Skunk River Review 2007-08, vol 20

Welcome to the 2007-2008 edition of The Skunk River Review! Each year we continue to receive many tremendous examples of student writing. Selection is a challenging process, but enjoyable as the submissions range from variety of topics and styles. Selected entries were only minimally edited for clarity. The Skunk River Review focuses on students from various DMACC campuses and includes three separate categories of writing from College Preparatory Writing and Composition I and Composition II classes. All entries generally begin as class assignments and are supported by the instructor.https://openspace.dmacc.edu/skunkriver/1000/thumbnail.jp

Hospital admissions from a pediatric HIV care and treatment program in Malawi

BackgroundThe scale up of pediatric antiretroviral treatment programs across Sub-Saharan Africa over the last decade has brought increasing numbers of children into HIV care. This patient population requiring life-long care presents new challenges in the outpatient and inpatient settings. We sought to describe hospitalizations from a large pediatric HIV treatment facility to better understand the scope of the situation and identify areas for improved care delivery.MethodsWe conducted a retrospective case series of all HIV-infected and exposed patients <18 years enrolled at Baylor College of Medicine Children's Foundation Malawi, from October 2004-October 2010. Patients admitted to the hospital on or after the day of enrollment were included. Data were extracted from electronic clinic records. Analysis was done at the patient and admission level, as some patients had multiple admissions.ResultsOf 5062 patients enrolled in care, 877 (17.3 %) had 1137 admissions at median age 24 months (IQR: 12-62). 191 (21.8 %) patients had multiple admissions. A high proportion of admissions occurred in patients under two years (49.4 %), those within one month of clinic enrollment (32.9 %), those with severe immune suppression (44.0 %), and those not on ART (48.5 %). The frequency of primary admission diagnoses varied across these same variables, with malnutrition, pneumonia, and malaria being the most common.ConclusionsIllness requiring hospitalization is common in HIV-infected and exposed children and these results reinforce the need for a comprehensive care package with special attention to nutrition. Strengthened programs for malaria prevention and expanded access to pneumococcal vaccine are also needed. The high burden of admissions in children under 24 months and those newly enrolled in care suggests a need for continued improvement of early infant diagnosis and provider-initiated testing programs to link patients to care before they are symptomatic. Similarly, the high proportion of admissions in those not yet started on ART emphasizes the importance of rapid initiation of ART for eligible pediatric patients

Oleds for General Lighting

The goal of this program was to reduce the long term technical risks that were keeping the lighting industry from embracing and developing organic light-emitting diode (OLED) technology for general illumination. The specific goal was to develop OLEDs for lighting to the point where it was possible to demonstrate a large area white light panel with brightness and light quality comparable to a fluorescence source and with an efficacy comparable to that of an incandescent source. it was recognized that achieving this would require significant advances in three area: (1) the improvement of white light quality for illumination, (2) the improvement of OLED energy efficiency at high brightness, and (3) the development of cost-effective large area fabrication techniques. The program was organized such that, each year, a ''deliverable'' device would be fabricated which demonstrated progress in one or more of the three critical research areas. In the first year (2001), effort concentrated on developing an OLED capable of generating high illumination-quality white light. Ultimately, a down-conversion method where a blue OLED was coupled with various down-conversion layers was chosen. Various color and scattering models were developed to aid in material development and device optimization. The first year utilized this approach to deliver a 1 inch x 1 inch OLED with higher illumination-quality than available fluorescent sources. A picture of this device is shown and performance metrics are listed. To their knowledge, this was the first demonstration of true illumination-quality light from an OLED. During the second year, effort concentrated on developing a scalable approach to large area devices. A novel device architecture consisting of dividing the device area into smaller elements that are monolithically connected in series was developed. In the course of this development, it was realized that, in addition to being scalable, this approach made the device tolerant to the most common OLED defect--electrical shorts. This architecture enabled the fabrication of a 6 inch x 6 inch OLED deliverable for 2002. A picture of this deliverable is shown and the performance metrics are listed. At the time, this was the highest efficiency, highest lumen output illumination-quality OLED in existence. The third year effort concentrated on improving the fabrication yield of the 6 inch x 6 inch devices and improving the underlying blue device efficiency. An efficiency breakthrough was achieved through the invention of a new device structure such that now 15 lumen per watt devices could be fabricated. A 2 feet x 2 feet OLED panel consisting of sixteen 6 inch x 6 inch high efficiency devices tiled together was then fabricated. Pictures of this panel are shown with performance metrics listed. This panel met all project objectives and was the final deliverable for the project. It is now the highest efficiency, highest lumen output, illumination-quality OLED in existence

A Two One-Sided Parametric Tolerance Interval Test for Control of Delivered Dose Uniformity. Part 1—Characterization of FDA Proposed Test

The FDA proposed a parametric tolerance interval (PTI) test at the October 2005 Advisory Committee meeting as a replacement of the attribute (counting) test for delivered dose uniformity (DDU), published in the 1998 draft guidance for metered dose inhalers (MDIs) and dry powder inhalers (DPIs) and the 2002 final guidance for inhalation sprays and intranasal products. This article (first in a series of three) focuses on the test named by the FDA “87.5% coverage.” Unlike a typical two-sided PTI test, which controls the proportion of the DDU distribution within a target interval (coverage), this test is comprised of two one-sided tests (TOST) designed to control the maximum amount of DDU values in either tail of the distribution above and below the target interval. Through simulations, this article characterizes the properties and performance of the proposed PTI-TOST under different scenarios. The results show that coverages of 99% or greater are needed for a batch to have acceptance probability 98% or greater with the test named by the FDA “87.5% coverage” (95% confidence level), while batches with 87.5% coverage have less than 1% probability of being accepted. The results also illustrate that with this PTI-TOST, the coverage requirement for a given acceptance probability increases as the batch mean deviates from target. The accompanying articles study the effects of changing test parameters and the test robustness to deviations from normality
