A review of scientific literature on inherited disorders in domestic horse breeds

The full extent to which inherited disorders occur in different breeds of domestic horse (Equus caballus) has not been previously been investigated. A systematic search was carried out to review scientific literature on inherited disorders in domestic horse breeds and examine patterns in potentially inherited disorders. A two-part search was conducted: (i) electronic bibliographic databases for published studies; and (ii) existing online databases of inherited disorders in animals. A total of 230 papers were identified, discussing 102 inherited disorders in the horse. Few cases (17) were found in which disorders were reported to have a direct link to a conformational or phenotypic trait. Forty-nine breeds of domestic horse were described as being predisposed to one or more inherited disorders, but such predispositions did not distinguish between genetic or environmental causes. There were few patterns in the number of disorders to which breeds were reportedly predisposed or in the extent to which disorders were researched. The structure and grouping of disorders presented here could assist with standardisation in the terminology used for describing inherited disorders. © 2012 Universities Federation for Animal Welfare The Old School.

A systematic literature review of surgical interventions for limbal stem cell deficiency in humans

PURPOSE: To evaluate the relative benefits and to identify any adverse effects of surgical interventions for limbal stem cell deficiency (LSCD).

DESIGN: Systematic literature review.

METHODS: We searched the following electronic databases from January 1, 1989 through September 30, 2006: MEDLINE, EMBASE, Science citation index, BIOSIS, and the Cochrane Library. In addition, reference lists were scanned to identify any additional reports. The quality of published reports was assessed using standard methods. The main outcome measure was improvement in vision of at least two Snellen lines of best-corrected visual acuity (BCVA). Data on adverse outcomes also were collected.

RESULTS: Twenty-six studies met the inclusion criteria. There were no randomized controlled studies. All 26 studies were either prospective or retrospective case series. For bilateral severe LSCD, keratolimbal allograft was the most common intervention with systemic immunosuppression. Other interventions included eccentric penetrating keratolimbal allografts and cultivated autologous oral mucosal epithelial grafts. An improvement in BCVA of two lines or more was reported in 31% to 67% of eyes. For unilateral severe LSCD, the most common surgical intervention was contralateral conjunctival limbal autograft, with 35% to 88% of eyes gaining an improvement in BCVA of two lines or more. The only study evaluating partial LSCD showed an improvement in BCVA of two lines or more in 39% of eyes.

CONCLUSIONS: Studies to date have not provided strong evidence to guide clinical practice on which surgery is most beneficial to treat various types of LSCD. Standardized data collection in a multicenter LSCD register is suggested.

Sample size in studies on diagnostic accuracy in ophthalmology:A literature survey

Aim: To assess the sample sizes used in studies on diagnostic accuracy in ophthalmology. Design and sources: A survey literature published in 2005. Methods: The frequency of reporting calculations of sample sizes and the samples' sizes were extracted from the published literature. A manual search of five leading clinical journals in ophthalmology with the highest impact (Investigative Ophthalmology and Visual Science, Ophthalmology, Archives of Ophthalmology, American Journal of Ophthalmology and British Journal of Ophthalmology) was conducted by two independent investigators. Results: A total of 1698 articles were identified, of which 40 studies were on diagnostic accuracy. One study reported that sample size was calculated before initiating the study. Another study reported consideration of sample size without calculation. The mean (SD) sample size of all diagnostic studies was 172.6 (218.9). The median prevalence of the target condition was 50.5%. Conclusion: Only a few studies consider sample size in their methods. Inadequate sample sizes in diagnostic accuracy studies may result in misleading estimates of test accuracy. An improvement over the current standards on the design and reporting of diagnostic studies is warranted.

How young people cope with chronic kidney disease:Literature review

Background: Chronic kidney disease (CKD) is a complex, long-term condition occurring in all age groups. It has been reported that the incidence of renal replacement therapy in young people is 7-8 per million population. Notwithstanding those individuals who may receive a donor kidney, many individuals may be disenfranchised by perceptions of helplessness and feelings of powerlessness against a backdrop of diminished health outlook, consequently impacting on capacity for effective coping. Aim: The aim of this review is to explore how young people cope with CKD. Methods: Three hundred and thirty-seven abstracts were identified. Sixty-three papers were cross-examined using a Critical Appraisal Skills Checklist Tool. Results: Young people face various demands; these may be episodic or ongoing, depending on health and circumstance. The themes this review uncovers are: 'Lack of a Coping Definition'; 'Coping Strategies in Young People'; and 'Barriers to the Understanding of Coping in Young People'. Conclusion: More qualitative research is vital to retrieve 'real-life' perceptions from young people coping with kidney disease to identify how care should be made more explicit for them. © 2012 European Dialysis and Transplant Nurses Association/European Renal Care Association.

A literature review of end-stage renal disease and cachexia:Understanding experience to inform evidence-based healthcare

Introduction: Cachexia is a major cause of morbidity and mortality in people who have end-stage renal disease (ESRD). The majority of research into cachexia in ESRD has focused on the biological aspects of the syndrome and potential treatment modalities. While this research is necessary, it predominately focuses on the physical impact of cachexia in ESRD. The multi-dimensional psychosocial ramifications of this syndrome have been highlighted in other end-stage illness trajectories, but have not been systematically explored in persons who have ESRD. Aim: This paper discusses why this research is necessary, alongside further studies to help define the pathophysiology of this syndrome. Conclusion: The rich insightful data gained from understanding the patients' illness experience will positively contribute to the limited knowledge base available and inform future holistic patient-centred care delivery which recognises and responds to not only the biological but also the psychosocial impact of cachexia. © 2013 European Dialysis and Transplant Nurses Association/European Renal Care Association.

'Dark Interpretations': Romanticism's Ambiguous Legacy in India

This essay argues that Romanticism’s legacy in modern Indian literature has been constructed under the shadow of its colonial heritage. Although the Romantic period witnessed the enthusiastic “discovery” of classical Indian literature by British Orientalists, Romantic imperialism (which went hand-in-hand with Romantic orientalism) played a darker role in instituting a colonial educational system in India which denigrated Indian languages and literatures. Modern Indian literature represented by popular fictional writers from R.K. Narayan to Arundhati Roy registers this complex colonial inheritance by its qualified and often ironic celebration of British Romantic literature along with its associated ideologies of freedom, truth, and beauty.

"From Indomania to Indophobia":Thomas De Quincey's Providential Orientalism

Thomas De Quincey’s terrifying oriental nightmares, reported to sensational acclaim in his Confessions of an English Opium-Eater (1821), have become a touchstone of romantic imperialism in recent studies of the literature of the period (Leask 1991; Barrell 1992 et al). De Quincey’s collocation of “all creatures, birds, beasts, reptiles, all trees and plants, usages and appearances, that are found in all tropical regions” in the hypnagogic hallucinations that characterized what he called “the pains of opium” seems to anticipate neatly Said’s theory of orientalism, whereby the orient was supplied by the west with “a mentality, a genealogy, an atmosphere,” the attitudinal basis as he argues for the continuing march of imperialism from the late eighteenth century. Yet, as Thomas Trautmann (1997) has pointed out, orientalist scholarship based in India and led by the influential Asiatic Society of Bengal in the late eighteenth century was extremely enthusiastic about Indian classical antiquity. The early orientalist scholarship posited ethnic, linguistic, cultural and religious links between Europe and India, while recognizing the greater antiquity of Indian civilization. This favourable attitude (which Trautmann calls “Indomania”) was overtaken in the nineteenth century by disavowal of that scholarship and repugnance (which he calls “Indophobia”), influenced by utilitarian and evangelical attitudes to colonialism. De Quincey’s lifespan covers this crucial period of change. My paper examines his evangelical upbringing and interest in biblical and orientalist scholarship to suggest his anxious investment in these modes of thinking. I will suggest that the bizarre orientalist fusions of his dreams can be better understood in the context of changing attitudes to the imperialism during the period. An examination of his work provides a far more dynamic understanding of the processes of orientalism than the binary model suggested by Said. The transformation implied from imperial scholarship to governance, I will suggest, is not irrelevant to a world which continues to pull apart on various grounds of race and ethnicity, and reflects on our own role in the academy today.
