Abstract: usitis and chronic cough in children Original Research (2349) Total Article Views Authors: Wilson NW, Hogan MB, Harper CB, Peele K, Budhecha S, Loffredo V, Wong V Published Date July 2012 Volume 2012:5 Pages 27 - 32 DOI: http://dx.doi.org/10.2147/JAA.S31874 Received: 17 March 2012 Accepted: 18 April 2012 Published: 30 July 2012 Nevin W Wilson, Mary Beth Hogan, Charles Bruce Harper, Kathy Peele, Sonia Budhecha, Vincent Loffredo, Vanessa Wong University of Nevada School of Medicine, Department of Pediatrics, Section of Allergy, Immunology and Pulmonology, Reno, NV, USA Background: Chronic cough in children is a common problem, and sinusitis is a common etiology. The diagnosis of sinusitis is often clinical, but confirmation is thought to require a CT scan due to the difficulty of interpreting a Water’s view sinus X-ray. Objectives: The purposes of the study were (1) to examine the frequency of an abnormal sinus X-ray in children with a chronic cough of more than 4 weeks duration; (2) to compare the interpretation of the sinus film between allergy/pulmonary clinicians and radiologists; and (3) to correlate symptoms with X-ray results. Methods: A chart review of 2- to 18-year-old patients with coughing exceeding 4 weeks was performed. Data was collected for patients who had received a Water’s view sinus film as part of their evaluation. Exam, X-ray results, and clinical outcomes were categorized and statistical analyses performed. Results: A total of 86 patients were included. Clinicians found that 65% of the children had positive Water’s view films, compared with the radiologist’s reading of 62% (non significant). Significant associations between post-tussive emesis (P = 0.01) and purulence (P = 0.03) were noted with a positive film. Positive sinus X-ray was highly associated with all findings except wheeze when present together (P < 0.001). Conclusions: Sinus abnormalities on X-ray are associated with prolonged cough in 65% of children. The Water’s view sinus film is a clinically useful screening tool for clinicians in the workup of chronic cough. Certain physical findings and clinical complaints, when present concurrently, correlate with the X-ray results.

Can Human Visual Surveillance be Improved with Intent Recognition?
Alireza Tavakkoli,Donald Loffredo
Journal of Systemics, Cybernetics and Informatics , 2013,
Abstract: In video surveillance applications, trained operators watch a number of screens simultaneously to detect potential security threats. Looking for such events in real time, in multiple videos simultaneously, is cognitively challenging for human operators. This study suggests that there is a significant need to use an automated video analysis system to aid human perception of security events in video surveillance applications. In this paper the performance of humans in observing a simulated environment is studied and quantified. Furthermore, this paper proposes an automated mechanism to detect events before they occur by means of an automated intent recognition system. Upon the detection of a potential event the proposed mechanism communicates the location of such potential threat to the human operator to redirect attention to the areas of interest within the video. Studying the improvements achieved by applying the intent recognition into the simulated video surveillance application in a two phase trial supports the need for an automated event detection approach in improving human video surveillance performance. Moreover, this paper presents a comparison of the performance in video surveillance with and without the aid of the intent recognition mechanism.
MicroRNA-9 as Potential Biomarker for Breast Cancer Local Recurrence and Tumor Estrogen Receptor Status
Xin Zhou, Catalin Marian, Kepher H. Makambi, Ourania Kosti, Bhaskar V. S. Kallakury, Christopher A. Loffredo, Yun-Ling Zheng
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0039011
Abstract: MicroRNAs (miRs) are small, non-protein coding transcripts involved in many cellular functions. Many miRs have emerged as important cancer biomarkers. In the present study, we investigated whether miR levels in breast tumors are predictive of breast cancer local recurrence (LR). Sixty-eight women who were diagnosed with breast cancer at the Lombardi Comprehensive Cancer Center were included in this study. Breast cancer patients with LR and those without LR were matched on year of surgery, age at diagnosis, and type of surgery. Candidate miRs were identified by screening the expression levels of 754 human miRs using miR arrays in 16 breast tumor samples from 8 cases with LR and 8 cases without LR. Eight candidate miRs that showed significant differences between tumors with and without LR were further verified in 52 tumor samples using real-time PCR. Higher expression of miR-9 was significantly associated with breast cancer LR in all cases as well as the subset of estrogen receptor (ER) positive cases (p = 0.02). The AUCs (Area Under Curve) of receiver operating characteristic (ROC) curves of miR-9 for all tumors and ER positive tumors are 0.68 (p = 0.02) and 0.69 (p = 0.02), respectively. In ER positive cases, Kaplan-Meier analysis showed that patients with lower miR-9 levels had significantly better 10-year LR-free survival (67.9% vs 30.8%, p = 0.02). Expression levels of miR-9 and another miR candidate, miR-375, were also strongly associated with ER status (p<0.001 for both). The potential of miR-9 as a biomarker for LR warrants further investigation with larger sample size.

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.48A2005
Abstract:

Indoor radon concentration measurements were performed in dwellings of Ischia island (South Italy) using commercial E-Perm devices in LST configuration. The average concentrations in the dwellings were found to vary from 125 to 865 Bq/m3 with an average of 354 ± 176 Bq/m3. This value is higher than Italian National average that is 75 Bq/m3 and Campanian average that is 95 Bq/m3. Correlation between indoor radon concentration measurements and floor level of monitored room was also studied.

Abstract: fatal injuries in children caused by motor vehicle accidents represent a common situation in many countries worldwide. the present study addresses the mortality rate in children as vehicle passengers in brazil, from 1997 to 2005. to evaluate mortality rates, the number of deaths was collected from the national mortality information system (sim) and the population size was obtained using the brazilian bureau census (ibge) data available at datasus. mortality rates were estimated in three-year periods and analyzed according to age groups (younger than 1 year old, 1-4 years old, 5-9 years old) and geographical regions using a 95% confidence interval. overall results showed mortality rates of 5.68, 7.32 and 6.78 (per 1,000,000) for the 1997-1999, 2000-2002 and 2003-2005 periods, respectively for the whole country. children younger than 1 year old had a mortality rate of 10.18 (per 1,000,000), which was higher than for the other age groups. for the period analyzed, the highest rates were observed for the mid-west and south regions of brazil, with rates of 13.88 and 11.47 (per 1,000,000), respectively. these results show the risk of fatal injury in children caused by motor vehicle accidents and may contribute to the establishment of educational campaigns aiming injury prevention in children as vehicle passengers.
Age-Related Grade Inflation Expectancies in a University Environment
Donald A. Loffredo,Rick Harrington
Education Research International , 2012, DOI: 10.1155/2012/789470
Abstract: Grade inflation is a recognized problem in higher education in the United States. Age, gender, and ethnic differences in discrepancies between student reports of their expected grade in each course and their expectations for general university grading practices were explored in a survey of 166 (mostly female) participants at a small upper-division university. Results revealed that while a small minority of students agreed that grading systems in college should only include A or B grades, a large majority of students expected A or B grades. Thus, student discrepancies between their expectations for grading systems and their expected class grades were in line with expectations that they should receive inflated grades. Results also revealed statistically significant age differences in grade expectation with students older than the age of 55 expecting lower grades relative to their younger counterparts.

Introduction and Review of the Relevant Literature Grade inflation, the process of instructors assigning higher grades than is warranted, has been a perennial concern in academia. Particularly in the 1990s, faculty and academic administrators have made their voices heard regarding the issue to such an extent that even students are now beginning to voice concerns [1]. Due to these concerns, even some employers are now skeptical and wary of making employment decisions based solely on university grade point averages [2, 3]. Grade inflation has been reported as an acknowledged problem in higher education in the United States since the late 1960s [4–7]. However, not all research has reported grade inflation or a tendency toward it. Kohn [8] reviewed transcripts from 3,000 institutions of higher education and concluded that grades actually declined between 1975 and 1995. The majority of grade inflation studies, though, continue to report its existence. Landrum [9] conducted a study on student expectation of grades in which 278 students in five different courses were asked about their own academic performance in class using both grade categories (A, B, C, D, and F) and descriptive criteria for grades (such as A = distinguished, B = superior, C = average, D = below average, and F = failure) taken directly from the official Boise State University catalog. Descriptive criteria for grades in the Landrum study are found in the options following this sample item stem: my work in this class is best described as (a) a distinguished work, (b) a superior work, (c) an average work, (d) a below average work, and (e) a failure. Note that in this sample survey item the actual
