Tailored instructional methods for students with diverse levels of computer knowledge and skills

The purpose of this online course is to ensure new nursing graduate students know how to use computer technologies required to complete academic and research activities. Powerful computers, high speed internet, digitalized resources and databases are widely available in educational institutes. New renovation and updates are being released at faster pace than ever. All these developments are necessary for a student to utilize computer programs and synthesize large amount of data in a limited time for any given academic research project.

Factors affecting ozone related asthma responses among middle school students with asthma

Outdoor environmental risk factors for asthma have been extensively researched, even though the majority of a person's daily activity occurs indoors. There is limited evidence linking personal exposure concentrations of ozone, pollen, mold, temperature, and humidity to childhood asthma. ^ The current study consisted of a secondary, more complex analysis of the data from the Houston Air Toxics and Asthma in Children (ATAC) Study to further investigate the association of personal ozone exposure on asthma outcome variability among middle school children with asthma. The ATAC Study primarily investigated the association between selected oxygenated air toxics and indicators of asthma variability (PEFR, FEV1, asthma symptoms, and rescue medication usage) among 30 labile and persistent Houston middle-school children with diagnosed asthma. This panel study used a repeated measurements design of four separate 10-day sampling periods that extended over a 20 month period. The secondary analysis included aggregate regression models that were constructed with two different estimates of ozone exposure (daily maximum hourly outdoor concentration and daily maximum hourly personal exposure), with three different estimates of personal environmental temperature and humidity exposures (daily average, intraday difference, and interday difference), and for thee different time periods [same day of exposure (lag 0), one day after initial exposure (lag 1), and two days after initial exposure (lag 2)]. ^ Overall, the models using daily maximum hourly personal ozone exposures in combination with intraday and interday personal temperature and humidity differences produced more significant plausible associations than models using daily maximum hourly personal ozone exposures with personal average temperature and humidity exposures. Significant associations were identified between daily maximum hourly personal ozone exposure and clinical indicators of asthma variability. The increasing effect on rescue medication usage from daily maximum hourly personal ozone exposure were identified as soon as the same day of exposure (lag 0; p=0.0072), and the same effects were delayed until the second next day (lag 2; p= 0.0026). The increasing effect on asthma symptoms were identified on the second next day after initial exposure (lag 2; p= 0.0024). There was a consistent inverse relationship between personal relative humidity exposure and indicators of asthma variability. Decreasing effects on daily FEV1 variability from personal relative humidity exposure were identified on the same day of exposure (lag 0; p= 0.034), increasing effects on morning PEFR were identified on the next day after initial exposure (lag 1; p= 0.0001), and decreasing effects on overnight PEFR variability were identified on the second next day after the initial exposure (lag 2; p= 0.007). With the conclusion of this research, there are opportunities for future similar studies in the preventive management of asthma in children living in high-ozone areas.^

Intellectual disability: A quandary for immigration

Current immigration options for individuals with intellectual disabilities do not adequately address their special needs and under existing immigration laws, intellectually disabled adult dependents of United States citizens suffer an excessive burden. This problem causes undue hardship of persons whose families lawfully reside in the United States or have the opportunity to immigrate to the United States. The aim of this review is to examine materials relevant to the issue and answer the question: What are the barriers and pathways for adults with intellectual disability within the family-based preference system under United States immigration law? ^ Adults with intellectual disability are a vulnerable population that often relies upon family members to be their principle caregiver and provide financial support. Under the family-based preference system, the United States has maintained that the reunion of family members with their close relatives promotes the health and welfare of the United States, but a review of the number of findings of inadmissibility due to a mental/physical disorder with associated harmful behavior and the number of waivers granted show otherwise. The lack of reviewability of the decisions made by the Board of Immigration Appeals in addition to the lack of transparency surrounding the immigration process only serve to compound this problem. ^

Variation of genotype and prevalence of Noro virus in U.S. students in Mexico with Traveler's Diarrhea, summer of 2004 and 2005

Noro virus, a positive single stranded RNA virus has been identified as a major etiologic agent in food borne gastroenteritis and diarrheal diseases. The emergence of this organism as a major non-bacterial cause in such outbreaks is partly due to the improved diagnostic tools like Reverse Transcription Polymerase chain reaction (RTPCR) that enable its detection. Noro virus accounts for nearly 96% of non-bacterial gastroenteritis outbreaks in US (1). Travelers' Diarrhea (TD) has remained a constant public health risk in the developed nations for decades and bacteria like Entero toxigenic Escherichia coli, Entero aggregative Escherichia coli have been described as the main etiologic agents for TD (2-4). A possible viral contribution to TD has been discovered in two studies (5, 6). The current study was designed to determine the prevalence of Noro virus in a population of 107 US students with TD acquired in Mexico in 2005 and to compare the prevalence to the prevalence of Noro virus in a similar study done in 2004. This study involved the testing of clinical stool specimens from 107 subjects in 2005 for the presence of Noro virus using RTPCR. The prevalence of Noro virus in 2004 used for comparison to 2005 data was obtained from published data (5). All subjects were recruited as TD subjects in a randomized, double-blinded clinical trial comparing a standard three day dosing of Rifaximin with and without an anti motility drug Loperamide. The prevalence of Noro virus geno group I was similar in both years, but geno group II prevalence differed across the two years (p = 0.003). This study finding suggests that the prevalence of Noro virus geno groups varies with time even within a specific geographic location. This study emphasizes the need for further systematic epidemiologic studies to determine the molecular epidemiology and the prevalence patterns of different geno groups of this virus. These are essential to planning and implementation of public health measures to lessen the burden of TD due to Noro virus infection among US travelers. ^
