North Park University is a four-year university located at 3225 W. Foster Avenue on the north side of Chicago, Illinois in the North Park neighborhood. It was founded in 1891 by the Evangelical Covenant Church and shares its campus with the denomination's only seminary. The university enrolls more than 3,000 students from around the country and the world and offers bachelors and master's degrees. Wikipedia.

Pluto's icy surface has changed colour and its atmosphere has swelled since its last closest approach to the Sun in 1989. The thin atmosphere is produced by evaporating ices, and so can also change rapidly, and in particular carbon monoxide should be present as an active thermostat. Here we report the discovery of gaseous CO via the 1.3-mm wavelength J=2-1 rotational transition, and find that the line-centre signal is more than twice as bright as a tentative result obtained in 2000 by Bockélee-Morvan et al. Greater surface ice evaporation over the last decade could explain this, or increased pressure could have caused the atmosphere to expand. The gas must be cold, with a narrow line-width consistent with temperatures around 50 K, as predicted for the very high atmosphere, and the line brightness implies that CO molecules extend up to ≈3 Pluto radii above the surface. The upper atmosphere must have changed markedly over only a decade since the prior search, and more alterations could occur by the arrival of the New Horizons mission in 2015. © 2011 The Authors Monthly Notices of the Royal Astronomical Society. © 2011 RAS.

OBJECTIVES:: (1) To examine the prevalence of diagnosis and treatment for constipation among children receiving Medicaid. (2) To compare healthcare utilization and spending for constipation among children based on number of complex chronic conditions (CCCs). METHODS:: Retrospective cohort study of 4.9 million children aged 1 to 17 years enrolled in Medicaid from 2009–2011 in 10 states in the Truven Marketscan® Database. Constipation was identified using ICD-9 codes for constipation (564.0x), intestinal impaction (560.3x) or encopresis (307.7). Outpatient and inpatient utilization and spending for constipation were assessed. CCC status was identified using validated methodology. RESULTS:: 267,188 children (5.4%) were diagnosed with constipation. Total constipation spending was $79.5 million. Outpatient constipation spending was $66.8 million (84.1%) over 406,814 visits, mean spending $120/visit. Among children with constipation, 1,363 (0.5%) received inpatient treatment, accounting for $12.2 million (15.4%) of constipation spending, mean spending $7,815/hospitalization. Of children hospitalized for constipation, 552 (40.5%) did not have an outpatient visit for constipation prior to admission. 6.8% of children in the study had?>?1 CCC; these children accounted for 33.5% of total constipation spending, 70.3% of inpatient constipation spending, and 19.8% of emergency department (ED) constipation spending. Constipation prevalence was 11.0% for children with 1 CCC, 16.6% with 2 CCCs and 27.1% with ≥3 CCCs. CONCLUSIONS:: Although the majority of pediatric constipation treatment occurs in the outpatient setting, inpatient care accounts for a sizable percentage of spending. Children with CCCs have a higher prevalence of constipation and account for a disproportionate amount of constipation healthcare utilization and spending. © 2016 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology,

Progress in Materials Science | Year: 2013
The physical basis for the Frank-Bilby equation is considered. Dual descriptions in terms of interface physics and mechanics are introduced. Natural (NDP), commensurate (CDP) and rotated (RCDP) dichromatic patterns are introduced. Burgers vectors are defined by symmetry operations or circuits in the CDP and RCDP. Structures are described for misfit arrays, tilt arrays, twist arrays, disconnections and combinations of these defects. The concepts of partitioning of elastic distortions, array energies, node formation, and the lateral spreading of defects within interfaces are considered. Examples with analytical solutions, numerical solutions and iterative solutions are presented. We elucidate some principles that emerge from the solutions and present reasons why some results differ from other methods of analysis. © 2012 Elsevier Ltd.

The diagnosis of drug-induced liver injury (DILI) is largely a diagnosis of exclusion because, with the possible exception of protein:drug adducts in paracetamol overdose, there are no laboratory, biopsy or imaging tests that alone are capable of establishing an unequivocal diagnosis of DILI. However, it is increasingly appreciated that drugs that cause DILI typically have characteristic clinical presentations or 'signatures' that can be very useful in the diagnosis of DILI. Indeed, knowing a drug's DILI signature (or sometimes signatures) and the incidence rate of DILI during treatment with that drug are perhaps the most useful pieces of historical information in arriving at the diagnosis of DILI. Components of the signature include the typical latency from the onset of treatment, whether there are extrahepatic manifestations, whether the injury is hepatocellular, cholestatic or mixed, and sometimes characteristic features on biopsy or serological testing (e.g. liver autoantibodies). A major advance has been the establishment of the LiverTox website (http://livertox.nih.gov/) which provides open access to standardized entries for over 600 different drugs, including the characteristic clinical presentations of DILI when known. LiverTox will also calculate the causality score for individual cases using the RUCAM instrument and case-specific data entered by the site user. However, the problem with standard diagnostic instruments such as the RUCAM is that DILI signatures are not incorporated into the scoring system. The person entering data must therefore subjectively weigh the RUCAM score with the characteristic DILI signature(s) of the drug to arrive at a diagnosis. In the future, it should be possible to construct improved diagnostic instruments that objectively incorporate DILI signatures, data-based estimates of the incidence rates of DILI from each implicated drug, and perhaps genetic variants associated with the risk of DILI. © 2015 S.

Workplace Health and Safety | Year: 2013
Workplace stress within health care settings is rampant and predicted to increase in coming years. The profound effects of workplace stress on the health and safety of nursing personnel and the financial impact on organizations are well documented. Although organizational modification can reduce some sources of stress, several unique stress-producing factors inherent in the work of nursing personnel are immutable to such approaches. Mindfulness training, an evidencebased approach to increase situational awareness and positive responses to stressful situations, is an inexpensive strategy to reduce stress and improve the quality of nurses' work lives. Several approaches to training, such as mindfulness- based stress reduction, can be tailored to health care settings. Considerations for occupational health nurses in incorporating mindfulness training as an aspect of a comprehensive work site health promotion program for nursing and other hospital personnel are discussed.
