The Lived Experiences of Students and Faculty of a Christian College who Participated in a Short-term International Mission Trip

Short-term international mission trips (STIMTs) are increasing in popularity. Likewise, educators and health care workers are increasingly concerned with obtaining an understanding that improves culturally competent care. The purpose of this study was to investigate the lived experiences of participants of a Christian college who travelled on a short-term international mission trip (STIMT). One openended inquiry guided the interviews: How would you describe your experience as a participant who travelled on a STIMT? An in-depth, oneon- one interview of participants occurred until data saturation was reached. Colaizzi’s strategy was used to analyze and organize the data. Leininger’s sunrise model was used to guide this study. Themes that emerged from this study included cultural adaptation, relationships, spiritual factors, and personal gain

Relationships Effecting College Students’ Perception of Family Influence Impacting their Health and Lifestyle

The purpose of this cross-sectional, nonexperimental descriptive design study was to determine college students’ perception of family influence impacting their health and lifestyle. The sample included 120 college students in a faithbased institution and each student completed a Likert-type survey (4-point agreement scale) that investigated their perception of health, and the degree of influence peers and family had on their health. This second data analysis reports correlations between variables and group differences related to health perceptions and behaviours. The strongest correlation is between ‘family demonstration of positive health habits’ and ‘personal health practices being like my families’ (r = 0.671, p \u3c 0.01), a moderate relationship supported by other weaker positive correlations to specific health outcomes. Negative correlations between ‘my friends display more positive health habits than family’ and both ‘family has influenced my idea of health’ and ‘my health practices are similar to my family’ indicate the potential for other contextual factors to effect family impact. While differences relating to health influence and outcomes between groups formed by age, gender, ethnicity, family structure and religion were found, the variable related to most healthy lifestyle transmission elements was ‘My family demonstrates positive health habits’. Recommendations supporting improved societal health are offered, together with suggestions for further research. Group classifications that are fixed but might inform interactions with elements of cohorts are identified, together with group memberships which might be changed to enhance health options. Caution in the generalisation of these findings is advised due to the explained limitations of this study

Comparing the Fiscal Consequences of Controlled and Uncontrolled Osteoarthritis Pain Applying a UK Public Economic Perspective

**Background:** Individuals experiencing osteoarthritis (OA) pain can pose significant costs for governments due to reduced work activity in these individuals and increasing reliance on public support benefits. In this analysis we capture the broader economic impact of OA pain by applying a government perspective, public economic framework to assess controlled and uncontrolled pain. **Methods:** We used a Markov model to compare labour market participation in people with uncontrolled OA hip or knee pain compared to a cohort with controlled OA pain. The likelihood of employment, long-term sickness, disability, and early retirement in those with controlled pain used publicly available UK data. The relative effect of uncontrolled OA pain on fiscal outcomes is drawn from peer reviewed publications reporting reduced work activity and reliance on public benefits for people with uncontrolled OA pain. Lost tax revenue was derived using UK tax rates and national insurance contributions applied to annual earnings. Social benefit rules were applied to calculate government financial support to individuals. Health-care costs were calculated based on estimates from an UK observational study. The base case analysis compared the projected lost tax revenue and transfer payments for a 50-year-old cohort with severe OA pain, retiring at age 65. **Results:** For a 50-year-old individual with moderate uncontrolled OA pain with 15-years remaining work expectancy, the model estimated a £62 383 reduction in employment earnings, a £24 307 reduction in tax contributions and a need for £16 034 in government benefits, compared to a person with controlled OA pain. In people with severe uncontrolled OA pain incremental foregone earnings were estimated to be £126 384, £44 925 were not paid through taxation and £25 829 were received in public benefits, compared to the controlled pain cohort. Health-care costs represented 13% and 12% of all OA-related fiscal cost in the moderate uncontrolled OA pain and severe uncontrolled OA pain comparison, respectively. **Conclusions:** For governments, maintaining an active workforce is paramount to maintaining economic growth and reducing spending on government programs. The approach described here can be used to augment cost-effectiveness models to inform a range of stakeholders of benefits attributed to controlled OA pain

The peripheral blood transcriptome in septic cardiomyopathy: an observational, pilot study.

BACKGROUND:Septic cardiomyopathy (SCM) is common in sepsis and associated with increased morbidity and mortality. Left ventricular global longitudinal strain (LV GLS), measured by speckle tracking echocardiography, allows improved identification of impaired cardiac contractility. The peripheral blood transcriptome may be an important window into SCM pathophysiology. We therefore studied the peripheral blood transcriptome and LV GLS in a prospective cohort of patients with sepsis. RESULTS:In this single-center observational pilot study, we enrolled adult patients (age > 18) with sepsis within 48 h of admission to the ICU. SCM was defined as LV GLS > - 17% based on echocardiograms performed within 72 h of admission. We enrolled 27 patients, 24 of whom had high-quality RNA results; 18 (75%) of 24 had SCM. The group was 50% female and had a median (IQR) age of 59.5 (48.5-67.0) years and admission APACHE II score of 21.0 (16.0-32.3). Forty-six percent had septic shock. After filtering for low-expression and non-coding genes, 15,418 protein coding genes were expressed and 73 had significantly different expression between patients with vs. without SCM. In patients with SCM, 43 genes were upregulated and 30 were downregulated. Pathway analysis identified enrichment in type 1 interferon signaling (adjusted p < 10-5). CONCLUSIONS:In this hypothesis-generating study, SCM was associated with upregulation of genes in the type 1 interferon signaling pathway. Interferons are cytokines that stimulate the innate and adaptive immune response and are implicated in the early proinflammatory and delayed immunosuppression phases of sepsis. While type 1 interferons have not been implicated previously in SCM, interferon therapy (for viral hepatitis and Kaposi sarcoma) has been associated with reversible cardiomyopathy, perhaps suggesting a role for interferon signaling in SCM

A proposed expert system for nursing practice

The knowledge on which nursing practice is based comes largely from traditional sources, expert nurses passing on the wisdom of their experience to novices. Nursing research, although increasing, is usually parallel to nursing practice, and its findings, at best, are implemented only after long delays. Consequently, the most effective nursing responses to a particular client problem may be undiscovered or unknown. Nursing information systems reflect the nature and usage of nursing knowledge. They offer standard care plans, but the knowledge and decision structures for individualizing care remain exclusively in the mind of the nurse. Nurses may have great freedom to enter information into the information system, but the information is rarely retrievable in a form suitable for evaluation or research. Nursing practice, and the knowledge on which it is based, could be enhanced through the use of a novel expert system. This paper describes how such a system could be developed, with examples from the authors' prototype programs. Taxonomies of data, diagnoses, objectives, and interventions would make it possible to compare patients and to determine the relative effectiveness of nursing interventions. A built-in evaluation component would provide feedback and correction. Everyday nursing practice would become a field for research, and the knowledge gained from research would immediately be fed back into practice. In its development and in its implementation, this kind of system would help to build nursing science.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45001/1/10916_2004_Article_BF00992522.pd

Geometric Phases and Mielnik's Evolution Loops

The cyclic evolutions and associated geometric phases induced by time-independent Hamiltonians are studied for the case when the evolution operator becomes the identity (those processes are called {\it evolution loops}). We make a detailed treatment of systems having equally-spaced energy levels. Special emphasis is made on the potentials which have the same spectrum as the harmonic oscillator potential (the generalized oscillator potentials) and on their recently found coherent states.Comment: 11 pages, harvmac, 2 figures available upon request; CINVESTAV-FIS GFMR 11/9

Prevalence of HIV among blood donors at Juba Teaching Hospital Blood Bank, South Sudan

Objectives: The aim of this study is to determine the prevalence of HIV among blood donors in Juba Teaching Hospital Blood Bank, South Sudan in 2013.Method and Materials: This is a retrospective study that involved the abstraction of data from registers at the blood bank. Data were collected onto data sheets and entered into a computer database. Statistical analysis was performed using SPSS Version 20 Software. A p value of <0.05 was considered statistically significant.Results: Out of 1095 blood donors, 1074 (98.1%) were males and 21 (1.9%) were females. The mean age and the range for the whole group was 29+7.16 (15-69) yrs. The prevalence of HIV was higher among males than females 85 (7.9%) vs 1 (4.8%) respectively but this was not statistical significant (p=0.6). The 20 to 29 year age group had the highest prevalence of 49 (57%) with no statistical significance (p=0.3). The prevalence of HIV was 7. % (86) and there were co-infections between HIV and HBV, HCV and syphilis of14 (50%), 5 (18%), 9 (32%) with p=0.7, p=0.1, p=0.8 respectively. Blood group O positive had the highest percentage 58.1 % (n=50) and was the commonest group.Conclusion: In this study, HIV prevalence is very high among blood donors at the Juba Teaching Hospital blood bank

Indoor residual spraying with a non-pyrethroid insecticide reduces the reservoir of <i>Plasmodium falciparum</i> in a high-transmission area in northern Ghana

High-malaria burden countries in sub-Saharan Africa are shifting from malaria control towards elimination. Hence, there is need to gain a contemporary understanding of how indoor residual spraying (IRS) with non-pyrethroid insecticides when combined with long-lasting insecticidal nets (LLINs) impregnated with pyrethroid insecticides, contribute to the efforts of National Malaria Control Programmes to interrupt transmission and reduce the reservoir of Plasmodium falciparum infections across all ages. Using an interrupted time-series study design, four age-stratified malariometric surveys, each of ~2,000 participants, were undertaken pre- and post-IRS in Bongo District, Ghana. Following the application of three-rounds of IRS, P. falciparum transmission intensity declined, as measured by a >90% reduction in the monthly entomological inoculation rate. This decline was accompanied by reductions in parasitological parameters, with participants of all ages being significantly less likely to harbor P. falciparum infections at the end of the wet season post-IRS (aOR = 0.22 [95% CI: 0.19–0.26], p-value < 0.001). In addition, multiplicity of infection (MOIvar) was measured using a parasite fingerprinting tool, designed to capture within-host genome diversity. At the end of the wet season post-IRS, the prevalence of multi-genome infections declined from 75.6% to 54.1%. This study demonstrates that in areas characterized by high seasonal malaria transmission, IRS in combination with LLINs can significantly reduce the reservoir of P. falciparum infection. Nonetheless despite this success, 41.6% of the population, especially older children and adolescents, still harboured multi-genome infections. Given the persistence of this diverse reservoir across all ages, these data highlight the importance of sustaining vector control in combination with targeted chemotherapy to move high-transmission settings towards pre-elimination. This study also points to the benefits of molecular surveillance to ensure that incremental achievements are not lost and that the goals advocated for in the WHO’s High Burden to High Impact strategy are realized

Silencing Early Viral Replication in Macrophages and Dendritic Cells Effectively Suppresses Flavivirus Encephalitis

West Nile (WN) and St. Louis encephalitis (SLE) viruses can cause fatal neurological infection and currently there is neither a specific treatment nor an approved vaccine for these infections. In our earlier studies, we have reported that siRNAs can be developed as broad-spectrum antivirals for the treatment of infection caused by related viruses and that a small peptide called RVG-9R can deliver siRNA to neuronal cells as well as macrophages. To increase the repertoire of broad-spectrum antiflaviviral siRNAs, we screened 25 siRNAs targeting conserved regions in the viral genome. Five siRNAs were found to inhibit both WNV and SLE replication in vitro reflecting broad-spectrum antiviral activity and one of these was also validated in vivo. In addition, we also show that RVG-9R delivers siRNA to macrophages and dendritic cells, resulting in effective suppression of virus replication. Mice were challenged intraperitoneally (i.p.) with West Nile virus (WNV) and treated i.v. with siRNA/peptide complex. The peritoneal macrophages isolated on day 3 post infection were isolated and transferred to new hosts. Mice receiving macrophages from the anti-viral siRNA treated mice failed to develop any disease while the control mice transferred with irrelevant siRNA treated mice all died of encephalitis. These studies suggest that early suppression of viral replication in macrophages and dendritic cells by RVG-9R-mediated siRNA delivery is key to preventing the development of a fatal neurological disease

Jet-Launching Structure Resolved Near the Supermassive Black Hole in M87

Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by the accretion of matter onto supermassive black holes. Although the measured width profiles of such jets on large scales agree with theories of magnetic collimation, the predicted structure on accretion disk scales at the jet launch point has not been detected. We report radio interferometry observations, at a wavelength of 1.3 millimeters, of the elliptical galaxy M87 that spatially resolve the base of the jet in this source. The derived size of 5.5 ± 0.4 Schwarzschild radii is significantly smaller than the innermost edge of a retrograde accretion disk, suggesting that the M87 jet is powered by an accretion disk in a prograde orbit around a spinning black hole
