Creating and Maintaining a Community Literacy Project in Northwest Arkansas

The purpose of this research is to examine both logistical and curricular strategies employed by students and staff working with the Razorback Writers project as well as student productions in order to determine which of these strategies lead to the highest level of student participation in literacy-based activities, improvement in reading comprehension and writing abilities, and enjoyment of diverse texts

International perspectives on retention and persistence

Access to higher education globally is increasing dramatically; attainment of tertiary degrees is a high priority, as educational attainment is associated with increased personal incomes as well as growth of the middle class in developing countries. The purpose of this essay is to briefly examine retention and persistence issues from a global perspective, review some retention strategies that have been employed at schools outside the United States, and to identify several key factors that related to retention and persistence globally, including access, infrastructure, financial consideration, and readiness for tertiary education. There exists an opportunity to utilize knowledge gained in the evolution of the higher education system in the United States to help address the problems associated with retention and persistence.

Predictors of benefit following pulmonary rehabilitation for interstitial lung disease

SummaryBackgroundPulmonary rehabilitation improves functional capacity and symptoms in the interstitial lung diseases (ILDs), however there is marked variation in outcomes between individuals. The aim of this study was to establish the impact of the aetiology and severity of ILD on response to pulmonary rehabilitation.MethodsForty-four subjects with ILD, including 25 with idiopathic pulmonary fibrosis (IPF), underwent eight weeks of pulmonary rehabilitation. Relationships between disease aetiology, markers of disease severity and response to pulmonary rehabilitation were assessed after eight weeks and six months, regardless of program completion.ResultsIn IPF, greater improvements in 6-minute walk distance (6MWD) immediately following pulmonary rehabilitation were associated with larger forced vital capacity (r = 0.49, p = 0.01), less exercise-induced oxyhaemoglobin desaturation (rS = 0.43, p = 0.04) and lower right ventricular systolic pressure (r = −0.47, p = 0.1). In participants with other ILDs there was no relationship between change in 6MWD and baseline variables. Less exercise-induced oxyhaemoglobin desaturation at baseline independently predicted a larger improvement in 6MWD at six month follow-up. Fewer participants with IPF had clinically important reductions in dyspnoea at six months compared to those with other ILDs (25% vs 56%, p = 0.04). More severe dyspnoea at baseline and diagnosis other than IPF predicted greater improvement in dyspnoea at six months.ConclusionsPatients with IPF attain greater and more sustained benefits from pulmonary rehabilitation when disease is mild, whereas those with other ILDs achieve benefits regardless of disease severity. Early referral to pulmonary rehabilitation should be considered in IPF

Polo-like kinase 4 controls centriole duplication but does not directly regulate cytokinesis.

Centrioles organize the centrosome, and accurate control of their number is critical for the maintenance of genomic integrity. Centrioles duplicate once per cell cycle, and duplication is coordinated by Polo-like kinase 4 (Plk4). We previously demonstrated that Plk4 accumulation is autoregulated by its own kinase activity. However, loss of heterozygosity of Plk4 in mouse embryonic fibroblasts has been proposed to cause cytokinesis failure as a primary event, leading to centrosome amplification and gross chromosomal abnormalities. Using targeted gene disruption, we show that human epithelial cells with one inactivated Plk4 allele undergo neither cytokinesis failure nor increase in centrosome amplification. Plk4 is shown to localize exclusively at the centrosome, with none in the spindle midbody. Substantial depletion of Plk4 by small interfering RNA leads to loss of centrioles and subsequent spindle defects that lead to a modest increase in the rate of cytokinesis failure. Therefore, Plk4 is a centriole-localized kinase that does not directly regulate cytokinesis

Impaired chronotropic response to 6-min walk test and reduced survival in interstitial lung disease

SummaryBackgroundReduced chronotropic response to maximal exercise has been associated with poor survival in people without respiratory disease. The contribution of chronotropic response to exercise limitation and survival in interstitial lung disease (ILD) is not well defined. This study investigated the relationships between chronotropic response during 6-min walk test, exercise capacity and survival in ILD.MethodsEligible participants had ILD, were ambulant and free of heart failure and beta blocker therapy. Chronotropic response during the 6-min walk test was defined as peak heart rate (HR) minus resting HR. Survival was recorded at four years.ResultsSixty-two participants (40 idiopathic pulmonary fibrosis) were included, with mean (SD) TLCO 50(18)% predicted and 6-min walk distance (6MWD) 377 (127) metres. A smaller chronotropic response was associated with reduced 6MWD (r = 0.65, p < 0.001). Independent predictors of 6MWD were chronotropic response, peak oxygen uptake on cardiopulmonary exercise test; right ventricular systolic pressure on echocardiogram; and age. This model explained 83% of the variance in 6MWD, with 24% of the variance attributable to chronotropic response. A chronotropic response during 6-min walk test of less than 20 beats per minute was an independent predictor of death at four years (odds ratio 10.71, 95% confidence interval 2.67–42.94) in a model that also included oxygen desaturation and forced vital capacity.ConclusionsImpaired chronotropic response to 6-min walk test is associated with reduced 6MWD and reduced survival in ILD, independent of physical fitness and pulmonary hypertension. Investigation of the mechanisms underlying attenuated HR response to exercise in ILD is warranted

An institutional approach to developing a culture of student persistence

There continues to be increasing focus on college student retention and persistence. This focus is coming from the United States federal government, accrediting organizations, and from students, parents, and the public. Given the spiraling costs of education and the fact that retention rates have not improved over time, various stakeholders are concerned about the value of a higher education credential. The purpose of this manuscript is to describe the efforts of a for-profit, distance education institution to focus its resources, in an evidence-based manner, on retention and to develop a culture of retention and persistence throughout the institution. The literature review and analysis of internal initiatives demonstrated that (a) institutions must make a commitment to retention, include retention efforts as part of its strategic plan, and provide resources to support retention efforts; (b) mastery of knowledge of the research on retention and persistence is critical for designing evidence-based interventions; and (c) institutions should identify, develop, and implement pilot projects aimed at improving student progress and share results to help stimulate development of best practices throughout higher education.DOI: 10.18870/hlrc.v3i3.12

Haemophagocytic lymphohistiocytosis: A fulminant syndrome associated with multiorgan failure and high mortality that frequently masquerades as sepsis and shock

Acquired haemophagocytic lymphohistiocytosis (HLH) is a condition involving cytokine overproduction by defective cytotoxic T lymphocytes and natural killer cells, resulting in life-threatening cytopenias and multiorgan infiltration and dysfunction. Triggers for acquired HLH vary and include viruses, malignancies and autoimmune conditions. Recent reports suggest that HLH may be underdiagnosed owing to variable clinical presentations, diagnostic criteria and a low level of awareness on the part of medical personnel, thus delaying prompt treatment and contributing to high mortality rates. Five patients in whom acquired HLH was diagnosed, following bone marrow investigations, for the period of May - September 2013 are presented. All were at an advanced stage of their disease at time of diagnosis. The three patients who were HIV-positive had a coexisting malignancy at the time of HLH diagnosis, which may have triggered HLH. A definite trigger was not identified in the remaining two HIV-negative patients despite early concerns regarding autoimmune disease. Two patients received timeous diagnosis, started chemotherapy and are currently improving. The remaining three succumbed to their illness. Adult acquired HLH may be more common in the acute care setting than currently appreciated. As awareness of this condition and its treatment is currently low, it may remain undiagnosed until the disease has evolved into multiorgan failure. Fever in the absence of infectious agents, marked hyperferritinaemia, unexplained cytopenias, organomegaly or liver dysfunction should raise the suspicion of HLH. Timeous introduction of therapy will improve outcomes

Small Schools: Great Strides, A Study of New Schools in Chicago

This book documents a two-year study and analysis of small schools in Chicago. Using a mixed-method study, gathering both quantitative and qualitative data, the research serves to compare results to previous studies of small urban schools.The study examines the effects of small schools on students, parents, teachers, and community members. Both previous and current research suggest that small school size is correlated with an increase in student attendance, performance, and better sense of community overall.https://educate.bankstreet.edu/books/1022/thumbnail.jp
