious mental retardation to inability to recall things, to the loss or disorder of specific cognitive functions such as communication. These disorders not only affect the quality of people's own life but also impose a substantial burden on their families, particularly on their caregivers. Therefore, the aim of this article is to highlight the role of assistive technologies (ATs) for managing language impairments in dementia in order to improve patients' quality of life. In addition, ATs focused on training patients' memory are also mentioned, since they can help patients to maintain their language skills. Furthermore, these ATs can delay the need for institutional care, as well as significantly reduce costs on patient care. The importance of future research in the area of the development of ATs for managing the language impairments in dementia is also discussed. There is a general trend toward the personalization of patient needs and requirements in the area of ATs. For the purpose of this article, a method of literature review of available sources defining language disorders and providing characteristic features of language disorders in dementia is used. In addition, a method of comparison of different research studies exploring ATs focused on delaying language disorders in dementia in order to postpone patients' need for institutional care is also exploited.

    Assisted reproductive technologies (ART) have changed life for the past 25 years and many ethical and social issues have emerged following this new method of conception. In order to protect individuals against scientific and ethical abuses without inhibiting scientific progress, a specific legal framework is necessary. The first French law on Bioethics was voted after an extensive debate in 1994 then reviewed in 2004. This review previously scheduled every five years is currently being discussed. Legal provisions applying to ART are part of a large framework including the protection of the patients' rights and biomedical research. The key principles consist of respect for human life and ban on commercial practices of human body parts, eugenic practices and any kind of cloning. These key principles apply to ART. Donation is anonymous and free. Created in 2004, the Agence de la biomédecine is a government agency and one of the main tools of the French regulations. The missions focus on improving the quality and the safety of the management of ART. Evaluation of activities is available to all from the annual report. The agency represents the French competent authority for medical and scientific aspects of ART. Substantial differences in European legislations exist from the open-up "laissez faire" to the most restrictive one. As a consequence a large reproductive tourism has developed particularly for egg donation or surrogacy. The medical and ethical conditions of management of patients and donors represent the main critical points. In order to avoid ethical abuses, homogenization regarding the key principles is necessary in Europe. It is an opportunity to reassert that human body parts should not be a source of financial gain.

    OBJECTIVE To assess trends of tubal factor infertility and to evaluate risk of miscarriage and delivery of preterm or low birth weight (LBW) neonates among women with tubal factor infertility using assisted reproductive technology (ART). METHODS We assessed trends of tubal factor infertility among all fresh and frozen, donor, and nondonor ART cycles performed annually in the United States between 2000 and 2010 (N=1,418,774) using the National ART Surveillance System. The data set was then limited to fresh, nondonor in vitro fertilization cycles resulting in pregnancy to compare perinatal outcomes for cycles associated with tubal compared with male factor infertility. We performed bivariate and multivariable analyses controlling for maternal characteristics and calculated adjusted risk ratios (RRs) and 95% confidence intervals (CI). RESULTS The percentage of ART cycles associated with tubal factor infertility diagnoses decreased from 2000 to 2010 (26.02–14.81%). Compared with male factor infertility, tubal factor portended an increased risk of miscarriage (14.0% compared with 12.7%, adjusted RR 1.08, 95% CI 1.04–1.12); risk was increased for both early and late miscarriage. Singleton neonates born to women with tubal factor infertility had an increased risk of pre-term birth (15.8% compared with 11.6%, adjusted RR 1.27, 95% CI 1.20–1.34) and LBW (10.9% compared with 8.5%, adjusted RR 1.28, 95% CI 1.20–1.36). Significant increases in risk persisted for early and late preterm delivery and very low and moderately LBW delivery. A significantly elevated risk was also detected for twin, but not triplet, pregnancies. CONCLUSION Tubal factor infertility, which is decreasing in prevalence in the United States, is associated with an increased risk of miscarriage, preterm birth, and LBW delivery as compared with couples with male factor infertility using ART.

    Objective The number of assisted reproductive technology (ART) clinics, ART cycles, clinical pregnancy rate (CPR), and number of newborns conceived using ART have steadily increased in South Korea. This aim of this study was to describe the status of ART in South Korea between January 1 and December 31, 2011. Methods A localized online survey was created and sent to all available ART centers via email in 2015. Fresh embryo transfer (FET) cases were categorized depending on whether standard in vitro fertilization, intracytoplasmic sperm injection (ICSI), or half-ICSI procedures were used. Thawed embryo transfer (TET) and other related procedures were surveyed. Results Data from 36,990 ART procedures were provided by 74 clinics. Of the 30,410 cycles in which oocytes were retrieved, a complete transfer was performed in 91.0% (n=27,683). In addition, 9,197 cycles were confirmed to be clinical pregnancies in the FET cycles, representing a pregnancy rate of 30.2% per oocyte pick-up and 33.2% per ET. The most common number of embryos transferred in the FET procedures was three (38.1%), followed by two (34.7%) and one (14.3%). Of the 8,826 TET cycles, 3,137 clinical pregnancies (31.1%) were confirmed by ultrasonography. Conclusion While the overall clinical pregnancy rate for the TET cycles performed was lower than the rate reported in 2010 (31.1% vs. 35.4%), the overall CPR for the FET cycles was higher than in 2010 (33.2% in 2011 and 32.9% in 2010). The most common number of embryos transferred in FET cycles was three, as was the case in 2010. PMID:27104156

    With 10 vitrification lines in operation (3 on WVP in Sellafield, 1 on AVM in Marcoule and 6 on AVH in La Hague), Sellafield Ltd and Areva NC benefit from the most in-depth experience worldwide in the vitrification of highly active liquors within a framework of commercial operations. Based on the two-step process design, using a calciner and an induction-heated hot melter, which was initially deployed in Marcoule in 1978, core vitrification equipment has been continuously improved by the independent development programmes of the two companies. In March 2005, Sellafield Ltd and Areva NC signed the Vitrification Assistance Program (hereafter referred to as VAP); a co-operative project lasting 4 years during which Areva NC is to share some areas of their experience and expertise with Sellafield Ltd. Now at the halfway point of this project, this paper summarises the work performed by the VAP team to date, highlighting the early benefits and lessons learned. The following points will be developed: - Equipment delivery and preparation for implementation on WVP - Training organization and dissemination to WVP teams - Lessons learned from the early changes implemented in operations (Calciner, Melter, Dust Scrubber and Primary off gas system), and initial feedback from the first campaign using a VAP equipped line. In conclusion: The vitrification process and technology implemented at Sellafield and at La Hague, based on the two-step process, have proved to be efficient in treating high active liquor of various types. Ten lines based on this principle have been successfully operated for more than 15 years in France and in the UK. The process has also been demonstrated to be sufficiently versatile to benefit from continuous improvement and development programmes. VAP, as a complete package to support vitrification technology and knowledge transfer from AREVA NC to Sellafield Ltd, has provided the framework for fruitful technical exchanges and discussions between the two

    Short-chain esters contribute to the blend of volatiles that define the strawberry aroma. The last step in their biosynthesis involves an alcohol acyltransferase that catalyses the esterification of an acyl moiety of acyl-CoA with an alcohol. This study identified a novel strawberry alcohol acyltransferase gene (FaAAT2) whose expression pattern during fruit receptacle growth and ripening is in accordance with the production of esters throughout strawberry fruit ripening. The full-length FaAAT2 cDNA was cloned and expressed in Escherichia coli and its activity was analysed with acyl-CoA and alcohol substrates. The semi-purified FaAAT2 enzyme had activity with C1-C8 straight-chain alcohols and aromatic alcohols in the presence of acetyl-CoA. Cinnamyl alcohol was the most efficient acyl acceptor. When FaAAT2 expression was transiently downregulated in the fruit receptacle by agroinfiltration, the volatile ester production was significantly reduced in strawberry fruit. The results suggest that FaAAT2 plays a significant role in the production of esters that contribute to the final strawberry fruit flavour. PMID:22563120

    Pathogen nutrient acquisition and metabolism are critical for successful infection and colonization. However, the nutrient requirements and metabolic pathways related to pathogenesis in oomycete pathogens are unknown. In this study, we bioinformatically identified Phytophthora sojae aspartate aminotransferases (AATs), which are key enzymes that coordinate carbon and nitrogen metabolism. We demonstrated that P. sojae encodes more AATs than the analysed fungi. Some of the AATs contained additional prephenate dehydratase and/or prephenate dehydrogenase domains in their N-termini, which are unique to oomycetes. Silencing of PsAAT3, an infection-inducible expression gene, reduced P. sojae pathogenicity on soybean plants and affected the growth under N-starving condition, suggesting that PsAAT3 is involved in pathogen pathogenicity and nitrogen utilisation during infection. Our results suggest that P. sojae and other oomycete pathogens may have distinct amino acid metabolism pathways and that PsAAT3 is important for its full pathogenicity. PMID:27020161

    Due to the accelerating rate of the industry's constant innovations, more users become dependent on the most recent technology available on the market. Assistive technology is no exception, as the needs of people with disabilities are constantly changing. A retrospective transversal cohort study was designed in order to evaluate the needs of people with disabilities in relation to assistive technology, and how these needs change over time. This study compares the needs of people with disabilities over the last five years, based on the 952 participants' personal experience in the assistive technology study carried out by Puerto Rico Assistive Technology Program (PRATP) from March 2003 to March 2007. Various statistical tests were carried out in order to determine if there is a significant difference between the reported assistive technology needs and the years of the study. Test results showed a significant statistical association between participants' knowledge level of assistive technology and the years of the study. Similarly, it showed a significant difference between the priority work areas and the years of the study. Besides, statistical associations between sectors, types of disabilities, and work priorities were established in order to determine areas of need in accordance with consumers or service providers' characteristics or particular interests.

    Hematopoietic cell transplantation is curative in many patients. However, graft-versus-host disease (GVHD), triggered by alloreactive donor cells, has remained a major complication. Here, we show an inverse correlation between plasma α-1-antitrypsin (AAT) levels in human donors and the development of acute GVHD in the recipients (n = 111; P = .0006). In murine models, treatment of transplant donors with human AAT resulted in an increase in interleukin-10 messenger RNA and CD8(+)CD11c(+)CD205(+) major histocompatibility complex class II(+) dendritic cells (DCs), and the prevention or attenuation of acute GVHD in the recipients. Ablation of DCs (in AAT-treated CD11c-DTR donors) decreased CD4(+)CD25(+)FoxP3(+) regulatory T cells to one-third and abrogated the anti-GVHD effect. The graft-versus-leukemia (GVL) effect of donor cells (against A20 tumor cells) was maintained or even enhanced with AAT treatment of the donor, mediated by an expanded population of NK1.1(+), CD49B(+), CD122(+), CD335(+) NKG2D-expressing natural killer (NK) cells. Blockade of NKG2D significantly suppressed the GVL effect. Metabolic analysis showed a high glycolysis-high oxidative phosphorylation profile for NK1.1(+) cells, CD4(+)CD25(+)FoxP3(+) T cells, and CD11c(+) DCs but not for effector T cells, suggesting a cell type-specific effect of AAT. Thus, via altered metabolism, AAT exerts effective GVHD protection while enhancing GVL effects. PMID:25224412

    Social participation of People with Disability in Republic of Korea has been grown last few years. Also demand of Assistive Technology has been increased as well. Responding these needs, the public benefits of Assistive Technology Device in Republic of Korea in 2014 was USD 1.7 billion which had been increased by 27 percent during the last five years. Despite an increase in the budget, effort to build Assistive Technology Service Delivery System (ATSDS) was not enough. Therefore, Ministry of Health and Welfare in Korea decided to build ATSDS in Republic of Korea in 2009. In this paper, the process of establishing ATSDS and 2014 outcomes of ATSDS are presented in details. For more than six years efforts of establishing national-wide ATSDS, nine Assistive Technology Centers were actively running in their delivery of service in 2014. As of 2014 outcomes of ATSDS, 14,056 cases were delivered through nine Assistive Technology Centers. The presence of ATSDS proved increase in accessibility for Assistive Technology for People with Disability followed by improvement of the quality of life of them. PMID:26294599

  17. The "Second Place" Problem: Assistive Technology in Sports and (Re) Constructing Normal.

    PubMed

    Baker, D A

    2016-02-01

    Objections to the use of assistive technologies (such as prostheses) in elite sports are generally raised when the technology in question is perceived to afford the user a potentially "unfair advantage," when it is perceived as a threat to the purity of the sport, and/or when it is perceived as a precursor to a slippery slope toward undesirable changes in the sport. These objections rely on being able to quantify standards of "normal" within a sport so that changes attributed to the use of assistive technology can be judged as causing a significant deviation from some baseline standard. This holds athletes using assistive technologies accountable to standards that restrict their opportunities to achieve greatness, while athletes who do not use assistive technologies are able to push beyond the boundaries of these standards without moral scrutiny. This paper explores how constructions of fairness and "normality" impact athletes who use assistive technology to compete in a sporting venue traditionally populated with "able-bodied" competitors. It argues that the dynamic and obfuscated construction of "normal" standards in elite sports should move away from using body performance as the measuring stick of "normal," toward alternate forms of constructing norms such as defining, quantifying, and regulating the mechanical actions that constitute the critical components of a sport. Though framed within the context of elite sports, this paper can be interpreted more broadly to consider problems with defining "normal" bodies in a society in which technologies are constantly changing our abilities and expectations of what normal means.

    Morgan, Kevin; Marsters, Peter; Morley, Stephen; van Gent, Diana; Hejazi, Ala; Backx, Matt; Thorpe, Emma R K; Kalsheker, Noor

    2002-01-01

    alpha(1)-Antitrypsin (AAT) is the major serine proteinase inhibitor (SERPIN A1) in human plasma. Its target proteinase is neutrophil elastase and its main physiological function is protection of the lower respiratory tract from the destructive effects of neutrophil elastase during an inflammatory response. Circulating levels of AAT rise 2-3-fold during inflammation and the liver produces most of this increase. The cytokines oncostatin M (OSM) and interleukin-6 have been shown to be mainly responsible for this effect, which is mediated via the interaction of cytokine-inducible transcription factors with regulatory elements within the gene. In the present study, we report for the first time that OSM stimulation of hepatocyte AAT occurs via an interaction between the hepatocyte promoter and an OSM-responsive element at the 3'-end of the AAT gene. This effect is mediated by the transcription factor signal transducer and activator of transcription 3 ('STAT 3') binding to an OSM-responsive element (sequence TTCTCTTAA), and this site is distinct from, but close to, a previously reported interleukin-6-responsive element.

  12. A review of conceptual models for assistive technology outcomes research and practice.

    PubMed

    Lenker, James A; Paquet, Victor L

    2003-01-01

    Conceptual models provide a theoretical basis for advancing scientific knowledge and improving professional practice. Although numerous assistive technology-related models have appeared in the literature, there has been no systematic effort to assess them. Six conceptual models are reviewed here: Cook and Hussey's Human-Activity-Assistive Technology model; the World Health Organization's International Classification of Functioning, Disability, and Health; Scherer's Matching Person and Technology model; Gitlin's model of an AT user's "career"; social cognition decision-making theories; and Rogers' Perceived Attributes Theory. The models are reviewed in terms of six domains: background and goals; descriptive characteristics; indication of outcome measures; predictive characteristics; validation in the literature; and utility to assistive technology practitioners, developers, and consumers. The salient strengths and limitations are highlighted for each. Application of the models to advance theory, research, and practice is discussed. PMID:14760977

    2015-07-01

    With the evolution of transcatheter valve replacement, an important opportunity has arisen for cardiologists and surgeons to collaborate in identifying the criteria for performing these procedures. Therefore, The Society for Cardiovascular Angiography and Interventions (SCAI), American Association for Thoracic Surgery (AATS), American College of Cardiology (ACC), and The Society of Thoracic Surgeons (STS) have partnered to provide recommendations for institutions to assess their potential for instituting and/or maintaining a transcatheter valve program. This article concerns transcatheter pulmonic valve replacement (tPVR). tPVR procedures are in their infancy with few reports available on which to base an expert consensus statement. Therefore, many of these recommendations are based on expert consensus and the few reports available. As the procedures evolve, technology advances, experience grows, and more data accumulate, there will certainly be a need to update this consensus statement. The writing committee and participating societies believe that the recommendations in this report serve as appropriate requisites. In some ways, these recommendations apply to institutions more than to individuals. There is a strong consensus that these new valve therapies are best performed using a Heart Team approach; thus, these credentialing criteria should be applied at the institutional level. Partnering societies used the ACC's policy on relationships with industry (RWI) and other entities to author this document (http://www.acc.org/guidelines/about-guidelines-and-clinical-documents). To avoid actual, potential, or perceived conflicts of interest due to industry relationships or personal interests, all members of the writing committee, as well as peer reviewers of the document, were asked to disclose all current healthcare-related relationships including those existing 12 months before the initiation of the writing effort.

  14. Field Test of Advanced Duct-Sealing Technologies Within the Weatherization Assistance Program

    SciTech Connect

    Ternes, MP

    2001-12-05

    A field test of an aerosol-spray duct-sealing technology and a conventional, best-practice approach was performed in 80 homes to determine the efficacy and programmatic needs of the duct-sealing technologies as applied in the U.S. Department of Energy Weatherization Assistance Program. The field test was performed in five states: Iowa, Virginia, Washington, West Virginia, and Wyoming. The study found that, compared with the best-practice approach, the aerosol-spray technology is 50% more effective at sealing duct leaks and can potentially reduce labor time and costs for duct sealing by 70%, or almost 4 crew-hours. Further study to encourage and promote use of the aerosol-spray technology within the Weatherization Assistance Program is recommended. A pilot test of full production weatherization programs using the aerosol-spray technology is recommended to develop approaches for integrating this technology with other energy conservation measures and minimizing impacts on weatherization agency logistics. In order to allow or improve adoption of the aerosol spray technology within the Weatherization Assistance Program, issues must be addressed concerning equipment costs, use of the technology under franchise arrangements with Aeroseal, Inc. (the holders of an exclusive license to use this technology), software used to control the equipment, safety, and training. Application testing of the aerosol-spray technology in mobile homes is also recommended.

  1. Evaluating Three Interface Technologies in Assisting PEDESTRIANS' Spatial Knowledge Acquisition

    NASA Astrophysics Data System (ADS)

    Huang, H.; Schmidt, M.; Gartner, G.

    2012-07-01

    Recent years have seen raising interests in mobile pedestrian navigation systems. Different interface technologies can be used to communicate/convey route directions to pedestrians, such as mobile maps, voices, and augmented reality (AR). Many field experiments have been conducted to study the effectiveness of different interface technologies in guiding pedestrians to their destinations. In contrast to other field studies, this article aims at investigating the influence of different interface technologies on spatial knowledge acquisition (spatial learning). With sufficient spatial knowledge about an environment, people can still find their way when navigation systems fail (e.g. out of battery). The goal of this article is to empirically evaluate three GPS-based navigation prototypes (implementing mobile map-based, AR-based, and voice-based guidance respectively) in supporting spatial knowledge acquisition. The field test showed that in terms of spatial knowledge acquisition, the three interface technologies led to comparable poor results, which were also not significantly different from each other. This article concludes with some implications for designing mobile pedestrian navigation systems.

    Emerging technologies provide the opportunity to develop innovative sustainable service models, capable of supporting adults with dementia at home. Devices range from simple stand-alone components that can generate a responsive alarm call to complex interoperable systems that even can be remotely controlled. From these complex systems the paradigm of the ubiquitous or ambient smart home has emerged, integrating technology, environmental design and traditional care provision. The service context is often complex, involving a variety of stakeholders and a range of interested agencies. Against this backdrop, as anecdotal evidence and government policies spawn further innovation it is critical that due consideration is given to the potential ethical ramifications at an individual, organisational and societal level. Well-grounded ethical thinking and proactive ethical responses to this innovation are required. Explicit policy and practice should therefore emerge which engenders confidence in existing supported living option schemes for adults with dementia and informs further innovation.

    The desire of geolocation and navigation technologies that provide precise, fast and reliable geo-services has exploded in the recent years, and there is a dramatic increase in the geo-service market varies from mass market applications to the new and innovative applications. The lack of reliable GNSS signals in the NLOS environment confronts many innovative ideas related to mass market location-based applications. But there is an optimized way to provide the ubiquitous geolocation services via exploitation of signals of opportunity (SoOP). The core concept of ubiquitous geolocation and navigation is provide globally available geo-services by giving the mobile terminal the ability to acquire their location information, this technology can be applied at all scales geo-reference by sharing some simple, inexpensive, robust geolocation and navigation algorisms for different technology such as GNSS and other emerging technology, and the goals of the ubiquitous geolocation and navigation service are reliable availability, transparency, seamlessness, awareness, and trustworthiness. SoOP are primarily envisioned to be man-made radio emitters not originally intended for geolocation and navigation, but may be extended to active beacons purposely deployed in an emergency situation, in this paper, we also regarded the signals of different wireless network those defined by the IEEE 802.11, IEEE 802.15 and IEEE 802.16 as an important part of SoOP. The use of widely available, powerful, and economically important SoOP in Hong Kong will provide a robust geolocation and navigation capability. We made some initial investigation into the use of the SoOP through feasibility studies and prototype investigations of the use of wireless local area network (WLAN), ultra-wide band (UWB) and ZigBee.

    Advances in underwater technology are revealing a world hitherto unseen - the deep ocean. Advances in web technology are enabling scientists to share their discoveries with the world. Underwater robot cameras are allowing scientists to observe animal behaviour and study habitats at depths of 6000 metres. And the Internet is providing a window on this exotic world for everyone with access to the web. The UK's National Oceanography Centre, Southampton operates Isis, a scientific deep-diving remotely-operated vehicle (ROV). The results are phenomenal, producing footage of life in the abyss and the ability to take samples and conduct experiments on the ocean floor. The Centre also hosts a novel project making use of the robot cameras used in the oil and gas industry for maintenance and exploration. Scientists are using this equipment during stand-by time to study animals in their own habitat. The SERPENT project - Scientific and Environmental ROV Partnership using Existing industrial Technology - is an international collaboration with industry, academia and museums. The SERPENT website is updated with the latest information and images attracting some 2000 visitors a month, which is set to rise with recent web developments. A vital part of the Centre's role is communication with the public to increase awareness of the marine environment. Images are essential for outreach especially as audiences continue to seek pictures from remote and inaccessible locations. This talk will explore how TV and the Internet are changing science outreach and the new challenges that it brings.

    2016-09-01

    Nowadays, there is a growing demand for a cleaner, but still effective alternative for production processes like in the leather industry. Ultrasound (US) assisted processing of leather might be promising in this sense. In the present paper, the use of US in the conventional chrome tanning process has been studied at different pH, temperature, tanning time, chrome dose and US exposure time by exposing the skin before tanning and during tanning operation. Both prior exposure of the skin to US and US during tanning improves the chrome uptake and reduces the shrinkage significantly. Prior exposure of the skin to US increase the chrome uptake by 13.8% or reduces the chrome dose from 8% to 5% (% based on skin weight) and shorten the process time by half while US during tanning increases the chrome uptake by 28.5% or reduces the chrome dose from 8% to 4% (half) and the tanning time to one third compared to the control without US. Concomitantly, the resulting leather quality (measured as skin shrinkage) improved from 5.2% to 3.2% shrinkage in the skin exposed to US prior tanning and to 1.3% in the skin exposed to US during the tanning experiment. This study confirms that US chrome tanning is an effective and eco-friendly tanning process which can produce a better quality leather product in a shorter process time with a lower chromium dose.

    PubMed

    Abuahmad, H

    2015-06-01

    This paper does not necessarily reflect the views of the International Commission on Radiological Protection. Naturally occurring radioactive material (NORM) is produced during exploration and production operations of subsidiaries of the Abu Dhabi National Oil Company (ADNOC) in the United Arab Emirates, and accumulates in drilling tubulars, plant equipment, and components. These NORM hazardous wastes need to be managed in such a way that they do not damage human health and the environment. The primary radionuclides of concern in the oil and gas industries are radium-226 and radium-228. These radioisotopes are the decay products of uranium and thorium isotopes that are present in subsurface formations from which hydrocarbons are produced. While uranium and thorium are largely immobile, radium is slightly more soluble and may become mobilised in the fluid phases of the formation (International Association of Oil & Gas Producers, 2008). In order to treat and dispose of NORM waste products safely, ADNOC's subsidiary 'TAKREER' is developing a new facility, on behalf of all ADNOC subsidiaries, within the existing Central Environmental Protection Facilities (BeAAT) in Ruwais city. The NORM plant is envisaged to treat, handle, and dispose of NORM waste in the forms of scale, sludge, and contaminated equipment. The NORM treatment facility will cover activities such as decontamination, volume reduction, NORM handling, and concrete immobilisation of NORM waste into packages for designated landfilling.

    2015-01-01

    Background: More and more infertile patients have accepted the assisted reproductive technique (ART) therapy. Concerns have been raised over an increased risk of adverse maternal outcomes in ART populations as compared with natural conception (NC). Objective: The aim was to improve the ART in clinicial work and to reduce the incidence of pregnancy complications in ART group according to analyzing the reasons of high incidence of pregnancy complications in ART group, comparing the incidence of pregnancy complications in different controlled ovarian hyperstimulation (COH) programs and evaluating the effects of ART which attribute to adverse pregnancy outcomes. Materials and Methods: In this prospective population-based cohort study,3216 pregnant women with gestational age ≤12 weeks, regular antenatal examination,and ultrasound identification of intrauterine pregnancy were enrolled from January 2010 to June 2013. According to having ART history, the participantswere divided into two groups: ART group (contains fresh embryo transfer group or frozen-thawed embryo transfer group) and NC group. We compared the incidence of pregnancy complications between different groups and evaluated the factors which could affect the occurrence of these complications. Results: When compared to NC group, significantly increased rates of gestational diabetes mellitus (GDM) (p<0.01), preeclampsia (PE) (p<0.01) and intrahepatic cholestasis of pregnancy (ICP) (p˂0.01) were observed in ART group. There was no significant difference in the incidence of birth defect between the two groups (p=0.07). Multiple pregnancies and Gonadotropin (Gn) were risk factors in GDM, PE, and ICP.

    Nagarathnam, Karthik; Taminger, Karen M. B.

    2001-01-01

    Lasers are useful for performing operations such as joining, machining, built-up freeform fabrication, shock processing, and surface treatments. These attributes are attractive for the supportability of longer-term missions in space due to the multi-functionality of a single tool and the variety of materials that can be processed. However, current laser technology also has drawbacks for space-based applications, specifically size, power efficiency, lack of robustness, and problems processing highly reflective materials. A review of recent laser developments will be used to show how these issues may be reduced and indicate where further improvement is necessary to realize a laser-based materials processing capability in space. The broad utility of laser beams in synthesizing various classes of engineering materials will be illustrated using state-of-the art processing maps for select lightweight alloys typically found on spacecraft. With the advent of recent breakthroughs in diode-pumped solid-state lasers and fiber optic technologies, the potential to perform multiple processing techniques is increasing significantly. Lasers with suitable wavelengths and beam properties have tremendous potential for supporting future space missions to the moon, Mars and beyond.

    The federal government provides a complete range of programs and services that can assist United States (US) coal and coal-technology firms as they expand into the foreign marketplace. These programs cover the spectrum of business export needs, which include: providing assistance in identifying target markets, locating specific business opportunities and foreign joint-venture partners, arranging business appointments, organizing trade missions, sponsoring feasibility studies, conducting trade analyses, providing financing, insuring investments, and providing in-country training and assistance. Under the sponsorship of the Department of Energy's (DOE) Office of Fossil Energy (FE), this Guide has been developed to address this problem. It is intended to provide coal and coal technology firms with a single reference source for identifying US government agencies, programs, and contacts that might aid in exporting. The Guide contains an in-depth discussion of the eight major agencies offering export assistance: the Agency for International Development (AID), the Departments of Commerce (DOC) and State (DOS), the Export-Import Bank (Eximbank), the Overseas Private Investment Corporation (OPIC), the Small Business Administration (SBA), the Trade and Development Program (TDP), and the Office of the US Trade Representative (USTR). In addition, this guide identifies pertinent activities performed by other federal agencies that might assist coal and coal-technologies exporters, including the Departments of Defense (DOD), Education, Energy (DOE), and Labor (DOL).

  20. High-Temperature Adhesives for Thermally Stable Aero-Assist Technologies

    NASA Technical Reports Server (NTRS)

    Eberts, Kenneth; Ou, Runqing

    2013-01-01

    Aero-assist technologies are used to control the velocity of exploration vehicles (EVs) when entering Earth or other planetary atmospheres. Since entry of EVs in planetary atmospheres results in significant heating, thermally stable aero-assist technologies are required to avoid the high heating rates while maintaining low mass. Polymer adhesives are used in aero-assist structures because of the need for high flexibility and good bonding between layers of polymer films or fabrics. However, current polymer adhesives cannot withstand temperatures above 400 C. This innovation utilizes nanotechnology capabilities to address this need, leading to the development of high-temperature adhesives that exhibit high thermal conductivity in addition to increased thermal decomposition temperature. Enhanced thermal conductivity will help to dissipate heat quickly and effectively to avoid temperature rising to harmful levels. This, together with increased thermal decomposition temperature, will enable the adhesives to sustain transient high-temperature conditions.

  1. Technical assistance and the transfer of remote sensing technology. [for economic development

    NASA Technical Reports Server (NTRS)

    Chipman, R.

    1977-01-01

    The transfer of technology from industrialized countries to the third world is a very complicated process and one that requires a great deal of research and development. The political and social obstacles to this transfer are generally greater than the technical obstacles, but technical assistance programs have neither the competence nor the inclination to deal with these factors adequately. Funding for technical assistance in remote sensing is now expanding rapidly, and there is a growing need for institutions to study and promote the effective use of this technology for economic development. The United Nations, the Food and Agriculture Organization, the World Bank, the United States Agency for International Development and the Canadian technical assistance agencies take different approaches to the problem and deal with the political pressures in different ways.

    2016-07-01

    New applications of information and communication technology (ICT) are shaping the way we understand and provide humanitarian medical assistance in situations of disaster, disease outbreak or conflict. Each new crisis appears to be accompanied by advancements in humanitarian technology, leading to significant improvements in the humanitarian aid sector. However, ICTs raise ethical questions that warrant attention. Focusing on the context of humanitarian medical assistance, we review key domains of ICT innovation. We then discuss ethical challenges and uncertainties associated with the development and application of new ICTs in humanitarian medical assistance, including avoiding harm, ensuring privacy and security, responding to inequalities, demonstrating respect, protecting relationships, and addressing expectations. In doing so, we emphasize the centrality of ethics in humanitarian ICT design, application and evaluation. PMID:27481835

  12. Hearing assistive technology considerations for older individuals with dual sensory loss.

    PubMed

    Kricos, Patricia B

    2007-12-01

    This article focuses on the current state of the science related to audiologic rehabilitation of individuals with dual sensory impairment, with an emphasis on considerations for provision of appropriate hearing assistive technology for this population. A substantial increase in the number of older adults is predicted in the coming years, many of whom will have significant age-related impairments in hearing and vision. Thus, hearing care professionals will be called on increasingly to attend to the special needs of people with dual sensory impairments to ensure maximal quality of life and independence for these individuals. Access to sound is critical for individuals who live with compromises in both vision and hearing. Hearing assistive technology may improve not only their speech perception but also their connection and orientation to the environment, as well as enable greater mobility. Thus, the audiologist's provision of appropriate and carefully selected hearing assistive technology may contribute dramatically to the quality of life of the individual with dual sensory loss. Prefitting, fitting, and postfitting considerations in providing hearing aids and other assistive technology to individuals with dual sensory impairment are reviewed. PMID:18080391

    OBJECTIVE To estimate trends in good perinatal outcomes (singleton live births at term with birthweight more than 2,500 g) among live births after assisted reproductive technology in the United States from 2000 to 2008, and associated factors among singletons in 2008. METHODS Using retrospective cohort data from the National Assisted Reproductive Technology Surveillance System from 2000 to 2008, we calculated relative change and χ2 tests for trend in the proportion of good perinatal outcomes among assisted reproductive technology live births (n=444,909) and liveborn singletons (n=222,500). We conducted univariable analyses followed by multiple logistic regression to estimate the effects of various characteristics on the outcome among singletons born in 2008 after fresh, nondonor assisted reproductive technology cycles (n=20,780). RESULTS The proportion of good perinatal outcomes among all liveborn neonates increased from 38.6% in 2000 to 42.5% in 2008, whereas it declined marginally among singletons from 83.6% to 83.4%. One previous birth, transfer of fewer than three embryos, and the presence of fewer than three fetal hearts on 6-week ultrasound examination were associated with good perinatal outcome among singletons. Non-Hispanic black race, tubal factor infertility, uterine factor infertility, ovulatory disorder, and 5-day embryo culture were associated with reduced odds for a good outcome. The strongest association was the presence of one fetal heart compared with more than two (adjusted odds ratio 2.43, 95% confidence interval 1.73–3.42). CONCLUSION From 2000 to 2008, good perinatal outcomes increased among assisted reproductive technology live births. Among singleton live births, odds for good outcome were greatest with the presence of a single fetal heart and lowest in women of non-Hispanic black race. LEVEL OF EVIDENCE: II PMID:22996102

    Assistive technology has the potential to enhance the level of independence of people with dementia, thereby increasing the possibility of supporting home-based care. In general, people with dementia are reluctant to change; therefore, it is important that suitable assistive technologies are selected for them. Consequently, the development of predictive models that are able to determine a person's potential to adopt a particular technology is desirable. In this paper, a predictive adoption model for a mobile phone-based video streaming system, developed for people with dementia, is presented. Taking into consideration characteristics related to a person's ability, living arrangements, and preferences, this paper discusses the development of predictive models, which were based on a number of carefully selected data mining algorithms for classification. For each, the learning on different relevant features for technology adoption has been tested, in conjunction with handling the imbalance of available data for output classes. Given our focus on providing predictive tools that could be used and interpreted by healthcare professionals, models with ease-of-use, intuitive understanding, and clear decision making processes are preferred. Predictive models have, therefore, been evaluated on a multi-criterion basis: in terms of their prediction performance, robustness, bias with regard to two types of errors and usability. Overall, the model derived from incorporating a k-Nearest-Neighbour algorithm using seven features was found to be the optimal classifier of assistive technology adoption for people with dementia (prediction accuracy 0.84 ± 0.0242).

    Abstract Introduction: More than one-third of U.S. adults are obese, which greatly increases their risks for type 2 diabetes, cardiovascular disease, and some types of cancer. Busy healthcare professionals need effective tools and strategies to facilitate healthy eating and increase physical activity, thus promoting weight loss in their patients. Communication technologies such as the Internet and mobile devices offer potentially powerful methodologies to deliver behavioral weight loss interventions, and researchers have studied a variety of technology-assisted approaches. Materials and Methods: The literature from 2002 to 2012 was systematically reviewed by examining clinical trials of technology-assisted interventions for weight loss or weight maintenance among overweight and obese adults. Results: In total, 2,011 citations from electronic databases were identified; 39 articles were eligible for inclusion. Findings suggest that the use of technology-assisted behavioral interventions, particularly those that incorporate text messaging or e-mail, may be effective for producing weight loss among overweight and obese adults. Conclusions: Only a small percentage of the 39 studies reviewed used mobile platforms such as Android® (Google, Mountain View, CA) phones or the iPhone® (Apple, Cupertino, CA), only two studies incorporated cost analysis, none was able to identify which features were most responsible for changes in outcomes, and few reported long-term outcomes. All of these areas are important foci for future research. PMID:25409001

    The environmental regulations in Czechoslovakia are being modified and will provide for more strict environmental guidelines for coal preparation, washing, mine desalination, and application of commercially viable and economical clean coal technologies for utilization of coal. The government of Czechoslovakia requested the U.S. Trade and Development Program (TDP) to carry out a Definitional Mission to Czechoslovakia to define the requirements of the country and to prepare specific recommendations for follow on actions by TDP. The technical assistance package proposed to be funded by TDP includes four specific activities. These are (i) a review of the Czech and Slovak Federal Republic (CSFR) coal characteristics, (ii) data analysis and initial matching of clean coal technologies, (iii) an orientation visit to review selected clean coal technology projects in the U.S., and (iv) preparation of a compendium of the main coal sector requirements in Czechoslovakia and the types of technologies needed. The Definitional Mission has prepared a Scope of Work which recommends that TDP allocate a fund to finance the cost of the above technical assistance activities. It is further recommended that TDP enlist the assistance of a non-profit trade organization to provide this service to the Government of Czech Republic.

    2005-09-01

    The Italian parliament passed the law on assisted reproduction after a heated debate. The promulgation of this law (Law 40/2004) is the end point of a long and troubled journey that has seen many bills come and go, all of which have failed. The law consists of a whole set of regulations that will have a great impact on health and on society in general. The law is against many of the technical practices of assisted reproduction; several such practices are banned. This paper outlines ethical and medicolegal issues arising in connection with the law. The law states that no more than three embryos must be created at any one time and all the embryos created must be transferred together even if the couple does not need all the embryos. Embryo cryopreservation is also forbidden, as is assisted reproductive technology (ART), which uses a third party in any way, and the screening of embryos for genetic defects. PMID:16131556

    The rapid development of intelligent assistive technology for replacing a human caregiver in assisting people with dementia performing activities of daily living (ADLs) promises in the reduction of care cost especially in training and hiring human caregiver. The main problem however, is the various kinds of sensing agents used in such system and is dependent on the intent (types of ADLs) and environment where the activity is performed. In this paper on overview of the potential of computer vision based sensing agent in assistive system and how it can be generalized and be invariant to various kind of ADLs and environment. We find that there exists a gap from the existing vision based human action recognition method in designing such system due to cognitive and physical impairment of people with dementia.

    Nijboer, F

    2015-02-01

    This paper provides an analysis of perspectives from different stakeholders on the state-of-the-art of BCI. Three barriers for technology transfer of BCIs as access technologies are identified. First, BCIs are developed with a narrow focus on creating a reliable technology, while a broader focus on creating a usable technology is needed. Second, the potential target group, which could benefit from BCIs as access technologies is expected to be very small. Development costs are therefore high, while reimbursements are expected to be low, which challenges the commercial viability. Third, potential target users should be much more included in the design process of BCIs to ensure that the end-products meet technical, ethical, legal and social requirements. These three issues need to be urgently addressed so that target users may benefit from this promising technology. PMID:25595535

  10. Sounding Out Science: Incorporating Audio Technology to Assist Students with Learning Differences in Science Education

    NASA Astrophysics Data System (ADS)

    Gomes, Clement V.

    With the current focus to have all students reach scientific literacy in the U.S, there exists a need to support marginalized students, such as those with Learning Disabilities/Differences (LD), to reach the same educational goals as their mainstream counterparts. This dissertation examines the benefits of using audio assistive technology on the iPad to support LD students to achieve comprehension of science vocabulary and semantics. This dissertation is composed of two papers, both of which include qualitative information supported by quantified data. The first paper, titled Using Technology to Overcome Fundamental Literacy Constraints for Students with Learning Differences to Achieve Scientific Literacy, provides quantified evidence from pretest and posttest analysis that audio technology can be beneficial for seventh grade LD students when learning new and unfamiliar science content. Analysis of observations and student interviews support the findings. The second paper, titled Time, Energy, and Motivation: Utilizing Technology to Ease Science Understanding for Students with Learning Differences, supports the importance of creating technology that is clear, audible, and easy for students to use so they benefit and desire to utilize the learning tool. Multiple correlation of Likert Survey analysis was used to identify four major items and was supported with analysis from observations of and interviews with students, parents, and educators. This study provides useful information to support the rising number of identified LD students and their parents and teachers by presenting the benefits of using audio assistive technology to learn science.

    2011-01-01

    In order to complete essential tasks, farmers with disabilities often make and use assistive technology (AT), which itself may cause further injuries known as secondary injuries. A set of 19 case studies was used to investigate the potential for injury on home-fabricated assistive technologies (ATs) used by farmers with disabilities. The case studies consisted of close-ended and open-ended interviews that were designed to help understand the farmers' perception of potential for injuries and safety measures implemented or not implemented. The qualitative study used grounded theory principles and the collected data were analyzed to arrive at a list of features on ATs that have substantial potential to cause injury to the user. Based on the case study results, AT user characteristics and environmental factors were also considered as factors that contribute to potential injuries. Findings were used to develop an instrument for use by rehabilitation professionals to evaluate ATs for potential injury causing hazards. PMID:21728872

    Historically Black College and University (HBCU) implemented new teaching methodologies that incorporate both technology and face-to-face teaching as a means of assisting and retaining the non-traditional student. Teaching strategies were enhanced through a new instructional delivery method, Tegrity. The course, Introduction to Nursing Process I, was transformed to a hybrid on-line course using Blackboard and Tegrity. Its transformation reflected inherent strengths when faculty used a systematic approach and implemented a strong team effort. A team approach including collaboration on lecture content and shared PowerPoint presentations in all sections of the course facilitated consistency in the course content. A conceptual model, which included a systems approach that encourages student involvement, was actualized throughout the project. This article utilizes a descriptive approach and explains what faculty did to retain and assist the 157 newly admitted non-traditional baccalaureate nursing students using two technological methods.

    Van Horn, A S; Reed, S A

    2001-11-01

    Couples attempting to conceive are requiring more assisted reproductive technology. Infertility may be associated with delayed onset of marriage and childbearing, smoking and alcohol excess, physiological factors such as endometriosis and varicocele, or a cause that is not identified. The psychological needs of couples, however, are often overlooked. Primary care providers can serve as the initial information source and guide for the couple struggling with infertility. In a managed care environment, a primary care provider can provide a considerable amount of education, referral for stress management and counseling, and a small portion of the medical evaluation before referring to a reproductive specialist. This overview is intended to help primary care providers and couples achieve an educated and less stressful assisted reproductive technology experience. It is not meant to circumvent the need for immediate referral to a reproductive specialist for evaluation and treatment of this very complex intervention. PMID:11725314

    Peer research was used to identify the experience and perceptions of assistive technology and telecare adoption in a UK healthcare context. A narrative account of participation and learning is intended to provoke further dialogue. There have been a range of policy and implementation initiatives that are within the direct experience of organisational actors over the last 15 years and this engagement allows for specific reflection on the service achievements and some of the barriers to implementation of technology changes in rehabilitation practice and service design. Insights are presented that suggest a reification of research priorities and a need to align technology, through patient and public engagement, to provider priorities. In addition, an improvement in adoption would be based on sustained capacity building within the Occupational Therapy workforce and a re-focus on specific knowledge sharing and learning about technology. Given the shared desire to promote the sustained adoption of appropriate technology for assistance and rehabilitation it is suggested the voice of practitioners is strengthened through research and knowledge exchange in the clinical setting.

    This special issue addresses access to and service delivery of assistive technology (AT) in resource-limited environments (RLEs). Access to AT is complicated not simply by limited funds to purchase AT, but by larger ecosystem weaknesses in RLEs related to legislation and policy, supply, distribution, human resources, consumer demand and accessible design. We present eight diverse articles that address various aspects of the AT ecosystem. These articles represent a wide range of AT, many different countries and different research methods. Our goal is to highlight a topic that has received scant research investigation and limited investment in international development efforts, and offer an insight into how different countries and programs are promoting access to AT. We encourage researchers, funders and non-profit organizations to invest additional effort and resources in this area. PMID:25955113

    The Anglo-Australian Telescope has just received a new prime- focus corrector, designed by Damien Jones (Prime Optics, Qld., Australia) and manufactured by Contraves, USA. The corrector is capable of producing aberration-corrected images over a full 2 degree diameter field of view. It is a 4-element design, the first two elements being rotatable cemented prismatic doublets approaching 1.0 m in diameter, which permit full atmospheric dispersion compensation to high zenith distances. The corrector is at the heart of a new powerful 400-fiber spectroscopic survey facility known as the 2dF. This A$2.3M project represents the largest investment in new technology and instrumentation the AAT has seen in its 20 year lifetime and will provide the telescope with a new and important role for large-scale statistical studies in the latter half of the decade and beyond. This paper will present the performance specifications for the corrector comparing them to the results of the recently complete telescope commissioning test.

    1994-01-01

    Resources and expertise on selecting assistive technology appropriate for an agricultural work setting are scarce. To meet this need a prototype knowledge system for the selection and documentation of rural assistive technology (BNG DATA) was developed to aid professionals working with farmers, ranchers, and agricultural workers with physical disabilities. The knowledge system consists of a hypertext database of technology examples and a decision support system that helps users identify solution alternatives to meet consumers' needs. End-user acceptance of BNG DATA was determined through field trials and an evaluation questionnaire administered to staff of the U.S. Department of Agriculture's AgrAbility Project. Using a statistical experiment in conjunction with the questionnaire, it was concluded that BNG DATA significantly reduced the time required by end users to find acceptable solution alternatives for consumers and increased the end users' confidence in the solutions they obtained. This manuscript describes the development and testing of BNG DATA, focusing on the selection of appropriate technology. PMID:10150739

    Background Patient access to clinical information represents a means to improve the transparency and delivery of health care as well as interactions between patients and health care providers. We examine the movement toward augmenting patient access to clinical information using technology. Our analysis focuses on “Blue Button,” a tool that many health care organizations are implementing as part of their Web-based patient portals. Objective We present a framework for evaluating the effects that technology-assisted access to clinical information may have on stakeholder experiences, processes of care, and health outcomes. Methods A case study of the United States Department of Veterans Affairs' (VA) efforts to make increasing amounts of clinical information available to patients through Blue Button. Drawing on established collaborative relationships with researchers, clinicians, and operational partners who are engaged in the VA’s ongoing implementation and evaluation efforts related to Blue Button, we assessed existing evidence and organizational practices through key informant interviews, review of documents and other available materials, and an environmental scan of published literature and the websites of other health care organizations. Results Technology-assisted access to clinical information represents a significant advance for VA patients and marks a significant change for the VA as an organization. Evaluations of Blue Button should (1) consider both processes of care and outcomes, (2) clearly define constructs of focus, (3) examine influencing factors related to the patient population and clinical context, and (4) identify potential unintended consequences. Conclusions The proposed framework can serve as a roadmap to guide subsequent research and evaluation of technology-assisted patient access to clinical information. To that end, we offer a series of related recommendations. PMID:24675395

    In recent years, new research has brought the field of electroencephalogram (EEG)-based brain–computer interfacing (BCI) out of its infancy and into a phase of relative maturity through many demonstrated prototypes such as brain-controlled wheelchairs, keyboards, and computer games. With this proof-of-concept phase in the past, the time is now ripe to focus on the development of practical BCI technologies that can be brought out of the lab and into real-world applications. In particular, we focus on the prospect of improving the lives of countless disabled individuals through a combination of BCI technology with existing assistive technologies (AT). In pursuit of more practical BCIs for use outside of the lab, in this paper, we identify four application areas where disabled individuals could greatly benefit from advancements in BCI technology, namely, “Communication and Control”, “Motor Substitution”, “Entertainment”, and “Motor Recovery”. We review the current state of the art and possible future developments, while discussing the main research issues in these four areas. In particular, we expect the most progress in the development of technologies such as hybrid BCI architectures, user–machine adaptation algorithms, the exploitation of users’ mental states for BCI reliability and confidence measures, the incorporation of principles in human–computer interaction (HCI) to improve BCI usability, and the development of novel BCI technology including better EEG devices.

    The scope of this study is to understand the use of assistive technology in the everyday life of children with disabilities, based on the concept of everyday life as a space for expression of particularity and generality of individuals. It was developed from documentary research of medical records, application of a form, observation of daily activities of children and their families and semi-structured interviews. Five children were studied, representatives in age, sex, diagnosis and use of technological resources, who were attended in primary healthcare units in São Paulo. The resources are used in homes, schools and other environments and their use is influenced by family and social relations and by the possibility of accessing products and services. It was established that the everyday activities and the use of resources are organized according to the time, space, ways in which children and, mainly, their caregivers act, showing the presence of pragmatism, economy and spontaneity typical of everyday life. The results revealed elements that can guide the practice of professionals working with assistive technology and can contribute to enable the appraisal of providing equipment in the Unified Health System.

  10. The construction of meaning by experts and would-be parents in assisted reproductive technology.

    2011-09-01

    This article explores the construction of meaning regarding assisted reproductive technology by legal framers, medical practitioners and would-be parents, through the concept of ecology of knowledge. It is argued that these inter-relationships between experts and lay people can be understood in terms of the formation of a social structure of ecology of knowledge, which depends on local and emotional knowledge co-produced by medical doctors, jurists and lay people in dynamic ways without compromising the autonomy of medical, legal and lay knowledge and skills. The assessment of the benefits and risks of assisted reproductive technology partially represents negotiations of knowledge between these social and professional groups, aiming to reproduce existing relations and practices, particularly the social power of medicine and technology, the dominant perceptions about women's and men's bodies and the geneticisation of genealogy. These negotiations of knowledge generate new rights, new social actors, new scientific fields and new ways of thinking and talking about individual and institutional responsibilities. Ecology of knowledge comes imbued with hope, trust, power, credibility of institutions and moralisation whereby some citizens' rights may be weakened. PMID:21899561

    This paper considers issues relevant for the design and use of haptic technology for assistive devices for individuals who are blind or visually impaired in some of the major areas of importance: Braille reading, tactile graphics, orientation and mobility. We show that there is a wealth of behavioral research that is highly applicable to assistive technology design. In a few cases, conclusions from behavioral experiments have been directly applied to design with positive results. Differences in brain organization and performance capabilities between individuals who are "early blind" and "late blind" from using the same tactile/haptic accommodations, such as the use of Braille, suggest the importance of training and assessing these groups individually. Practical restrictions on device design, such as performance limitations of the technology and cost, raise questions as to which aspects of these restrictions are truly important to overcome to achieve high performance. In general, this raises the question of what it means to provide functional equivalence as opposed to sensory equivalence. PMID:26336151

    The quality of life of people suffering from severe motor disabilities can benefit from the use of current assistive technology capable of ameliorating communication, house-environment management and mobility, according to the user's residual motor abilities. Brain Computer Interfaces (BCIs) are systems that can translate brain activity into signals that control external devices. Thus they can represent the only technology for severely paralyzed patients to increase or maintain their communication and control options. Here we report on a pilot study in which a system was implemented and validated to allow disabled persons to improve or recover their mobility (directly or by emulation) and communication within the surrounding environment. The system is based on a software controller that offers to the user a communication interface that is matched with the individual's residual motor abilities. Patients (n=14) with severe motor disabilities due to progressive neurodegenerative disorders were trained to use the system prototype under a rehabilitation program carried out in a house-like furnished space. All users utilized regular assistive control options (e.g., microswitches or head trackers). In addition, four subjects learned to operate the system by means of a non-invasive EEG-based BCI. This system was controlled by the subjects' voluntary modulations of EEG sensorimotor rhythms recorded on the scalp; this skill was learnt even though the subjects have not had control over their limbs for a long time. We conclude that such a prototype system, which integrates several different assistive technologies including a BCI system, can potentially facilitate the translation from pre-clinical demonstrations to a clinical useful BCI.

    There are many analysis techniques in order to analyze malicious codes. However, recently malicious codes often evade detection using stealthy obfuscation techniques, and attack computing systems. We propose an enhanced dynamic binary instrumentation using hardware-assisted virtualization technology. As a machine-level analyzer, our system can be isolated from almost the whole threats of malware, and provides single step analysis environment. Proposed system also supports rapid system call analysis environment. We implement our malware analysis system (referred as MAS) on the KVM hypervisor with Intel VT-x virtualization support. Our experiments with benchmarks show that the proposed system provides efficient analysis environment with low overhead.

    This paper provides an appraisal of countries that have legislations pertaining to assisted reproductive technologies (ART). In doing so, the paper highlights the emphasis on the protection of reproductive freedom of the couples seeking ART treatment. This belief is grounded primarily on the basic notion of liberalism that attaches primary importance to respect for individual freedom, which is the foundation of the notion of reproductive rights as understood by western standards today. The main aim of the appraisal is to see how these legislations address the drastic changes in familial relationships when ART involves the use of donated materials. PMID:23908737

    Post-traumatic orbital reconstruction remains a surgical challenge and requires careful preoperative planning, sound anatomical knowledge and good intraoperative judgment. Computer-assisted technology has the potential to reduce error and subjectivity in the management of these complex injuries. A systematic review of the literature was conducted to explore the emerging role of computer-assisted technologies in post-traumatic orbital reconstruction, in terms of functional and safety outcomes. We searched for articles comparing computer-assisted procedures with conventional surgery and studied outcomes on diplopia, enophthalmos, or procedure-related complications. Six observational studies with 273 orbits at a mean follow-up of 13 months were included. Three out of 4 studies reported significantly fewer patients with residual diplopia in the computer-assisted group, while only 1 of the 5 studies reported better improvement in enophthalmos in the assisted group. Types and incidence of complications were comparable. Study heterogeneities limiting statistical comparison by meta-analysis will be discussed. This review highlights the scarcity of data on computer-assisted technology in orbital reconstruction. The result suggests that computer-assisted technology may offer potential advantage in treating diplopia while its role remains to be confirmed in enophthalmos. Additional well-designed and powered randomized controlled trials are much needed. PMID:26643191

    Hematopoietic cell transplantation is curative in many patients. However, graft-versus-host disease (GVHD), triggered by alloreactive donor cells, has remained a major complication. Here, we show an inverse correlation between plasma α-1-antitrypsin (AAT) levels in human donors and the development of acute GVHD in the recipients (n = 111; P = .0006). In murine models, treatment of transplant donors with human AAT resulted in an increase in interleukin-10 messenger RNA and CD8+CD11c+CD205+ major histocompatibility complex class II+ dendritic cells (DCs), and the prevention or attenuation of acute GVHD in the recipients. Ablation of DCs (in AAT-treated CD11c-DTR donors) decreased CD4+CD25+FoxP3+ regulatory T cells to one-third and abrogated the anti-GVHD effect. The graft-versus-leukemia (GVL) effect of donor cells (against A20 tumor cells) was maintained or even enhanced with AAT treatment of the donor, mediated by an expanded population of NK1.1+, CD49B+, CD122+, CD335+ NKG2D-expressing natural killer (NK) cells. Blockade of NKG2D significantly suppressed the GVL effect. Metabolic analysis showed a high glycolysis–high oxidative phosphorylation profile for NK1.1+ cells, CD4+CD25+FoxP3+ T cells, and CD11c+ DCs but not for effector T cells, suggesting a cell type–specific effect of AAT. Thus, via altered metabolism, AAT exerts effective GVHD protection while enhancing GVL effects. PMID:25224412

    Currently, large amounts of thermal energy dissipated from automobiles are emitted through hot exhaust pipes. This has resulted in the need for a new efficient recycling method to recover energy from waste hot exhaust gas. The present experimental study investigated how to improve the power output of a thermoelectric generator (TEG) system assisted by a wickless loop heat pipe (loop thermosyphon) under the limited space of the exhaust gas pipeline. The present study shows a novel loop-type heat pipe-assisted TEG concept to be applied to hybrid vehicles. The operating temperature of a TEG's hot side surface should be as high as possible to maximize the Seebeck effect. The present study shows a novel TEG concept of transferring heat from the source to the sink. This technology can transfer waste heat to any local place with a loop-type heat pipe. The present TEG system with a heat pipe can transfer heat and generate an electromotive force power of around 1.3 V in the case of 170°C hot exhaust gas. Two thermoelectric modules (TEMs) for a conductive block model and four Bi2Te3 TEMs with a heat pipe-assisted model were installed in the condenser section. Heat flows to the condenser section from the evaporator section connected to the exhaust pipe. This novel TEG system with a heat pipe can be placed in any location on an automobile.

    Many factors negatively affect pregnancy establishment and subsequent fetal growth and development, including maternal factors such as nutritional stress, age, body mass index, and genetic background, and external factors including environmental stress, psychosocial stress, multiple fetuses, medical conditions (e.g., polycystic ovary syndrome), lifestyle choices (e.g., alcohol consumption, smoking), and assisted reproductive technologies. These same factors have similar consequences for placental growth and development, including vascular development. We and others have shown that placental vascular development begins very early in pregnancy and determines, to a large extent, placental function-that is, the magnitude of the increase in placental blood flow and thus nutrient transport to the fetus. During the peri-implantation period and also later in pregnancy, cloned (somatic cell nuclear transfer) embryos exhibit a variety of placental defects including reduced vascularization and altered expression of angiogenic factors. Although placental defects are less pronounced in pregnancies resulting from the transfer of in vitro fertilized embryos, we and others have recently demonstrated that vascularization, expression of angiogenic factors, sex steroid receptors, several epigenetic markers, and growth of utero-placental tissues all were altered during early pregnancy after transfer of embryos obtained through natural mating, in vitro fertilization, or other assisted reproductive techniques. These observations are in agreement with the recent reports that in humans even singleton pregnancies established with assisted reproductive techniques are at increased risk of preterm delivery and low birth weight, and seem especially relevant considering the rapidly expanding use of these techniques in humans and animals.

    Assisted reproductive technology (ART) has grown by leaps and bounds in the last few years. India has one of the highest growths in the ART centers and the number of ART cycles performed every year. Very soon India will be the leader in the world of ART in terms of a number of cycles. With the advances of technology and availability of techniques even in tier II and tier III cities our country, the results still vary dramatically. There is no standardization of protocols and reporting is very inadequate. Furthermore, there are only ART guidelines and no law still exists. Our first and the biggest challenge is to document the tremendous work being done in India and on the basis of analysis of this work, a proper registry can be made and guidance given to all on standardization and improvement. This is the 8th edition of National ART Registry of India being presented and analyzed. PMID:24672161

    A novel process to rapidly liquefy sawdust using reduced quantities of solvent, was successfully carried out via microwave-ultrasonic assisted technology (MUAT) in a sulphuric acid/polyethylene glycol 400-glycerol catalytic system. The influences of some key parameters on the liquefaction yield were investigated. The results showed that compared with traditional liquefaction, the introduction of MUAT allowed the solvent dosage to be halved and shortened the liquefaction time from 60 to 20 min. The liquefaction yield reached 91% under the optimal conditions. However, the influence on the yield of some parameters such as catalyst concentration, was similar to that of traditional liquefaction, indicating that the application of MUAT possibly only intensified heat and mass transfer rather than altering either the degradation mechanism or pathway. The introduction of MUAT as a process intensification technology has good industrial application potential for woody biomass liquefaction. PMID:26419964

    Assisted reproductive technologies (ARTS) are used for more than 30 years to help infertile couples. Concerns about long-term health of children conceived following ART have led to start follow-up studies. Despite methodological limitations and discrepant results, many of the studies and meta-analyses have reported an increased risk of birth defects after ART. Etiologies may be multiple births, a major drawback of ART, parents' subfertility, or technologies themselves. Prematurity and intrauterine growth retardation (IUGR) seem to cause most of the pathologies reported in ART children. Nevertheless, epigenetic disorders need to be followed up since increases of imprinting diseases were reported. Consequently, alteration of gametes and early embryo development with ART may have consequences on children health since periconceptional period is critical for long-term development. Yet general condition of most of children conceived with ART is reassuring, but long-term followup is still strongly needed. PMID:22778982

    Traditional methods used in optics teaching lack clarity and vividness when illustrating abstract notions such as polarization or interference. Here's where computer models may help, but they usually show only a single phenomenon or process and don't let the student see the entire picture. For this reason at Moscow Institute of Physics and Technology was developed the courseware 'Wave Optics on the Computer' consisting of a number of related simulations. It is intended for students studying optics at the Universities. Recently we have developed different simulations in optics for secondary school level. They are included as part of large computer courseware 'Physics by Pictures'. The courseware 'Wave Optics on the Computer' consists of nine large simulation programs and the textbook. The programs are simulating basic phenomena of wave optics. parameters of optical systems can be varied by the user. The textbook contains theoretical considerations on studied optical phenomena, recommendations concerning work with computer programs, and, especially for those wishing to deeper understand wave optics, original problems for individual solution. At the Moscow Institute of Physics and Technology the course 'Wave Optics on the Computer' is used for teaching optics in the course of general physics. The course provides both the computer assisted teaching for lectures support and computer assisted learning for students during seminars in the computer classroom.

  5. Long-term outcomes in children conceived with assisted reproductive technologies.

    2014-10-01

    Over five million children have been born worldwide through assisted reproductive technology (ART) and access to ART treatment is increasing yearly. Investigations of the health, disease, cognitive, developmental and behavioral outcomes in the children conceived with ART are often confounded by parental and other social, environmental and medical factors, including multiplicity, prematurity and low birth weight. Reports of the long-term health and psychosocial adjustment of children conceived with ART show generally good outcomes. Many of the major long-term conditions observed in the children may be associated with multiple gestations, preterm delivery and low birth weight, or with subfertility of the parents. Evidence in the male infants conceived with the aid of intracytoplasmic injection (ICSI) suggests an increased risk of reproductive tract anomalies such as hypospadias. Health-related outcomes of children born after cryopreservation of cleavage stage embryos are reassuring. Currently, our knowledge and understanding of the long-term health risks and/or benefits to the children conceived is incomplete. Measuring long-term outcomes is the first step to improving and optimizing health in the offspring conceived with medical and technological assistance. PMID:25245993

    This meta-analysis investigated the efficacy of technology-assisted interventions for individuals with social anxiety disorder (SAD). A systematic literature search in the databases Medline, PsychInfo, and Web of Science revealed 37 randomized controlled trials (2991 participants) that were grouped into internet delivered cognitive behavior therapy (ICBT; 21 trials), virtual reality exposure therapy (VRET; 3 trials), and cognitive bias modification (CBM; 13 trials). Patients undergoing ICBT and VRET showed significantly less SAD symptoms at postassessment than passive control conditions (g=0.84 and 0.82, respectively). Compared to active control conditions, ICBT had a small advantage (g=0.38) and VRET showed comparable effects (p>0.05). CBM was not more effective than passive control conditions, except when delivered in the laboratory (g=0.35). While the efficacy of CBM was limited, substantial evidence for ICBT and preliminary evidence for VRET suggests that both can effectively reduce SAD symptoms indicating the potential of technology-assisted interventions for SAD.

    The functional requirements for daily living at home are the same for a ventilator dependent quadriplegic person as they are for anyone, whether less severely disabled or able bodied. In persons with high spinal cord lesions, the necessary presence of a carer near to hand should not deter the use of assistive technology to increase independence. Maximised independence is desirable to free the carer from minute by minute tasks such as turning pages, switching lights, TV etc. This not only frees the carer for other tasks, making the caring task more bearable (and thus easier to recruit carers) but also vastly improves the morale of the disabled person. Some assistive devices, especially those concerned with mobility and transfer can avoid the need for multiple carers at times such as toiletting and going on car journeys. Whichever devices are required by the quadriplegic person, they all clearly need to be worked by a common, carefully selected input interface device matched to his or her preferences and physical abilities for switching. It is vital to ensure a technical integration of the four generic areas of device functionality: those of mobility (wheelchairs, cars), manipulation (page-turners, robotic arms), communication (keyboard emulators, voice processors, artificial speech) and control of the environment. In most countries this integration is poorly addressed owing to the different agencies involved in the provision of devices relating to each of these generic areas--despite the technology being available today.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8332373

    Assisted reproduction technology laboratories have a very high degree of complexity. Mismatches of gametes or embryos can occur, with catastrophic consequences for patients. To minimize the risk of error, a multi-institutional working group applied failure mode and effects analysis (FMEA) to each critical activity/step as a method of risk assessment. This analysis led to the identification of the potential failure modes, together with their causes and effects, using the risk priority number (RPN) scoring system. In total, 11 individual steps and 68 different potential failure modes were identified. The highest ranked failure modes, with an RPN score of 25, encompassed 17 failures and pertained to "patient mismatch" and "biological sample mismatch". The maximum reduction in risk, with RPN reduced from 25 to 5, was mostly related to the introduction of witnessing. The critical failure modes in sample processing were improved by 50% in the RPN by focusing on staff training. Three indicators of FMEA success, based on technical skill, competence and traceability, have been evaluated after FMEA implementation. Witnessing by a second human operator should be introduced in the laboratory to avoid sample mix-ups. These findings confirm that FMEA can effectively reduce errors in assisted reproduction technology laboratories. PMID:27282213

    Our aim was to fix intracapsular condylar fractures (ICF) with two resorbable long screws using preoperative computer-assisted virtual technology. From February 2008 to July 2011, 19 patients with ICF were treated with two resorbable long screws. Preoperatively we took panoramic radiographs and spiral computed tomography (CT). Depending on their digital imaging and communications in medicine (DICOM) data, the dislocated condylar segments were restored using the SimPlant Pro™ software, version 11.04. The mean (SD) widths of the condylar head and neck from lateral to medial were 19.01 (1.28)mm and 13.84 (1.13)mm, respectively. In all patients, the mandibles and the ICF seen intraoperatively corresponded with the preoperative three-dimensional and virtual reposition. All patients were followed up for 6-46 months (mean 21). Occlusion and mouth opening had been restored completely in all but one patient, and absolute anatomical reduction was also achieved in most cases. Computer-assisted virtual technology plays an important part in the diagnosis of ICF, as well as in its preoperative design. Fixation with only two resorbable long screws is an effective and reliable method for fixing ICF. PMID:22546281

    The carcasses of yellow-fat rabbits may be attractive to modern consumers, because they have a relatively high content of biologically active compounds. One of the main candidate genes associated with the yellow-fat trait is β-carotene 9',10'-oxygenase (BCO2). This study is the first report of the novel AAT-deletion mutation at codon 248 of the BCO2 gene, which has been found in homozygous yellow-fat rabbits. The deletion mutation, located at the beginning of exon 6, results in the absence of asparagine in protein. We also developed a PCR-RFLP test that supports intravital genotyping of indel polymorphism based on genomic DNA. PMID:26002694

    1998-11-01

    The US Department of Energy`s (DOE`s) nuclear facilities require characterization and documentation of the results as part of planning and decision-making for decontamination and decommissioning (D and D) projects and to release areas that have been cleaned up. Conducting radiation surveys of indoor and outdoor surfaces and generating accurate survey reports is an important component of the D and D program. The Laser Assisted Ranging and Data System (LARADS) is a characterization technology that provides real-time data on the location and concentration levels of radiological contamination. The system can be utilized with a number of available detection instruments and can be integrated with existing data analysis and mapping software technologies to generate superior quality survey data reports. This innovative technology is competitive with baseline technologies in terms of cost and survey times, but is much more flexible and provides more useful reports. The system also has the capability of electronically logging survey data, making it easy to store and retrieve. Such data are scientifically derived and not subject to interpretation. The LARADS is an extremely attractive alternative to manually generated survey data reports.

  14. A pedagogical shift from direct instruction: Technology-assisted inquiry learning (TAIL) in chemistry

    Lou, Rena Zhihong

    The purpose of this study was to develop a student-centered Technology-Assisted Inquiry Learning (TAIL) pedagogical approach and compare it with the traditional, teacher-centered, direct instruction approach in a chemistry classroom. The study investigated how the TAIL approach affected community college chemistry students' (n = 21) learning gains and perceptions during a 1.5-hour intervention when compared with the direct instruction approach. A mixed methodology was used that included both quantitative and qualitative analyses. Results led to the following three key findings for novice learners: (a) TAIL had a statistically significant effect on students' procedural application skills improvement when compared with direct instruction; (b) The magnitude of the between-group difference (Cohen's d = 1.41) indicated that TAIL had a cumulative effect on students' learning gains due to its ability to incorporate multiple components including Inquiry, Guidance, Technology, and Collaboration; (c) When combining measures of students' performance and perceived mental effort, TAIL demonstrated high-instructional efficiency with a significant difference in teaching factual knowledge and procedural applications when compared with direct instruction. In summary, the outcome of this study demonstrated both the effectiveness and efficiency of the TAIL approach as a student-centered pedagogy in teaching a basic scientific topic. This study provided a practical demonstration of the pedagogical shift in teaching science from teacher-centered direct instruction to student-centered learning by using computer software as a pedagogical agent. The results of the study contribute to the literature in the fields of guided inquiry learning pedagogy and technology-assisted science teaching.

    The escalation of Assisted Reproductive Technologies (ARTs) in India into a veritable fertility industry is the result of a multitude of reasons. This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed. As such, bodies have emerged as sale-worthy economic capital. Commercial flows of reproductive material create and deploy the division of the body into parts over which ownership is claimed, in the process following 'modern routes of capital' and raising issues of structural inequality.This paper presents a brief picture of India's fertility industry with specific focus on its ground-level operation, nature and growth. It aims to explore the industry dimensions of ARTs, by highlighting the macro picture of health care markets and medical tourism in India, the proliferation of the ART industry, market features such as the social imperative to mother, costs, promotion and marketing, unverified claims, inflated success rates, deals and offers, actors and collaborations in the field, and finally, the absence of standards.

We found few studies that focused on interactive education (3 studies) and self-monitoring (2 studies). Some recent research is emerging in dynamic tailoring (15 studies) and theoretically grounded ontologies for automated semantic processing (4 studies). Conclusions The potential capabilities and risks of active assistance technologies are not being fully explored in most current behavior change research. Designers of health behavior interventions need to consider the relevant informatics methods and algorithms more fully. There is also a need to analyze the possibilities that can result from interaction between different technology components. This requires deep interdisciplinary collaboration, for example, between health psychology, computer science, health informatics, cognitive science, and educational methodology. PMID:22698679

    Robotic-assisted surgical techniques are not yet well established among surgeon practice groups beyond a few surgical subspecialties. To help identify the facilitators and barriers to their adoption, this belief-elicitation study contextualized and supplemented constructs of the unified theory of acceptance and use of technology (UTAUT) in robotic-assisted surgery. Semi-structured individual interviews were conducted with 21 surgeons comprising two groups: users and nonusers. The main facilitators to adoption were Perceived Usefulness and Facilitating Conditions among both users and nonusers, followed by Attitude Toward Using Technology among users and Extrinsic Motivation among nonusers. The three main barriers to adoption for both users and nonusers were Perceived Ease of Use and Complexity, Perceived Usefulness, and Perceived Behavioral Control. This study's findings can assist surgeons, hospital and medical school administrators, and other policy makers on the proper adoption of robotic-assisted surgery and can guide future research on the development of theories and framing of hypotheses.

    Introduction Research to date into assisted living technologies broadly consists of 3 generations: technical design, experimental trials and qualitative studies of the patient experience. We describe a fourth-generation paradigm: studies of assisted living technologies in their organisational, social, political and policy context. Fourth-generation studies are necessarily organic and emergent; they view technology as part of a dynamic, networked and potentially unstable system. They use co-design methods to generate and stabilise local solutions, taking account of context. Methods and analysis SCALS (Studies in Co-creating Assisted Living Solutions) consists (currently) of 5 organisational case studies, each an English health or social care organisation striving to introduce technology-supported services to support independent living in people with health and/or social care needs. Treating these cases as complex systems, we seek to explore interdependencies, emergence and conflict. We employ a co-design approach informed by the principles of action research to help participating organisations establish, refine and evaluate their service. To that end, we are conducting in-depth ethnographic studies of people's experience of assisted living technologies (micro level), embedded in evolving organisational case studies that use interviews, ethnography and document analysis (meso level), and exploring the wider national and international context for assisted living technologies and policy (macro level). Data will be analysed using a sociotechnical framework developed from structuration theory. Ethics and dissemination Research ethics approval for the first 4 case studies has been granted. An important outcome will be lessons learned from individual co-design case studies. We will document the studies’ credibility and rigour, and assess the transferability of findings to other settings while also recognising unique aspects of the contexts in which they were generated

    Background. While assisted reproductive technology (ART), including in vitro fertilization has given hope to millions of couples suffering from infertility, it has also introduced countless ethical, legal, and social challenges. The objective of this paper is to identify the aspects of ART that are most relevant to present-day society and discuss the multiple ethical, legal, and social challenges inherent to this technology. Scope of Review. This paper evaluates some of the most visible and challenging topics in the field of ART and outlines the ethical, legal, and social challenges they introduce. Major Conclusions. ART has resulted in a tectonic shift in the way physicians and the general population perceive infertility and ethics. In the coming years, advancing technology is likely to exacerbate ethical, legal, and social concerns associated with ART. ART is directly challenging society to reevaluate the way in which human life, social justice and equality, and claims to genetic offspring are viewed. Furthermore, these issues will force legal systems to modify existing laws to accommodate the unique challenges created by ART. Society has a responsibility to ensure that the advances achieved through ART are implemented in a socially responsible manner. PMID:22272208

    Stronger regulations on nitrogen oxide (NOx) production have recently promoted the creation of a diverse array of technologies for NOx reduction, particularly within the combustion process, where reduction is least expensive. In this paper, we discuss a new combustion technology that can reduce NOx emissions within industrial burners to single-digit parts per million levels without employing exhaust gas recirculation or other NOx reduction mechanisms. This new technology uses a simple modification of commercial burners, such that they are able to perform plasma-assisted staged combustion without altering the outer configuration of the commercial reference burner. We embedded the first-stage combustor within the head of the commercial reference burner, where it operated as a reformer that could host a partial oxidation process, producing hydrogen-rich reformate or synthesis gas product. The resulting hydrogen-rich flow then ignited and stabilized the combustion flame apart from the burner rim. Ultimately, the enhanced mixing and removal of hot spots with a widened flame area acted as the main mechanisms of NOx reduction. Because this plasma burner acted as a low NOx burner and was able to reduce NOx by more than half compared to the commercial reference burner, this methodology offers important cost-effective possibilities for NOx reduction in industrial applications.

    Spinal cord injury often impacts a person’s ability to perform critical activities of daily living and can have a negative impact on their quality of life. Assistive technology aims to bridge this gap to augment function and increase independence. It is critical to involve consumers in the design and evaluation process as new technologies, like brain-computer interfaces (BCIs), are developed. In a survey study of fifty-seven veterans with spinal cord injury who were participating in the National Veterans Wheelchair Games, we found that restoration of bladder/bowel control, walking, and arm/hand function (tetraplegia only) were all high priorities for improving quality of life. Many of the participants had not used or heard of some currently available technologies designed to improve function or the ability to interact with their environment. The majority of individuals in this study were interested in using a BCI, particularly for controlling functional electrical stimulation to restore lost function. Independent operation was considered to be the most important design criteria. Interestingly, many participants reported that they would be willing to consider surgery to implant a BCI even though non-invasiveness was a high priority design requirement. This survey demonstrates the interest of individuals with spinal cord injury in receiving and contributing to the design of BCI. PMID:23760996

    2013-01-01

    Background With an ever-growing ageing population, dementia is fast becoming the chronic disease of the 21st century. Elderly people affected with dementia progressively lose their autonomy as they encounter problems in their Activities of Daily Living (ADLs). Hence, they need supervision and assistance from their family members or professional caregivers, which can often lead to underestimated psychological and financial stress for all parties. The use of Ambient Assistive Living (AAL) technologies aims to empower people with dementia and relieve the burden of their caregivers. The aim of this paper is to present the approach we have adopted to develop and deploy a system for ambient assistive living in an operating nursing home, and evaluate its performance and usability in real conditions. Based on this approach, we emphasise on the importance of deployments in real world settings as opposed to prototype testing in laboratories. Methods We chose to conduct this work in close partnership with end-users (dementia patients) and specialists in dementia care (professional caregivers). Our trial was conducted during a period of 14 months within three rooms in a nursing home in Singapore, and with the participation of eight dementia patients and two caregivers. A technical ambient assistive living solution, consisting of a set of sensors and devices controlled by a software platform, was deployed in the collaborating nursing home. The trial was preceded by a pre-deployment period to organise several observation sessions with dementia patients and focus group discussions with professional caregivers. A process of ground truth and system’s log data gathering was also planned prior to the trial and a system performance evaluation was realised during the deployment period with the help of caregivers. An ethical approval was obtained prior to real life deployment of our solution. Results Patients’ observations and discussions allowed us to gather a set of requirements

  6. Obtrusiveness of information-based assistive technologies as perceived by older adults in residential care facilities: a secondary analysis.

    With the anticipated growth in the older adult population in the next few years, information designers are examining new ways for assistive technologies to support independent living and quality of life for adults as they age. Central to the role of assistive technology to support and enhance quality of life is the development of non-obtrusive technologies. Despite the importance of non-obtrusiveness to the design of assistive technologies, there remains no standard definition of obtrusiveness or measurement instrument. A conceptual framework for obtrusiveness in home telehealth technologies has recently been proposed but has not yet been tested empirically. This project performed a secondary analysis of focus group and interview data to explore the presence of the dimensions of the obtrusiveness framework in older adults' responses to information-based assistive technologies in residential care facilities. We found the existing data contained examples of each dimension (physical, usability, privacy, function, human interaction, self-concept, routine, and sustainability) and 16 of the 22 subcategories proposed by the obtrusiveness framework. These results provide general support for the framework, although further prospective validation research is needed. Potential enhancements to the framework are proposed. PMID:17701829

    In France as in other countries, more and more single women and lesbian couples wish to become mothers. To carry through their parenting project they may consult a physician in France and often go abroad in order to get Assisted Reproductive Technologies with donor sperm (ARTD). Should ARTD be available to those women in France? The physician has not to take the decision. In such situations ARTD has no medical indication or contraindication. This assisted procreation raises many questions on children development and well-being. The results of studies made in other countries are often reassuring but their methodologies do not allow any conclusion to be drawn and grey areas persist. Therefore it should be necessary to develop a research effort in the field as it recently started in France. Would ARTD access to women without a male partner be legalized, the law should respect the ethical principles of non-payment and anonymity associated with donation of all body components. In any case, it should also allow an efficient medical care to be performed to ensure under the best conditions the well-being of the children and their mothers. PMID:26753417

    Creation of both gametes, sperm and oocyte, and their fusion during fertilization are essential step for beginning of life. Although molecular mechanisms regulating gametogenesis, fertilization, and early embryonic development are still subjected to intensive study, a lot of phenomena remain unclear. Based on our best knowledge and own results, we consider gasotransmitters to be essential for various signalisation in oocytes and embryos. In accordance with nitric oxide (NO) and hydrogen sulfide (H2S) physiological necessity, their involvement during oocyte maturation and regulative role in fertilization followed by embryonic development have been described. During these processes, NO- and H2S-derived posttranslational modifications represent the main mode of their regulative effect. While NO represent the most understood gasotransmitter and H2S is still intensively studied gasotransmitter, appreciation of carbon monoxide (CO) role in reproduction is still missing. Overall understanding of gasotransmitters including their interaction is promising for reproductive medicine and assisted reproductive technologies (ART), because these approaches contend with failure of in vitro assisted reproduction.

    The advent of innovative techniques for addressing infertility has made for exciting times in the arena of andrology. The success of microTESE for retrieving sperm has enabled azoospermic men to have the opportunity to father biological children when it was previously impossible. The ability to offer a variety of assisted reproductive techniques that includes intracytoplasmic sperm injection has opened the door for couples with male factor infertility who were otherwise untreatable. With the multitude of options available to infertile couples, however, comes an unsurprising degree of controversy regarding what treatments should be offered and when. Complicating the picture is the question of if and when varicocele repair should be undertaken, and the financial implications of the treatment decisions that are made. The infertile couple with varicocele warrants careful consideration. The overall efficacy of varicocele repair as well as cost-effectiveness of repair compared to immediate microTESE in azoospermic men and assisted reproductive technology in men with suboptimal semen parameters will be reviewed.

    Although in the UK the upper age limit for National Health Service (NHS) provision of in vitro fertilisation (IVF) is 39 years of age there has been an increase in number of women having fertility treatment in their 40s. However, the success rates of IVF and intra-uterine insemination (IUI) in this group remain low. Human Fertilisation and Embryology Authority (HFEA) data from 2006 showed that the live-birth rate from IVF in the UK was 11% in the age group 40-42, 4.6% in the age group 43-44 and less than 4% in women over 44. We performed a literature search for studies using terms and combinations of terms in online databases and published meta-analyses reporting the outcome of interventions in older women. This review showed that assisted reproduction technologies (ARTs) continue to have low live-birth rates in women over 40. Trials showed that assisted hatching may increase the chance of pregnancy in women with poor history. Blastocyst transfer is associated with better outcome, whereas application of pre-implantation genetic screening (PGS) in older women has not increased the success rates. It appears that, with the exception of egg-donation, ART has no answer yet to age-related decline of female fertility. PMID:21329469

    The N-end rule relates the in vivo half-life of a protein to the identity of its N-terminal residue. Distinct versions of the N-end rule operate in bacteria, fungi, and mammals. We report the cloning and analysis of aat, the Escherichia coli gene that encodes leucyl, phenylalanyl-tRNA-protein transferase (L/F-transferase), a component of the bacterial N-end rule pathway. L/F-transferase is required for the degradation of N-end rule substrates bearing an N-terminal arginine or lysine. The aat gene maps to the 19-min region of the E. coli chromosome and encodes a 234-residue protein whose sequence lacks significant similarities to sequences in data bases. In vitro, L/F-transferase catalyzes the posttranslational conjugation of leucine or phenylalanine to the N termini of proteins that bear an N-terminal arginine or lysine. However, the isolation and sequence analysis of a beta-galactosidase variant engineered to expose an N-terminal arginine in vivo revealed the conjugation of leucine but not of phenylalanine to the N terminus of the beta-galactosidase variant. Thus, the specificity of L/F-transferase in vivo may be greater than that in vitro. The aat gene is located approximately 1 kb from clpA, which encodes a subunit of ATP-dependent protease Clp. Although both aat and clpA are required for the degradation of certain N-end rule substrates, their nearly adjacent genes are convergently transcribed. The aat gene lies downstream of an open reading frame that encodes a homolog of the mammalian multidrug resistance P glycoproteins. PMID:8331068

    This article reports the use of an expert panel to perform content validation of an experimental assessment process for the safety of assistive technology (AT) adopted by farmers with disabilities. The validation process was conducted by a panel of six experts experienced in the subject matter, i.e., design, use, and assessment of AT for farmers with disabilities. The exercise included an evaluation session and two focus group sessions. The evaluation session consisted of using the assessment process under consideration by the panel to evaluate a set of nine ATs fabricated by a farmer on his farm site. The expert panel also participated in the focus group sessions conducted immediately before and after the evaluation session. The resulting data were analyzed using discursive analysis, and the results were incorporated into the final assessment process. The method and the results are presented with recommendations for the use of expert panels in research projects and validation of assessment tools. PMID:21919319

    As a number of children born by assisted reproductive technology (ART) are increasing each year across the developed world, the health of such offspring is a matter of public concern. Does the integrity of the paternal genome impact on offspring health? In societal terms, as birth rates fall, and the Western population become unsustainable, do the benefits outweigh the costs of creating and providing for this ART conceived subpopulation? There are little data to date to answer these questions. The long-term health of such children has largely been ignored, and success measured only by early (prebirth) outcomes such as embryo quality or pregnancy. However, there are powerful paradigms such as ageing and smoking that give vital clues as to the potential impact of unhealthy spermatozoa on disease risk, mental and physical health, fertility and mortality of these offspring.

    An undesired side effect of cancer treatment is potential subfertility or infertility. Timely cryopreservation of semen is the best modality to ensure fertility. This retrospective data analysis established the usage rate of cryopreserved semen from cancer patients. Pubertal and post-pubertal patients who could become infertile as a result of cancer (treatment) were offered the option to cryopreserve semen prior to treatment. Of the 898 patients who cryopreserved their semen in our hospital, 96 (10.7%) used this for assisted reproductive technology. The live birth rates for intrauterine insemination, in-vitro fertilization, intracytoplasmic sperm injection and cryopreserved embryo transfer were 13%, 29%, 32% and 17%, respectively. Of all couples involved, 77% achieved parenthood, i.e. 60 of the 78 patients (with complete follow-up) fathered at least one child. PMID:26687904

Effects of liquefaction conditions such as liquefaction time, catalyst percentage, solvent/BSS mass ratio, PEG/EG volume ratio on liquefaction were investigated experimentally. The results showed that the introduction of LPMPT significantly shortened the liquefaction time to 3min without extra heating. The liquefaction yield reached 96.73% under the optimal conditions. The formation of massive reactive species and instantaneous heat accumulation both contributed to the rapid liquefaction of BSS. Thus, LPMPT could be considered as a simple and efficient method for the assistance of biomass fast liquefaction. PMID:27426102

    Drs. Meldrum and de Ziegler contrast medicine with the ultra-safe industry of aviation. Analogous to the "right patient, right side, and right organ" procedures already instituted widely throughout medicine, they emphasize the extreme importance and methods for identification and tracking of specimens and recipients for assisted reproductive technology (ART) procedures. One of the authors describes his experience with a formal "ISO" accreditation process that standardizes most aspects of risk and safety management. Because risk and safety management has yet to be commonly extended into physicians' offices and that is where ART procedures are usually recommended and carried out, detailed suggestions are offered regarding ways to reduce risk and maximize safety in that environment. Finally, a suggestion is made for establishment of a Clinical Safety Board for ART so adverse events are reported and investigated, promoting educative efforts and preventive strategies to enhance future patient safety.

    Children conceived via assisted reproductive technologies (ART) are nowadays a substantial proportion of the population. It is important to follow up these children and evaluate whether they have elevated health risks compared to naturally conceived (NC) children. In recent years there has been a lot of work in this field. This review will summarize what is known about the health of ART-conceived children, encompassing neonatal outcomes, birth defects, growth and gonadal developments, physical health, neurological and neurodevelopmental outcomes, psychosocial developments, risk for cancer, and epigenetic abnormalities. Most of the children conceived after ART are normal. However, there is increasing evidence that ART-conceived children are at higher risk of poor perinatal outcome, birth defects, and epigenetic disorders, and the mechanism(s) leading to these changes have not been elucidated. Continuous follow-up of children after ART is of great importance as they progress through adolescence into adulthood, and new ART techniques are constantly being introduced. PMID:23645173

  1. The Potential Applications of Peroxisome Proliferator-Activated Receptor δ Ligands in Assisted Reproductive Technology

    2008-01-01

    Peroxisome proliferator-activated receptor δ (PPARδ, also known as PPARβ) has ubiquitous distribution and extensive biological functions. The reproductive function of PPARδ was first revealed in the uterus at the implantation site. Since then, PPARδ and its ligand have been discovered in all reproductive tissues, including the gametes and the preimplantation embryos. PPARδ in preimplantation embryos is normally activated by oviduct-derived PPARδ ligand. PPARδ activation is associated with an increase in embryonic cell proliferation and a decrease in programmed cell death (apoptosis). On the other hand, the role of PPARδ and its ligand in gamete formation and function is less well understood. This review will summarize the reproductive functions of PPARδ and project its potential applications in assisted reproductive technology. PMID:19096716

    Ambient assisted living (AAL) technologies can provide assistance and support to persons with dementia. They might allow them the possibility of living at home for longer whilst maintaining their comfort and security as well as offering a way towards reducing the huge economic and personal costs forecast as the incidence of dementia increases worldwide over coming decades. However, the development, introduction and use of AAL technologies also trigger serious ethical issues. This paper is a systematic literature review of the on-going scholarly debate about these issues. More specifically, we look at the ethical issues involved in research and development, clinical experimentation, and clinical application of AAL technologies for people with dementia and related stakeholders. In the discussion we focus on: (1) the value of the goals of AAL technologies, (2) the special vulnerability of persons with dementia in their private homes, (3) the complex question of informed consent for the usage of AAL technologies.

    Background Assisted Reproductive Technology (ART) reports generated by the Centers for Disease Control and Prevention (CDC) exclude embryo banking cycles from outcome calculations. Methods We examined data reported to the CDC in 2013 for the impact of embryo banking exclusion on national ART outcomes by recalculating autologous oocyte ART live birth rates. Inflation of reported fresh ART cycle live birth rates was assessed for all age groups of infertile women as the difference between fresh cycle live births with reference to number of initiated fresh cycles (excluding embryo banking cycles), as typically reported by the CDC, and fresh cycle live births with reference to total initiated fresh ART cycles (including embryo banking cycles). Results During 2013, out of 121,351 fresh non-donor ART cycles 27,564 (22.7%) involved embryo banking. The proportion of banking cycles increased with female age from 15.5% in women <35 years to 56.5% in women >44 years. Concomitantly, the proportion of thawed cycles decreased with advancing female age (P <0.0001). Exclusion of embryo banking cycles led to inflation of live birth rates in fresh ART cycles, increasing in size in parallel to advancing female age and utilization of embryo banking, reaching 56.3% in women age >44. The inflation of live birth rates in thawed cycles could not be calculated from the publically available CDC data but appears to be even greater. Conclusions Utilization of embryo banking increased during 2013 with advancing female age, suggesting a potential age selection bias. Exclusion of embryo banking cycles from national ART outcome reports significantly inflated national ART success rates, especially among older women. Précis Exclusion of embryo banking cycles from US National Assisted Reproductive Technology outcome reports significantly inflates reported success rates especially in older women. PMID:27159215

    Many countries have a rapidly ageing population, placing strain on health services and creating a growing market for assistive technology for older people. We have, through a student-led, 12-week project for 10 students from a variety of science and engineering backgrounds, developed an integrated sensor system to enable older people, or those at risk, to live independently in their own homes for longer, while providing reassurance for their family and carers. We provide details on the design procedure and performance of our sensor system and the management and execution of a short-term, student-led research project. Detailed information on the design and use of our devices, including a door sensor, power monitor, fall detector, general in-house sensor unit and easy-to-use location-aware communications device, is given, with our open designs being contrasted with closed proprietary systems. A case study is presented for the use of our devices in a real-world context, along with a comparison with commercially available systems. We discuss how the system could lead to improvements in the quality of life of older users and increase the effectiveness of their associated care network. We reflect on how recent developments in open source technology and rapid prototyping increase the scope and potential for the development of powerful sensor systems and, finally, conclude with a student perspective on this team effort and highlight learning outcomes, arguing that open technologies will revolutionize the way in which technology will be deployed in academic research in the future.

    The number of older Americans afflicted by Alzheimer disease and related dementias will triple to 13 million persons by 2050, thus greatly increasing healthcare needs. An approach to this emerging crisis is the development and deployment of intelligent assistive technologies that compensate for the specific physical and cognitive deficits of older adults with dementia, and thereby also reduce caregiver burden. The authors conducted an extensive search of the computer science, engineering, and medical databases to review intelligent cognitive devices, physiologic and environmental sensors, and advanced integrated sensor networks that may find future applications in dementia care. Review of the extant literature reveals an overwhelming focus on the physical disability of younger persons with typically nonprogressive anoxic and traumatic brain injuries, with few clinical studies specifically involving persons with dementia. A discussion of the specific capabilities, strengths, and limitations of each technology is followed by an overview of research methodological challenges that must be addressed to achieve measurable progress to meet the healthcare needs of an aging America.

    Rehabilitation service providers in rural or underserved areas are often challenged in meeting the needs of their complex patients due to limited resources in their geographical area. Recruitment and retention of the rural clinical workforce are beset by the ongoing problems associated with limited continuing education opportunities, professional isolation, and the challenges inherent in coordinating rural community healthcare. People with disabilities who live in rural communities also face challenges accessing healthcare. Traveling long distances to a specialty clinic for necessary expertise may be troublesome due to inadequate or unavailable transportation, disability specific limitations, and financial limitations. Distance and lack of access are just two threats to quality of care that now being addressed by the use of videoconferencing, information exchange, and other telecommunication technologies that facilitate telerehabilitation. This white paper illustrates and summarizes clinical and vocational applications of telerehabilitation. We provide definitions related to the fields of telemedicine, telehealth, and telerehabilitation, and consider the impetus for telerehabilitation. We review the telerehabilitation literature for assistive technology applications; pressure ulcer prevention; virtual reality applications; speech-language pathology applications; seating and wheeled mobility applications; vocational rehabilitation applications; and cost-effectiveness. We then discuss external telerehabilitation influencers, such as the positions of professional organizations. Finally, we summarize clinical and policy issues in a limited context appropriate to the scope of this paper. PMID:25945163

    2003-09-01

    Hearing-impaired people, and particularly hearing-aid and cochlear-implant users, often have difficulty communicating over the telephone. The intelligibility of telephone speech is considerably lower than the intelligibility of face-to-face speech. This is partly because of lack of visual cues, limited telephone bandwidth, and background noise. In addition, cellphones may cause interference with the hearing aid or cochlear implant. To address these problems that hearing-impaired people experience with telephones, this paper proposes a wireless phone adapter that can be used to route the audio signal directly to the hearing aid or cochlear implant processor. This adapter is based on Bluetooth technology. The favorable features of this new wireless technology make the adapter superior to traditional assistive listening devices. A hardware prototype was built and software programs were written to implement the headset profile in the Bluetooth specification. Three cochlear implant users were tested with the proposed phone-adapter and reported good speech quality. PMID:14518792

    The ‘E-servant’, a programmable system to control and manage assistive technologies, telehealth and telecare devices in a home environment is presented. The E-servant is programmed using a simple graphical interface that allows the user to build a dialogue in the form of a production rule system, which is triggered by a patient- or technology-initiated event. The patient interacts with the system through a personalised user interface to reach their goal of completing a task. These tasks, which the authors call ‘scenarios’, can be designed for users of different abilities (cognitive and/or physical). They can also be given priority levels, for example if a potential emergency situation arises in the patient's home, a scenario associated with the sensing of this event takes highest priority. The research presented in this Letter outlines the E-servant, its programming tool and reports its evaluation in living laboratory settings. The results suggest that it can be used as a central management system for supporting an integrated support environment for facilitating healthcare and activities of daily living, especially for older patients.

    2014-01-01

    Assistive listening devices (ALDs) refer to various types of amplification equipment designed to improve the communication of individuals with hard of hearing to enhance the accessibility to speech signal when individual hearing instruments are not sufficient. There are many types of ALDs to overcome a triangle of speech to noise ratio (SNR) problems, noise, distance, and reverberation. ALDs vary in their internal electronic mechanisms ranging from simple hard-wire microphone-amplifier units to more sophisticated broadcasting systems. They usually use microphones to capture an audio source and broadcast it wirelessly over a frequency modulation (FM), infra-red, induction loop, or other transmission techniques. The seven types of ALDs are introduced including hardwire devices, FM sound system, infra-red sound system, induction loop system, telephone listening devices, television, and alert/alarm system. Further development of digital wireless technology in hearing instruments will make possible direct communication with ALDs without any accessories in the near future. There are two technology solutions for digital wireless hearing instruments improving SNR and convenience. One is near-field magnetic induction combined with Bluetooth radio frequency (RF) transmission or proprietary RF transmission and the other is proprietary RF transmission alone. Recently launched digital wireless hearing aid applying this new technology can communicate from the hearing instrument to personal computer, phones, Wi-Fi, alert systems, and ALDs via iPhone, iPad, and iPod. However, it comes with its own iOS application offering a range of features but there is no option for Android users as of this moment. PMID:25566400

Two groups of expert and novice clinicians (total, n = 26) took part in this study. Each group filled out system usability scale (SUS) to evaluate OSCAR's usability. The novice group completed a learning questionnaire to assess OSCAR's effect on their ability to learn the matching process. Both groups rated OSCAR's usability as "very good", (M [SUS] = 80.7, SD = 11.6, median = 83.7) by the novices, and (M [SUS] = 81.2, SD = 6.8, median = 81.2) by the experts. The Mann-Whitney results indicated that no significant differences were found between the expert and novice groups in terms of OSCAR's usability. A significant positive correlation existed between the usability of OSCAR and the ability to learn the adaptation process (rs = 0.46, p = 0.04). Usability is an important factor in the acceptance of a system. The successful application of user-centered design principles during the development of OSCAR may serve as a case study that models the significant elements to be considered, theoretically and practically in developing other systems. Implications for Rehabilitation Creating a CDSS with a focus on its usability is an important factor for its acceptance by its users. Successful usability outcomes can impact the learning process of the subject matter in general, and the AT prescription process in particular. The successful application of User-Centered Design principles during the development of OSCAR may serve as a case study that models the significant elements to be considered, theoretically and practically. The study emphasizes the importance of close collaboration between the developers and

    In complex (robot-assisted) laparoscopic radioguided surgery procedures, or when low activity lesions are located nearby a high activity background, the limited maneuverability of a laparoscopic gamma probe (LGP; 4 degrees of freedom (DOF)) may hinder lesion identification. We investigated a drop-in gamma probe (DIGP) technology to be inserted via a trocar, after which the laparoscopic surgical tool at hand can pick it up and maneuver it. Phantom experiments showed that distinguishing a low objective from a high background source (1:100 ratio) was only possible with the detector faced >90° from the high background source. Signal-low-objective-to-background ratios of 3.77, 2.01 and 1.84 were found for detector angles of 90°, 135° and 180°, respectively, whereas detector angles of 0° and 45° were unable to distinguish the sources. This underlines the critical role probe positioning plays. We then focused on engineering of the gripping part for optimal DIGP pick-up with a conventional laparoscopic forceps (4 DOF) or a robotic forceps (6 DOF). DIGPs with 0°, 45°, 90°, and 135° -grip orientations were designed, and their maneuverability- and scanning direction were evaluated and compared to a conventional LGP. The maneuverability- and scanning direction of the DIGP was found highest when using the robotic forceps, with the largest effective scanning direction range obtained with the 90° -grip design (0-180° versus 0-111°, 0-140°, and 37-180° for 0°, 45° and 135° -grip designs, respectively). For the laparoscopic forceps, the scan direction directly translated from the angle of the grip design with the advantage that the 135° -gripped DIGP could be faced backwards (not possible with the conventional LGP). In the ex vivo clinical setup, the surgeon rated DIGP pick-up most convenient for the 45°-grip design. Concluding, the DIGP technology was successfully introduced. Optimization of the grip design and grasping angle of the DIGP increased its utility

    This invited presentation is intended to cover clinical developments in the evolution of assisted reproductive technology (ART), a process which was attempted during the 1940's and 50's and culminated in the first fruition in 1978. The first in vitro fertilisation (IVF) child ensued following the partnership by a scientist with a focussed ambition (Nobel laureate Robert Edwards) joining with the gynaecologist who introduced laparoscopy to Britain in the late 60's (Patrick Steptoe). My journey commenced in 1976 as a clinician who became immersed in the embryological and endocrinological science, whence most progress in ART emanates, and continued into a medical directorship position from which this personal view is documented. Several clinical advances have been important developments in the understanding and management of sub-fertile patients. However evolution of the various laboratory sciences has been the major key essential to meeting both the immediate as well as the long-term needs for human reproduction. The future requires a much better understanding and control over gametogenesis and a laboratory process which much more closely duplicates intrinsic reproductive physiology, avoiding gamete and embryo exposure to the atmosphere.This invited presentation is intended to cover clinical developments in the evolution of assisted reproductive technology (ART), a process which was attempted during the 1940's and 50's and culminated in the first fruition in 1978.

    2010-01-01

    We constructed a transposon (transposon assisted gene insertion technology, or TAGIT) that allows the random insertion of gfp (or other genes) into chromosomal loci without disrupting operon structure or regulation. TAGIT is a modified Tn5 transposon that uses Kan(R) to select for insertions on the chromosome or plasmid, beta-galactosidase to identify in-frame gene fusions, and Cre recombinase to excise the kan and lacZ genes in vivo. The resulting gfp insertions maintain target gene reading frame (to the 5' and 3' of gfp) and are integrated at the native chromosomal locus, thereby maintaining native expression signals. Libraries can be screened to identify GFP insertions that maintain target protein function at native expression levels, allowing more trustworthy localization studies. We here use TAGIT to generate a library of GFP insertions in the Escherichia coli lactose repressor (LacI). We identified fully functional GFP insertions and partially functional insertions that bind DNA but fail to repress the lacZ operon. Several of these latter GFP insertions localize to lacO arrays integrated in the E. coli chromosome without producing the elongated cells frequently observed when functional LacI-GFP fusions are used in chromosome tagging experiments. TAGIT thereby faciliates the isolation of fully functional insertions of fluorescent proteins into target proteins expressed from the native chromosomal locus as well as potentially useful partially functional proteins.

    A survey was designed and administered in this study to assess the use of assistive technology for cognition (ATC), especially portable electronic ATC, among veterans with traumatic brain injury (TBI). The aim of the survey was to obtain information on current ATC devices and applications use, users' experience with different features of ATC, and relevant training/support for their ATC. Twenty-nine veterans with TBI participated in this study. Results showed that portable electronic ATC, especially smartphones and a variety of apps, were widely used by the participants to compensate for cognitive limitations. Portable electronic devices such as smartphones and smart pads received higher usability ratings than paper-based tools. More than 75% of participants did not go through a service delivery process for these electronic ATC. The information collected in the study provided a more updated picture of ATC use, especially portable electronic ATC use, among people with TBI. It also potentially informs the future development of ATC and supports the need for training and an appropriate acquisition process of portable electronic ATC devices. PMID:27244066

    The use of Assisted Reproductive Technologies (ARTs) in modern cattle breeding is an important tool for improving the production of dairy and beef cattle. A frequently employed ART in the cattle industry is in vitro production of embryos. However, bovine in vitro produced embryos differ greatly from their in vivo produced counterparts in many facets, including developmental competence. The lower developmental capacity of these embryos could be due to the stress to which the gametes and/or embryos are exposed during in vitro embryo production, specifically ovarian hormonal stimulation, follicular aspiration, oocyte in vitro maturation in hormone supplemented medium, sperm handling, gamete cryopreservation, and culture of embryos. The negative effects of some ARTs on embryo development could, at least partially, be explained by disruption of the physiological epigenetic profile of the gametes and/or embryos. Here, we review the current literature with regard to the putative link between ARTs used in bovine reproduction and epigenetic disorders and changes in the expression profile of embryonic genes. Information on the relationship between reproductive biotechnologies and epigenetic disorders and aberrant gene expression in bovine embryos is limited and novel approaches are needed to explore ways in which ARTs can be improved to avoid epigenetic disorders.

    Gonadotropins extracted from the urine of post-menopausal women have traditionally been used to stimulate folliculogenesis in the treatment of infertility and in assisted reproductive technology (ART). Products, such as human menopausal gonadotropin (hMG), consist not only of a mixture of the hormones, follicle-stimulating hormone (FSH), luteinising hormone (LH) and human chorionic gonadotropin (hCG), but also other biologically active contaminants, such as growth factors, binding proteins and prion proteins. The actual amount of molecular LH in hMG preparations varies considerably due to the purification process, thus hCG, mimicking LH action, is added to standardise the product. However, unlike LH, hCG plays a different role during the natural human menstrual cycle. It is secreted by the embryo and placenta, and its main role is to support implantation and pregnancy. More recently, recombinant gonadotropins (r-hFSH and r-hLH) have become available for ART therapies. Recombinant LH contains only LH molecules. In the field of reproduction there has been controversy in recent years over whether r-hLH or hCG should be used for ART. This review examines the existing evidence for molecular and functional differences between LH and hCG and assesses the clinical implications of hCG-supplemented urinary therapy compared with recombinant therapies used for ART.

    Female infertility rates have increased by approximately 4% since the 1980s. There is evidence of adverse effects on female fertility in relation to exposure of chemical pollution in recent years. Follicular fluid samples were collected from 127 woman patients (aged 20-35) who underwent assisted reproductive technologies (ART) and had no records indicating occupational exposure to OCPs. Seventeen OCPs were analyzed in this study. The results showed that methoxychlor was dominant, accounted for 13.4% of total OCPs with a mean concentration of 167.9 ± 33.9 ng/g lipid weight (lw), followed by heptachlor-epoxide, hexachlorocyclohexanes, endrin and DDT. The concentrations of OCPs in the follicular fluid samples in the present study were moderate in comparison with those reported from developed or industrialized countries. All these pollutants can accumulate in different tissues of human body through diet, drinking water and respiration. No correlation between patient age and OCP concentrations was observed in this study. PMID:26412266

    Background The field of infertility medicine has witnessed a surge of scientific developments in recent years, but research on public attitudes towards infertility treatments has remained minimal. This study examined the social and demographic factors that affect women’s attitudes towards assisted reproductive technology (ART) in general, as well as their opinions of specific issues related to ART. Materials and Methods This cross-sectional study was conducted from March 2011 to April 2011 by means of an online survey administered to a sample of 287 women. Results Women with a longer length of awareness of ART had significantly greater attitudinal favorability towards ART. Political affiliation was also significantly related to general attitudes, as well as several specific aspects of ART issues. Conclusion The results of this study suggest that several factors influence attitudes that women hold in regards to ART. Identifying some of these factors serves as a crucial starting point for devising strategies to increase public acceptance of ART. PMID:27110326

    Objective: To investigate the relationship between male’s body mass index (BMI) and the outcome of assisted reproductive technology (ART). In this retrospective study, we analyzed the data from 729 cycles of female patients aged 38 years or less, with normal BMI and who received IVF treatments between January, 2013 and June, 2014. The patients were divided into normal weight (n = 358), overweight (n = 267), and obese (n = 104) groups according to the BMI of their male partners. Embryonic development and pregnancy outcomes in these three groups were compared. Results: With increasing BMI, fertilization rates decreased proportionately (P < 0.05); but embryonic cleavage rates and effective embryo rates were not significantly affected (P > 0.05). There was no significant difference in implantation rates, pregnancy rates, or early miscarriage rates (P > 0.05) among the three groups. Conclusions: High male BMI affects fertilization rate with ART; and we recommend that men of reproductive age adjust their lifestyles accordingly and make efforts to control their weight.

    The efficiency of assisted reproductive technologies (ARTs) in nonhuman primates is low due to no screening criterions for selecting sperm, oocyte, and embryo as well as its surrogate mothers. Here we analyzed 15 pairs of pregnant and non-pregnant cynomolgus monkeys, each pair of which received embryos from one batch of fertilized oocytes, and found ratio of endometrial to myometrial thicknesses in abdominal ultrasonic transverse section of uterus is a reliable indicator for selection of recipients for embryo transfer. We performed 305 ovarian stimulations in 128 female cynomolgus monkeys and found that ovarian stimulation can be performed in a whole year and repeated up to six times in the same monkey without deteriorating fertilization potential of eggs until a poor response to stimulation happened. Fertilization can be efficiently achieved with both conventional and piezo-driven intracytoplasmic sperm injection procedures. In semen collection, semen quality is higher with the penile robe electrical stimulus method compared with the rectal probe method. Moreover, caesarean section is an effective strategy for increasing baby survival rates of multiple pregnancies. These findings provide a practical guidance for the efficient use of ARTs, facilitating their use in genetic engineering of macaque monkeys for basic and translational neuroscience research.

    PURPOSE. The purpose of this study was to determine how well graduates of a rehabilitation counselling master programme were prepared to work with clients in assistive technology (AT) device selection or referral of resources. Specifically, inquiry was conducted as to how graduates have incorporated AT into their professional practice, their level of comfort with exploring AT solutions, and whether they felt additional training was needed. METHODS. The methodology used was an online survey of multiple choice and text boxes sent to rehabilitation counselling graduates. Descriptive statistics and cross tabulations were used to provide the range of responses. Trends were analysed to highlight differences between various factors. RESULTS. Responses indicated that graduates did find the dedicated AT course helpful in learning about the AT process. However, a number of respondents were not comfortable in participating in the AT process and were not incorporating the AT process into their work. CONCLUSIONS. Future studies should explore the role of AT acquisition from the perspective of rehabilitation counsellors and also examine why graduates are not incorporating the AT process. Respondents indicated the need for continuing education and professional development in this area. PMID:21561317

    Certain restrictions on public funding for assisted reproductive technology (ART) are articulated and defended by recourse to a distinction between medical infertility and social infertility. We propose that underlying the prioritization of medical infertility is a vision of medicine whose proper role is to restore but not to improve upon nature. We go on to mark moral responses that speak of investments many continue to make in nature as properly an object of reverence and gratitude and therein (sometimes) a source of moral guidance. We draw on the work of Ludwig Wittgenstein in arguing for the plausibility of an appeal to nature in opposition to the charge that it must contain a logical fallacy. We also invite consideration of the moral plausibility of some appeal to nature. Finally, we examine what follows in the case of ART. Should medicine respect as natural limits that should not be overcome: the need for a man and a woman in reproduction; menopause; and even declining fertility with age? We must first ask ourselves to what degree we should defer to nature in the conduct of medicine, at least in the particular if not the general case. This will involve also asking ourselves what we think is natural and in what instances and spirit might we defy nature. Divergent opinions and policies concerning who should receive ART treatment and public funding are more easily understood in view of the centrality, complexity and fundamental nature of these questions.

    Tongue Drive System (TDS) is a wireless and wearable assistive technology (AT) that enables people with severe disabilities to control their computers, wheelchairs, and electronic gadgets using their tongue motion. We developed the TDS to control smartphone's (iPhone/iPod Touch) built-in and downloadable apps with a customized Bluetooth mouse module by emulating finger taps on the touchscreen. The TDS-iPhone Bluetooth mouse interface was evaluated by four able-bodied subjects to complete a scenario consisting of seven tasks, which were randomly ordered by using touch on the iPhone screen with index finger, a computer mouse on iPhone, and TDS-iPhone Bluetooth mouse interface with tongue motion. Preliminary results show that the average completion times of a scenario with touch, mouse, and TDS are 165.6 ± 14.50 s, 186.1 ± 15.37 s, and 651.6 ± 113.4 s, respectively, showing that the TDS is 84.37% and 81.16% slower than touch and mouse for speed of typing with negligible errors. Overall, considering the limited number of commands and unfamiliarity of the subjects with the TDS, we achieved acceptable results for hands-free functionality. PMID:23366818

    Intake of full-fat dairy has been linked to lower semen quality but whether this leads to decreased fertility is unknown. To address this question, we prospectively evaluated the association of men's dairy intake with treatment outcomes of subfertile couples undergoing assisted reproductive technology (ART). We followed 142 men from couples undergoing infertility treatment with ART at an academic fertility centre between 2007 and 2014. Couples completed dietary assessments prior to treatment, and the female partners underwent a total of 248 ART cycles. Multivariable generalized linear mixed models were used to examine the association of dairy intake with fertilization, implantation, clinical pregnancy and live birth rates adjusting for age, body mass index, smoking status, total exercise time, dietary patterns, alcohol, caffeine, total energy intake, and female dairy intake. Intake of dairy foods, regardless of their fat content, was not associated with fertilization, implantation, clinical pregnancy or live birth rates. The adjusted live birth rates (95% confidence interval) for couples in increasing quartiles of men's dairy intake were 0.42 (0.25, 0.60), 0.25 (0.13, 0.42), 0.26 (0.15, 0.41), and 0.44 (0.27, 0.63) (p linear trend = 0.73). Results remained similar after adjustment for female partner intake of dairy foods. Overall, men's dairy intake was not associated with treatment outcomes of couples undergoing ART. PMID:26825777

    Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor's belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs from nine different STEM departments at a midsized research university. Structural equation modeling reveals that K-12 teaching experience, hours and perceived quality of GTA PD, and perception of the departmental facilitating environment are significant factors that explain 32% of the variance in the teaching self-efficacy of STEM GTAs. This model highlights the important contributions of the departmental environment and GTA PD in the development of teaching self-efficacy for STEM GTAs. PMID:26250562

    2014-07-01

    From the early ages of assisted reproductive technologies (ARTs), different protocols have been developed with different gonadotropin preparations at different dosages with or without gonadotropin releasing hormone agonist or antagonist cotreatment. Various adjuvants have also been incorporated in controlled ovarian hyperstimulation (COH) protocols in an attempt to increase the efficacy and safety. The "best" protocol for COH should minimize stimulation burden while maintain the highest healthy, singleton, term live birth rates. Understandably, the one that meets all these expectations may not exist and COH should be individualized. Currently, there are worldwide differences in COH protocols and gonadotropin dose algorithms used depending on the country, demographics, funding stream, and existing guidelines/legislations. In 2014, despite efforts to individualize COH, currently, many of the protocols employ lack of high-quality evidence-based data. The aim of this review is to overview the efficacy and safety of available COH protocols, in normal responders, poor responders, and hyperresponders from evidence-based medicine perspective.

    The chorionicity-based evaluation of the perinatal risk in twin pregnancies after assisted reproductive technology (ART) is lacking. A retrospective review was performed of all twin pregnancies monitored prenatally and delivered at our hospital between 2010 and 2014. Chorionicity was diagnosed by ultrasound examination at first trimester and confirmed by postnatal pathology. Pregnancy and perinatal outcomes were prospectively recorded. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were calculated in a logistic regression model. A total of 1153 twin pregnancies were analyzed. The occurrence of preterm premature rupture of membranes (PPROM) was 3 times as frequent in monochorionic diamniotic (MCDA) twin pregnancies after ART as in those spontaneous counterparts (aOR 3.0; 95%CI 1.1-3.2). The prevalence of intrahepatic cholestasis of pregnancies (ICP) was significantly higher in dichorionic diamniotic (DCDA) twin pregnancies following ART compared to spontaneous DCDA pregnancies (aOR 3.3; 95%CI 1.3-5.6). Perinatal outcomes did not differ between two conception methods, either in MCDA or DCDA twin pregnancies. Based on differentiation of chorionicity, ART is associated with the increased risk of PPROM in MCDA twin pregnancies and with a higher rate of ICP in DCDA twin gestations. ART does not increase adversity of perinatal outcomes in twin pregnancies. PMID:27243373

    Clomiphene and assisted reproductive technologies (ART) are methods used to help subfertile couples become pregnant. ART has been reported to be associated with neural tube defects (NTDs) in offspring. To evaluate these associations, we studied mothers of 219 cases and 4,262 controls from the Slone Epidemiology Center Birth Defects Study (1993-2012) who were interviewed within 6 months after delivery about pregnancy events, including use of fertility treatments. We considered exposures to clomiphene (without ART) and ART during the periconceptional period. Logistic regression models were used to calculate adjusted odds ratios and 95% confidence intervals, controlling for education and study center. We observed elevated adjusted odds ratios of 2.1 (95% confidence interval: 0.9, 4.8) and 2.0 (95% confidence interval: 1.1, 3.6) for clomiphene and ART exposure, respectively. We performed a mediation analysis to assess whether the observed elevated NTD risk was mediated through multiple births. For clomiphene exposure without ART use, the direct effect estimate of the adjusted odds ratio (aORDE) was 1.7 and the indirect effect estimate (aORIE) was 1.4. Conversely, for ART exposure, the aORDE was 0.9 and the aORIE was 2.5. Our findings suggest that relatively little of the clomiphene-NTD association is mediated through the pathway of multiple births, while the ART-NTD association was explained by the multiple-births pathway.

    The use of Assisted Reproductive Technologies (ARTs) in modern cattle breeding is an important tool for improving the production of dairy and beef cattle. A frequently employed ART in the cattle industry is in vitro production of embryos. However, bovine in vitro produced embryos differ greatly from their in vivo produced counterparts in many facets, including developmental competence. The lower developmental capacity of these embryos could be due to the stress to which the gametes and/or embryos are exposed during in vitro embryo production, specifically ovarian hormonal stimulation, follicular aspiration, oocyte in vitro maturation in hormone supplemented medium, sperm handling, gamete cryopreservation, and culture of embryos. The negative effects of some ARTs on embryo development could, at least partially, be explained by disruption of the physiological epigenetic profile of the gametes and/or embryos. Here, we review the current literature with regard to the putative link between ARTs used in bovine reproduction and epigenetic disorders and changes in the expression profile of embryonic genes. Information on the relationship between reproductive biotechnologies and epigenetic disorders and aberrant gene expression in bovine embryos is limited and novel approaches are needed to explore ways in which ARTs can be improved to avoid epigenetic disorders.

    A nonexperimental design using a mailed questionnaire was used to answer five questions regarding allied health practitioners: What (1) present skills, (2) knowledge and (3) assistive technology (AT) competence do allied health practitioners have; what are (4) the AT skills and knowledge that allied health practitioners would like to obtain; and (5) how would these practitioners like to have AT education provided. More than two thirds of the subjects reported having nonexistent or foundational knowledge in most of the AT areas. Additionally, more than 50% of the respondents had a moderate or significant need for information in most areas of AT. No clear preferences regarding training options were revealed, other than a traditional classroom approach being the least attractive option. Most respondents are not willing to travel more than 1 hour from their home for AT education. This study revealed useful information for developing the content and format of AT education for allied health practitioners in Maine. We will expand this pilot study to investigate the AT educational needs of a wider variety of practitioners and consumers. PMID:12665293

    The aim of this review was to examine studies describing the psychological stress and adjustment in pregnancy after an assisted reproductive technology (ART) treatment. A systematic search of the electronic databases was performed. This review considered only quantitative, primary studies in the English language, published during the period 2000-2014 and relevant to the objective. The population of interest was previously infertile pregnant women. Outcome variables were general anxiety, depressive symptoms, pregnancy-specific anxiety, quality of life, self-esteem, pregnancy attitudes and adjustment, and maternal-fetal attachment. Twenty studies met the inclusion and methodological criteria and were included in the review. The review revealed that compared to women who conceive naturally or to general norms, women who conceive after an in vitro fertilization treatment had greater pregnancy-specific anxiety, poorer quality of life, either the same or less depressive symptomatology, the same level of self-esteem, more positive attitudes toward pregnancy demands, and higher levels of maternal-fetal attachment. However, the evidence regarding the general anxiety levels in pregnancy after an ART treatment was inconclusive. Methodological limitations and differences across studies may explain the inconsistencies in their findings regarding the impact of ART. This review provides an insight into psychological reactions and adjustment in pregnancy after an ART treatment. PMID:26212077

    Objectives. We assessed the association between assisted reproductive technology (ART) and diagnosed autistic disorder in a population-based sample of California births. Methods. We performed an observational cohort study using linked records from the California Birth Master Files for 1997 through 2007, the California Department of Developmental Services autism caseload for 1997 through 2011, and the Centers for Disease Control and Prevention’s National ART Surveillance System for live births in 1997 through 2007. Participants were all 5 926 251 live births, including 48 865 ART-originated infants and 32 922 cases of autism diagnosed by the Department of Developmental Services. We compared births originated using ART with births originated without ART for incidence of autism. Results. In the full population, the incidence of diagnosed autism was twice as high for ART as non-ART births. The association was diminished by excluding mothers unlikely to use ART; adjustment for demographic and adverse prenatal and perinatal outcomes reduced the association substantially, although statistical significance persisted for mothers aged 20 to 34 years. Conclusions. The association between ART and autism is primarily explained by adverse prenatal and perinatal outcomes and multiple births. PMID:25790396

    The assisted reproductive technologies, particularly in vitro fertilization (IVF), represent the most efficient and successful means of overcoming infertility associated with endometriosis. Although older studies suggest that IVF outcomes are compromised in endometriosis patients, more contemporary reports show no differences compared to controls. The exception may be evidence of poorer outcomes and diminished ovarian response in women with advanced disease, particularly those with significant ovarian involvement or prior ovarian surgery. Prolonged pre-IVF cycle suppressive medical therapy, particularly gonadotropin releasing hormone agonists, appears to improve success rates in a subset of endometriosis patients. However, as of yet, there is no diagnostic marker to specifically identify those who would most benefit from this approach. Pre-IVF cycle surgical resection of nonovarian disease has not been consistently shown to improve outcomes with the possible exception of resection of deeply invasive disease, although the data is limited. Precycle resection of ovarian endometriomas does not have benefit and should only be performed for gynecologic indications. Indeed, there is a large body of evidence to suggest that this procedure may have a deleterious impact on ovarian reserve and response. A dearth of appropriately designed trials makes development of definitive treatment paradigms challenging. PMID:26240824

    Unexplained recurrent miscarriage (RM) is a significant health problem for which no effective treatment is available yet. In only 50% of couples with RM a cause can be found. In clinical practice, a frequently asked question is whether assisted reproductive technology (ART) is a treatment option. The scientific rationale and the chances of success for ART in couples with unexplained RM are still controversial. Presently, there is not enough evidence to justify IVF or intrauterine insemination (IUI) as a treatment option. Research on oocyte donation has been reported in one article. It is questionable whether couples with unexplained RM would undergo the potential risks and emotional aspects of ART. There is insufficient data on whether preimplantation genetic diagnosis improves the live birthrate in carriers of a structural chromosome rearrangement with a history of RM. No randomized controlled trials are available for preimplantation genetic screening (PGS) for unexplained RM. A recently published review concluded that the live birthrate for IVF/PGS and natural conception groups appears to be quite similar. Because evidence is lacking, we recommend refraining from ART in couples with recurrent miscarriage. PMID:22161467

    During treatments with assisted reproductive technologies (ART), some men may have difficulties in producing spermatozoa on demand at the time of insemination, either for intrauterine insemination (IUI) or for in-vitro fertilization (IVF). This situation imposes tremendous stress on the couple and may cause cancellation of the treatment. Here we describe, for the first time, the use of sildenafil citrate (ViagraTM) for temporary erectile dysfunction in couples undergoing ART. The first case was a man who could not produce spermatozoa for the first IVF treatment after an exhausting trial for 12 h, despite the fact that he never had problems in providing sperm samples during previous IUI cycles. Using Viagra enabled him to provide spermatozoa, but the delay in oocyte insemination resulted in no embryonic development. This prompted us to be more alert to this option and to suggest the use of Viagra to men who had a history of erectile dysfunction during previous ART cycles. In these cases, the use of Viagra was planned in advance and it successfully solved any unpredictable erectile dysfunction on the day of insemination. Such cases emphasize the need to think in advance of this potential use of Viagra during ART. PMID:10402389

    The role of left ventricular assist devices (LVAD) in patients with end-stage heart failure is well known, both as a temporary treatment before transplantation and as destination therapy, in a scenario of a relative shortage of donors to satisfy the increasing requests for transplantation. The increased population of LVAD patients needs careful imaging assessment before, during, and after LVAD implantation; echocardiography is the best tool for their evaluation and is considered the diagnostic technique of choice for the assessment before, during, and after device implantation. Although the conventional echocardiographic assessment is quite effective in evaluating the main critical issues, the role of new technologies like three-dimensional echocardiography and myocardial deformation measurements is still not properly clarified. In this review, we aim to provide an overview of the main elements that should be considered in the assessment of these patients, underlining the role that could be played by new techniques to improve the diagnostic and prognostic effectiveness of echocardiography in this setting.

    Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor’s belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs from nine different STEM departments at a midsized research university. Structural equation modeling reveals that K–12 teaching experience, hours and perceived quality of GTA PD, and perception of the departmental facilitating environment are significant factors that explain 32% of the variance in the teaching self-efficacy of STEM GTAs. This model highlights the important contributions of the departmental environment and GTA PD in the development of teaching self-efficacy for STEM GTAs. PMID:26250562

    The new impending environmental law in Poland provides for strict environmental guidelines for coal preparation, washing, mine desalination, and application of commercially viable and economical clean coal technologies for utilization of coal. The government of Poland requested the U.S. Trade and Development Program (TDP) carry out a Definitional Mission to Poland to define the requirements of the Polish authorities and to prepare specific recommendations for follow on actions by TDP. The technical assistance package proposed to be funded by TDP includes two specific activities. These are (i) an orientation visit to review selected clean coal technology projects in the U.S., and (ii) preparation of a compendium of the main coal sector requirements in Poland and the types of technologies needed. The Definitional Mission has prepared a Scope of Work which recommends that TDP allocate a fund to finance the cost of the above technical assistance activities. It is further recommended that TDP enlist the assistance of a non-profit trade organization to provide this assistance to the Polish government.

    We studied an artificial intelligent assisted interaction between a computer and a human with severe speech and physical impairments (SSPI). In order to speed up AAC, we extended a former study of typing performance optimization using a framework that included head movement controlled assistive technology and an onscreen writing device. Quantitative and qualitative data were collected and analysed with mathematical methods, manual interpretation and semi-supervised machine video annotation. As the result of our research, in contrast to the former experiment's conclusions, we found that our participant had at least two different typing strategies. To maximize his communication efficiency, a more complex assistive tool is suggested, which takes the different methods into consideration. PMID:26294553

    Assistive technologies (ATs) for computer access enable people with disabilities to be included in the information society. Current methods for assessment and selection of the most appropriate AT for each individual are non standardized, lengthy, subjective, and require substantial clinical experience of a multidisciplinary team.This manuscript presents and evaluates an objective approach to test and select an appropriate AT for computer access for people with disabilities. Six user interfaces(standard keyboard, mini and large joystick, mini and large trackball, and head-operated mouse and keyboard) were tested on the control group of 29 people without disabilities and on 63 people with neuromuscular and muscular diseases, using purpose-built software for testing the speed of sentence typing. Different criteria for selecting the optimal AT were tested and compared with the skilled clinician's choice. The learning curves of the people with disabilities proved to follow those of the healthy controls, but with lower performance. Daily computer use was not associated with AT selection, but corresponded nearly perfectly to the level of functional ability of upper limbs. Agreement between clinician's choice and learning-based AT selection was noteworthy,but far from perfect. If partial agreement was taken into account, that is, AT was considered as an ordinal variable based on the corresponding functional ability level, and the second best learning-based choice was taken into account,the agreement was high for highest median typing speed as AT selection criterion. In conclusion, the developed method for AT assessment and selection seems to be an efficient guide for an unskilled clinician to choose an appropriate AT. PMID:20216223

    Assisted reproductive technologies (ART) predispose the offspring to vascular dysfunction, arterial hypertension, and hypoxic pulmonary hypertension. Recently, cardiac remodeling and dysfunction during fetal and early postnatal life have been reported in offspring of ART, but it is not known whether these cardiac alterations persist later in life and whether confounding factors contribute to this problem. We, therefore, assessed cardiac function and pulmonary artery pressure by echocardiography in 54 healthy children conceived by ART (mean age 11.5 ± 2.4 yr) and 54 age-matched (12.2 ± 2.3 yr) and sex-matched control children. Because ART is often associated with low birth weight and prematurity, two potential confounders associated with cardiac dysfunction, only singletons born with normal birth weight at term were studied. Moreover, because cardiac remodeling in infants conceived by ART was observed in utero, a situation associated with increased right heart load, we also assessed cardiac function during high-altitude exposure, a condition associated with hypoxic pulmonary hypertension-induced right ventricular overload. We found that, while at low altitude cardiac morphometry and function was not different between children conceived by ART and control children, under the stressful conditions of high-altitude-induced pressure overload and hypoxia, larger right ventricular end-diastolic area and diastolic dysfunction (evidenced by lower E-wave tissue Doppler velocity and A-wave tissue Doppler velocity of the lateral tricuspid annulus) were detectable in children and adolescents conceived by ART. In conclusion, right ventricular dysfunction persists in children and adolescents conceived by ART. These cardiac alterations appear to be related to ART per se rather than to low birth weight or prematurity. PMID:25979934

    Background: Based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) put on their main effects on the granulosa and theca cells. LH is essential for androgens production. Androgens are used for estradiol production by granulosa cells. Profound suppression of LH concentrations in some normogonadotropic patients can cause several adverse effects. Objective: The main clinical purpose of this study was that normoresponder women treated with controlled ovarian super ovulation for IVF or ICSI may benefit from co-administration of rLH. Materials and Methods: 40 patients who were candidates for assisted reproductive technology (ART) were randomly selected. In all patients long luteal protocol was used for ovulation induction. Patients were randomly divided into two groups: Group 1 (n=20) with standard long protocol (GnRH agonist) and r-FSH alone, Group 2 (n=20) with standard long protocol (GnRH agonist) and r-FSH with r-LH. Results were statistically analyzed and compared in two groups. Results: The number of retrieved oocytes, mature oocytes, cleaved embryos, transferred embryos, estradiol levels in Human chorionic gonadotropin (hCG) administration day, implantation rate and clinical pregnancy rate in group 2 were higher but not significantly different. Conclusion: Administration of rLH in late follicular phase had no beneficial effect on outcomes in young women with mean age of 31 years. Maybe a greater sample size should be used to see the effects more accurately; also it is possible that rLH will be useful in older patients.

    The first IVF baby, Louise Brown, was born in a natural cycle IVF of a woman who had bilateral tubal block making IVF the only option for having a child. The last 3 decades has seen astounding progress in the field of ART. Today thanks to ART, tubal disease and tubal factor infertility is easily overcome. The accepted theory today is that the hydrosalpinx fluid plays a causative role in the reduced pregnancy rate with ART. It is well known that the success of ART for patients with tubal disease with hydrosalpinx is reduced by half compared with patients without hydrosalpinx. Ideal would be removal of a hydrosalpinx by laparoscopic salpingectomy to improve pregnancy rates. However in some cases this is not feasible due to dense pelvic adhesions making access difficult. In such cases it is recommended that even de-linking the tube from the uterus would help in improving the ART outcome. There is suggestion that sonographically visible hydrosalpinges and those affected bilaterally have a poorer prognosis than those seen incidentally at laparoscopy. While there is clinical evidence supporting the causative role of the fluid itself, there is a lack of knowledge as to how the fluid exerts its negative effects. It is generally believed that the fluid holds a key position in impairing implantation potential. The aim of this review is to highlight the importance of identifying hydrosalpinges and its association with reduced fertility outcome using assisted reproductive technologies. Here we have discussed the different options available for the same, and highlighted the current modes of treatment. PMID:22442504

    DNA methylation is a key epigenetic modification which is essential for normal embryonic development. Major epigenetic reprogramming takes place during gametogenesis and in the early embryo; the complex DNA methylation patterns are established and maintained by DNA methyltransferases (DNMTs). However, the influence of assisted reproductive technologies (ART) on DNA methylation reprogramming enzymes has predominantly been studied in mice and less so in human oocytes and embryos. The expression and localization patterns of the four known DNMTs were analysed in human oocytes and IVF/ICSI embryos by immunocytochemistry and compared between a reference group of good quality fresh embryos and groups of abnormally developing embryos or embryo groups after cryopreservation. In humans, DNMT1o rather than DNMT1s seems to be the key player for maintaining methylation in early embryos. DNMT3b, rather than DNMT3a and DNMT3L, appears to ensure global DNA remethylation in the blastocysts before implantation. DNMT3L, an important regulator of maternal imprint methylation in mouse, was not detected in human oocytes (GV, MI and MII stage). Our study confirms the existence of species differences for mammalian DNA methylation enzymes. In poor quality fresh embryos, the switch towards nuclear DNMT3b expression was delayed and nuclear DNMT1, DNMT1s and DNMT3b expression was less common. Compared with the reference embryos, a smaller number of cryopreserved embryos showed nuclear DNMT1, while a delayed switch to nuclear DNMT3b and an extended DNMT1s temporal expression pattern were also observed. The spatial and temporal expression patterns of DNMTs seem to be disturbed in abnormally developing embryos and in embryos that have been cryopreserved. Further research must be performed in order to understand whether the potentially disturbed embryonic DNMT expression after cryopreservation has any long-term developmental consequences.

    The Society for Assisted Reproductive Technology (SART) method of embryo grad- ing is unique, simple, and widely practiced, and its use has been mandatory for SART membership programs since 2010. Developed by SART in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shift in clinical practice to be more selective and to transfer fewer embryos. This inspired us to conduct a review on the SART embryo grading system. In this retrospective study, the literature on evaluation of human embryo quality in gen- eral, and the SART method of evaluation in particular, were reviewed for the period of 2000 to 2014. A multifaceted search pertaining to methods of embryo grading and trans- fer using a combination of relevant terms [embryo, mammalian, embryo transfer, grade, grading, morphology, biomarkers, SART, and in vitro fertilization (IVF)] was performed. The inclusion and exclusion in this review were dictated by the aim and scope of the study. Two investigators independently assessed the studies and extracted information. A total of 61 articles were reviewed. Very few studies have evaluated the efficacy of the SART embryo grading method. The present study suggests the necessity for revision of the current SART grading system. The system, as it is now, lacks criteria for describing the cohort specific best embryo and thus is of limited use in single embryo transfer. The study foresees heightened descriptive efficiency of the SART system by implementing the proposed changes. Strengths and weaknesses of the SART embryo grading were identified. Ideas for selecting the best cohort-specific embryo have been discussed, which may trigger methodological improvement in SART and other embryo grading systems. PMID:27441045

We reviewed the medical records of 406 mothers with dichorionic twin pregnancies, who received continuous antenatal care from < or = 20 weeks of gestation and gave birth to infants after > or = 24 weeks of gestation in our institute. Birth defects were diagnosed at the time of hospital discharge according to the International Classification of Diseases, 10th Revision. Occurrence of birth defects was compared between twins conceived by ART and those conceived naturally using logistic regression analysis. Overall, 51 of 812 infants (51/812 = 6.2%) had birth defects. The incidence of birth defects in ART-conceived twins was significantly higher than that of naturally conceived twins with an odds ratio of 6.9 (95% confidence interval [CI] 2.1, 22.5), 3.7 (95% CI 1.2, 12.0), and 4.3 (95% CI 1.4, 14.3) for ICSI, IVF, and GIFT, respectively. The higher frequency of birth defects in ART-conceived twins was still significant after adjusting for higher maternal age in the ART group, with an adjusted odds ratio of 6.7 (95% CI 2.1, 21.9), 3.6 (95% CI 1.1, 11.5), and 3.7 (95% CI 1.2-11.8) for ICSI, IVF, and GIFT, respectively. Dichorionic twins conceived by ART, compared to dichorionic twins conceived naturally, had a much higher risk for birth defects diagnosed at hospital discharge. PMID:15193165

    Objective To investigate the risk of preterm birth among liveborn singletons to primiparas who conceived with assisted reproductive technology (ART) using four mutually exclusive categories of infertility (female infertility only, male infertility only, female and male infertility, and unexplained infertility) and to examine preterm birth risk along the gestational age continuum. Design Retrospective cohort study. Setting Not applicable. Patient(s) Singletons born to primiparas who conceived with or without ART. Intervention(s) None. Main Outcome Measure(s) Preterm (<37 weeks’ gestation) and preterm/early term birth <39 weeks’ gestation). Result(s) For the male infertility only, female infertility only, combined male and female infertility, and unexplained infertility groups, ART-conceived singletons were significantly more likely than non-ART singletons to be born preterm: adjusted odds ratio (aOR) 1.24 (95% CI, 1.13, 1.37), aOR 1.60 (95% CI, 1.50, 1.70), aOR 1.49 (95% CI, 1.35, 1.64), and aOR 1.26 (1.12, 1.43) respectively. Among infants whose mothers were diagnosed with infertility, the odds of preterm birth were highest between 28–30 weeks [female infertility only, aOR 1.95 (95% CI, 1.59, 2.39); male and female infertility: 2.21 (95% CI, 1.62, 3.00)] compared with infants in the general population. Within the ART population, singletons of couples with female infertility only were more likely to be born preterm than singletons born to couples with other infertility diagnoses. Conclusion(s) Among singleton births to primiparas, those conceived with ART had an increased risk for preterm birth, even when only the male partner had been diagnosed with infertility. The risk of preterm birth for ART-conceived infants whose mothers were diagnosed with infertility included the earliest deliveries. PMID:25707336

    CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients. To reach that threshold levels of follicle stimulating hormone, in a step-up protocol longer duration of stimulation is required in some cases so as to prevent multiple pregnancy and to eliminate the risk of ovarian hyperstimulation syndrome. AIM: To evaluate the duration of stimulation, quality of oocytes, and embryo, and the pregnancy outcome in the assisted reproductive technology (ART) cycles in patients with HH. MATERIALS AND METHODS: Over the period of 4 years, we had 14 patients with HH in whom 21 cycles of ovulation induction were done. Of these 7 patients underwent oocyte retrieval and intracytoplasmic sperm injection (ICSI). We present a retrospective study of these 7 patients who underwent ART to evaluate the duration of stimulation, quality of oocytes and embryo, and the pregnancy outcome. RESULTS: In the study group on ovulation induction with gonadotropins, only one patient had the duration of stimulation of the standard 12 days, the remaining 6 patients took ≥12 days to respond to stimulation (maxium being 54 days). Mean ET in these patients was 8.9 mm. Six patients had >70% good quality MII oocytes. One patient responded poorly and had only 2 good quality MII oocytes (50%). After ICSI procedure, resultant embryos were of grade 1 and 2 in all the patients irrespective of the duration of stimulation. Fertilization rate in these patients was 85% (except in one 50% fertilization rate), and the cumulative pregnancy rate was 68.6%. CONCLUSION: In the patients with HH the quality of oocytes and embryos, and the pregnancy rate is not affected even if the duration of stimulation is prolonged. PMID:26538857
