The suppression of the RAS by the blockade of angiotensin II type 1 (AT(1)) receptors may demonstrate remodeling effects on the ubiquitous small resistance vessels similar to that seen in the myocardium and renal glomeruli, thus affording more complete end-organ protection.

he Intermittent Exotropia Questionnaire (IXTQ) is a patientderived, intermittent exotropia-specific instrument designed to evaluate health-related quality of life (HRQOL) in children with intermittent exotropia and their parents. 1,2 The IXTQ consists of 3 parts: the 12-item child IXTQ (completed by the child to assess the child's HRQOL), the 12-item proxy IXTQ (completed by the parent to assess the child's HRQOL), and the 17-item parent IXTQ (completed by the parent regarding his or her own HRQOL). 1 The child and proxy questionnaires each have a single subscale. The parent questionnaire contains 3 subscales: psychosocial, function, and surgery. The IXTQ is reliable and valid for assessing HRQOL in children with intermittent exotropia. [1][2][3] It is available for download free of charge at http://pedig.jaeb.org/.The IXTQ was originally developed using classical test theory. Rasch analysis may be used to modify and improve existing HRQOL instruments. [4][5][6][7][8][9] In the present study, Rasch analysis was used to refine the existing IXTQ, removing items that do not contribute meaningful information to the instrument and ensuring that response options are properly interpreted. Methods Patient CohortParents gave written informed consent, and children gave written assent when required. The protocol was approved by the institutional review boards of the Mayo Clinic, Jaeb Center for Health Research, and other local sites involved in the study. Data were collected and analyzed in accordance with the Health Insurance Portability and Accountability Act guidelines. The IXTQ was completed by 575 parents of 575 children aged 1 through 16 years with intermittent exotropia at the time of their child's clinic examination, enrolled from May 15, 2008, through July 24, 2013. The 295 children aged 5 years or older completed the age-appropriate child IXTQ. Parents and children completed the IXTQ as part of routine care in the strabismus practice of one of the authors (J.M.H., n = 110) or at the enrollment examination for 1 of 2 ongoing randomized clinical trials being conducted by the Pediatric Eye Disease Investigator Group (NCT 01032603 [n = 69] and NCT 01032330 [n = 396]). Child questionnaires were administered to children aged 5 through 7 years by study personnel. All 8-to 17-year-old child, proxy, and parent questionnaires were self-administered. Patient demographics are reported in eTable 1 in the Supplement. Statistical AnalysisBefore Rasch analysis, items with floor and ceiling effects on the child, proxy, and parent IXTQs were eliminated as described in the eMethods in the Supplement. Rasch analysis was performed on each of the 4 IXTQs using the analytic methods that we have applied previously (eMethods in the Supplement). 9 The performance and structure of the Rasch-IMPORTANCE The Intermittent Exotropia Questionnaire (IXTQ) is a patient, proxy, and parental report of quality of life specific to children with intermittent exotropia. We refine the IXTQ using Rasch analysis to improve reliability and validity.OBSERVATI...

Background: Creating a curriculum that can effectively develop critical thinking skills is an elusive outcome for undergraduate nursing programs. Despite the best efforts of faculty, employers continue to note an inability of new graduates to apply critical thinking concepts that improve patient outcomes. The lack of an operational definition of critical thinking appears to be a key contributor to this issue. Method: A concept analysis was developed to identify a definition of critical thinking that allows for clear, measurable learning outcomes. Results: Despite extensive discussion within the literature, a consistent definition of critical thinking is lacking; instead, a rather extensive list exists of the attributes and antecedents consistently found in individuals who think critically. Conclusion: Curricular student learning outcomes framed around operational attributes can promote the development of critical thinking skills and improve patient outcomes.
