Terms modified by Disease Specific Selected AbstractsReview of dyspnoea quantification in the emergency department: Is a rating scale for breathlessness suitable for use as an admission prediction tool?EMERGENCY MEDICINE AUSTRALASIA, Issue 5 2007Amanda Saracino Abstract Acute shortness of breath is a potential marker of serious cardiopulmonary disease and requires rapid assessment. In our current health-care system, increasing pressure on the ED to limit costs and waiting times has resulted in the development of many clinical decision aids and admission prediction tools designed to assist ED physicians in meeting these demands. However, most of these tools are disease specific, and none are currently available for application to patients presenting to the ED with shortness of breath. Although somewhat limited, current evidence supports the utilization of a simple dyspnoea rating scale, to assist in the streamlining of clinical severity assessments and urgency evaluations, and to potentially provide useful information to facilitate rapid and accurate site-of-care decisions in this setting. [source] The experience of living with a chronic illness during adolescence: a critical review of the literatureJOURNAL OF CLINICAL NURSING, Issue 23 2008Rachel M Taylor Aims., To identify and critique literature on the adolescent lived experience of chronic illness; describe the lived experience; and to make recommendations for clinical practice. Background., Young people with chronic illness have the same developmental issues as those who are healthy. However, development can be disrupted by treatment and repeated hospitalisation. While the physical consequences of chronic illness on development have been established, the subjective personal experience is less known. Design., Literature review. Methods., Electronic databases and hand searches were made of the literature published between January 1990,September 2007. Literature was eligible for inclusion if it involved adolescents between 10,19 years, and published in English and used qualitative methods of data collection. Methodological quality was assessed using the criteria described by Cesario et al. [Journal of Obstetrics, Gynaecology and Neonatal Nursing 31 (2002) 31]. Conclusions., Twenty studies were identified involving young people with a wide variety of chronic illnesses. The study quality was variable, however, generally the majority was assessed as being good or fair. Seven common themes were found between the identified studies: developing and maintaining friendships; being normal/getting on with life; the importance of family; attitude to treatment; experiences of school; relationship with the healthcare professionals; and the future. Relevance to practice., As there was commonality in themes between studies strategies to lessen the burden of chronic illness during adolescence do not necessarily need to be disease specific. Nurses need to focus on treating the young person rather than their illness. [source] Pathogenic cysteine mutations affect progranulin function and production of mature granulinsJOURNAL OF NEUROCHEMISTRY, Issue 5 2010Jun Wang J. Neurochem. (2010) 112, 1305,1315. Abstract Frontotemporal dementia with ubiquitin-positive inclusions (FTLD-U) can be caused by mutations in the progranulin gene (GRN). Progranulin (PGRN) is a cysteine-rich growth factor, which is proteolytically cleaved by elastase to produce several granulins (GRNs). All FTLD-U mutations in GRN characterized to date result in reduced secreted PGRN protein. We recently reported a Spanish family with progressive non-fluent aphasia and dementia in which a novel C521Y mutation segregates with disease. A second cysteine mutation (C139R) has also been reported to be disease specific. Allele-specific mRNA expression assays in brain reveal that the C521Y mutant allele is expressed at similar levels to the wild-type allele. Furthermore, plasma PGRN levels in C521Y carriers are comparable with non-carrier family relatives, suggesting that the mutation does not affect PGRN protein expression and secretion in vivo. Despite normal PGRN levels C521Y and C139R mutant GRNs show reduced neurite growth-stimulating activity in vitro. Further study revealed that these mutations also cause impaired cleavage of PGRN by elastase. Our data suggest that these mutations affect the function of full-length PGRN as well as elastase cleavage of PGRN into GRNs, leading to neurodegeneration. [source] Quality of life in acute and maintenance treatment of non-erosive and mild erosive gastro-oesophageal reflux diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2005F. PACE Summary Background:, Quality of life has been assessed in a large, multicentre randomized, open label study. Aim:, To evaluate the economic and clinical consequences of two different maintenance treatment modalities, administered to 6017 gastro-oesophageal reflux disease patients at 451 gastroenterological centres in Italy. Methods:, Adult gastro-oesophageal reflux disease patients received, at enrolment, an acute treatment of esomeprazole 40 mg/day for 4 weeks and, if successfully treated, were randomized into two maintenance treatment strategies: esomeprazole 20 mg/day or esomeprazole on demand for 6 months. A baseline endoscopy allowed the exclusion of grade II,IV oesophagitis according to Savary,Miller's classification. Burden of gastro-oesophageal reflux disease was measured at baseline by the generic questionnaire Short-Form 36 and by a disease specific instrument, quality of life in reflux and dyspepsia (QOLRAD), also administered at start and conclusion of maintenance period. Investigators were required to collect patient judgement about the degree of satisfaction with treatment effect on heartburn, with a 7-point scale. Results:, A comparison between Short-Form 36 scores and the normative source of the Italian general population suggested that symptomatic gastro-oesophageal reflux disease patients experience a worse quality of life than the general population. At the end of the 4-week treatment with esomeprazole 40 mg all (QOLRAD) dimensions showed a statistically significant (P < 0.0001) and clinically meaningful improvement. Satisfaction level towards treatment was reported high in the total enrolled population after acute treatment with esomeprazole 40 mg/day (96.2% satisfied and 64.4% very satisfied). A statistically significant difference in (QOLRAD) scores was registered at the end of maintenance phase in favour of the continuous regimen, nevertheless the size of this difference was very small in all dimensions; similarly, the proportion of patients very satisfied was slightly higher in the continuous treatment arm (64.5%) than in the on-demand arm (59.7%). Conclusions:, Gastro-oesophageal reflux disease can significantly impair health-related quality of life and esomeprazole therapy allows immediate relief in the acute phase of the disease. Quality of life improvement was maintained during the 6-month follow-up with a slight difference in term of quality of life in reflux and dyspepsia scores and patients' satisfaction in favour of the continuous treatment strategy. [source] Developmental pathways in food allergy: a new theoretical frameworkALLERGY, Issue 4 2009A. DunnGalvin Background:, To date, there is no model of psychosocial development based on empirical food allergy (FA) research. This limits the ability of clinicians, researchers and policy-makers to predict and evaluate the real impact of FA on the child, with implications for prevention, treatment, intervention and health policy. Objectives:, To provide an integrated conceptual framework to explain the onset, development and maintenance of FA-related cognitions, emotions and behaviour, with particular attention to transition points. Method:, Fifteen focus groups meetings were held with 62 children (6,15 years). Developmentally appropriate techniques were designed to stimulate discussion, maintain interest and minimize threat to children's self-esteem. Data were analysed using grounded theory. Results:, FA impacts directly on children's normal trajectory of psychological development in both an age- and disease-specific manner. Six key themes emerged from the analysis: ,meanings of food'; ,autonomy, control and self-efficacy'; ,peer relationships'; ,risk and safety'; ,self/identity'; and ,coping strategies'. Conclusions:, Coping with FA is more than simply a strategy, it is a cumulative history of interactive processes (age, gender and disease specific) that are embedded in a child's developmental organization. Clinical Implications:, The early recognition and incorporation of an FA-specific developmental framework into a treatment plan is essential and sets the stage for an effective medical care and the eventual transition from paediatric to adult care. Capsule Summary:, This study represents a first attempt to provide an integrated developmental framework to explain the onset, development and maintenance of FA-related cognitions, emotions and behaviour. [source] The Effects of Smoking on Short-Term Quality of Life Outcomes in Sinus Surgery,THE LARYNGOSCOPE, Issue 12 2007Subinoy Das MD Abstract Objective: The purpose of this study was to prospectively compare the short-term benefit of endoscopic sinus surgery for smokers and nonsmokers using a disease specific, clinically validated, quality of life outcomes measure, the Sinonasal Outcomes Test-20 (SNOT-20). Study Design: Prospective clinical trial. Methods: A total of 235 patients were prospectively enrolled at a single tertiary academic center. Preoperative SNOT-20 scores and comprehensive demographic data were obtained. All patients underwent endoscopic sinus surgery under the supervision of the senior author. Preoperative SNOT-20 scores were compared to short-term postoperative SNOT-20 scores. Results: Short-term postoperative results were available for 221 patients for comparison. Preoperative SNOT-20 scores in 49 smokers (mean: 27.8) and 172 nonsmokers (mean: 26.2) were statistically similar. Both smokers and nonsmokers achieved a highly significant reduction in SNOT-20 scores at short-term follow-up evaluations. (P < .0005) Smokers achieved a greater reduction in SNOT-20 scores (mean difference: 22.1) at short-term follow-up compared to nonsmokers (mean difference: 16.1). This result was statistically significant (P < .044). Conclusions: This study confirms that smokers and nonsmokers achieve a highly significant short-term benefit from endoscopic sinus surgery using a clinically-validated symptom severity scale in a prospective study. Interestingly, smokers achieved a greater short-term benefit than nonsmokers did. This study calls into question the notion that current smokers are poorer candidates for endoscopic sinus surgery. Further prospective studies to confirm these results and provide long-term analysis should be performed. [source] Regulation of transgene expressionACTA OPHTHALMOLOGICA, Issue 2009P KOCH Purpose Regulation of the transgene expression in the targeted cells is of course of major importance when using gene therapy. Actually, we have a huge range of possibilities to regulate gene expression. Methods There are two main classes of promoters: constitutive and inducible promoters. Amongst constitutive promoters, we have two sub-forms: non-tissue and tissue specific promoters. The lasts allows us to better target the tissue or cells in which we want to express our gene of interest. On the other hand, inducible promoters have been widely developed recently and allow us to obtain a regulated expression, depending on different factors. Very recently, disease specific inducible promoters emerged for a more precise regulation. Results We will together examine more precisely the different possibilities offered by gene regulation in Gene Therapy. Thereafter, we will more specifically describe usable promoters in ocular inflammation. Finally we will examine the effects of some inflammatory, disease specific, promoters. Conclusion Regulation of transgene expression is one of the fundaments of efficient gene transfer. Recent developments actually allow us to play within the targeted cell(s) to obtain an expression in specific conditions. [source] | ||||||||||
