Diabetes is a leading cause of blindness in the working age population. While optometrists have an established role in screening people with known diabetes for eye disease, their role in screening for diabetes has not been evaluated. For diabetes screening in optometry practices to be successful it must be acceptable to both optometrists and to the public. The purpose of this study was to determine acceptability to people attending optometry practices of using random capillary blood glucose (rCBG) tests to detect raised blood glucose levels in optometry practices. A screening service offering people with risk factors or symptoms of diabetes rCBG tests was piloted in five high street opticians' practices in North East England. One thousand and two people used the screening service during a 20 week period. Each was given a questionnaire to complete and return following a rCBG test. Nine hundred and thirty-nine questionnaires were returned (return rate 93.7%). The mean age of participants was 54.5 years, 63.3% were female and 75.0% had not been screened for diabetes previously. 99.1% agreed or strongly agreed that the location was convenient for them and 98.0% would recommend others to use the screening service. 83.8% of the participants would not have gone elsewhere to have any tests done and 148 (16.2%) responded that they would have sought a test elsewhere; 14.2% at the GP, 0.8% at a pharmacy and 0.5% elsewhere. Only 3.2% reported that the test procedure was uncomfortable.   To those attending opticians' practices, screening using rCBG tests is acceptable in terms of convenience and test comfort, and they would recommend the test to others. Screening in optometry practices provides an opportunity to identify people at risk of diabetes in a hitherto unutilised setting.

The New York State optometry workforce study.

PubMed

Soroka, Mort

2012-04-01

This study presents an analysis of the current optometry workforce, both as a unique profession and more broadly within the context of all eye care providers (optometry and ophthalmology) in New York State. The supply and distribution of eye care practitioners provides useful information for policy makers while providing insights as to the impact of the one optometry school within the state. Several databases were employed and a web based survey was developed for completion by all optometrists. The questionnaire included demographic data, whether they were actively practicing in New York State or any other state, were they full time or part time, their primary mode of practice, or if they provided care within institutional settings. Access to care was gauged by the respondents' availability for appointments during evenings or weekends. Access to eye care services in New York State has improved significantly during the past 30 years as the supply of optometrists increased. Before this study was conducted it was generally believed that there were more optometrists than ophthalmologists in every state of the nation except New York, Maryland and the District of Columbia. Findings of this study demonstrate there are 37% more optometrists in New York State than ophthalmologists and more evenly distributed as optometrists are located in almost every county of the state. Sixteen counties have no ophthalmologists. This is attributed to the presence of the College of Optometry established in 1971. More than 60% of all optometrists in the state are SUNY College of Optometry graduates.

To characterize utilization of office-based optometry services by immigration status using a nationally representative database. The 2007 to 2011 Medical Expenditure Panel Survey is used to examine adults aged 18 years and older. Respondents were classified as US natives, naturalized citizens, and noncitizens. Multivariate logistic regression analysis examined the relationship of having visited an office-based optometrist within the past 12 months by immigrant status, adjusting for age, sex, education, race/ethnicity, marital status, self-reported vision difficulty, use of corrective lenses, poverty status, insurance, language barrier and usual source of care. Oaxaca-Blinder decomposition identified factors that perpetuate or ameliorate disparities in utilization across immigrant groups. The proportion of US natives who had visited an optometrist within the past year was 7.2%, almost three times higher than that for noncitizens (2.5%). Among respondents who reported vision difficulties, only 47.9% of noncitizens used corrective lenses compared with 71.0% of naturalized citizens and 71.6% of US natives. Adjusting for confounding factors, multivariate logistic regression showed that naturalized citizens and noncitizen residents had significantly lower odds than US natives of receiving optometry services (naturalized citizen adjusted odds ratio, 0.77; 95% confidence interval, 0.66 to 0.89; noncitizen adjusted odds ratio, 0.44; 95% confidence interval, 0.36 to 0.53). Decomposition analysis suggested that 17% of the disparity in utilization between noncitizens and US natives resulted from barriers to care such as language barriers, poverty, lack of insurance, and not having a usual source of health care. Prior literature suggests that immigrants have significantly poorer clinical vision outcomes than US natives. Our findings suggest that this disparity in clinical vision outcomes may result from underutilization of optometry services by immigrants compared with US natives. Immigrant patients may need targeted interventions that reduce barriers to care and change their perceptions so that regular eye care services are viewed as necessary and preventative.

Purpose To describe a quality improvement for referral of National Health Service patients with macular disorders from a community optometry setting in an urban area. Methods Service evaluation of teleophthalmology consultation based on spectral domain optical coherence tomography images acquired by the community optometrist and transmitted to hospital eye services. Results Fifty patients with suspected macular conditions were managed via telemedicine consultation over 1 year. Responses were provided by hospital eye service-based ophthalmologists to the community optometrist or patient within the next day in 48 cases (96%) and in 34 (68%) patients on the same day. In the consensus opinion of the optometrist and ophthalmologist, 33 (66%) patients required further “face-to-face” medical examination and were triaged on clinical urgency. Seventeen cases (34%) were managed in the community and are a potential cost improvement. Specialty trainees were supervised in telemedicine consultations. Conclusion Innovation and quality improvement were demonstrated in both optometry to ophthalmology referrals and in primary optometric care by use of telemedicine with spectral domain optical coherence tomography images. E-referral of spectral domain optical coherence tomography images assists triage of macular patients and swifter care of urgent cases. Teleophthalmology is also, in the authors’ opinion, a tool to improve interdisciplinary professional working with community optometrists. Implications for progress are discussed. PMID:22174576

A common response to rising demand for healthcare is to extend the role of health professionals and the range of their service provision. Community optometry in Scotland is a recent example of this. Within this context of innovation and change there are challenges to ensuring quality in optometry practice. The purpose of this research is to establish what the priorities are for practice improvement within community optometry and to start a programme to inform strategies to improve practice. A four stage study was conducted: (1) a service-driven topic prioritisation exercise to identify priorities for optometry practice improvement; (2) a review of national and international guidance and UK protocols relating to the identified priority topic; (3) a national theory-based survey identifying current practice and the barriers and facilitators to the target behaviour; and (4) the identification of theory-based intervention options to improve practice. The Behaviour Change Wheel approach to behaviour change intervention development and Theoretical Domains Framework (TDF) provided the underlying theoretical framework. Stakeholders identified 'patients presenting with flashes and floaters' as an important priority for practice improvement. The decision about whether or not to refer patients on to secondary care for further examination is the target behaviour. Guidance for optometrists on this topic is lacking. Six TDF domains were related to the decision about whether or not to refer patients with flashes and floaters to secondary care - 'social influences', 'emotion', 'beliefs about capabilities', 'beliefs about consequences', 'behavioural regulation' and 'reinforcement'. This study has examined current practice in relation to the management of patients with flashes and floaters, identified the most salient targets for future strategies to improve optometry practice and highlighted what form these strategies may take. It demonstrates the use of a flexible, theory-informed approach, which can be used to engage with stakeholders and professionals to inform the design and development of efforts to improve practice in a variety of healthcare settings. © 2018 The Authors.

Since the introduction of angiogenesis as a useful target for cancer therapy, few agents have been approved for clinical use due to the rapid development of resistance. This problem can be minimized by simultaneous targeting of multiple angiogenesis signaling pathways, a potential strategy in cancer management known as polypharmacology. The current study aimed at exploring the anti-angiogenic activity of OSU-A9, an indole-3-carbinol-derived pleotropic agent that targets mainly Akt–nuclear factor-kappa B (NF-κB) signaling which regulates many key players of angiogenesis such as vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs). Human umbilical vein endothelial cells (HUVECs) were used to studymore » the in vitro anti-angiogenic effect of OSU-A9 on several key steps of angiogenesis. Results showed that OSU-A9 effectively inhibited cell proliferation and induced apoptosis and cell cycle arrest in HUVECs. Besides, OSU-A9 inhibited angiogenesis as evidenced by abrogation of migration/invasion and Matrigel tube formation in HUVECs and attenuation of the in vivo neovascularization in the chicken chorioallantoic membrane assay. Mechanistically, Western blot, RT-PCR and ELISA analyses showed the ability of OSU-A9 to inhibit MMP-2 production and VEGF expression induced by hypoxia or phorbol-12-myristyl-13-acetate. Furthermore, dual inhibition of Akt–NF-κB and mitogen-activated protein kinase (MAPK) signaling, the key regulators of angiogenesis, was observed. Together, the current study highlights evidences for the promising anti-angiogenic activity of OSU-A9, at least in part through the inhibition of Akt–NF-κB and MAPK signaling and their consequent inhibition of VEGF and MMP-2. These findings support OSU-A9's clinical promise as a component of anticancer therapy. - Highlights: • The antiangiogenic activity of OSU-A9 in HUVECs was explored. • OSU-A9 inhibited HUVECs proliferation, migration, invasion and tube formation. • OSU-A9 targeted signaling pathways mediated by Akt-NF-kB, VEGF, and MMP-2. • The anti-angiogenic activity of OSU-A9 supports its clinical promise.« less

The OSU1/QUA2/TSD2-Encoded Putative Methyltransferase Is a Critical Modulator of Carbon and Nitrogen Nutrient Balance Response in Arabidopsis

PubMed Central

Zheng, Zhi-Liang

2008-01-01

The balance between carbon (C) and nitrogen (N) nutrients must be tightly coordinated so that cells can optimize their opportunity for metabolism, growth and development. However, the C and N nutrient balance perception and signaling mechanism remains poorly understood. Here, we report the isolation and characterization of two allelic oversensitive to sugar1 mutants (osu1-1, osu1-2) in Arabidopsis thaliana. Using the cotyledon anthocyanin accumulation and root growth inhibition assays, we show that the osu1 mutants are more sensitive than wild-type to both of the imbalanced C/N conditions, high C/low N and low C/high N. However, under the balanced C/N conditions (low C/low N or high C/high N), the osu1 mutants have similar anthocyanin levels and root lengths as wild-type. Consistently, the genes encoding two MYB transcription factors (MYB75 and MYB90) and an Asn synthetase isoform (ASN1) are strongly up-regulated by the OSU1 mutation in response to high C/low N and low C/high N, respectively. Furthermore, the enhanced sensitivity of osu1-1 to high C/low N with respect to anthocyanin accumulation but not root growth inhibition can be suppressed by co-suppression of MYB75, indicating that MYB75 acts downstream of OSU1 in the high C/low N imbalance response. Map-based cloning reveals that OSU1 encodes a member of a large family of putative methyltransferases and is allelic to the recently reported QUA2/TSD2 locus identified in genetic screens for cell-adhesion-defective mutants. Accumulation of OSU1/QUA2/TSD2 transcript was not regulated by C and N balance, but the OSU1 promoter was slightly more active in the vascular system. Taken together, our results show that the OSU1/QUA2/TSD2-encoded putative methyltransferase is required for normal C/N nutrient balance response in plants. PMID:18167546

"Eye-T": information technology adoption and use in Canada's optometry practices.

While information technology (IT) is playing an increasing role in the delivery of optometric services, little specific information is available about how IT is changing the practice of optometry in Canada or whether optometry schools are adequately preparing their students to use this technology when they graduate. Quantitative data on how IT is being used, as well as related barriers and potential benefits, were obtained in a survey of Canadian optometrists (N = 474). Three site visits were made to geographically dispersed Canadian optometry practices identified as exemplars of IT adoption. More than 96% of Canadian optometrists use computers in their practices, but fewer have integrated computers into their examination rooms. Optometrists are regularly using computers to manage their practices and medical record keeping. The automated perimeter is the clinical assessment technology most used (88.4%), followed by the autorefractor (83.9%) and the autokeratometer (72.2%). The anterior segment camera is the technology most likely to be acquired within the next 5 years (36.9%), followed by the scanning laser ophthalmoscope (26.8%). Major benefits of IT for optometrists include being better able to provide patients with images and information to explain results and to inspire greater patient confidence that the practice is state of the art. Perceived barriers include the need for frequent updates, lack of resources for training, and cost. There is support for increased exposure to IT as part of training in optometry. Use of IT in optometry practices is widespread and likely to continue to increase in the years ahead. IT may be a key element in the future success of optometry practices in an increasingly competitive marketplace. Perceptions of high investment and training costs are barriers to further adoption. Optometrists may benefit from increased exposure to IT as part of their training. Copyright © 2010 American Optometric Association. Published by Elsevier Inc. All rights reserved.

Young Adults at Risk for Stimulant Dependence show Reward Dysfunction during Reinforcement-Based Decision Making

2012-01-01

Background While stimulant dependent individuals continue to make risky decisions in spite of poor outcomes, much less is known about decision-making characteristics of occasional stimulant users (OSU) at risk for developing stimulant dependence. This study examines whether OSU exhibit inefficient learning and execution of reinforced decision-outcome contingencies. Methods OSU (n=161) and stimulant-naïve comparison subjects (CTL; n=48) performed a Paper Scissors Rock task during functional magnetic resonance imaging. Selecting a particular option was associated with a pre-determined probability of winning, which was altered repeatedly to examine neural and behavioral characteristics of reinforced contingencies. Results OSU displayed greater anterior insula, inferior frontal gyrus (IFG), and dorsal striatum activation than CTL during late trials when contingencies were familiar (as opposed to being learned) in the presence of comparable behavioral performance in both groups. Follow-up analyses demonstrated that during late trials: (1) OSU with high cannabis use displayed greater activation in these brain regions than CTL, whereas OSU with low cannabis use did not differ from the other two groups; and (2) OSU preferring cocaine exhibited greater anterior insula, IFG, and dorsal striatum activation than CTL and also displayed higher activation in the former two regions than OSU who preferred prescription stimulants. Conclusions OSU exhibit inefficient resource allocation during the execution of reinforced contingencies that may be a result of additive effects of cocaine and cannabis use. A critical next step is to establish whether this inefficiency predicts transition to stimulant dependence. PMID:23021534

Indole-3-carbinol (I3C), a naturally occurring phytochemical found in cruciferous vegetables, has received much attention due to its translational potential in cancer prevention and therapy. In this study, we investigated the antitumor effects of OSU-A9, a structurally optimized I3C derivative, in a panel of oral squamous cell carcinoma cell lines, SCC4, SCC15, and SCC2095. The antiproliferative effect of OSU-A9 was approximately two-orders-of-magnitude higher than that of I3C. Importantly, normal human oral keratinocytes were less sensitive to OSU-A9 than oral cancer cells. This antiproliferative effect of OSU-A9 was attributable to the induction of mitochondrial-dependent apoptosis as evidenced by sub-G1 accumulation of cells, poly ADP-ribose polymerase cleavage, and cytochrome c release from the mitochondria. OSU-A9 down regulates Akt and NF-κB signaling pathways, leading to changes in many downstream effectors involved in regulating cell cycle and apoptosis. Moreover, the observed down regulation of IKKα and IKKβ expression by OSU-A9 is not reported for I3C. OSU-A9 also induces both the production of reactive oxygen species and the endoplasmic reticulum stress. Taken together, these results suggest the translational value of OSU-A9 in oral squamous cell cancer therapy in the future. Copyright © 2010 Elsevier Ltd. All rights reserved.

History of community health center affiliations with The New England College of Optometry.

PubMed

Wilson, Roger; Sharda, Vandhana

2008-10-01

Since the 1970s, The New England College of Optometry (NECO) has been a leader in community-based educational programming. This was accomplished through the development of affiliation agreements with health care facilities that care for the underserved, notably community health centers (CHCs). The college's clinical system, the New England Eye Institute (NEEI), develops CHC programs, manages professional services agreements, initiates teaching affiliation agreements, and leads staff recruitment and retention efforts. CHC collaborations, which effectively address disparities in access to health care and visual health status, represent a significant component of the college's primary care clinical training venues. Since their inception in 1972, these CHC academic-community partnerships have provided more than 650,000 eye examinations to the underserved and have trained more than 3,200 graduates in community-based eye care, interdisciplinary care management environment, clinical prevention strategies, and population health. This report describes NECO's longstanding success with CHCs, explains the scope of practice at CHCs, explains how students are involved in the CHCs' eye care services, and discusses the various management and business arrangements. The benefits and challenges of CHC affiliations with optometry schools and colleges are also discussed.

The effects of the dopamine stabilizer (-)-OSU6162 on aggressive and sexual behavior in rodents.

The dopamine stabilizer (-)-OSU61612 dampens locomotion in rodents rendered hyperactive by exposure to a novel environment or treatment with amphetamine, but stimulates locomotion in habituated animals displaying low motor activity, tentatively exerting this profile by selectively blocking extrasynaptic D2 receptors. The major aim of the present study was to explore the possible usefulness of (-)-OSU61612 as an anti-aggressive drug. To this end, the effect of (-)-OSU61612 on isolation-induced aggression in male mice and estrous cycle-dependent aggression in female rats were studied using the resident intruder test; in addition, the possible influence of (-)-OSU61612 on sexual behavior in male mice and on elevated plus maze (EPM) performance in male rats were assessed. (-)-OSU61612 at doses influencing neither locomotion nor sexual activity reduced aggression in male mice. The effect was observed also in serotonin-depleted animals and is hence probably not caused by the antagonism of serotonin receptors displayed by the drug; refuting the possibility that it is due to 5-HT1B activation, it was also not counteracted by isamoltane. (-)-OSU61612 did not display the profile of an anxiogenic or anxiolytic drug in the EPM but caused a general reduction in activity that is well in line with the previous finding that it reduces exploratory behavior of non-habituated animals. In line with the observations in males, (-)-OSU61612 reduced estrus cycle-related aggression in female Wistar rats, a tentative animal model of premenstrual dysphoria. By stabilizing dopaminergic transmission, (-)-OSU61612 may prove useful as a well-tolerated treatment of various forms of aggression and irritability.

The Effects of the Monoamine Stabilizer (-)-OSU6162 on Binge-Like Eating and Cue-Controlled Food-Seeking Behavior in Rats.

2018-02-01

Binge-eating disorder (BED) is characterized by recurring episodes of excessive consumption of palatable food and an increased sensitivity to food cues. Patients with BED display an addiction-like symptomatology and the dopamine system might be a potential treatment target. The clinically safe monoamine stabilizer (-)-OSU6162 (OSU6162) restores dopaminergic dysfunction in long-term alcohol-drinking rats and shows promise as a novel treatment for alcohol use disorder. Here, the effects of OSU6162 on consummatory (binge-like eating) and appetitive (cue-controlled seeking) behavior motivated by chocolate-flavored sucrose pellets were evaluated in non-food-restricted male Lister Hooded rats. OSU6162 significantly reduced binge-like intake of chocolate-flavored sucrose pellets without affecting prior chow intake. Furthermore, OSU6162 significantly reduced the cue-controlled seeking of chocolate-flavored sucrose pellets under a second-order schedule of reinforcement before, but not after, the delivery and ingestion of reward, indicating a selective effect on incentive motivational processes. In contrast, the dopamine D2/D3 receptor antagonist raclopride reduced the seeking of chocolate-flavored sucrose pellets both pre- and post reward ingestion and also reduced responding under simpler schedules of seeking behavior. The D1/5 receptor antagonist SCH23390 had no effect on instrumental behavior under any reinforcement schedule tested. Finally, local administration of OSU6162 into the nucleus accumbens core, but not dorsolateral striatum, selectively reduced cue-controlled sucrose seeking. In conclusion, the present results show that OSU6162 reduces binge-like eating behavior and attenuates the impact of cues on seeking of palatable food. This indicates that OSU6162 might serve as a novel BED medication.

Optometric supply and demand in Australia: 2011-2036.

PubMed

Healy, Ernest; Kiely, Patricia M; Arunachalam, Dharma

2015-05-01

The effective size of the optometric workforce is dependent on graduate numbers, retention rates and immigration and is influenced by age, gender and working hours of optometrists. This paper presents modelling results of the relationship between the projected Australian optometric workforce and projected demand for optometric services for the period 2011 to 2036. Nine hypothetical optometric supply-side and demand-side scenarios are presented. Data from the Australian Bureau of Statistics on age and gender of people listing optometry as their major qualification in the 2011 census were projected over a 25-year period, accounting for factors such as concordance with Health Workforce Australia figures for registered optometrists in Australia in 2011, ageing, attrition, hours worked, new graduates and immigration. Data were compared to the numbers of optometrists calculated as necessary to meet the demand for services of the Australian population to 2036 using nine different scenarios. It was estimated that there would be a surplus of over 1,200 equivalent full-time optometrists (EFTO) in 2036 for the highest service demand scenario of 13.8 million Medicare services, where 21 hours of a 38-hour week per EFTO were allowed for the provision of optometric services under Medicare. Substantial surpluses were predicted in all states and territories except Queensland, Tasmania and the Northern Territory where predicted supply was within six EFTO of predicted demand. Projections using current weightings for mortality, attrition, proportion of optometrists in active practice, working hours, immigration, new graduates and 21 hours per EFTO per week available for Medicare services indicate that in 2036, there will be excess optometrists in relation to projected demand for services, if service utilisation is maintained at current levels or increased by 10 or 20 per cent. Substantially greater excesses result if each EFTO has 28 or 35 hours per week available for Medicare services. © 2015 The Authors. Clinical and Experimental Optometry © 2015 Optometry Australia.

In Vitro and In Vivo Analysis of Indocyanine Green-Labeled Panitumumab for Optical Imaging—A Cautionary Tale

PubMed Central

2015-01-01

Indocyanine green (IC-Green), the only FDA approved near-infrared (NIR) fluorophore for clinical use, is attractive to researchers for the development of targeted optical imaging agents by modification of its structure and conjugation to monoclonal antibodies (mAbs) or their fragments. IC-Green derivative, ICG-sulfo-OSu (ICG-sOSu), is frequently used for antibody conjugation. However, ICG-sOSu is amphiphilic and readily facilitates aggregation of mAbs that is not easily separable from the desired immunoconjugates. Complications originating from this behavior are frequently overlooked by researchers. This study examined detailed chemical and biological characteristics of an ICG-sOSu-labeled mAb, panitumumab, and provided a clinically applicable strategy to deliver a pure conjugation product. Size-exclusion high-performance liquid chromatography (SE-HPLC) analysis of conjugation reactions, performed at molar reaction ratios of ICG-sOSu: mAb of 5, 10, or 20, resulted in isolable desired ICG-sOSu-panitumumab conjugation product in 72%, 53%, and 19% yields, respectively, with the remainder consisting of high molecular weight aggregates (>150 kDa) 14%, 30%, and 51%, respectively. The HPLC-purified ICG-sOSu-panitumumab products were analyzed by native and SDS polyacrylamide gel electrophoresis (PAGE) followed by optical imaging. Results indicated that the interaction between ICG-sOSu and panitumumab was due to both covalent and noncovalent binding of the ICG-sOSu to the protein. Noncovalently bound dye in the ICG-sOSu-panitumumab conjugate products was removed by extraction with ethyl acetate to further purify the HPLC-isolated conjugation products. With conserved immunoreactivity, excellent target-specific uptake of the doubly purified bioconjugates was observed with minimal liver retention in athymic nude mice bearing HER1-expressing tumor xenografts. In summary, the preparation of well-defined bioconjugate products labeled with commercial ICG-sOSu dye is not a simple process and control of the conjugation reaction ratio and conditions is crucial. Furthermore, absolute purification and characterization of the products is necessitated prior to in vivo optical imaging. Use of validated and characterized dye conjugate products should facilitate the development of clinically viable and reproducible IC-Green derivative and other NIR dye mAb conjugates for optical imaging applications.

The soil matrix can sequester arsenic (As) and reduces its exposure by soil ingestion. In vivo dosing studies and in vitro gastrointestinal (IVG) methods have been used to predict relative bioavailable (RBA) As. Originally, the Ohio State University (OSU-IVG) method predicted RBA As for soils exclusively from mining and smelting sites with a median of 5,636 mg As kg-1. The objectives of the current study were to (i) evaluate the ability of the OSU-IVG method to predict RBA As for As contaminated soils with a wider range of As content and As contaminant sources, and (ii) evaluate a modified extraction procedure's ability to improve prediction of RBA As. In vitro bioaccessible (IVBA) by OSU-IVG and California Bioaccessibility Method (CAB) methods, RBA As, speciation, and properties of 33 As contaminated soils were determined. Total As ranged from 162 to 12,483 mg kg-1 with a median of 731 mg kg-1. RBA As ranged from 1.30 to 60.0% and OSU-IVG IVBA As ranged from 0.80 to 52.3%. Arsenic speciation was predominantly As(V) adsorbed to hydrous ferric oxide (HFO) or iron (Fe), manganese (Mn), and aluminum (Al) oxides. The OSU-IVG often extracted significantly less As in vitro than in vivo RBA As, in particularly for soils from historical gold mining. The CAB method, which is a modified OSU-IVG method extracted more As than OSU-IVG for most soils, resulting in a more accurate predictor than OSU-IVG, especially for low to moderately contaminated soils (<1,500 mg As

The History of Ethics and Professionalism within Optometry in the United States of America 1898-2015, Part 1.

The history surrounding the development of codes of ethics and other official statements of desired professional conduct adopted by the American Optometric Association (AOA) reveals the struggle optometry faced in the United States ofAmerica (USA) in establishing itself as a leading primary health care profession. Information regarding the events and documents reported in this paper were obtained through research of the historical literature and archival material held in The Archives & Museum of Optometry at the American Optometric Association's headquarters at 243 N. Lindbergh Boulevard, St. Louis, MO; through current Association documents; and from discussions with those participating in the drafting of the more recent updates to the Association's ethical statements; codes, oaths, standards, and resolutions. This writing is an update to an earlier paper by the author, The history of ethics in the American Optometric Association 1898-1994. J Am Optom Assoc 1994; 65:427-444, which was written to celebrate the 50th anniversary of the then current Code of Ethics of the AOA. An additional purpose of this present writing is to help the reader understand, from a historical perspective, some of the driving forces and imperatives for the advancement of optometry's professional stature. Forces outside as well as within the profession were found to have influenced the drafting and redrafting of the official ethical and professional conduct statements meant to guide the professional behavior of the membership of the AOA. Ethical codes and other statements of desired conduct have been essential to the establishment of the profession of optometry. As optometry has grown and matured as a provider of primary eye and vision care services, so have its ethical emphases. To further understand the ethical and legal challenges for optometry as it worked to establish itself as a reputable profession, it is suggested the reader investigate in more detail the information provided in the references. Any views expressed in this paper are those of the author and do not necessarily reflect the views of the American Optometric Association.

Breaking down barriers to eye care for Indigenous people: a new scheme for delivery of eye care in Victoria.

2015-09-01

This report describes the implementation of and outcomes from a new spectacle subsidy scheme and de-centralised care options for Aboriginal and Torres Strait Islander peoples in Victoria, Australia. The Victorian Aboriginal Spectacle Subsidy Scheme (VASSS) commenced in 2010, as an additional subsidy to the long-established Victorian Eyecare Service (VES). The Victorian Aboriginal Spectacle Subsidy Scheme aimed to improve access to and uptake of affordable spectacles and eye examinations by Indigenous Victorians. The scheme is overseen by a committee convened by the Victorian Government's Department of Health and Human Services and includes eye-health stakeholders from the Aboriginal community and government, not-for-profit, university and Aboriginal communities. Key features of the Victorian Aboriginal Spectacle Subsidy Scheme include reduced and certain patient co-payments of $10, expanded spectacle frame range, broadened eligibility and community participation in service design and implementation. We describe the services implemented by the Australian College of Optometry (ACO) in Victoria and their impact on access to eye-care services. In 2014, optometric services were available at 36 service sites across Victoria, including 21 Aboriginal Health Services (AHS) sites. Patient services have increased from 400 services per year in 2009, to 1,800 services provided in 2014. During the first three years of the Victorian Aboriginal Spectacle Subsidy Scheme program (2010 to 2013), 4,200 pairs of glasses (1,400 pairs per year) were provided. Further funding to 2016/17 will lift the number of glasses to be delivered to 6,600 pairs (1,650 per year). This compares to population projected needs of 2,400 pairs per year. Overcoming the barriers to using eye-care services by Indigenous people can be difficult and resource intensive; however the Victorian Aboriginal Spectacle Subsidy Scheme provides an example of positive outcomes achieved through carefully designed and targeted approaches that engender sector and stakeholder support. Sustained support for the Victorian Aboriginal Spectacle Subsidy Scheme at a level that meets population needs is an ongoing challenge. © 2015 The Authors.

Report on the status of vision care in Israel.

PubMed

Levinson, A; Scheiman, M

1981-07-01

Recognition of optometry in Israel has not been achieved due to various factors: the lack of recognition by the Ministry of Health in proposing a law of optometry to the Knesset (Parliament); the opposition of organized ophthalmology; the internal conflict between the various associations of opticians and optometrists within the country which lead to a lack of unification for propagation of a law of optometry; the absence of an academic institution of learning in optometry. The establishment of the Optometric Centre by the American Friends of Israel Optometry has instituted low vision clinics and post-graduate courses which have helped to advance optometry. Optometry must become organized in order to apply pressure on the Ministry of Health in order to recognize optometry as an independent profession. There is a need for the establishment of operating courses to equalize the standard of eye-care in the profession, and for the founding of an academic school of optometry to maintain a constant supply of qualified optometrists.

To compare (a). the clinical effectiveness and (b). cost effectiveness of the two models in screening for diabetic retinopathy. (a). Retrospective analysis of referral diagnoses of each screening model in their first respective years of operation and an audit of screen positive patients and a sample of screen negatives referred to the hospital eye service from both screening programmes. (b). Cost effectiveness study. (1). A total of 1643 patients screened in the community and in digital photography clinics; (2). 109 consecutive patients referred to the Diabetic Eye Clinic through the two existing models of diabetic retinopathy screening; (3). 55 screen negative patients from the optometry model; (4). 68 screen negative patients audited from the digital photography model. The compliance rate was 45% for optometry (O) vs 50% for the digital imaging system (I). Background retinopathy was recorded at screening in 22% (O) vs 17% (I) (P=0.03) and maculopathy in 3.8% (O) vs 1.7% (I) (P=0.02). Hospital referral rates were 3.8% (O) vs 4.2% (I) Sensitivity (75% for optometry, 80% for digital photography) and specificity (98% for optometry and digital photography) were similar in both models. The cost of screening each patient was pound 23.99 (O) vs pound 29.29 (I). The cost effectiveness was pound 832 (O) vs pound 853(I) in the first year. The imaging system was not always able to detect early retinopathy and maculopathy; it was equally specific in identifying sight-threatening disease. Cost effectiveness was poor in both models, in their first operational year largely as a result of poor compliance rates in the newly introduced screening programme. Cost effectiveness of the imaging model should further improve with falling costs of imaging systems. Until then, it is essential to continue any existing well-coordinated optometry model.

Optometry is only provided at tertiary level in two institutions in Ghana, with an average of 50 students graduating each year for a population of approximately 24.6 million. No information on the demography of optometry students and factors that influence their choice of optometry as a career and institution of learning is available. This information is important as it will assist optometry institutions to formulate effective student recruitment strategies. To assess the demographic characteristics of Ghanaian optometry students, the factors that influence their selection of optometry as a career and institution of learning. We conducted a cross sectional study among Ghanaian optometry students using a structured questionnaire to collect data on the demographic characteristics and factors that might influence their choice of optometry as a career as well as choice of institution of learning. Two hundred and eighty students from the two optometry training institutions in Ghana; University of Cape Coast (48.2%) and Kwame Nkrumah University of Science and Technology (51.8%) responded to the questionnaire. Their ages ranged from 17 to 28 years with most being males (72.5%), and the majority (79%) being from urban areas. The main factors that influenced their career choice were job availability after graduation (90%) and desire to help other people (89.2%). Factors that influenced their institution choice were preference for an institution (36.8%) and proximity to home (24.4%). In the absence of adequate optometry jobs in the public health sector, women will remain marginalised specifically those in rural areas. This marginalisation is however, a reflection of a broader societal disadvantage for women. Greater effort needs to be made to recruit high school students from rural areas to study optometry and more institutions need to provide optometry instruction throughout the country.

GPA/GPSA/OSU-Okmulgee natural gas compression technician training program

DOE Office of Scientific and Technical Information (OSTI.GOV)

Doede, S.

Approximately one year ago, OSU-Okmulgee and the Gas Processors Association began discussions about the possibility of developing a natural Gas Technician Training Program for GPA members. Following a presentation to the Membership and Services Committee, Chairman John Ehlers solicited and obtained the approval of the GPA Executive Committee to sponsor the program. Participation in the program was also made available to GPSA members. The purpose of the program is to upgrade the technical competency and professional level of incoming natural gas compression technicians. It educates students to analytically diagnose, service and maintain gas compression equipment and systems using industry recommendedmore » procedures, special tools and service information. It also provides course content, which will enable successful graduates to advance in position after additional experience, and to understand new systems, technologies and components as they are introduced. The two-year Associate-In-Applied Science Degree program includes six successive college semesters. Nearly one-half of the time is designated for technical/academic education at Oklahoma State University-Okmulgee with the balance of time allocated for on-the-job internship experiences at sponsoring GPA/GPSA members. Each block of technical education and general education course work is followed by an immediate work experience time period designated to reinforce the technical and general education. These time periods are approximately seven and one-half weeks in length each. It is essential for the success of the students and the program that the students' education at OSU-Okmulgee and work experiences at GPA/GPSA member facilities be closely aligned for maximum student learning and retention. In addition to technical classes on gas compression equipment and components, the courses offered in math, speech, technical writing, psychology and ethics for example, prepare students to be able to communicate well, get along with others and be responsible and productive employees.« less

Summary Drug resistance and associated immune deregulation limit use of current therapies in chronic lymphocytic leukaemia (CLL), thus warranting alternative therapy development. Herein we demonstrate that OSU-DY7, a novel D-tyrosinol derivative targeting p38 mitogen-activated protein kinase (MAPK), mediates cytotoxicity in lymphocytic cell lines representing CLL (MEC-1), acute lymphoblastic leukaemia (697 cells), Burkitt lymphoma (Raji and Ramos) and primary B cells from CLL patients in a dose- and time-dependent manner. The OSU-DY7-induced cytotoxicity is dependent on caspase activation, as evidenced by induction of caspase-3 activation and poly (ADP-ribose) polymerase (PARP) cleavage and rescue of cytotoxicity by Z-VAD-FMK. Interestingly, OSU-DY7-induced cytotoxicity is mediated through activation of p38 MAPK, as evidenced by increased phosphorylation of p38 MAPK and downstream target protein MAPKAPK2. Pretreatment of B-CLL cells with SB202190, a specific p38 MAPK inhibitor, results in decreased MAPKAPK2 protein level with concomitant rescue of the cells from OSU-DY7-mediated cytotoxicity. Furthermore, OSU-DY7-induced cytotoxicity is associated with down regulation of p38 MAPK target BIRC5, that is rescued at protein and mRNA levels by SB202190. This study provides evidence for a role of OSU-DY7 in p38 MAPK activation and BIRC5 down regulation associated with apoptosis in B lymphocytic cells, thus warranting development of this alternative therapy for lymphoid malignancies.

Optometry: a discipline of knowledge

NASA Astrophysics Data System (ADS)

Kedzia, Boleslaw

1998-10-01

Optometry is a branch of science whose roots are in optics development as well as in physiology development. Among Polish scholars, whose names are firmly engraved in the history of optometry, two names should be mentioned first, they are Witelo (1237 - 1290) and Majer (1808 - 1899). Contemporary optometry began around the turn of the 19th and 20th century in the United States of America where some states erected legal regulations for those opticians who were performing refractions. Since 1993 optometry has been defined by the World Council of Optometry as a health care profession which is autonomous, educated and regulated (licensed/registered). Nevertheless, the question arises: Is optometry a separate part of science or is it only a set of practical procedures useful in vision care? In other words: does optometry have a system of definitions, laws and hypothesis with such logical interrelations that all less general statements may be derived from the most general? Even at this moment the system is not fully developed, yet we can say that optometry is a set of statements important and enough proved to be taught at the university level, being a category by itself and being sufficiently rich to be a subject for teaching as separate discipline.

A case study in the politics of free-market health care.

PubMed

Begun, J W; Lippincott, R C

1982-01-01

Historically, most health occupations have developed legal and ethical restrictions on price advertising and other characteristics of "commercial" practice. Many of these regulations recently have come under critical scrutiny, on the grounds that they inhibit free-market health care delivery, thus keeping prices high, and productivity and innovation low. To help inform current health policy deliberations, we analyze the political history of anticompetitive regulations in one health occupation, optometry. Restrictions on commercial practice arose as a result of professional optometry's purge of commercial elements in the 1930s. Optometry's success in achieving commercial-practice restrictions at the state level was determined by the economic structure of the ophthalmic goods and services industry in each state in the 1930s, and by the political resources and organization of the competing interest groups. Efforts to deregulate health occupations will precipate political conflict to the extent that economic interests are threatened. Opposition to deregulation will be based overtly on the grounds that quality of care will deteriorate, and a significant political investment by proponents of free-market health care will be required to overcome such opposition.

[Effects of physics on development of optometry in the United States from the late 19th to the mid 20th century].

PubMed

Kim, Dal-Young

2014-08-01

In this paper, it was studied how physics affected development of optometry in the United States, from aspects of formation and academization of optometry. It was also revealed that history of optometry was analogous to history of engineering. Optics in the 19th century was divided into electromagnetic study of light and visual optics. Development of the visual optics promoted professionalization of ophthalmology that had already started in the 18th century. The visual optics also stimulated formation of optometry and optometrists body in the late 19th century of the United States. The American optometrists body were originated from opticians who had studied visual optics. Publication of several English academic textbooks on visual optics induced appearance of educated opticians (and jewelers). They acquired a right to do the eye examination in the early 20th century after C. F. Prentice's trial in 1897, evolving into optometrists. The opticians could be considered as craftsmen, and they were divided into (dispensing) opticians and optometrists. Such history of American optometrists body is analogous to that of engineers body in the viewpoints of craftsmen origin and separation from craftsmen. Engineers were also originated from educated craftsmen, but were separated from craftsmen when engineering was built up. Education system and academization of optometry was strongly influenced by physics, too. When college education of optometry started at American universities, it was not belonged to medical school but to physics department. Physics and optics were of great importance in curriculum, and early faculty members were mostly physicists. Optometry was academized in the 1920s by the college education, standardization of curriculum, and formation of the American Academy of Optometry. This is also analogous to history of engineering, which was academized by natural sciences, especially by mathematics and physics. The reason why optometry was academized not by medicine but by physics is because ophthalmologists did not have conciliatory attitudes to optometry education. Optometry became independent of physics from the 1930s to the 1940s. Optometric researches concentrated on binocular vision that is not included to discipline of physics, and faculty members who majored in optometry increased, so that optometry departments and graduate schools were established around 1940. Such independence from natural sciences after academization also resembles history of engineering. On the contrary, history of optometry was different from history of ophthalmology in several aspects. Ophthalmology had already been formed in the 18th century before development of visual optics, and was not academized by visual optics. Ophthalmologists body were not originated from craftsmen, and were not separated from craftsmen. History of optometry in the United States from the late 19th to the mid 20th century is analogous to history of engineering rather than history of medicine, though optometry is a medical discipline.

Ensuring standards for the extended role of optometry.

PubMed

Jarvis, Ian; Ker, Jean

2014-06-01

In optometry, as in other health professions, such as pharmacy and nursing, there has been an expansion in the role of the optometrist in primary eye care, taking on aspects of care such as prescribing, which was traditionally undertaken by general practitioners. In optometry, this extended role involves monitoring eye conditions that do not require treatment or monitoring in secondary care, roles that were traditionally referred on. However, any extended role requires educational support. The development of a national educational programme can prevent any duplication of effort and provide a system of disseminating support to practitioners, who often work in isolation. The National Education Programme was developed and supported by the National Health Service (NHS) Education for Scotland (NES). This a national body responsible for supporting NHS services in Scotland, by developing and delivering education and training for those who work in NHS Scotland. Optometrists were given educational support in three main stages: simulation of component skills; safe learning in a simulated health care context; and support for the transfer of those skills to practice, including the use of mentoring via e-mail. The evaluation of this three-stage process has been positive. To further develop any expanded role in health care practice, safe guidelines for practice are required. Simulation can provide support at the start of this process in setting standards. However, mentorship in the practice area, as reported in this study, was required to embed newly acquired skills. © 2014 John Wiley & Sons Ltd.

This paper presents results from the inaugural Scope of Practice Survey of Optometry Australia members conducted in October 2015. The survey gathered information related to confidence in detecting and diagnosing key ocular conditions, grading diabetic retinopathy, prescribing scheduled medicines, access to equipment, confidence using equipment, incidence of patients requiring therapeutic management, referral practices and services provided. The survey was developed, piloted, modified and administered to members of Optometry Australia (excluding student and retired members), who had a current email address. Results were collated and analysed using Microsoft Excel. Of the 587 optometrists in clinical practice who responded, 254 (43 per cent) had therapeutic endorsement of registration. The majority of respondents practised in a major city or surrounding suburbs (63 per cent). Independent practice was the most frequently cited practice type (58 per cent). The estimated average number of patients seen in a week was 48; there was a steady decrease in the number of patients per week with increasing age, from 53 for optometrists in their 20s to 27 for optometrists aged over 70. There was very high confidence (over 93 per cent) in ability to grade diabetic retinopathy and diagnose a range of ocular conditions. Confidence in performance of more advanced techniques was higher for endorsed than non-endorsed optometrists. Approximately 12 per cent of patients required a Schedule 4 therapeutic prescription. The most frequently recommended over-the-counter medications were for dry eye for both endorsed and non-endorsed optometrists. The most frequently prescribed Schedule 4 medications were anti-inflammatories. The most challenging conditions to prescribe for were glaucoma, microbial keratitis and uveitis. Approximately one in six therapeutically endorsed optometrists reported unexpected side effects of medications they had prescribed. Information from the survey will guide Optometry Australia in the design of continuing professional development programs and other materials. © 2017 Optometry Australia.

An update on the characteristics of patients attending the Kooyong Low Vision Clinic.

Since 1972, the Australian College of Optometry has worked in partnership with Vision Australia to provide multidisciplinary low-vision care at the Kooyong Low Vision Clinic. In 1999, Wolffsohn and Cochrane reported on the demographic characteristics of patients attending Kooyong. Sixteen years on, the aim of this study is to review the demographics of the Kooyong patient cohort and prescribing patterns. Records of all new patients (n = 155) attending the Kooyong Low Vision Clinic for optometry services between April and September 2012 were retrospectively reviewed. Median age was 84.3 years (range 7.7 to 98.1 years) with 59 per cent female. The majority of patients presented with late-onset degenerative pathology, 49 per cent with a primary diagnosis of age-related macular degeneration. Many (47.1 per cent) lived with their families. Mean distance visual acuity was 0.57 ± 0.47 logMAR or approximately 6/24. The median spectacle-corrected near visual acuity was N8 (range N3 to worse than N80). Fifty patients (32.3 per cent) were prescribed new spectacles, 51 (32.9 per cent) low vision aids and five (8.3 per cent) were prescribed electronic magnification devices. Almost two-thirds (63.9 per cent) were referred for occupational therapy management and 12.3 per cent for orientation and mobility services. The profile of patients presenting for low-vision services at Kooyong is broadly similar to that identified in 1999. Outcomes appear to be similar, aside from an expected increase in electronic devices and technological solutions; however, the nature of services is changing, as treatments for ocular diseases advance and assistive technology develops and becomes more accessible. Alongside the aging population and age-related ocular disease being the predominant cause of low vision in Australia, the health-funding landscape is becoming more restrictive. The challenge for the future will be to provide timely, high-quality care in an economically efficient model. © 2016 Optometry Australia.

Electronic cigarettes (e-cigarettes) have grown in popularity, especially among youth and young adults. Although e-cigarettes were originally intended to vaporize a liquid mixture containing nicotine, there appears to be an increasing trend in other substance use in e-cigarettes (OSUE). Cross-sectional data from 1542 undergraduate college student e-cigarette users from a large Midwestern university were collected via online survey to assess prevalence of e-cigarette use, reasons for use, perceived harm, and prevalence and predictors of OSUE. Nearly 7% (6.94%) reported using an e-cigarette to vaporize and inhale a substance other than nicotine. Current tobacco cigarette smokers were significantly more likely to report OSUE (51.0%) as compared with never (33.7%) and former (15.4%) smokers. Among respondents reporting OSUE, the primary reason for e-cigarette use was "safer than cigarettes" (21.7%), followed by "experimentation" (18.9%) and "friends use" (17.0%). Most (77.9%) reported using cannabis or some derivative of cannabis in an e-cigarette. Binomial logistic regression found that women were less likely to report OSUE by a factor of 0.60, former tobacco cigarette smokers as compared with never smokers were more likely to report OSUE by a factor of 1.87, and e-cigarette users who reported using e-cigarettes for "cool or trendy" reasons were more likely to report OSUE by a factor of 2.89. Little is known regarding the health effects of cannabis and cannabis derivatives delivered through e-cigarettes. Concern may also be warranted regarding the potential dangers of this young population using substances more dangerous than cannabis in e-cigarettes. Knowledge is limited regarding the public health impact of vaping cannabis or other illicit substances among college student populations. This study stresses the need for continued research regarding the vaping of cannabis and other illicit substances among college students.

Optometry in Portugal: a historical perspective

The establishment and development of optometry in Portugal resulted from the committed work of many individuals and institutions. These efforts have had good results in terms of raising the public's awareness of the major role played by optometrists in primary eye care. Back in the late 80's higher education in optometry was started. Ten years ago the results of scientific research on the topic first became available and are now also contributing to the success of optometry in Portugal. In regard to the optometry profession, specific regulations are to be discussed in the national parliament. The Associação de Profissionais Licenciados de Optometria (APLO), as the professional organization representing optometrists in Portugal, has been critically important in this process. This article will present an overview of the history of optometry in Portugal, of change in the foreseeable future and of the APLO's experience and activities.

E. LeRoy Ryer and Elmer E. Hotaling were very prominent optometrists of the first half of the twentieth century and made numerous contributions to the profession. They were among the early pioneers of professional optometry practice. They published many articles in optometry journals, and did work in instrument design. They were charter members of the American Academy of Optometry in 1922, Ryer having suggested such an organization in 1905. In the first decade of the twentieth century, they were briefly faculty members in a two-year optometry school, an unusual length of study for the time. This paper presents brief biographical sketches of each, along with discussion of the two books they coauthored, Optometric Procedure and Ophthalmometry. The former book contained much of their views on how optometry should be practiced.

This study was designed to determine the use of optometrists with the Veterans Health Administration hospital system and to develop accurate statistics regarding the number and type of services these doctors provide. The findings help describe their responsibilities in the treatment and management of ocular diseases and their use of diagnostic and therapeutic drugs. The study also investigated what, if any, role optometrists play beyond care in the education and research practices of the hospital. A descriptive analysis was conducted through the use of surveys and interviews of department chiefs or medical directors. A survey was sent out to 149 Veterans Affairs (VA) Hospitals, located using the VA facility locator Web site. Data were tabulated, aggregated, and analyzed. A response rate of 81% was achieved (122 surveys returned), 98% of which (120 facilities) provide eye services to their patients in either an outpatient or inpatient capacity. One hundred seventeen (98%) of these had optometrists affiliated with their facility. These optometrists were responsible for providing a range of services, prescribing the use of diagnostic or therapeutic drugs, and participating in educational training of other health personnel. Optometry has developed a strong partnership with the Veterans Health Administration, and act as an integral part of its hospital services. The VA has developed a workforce mix that should serve as a model for managed care organizations.

Gupta, Vivek K; Gupta, Veer B

2016-11-15

Rapid advances in ocular diagnostic approaches and emerging links of pathological changes in the eye with systemic disorders have widened the scope of optometry as the front line of eye health care. Expanding professional requirements stipulate that optometry students get a meticulous training in relevant information and communication technologies (ICT) and various bioinformatics and health informatics software to meet current and future challenges. Greater incorporation of ICT approaches in optometry education can facilitate increased student engagement in shared learning experiences and improve collaborative learning. This, in turn, will enable students to participate in and prepare for the complex real-world situations. A judicious use of ICTs by teachers in learning endeavors can help students develop innovative patterns of thinking to be a successful optometry professional. ICT-facilitated learning enables students and professionals to carry out their own research and take initiatives and thus shifts the equilibrium towards self-education. It is important that optometry and allied vision science schools adapt to the changing professional requirements with pedagogical evolution and react appropriately to provide the best educational experience for the students and teachers. This review aims to highlight the scope of ICT applications in optometry education and professional development drawing from similar experiences in other disciplines. Further, while enhanced use of ICT in optometry has the potential to create opportunities for transformative learning experiences, many schools use it merely to reinforce conventional teaching practices. Tremendous developments in ICT should allow educators to consider using ICT tools to enhance communication as well as providing a novel, richer, and more meaningful medium for the comprehensive knowledge construction in optometry and allied health disciplines.

Screening and identifying diabetes in optometric practice: a prospective study.

PubMed

Howse, Jennifer H; Jones, Steve; Hungin, A Pali S

2011-07-01

Unconventional settings, outside general medical practice, are an underutilised resource in the attempt to identify the large numbers of people with undiagnosed diabetes worldwide. The study investigated the feasibility of using optometry practices (opticians) as a setting for a diabetes screening service. Adults attending high street optometry practices in northern England who self-reported at least one risk factor for diabetes were offered a random capillary blood glucose (rCBG) test. Those with raised rCBG levels were asked to visit their GP for further investigations. Of 1909 adults attending practices for sight tests, 1303 (68.2%) reported risk factors for diabetes, of whom 1002 (76.9%) had rCBG measurements taken. Of these, 318 (31.7%) were found to have a rCBG level of ≥6.1 mmol/l, a level where further investigations are recommended by Diabetes UK; 1.6% of previously undiagnosed individuals were diagnosed with diabetes or pre-diabetes as a result of the service. Refining the number of risk factors for inclusion would have reduced those requiring screening by half and still have identified nearly 70% of the new cases of diabetes and pre-diabetes. Screening in optometric practices provides an efficient opportunity to screen at-risk individuals who do not present to conventional medical services, and is acceptable and appropriate. Optometrists represent a skilled worldwide resource that could provide a screening service. This service could be transferable to other settings.

Effects of (-)-OSU6162 and ACR16 on motor activity in rats, indicating a unique mechanism of dopaminergic stabilization.

PubMed

Rung, Johan P; Rung, Emilia; Helgeson, Lisa; Johansson, Anette M; Svensson, Kjell; Carlsson, Arvid; Carlsson, Maria L

2008-06-01

Dopaminergic stabilizers can be defined as drugs that stimulate or inhibit dopaminergic signalling depending on the dopaminergic tone. (-)-OSU6162 and ACR16 appear to possess such a profile. They have been proposed to act as partial dopamine receptor agonists or as antagonists with preferential action on dopaminergic autoreceptors. Previous studies have shown either stimulation or inhibition of behaviour in response to (-)-OSU6162 and ACR16, which has been suggested to reflect their dual effects on dopaminergic signalling. The aims of the present work are to (1) examine the relation between behavioural response to these drugs and activity baseline, and (2) test the suggested mechanisms of action by means of close comparisons with the known partial D2-receptor agonists (-)-3-PPP and aripiprazole, and the D2 autoreceptor preferring antagonist amisulpride with respect to effects on behaviour. From the results of these experiments it can be concluded that: (1) The direction of the response to (-)-OSU6162 and ACR16 is dependent on activity baseline, which in turn, under physiological conditions, is determined primarily by test arena size of and degree of habituation to the environment. (2) The effects of (-)-OSU6162 and ACR16 cannot be explained on the basis of either partial dopamine receptor agonism or preferential dopamine autoreceptor antagonism. Nevertheless, the current data suggest at least two different D2-receptor-associated targets which mediate opposite effects on activity. This result fits in with a mechanism proposed from a recent in vitro study, according to which (-)-OSU6162 has a dual action on dopamine D2 receptors, (a) an allosteric effect causing an enhanced response to dopamine, and (b) the previously proposed orthosteric effect antagonizing the action of dopamine.

The Ohio State University (OSU) group contributed to the deliverables of the JET Collaboration three major products: 1. The code package iEBE-VISHNU for modeling the dynamical evolution of the soft medium created in relativistic heavy-ion collisions, from its creation all the way to final freeze-out using a hybrid approach that interfaces a free-streaming partonic pre-equilbrium stage with a (2+1)-dimensional viscous relativistic fluid dynamical stage for the quark-gluon plasma (QGP) phase and the microscopic hadron cascade UrQMD for the hadronic rescattering and freeze-out stage. Except for UrQMD, all dynamical evolution components and interfaces were developed at OSU and tested and implementedmore » in collaboration with the Duke University group. 2. An electromagnetic radiation module for the calculation of thermal photon emission from the QGP and hadron resonance gas stages of a heavy-ion collision, with emission rates that have been corrected for viscous effects in the expanding medium consistent with the bulk evolution. The electromagnetic radiation module was developed under OSU leadership in collaboration with the McGill group and has been integrated in the iEBE-VISHNU code package. 3. An interface between the Monte Carlo jet shower evolution and hadronization codes developed by the Wayne State University (WSU), McGill and Texas A&M groups and the iEBE-VISHNU bulk evolution code, for performing jet quenching and jet shape modification studies in a realistically modeled evolving medium that was tuned to measured soft hadron data. Building on work performed at OSU for the theoretical framework used to describe the interaction of jets with the medium, initial work on the jet shower Monte Carlo was started at OSU and moved to WSU when OSU Visiting Assistant Professor Abhijit Majumder accepted a tenure track faculty position at WSU in September 2011. The jet-hydro interface was developed at OSU and WSU and tested and implemented in collaboration with the McGill, Texas A&M, and LBNL groups.« less

Geopotential models in the Australian region

Kearsley, A. H. W.; Holloway, R. D.

1989-01-01

The ability of three high-order geopotential models (OSU81, GPM2 and OSU86E) to recover the gravity anomaly field (delta g) in the Australian region was tested. The region was divided into 2 x 2 deg blocks, and the mean and rms of the residual gravity (delta g measured - delta g modeled) was found to estimate the fit of the model to the point gravity data. The results showed that OSU81 and GPM2 performed similarly, recovering the delta g with a mean value of less than plus or minus 5 mGal in 63 and 70 percent of the blocks, respectively. However, both these models achieved a fit of worse that was plus or minus 13 mGal in 6 to 7 percent of cases. These were in areas either on or near the coast, or in the Central Australian region, inferring that for a precise geoid slope determination in these regions, a detailed analysis of delta g in region is needed. On the other hand, OSU86E produced a very good result, having a mean fit of less than plus or minus 5 mGal in 80 percent of the blocks, and worse than plus or minus 13 mGal in only 1 percent of cases. The rms values for this model were also improved over the other two models, indicating that for applications requiring highest precision, the preferred model is OSU86E.

Teaching optics in a multi-disciplinary curriculum: experience from optometry programs

NASA Astrophysics Data System (ADS)

Lakshminarayanan, Vasudevan

2007-06-01

The Optometry program in Schools and Colleges of Optometry leads to a Doctor of Optometry (OD) degree in north America and is usually a post-baccalaureate course of study of four years duration. Historically Optometry developed out of Physics and/or applied optics programs. Optics, and more specifically, geometric optics and it's applications to the human eye plays a significant role in the education of an optometrist. In addition, optometrists are trained in physical optics as well as in radiometry/photometry. Considering the fact that most optometry students come to the program with a biological sciences background implies that educating these students require elucidation of "real-world" applications and clinical relevance to hold their interest. Even though the trend in optometric education in the past few years is to put more emphasis on biological sciences due to the increased scope of practice of the optometrist, optics still continues to play a major role in the training and career of an optometrist, especially with the advent of new technologies in treating low vision, measurement and correction of aberrations of the eye, etc.

To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026. Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take action. Copyright © 2014 Spanish General Council of Optometry. Published by Elsevier Espana. All rights reserved.

Optometry is affected by political, social and economic forces. Optometric leaders must understand that the issues of health care reform, education reform and economic reform can only be met through cooperation of all professionals, educational associations, as well as individual institutions. With good management, innovative use of available funds, and development of personnel, optometry can overcome contracted revenues and prosper through this decade. However, there is no doubt that educational reform is at the doorstep of the health care professions. Optometry must strive to face its challenges now and into the remaining years of this decade.

2015-01-01

With the development of photoelectric technology and single-chip microcomputer technology, objective optometry, also known as automatic optometry, is becoming precise. This paper proposed a presbyopia optometry method based on diopter regulation and Charge Couple Device (CCD) imaging technology and, in the meantime, designed a light path that could measure the system. This method projects a test figure to the eye ground and then the reflected image from the eye ground is detected by CCD. The image is then automatically identified by computer and the far point and near point diopters are determined to calculate lens parameter. This is a fully automatic objective optometry method which eliminates subjective factors of the tested subject. Furthermore, it can acquire the lens parameter of presbyopia accurately and quickly and can be used to measure the lens parameter of hyperopia, myopia and astigmatism.

Analysis of the actions of the novel dopamine receptor-directed compounds (S)-OSU6162 and ACR16 at the D2 dopamine receptor

PubMed Central

Kara, Elodie; Lin, Hong; Svensson, Kjell; Johansson, Anette M; Strange, Philip G

2010-01-01

BACKGROUND AND PURPOSE The two phenylpiperidines, OSU6162 and ACR16, have been proposed as novel drugs for the treatment of brain disorders, including schizophrenia and Huntington's disease, because of their putative dopamine stabilizing effects. Here we evaluated the activities of these compounds in a range of assays for the D2 dopamine receptor in vitro. EXPERIMENTAL APPROACH The affinities of these compounds for the D2 dopamine receptor were evaluated in competition with [3H]spiperone and [3H]NPA. Agonist activity of these compounds was evaluated in terms of their ability to stimulate [35S]GTPγS binding. KEY RESULTS Both compounds had low affinities for inhibition of [3H]spiperone binding (pKi vs. [3H]spiperone, ACR16: <5, OSU6162: 5.36). Neither compound was able to stimulate [35S]GTPγS binding when assayed in the presence of Na+ ions, but if the Na+ ions were removed, both compounds were low-affinity, partial agonists (Emax relative to dopamine: ACR16: 10.2%, OSU6162:54.3%). Schild analysis of the effects of OSU6162 to inhibit dopamine-stimulated [35S]GTPγS binding indicated Schild slopes of ∼0.9, suggesting little deviation from competitive inhibition. OSU6162 was, however, able to accelerate [3H]NPA dissociation from D2 dopamine receptors, indicating some allosteric effects of this compound. CONCLUSIONS AND IMPLICATIONS The two phenylpiperidines were low-affinity, low-efficacy partial agonists at the D2 dopamine receptor in vitro, possibly exhibiting some allosteric effects. Comparing their in vitro and in vivo effects, the in vitro affinities were a reasonable guide to potencies in vivo. However, the lack of in vitro–in vivo correlation for agonist efficacy needs to be further addressed. PMID:20804495

Attenuated Neural Processing of Risk in Young Adults at Risk for Stimulant Dependence

PubMed Central

Reske, Martina; Stewart, Jennifer L.; Flagan, Taru M.; Paulus, Martin P.

2015-01-01

Objective Approximately 10% of young adults report non-medical use of stimulants (cocaine, amphetamine, methylphenidate), which puts them at risk for the development of dependence. This fMRI study investigates whether subjects at early stages of stimulant use show altered decision making processing. Methods 158 occasional stimulants users (OSU) and 50 comparison subjects (CS) performed a “risky gains” decision making task during which they could select safe options (cash in 20 cents) or gamble them for double or nothing in two consecutive gambles (win or lose 40 or 80 cents, “risky decisions”). The primary analysis focused on risky versus safe decisions. Three secondary analyses were conducted: First, a robust regression examined the effect of lifetime exposure to stimulants and marijuana; second, subgroups of OSU with >1000 (n = 42), or <50 lifetime marijuana uses (n = 32), were compared to CS with <50 lifetime uses (n = 46) to examine potential marijuana effects; third, brain activation associated with behavioral adjustment following monetary losses was probed. Results There were no behavioral differences between groups. OSU showed attenuated activation across risky and safe decisions in prefrontal cortex, insula, and dorsal striatum, exhibited lower anterior cingulate cortex (ACC) and dorsal striatum activation for risky decisions and greater inferior frontal gyrus activation for safe decisions. Those OSU with relatively more stimulant use showed greater dorsal ACC and posterior insula attenuation. In comparison, greater lifetime marijuana use was associated with less neural differentiation between risky and safe decisions. OSU who chose more safe responses after losses exhibited similarities with CS relative to those preferring risky options. Discussion Individuals at risk for the development of stimulant use disorders presented less differentiated neural processing of risky and safe options. Specifically, OSU show attenuated brain response in regions critical for performance monitoring, reward processing and interoceptive awareness. Marijuana had additive effects by diminishing neural risk differentiation. PMID:26076493

This study is an investigation of how Australian and New Zealand schools of optometry prepare students for culturally competent practice. The aims are: (1) to review how optometric courses and educators teach and prepare their students to work with culturally diverse patients; and (2) to determine the demographic characteristics of current optometric students and obtain their views on cultural diversity. All Australian and New Zealand schools of optometry were invited to participate in the study. Data were collected with two surveys: a curriculum survey about the content of the optometric courses in relation to cultural competency issues and a survey for second year optometry students containing questions in relation to cultural awareness, cultural sensitivity and attitudes to cultural diversity. Four schools of optometry participated in the curriculum survey (Deakin University, Flinders University, University of Melbourne and University of New South Wales). Sixty-three students (22.3 per cent) from these four schools as well as the University of Auckland participated in the student survey. Cultural competency training was reported to be included in the curriculum of some schools, to varying degrees in terms of structure, content, teaching method and hours of teaching. Among second year optometry students across Australia and New Zealand, training in cultural diversity issues was the strongest predictor of cultural awareness and sensitivity after adjusting for school, age, gender, country of birth and language other than English. This study provides some evidence that previous cultural competency-related training is associated with better cultural awareness and sensitivity among optometric students. The variable approaches to cultural competency training reported by the schools of optometry participating in the study suggest that there may be opportunity for further development in all schools to consider best practice training in cultural competency. © 2014 The Authors.

L-Pyroglutamic acid succinimidyl ester (L-PGA-OSu) and its isotopic variant (L-PGA[d5]-OSu) were newly synthesized and evaluated as the chiral labeling reagents for the enantioseparation of amino acids, in terms of separation efficiency by reversed-phase chromatography and detection sensitivity by ESI-MS/MS. The enantiomers of amino acids were easily labeled with the reagents at 60°C within 10 min in an alkaline medium containing triethylamine. Although all the diastereomers derived from 18 proteolytic amino acids could not be satisfactorily separated, the pairs of 9 amino acids were completely separated by reversed-phase chromatography using the small particle (1.7 μm) ODS column (Rs=1.95-8.05). The characteristic daughter ions, i.e., m/z 84.04 and m/z 89.04, were detected from all the derivatives by the collision induced dissociation of the protonated molecular ions. A highly sensitive detection at a low-fmol level (0.5-3.2 fmol) was also obtained from the selected reaction monitoring (SRM) chromatograms. An isotope labeling strategy using light and heavy L-PGA-OSu for the differential analysis of the DL-amino acids in different sample groups is also presented in this paper. The differential analysis of biological sample (i.e., human serum) and food product (i.e., yogurt) were tried to demonstrate the efficiency of the proposed method. The ratios of the DL-amino acids in human serum samples, spiked with the different concentrations of D-amino acids, were determined by the procedures using L-PGA-OSu and L-PGA[d5]-OSu. The D/L ratios in the two sample groups at different concentrations of amino acids were similar to the theoretical values. Furthermore, the ratios of D/L-alanine values in different yogurt products were comparable to the ratios obtained from the d/l values using only light reagent (i.e., L-PGA-OSu). Consequently, the proposed strategy is useful for the differential analysis not only in biological samples but also in food products. Copyright © 2013 Elsevier B.V. All rights reserved.

Analysis by plaque reduction neutralization assay of intertypic rotaviruses suggests that gene reassortment occurs in vivo.

PubMed Central

1987-01-01

The SB-1A rotavirus recovered from a diarrheic piglet in the United States is a naturally occurring intertypic rotavirus. When studied by reciprocal neutralization tests, the SB-1A virus was similar, if not identical, to the porcine Gottfried virus (serotype 4) and the porcine OSU virus (serotype 5). Analysis of reassortant viruses prepared from the SB-1A virus and the serotype 2 human DS-1 virus revealed that the antigenic specificity of the outer capsid protein VP3 of SB-1A was shared with the OSU virus, while the antigenic specificity of another outer capsid protein, VP7, of SB-1A appeared to be shared with the Gottfried virus. This suggests that SB-1A is a naturally occurring reassortant rotavirus between OSU-like and Gottfried-like porcine rotaviruses. In addition, using a genetic approach, we found evidence that the fourth gene was responsible for the predominantly one-way cross-neutralizing reactivity between canine rotavirus strain CU-1 (serotype 3) and porcine rotavirus strains SB-1A (serotypes 4 and 5) and OSU (serotype 5). Assignment of hemagglutination function to the fourth genome segment of porcine rotaviruses SB-1A and OSU and canine rotavirus CU-1 confirmed a similar previous gene assignment established for certain rotaviruses. Analysis of single gene 4 substitution reassortants confirmed our previous finding that VP3 was as potent in stimulating neutralizing antibodies as VP7. The observations confirm the need for a binary system of rotavirus classification and nomenclature similar to that used for the influenza A viruses; in such a system the neutralization specificity of both VP3 and VP7 would be indicated.

2009-07-01

Competency standards for entry-level to the profession of optometry in Australia were first developed in 1993, revised in 1997 and expanded in 2000 to include therapeutic competency standards. The entry-level standards cover the competencies required by a person entering the profession without therapeutic endorsement of their registration. The therapeutic competency standards address the additional competencies required for therapeutic endorsement of registration. This paper presents a revised version of the universal (entry-level) and therapeutic competency standards for the profession of optometry in Australia in 2008. Expert members of the profession and representatives from schools of optometry, registration boards in Australia, state divisions of Optometrists Association Australia and the New Zealand Association of Optometrists were consulted in the process of updating the standards. Three new elements of competency have been added to the standards. Twenty-three new performance criteria with associated indicators have been added. Some performance criteria from the earlier document have been combined. Substantial alterations were made to the presentation of indicators throughout the document. The updated entry-level (universal) and therapeutic competency standards were adopted on behalf of the profession by the National Council of Optometrists Association Australia in November 2008. Competency standards are used by Australian and New Zealand registration authorities for the purposes of registration and therapeutic endorsement of registration via the Optometry Council of Australia and New Zealand accreditation and assessment processes. They have also been used as the basis of the World Council of Optometry Global Competency-Based Model.

Affiliations of community health centers with the accredited schools and colleges of optometry in the states and territories of the United States.

2008-10-01

In 2006, the American Optometric Association Community Health Center Committee surveyed schools/colleges of optometry in the United States and its territories to assess collaborations between community health centers and optometric institutions. The survey investigated the number and structure of affiliations that existed between Federally Qualified Health Centers and schools/colleges of optometry in the United States. The survey reached the schools through the American Optometric Association Faculty Relations Committee or personal contact (Inter-American University of Puerto Rico). The survey showed wide variation in affiliations of community health centers with optometry programs. Six schools had no affiliations, whereas the remaining 11 ranged from 1 to 14. Information relating to 37 community health centers was reported. Results showed that schools utilized community health centers for fourth-year students in 5 schools, and both third- and fourth-year students in the remaining 6 schools. Schools vary regarding how precepting is managed with either full-time faculty (64.9%) or adjunct faculty. Business models also vary between schools. Affiliations between school/colleges of optometry and community health centers differ considerably. Optometric affiliations with community health centers can result in increased access to eye care for underserved populations and increased clinical experience for optometry students and residents. Opportunities exist to establish additional affiliations. Educational benefits and costs associated with affiliations should be explored before entering into a collaborative model of eye care delivery.

Agricultural Aircraft Aid

1982-01-01

Farmers are increasingly turning to aerial applications of pesticides, fertilizers and other materials. Sometimes uneven distribution of the chemicals is caused by worn nozzles, improper alignment of spray nozzles or system leaks. If this happens, job must be redone with added expense to both the pilot and customer. Traditional pattern analysis techniques take days or weeks. Utilizing NASA's wind tunnel and computer validation technology, Dr. Roth, Oklahoma State University (OSU), developed a system for providing answers within minutes. Called the Rapid Distribution Pattern Evaluation System, the OSU system consists of a 100-foot measurement frame tied in to computerized analysis and readout equipment. System is mobile, delivered by trailer to airfields in agricultural areas where OSU conducts educational "fly-ins." A fly-in typically draws 50 to 100 aerial applicators, researchers, chemical suppliers and regulatory officials. An applicator can have his spray pattern checked. A computerized readout, available in five to 12 minutes, provides information for correcting shortcomings in the distribution pattern.

This study was conducted to evaluate the range of services provided by optometrists in various modes of optometric practice in India. An online questionnaire was administered to 1674 optometrists to collect information on the range of optometric services offered. Data were analyzed based on variables including sex, educational qualification, and modes of practice. Two-sample Wilcoxon rank sum tests, χ tests, and Fisher exact text were used to conduct inferential statistics. A total of 563 valid and completed survey questionnaires were received from graduates of 41 optometry institutes working across 23 states of India. Of these, 225 (40.0%) were female, 288 (51.2%) had completed postgraduate education, and 340 (60.5%) were involved in more than one mode of practice. The top three modes of practice were hospital-based practice (44.8%), academia (42.8%), and optical retail (33.0%). Of the 441, out of 563 (78.3%) respondents involved in patient care, the majority (98.4%) performed refraction and routine eye examination, 70.3% dispensed contact lenses, and 66.9% practiced optical dispensing. Lower involvement was seen in providing binocular-vision (45.1%) and low-vision services (30.2%). Higher education was associated with advanced level of practice (p < 0.05) except clinical investigative procedures. There was a significant association between postgraduate studies and involvement in academics and research (p < 0.01). Most optometrists are engaged in multiple modes of practice, with optical practice, hospital-based practice, and academia being the leading modes. Optometrists need to be more involved in providing the core optometric services of binocular vision and low vision. Higher education has an impact on the level of optometric practice.

Competency standards for entry-level to the profession of optometry in Australia were first developed in 1993, revised in 1997 and 2000, and again in 2008, when therapeutic competency standards were introduced but differentiated from the entry-level competencies. Therapeutic competencies were an additional requirement for the purpose of endorsing optometric registration to allow prescription of medicines for conditions of the eye. Recent changes to educational and registration requirements mean that therapeutic competencies are now required at entry-level. To address this and to ensure the standards reflect current best practice, a full revision of the standards was undertaken. A steering committee oversaw the review of the standards, which involved a literature review, workshops with optometrists and broad consultation with stakeholders, including the Optometry Board of Australia, individual optometrists and employers of optometrists, to identify changes needed. Representatives of the profession from Australia and New Zealand and from academia in Australia were involved. A modified document based on the feedback received was circulated to the State Divisions and the National Board of the then Optometrists Association Australia. The updated standards reflect the state of entry to the optometric profession in 2014; competencies for prescribing of scheduled medicines are included, new material has been added, other areas have been modified. The updated entry-level competency standards were adopted on behalf of the profession by the National Board of the then Optometrists Association Australia in March 2014. Competency standards have been updated so that they continue to be current and useful for the profession, individual optometrists and Australian and New Zealand registration authorities for the purposes of accreditation of optometric programs and assessment of overseas-trained optometrists. This paper details the revision process and presents the 2014 version of competency standards for entry-level to the profession of optometry in Australia. © 2014 The Authors.

N 1-benzylated dihydroquinolin-6-ols and their corresponding esters display exceptional activity against African trypanosomes in vitro, and administration of members of this class of compounds to trypanosome-infected mice results in cures in a first stage African trypanosomiasis model. Since a quinone imine intermediate has been implicated in the antiparasitic mechanism of action of these compounds, evaluation of the hepatotoxic, mutagenic, and methemoglobin-promoting effects of these agents was performed. 1-Benzyl-1,2-dihydro-2,2,4-trimethylquinolin-6-ol hydrochloride (OSU-36.HCl) and 1-benzyl-1,2-dihydro-2,2,4-trimethylquinolin-6-yl acetate (OSU-40) showed outstanding in vitro selectivity for T. brucei compared to the HepG2, Hep3B, Huh7 and PLC5 hepatocyte cell lines. OSU-36.HCl and 1-(2-methoxybenzyl)-1,2-dihydro-2,2,4-trimethylquinolin-6-yl acetate (OSU-75) were not mutagenic when screened in the Ames assay, with or without metabolic activation. The latter two compounds promoted time- and dose-dependent formation of methemoglobin when incubated in whole human blood, but such levels were below those typically required to produce symptoms of methemoglobinemia in humans. While compounds capable of quinone imine formation require careful evaluation, these in vitro studies indicate that antitrypanosomal dihydroquinolines merit further study as drug candidates against the neglected tropical disease human African trypanosomiasis.

What healthcare students do with what they don't know: the socializing power of 'uncertainty' in the case presentation.

PubMed

Spafford, Marlee M; Schryer, Catherine F; Lingard, Lorelei; Hrynchak, Patricia K

2006-01-01

Healthcare students learn to manage clinical uncertainty amid the tensions that emerge between clinical omniscience and the 'truth for now' realities of the knowledge explosion in healthcare. The case presentation provides a portal to viewing the practitioner's ability to manage uncertainty. We examined the communicative features of uncertainty in 31 novice optometry case presentations and considered how these features contributed to the development of professional identity in optometry students. We also reflected on how these features compared with our earlier study of medical students' case presentations. Optometry students, like their counterparts in medicine, displayed a novice rhetoric of uncertainty that focused on personal deficits in knowledge. While optometry and medical students shared aspects of this rhetoric (seeking guidance and deflecting criticism), optometry students displayed instances of owning limits while medical students displayed instances of proving competence. We found that the nature of this novice rhetoric was shaped by professional identity (a tendency to assume an attitude of moral authority or defer to a higher authority) and the clinical setting (inpatient versus outpatient settings). More explicit discussions regarding uncertainty may help the novice unlock the code of contextual forces that cue the savvy member of the community to sanctioned discursive strategies.

Human resources for refraction services in Central Nepal.

Kandel, Himal; Murthy, G V S; Bascaran, Covadonga

2015-07-01

Uncorrected refractive error is a public health problem globally and in Nepal. Planning of refraction services is hampered by a paucity of data. This study was conducted to determine availability and distribution of human resources for refraction, their efficiency, the type and extent of their training; the current service provision of refraction services and the unmet need in human resources for refraction in Central Nepal. This was a descriptive cross-sectional study. All refraction facilities in the Central Region were identified through an Internet search and interviews of key informants from the professional bodies and parent organisations of primary eye centres. A stratified simple random sampling technique was used to select 50 per cent of refraction facilities. The selected facilities were visited for primary data collection. Face-to-face interviews were conducted with the managers and the refractionists available in the facilities using a semi-structured questionnaire. Data was collected in 29 centres. All the managers (n=29; response rate 100 per cent) and 50 refractionists (Response rate 65.8 per cent) were interviewed. Optometrists and ophthalmic assistants were the main providers of refraction services (n=70, 92.11 per cent). They were unevenly distributed across the region, highly concentrated around urban areas. The median number of refractions per refractionist per year was 3,600 (IQR: 2,400 - 6,000). Interviewed refractionists stated that clients' knowledge, attitude and practice related factors such as lack of awareness of the need for refraction services and/or availability of existing services were the major barriers to the output of refraction services. The total number of refractions carried out in the Central Region per year was 653,176. An additional 170 refractionists would be needed to meet the unmet need of 1,323,234 refractions. The study findings demand a major effort to develop appropriately trained personnel when planning refraction services in the Central Region and in Nepal as a whole. The equitable distribution of the refractionists, their community-outreach services and awareness raising activities should be emphasised. © 2015 The Authors.

Vegetation/Ecosystem Modeling and Analysis Project:Comparing biogeography and biogeochemistry models in a continental-scale study of terrestrial ecosystem responses to climate change and CO2 doubling

NASA Astrophysics Data System (ADS)

1995-12-01

We compare the simulations of three biogeography models (BIOME2, Dynamic Global Phytogeography Model (DOLY), and Mapped Atmosphere-Plant Soil System (MAPSS)) and three biogeochemistry models (BIOME-BGC (BioGeochemistry Cycles), CENTURY, and Terrestrial Ecosystem Model (TEM)) for the conterminous United States under contemporary conditions of atmospheric CO2 and climate. We also compare the simulations of these models under doubled CO2 and a range of climate scenarios. For contemporary conditions, the biogeography models successfully simulate the geographic distribution of major vegetation types and have similar estimates of area for forests (42 to 46% of the conterminous United States), grasslands (17 to 27%), savannas (15 to 25%), and shrublands (14 to 18%). The biogeochemistry models estimate similar continental-scale net primary production (NPP; 3125 to 3772 × 1012 gC yr-1) and total carbon storage (108 to 118 × 1015 gC) for contemporary conditions. Among the scenarios of doubled CO2 and associated equilibrium climates produced by the three general circulation models (Oregon State University (OSU), Geophysical Fluid Dynamics Laboratory (GFDL), and United Kingdom Meteorological Office (UKMO)), all three biogeography models show both gains and losses of total forest area depending on the scenario (between 38 and 53% of conterminous United States area). The only consistent gains in forest area with all three models (BIOME2, DOLY, and MAPSS) were under the GFDL scenario due to large increases in precipitation. MAPSS lost forest area under UKMO, DOLY under OSU, and BIOME2 under both UKMO and OSU. The variability in forest area estimates occurs because the hydrologic cycles of the biogeography models have different sensitivities to increases in temperature and CO2. However, in general, the biogeography models produced broadly similar results when incorporating both climate change and elevated CO2 concentrations. For these scenarios, the NPP estimated by the biogeochemistry models increases between 2% (BIOME-BGC with UKMO climate) and 35% (TEM with UKMO climate). Changes in total carbon storage range from losses of 33% (BIOME-BGC with UKMO climate) to gains of 16% (TEM with OSU climate). The CENTURY responses of NPP and carbon storage are positive and intermediate to the responses of BIOME-BGC and TEM. The variability in carbon cycle responses occurs because the hydrologic and nitrogen cycles of the biogeochemistry models have different sensitivities to increases in temperature and CO2. When the biogeochemistry models are run with the vegetation distributions of the biogeography models, NPP ranges from no response (BIOME-BGC with all three biogeography model vegetations for UKMO climate) to increases of 40% (TEM with MAPSS vegetation for OSU climate). The total carbon storage response ranges from a decrease of 39% (BIOME-BGC with MAPSS vegetation for UKMO climate) to an increase of 32% (TEM with MAPSS vegetation for OSU and GFDL climates). The UKMO responses of BIOME-BGC with MAPSS vegetation are primarily caused by decreases in forested area and temperature-induced water stress. The OSU and GFDL responses of TEM with MAPSS vegetations are primarily caused by forest expansion and temperature-enhanced nitrogen cycling.

Creating and evaluating a new clicker methodology

NASA Astrophysics Data System (ADS)

Li, Pengfei

"Clickers", an in-class polling system, has been used by many instructors to add active learning and formative assessment to previously passive traditional lectures. While considerable research has been conducted on clicker increasing student interaction in class, less research has been reported on the effectiveness of using clicker to help students understand concepts. This thesis reported a systemic project by the OSU Physics Education group to develop and test a new clicker methodology. Clickers question sequences based on a constructivist model of learning were used to improve classroom dynamics and student learning. They also helped students and lecturers understand in real time whether a concept had been assimilated or more effort was required. Chapter 1 provided an introduction to the clicker project. Chapter 2 summarized widely-accepted teaching principles that have arisen from a long history of research and practice in psychology, cognitive science and physics education. The OSU clicker methodology described in this thesis originated partly from our years of teaching experience, but mostly was based on these teaching principles. Chapter 3 provided an overview of the history of clicker technology and different types of clickers. Also, OSU's use of clickers was summarized together with a list of common problems and corresponding solutions. These technical details may be useful for those who want to use clickers. Chapter 4 discussed examples of the type and use of question sequences based on the new clicker methodology. In several years of research, we developed a base of clicker materials for calculus-based introductory physics courses at OSU. As discussed in chapter 5, a year-long controlled quantitative study was conducted to determine whether using clickers helps students learn, how using clickers helps students learn and whether students perceive that clicker has a positive effect on their own learning process. The strategy for this test was based on comparing clicker lecture sections using the new methodology to lecture sections with a similar population of students taught without clickers in a traditional manner. The results of this test were summarized in chapter 5. Chapter 6 contains a brief summary of research results and conclusions, together with an overview of future efforts in the OSU clicker project.

A cross-sectional survey of optometrists and optometric practices in Ghana.

The study was conducted to profile optometrists and optometric practices in Ghana. An online survey was conducted among 146 optometrists, who were registered with the Ghana Optometric Association (GOA). It included questions on their demographics, equipment, ophthalmic procedures routinely conducted and the barriers to providing a full scope of optometric services. Ninety registered optometrists (62 per cent) responded, their mean age being 28.97 ± 3.36 years. There were more males (68.9 per cent) than females and most had the Doctor of Optometry (OD) degree, the profession's highest degree in Ghana. There were more practitioners in urban centres (71.1 per cent) and most practices had basic optometric instruments, such as direct ophthalmoscopes, slitlamp biomicroscopes and retinoscopes. Many optometrists routinely conducted direct ophthalmoscopy (100 per cent), slitlamp biomicroscopy (87.5 per cent) and contact tonometry (55.7 per cent); however, few provided contact lens (10.2 per cent) and low vision (9.1 per cent) assessments, with 76 per cent stating that it was due to the unavailability of low vision devices, poor sources of contact lenses (27 per cent) and perceived insufficient training (11.2 per cent). Many practitioners (97 per cent) reported the use of diagnostic pharmaceutical agents and therapeutic pharmaceutical agents (96.6 per cent). Most practitioners (52.9 per cent) preferred conferences for the delivery of continuous professional development over publications (26.4 per cent) and internet resources (12.6 per cent).

Rider, Shyla K; Oeder, Jessica L; Nguyen, Trang T; Rodis, Jennifer L

2014-06-01

An innovative program to help pharmacy students navigate the residency application and interview process is described, including results of a survey evaluating the program's impact. The Ohio State University (OSU) chapter of the Student Society of Health-System Pharmacy (SSHP) collaborated with OSU College of Pharmacy faculty members, pharmacists from OSU Wexner Medical Center and surrounding areas, and current pharmacy residents to provide programming to equip pharmacy students with skills to succeed as residency candidates. The programming has four components: Curriculum Vitae (CV) Critique, Mock Residency Interviews, Residency 101, and Midyear to Match (M-M), a six-part series that provides guidance on the Residency Showcase at the American Society of Health-System Pharmacists (ASHP) Midyear Clinical Meeting, Match day (the annual matching process coordinated by ASHP), and the post-Match "scramble," in which unmatched applicants compete for unfilled residency slots. In an online survey conducted by the SSHP chapter after the 2012-13 residency year, 26 of 57 survey respondents indicated they had pursued a residency. Twenty respondents reported success in the Match (a rate 15% higher than the national average), with 9 reporting acceptance by their first-choice residency site. The mock interview program was rated as the most useful (a mean score of 4.8 on a 5-point scale), followed by the M-M series (mean score, 4.6). Collaborative programming coordinated by the OSU chapter of SSHP was offered to pharmacy students to improve preparation for the residency application and interview process. The program was well received by participants. Copyright © 2014 by the American Society of Health-System Pharmacists, Inc. All rights reserved.

2012-01-01

A study was completed to assess the academic and state-level professional optometry leadership views regarding optometry professionals as surge responders in the event of a catastrophic event. A cross-sectional survey was conducted using a 21-question, self-administered, structured questionnaire. All U.S. optometry school deans and state optometric association presidents were mailed a questionnaire and instructions to return it by mail on completion; 2 repeated mailings were made. Descriptive statistics were produced and differences between deans and association presidents were tested by Fisher exact test. The questionnaire response rate was 50% (25 returned/50 sent) for the state association presidents and 65% (11/17) for the deans. There were no statistically significant differences between the leadership groups for any survey questions. All agreed that optometrists have the skills, are ethically obligated to help, and that optometrists should receive additional training for participation in disaster response. There was general agreement that optometrists should provide first-aid, obtain medical histories, triage, maintain infection control, manage a point of distribution, prescribe medications, and counsel the "worried well." Starting intravenous lines, interpreting radiographs, and suturing were less favorably supported. There was some response variability between the 2 leadership groups regarding potential sources for training. The overall opinion of optometry professional leadership is that with additional training, optometrists can and should provide an important reserve pool of catastrophic event responders.

MELCOR Analysis of OSU Multi-Application Small Light Water Reactor (MASLWR) Experiment

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yoon, Dhongik S.; Jo, HangJin; Fu, Wen

A multi-application small light water reactor (MASLWR) conceptual design was developed by Oregon State University (OSU) with emphasis on passive safety systems. The passive containment safety system employs condensation and natural circulation to achieve the necessary heat removal from the containment in case of postulated accidents. Containment condensation experiments at the MASLWR test facility at OSU are modeled and analyzed with MELCOR, a system-level reactor accident analysis computer code. The analysis assesses its ability to predict condensation heat transfer in the presence of noncondensable gas for accidents where high-energy steam is released into the containment. This work demonstrates MELCOR’s abilitymore » to predict the pressure-temperature response of the scaled containment. Our analysis indicates that the heat removal rates are underestimated in the experiment due to the limited locations of the thermocouples and applies corrections to these measurements by conducting integral energy analyses along with CFD simulation for confirmation. Furthermore, the corrected heat removal rate measurements and the MELCOR predictions on the heat removal rate from the containment show good agreement with the experimental data.« less

Faucher, Caroline; Dufour-Guindon, Marie-Pier; Lapointe, Gabrielle; Gagnon, Robert; Charlin, Bernard

2016-05-01

Clinical reasoning is central to any health profession but its development among learners is difficult to assess. Over the last few decades, the script concordance test (SCT) has been developed to solve this dilemma and has been used in many health professions; however, no study has been published on the use of the script concordance test in optometry. The purpose of this study was to develop and validate a script concordance test for the field of optometry. A 101-question script concordance test (27 short clinical scenarios) was developed and administered online to a convenience sample of 23 second-year and 19 fourth-year students of optometry. It was also administered to a reference panel of 12 experienced optometrists to develop the scoring key. An item-total correlation was calculated for each question. Cronbach's alpha coefficient was used to evaluate the script concordance test reliability and a t-test compared the two groups. A final 77-question script concordance test was created by eliminating questions with low item-total correlation. Cronbach's alpha for this optimised 77-question script concordance test was 0.80. A group comparison revealed that the second-year students' scores (n = 23; mean score = 66.4 ± 7.87 per cent) were statistically lower (t = -4.141; p < 0.001) than those of the fourth-year students (n = 19; mean score = 75.5 ± 5.97 per cent). The online script concordance test developed for this study was found to be both reliable and capable of discriminating between second- and fourth-year optometric students. These results demonstrate that the script concordance test may be considered as a new tool in the optometric educators' assessment arsenal. Further studies will be needed to cover additional levels of professional development. © 2016 The Authors. Clinical and Experimental Optometry © 2016 Optometry Australia.

Report the prevalence of lifetime and military-related traumatic brain injuries (TBIs) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans and validate the Boston Assessment of TBI-Lifetime (BAT-L). The BAT-L is the first validated, postcombat, semistructured clinical interview to characterize head injuries and diagnose TBIs throughout the life span. Community-dwelling convenience sample of 131 OEF/OIF veterans. TBI criteria (alteration of mental status, posttraumatic amnesia, and loss of consciousness) were evaluated for all possible TBIs, including a novel evaluation of blast exposure. BAT-L, Ohio State University TBI Identification Method (OSU-TBI-ID). About 67% of veterans incurred a TBI in their lifetime. Almost 35% of veterans experienced at least 1 military-related TBI; all were mild in severity, 40% of them were due to blast, 50% were due to some other (ie, blunt) mechanism, and 10% were due to both types of injuries. Predeployment TBIs were frequent (45% of veterans). There was strong correspondence between the BAT-L and the OSU-TBI-ID (Cohen κ = 0.89; Kendall τ-b = 0.95). Interrater reliability of the BAT-L was strong (κs >0.80). The BAT-L is a valid instrument with which to assess TBI across a service member's lifetime and captures the varied and complex nature of brain injuries across OEF/OIF veterans' life span.

To explore the views of optometrists, general practitioners (GPs) and ophthalmologists regarding the development and organisation of community-based enhanced optometric services. Qualitative study using free-text questionnaires and telephone interviews. A minor eye conditions scheme (MECS) and a glaucoma referral refinement scheme (GRRS) are based on accredited community optometry practices. 41 optometrists, 6 ophthalmologists and 25 GPs. The most common reason given by optometrists for participation in enhanced schemes was to further their professional development; however, as providers of 'for-profit' healthcare, it was clear that participants had also considered the impact of the schemes on their business. Lack of fit with the 'retail' business model of optometry was a frequently given reason for non-participation. The methods used for training and accreditation were generally thought to be appropriate, and participating optometrists welcomed the opportunities for ongoing training. The ophthalmologists involved in the MECS and GRRS expressed very positive views regarding the schemes and widely acknowledged that the new care pathways would reduce unnecessary referrals and shorten patient waiting times. GPs involved in the MECS were also very supportive. They felt that the scheme provided an 'expert' local opinion that could potentially reduce the number of secondary care referrals. The results of this study demonstrated strong stakeholder support for the development of community-based enhanced optometric services. Although optometrists welcomed the opportunity to develop their professional skills and knowledge, enhanced schemes must also provide a sufficient financial incentive so as not to compromise the profitability of their business.

To compare the efficacy of behavioral activation (BA) plus low vision rehabilitation with an occupational therapist (OT-LVR) with supportive therapy (ST) on visual function in patients with age-related macular degeneration (AMD). Single-masked, attention-controlled, randomized clinical trial with AMD patients with subsyndromal depressive symptoms (n = 188). All subjects had two outpatient low vision rehabilitation optometry visits, then were randomized to in-home BA + OT-LVR or ST. Behavioral activation is a structured behavioral treatment aiming to increase adaptive behaviors and achieve valued goals. Supportive therapy is a nondirective, psychological treatment that provides emotional support and controls for attention. Functional vision was assessed with the activity inventory (AI) in which participants rate the difficulty level of goals and corresponding tasks. Participants were assessed at baseline and 4 months. Improvements in functional vision measures were seen in both the BA + OT-LVR and ST groups at the goal level (d = 0.71; d = 0.56 respectively). At the task level, BA + OT-LVR patients showed more improvement in reading, inside-the-home tasks and outside-the-home tasks, when compared to ST patients. The greatest effects were seen in the BA + OT-LVR group in subjects with a visual acuity ≥20/70 (d = 0.360 reading; d = 0.500 inside the home; d = 0.468 outside the home). Based on the trends of the AI data, we suggest that BA + OT-LVR services, provided by an OT in the patient's home following conventional low vision optometry services, are more effective than conventional optometric low vision services alone for those with mild visual impairment.

U12 intron-specific spliceosomes contain U11 and U12 small nuclear ribonucleoproteins and mediate the removal of U12 introns from precursor-mRNAs. Among the several proteins unique to the U12-type spliceosomes, an Arabidopsis thaliana AtU11/U12-31K protein has been shown to be indispensible for proper U12 intron splicing and for normal growth and development of Arabidopsis plants. Here, we assessed the functional roles of the rice (Oryza sativa) OsU11/U12-31K protein in U12 intron splicing and development of plants. The U11/U12-31K transcripts were abundantly expressed in the shoot apical meristems (SAMs) of Arabidopsis and rice. Ectopic expression of OsU11/U12-31K in AtU11/U12-31K-defecient Arabidopsis mutant complemented the incorrect U12 intron splicing and abnormal development phenotypes of the Arabidopsis mutant plants. Impaired cell division activity in the SAMs and inflorescence stems observed in the AtU11/U12-31K-deficient mutant was completely recovered to normal by the expression of OsU11/U12-31K. Similar to Arabidopsis AtU11/U12-31K, rice OsU11/U12-31K was determined to harbor RNA chaperone activity. Collectively, the present findings provide evidence for the emerging idea that the U11/U12-31K protein is an indispensible RNA chaperone that functions in U12 intron splicing and is necessary for normal development of monocotyledonous plants as well as dicotyledonous plants.

2004-10-01

There is an apparent increase in the number of private optometry practices that are closing due to a lack of interested buyers. We examined some of the factors that influence the market for optometry practices in a survey of practicing optometrists and third- and fourth-year optometry students. Optometrists in six states, and students at four schools and colleges of optometry, completed a mailed or faxed survey regarding attitudes toward optometric practice, including fair/reasonable compensation for a new optometrist, the value of optometric practices, and preferred mode of practice on graduation. Doctors and students differed significantly in the amount of money they reported as fair/reasonable compensation for a recently graduated optometrist joining a practice. Comparing students to doctors in specific categories of compensation, students chose a higher fair/reasonable compensation compared to doctors. Students were more likely than doctors to choose >$70,000 as fair/reasonable compensation, while doctors were more likely than students to choose $40,000 to $69,000. Doctors tended to overvalue their practices for the purpose of selling the practice when using percentage of gross income as a valuation method. Students' choices for mode of practice changed dramatically from their ideal when taking their current financial situation into consideration. Students were more likely to choose corporate practice as their preferred practice mode when considering their current financial situation than when not restricted. There are many factors that affect the value and marketability of an optometric practice. In order to sell a practice, the owner must consider the effects of the needs and desires of recently graduated optometrists.

2013-12-01

The purpose of this study was to survey entering college students’ awareness of the profession of audiology, as well as to compare the students’ awareness of audiology to their awareness of roles in 2 other doctoral-level professions. A survey examining students’ awareness and perception of the profession of audiology was administered in 2009 at the California University of Pennsylvania (Emanuel, Donai, & Araj, 2012). A modified survey, which included questions about awareness of the profession of audiology as well as podiatry and optometry, was distributed in 2012. Survey data suggest that, overall, students were more accurate in describing the profession of optometry compared to audiology, but no difference existed between their awareness of podiatry and audiology. However, students with self-reported awareness of the three professions were more accurate in describing the professions of podiatry and optometry as compared to audiology. Results of this distribution suggest an upward trend in audiology awareness among students. However, the awareness of audiology as a potential career path is low relative to that of the professions of optometry and podiatry for those with self-reported knowledge. Future surveys should be distributed to entering college students at other universities, varying in size, location, and demographics.

Neuropsychological Performance in Polyconsumer Men Under Treatment. Influence of Age of Onset of Substance Use

Capella, Maria del Mar; Benaiges, Irina; Adan, Ana

2015-01-01

Neurocognition is a key factor in the development and maintenance of Substance Use Disorders (SUD). However, there are still several aspects that need to be studied in this area. In this study, we elucidate the influence of age of onset of substance use (OSU) on the clinical course and neuropsychological performance of substance use disorder (SUD) patients, as well as to explore the influence of years of education, duration of drug use and premorbid intelligence quotient (IQ) on the cognitive results obtained. An exhaustive neuropsychological battery was used to assess different cognitive domains in 80 male polyconsumers, 41 with earlier OSU (16 years or before: OSU ≤ 16) and 39 with later OSU (17 years or later: OSU ≥ 17). The patients were under treatment with at least 4 months of abstinence confirmed by urinalysis. The OSU ≤ 16 group presented a worse clinical state, as well as a lower premorbid IQ and worse performance in processing speed, visual perception and planning skills. The duration of drug use may account for the differences in planning and processing speed. In this work we discuss the premorbid or acquired nature of the cognitive deficits found. PMID:26155725

Hydrogeology and geochemistry of low-permeability oil-shales - Case study from HaShfela sub-basin, Israel

Burg, Avihu; Gersman, Ronen

2016-09-01

Low permeability rocks are of great importance given their potential role in protecting underlying aquifers from surface and buried contaminants. Nevertheless, only limited data for these rocks is available. New appraisal wells drilled into the oil shale unit (OSU) of the Mt. Scopus Group in the HaShfela sub-basin, Central Israel, provided a one-time opportunity for detailed study of the hydrogeology and geochemistry of this very low permeability unit. Methods used include: slug tests, electrical logs, televiewer imaging, porosity and permeability measurements on core samples, chemical analyses of the rock column and groundwater analyses. Slug tests yielded primary indication to the low permeability of the OSU despite its high porosity (30-40%). Hydraulic conductivities as low as 10-10-10-12 m/s were calculated, using both the Hvorslev and Cooper-Bredehoeft-Papadopulos decoding methods. These low conductivities were confirmed by direct measurements of permeability in cores, and from calculations based on the Kozeny-Carman approach. Storativity was found to be 1 · 10-6 and specific storage - 3.8 · 10-9 m-1. Nevertheless, the very limited water flow in the OSU is argued to be driven gravitationally. The extremely slow recovery rates as well as the independent recovery of two adjacent wells, despite their initial large head difference of 214 m, indicate that the natural fractures are tight and are impermeable due to the confining stress at depth. Laboratory measured permeability is similar or even higher than the field-measured values, thereby confirming that fractures and bedding planes do not form continuous flow paths. The vertical permeability along the OSU is highly variable, implying hydraulic stratification and extremely low vertical hydraulic conductivity. The high salinity of the groundwater (6300-8000 mgCl/L) within the OSU and its chemical and isotopic compositions are explained by the limited water flow, suggesting long residence time of the water, prolonged water-rock interaction and mixing with ancient trapped salty water. The current study demonstrates that targeted and detailed research of low permeability rocks can produce reliable hydraulic parameters using slug tests and accompanying methods. The data produced is of upmost importance for quantitative risk evaluations such as models for waste burial in low permeability units.

Strong leadership and teamwork drive culture and performance change: Ohio State University Medical Center 2000-2006.

Several characteristics of academic health centers have the potential to create high levels of internal conflict and misalignment that can pose significant leadership challenges. In September 2000, the positions of Ohio State University (OSU) senior vice president for health sciences, dean of the medical school, and the newly created position of chief executive officer of the OSU Medical Center (OSUMC) were combined under a single leader to oversee the OSUMC. This mandate from the president and trustees was modeled after top institutions with similar structures. The leader who assumed the role was tasked with improving OSUMC's academic, clinical, and financial performance. To achieve this goal, the senior vice president and his team employed the service value chain model of improving performance, based on the premise that leadership behavior/culture drives employee engagement/satisfaction, leading to customer satisfaction and improved organizational performance. Implementing this approach was a seven-step process: (1) selecting the right leadership team, (2) assessing the challenges and opportunities, (3) setting expectations for performance and leadership behavior, (4) aligning structures and functions, (5) engaging constituents, (6) developing leadership skills, and (7) defining strategies and tracking goals. The OSUMC setting during this period provides an observational case study to examine how these stepwise changes, instituted by strong leadership and teamwork, were able to make and implement sound decisions that drove substantial and measurable improvements in the engagement and satisfaction of faculty and staff; the satisfaction of students and patients; and academic, clinical, and financial performance.

Objective Report the prevalence of lifetime and military-related traumatic brain injuries (TBIs) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans and validate the Boston Assessment of TBI–Lifetime (BAT-L). Setting The BAT-L is the first validated, postcombat, semistructured clinical interview to characterize head injuries and diagnose TBIs throughout the life span. Participants Community-dwelling convenience sample of 131 OEF/OIF veterans. Design TBI criteria (alteration of mental status, posttraumatic amnesia, and loss of consciousness) were evaluated for all possible TBIs, including a novel evaluation of blast exposure. Main Measures BAT-L, Ohio State University TBI Identification Method (OSU-TBI-ID). Results About 67% of veterans incurred a TBI in their lifetime. Almost 35% of veterans experienced at least 1 military-related TBI; all were mild in severity, 40% of them were due to blast, 50% were due to some other (ie, blunt) mechanism, and 10% were due to both types of injuries. Predeployment TBIs were frequent (45% of veterans). There was strong correspondence between the BAT-L and the OSU-TBI-ID (Cohen κ = 0.89; Kendall τ-b 0.95). Interrater reliability of the BAT-L was strong (κs >0.80). Conclusions The BAT-L is a valid instrument with which to assess TBI across a service member’s lifetime and captures the varied and complex nature of brain injuries across OEF/OIF veterans’ life span.

2015-01-01

Background: School vision testing aims at identification and management of refractive errors. Large-scale school vision testing using conventional methods is time-consuming and demands a lot of chair time from the eye care professionals. A new strategy involving a school of optometry in single day large scale school vision testing is discussed. Aim: The aim was to describe a new approach of performing vision testing of school children on a large scale in a single day. Materials and Methods: A single day vision testing strategy was implemented wherein 123 members (20 teams comprising optometry students and headed by optometrists) conducted vision testing for children in 51 schools. School vision testing included basic vision screening, refraction, frame measurements, frame choice and referrals for other ocular problems. Results: A total of 12448 children were screened, among whom 420 (3.37%) were identified to have refractive errors. 28 (1.26%) children belonged to the primary, 163 to middle (9.80%), 129 (4.67%) to secondary and 100 (1.73%) to the higher secondary levels of education respectively. 265 (2.12%) children were referred for further evaluation. Conclusion: Single day large scale school vision testing can be adopted by schools of optometry to reach a higher number of children within a short span. PMID:25709271

Purpose To compare the effectiveness of an educational board game with interactive didactic instruction for teaching optometry students elements of the core optometric curriculum. Methods Forty-two optometry students were divided into two GPA-matched groups and assigned to either 12 hours of game play (game group) or 12 hours of interactive didactic instruction (lecture group). The same material from the core optometric curriculum was delivered to both groups. Game play was accomplished via an original board game. Written examinations assessed change in knowledge level. A post-intervention opinion survey assessed student attitudes. Results There was no significant difference in pre- or post-intervention test scores between the lecture and game groups (Pre-test: p = 0.9; Post-test: p = 0.5). Post-intervention test scores increased significantly from baseline (Game group: 29.3% gain, Didactic group: 31.5% gain; p<0.001 for each). The score increase difference between groups was not statistically significant (p = 0.6). The post-intervention attitude survey did not reveal any significant between group differences (p = 0.5). Conclusions Our results indicate that an educational game and interactive didactic instruction can be equally effective in teaching optometry students basic and applied science. Furthermore, both modes of instruction have the potential to be equally engaging and enjoyable experiences. PMID:27233041

Models for joint ophthalmology-optometry patient management.

Kim, John J; Kim, Christine M

2011-07-01

American Academy of Ophthalmology (AAO) and American Society of Cataract and Refractive Surgery (ASCRS) presented a joint position paper in February 2000 declaring that they do not support routine comanagement of patients with the optometrists. American Optometric Association and American Academy of Optometry quickly responded in support of AAO and ASCRS. All four entities did not preclude legitimate and proper comanagement arrangements. Since that time, the pattern of practice has changed, requiring us to rethink our positions. This paper is written to provide a possible model for the ophthalmology-optometry practice management in ophthalmic surgeries including refractive surgery. Since the publication of the Joint Position Paper, the concept of comanagement has faded and a new model of integrated management has evolved. This has occurred as the changes in the employment pattern of the ophthalmic practice have incorporated optometrists into its fold. This evolution allowed ophthalmic and optometric community to co-exist and thrive to provide better patient care.

A proposed minimum data set for international primary care optometry: a modified Delphi study.

2017-07-01

To identify a minimum list of metrics of international relevance to public health, research and service development which can be extracted from practice management systems and electronic patient records in primary optometric practice. A two stage modified Delphi technique was used. Stage 1 categorised metrics that may be recorded as being part of a primary eye examination by their importance to research using the results from a previous survey of 40 vision science and public health academics. Delphi stage 2 then gauged the opinion of a panel of seven vision science academics and achieved consensus on contentious metrics and methods of grading/classification. A consensus regarding inclusion and response categories was achieved for nearly all metrics. A recommendation was made of 53 metrics which would be appropriate in a minimum data set. This minimum data set should be easily integrated into clinical practice yet allow vital data to be collected internationally from primary care optometry. It should not be mistaken for a clinical guideline and should not add workload to the optometrist. A pilot study incorporating an additional Delphi stage prior to implementation is advisable to refine some response categories. © 2017 The Authors.

Optometric labour market projections are provided. First, population growth and ageing-based estimates of the rate of increase of eye-care services in Ontario from 2011 to 2$ are presented, holding the age-sex structure of utilization constant. Then, using data on the 2011 supply and working hours of Ontario's optometrists, the number of optometrists needed to keep the level of optometric services per age-sex-adjusted person comparable over time is estimated. The projections suggest that the number of Ontario optometrists should grow by approximately 30-40 full-time equivalents per year; to offset retirements and account for decreasing work hours, this suggests 77-90 new practitioners are required each year. However, in recent years, the number of Ontario optometrists has been growing faster than this, suggesting either that demand has exceeded supply and/or surpluses will accumulate if this trend continues.

Understanding patient perceptions of having students involved in their clinical care is important as we strive to develop optimal models of care that integrate teaching with the best possible experience for the patient. The aim was to ascertain the impact of supervised optometry student consultations on the patient experience. A survey comprising 45 questions was mailed to consecutive adult patients who had undergone a comprehensive eye examination at the Australian College of Optometry over a four-week period. Responses were received from 193 patients who had a student involved in their care (44 per cent response rate; 156 completed correctly) and 177 who did not have a student involved (32 per cent response rate; 105 completed correctly). There was no significant difference in overall patient satisfaction between the teaching and non-teaching clinics (p = 0.18). Over 87 per cent of patients in the teaching clinic felt completely comfortable with a student examining them, 44 per cent felt their care was better because a student was involved and 97 per cent rated the overall performance of the student as very good or good. Although 12 per cent would rather have seen only the optometrist and three per cent would not be happy to have a student involved in their eye care again, 100 per cent believed it is important for students to work with patients. The most common reason for student acceptance was the importance of students needing opportunities to learn. The main reasons for unwillingness to have a student involved in future were the additional time taken and prolonged testing. The findings of this study suggest that most patients view supervised student involvement in their optometric care as an important and highly positive experience. However, efforts should be made to avoid excessively long consultations and prolonged testing. Concerns about patient satisfaction and acceptance are largely unwarranted and should not prevent optometry students being involved in patient care. © 2017 Optometry Australia.

Some universities are looking to provide a more diverse range of clinical learning experiences through extended clinical placement programs. This approach will potentially have a significant impact on practitioners. The aim of this study was to conduct a national survey of optometrists to ascertain their perspectives on participating in extended clinical placement programs. Members of Optometry Australia were invited to participate in a survey conducted during June and July 2014. A total of 268 practitioners participated (six per cent of registered Australian optometrists): 159 were predominantly employees or locums and 109 were owners or managers who identified as the key representative of a practice or organisation for the purpose of this survey. Almost two-thirds (65 per cent) of participants, who were employees or locums were supportive of extended clinical placement programs. Among this group, females were more likely to be supportive than males (p = 0.033). In comparison, just over one-third (34 per cent) of participants who were key decision-makers were supportive, with 30 per cent possibly supportive and 36 per cent not supportive. Among key decision-makers, males were more likely to be supportive (p = 0.009). The top three perceived advantages of supervising a student were: opportunity to mentor early career development, opportunity to give back to the profession and future recruitment. The top three perceived disadvantages were: burden on time, decrease in number of patients examined and burden on support staff. Suggested incentives for supervising students were credit for continuing professional development and financial remuneration. There appears to be moderate support for extended clinical placement programs; however, there are incentives that might engage a larger proportion of the profession in the future. These findings can inform the development of effective and sustainable clinical training programs for optometry students. Additionally, the findings might be used as evidence to seek Government support for clinical placement training in optometry. © 2016 Optometry Australia.

Advanced ultrasound training for fourth-year medical students: a novel training program at The Ohio State University College of Medicine.

Bahner, David P; Royall, Nelson A

2013-02-01

Ultrasound training and education in medical schools is rare, and the foci of current ultrasound curricula are limited. There is a significant need for advanced ultrasound training models in medical school curricula to reduce educational burdens for physician residency programs and improve overall physician competency.The authors describe and evaluate the advanced ultrasound training program developed at The Ohio State University College of Medicine (OSU COM). The OSU COM program is a longitudinal advanced ultrasound curriculum for fourth-year medical students pursuing specialties that require frequent use of focused ultrasound. One hundred fifty student participants have completed the yearlong program to date. Participants engage in didactic lectures, journal club sessions, hands-on training, teaching and patient-modeling activities, and complete a final project. Experienced Ohio State University Medical Center faculty are recruited from specialties that frequently use ultrasound (e.g., emergency medicine, internal medicine, obstetrics-gynecology). A multimodal instructional assessment approach ensures that ultrasound training yields experience with cognitive, behavioral, and constructive learning components. The authors discuss the benefits of the program as well as its challenges and future directions.The advanced ultrasound training program at OSU COM demonstrates a novel approach to providing ultrasound training for medical students, offering a feasible model for meeting training guidelines without increasing the educational requirements for residency programs.

Using a bibliometric approach an analysis was made of the scientific publications of Spanish investigators in the area of optometry, from 1974 until 2013. The EMBASE database was used for this study, employing optomtr*, optic*, visual, vision, eye*, and ophthalm* as search terms. The most common bibliometric indicators were applied for the selected publications. The number of published articles retrieved for Spain from 1974-2013 was 1,055. The growth of publications was more exponential (R=0.93) than linear (R= 0.71). The doubling time of scientific production was 3.63 years. The level of productivity primarily corresponded to small producers (Transience index of 64%). The collaboration index was 4.4 authors per paper. The majority of the output was generated in academic settings (62.27%). The Bradford core was formed by four journals, in which Optometry and Vision Science accounted for the majority of publications, with 11.85%. Research in the area of optometry in Spain is in a phase of exponential growth, containing a high level of transient authors, which may indicate either a low productivity or the presence of investigators from other related fields that have published in a sporadic manner in this area. A small number of research groups are responsible for producing the majority of articles, primarily in an academic setting. There is a high concentration of publications in a few journals.

Tensions in the field: teaching standards of practice in optometry case presentations.

PubMed

Spafford, Marlee M; Lingard, Lorelei; Schryer, Catherine F; Hrynchak, Patricia K

2004-10-01

Professional identity formation and its relationship to case presentations were studied in an optometry school's onsite clinic. Eight optometry students and six faculty optometrists were audio-recorded during 31 oral case presentations and the teaching exchanges related to them. Using convenience sampling, interviews were audio-recorded of four of the students and four of the optometrists from the field observations. After transcribing these audio-recordings, the research team members applied a grounded theory method to identify, test, and revise emergent themes. The theme reported herein pertains to communicating standards of practice. Faculty optometrists demonstrated three ways of communicating standards of practice to optometry students during case presentations: Official Way, Our Way, and My Way. Although there were differences between these standards, the rationale for the disparities was rarely explicitly articulated by the instructors to the students. Without this information, the incongruity among the standards was left to the students to interpret on their own. The risk created by faculty not articulating the rationale underlying standards of practice was that students misinterpreted the optometrists' ways as idiosyncratic. Thus, opportunities were missed in the educational setting to assist students in making responsible decisions, locating their position in practice, and shaping their professional identity. Competing responsibilities of patient care and student education left instructors with little time to articulate rationale for standards of practice. Therefore, educators must reflect on innovative ways to bring into relief the logic behind their actions when working with novices.

We provide the first calculation of the hadronic disk component in TeV-PeV, where solar magnetic fields can be ignored. We also consider the leptonic gamma-ray halo, taking into account electrons from local pulsars. With Fermi and soon HAWC & LHAASO observations, our results provide new insights on local cosmic rays, solar magnetic fields, and solar dark matter studies. BZ is supported by OSU Fowler Fellowship.

2014-11-01

This study sought to document current refractive services in the northern and central regions of Ghana as a first step toward evidence-based planning of refractive services. A descriptive cross-sectional survey was carried out in health facilities in the northern and central regions of Ghana, which provided eye-care services. A semi-structured questionnaire was administered to gather information on each facility type, human resources providing refractive services, assessment of refraction and spectacle dispensing output and provider barriers to the services. Current outputs of refraction in the northern and central regions were 0.5 and 1.2 per cent of the estimated refractive needs, respectively. Spectacle dispensing services were below the outputs of refraction. Lack of equipment (36.8 per cent) and cost of providing spectacles frames (31.6 per cent), were identified as the main barriers to providing refractive services. The provision of refractive services in the study regions was inadequate. Lack of infrastructure and inadequate human resource were the major reasons for the limited service provision. This should be considered for planning refractive services in the study regions and Ghana as a whole. © 2014 The Authors.

The influence of a novel simulated learning environment upon student clinical subjective refraction performance: A pilot study.

PubMed

Woodman-Pieterse, Emily C; De Souza, Neilsen J; Vincent, Stephen J

2016-07-01

Optometry students are taught the process of subjective refraction through lectures and laboratory-based practicals before progressing to supervised clinical practice. Simulated leaning environments (SLEs) form part of an emerging technology used in a range of health disciplines; however, there is limited evidence regarding the effectiveness of clinical simulators as educational tools. Forty optometry students (20 fourth year and 20 fifth year) were assessed twice by a qualified optometrist (two examinations separated by four to eight weeks), while completing a monocular non-cycloplegic subjective refraction on the same patient with an unknown refractive error, simulated using contact lenses. Half of the students were granted access to an online simulated learning environment, The Brien Holden Vision Institute (BHVI) Virtual Refractor, and the remaining students formed a control group. The primary outcome measures at each visit were; accuracy of the clinical refraction compared to a qualified optometrist and relative to the Optometry Council of Australia and New Zealand (OCANZ) subjective refraction examination criteria. Secondary measures of interest included descriptors of student SLE engagement, student self-reported confidence levels and correlations between performance in the simulated and real-world clinical environment. Eighty per cent of students in the intervention group interacted with the simulated learning environment (for an average of 100 minutes); however, there was no correlation between measures of student engagement with the BHVI Virtual Refractor and speed or accuracy of clinical subjective refractions. Fifth year students were typically more confident and refracted more accurately and more quickly than fourth year students. A year group by experimental group interaction (p = 0.03) was observed for accuracy of the spherical component of refraction and post hoc analysis revealed that less experienced students exhibited greater gains in clinical accuracy following exposure to the SLE intervention. Short-term exposure to a SLE can positively influence clinical subjective refraction outcomes for less experienced optometry students and may be of benefit in increasing the skills of novice refractionists to levels appropriate for commencing supervised clinical interactions. © 2016 Optometry Australia.

A survey of UK optometry trainees' smoking cessation training.

2016-07-01

Smoking is a risk factor for a number of eye conditions, including age-related macular degeneration, cataracts and thyroid eye disease. Smoking cessation interventions have been shown to be highly cost-effective when delivered by a range of healthcare professionals. Optometrists are well placed to deliver smoking cessation advice to a wide population of otherwise healthy smokers. Yet optometrists remain a relatively neglected healthcare professional group in smoking cessation research and policy. Surveys of UK medical/nursing schools and of optometrists' training internationally demonstrate significant deficits in current curricular coverage regarding smoking cessation. This study aimed to identify the extent of smoking cessation training in UK optometry trainees' undergraduate and pre-registration training. All undergraduate optometry schools in the UK (n = 9) were invited to participate in a web-based survey of their curricular coverage and assessment related to smoking cessation, and of perceived barriers to delivering smoking cessation training. A content analysis of the College of Optometrists Scheme for Registration Trainee Handbook 2014 was conducted to identify competence indicators related to smoking cessation. Nine undergraduate optometry schools (100%) responded to the survey. The majority reported dedicating limited hours (0-3) to teaching smoking cessation, and predominantly focused on teaching the harmful effects of smoking (89%). Only one school provides practical skills training for delivering evidence-based smoking cessation interventions, including very brief advice. The majority of schools (78%) reported that they did not formally examine students on their knowledge or skills for supporting smoking cessation, and rated confidence in their graduates' abilities to deliver smoking cessation interventions as 'poor' (78%). Lack of knowledge amongst staff was identified as the key barrier to teaching about smoking cessation support. The pre-registration competency framework does not include any competence indicators related to providing support for quitting smoking. There are substantial gaps in the current curricula of UK optometry training, particularly regarding practical skills for supporting smoking cessation. Increased curricular coverage of these issues is essential to ensure trainee optometrists are adequately trained and competent in supporting patients to quit smoking. © 2016 The Authors.

Balancing patient care and student education: learning to deliver bad news in an optometry teaching clinic.

PubMed

Spafford, Marlee M; Schryer, Catherine F; Creutz, Stefan

2009-05-01

Learning to counsel patients in a teaching clinic or hospital occurs in the presence of the competing agendas of patient care and student education. We wondered about the challenges that these tensions create for clinical novices learning to deliver bad news to patients. In this preliminary study, we audio-taped and transcribed the interviews of seven senior optometry students and six optometrist instructors at a Canadian optometry teaching clinic. The participants described their experiences in learning to deliver bad news. Using a grounded theory approach, our analysis was informed by situated learning and activity theory. Optometry students received formal classroom training regarding how to deliver bad news, including exposure to the medically-based six-step SPIKES protocol (Baile et al. The Oncologist, 5, 302-311, 2000). Yet, application of this protocol to the teaching clinic was limited by the lack of exposure most instructors had received to this strategy. Determinants of the students' complex learning process during their clinical apprenticeship, included: (i) knowing one's place, (ii) knowing one's audience, (iii) knowing through feedback, and (iv) knowing who speaks. The experiences of these participants pointed toward the need for: (1) more instructional "scaffolding" (Bruner and Sherwood Play: Its role in development and evolution, p. 280, 1976) in the clinical setting when the learning task is complex, and (2) explicit discussions about the impacts that unfold when the activities of patient care and student education overlap. We reflect on the possible consequences to student education and patient care in the absence of these changes.

To compare spectacles bought online with spectacles from optometry practices. Thirty-three participants consisting of single vision spectacle wearers with either a low (N = 12, mean age 34 ± 14 years) or high prescription (N = 11, mean age 28 ± 9 years) and 10 presbyopic participants (mean age 59 ± 4 years) wearing progressive addition lenses (PALs) purchased 154 pairs of spectacles online and 154 from UK optometry practices. The spectacles were compared via participant-reported preference, acceptability, and safety; the assessment of lens, frame, and fit quality; and the accuracy of the lens prescriptions to international standard ISO 21987:2009. Participants preferred the practice spectacles (median ranking 4th, IQR 1-6) more than online (6th, IQR 4-8; Mann-Whitney U = 7345, p < 0.001) and practice PALs (median ranking 2nd, IQR 1-4) were particularly preferred (online 6.5th, IQR 4-9, Mann-Whitney U = 455, p < 0.001). Of those deemed unacceptable and unsafe, significantly more were bought online (unacceptable: online 43/154 vs. practice 15/154, Fisher's exact p = 0.0001; unsafe: online 14/154 vs. practice 5/154, Fisher's exact p = 0.03). Participants preferred spectacles from optometry practice rather than those bought online, despite lens quality and prescription accuracy being similar. A greater number of online spectacles were deemed unsafe or unacceptable because of poor spectacle frame fit, poor cosmetic appearance, and inaccurate optical centration. This seems particularly pertinent to PAL lenses, which are known to increase falls risk. Recommendations are made to improve both forms of spectacle provision.

Final report of “A Detailed Study of the Physical Mechanisms Controlling CO2-Brine Capillary Trapping in the Subsurface” (University of Arizona, DE-SC0006696)

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schaap, Marcel G.

Carbon capture and storage (CCS) of carbon dioxide emissions generated by production or combustion of fossil fuels is a technologically viable means to reduce the build-up of CO2 in the atmosphere and oceans. Using advantages of scale and location, CCS is particularly suitable for large point sources near ubiquitous deep saline aquifers, depleted gas reservoirs, or at production reservoirs for enhanced oil recovery (EOR). In the BES-funded research project, Oregon State University (OSU) carried out capillary trapping experiments with proxy fluids that mimic the properties of the scCO2/brine system under ambient temperatures and pressures, and successfully developed a unique andmore » novel x-ray compatible, high-pressure, elevated temperature setup to study the scCO2/brine system under challenging reservoir conditions. Both methodologies were applied to a variety of porous media, including synthetic (glass bead) and geologic (Bentheimer sandstone) materials. The University of Arizona (UA) developed pore-scale lattice Boltzmann (LB) models which are able to handle the experimental conditions for proxy fluids, as well as the scCO2/brine system, that are capable of simulating permeability in volumes of tens of millions of fluid elements. We reached the following summary findings (main institute indicated): 1. (OSU/UA) To understand capillary trapping in a multiphase fluid-porous medium system, the system must be analyzed from a pore-scale force balance perspective; trapping can be enhanced by manipulating wetting and nonwetting phase fluid properties. 2. (OSU) Pore-scale fluid connectivity and topology has a clear and direct effect on nonwetting phase capillary trapping efficiency. 3. (OSU) Rock type and flow regime also have a pronounced effects on capillary trapping. 4. (OSU/UA) There is a predictable relationship between NWP connectivity and NWP saturation, which allows for development of injection strategies that optimize trapping. The commonly used Land model (Land, 1968) does not predict amount of trapped NWP accurately. 5. (UA) There are ambiguities regarding the segmentation of large-volume gray-scale CT data into pore-volumes suitable for pore-scale modeling. Simulated permeabilities vary by three orders of magnitude and do not resemble observed values very well. Small-volume synchrotron-based CT data (such as produced by OSU) does not suffer significantly from segmentation ambiguities. 6. (UA) A standard properly parameterized Shan-Chen model LB model is useful for simulating porous media with proxy fluids as well as the scCO2/brine system and produces results that are consistent with tomographic observations. 7. (UA) A LB model with fluid-interactions defined by a (modified) Peng-Robinson Equation of State is able to handle the scCO2/brine system with variable solid phase wettability. This model is numerically stable at temperatures between 0 and 250 °C and pressures between 3 and 50 MPa, and produces appropriate densities above the critical point of CO2 and exhibits three-phase separation below. Based on above findings OSU and UA have proposed continued experimentation and pore-scale modeling of the scCO2/brine system. The reported research has extensively covered capillary trapping using proxy fluids, but due to limited beam-time availability we were unable to apply our high-pressure CO2 setup to sufficient variation in fluid properties, and initial scCO2 connectivity. New data will also allow us to test, calibrate and apply our LB models to reservoir conditions beyond those that are currently feasible experimentally. Such experiments and simulations will also allow us to provide information how suitable proxy fluids are for the scCO2/brine system. We believe it would be worthwhile to pursue the following new research questions: 1. What are the fundamental differences in the physics underlying capillary trapping at ambient vs. supercritical conditions? 2. Do newly developed pore-scale trapping interactions and relationships translate to continuum scales? A motivation for these questions was elaborated in “Capillary Trapping of Super-Critical CO2: Linking Pore and Continuum Scales to Verify new Relationships” that was submitted to DOE-BES in 2015.« less

[Research on whether atropine can be substituted by the powerful cycloplegic cyclopentolate].

For a long time, atropine eye ointment has been widely used as the cycloplegic for children's optometry in China, while internationally, cyclopentolate gutta is widely used as the first choice for cycloplegic. In recent years, 1% cyclopentolate hydrochloride ocular humor has been introduced to our country. This effective and powerful cycloplegic has already been paid close attention to by domestic pedo-ophthalmologists. According to a serious of studies both home and abroad on the therapeutic effects of the own control drugs, the cycloplegia effect of cyclopentolate is close to the atropine. Cyclopentolate can be widely used for the cycloplegia before optometry for the Chinese children. However, the effect of cyclopentolate is still not as good as atropine. So, for the children with farsightedness within 7 years old, all esotropia children, Am children, and children who suffer from decreased vision acuteness and needs to be excluded from accommodative myopia, atropine eye ointment should be routinely used for cycloplegia before optometry. In this article, we also discuss the medication dosage, medication method, possible drug adverse reactions of cyclopentolate humor ocular and the coping measures at the same time.

This study illustrates and quantifies the changes on corneal tissue between the paraffin-embedded and resin-embedded blocks and thus, selects a better target in investigational ophthalmology and optometry via light microscopy. Corneas of two cynomolgus monkeys (Macaca fascicularis) were used in this study. The formalin-fixed cornea was prepared in paraffin block via the conventional tissue processing protocol (4-day protocol) and stained with haematoxylin and eosin. The glutaraldehyde-fixed cornea was prepared in resin block via the rapid and modified tissue processing procedure (1.2-day protocol) and stained with toluidine blue. The paraffin-embedded sample exhibits various undesired tissue damage and artifact such as thinner epithelium (due to the substantial volumic extraction from the tissue), thicker stroma layer (due to the separation of lamellae and the presence of voids) and the distorted endothelium. In contrast, the resin-embedded corneal tissue has demonstrated satisfactory corneal ultrastructural preservation. The rapid and modified tissue processing method for preparing the resin-embedded is particularly beneficial to accelerate the microscopic evaluation in ophthalmology and optometry. PMID:22570589

1992-01-01

Inverse Synthetic Aperture Radar (ISAR) images for a 32 in long and 19 in wide model aircraft are documented. Both backscattered and bistatic scattered fields of this model aircraft were measured in the OSU-ESL compact range to obtain these images. The scattered fields of the target were measured for frequencies from 2 to 18 GHz with a 10 MHz increment and for full 360 deg azimuth rotation angles with a 0.2 deg step. For the bistatic scattering measurement, the compact range was used as the transmitting antenna; while, a broad band AEL double ridge horn was used as the receiving antenna. Bistatic angles of 90 deg and 135 deg were measured. Due to the size of the chamber and target, the receiving antenna was in the near field of the target; nevertheless, the image processing algorithm was valid for this case.

Learning From Where Students Look While Observing Simulated Physical Phenomena

2005-04-01

The Physics Education Research (PER) Group at the Ohio State University (OSU) has developed Virtual Reality (VR) programs for teaching introductory physics concepts. Winter 2005, the PER group worked with OSU's cognitive science eye-tracking lab to probe what features students look at while using our VR programs. We see distinct differences in the features students fixate on depending upon whether or not they have formally studied the related physics. Students who first make predictions seem to fixate more on the relevant features of the simulation than those who do not, regardless of their level of education. It is known that students sometimes perform an experiment and report results consistent with their misconceptions but inconsistent with the experimental outcome. We see direct evidence of one student holding onto misconceptions despite fixating frequently on the information needed to understand the correct answer. Future studies using these technologies may prove valuable for tackling difficult questions regarding student learning.

The development of a public optometry system in Mozambique: a Cost Benefit Analysis.

The economic burden of uncorrected refractive error (URE) is thought to be high in Mozambique, largely as a consequence of the lack of resources and systems to tackle this largely avoidable problem. The Mozambique Eyecare Project (MEP) has established the first optometry training and human resource deployment initiative to address the burden of URE in Lusophone Africa. The nature of the MEP programme provides the opportunity to determine, using Cost Benefit Analysis (CBA), whether investing in the establishment and delivery of a comprehensive system for optometry human resource development and public sector deployment is economically justifiable for Lusophone Africa. A CBA methodology was applied across the period 2009-2049. Costs associated with establishing and operating a school of optometry, and a programme to address uncorrected refractive error, were included. Benefits were calculated using a human capital approach to valuing sight. Disability weightings from the Global Burden of Disease study were applied. Costs were subtracted from benefits to provide the net societal benefit, which was discounted to provide the net present value using a 3% discount rate. Using the most recently published disability weightings, the potential exists, through the correction of URE in 24.3 million potentially economically productive persons, to achieve a net present value societal benefit of up to $1.1 billion by 2049, at a Benefit-Cost ratio of 14:1. When CBA assumptions are varied as part of the sensitivity analysis, the results suggest the societal benefit could lie in the range of $649 million to $9.6 billion by 2049. This study demonstrates that a programme designed to address the burden of refractive error in Mozambique is economically justifiable in terms of the increased productivity that would result due to its implementation.

2017-01-01

Validation of the Brain Injury Vision Symptom Survey (BIVSS), a self-administered survey for vision symptoms related to traumatic brain injury (TBI). A 28-item vision symptom questionnaire was completed by 107 adult subjects (mean age 42.1, 16.2 SD, range 18-75) who self-reported as having sustained mild-to-moderate TBI and two groups of reference adult subjects (first-year optometry students: mean age 23.2, 2.8 SD, range 20-39; and 71 third-year optometry students: mean age 26.0, 2.9 SD, range 22-42) without TBI. Both a Likert-style method of analysis with factor analysis and a Rasch analysis were used. Logistic regression was used to determine sensitivity and specificity. At least 27 of 28 questions were completed by 93.5% of TBI subjects, and all 28 items were completed by all of the 157 reference subjects. BIVSS sensitivity was 82.2% for correctly predicting TBI and 90.4% for correctly predicting the optometry students. Factor analysis identified eight latent variables; six factors were positive in their risk for TBI. Other than dry eye and double vision, the TBI patients were significantly more symptomatic than either cohort of optometry students by at least one standard deviation (p < 0.001). Twenty-five of 28 questions were within limits for creating a single-dimension Rasch scale. Nearly all of the adult TBI subjects were able to self-complete the BIVSS, and there was significant mean score separation between TBI and non-TBI groups. The Rasch analysis revealed a single dimension associated with TBI. Using the Likert method with the BIVSS, it may be possible to identify different vision symptom profiles with TBI patients. The BIVSS seems to be a promising tool for better understanding the complex and diverse nature of vision symptoms that are associated with brain injury.

ABSTRACT Purpose To compare spectacles bought online with spectacles from optometry practices. Methods Thirty-three participants consisting of single vision spectacle wearers with either a low (N = 12, mean age 34 ± 14 years) or high prescription (N = 11, mean age 28 ± 9 years) and 10 presbyopic participants (mean age 59 ± 4 years) wearing progressive addition lenses (PALs) purchased 154 pairs of spectacles online and 154 from UK optometry practices. The spectacles were compared via participant-reported preference, acceptability, and safety; the assessment of lens, frame, and fit quality; and the accuracy of the lens prescriptions to international standard ISO 21987:2009. Results Participants preferred the practice spectacles (median ranking 4th, IQR 1–6) more than online (6th, IQR 4–8; Mann-Whitney U = 7345, p < 0.001) and practice PALs (median ranking 2nd, IQR 1–4) were particularly preferred (online 6.5th, IQR 4–9, Mann-Whitney U = 455, p < 0.001). Of those deemed unacceptable and unsafe, significantly more were bought online (unacceptable: online 43/154 vs. practice 15/154, Fisher’s exact p = 0.0001; unsafe: online 14/154 vs. practice 5/154, Fisher’s exact p = 0.03). Conclusions Participants preferred spectacles from optometry practice rather than those bought online, despite lens quality and prescription accuracy being similar. A greater number of online spectacles were deemed unsafe or unacceptable because of poor spectacle frame fit, poor cosmetic appearance, and inaccurate optical centration. This seems particularly pertinent to PAL lenses, which are known to increase falls risk. Recommendations are made to improve both forms of spectacle provision. PMID:27536974

Factors affecting the academic performance of optometry students in Mozambique.

The Mozambique Eyecare Project is a higher education partnership for the development, implementation, and evaluation of a model of optometry training at UniLúrio in Mozambique. There are many composite elements to the development of sustainable eye health structures, and appropriate education for eye health workers remains a key determinant of successful eye care development. However, from the first intake of 16 students, only 9 students graduated from the program, whereas only 6 graduated from the second intake of 24 students. This low graduation rate is attributable to a combination of substandard academic performance and student dropout. The aim of this article was to identify factors affecting the academic performance of optometry students in Mozambique. Nine lecturers (the entire faculty) and 15 students (9 from the first intake and 6 from the second) were recruited to the study. Clinical competency assessments were carried out on the students, semistructured individual interviews were conducted with the course lecturers, and a course evaluation questionnaire was completed by students. The results were combined to understand the complexities surrounding the optometry student training and performance. One student out of nine from the first intake and three students out of six from the second were graded as competent in all the elements of the refraction clinical competency examination. Analysis of data from the interviews and questionnaire yielded four dominant themes that were viewed as important determinants of student refraction competencies: student learning context, teaching context, clinic conditions and assessment, and the existing operating health care context. The evaluations have helped the university and course partners to better structure the teaching and adapt the learning environments by recommending a preparatory year and a review of the curriculum and clinic structure, implementing more transparent entry requirements, increasing awareness of the program, and improving Internet infrastructure.

To provide screening services and obtain information on the eye health status and distribution of visual impairments in a refugee population of the sole refugee camp in Malawi. A general eye screening at Dzaleka refugee settlement camp was organized in November 2012. Final-year optometry students conducted detailed optometry examinations, including visual acuity (VA) assessment for near and distance, retinoscopy, and subjective refraction in cases with distance VA less than 6/12 or near VA less than N8, anterior and posterior segment evaluation. Their findings were then verified by an optometrist. The World Health Organization definition of vision impairment was followed, and the cause of vision impairment was determined at the end of each examination. Where possible, participants requiring refractive correction were provided spectacles free of cost. Of a total 635 participants examined, around one-half were male with 61% in the 16 to 49 years age group. The overall prevalence of presenting blindness, severe vision impairment, and vision impairment were 1.3% (95% confidence interval [95% CI], 0.5 to 2.4), 0.5% (95% CI, 0.0 to 1.1), and 3.6% (95% CI, 2.3 to 5.2), respectively. Overall vision impairment (VA <6/18) was present in 5.4% (95% CI, 3.6 to 7.1) of the participants. The principal causes of blindness, severe vision impairment, and vision impairment were cataracts, refractive errors, and corneal opacities, respectively; and more than 90% of the overall vision impairment was avoidable. Refractive errors and presbyopia were the most common morbidity, present in more than two-thirds of the participants examined. Only 5% of all the participants ever had a previous eye examination. The prevalence and causes of blindness and vision impairment in a refugee population are comparable with those of the general population. Lack of basic eye care services in the health center for refugees is a major concern. The health care facility in the settlement camp needs to be upgraded to provide comprehensive eye care including refractive care services.

With a higher life expectancy, there is an increased demand for hospital glaucoma services in the United Kingdom. The Cambridge community Optometry Glaucoma Scheme (COGS) was initiated in 2010, where new referrals for suspected glaucoma are evaluated by community optometrists with a special interest in glaucoma, with virtual electronic review and validation by a consultant ophthalmologist with special interest in glaucoma. 1733 patients were evaluated by this scheme between 2010 and 2013. Clinical assessment is performed by the optometrist at a remote site. Goldmann applanation tonometry, pachymetry, monoscopic colour optic disc photographs and automated Humphrey visual field testing are performed. A clinical decision is made as to whether a patient has glaucoma or is a suspect, and referred on or discharged as a false positive referral. The clinical findings, optic disc photographs and visual field test results are transmitted electronically for virtual review by a consultant ophthalmologist. The number of false positive referrals from initial referral into the scheme. Of the patients, 46.6% were discharged at assessment and a further 5.7% were discharged following virtual review. Of the patients initially discharged, 2.8% were recalled following virtual review. Following assessment at the hospital, a further 10.5% were discharged after a single visit. The COGS community-based glaucoma screening programme is a safe and effective way of evaluating glaucoma referrals in the community and reducing false-positive referrals for glaucoma into the hospital system. © 2014 Royal Australian and New Zealand College of Ophthalmologists.

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a hyperspectral imager on the Mars Reconnaissance Orbiter (MRO) spacecraft. CRISM consists of three subassemblies, a gimbaled Optical Sensor Unit (OSU), a Data Processing Unit (DPU), and the Gimbal Motor Electronics (GME). CRISM's objectives are (1) to map the entire surface using a subset of bands to characterize crustal mineralogy, (2) to map the mineralogy of key areas at high spectral and spatial resolution, and (3) to measure spatial and seasonal variations in the atmosphere. These objectives are addressed using three major types of observations. In multispectral mapping mode, with the OSU pointed at planet nadir, data are collected at a subset of 72 wavelengths covering key mineralogic absorptions and binned to pixel footprints of 100 or 200 m/pixel. Nearly the entire planet can be mapped in this fashion. In targeted mode the OSU is scanned to remove most along-track motion, and a region of interest is mapped at full spatial and spectral resolution (15-19 m/pixel, 362-3920 nm at 6.55 nm/channel). Ten additional abbreviated, spatially binned images are taken before and after the main image, providing an emission phase function (EPF) of the site for atmospheric study and correction of surface spectra for atmospheric effects. In atmospheric mode, only the EPF is acquired. Global grids of the resulting lower data volume observations are taken repeatedly throughout the Martian year to measure seasonal variations in atmospheric properties. Raw, calibrated, and map-projected data are delivered to the community with a spectral library to aid in interpretation.

Development of professional expertise in optometry.

Faucher, Caroline

2011-04-01

Development of professional expertise is the gradual transition from novice to expert within a profession. Studies on expertise in the profession of optometry have never been published. However, many studies have been performed in other health professions (e.g., nursing, medicine, physical therapy, occupational therapy). This report is an overview of the development of professional expertise that will highlight some applications for optometry. A 5-level scale of professional expertise development, divided into 2 parts, is described. The first part is the progression of students during their professional studies (novice, intermediate, competent). The second part is the professional development occurring during the practice years (advanced, expert). Personal and collective efforts are required to foster the progression toward expertise. Great interest for the profession, motivation, and deliberate practice are individual attitudes that help this progression. The "optometric community of practice," by means of university (professional) training, continuing education, and collaboration between colleagues, also contributes to this process. Professional development is an integral part of the Optometric Oath. Each clinical case is a potential learning experience contributing to one's professional development. Optometrists' attitudes are predominant factors in the progression from one level to another. Copyright © 2011 American Optometric Association. Published by Elsevier Inc. All rights reserved.

Webcams as a tool for teaching in Optometry training

NASA Astrophysics Data System (ADS)

Gargallo, A.; Arines, J.

2015-04-01

Clinical Optometry lab training is devoted to develop the students skills needed in eye healthcare professional practice. Nevertheless, students always find difficulties in the management of some optometric instruments and in the understanding of the evaluation techniques. Moreover, teachers also have problems in explaining the eye evaluation tests or making demonstrations of instruments handling. In order to facilitate the learning process, webcams adapted to the optometric devices represent a helpful and useful tool. In this work we present the use of webcams in some of the most common clinical test in Optometry as ocular refraction, colour vision test, eye health evaluation with slip-lamp, retinoscopy, ophthalmoscopy and contact lens fitting. Our experience shows that with this simple approach we can do things easier: show the instrument handling to all the students at the same time; take pictures or videos of different eye health conditions or exploratory routines for posterior visualization with all the students; recreate visual experience of the patient during optometric exam; simulate colour vision pathologies; increase the interactions between students allowing them to help and correct each other; and also record the final routine exam in order to make possible its revision with the students.

The aim was to describe the characteristics of the paediatric population attending the low vision clinic of the Eye and ENT Hospital, located in Shanghai, China. The clinical records of all the children attending the low vision clinic of Eye and ENT Hospital affiliated to Fudan University between January 1, 2009 and May 31, 2014 were retrospectively reviewed. The main data analysed were age, gender, education, visual demand, diagnosis, visual acuity and prescription of low vision aids. Of the 162 patients, 104 (64.20 per cent) were male. The age range of the study population was three to 20 years, with a mean of 10.73 ± 5.08 years. There were 43.21 per cent with moderate visual impairment, 26.54 per cent had severe visual impairment and 19.75 per cent were blind. The leading causes of visual impairment were congenital cataract (21.61 per cent), optic atrophy (14.20 per cent), macular dystrophy (11.73 per cent), nystagmus (9.88 per cent) and congenital glaucoma (9.26 per cent). The most frequently prescribed low vision devices for distant and near vision were binocular telescopes (23.57 per cent) and stand magnifiers (22.93 per cent), respectively. Young age (up to six years, 37.93 per cent), high cost (24.14 per cent), cosmetic reasons (17.24 per cent) and inconvenience (13.79 per cent) were the main reasons that children or parents refused to accept useful low vision aids. Congenital and hereditary diseases constituted the major causes of low vision in the study population. Strategies that make good-quality rehabilitation services available, affordable and accessible, especially in developing countries, will have the greatest impact on visual impairment. In China, both urban and rural, the coverage of low vision services should be strengthened. © 2016 The Authors. Clinical and Experimental Optometry © 2016 Optometry Australia.

Emergence of a rehabilitation medicine model for low vision service delivery, policy, and funding.

PubMed

Stelmack, Joan

2005-05-01

A rehabilitation medicine model for low vision rehabilitation is emerging. There have been many challenges to reaching consensus on the roles of each discipline (optometry, ophthalmology, occupational therapy, and vision rehabilitation professionals) in the service delivery model and finding a place in the reimbursement system for all the providers. The history of low vision, legislation associated with Centers for Medicare and Medicaid Services coverage for vision rehabilitation, and research on the effectiveness of low vision service delivery are reviewed. Vision rehabilitation is now covered by Medicare under Physical Medicine and Rehabilitation codes by some Medicare carriers, yet reimbursement is not available for low vision devices or refraction. Also, the role of vision rehabilitation professionals (rehabilitation teachers, orientation and mobility specialists, and low vision therapists) in the model needs to be determined. In a recent systematic review of the scientific literature on the effectiveness of low vision services contracted by the Agency for Health Care Quality Research, no clinical trials were found. The literature consists primarily of longitudinal case studies, which provide weak support for third-party funding for vision rehabilitative services. Providers need to reach consensus on medical necessity, treatment plans, and protocols. Research on low vision outcomes is needed to develop an evidence base to guide clinical practice, policy, and funding decisions.

Recent reports project a deficiency of veterinary pathologists, indicating a need to train highly qualified veterinary pathologists, particularly in academic veterinary medicine. The need to provide high-quality research training for veterinary pathologists has been recognized by the veterinary pathology training program of the Ohio State University (OSU) since its inception. The OSU program incorporates elements of both residency training and graduate education into a unified program. This review illustrates the components and structure of the training program and reflects on future challenges in training veterinary pathologists. Key elements of the OSU program include an experienced faculty, dedicated staff, and high-quality students who have a sense of common mission. The program is supported through cultural and infrastructure support. Financial compensation, limited research funding, and attractive work environments, including work-life balance, will undoubtedly continue to be forces in the marketplace for veterinary pathologists. To remain competitive and to expand the ability to train veterinary pathologists with research skills, programs must support strong faculty members, provide appropriate infrastructure support, and seek active partnerships with private industry to expand program opportunities. Shortages of trained faculty may be partially resolved by regional cooperation to share faculty expertise or through the use of communications technology to bridge distances between programs. To foster continued interest in academic careers, training programs will need to continue to evolve and respond to trainees' needs while maintaining strong allegiances to high-quality pathology training. Work-life balance, collegial environments that foster a culture of respect for veterinary pathology, and continued efforts to reach out to veterinary students to provide opportunities to learn about the diverse careers offered in veterinary pathology will pay long-term dividends for the future of the profession.

Optofluidic single-cell genome amplification was used to obtain genome sequences from sub-micron cells collected from the euphotic and mesopelagic zones of the northwestern Sargasso Sea. Plankton cells were visually selected and manually sorted with an optical trap, yielding 20 partial genome sequences representing seven bacterial phyla. Two organisms, E01-9C-26 (Gammaproteobacteria), represented by four single cell genomes, and Opi.OSU.00C, an uncharacterized Verrucomicrobia, were the first of their types retrieved by single cell genome sequencing and were studied in detail. Metagenomic data showed that E01-9C-26 is found throughout the dark ocean, while Opi.OSU.00C was observed to bloom transiently in the nutrient-depleted euphotic zone of the late spring and early summer. The E01-9C-26 genomes had an estimated size of 4.76–5.05 Mbps, and contained “O” and “W”-type monooxygenase genes related to methane and ammonium monooxygenases that were previously reported from ocean metagenomes. Metabolic reconstruction indicated E01-9C-26 are likely versatile methylotrophs capable of scavenging C1 compounds, methylated compounds, reduced sulfur compounds, and a wide range of amines, including D-amino acids. The genome sequences identified E01-9C-26 as a source of “O” and “W”-type monooxygenase genes related to methane and ammonium monooxygenases that were previously reported from ocean metagenomes, but are of unknown function. In contrast, Opi.OSU.00C genomes encode genes for catabolizing carbohydrate compounds normally associated with eukaryotic phytoplankton. This exploration of optofluidics showed that it was effective for retrieving diverse single-cell bacterioplankton genomes and has potential advantages in microbiology applications that require working with small sample volumes or targeting cells by their morphology.

Background: No pricing formula has been implemented from November 2002 to date in Sri Lanka. Therefore, we initiated a study in 2003 to determine the prices, availability and affordability of medicines in the private sector of Sri Lanka in the absence of a price control. Materials and Methods: The World Health Organization/Health Action International methodology was used. The study was conducted in retail pharmacies (Rajya Osu Sala) of State Pharmaceuticals Corporation (semigovernment) and privately owned retail pharmacies (n = 15) in 2003, 2006 and 2009 in a geographical area. Essential medicines (n = 28) were studied and, for each medicine, innovator, most sold generic and cheapest generic were monitored. The medicine’s median price was compared with the international reference prices (IRP) to obtain the median price ratio. The daily wage of the lowest-paid government worker was used to calculate affordability. Results: Innovators were five to six-times the IRP at privately owned pharmacies and four to seven-times at the Rajya Osu Sala. The prices of generics were ≤1 the IRP during 6 years in privately owned and Rajya Osu Sala pharmacies. Cheapest generics were high in availability (>80%) throughout the study period. Innovators cost more than a day’s wage of the lowest-paid government worker; in contrast, generics were always less than one day’s wage. There seems to be no difference in affordability between privately owned or semigovernment pharmacies. Conclusion: In Sri Lanka, generic medicines have effective pricing and are available and affordable. No drastic changes in prices of medicine in the private sector were observed over the 6 years despite removal of price control. PMID:21455424

Stresses due to Squeeze Flow between Particles Surrounded by an Electrolyte Solution with Application to Lithium-Ion Batteries

NASA Astrophysics Data System (ADS)

Conlisk, A. T.; Zhang, Cong

2013-11-01

Large stresses are induced during lithium-ion battery charging and discharging, termed intercalation and deintercalation stresses. Current models of the stresses in lithium-ion batteries in the literature seldom consider the influence of the interaction between the particles within the electrodes on the stress distribution. The particles within lithium-ion battery electrodes can undergo relative motion with relative velocities of different magnitudes and directions. One important mode of motion manifests itself as two particles approaching each other. The interaction is mediated by the electrolyte between the particles. The relative motion of the particles induces significant pressures and the primary objective of this work is to propose a source of mechanical stresses as a consequence of the dynamic squeezing motion as opposed to a static environment considered in the battery literature. Other applications in the biomedical field are also discussed.

This report describes the results of the first year of a research project performed by the Ohio State University ElectroScience Laboratory (OSU/ESL) for the Naval Weapons Center (NWC). The goal of this project is to explore the use of the polarization properties of the signal scattered from a radar target for the purpose of radar target identification. Various radar target identification algorithms were applied to the case of a full polarization coherent radar system, and were tested using a specific data base and noise model. The data base used to test the performance of the radar target identification algorithms developed here is a unique set of measurements made on scale models of aircraft. Measurements were made using the OSU/ESL Compact Radar Measurement Range. The range was operated in a broad-band (1-12 GHZ) mode and the full polarization matrix was measured. Calibrated values (amplitude and phase) of the RCS for the three polarization states were thus available. The polarization states are listed below.

Eye and vision problems have been reported to be more prevalent in rural than urban areas; and a large proportion of South Africans live in the rural areas. To investigate the opinions of South African optometry students about working in rural areas after completion of their training and to identify factors that may influence their decisions. This was a cross-sectional quantitative study using a survey instrument containing both closed and open-ended, semi-structured questions. Four hundred and thirty-eight students responded to the questionnaire (85.4% response rate). Overall, many of the respondents did not want to open their first (66%) or second practices (64.6%) in the rural areas. However, most respondents from rural backgrounds reported that they would open their first (77.2%) or second (79.4%) practice in the rural areas. The main reasons cited by the respondents for their unwillingness to work in the rural areas were financial concerns (81.2%), personal safety (80.1%) and poor living conditions (75.3%), with a significantly higher number (p < 0.05) being from urban respondents for the latter two issues only. Many students were not in favour of opening practices in rural areas, but were willing to work for the government or a non-governmental organisation after graduation. Efforts should be made to address financial incentives, safety and living conditions in the rural areas. The results of this study have implications for the future of availability and accessibility of eye care services to those living in the rural and remote areas of the country.

Evidence-based practice (EBP) is an essential component of good quality, patient-centered health care. This requires practitioners to acquire EBP skills and knowledge during undergraduate and continuing education. Evidence-based practice education exists in a range of health care disciplines, including optometry. Evidence-based practice education, however, depends on relevant skills and knowledge in educators. Courses and workshops exist for the development of EBP teaching skills in some areas of health care but not in optometry. Here, we describe a pilot workshop designed to enhance the teaching of EBP and to investigate the perspectives of optometric educators on EBP including their attitudes and perceived barriers to EBP and its teaching. Twenty-seven optometric educators including 8 facilitators participated. Of these, 14 were academics (including the 8 facilitators) and 13 were practitioners. Evidence-based practice attitudes were assessed using the Evidence-Based Practice Attitude Scale-50 with appropriate modifications for optometry. Workshop design incorporated strategies to trigger discussion among participants. A nominal group technique was used to identify, prioritize, and reach consensus on barriers to EBP. Although some participants expressed reservations about EBP, a common understanding of the contemporary definition of EBP emerged in educators. Thirty-five barriers to EBP were identified; "time" was selected in the top five barriers by most participants and attracted the highest total score, well above any other barrier (negative attitude to EBP, volume of evidence, integration with clinical practice, and lack of lifelong learning mind-set). Attitudes toward EBP were generally positive and negatively correlated with age and time since graduation, respectively. A group of optometrists and academics new to implementing education in EBP displayed positive attitudes to EBP but considered that its application and teaching could be significantly hindered by a lack of time to access and appraise the large volume of available research evidence in the field of eye care.

Genome Enabled Discovery of Carbon Sequestration Genes in Poplar

DOE Office of Scientific and Technical Information (OSTI.GOV)

Filichkin, Sergei; Etherington, Elizabeth; Ma, Caiping

2007-02-22

The goals of the S.H. Strauss laboratory portion of 'Genome-enabled discovery of carbon sequestration genes in poplar' are (1) to explore the functions of candidate genes using Populus transformation by inserting genes provided by Oakridge National Laboratory (ORNL) and the University of Florida (UF) into poplar; (2) to expand the poplar transformation toolkit by developing transformation methods for important genotypes; and (3) to allow induced expression, and efficient gene suppression, in roots and other tissues. As part of the transformation improvement effort, OSU developed transformation protocols for Populus trichocarpa 'Nisqually-1' clone and an early flowering P. alba clone, 6K10. Completemore » descriptions of the transformation systems were published (Ma et. al. 2004, Meilan et. al 2004). Twenty-one 'Nisqually-1' and 622 6K10 transgenic plants were generated. To identify root predominant promoters, a set of three promoters were tested for their tissue-specific expression patterns in poplar and in Arabidopsis as a model system. A novel gene, ET304, was identified by analyzing a collection of poplar enhancer trap lines generated at OSU (Filichkin et. al 2006a, 2006b). Other promoters include the pGgMT1 root-predominant promoter from Casuarina glauca and the pAtPIN2 promoter from Arabidopsis root specific PIN2 gene. OSU tested two induction systems, alcohol- and estrogen-inducible, in multiple poplar transgenics. Ethanol proved to be the more efficient when tested in tissue culture and greenhouse conditions. Two estrogen-inducible systems were evaluated in transgenic Populus, neither of which functioned reliably in tissue culture conditions. GATEWAY-compatible plant binary vectors were designed to compare the silencing efficiency of homologous (direct) RNAi vs. heterologous (transitive) RNAi inverted repeats. A set of genes was targeted for post transcriptional silencing in the model Arabidopsis system; these include the floral meristem identity gene (APETALA1 or AP1), auxin response factor gene (ETTIN), the gene encoding transcriptional factor of WD40 family (TRANSPARENTTESTAGLABRA1 or TTG1), and the auxin efflux carrier (PIN-FORMED2 or PIN2) gene. More than 220 transgenic lines of the 1st, 2nd and 3rd generations were analyzed for RNAi suppression phenotypes (Filichkin et. al., manuscript submitted). A total of 108 constructs were supplied by ORNL, UF and OSU and used to generate over 1,881 PCR verified transgenic Populus and over 300 PCR verified transgenic Arabidopsis events. The Populus transgenics alone required Agrobacterium co-cultivations of 124.406 explants.« less

The ever-expanding choice of ocular metrology and imaging equipment has driven research into the validity of their measurements. Consequently, studies of the agreement between two instruments or clinical tests have proliferated in the ophthalmic literature. It is important that researchers apply the appropriate statistical tests in agreement studies. Correlation coefficients are hazardous and should be avoided. The 'limits of agreement' method originally proposed by Altman and Bland in 1983 is the statistical procedure of choice. Its step-by-step use and practical considerations in relation to optometry and ophthalmology are detailed in addition to sample size considerations and statistical approaches to precision (repeatability or reproducibility) estimates.

Science Based Human Reliability Analysis: Using Digital Nuclear Power Plant Simulators for Human Reliability Research

NASA Astrophysics Data System (ADS)

Shirley, Rachel Elizabeth

Nuclear power plant (NPP) simulators are proliferating in academic research institutions and national laboratories in response to the availability of affordable, digital simulator platforms. Accompanying the new research facilities is a renewed interest in using data collected in NPP simulators for Human Reliability Analysis (HRA) research. An experiment conducted in The Ohio State University (OSU) NPP Simulator Facility develops data collection methods and analytical tools to improve use of simulator data in HRA. In the pilot experiment, student operators respond to design basis accidents in the OSU NPP Simulator Facility. Thirty-three undergraduate and graduate engineering students participated in the research. Following each accident scenario, student operators completed a survey about perceived simulator biases and watched a video of the scenario. During the video, they periodically recorded their perceived strength of significant Performance Shaping Factors (PSFs) such as Stress. This dissertation reviews three aspects of simulator-based research using the data collected in the OSU NPP Simulator Facility: First, a qualitative comparison of student operator performance to computer simulations of expected operator performance generated by the Information Decision Action Crew (IDAC) HRA method. Areas of comparison include procedure steps, timing of operator actions, and PSFs. Second, development of a quantitative model of the simulator bias introduced by the simulator environment. Two types of bias are defined: Environmental Bias and Motivational Bias. This research examines Motivational Bias--that is, the effect of the simulator environment on an operator's motivations, goals, and priorities. A bias causal map is introduced to model motivational bias interactions in the OSU experiment. Data collected in the OSU NPP Simulator Facility are analyzed using Structural Equation Modeling (SEM). Data include crew characteristics, operator surveys, and time to recognize and diagnose the accident in the scenario. These models estimate how the effects of the scenario conditions are mediated by simulator bias, and demonstrate how to quantify the strength of the simulator bias. Third, development of a quantitative model of subjective PSFs based on objective data (plant parameters, alarms, etc.) and PSF values reported by student operators. The objective PSF model is based on the PSF network in the IDAC HRA method. The final model is a mixed effects Bayesian hierarchical linear regression model. The subjective PSF model includes three factors: The Environmental PSF, the simulator Bias, and the Context. The Environmental Bias is mediated by an operator sensitivity coefficient that captures the variation in operator reactions to plant conditions. The data collected in the pilot experiments are not expected to reflect professional NPP operator performance, because the students are still novice operators. However, the models used in this research and the methods developed to analyze them demonstrate how to consider simulator bias in experiment design and how to use simulator data to enhance the technical basis of a complex HRA method. The contributions of the research include a framework for discussing simulator bias, a quantitative method for estimating simulator bias, a method for obtaining operator-reported PSF values, and a quantitative method for incorporating the variability in operator perception into PSF models. The research demonstrates applications of Structural Equation Modeling and hierarchical Bayesian linear regression models in HRA. Finally, the research demonstrates the benefits of using student operators as a test platform for HRA research.

Oklahoma Center for High Energy Physics (OCHEP)

DOE Office of Scientific and Technical Information (OSTI.GOV)

Nandi, S; Strauss, M J; Snow, J

2012-02-29

The DOE EPSCoR implementation grant, with the support from the State of Oklahoma and from the three universities, Oklahoma State University, University of Oklahoma and Langston University, resulted in establishing of the Oklahoma Center for High Energy Physics (OCHEP) in 2004. Currently, OCHEP continues to flourish as a vibrant hub for research in experimental and theoretical particle physics and an educational center in the State of Oklahoma. All goals of the original proposal were successfully accomplished. These include foun- dation of a new experimental particle physics group at OSU, the establishment of a Tier 2 computing facility for the Largemore » Hadron Collider (LHC) and Tevatron data analysis at OU and organization of a vital particle physics research center in Oklahoma based on resources of the three universities. OSU has hired two tenure-track faculty members with initial support from the grant funds. Now both positions are supported through OSU budget. This new HEP Experimental Group at OSU has established itself as a full member of the Fermilab D0 Collaboration and LHC ATLAS Experiment and has secured external funds from the DOE and the NSF. These funds currently support 2 graduate students, 1 postdoctoral fellow, and 1 part-time engineer. The grant initiated creation of a Tier 2 computing facility at OU as part of the Southwest Tier 2 facility, and a permanent Research Scientist was hired at OU to maintain and run the facility. Permanent support for this position has now been provided through the OU university budget. OCHEP represents a successful model of cooperation of several universities, providing the establishment of critical mass of manpower, computing and hardware resources. This led to increasing Oklahoma's impact in all areas of HEP, theory, experiment, and computation. The Center personnel are involved in cutting edge research in experimental, theoretical, and computational aspects of High Energy Physics with the research areas ranging from the search for new phenomena at the Fermilab Tevatron and the CERN Large Hadron Collider to theoretical modeling, computer simulation, detector development and testing, and physics analysis. OCHEP faculty members participating on the D0 collaboration at the Fermilab Tevatron and on the ATLAS collaboration at the CERN LHC have made major impact on the Standard Model (SM) Higgs boson search, top quark studies, B physics studies, and measurements of Quantum Chromodynamics (QCD) phenomena. The OCHEP Grid computing facility consists of a large computer cluster which is playing a major role in data analysis and Monte Carlo productions for both the D0 and ATLAS experiments. Theoretical efforts are devoted to new ideas in Higgs bosons physics, extra dimensions, neutrino masses and oscillations, Grand Unified Theories, supersymmetric models, dark matter, and nonperturbative quantum field theory. Theory members are making major contributions to the understanding of phenomena being explored at the Tevatron and the LHC. They have proposed new models for Higgs bosons, and have suggested new signals for extra dimensions, and for the search of supersymmetric particles. During the seven year period when OCHEP was partially funded through the DOE EPSCoR implementation grant, OCHEP members published over 500 refereed journal articles and made over 200 invited presentations at major conferences. The Center is also involved in education and outreach activities by offering summer research programs for high school teachers and college students, and organizing summer workshops for high school teachers, sometimes coordinating with the Quarknet programs at OSU and OU. The details of the Center can be found in http://ochep.phy.okstate.edu.« less

Correlation among auto-refractor, wavefront aberration, and subjective manual refraction

NASA Astrophysics Data System (ADS)

Li, Qi; Ren, Qiushi

2005-01-01

Three optometry methods which include auto-refractor, wavefront aberrometer and subjective manual refraction were studied and compared in measuring low order aberrations of 60 people"s 117 normal eyes. Paired t-test and linear regression were used to study these three methods" relationship when measuring myopia with astigmatism. In order to make the analysis more clear, we divided the 117 normal eyes into different groups according to their subjective manual refraction and redid the statistical analysis. Correlations among three methods show significant in sphere, cylinder and axis in all groups, with sphere"s correlation coefficients largest(R>0.98, P<0.01) and cylinder"s smallest (0.900.01). Auto-refractor had significant change from the other two methods when measuring cylinder (P<0.01). The results after grouping differed a little from the analysis among total people. Although three methods showed significant change from each other in certain parameters, the amplitude of these differences were not large, which indicated that the coherence of auto-refractor, wavefront aberrometer and subjective refraction is good. However, we suggested that wavefront aberration measurement could be a good starting point of optometry, subjective refraction is still necessary for refinement.

Large collaborative centers are a common model for accomplishing integrated environmental health research. These centers often include various types of scientific domains (e.g., chemistry, biology, bioinformatics) that are integrated to solve some of the nation's key economic or public health concerns. The Superfund Research Center (SRP) at Oregon State University (OSU) is one such center established in 2008 to study the emerging health risks of polycyclic aromatic hydrocarbons while using new technologies both in the field and laboratory. With outside collaboration at remote institutions, success for the center as a whole depends on the ability to effectively integrate data across all research projects and support cores. Therefore, the OSU SRP center developed a system that integrates environmental monitoring data with analytical chemistry data and downstream bioinformatics and statistics to enable complete "source-to-outcome" data modeling and information management. This article describes the development of this integrated information management system that includes commercial software for operational laboratory management and sample management in addition to open-source custom-built software for bioinformatics and experimental data management.

Analysis by RNA-RNA hybridization assay of intertypic rotaviruses suggests that gene reassortment occurs in vivo.

PubMed Central

Midthun, K; Valdesuso, J; Hoshino, Y; Flores, J; Kapikian, A Z; Chanock, R M

1987-01-01

Antigenic characterization of human and animal rotaviruses by the plaque reduction neutralization assay has shown the existence of naturally occurring intertypes. Antiserum to M37, a rotavirus strain isolated from an asymptomatic neonate, neutralizes both Wa and ST3 strains, which are classified as serotype 1 and serotype 4 human rotaviruses, respectively. Likewise, antiserum to SB-1A, a porcine rotavirus, neutralizes rotavirus strains belonging to serotype 4 or 5. Plaque reduction neutralization assay of reassortant rotaviruses produced in vitro from these intertypes indicates that these viruses share one antigenically related outer capsid protein, VP3, with one serotype and another antigenically related outer capsid protein, VP7, with the other serotype. Thus, M37 is related to ST3 on the basis of its fourth-gene product, VP3, and to Wa on the basis of its ninth-gene product, VP7, whereas SB-1A is related to Gottfried (serotype 4 porcine rotavirus) via VP7 and to OSU (serotype 5 porcine rotavirus) via VP3. RNA-RNA hybridization studies revealed a high degree of homology between the VP3 or VP7 gene segments responsible for shared serotype specificity. Thus, the fourth gene segments of M37 and ST3 were highly homologous, while M37 and Wa had homology between their ninth gene segments. SB-1A and Gottfried were homologous not only with respect to the ninth gene but had complete homology in all other genes except the fourth gene. The fourth gene of SB-1A was highly homologous with the fourth gene of OSU. These observations suggested that SB-1A was a naturally occurring reassortant between Gottfried-like and OSU-like porcine rotavirus strains. Our observations also suggested that intertypes may result from genetic reassortment in nature. Images PMID:3029162

Barriers to use of refractive services in Mozambique.

PubMed

Thompson, Stephen; Naidoo, Kovin; Gonzalez-Alvarez, Carmen; Harris, Geoff; Chinanayi, Farai; Loughman, James

2015-01-01

Uncorrected refractive error remains a leading cause of visual impairment (VI) across the globe with Mozambique being no exception. The establishment of an optometry profession in Mozambique that is integrated into the public health system denotes significant progress with refractive services becoming available to the population. As the foundations of a comprehensive refractive service have now been established, this article seeks to understand what barriers may limit their uptake by the general population and inform decision making on improved service delivery. A community-based cross-sectional study using two-stage cluster sampling was conducted. Participants with VI were asked to identify barriers that were reflective of their experiences and perceptions of accessing refractive services. A total of 4601 participants were enumerated from 76 clusters in Nampula, Mozambique. A total of 1087 visually impaired participants were identified (884 with near and 203 with distance impairment). Cost was the most frequently cited barrier, identified by more than one in every two participants (53%). Other barriers identified included lack of felt need (20%), distance to travel (15%), and lack of awareness (13%). In general, no significant influence of sex or type of VI on barrier selection was found. Location had a significant impact on the selection of several barriers. Pearson χ analysis indicated that participants from rural areas were found to feel disadvantaged regarding the distance to services (p ≤ 0.001) and adequacy of hospital services (p = 0.001). For a comprehensive public sector refractive service to be successful in Mozambique, those planning its implementation must consider cost and affordability. A clear strategy for overcoming lack of felt need will also be needed, possibly in the form of improved advocacy and health promotion. The delivery of refractive services in more remote rural areas merits careful and comprehensive consideration.

Access to low-vision rehabilitation services: barriers and enablers.

PubMed

Matti, Albert I; Pesudovs, Konrad; Daly, Andrew; Brown, Margaret; Chen, Celia S

2011-03-01

The current mismatch between the need for and uptake of low-vision services has been attributed to various barriers including different service delivery models and referral pathways. This study evaluates the referral pathway and low-vision service provision of the Royal Society for the Blind (RSB) in South Australia. All new referrals from the 2008-2009 financial year to the RSB were reviewed. Initially, patients were contacted by a triage officer within one week of referral. Initial appointments were made in the Low Vision Clinic with a multidisciplinary team. Reasons for declining the appointment or non-attendance were tracked via telephone. There were 1116 patients referred over a 12-month period and 1082 (97 per cent) were reviewed in the Low Vision Clinic. Most attendees (92 per cent) lived within 50 kilometres of the clinic. There were 34 referred patients, who declined or did not attend the assessment. All non-attendees also lived within 50 kilometres of the Low Vision Centre. Concurrent major health problems (27 per cent) and patients not feeling the need for low-vision rehabilitation (27 per cent) were the most common reasons for not accessing the service. Only 125 patients (11.6 per cent) accessed volunteer transport services and only 24 patients (2.2 per cent) needed an interpreter service. The attendance rate is significantly higher than in other published studies. The distance to travel or transport difficulties were not significant barriers. Patient perception that either the service was not required or would not help them was the main barrier. The referral and triage process appeared to be a major enabler of low-vision service uptake. © 2010 The Authors. Clinical and Experimental Optometry © 2010 Optometrists Association Australia.

Model of the Human Eye Based on ABCD Matrix

NASA Astrophysics Data System (ADS)

González, G. Díaz; Castillo, M. David Iturbe

2008-04-01

At the moment several models of the human eye exist, nevertheless the gradient index models of the human lens (crystalline) have received little attention in optometry and vision sciences, although they consider how the refractive index and the refracting power can change with the accommodation. On the other hand, in study fields like ophthalmology and optometry, exist cases where there is a lack of information about the factors that influence the change of refractive power and therefore the focal length of the eye. By such reason, in this paper we present a model of the human eye based on the ABCD matrix in order to describe the propagation of light rays, that can be understood by professional people in optics, ophthalmology and optometry, and the dispersions of the different ocular mediums are taken into account,. The aim of the model is to obtain data about the refractive power of the eye under different considerations, such as: changes in wavelength, radius of curvature and thicknesses of the ocular mediums. We present results of simulations in Matlab of our model, assuming that the object is punctual and is placed to a certain distance of the eye, and considering at the beginning to the crystalline like a medium with fixed refractive index, and after like a gradient lens. By means of graphs, we show the total refractive power of the eye and its form and type of dependence with respect to variations in radius of curvature and thicknesses of the cornea and crystalline, as well as variations in the thickness of the previous and later cameras.

2011-01-01

This cross-sectional study was designed to determine whether the academic performance of optometry undergraduates is influenced by enrollment status, learning style or gender. Three hundred and sixty undergraduates in all 3 years of the optometry degree course at Aston University during 2008-2009 were asked for their informed consent to participate in this study. Enrollment status was known from admissions records. An Index of Learning Styles (http://www4.nscu.edu/unity/lockers/users/f/felder/public/Learning-Styles.html) determined learning style preference with respect to four different learning style axes; active-reflective, sensing-intuitive, visual-verbal and sequential-global. The influence of these factors on academic performance was investigated. Two hundred and seventy students agreed to take part (75% of the cohort). 63% of the sample was female. There were 213 home non-graduates (entrants from the UK or European Union without a bachelor's degree or higher), 14 home graduates (entrants from the UK or European Union with a bachelor's degree or higher), 28 international non-graduates (entrants from outside the UK or European Union without a bachelor's degree or higher) and 15 international graduates (entrants from outside the UK or European Union with a bachelor's degree or higher). The majority of students were balanced learners (between 48% and 64% across four learning style axes). Any preferences were towards active, sensing, visual and sequential learning styles. Of the factors investigated in this study, learning styles were influenced by gender; females expressed a disproportionate preference for the reflective and visual learning styles. Academic performance was influenced by enrollment status; international graduates (95% confidence limits: 64-72%) outperformed all other student groups (home non graduates, 60-62%; international non graduates, 55-63%) apart from home graduates (57-69%). Our research has shown that the majority of optometry students have balanced learning styles and, from the factors studied, academic performance is only influenced by enrollment status. Although learning style questionnaires offer suggestions on how to improve learning efficacy, our findings indicate that current teaching methods do not need to be altered to suit varying learning style preferences as balanced learning styles can easily adapt to any teaching style (Learning Styles and Pedagogy in Post-16 Learning: A Systematic and Critical Review.

Accounting for ecosystem services in Life Cycle Assessment, Part II: toward an ecologically based LCA.

PubMed

Zhang, Yi; Baral, Anil; Bakshi, Bhavik R

2010-04-01

Despite the essential role of ecosystem goods and services in sustaining all human activities, they are often ignored in engineering decision making, even in methods that are meant to encourage sustainability. For example, conventional Life Cycle Assessment focuses on the impact of emissions and consumption of some resources. While aggregation and interpretation methods are quite advanced for emissions, similar methods for resources have been lagging, and most ignore the role of nature. Such oversight may even result in perverse decisions that encourage reliance on deteriorating ecosystem services. This article presents a step toward including the direct and indirect role of ecosystems in LCA, and a hierarchical scheme to interpret their contribution. The resulting Ecologically Based LCA (Eco-LCA) includes a large number of provisioning, regulating, and supporting ecosystem services as inputs to a life cycle model at the process or economy scale. These resources are represented in diverse physical units and may be compared via their mass, fuel value, industrial cumulative exergy consumption, or ecological cumulative exergy consumption or by normalization with total consumption of each resource or their availability. Such results at a fine scale provide insight about relative resource use and the risk and vulnerability to the loss of specific resources. Aggregate indicators are also defined to obtain indices such as renewability, efficiency, and return on investment. An Eco-LCA model of the 1997 economy is developed and made available via the web (www.resilience.osu.edu/ecolca). An illustrative example comparing paper and plastic cups provides insight into the features of the proposed approach. The need for further work in bridging the gap between knowledge about ecosystem services and their direct and indirect role in supporting human activities is discussed as an important area for future work.

Comparing Medical Ecology, Utilization, and Expenditures Between 1996-1997 and 2011-2012.

This study compared ecology (number of individuals using a service), utilization (number of services used), and expenditures (dollars spent) for various categories of medical services between primarily 1996-1997 and 2011-2012. A repeated cross-sectional study was performed using nationally representative data mainly from the 1996, 1997, 2011, and 2012 Medical Expenditure Panel Survey (MEPS). These data were augmented with the 2002-2003 MEPS as well as the 1999-2000 and 2011-2012 National Heath and Nutrition Examination Survey. Individuals (number per 1,000 people), utilization, and expenditures during an average month in 1996-1997 and 2011-2012 were determined for 15 categories of services. The number of individuals who used various medical services was unchanged for many categories of services (total, outpatient, outpatient physician, users of prescribed medications, primary care and specialty physicians, inpatient hospitalization, and emergency department). It was, however, increased for others (optometry/podiatry, therapy, and alternative/complementary medicine) and decreased for a few (dental and home health). The number of services used (utilization) largely mirrored the findings for individual use, with the exception of an increase in the number of prescribed medications and a decrease in number of primary care physician visits. There were large increases in dollars spent (expenditures) in every category with the exception of primary care physician and home health; the largest absolute increases were in prescribed medications, specialty physicians, emergency department visits, and likely inpatient hospitalizations. Although the number of individuals with visits during an average month and the total utilization of medical services were largely unchanged between the 2 time periods, total expenditures increased markedly. The increases in expenditure varied dramatically by category. © 2017 Annals of Family Medicine, Inc.

A telephone survey of low vision services in U.S. schools for the blind and visually impaired.

PubMed

Kran, Barry S; Wright, Darick W

2008-07-01

The scope of clinical low vision services and access to comprehensive eye care through U.S. schools for the blind and visually impaired is not well known. Advances in medicine and educational trends toward inclusion have resulted in higher numbers of visually impaired children with additional cognitive, motor, and developmental impairments enrolled in U.S. schools for the blind and visually impaired. The availability and frequency of eye care and vision education services for individuals with visual and multiple impairments at schools for the blind is explored in this report using data collected in a 24-item telephone survey from 35 of 42 identified U.S. schools for the blind. The results indicate that 54% of the contacted schools (19) offer clinical eye examinations. All of these schools provide eye care to the 6 to 21 age group, yet only 10 schools make this service available to children from birth to 3 years of age. In addition, two thirds of these schools discontinue eye care when the students graduate or transition to adult service agencies. The majority (94.7%) of eye care is provided by optometrists or a combination of optometry and ophthalmology, and 42.1% of these schools have an affiliation with an optometric institution. When there is a collaborative agreement, clinical services for students are available more frequently. The authors find that questions emerge regarding access to care, identification of appropriate models of care, and training of educational/medical/optometric personnel to meet the needs of a very complex patient population.

To evaluate and describe the pupil ruff changes and relationship to intraocular pressure, pseudoexfoliation syndrome and glaucoma status in an optometric population in New Zealand. Prospective cross-sectional survey of an optometric population. Six hundred and twenty subjects over 50 years old routinely attending the participating optometry practices. Exclusion criteria included previous intraocular surgery, ophthalmic laser, uveitis, angle closure and secondary glaucoma. Multicentre study involving 11 optometry practices in the Wellington region, New Zealand. The pupillary ruff and associated gonioscopy findings of study participants were graded based on the previously published Pupil Ruff Atrophy grading system. Parameters evaluated include pupillary ruff absence and abnormality, pseudoexfoliation material and trabecular meshwork pigmentation. Correlations between intereye Pupil Ruff Atrophy grading differences and inter-eye intraocular pressure and cup:disc ratio differences. Six hundred and twenty subjects were included, with a mean age of 62.2 ± 9.1 years and mean intraocular pressure of 14.8 ± 3.4 mmHg. Four hundred and fourteen (66.8%) had bilateral pupil ruff changes and 12 (1.5%) had pseudoexfoliation. Inter-eye intraocular pressure asymmetry was significantly correlated with amount of missing pupillary ruff (r = 0.111; P = 0.022) and trabecular meshwork pigmentation (r = 0.147; P = 0.002). Inter-eye cup:disc ratio asymmetry was not correlated with any of the Pupil Ruff Atrophy grading parameters. Asymmetry of pupillary ruff absence and trabecular meshwork pigmentation was correlated with intraocular pressure asymmetry (but not with cup:disc ratio asymmetry) in a general optometric population setting in New Zealand. © 2012 The Authors.

The practice of optometry: National Board of Examiners in Optometry survey of optometric patients.

PubMed

Soroka, Mort; Krumholz, David; Bennett, Amy

2006-09-01

A study commissioned by the National Board of Examiners in Optometry was designed to obtain information about patients seen in general practice. Providers completed an encounter form for patients seen during a 2-day sample. Data were obtained from 11,012 patients in rural, urban, and suburban environments from a diverse population of 480 optometrists representative of profession-wide practitioners in terms of geographic distribution and practice settings. Although practitioners were selected randomly, the response rate among those who were invited to participate was only 17.7%. Optometrists who specialized and did not classify themselves as general practitioners were excluded from the study. The study provides insights into the most common diagnostic and therapeutic procedures performed, medications prescribed, and referrals made in general practices. Seventy-one percent of all examinations were categorized as comprehensive, approximately 13% were because of disease, and 11% were for contact lens care. Almost 17% of all patients received a formal visual field test (Goldmann or automated). Refractive error was the most prevalent diagnosis, reflective of the ocular problems found in the general population, and systemic conditions were the second largest category. Although 12% of all patients were referred to an ophthalmologist for further care, other types of referrals were infrequent. Referrals to a primary care physician, laboratory, and imaging or for refractive surgery accounted for only 8% of all referrals. Ocular disease treatment was found to be an integral part of the optometrist's practice. Prescribing topical medications, both legend and "over-the-counter," was a primary treatment option. The most common medications prescribed were for glaucoma, with antibiotics, anti-inflammatory and anti-allergy drops making up the remainder, in descending order.

The Health and Social Security Act 1984 and the price of spectacles among corporate practices in the United Kingdom (1980-2007): a review.

PubMed

Calver, Richard

2010-03-01

The Health and Social Security Act 1984 deregulated certain aspects of optometry in the United Kingdom, including advertising and the supply of spectacles, in the hope that greater competition would reduce spectacle prices. The effects of this legislation are tested by plotting the mean prices of private spectacles purchased from corporate optometric practices, from 1980 to 2007. Historical evidence is used to gauge the effect on prices of other factors such as National Health Service (NHS) payments, sight test fees and pressure exerted by consumer organisations. The high prices in 1980 reduced markedly throughout the rest of the 1980s, remained low for most of the 1990s and rose between 1999 and 2003, before falling. Changes in price were associated with changes to the system of NHS payments and variations in private sight test fees, but prices have generally been lower since the deregulation of dispensing than they were before. Although the price of private spectacles remains heavily influenced by other factors, the deregulation of opticians' services has benefited the public by maintaining lower prices, as intended by proponents of the legislation.

1992-05-01

This topical report on Sulfur Control'' presents the results of work conducted by the Institute of Gas Technology (IGT), the Illinois Institute of Technology (IIT), and the Ohio State University (OSU) to develop three novel approaches for desulfurization that have shown good potential with coal and could be cost-effective for oil shales. These are (1) In-Bed Sulfur Capture using different sorbents (IGT), (2) Electrostatic Desulfurization (IIT), and (3) Microbial Desulfurization and Denitrification (OSU and IGT). The objective of the task on In-Bed Sulfur Capture was to determine the effectiveness of different sorbents (that is, limestone, calcined limestone, dolomite, and siderite)more » for capturing sulfur (as H{sub 2}S) in the reactor during hydroretorting. The objective of the task on Electrostatic Desulfurization was to determine the operating conditions necessary to achieve a high degree of sulfur removal and kerogen recovery in IIT's electrostatic separator. The objectives of the task on Microbial Desulfurization and Denitrification were to (1) isolate microbial cultures and evaluate their ability to desulfurize and denitrify shale, (2) conduct laboratory-scale batch and continuous tests to improve and enhance microbial removal of these components, and (3) determine the effects of processing parameters, such as shale slurry concentration, solids settling characteristics, agitation rate, and pH on the process.« less

Isolation and characterization of an equine rotavirus.

PubMed Central

Hoshino, Y; Wyatt, R G; Greenberg, H B; Kalica, A R; Flores, J; Kapikian, A Z

1983-01-01

A rotavirus, designated as the H-1 strain, was isolated from a diarrheic foal in primary African green monkey kidney cells and MA104 cells. This cell culture-adapted strain hemagglutinated erythrocytes of human group O, rhesus monkeys, guinea pigs, and sheep. It was found to be similar, if not identical, to porcine rotaviruses (strains OSU, EE, and A-580) by plaque reduction neutralization and hemagglutination inhibition tests, and, in addition, it was found to belong to subgroup 1. This equine rotavirus has an RNA electrophoretic migration pattern which was distinct from those of the three strains of porcine rotavirus. The serological relationship established by plaque reduction neutralization and hemagglutination inhibition tests between the equine (H-1) and porcine (OSU, EE, and A-580) rotaviruses is an example of a rotavirus of the same serotype being isolated from different species. The H-1 strain was distinct from four human rotavirus serotypes (Wa, DS-1, P, and St. Thomas 4) as well as from bovine rotavirus NCDV, simian rotavirus MMU18006, and canine rotavirus CU-1 by plaque reduction neutralization tests. This equine isolate (H-1) was found to be related antigenically to canine CU-1 and bovine NCDV rotaviruses in a one-way fashion by hemagglutination inhibition tests. Images PMID:6313746

Electronic Referrals and Digital Imaging Systems in Ophthalmology: A Global Perspective.

PubMed

Jeganathan, V Swetha E; Hall, H Nikki; Sanders, Roshini

2017-01-01

Ophthalmology departments face intensifying pressure to expedite sight-saving treatments and reduce the global burden of disease. The use of electronic communication systems, digital imaging, and redesigned service care models is imperative for addressing such demands. The recently developed Scottish Eyecare Integration Project involves an electronic referral system from community optometry to the hospital ophthalmology department using National Health Service (NHS) email with digital ophthalmic images attached, via a virtual private network connection. The benefits over the previous system include reduced waiting times, improved triage, e-diagnosis in 20% without the need for hospital attendance, and rapid electronic feedback to referrers. We draw on the experience of the Scottish Eyecare Integration Project and discuss the global applications of this and other advances in teleophthalmology. We focus particularly on the implications for management and screening of chronic disease, such as glaucoma and diabetic eye disease, and ophthalmic disease, such as retinopathy of prematurity where diagnosis is almost entirely and critically dependent on fundus appearance. Currently in Scotland, approximately 75% of all referrals are electronic from community to hospital. The Scottish Eyecare Integration Project is globally the first of its kind and unique in a national health service. Such speedy, safe, and efficient models of communication are geographically sensitive to service provision, especially in remote and rural regions. Along with advances in teleophthalmology, such systems promote the earlier detection of sight-threatening disease and safe follow-up of non-sight-threatening disease in the community.

A pilot quality assurance scheme for diabetic retinopathy risk reduction programmes.

PubMed

Garvican, L; Scanlon, P H

2004-10-01

We describe a pilot study of measurement of quality assurance targets for diabetic retinopathy screening and performance comparison between 10 existing services, in preparation for the roll-out of the national programme. In 1999 the UK National Screening Committee approved proposals for a national diabetic retinopathy risk reduction programme, including recommendations for quality assurance, but implementation was held pending publication of the National Service Framework for Diabetes. Existing services requested the authors to perform a pilot study of a QA scheme, indicating willingness to contribute data for comparison. Objectives and quality standards were developed, following consultation with diabetologists, ophthalmologists and retinal screeners. Services submitted 2001/2 performance data, in response to a questionnaire, for anonymization, central analysis and comparison. The 17 quality standards encompass all aspects of the programme from identification of patients to timeliness of treatment. Ten programmes took part, submitting all the data available. All returns were incomplete, but especially so from the optometry-based schemes. Eight or more services demonstrated they could reach the minimum level in only five of the 17 standards. Thirty per cent could not provide coverage data. All were running behind. Reasons for difficulties in obtaining data and/or failing to achieve standards included severe under-funding and little previous experience of QA. Information systems were limited and incompatible between diabetes and eye units, and there was a lack of co-ordinated management of the whole programme. Quality assurance is time-consuming, expensive and inadequately resourced. The pilot study identified priorities for local action. National programme implementation must involve integral quality assurance mechanisms from the outset.

Thompson, Stephen; Naidoo, Kovin; Gonzalez-Alvarez, Carmen; Harris, Geoff; Chinanayi, Farai; Loughman, James

2015-01-01

ABSTRACT Purpose Uncorrected refractive error remains a leading cause of visual impairment (VI) across the globe with Mozambique being no exception. The establishment of an optometry profession in Mozambique that is integrated into the public health system denotes significant progress with refractive services becoming available to the population. As the foundations of a comprehensive refractive service have now been established, this article seeks to understand what barriers may limit their uptake by the general population and inform decision making on improved service delivery. Methods A community-based cross-sectional study using two-stage cluster sampling was conducted. Participants with VI were asked to identify barriers that were reflective of their experiences and perceptions of accessing refractive services. A total of 4601 participants were enumerated from 76 clusters in Nampula, Mozambique. Results A total of 1087 visually impaired participants were identified (884 with near and 203 with distance impairment). Cost was the most frequently cited barrier, identified by more than one in every two participants (53%). Other barriers identified included lack of felt need (20%), distance to travel (15%), and lack of awareness (13%). In general, no significant influence of sex or type of VI on barrier selection was found. Location had a significant impact on the selection of several barriers. Pearson χ2 analysis indicated that participants from rural areas were found to feel disadvantaged regarding the distance to services (p ≤ 0.001) and adequacy of hospital services (p = 0.001). Conclusions For a comprehensive public sector refractive service to be successful in Mozambique, those planning its implementation must consider cost and affordability. A clear strategy for overcoming lack of felt need will also be needed, possibly in the form of improved advocacy and health promotion. The delivery of refractive services in more remote rural areas merits careful and comprehensive consideration. PMID:25379630

When people think about the effects of climate change, many will still picture that iconic lone polar bear clinging to a shrinking iceberg in Antarctica. But many don't realize that the impacts that we will face here at home could also be severe, directly affecting the food we eat, the health we have, and the natural environments we appreciate. To help better explain and ultimately localize those impacts for Great Lakes residents, 10 departments within Ohio State University partnered in 2009 to create the Global Change, Local Impact webinar series. The monthly series brings in experts from around the Great Lakes region to discuss issues and impacts we will encounter regionally as our climate changes. Originally designed as a small series for Ohioans, the series has broadened to focus on Great Lakes-related issues, with more than 4,500 attendees representing 500 organizations in governmental agencies, academia, non-profit groups, private industry, and the legislature from around the country. Over the past two years, the OSU Climate Team expanded its educational reach by partnering with external groups like the Centers for Disease Control and Prevention, Great Lakes Regional Water Program, National Oceanic and Atmospheric Administration, and the Great Lakes Sea Grant Network to help deliver the most knowledgeable experts and resources for each Great Lake-focused climate topic and archive those resources on its www.changingclimate.osu.edu web site. As a result of these collaborative efforts, participants say the webinars are one of their primary resources for climate-related research information in the region, with 80-90% polled saying they use this information as an unbiased resource to help not only understand how climate change could affect local concerns like public health, agriculture, and infrastructure, but what they in their vocations and daily lives can do to prepare for it. For scientists and practitioners, this series serves as the perfect low carbon venue to share climate research and response projects with a diverse group of individuals. For webinar attendees, real-time and recorded webinars provide access to current research data and the ability to interact with like-minded colleagues working to mitigate and adapt to regional impacts of climate change. This presentation will provide an overview of this ongoing project, as well as the available online climate resources and webinar survey results from the series.

BIOACCESSIBILITY TESTS ACCURATELY ESTIMATE ...

EPA Pesticide Factsheets

Hazards of soil-borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb-contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb acetate reference diet. Diets containing soil from five Pb-contaminated Superfund sites had relative bioavailabilities from 33%-63%, with a mean of about 50%. Treatment of two of the soils with P significantly reduced the bioavailability of Pb. The bioaccessibility of the Pb in the test soils was then measured in six in vitro tests and regressed on bioavailability. They were: the “Relative Bioavailability Leaching Procedure” (RBALP) at pH 1.5, the same test conducted at pH 2.5, the “Ohio State University In vitro Gastrointestinal” method (OSU IVG), the “Urban Soil Bioaccessible Lead Test”, the modified “Physiologically Based Extraction Test” and the “Waterfowl Physiologically Based Extraction Test.” All regressions had positive slopes. Based on criteria of slope and coefficient of determination, the RBALP pH 2.5 and OSU IVG tests performed very well. Speciation by X-ray absorption spectroscopy demonstrated that, on average, most of the Pb in the sampled soils was sorbed to minerals (30%), bound to organic matter 24%, or present as Pb sulfate 18%.

Comparison of CRISPR/Cas9 expression constructs for efficient targeted mutagenesis in rice.

PubMed

Mikami, Masafumi; Toki, Seiichi; Endo, Masaki

2015-08-01

The CRISPR/Cas9 system is an efficient tool used for genome editing in a variety of organisms. Despite several recent reports of successful targeted mutagenesis using the CRISPR/Cas9 system in plants, in each case the target gene of interest, the Cas9 expression system and guide-RNA (gRNA) used, and the tissues used for transformation and subsequent mutagenesis differed, hence the reported frequencies of targeted mutagenesis cannot be compared directly. Here, we evaluated mutation frequency in rice using different Cas9 and/or gRNA expression cassettes under standardized experimental conditions. We introduced Cas9 and gRNA expression cassettes separately or sequentially into rice calli, and assessed the frequency of mutagenesis at the same endogenous targeted sequences. Mutation frequencies differed significantly depending on the Cas9 expression cassette used. In addition, a gRNA driven by the OsU6 promoter was superior to one driven by the OsU3 promoter. Using an all-in-one expression vector harboring the best combined Cas9/gRNA expression cassette resulted in a much improved frequency of targeted mutagenesis in rice calli, and bi-allelic mutant plants were produced in the T0 generation. The approach presented here could be adapted to optimize the construction of Cas9/gRNA cassettes for genome editing in a variety of plants.

We sought to determine whether there are differences in health resource utilization among South Asian (SA), Chinese and White patients with newly diagnosed diabetes mellitus. We used province-wide administrative data from British Columbia, Canada (1997-2006) to determine proportion of patients with ≥2 visits/year for all outpatient and family physician (FP) visits, proportion of patients with at least one annual visit to specialists, ophthalmology/optometry and hospital admissions by ethnic group. There were 9529 South Asian, 14,084 Chinese and 143,630 White patients with newly diagnosed diabetes in the study. Over 90% of each of the ethnic groups visited their FP ≥2 visits/year. Chinese patients were less likely to visit FP, ophthalmology/optometrists and specialists compared to White patients. SA patients had fewer ophthalmology/optometry visits compared to White populations. White patients had higher rates of hospitalization. Although all groups had high proportion of patients with appropriate frequency of FP visits, other aspects of health care utilization varied significantly by ethnicity.

2014-07-01

Academic results depend strongly on the individual circumstances of students: background, motivation and aptitude. We think that academic activities conducted to increase motivation must be tuned to the special situation of the students. Main goal of this work is analyze the students in the first year of the Degree in Optics and Optometry in the University of Granada and the suitability of an activity designed for those students. Initial data were obtained from a survey inquiring about the reasons to choose this degree, their knowledge of it, and previous academic backgrounds. Results show that: 1) the group is quite heterogeneous, since students have very different background. 2) Reasons to choose the Degree in Optics and Optometry are also very different, and in many cases were selected as a second option. 3) Knowledge and motivations about the Degree are in general quite low. Trying to increase the motivation of the students we designed an academic activity in which we show different topics studied in the Degree. Results show that students that have been involved in this activity are the most motivated and most satisfied with their election of the degree.

Studies Related to the Oregon State University High Temperature Test Facility: Scaling, the Validation Matrix, and Similarities to the Modular High Temperature Gas-Cooled Reactor

DOE Office of Scientific and Technical Information (OSTI.GOV)

Richard R. Schultz; Paul D. Bayless; Richard W. Johnson

2010-09-01

The Oregon State University (OSU) High Temperature Test Facility (HTTF) is an integral experimental facility that will be constructed on the OSU campus in Corvallis, Oregon. The HTTF project was initiated, by the U.S. Nuclear Regulatory Commission (NRC), on September 5, 2008 as Task 4 of the 5 year High Temperature Gas Reactor Cooperative Agreement via NRC Contract 04-08-138. Until August, 2010, when a DOE contract was initiated to fund additional capabilities for the HTTF project, all of the funding support for the HTTF was provided by the NRC via their cooperative agreement. The U.S. Department of Energy (DOE) beganmore » their involvement with the HTTF project in late 2009 via the Next Generation Nuclear Plant project. Because the NRC interests in HTTF experiments were only centered on the depressurized conduction cooldown (DCC) scenario, NGNP involvement focused on expanding the experimental envelope of the HTTF to include steady-state operations and also the pressurized conduction cooldown (PCC). Since DOE has incorporated the HTTF as an ingredient in the NGNP thermal-fluids validation program, several important outcomes should be noted: 1. The reference prismatic reactor design, that serves as the basis for scaling the HTTF, became the modular high temperature gas-cooled reactor (MHTGR). The MHTGR has also been chosen as the reference design for all of the other NGNP thermal-fluid experiments. 2. The NGNP validation matrix is being planned using the same scaling strategy that has been implemented to design the HTTF, i.e., the hierarchical two-tiered scaling methodology developed by Zuber in 1991. Using this approach a preliminary validation matrix has been designed that integrates the HTTF experiments with the other experiments planned for the NGNP thermal-fluids verification and validation project. 3. Initial analyses showed that the inherent power capability of the OSU infrastructure, which only allowed a total operational facility power capability of 0.6 MW, is inadequate to permit steady-state operation at reasonable conditions. 4. To enable the HTTF to operate at a more representative steady-state conditions, DOE recently allocated funding via a DOE subcontract to HTTF to permit an OSU infrastructure upgrade such that 2.2 MW will become available for HTTF experiments. 5. Analyses have been performed to study the relationship between HTTF and MHTGR via the hierarchical two-tiered scaling methodology which has been used successfully in the past, e.g., APEX facility scaling to the Westinghouse AP600 plant. These analyses have focused on the relationship between key variables that will be measured in the HTTF to the counterpart variables in the MHTGR with a focus on natural circulation, using nitrogen as a working fluid, and core heat transfer. 6. Both RELAP5-3D and computational fluid dynamics (CD-Adapco’s STAR-CCM+) numerical models of the MHTGR and the HTTF have been constructed and analyses are underway to study the relationship between the reference reactor and the HTTF. The HTTF is presently being designed. It has ¼-scaling relationship to the MHTGR in both the height and the diameter. Decisions have been made to design the reactor cavity cooling system (RCCS) simulation as a boundary condition for the HTTF to ensure that (a) the boundary condition is well defined and (b) the boundary condition can be modified easily to achieve the desired heat transfer sink for HTTF experimental operations.« less

Comparison of the VISX wavescan and OPD-scan III with the subjective refraction.

Zhu, R; Long, K-L; Wu, X-M; Li, Q-D

2016-07-01

To compare the refractive errors measured by the VISX WaveScan, OPD-Scan III and the subjective refraction. The optometry accuracy of computer operated aberrometer used before refractive surgery has been debatable. Hence, a clear study on the role of such automated equipment in optometry is the need of the hour as compared to subjective refraction. Seventy-six patients (152 eyes) were recruited from January 2013 to December 2013. All patients were measured with subjective refraction by the phoropter (NIDEK, RT-5100), objective refraction by the WaveScan (AMO Company, USA), OPD-Scan III (Nidek Technologies, Japan). The sphere, cylinder, axis of the three methods were compared and analyzed. The diopter of sphere power measured by WaveScan was lower than that of the subjective refraction and the difference was 0.13 ± 0. 30D (t = 3. 753, p <0. 001). While the diopter of cylinder power was higher and the difference was 0.13 ±0.43D (t = 3. 664, p <0. 001). There was no significance for sphere, cylinder and spherical equivalent between OPD-Scan III and subjective refraction (p >0. 05). The value of the difference between WaveScan and subjective refraction was 5.87°±6.19°on average, while the difference between OPD-Scan III and subjective refraction was 3.82°±3.95°on average. The differences between the two were statistically significant (t =2. 817, p =0. 006). The results of sphere and cylinder measured by WaveScan and subjective refraction were different. As the latest integrated equipment, the Nidek OPD-Scan III gives a more accurate measurement of objective refraction when compared with subjective refraction. The latest Nidek OPD-Scan III may prove to be an useful tool for preoperative optometry deviation based on objective refraction.

Bakkum, Barclay W; Trachimowicz, Ruth

2015-11-01

The purposes of this study were to investigate the publication rates of presentations at the 2006 meeting of the American Academy of Optometry (AAO), differences in the publication rates of platform versus poster presentations, consistency of the meeting abstract compared with the full-length journal article, whether abstracts were clinical or basic science, and when and in which journals articles appeared. Abstracts were obtained directly from the AAO. Literature searches using PubMed and VisionCite were performed to locate peer-reviewed journal articles based on those abstracts. Whether the article was based on a poster or platform presentation, congruence of the information in the abstract and the article (i.e., authorship, title, methods, and conclusions), type of study (clinical or basic science), subject category, and journal and year in which the article appeared were recorded. We identified 518 proceeding abstracts, 108 of which ultimately were published between 2006 and 2013, giving an overall publication rate of 21%. Thirty-three percent of platform presentations eventually were published versus 18% of posters. Congruency showed that 17% of articles had the same title as the meeting abstract, 36% had the same authorship, and 53% had the same methods. Eighty-one percent of articles were clinical in nature, whereas 19% of them were basic science. Thirty-seven percent of articles dealt with the subjects of cornea and contact lenses. Articles were found in 39 different journals, with 34% of them appearing in Optometry and Vision Science. Eighty-eight percent of articles were published within 4 years after the meeting. The publication rate from the 2006 AAO meeting was 21%. Platform presentations were more likely to be published than posters. Congruency rates of abstracts to articles are lower than national meetings in other fields. The vast majority of articles were published within 4 years after the meeting.

Light and optics conceptual evaluation findings from first year optometry students

Thapa, Damber; Lakshminarayanan, Vasudevan

2014-07-01

The Light and Optics Conceptual Evaluation (LOCE) was developed to examine conceptual understanding of basic geometric and physical optics for the Active Learning in Optics and Photonics program administered by UNESCO. This 50 item test (46 multiple choice, 4 ray-tracing short answer) was administered to entering students in the Optometry professional degree (OD) program. We wanted to determine how much of the physics/optics concepts from undergraduate physics courses (a pre-requisite for entry to the OD program) were retained. In addition, the test was administered after the first year students had taken a required course in geometric and visual optics as part of their first semester courses. The LOCE was completed by two consecutive classes to the program in 2010 (n=89) and 2011 (n=84). The tests were administered the first week of the term and the test was given without any prior notice. In addition, the test was administered to the class of 2010 students after they had completed the course in geometric and visual optics. The means of the test were 22.1 (SD=4.5; range: 12-35) and 21.3(SD=5.1; range: 11-35) for the two entering classes. There was no statistical significance between the two classes (t-test, p<0.05). Similarly there was no difference between the scores in terms of gender. The post-course test (administered during the first week of the second term) showed a statistically significant improvement (mean score went from 22.1 to 31.1, a 35% improvement). It should be noted that both groups of students performed worse in questions related to physical optics as well as lens imaging, while scoring best in questions related to refraction and reflection. These data should be taken into consideration when designing optics curricula for optometry (and other allied health programs such as opticianry or ophthalmology).

Costa, Manuel F. M.

1995-10-01

In this communication we make a brief presentation of the branch of Applied Optics of the University of Mihno's undergraduate course of Applied Physics. The course of Applied Physics began in the year 1988/89. Previously we had just a course devoted to the formation of future physics and chemistry teachers at high school level. The Applied Physics course specialized in Optics appeared due to the growth of the physics department and due to request from the industry. The Applied Physics course has two specialization's on the field of applied optics: Optometry; and Optics and Lasers. The topics covered in the two first years of the course ar common to the two branches. On the second semester of the third year the students must choose between either one. The number of students on the Optometry branch was usually almost four times the number of Applied Optics and Lasers students. Nevertheless this tendency is rapidly changing. A short analysis of the result obtained will be presented focusing on last couple of years' advances. Presented will also be the results of an inquest made on students's opinions about the quality of the course, and their own performance and expectations.

approximately 25% of older people who fall and receive paramedic care are not subsequently transported to an emergency department (ED). These people are at high risk of future falls, unplanned healthcare use and poor health outcomes. to evaluate the impact of a fall-risk assessment and tailored fall prevention interventions among older community-dwellers not transported to ED following a fall on subsequent falls and health service use. Randomised controlled trial involving 221 non-transported older fallers from Sydney, Australia. the intervention targeted identified risk factors and used existing services to implement physiotherapy, occupational therapy, geriatric assessment, optometry and medication management interventions as appropriate. The control group received individualised written fall prevention advice. primary outcome measures were rates of falls and injurious falls. Secondary outcome measures were ambulance re-attendance, ED presentation, hospitalisation and quality of life over 12 months. Analysis was by intention-to-treat and per-protocol according to self-reported adherence using negative binominal regression and multivariate analysis. ITT analysis showed no significant difference between groups in subsequent falls, injurious falls and health service use. The per-protocol analyses revealed that the intervention participants who adhered to the recommended interventions had significantly lower rates of falls compared to non-adherers (IRR: 0.53 (95% CI : 0.32-0.87)). a multidisciplinary intervention did not prevent falls in older people who received paramedic care but were not transported to ED. However the intervention was effective in those who adhered to the recommendations. the trial is registered at the Australian New Zealand Clinical Trials Registry: ACTRN 12611000503921, 13/05/2011. © The Author 2016.

Optometric supply and demand in Australia: 2001-2031.

PubMed

Kiely, Patricia M; Healy, Ernest; Horton, Peregrine; Chakman, Joseph

2008-07-01

Major influences on health workforce supply include factors such as graduate numbers, retention rates and immigration. This report presents a model of the relationship of the projected Australian optometric workforce and projected optometric service demand for the period 2001 to 2031. Two contrasting hypothetical optometric supply-side scenarios are presented. Data from the Australian Bureau of Statistics on age and gender of people listing optometry as their major qualification in the 2001 census were projected over a 30-year period, accounting for factors such as ageing, attrition, new graduates and migration. Data were compared to the numbers of optometrists calculated as necessary to meet the demand for services of the Australian population to 2031. The projections indicated that in 2031, there would be 4,072 equivalent full-time optometrists, an excess of 6.9 per cent compared with demand and that of these 38 per cent would be female. Application of a 'high' growth scenario, based on increases in the proportion of optometrists in active practice, working hours by females and graduate and immigrant numbers, resulted in a projected oversupply of up to 30 per cent. Use of a 'low' growth scenario, based on decreases in the proportion of optometrists in active practice, working hours, graduate and immigrant numbers, resulted in a projected undersupply of at least 21.5 per cent. Projected numbers of optometrists using current weightings for mortality, attrition, proportion of optometrists in active practice, working hours, immigration and new graduates indicate that in 2031, there will be adequate numbers of optometrists to meet the demand for services, if service utilisation is maintained at current levels or increased slightly. The adequacy of projected numbers varies considerably if alterations are made to the weighting factors using 'high' and 'low' growth scenarios.

A tribute to Dr. Robert C. Allen, an inspirational teacher, humanitarian, and friend (Nov. 18, 1950-Mar. 24, 2005).

Dr. Robert C. Allen was a gifted educator, as well as experienced ophthalmologist, who was a close personal friend of Dr. Edlich at the University of Virginia Health System. While serving on the faculty at the University of Virginia Health System, Dr. Allen proved to be a compassionate physician, who developed close personal relationships with the residents, faculty, and his patients. Dr. Allen was invited by Dr Edlich to be a member of the Editorial Board of the Journal of Long-Term Effects of Medical Implants. When Dr. Allen told Dr. Edlich that he had ocular melanoma in 2000, this news was a wake-up call to Dr. Edlich on the need to prevent skin cancer, as well as ocular melanoma. Empowered by this news, Dr. Edlich was honored to co-author four articles on skin cancer prevention, as well as the latest article focusing on prevention of ocular melanoma. The Ocular Melanoma Foundation (Richmond, VA (USA)) was founded in 2003 by Dr. Robert C. Allen to increase awareness, enhance education, and provide advocacy among both patients and health care professionals regarding this rare, but potentially lethal cancer. It has a website that provides patient information, up-to-date information and enables communication/ discourse between and among patients and practitioners (admin@ocularmelanoma.org). Dr. Allen died on March 24, 2005, at his home surrounded by family and loved ones. When surgeons are faced with challenging healthcare diseases, Dr. Edlich's mentor, Dr. Owen Wangensteen, advised Dr. Edlich that he should seek the advice and guidance of skilled basic scientists, who are familiar with the problem. Dr. Wangensteen is recognized as the greatest surgical teacher during the 20th century. Consequently, Dr. Edlich enlisted the advice and guidance from the two co-authors of the next article regarding the scientific basis for the selection of sunglasses to prevent the development of cataracts, pterygia, skin cancer, as well as ocular melanoma. Dr. Reichow is a Professor of Optometry at Pacific University College of Optometry (Forest Grove, OR (USA)). Dr. Citek is Associate Professor of Optometry at Pacific University College of Optometry (Forest Grove (USA)). In their comprehensive evaluation of sunglasses, they found some disturbing results. Despite being endorsed by The Skin Cancer Foundation, the Walgreens eyewear samples offer only partial protection to the potential hazards of sunlight exposure. Those individuals who spend considerable time outdoors should seek sun filter eyewear with impact resistant polycarbonate lenses that provide 100% ultraviolet filtration, high levels of blue light filtration, and full visual field lens/frame coverage as provided by high wrap eyewear. There are several brands that offer products with such protective characteristics. Performance sun eyewear by Nike Vision (Nike Inc., Portland OR [USA]), available in both corrective and plano (nonprescription) forms, is one such brand incorporating these protective features, as well as patented optical and tint designs. Numerous Nike styles offer interchangeable lens options to meet the changing environmental conditions encountered outdoors. These technologies are incorporated into performance-driven frame designs inspired by feedback from some of the world's best athletes. Nonprescription Nike eyewear are available on-line at http://www.nike.com/nikevision, as well as at various well-known retail outlets. Nonprescription and prescription Nike eyewear are also available at the offices of many eye care professionals. Even though our latest report did not include soft contact lens, it is important to emphasize that Dr. Reichow and Dr. Citek have played a leadership role in coordinating the development of the Nike MAXSIGHT, an innovative fully tinted soft contact lens. This contact lens provides distortion-free optics, whether or not you wear prescription contacts. They filter out more than 90% of harmful blue light and 95% of UVA and UVB. For the contact lens, you should go to the website for more information http://www.nike.com/nikevision/content.html. The website has a list of practitioners who can service the patients with the respective sunglasses. With their exciting technologic advances in sunglass products, as well as tinted soft contact lens, the authors would encourage Nike Vision to develop an expanded international marketing program that allows all individuals in the world to easily purchase its products.

The OSU aircraft code is used to analyze and simulate the TCAS 2 circular array which is mounted on the fuselage of a Boeing 737 aircraft. It is shown that the sum and difference patterns radiated by the circular array are distorted by the various structures of the aircraft, i.e., wings, tail, etc. Furthermore, monopulse curves are calculated and plotted for several beam positions and THETA angles. As expected, the worst cases of distortion occur when the beams are pointed toward the tail of the aircraft.

On call at the mall: a mixed methods study of U.S. medical malls

PubMed Central

2013-01-01

Background The decline of the traditional U.S. shopping mall and a focus on more consumer- centered care have created an opportunity for “medical malls”. Medical malls are defined as former retail spaces repurposed for healthcare tenants or mixed-use medical/retail facilities. We aimed to describe the current reach of healthcare services in U.S. malls, characterize the medical mall model and emerging trends, and assess the potential of these facilities to serve low-income populations. Methods We used a mixed methods approach which included a comprehensive literature review, key informant interviews, and a descriptive analysis of the Directory of Major Malls, an online retail database. Results Six percent (n = 89) of large, enclosed shopping malls in the U.S. include at least one non-optometry or dental healthcare tenant. We identified a total of 28 medical malls across the U.S., the majority of which opened in the past five years and serve middle or high income populations. Stakeholders felt the key strengths of medical malls were more convenient access including public transportation, greater familiarity for patients, and “one stop shopping” for primary care and specialty services as well as retail needs. Conclusions While medical malls currently account for a small fraction of malls in the US, they are a new model for healthcare with significant potential for growth. PMID:24209495

Oklahoma State University-Center for Health Sciences (OSU-CHS) has replaced its microbiology wet laboratory with a variety of tutorials including a case-based interactive session called Microbial Jeopardy!. The question remains whether the time spent by students and faculty in the interactive case-based tutorial is worthwhile? This study was designed to address this question by analyzing both student performance data and assessing students' perceptions regarding the tutorial. Both quantitative and qualitative data were used in the current study. Part One of the study involved assessing student performance using archival records of seven case-based exam questions used in the 2004, 2005, 2006, and 2007 OSU-CHS Medical Microbiology course. Two sample t-tests for proportions were used to test for significant differences related to tutorial usage. Part Two used both quantitative and qualitative means to assess student's perceptions of the Microbial Jeopardy! session. First, a retrospective survey was administered to students who were enrolled in Medical Microbiology in 2006 or 2007. Second, responses to open-ended items from the 2008 course evaluations were reviewed for comments regarding the Microbial Jeopardy! session. Both student performance and student perception data support continued use of the tutorials. Quantitative and qualitative data converge to suggest that students like and learn from the interactive, case-based session. The case-based tutorial appears to improve student performance on case-based exam questions. Additionally, students perceived the tutorial as helpful in preparing for exam questions and reviewing the course material. The time commitment for use of the case-based tutorial appears to be justified.

Since fulfilling Austin Post’s prediction of impending retreat in the late 1970s, Columbia Glacier has repeatedly surprised both casual and careful observers with its ability for rapid change. Over the last three decades, Columbia Glacier has lost approximately 18 km of its original 66 km length, while thinning by approximately 50% at the present terminus. The total ice volume lost to the Gulf of Alaska Estimates upwards of 120 km3 constrain the total ice volume lost to the Gulf of Alaska. Recently, the terminus supported a ~1.5 km long floating tongue for over than a year, contradicting the common assumption that the mechanical properties of temperate ice prohibit flotation over sustained time intervals. The rich history of study offers an opportunity to better understand tidewater glacier retreat, and a valuable analog to the dynamic instability underway at several ice sheet outlet glaciers. Current research aims to improve processing resolution of existing aerial photographic data, while complimenting the 30-year photogrammetric record with a suite of field observations. Recent instrumentation includes: oblique time lapse and still imagery, semi-permanent GPS, airborne radar, mass balance, passive seismology and LiDAR. This presentation will focus on innovative methods developed in recent field seasons, sharing insight each has provided into the retreat process . 1The Columbia Glacier Consortium consists of: Fabian Walter (SIO), Kenichi Matsuoka (NPI), Ben Smith (UW), Ethan Welty (CU-Boulder), Chris Larsen (UAF), Dave Finnegan (CRREL), Dan McNamara (USGS), Yushin Ahn (OSU), Julie Markus (OSU), Adam LeWinter (EIS).

Cholera is an acute illness characterized by profuse watery diarrhea. It is caused by vibrio cholera subgroup 01 and 0139. Rapid administration of fluid replacement therapy and supportive treatment can reduce mortality to around 1%. By the close of 2011, 10,628 cases and 100 deaths were reported in Ghana with a case fatality rate of 0.99. It is important to evaluate the cholera surveillance system in Ghana to determine if it is meeting its objective. The study was conducted in Osu Klottey district in the Accra Metropolitan area in January 2014. We assessed the operations (attributes and performance) of the surveillance system for cholera using CDC guidelines (2001). Surveillance data records at the district level from 2011-2013 were extracted and analyzed for frequency using Microsoft excel. Stakeholders and key informants were interviewed using structured questionnaire. Records were also reviewed at some health facilities and at district levels. In 2011 and 2012, case fatality rates (1.3% and 0.65%) respectively. Males were mostly affected. The most affected age group was 20-29. In 2011, Predictive value positive was 69.2% and 50% in 2012.Cholera peaked in March 2011 and April 2012. The Government of Ghana funded the system. The system is sensitive, simple, stable, flexible, acceptable and representative. It was also useful and data quality was relatively good. Predictive Value Positive was also good. The surveillance system is achieving its set out objectives. The system is sensitive, simple, stable, flexible, and acceptable. Predictive value positive was good.

2006-07-01

Current Probabilistic Risk Assessment (PRA) methodology is well established in analyzing hardware and some of the key human interactions. However processes for analyzing the software functions of digital systems within a plant PRA framework, and accounting for the digital system contribution to the overall risk are not generally available nor are they well understood and established. A recent study reviewed a number of methodologies that have potential applicability to modeling and analyzing digital systems within a PRA framework. This study identified the Dynamic Flow-graph Methodology (DFM) and the Markov Methodology as the most promising tools. As a result of thismore » study, a task was defined under the framework of a collaborative agreement between the U.S. Nuclear Regulatory Commission (NRC) and the Ohio State Univ. (OSU). The objective of this task is to set up benchmark systems representative of digital systems used in nuclear power plants and to evaluate DFM and the Markov methodology with these benchmark systems. The first benchmark system is a typical Pressurized Water Reactor (PWR) Steam Generator (SG) Feedwater System (FWS) level control system based on an earlier ASCA work with the U.S. NRC 2, upgraded with modern control laws. ASCA, Inc. is currently under contract to OSU to apply DFM to this benchmark system. The goal is to investigate the feasibility of using DFM to analyze and quantify digital system risk, and to integrate the DFM analytical results back into the plant event tree/fault tree PRA model.

Preventing sight loss in older people. A qualitative study exploring barriers to the uptake of regular sight tests of older people living in socially deprived communities in South Wales.

PubMed

Biddyr, S; Jones, A

2015-02-01

This paper describes research findings that try to understand some of the reasons that prevent older people in deprived communities in South Wales from accessing NHS funded sight tests and leads to a discussion of suitable interventions that seek to improve access to primary eye care services and prevent avoidable sight loss. Data were collected from eight focus groups (n = 63) of mixed gender and ages (60-80+ years), of white origin living in deprived communities in South Wales. Individuals were recruited for the focus groups by extensively publicizing the project, with a range of health and older people's community services and groups such as sheltered housing complexes, stroke support groups and coffee morning groups. The study included people who attended optometry services and people not engaged with services. A purposive sampling technique summarizes the sampling approach taken, an approach which the team utilized to recruit 'information rich' cases, namely individuals, groups and organizations that provided the greatest insight into the research question. Focus groups were recorded and transcribed verbatim. Data underwent thematic content analysis and subsequent interpretations were corroborated by expert advisors and a project steering group. Cost was perceived as a significant barrier to accessing sight tests, particularly in relation to purchasing glasses. Other barriers included the perceived pressure to buy glasses associated with visits to the optometrists; poor understanding of the purpose of a sight test in a health prevention context and acceptance of deteriorating sight loss due to the ageing process. Areas of improvement for the delivery of preventative eye health services to older people are identified, as are areas for reflection on the part of those who work within the eye health industry.

A multidisciplinary approach to solving computer related vision problems.

PubMed

Long, Jennifer; Helland, Magne

2012-09-01

This paper proposes a multidisciplinary approach to solving computer related vision issues by including optometry as a part of the problem-solving team. Computer workstation design is increasing in complexity. There are at least ten different professions who contribute to workstation design or who provide advice to improve worker comfort, safety and efficiency. Optometrists have a role identifying and solving computer-related vision issues and in prescribing appropriate optical devices. However, it is possible that advice given by optometrists to improve visual comfort may conflict with other requirements and demands within the workplace. A multidisciplinary approach has been advocated for solving computer related vision issues. There are opportunities for optometrists to collaborate with ergonomists, who coordinate information from physical, cognitive and organisational disciplines to enact holistic solutions to problems. This paper proposes a model of collaboration and examples of successful partnerships at a number of professional levels including individual relationships between optometrists and ergonomists when they have mutual clients/patients, in undergraduate and postgraduate education and in research. There is also scope for dialogue between optometry and ergonomics professional associations. A multidisciplinary approach offers the opportunity to solve vision related computer issues in a cohesive, rather than fragmented way. Further exploration is required to understand the barriers to these professional relationships. © 2012 The College of Optometrists.

[Accuracy of three common optometry methods in examination of refraction in juveniles].

2016-02-01

To compare the results of the three methods of Suresight handheld autorefractor, table-mounted autorefractor and retinoscopy in examination of juveniles patients with or without cycloplegia.
 Firstly, 156 eyes of 78 juveniles (5 to 17 years old) were examined by using WelchAllyn Suresight handheld autorefractor and NIDEK ARK-510A table-mounted autorefractor with or without cycloplegia; secondly, retinoscopy was performed with cycloplegia.
 The spherical power measured by methods without cycloplegia were significantly greater than those measured with cycloplegia (P<0.05); without cycloplegia, there was no significant difference in spherical power, cylindrical power and cylindrical axis between Suresight handheld autorefractor and retinoscopy (P>0.05). These results were highly consistent, suggesting a tendency towards a short sight. However, the spherical power and cylindrical power measured by table-mounted autorefractor was significantly different (P<0.05); with cycloplegia, there was significant difference in spherical power between Suresight handheld autorefractor and retinoscopy (P<0.05).
 Cycloplegic retinoscopy is necessary for juvenile refraction examination. Under natural pupil situation, Suresight handheld autorefractor is better than table-mounted autorefractor, though both show a myopia tendency. Nevertheless, table-mounted autorefractor can be taken as a recommendation for the prescription of lens trial. As a strong reference for subjective optometry, retinoscopy should be the gold standard for measuring refractive errors.

Comparison of examination fees and availability of routine vision care by optometrists and ophthalmologists.

PubMed Central

Soroka, M

1991-01-01

A national telephone survey of eye care practitioners shows that the average fee for routine eye examinations was less among optometrists than ophthalmologists. The average wait for the earliest appointment was 5 days for optometrists and 20 days for ophthalmologists. Weekend and evening appointments were also more obtainable among optometrists. The study did not determine what tests were included in the routine examination of each practitioner. Optometrists are licensed to use diagnostic drugs in all 50 States and prescribe therapeutic drugs for the treatment of ocular diseases in 25 States. Legislation that would update State laws permitting doctors of optometry to prescribe and use pharmaceutical agents for the treatment of eye diseases has been introduced in many of the remaining States. Supporters of bills permitting therapeutic pharmaceutical optometry contend that these changes would ensure the availability of quality eye care at significant savings, since optometric fees are generally lower than ophthalmological fees. In addition, it has been argued that optometrists are equitably distributed geographically and are more likely to have weekend and evening office hours, thus enabling increased patient access to eye care. When considering cost-effectiveness and accessibility, this study may provide information to those States considering changes in the scope of optometric licensure. PMID:1908597

Aitken, Michael J

2012-04-01

Only a very few American opticians (optometrists) wrote textbooks or manuals before the end of the 19th century. The important hand-book by William Bohne has already been excellently covered by David Goss but three others appear to have been largely unnoticed. These are manuals by Walter Alden, August Morck and J W Queen & Co.: pioneer works that can be regarded as the incunabula or cradle of printing of optometric publishing in the United States.

This study aims to identify the health needs of children placed in out-of-home care in regional Queensland and to compare them with the needs of similar children in metropolitan Queensland. Retrospective chart review and subsequent analysis of data from the first assessments of the children placed in care from January 2005 to April 2011. Health needs based on assessment recommendations were then compared with needs and recommendations from a similar clinic in metropolitan Brisbane. Two hundred thirty-nine first assessments were reviewed. The average number of health referrals arising out of each assessment was 2. 72% children were between 2 and 12 years of age and accounted for 76% of the health referrals made. The 10-13% of the children needed referrals for medical and surgical specialties, audiology, speech pathology, dental, and ophthalmology/optometry, each. A percentage of 30 needed ongoing paediatric care. The 15% needed immunisation catch up, 35% counselling and behaviour management, and 15% formal mental health referrals. These were comparable to the health needs identified in out-of-home care children residing in metropolitan Queensland. Children in care who live in a regional setting have similar health-care needs compared with urban children. Given restricted health services in regional settings, there is difficulty in accessing services to meet these needs. © 2014 The Authors.

As a response to recommendations from a report from the Institute of Medicine, NCI is reorganizing it clinical trial groups into a National Clinical Trial Network (NCTN) that consists of four adult groups (Alliance, ECOGACRIN, NRG, and SWOG) and one children’s group (COG). NRG will house CIRO, a center to promote innovative radiation therapy research and intergroup collaboration in radiation. The quality assurance groups that support clinical trials have also been restructured. ITC, OSU Imaging corelab, Philadelphia Imaging core-lab, QARC, RPC, and RTOGQA have joined together to create the Imaging and Radiation Oncology Core (IROC) Group. IROC’s mission is tomore » provide integrated radiation oncology and diagnostic imaging quality control programs in support of the NCI’s NCTN thereby assuring high quality data for clinical trials designed to improve the clinical outcomes for cancer patients worldwide. This will be accomplished through five core services: site qualification, trial design support, credentialing, data management, case review.These changes are important for physicist participating in NCI clinical trials to understand. We will describe in detail the IROC’s activities and five core services so that as a user, the medical physicist can learn how to efficiently utilize this group. We will describe common pitfalls encountered in credentialing for current protocols and present methods to avoid them. These may include the which benchmarks are required for NSABP B-51/RTOG 1304 and how to plan them as well as tips for phantom planning. We will explain how to submit patient and phantom cases in the TRIAD system used by IROC. Learning Objectives: To understand the basic organization of IROC, its mission and five core services To learn how to use TRIAD for patient and phantom data submission To learn how to avoid common pitfalls in credentialing for current trials.« less

Simple sequence repeat (SSR) markers are a major molecular tool for genetic and genomic research that have been extensively developed and used in major crops. However, few are available in African bermudagrass (Cynodon transvaalensis Burtt-Davy), an economically important warm-season turfgrass species. African bermudagrass is mainly used for hybridizations with common bermudagrass [C. dactylon var. dactylon (L.) Pers.] in the development of superior interspecific hybrid turfgrass cultivars. Accordingly, the major objective of this study was to develop and characterize a large set of SSR markers. Genomic DNA of C. transvaalensis '4200TN 24-2' from an Oklahoma State University (OSU) turf nursery was extracted for construction of four SSR genomic libraries enriched with [CA](n), [GA](n), [AAG](n), and [AAT](n) as core repeat motifs. A total of 3,064 clones were sequenced at the OSU core facility. The sequences were categorized into singletons and contiguous sequences to exclude redundancy. From the two sequence categories, 1,795 SSR loci were identified. After excluding duplicate SSRs by comparison with previously developed SSR markers using a nucleotide basic local alignment tool, 1,426 unique primer pairs (PPs) were designed. Out of the 1,426 designed PPs, 981 (68.8 %) amplified alleles of the expected size in the donor DNA. Polymorphisms of the SSR PPs tested in eight C. transvaalensis plants were 93 % polymorphic with 544 markers effective in all genotypes. Inheritance of the SSRs was examined in six F(1) progeny of African parents 'T577' × 'Uganda', indicating 917 markers amplified heritable alleles. The SSR markers developed in the study are the first large set of co-dominant markers in African bermudagrass and should be highly valuable for molecular and traditional breeding research.

Variation in the sizes of eggs and oncospheres and the numbers and distributions of testes in the tapeworm, Hymenolepis diminuta.

Four "strains" of Hymenolepis diminuta were examined for morphological variation. These included the ARME "strain" (currently maintained at the University of Keele, U.K.), the OSU "strain" (currently maintained at The Ohio State University) and the TOR (or UT) "strain" (currently maintained at the University of Toronto), all of which were derived from the parental RICE "strain," and the ANU "strain" (currently maintained at the Australian National University). Additionally, 2 separate "clonal" populations (populations derived from single cysticercoids) from both the OSU and ANU "strains" were examined. All "strains" and "clones" were maintained under identical conditions using Tenebrio molitor and male Sprague-Dawley rats as the intermediate and definitive hosts, respectively. The lengths and widths of eggs and larvae (oncospheres) passed in the hosts' feces, and the numbers and distributions of testes in proglottids were quantified and the data analyzed. Although analyses of the lengths and widths of eggs and larvae demonstrated significant differences among some "strains" and "clones," a discriminate analysis of the data indicated these parameters to be of questionable taxonomic significance. The eggs of all "strains" and "clones" consisted of 2 distinct populations differing in density and size but not infectivity; the relative proportions of eggs in the 2 populations were not determined. Considering all possible numbers and distributions of testes, 17 variations were seen in the strobilae of tapeworms. Analyses of the data demonstrated that the "strains" and "clones" could be differentiated clearly using only the frequencies of the 1p2a (1 poral and 2 aporal testes) or 1p3a distribution, or the frequencies of proglottids containing 3 or 4 testes; all other variations failed to clearly differentiate or group the various "strains" and "clones."(ABSTRACT TRUNCATED AT 250 WORDS)

Discovery of a unique Ig heavy-chain (IgT) in rainbow trout: Implications for a distinctive B cell developmental pathway in teleost fish

Hansen, J.D.; Landis, E.D.; Phillips, R.B.

2005-01-01

During the analysis of Ig superfamily members within the available rainbow trout (Oncorhynchus mykiss) EST gene index, we identified a unique Ig heavy-chain (IgH) isotype. cDNAs encoding this isotype are composed of a typical IgH leader sequence and a VDJ rearranged segment followed by four Ig superfamily C-1 domains represented as either membrane-bound or secretory versions. Because teleost fish were previously thought to encode and express only two IgH isotypes (IgM and IgD) for their humoral immune repertoire, we isolated all three cDNA isotypes from a single homozygous trout (OSU-142) to confirm that all three are indeed independent isotypes. Bioinformatic and phylogenetic analysis indicates that this previously undescribed divergent isotype is restricted to bony fish, thus we have named this isotype "IgT" (??) for teleost fish. Genomic sequence analysis of an OSU-142 bacterial artificial chromosome (BAC) clone positive for all three IgH isotypes revealed that IgT utilizes the standard rainbow trout VH families, but surprisingly, the IgT isotype possesses its own exclusive set of DH and JH elements for the generation of diversity. The IgT D and J segments and ?? constant (C) region genes are located upstream of the D and J elements for IgM, representing a genomic IgH architecture that has not been observed in any other vertebrate class. All three isotypes are primarily expressed in the spleen and pronephros (bone marrow equivalent), and ontogenically, expression of IgT is present 4 d before hatching in developing embryos. ?? 2005 by The National Academy of Sciences of the USA.

2020 Vision: Envisioning a new generation of STEM learning research

Dierking, Lynn D.; Falk, John H.

2016-03-01

In this issue, we have compiled six original papers, outcomes from the U.S. National Science Foundation (US-NSF)-funded REESE (Research and Evaluation on Education in Science and Engineering) 2020 Vision: The Next Generation of STEM Learning Research project. The purpose of 2020 Vision was to re-envision the questions and frameworks guiding STEM research in the twenty-first century, given that notions of learning have changed significantly in the last decade. The papers present diverse research principles that emerged from an initial 2020 Vision conference at Oregon State University (OSU), were then vetted more broadly with the science education community nationally and internationally, and presented in a public 2020 Vision symposium series also at OSU. Individually and as a group, these papers argue that if STEM learning is lifelong, life-wide and life-deep, research designs need to cut across the diverse settings and investigate the multiple contexts and media in which learners live and interact. Authors call for research paradigms that holistically reflect questions of the "what, when, where, why, how and with whom" of STEM learning. Associated Forum papers respond and expand the conversation by critically examining the recommended research principles and in some cases, challenging both authors and editors to think even more broadly. Two Key Contributor pieces highlight the contributions of researchers who have helped to push on these research boundaries, advancing science education research nationally and internationally. A final synthesis paper, a case study of research being conducted in a diverse, under-resourced community in Portland, Oregon provides one example of how the 2020 Vision research principles might be integrated into a comprehensive STEM learning research study.

Carbon and nitrogen nutrient balance signaling in plants.

PubMed

Zheng, Zhi-Liang

2009-07-01

Cellular carbon (C) and nitrogen (N) metabolism must be tightly coordinated to sustain optimal growth and development for plants and other cellular organisms. Furthermore, C/N balance is also critical for the ecosystem response to elevated atmospheric CO(2). Despite numerous physiological and molecular studies in C/N balance or ratio response, very few genes have been shown to play important roles in C/N balance signaling. During recent five years, exciting progress was made through genetic and genomic studies. Several DNA microarray studies have shown that more than half of the transcriptome is regulated by C, N and the C-N combination. Three genetic studies involving distinct bioassays have demonstrated that a putative nitrate transporter (NTR2.1), a putative glutamate receptor (GLR1.1) and a putative methyltransferase (OSU1) have important functions in the C/N balance response. OSU1 is identical to QUA2/TSD2 which has been implicated to act in cell wall biogenesis, indicating a link between cell wall property and the C/N balance signaling. Given that many investigations are only focused on C alone or N alone, the C/N balance bioassays and gene expression patterns are discussed to assist phenotypic characterization of C/N balance signaling. Further, re-examination of those previously reported sugar or nitrogen responsive genes in C/N balance response may be necessary to dissect the C/N signaling pathways. In addition, key components involved in C-N interactions in bacterial, yeast and animal systems and whether they are functionally conserved in plants are discussed. These rapid advances have provided the first important step towards the construction of the complex yet elegant C/N balance signaling networks in plants.

Hazards of soil-borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb-contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb acetate reference diet. Diets containing soil from five Pb-contaminated Superfund sites had relative bioavailabilities from 33%-63%, with a mean of about 50%. Treatment of two of the soils with phosphorus significantly reduced the bioavailability of Pb. Bioaccessibility of Pb in the test soils was then measured in six in vitro tests and regressed on bioavailability. They were: the “Relative Bioavailability Leaching Procedure” (RBALP) at pH 1.5, the same test conducted at pH 2.5, the “Ohio State University In vitro Gastrointestinal” method (OSU IVG), the “Urban Soil Bioaccessible Lead Test”, the modified “Physiologically Based Extraction Test” and the “Waterfowl Physiologically Based Extraction Test.” All regressions had positive slopes. Based on criteria of slope and coefficient of determination, the RBALP pH 2.5 and OSU IVG tests performed very well. Speciation by X-ray absorption spectroscopy demonstrated that, on average, most of the Pb in the sampled soils was sorbed to minerals (30%), bound to organic matter (24%), or present as Pb sulfate (18%). Additional Pb was associated with P (chloropyromorphite, hydroxypyromorphite and tertiary Pb phosphate), and with Pb carbonates, leadhillite (a lead sulfate carbonate hydroxide), and Pb sulfide. The formation of chloropyromorphite reduced the bioavailability of Pb and the amendment of Pb-contaminated soils with P may be a thermodynamically favored means to sequester Pb.

Testing of Selected Geopotential Models in Terms of GOCE Satellite Orbit Determination Using Simulated GPS Observations

2016-04-01

This work contains a comparative study of performance of twenty geopotential models in an orbit estimation process of the satellite of the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission. For testing, among others, such models as JYY_GOCE02S, ITG-GOCE02, ULUX_CHAMP2013S, GOGRA02S, ITG-GRACE2010S, EIGEN-51C, EGM2008, EGM96, JGM3, OSU91a, OSU86F were adopted. A special software package, called the Orbital Computation System (OCS), based on the classical method of least squares was used. In the frame of OCS, initial satellite state vector components are corrected in an iterative process, using the given geopotential model and the models describing the remaining gravitational perturbations. An important part of the OCS package is the 8th order Cowell numerical integration procedure, which enables a satellite orbit computation. Different sets of pseudorange simulations along reference GOCE satellite orbital arcs were obtained using real orbits of the Global Positioning System (GPS) satellites. These sets were the basic observation data used in the adjustment. The centimeter-accuracy Precise Science Orbit (PSO) for the GOCE satellite provided by the European Space Agency (ESA) was adopted as the GOCE reference orbit. Comparing various variants of the orbital solutions, the relative accuracy of geopotential models in an orbital aspect is determined. Full geopotential models were used in the adjustment process. However, the solutions were also determined taking into account truncated geopotential models. In such case, an accuracy of the orbit estimated was slightly enhanced. The obtained solutions refer to the orbital arcs with the lengths of 90-minute and 1-day.

Breakthrough results were achieved during the reporting period in the areas of organic spintronics. (A) For the first time the giant magnetic resistance (GMR) was observed in spin valve with an organic spacer. Thus we demonstrated the ability of organic semiconductors to transport spin in GMR devices using rubrene as a prototype for organic semiconductors. (B) We discovered the electrical bistability and spin valve effect in a ferromagnet /organic semiconductor/ ferromagnet heterojunction. The mechanism of switching between conducting phases and its potential applications were suggested. (C) The ability of V(TCNE)x to inject spin into organic semiconductors such as rubrene wasmore » demonstrated for the first time. The mechanisms of spin injection and transport from and into organic magnets as well through organic semiconductors were elucidated. (D) In collaboration with the group of OSU Prof. Johnston-Halperin we reported the successful extraction of spin polarized current from a thin film of the organic-based room temperature ferrimagnetic semiconductor V[TCNE]x and its subsequent injection into a GaAs/AlGaAs light-emitting diode (LED). Thus all basic steps for fabrication of room temperature, light weight, flexible all organic spintronic devices were successfully performed. (E) A new synthesis/processing route for preparation of V(TCNE)x enabling control of interface and film thicknesses at the nanoscale was developed at OSU. Preliminary results show these films are higher quality and what is extremely important they are substantially more air stable than earlier prepared V(TCNE)x. In sum the breakthrough results we achieved in the past two years form the basis of a promising new technology, Multifunctional Flexible Organic-based Spintronics (MFOBS). MFOBS technology enables us fabrication of full function flexible spintronic devices that operate at room temperature.« less

In most attempts at modernizing the college physics curriculum one of the first branches of physics to be eliminated is geometrical optics. However, in developing countries where the curriculum must give emphasis to applied areas (if physics is to survive at all!), geometrical optics has a role to play, especially in its relationship to the professional course ''Optometry.'' The author presents a few experiments in geometrical optics with an ophthalmic opitics bias, which could be introduced into the college physics laboratory.

To identify fundamental public health competencies and contents in nursing, pharmacy, teaching, medicine, human nutrition and dietetics, optics and optometry, labor relations and human resources, and social work in graduate programs and to formulate proposals for their improvement. The workshop on Public health contents in graduate programs in the XXI Menorca Public Health School was organized as follows: eight groups were set up, coordinated by 37 Spanish university teachers participating in the workshop and selected through key informants and snowball techniques. Two studies on public health professional competencies and the participants' own graduate programs were used to discuss public health professional competencies and contents and establish recommendations to improve public health programs. Each group worked on a particular degree course and the results were shared in plenary. Professional competencies for the three essential public health functions were indentified in all the degrees, except teaching, optics and optometry, and social work. Some of the competencies included in degrees in nursing, teaching, human nutrition and dietetics, and social work were rewritten to highlight the role of each type of professional in public health functions. The groups agreed on the introductory topics (basic concepts and health determinants) and intervention strategies. Common competencies and contents were identified in graduate programs. Updating public health contents in graduate programs would help to define and promote the profile of public health professionals. Copyright © 2011 SESPAS. Published by Elsevier Espana.

At The Ohio State University (OSU) Hospitals, DUE criteria were established when colfosceril palmitate, a synthetic surfactant, was added to the formulary in January 1991. The DUE criteria were designed to assure appropriate drug use, educate physicians, and establish an effective way to monitor drug use and patient outcome (ie, response rate and complications). The criteria include a mechanism for evaluation and modification of the guidelines, as necessary. In addition, a review process will be used to determine the therapy's cost effectiveness and to serve as a guideline for making recommendations on other surfactant formulations as they become available.

The National Geoelectromagnetic Facility - an open access resource for ultra wideband electromagnetic geophysics (Invited)

NASA Astrophysics Data System (ADS)

Schultz, A.; Urquhart, S.; Slater, M.

2010-12-01

At present, the US academic community has access to two national electromagnetic (EM) instrument pools that support long-period magnetotelluric (MT) equipment suitable for crust-mantle scale studies. The requirements of near surface geophysics, hydrology, glaciology, as well as the full range of crust and mantle investigations require development of new capabilities in data acquisition with broader frequency bandwidth than these existing units, increased instrument numbers, and concomitant developments in 3D/4D data interpretation. NSF Major Research Instrumentation support has been obtained to meet these requirements by developing an initial set of next-generation instruments as a National Geoelectromagnetic Facility (NGF), available to all PIs on a cost recovery basis, and operated by Oregon State University (OSU). In contrast to existing instruments with data acquisition systems specialized to operate within specific frequency bands and for specific electromagnetic methods, the NGF model "Zen/5" instruments being co-developed by OSU and Zonge Research and Engineering Organization are based on modular receivers with a flexible number of digital and analog input channels, designed to acquire EM data at dc, and from frequencies ranging from micro-Hz to MHz. These systems can be deployed in a compact, low power configuration for extended deployments (e.g. for crust-mantle scale experiments), or in a high frequency sampling mode for near surface work. The NGF is also acquiring controlled source EM transmitters, so that investigators may carry out magnetotelluric, audio-MT, radiofrequency-MT, as well as time-domain/transient EM and DC resistivity studies. The instruments are designed to simultaneously accommodate multiple electric field dipole sensors, magnetic fluxgates and induction coil sensors. Sample rates as high as 2.5 MHz with resolution between 24 and 32 bits, depending on sample rate, are specified to allow for high fidelity recording of waveforms. The NGF is accepting instrument use requests from investigators planning electromagnetic surveys via webform submission on its web site ngf.coas.oregonstate.edu. The site is also a port of entry to request access to the 46 long period magnetotelluric instruments also operated by OSU as national instrument pools. Cyberinfrastructure support is available to investigators, including field computers, EM data processing software, and access to a hybrid CPU-GPU parallel computing environment, currently configured with dual Intel Westmere hexacore CPUs and 960 NVidia Tesla and 1792 Nvidia Fermi GPU cores. The capabilities of the Zen/5 receivers will be presented, with examples of data acquired from a recent shallow water marine controlled source experiment conducted in coastal Oregon as part of an effort to locate a buried submarine pipeline, using a 1.1 KW 256 Hz signal source imposed on the pipeline from shore. A Zen/5 prototype instrument, modified for marine use through support by the Oregon Wave Energy Trust, demonstrated the marine capabilities of the NGF instrument design.

Geodesics on SO(3) are characterized by constant angular velocity motions and as great circles on a three-sphere. The former interpretation is widely used in optometry and the latter features in the interpolation of rotations in computer graphics. The simplicity of these two disparate interpretations belies the complexity of the corresponding rotations. Using a quaternion representation for a rotation, we present a simple proof of the equivalence of the aforementioned characterizations and a straightforward method to establish features of the corresponding rotations.

NASA Astrophysics Data System (ADS)

Ham, Tae Kyu

The Very High Temperature Reactor (VHTR) is one of six proposed Generation-IV concepts for the next generation of nuclear powered plants. The VHTR is advantageous because it is able to operate at very high temperatures, thus producing highly efficient electrical generation and hydrogen production. A critical safety event of the VHTR is a loss-of-coolant accident. This accident is initiated, in its worst-case scenario, by a double-ended guillotine break of the cross vessel that connects the reactor vessel and the power conversion unit. Following the depressurization process, the air (i.e., the air and helium mixture) in the reactor cavity could enter the reactor core causing an air-ingress event. In the event of air-ingress into the reactor core, the high-temperature in-core graphite structures will chemically react with the air and could lose their structural integrity. We designed a 1/8th scaled-down test facility to develop an experimental database for studying the mechanisms involved in the air-ingress phenomenon. The current research focuses on the analysis of the air-ingress phenomenon using the computational fluid dynamics (CFD) tool ANSYS FLUENT for better understanding of the air-ingress phenomenon. The anticipated key steps in the air-ingress scenario for guillotine break of VHTR cross vessel are: 1) depressurization; 2) density-driven stratified flow; 3) local hot plenum natural circulation; 4) diffusion into the reactor core; and 5) global natural circulation. However, the OSU air-ingress test facility covers the time from depressurization to local hot plenum natural circulation. Prior to beginning the CFD simulations for the OSU air-ingress test facility, benchmark studies for the mechanisms which are related to the air-ingress accident, were performed to decide the appropriate physical models for the accident analysis. In addition, preliminary experiments were performed with a simplified 1/30th scaled down acrylic set-up to understand the air-ingress mechanism and to utilize the CFD simulation in the analysis of the phenomenon. Previous air-ingress studies simulated the depressurization process using simple assumptions or 1-D system code results. However, recent studies found flow oscillations near the end of the depressurization which could influence the next stage of the air-ingress accident. Therefore, CFD simulations were performed to examine the air-ingress mechanisms from the depressurization through the establishment of local natural circulation initiate. In addition to the double-guillotine break scenario, there are other scenarios that can lead to an air-ingress event such as a partial break were in the cross vessel with various break locations, orientations, and shapes. These additional situations were also investigated. The simulation results for the OSU test facility showed that the discharged helium coolant from a reactor vessel during the depressurization process will be mixed with the air in the containment. This process makes the density of the gas mixture in the containment lower and the density-driven air-ingress flow slower because the density-driven flow is established by the density difference of the gas species between the reactor vessel and the containment. In addition, for the simulations with various initial and boundary conditions, the simulation results showed that the total accumulated air in the containment collapsed within 10% standard deviation by: 1. multiplying the density ratio and viscosity ratio of the gas species between the containment and the reactor vessel and 2. multiplying the ratio of the air mole fraction and gas temperature to the reference value. By replacing the gas mixture in the reactor cavity with a gas heavier than the air, the air-ingress speed slowed down. Based on the understanding of the air-ingress phenomena for the GT-MHR air-ingress scenario, several mitigation measures of air-ingress accident are proposed. The CFD results are utilized to plan experimental strategy and apparatus installation to obtain the best results when conducting an experiment. The validation of the generated CFD solutions will be performed with the OSU air-ingress experimental results. (Abstract shortened by UMI.).

Vision plays a critical role in athletic performance; however, previous studies have demonstrated that a variety of simulated athletic sensorimotor tasks can be surprisingly resilient to retinal defocus (blurred vision). The purpose of the present study was to extend this work to determine the effect of retinal defocus on overall basketball free throw performance, as well as for the factors gender, refractive error and experience. Forty-four young adult participants of both genders were recruited. They had a range of refractive errors and basketball experience. Each performed 20 standard basketball free throws under five lens defocus conditions in a randomised manner: plano, +1.50 D, +3.00 D, +4.50 D and +10.00 D. Overall, free throw performance was significantly reduced under the +10.00 D lens defocus condition only. Previous experience, but neither refractive error nor gender, yielded a statistically significant difference in performance. Consistent with previous studies of complex sensorimotor tasks, basketball free throw performance was resilient to low and moderate levels of retinal defocus. Thus, for a relatively non-dynamic motor task at a fixed far distance, such as the basketball free throw, precise visual clarity was not critical. Other factors such as motor memory may be important. However, in the dynamic athletic competitive environment it is likely that visual clarity plays a more critical role in one's performance level, at least for specific task demands. © 2015 The Authors.

The purpose of this analysis was to compare observer-rated tasks in patients implanted with the Argus II Retinal Prosthesis System, when the device is ON versus OFF. The Functional Low-Vision Observer Rated Assessment (FLORA) instrument was administered to 26 blind patients implanted with the Argus II Retinal Prosthesis System at a mean follow-up of 36 months. FLORA is a multi-component instrument that consists in part of observer-rated assessment of 35 tasks completed with the device ON versus OFF. The ease with which a patient completes a task is scored using a four-point scale, ranging from easy (score of 1) to impossible (score of 4). The tasks are evaluated individually and organised into four discrete domains, including 'Visual orientation', 'Visual mobility', 'Daily life and 'Interaction with others'. Twenty-six patients completed each of the 35 tasks. Overall, 24 out of 35 tasks (69 per cent) were statistically significantly easier to achieve with the device ON versus OFF. In each of the four domains, patients' performances were significantly better (p < 0.05) with the device ON versus OFF, ranging from 19 to 38 per cent improvement. Patients with an Argus II Retinal Prosthesis implanted for 18 to 44 months (mean 36 months), demonstrated significantly improved completion of vision-related tasks with the device ON versus OFF. © 2016 The Authors Clinical and Experimental Optometry published by John Wiley & Sons Australia, Ltd on behalf of Optometry Australia.

In this cross-sectional study, we aimed to determine the prevalence and characteristics of chronic ocular itch in an outpatient ophthalmology and optometry clinic. Four hundred patients from an outpatient ophthalmology and optometry clinic were enrolled. The presence and characteristics of chronic ocular itch were assessed by a questionnaire. Data regarding ophthalmologic, dermatologic, and systemic conditions as well as current medications were extracted from medical records. Chronic ocular itch was present in 118 (29.5%) of 400 participants. Chronic ocular pruritus was significantly more prevalent in females [ P =0.015; odds ratio (OR)=1.8; 95% confidence interval (CI), 1.1-2.8] and was significantly associated with the presence of allergic conjunctivitis [51.8% (n=45); P <0.001; OR=5.0; 95% CI, 3.0-8.3], dry eye syndrome [40.1% (75); P <0.001; OR=2.6; 95% CI, 1.7-4.1], blepharitis [43.8% (n=21); P =0.021; OR=2.0; 95% CI, 1.1-3.8], and atopic dermatitis [50.0% (n=10); P =0.023; OR=2.6; 95% CI, 1.1-5.8]. Chronic ocular itch was not significantly associated with systemic conditions, or the use of prescribed ophthalmologic medications. Chronic ocular itch is common and may be related to ophthalmologic or dermatologic pathologies. The present findings highlight the importance of identifying and managing this uncomfortable symptom that may negatively impact the quality of life and sleep of affected patients.

The training in the use of the slit lamp has always been difficult for students of the degree in Optics and Optometry. Instruments with associated cameras helps a lot in this task, they allow teachers to observe and control if the students evaluate the eye health appropriately, correct use errors and show them how to do it with a visual demonstration. However, these devices are more expensive than those that do not have an integrated camera connected to a display unit. With the aim to improve students' skills in the management of slit lamp, we have adapted USB HD webcams (Microsoft Lifecam HD-5000) to the objectives of the slit lamps available in our contact lenses laboratory room. The webcams are connected to a PC running Linux Ubuntu 11.0; therefore that is a low-cost device. Our experience shows that single method has several advantages. It allows us to take pictures with a good quality of different conditions of the eye health; we can record videos of eye evaluation and make demonstrations of the instrument. Besides it increases the interactions between students because they could see what their colleagues are doing and take conscious of the mistakes, helping and correcting each others. It is a useful tool in the practical exam too. We think that the method supports the training in optometry practice and increase the students' confidence without a huge outlay.

Internet based post-graduate course in spectacle lens design

The complexity of spectacle lenses has increased enormously over the last three decades. The advent of aspheric lenses for the normal power range and the, now commonplace, progressive lenses for the correction of presbyopia, are just two examples of 21st Century technology. Freeform surfaces are now employed to personalize lenses to wearer's needs and these may be both progressive and atoroidal in nature. At the same time, optometry has taken a sideways step from optics and physics into a more general primary health care profession with an ever-increasing amount of biological and medical content added to an already brimming curriculum, hence the need for persons without optometry training to undertake the study of spectacle lenses. Some years ago a post-graduate course was designed for opticians who had a good grasp of mathematics and the ability to pay close attention to detail in the lengthy trigonometric ray-tracing techniques employed in lens design calculations. The year-long course, is undertaken by distance learning, and has been undertaken via the internet by students from many countries around the world. Final assessment is by means of examination held by the Association of British Dispensing Opticians and takes the form of two three-hour papers, Paper One consisting of the determination of the aberrations of a spectacle lens by accurate trigonometric ray tracing and the second, a general paper on the optics of ophthalmic lenses. It leads to the professional qualification, ABDO (Hons) SLD.

Domain-Specific Languages (DSLs) offer an attractive path to Exascale software since they provide expressive power through appropriate abstractions and enable domain-specific optimizations. But the advantages of a DSL compete with the difficulties of implementing a DSL, even for a narrowly defined domain. The DTEC project addresses how a variety of DSLs can be easily implemented to leverage existing compiler analysis and transformation capabilities within the ROSE open source compiler as part of a research program focusing on Exascale challenges. The OSU contributions to the DTEC project are in the area of code generation from high-level DSL descriptions, as well asmore » verification of the automatically-generated code.« less
