Rita Dove: 03-06-1985
Dove discusses her fascination with the unseen and insignificant details of historical events and individual lives. This interest in the less celebrated moments of experience shaped Museum and Thomas and Beulah. Her careful attention to language, form, structure, and organization in her work is revealed throughout the interview. She talks about the crafting of Parsley as well as the organization of the Museum. Dove says she doesn\u27t want the reader to know what is coming in a book. She says the worst thing that can happen to a poet is to be self-conscious because it interferes with the creative process. She tries not to clutter her head with too much literary critique and theory, particularly when she is composing.

Perceived Influence of Lecturersâ Rating of Accreditation Exercise on Quality Assurance in Universities in South East States, Nigeria
This study examined perceived influence of lecturersâ ratings of accreditation exercise on quality assurance in universities in south east states in Nigeria. The study was carried out using two research questions and two hypotheses. The research design adopted for the study is a descriptive survey design which involved inferential approach. The population of the study comprise 3,843 members of academic staff of the five public state owned universities in south east geo-political zone of Nigeria. The sample for this study is 384 academic staff from the five state universities in the South East Geo-Political Zone of Nigeria. Proportionate cluster random sampling technique was used as the sampling technique for this study. The instrument used for collecting the data for the study is a rating scale titled: âExtent of Accreditation Exercise Influence on Quality Assurance Scale (EAEIQAS)â. The instrument was validated by two experts in Measurement and Evaluation and three experts in Educational Management. The reliability index of 0.80 was gotten for the instrument using Cronbach alpha statistics. The research questions were answered using mean score and standard deviation statistics while the hypotheses were tested using one sample t-test statistics at 0.05 level of significance. The major findings are that the lecturersâ ratings of accreditation exercise on academic content of state universities in South East is high and significantly above average, and the ratings of accreditation exercise on staffing of state universities in South East is high and significantly above average. Based on the findings, it was recommended among others that the universities should improve more on their academic content as this will help to inculcate the required academic knowledge and skills to her graduates as a sign of quality indicator
Factors associated with spontaneous clearance of chronic hepatitis C virus infection
Background & Aims:
Spontaneous clearance of chronic hepatitis C virus (HCV) infection (CHC) is rare. We conducted a retrospective case-control study to identify rates and factors associated with spontaneous clearance of CHC.
Methods:
We defined cases as individuals who spontaneously resolved CHC, and controls as individuals who remained chronically infected. We used data obtained on HCV testing between 1994 and 2013 in the West of Scotland to infer case/control status. Specifically, untreated patients with â©Ÿ2 sequential samples positive for HCV RNA â©Ÿ6Â months apart followed by â©Ÿ1 negative test, and those with â©Ÿ2 positive samples â©Ÿ6Â months apart with no subsequent negative samples were identified. Control patients were randomly selected from the second group (4/patient of interest). Case notes were reviewed and patient characteristics obtained.
Results:
25,113 samples were positive for HCV RNA, relating to 10,318 patients. 50 cases of late spontaneous clearance were identified, contributing 241 person-years follow-up. 2,518 untreated, chronically infected controls were identified, contributing 13,766 person-years follow-up, from whom 200 controls were randomly selected. The incidence rate of spontaneous clearance was 0.36/100 person-years follow-up, occurring after a median 50Â monthsâ infection. Spontaneous clearance was positively associated with female gender, younger age at infection, lower HCV RNA load and co-infection with hepatitis B virus. It was negatively associated with current intravenous drug use.
Conclusions:
Spontaneous clearance of CHC occurs infrequently but is associated with identifiable host and viral factors. More frequent HCV RNA monitoring may be appropriate in selected patient groups.
Lay summary:
Clearance of hepatitis C virus infection without treatment occurs rarely once chronic infection has been established. We interrogated a large Scottish patient cohort and found that it was more common in females, patients infected at a younger age or with lower levels of HCV in the blood, and patients co-infected with hepatitis B virus. Patients who injected drugs were less likely to spontaneously clear chronic infection
A prospective study of the sensitivity, specificity and diagnostic performance of soluble intercellular adhesion molecule 1, highly sensitive C-reactive protein, soluble E-selectin and serum amyloid A in the diagnosis of neonatal infection
<p>Abstract</p> <p>Background</p> <p>Diagnosis of neonatal infection is difficult, because of it's non-specific clinical presentation and the lack of reliable diagnostic tests. The purpose of this study was to examine the potential diagnostic value of serum soluble intercellular adhesion molecule-1 (sICAM-1), soluble E-selectin (sE-selectin), highly sensitive C-reactive protein (hsCRP) and serum amyloid A (SAA) measurements, both individually and in combination in the setting of a neonatal intensive care unit.</p> <p>Methods</p> <p>219 consecutive serum samples were taken from 149 infants undergoing sepsis work up in a neonatal intensive care unit. Clinical diagnosis was established in a prospective manner, blind to the results of the study measurements. Infants were classified by an experienced paediatrician as infected or not-infected, one week after presentation. Classification was based on clinical presentation, routine laboratory and radiological investigations and response to therapy. The infected group were sub-classified as (a) culture positive infection or (b) culture negative infection. sICAM-1, sE-selectin, hsCRP and SAA levels were determined from stored serum samples after diagnosis was established. Further sub-group analysis of results was undertaken according to early or late onset of infection and preterm or term status. Statistical analysis utilised Mann Whitney U test and ROC curve analysis.</p> <p>Results</p> <p>There were significantly increased serum levels of sICAM-1, hsCRP, E selectin (p < 0.001) and SAA (p = 0.004) in infected infants compared with non-infected. ROC curve analysis indicated area under the curve values of 0.79 (sICAM-1), 0.73 (hsCRP), 0.72 (sE-selectin) and 0.61 (SAA). ROC curve analysis also defined optimum diagnostic cut-off levels for each measurement. The performance characteristics of sICAM-1, hsCRP and sE-selectin included a high negative predictive value (NPV) for culture positive infection and this was enhanced by combination of all 4 measurements. Clinical subgroup analysis suggested particularly high NPV for early onset symptoms, however further studies are required to elucidate this finding.</p> <p>Conclusions</p> <p>All four study measurements demonstrated some diagnostic value for neonatal infection however sICAM-1, hsCRP and sE-selectin demonstrated the highest NPV individually. The optimum diagnostic cut off level for hsCRP measurement in this study was much lower than currently used in routine clinical practice. Use of a combination of measurements enhanced diagnostic performance, demonstrating sensitivity of 90.3% and NPV of 91.3%. This study suggests there may be value in use of several of these markers, individually and in combination to assist in excluding neonatal infection. Further work is needed to confirm a specific role in the exclusion of early onset infection.</p
Analysis, characterization, and effects of heavy metal chealating agents in water
Students supported: 5 Student Assistants"The term 'chelating agents' refers to chemical ligands which bind to an element with more than one site. It is a ubiquitous term, since there are multitudes of compounds which fulfill the requirements for being called chelating agents. Their origin is both synthetic and natural, and the manner and fashion in which they bind is quite varied. Many of the vitamins and hormones essential to life are chelating agents. Chlorophyll, which is required for photosynthesis, consists of a porphyrin ring structure bound to magnesium. Hemoglobin binds iron in a similar pattern, and vitamin B-12 utilizes cobalt in the same fashion. In addition to these, there are quite a number of similar compounds in both plants and animals. Most metals transport and usage inside living things involve a chelation process. In natural water systems, the presence of chelating agents can have significant impact on the transport and toxicity of metals."--IntroductionProject # B-095-MO Agreement # 14-31-0001-409

Effect of Peer Education on Stroke Prevention: The Prevent Recurrence of All Inner-City Strokes Through Education Randomized Controlled Trial
Background and PurposeâEfforts to reduce disparities in recurrent stroke among Black and Latino stroke survivors have met with limited success. We aimed to determine the effect of peer education on secondary stroke prevention among predominantly minority stroke survivors.
MethodsâBetween 2009 and 2012, we enrolled 600 stroke or transient ischemic attack survivors from diverse, low-income communities in New York City into a 2-arm randomized clinical trial that compared a 6 week (1 session/week), peer-led, community-based, stroke prevention self-management group workshop (N=301) to a wait-list control group (N=299). The primary outcome was the proportion with a composite of controlled blood pressure (<140/90 mm Hg), low-density lipoprotein cholesterol <100 mg/dL, and use of antithrombotic medications at 6 months. Secondary outcomes included control of the individual stroke risk factors. All analyses were by intent-to-treat.
ResultsâThere was no difference in the proportion of intervention and control group participants achieving the composite outcome (34% versus 34%; P=0.98). The proportion with controlled blood pressure at 6 months was greater in the intervention group than in the control group (76% versus 67%; P=0.02). This corresponded to a greater change in systolic blood pressure in the intervention versus control group (â3.63 SD, 19.81 mm Hg versus +0.34 SD, 23.76 mm Hg; P=0.04). There were no group differences in the control of cholesterol or use of antithrombotics.
ConclusionsâA low-cost peer education self-management workshop modestly improved blood pressure, but not low-density lipoprotein cholesterol or antithrombotic use, among stroke and transient ischemic attack survivors from vulnerable, predominantly minority urban communities
Correlates of Post-traumatic Stress Disorder in Stroke Survivors
Background
Post-traumatic stress disorder (PTSD) can occur after life-threatening events, including illness, but correlates of PTSD after stroke or transient ischemic attack (TIA) have not been well described.
Methods
We measured the prevalence of stroke-induced PTSD with the PTSD Checklist Specific for stroke (PCL-S) in adults who had a stroke or TIA within 5 years. A PCL-S score of 50 or more indicated likely PTSD. We tested for potential predictors of stroke-associated PTSD, including demographics, stroke history, disability, medical comorbidities, depression, and emotional support and then examined the association between poststroke PTSD and measures of physical and mental health.
Results
Of 535 participants, 95 (18%) had a PCL-S score of 50 or more; the mean score was 35.4 ± 13.7 (range 17-80 of 85). In logistic regression analysis, low income (odds ratio [OR] 1.98, 95% confidence interval [CI] 1.01-3.61), recurrent stroke or TIA (OR 1.86, 1.10-3.16), more disability (OR 1.79, 1.43-2.23), and increased comorbidities (OR 1.90, 1.05-3.45) were independently associated with PTSD. Older age (OR .93, .90-.95), marriage or partnership (OR .52, .28-.98), and having emotional support (OR .25, .11-.54) were protective against developing PTSD. Participants with likely PTSD had worse physical and mental health.
Conclusions
In this racially and ethnically diverse cohort of stroke and TIA survivors, stroke-induced PTSD was associated with younger age, recurrent strokes, greater disability, and comorbidities. PTSD was associated with a substantially increased physical, mental, and quality of life burden in this already vulnerable population. Having social support was protective, suggesting a potential target for intervention
