Abstract
LAY SUMMARY Female Veterans and female athletes with disabilities express concerns with mobility devices that are male-centric and do not address their unique needs. It is important that the needs of women are given the same attention as those of men. The following study asked groups of women who use wheelchairs or scooters, including Veterans and athletes, about their experiences. Twenty-four women, recruited from two sporting events for Veterans with disabilities, were asked to fill out a survey and participate in a focus group where they would discuss their views on mobility aids and related services. There were four major themes women often mentioned when they talked about using their mobility aids: usability (how they like using it), service delivery (how they get help with it), well-being (how they feel), and design (how it looks and works). Participants were concerned about the ability to adjust their device to their needs, how people obtained a device, and how they felt about using the device. Female wheelchair and scooter users recommended several changes to mobility aids that would improve the devices and improve the lives of women who use them.

Abstract
LAY SUMMARY Mobility assistive technology (AT) can improve the lives of people with disabilities by helping them get around in their communities. Today, over 23.9 million Americans use a wheelchair or assistive device, and over 85,000 wheelchairs, scooters, or other mobility devices are provided to Veterans each year. In order to find out how people learn about AT to improve efforts to disseminate information about AT, a survey of people who use mobility AT was conducted. The majority of people who completed the survey were Veterans (82%). It was determined that these people most often learned about AT through other users and/or from Veterans and the Internet, and that some people wish to receive information in other ways. Researchers can use these findings to better reach the people who could benefit from the new mobility AT they are creating.

Abstract
Introduction A total of 3.6 million Americans and over 250,000 veterans use wheelchairs. The need for advancements in mobility-assistive technologies is continually growing due to advances in medicine and rehabilitation that preserve and prolong the lives of people with disabilities, increases in the senior population, and increases in the number of veterans and civilians involved in conflict situations. The purpose of this study is to survey a large sample of veterans and other consumers with disabilities who use mobility-assistive technologies to identify priorities for future research and development. Materials and Methods This survey asked participants to provide opinions on the importance of developing various mobility-assistive technologies and to rank the importance of certain technologies. Participants were also asked to provide open-ended comments and suggestions. Results A total of 1,022 individuals, including 500 veterans, from 49 states within the USA and Puerto Rico completed the survey. The average age of respondents was 54.3 yr, and they represented both new and experienced users of mobility-assistive technologies. The largest diagnostic group was spinal cord injury (SCI) (N = 491, 48.0%). Several themes on critical areas of research emerged from the open-ended questions, which generated a total of 1,199 comments. Conclusion This survey revealed several themes for future research and development. Advanced wheelchair design, smart device applications, human-machine interfaces, and assistive robotics and intelligent systems emerged as priorities. Survey results also demonstrated the importance for researchers to understand the effects of policy and cost on translational research and to be involved in educating both consumers and providers.

Abstract
PURPOSE The purpose of this study was to evaluate the opinions of providers of mobility assistive technologies to help inform a research agenda and set priorities. MATERIALS AND METHODS This survey study was anonymous and gathered opinions of individuals who participate in the process to provide wheelchairs and other assistive technologies to clients. Participants were asked to rank the importance of developing various technologies and rank items against each other in terms of order of importance. Participants were also asked to respond to several open-ended questions or statements. RESULTS A total of 161 providers from 35 states within the USA consented to participation and completed the survey. CONCLUSIONS This survey revealed themes of advanced wheelchair design, assistive robotics and intelligent systems, human machine interfaces and smart device applications. It also outlined priorities for researchers to provide continuing education to clients and providers. These themes will be used to develop research and development priorities. Implications for Rehabilitation • Research in advanced wheelchair design is needed to facilitate travel and environmental access with wheelchairs and to develop alternative power sources for wheelchairs.• New assistive robotics and intelligent systems are needed to help wheelchairs overcome obstacles or self-adjust, assist wheelchair navigation in the community, assist caregivers and transfers, and aid ambulation.• Innovations in human machine interfaces may help advance the control of mobility devices and robots with the brain, eye movements, facial gesture recognition or other systems.• Development of new smart devices is needed for better control of the environment, monitoring activity and promoting healthy behaviours.

Abstract
Objective: The overall objective of this project was to identify consumers' opinions of their needs and wants related to assistive technology (AT) in a systematic and quantitative manner via a questionnaire that can be used to validate existing and establish new research priorities. Methods: This pilot study describes questionnaire development, online implementation, and revisions considered to the questionnaire in preparation for conducting a nationwide survey. Data from a sample (N = 112) are presented. The pilot study was critical to refine the questions and ensure that meaningful information was being collected. Results: It was identified that revisions were warranted to provide more structure and allow for consumers to prioritize AT research efforts. Conclusion: The questionnaire results, although positively in favor of many of the technologies presented, are inconclusive to identify generalizable research priorities, thus expansion to a nationwide population is warranted.

Abstract
Disparities exist in breast cancer knowledge and education, which tend to influence symptom interpretation and decision to seek screening/care. The present project describes a cohort of women's experiences, knowledge, and health behavior prior to and after a diagnosis of breast cancer. It also studies how knowledge and demographic factors are associated with level of involvement participants had in the treatment of their breast cancer. Women >18 years who have been diagnosed and treated for breast cancer within 10 years were recruited in Pittsburgh, PA, through the Healthy People Cohort Registry, a database of volunteers from the community, and Brooklyn, NY, through the American Cancer Society breast cancer survivor database. Subsequent to institutional ethics approval, a questionnaire was administered by mail and through an electronic interactive format. The study included 124 breast cancer survivors, one-quarter of whom were of African ancestry. Roughly half of the women indicated that their overall knowledge of breast cancer was limited before diagnosis; no significant association between overall knowledge before diagnosis and stage at diagnosis or an active role of the patient in treatment choices was observed. Two-third of the women reported using personal research on internet, books, and other media to increase knowledge on breast cancer after diagnosis; the improvement of knowledge was associated with an active role in therapy choice. White women's self report of breast cancer knowledge prior to diagnosis was higher than that of women of African origin (p = 0.03); the latter experienced more delays in getting results about the diagnosis (p = 0.002), in starting treatment (p = 0.03), and in having treatment available at local facilities (p = 0.007) than white women. White women were more likely to improve their knowledge through their own research (p = 0.08) and through the contribution of their physician (p = 0.06) than women of African origin.There is still a need for addressing breast cancer knowledge among black women, and improvement in physician emotional support and in their contribution to the patient's knowledge is necessary. These efforts may have a positive impact on breast cancer knowledge among black women in the US.

Abstract
BACKGROUND High-risk (HR) HPV genotypes other than 16 and 18 have been detected in a significant proportion of immunocompromised females. We aim to evaluate the frequency of HR HPV genotypes in a population of HIV-positive Caribbean women. METHODS One hundred sixty-seven consecutive, non-pregnant, HIV-positive females ≥18 years were recruited in this study. Each participant received a vaginal examination, PAP smear, and completed a questionnaire. DNA was extracted for HPV testing in 86 patients. RESULTS Mean age was 39.1 years for women positive for HR HPV and 43.1 years for women negative for HR HPV (P value = 0.040). 78% (130/167) of the women had HR HPV infections; the prevalence of abnormal cervical cytology was 38% among women who were HR HPV-positive compared to women who were HR HPV-negative (22%). Fifty-one percent of the 86 women with available genotype carried infections with HPV 16 and/or HPV 18; genotypes of unknown risk were also frequently observed. Women who had a CD4+ count of ≤200 had 7 times increased odds of carrying HR HPV infection in comparison to women with CD4+>200. CONCLUSIONS HR HPV infections in HIV infected females may consist of more than just HPV 16 and 18, but also HPV 52 and 58. Further studies are needed to determine whether HPV 52 and 58 play a significant role in the development of cervical cytological abnormalities in HIV+ women.

Abstract
Background: It has been demonstrated in immunocompromised females that HR HPV genotypes other than 16 and 18 have been detected in a significant proportion of these individuals. We aim to evaluate the frequency of HR HPV genotypes in a population of HIV-positive Caribbean women, detect characteristics associated with HR HPV infections other than HPV16 and 18, and investigate the clustering of HPV genotypes in this population.
Methods: One hundred and seventy-six non-pregnant, HIV-positive females ≥18 years were recruited. Each participant received a vaginal examination and completed a questionnaire.
Results: Mean age was 38.7 years for women positive for HR HPV and 44.4 years for women negative for HR HPV (P value = 0.0018). The majority of the HR HPV-positive women were on HAART for 2-4 years. Non-negative matrix factorization identified HPV 16, 18, 52 and 58 as the most influential HPV high-risk types. Among the women who were HIV+ for more than 2 years, secondary CART analysis revealed those aged ≤29 had statistically significant different cervical abnormality profile compared to women >29 years; specifically, younger women were more likely to have dysplasia, while older women had normal cervical cytology. Also, the mean number of years on HAART for ≤29 years old was only 1 year (std dev. ±1.3) while those >29 years old the mean was 3.6 years (std. dev. ± 2.5) (p = 0.009).
Conclusions: HR HPV in the immunocompromised female consists of more than just HPV 16 and 18, but also types HPV 52 and 58, which are likely to influence the course of HPV infections and the development of cervical cytological abnormalities. Targeted interventions to boost treatment compliance among HIV- positive women are needed to reduce the risk of cervical abnormalities.

Abstract
Background Disparities in cervical cancer incidence and mortality rates exist among women of African ancestry (African-American, African-Caribbean and African). Persistent cervical infection with Human papillomavirus (HPV) is associated with cervical dysplasia and if untreated, could potentially progress to invasive cervical cancer. Very few studies have been conducted to examine the true prevalence of HPV infection in this population. Comparisons of cervical HPV infection and the type-specific distribution of HPV were performed between cancer-free Caribbean and US women. Results The Caribbean population consisted of 212 women from Tobago and 99 women from Jamaica. The US population tested, consisted of 82 women from Pittsburgh. The majority of the US subjects was Caucasian, 74% (61/82) while 12% (10/82) and 13% (11/82) were African-American or other ethnic groups, respectively. The age-adjusted prevalence of any HPV infection among women from Tobago was 35%, while for Jamaica, it was 81% (p < 0.0001). The age-adjusted prevalence of HPV infection for Caribbean subjects was not statistically significantly different from the US (any HPV: 47% vs. 39%, p > 0.1; high-risk HPVs: 27% vs. 25%, p > 0.1); no difference was observed between US-Blacks and Jamaicans (any HPV: 92% vs. 81%, p > 0.1; high-risk HPV: 50% vs. 53%, p > 0.1). However, US-Whites had a lower age-adjusted prevalence of HPV infections compared to Jamaican subjects (any HPV: 29% vs. 81%, p < 0.0001; high-risk HPV: 20% vs. 53%, p < 0.001). Subjects from Jamaica, Tobago, and US-Blacks had a higher proportion of high-risk HPV infections (Tobago: 20%, Jamaica: 58%, US-Blacks: 40%) compared to US-Whites (15%). Similar observations were made for the presence of infections with multiple high-risk HPV types (Tobago: 12%, Jamaica: 43%, US-Blacks: 30%, US-Whites: 8%). Although we observed similar prevalence of HPV16 infections among Caribbean and US-White women, there was a distinct distribution of high-risk HPV types when comparisons were made between the ethnic groups. Conclusion The higher prevalence of cervical HPV infections and multiple high-risk infections in Caribbean and US-Black women may contribute to the high incidence and prevalence of cervical cancer in these populations. Evaluation of a larger sample size is currently ongoing to confirm the distinct distribution of HPV types between ethnic groups.

Abstract
This paper demonstrates the first steps of an automation process to develop models of signal transduction pathways using discrete modelling languages. The whole approach consists of modelling, validation, animation, linking databases to simulation tools and also the qualitative analysis of the data. In this paper, we detail the modelling and simulation of the TLR4 pathway with a coloured petri net simulation tool and the validation of this model against the semantic and mechanistic map from a biological database. These graphical maps contain all necessary reactions as a figure. We start with an UML class diagram to understand the static structure of molecules involved in the TLR4 pathway. Afterwards we model and simulate each "pathway step reaction" - one after another - to get the behaviour of the final system. The result is a model of the pathway which can be used in simulations, derived solely from basic chemical reactions in the database. Also, it is a lesson on critical points where human decision-making is needed, because not all the required information is stored directly in the database.

Abstract
Few data exist regarding the clonal identity of Staphylococcus aureus (SA) that colonises the nostrils and causes exit-site infections in peritoneal dialysis patients. Nasal and exit-site swabs were taken monthly from 41 patients undergoing peritoneal dialysis, and a genetic analysis of SA isolates was performed by pulsed-field-gel electrophoresis. When SA was identified at the exit-site, the clonal identity of nasal and exit-site isolates was demonstrated. In 50% of the SA carriers, nasal isolates were genetically constant over time; in the other 50% a change of colonising SA strains was observed. The risk of exit-site infection was identical in both groups.

Abstract
PURPOSE Ultrasound is often applied in the course of treatment after knee arthroplasty, although sonographic normal findings have not been described so far. Characterising these and comparing them to clinical disorders was the purpose of this study. Intra- and extra-articular hematoma and the imaging of the traumatised extension apparatus of the knee joint were of special interest. METHODS During 4 weeks all consecutive patients after knee arthroplasty were examined clinically and sonographically. Furthermore, the blood parameters were controlled for signs of inflammation or coagulation disorders. These findings were then re-checked before the end of hospital rehabilitation treatment. RESULTS In all of the patients, ultrasound revealed intra-articular fluid at the beginning and at the end of hospital treatment. The fluid area, differing in extension, was markedly reduced or showed less echogenicity concomitant with an organisation. The patellar tendon in all of the patients showed a loss of echogenicity at the site of operative incision, mostly at the patellar insertion, and a thickening extending throughout the middle part of the tendon even at control. Dynamic ultrasound examination displayed one case of a major defect which had to be revised. Blood parameters of inflammation were decreased, coagulation parameters were normal. CONCLUSION After knee arthoplasty, extended intra-articular knee hematomas are not rare, only being resorbed or organised to a small degree during a rehabilitation period of three weeks, therefore not yielding relevant information for the course of treatment. CLINICAL RELEVANCE The patellar ligaments show alterations comparable to acute tendopathy, thus not recommending use of maximal forces or too high stretching of the tendon tissue. Soft tissue defects with the need for interruption of the rehabilitation programme may be detected sonographically. Further studies will be necessary to explore the course of restructuring. Disorders of patellar sliding movement and signs of prosthetic loosening cannot be sufficiently judged at the present time.

Abstract
BACKGROUND The electroretinogram (ERG) ist an important examination method for the evaluation of retinal dysfunction in children. However it is often difficult and sometimes almost impossible to examine especially younger children with usual methods. Because of its risks, general anesthesia is rarely used. METHODS ERG examinations were performed without general anesthesia or sedation with DTL (Dawson-Trick-Litzkow) electrodes. These are conjunctival electrodes made of thin microfibers. Several additional modifications of the standard examination technique were utilized, which enabled us to examine children of almost any age. 10 volunteers and 34 children between 6 month and 9 years of age were examined. RESULTS 62 eyes of 34 children were evaluated. The diagnostic problem could be solved in three quarters of the patients with the ERG. CONCLUSION With the DTL electrode and some methodical changes in the standard ERG technique it is possible to perform ERG's in little children without anesthesia or sedation. This method can be applied in children over 2 years of age. Below this age an sedation of any kind is necessary.
