Additional Standard Tax Deduction for the Blind: A Description and Assessment
This report covers the history, reasoning, and current policy that surrounds tax deductions for the blind. Moreover, the report highlights the current policy (as of May 7th 2008) as one that recognizes the higher cost of living for a blind person because many blind taxpayers have low incomes. However, the report points out that because of this many of them have access to an additional deduction for being in a lower income bracket

This report discusses the nature of extenders, as temporary provisions and as tax benefits. Descriptions of the extenders are included
Oral administration of morphine versus ibuprofen to manage postfracture pain in children: A randomized trial
Background: Recent warnings from Health Canada regarding codeine for children have led to increased use of nonsteroidal anti-inflammatory drugs and morphine for common injuries such as fractures. Our objective was to determine whether morphine administered orally has superior efficacy to ibuprofen in fracture-related pain
Modifying effect of dual antiplatelet therapy on incidence of stent thrombosis according to implanted drug-eluting stent type
Aim To investigate the putative modifying effect of dual antiplatelet therapy (DAPT) use on the incidence of stent thrombosis at 3 years in patients randomized to Endeavor zotarolimus-eluting stent (E-ZES) or Cypher sirolimus-eluting stent (C-SES). Methods and results Of 8709 patients in PROTECT, 4357 were randomized to E-ZES and 4352 to C-SES. Aspirin was to be given indefinitely, and clopidogrel/ticlopidine for â„3 months or up to 12 months after implantation. Main outcome measures were definite or probable stent thrombosis at 3 years. Multivariable Cox regression analysis was applied, with stent type, DAPT, and their interaction as the main outcome determinants. Dual antiplatelet therapy adherence remained the same in the E-ZES and C-SES groups (79.6% at 1 year, 32.8% at 2 years, and 21.6% at 3 years). We observed a statistically significant (P = 0.0052) heterogeneity in treatment effect of stent type in relation to DAPT. In the absence of DAPT, stent thrombosis was lower with E-ZES vs. C-SES (adjusted hazard ratio 0.38, 95% confidence interval 0.19, 0.75; P = 0.0056). In the presence of DAPT, no difference was found (1.18; 0.79, 1.77; P = 0.43). Conclusion A strong interaction was observed between drug-eluting stent type and DAPT use, most likely prompted by the vascular healing response induced by the implanted DES system. These results suggest that the incidence of stent thrombosis in DES trials should not be evaluated independently of DAPT use, and the optimal duration of DAPT will likely depend upon stent type (Clinicaltrials.gov number NCT00476957

Additional Standard Tax Deduction for the Elderly: A Description and Assessment
This report briefly summarizes the history, reasoning, and current tax deductions (as of May 7th 2008) for the elderly. The report suggests that the current tax deduction for both the elderly and the blind will result in the loss of 9 billion in tax revenue. Moreover, the report suggests that corrections could be made with alternative solutions

Transcriptomes of aging brain, heart, muscle, and spleen from female and male African turquoise killifish
Abstract The African turquoise killifish is an emerging vertebrate model organism with great potential for aging research due to its naturally short lifespan. Thus far, turquoise killifish aging âomicâ studies have examined a single organ, single sex and/or evaluated samples from non-reference strains. Here, we describe a resource dataset of ribosomal RNA-depleted RNA-seq libraries generated from the brain, heart, muscle, and spleen from both sexes, as well as young and old animals, in the reference GRZ turquoise killifish strain. We provide basic quality control steps and demonstrate the utility of our dataset by performing differential gene expression and gene ontology analyses by age and sex. Importantly, we show that age has a greater impact than sex on transcriptional landscapes across probed tissues. Finally, we confirm transcription of transposable elements (TEs), which are highly abundant and increase in expression with age in brain tissue. This dataset will be a useful resource for exploring gene and TE expression as a function of both age and sex in a powerful naturally short-lived vertebrate model
Functional Status After Transcatheter and Surgical Aortic Valve Replacement: 2-Year Analysis From the SURTAVI Trial.
OBJECTIVES
This study sought to evaluate patient-centered metrics in intermediate-surgical-risk aortic stenosis patients enrolled in the SURTAVI (Surgical Replacement and Transcatheter Aortic Valve Implantation) trial treated with self-expanding transcatheter aortic valve replacement (TAVR) or surgery.
BACKGROUND
Studies have shown TAVR to be an alternative to surgery in patients with severe symptomatic aortic stenosis but have focused on "hard endpoints," including all-cause mortality and stroke, rather than on comparative patient-centered metrics, such as functional status and symptom burden.
METHODS
The study analyzed functional status (6-minute walk test [6MWT]) and symptom burden (Kansas City Cardiomyopathy Questionnaire) in 1,492 patients from the SURTAVI trial at baseline, 30Â days, 1 year, and 2 years. Patients were categorized by baseline functional status into tertiles of slow, medium, and fast walkers.
RESULTS
Patients with lowest capacity baseline functional status were commonly women, had higher Society of Thoracic Surgeons scores, and had more New York Heart Association functional class III or IV symptoms; reduced baseline functional status was associated with higher aortic valve- and heart failure-related hospitalization at 2 years. There was greater improvement in 6MWT distance in TAVR compared with surgery patients at 30Â days (PÂ < 0.001) and 1 year (PÂ =Â 0.012), but at 2 years, both groups had similar improvement (P = 0.091). The percentage of patients with large improvement in 6MWT was greatest in patients categorized as slow walkers and lowest in fast walkers. Symptom burden improved after TAVR at 30Â days and after both procedures at 1 and 2 years.
CONCLUSIONS
In this substudy of patients from the SURTAVI trial, patients receiving TAVR demonstrated a more rapid improvement in functional status and symptom burden compared with patients undergoing surgery; however, both groups had similar improvements in long-term follow-up.
