Numerous professional societies, clinical practices, and hospitals provide Internet-based patient education materials (PEMs) to the general public, but not all of this information is written at a reading level appropriate for the average patient. The National Institutes of Health and the US Department of Health and Human Services recommend that PEMs be written at or below the sixth-grade level. Our purpose was to assess the readability of endoscopic sinus surgery (ESS)-related PEMs available on the Internet and compare readability levels of PEMs provided by three sources: professional societies, clinical practices, and hospitals. A descriptive and correlational design was used for this study. The readability of 31 ESS-related PEMs was assessed with four different readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. The majority of PEMs (96.8%) were written above the recommended sixth-grade reading level, based on FKGL (P < .001). Only one article (3.2%) had an FKGL at or below the sixth-grade level. The mean readability values were: FRES 47.1 ± 13.4, FKGL 10.7 ± 2.4, SMOG 13.7 ± 1.6, and Gunning FOG 12.4 ± 2.7. Current Internet-based PEMs related to ESS, regardless of source type, were written well above the recommended sixth-grade level. Materials from the hospitals/university-affiliated websites had lower readability scores, but were still above recommended levels. Web-based PEMs pertaining to ESS should be written with the average patient in mind. Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.

Estimating tree grades for Southern Appalachian natural forest stands

Treesearch

1998-01-01

Log prices can vary significantly by grade: grade 1 logs are often several times the price per unit of grade 3 logs. Because tree grading rules derive from log grading rules, a model that predicts tree grades based on tree and stand-level variables might be useful for predicting stand values. The model could then assist in the modeling of timber supply and in economic...

The primary objective is to identify effective land-based therapeutic exercise interventions and provide evidence-based recommendations for managing hip osteoarthritis. A secondary objective is to develop an Ottawa Panel evidence-based clinical practice guideline for hip osteoarthritis. The search strategy and modified selection criteria from a Cochrane review were used. Studies included hip osteoarthritis patients in comparative controlled trials with therapeutic exercise interventions. An Expert Panel arrived at a Delphi survey consensus to endorse the recommendations. The Ottawa Panel hierarchical alphabetical grading system (A, B, C+, C, D, D+, or D-) considered the study design (level I: randomized controlled trial and level II: controlled clinical trial), statistical significance (p < 0.5), and clinical importance (⩾15% improvement). Four high-quality studies were included, which demonstrated that variations of strength training, stretching, and flexibility exercises are generally effective for improving the management of hip osteoarthritis. Strength training exercises displayed the greatest improvements for pain (Grade A), disability (Grades A and C+), physical function (Grade A), stiffness (Grade A), and range of motion (Grade A) within a short time period (8-24 weeks). Stretching also greatly improved physical function (Grade A), and flexibility exercises improved pain (Grade A), range of motion (Grade A), physical function (Grade A), and stiffness (Grade C+). The Ottawa Panel recommends land-based therapeutic exercise, notably strength training, for management of hip osteoarthritis in reducing pain, stiffness and self-reported disability, and improving physical function and range of motion. © The Author(s) 2015.

2015-03-01

The US Department of Health and Human Services (USDHHS) recommends that Internet-based patient education materials (IPEMs) be written below the sixth-grade reading level to target the average American adult. This study was designed to determine the readability of IPEMs regarding mammography for breast cancer screening. Three-hundred mammography-related Web sites were reviewed for IPEMs. Forty-two IPEMs that met the Health on the Net Foundation Code of Conduct were assessed for readability level with four readability indices that use existing algorithms based on word and sentence length to quantitatively analyze Internet sources for language intricacy including the following: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG; GFOG). Results were compared to national recommendations, and intergroup analysis was performed. No IPEMs (0%) regarding mammography were written at or below the sixth-grade reading level, based on FKGL. The mean readability scores were as follows: FRES, 49.04 ± 10.62; FKGL, 10.71 ± 2.01; SMOG, 13.33 ± 1.67; and Gunning FOG, 14.32 ± 2.18. These scores indicate that the readability of mammography IPEMs is written at a "difficult" level, significantly above the recommended sixth-grade reading level (P < .05) determined by the USDHHS. IPEMs related to mammography are written well above the recommended sixth-grade level and likely reflect other IPEMs in diagnostic radiology. Copyright © 2015 AUR. Published by Elsevier Inc.

An Investigation of the Generalizability of Medical School Grades.

PubMed

Kreiter, Clarence D; Ferguson, Kristi J

2016-01-01

Construct/Background: Medical school grades are currently unstandardized, and their level of reliability is unknown. This means their usefulness for reporting on student achievement is also not well documented. This study investigates grade reliability within 1 medical school. Generalizability analyses are conducted on grades awarded. Grades from didactic and clerkship-based courses were treated as 2 levels of a fixed facet within a univariate mixed model. Grades from within the 2 levels (didactic and clerkship) were also entered in a multivariate generalizability study. Grades from didactic courses were shown to produce a highly reliable mean score (G = .79) when averaged over as few as 5 courses. Although the universe score correlation between didactic and clerkship courses was high (r = .80), the clerkship courses required almost twice as many grades to reach a comparable level of reliability. When grades were converted to a Pass/Fail metric, almost all information contained in the grades was lost. Although it has been suggested that the imprecision of medical school grades precludes their use as a reliable indicator of student achievement, these results suggest otherwise. While it is true that a Pass/Fail system of grading provides very little information about a student's level of performance, a multi-tiered grading system was shown to be a highly reliable indicator of student achievement within the medical school. Although grades awarded during the first 2 didactic years appear to be more reliable than clerkship grades, both yield useful information about student performance within the medical college.

This study focuses on designing learning continuum for developing a curriculum. The objective of this study is to get the opinion of junior and senior high school teachers about Learning Continuum based on Student's Level of Competence and Specific Pedagogical Learning Material on Aspect of Genetics Aspects. This research is a survey research involving 281 teachers from junior and senior high school teachers as respondents taken from five districts and city in Yogyakarta Special Region. The results of this study show that most of the junior high school teachers argue that sub aspects individual reproduction should be taught to students of grade VII and IX, virus reproduction at the grade X, and cell reproduction to mutation at the grade IX with level of competence to understand (C2) while most of the senior high school teachers argue that sub aspects individual, cell, and virus reproduction must be taught to students of grade X and division mechanism to mutation at the grade XII with level of competence to understand (C2), apply (C3), and analyze (C4). Based on the opinion of teachers, sub concepts in genetics can be taught from junior high school with different in the scope of materials but learning continuum that has been developed is not relevant with the students cognitive development and their grades.

A risk-based classification scheme for genetically modified foods. II: Graded testing.

PubMed

Chao, Eunice; Krewski, Daniel

2008-12-01

This paper presents a graded approach to the testing of crop-derived genetically modified (GM) foods based on concern levels in a proposed risk-based classification scheme (RBCS) and currently available testing methods. A graded approach offers the potential for more efficient use of testing resources by focusing less on lower concern GM foods, and more on higher concern foods. In this proposed approach to graded testing, products that are classified as Level I would have met baseline testing requirements that are comparable to what is widely applied to premarket assessment of GM foods at present. In most cases, Level I products would require no further testing, or very limited confirmatory analyses. For products classified as Level II or higher, additional testing would be required, depending on the type of the substance, prior dietary history, estimated exposure level, prior knowledge of toxicity of the substance, and the nature of the concern related to unintended changes in the modified food. Level III testing applies only to the assessment of toxic and antinutritional effects from intended changes and is tailored to the nature of the substance in question. Since appropriate test methods are not currently available for all effects of concern, future research to strengthen the testing of GM foods is discussed.

2010-03-01

The ability to critically appraise the calibre of studies in medical literature is increasingly important for medical professionals. This prospective controlled study evaluated the impact of a 6-h Evidence Based Medicine (EBM) Workshop on the critical appraisal skills of medical trainees. Individuals attended three 2-h workshops over a 3-week period, incorporating didactic lectures in statistics, clinical trial design, appraising research papers and practical examples. Appraisal skills were assessed pre- and post-training based on grading the quality of randomised control studies (level 1 evidence), cohort studies (level 2 evidence) and case-control studies (level 3 evidence) [From Oxford Centre for Evidence Based Medicine Levels of Evidence (2001), http://www.cebm.net/critical_appraisal.asp ]. Overall grading improved from 39% (pre-course) to 74% (post-course), P = 0.002, with grading of levels 1, 2 and 3 studies improving from 42 to 75%, 53 to 61% and 21 to 84%, respectively. We conclude that a 6-h formal EBM workshop is effective in enhancing the critical appraisal skills of medical trainees.

Although national and state estimates of child obesity are available, data at these levels are insufficient to monitor effects of local obesity prevention initiatives. The purpose of this study was to examine regional changes in the prevalence of obesity due to state-wide policies and programs among children in grades 4, 8, and 11 in Texas Health Service Regions (HSR) between 2000–2002 and 2004–2005, and nine selected counties in 2004–2005. A cross-sectional, probability-based sample of 23,190 Texas students in grades 4, 8, and 11 were weighed and measured to obtain body mass index (BMI). Obesity was greater than 95th percentile for BMI by age/sex using CDC growth charts. Child obesity prevalence significantly decreased between 2000–2002 and 2004–2005 for 4th grade students in the El Paso HSR (−7.0%, p=0.005). A leveling off in the prevalence of obesity was noted for all other regions for grades 4, 8 and 11. County-level data supported the statistically significant decreases noted in the El Paso region. The reduction of child obesity levels observed in the El Paso area is one of the few examples of effective programs and policies based on a population-wide survey: in this region, a local foundation funded extensive regional implementation of community programs for obesity prevention, including an evidence-based elementary school-based health promotion program, adult nutrition and physical activity programs, and a radio and television advertising campaign. Results emphasize the need for sustained school, community and policy efforts, and that these efforts can result in decreases in child obesity at the population level. PMID:19798066

Readmission after treatment of Grade 3 and 4 renal injuries at a Level I trauma center: Statewide assessment using the Comprehensive Hospital Abstract Reporting System.

PubMed

Winters, Brian; Wessells, Hunter; Voelzke, Bryan B

2016-03-01

One criticism of the existing renal trauma research is the limited outpatient follow-up after index hospitalization. We assessed readmission rates following treatment for American Association for the Surgery of Trauma (AAST) Grade 3 and 4 renal injury using the Comprehensive Hospital Abstract Reporting System (CHARS). We evaluated all patients with AAST Grade 3 and 4 renal injuries admitted to Harborview Medical Center (HMC) between 1998 and 2010, the only Level 1 trauma center in Washington state. Grade 4 renal injuries were stratified by collecting system laceration (CSL) or segmental vascular injury. Data were abstracted from the CHARS database for readmissions to any Washington state hospital within 6 months of renal injury. Clinical variables, diagnoses, and procedures were queried based on DRG International Classification of Diseases-9th Rev. codes. A total of 477 Grade 3 and 159 Grade 4 renal injuries were initially treated at HMC. On admission, 111 patients required intervention: 75 (16%) of 477 Grade 3 and 36 (23%) of 159 Grade 4 injuries. Within 6 months of index hospitalization, 86 (18%) of 477 Grade 3 and 38 (24%) of 159 Grade 4 patients were readmitted to any Washington state hospital. Eighty percent of Grade 3 injuries and 66% of Grade 4 injuries returned to HMC compared with secondary hospitals (p = 0.08). At readmission, 19 (22%) of 86 Grade 3 and 16 (42%) of 38 Grade 4 injuries had a urologic diagnosis. Subsequent procedural intervention was required on readmission in 6 (7%) of 86 Grade 3 and 5 (13%) of 38 Grade 4 renal injuries (all CSL injuries). A subset of patients treated for Grade 3 and 4 renal trauma will be readmitted for further management. While urologic diagnoses and additional procedures may be low overall, readmission to outside hospitals may preclude accurate determination of renal trauma outcomes. Based on these data, patients with Grade 4 CSL injuries seem to be at the highest risk for readmission and to require a subsequent urologic procedure. Prognostic/epidemiologic study, level III.

Diagnostic accuracy of pre-treatment biopsy for grading cutaneous mast cell tumours in dogs.

PubMed

Shaw, T; Kudnig, S T; Firestone, S M

2018-06-01

Mast cell tumours (MCTs) are common tumours of the canine skin, and are estimated to represent up to 20% of all skin tumours in dogs. Tumour grade has a major impact on the incidence of local recurrence and metastatic potential. In addition to helping the clinician with surgical planning, knowledge of the tumour grade also assists in proper prognostication and client education. For pre-treatment biopsies to be useful, there must exist a high level of correlation between the histopathological grade obtained from the pre-treatment biopsy and the actual histopathological grade from the excisional biopsy. The aim of this study was to determine concordance of tumour grade between various biopsy techniques (wedge, punch, needle core) and the "gold standard" excisional biopsy method. We found an overall concordance rate of 96% based on the Patnaik grading system, and an overall concordance rate of 92% based on the Kiupel grading system. The accuracy of the various biopsy techniques (wedge, punch and needle core) when compared with excisional biopsy was 92%, 100% and 100%, respectively, based on the Patnaik grading system, and 90%, 95% and 100%, respectively, based on the Kiupel grading system. Of the cases with discordant results, the pre-treatment biopsies tended to underestimate the grade of the tumour. Based on these results, we conclude that pre-treatment biopsies are sufficiently accurate for differentiating low-grade from high-grade MCTs, regardless of biopsy technique or tumour location. © 2017 John Wiley & Sons Ltd.

Impact of a universal school-based violence prevention program on violent delinquency: distinctive benefits for youth with maltreatment histories.

Crooks, Claire V; Scott, Katreena; Ellis, Wendy; Wolfe, David A

2011-06-01

Child maltreatment constitutes a strong risk factor for violent delinquency in adolescence, with cumulative experiences of maltreatment creating increasingly greater risk. Our previous work demonstrated that a universal school-based violence prevention program could provide a protective impact for youth at risk for violent delinquency due to child maltreatment history. In this study we conducted a follow-up to determine if participation in a school-based violence prevention program in grade 9 continued to provide a buffering effect on engaging in acts of violent delinquency for maltreated youth, 2 years post-intervention. Secondary analyses were conducted using data from a cluster randomized controlled trial of a comprehensive school-based violence prevention program. Students (N=1,722; 52.8% female) from 20 schools participated in 21 75-min lessons in grade 9 health classes. Individual data (i.e., gender, child maltreatment experiences, and violent delinquency in grade 9) and school-level data (i.e., student perception of safety averaged across students in each school) were entered in a multilevel model to predict violent delinquency at the end of grade 11. Individual- and school-level factors predicting violent delinquency in grade 11 replicated previous findings from grade 9: being male, experiencing child maltreatment, being violent in grade 9, and attending a school with a lower perceived sense of safety among the entire student body increased violent delinquency. The cross-level interaction of individual maltreatment history and school-level intervention was also replicated: in non-intervention schools, youth with more maltreatment in their background were increasingly likely to engage in violent delinquency. The strength of this relationship was significantly attenuated in intervention schools. Follow-up findings are consistent with the buffering effect of the prevention program previously found post-intervention for the subsample of youth with maltreatment histories. A relative inexpensive school-based violence prevention program that has been shown to reduce dating violence among the whole student body also creates a protective effect for maltreated youth with respect to lowering their likelihood of engaging in violent delinquency.

2012-09-01

Various professional societies, clinical practices, hospitals, and health care-related Web sites provide Internet-based patient education material (IPEMs) to the general public. However, this information may be written above the 6th-grade reading level recommended by the US Department of Health and Human Services. The purpose of this study is to assess the readability of facial fracture (FF)-related IPEMs and compare readability levels of IPEMs provided by four sources: professional societies, clinical practices, hospitals, and miscellaneous sources. Analysis of IPEMs on FFs available on Google.com. The readability of 41 FF-related IPEMs was assessed with four readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. Only 4.9% of IPEMs were written at or below the 6th-grade reading level, based on FKGL. The mean readability scores were: FRES 54.10, FKGL 9.89, SMOG 12.73, and Gunning FOG 12.98, translating into FF-related IPEMs being written at a "difficult" writing level, which is above the level of reading understanding of the average American adult. IPEMs related to FFs are written above the recommended 6th-grade reading level. Consequently, this information would be difficult to understand by the average US patient.

A Comparison of Children's Physical Activity Levels in Physical Education, Recess, and Exergaming.

PubMed

Gao, Zan; Chen, Senlin; Stodden, David F

2015-03-01

To compare young children's different intensity physical activity (PA) levels in physical education, recess and exergaming programs. Participants were 140 first and second grade children (73 girls; Meanage= 7.88 years). Beyond the daily 20-minute recess, participants attended 75-minute weekly physical education classes and another 75-minute weekly exergaming classes. Children's PA levels were assessed by ActiGraph GTX3 accelerometers for 3 sessions in the 3 programs. The outcome variables were percentages of time spent in sedentary, light PA and moderate-to-vigorous PA (MVPA). There were significant main effects for program and grade, and an interaction effect for program by grade. Specifically, children's MVPA in exergaming and recess was higher than in physical education. The 2nd-grade children demonstrated lower sedentary behavior and MVPA than the first-grade children during recess; less light PA in both recess and exergaming than first-grade children; and less sedentary behavior but higher MVPA in exergaming than first-grade children. Young children generated higher PA levels in recess and exergaming as compared with physical education. Hence, other school-based PA programs may serve as essential components of a comprehensive school PA program. Implications are provided for educators and health professionals.

Predictors of gender achievement in physical science at the secondary level

NASA Astrophysics Data System (ADS)

Kozlenko, Brittany Hunter

This study used the 2009 National Assessment of Educational Progress (NAEP) science restricted data-set for twelfth graders. The NAEP data used in this research study is derived from a sample group of 11,100 twelfth grade students that represented a national population of over 3,000,000 twelfth grade students enrolled in science in the United States in 2009. The researcher chose the NAEP data set because it provided a national sample using uniform questions. This study investigated how the factors of socioeconomic status (SES), parental education level, mode of instruction, and affective disposition affect twelfth grade students' physical science achievement levels in school for the sample population and subgroups for gender. The factors mode of instruction and affective disposition were built through factor analysis based on available questions from the student surveys. All four factors were found to be significant predictors of physical science achievement for the sample population. NAEP exams are administered to a national sample that represents the population of American students enrolled in public and private schools. This was a non-experimental study that adds to the literature on factors that impact physical science for both genders. A gender gap is essentially nonexistent at the fourth grade level but appears at the eighth grade level in science based on information from NAEP (NCES, 1997). The results of the study can be used to make recommendation for policy change to diminish this gender gap in the future. Educators need to be using research to make instructional decisions; research-based instruction helps all students.

The effectiveness of print-based health promotion materials is dependent on their readability. This study aimed to assess the characteristics of print-based oral health information literature publically available in Tasmania, Australia. Oral health education brochures were collected from 11 dental clinics across Tasmania and assessed for structure and format, content and readability. Reading level was calculated using three widely-used measures: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease, and Simple Measure of Gobbledygook (SMOG) reading grade level. The FKGL of the 67 brochures sampled ranged from grade 3 to 13. The grade level for government health department brochures (n = 14) ranged from grade 4 to 11 (5.6 ± 1.8). Reading levels for materials produced by commercial sources (n = 22) ranged from 3 to 13 (8.3 ± 2.1), those from professional associations (n = 22) ranged from grade 7 to 11 (8.9 ± 0.9) and brochures produced by other sources (n = 9) ranged from 5 to 10 (7.6 ± 1.5). The SMOG test was positively correlated with the FKGL (rs = 0.92, p < 0.001) though consistently rated materials 2-3 grades higher. The reading level required to comprehend brochures published by government sources were, on average, lower than those from commercial, professional and other sources. Government materials were also more likely to contain fewer words and professional jargon terms than brochures from the other sources. A range of oral health information brochures were publically available for patients in both public and private dental clinics. However, their readability characteristics differed. Many brochures required a reading skill level higher than that suited to a large proportion of the Tasmanian population. Readability and other characteristics of oral health education materials should be assessed to ensure their suitability for use with patients, especially those suspected of having low literacy skills.

Anorectal disorders such as dyssynergic defecation, fecal incontinence, levator ani syndrome and solitary rectal ulcer syndrome are common, and affect both the adult and pediatric populations. Although they are treated with several treatment approaches, over the last two decades, biofeedback therapy using visual and verbal feedback techniques has emerged as an useful option. Because it is safe, it is commonly recommended. However, the clinical efficacy of biofeedback therapy in adults and children is not clearly known, and there is a lack of critical appraisal of the techniques used and the outcomes of biofeedback therapy for these disorders. The American Neurogastroenterology and Motility Society and the European Society of Neurogastroenterology and Motility convened a task force to examine the indications, study performance characteristics, methodologies used and the efficacy of biofeedback therapy, and to provide evidence-based recommendations. Based on the strength of evidence, biofeedback therapy is recommended for the short term and long term treatment of constipation with dyssynergic defecation (Level I, Grade A), and for the treatment of fecal incontinence (Level II, Grade B). Biofeedback therapy may be useful in the short-term treatment of Levator Ani Syndrome with dyssynergic defecation (Level II, Grade B), and solitary rectal ulcer syndrome with dyssynergic defecation (Level III, Grade C), but the evidence is fair. Evidence does not support the use of biofeedback for the treatment of childhood constipation (Level 1, Grade D). PMID:25828100

Development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and the American College of Endocrinology (ACE) Board of Trustees and adheres to published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Recommendations are based on diligent review of clinical evidence with transparent incorporation of subjective factors. There are 9 broad clinical questions with 123 recommendation numbers that include 160 specific statements (85 [53.1%] strong [Grade A], 48 [30.0%] intermediate [Grade B], and 11 [6.9%] weak [Grade C], with 16 [10.0%] based on expert opinion [Grade D]) that build a comprehensive medical care plan for obesity. There were 133 (83.1%) statements based on strong (best evidence level [BEL] 1 = 79 [49.4%]) or intermediate (BEL 2 = 54 [33.7%]) levels of scientific substantiation. There were 34 (23.6%) evidence-based recommendation grades (Grades A-C = 144) that were adjusted based on subjective factors. Among the 1,788 reference citations used in this CPG, 524 (29.3%) were based on strong (evidence level [EL] 1), 605 (33.8%) were based on intermediate (EL 2), and 308 (17.2%) were based on weak (EL 3) scientific studies, with 351 (19.6%) based on reviews and opinions (EL 4). The final recommendations recognize that obesity is a complex, adiposity-based chronic disease, where management targets both weight-related complications and adiposity to improve overall health and quality of life. The detailed evidence-based recommendations allow for nuanced clinical decision-making that addresses real-world medical care of patients with obesity, including screening, diagnosis, evaluation, selection of therapy, treatment goals, and individualization of care. The goal is to facilitate high-quality care of patients with obesity and provide a rational, scientific approach to management that optimizes health outcomes and safety.

High-grade primary brain tumors possessed poor outcome due to invasiveness. Extracellular matrix metalloproteinase inducer (EMMPRIN) stimulates peri-tumoral fibroblasts to secrete matrix metalloproteinase and promote invasiveness. This study hypothesized that high-grade brain tumors overexpress EMMPRIN. Analyzing the public delinked database from the Gene Expression Omnibus profile, the results showed that the EMMPRIN mRNA level was higher in WHO grade IV (n = 81) than in grade III (n = 19, p < 0.0005) astrocytomas and non-tumor brain tissue controls (n = 23, p < 0.00001). The results of tissue microarray-based immunohistochemical (IHC) staining revealed that EMMPRIN levels positively correlated with WHO grades for astrocytomas (p = 0.008) and meningiomas (p = 0.048). EMMPRIN mRNA levels in conventional glioma cell lines (n = 36) was not less than those in glioma primary culture cells (n = 27) and glioblastoma stem-like cells (n = 12). The GBM8401, U87MG, and LN229 human glioma cell lines also overexpressed EMMPRIN. Hematoxylin and eosin, IHC, and immunofluorescence staining of xenografts confirmed that high-grade brain tumors overexpressed EMMPRIN. Lastly, Kaplan-Meier analysis revealed poorer survival in WHO grade IV (n = 56) than in grade III astrocytomas (n = 21, by log-rank test; p = 0.0001, 95 % CI: 1.842-3.053). However, in high-grade astrocytomas, there was no difference in survival between high and low EMMPRIN mRNA levels. Thus, this study identified that high-grade brain tumors overexpress EMMPRIN, which positively correlates with WHO grades in human astrocytomas and meningiomas, and suggests that EMMPRIN may be a therapeutic target of brain tumor.

The scope of learning continuum at the conceptual knowledge is formulated based on the student's level of competence and specific pedagogical learning material. The purpose of this study is to develop a learning continuum of specific pedagogical material aspects of physiology targeted for students in primary and secondary education. This research was conducted in Province of Yogyakarta Special Region from October 2016 to January 2017. The method used in this study was survey method. The data were collected using questionnaire that had been validated from the aspects of construct validity and experts judgements. Respondents in this study consist of 281 Science/Biology teachers at Public Junior and Senior High Schools in the Province of Yogyakarta Special Region which spread in Yogyakarta city and 4 regencies namely Sleman, Bantul, Kulonprogo, and Gunungkidul. The data were taken using a census. Data were analyzed using a descriptive analysis technique. The results show the learning continuum of physiology based on teachers's opinion from grade VII, VIII, and IX are taught in grade VII, VIII, IX and X on level of C2 (understanding) and the learning continuum of physiology based on teachers's opinion from grade X, XI and XII are taught in grade X and XI on level of C2 (understanding), C3 (applying), and C4 (analyzing) based on teachers's opinions. The conclusion is that many teachers refer to the existing curriculum rather than their own original idea for developing learning continuum.

2015-08-01

The main objective of the current investigation was to assess the readability of Internet-based patient education materials related to the field of anesthesiology. We hypothesized that the majority of patient education materials would not be written according to current recommended readability grade level. Online patient education materials describing procedures, risks, and management of anesthesia-related topics were identified using the search engine Google (available at www.google.com) using the terms anesthesia, anesthesiology, anesthesia risks, and anesthesia care. Cross-sectional evaluation. None. Assessments of content readability were performed using validated instruments (Flesch-Kincaid Grade Formulae, the Gunning Frequency of Gobbledygook, the New Dale-Chall Test, the Fry graph, and the Flesch Reading Ease score). Ninety-six Web sites containing Internet patient education materials (IPEMs) were evaluated. The median (interquartile range) readability grade level for all evaluated IPEMs was 13.5 (12.0-14.6). All the evaluated documents were classified at a greater readability level than the current recommended readability grade, P < .001. Readability grades were not significantly different among different IPEM sources. Assessment by the Flesch Reading Ease test classified all but 4 IPEMs as at least fairly difficult to read. Internet-based patient education materials related to the field of anesthesiology are currently written far above the recommended readability grade level. High complexity of written education materials likely limits access of information to millions of American patients. Redesign of online content of Web sites that provide patient education material regarding anesthesia could be an important step in improving access to information for patients with poor health literacy.

2015-08-01

To identify rehabilitation interventions that can be integrated into ward-based nursing for patients with hemispatial neglect following stroke in the right brain hemisphere. A systematic review of interdisciplinary literature. A preliminary literature search without time limits was conducted in the Cochrane Controlled Trials Register. We then searched the PubMed, CINAHL and PsychINFO databases for relevant articles published between January 2006 and June 2014. Selected journals were searched manually. Additional resources were explored by scrutinizing reference lists and tracking citations of the selected articles. Titles and abstracts were matched with the inclusion criteria. Articles were read in their entirety if the abstracts adhered to inclusion criteria or if there was any uncertainty. Two reviewers evaluated the risk of methodological bias independently by using quantitative appraisal forms from the Johanna Briggs Institute (JBI). Any disagreements were resolved by consensus. Authors of nine studies were contacted to acquire additional information. The JBI Reviewers' Manual was used to guide the overall procedure of the review. We used the PRISMA statement to ensure precise reporting of the results. The selected studies were graded according to the strength of their evidence (Levels 1-5); the proposed interventions were given recommendation grades (Grades A-D). Using 41 original studies, 11 interventions were identified. These comprise: (1) contralesional neck vibration (Grade C); (2) emotionally salient stimuli and reward (Grade D); (3) family participation and intensity of training (Grade C); (4) limb activation training (Grade C); (5) mental imagery training, (Grade D); (6) mirror therapy (Grade C); (7) music therapy (Grade D); (8) right half-field eye patching (Grade D); (9) smooth pursuit eye-movement training (Grade B); (10) virtual reality and computer-based training (Grade C); and (11) visual scanning training (Grade D). A total of 11 promising rehabilitation interventions were found. Encouraging results were, in particular, seen with smooth pursuit eye-movement training. It should be noted that the general low level of evidence and the diversity of interventions makes it difficult to endorse specific priorities and combinations for implementation. Instead, interventions should be applied after careful evaluation of each patient's unique capacities and problems. We include suggestions for operationalization into ward-based care in "Discussion" section. We also emphasize the need to integrate evidence-based interventions into nursing care to further stimulate rehabilitation outcomes and future research. Copyright © 2015 Elsevier Ltd.

2016-05-01

To evaluate a center of rotation of angulation (CORA)-based leveling osteotomy for cranial cruciate ligament injury in dogs. Retrospective case series. Dogs (n=70). Medical records (March 2011 to March 2012) of dogs diagnosed with a cranial cruciate ligament (CCL) injury treated with a CORA-based leveling osteotomy and stabilized using a bone plate and headless compression screw were reviewed. Radiographs were reviewed for tibial plateau angle and radiographic healing at final evaluation graded on a 5-point scale. Follow-up for a minimum of 6 months postoperatively was conducted by owner completion of a questionnaire regarding their dog's function after surgery. Based on owner responses, clinical outcomes were established. CORA-based leveling osteotomy was used for 70 stifles with CCL injury. The mean time to final radiographic recheck was 107 days (range, 32-424 days). Radiographic healing scores were 42 dogs (69%) with grade 4, 17 dogs (28%) with grade 3, and 2 dogs (3%) with grade 2. The mean time to follow-up was 11.9 months (range 6-18 months). Fifty-four of the 70 (77%) dogs had full function, 13 (19%) had acceptable function, and 3 (4%) had unacceptable function. Complications occurred in 11 stifles (16%), including 3 incisional, 6 late-onset meniscal tears, and 2 implant related. The described method of a CORA-based leveling osteotomy can be successfully performed for treatment of CCL injury in dogs. At the time of mid-term and long-term owner follow-up, most dogs in this case series had returned to full function. © Copyright 2016 by The American College of Veterinary Surgeons.

One of the goals of the American Academy of Orthopaedic Surgeons (AAOS) is to disseminate patient education materials that suit the readability skills of the patient population. According to standard guidelines from healthcare organizations, the readability of patient education materials should be no higher than the sixth-grade level. We hypothesized the readability level of patient education materials available on the AAOS Web site would be higher than the recommended grade level, regardless when the material was available online. Readability scores of all articles from the AAOS Internet-based patient information Web site, "Your Orthopaedic Connection," were determined using the Flesch-Kincaid grade formula. The mean Flesch-Kincaid grade level of the 426 unique articles was 10.43. Only 10 (2%) of the articles had the recommended readability level of sixth grade or lower. The readability of the articles did not change with time. Our findings suggest the majority of the patient education materials available on the AAOS Web site had readability scores that may be too difficult for comprehension by a substantial portion of the patient population.

Acute malnutrition is linked to child mortality and morbidity. Community-Based Management of Acute Malnutrition (CMAM) programs can be instrumental in large-scale detection and treatment of undernutrition. The World Health Organization (WHO) 2006 weight-for-height/length tables are diagnostic tools available to screen for acute malnutrition. Frontline workers (FWs) in a CMAM program in Dharavi, Mumbai, were using CommCare, a mobile application, for monitoring and case management of children in combination with the paper-based WHO simplified tables. A strategy was undertaken to digitize the WHO tables into the CommCare application. To measure differences in diagnostic accuracy in community-based screening for acute malnutrition, by FWs, using a mobile-based solution. Twenty-seven FWs initially used the paper-based tables and then switched to an updated mobile application that included a nutritional grade calculator. Human error rates specifically associated with grade classification were calculated by comparison of the grade assigned by the FW to the grade each child should have received based on the same WHO tables. Cohen kappa coefficient, sensitivity and specificity rates were also calculated and compared for paper-based grade assignments and calculator grade assignments. Comparing FWs (N = 14) who completed at least 40 screenings without and 40 with the calculator, the error rates were 5.5% and 0.7%, respectively (p < .0001). Interrater reliability (κ) increased to an almost perfect level (>.90), from .79 to .97, after switching to the mobile calculator. Sensitivity and specificity also improved significantly. The mobile calculator significantly reduces an important component of human error in using the WHO tables to assess acute malnutrition at the community level. © The Author(s) 2016.

STS-based education in non-majors college biology

NASA Astrophysics Data System (ADS)

Henderson, Phyllis Lee

The study explored the effect of the science-technology-society (STS) and traditional teaching methods in non-majors biology classes at a community college. It investigated the efficacy of the two methods in developing cognitive abilities at Bloom's first three levels of learning. It compared retention rates in classes taught in the two methods. Changes in student attitude relating to anxiety, fear, and interest in biology were explored. The effect of each method on grade attainment among men and women was investigated. The effect of each method on grade attainment among older and younger students was examined. Results of the study indicated that no significant differences, relating to retention or student attitude, existed in classes taught in the two methods. The study found no significant cognitive gains at Bloom's first three levels in classes taught in the traditional format. In the STS classes no significant gains were uncovered at Bloom's first level of cognition. Statistically significant gains were found in the STS classes at Bloom's second and third levels of cognition. In the classes taught in the traditional format no difference was identified in grade attainment between males and females. In the STS-based classes a small correlational difference between males and females was found with males receiving lower grades than expected. No difference in grade attainment was found between older and younger students taught in the traditional format. In the STS-based classes a small statistically significant difference in grade attainment was uncovered between older and younger students with older students receiving more A's and fewer C's than expected. This study found no difference in the grades of older, female students as compared to all other students in the traditionally taught classes. A weak statistically significant difference was discovered between grade attainment of older, female students and all other students in the STS classes with older, female students earning more A's and fewer C's than expected. It was concluded that among the students examined in this investigation STS teaching methods enhanced cognitive gains at Bloom's second and third levels of cognition. STS also strengthened grade attainment among older students and female students. Recommendations for further study included replication of the study to include a larger sample size, other types of institutions, and other academic disciplines in science. Expansion of the study to Bloom's fourth and fifth levels, use of a standardized testing instruments to determine attitude, analysis using qualitative methods of investigation, and refinement of the study to provide a true experimental design were also suggested.

The 2015 European Thyroid Association Guidelines on Diagnosis and Treatment of Endogenous Subclinical Hyperthyroidism

Biondi, Bernadette; Bartalena, Luigi; Cooper, David S.; Hegedüs, Laszlo; Laurberg, Peter; Kahaly, George J.

2015-01-01

Endogenous subclinical hyperthyroidism (SHyper) is caused by Graves' disease, autonomously functioning thyroid nodules and multinodular goitre. Its diagnosis is based on a persistently subnormal serum thyroid-stimulating hormone (TSH) level with free thyroid hormone levels within their respective reference intervals. In 2014 the European Thyroid Association Executive Committee, given the controversies regarding the treatment of Endo SHyper, formed a task force to develop clinical practice guidelines based on the principles of evidence-based medicine. The task force recognized that recent meta-analyses, including those based on large prospective cohort studies, indicate that SHyper is associated with increased risk of coronary heart disease mortality, incident atrial fibrillation, heart failure, fractures and excess mortality in patients with serum TSH levels <0.1 mIU/l (grade 2 SHyper). Therefore, despite the absence of randomized prospective trials, there is evidence that treatment is indicated in patients older than 65 years with grade 2 SHyper to potentially avoid these serious cardiovascular events, fractures and the risk of progression to overt hyperthyroidism. Treatment could be considered in patients older than 65 years with TSH levels 0.1-0.39 mIU/l (grade 1 SHyper) because of their increased risk of atrial fibrillation, and might also be reasonable in younger (<65 years) symptomatic patients with grade 2 SHyper because of the risk of progression, especially in the presence of symptoms and/or underlying risk factors or co-morbidity. Finally, the task force concluded that there are no data to support treating SHyper in younger asymptomatic patients with grade 1 SHyper. These patients should be followed without treatment due to the low risk of progression to overt hyperthyroidism and the weaker evidence for adverse health outcomes. PMID:26558232

Neutropenia is a major adverse event of docetaxel-based chemotherapy. The present study was undertaken to evaluate the incidence of neutropenia and to develop a nomogram for predicting Grade 4 neutropenia during the first cycle of docetaxel-based chemotherapy in patients with castration-resistant prostate cancer (CRPC). This study included 112 patients with CRPC treated with docetaxel-based systemic chemotherapy. We evaluated the incidence and risk factors for Grade 4 neutropenia in the first cycle of chemotherapy. Sixty-two of 112 patients (55.4%) developed Grade 4 neutropenia in the first cycle of docetaxel-based chemotherapy. There were significant differences in age, baseline white blood cell count, and baseline neutrophil count between patients with non-Grade 4 neutropenia and those with Grade 4 neutropenia in univariate analyses. The serum prostate-specific antigen level, hemoglobin level, creatinine, albumin, Eastern Cooperative Oncology Group performance status, metastatic sites, extent of disease, and history of external beam radiotherapy to the prostate were not significantly different between the 2 groups. Multivariate logistic regression analysis showed that age (odds ratio [OR], 1.08; P = .019) and baseline neutrophil counts (OR, 0.79; P = .045) were significant independent risk factors for severe neutropenia. A nomogram and a calibration plot on the basis of these results were developed from a multivariate logistic regression analysis to predict the probability of Grade 4 neutropenia. Age and baseline neutrophil counts were significant independent risk factors for Grade 4 neutropenia. The nomogram to predict it provides useful information for the management of patients with CRPC treated with docetaxel chemotherapy. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess the readability of the web-based patient education material provided by the European Association of Urology. English patient education materials (PEM) as available in May 2017 were obtained from the EAU website. Each topic was analyzed separately using six well-established readability assessment tools, including Flesch-Kincaid Grade Level (FKGL), SMOG Grade Level (SMOG), Coleman-Liau Index (CLI), Gunning Fog Index (GFI), Flesch Reading Ease Formula (FRE) and Fry Readability Graph (FRG). A total of 17 main topics were identified of which separate basic and in-depth information is provided for 14 topics. Calculation of grade levels (FKGL, SMOG, CLI, GFI) showed readability scores of 7th-13th grade for basic information, 8th-15th grade for in-depth information and 7th-15th grade for single PEM. Median FRE score was 54 points (range 45-65) for basic information and 56 points (41-64) for in-depth information. The FRG as a graphical assessment revealed only 13 valid results with an approximate 8th-17th grade level. The EAU provides carefully worked out PEM for 17 urological topics. Although improved readability compared to similar analyses was found, a simplification of certain chapters might be helpful to facilitate better patient understanding.

2017-07-01

To propose a grading system of pterygium severity based on corneal higher-order irregularity (HOI) and to evaluate postoperative changes in corneal irregularity of the graded pterygia. In 268 eyes of 226 patients undergoing excision surgery of primary nasal pterygium, Placido corneal topography images were taken before and until 6 months after surgery. The best-corrected visual acuity (BCVA) and pterygium size with respect to the corneal diameter were also measured. HOI components within 1.0-, 3.0-, and 5.0-mm diameters were obtained using Fourier harmonic analysis of corneal topography data. With threshold levels when the HOIs for 3 diameters steeply increased, 4 levels of grading from 0 (mild) to 3 (severe) were determined. Associations of the grades with the preoperative surface regularity index (SRI), irregular components (IRRs) obtained from the 3.0-mm diameter Fourier analysis, and BCVA were examined. Time-course changes in the indexes after surgery were evaluated for each grade. There were 62, 65, 41, and 100 eyes in grades 0 to 3, respectively. Preoperatively, the SRI in grade 3 was significantly higher than in the other grades (P < 0.001), and the IRR and BCVA varied with the grade (P < 0.001). Between 1 and 6 months postoperatively, grade 3 pterygia showed significant changes in the SRI and IRR (P = 0.013 and 0.017, respectively), whereas there was no change after 3 months postoperatively in the SRI, IRR, and BCVA for all other grades. The proposed grading effectively classified the severity of pterygia and evaluated postoperative restoration of corneal irregularity. Using corneal topographic data allowed for objective evaluation of pterygium severity.

2013-01-01

Background The treatment of inborn errors of metabolism (IEM) has seen significant advances over the last decade. Many medicines have been developed and the survival rates of some patients with IEM have improved. Dosages of drugs used for the treatment of various IEM can be obtained from a range of sources but tend to vary among these sources. Moreover, the published dosages are not usually supported by the level of existing evidence, and they are commonly based on personal experience. Methods A literature search was conducted to identify key material published in English in relation to the dosages of medicines used for specific IEM. Textbooks, peer reviewed articles, papers and other journal items were identified. The PubMed and Embase databases were searched for material published since 1947 and 1974, respectively. The medications found and their respective dosages were graded according to their level of evidence, using the grading system of the Oxford Centre for Evidence-Based Medicine. Results 83 medicines used in various IEM were identified. The dosages of 17 medications (21%) had grade 1 level of evidence, 61 (74%) had grade 4, two medications were in level 2 and 3 respectively, and three had grade 5. Conclusions To the best of our knowledge, this is the first review to address this matter and the authors hope that it will serve as a quickly accessible reference for medications used in this important clinical field.

2016-10-01

Our objective is to describe off-label use of methotrexate in ectopic pregnancy treatment using evidence based medicine. The patient group includes all women with a pregnancy outside the usual endometrium, or of unknown location. Method used was a Medline search on ectopic pregnancy managed using methotrexate treatment; evidence synthesis was done based on this current literature analysis. Level of evidence (LE) were given according to the centre for evidence base medicine rules. Grade was proposed for guidelines but no recommendation was possible as misoprostol is off label use for all the indications studied. In the absence of any contraindication, the protocol recommended for medical treatment of ectopic pregnancy is a single intramuscular injection of methotrexate (MTX) at a dosage of 1mg/kg or 50mg/m(2) (Grade A). It can be repeated once at the same dose should the hCG concentration not fall sufficiently. Pretreatment laboratory results must include a complete blood count and kidney and liver function tests (in accordance with its marketing authorization). MTX is an alternative to conservative treatment such as laparoscopic salpingotomy for uncomplicated tubal pregnancy (Grade A) with pretreatment hCG levels≤5000IU/l (Grade B). Expectant management is preferred for hCG levels<1000IU/l or in the process of spontaneous decreasing (Grade B). Intramuscular MTX is also recommended after the failure of surgical salpingotomy (Grade C) or immediately after surgery, if monitoring is not possible. Except in special circumstances, a local insitu ultrasound-guided MTX injection is not recommended for unruptured tubal pregnancies (Grade B). In situ MTX is an option for treating cervical, interstitial, or cesarean-scar pregnancies (Grade C). In pregnancies of unknown location persisting more than 10days in an asymptomatic woman who has an hCG level>2000IU/l, routine MTX treatment is an option. MTX is not indicated for combination with treatments such as mifepristone or potassium. Copyright © 2016. Published by Elsevier Ireland Ltd.

Potential of MR spectroscopy for assessment of glioma grading.

PubMed

Bulik, Martin; Jancalek, Radim; Vanicek, Jiri; Skoch, Antonin; Mechl, Marek

2013-02-01

Magnetic resonance spectroscopy (MRS) is an imaging diagnostic method based that allows non-invasive measurement of metabolites in tissues. There are a number of metabolites that can be identified by standard brain proton MRS but only a few of them has a clinical significance in diagnosis of gliomas including N-acetylaspartate, choline, creatine, myo-inositol, lactate, and lipids. In this review, we describe potential of MRS for grading of gliomas. Low-grade gliomas are generally characterized by a relatively high concentration of N-acetylaspartate, low level of choline and absence of lactate and lipids. The increase in creatine concentration indicates low-grade gliomas with earlier progression and malignant transformation. Progression in grade of a glioma is reflected in the progressive decrease in the N-acetylaspartate and myo-inositol levels on the one hand and elevation in choline level up to grade III on the other. Malignant transformation of the glial tumors is also accompanied by the presence of lactate and lipids in MR spectra of grade III but mainly grade IV gliomas. It follows that MRS is a helpful method for detection of glioma regions with aggressive growth or upgrading due to favorable correlation of the choline and N-acetylaspartate levels with histopathological proliferation index Ki-67. Thus, magnetic resonance spectroscopy is also a suitable method for the targeting of brain biopsies. Gliomas of each grade have some specific MRS features that can be used for improvement of the diagnostic value of conventional magnetic resonance imaging in non-invasive assessment of glioma grade.

Guidelines for nonoperative management (NOM) of high-grade pancreatic injuries in children have not been established, and wide practice variability exists. The purpose of this study was to evaluate common clinical strategies across multiple pediatric trauma centers to develop a consensus-based standard clinical pathway. A multicenter, retrospective review was conducted of children with high-grade (American Association of Surgeons for Trauma grade III-V) pancreatic injuries treated with NOM between 2010 and 2015. Data were collected on demographics, clinical management, and outcomes. Eighty-six patients were treated at 20 pediatric trauma centers. Median age was 9 years (range, 1-18 years). The majority (73%) of injuries were American Association of Surgeons for Trauma grade III, 24% were grade IV, and 3% were grade V. Median time from injury to presentation was 12 hours and median ISS was 16 (range, 4-66). All patients had computed tomography scan and serum pancreatic enzyme levels at presentation, but serial enzyme level monitoring was variable. Pancreatic enzyme levels did not correlate with injury grade or pseudocyst development. Parenteral nutrition was used in 68% and jejunal feeds in 31%. 3Endoscopic retrograde cholangiopancreatogram was obtained in 25%. An organized peripancreatic fluid collection present for at least 7 days after injury was identified in 59% (42 of 71). Initial management of these included: observation 64%, percutaneous drain 24%, and endoscopic drainage 10% and needle aspiration 2%. Clear liquids were started at a median of 6 days (IQR, 3-13 days) and regular diet at a median of 8 days (IQR 4-20 days). Median hospitalization length was 13 days (IQR, 7-24 days). Injury grade did not account for prolonged time to initiating oral diet or hospital length; indicating that the variability in these outcomes was largely due to different surgeon preferences. High-grade pancreatic injuries in children are rare and significant variability exists in NOM strategies, which may affect outcomes and effective resource utilization. A standard clinical pathway is proposed. Therapeutic/care management, level V (case series).

Relationship Between Active Learning Methodologies and Community College Students' STEM Course Grades

NASA Astrophysics Data System (ADS)

Clark Lesko, Cherish Christina

Active learning methodologies (ALM) are associated with student success, but little research on this topic has been pursued at the community college level. At a local community college, students in science, technology, engineering, and math (STEM) courses exhibited lower than average grades. The purpose of this study was to examine whether the use of ALM predicted STEM course grades while controlling for academic discipline, course level, and class size. The theoretical framework was Vygotsky's social constructivism. Descriptive statistics and multinomial logistic regression were performed on data collected through an anonymous survey of 74 instructors of 272 courses during the 2016 fall semester. Results indicated that students were more likely to achieve passing grades when instructors employed in-class, highly structured activities, and writing-based ALM, and were less likely to achieve passing grades when instructors employed project-based or online ALM. The odds ratios indicated strong positive effects (greater likelihoods of receiving As, Bs, or Cs in comparison to the grade of F) for writing-based ALM (39.1-43.3%, 95% CI [10.7-80.3%]), highly structured activities (16.4-22.2%, 95% CI [1.8-33.7%]), and in-class ALM (5.0-9.0%, 95% CI [0.6-13.8%]). Project-based and online ALM showed negative effects (lower likelihoods of receiving As, Bs, or Cs in comparison to the grade of F) with odds ratios of 15.7-20.9%, 95% CI [9.7-30.6%] and 16.1-20.4%, 95% CI [5.9-25.2%] respectively. A white paper was developed with recommendations for faculty development, computer skills assessment and training, and active research on writing-based ALM. Improving student grades and STEM course completion rates could lead to higher graduation rates and lower college costs for at-risk students by reducing course repetition and time to degree completion.

The practice guidelines published by the American Gastroenterological Association (AGA) and the American College of Gastroenterology (ACG) are used to establish standards of care and improve patient outcomes. We examined the guidelines for quality of evidence, methods of grading evidence, and conflicts of interest (COIs). All 81 (AGA and ACG) guidelines available online on 26 July 2012 were reviewed for the presence of grading of evidence and COIs. In total, 570 recommendations were evaluated for level of evidence and methods used to grade the evidence. The data were evaluated in aggregate and by society. Only 31% (n=25) of the guidelines graded the levels of evidence. A total of 12 systems were used to grade the quality of evidence in these 25 guidelines. Of the 570 recommendations reviewed, only 29% (n=165) were supported by the highest quality of evidence, level A; 37% (n=210) level B, 29% (n=165) level C, and 5% (n=30) level D. Since 2007, 87% (n=13/15) of the ACG guidelines graded the evidence compared with only 33% of the AGA guidelines (n=4/12). Furthermore, 70% (n=57/81) of the guidelines failed to disclose any information regarding COIs. Of the 24 articles commenting on COIs, 67% reported COIs. Although the majority of the gastroenterology guidelines fail to grade the quality of evidence, more recent ACG guidelines grade majority of their recommendations. When the evidence is graded, most of the supporting evidence is based on lower-quality evidence. In addition, most of the guidelines fail to comment on COIs, and when disclosed, numerous COIs were present. This study highlights the critical need to revise the guideline development process. Future guidelines should clearly state the quality of evidence for their recommendations, utilize a standard grading system, and be transparent regarding all COIs.

Cytomorphologic spectrum of lymphocytic thyroiditis and correlation between cytological grading and biochemical parameters

PubMed Central

Anila, KR; Nayak, Nileena; Jayasree, K

2016-01-01

Introduction: Chronic lymphocytic thyroiditis [Hashimoto thyroiditis (HT)] is a common thyroid lesion diagnosed on fine-needle aspiration cytology (FNAC). Apart from FNAC, various other parameters, such as clinical features, ultrasonographic findings, antithyroid antibody levels, hormone profiles, and radionuclide thyroid scan, are also taken into consideration in making a diagnosis of HT. Aims: To grade lymphocytic thyroiditis based on the cytomorphology and to correlate the cytological grades with the levels of antithyroid peroxidase antibody (ATPO), antithyroglobulin antibody (ATG), and thyroid stimulating hormone (TSH). Materials and Methods: During a period of one and half years, 1,667 cases underwent FNAC of thyroid at our tertiary care center. Of these, 128 cases had cytological evidence of lymphocytic thyroiditis. Out of these, in 60 cases the levels of ATPO, ATG, and TSH were known. The cytological grades of lymphocytic thyroiditis in these cases were correlated with these parameters. Results: Out of the 60 cases, 55 were females. Age ranged from 5 years to 70 years, with majority of patients in third decade. Diffuse enlargement of thyroid was the commonest presentation. However, 14 cases presented with nodular disease. Majority of the patients had grade 1 thyroiditis (27 cases), followed by grade 2 thyroiditis (22 cases). Cytomorphology was diagnostic of thyroiditis in all 60 cases. ATPO was elevated in 57 cases and ATG was elevated in 40 cases. Elevated level of TSH was seen in only 18 cases. In 39 cases, TSH value was normal. There was no correlation between the cytological grades of thyroiditis and the levels of antithyroid antibodies and TSH. Conclusion: Lymphocytic infiltration of thyroid follicles is pathognomonic of lymphocytic thyroiditis. Positivity for antithyroid antibodies is strongly associated with HT but no correlation was observed between the grades of thyroiditis and the levels of ATPO, ATG, and TSH. PMID:27756987

What goal is of most worth? The effects of the implementation of the Texas Assessment of Knowledge and Skills on elementary science teaching

NASA Astrophysics Data System (ADS)

Rodgers, Pamela England

This qualitative, narrative study centered on the effects of the implementation of the science portion of the fifth grade Texas Assessment of Knowledge and Skills (TAKS) on the instruction of science at the elementary level, grades one through five. Fourteen teachers and five administrators were interviewed at two elementary schools (kindergarten through grade four) and one middle school (grades five and six). Classroom observations of each of the teachers were also conducted. The study focused on the effect of the implementation of the science TAKS on the amount of time spent on science as well as the instructional methods utilized in the elementary science classroom. Lower grade levels were found to have changed little in these areas unless strong administrative leadership---emphasizing curriculum alignment, providing adequate materials and facilities, and encouraging sustained, content-based professional development in science---was present in the school. At the fifth grade level, however, the amount of time spent on science had increased significantly, although the instructional methods utilized by the teachers were focused more often upon increasing ratings on the test rather than providing the research-based best practice methods of hands-on, inquiry-based science instruction. In addition, the study also explored the teachers' and administrators' perceptions of the state and local mandates concerning science instruction and preparation for the TAKS. Other topics that came to light during the course of the study included the teachers' views on accountability and the effects of the state assessments on children in their classrooms. It was found that most teachers readily accept accountability for themselves, but are opposed to one-shot high-stakes tests which they feel are damaging for their students emotionally and academically---adversely affecting their love of learning science.

To determine the readability of Internet-based patient education materials (IPEMs) created by United States hospitals and universities and clinical practices and miscellaneous health care-associated Web sites regarding uterine artery embolization (UAE) as a marker for IPEMs in general. Two hundred unique Web sites were evaluated for patient-related articles on UAE. Web sites produced by US hospitals and universities and clinical practices, as well as miscellaneous health care-associated Web sites meeting the Health on the Net Foundation Code of Conduct criteria were included in the database. By using mathematical regression algorithms based on word and sentence length to quantitatively analyze reading materials for language intricacy, readability of 40 UAE-related IPEMs was assessed with four indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (GFOG). Scores were evaluated against national recommendations, and intergroup analysis was performed. None of the IPEMs were written at or below the sixth-grade reading level, based on FKGL. The mean readability scores were as follows: FRES, 43.98; FKGL, 10.76; SMOG, 13.63; and GFOG, 14.55. These scores indicate that the readability of UAE IPEMs is written at an advanced level, significantly above the recommended 6th grade reading level (P<.05) determined by the United States Department of Health and Human Services. IPEMs related to UAE generated by hospitals, clinical practices, and miscellaneous health care-associated Web sites are written above the recommended sixth grade level. IPEMs for other disease entities may also reflect similar results. Copyright © 2013 SIR. Published by Elsevier Inc. All rights reserved.

Complications of pelvic organ prolapse surgery and methods of prevention.

PubMed

de Tayrac, Renaud; Sentilhes, Loic

2013-11-01

The aim was to review complications associated with pelvic organ prolapse surgery. Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials [RCT] or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 (case reports). The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. Grade A recommendation usually depends on consistent level 1 evidence. Grade B recommendation usually depends on consistent level 2 and/or 3 studies, or "majority evidence" from RCTs. Grade C recommendation usually depends on level 4 studies or "majority evidence from level 2/3 studies or Delphi processed expert opinion. Grade D "no recommendation possible" would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi. Transvaginal mesh has a higher re-operation rate than native tissue vaginal repairs (grade A). If a synthetic mesh is placed via the vaginal route, it is recommended that a macroporous polypropylene monofilament mesh should be used. At sacral colpopexy mesh should not be introduced or sutured via the vaginal route and silicone-coated polyester, porcine dermis, fascia lata and polytetrafluoroethylene meshes are not recommended as grafts. Hysterectomy should also be avoided (grade B). There is no evidence to recommend routine local or systemic oestrogen therapy before or after prolapse surgery using mesh. The first cases should be undertaken with the guidance of an experienced surgeon in the relevant technique (grade C). Expert opinion suggests that by whatever the surgical route pre-operative urinary tract infections are treated, smoking is ceased and antibiotic prophylaxis is undertaken. It is recommended that a non-absorbable synthetic mesh should not be inserted into the rectovaginal septum when a rectal injury occurs. The placement of a non-absorbable synthetic mesh into the vesicovaginal septum may be considered after a bladder injury has been repaired, if the repair is considered to be satisfactory. It is possible to perform a hysterectomy in association with the introduction of a non-absorbable synthetic mesh inserted vaginally, but this is not recommended routinely.

Based on the massive soil information in current soil quality grade evaluation, this paper constructed an intelligent classification approach of soil quality grade depending on classical sampling techniques and disordered multiclassification Logistic regression model. As a case study to determine the learning sample capacity under certain confidence level and estimation accuracy, and use c-means algorithm to automatically extract the simplified learning sample dataset from the cultivated soil quality grade evaluation database for the study area, Long chuan county in Guangdong province, a disordered Logistic classifier model was then built and the calculation analysis steps of soil quality grade intelligent classification were given. The result indicated that the soil quality grade can be effectively learned and predicted by the extracted simplified dataset through this method, which changed the traditional method for soil quality grade evaluation. ?? 2011 IEEE.

This study compared the combination of estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR) vs. eGFR and urine protein reagent strip testing to determine chronic kidney disease (CKD) prevalence, and each method's ability to predict the risk for cardiovascular events in the general Japanese population. Baseline data including eGFR, UACR, and urine dipstick tests were obtained from the general population (n = 22 975). Dipstick test results (negative, trace, positive) were allocated to three levels of UACR (<30, 30-300, >300), respectively. In accordance with Kidney Disease Improving Global Outcomes CKD prognosis heat mapping, the cohort was classified into four risk grades (green: grade 1; yellow: grade 2; orange: grade 3, red: grade 4) based on baseline eGFR and UACR levels or dipstick tests. During the mean follow-up period of 5.6 years, 708 new onset cardiovascular events were recorded. For CKD identified by eGFR and dipstick testing (dipstick test ≥ trace and eGFR <60 mL/min/1.73 m(2)), the incidence of CKD was found to be 9 % in the general population. In comparison to non-CKD (grade 1), although cardiovascular risk was significantly higher in risk grades ≥3 (relative risk (RR) = 1.70; 95 % CI: 1.28-2.26), risk predictive ability was not significant in risk grade 2 (RR = 1.20; 95 % CI: 0.95-1.52). When CKD was defined by eGFR and UACR (UACR ≥30 mg/g Cr and eGFR <60 mL/min/1.73 m(2)), prevalence was found to be 29 %. Predictive ability in risk grade 2 (RR = 1.41; 95 % CI: 1.19-1.66) and risk grade ≥3 (RR = 1.76; 95 % CI: 1.37-2.28) were both significantly greater than for non-CKD. Reclassification analysis showed a significant improvement in risk predictive abilities when CKD risk grading was based on UACR rather than on dipstick testing in this population (p < 0.001). Although prevalence of CKD was higher when detected by UACR rather than urine dipstick testing, the predictive ability for cardiovascular events from UACR-based risk grading was superior to that of dipstick-based risk grading in the general population.

Performance-based alternative assessments as a means of eliminating gender achievement differences on science tests

Historically, researchers have reported an achievement difference between females and males on standardized science tests. These differences have been reported to be based upon science knowledge, abstract reasoning skills, mathematical abilities, and cultural and social phenomena. This research was designed to determine how mastery of specific science content from public school curricula might be evaluated with performance-based assessment models, without producing gender achievement differences. The assessment instruments used were Harcourt Brace Educational Measurement's GOALSsp°ler: A Performance-Based Measure of Achievement and the performance-based portion of the Stanford Achievement Testspcopyright, Ninth Edition. The identified independent variables were test, gender, ethnicity, and grade level. A 2 x 2 x 6 x 12 (test x gender x ethnicity x grade) factorial experimental design was used to organize the data. A stratified random sample (N = 2400) was selected from a national pool of norming data: N = 1200 from the GOALSsp°ler group and N = 1200 from the SAT9spcopyright group. The ANOVA analysis yielded mixed results. The factors of test, gender, ethnicity by grade, gender by grade, and gender by grade by ethnicity failed to produce significant results (alpha = 0.05). The factors yielding significant results were ethnicity, grade, and ethnicity by grade. Therefore, no significant differences were found between female and male achievement on these performance-based assessments.

How reliable is computerized assessment of readability?

Mailloux, S L; Johnson, M E; Fisher, D G; Pettibone, T J

1995-01-01

To assess the consistency and comparability of readability software programs, four software programs (Corporate Voice, Grammatix IV, Microsoft Word for Windows, and RightWriter) were compared. Standard materials included 28 pieces of printed educational materials on human immunodeficiency virus/acquired immunodeficiency syndrome distributed nationally and the Gettysburg Address. Statistical analyses for the educational materials revealed that each of the three formulas assessed (Flesch-Kincaid, Flesch Reading Ease, and Gunning Fog Index) provided significantly different grade equivalent scores and that the Microsoft Word program provided significantly lower grade levels and was more inconsistent in the scores provided. For the Gettysburg Address, considerable variation was revealed among formulas, with the discrepancy being up to two grade levels. When averaging across formulas, there was a variation of 1.3 grade levels between the four software programs. Given the variation between formulas and programs, implications for decisions based on results of these software programs are provided.

There are few tissue-based biomarkers that can accurately predict prostate cancer (PCa) progression and aggressiveness. We sought to evaluate the clinical utility of prostate and breast overexpressed 1 (PBOV1) as a potential PCa biomarker. Patient tumor samples were designated by Grade Groups using the 2014 Gleason grading system. Primary radical prostatectomy tumors were obtained from 48 patients and evaluated for PBOV1 levels using Western blot analysis in matched cancer and benign cancer-adjacent regions. Immunohistochemical evaluation of PBOV1 was subsequently performed in 80 cancer and 80 benign cancer-adjacent patient samples across two tissue microarrays (TMAs) to verify protein levels in epithelial tissue and to assess correlation between PBOV1 proteins and nuclear architectural changes in PCa cells. Digital histomorphometric analysis was used to track 22 parameters that characterized nuclear changes in PBOV1-stained cells. Using a training and test set for validation, multivariate logistic regression (MLR) models were used to identify significant nuclear parameters that distinguish Grade Group 3 and above PCa from Grade Group 1 and 2 PCa regions. PBOV1 protein levels were increased in tumors from Grade Group 3 and above (GS 4 + 3 and ≥ 8) regions versus Grade Groups 1 and 2 (GS 3 + 3 and 3 + 4) regions (P = 0.005) as assessed by densitometry of immunoblots. Additionally, by immunoblotting, PBOV1 protein levels differed significantly between Grade Group 2 (GS 3 + 4) and Grade Group 3 (GS 4 + 3) PCa samples (P = 0.028). In the immunohistochemical analysis, measures of PBOV1 staining intensity strongly correlated with nuclear alterations in cancer cells. An MLR model retaining eight parameters describing PBOV1 staining intensity and nuclear architecture discriminated Grade Group 3 and above PCa from Grade Group 1 and 2 PCa and benign cancer-adjacent regions with a ROC-AUC of 0.90 and 0.80, respectively, in training and test sets. Our study demonstrates that the PBOV1 protein could be used to discriminate Grade Group 3 and above PCa. Additionally, the PBOV1 protein could be involved in modulating changes to the nuclear architecture of PCa cells. Confirmatory studies are warranted in an independent population for further validation. © 2018 Wiley Periodicals, Inc.

Personal computer based flight simulators are expanding opportunities for providing low-cost pilot training. One advantage of these devices is the opportunity to incorporate instructional features into training scenarios that might not be cost effective with earlier systems. Research was conducted to evaluate the utility of different instructional features using a coordinated level turn as an aircraft maneuvering task. In study I, a comparison was made between automated computer grades of performance with certified flight instructors grades. Every one of the six student volunteers conducted a flight with level turns at two different bank angles. The automated computer grades were based on prescribed tolerances on bank angle, airspeed and altitude. Two certified flight instructors independently examined the video tapes of heads up and instrument displays of the flights and graded them. The comparison of automated grades with the instructors grades was based on correlations between them. In study II, a 2x2 between subjects factorial design was used to devise and conduct an experiment. Comparison was made between real time training and above real time training and between feedback and no feedback in training. The performance measure to monitor progress in training was based on deviations in bank angle and altitude. The performance measure was developed after completion of the experiment including the training and test flights. It was not envisaged before the experiment. The experiment did not include self- instructions as it was originally planned, although feedback by experimenter to the trainee was included in the study.

(1) What is the optimal role of external beam radiotherapy in the management of adult patients with newly diagnosed low-grade glioma (LGG) in terms of improving outcome (i.e., survival, complications, seizure control or other reported outcomes of interest)? (2) Which radiation strategies (dose, timing, fractionation, stereotactic radiation, brachytherapy, chemotherapy) improve outcomes compared to standard external beam radiation therapy in the initial management of low grade gliomas in adults? (3) Do specific factors (e.g., age, volume, extent of resection, genetic subtype) identify subgroups with better outcomes following radiation therapy than the general population of adults with newly diagnosed low-grade gliomas? These recommendations apply to adults with newly diagnosed diffuse LGG. OUTCOMES IN ADULT PATIENTS WITH NEWLY DIAGNOSED LOW GRADE GLIOMA TREATED WITH RADIOTHERAPY: Level I Radiotherapy is recommended in the management of newly diagnosed low-grade glioma in adults to prolong progression free survival, irrespective of extent of resection. Level II Radiotherapy is recommended in the management of newly diagnosed low grade glioma in adults as an equivalent alternative to observation in preserving cognitive function, irrespective of extent of resection. Level III Radiotherapy is recommended in the management of newly diagnosed low grade glioma in adults to improve seizure control in patients with epilepsy and subtotal resection. Level III Radiotherapy is recommended in the management of newly diagnosed low-grade glioma in adults to prolong overall survival in patients with subtotal resection. Level III Consideration of the risk of radiation induced morbidity, including cognitive decline, imaging abnormalities, metabolic dysfunction and malignant transformation, is recommended when the delivery of radiotherapy is selected in the management of newly diagnosed low-grade glioma in adults. STRATEGIES OF RADIOTHERAPY IN ADULT PATIENTS WITH NEWLY DIAGNOSED LOW GRADE GLIOMA: Level I Lower dose radiotherapy is recommended as an equivalent alternative to higher dose immediate postoperative radiotherapy (45-50.4 vs. 59.4-64.8 Gy) in the management of newly diagnosed low-grade glioma in adults with reduced toxicity. Level III Delaying radiotherapy until recurrence or progression is recommended as an equivalent alternative to immediate postoperative radiotherapy in the management of newly diagnosed low-grade glioma in adults but may result in shorter time to progression. Level III The addition of chemotherapy to radiotherapy is not recommended over whole brain radiotherapy alone in the management of low-grade glioma, as it provides no additional survival benefit. Level III Limited-field radiotherapy is recommended over whole brain radiotherapy in the management of low-grade glioma. Level III Either stereotactic radiosurgery or brachytherapy are recommended as acceptable alternatives to external radiotherapy in selected patients. PROGNOSTIC FACTORS IN ADULT PATIENTS WITH NEWLY DIAGNOSED LOW GRADE GLIOMA TREATED WITH RADIOTHERAPY: Level II It is recommended that age greater than 40 years, astrocytic pathology, diameter greater than 6 cm, tumor crossing the midline and preoperative neurological deficit be considered as negative prognostic indicators when predicting overall survival in adult low grade glioma patients treated with radiotherapy. Level II It is recommended that smaller tumor size, extent of surgical resection and higher mini-mental status exam be considered as positive prognostic indicators when predicting overall survival and progression free survival in patients in adult low grade glioma patients treated with radiotherapy. Level III It is recommended that seizures at presentation, presence of oligodendroglial histological component and 1p19q deletion (along with additional relevant factors-see Table 1) be considered as positive prognostic indicators when predicting response to radiotherapy in adults with low grade gliomas. Level III It is recommended that increasing age, decreasing performance status, decreasing cognition, presence of astrocytic histological component (along with additional relevant factors (see Tables 1, 2) be considered as negative prognostic indicators when predicting response to radiotherapy.

School-based exposure to hazardous air pollutants and grade point average: A multi-level study.

2016-05-01

The problem of environmental health hazards around schools is serious but it has been neglected by researchers and analysts. This is concerning because children are highly susceptible to the effects of chemical hazards. Some ecological studies have demonstrated that higher school-level pollution is associated with lower aggregate school-level standardized test scores likely, related to increased respiratory illnesses and/or impaired cognitive development. However, an important question remains unexamined: How do school-level exposures impact individual children's academic performance? To address this, we obtained socio-demographic and grades data from the parents of 1888 fourth and fifth grade children in the El Paso (Texas, USA) Independent School District in 2012. El Paso is located on the US-side of the Mexican border and has a majority Mexican-origin population. School-based hazardous air pollution (HAP) exposure was calculated using census block-level US Environmental Protection Agency National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter (PM). School-level demographics were obtained from the school district. Multi-level models adjusting for individual-level covariates (e.g., age, sex, race/ethnicity, English proficiency, and economic deprivation) and school-level covariates (e.g., percent of students economically disadvantaged and student-teacher ratio) showed that higher school-level HAPs were associated with lower individual-level grade point averages. An interquartile range increase in school-level HAP exposure was associated with an adjusted 0.11-0.40 point decrease in individual students' grade point averages (GPAs), depending on HAP type and emission source. Respiratory risk from HAPs had a larger effect on GPA than did diesel PM risk. Non-road mobile and total respiratory risk had the largest effects on children's GPA of all HAP variables studied and only mother's level of education had a larger effect than those two variables on children's GPA. The five school-level demographic indicators were only weakly associated with GPA. The study findings indicate the need for regulations on school siting and adjacent land uses to protect children's environmental health. Copyright © 2016 Elsevier Inc. All rights reserved.

A quantitative examination of public school student attitudes toward science

NASA Astrophysics Data System (ADS)

Schuchman, Matthew

There is a deficit of male and female students entering the fields of math and science, and the need for highly educated individuals in these areas is expected to increase. While various factors may play a role in creating this deficit, there is a lack of research on one factor, that of student attitudes toward science. The theories of social aspects, how children learn and how teachers teach provided the framework for an examination of public school student attitudes toward science. The purpose of this study was to determine if there is a significant difference in attitudes toward science in Grades 4-12 based on gender and grade level. Using a quantitative one-shot case study preexperimental design, the study described the relationships in student attitudes toward science and how those relationships change with grade and gender. This study investigated the relationship in attitudes toward science in different grade levels, the relationship in male and female attitudes toward science in different grade levels, and the difference in attitudes toward science between male and female students. The Kruskal-Wallis test and the nonparametric independent samples test for gender differences were performed to examine grade level, gender, and attitudes toward science. The convenience sample of 1,008 students was drawn from a population of approximately 1,200 students enrolled in Grades 4 through 12 in a rural, public school district in the northeastern United States. The data analysis revealed no difference in male attitudes toward science, but did reveal a significant difference in female attitudes toward science between different grade levels, (H(8) = 32.773, p < .000). Implications for social change include an improved student attitude toward science, which increases educational opportunities and career options for underrepresented groups.

This study investigated the prevalence of bullying and victimization among students in grades 7 and 8. It also explored the relationship of bullying and victimization to gender, grade level, ethnicity, self-esteem, and depression. Three survey instruments were used to obtain data from a convenience sample of 454 public school students. Twenty-four percent reported bullying involvement. Chi-square tests indicated significantly more male than female bullying involvement, seventh graders reported more involvement than did eighth graders, and there were no statistically significant differences in involvement based on ethnicity. Both bullies and victims manifested higher levels of depression than did students who were neither bullies nor victims. There were no significant differences between groups in terms of self-esteem.

This research discusses learning continuum development for designing a curriculum. The objective of this study is to gather the opinion of public junior and senior high school teachers about learning continuum based on student's level of competence and specific pedagogical material in classification topics. This research was conducted in Yogyakarta province from October 2016 to January 2017. This research utilizes a descriptive survey method. Respondents in this study consist of 281 science teachers at junior and senior high school in Yogyakarta city and 4 regencies namely Sleman, Bantul, Kulonprogo, and Gunung Kidul. The sample were taken using a census. The collection of data used questionnaire that had been validated from the aspects of construct validity and experts judgements. Data were analyzed using a descriptive analysis technique. The results of the analysis show that the opinions of teachers regarding specific pedagogical material in classification topics of living things at the junior high school taught in grade VII to the ability level of C2 (Understanding). At senior high school level, it is taught in grade X with the ability level C2 (Understanding). Based on these results, it can be concluded that the opinions of teachers still refer to the current syllabus and curriculum so that the teachers do not have pure opinions about the student's competence level in classification topics that should be taught at the level of the grade in accordance with the level of corresponding competency.

Tian, Chenlu; Champlin, Sara; Mackert, Michael; Lazard, Allison; Agrawal, Deepak

2014-08-01

Colorectal cancer (CRC) screening rates in the Unites States are still below target level. Web-based patient education materials are used by patients and providers to provide supplemental information on CRC screening. Low literacy levels and patient perceptions are significant barriers to screening. There are little data on the quality of these online materials from a health literacy standpoint or whether they address patients' perceptions. To evaluate the readability, suitability, and health content of web-based patient education materials on colon cancer screening. Descriptive study. Web-based patient materials. Twelve reputable and popular online patient education materials were evaluated. Readability was measured by using the Flesch-Kincaid Reading Grade Level, and suitability was determined by the Suitability Assessment of Materials, a scale that considers characteristics such as content, graphics, layout/typography, and learning stimulation. Health content was evaluated within the framework of the Health Belief Model, a behavioral model that relates patients' perceptions of susceptibility to disease, severity, and benefits and barriers to their medical decisions. Each material was scored independently by 3 reviewers. Flesch-Kincaid Reading Grade Level score, Suitability Assessment of Materials score, health content score. Readability for 10 of 12 materials surpassed the maximum recommended sixth-grade reading level. Five were 10th grade level and above. Only 1 of 12 materials received a superior suitability score; 3 materials received inadequate scores. Health content analysis revealed that only 50% of the resources discussed CRC risk in the general population and <25% specifically addressed patients at high risk, such as African Americans, smokers, patients with diabetes, and obese patients. For perceived barriers to screening, only 8.3% of resources discussed embarrassment, 25% discussed pain with colonoscopy, 25% addressed cost of colonoscopy, and none specifically mentioned the need to get colonoscopy when no symptoms are present. No material discussed the social benefits of screening. Descriptive design. Most online patient education materials for CRC screening are written beyond the recommended sixth-grade reading level, with suboptimal suitability. Health content is lacking in addressing key perceived risks, barriers, and benefits to CRC screening. Developing more appropriate and targeted patient education resources on CRC may improve patient understanding and promote screening. Copyright © 2014 American Society for Gastrointestinal Endoscopy.

Americans are increasingly turning to the Internet as a source of health care information. These online resources should be written at a level readily understood by the average American. This study evaluates the readability of online patient education information available from the American Academy of Otolaryngology--Head and Neck Surgery Foundation (AAO-HNSF) professional Web site using 7 different assessment tools that analyze the materials for reading ease and grade level of its target audience. Analysis of Internet-based patient education material from the AAO-HNSF Web site. Online patient education material from the AAO-HNSF was downloaded in January 2012 and assessed for level of readability using the Flesch Reading Ease, Flesch-Kincaid Grade Level, SMOG grading, Coleman-Liau Index, Gunning-Fog Index, Raygor Readability Estimate graph, and Fry Readability graph. The text from each subsection was pasted as plain text into Microsoft Word document, and each subsection was subjected to readability analysis using the software package Readability Studio Professional Edition Version 2012.1. All health care education material assessed is written between an 11th grade and graduate reading level and is considered "difficult to read" by the assessment scales. Online patient education materials on the AAO-HNSF Web site are written above the recommended 6th grade level and may need to be revised to make them more easily understood by a broader audience.

Gleason grading is the best independent predictor for prostate cancer (PCa) progression. Recently, a new PCa grading system has been introduced by the International Society of Urological Pathology (ISUP) and is recommended by the World Health Organization (WHO). Following studies observed more accurate and simplified grade stratification of the new system. Aim of this study was to compare the prognostic value of the new grade groups compared to the former Gleason Grading and to determine whether re-definition of Gleason Pattern 4 might reduce upgrading from prostate biopsy to radical prostatectomy (RP) specimen. A cohort of men undergoing RP from 2002 to 2015 at the Hospital of Goeppingen (Goeppingen, Germany) was used for this study. In total, 339 pre-operative prostatic biopsies and corresponding RP specimens, as well as additional 203 RP specimens were re-reviewed for Grade Groups according to the ISUP. Biochemical recurrence-free survival (BFS) after surgery was used as endpoint to analyze prognostic significance. Other clinicopathological data included TNM-stage and pre-operative PSA level. Kaplan-Meier analysis revealed risk stratification of patients based on both former Gleason Grading and ISUP Grade Groups, and was statistically significant using the log-rank test ( p  < 0.001). Both grading systems significantly correlated with TNM-stage and pre-operative PSA level ( p  < 0.001). Higher tumor grade in RP specimen compared to corresponding pre-operative biopsy was observed in 44 and 34.5% of cases considering former Gleason Grading and ISUP Grade Groups, respectively. Both, former Gleason Grading and ISUP Grade Groups predict survival when applied on tumors in prostatic biopsies as well as RP specimens. This is the first validation study on a large representative German community-based cohort to compare the former Gleason Grading with the recently introduced ISUP Grade Groups. Our data indicate that the ISUP Grade Groups do not improve predictive value of PCa grading and might be less sensitive in deciphering tumors with 3 + 4 and 4 + 3 pattern on RP specimen. However, the Grade Group system results less frequently in an upgrading from biopsy to the corresponding RP specimens, indicating a lower risk to miss potentially aggressive tumors not represented on biopsies.

The level of Galectin-3 (Gal-3) protein purportedly reflects an ongoing cardiac fibrotic process and has been associated with ventricular remodeling, which is instrumental in the development of heart failure with preserved ejection fraction (HFpEF) syndrome. The aim of this study was to investigate the potential use of Gal-3 in improved characterization of the grades of diastolic dysfunction as defined by echocardiography. Seventy HFpEF patients undergoing routine echocardiography were prospectively enrolled in the present monocentric study. Blood samples for measurements of Gal-3 and amino-terminal pro-brain natriuretic peptide (NT-proBNP) were collected within 24 hours pre- or post-echocardiographic examination. The classification of patients into subgroups based on diastolic dysfunction grade permitted detailed statistical analyses of the derived data. The Gal-3 serum levels of all patients corresponded to echocardiographic indices, suggesting HFpEF (E/A, P=0.03 and E/E', P=0.02). Gal-3 was also associated with progressive diastolic dysfunction, and increased levels corresponded to the course of disease (P=0.012). Detailed analyses of ROC curves suggested that Gal-3 levels could discriminate patients with grade III diastolic dysfunction (area under the curve [AUC]=0.770, P=0.005). Gal-3 demonstrates remarkable effectiveness in the diagnosis of patients suffering from severe grade diastolic dysfunction. Increasing levels of Gal-3 possibly reflect the progressive course of HFpEF, as classified by the echocardiographic grades of diastolic dysfunction. © The Korean Society for Laboratory Medicine.

The majority of Americans use the Internet daily, if not more often, and many search online for health information to better understand a diagnosis they have been given or to research treatment options. The average American reads at an eighth-grade level. The purpose of this study is to evaluate the readability of online patient education materials on the websites of 14 professional organizations representing the major internal medicine subspecialties. We used ten well-established quantitative readability scales to assess written text from patient education materials published on the websites of the major professional organizations representing the following subspecialty groups: allergy and immunology, cardiology, endocrinology, gastroenterology, geriatrics, hematology, hospice and palliative care, infectious disease, nephrology, oncology, pulmonology and critical care, rheumatology, sleep medicine, and sports medicine. Collectively the 540 articles analyzed were written at an 11th-grade level (SD 1.4 grade levels). The sleep medicine and nephrology websites had the most readable materials, written at an academic grade level of 8.5 ± 1.5 and 9.0 ± 0.2, respectively. Material at the infectious disease site was written at the most difficult level, with average readability corresponding to grades 13.9 ± 0.3. None of the patient education materials we reviewed conformed to the American Medical Association (AMA) and the National Institutes of Health (NIH) guidelines requiring that patient education articles be written at a third- to seventh-grade reading level. If these online resources were rewritten, it is likely that more patients would derive benefit from reading them.

In this article, we report the grades for the second New Zealand Report Card on Physical Activity for Children and Youth, which represents a synthesis of available New Zealand evidence across 9 core indicators. An expert panel of physical activity (PA) researchers collated and reviewed available nationally representative survey data between March and May 2016. In the absence of new data, (2014-2016) regional level data were used to inform the direction of existing grades. Grades were assigned based on the percentage of children and youth meeting each indicator: A is 81% to 100%; B is 61% to 80%; C is 41% to 60%, D is 21% to 40%; F is 0% to 20%; INC is Incomplete data. Overall PA, Active Play, and Government Initiatives were graded B-; Community Environments was graded B; Sport Participation and School Environment received a C+; Sedentary Behaviors and Family/Peer Support were graded C; and Active Travel was graded C-. Overall PA participation was satisfactory for young children but not for youth. The grade for PA decreased slightly from the 2014 report card; however, there was an improvement in grades for built and school environments, which may support regional and national-level initiatives for promoting PA.

Patient education is critical in obtaining informed consent and reducing preoperative anxiety. Written patient education material (PEM) can supplement verbal communication to improve understanding and satisfaction. Published guidelines recommend that health information be presented at or below a sixth-grade reading level to facilitate comprehension. We investigate the grade level of online PEMs regarding parathyroid surgery. A popular internet search engine was used to identify PEM discussing parathyroid surgery. Four formulas were used to calculate readability scores: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Gunning Frequency of Gobbledygook (GFOG), and Simple Measure of Gobbledygook (SMOG). Thirty web-based articles discussing parathyroid surgery were identified. The average FRE score was 42.8 (±1 standard deviation [SD] 16.3; 95% confidence interval [CI], 36.6-48.8; range, 6.1-71.3). The average FKGL score was 11.7 (±1 SD 3.3; 95% CI, 10.5-12.9; range, 6.1-19.0). The SMOG scores averaged 14.2 (±1 SD 2.6; 95% CI, 13.2-15.2; range, 10.7-21.9), and the GFOG scores averaged 15.0 (±1 SD 3.5; 95% CI, 13.7-16.3; range, 10.6-24.8). Online PEM on parathyroid surgery is written above the recommended sixth-grade reading level. Improving readability of PEM may promote better health education and compliance. © The Author(s) 2015.

Purpose To systematically review the scientific level of evidence for the ‘Top 3’ risk factors, screening tests and preventative exercises identified by a previously published survey of 44 premier league football (soccer) teams. Also, to provide an overall scientific level of evidence and graded recommendation based on the current research literature. Methods A systematic literature search (Pubmed [MEDLINE], SportDiscus, PEDRO and Cochrane databases). The quality of the articles was assessed and a level of evidence (1++ to 4) was assigned. Level 1++ corresponded to the highest level of evidence available and 4, the lowest. A graded recommendation (A: strong, B: moderate, C: weak, D: insufficient evidence to assign a specific recommendation) for use in the practical setting was given. Results Fourteen studies were analysed. The overall level of evidence for the risk factors previous injury, fatigue and muscle imbalance were 2++, 4 and ‘inconclusive’, respectively. The graded recommendation for functional movement screen, psychological questionnaire and isokinetic muscle testing were all ‘D’. Hamstring eccentric had a weak graded ‘C’ recommendation, and eccentric exercise for other body parts was ‘D’. Balance/proprioception exercise to reduce ankle and knee sprain injury was assigned a graded recommendation ‘D’. Conclusions The majority of perceptions and practices of premier league teams have a low level of evidence and low graded recommendation. This does not imply that these perceptions and practices are not important or not valid, as it may simply be that they are yet to be sufficiently validated or refuted by research. PMID:25576530

We aimed to determine the predictability of clinical and laboratory variables for vesicoureteral reflux (VUR) in children with urinary tract infection (UTI). Data of children with febrile UTI who underwent voiding cystoureterography between 2002 and 2005 were evaluated retrospectively for clinical (age, gender, fever > or = 38.5 degrees C, recurrent UTI), laboratory [leukocytosis, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), pyuria, serum creatinine (S(Cr))] and imaging (renal ultrasonography) variables. Children with VUR (group 1) vs. no VUR (group 2) and children with high-grade (III-V) VUR (group 3) vs. no or low-grade (I-II) VUR (group 4) were compared. Among 88 patients (24 male), 38 had VUR and 21 high-grade VUR. Fever > or = 38.5 degrees C was associated with VUR [odds ratio (OR): 7.5]. CRP level of 50 mg/l was the best cut-off level for predicting high-grade VUR (OR 15.5; discriminative ability 0.89 +/- 0.05). Performing voiding cystourethrography based on this CRP level would result in failure to notice 9% of patients with high-grade VUR, whereas 69% of children with no/low-grade VUR would be spared from this invasive test. In conclusion, fever > or = 38 degrees C and CRP > 50 mg/l seem to be potentially useful clinical predictors of VUR and high-grade VUR, respectively, in pediatric patients with UTI. Further validation of these findings could limit unnecessary voiding cystourethrography.

Readability Levels of Dental Patient Education Brochures.

2016-02-01

The objective of this study was to evaluate dental patient education brochures produced since 2000 to determine if there is any change in the Flesch-Kincaid grade level readability. A convenience sample of 36 brochures was obtained for analysis of the readability of the patient education material on multiple dental topics. Readability was measured using the Flesch-Kincaid Grade Level through Microsoft Word. Pearson's correlation was used to describe the relationship among the factors of interest. Backward model selection of multiple linear regression model was used to investigate the relationship between Flesch-Kincaid Grade level and a set of predictors included in this study. A convenience sample (n=36) of dental education brochures produced from 2000 to 2014 showed a mean Flesch-Kincaid reading grade level of 9.15. Weak to moderate correlations existed between word count and grade level (r=0.40) and characters count and grade level (r=0.46); strong correlations were found between grade level and average words per sentence (r=0.70), average characters per word (r=0.85) and Flesch Reading Ease (r=-0.98). Only 1 brochure out of the sample met the recommended sixth grade reading level (Flesch-Kincaid Grade Level 5.7). Overall, the Flesch-Kincaid Grade Level of all brochures was significantly higher than the recommended sixth grade reading level (p<0.0001). The findings from this study demonstrated that there has generally been an improvement in the Flesch-Kincaid grade level readability of the brochures. However, the majority of the brochures analyzed are still testing above the recommended sixth grade reading level. Copyright © 2016 The American Dental Hygienists’ Association.

2018-04-26

The binary approach to the diagnosis of Chronic Bronchitis (CB) is a major barrier to the study of the disease. We investigated whether severity of productive cough can be graded using symptoms and presence of fixed airflow obstruction (FAO), and whether the severity correlates with health status, exposures injurious to the lung, biomarkers of inflammation, and measures of airway wall thickening. Findings from a cross-sectional sample of 1,422 participants from the Lovelace Smokers Cohort (LSC) were validated in 4,488 participants from the COPDGene cohort (COPDGene). Health status was based on the St. George's Respiratory Questionnaire, and Medical Outcomes Study 36-Item Short Form Health Survey. Circulating CC16 levels were quantified by ELISA (LSC), and airway wall thickening was measured using computed tomography (COPDGene). FAO was defined as postbronchodilator FEV 1 /FVC <0.7. The presence and duration of productive cough and presence of FAO or wheeze were graded into Healthy Smokers, Productive Cough (PC), Chronic PC, PC with Signs of Airflow Obstruction, and Chronic PC with Signs of Airflow Obstruction. In both cohorts, higher grade of severity correlated with lower health status, greater frequency of injurious exposures, greater airway wall thickening, and lower circulating CC16 levels. Further, longitudinal follow-up suggested that disease resolution can occur at every grade of severity but is more common in groups of lower severity and least common once airway remodeling develops. Therefore, severity of productive cough can be graded based on symptoms and FAO and early intervention may benefit patients by changing the natural history of disease.

The present article summarizes the results from the Active Healthy Kids Canada 2012 Report Card on Physical Activity for Children and Youth. The Report Card assessed the physical activity levels of Canadian children and youth nationally, and the initiatives of public and nongovernment sectors to promote and facilitate physical activity opportunities for children and youth in Canada. Based on a comprehensive collection of data that were analyzed and/or published in 2011, 24 indicators relating to physical activity were graded. The Physical Activity Levels indicator, the core indicator of the Report Card, was graded an ‘F’ for the sixth consecutive year. Although the majority of grades remained unchanged from the previous year, four grades improved and two worsened. These results suggest that few Canadian children and youth have sufficient physical activity levels, and that greater efforts are required across sectors to promote and facilitate physical activity opportunities for children and youth in Canada.

The purpose of the study was to examine the effects of two instructional approaches designed to improve the reading fluency of 2nd-grade children. The first approach was based on Stahl and Heubach’s (2005) fluency-oriented reading instruction (FORI) and involved the scaffolded, repeated reading of grade-level texts over the course of each week. The second was a wide-reading approach that also involved scaffolded instruction. hut that incorporated the reading of 3 different grade-level texts each week and provicled significantly less opportunity for repetition. By the end of the school year. FORI and wide-reading approaches showed similar benefits for standardized measures of word reading efficiency and reading comprehension skills compared to control approachcs. although the benefits of the wide-reading approach emerged earlier and included oral text reading fluency skill. Thus, we conclude that fluency instruction that emphasizes extensive oral reading of grade-level text using scaffolded approaches is effective for promoting reading development in young learners.

Background A number of approaches have been used to grade levels of evidence and the strength of recommendations. The use of many different approaches detracts from one of the main reasons for having explicit approaches: to concisely characterise and communicate this information so that it can easily be understood and thereby help people make well-informed decisions. Our objective was to critically appraise six prominent systems for grading levels of evidence and the strength of recommendations as a basis for agreeing on characteristics of a common, sensible approach to grading levels of evidence and the strength of recommendations. Methods Six prominent systems for grading levels of evidence and strength of recommendations were selected and someone familiar with each system prepared a description of each of these. Twelve assessors independently evaluated each system based on twelve criteria to assess the sensibility of the different approaches. Systems used by 51 organisations were compared with these six approaches. Results There was poor agreement about the sensibility of the six systems. Only one of the systems was suitable for all four types of questions we considered (effectiveness, harm, diagnosis and prognosis). None of the systems was considered usable for all of the target groups we considered (professionals, patients and policy makers). The raters found low reproducibility of judgements made using all six systems. Systems used by 51 organisations that sponsor clinical practice guidelines included a number of minor variations of the six systems that we critically appraised. Conclusions All of the currently used approaches to grading levels of evidence and the strength of recommendations have important shortcomings. PMID:15615589

Online health information should meet the reading level for the general public (set at sixth-grade level). Readability is a key requirement for information to be helpful and improve quality of care. The authors conducted a systematic review to evaluate the readability of online health information in the United States and Canada. Out of 3743 references, the authors included 157 cross-sectional studies evaluating 7891 websites using 13 readability scales. The mean readability grade level across websites ranged from grade 10 to 15 based on the different scales. Stratification by specialty, health condition, and type of organization producing information revealed the same findings. In conclusion, online health information in the United States and Canada has a readability level that is inappropriate for general public use. Poor readability can lead to misinformation and may have a detrimental effect on health. Efforts are needed to improve readability and the content of online health information.

Integration of Place-Based Education Into Science Classes From Prekindergarten Through Grade 5

NASA Astrophysics Data System (ADS)

Wade-Lyles, Terri A.

In a large urban district in Ohio, 29.2% of Grade 5, 28.7% of Grade 8, and 45.7% of Grade 10 students passed the state test in science. School district administrators formed a community partnership with local science institutions in order to provide students with hands-on place-based learning experiences intended to improve science academic achievement in PK-Grade 5. The purpose of this qualitative program evaluation was to determine the level of implementation of that place-based program by examining the efficacy of the teachers' embedded professional development and their experiences with the training components. Bruner's theory of cognitive development was used to examine teachers' needs in facilitating the program. A stratified random sample of 659 PK-Grade 5 teachers from 73 district elementary schools was selected, and 57 teachers responded to an anonymous online survey of 5 open-ended questions. Data were analyzed using thematic analysis to identity factors that enhanced or impeded the implementation of place-based education programming based on their professional development. The key findings indicated that over half of the participants viewed resources as lacking, training as limited, and planning that is too time consuming, and complicated. Participants expressed the need for clarity regarding resources and more training on how to plan for and integrate the placed-based approach. The resulting project was an executive summary and interactive workshop for program stakeholders, such as administrators, teachers, and ultimately students, who would benefit from this project by improving the place-based program.

Exploring the use of statistical process control methods to assess course changes

Vollstedt, Ann-Marie

This dissertation pertains to the field of Engineering Education. The Department of Mechanical Engineering at the University of Nevada, Reno (UNR) is hosting this dissertation under a special agreement. This study was motivated by the desire to find an improved, quantitative measure of student quality that is both convenient to use and easy to evaluate. While traditional statistical analysis tools such as ANOVA (analysis of variance) are useful, they are somewhat time consuming and are subject to error because they are based on grades, which are influenced by numerous variables, independent of student ability and effort (e.g. inflation and curving). Additionally, grades are currently the only measure of quality in most engineering courses even though most faculty agree that grades do not accurately reflect student quality. Based on a literature search, in this study, quality was defined as content knowledge, cognitive level, self efficacy, and critical thinking. Nineteen treatments were applied to a pair of freshmen classes in an effort in increase the qualities. The qualities were measured via quiz grades, essays, surveys, and online critical thinking tests. Results from the quality tests were adjusted and filtered prior to analysis. All test results were subjected to Chauvenet's criterion in order to detect and remove outlying data. In addition to removing outliers from data sets, it was felt that individual course grades needed adjustment to accommodate for the large portion of the grade that was defined by group work. A new method was developed to adjust grades within each group based on the residual of the individual grades within the group and the portion of the course grade defined by group work. It was found that the grade adjustment method agreed 78% of the time with the manual ii grade changes instructors made in 2009, and also increased the correlation between group grades and individual grades. Using these adjusted grades, Statistical Process Control (SPC) methods were employed to evaluate the impact of the treatments applied to improve the courses. It was determined that using SPC is advantageous because it does not require additional resources and is not affected if a course is curved by adding the same amount of points to each student's grade. It was also determined that SPC results, unlike average grade, correlated well with anecdotal evidence from the instructors concerning how well the students performed in any given year. In addition to application of SPC to evaluate curriculum change, statistical analysis was used to show that course grades correlate with quiz grades, but do not correlate with critical thinking, self efficacy, or cognitive level which implies that treatments need to be implemented to increase these qualities.

Replicating effective pedagogical approaches from introductory physics to improve student learning of quantum mechanics

NASA Astrophysics Data System (ADS)

Sayer, Ryan Thomas

Upper-level undergraduate students entering a quantum mechanics (QM) course are in many ways similar to students entering an introductory physics course. Numerous studies have investigated the difficulties that novices face in introductory physics as well as the pedagogical approaches that are effective in helping them overcome those difficulties. My research focuses on replicating effective approaches and instructional strategies used in introductory physics courses to help advanced students in an upper-level QM course. I have investigated the use of Just-in-time Teaching (JiTT) and peer discussion involving clicker questions in an upper-level quantum mechanics course. The JiTT approach including peer discussions was effective in helping students overcome their difficulties and improve their understanding of QM concepts. Learning tools, such as a Quantum Interactive Learning Tutorial (QuILT) based on the Doubleslit Experiment (DSE) which I helped develop, have been successful in helping upper-level undergraduate students improve their understanding of QM. Many students have also demonstrated the ability to transfer knowledge from a QuILT based on the Mach-Zehnder interferometer while working on the DSE QuILT. In addition, I have been involved in implementing research-based activities during our semester-long professional development course for teaching assistants (TAs). In one intervention, TAs were asked to grade student solutions to introductory physics problems first using their choice of method, then again using a rubric designed to promote effective problem-solving approaches, then once more at the end of the semester using their choice of method. This intervention found that many TAs have ingrained beliefs about the purposes of grading which include placing the burden of proof on the instructor as well as a belief that grading cannot serve as a formative assessment. I also compared TAs grading practices and considerations when grading student solutions to QM problems versus when grading student solutions to introductory physics. Many TAs penalized students for not explicating the problem solving process more often in the QM context than in the introductory physics context. The implications of these interventions for promoting student learning in QM are discussed.

The medial ulnar collateral ligament (UCL) is the primary static stabilizer to valgus stress of the elbow. Injuries to the UCL are common in baseball pitchers. In the 1970s, reconstructive surgery was developed. Return-to-play (RTP) rates of 67% to 95% after reconstruction have been reported. There is a paucity of published studies among professional baseball players reporting RTP with nonoperative treatment. To identify professional baseball players' ability to RTP after the nonoperative treatment of UCL injuries based on the magnetic resonance imaging (MRI) grade. Case series; Level of evidence, 4. A review of elbow injuries among a professional baseball organization from 2006 to 2011 was performed. MRI was performed on all players. Forty-three UCL injuries were diagnosed. Treatment included rehabilitation, surgery, or both. Rates of RTP and return to the same level of play or higher (RTSP) were calculated and correlated with the MRI grade, location of injury, and player position. MRI grading was as follows: I, intact ligament with or without edema; IIA, partial tear; IIB, chronic healed injury; and III, complete tear. Forty-three UCL injuries in 43 players were diagnosed. Eight had complete tears (grade III), were treated operatively with UCL reconstruction, and had an RTP rate of 75% and RTSP rate of 63% (5/8 returned to the same level and 1 to a lower level). All 8 were pitchers. The remaining 35 players had incomplete injuries (4 grade I, 8 grade IIA, and 23 grade IIB), consisting of 24 pitchers and 11 positional players. Of these 35 players, 1 underwent surgery without attempted rehabilitation, 3 initiated rehabilitation until MRI was performed and then underwent surgery, and 3 underwent surgery after failed rehabilitation. The 7 players who underwent UCL reconstruction surgery had an RTP rate of 100% and RTSP rate of 86% (6/7 returned to the same level and 1 to a lower level). The remaining 28 with nonoperative treatment had both RTP and RTSP rates of 93% (26/28 returned to the same level and 0 to a lower level). Of these, 10 were positional players with an RTSP rate of 90%, and 18 were pitchers with an RTSP rate of 94%. Of all players with incomplete UCL injuries who completed nonoperative rehabilitative treatment (n = 31), 26 had a successful RTSP (84%). Incomplete UCL injuries in professional baseball players can be successfully treated nonoperatively in the majority of cases. Pitchers are more likely to have complete tears leading to surgery. MRI grading of UCL injuries can help predict RTP and the need for surgery. © 2016 The Author(s).

Middle school science curriculum design and 8th grade student achievement in Massachusetts public schools

NASA Astrophysics Data System (ADS)

Clifford, Betsey A.

The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used teaching middle school science: integrated and discipline-based. In the proposed standards, the Massachusetts DESE uses grade-by-grade standards using an integrated approach. It was not known if there is a statistically significant difference in student achievement on the 8th grade science MCAS assessment for students taught with an integrated or discipline-based approach. The results on the 8th grade science MCAS test from six public school districts from 2010 -- 2013 were collected and analyzed. The methodology used was quantitative. Results of an ANOVA showed that there was no statistically significant difference in overall student achievement between the two curriculum models. Furthermore, there was no statistically significant difference for the various domains: Earth and Space Science, Life Science, Physical Science, and Technology/Engineering. This information is useful for districts hesitant to make the change from a discipline-based approach to an integrated approach. More research should be conducted on this topic with a larger sample size to better support the results.

Massive Open Online Courses (MOOCs) are opportunities for thousands of students to take university level courses at little to no cost. The aim of this talk is to present and analyze an often used assessment tool in MOOCs - peer grading. We collected a wealth of data on peer grading process during our session based MOOC “Astronomy: Exploring Time and Space” offered through Coursera in Spring 2015. We found that peer-grading participants are different from the general course population. Additionally, we found that peer grading participation is the single best predictor for course completion. We compared three different essay-based peer graded assignments throughout the course according to the lengths of submitted essays, time spent grading, number of essays graded by individual users, and a percentage of relevant videos watched. In all of these criteria participation in the first assignment turned out to be statistically significantly different from the other two. Finally we investigated validity and reliability of peer graders by comparing their grades with trained undergraduate graders and instructors on a subsample of 300 essays. Although we found out that validity and reliability of peer grading is limited, we were still able to show that results of peer grading strongly correlate with the final grades from the course and also invested effort in general. Therefore despite its shortcomings, peer grading still manages to identify good students and is very viable tool useful for MOOC-scale formative assessment.

Background and Objective: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2011 grading classification has been used to evaluate the severity of patients with chronic obstructive pulmonary disease (COPD). However, little is known about the relationship between the systemic inflammation and this classification. We aimed to study the relationship between serum CRP and the components of the GOLD 2011 grading classification. Methods: C-reactive protein (CRP) levels were measured in 391 clinically stable COPD patients and in 50 controls from June 2, 2015 to October 31, 2015 in the First Affiliated Hospital of Xiamen University. The association between CRP levels and the components of the GOLD 2011 grading classification were assessed. Results: Correlation was found with the following variables: GOLD 2011 group (0.240), age (0.227), pack year (0.136), forced expiratory volume in one second % predicted (FEV1%; -0.267), forced vital capacity % predicted (-0.210), number of acute exacerbations in the past year (0.265), number of hospitalized exacerbations in the past year (0.165), British medical Research Council dyspnoea scale (0.121), COPD assessment test score (CAT, 0.233). Using multivariate analysis, FEV1% and CAT score manifested the strongest negative association with CRP levels. Conclusions: CRP levels differ in COPD patients among groups A-D based on GOLD 2011 grading classification. CRP levels are associated with several important clinical variables, of which FEV1% and CAT score manifested the strongest negative correlation. PMID:28083044

Sexual communication is a principal means of transmitting sexual values, expectations, and knowledge from parents to their children and adolescents. Many parents seek information and guidance to support talking with their children about sex and sexuality. Parent education materials can deliver this guidance but must use appropriate readability levels to facilitate comprehension and motivation. This study appraised the readability of educational materials to support parent sexual communication with their children. Fifty brochures, pamphlets, and booklets were analyzed using the Flesch-Kincaid, Gunning Fog, and Simple Measure of Gobbledygook (SMOG) index methods. Mean readability grade-level scores were 8.3 (range = 4.5-12.8), 9.7 (range = 5.5-14.9), and 10.1 (range = 6.7-13.9), respectively. Informed by National Institutes of Health-recommended 6th to 7th grade levels and American Medical Association-recommended 5th to 6th grade levels, percentages falling at or below the 7.0 grade level were calculated as 38%, 12%, and 2% and those falling at or below the 6.0 grade level were calculated as 12%, 2%, and 0% based on the Flesch-Kincaid, Gunning Fog, and SMOG methods, respectively. These analyses indicate that the majority of educational materials available online to support parents' communication with their children about sex and sexuality do not meet the needs of many or most parents. Efforts to improve the accessibility of these materials are warranted.

The present study tested the possibility of operationalizing levels of knowledge acquisition based on Vygotsky’s theory of cognitive growth. An assessment tool (SAM-Math) was developed to capture a hypothesized hierarchical structure of mathematical knowledge consisting of procedural, conceptual, and functional levels. In Study 1, SAM-Math was administered to 4th-grade students (N = 2,216). The results of Rasch analysis indicated that the test provided an operational definition for the construct of mathematical competence that included the three levels of mastery corresponding to the theoretically based hierarchy of knowledge. In Study 2, SAM-Math was administered to students in 4th, 6th, 8th, and 10th grades (N = 396) to examine developmental changes in the levels of mathematics knowledge. The results showed that the mastery of mathematical concepts presented in elementary school continued to deepen beyond elementary school, as evidenced by a significant growth in conceptual and functional levels of knowledge. The findings are discussed in terms of their implications for psychological theory, test design, and educational practice. PMID:29795820

OBJECTIVE: Choices of pharmacologic therapies for pulmonary arterial hypertension (PAH) are ideally guided by high-level evidence. The objective of this guideline is to provide clinicians advice regarding pharmacologic therapy for adult patients with PAH as informed by available evidence. METHODS: This guideline was based on systematic reviews of English language evidence published between 1990 and November 2013, identified using the MEDLINE and Cochrane Library databases. The strength of available evidence was graded using the Grades of Recommendations, Assessment, Development, and Evaluation methodology. Guideline recommendations, or consensus statements when available evidence was insufficient to support recommendations, were developed using a modified Delphi technique to achieve consensus. RESULTS: Available evidence is limited in its ability to support high-level recommendations. Therefore, we drafted consensus statements to address many clinical questions regarding pharmacotherapy for patients with PAH. A total of 79 recommendations or consensus statements were adopted and graded. CONCLUSIONS: Clinical decisions regarding pharmacotherapy for PAH should be guided by high-level recommendations when sufficient evidence is available. Absent higher level evidence, consensus statements based upon available information must be used. Further studies are needed to address the gaps in available knowledge regarding optimal pharmacotherapy for PAH. PMID:24937180

Patient-reported outcome measures (PROMs) are increasingly used to quantify patients' perceptions of functional ability. The American Medical Association and NIH suggest patient materials be written at or below 6th to 8th grade reading levels, respectively, yet one recent study asserts that few PROMs comply with these recommendations, and suggests that the majority of PROMs are written at too high of a reading level for self-administered patient use. Notably, this study was limited in its use of only one readability algorithm, although there is no commonly accepted, standard readability algorithm for healthcare-related materials. Our study, using multiple readability equations and heeding equal weight to each, hopes to yield a broader, all-encompassing estimate of readability, thereby offering a more accurate assessment of the readability of orthopaedic PROMS. (1) What proportion of orthopaedic-related PROMs and orthopaedic-related portions of the NIH Patient Reported Outcomes Measurement Information System (PROMIS ® ) are written at or below the 6th and 8th grade levels? (2) Is there a correlation between the number of questions in the PROM and reading level? (3) Using systematic edits based on guidelines from the Centers for Medicare and Medicaid Services, what proportion of PROMs achieved American Medical Association and NIH-recommended reading levels? Eighty-six (86) independent, orthopaedic and general wellness PROMs, drawn from commonly referenced orthopaedic websites and prior studies, were chosen for analysis. Additionally, owing to their increasing use in orthopaedics, four relevant short forms, and 11 adult, physical health question banks from the PROMIS ® , were included for analysis. All documents were analyzed for reading grade levels using 19 unique readability algorithms. Descriptive statistics were performed using SPSS Version 22.0. The majority of the independent PROMs (64 of 86; 74%) were written at or below the 6th grade level, with 81 of 86 (94%) written at or below the 8th grade level. All item banks (11 of 11) and short forms (four of four) of the PROMIS ® were written below the 6th grade reading level. The median reading grade level of the 86 independent PROMs was 5.0 (interquartile range [IQR], 4.6-6.1). The PROMIS ® question banks had a median reading grade level of 4.1 (IQR, 3.5-4.8); the Adult Short Forms had a median reading grade level of 4.2 (IQR, 4.2-4.3) There was no correlation appreciated between the median reading grade level and the number of questions contained in a PROM (r = -0.081; p = 0.460). For PROMs above NIH-recommended levels, following edits, all (five of five) achieved NIH reading level goals and three (three of five) achieved American Medical Association goals. Editing of these PROMs improved readability by 4.3 median grade level (before, 8.9 [IQR, 8.4-9.1], after 4.6 [IQR, 4.6-6.4], difference of medians, 4.3; p = 0.008). Patient literacy has great influence on healthcare outcomes, and readability is an important consideration in all patient-directed written materials. Our study found that more than 70% of PROMs commonly used in orthopaedics, and all orthopaedic-related portions of the PROMIS ® are written at or below the most stringent recommendations (≤ 6th grade reading level), and more than 90% of independent PROMs and all PROMIS ® materials are written at or below an 8th grade level. Additionally, the use of the Centers for Medicare and Medicaid Services guidelines for editing high reading level PROMs yields satisfactory results. Fears of widely incomprehensible PROMs may be unfounded. Future research to identify the most appropriate readability algorithm for use in the healthcare sector, and revalidation of PROMs after readability-improving edits is warranted.

2015-07-01

The point of this study is to define the effect of project-based learning approach on 8th Grade secondary-school students' statistical literacy levels for data representation. To achieve this goal, a test which consists of 12 open-ended questions in accordance with the views of experts was developed. Seventy 8th grade secondary-school students, 35 in the experimental group and 35 in the control group, took this test twice, one before the application and one after the application. All the raw scores were turned into linear points by using the Winsteps 3.72 modelling program that makes the Rasch analysis and t-tests, and an ANCOVA analysis was carried out with the linear points. Depending on the findings, it was concluded that the project-based learning approach increases students' level of statistical literacy for data representation. Students' levels of statistical literacy before and after the application were shown through the obtained person-item maps.

2018-03-01

The aims of this study were to determine whether murmur intensity in adult dogs with pulmonic stenosis or subaortic stenosis reflects echocardiographic disease severity and to determine whether a six-level murmur grading scheme provides clinical advantages over a four-level scheme. In this retrospective multi-investigator study on adult dogs with pulmonic stenosis or subaortic stenosis, murmur intensity was compared to echocardiographically determined pressure gradient across the affected valve. Disease severity, based on pressure gradients, was assessed between sequential murmur grades to identify redundancy in classification. A simplified four-level murmur intensity classification scheme ('soft', 'moderate', 'loud', 'palpable') was evaluated. In total, 284 dogs (153 with pulmonic stenosis, 131 with subaortic stenosis) were included; 55 dogs had soft, 59 had moderate, 72 had loud and 98 had palpable murmurs. 95 dogs had mild stenosis, 46 had moderate stenosis, and 143 had severe stenosis. No dogs with soft murmurs of either pulmonic or subaortic stenosis had transvalvular pressure gradients greater than 50 mmHg. Dogs with loud or palpable murmurs mostly, but not always, had severe stenosis. Stenosis severity increased with increasing murmur intensity. The traditional six-level murmur grading scheme provided no additional clinical information than the four-level descriptive murmur grading scheme. A simplified descriptive four-level murmur grading scheme differentiated stenosis severity without loss of clinical information, compared to the traditional six-level scheme. Soft murmurs in dogs with pulmonic or subaortic stenosis are strongly indicative of mild lesions. Loud or palpable murmurs are strongly suggestive of severe stenosis. © 2017 British Small Animal Veterinary Association.

2011-01-01

This study aimed to systematically identify and evaluate the readability and document complexity of currently available family history tools for the general public. Three steps were undertaken to identify family history tools for evaluation: (a) Internet searches, (b) expert consultation, and (c) literature searches. Tools identified were assessed for readability using the Simple Measure of Gobbledygook (SMOG) readability formula. The complexity of documents (i.e., forms collecting family history information) was assessed using the PMOSE/IKIRSCH document readability formula. A total of 78 tools were identified, 47 of which met the criteria for inclusion. SMOG reading grade levels for multimedia-based tools ranged from 10.1 to 18.3, with an average score of 13.6. For print-based tools, SMOG ranged from 8.7 to 14.1, with an average score of 12.0. Document complexity ranged from very low complexity (level 1 proficiency) to high complexity (level 4 proficiency). The majority of tools are written at a reading grade level that is beyond the 8th grade average reading level in the United States. The lack of family history tools that are easy to read or use may compromise their potential effectiveness in identifying individuals at increased risk for chronic diseases in the general population.

The objective of this analysis is to examine how participation in different types of competitive sports (based on level of contact) during high school is associated with substance use 1 to 4 years after the 12th grade. The analysis uses nationally representative samples of 12th graders from the Monitoring the Future Study who were followed 1 to 4 years after the 12th grade. The longitudinal sample consisted of 970 12th graders from six recent cohorts (2006–2011). The analyses found that respondents who participated in at least one competitive sport during the 12th grade had greater odds of binge drinking during the past two weeks (AOR = 2.04; 95% CI = 1.43, 2.90) 1 to 4 years after the 12th grade, when compared to their peers who did not participate in sports during their 12th grade year. Moreover, respondents who participated in high-contact sports (i.e., football, ice hockey, lacrosse, and wrestling) had greater odds of binge drinking (AOR = 1.80; 95% CI = 1.18, 2.72) and engaging in marijuana use during the past 30 days (AOR = 1.81; 95% CI = 1.12, 2.93) 1 to 4 years after the 12th grade when compared to their peers who did not participate in these types of sports during their 12th grade year. Accordingly, the findings indicate important distinctions in sport participation experiences on long-term substance use risk that can help inform potential interventions among young athletes.

Grade variation on interstate highways affects the roadway geometric design, vehicle performance and driver behavior, thus possibly exerting an unexpected effect on vehicular speed. Hence, determining the internal relationship between grade and speed is important and useful for drivers, traffic regulators and other traffic participants. However, the problem with performing this research is the lack of large-scale gradient and speed data. Google Earth (GE) provides an application programming interface for extracting elevation data worldwide. The elevation dataset from GE can be easily converted to grade data. In addition, our team has collected and stored speed series data for different freeways over several years. Based on the above obtainable grade and speed datasets, we conducted research on the effect of grades on free flow speeds from two perspectives. First, the influence of grades on speed was analyzed from both quantitative and qualitative aspects. The analysis of the distributions of four typical types of speeds demonstrated a decreasing tendency as the speed increased. Steeper grades generated a more intense speed fluctuation in terms of the four types of speeds. Second, a model based on the Student's t-test was developed to evaluate the level of significant difference among speed series under neighboring grades. The Student's t-test demonstrated that adjacent grades do not significantly influence the speeds. In summary, speeds under different grades showed obviously different tendencies. The findings of this study can help transport authorities set more reasonable speed limits and improve the geometric design of interstates with grade variation constraints.

The topic of gender differences in mathematical performance has received considerable attention in the fields of education, sociology, economics and psychology. We analysed gender differences based on data from the Beijing Assessment of Educational Quality in China. A large data set of Grade 5 and Grade 8 students who took the mathematical test from 2008 to 2013 (n = 73,318) were analysed. Meta-analysis was used in this research. The findings were as follows. (1) No gender differences in mathematical achievement exist among students in Grade 5, relatively small gender differences exist in Grade 8, females scored higher than males, and variance of male students is larger than that of females in both Grade 5 and Grade 8. (2) Except for statistics and probability, gender differences in other domains in Grade 8 are significantly higher than those in Grade 5, and female students outperform males. (3) The ratio of students of both gender in Grade 5 and Grade 8 at the 95-100% percentile level shows no significant differences. However, the ratio of male students is significantly higher than that of females at the 0-5% percentile level. (4) In Grade 5, the extent to which females outperformed males in low SES group is larger than that in higher SES groups, and in Grade 8, the magnitude of gender differences in urban schools is smaller than that in rural schools. There is a small gender difference among the 8th graders, with the male disadvantage at the bottom of the distribution. And gender differences also vary across school locations. © 2017 The British Psychological Society.

Although most hospital-based studies suggest more favorable survival with tumor-infiltrating lymphocytes (TILs) present in primary melanomas, it is uncertain whether TILs provide prognostic information beyond existing melanoma staging definitions. We addressed the issue in an international population-based study of patients with single and multiple primary melanomas. On the basis of the Genes, Environment and Melanoma (GEM) study, we conducted follow-up of 2,845 patients diagnosed from 1998 to 2003 with 3,330 invasive primary melanomas centrally reviewed for TIL grade (absent, nonbrisk, or brisk). The odds of TIL grades associated with clinicopathologic features and survival by TIL grade were examined. Independent predictors (P < .05) for nonbrisk TIL grade were site, histologic subtype, and Breslow thickness, and for brisk TIL grade, they were age, site, Breslow thickness, and radial growth phase. Nonbrisk and brisk TIL grades were each associated with lower American Joint Committee on Cancer (AJCC) tumor stage compared with TIL absence (P(trend) < .001). Death as a result of melanoma was 30% less with nonbrisk TIL grade (hazard ratio [HR], 0.7; 95% CI, 0.5 to 1.0) and 50% less with brisk TIL grade (HR, 0.5; 95% CI, 0.3 to 0.9) relative to TIL absence, adjusted for age, sex, site, and AJCC tumor stage. At the population level, higher TIL grade of primary melanoma is associated with a lower risk of death as a result of melanoma independently of tumor characteristics currently used for AJCC tumor stage. We conclude that TIL grade deserves further prospective investigation to determine whether it should be included in future AJCC staging revisions.

Readability is an important consideration in assessing healthcare-related literature. In order for a source of information to be the most beneficial to patients, it should be written at a level appropriate for the audience. The National Institute of Health recommends that health literature be written at a maximum level of sixth grade. This is not uniformly found in current health literature, putting patients with lower reading levels at a disadvantage. In February 2012, healthcare-oriented education resources were retrieved from websites obtained using the Google search phrase skull base tumors. Of the first 25 consecutive, unique website hits, 18 websites were found to contain information for patients. Ten different assessment scales were utilized to assess the readability of the patient-specific web pages. Patient-oriented material found online for skull base tumors was written at a significantly higher level than the reading level of the average US patient. The average reading level of this material was found to be at a minimum of eleventh grade across all ten scales. Health related material related to skull base tumors available through the internet can be improved to reach a larger audience without sacrificing the necessary information. Revisions of this material can provide significant benefit for average patients and improve their health care.

The aim of the study is to assess the administered activity levels versus visual-based image quality using visual grading regression (VGR) including an assessment of the newly stated image criteria for whole-body bone scintigraphy. A total of 90 patients was included and grouped in three levels of administered activity: 400, 500 and 600 MBq. Six clinical image criteria regarding image quality was formulated by experienced nuclear medicine physicians. Visual grading was performed in all images, where three physicians rated the fulfilment of the image criteria on a four-step ordinal scale. The results were analysed using VGR. A count analysis was also made where the total number of counts in both views was registered. The administered activity of 600 MBq gives significantly better image quality than 400 MBq in five of six criteria (P<0·05). Comparing the administered activity of 600 MBq to 500 MBq, four criteria of six show significantly better image quality (P<0·05). The administered activity of 500 MBq gives no significantly better image quality than 400 Mbq (P<0·05). The count analysis shows that none of the three levels of administrated activity fulfil the recommendations by the EANM. There was a significant improvement in perceived image quality using an activity level of 600 MBq compared to lower activity levels in whole-body bone scintigraphy for the gamma camera equipment end set-up used in this study. This type of visual-based grading study seems to be a valuable tool and easy to implement in the clinical environment. © 2014 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Prostate cancer is a common malignancy among maturing men and the second leading cause of cancer death in USA. Histopathological grading of prostate cancer is based on tissue structural abnormalities. Gleason grading system is the gold standard and is based on the organization features of prostatic glands. Although Gleason score has contributed on cancer prognosis and on treatment planning, its accuracy is about 58%, with this percentage to be lower in GG2, GG3 and GG5 grading. On the other hand it is strongly affected by "inter- and intra observer variations", making the whole process very subjective. Therefore, there is need for the development of grading tools based on imaging and computer vision techniques for a more accurate prostate cancer prognosis. The aim of this paper is the development of a novel method for objective grading of biopsy specimen in order to support histopathological prognosis of the tumor. This new method is based on texture analysis techniques, and particularly on Gray Level Co-occurrence Matrix (GLCM) that estimates image properties related to second order statistics. Histopathological images of prostate cancer, from Gleason grade2 to Gleason grade 5, were acquired and subjected to image texture analysis. Thirteen texture characteristics were calculated from this matrix as they were proposed by Haralick. Using stepwise variable selection, a subset of four characteristics were selected and used for the description and classification of each image field. The selected characteristics profile was used for grading the specimen with the multiparameter statistical method of multiple logistic discrimination analysis. The subset of these characteristics provided 87% correct grading of the specimens. The addition of any of the remaining characteristics did not improve significantly the diagnostic ability of the method. This study demonstrated that texture analysis techniques could provide valuable grading decision support to the pathologists, concerning prostate cancer prognosis.

3D Texture Analysis in Renal Cell Carcinoma Tissue Image Grading

2014-01-01

One of the most significant processes in cancer cell and tissue image analysis is the efficient extraction of features for grading purposes. This research applied two types of three-dimensional texture analysis methods to the extraction of feature values from renal cell carcinoma tissue images, and then evaluated the validity of the methods statistically through grade classification. First, we used a confocal laser scanning microscope to obtain image slices of four grades of renal cell carcinoma, which were then reconstructed into 3D volumes. Next, we extracted quantitative values using a 3D gray level cooccurrence matrix (GLCM) and a 3D wavelet based on two types of basis functions. To evaluate their validity, we predefined 6 different statistical classifiers and applied these to the extracted feature sets. In the grade classification results, 3D Haar wavelet texture features combined with principal component analysis showed the best discrimination results. Classification using 3D wavelet texture features was significantly better than 3D GLCM, suggesting that the former has potential for use in a computer-based grading system. PMID:25371701

Cerebral white matter lesions (WMLs) are related to cognitive deficits, probably due to a disruption of frontal-subcortical circuits. We explored thalamic diffusion differences related to white matter lesions (WMLs) and their association with cognitive function in middle-aged individuals. Ninety-six participants from the Barcelona-AsIA Neuropsychology Study were included. Participants were classified into groups based on low grade and high grade of periventricular hyperintensities (PVHs) and deep white matter hyperintensities (DWMHs). Tract-Based Spatial Statistics was used to study thalamic diffusion differences between groups. Mean fractional anisotropy (FA) values in significant areas were calculated for each subject and correlated with cognitive performance. Participants with high-grade PVHs and DWMHs showed lower FA thalamic values compared to those with low-grade PVHs and DWMHs, respectively. Decreased FA thalamic values in high-grade DWMHs, but not high-grade PVH, were related to lower levels of performance in psychomotor speed, verbal fluency, and visuospatial skills. Thalamic diffusion differences are related to lower cognitive function only in participants with high-grade DWMHs. These results support the hypothesis that fronto-subcortical disruption is associated with cognitive function only in DWMHs. Copyright © 2014 Elsevier Inc. All rights reserved.

Background The relationship between hyperglycemia and prostate cancer remains controversial. According to current hypotheses, elevated serum glucose levels may lead to disease development or disease prevention. Our study examined the potential correlation between pre-operative glycemic levels of patients with prostate cancer and the grade of tumor aggressiveness. Method We studied the case files of patients with a diagnosis of prostate cancer who had received putatively curative cancer surgery at the Urology Department of the Servidores do Estado Federal Hospital (RJ/Brazil). We transcribed information related to glycemia - collected up to 3 months before the surgery - and the histopathological grade of tumor aggressiveness (Gleason score) of the surgically removed prostates. Results We analyzed 42 people who met the inclusion criteria. Based on Gleason scores, among the normoglycemic patients, we detected low, moderate, and highly aggressive neoplasias in 13%, 53%, and 36% of the cases, respectively. For the hyperglycemic group, these rates were 30%, 60%, and 10%, respectively. Normoglycemic patients had primary Gleason grade 3 in 40% of the cases and grade 4 in 60% of the cases. For the hyperglycemic patients, these rates were 90% and 10%, respectively (P < 0.05 vs. grade 3 group). Conclusion Both Gleason score and primary Gleason grade were lower in hyperglycemic patients with prostate cancer than in normoglycemic patients, suggesting a “protective action” of hyperglycemic states.

2015-01-01

Despite the public health burden of adolescent substance use, delinquency, and other problem behavior, few comprehensive models of disseminating evidence-based prevention programs to communities have demonstrated positive youth outcomes at a population level, capacity to maintain program fidelity, and sustainability. We examined whether the Communities That Care (CTC; Hawkins and Catalano 1992) model had a positive impact on risk/protective factors and academic and behavioral outcomes among adolescents in a quasi-experimental effectiveness study. We conducted a longitudinal study of CTC in Pennsylvania utilizing biannual surveillance data collected through anonymous in-school student surveys. We utilized multilevel models to examine CTC impact on change in risk/protective factors, grades, delinquency, and substance use over time. Youth in CTC communities demonstrated less growth in delinquency, but not substance use, than youth in non-CTC communities. Levels of risk factors increased more slowly, and protective factors and academic performance decreased more slowly, among CTC community grade-cohorts that were exposed to evidence-based, universal prevention programs than comparison grade cohorts. Community coalitions can affect adolescent risk and protective behaviors at a population level when evidence-based programs are utilized. CTC represents an effective model for disseminating such programs. PMID:20020209

Diet, inflammation and prediabetes-impact of quality of diet.

PubMed

Uusitupa, Matti; Schwab, Ursula

2013-10-01

Low grade inflammation has been linked to risk of type 2 diabetes and atherosclerotic vascular diseases. Obesity and, in particular, abdominal obesity increase the risk of diabetes and atherosclerotic vascular diseases. One of the mechanisms could be low grade inflammation and vascular endothelial dysfunction. Permanent weight reduction is the first line of treatment both for obese individuals at increased risk of diabetes and for newly onset type 2 diabetes. Weight reduction lowers the level of several inflammatory factors in the body while increasing the level of adiponectin. Besides weight reduction the quality of diet and physical activity also modifies low grade inflammation. Based on the literature survey and our own studies in humans, it is possible to have dietary patterns that reduce inflammatory stress in the body and improves vascular endothelial dysfunction. There is strong evidence to suggest that IL-1 Ra is a very sensitive marker of low grade inflammation in obesity and related phenotypes; however, its level is markedly lowered by weight reduction and by choosing foods that have been shown to reduce inflammatory stress in the body.

This study will evaluate alternative scheduling methods implemented in secondary level schools. Students were selected based on parent selection of programs. Traditional scheduling involves numerous academic subjects with small increments of time in each class and block scheduling focuses on fewer academic subjects and more instructional time. This study will compare office referral numbers, absence frequency, and Essential Learner Outcome (ELO) science strand scores in the 8th-grade (pretest) to the same students office referrals, absence frequency, and ELO science strand scores in the 11th-grade (posttest) between Seven Period Traditional Scheduling (SPTS) and Four Period Block Scheduling (FPBS) in the hopes that no matter what schedule students are a part of, the achievement results will be similar. (Study participants had completed both grade level ELO assessments and were continuously enrolled in one high school through their junior year.

2018-03-01

The on-treatment visit (OTV) for radiation oncology is essential for patient management. Radiation toxicities recorded during the OTV may be inconsistent because of the use of free text and the lack of treatment site-specific templates. We developed a radiation oncology toxicity recording instrument (ROTOX) in a health system electronic medical record (EMR). Our aims were to assess improvement in documentation of toxicities and to develop clinic toxicity benchmarks. A ROTOX that was based on National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0) with flow-sheet functionality was developed in the EMR. Improvement in documentation was assessed at various time intervals. High-grade toxicities (ie, grade ≥ 3 by CTCAE) by site were audited to develop benchmarks and to track nursing and physician actions taken in response to these. A random sample of OTV notes from each clinic physician before ROTOX implementation was reviewed and assigned a numerical document quality score (DQS) that was based on completeness and comprehensiveness of toxicity grading. The mean DQS improved from an initial level of 41% to 99% (of the maximum possible DQS) when resampled at 6 months post-ROTOX. This high-level DQS was maintained 3 years after ROTOX implementation at 96% of the maximum. For months 7 to 9 after implementation (during a 3-month period), toxicity grading was recorded in 4,443 OTVs for 698 unique patients; 107 episodes of high-grade toxicity were identified during this period, and toxicity-specific intervention was documented in 95%. An EMR-based ROTOX enables consistent recording of treatment toxicity. In a uniform sample of patients, local population toxicity benchmarks can be developed, and clinic response can be tracked.

To define the outcomes of arthroscopic correction of femoroacetabular impingement (FAI) based on Tönnis findings within a previously reported patient population, including a comparative analysis of Tönnis grade 0 and 1 versus grade 2 changes. Outcomes (modified Harris Hip Score [mHHS]) of a previously published study of arthroscopic correction of FAI were correlated with Tönnis grade. The inclusion criteria were the first 100 consecutive patients undergoing arthroscopic FAI correction with minimum 2-year follow-up. These procedures were performed between December 2003 and May 2006. Grades were determined independently by 2 experienced clinicians. Tönnis grades 0 and 1 were compared with Tönnis grade 2. Independent variables of sex and age were also evaluated. The average age of the entire group was 34.7 years (range, 13-76 years), with 66 male and 34 female patients. Of the patients, 17 had Tönnis grade 0, 49 had Tönnis grade 1, 29 had Tönnis grade 2, and 4 had Tönnis grade 3 (1 unknown). The average mHHS improvement for Tönnis grade 0 was 20.6 points; Tönnis grade 1, 22.2 points; Tönnis grade 2, 14.9 points; and Tönnis grade 3, 18.8 points. The improvement was statistically (P < .01) and clinically (>8 points) significant across all Tönnis grades. There was no difference (P = .077) between Tönnis grades 0 and 1 (21.8 points) versus grade 2 (14.9 points). There was no difference based on sex or age. These data support that statistically and clinically meaningful successful patient-reported outcomes (mHHS) at 2 years can be encountered even in the presence of Tönnis grade 2 radiographic features. Neither age nor sex was an indicator of poorer results within similar Tönnis grades. Level III, case-control study. Copyright © 2018 Arthroscopy Association of North America.

The severity grade is an important component of a histopathologic diagnosis in a nonclinical toxicity study that helps distinguish treatment-related effects from background findings and aids in determining adverse dose levels during hazard characterization. Severity grades should be assigned based only on the extent (i.e., amount and complexity) of the morphologic change in the examined tissue section(s) and be clearly defined in the pathology report for critical lesions impacting study interpretation. However, the level of detail provided and criteria by which severity grades are assigned can vary, which can lead to inappropriate comparisons and confusion when evaluating pathology results. To help address this issue, a Working Group of the Society of Toxicologic Pathology's Scientific and Regulatory Policy Committee was formed to provide a "points to consider" article on the assignment and application of pathology severity grades. Overall, the Working Group supports greater transparency and consistency in the reporting of grading scales and provides recommendations to improve selection of diagnoses requiring more detailed severity criteria. This information should enhance the overall understanding by toxicologic pathologists, toxicologists, and regulatory reviewers of pathology findings and thereby improve effective communication in regulatory submissions.

The report card presents available evidence on the physical activity (PA) and body weight status of Kenyan children and youth. It highlights areas where Kenya is succeeding and those in which more action is needed. Comprehensive review and analysis of available data on core indicators for Kenyan children and youth 5-17 years were conducted. The grading system used was based on a set of specific criteria and existing grading schemes from similar report cards in other countries. Of the 10 core indicators discussed, body composition was favorable (grade B) while overall PA levels, organized sport participation, and active play were assigned grades of C. Active transportation and sedentary behaviors were also favorable (grade B). Family/peers, school, governmental and nongovernmental strategies were graded C. The majority of Kenyan children and youth have healthy body composition levels and acceptable sedentary time, but are not doing as well in attaining the World Health Organization (WHO) recommendation on PA. Although Kenya seems to be doing well in most indicators compared with some developed countries, there is a need for action to address existing trends toward unhealthy lifestyles. More robust and representative data for all indicators are required.

An analysis of science instruction in the fifth-grade science classroom: Investigating activity-based instruction with student-generated discussion

NASA Astrophysics Data System (ADS)

Vowell, Julie E.

The purpose of this study was to determine the extent to which debriefing impacts the level of cognitive understanding among students in the fifth-grade science classroom. This mixed methods study involved two fifth-grade science classrooms (N = 39) in a one month exploration of rocks and minerals. Two fifth-grade science classrooms participated in a unit using identical content, but had different pedagogical orientations. The experimental class was taught using the "Do-Talk-Do-Debrief" instructional method and the control class was taught using the "Do-Talk-Do" instructional method without the "Debrief" (metacognitive component). Research for the quantitative portion of this study was conducted using a pretest-posttest control-group design. The design was used to test the hypothesized relationship between an activity-based instructional method with debriefing and students' achievement. Two intact, equivalent fifth-grade classes were randomly assigned to treatment and control conditions. Prior to the beginning of the study, a researcher-developed pretest was administered to all participants to assess the students' prior knowledge of rocks and minerals. A posttest measure was given to the participants upon conclusion of the unit to measure knowledge and understanding. Following the posttest, the participants did not receive additional instruction over rocks and minerals. A similar posttest was administered to both groups two weeks later as an added measure for retention. A t-test for independent samples was used to examine differences on the pretest between the experimental and control groups. Likewise, a t-test was used to compare the mean scores on the first posttest (achievement). A separate t-test was conducted on the second posttest (retention) and was followed by a Pearson Product Moment Correlation, conducted by group. Research for the qualitative portion of this study involved classroom observations throughout the rock and mineral unit followed by a teacher interview. Observations were made in two fifth-grade classrooms and Flanders' Categories for Interaction Analysis was used as a framework for observing the level of social interaction. The observations were transcribed and developed into a "thick" record as suggested by Dr. Phil Carspecken's stages of qualitative research. Member checking and peer debriefing techniques were employed to increase the trustworthiness of the study. The quantitative data suggested science achievement of fifth-grade science students who learned through activity-based instruction with debriefing was statistically significantly higher than the science achievement of fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the first posttest. Also, student retention as measured by fifth-grade science students who learned through activity-based instruction was statistically significantly higher than fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the second posttest. Additionally, the effect sizes for achievement and retention were very large and educationally meaningful. Activity-based instruction enhanced with debriefing resulted in a deeper construction of knowledge and retention of understanding.

Purpose Most patients with hepatocellular carcinoma (HCC) have associated chronic liver disease, the severity of which is currently assessed by the Child-Pugh (C-P) grade. In this international collaboration, we identify objective measures of liver function/dysfunction that independently influence survival in patients with HCC and then combine these into a model that could be compared with the conventional C-P grade. Patients and Methods We developed a simple model to assess liver function, based on 1,313 patients with HCC of all stages from Japan, that involved only serum bilirubin and albumin levels. We then tested the model using similar cohorts from other geographical regions (n = 5,097) and other clinical situations (patients undergoing resection [n = 525] or sorafenib treatment for advanced HCC [n = 1,132]). The specificity of the model for liver (dys)function was tested in patients with chronic liver disease but without HCC (n = 501). Results The model, the Albumin-Bilirubin (ALBI) grade, performed at least as well as the C-P grade in all geographic regions. The majority of patients with HCC had C-P grade A disease at presentation, and within this C-P grade, ALBI revealed two classes with clearly different prognoses. Its utility in patients with chronic liver disease alone supported the contention that the ALBI grade was indeed an index of liver (dys)function. Conclusion The ALBI grade offers a simple, evidence-based, objective, and discriminatory method of assessing liver function in HCC that has been extensively tested in an international setting. This new model eliminates the need for subjective variables such as ascites and encephalopathy, a requirement in the conventional C-P grade. PMID:25512453

2017-01-01

Grade variation on interstate highways affects the roadway geometric design, vehicle performance and driver behavior, thus possibly exerting an unexpected effect on vehicular speed. Hence, determining the internal relationship between grade and speed is important and useful for drivers, traffic regulators and other traffic participants. However, the problem with performing this research is the lack of large-scale gradient and speed data. Google Earth (GE) provides an application programming interface for extracting elevation data worldwide. The elevation dataset from GE can be easily converted to grade data. In addition, our team has collected and stored speed series data for different freeways over several years. Based on the above obtainable grade and speed datasets, we conducted research on the effect of grades on free flow speeds from two perspectives. First, the influence of grades on speed was analyzed from both quantitative and qualitative aspects. The analysis of the distributions of four typical types of speeds demonstrated a decreasing tendency as the speed increased. Steeper grades generated a more intense speed fluctuation in terms of the four types of speeds. Second, a model based on the Student’s t-test was developed to evaluate the level of significant difference among speed series under neighboring grades. The Student’s t-test demonstrated that adjacent grades do not significantly influence the speeds. In summary, speeds under different grades showed obviously different tendencies. The findings of this study can help transport authorities set more reasonable speed limits and improve the geometric design of interstates with grade variation constraints. PMID:28863157

Introductory Physics Gender Gaps: Pre- and Post-Studio Transition

Kohl, Patrick B.; Kuo, H. Vincent

2009-11-01

Prior work has characterized the gender gaps present in college-level introductory physics courses. Such work has also shown that research-based interactive engagement techniques can reduce or eliminate these gender gaps. In this paper, we study the gender gaps (and lack thereof) in the introductory calculus-based electricity and magnetism course at the Colorado School of Mines. We present eight semesters' worth of data, totaling 2577 students, with four semesters preceding a transition to Studio physics, and four following. We examine gender gaps in course grades, DFW (D grade, fail, or withdrawal) rates, and normalized gains on the Conceptual Survey of Electricity and Magnetism (CSEM), and consider factors such as student ACT scores and grades in prior math classes. We find little or no gap in male/female course grades and DFW rates, but substantial gaps in CSEM gains that are reduced somewhat by the transition to Studio physics.

Classification and Quality Evaluation of Tobacco Leaves Based on Image Processing and Fuzzy Comprehensive Evaluation

PubMed Central

Zhang, Fan; Zhang, Xinhong

2011-01-01

Most of classification, quality evaluation or grading of the flue-cured tobacco leaves are manually operated, which relies on the judgmental experience of experts, and inevitably limited by personal, physical and environmental factors. The classification and the quality evaluation are therefore subjective and experientially based. In this paper, an automatic classification method of tobacco leaves based on the digital image processing and the fuzzy sets theory is presented. A grading system based on image processing techniques was developed for automatically inspecting and grading flue-cured tobacco leaves. This system uses machine vision for the extraction and analysis of color, size, shape and surface texture. Fuzzy comprehensive evaluation provides a high level of confidence in decision making based on the fuzzy logic. The neural network is used to estimate and forecast the membership function of the features of tobacco leaves in the fuzzy sets. The experimental results of the two-level fuzzy comprehensive evaluation (FCE) show that the accuracy rate of classification is about 94% for the trained tobacco leaves, and the accuracy rate of the non-trained tobacco leaves is about 72%. We believe that the fuzzy comprehensive evaluation is a viable way for the automatic classification and quality evaluation of the tobacco leaves. PMID:22163744

Calorie restriction (CR) remains the most robust intervention to extend life span and improve health span. Using a global mass spectrometry-based metabolomics approach, we identified metabolites that were significantly differentially expressed in the plasma of C57BL/6 mice, fed graded levels of calorie restriction (10% CR, 20% CR, 30% CR, and 40% CR) compared with mice fed ad libitum for 12 hours a day. The differential expression of metabolites increased with the severity of CR. Pathway analysis revealed that graded CR had an impact on vitamin E and vitamin B levels, branched chain amino acids, aromatic amino acids, and fatty acid pathways. The majority of amino acids correlated positively with fat-free mass and visceral fat mass, indicating a strong relationship with body composition and vitamin E metabolites correlated with stomach and colon size, which may allude to the beneficial effects of investing in gastrointestinal organs with CR. In addition, metabolites that showed a graded effect, such as the sphinganines, carnitines, and bile acids, match our previous study on liver, which suggests not only that CR remodels the metabolome in a way that promotes energy efficiency, but also that some changes are conserved across tissues.

Misuse and diversion of prescription opioids have been critical in facilitating the opioid epidemic. Our objective was to perform a systematic evidence-based review delineating perioperative regimens (including opioid alternatives) evaluated for endoscopic sinus surgery. PubMed/MEDLINE, Cochrane Library, and EmBase databases were evaluated for studies detailing analgesics employed after endoscopic sinus surgery. Studies were assessed for level of evidence. Bias risk was evaluated using the Cochrane Bias tool and GRADE criteria. Medication, administration, adverse effects, pain scores, and rescue analgesic consumption were evaluated. A summary of evidence detailing benefits, harm, and cost was prepared. Thirty-two studies encompassing 1812 patients were included. The GRADE criteria determined the overall evidence to be of moderate quality. Perioperative acetaminophen had few adverse events and reduced immediate need for opioid rescue after sinus surgery; studies evaluating acetaminophen demonstrate a preponderance of benefit over harm. Nonsteroidal anti-inflammatory drugs (NSAIDs) also reduce postoperative opioid consumption, although a small portion of patients undergoing sinus surgery harbor the potential for NSAID intolerance. The aggregate level of evidence for studies evaluating NSAIDs was grade A, whereas the aggregate grade of evidence for several other agents was grade B. There is evidence supporting the use of NSAIDs and gabapentin for the control of pain after endoscopic sinus surgery. Acetaminophen, α-agonists, and local anesthetics are also viable options for postoperative analgesia. Familiarity with these data is essential to facilitate the use of opioid alternatives. Further large-scale, multi-institutional, randomized trials are needed to provide conclusive recommendations for these perioperative analgesics. © 2018 ARS-AAOA, LLC.

Cross-sectional analysis of online spine-related patient education materials from leading academic centers. To assess the readability levels of spine surgery-related patient education materials available on the websites of academic orthopedic surgery departments. The Internet is becoming an increasingly popular resource for patient education. Yet many previous studies have found that Internet-based orthopedic-related patient education materials from subspecialty societies are written at a level too difficult for the average American; however, no prior study has assessed the readability of spine surgery-related patient educational materials from leading academic centers. All spine surgery-related articles from the online patient education libraries of the top five US News & World Report-ranked orthopedic institutions were assessed for readability using the Flesch-Kincaid (FK) readability test. Mean readability levels of articles amongst the five academic institutions and articles were compared. We also determined the number of articles with readability levels at or below the recommended sixth- or eight-grade levels. Intraobserver and interobserver reliability of readability assessment were assessed. A total of 122 articles were reviewed. The mean overall FK grade level was 11.4; the difference in mean FK grade level between each department varied significantly (range, 9.3-13.4; P < 0.0001). Twenty-three articles (18.9%) had a readability level at or below the eighth grade level, and only one (0.8%) was at or below the sixth grade level. Intraobserver and interobserver reliability were both excellent (intraclass correlation coefficient of 1 for both). Online patient education materials related to spine from academic orthopedic centers are written at a level too high for the average patient, consistent with spine surgery-related patient education materials provided by the American Academy of Orthopaedic Surgeons and spine subspecialty societies. This study highlights the potential difficulties patients might have in reading and comprehending the information in publicly available education materials related to spine. N/A.

A population-based cross-sectional multiregion postal survey. To provide a descriptive epidemiology of the prevalence and severity of back pain in German adults and to analyze sociodemographic correlates for disabling back pain within and across regions. Back pain is a leading health problem in Germany. However, comprehensive population-based evidence on the severity of back pain is still fragmentary for this country. Despite earlier findings concerning large prevalence differences across regions, systematic explanations remain to be ascertained. Questionnaire data were collected for 9263 subjects in 5 German cities and regions (population-based random samples, postal questionnaire). Point, 1-year, and lifetime prevalence were assessed using direct questions, and graded back pain was determined using the Graded Chronic Pain Scale. Poststratification was applied to adjust for cross-regional sociodemographic differences. Point-prevalence was 37.1%, 1-year prevalence 76.0%, and lifetime prevalence 85.5%. A substantial minority had severe (Grade II, 8.0%) or disabling back pain (Grade III-IV, 11.2%). Subjects with a low educational level reported substantially more disabling back pain. This variable was an important predictor for large cross-regional differences in the burden of back pain. Back pain is a highly prevalent condition in Germany. Disabling back pain in this country may be regarded as part of a social disadvantage syndrome. Educational level should receive greater attention in future cross-regional comparisons of back pain.

To determine the predictive validity of the U.S. Evidence-based Practice Center (EPC) approach to GRADE (Grading of Recommendations Assessment, Development and Evaluation). Based on Cochrane reports with outcomes graded as high quality of evidence (QOE), we prepared 160 documents which represented different levels of QOE. Professional systematic reviewers dually graded the QOE. For each document, we determined whether estimates were concordant with high QOE estimates of the Cochrane reports. We compared the observed proportion of concordant estimates with the expected proportion from an international survey. To determine the predictive validity, we used the Hosmer-Lemeshow test to assess calibration and the C (concordance) index to assess discrimination. The predictive validity of the EPC approach to GRADE was limited. Estimates graded as high QOE were less likely, estimates graded as low or insufficient QOE more likely to remain stable than expected. The EPC approach to GRADE could not reliably predict the likelihood that individual bodies of evidence remain stable as new evidence becomes available. C-indices ranged between 0.56 (95% CI, 0.47 to 0.66) and 0.58 (95% CI, 0.50 to 0.67) indicating a low discriminatory ability. The limited predictive validity of the EPC approach to GRADE seems to reflect a mismatch between expected and observed changes in treatment effects as bodies of evidence advance from insufficient to high QOE.

An improved ability to quantify differences in the fabrication yields of beef carcasses would facilitate the application of value-based marketing. This study was conducted to evaluate the ability of the Dual-Component Australian VIASCAN to 1) predict fabricated beef subprimal yields as a percentage of carcass weight at each of three fat-trim levels and 2) augment USDA yield grading, thereby improving accuracy of grade placement. Steer and heifer carcasses (n = 240) were evaluated using VIASCAN, as well as by USDA expert and online graders, before fabrication of carcasses to each of three fat-trim levels. Expert yield grade (YG), online YG, VIASCAN estimates, and VIASCAN estimated ribeye area used to augment actual and expert grader estimates of the remaining YG factors (adjusted fat thickness, percentage of kidney-pelvic-heart fat, and hot carcass weight), respectively, 1) accounted for 51, 37, 46, and 55% of the variation in fabricated yields of commodity-trimmed subprimals, 2) accounted for 74, 54, 66, and 75% of the variation in fabricated yields of closely trimmed subprimals, and 3) accounted for 74, 54, 71, and 75% of the variation in fabricated yields of very closely trimmed subprimals. The VIASCAN system predicted fabrication yields more accurately than current online yield grading and, when certain VIASCAN-measured traits were combined with some USDA yield grade factors in an augmentation system, the accuracy of cutability prediction was improved, at packing plant line speeds, to a level matching that of expert graders applying grades at a comfortable rate.

Feasibility study of direct spectra measurements of Thomson scattered photons for fusion-grade plasmas is performed based on a forward model of the KSTAR Thomson scattering system. Expected spectra in the forward model are calculated based on Selden function including the relativistic polarization correction. Noise in the signal is modeled with photon noise and Gaussian electrical noise. Electron temperature and density are inferred using Bayesian probability theory. Based on bias error, full width at half maximum and entropy of posterior distributions, spectral measurements are found to be feasible. Comparisons between spectrometer-based and polychromator-based Thomson scattering systems are performed with varying quantum efficiency and electrical noise levels.

In this study, students and their teachers participated in a layered approach to reading intervention in kindergarten through third grade that included professional development for teachers in scientifically based reading instruction, ongoing measurement of reading progress, and additional small-group or individual instruction for students whose progress was insufficient to maintain grade-level reading achievement. Reading outcomes were compared with historical control groups of students in the same schools. The findings revealed overall improvements in reading, improved reading for students who began the study in high-risk categories, and decreases in the incidence of reading disability at the end of third grade. Implications for scaling up are discussed.

The winter reproductive areas of Puccinia striiformis var. striiformis in Sichuan Basin are often the places mostly affected by wheat stripe rust. With data on the meteorological condition and stripe rust situation at typical stations in the winter reproductive area in Sichuan Basin from 1999 to 2016, this paper classified the meteorological conditions inducing wheat stripe rust into 5 grades, based on the incidence area ratio of the disease. The meteorological factors which were biologically related to wheat stripe rust were determined through multiple analytical methods, and a meteorological grade model for forecasting wheat stripe rust was created. The result showed that wheat stripe rust in Sichuan Basin was significantly correlated with many meteorological factors, such as the ave-rage (maximum and minimum) temperature, precipitation and its anomaly percentage, relative humidity and its anomaly percentage, average wind speed and sunshine duration. Among these, the average temperature and the anomaly percentage of relative humidity were the determining factors. According to a historical retrospective test, the accuracy of the forecast based on the model was 64% for samples in the county-level test, and 89% for samples in the municipal-level test. In a meteorological grade forecast of wheat stripe rust in the winter reproductive areas in Sichuan Basin in 2017, the prediction was accurate for 62.8% of the samples, with 27.9% error by one grade and only 9.3% error by two or more grades. As a result, the model could deliver satisfactory forecast results, and predicate future wheat stripe rust from a meteorological point of view.

Abstract Background: Urban elementary schools in minority communities with high obesity prevalence may have limited resources for physical education (PE) to achieve daily activity recommendations. Little is known whether integrating physical activity (PA) into classrooms can increase activity levels of students attending such schools. Methods: We conducted a cluster randomized, controlled trial among kindergarten and first-grade students from four Bronx, New York, schools to determine feasibility and impact of a classroom-based intervention on students' PA levels. Students in two intervention schools received the Children's Hospital at Montefiore Joining Academics and Movement (CHAM JAM), an audio CD consisting of 10-minute, education-focused aerobic activities led by teachers three times a day. PA was objectively measured by pedometer. Each subject wore a sealed pedometer during the 6-hour school day for 5 consecutive days at baseline (Time 1) and 8 weeks postintervention (Time 2). Hierarchical linear models were fit to evaluate differences in mean number of steps between the two groups. Results: A total of 988 students participated (intervention group, n=500; control group, n=488). There was no significant difference at baseline between the two groups on mean number of steps (2581 [standard deviation (SD), 1284] vs. 2476 [SD, 1180]; P=0.71). Eight weeks post–CHAM JAM, intervention group students took significantly greater mean number of steps than controls (2839 [SD, 1262] vs. 2545 [SD, 1153]; P=0.0048) after adjusting for baseline number of steps and other covariates (grade, gender, recess, and PE class). CHAM JAM was equally effective in gender, grade level, and BMI subgroups. Conclusions: CHAM JAM significantly increased school-based PA among kindergarten and first-grade students in inner-city schools. This approach holds promise as a cost-effective means to integrate the physical and cognitive benefits of PA into high-risk schools. PMID:25747719

1 in 7 men receive a diagnosis of prostate cancer in their lifetime. The aggressiveness of the treatment plan adopted by the patient is strongly influenced by Gleason grade. Gleason grade is determined by the pathologist based on the level of glandular formation and complexity seen in the patient's biopsy. However, studies have shown that the disagreement rate between pathologists on Gleason grades 3 and 4 is high and this affects treatment options. We used quantitative phase imaging to develop an objective method for Gleason grading. Using the glandular solidity, which is the ratio of the area of the gland to a convex hull fit around it, and anisotropy of light scattered from the stroma immediately adjoining the gland, we were able to quantitatively separate Gleason grades 3 and 4 with 81% accuracy in 43 cases marked as difficult by pathologists.

Malignant astrocytoma is the most commonly occurring brain tumor in humans. Oxidative stress is implicated in the development of cancers. Superoxide dismutase 2 (SOD2) was found to exert tumor suppressive effect in basic research, but increased SOD2 protein level was associated with higher aggressiveness of human astrocytomas. However, studies reporting alterations of antioxidant enzymes in human astrocytomas often employed less accurate methods or included different types of tumors. Here we analyzed the mRNA levels, activities, and protein levels of primary antioxidant enzymes in control brain tissues and various grades of astrocytomas obtained from 40 patients. SOD1 expression, SOD1 activity, and SOD1 protein level were lower in Grade IV astrocytomas. SOD2 expression was lower in low-grade (Grades I and II) and Grade III astrocytomas than in controls, but SOD2 expression and SOD2 protein level were higher in Grade IV astrocytomas than in Grade III astrocytomas. Although there was no change in SOD2 activity and a lower activity of citrate synthase (CS), the MnSOD:CS ratio increased in Grade IV astrocytomas compared with controls and low-grade astrocytomas. Furthermore, SOD1 activity, CS activity, SOD1 expression, GPX4 expression, and GPX4 protein level were inversely correlated with the malignancy, whereas catalase activity, catalase protein, SOD2 protein level, and the SOD2:CS ratio were positively correlated with the degree of malignancy. Lower SOD2:CS ratio was associated with poor outcomes for Grade IV astrocytomas. This is the first study to quantify changes of various primary antioxidant enzymes in different grades of astrocytomas at different levels concurrently in human astrocytomas.

Clinical practice guidelines hope to offer unbiased, evidence-based guidance for clinicians. This paper examines levels of evidence contained within the guidelines of the Society of Obstetricians and Gynaecologists of Canada and compares classification of the recommendation (CoR) A/B/C/D/E/L (derived from evidence and consensus) versus quality of evidence assessment (QoEA) I-III. 1250 recommendations were analysed and 43% of recommendations were graded as "good" evidence, the highest grade of CoR, while just 24.6% of recommendations were based on the highest level of QoEA (level I). The paper discusses possible reasons for this discrepancy. The authors hope that this analysis promotes greater transparency in evidence-based medicine ultimately leading to using the best quality of evidence available yet taking into account any areas of scientific uncertainty. This will enhance respectful care of patients, while taking into account their autonomy and furthering the cause of patient centre care.

A xenobank of patient-derived (PDX) ovarian tumor samples has been established consisting of tumors with different sensitivity to cisplatin (DDP), from very responsive to resistant. As the DNA repair pathway is an important driver in tumor response to DDP, we analyzed the mRNA expression of 20 genes involved in the nucleotide excision repair, fanconi anemia, homologous recombination, base excision repair, mismatch repair and translesion repair pathways and the methylation patterns of some of these genes. We also investigated the correlation with the response to platinum-based therapy. The mRNA levels of the selected genes were evaluated by Real Time-PCR (RT-PCR) with ad hoc validated primers and gene promoter methylation by pyrosequencing. All the DNA repair genes were variably expressed in all 42 PDX samples analyzed, with no particular histotype-specific pattern of expression. In high-grade serous/endometrioid PDXs, the CDK12 mRNA expression levels positively correlated with the expression of TP53BP1, PALB2, XPF and POLB. High-grade serous/endometrioid PDXs with TP53 mutations had significantly higher levels of POLQ, FANCD2, RAD51 and POLB than high-grade TP53 wild type PDXs. The mRNA levels of CDK12, PALB2 and XPF inversely associated with the in vivo DDP antitumor activity; higher CDK12 mRNA levels were associated with a higher recurrence rate in ovarian patients with low residual tumor. These data support the important role of CDK12 in the response to a platinum based therapy in ovarian patients. PMID:29872499

To determine if physical activity (PA) during the school day varied by school, grade level, gender, weight status, and physical education (PE) and recess participation among urban kindergarten and first-grade students. Cross-sectional study at 4 Bronx, NY, schools. Student PA was measured by a Yamax Digi-Walker pedometer, an objective and validated measure of PA in children. Each student wore a sealed pedometer during school for 5 consecutive days. Hierarchical models were fit to identify variables predictive of PA. A total of 916 had valid pedometer data (53% male, 70% Hispanic, mean age 5.98 years [SD 0.66], 45% overweight). PA varied by school (P < .0001). First-grade students took a significantly greater mean number of steps during school than kindergarten students. Overall, students took an average of 2479.7 (SD 961.8) steps/school day. PA did not differ by BMI status. Students took on average 724 more steps on PE days than on non-PE days and 490 more steps on days with outdoor recess than nonrecess days (P < .05 for both). Fewer than 1% of all students achieved lower cut points for previously published mean range of steps/school day for boys and girls. Multivariable analysis revealed higher grade level, participation in PE class, and outdoor recess as independent predictors of PA. PA levels were low in kindergarten and first-grade students. Future interventions incorporating classroom-based PA and outdoor recess may increase PA in resource-poor urban schools with limited PE facilities.

Using inquiry-based instructional strategies in third-grade science

Harris, Fanicia D.

The purpose of the study was to determine if the use of inquiry-based instructional strategies as compared to traditional instructional strategies would increase third-grade students' achievement in science, based on the pretest/posttest of the school system and the Georgia Criterion-Referenced Competency Test (CRCT). Inquiry-based instruction, presented students with a question, an observation, a data set, or a hypothesis for problem solving such as scientists use when working in real-world situations. This descriptive research employed a quantitative strategy using a pretest/posttest control group design. The research compared the science academic achievement levels of one Grade 3 class [N=14] exposed to a teacher's inquiry-based instructional strategies as compared to one Grade 3 class [ N=18] exposed to a teacher's traditional instructional strategies. The study compared the science academic performance levels of third-grade students as measured by pretest/posttest mean scores from the school system-based assessment and the Georgia CRCT. Four research hypotheses were examined. Based on the overall findings from this study, both the experimental group and the control group significantly increased their mean scores from the pretests to the posttests. The amount of gain from the pretest to the posttest was significantly greater for the experimental group than the control group for pretest/posttest 1 [t(12) = 8.79, p < .01] and pretest/posttest 2 [t(12) = 9.40, p < .01]. The experimental group significantly outperformed the control group with regard to their mean number of items answered correctly on the life sciences test [t(27) = -1.95, p = .06]. Finally, the control group did not outperform the experimental group on any of the comparisons made throughout this study. The results of this study provide empirical support for the effectiveness of the use of inquiry-based learning strategies, given that the experimental group outperformed the control group on all four posttests, on the science CRCT and on the individual Science portions on the test including earth, life and physical sciences. In fact, this study was able to detect significant differences between the experimental group and the control group with regard to the degree to which the students improved from the pretests to the posttests.

Informed consents are important aids in helping patients make optimal decisions. Little knowledge exists about the quality of dental informed consents. Fifty-two informed consents used throughout the University of Texas Health Science Center at Houston Dental Branch were evaluated based on the quality of their content, readability, and presentation. Content quality was judged on four basic elements: description of procedure, risk, benefits, and alternatives. Of the clinical consents, 26 percent of forms contained all four of the basic content elements, 48 percent contained three of four elements, 16 percent contained two of four elements, and 10 percent contained one of four elements. Presentation quality was judged on twelve criteria items. The average clinical consent included seven out of twelve presentation items, and the average nonclinical consent included eight out of twelve items. Readability was judged using three standard instruments for rating readability: Flesch Reading Ease, Flesch-Kincaid Grade-Level, and Simple Measure of Gobbledygook (SMOG) grading. Average Flesch-Kincaid Grade-Level was 12.7 (range, 7.4 to 19.1), significantly higher than the recommended ninth grade level (p<.001). The results suggest that many existing dental informed consents may be improved by 1) increasing the comprehensiveness of the content, 2) improving the design and layout, and 3) reducing the readability levels for patient comprehension.

This research deals with designing learning continuum for developing a curriculum. The objective of this study is to gather the opinion of public junior and high school teachers about Learning Continuum based on Student's Level of Competence and Specific Pedagogical Material on Anatomical Aspects. This is a survey research. The population of the research is natural science teachers at junior high school and biology teacher at senior high school in Yogyakarta Special Region. Data were collected using a questionnaire. Data were analyzed using a descriptive analysis technique. Based on the results of the survey, the teachers opinion are in accordance with the level of the students they teach. Junior high school teachers argued that anatomical aspects were taught in grade VII,VIII, IX and X on the level of C2 (understanding), the high school teacher argued that anatomical aspects were taught in grade VIII, X and XI on the level of C2 (understanding) and C3 (apply). While according to the opinions of primary school teachers about aspects of anatomy resulted from the research of Subali (2016), anatomy is mostly not taught at the elementary school level, only some of the materials that are taught in this school level. Therefore, the results of the survey can be inferred that the opinions of teachers is still based on the existing curriculum.

The aim of this study is to investigate the accuracy of serum matrix metalloproteinase (MMP) levels in an effort to find a reliable factor that may play an important role in pathogenesis of hemorrhoidal disease. Twenty control subjects and 21 Grade I, 19 Grade II, 20 Grade III, and 21 Grade IV patients with internal hemorrhoid were included in this prospective study. The mean ages of control subjects were 47.65 ± 6.71 standard deviation (SD) years (range, 37 to 60 years). The mean age of internal Grade I, Grade II, Grade III, and Grade IV patients with internal hemorrhoid were 48.85 ± 6.44, 47.20 ± 6.75, 44.90 ± 6.13, and 42.95 ± 3.49 SD years (ranges, 38 to 58, 38 to 60, 34 to 55, and 38 to 50 years), respectively. Ten milliliters of blood was taken from all subjects. Enzyme-linked immunosorbent assay (ELISA) for MMP-1, -2, -7, and -9 levels were performed using an ELISA kit (R&D Systems) following the manufacturer's instructions. There was an important difference between Grade I and Grade II groups in the serum levels of MMP-9 (P < 0.01). Patients with Grade III hemorrhoidal disease had significantly higher serum levels of all MMP than patients with Grade I and Grade II hemorrhoidal disease (P < 0.001). Also, patients with Grade 4 hemorrhoidal disease had higher serum levels of MMP-7 and -9 according to Grade I, II, and III groups (P < 0.01, 0.001). High serum levels of MMP are present in patients with hemorrhoids, suggesting the possible mechanism in the pathogenesis of hemorrhoids.

Advancing health literacy has the potential to improve patient outcomes. The American Academy of Orthopaedic Surgeons' (AAOS) online patient education materials serve as a tool to improve health literacy for orthopaedic patients; however, it is unknown whether the materials currently meet the National Institutes of Health/American Medical Association's recommended sixth grade readability guidelines for health information or the mean US adult reading level of eighth grade. The purposes of this study were (1) to evaluate the mean grade level readability of online AAOS patient education materials; and (2) to determine what proportion of the online materials exceeded recommended (sixth grade) and mean US (eighth grade) reading level. Reading grade levels for 99.6% (260 of 261) of the online patient education entries from the AAOS were analyzed using the Flesch-Kincaid formula built into Microsoft Word software. Mean grade level readability of the AAOS patient education materials was 9.2 (SD ± 1.6). Two hundred fifty-one of the 260 articles (97%) had a readability score above the sixth grade level. The readability of the AAOS articles exceeded the sixth grade level by an average of 3.2 grade levels. Of the 260 articles, 210 (81%) had a readability score above the eighth grade level, which is the average reading level of US adults. Most of the online patient education materials from the AAOS had readability levels that are far too advanced for many patients to comprehend. Efforts to adjust the readability of online education materials to the needs of the audience may improve the health literacy of orthopaedic patients. Patient education materials can be made more comprehensible through use of simpler terms, shorter sentences, and the addition of pictures. More broadly, all health websites, not just those of the AAOS, should aspire to be comprehensible to the typical reader.

Structured literature review. The Scoliosis Research Society (SRS) requested an assessment of the current state of peer-reviewed evidence regarding pediatric lumbar spondylolisthesis with the goal of identifying what is known and what gaps remain in further understanding the diagnostic methods for pediatric spondylolisthesis. Spondylolisthesis in the lumbar spine is common among children and adolescents and no formal synthesis of the published literature regarding diagnostic methods has been previously performed. A comprehensive literature search was performed. Abstracts were reviewed and data from included studies were analyzed by the committee. From 6600 initial citations with abstract, 663 articles underwent full-text review. The best available evidence for the clinical questions regarding diagnostic methods was provided by 26 included studies. Six of the studies were graded as Level III (retrospective comparative), and represent the current best available evidence whereas 20 of the studies were graded as Level IV (retrospective case series) evidence. No Level V (expert opinion) studies were included in the final list. None of the studies were graded as Level I or Level II. Plain radiography is the workhorse imaging modality for diagnosing spondylolisthesis. No association between radiologic grade of spondylolisthesis and clinical presentation were noted; however, grade III and IV slips more often required surgery, and increasing slip angles were associated with worse baseline outcome scores. There is Level III evidence that the Meyerding grade appears to be more accurate for measuring slip percentage whereas the Lonstein Slip angle and Dubousset Lumbosacral Kyphosis angles are the best for measuring lumbosacral kyphosis in spondylolisthesis. In addition, higher sacral table index, pelvic incidence, sacral slope, and lower sacral table angle were associated with spondylolisthesis. True incidence could not be determined by the current literature available. However, studies in adolescent athletes demonstrated an incidence of 6% to 7% across studies. The current "best available" evidence to guide the diagnosis and characterization of pediatric spondylolisthesis is presented. Future studies are needed to provide more high-quality evidence to answer these clinically relevant questions. Level III, review of Level III studies. Copyright © 2017 Scoliosis Research Society.

Raman spectroscopy for grading of live osteosarcoma cells.

Chiang, Yi-Hung; Wu, Stewart H; Kuo, Yi-Chun; Chen, How-Foo; Chiou, Arthur; Lee, Oscar K

2015-04-18

Osteosarcoma is the most common primary malignant bone tumor, and the grading of osteosarcoma cells relies on traditional histopathology and molecular biology methods, which require RNA extraction, protein isolation and immunohistological staining. All these methods require cell isolation, lysis or fixation, which is time-consuming and requires certain amount of tumor specimen. In this study, we report the use of Raman spectroscopy for grading of malignant osteosarcoma cells. We demonstrate that, based on the detection of differential production of mineral species, Raman spectroscopy can be used as a live cell analyzer to accurately assess the grades of osteosarcoma cells by evaluating their mineralization levels. Mineralization level was assessed by measuring amount of hydroxyapatite (HA), which is highly expressed in mature osteoblasts, but not in poorly differentiated osteosarcoma cell or mesenchymal stem cells, the putative cell-of-origin of osteosarcoma. We found that under Raman spectroscopy, the level of HA production was high in MG-63 cells, which are low-grade. Moreover, hydroxyapatite production was low in high-grade osteosarcoma cells such as 143B and SaOS2 cells (p < 0.05). Matrix metalloproteinase MMP2, MMP9 were highly expressed in SaOS2, 143B and MSCs and decreased in human fetal osteoblast (FOB) and MG-63 cells as expected (p < 0.05). These results may highlight the inverse correlation between HA level and prognosis of osteosarcoma. The use of Raman spectroscopy for the measurement of HA production by the protocol reported in this study may serve as a useful tool to rapidly and accurately assess the degree of malignancy in osteosarcoma cells in a label-free manner. Such application may shorten the period of pathological diagnosis and may benefit patients who are inflicted with osteosarcoma.

We investigate the electrical conductivity of GaAs-based tunnel junctions enhanced with semimetallic ErAs nanoparticles. In particular, we examine the effects of digitally-graded InGaAs alloys on the n-type side of the tunnel junction, along with different p-type doping levels. Device characteristics of the graded structures indicate that the n-type Schottky barrier may not be the limiting factor in the tunneling current as initially hypothesized. Moreover, significantly improved forward and reverse bias tunneling currents were observed with increased p-type doping, suggesting p-side limitation.

This study examined whether the significant intervention effects of the Communities That Care (CTC) prevention system on youth problem behaviors observed in a panel of eighth-grade students (Hawkins et al. Archives of Pediatrics and Adolescent Medicine 163:789–798 2009) were mediated by community-level prevention system constructs posited in the CTC theory of change. Potential prevention system constructs included the community’s degree of (a) adoption of a science-based approach to prevention, (b) collaboration on prevention activities, (c) support for prevention, and (d) norms against adolescent drug use as reported by key community leaders in 24 communities. Higher levels of community adoption of a science-based approach to prevention and support for prevention in 2004 predicted significantly lower levels of youth problem behaviors in 2007, and higher levels of community norms against adolescent drug use predicted lower levels of youth drug use in 2007. Effects of the CTC intervention on youth problem behaviors by the end of eighth grade were mediated fully by community adoption of a science-based approach to prevention. No other significant mediated effects were found. Results support CTC’s theory of change that encourages communities to adopt a science- based approach to prevention as a primary mechanism for improving youth outcomes. PMID:23828448

According to the american medical association (AMA) and the national institutes of health (NIH), the recommended readability of patient education materials should be no greater than a sixth-grade reading level. The online patient education information produced by the american academy of orthopaedic surgeons (AAOS) may be too complicated for some patients to understand. This study evaluated whether the AAOS's online trauma-related patient education materials meet recommended readability guidelines for medical information. Ninety-nine articles from the "Broken Bones and Injuries" section of the AAOS-produced patient education website, orthoinfo.org, were analyzed for grade level readability using the Flesch-Kincaid formula, a widely-used and validated tool to evaluate the text reading level. Results for each webpage were compared to the AMA/NIH recommended sixth-grade reading level and the average reading level of U.S. adults (eighth-grade). The mean (SD) grade level readability for all patient education articles was 8.8 (1.1). All but three of the articles had a readability score above the sixth-grade level. The readability of the articles exceeded this level by an average of 2.8 grade levels (95% confidence interval, 2.6 - 3.0; P < 0.0001). Furthermore, the average readability of the articles exceeded the average reading skill level of U.S. adults (eighth grade) by nearly an entire grade level (95% confidence interval, 0.6-1.0; P < 0.0001). The majority of the trauma-related articles from the AAOS patient education website have readability levels that may make comprehension difficult for a substantial portion of the patient population.

Aim We evaluated the level of evidence of speech, language, and communication interventions for infants at high-risk for, or with a diagnosis of, cerebral palsy (CP) from 0 to 2 years old. Method We performed a systematic review of relevant terms. Articles were evaluated based on the level of methodological quality and evidence according to A Measurement Tool to Assess Systematic Reviews (AMSTAR) and Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines. Results The search terms provided 17 publications consisting of speech or language interventions. There were no interventions in the high level of evidence category. The overall level of evidence was very low. Promising interventions included Responsivity and Prelinguistic Milieu Teaching and other parent–infant transaction frameworks. Interpretation There are few evidence-based interventions addressing speech, language, and communication needs of infants and toddlers at high risk for CP, and none for infants diagnosed with CP. Recommendation guidelines include parent–infant transaction programs. PMID:27897320

Fourth and eighth grade students' conceptions of energy flow through ecosystems

NASA Astrophysics Data System (ADS)

Arkwright, Ashlie Beals

This mixed methods status study examined 32 fourth grade students' conceptual understandings of energy flow through ecosystems prior to instruction and 40 eighth grade students' conceptual understandings of the same topic after five years of daily standards-based instruction in science. Specific ecological concepts assessed related to: 1) roles of organisms; 2) the sun as the original energy source for most ecosystems; and 3) interdependency of organisms. Fourth and eighth grade students were assessed using the same three-tiered forced-choice instrument, with accompanying tasks for students to defend their forced-choice selections and rate their level of confidence in making the selections. The instrument was developed for the study by a team of researchers and was based on similar tasks presented in the research literature. Distractor options were embedded in each assessment task using common non-scientific ideas also reported in the research literature. Cronbach's alpha values at or greater than .992 for each task indicated interrater consistency of task answers, and Rasch analysis was employed to establish the reliability of the instrument. Qualitative and quantitative analyses were employed to assess the data. Constant comparative methods were employed to analyze students' written responses, which were coded and grouped into emerging themes. These themes were further developed to characterize students' conceptual understandings. Student open responses also were scored and coded by a team of researchers using a rubric to identify level of scientific understanding. Quantitative analyses included Rasch analysis used to normalize survey data. Independent samples t-tests were then employed to compare students' forced-choice responses to their written responses and to the confidence ratings, as well as to compare fourth and eighth grade students' responses. Findings indicated that eighth grade students generally outperformed the fourth grade on both the forced-choice and written responses, but both groups demonstrated conceptual difficulties in all three topics assessed. Thus, results from the current study support the assertion that students' understanding of concepts related to energy flow in ecosystems is not at the expected level according to national science education standards and frameworks. Conceptual difficulties identified in the study are discussed along with implications and curricular recommendations.

There are many factors which affect intelligence as well as physical growth of children, although genetic factor plays a prime role but social, environmental and psychological factors influence significantly the physical growth and intelligence of the child and the same can be improved through intervention. Community based studies are therefore useful to understand effect of these factors for future planning. The present study was therefore undertaken in Burdwan district of West Bengal with the objectives of studying level of intelligence of children of 3 to 6 years age group and impact of the factors related to the level of intelligence of these children. 72 children of 3 to 6 years age group were studied, of which 2/3 were either normal or having Grade-I undernutrition and the rest were either Grade-II or Grade-III. A significant positive association was found between DST IQ score (Bharat Raj) and the nutritional grade. Non-formal education also was found to have significant bearing on the IQ level. No significant relationship was however found between DST IQ score and the religion indicating culture independence of the scoring system.

To validate the conventional Japanese grading of liver metastasis for no residual tumor resection in Stage IV colorectal cancer (CRC) with liver metastasis and to identify risk factors for postoperative recurrence. The subjects of this study were 1792 Stage IV CRC patients with liver metastasis. In 1792 cases, including unresectable cases, there was a significantly different prognosis by grade (P < 0.0001). In 421 R0 cases, there was no significant difference between Grade A and Grade B (P = 0.8527). In 381 cases without extra-hepatic metastasis, the prognosis was not significantly different among three grades. On multivariate analysis, carcinoembryonic antigen within 3 months from R0 operation (3M-CEA) was an independent risk factor regardless of extrahepatic metastasis. There was a significantly different prognosis (P < 0.0001) among Grade A', defined as a normal 3M-CEA level, Grade B', defined as Grade A or B and an abnormal 3M-CEA level, and Grade C', defined as Grade C and an abnormal 3M-CEA level. The postoperative CEA level is an important risk factor during follow-up after curative resection in patients with liver metastatic colorectal carcinoma. The combination of the 3M-CEA level and conventional grading of liver metastasis is useful for follow-up of R0 resection cases.

The National Institutes of Health recommend a readability grade level of less than 7th grade for patient directed information. In this study, we use validated readability metrics to analyze patient information from prominent websites pertaining to ulcerative colitis and Crohn's disease. The terms "Crohn's Disease," "Ulcerative Colitis," and "Inflammatory Bowel Disease" were queried on Google and Bing. Websites containing patient education material were saved as a text file and then modified through expungement of medical terminology that was described within the text. Modified text was then divided into subsections that were analyzed using six validated readability scales. None of the websites analyzed in this study achieved an estimated reading grade level below the recommended 7th grade. The median readability grade level (after modification) was 11.5 grade levels for both Crohn's disease and ulcerative colitis. The treatment subsection required the highest level of education with a median readability grade of 12th grade (range of 6.9 to 17). Readability of online patient education material from the analyzed popular websites far exceeds the recommended level of being less than 7th grade. Patient education resources should be revised to achieve wider health literacy.

School-based dental programs target high-risk communities and reduce barriers to obtaining dental services by delivering care to students in their schools. We describe the evaluation of a school-based dental program operating in Chelsea, a city north of Boston, with a low-income and largely minority population, by comparing participants' oral health to a Massachusetts oral health assessment. Standardized dental screenings were conducted for students in kindergarten, third, and sixth grades. Outcomes were compared in bivariate analysis, stratified by grade and income levels. A greater percentage of Chelsea students had untreated decay and severe treatment need than students statewide. Yet, fewer Chelsea third graders had severe treatment need, and more had dental sealants. There was no significant difference in the percentage of Chelsea students having severe treatment need or dental sealants by income level. Students participating in our program do not have lower decay levels than students statewide. However, they do have lower levels of severe treatment need, likely due to treatment referrals. Our results confirm that school-based prevention programs can lead to increased prevalence of dental sealants among high-risk populations. Results provide support for the establishment of full-service school-based programs in similar communities. © 2017, American School Health Association.

Hierarchy of evidence: a simple system for orthopaedic research?

To be able to make a sound recommendation for a treatment based on the best available evidence, it is necessary to follow specific steps in acquiring literature, appraising the study design and quality, and assessing the results. Evidence-based medicine is founded on the concepts of using best evidence, levels of evidence, and grades of recommendation, and aims to provide clinicians with standardized rules to help them appraise the validity of published research. A number of systems have been developed to categorize research studies into consistent levels of evidence. These systems are based primarily on consensus expert opinion, and have not been validated to any extent. The use of different systems does not allow for effective communication between users; there is a lack of accord even between users of the same system. The GRADE working group has devised a new rating system that attempts to address deficiencies seen within other systems.

We have developed an assessment of students' ability to solve standard textbook style problems and are currently engaged in the validation and revision process. The assessment covers the topics of force and motion, conservation of momentum and conservation of energy at a level consistent with most calculus-based, introductory physics courses. This tool is discussed in more detail in an accompanying paper by Marx and Cummings. [1] Here we present preliminary beta-test data collected at four schools during the 2009/2010 academic year. Data include both pre- and post-instruction results for introductory physics courses as well as results for physics majors in later years. In addition, we present evidence that right/wrong grading may well be a perfectly acceptable grading procedure for a course-level assessment of this type.

Distinguishing between low- and high-grade prostate cancers (PCa) is important, but biopsy may underestimate the actual grade of cancer. We have previously shown that urine/plasma-based prostate-specific biomarkers can predict high grade PCa. Our objective was to determine the accuracy of a test using cell-free RNA levels of biomarkers in predicting prostatectomy results. This multicenter community-based prospective study was conducted using urine/blood samples collected from 306 patients. All recruited patients were treatment-naïve, without metastases, and had been biopsied, designated a Gleason Score (GS) based on biopsy, and assigned to prostatectomy prior to participation in the study. The primary outcome measure was the urine/plasma test accuracy in predicting high grade PCa on prostatectomy compared with biopsy findings. Sensitivity and specificity were calculated using standard formulas, while comparisons between groups were performed using the Wilcoxon Rank Sum, Kruskal-Wallis, Chi-Square, and Fisher's exact test. GS as assigned by standard 10-12 core biopsies was 3 + 3 in 90 (29.4%), 3 + 4 in 122 (39.8%), 4 + 3 in 50 (16.3%), and > 4 + 3 in 44 (14.4%) patients. The urine/plasma assay confirmed a previous validation and was highly accurate in predicting the presence of high-grade PCa (Gleason ≥3 + 4) with sensitivity between 88% and 95% as verified by prostatectomy findings. GS was upgraded after prostatectomy in 27% of patients and downgraded in 12% of patients. This plasma/urine biomarker test accurately predicts high grade cancer as determined by prostatectomy with a sensitivity at 92-97%, while the sensitivity of core biopsies was 78%. © 2018 Wiley Periodicals, Inc.

Periodontal disease is closely related to type 2 diabetes and is an important complication of diabetes. There are few studies about the relationship the glycohemoglobin levels with severity of periodontitis in non-diabetic population. We therefore planned this study to evaluate the glycohemoglobin levels with severity of periodontitis in non-diabetic population. This study was conducted on 50 age and gender matched subjects in each of the three groups (according to the grades of mobility in periodontitis), a total of 150 non-diabetic periodontitis patients (Grade 1, Grade 2, and Grade 3 mobility) and 50 non-diabetic periodontitis patients with Grade 0 mobility (controls), in collaboration with the Department of Periodontics of Dental College and Department of Biochemistry, PGIMS, Rohtak, Haryana. After obtaining informed consent, fasting venous blood samples of all the non-diabetic periodontitis patients of all grades were collected aseptically for HbA1c, plasma glucose, and serum C-reactive protein (CRP) estimation. A total of 150 non-diabetic periodontitis patients (Grade 1, Grade 2, and Grade 3 mobility) and 50 age and gender matched controls participated in the study. There was no significant difference in fasting plasma glucose and postprandial plasma glucose in non-diabetic periodontitis patients with Grade 1, Grade 2, and Grade 3 mobility as compared to controls, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 2, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 3 and non-diabetic periodontitis patients with Grade 2 mobility as compared to Grade 3. Glycohemoglobin and serum C-reactive protein levels were significantly increased in non-diabetic periodontitis patients with Grade 1, Grade 2, and Grade 3 mobility as compared to controls, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 3 and non-diabetic periodontitis patients with Grade 2 mobility as compared to Grade 3. The difference of serum C-reactive protein levels were significant. However, glycohemoglobin levels were non-significant between non-diabetic periodontitis patients with Grade 1 and Grade 2 mobility. The evidence of association between periodontitis and increased glycohemoglobin increases attention to the diagnosis and treatment of periodontitis, consequently improving the patient's oral health and prevention of occurrence in future diabetes. An understanding of these correlations is important to allow dental health care providers to inform patients with periodontitis of their increased risks and to counsel such patients to seek additional medical assessment or intervention as indicated.

Patient education materials should be written at a level that is understandable for patients with low health literacy. The aims of this study are (1) to review the literature on readability of ophthalmic patient education materials and (2) to evaluate and revise our institution's patient education materials about glaucoma using evidence-based guidelines on writing for patients with low health literacy. A systematic search was conducted on the PubMed/MEDLINE database for studies that have evaluated readability level of ophthalmic patient education materials, and the reported readability scores were assessed. Additionally, we collected evidence-based guidelines for writing easy-to-read patient education materials, and these recommendations were applied to revise 12 patient education handouts on various glaucoma topics at our institution. Readability measures, including Flesch-Kincaid Grade Level (FKGL), and word count were calculated for the original and revised documents. The original and revised versions of the handouts were then scored in random order by two glaucoma specialists using the Suitability Assessment of Materials (SAM) instrument, a grading scale used to evaluate suitability of health information materials for patients. Paired t test was used to analyze changes in readability measures, word count, and SAM score between original and revised handouts. Finally, five glaucoma patients were interviewed to discuss the revised materials, and patient feedback was analyzed qualitatively. Our literature search included 13 studies that evaluated a total of 950 educational materials. Among the mean FKGL readability scores reported in these studies, the median was 11 (representing an eleventh-grade reading level). At our institution, handouts' readability averaged a tenth-grade reading level (FKGL = 10.0 ± 1.6), but revising the handouts improved their readability to a sixth-grade reading level (FKGL = 6.4 ± 1.2) (p < 0.001). Additionally, the mean SAM score of our institution's handouts improved from 60 ± 7 % (adequate) for the original versions to 88 ± 4 % (superior) for the revised handouts (p < 0.001). Our systematic review of the literature reveals that ophthalmic patient education materials are consistently written at a level that is too high for many patients to understand. Our institution's experience suggests that applying guidelines on writing easy-to-understand material can improve the readability and suitability of educational materials for patients with low health literacy.

To evaluate manual and semiautomated grading techniques for assessing decreased fundus autofluorescence (DAF) in patients with Stargardt disease phenotype. Certified reading center graders performed manual and semiautomated (region finder-based) grading of confocal scanning laser ophthalmoscopy (cSLO) fundus autofluorescence (FAF) images for 41 eyes of 22 patients. Lesion types were defined based on the black level and sharpness of the border: definite decreased autofluorescence (DDAF), well, and poorly demarcated questionably decreased autofluorescence (WDQDAF, PDQDAF). Agreement in grading between the two methods and inter- and intra-grader agreement was assessed by kappa coefficients (κ) and intraclass correlation coefficients (ICC). The mean ± standard deviation (SD) area was 3.07 ± 3.02 mm for DDAF (n = 31), 1.53 ± 1.52 mm for WDQDAF (n = 9), and 6.94 ± 10.06 mm for PDQDAF (n = 17). The mean ± SD absolute difference in area between manual and semiautomated grading was 0.26 ± 0.28 mm for DDAF, 0.20 ± 0.26 mm for WDQDAF, and 4.05 ± 8.32 mm for PDQDAF. The ICC (95% confidence interval) for method comparison was 0.992 (0.984-0.996) for DDAF, 0.976 (0.922-0.993) for WDQDAF, and 0.648 (0.306-0.842) for PDQDAF. Inter- and intra-grader agreement in manual and semiautomated quantitative grading was better for DDAF (0.981-0.996) and WDQDAF (0.995-0.999) than for PDQDAF (0.715-0.993). Manual and semiautomated grading methods showed similar levels of reproducibility for assessing areas of decreased autofluorescence in patients with Stargardt disease phenotype. Excellent agreement and reproducibility were observed for well demarcated lesions.

The Internet has become a major resource for patients; however, patient education materials are frequently written at relatively high levels of reading ability. The purpose of this study was to evaluate the readability of patient education materials on the American Academy of Orthopaedic Surgeons (AAOS) web site. Readability scores were calculated for all patient education articles on the AAOS web site using 5 algorithms: Flesch Reading Ease, Flesch-Kincaid Grade Level, SMOG (Simple Measure of Gobbledygook) Grade, Coleman-Liau Index, and Gunning-Fog Index. The mean readability scores were compared across the anatomic categories to which they pertained. Using a liberal measure of readability, the Flesch-Kincaid Grade Level, 3.9% of articles were written at or below the recommended sixth-grade reading level, and 84% of the articles were written above the eighth-grade reading level. Articles in the present study had a lower mean Flesch-Kincaid Grade Level than those available in 2008 (p < 0.00005). Articles categorized as "Hand & Wrist" or "Foot & Ankle" had significantly lower mean Flesch-Kincaid Grade Level scores than the mean for all categories (p < 0.0005). Regardless of the algorithm used, the mean readability levels of AAOS articles are higher than generally recommended. Although the mean Flesch-Kincaid Grade Level was lower in the present study than it was in 2008, a need remains to improve the readability of AAOS patient education articles. Ensuring that online patient education materials are written at an appropriate reading grade level would be expected to improve physician-patient communication.

To improve the occupational health management levels in electroplating enterprises with quantitative classification measures and to provide a scientific basis for the prevention and control of occupational hazards in electroplating enterprises and the protection of workers' health. A quantitative classification table was created for the occupational health management in electroplating enterprises. The evaluation indicators included 6 items and 27 sub-items, with a total score of 100 points. Forty electroplating enterprises were selected and scored according to the quantitative classification table. These electroplating enterprises were classified into grades A, B, and C based on the scores. Among 40 electroplating enterprises, 11 (27.5%) had scores of >85 points (grade A), 23 (57.5%) had scores of 60∼85 points (grade B), and 6 (15.0%) had scores of <60 points (grade C). Quantitative classification management for electroplating enterprises is a valuable attempt, which is helpful for the supervision and management by the health department and provides an effective method for the self-management of enterprises.

Embedded optical waveguide technology for optical printed circuit boards (OPCBs) has advanced considerably over the past decade both in terms of materials and achievable waveguide structures. Two distinct classes of planar graded index multimode waveguide have recently emerged based on polymer and glass materials. We report on the suitability of graded index polymer waveguides, fabricated using the Mosquito method, and graded index glass waveguides, fabricated using ion diffusion on thin glass foils, for deployment within future data center environments as part of an optically disaggregated architecture. To this end, we first characterize the wavelength dependent performance of different waveguide types to assess their suitability with respect to two dominant emerging multimode transceiver classes based on directly modulated 850 nm VCSELs and 1310 silicon photonics devices. Furthermore we connect the different waveguide types into an optically disaggregated data storage system and characterize their performance with respect to different common high speed data protocols used at the intra and inter rack level including 10 Gb Ethernet and Serial Attached SCSI.

This study demonstrates the utility of applying a causal indicator modeling framework to investigate important predictors of reading comprehension in third, seventh, and tenth grade students. The results indicated that a 4-factor multiple indicator multiple indicator cause (MIMIC) model of reading comprehension provided adequate fit at each grade level. This model included latent predictor constructs of decoding, verbal reasoning, nonverbal reasoning, and working memory and accounted for a large portion of the reading comprehension variance (73% to 87%) across grade levels. Verbal reasoning contributed the most unique variance to reading comprehension at all grade levels. In addition, we fit a multiple group 4-factor MIMIC model to investigate the relative stability (or variability) of the predictor contributions to reading comprehension across development (i.e., grade levels). The results revealed that the contributions of verbal reasoning, nonverbal reasoning, and working memory to reading comprehension were stable across the three grade levels. Decoding was the only predictor that could not be constrained to be equal across grade levels. The contribution of decoding skills to reading comprehension was higher in third grade and then remained relatively stable between seventh and tenth grade. These findings illustrate the feasibility of using MIMIC models to explain individual differences in reading comprehension across the development of reading skills. PMID:25821346

This study examined the prevalence and correlates of street racing among adolescents derived from the 2009 Ontario Student Drug Use and Health Survey (OSDUHS), an epidemiological survey of students in Ontario, Canada. The key response variable, self-reported street racing in past year, was examined in relation to grade level, rural/urban, school marks, cannabis use, drinking and driving, cannabis use and driving, and property, physical, drugs, and weapons delinquencies. All survey estimates were weighted, and variance and statistical tests were corrected for the complex sampling design. Of the 3053 9th- to 12th-graders (66% response rate), 5.6 percent of high-schoolers (an estimated 42,000 in the province) and (20.4% of grade 11 and 12 students with an advanced-level or full license) reported driving a car, truck, or sport utility vehicle (SUV) in a street race in the 12 months before the survey. Logistic regression analysis of the advanced-level or fully licensed students in grades 11 and 12 found that males compared to females and students in grade 11 compared to students in grade 12 had significantly higher adjusted odds of street racing. Supportive of problem behavior theory, students who reported property and drug delinquencies compared to students not engaging in these delinquencies also had significantly higher adjusted odds of street racing. This first population-based study in North America suggested that the prevalence of street racing at 1 in 5 of advanced or fully licensed high-schoolers in grades 11 and 12 poses significant public health concerns, especially related to the potential for unintentional injury.

To determine the relationship of the van Herick angle grading system with the level of iris insertion and peripheral iris configuration. Observational study. Eye department, Combined Military Hospital, Malir Cantt., Karachi, from May to October 2015. Sixty-five eyes of 65 patients were recruited. Anterior chamber depth at the temporal limbus was measured as a fraction of corneal section thickness using van Herick technique and graded on the standard 4-point scale of the van Herick grading system. Gonioscopy of the temporal quadrant was performed with a Posner 4 mirror goniolens and both the true level of iris insertion and peripheral iris configuration were recorded on a 4-point scale so as to equate with the van Herick 4-point grading system. Spearman's rho test was applied to determine the relationship of the van Herick grading system with level of iris root insertion and peripheral iris configuration. Amoderate positive correlation between van Herick grade and peripheral iris configuration was found which was statistically significant (rs=0.42, p < 0.001). Astatistically significant and moderate positive correlation was also detected between van Herick grade and the level of iris insertion (rs=0.45, p < 0.001). The van Herick grade has a moderately positive relationship with the peripheral iris configuration and true level of iris insertion.

The occurrence of dampness and mold in the indoor environment is associated with respiratory-related disease outcomes. Thus, it is pertinent to know the magnitude of such indoor environment problems to be able to estimate the potential health impact in the population. In the present study, the moisture damage in 10,112 Norwegian dwellings was recorded based on building inspection reports. The levels of moisture damage were graded based on a condition class (CC), where CC0 is immaculate and CC1 acceptable (actions not required), while CC2 and CC3 indicate increased levels of damage that requires action. Of the 10,112 dwellings investigated, 3125 had verified moisture or mold damage. This amounts to 31% of the surveyed dwellings. Of these, 27% had CC2 as the worst grade, whereas 4% had CC3 as the worst grade level. The room types and building structures most prone to moisture damage were (in rank order) crawl spaces, basements, un-insulated attics, cooling rooms, and bathrooms. The high proportion of homes with moisture damage indicate a possible risk for respiratory diseases in a relatively large number of individuals, even if only the more extensive moisture damages and those located in rooms where occupants spend the majority of their time would have a significant influence on adverse health effects.

Irisin, a recently identified myokine, is implicated in protecting mice from obesity. This study was designed to examine the relation of irisin levels in serum and synovial fluid (SF) with the radiographic severity of osteoarthritis (OA). Our study included 215 patients with knee OA. Irisin levels in serum and SF were evaluated using an enzyme-linked immunosorbent assay. The progression of OA was assessed using Kellgren-Lawrence grading system. Knee OA patients had lower serum irisin concentrations and increased serum C-reactive protein (CRP) levels compared with healthy controls. There were markedly decreased irisin levels in both the serum and the SF, as well as increased serum CRP levels of knee OA patients with Kellgren and Lawrence (KL) grade 4 compared with patients classified as KL grade 2 and 3. Furthermore, patients with KL grade 3 showed markedly reduced serum and SF levels of irisin, as well as increased serum CRP levels compared with patients classified as KL grade 2. Irisin levels in serum and SF of knee OA patients were negatively correlated with disease severity evaluated by KL grading criteria. Irisin levels in the serum and SF of knee OA patients were negatively correlated with disease severity evaluated by the radiographic KL grading criteria.

Quasi-experimental clinical trial. This study compared outcomes from graded exercise and graded exposure activity prescriptions for patients participating in a multidisciplinary rehabilitation program for chronic low back pain. Our primary purpose was to investigate whether pain and disability outcomes differed based on treatment received (graded exercise or graded exposure). Our secondary purpose was to investigate if changes in selected psychological factors were associated with pain and disability outcomes. Behavioral interventions have been advocated for decreasing pain and disability from low back pain, yet relatively few comparative studies have been reported in the literature. Consecutive sample with chronic low back pain recruited over a 16-month period from an outpatient chronic pain clinic. Patients received physical therapy supplemented with either graded exercise (n=15) or graded exposure (n=18) principles. Graded exercise included general therapeutic activities and was progressed with a quota-based system. Graded exposure included specific activities that were feared due to back pain and was progressed with a hierarchical exposure paradigm. Psychological measures were pain-related fear (Fear-Avoidance Beliefs Questionnaire, Tampa Scale for Kinesiophobia, Fear of Pain Questionnaire), pain catastrophizing (Coping Strategies Questionnaire), and depressive symptoms (Beck Depression Inventory). Primary outcome measures were pain intensity (visual analog scale) and self-report of disability (modified Oswestry Disability Questionnaire). Statistically significant improvements (P<.01) were observed for pain intensity and disability at discharge. The rate of improvement did not differ based on behavioral intervention received (P>.05 for these comparisons). Overall, 50% of patients met criterion for minimally important change for pain intensity, while 30% met this criterion for disability. Change in depressive symptoms was associated with change in pain intensity, while change in pain catastrophizing was associated with change in disability. Physical therapy supplemented with graded exercise or graded exposure resulted in equivalent clinical outcomes for pain intensity and disability. The overall treatment effects were modest in this setting. Instead of being associated with a specific behavioral intervention, reductions in pain and disability were associated with reductions in depressive symptoms and pain catastrophizing, respectively.

The aim of the study was to evaluate somatostatin receptor expression in non-I-concentrating metastatic differentiated thyroid carcinoma by Ga-DOTATATE PET-CT/Tc-HYNIC-TOC scintigraphy and to determine the feasibility of Lu-DOTATATE (therapeutic analog) therapy in cases with positive Ga-DOTATATE PET-CT/Tc-HYNIC-TOC scintigraphy. In this research study, 19 patients diagnosed with differentiated thyroid carcinoma with non-iodine-concentrating metastasis with elevated serum thyroglobulin levels, attending thyroid outpatient department for follow-up, underwent Ga-DOTATATE PET-CT/Tc-HYNIC-TOC scan for the evaluation of positivity of somatostatin receptor (SSTR). Based on the visual grading, SSTR-positive lesions were graded into 4 categories (grades I-IV) in comparison with the hepatic uptake on the scan. Patients with grades III and IV uptake in lesions (equal to or more than hepatic uptake on scan) were scheduled for Lu-DOTATATE administration. Posttherapy Lu-DOTATATE scan was undertaken during discharge from the isolation ward. Of the 19 patients studied, 12 patients (63%) showed SSTR-positive lesion expression demonstrating uptake ranging from grade I-IV, and 7 patients (37%) did not demonstrate any tracer uptake. On a lesion-specific analysis, of the total 57 metastatic lesions, 4 lesions (7%) demonstrated grade I tracer uptake, 18 lesions (31%) grade II (less than liver), 2 lesions (3.5%) grade III (equal to liver uptake), and 1 lesion showed grade IV uptake (more than liver). Interestingly, an elevated serum chromogranin A level was documented in 3 of the patients with grades III and IV tumor uptake. A comparison of Ga-DOTATATE PET-CT and Tc-HYNIC-TOC in 4 patients who underwent both the scans demonstrated no significant differences in the tracer concentration in the metastatic lesions in any of the patients on visual grading. Based on the criterion of high tracer uptake and the patient consent, finally 2 of 3 patients were treated with Lu-DOTATATE. On follow-up after 3 months, a significant fall in serum thyroglobulin level was noted in one of the patients, and the other patient was lost to follow-up. Avid expression of the SSTR on Ga-DOTATATE PET-CT/Tc-HYNIC-TOC scintigraphy in non-I-concentrating metastatic differentiated thyroid cancer is observed in a relatively low fraction of patients that could favor the feasibility of Lu-DOTATATE therapy. Although seen in a small fraction, taking into account that no treatment exists in this group, somatostatin receptor-targeted imaging can be an alternative diagnostic modality in the therapeutic decision making with peptide receptor radionuclide therapy and monitoring. The documentation of elevated serum chromogranin A level in 3 patients with intense tracer uptake could suggest a possible neuroendocrine differentiation in the affected tissues leading to the expression of chromogranin A along with SSTR-avid expression. This observation needs to be explored in future studies. No definite conclusions can be drawn on the therapeutic efficacy of the Lu-DOTATATE therapy in this group at present, and more prospective research is required in this area.

This paper introduces new longitudinal network data from the "Promoting School-Community-University Partnerships to Enhance Resilience" or "PROSPER" peers project. In 28 communities, grade-level sociometric friendship nominations were collected from two cohorts of middle school students as they moved from 6(th), to 9(th) grade. As an illustration and description of these longitudinal network data, this paper describes the school popularity structure, changes in popularity position, and suggests linkages between popularity trajectory and substance use. In the cross-section, we find that the network is consistent with a hierarchical social organization, but exhibits considerable relational change in both particular friends and position at the individual level. We find that both the base level of popularity and the variability of popularity trajectories effect substance use.

This study was conducted to analyze to what extent university students exhibit healthy lifestyles and which sociodemographic variables influence healthy lifestyles. 4809 university students randomly selected were measured by use of the Healthy Lifestyle Scale for University Students questionnaire. When controlling for the other variables, the total healthy lifestyles score was predicted by gender, grade, father's level of education, and type of institution; exercise behaviour was partially predicted by gender, grade, type of institution, and family monthly income; regular behaviour was modulated by gender, grade, type of institution, family monthly income, and father's educational level; nutrition behaviour was partially affected by type of institution, family monthly income, and father's educational level; health risk behaviour was modulated by gender, mother's level of education, and family monthly income; health responsibility was modulated by gender, grade, type of institution, and father's educational level; social support was modulated by gender, grade, and father's educational level; stress management was modulated by gender, grade, type of institution, and mother's education level; life appreciation was modulated by grade, type of institution, and mother's educational level. These influences should be taken into account in designing interventions for specific socio-demographic profiles that might be at higher risk for certain behaviours. PMID:23935418

This study examined the contributions of vocabulary and spelling to the reading comprehension of students in grades 6-10 who were and were not classified as English language learners. Results indicate that vocabulary accounted for greater between-grade differences and unique variance (Δ R 2 = .11 to .31) in comprehension as compared to spelling (Δ R 2 = .01 to .09). However, the contribution of spelling to comprehension was higher in the upper grade levels included in this cross-sectional analysis and functioned as a mediator of the impact of vocabulary knowledge at all levels. The direct effect of vocabulary was strong but lower in magnitude at each successive grade level from .58 in grade 6 to .41 in grade 10 while the indirect effect through spelling increased in magnitude at each successive grade level from .09 in grade 6 to .16 in grade 10. There were no significant differences between the language groups in the magnitude of the indirect impact, suggesting both groups of students relied more on both sources of lexical information in higher grades as compared to students in lower grades.

Structured literature review. The Scoliosis Research Society requested an assessment of the current state of peer-reviewed evidence regarding pediatric lumbar spondylolisthesis to identify what is known and what research remains essential to further understanding. Pediatric lumbar spondylolisthesis is common, yet no formal synthesis of the published literature regarding treatment has been previously performed. A comprehensive literature search was performed. From 6600 initial citations with abstract, 663 articles underwent full-text review. The best available evidence regarding surgical and medical/interventional treatment was provided by 51 studies. None of the studies were graded Level I or II evidence. Eighteen of the studies were Level III, representing the current best available evidence. Thirty-three of the studies were Level IV. Although studies suggest a benign course for "low grade" (<50% slip) isthmic spondylolisthesis, extensive literature suggests that a substantial number of patients present for treatment with pain and activity limitations. Pain resolution and return to activity is common with both medical/interventional and operative treatment. The role of medical/interventional bracing is not well established. Uninstrumented posterolateral fusion has been reported to produce good clinical results, but concerns regarding nonunion exist. Risk of slip progression is a specific concern in the "high grade" or dysplastic type. Although medical/interventional observation has been reported to be reasonable in a small series of asymptomatic high-grade slip patients, surgical treatment is commonly recommended to prevent progression. There is Level III evidence that instrumentation and reduction lowers the risk of nonunion, and that circumferential fusion is superior to posterior-only or anterior-only fusion. There is Level III evidence that patients with a higher slip angle are more likely to fail medical/interventional treatment of high-grade spondylolisthesis. The current "best available" evidence to guide the treatment of pediatric spondylolisthesis is presented. Level III; review of Level III studies. Copyright © 2017 Scoliosis Research Society.

A mathematical model describes the malignant transformation of low grade gliomas: Prognostic implications.

Gliomas are the most frequent type of primary brain tumours. Low grade gliomas (LGGs, WHO grade II gliomas) may grow very slowly for the long periods of time, however they inevitably cause death due to the phenomenon known as the malignant transformation. This refers to the transition of LGGs to more aggressive forms of high grade gliomas (HGGs, WHO grade III and IV gliomas). In this paper we propose a mathematical model describing the spatio-temporal transition of LGGs into HGGs. Our modelling approach is based on two cellular populations with transitions between them being driven by the tumour microenvironment transformation occurring when the tumour cell density grows beyond a critical level. We show that the proposed model describes real patient data well. We discuss the relationship between patient prognosis and model parameters. We approximate tumour radius and velocity before malignant transformation as well as estimate the onset of this process.

Examining the progression and consistency of thermal concepts: a cross-age study

2018-03-01

This cross-sectional study examined how the progression and consistency of students' understanding of thermal concepts in everyday contexts changes across the grade levels. A total of 656 Turkish students from Grade 8 (age 13-14), Grade 10 (age 15-16), and the first year of college (age 19-20) participated in the study. The data were analysed using statistical procedures (descriptive and inferential). Findings indicated a substantial progression in the students' scientific understanding of thermal concepts across grade levels. In addition, the students' alternative conceptions about thermal concepts generally decreased in frequency across grade levels, but certain alternative conceptions were observed in every grade level to a similar extent. Even though the number of students who consistently used scientific ideas increased across grade levels, the number of students who consistently used non-scientific ideas decreased across grade levels. However, the number of students who used scientific and non-scientific ideas inconsistently generally increased as they progressed in the science curriculum. These findings can be associated with either fragmentation or alternative conceptions that result from the gradual enrichment processes students experience when they try to integrate scientific concepts into their conceptual frameworks.

The purpose of this study was to examine prevalence rates of 5 types of beverage consumption by sociodemographic factors among 4th-, 8th-, and 11th-grade public school students in Texas. This study is based on secondary analyses of cross-sectional data from the 2004-2005 School Physical Activity and Nutrition study, a comprehensive surveillance study of energy balance-related behaviors and behavioral antecedents in a state-representative sample of 4th-, 8th-, and 11th-grade public school students in Texas (N = 23,190). Previous-day beverage consumption prevalence estimates were calculated for 5 types of beverages (i.e., fruit-flavored drinks, regular sodas, diet sodas, milk, and 100% fruit juice) by grade level, gender, ethnicity, school-level socioeconomic status, and metropolitan status. Logistic regression estimates of consumption prevalence were obtained for important sociodemographic indicators, including sex, grade, and ethnicity. Adjusted Wald tests were used to derive significance tests for sex differences in consumption, as sex emerged as a key determinant of consumption prevalence and varied systematically by type of beverage. The most commonly consumed beverage by all participants was milk. However, more than 50% of students also reported regular soda and fruit-flavored drink consumption during the previous day. Milk and fruit juice consumption showed a steady decline with grade level, while consumption of regular soda increased with grade level. By 11th grade, the prevalence of any beverage consumption, including milk and juice, was significantly greater among boys. Ethnic differences in sugar-sweetened beverage consumption were most prevalent in 8th and 11th grades, with the highest estimated prevalence of sugar-sweetened beverages (i.e., fruit-flavored drink and regular soda) consumption among African Americans. Differences in beverage consumption by school-level socioeconomic status and metropolitan status were small. These findings indicate that a large proportion of public elementary students in Texas are consuming sugar-sweetened beverages and that consumption of sugar-sweetened beverages varies by a range of sociodemographic factors. Given the important link between sugar-sweetened beverages and obesity in children, these findings can be used to tailor obesity prevention efforts to specific subpopulations for the promotion of healthier beverage consumption.

Readability of patient education materials on the American Orthopaedic Society for Sports Medicine website.

2014-11-01

The recommended readability of patient education materials by the American Medical Association (AMA) and National Institutes of Health (NIH) should be no greater than a sixth-grade reading level. However, online resources may be too complex for some patients to understand, and poor health literacy predicts inferior health-related quality of life outcomes. This study evaluated whether the American Orthopaedic Society for Sports Medicine (AOSSM) website's patient education materials meet recommended readability guidelines for medical information. We hypothesized that the readability of these online materials would have a Flesch-Kincaid formula grade above the sixth grade. All 65 patient education entries of the AOSSM website were analyzed for grade level readability using the Flesch-Kincaid formula, a widely used and validated tool to evaluate the text reading level. The average (standard deviation) readability of all 65 articles was grade level 10.03 (1.44); 64 articles had a readability score above the sixth-grade level, which is the maximum level recommended by the AMA and NIH. Mean readability of the articles exceeded this level by 4.03 grade levels (95% CI, 3.7-4.4; P < 0.0001). We found post-hoc that only 7 articles had a readability score ≤ an eighth-grade level, the average reading level of US adults. Mean readability of the articles exceeded this level by 2.03 grade levels (95% CI, 1.7-2.4; P < 0.0001). The readability of online AOSSM patient education materials exceeds the readability level recommended by the AMA and NIH, and is above the average reading level of the majority of US adults. This online information may be of limited utility to most patients due to a lack of comprehension. Our study provides a clear example of the need to improve the readability of specific education material in order to maximize the efficacy of multimedia sources.

The teacher-researcher taught students the Full Option Science System™ (FOSS) modules of sound (fourth grade) and solar energy (fifth grade) with the integration of creative drama activities in treatment classes. A 2 × 2 × (2) Mixed ANOVA was used to examine differences in the learning outcomes and attitudes toward science between groups (drama and non-drama) and grade levels (4th and 5th grades) over time (pre/post). Learning was measured using the tests included with the FOSS modules. A shortened version of the Three Dimension Elementary Science Attitude Survey measured attitudes toward science. Students in the drama treatment group had significantly higher learning gains ( F = 160.2, p < 0.001) than students in the non-drama control group with students in grade four reporting significantly greater learning outcomes ( F = 14.3, p < 0.001) than grade five. There was a significantly statistical decrease in student attitudes toward science ( F = 7.5, p < 0.01), though a small change. Creative drama was an effective strategy to increase science conceptual learning in this group of diverse elementary enrichment students when used as an active extension to the pre-existing inquiry-based science curriculum.

Previous studies of academic achievement of children with oral clefts have mostly relied on small, clinic-based samples prone to ascertainment bias. In the first study in the United States to use a population-based sample with direct assessment, we evaluated the academic achievement of children with oral clefts relative to their classmates. Children born with isolated oral clefts in Iowa from 1983 to 2003 were identified from the Iowa Registry for Congenital and Inherited Disorders and matched to unaffected classmates by gender, school/school district, and month and year of birth. Academic achievement was assessed by using standardized tests of academic progress developed by the Iowa Testing Programs. Iowa Testing Programs data were linked to birth certificates for all children. Regression models controlled for household demographic and socioeconomic factors. The analytical sample included 588 children with clefts contributing 3735 child-grade observations and 1874 classmates contributing 13 159 child-grade observations. Children with oral clefts had lower scores than their classmates across all domains and school levels, with a 5-percentile difference in the overall composite score. Children with clefts were approximately one-half grade level behind their classmates and had higher rates of academic underachievement and use of special education services by 8 percentage points. Group differences were slightly lower but remained large and significant after adjusting for many background characteristics. Children with oral clefts underperformed across all academic areas and grade levels compared with their classmates. The results support a model of early testing and intervention among affected children to identify and reduce academic deficits. Copyright © 2014 by the American Academy of Pediatrics.

To perform a systematic review of the literature on the control of oral biofilms and the incidence of nosocomial pneumonia, in addition to assessing and classifying studies as to the grade of recommendation and level of evidence. The review was based on PubMed, LILACS, and Scopus databases, from January 1st, 2000 until December 31st, 2012. Studies evaluating oral hygiene care related to nosocomial infections in patients hospitalized in intensive care units were selected according to the inclusion criteria. Full published articles available in English, Spanish, or Portuguese, which approached chemical or mechanical oral hygiene techniques in preventing pneumonia, interventions performed, and their results were included. After analysis, the articles were classified according to level of evidence and grade of recommendation according to the criteria of the Oxford Centre for Evidence-Based Medicine. A total of 297 abstracts were found, 14 of which were full articles that met our criteria. Most articles included a study group with chlorhexidine users and a control group with placebo users for oral hygiene in the prevention of pneumonia. All articles were classified as B in the level of evidence, and 12 articles were classified as 2B and two articles as 2C in grade of recommendation. It was observed that the control of oral biofilm reduces the incidence of nosocomial pneumonia, but the fact that most articles had an intermediate grade of recommendation makes clear the need to conduct randomized controlled trials with minimal bias to establish future guidelines for oral hygiene in intensive care units.

To determine whether the online patient education material offered by the American College of Cardiology (ACC) and the American Heart Association (AHA) is written at a higher level than the 6th-7th grade level recommended by the National Institute of Health (NIH). Online patient education material from each website was subjected to reading grade level (RGL) analysis using the Readability Studio Professional Edition. One-sample t testing was used to compare the mean RGLs obtained from 8 formulas to the NIH-recommended 6.5 grade level and 8th grade national mean. In total, 372 articles from the ACC website and 82 from the AHA were studied. Mean (±SD) RGLs for the 454 articles were 9.6 ± 2.1, 11.2 ± 2.1, 11.9 ± 1.6, 10.8 ± 1.6, 9.7 ± 2.1, 10.8 ± 0.8, 10.5 ± 2.6, and 11.7 ± 3.5 according to the Flesch-Kincaid grade level (FKGL), Simple Measure of Gobbledygook (SMOG Index), Coleman-Liau Index (CLI), Gunning-Fog Index (GFI), New Dale-Chall reading level formula (NDC), FORCAST, Raygor Readability Estimate (RRE), and Fry Graph (Fry), respectively. All analyzed articles had significantly higher RGLs than both the NIH-recommended grade level of 6.5 and the national mean grade level of 8 (p < 0.00625). Patient education material provided on the ACC and AHA websites is written above the NIH-recommended 6.5 grade level and 8th grade national mean reading level. Additional studies are required to demonstrate whether lowering the RGL of this material improves outcomes among patients with cardiovascular disease. © 2017 S. Karger AG, Basel.

A Computer-Aided Distinction Method of Borderline Grades of Oral Cancer

Sami, Mustafa M.; Saito, Masahisa; Muramatsu, Shogo; Kikuchi, Hisakazu; Saku, Takashi

We have developed a new computer-aided diagnostic system for differentiating oral borderline malignancies in hematoxylin-eosin stained microscopic images. Epithelial dysplasia and carcinoma in-situ (CIS) of oral mucosa are two different borderline grades similar to each other, and it is difficult to distinguish between them. A new image processing and analysis method has been applied to a variety of histopathological features and shows the possibility for differentiating the oral cancer borderline grades automatically. The method is based on comparing the drop-shape similarity level in a particular manually selected pair of neighboring rete ridges. It was found that the considered similarity level in dysplasia was higher than those in epithelial CIS, of which pathological diagnoses were conventionally made by pathologists. The developed image processing method showed a good promise for the computer-aided pathological assessment of oral borderline malignancy differentiation in clinical practice.

White, Terri Renee'

The primary purpose of the study was to examine different variables (i.e. science process skill ability, science attitudes, and parents' levels of expectation for their children in science, which may impinge on science education differently for males and females in grades five, seven, and nine. The research question addressed by the study was: What are the differences between science process skill ability, science attitudes, and parents' levels of expectation in science on the academic success of fifth, seventh, and ninth graders in science and do effects differ according to gender and grade level? The subjects included fifth, seven, and ninth grade students ( n = 543) and their parents (n = 474) from six rural, public elementary schools and two rural, public middle schools in Southern Mississippi. A two-way (grade x gender) multivariate analysis of variance (MANOVA) was used to determine the differences in science process skill abilities of females and males in grade five, seven, and nine. An additional separate two-way multivariate analysis of variance (grade x gender) was also used to determine the differences in science attitudes of males and females in grade five, seven, and nine. A separate analysis of variance (PPSEX [parent's gender]) with the effects being parents' gender was used to determine differences in parents' levels of expectation for their childrens' performance in science. An additional separate analysis of variance (SSEX [student's gender]) with the effects being the gender of the student was also used to determine differences in parents' levels of expectation for their childrens' performance in science. Results of the analyses indicated significant main effects for grade level (p < .001) and gender (p < .001) on the TIPS II. There was no significant grade by gender interaction on the TIPS II. Results for the TOSRA also indicated a significant main effect for grade (p < .001) and the interaction of grade by sex ( p < .001). On variable ATT 5 (enjoyment of science lessons), males' attitudes toward science decreased across the grade levels; whereas, females decreased from grade five to seven, but showed a significant increase from grade seven to nine. Results from the analysis of variance with the parent's gender as the main effect showed no significant difference. The analysis of variance with student's gender as the main effect showed no significant difference.

Hepatitis B virus (HBV) DNA levels and liver histological necroinflammation grades are correlated with the antiviral efficacy. It is necessary to clarify the relationship between HBV replication levels apportioned by the same hepatic parenchyma cell volume and severity of liver histological necroinflammation grades in both hepatitis B e antigen (HBeAg)-positive and HBeAg-negative chronic hepatitis B. The serum HBV DNA levels apportioned by the same hepatic parenchyma cell volume were compared between HBeAg-positive and HBeAg-negative chronic hepatitis B as well as among liver histological necroinflammation grades 1, 2, 3 and 4, respectively. There were no differences in the serum HBV DNA levels between HBeAg-positive and HBeAg-negative chronic hepatitis B as well as among liver histological necroinflammation grades 1, 2, 3 and 4. However, there were differences in the serum HBV DNA levels apportioned by the same hepatic parenchyma cell volume among liver histological necroinflammation grades 1, 2, 3 and 4 in both HBeAg-positive and HBeAg-negative chronic hepatitis B, respectively. There were no differences in HBV DNA levels with the same liver histological necroinflammation grade activated by HBV wild-type and variant strains. After the differences in hepatic parenchyma cell volume for HBV replication of the same liver histological necroinflammation grade accompanied by different hepatic fibrosis stages were adjusted, the serum HBV DNA level apportioned by the same hepatic parenchyma cell volume was correlated with the severity of liver histological necroinflammation grade. © 2011 Blackwell Publishing Ltd.

2017-06-01

Based on the Federal Railway Administration (FRA) database, there were 25,945 highway-rail crossing accidents in the United States between 2002 and 2011. With an extensive research, analysis results showed that there were substantial differences between rural and urban areas at highway-rail grade crossings. However, there is no published study specific on driver's injury severity at highway-rail grade crossings classified by area types. Using an ordered probit modelling approach, the study explores the determinants of driver-injury severity at rural highway-rail grade crossings compared with urban highway-rail grade crossings. The analysis found that motor vehicle driver's injury level at rural highway-rail grade crossing is extremely higher than urban area. Compared to collisions at urban area, collisions happened at rural area tend to result in more severe injuries. These crashes were more prevalent if vehicle drivers are driving at a high speed or the oncoming trains are high-speed. Moreover, highway-rail grade crossing accidents were more likely to occur at rural area without pavement and lighting.

Chronic early school absence (preschool through third grade) is associated with school failure. The presence of school nurses may lead to fewer absences, and nurse practitioners in school-based health centers (SBHCs) can facilitate a healthier population resulting in improved attendance. Efforts to get students back to school are unexplored in nursing literature. This article describes a nursing intervention to decrease early school absence in two elementary schools K-3 (N = 449) and a Head Start program (N = 130). The Head Start Family Nurse Practitioner (FNP) contacted families of chronically and excessively absent students by telephone, clinic visit at school, or home visit. The aggregate percentage attendance was evaluated by grades (preschool to third grade), schools (Head Start, Elementary Schools 1 and 2), and grades and schools and compared with publicly available school district aggregate data. There were statistically significant increases in attendance from Year 1 to Year 2 at p < .05 at the elementary level but not at the Head Start level. Student demographics, types of contacts, absence reasons (including sick child), and medical diagnoses are described.

Prognostic relevance of Fédération Nationale des Centres de Lutte Contre le Cancer grade and MDM2 amplification levels in dedifferentiated liposarcoma: a study of 50 cases.

Dedifferentiated liposarcoma represents a form of liposarcoma composed of a non-lipogenic sarcoma associated with well-differentiated liposarcoma. The prognostic significance of histological grading of the dedifferentiated component remains to be elucidated due to vague grading criteria employed in previous studies. Molecular markers of tumor behavior, including amplification levels of murine double minute-2 (MDM2) and cyclin-dependent kinase-4 (CDK4) genes, have been explored in a limited number of cases. Here we investigate whether 'Fédération Nationale des Centres de Lutte Contre le Cancer' (FNCLCC) grade and MDM2 gene amplification levels have prognostic value in dedifferentiated liposarcoma in terms of local recurrence and disease-specific survival. Fifty cases were retrieved, reviewed and FNCLCC grade was scored for the dedifferentiated component. Testing for MDM2 gene amplification was performed by fluorescence in situ hybridization. Amplification was categorized as high level (≥20 copies) and as low level (<20 copies). Follow-up data was obtained through chart review. Log-rank test and Cox proportional hazard models were used to determine the effect of grade and level of MDM2 amplification on outcomes. Our series includes 50 patients (male n=28, female n=22) with an average age of 63 years (range, 28-88) and a median follow-up of 28 months (range, 2-120). Tumors were graded as grade 1 (6%), grade 2 (58%), and grade 3 (36%). When adjusted for age, sex, site, tumor size, and margin status, grade 3 patients had a higher recurrence rate than grades 1 and 2 (HR=2.07, 95% CI: 1.24, 7.62; P=0.015). Patients with high-level MDM2 amplification had higher recurrence rate on univariate analysis (P=0.028), but not on multivariate analysis (HR=1.69, 95% CI: 0.73, 3.94; P=0.221). FNCLCC grade 3 dedifferentiation confers a worse prognosis in dedifferentiated liposarcoma in terms of local recurrence. MDM2 amplification level remains a useful diagnostic tool in dedifferentiated liposarcoma, but has no prognostic value in terms of local recurrence.

Purpose: To evaluate effectiveness and safety of spot-scanning-based proton radiotherapy (PT) in skull-base chordomas and chondrosarcomas. Methods and Materials: Between October 1998 and November 2005, 64 patients with skull-base chordomas (n = 42) and chondrosarcomas (n = 22) were treated at Paul Scherrer Institute with PT using spot-scanning technique. Median total dose for chordomas was 73.5 Gy(RBE) and 68.4 Gy(RBE) for chondrosarcomas at 1.8-2.0 Gy(RBE) dose per fraction. Local control (LC), disease specific survival (DSS), and overall survival (OS) rates were calculated. Toxicity was assessed according to CTCAE, v. 3.0. Results: Mean follow-up period was 38 months (range, 14-92 months).more » Five patients with chordoma and one patient with chondrosarcoma experienced local recurrence. Actuarial 5-year LC rates were 81% for chordomas and 94% for chondrosarcomas. Brainstem compression at the time of PT (p = 0.007) and gross tumor volume >25 mL (p = 0.03) were associated with lower LC rates. Five years rates of DSS and OS were 81% and 62% for chordomas and 100% and 91% for chondrosarcomas, respectively. High-grade late toxicity consisted of one patient with Grade 3 and one patient with Grade 4 unilateral optic neuropathy, and two patients with Grade 3 central nervous system necrosis. No patient experienced brainstem toxicity. Actuarial 5-year freedom from high-grade toxicity was 94%. Conclusions: Our data indicate safety and efficacy of spot-scanning based PT for skull-base chordomas and chondrosarcomas. With target definition, dose prescription and normal organ tolerance levels similar to passive-scattering based PT series, complication-free, tumor control and survival rates are at present comparable.« less

Spatio-Temporal Dynamic Analysis of Sustainable Development in China Based on the Footprint Family.

The existing index systems on sustainable evaluation are mostly based on a multi index comprehensive evaluation method. The main disadvantage of this approach is that the selection and assignment of evaluation indexes are greatly influenced by subjective factors, which can result in poor comparability of results. By contrast, the Footprint Family (including ecological footprint, carbon footprint, and water footprint) is not affected by subjective factors. The Footprint Family also covers the basic tenets of sustainable development. This paper proposes use of a sustainable development evaluation index system based on the principle of the Footprint Family, and including the ecological pressure index ( EPI ), the ecological occupancy index ( EOI ), the ecological economic coordination index ( EECI ), the GHG (Greenhouse Gas) emission index ( CEI ), the water resources stress index ( WSI ), and the sustainable development index ( SDI ). Furthermore, a standard for grading the evaluated results based on global benchmarks is formulated. The results of an empirical study in China were the following. The development situation deteriorated from 1990 to 2015. The results showed that the SDI decreased from a medium level (grade 5) to a lower-medium level (grade 4). The results of this empirical study also showed that the method of evaluation can avoid the influence of subjective factors and can be used in the evaluation of sustainable development for various temporal and spatial conditions.

2003-01-01

A new food-grade host/vector system for Lactobacillus casei based on lactose selection was constructed. The wild-type non-starter host Lb. casei strain E utilizes lactose via a plasmid-encoded phosphotransferase system. For food-grade cloning, a stable lactose-deficient mutant was constructed by deleting a 141-bp fragment from the phospho-beta-galactosidase gene lacG via gene replacement. The deletion resulted in an inactive phospho-beta-galactosidase enzyme with an internal in-frame deletion of 47 amino acids. A complementation plasmid was constructed containing a replicon from Lactococcus lactis, the lacG gene from Lb. casei, and the constitutive promoter of pepR for lacG expression from Lb. rhamnosus. The expression of the lacG gene from the resulting food-grade plasmid pLEB600 restored the ability of the lactose-negative mutant strain to grow on lactose to the wild-type level. The vector pLEB600 was used for expression of the proline iminopeptidase gene pepI from Lb. helveticus in Lb. casei. The results show that the food-grade expression system reported in this paper can be used for expression of foreign genes in Lb. casei.

2015-11-01

The hand pattern used during manual wheelchair propulsion (i.e., full-cycle hand path) can provide insight into an individual's propulsion technique. However, previous analyses of hand patterns have been limited by their focus on a single propulsion condition and reliance on subjective qualitative characterization methods. The purpose of this study was to develop a set of objective quantitative parameters to characterize hand patterns and determine the influence of propulsion speed and grade of incline on the patterns preferred by manual wheelchair users. Kinematic and kinetic data were collected from 170 experienced manual wheelchair users on an ergometer during three conditions: level propulsion at their self-selected speed, level propulsion at their fastest comfortable speed and graded propulsion (8%) at their level self-selected speed. Hand patterns were quantified using a set of objective parameters, and differences across conditions were identified. Increased propulsion speed resulted in a shift away from under-rim hand patterns. Increased grade of incline resulted in the hand remaining near the handrim throughout the cycle. Manual wheelchair users change their hand pattern based on task-specific constraints and goals. Further work is needed to investigate how differences between hand patterns influence upper extremity demand and potentially lead to the development of overuse injuries and pain.

Factors in seventh grade academics associated with performance levels on the tenth grade biology end of course test in selected middle and high schools in northwest Georgia

NASA Astrophysics Data System (ADS)

Ward, Jennifer Henry

This study attempted to identify factors in seventh grade academics that are associated with overall success in tenth grade biology. The study addressed the following research questions: Are there significant differences in performance levels in seventh grade Criterion Referenced Competency Test (CRCT) scores in science, math, reading, and language arts associated with performance categories in tenth grade biology End of Course Test (EOCT) and the following demographic variables : gender, ethnicity, socioeconomic status, disability category, and English language proficiency level? Is there a relationship among the categorical variables on the tenth grade biology EOCT and the same five demographic variables? Retrospective causal comparative research was used on a representative sample from the middle schools in three North Georgia counties who took the four CRCTs in the 2006-2007 school year, and took the biology EOCT in the 2009-2010 school year. Chi square was used to determine the relationships of the various demographic variables on three biology EOCT performance categories. Twoway ANOVA determined relationships between the seventh grade CRCT scores of students in the various demographic groups and their performance levels on the biology EOCT. Students' performance levels on the biology EOCT matched their performance levels on the seventh grade CRCTs consistently. Females performed better than males on all seventh grade CRCTs. Black and Hispanic students did worse than White and Asian/Asian Indian students on the math CRCT. Students living in poverty did worse on reading and language arts CRCTs than students who were better off. Special education students did worse on science, reading, and language arts CRCTs than students not receiving special education services. English language learners did worse than native English speakers on all seventh grade CRCTs. These findings suggest that remedial measures may be taken in the seventh grade that could impact performance levels on the biology EOCT.

The relationships between spatial ability, logical thinking, mathematics performance and kinematics graph interpretation skills of 12th grade physics students

NASA Astrophysics Data System (ADS)

Bektasli, Behzat

Graphs have a broad use in science classrooms, especially in physics. In physics, kinematics is probably the topic for which graphs are most widely used. The participants in this study were from two different grade-12 physics classrooms, advanced placement and calculus-based physics. The main purpose of this study was to search for the relationships between student spatial ability, logical thinking, mathematical achievement, and kinematics graphs interpretation skills. The Purdue Spatial Visualization Test, the Middle Grades Integrated Process Skills Test (MIPT), and the Test of Understanding Graphs in Kinematics (TUG-K) were used for quantitative data collection. Classroom observations were made to acquire ideas about classroom environment and instructional techniques. Factor analysis, simple linear correlation, multiple linear regression, and descriptive statistics were used to analyze the quantitative data. Each instrument has two principal components. The selection and calculation of the slope and of the area were the two principal components of TUG-K. MIPT was composed of a component based upon processing text and a second component based upon processing symbolic information. The Purdue Spatial Visualization Test was composed of a component based upon one-step processing and a second component based upon two-step processing of information. Student ability to determine the slope in a kinematics graph was significantly correlated with spatial ability, logical thinking, and mathematics aptitude and achievement. However, student ability to determine the area in a kinematics graph was only significantly correlated with student pre-calculus semester 2 grades. Male students performed significantly better than female students on the slope items of TUG-K. Also, male students performed significantly better than female students on the PSAT mathematics assessment and spatial ability. This study found that students have different levels of spatial ability, logical thinking, and mathematics aptitude and achievement levels. These different levels were related to student learning of kinematics and they need to be considered when kinematics is being taught. It might be easier for students to understand the kinematics graphs if curriculum developers include more activities related to spatial ability and logical thinking.

2013-12-01

To estimate the prevalence of myopia based on reduced unaided visual acuity (VA) in Chinese school children over the past 20 years. Guangzhou school health authorities have measured VA on Grade 1-12 students from 1988 to 2007 annually, using a LogMAR tumbling E chart. VA is reported as Snellen categories: normal (VA ≥ 6/6), mildly reduced (6/9 < VA <6/6), moderately reduced (6/18 < VA ≤ 6/9), and severely reduced VA (VA ≤ 6/18). In 1988, over 80% of children in Grade 1 (age 6 years) and about 30% in Grade 12 (age 17 years) had normal unaided VA. By 2007, this dropped to only 60% in Grade 1 and about 10% in Grade 12. Conversely, the prevalence of moderately and severely reduced unaided VA increased from 6.2% in Grade 1 and 62.5% in Grade 12 in 1988 to 14.5% in Grade 1 and 84.11% in Grade 12 in 2007. This rate was unchanged from 2003 to 2007 at both the Grade 1 and Grade 12 levels. In Guangzhou, the prevalence of reduced unaided VA has increased markedly in the past 20 years, but has stabilized in the past few years. This increase may result from environmental changes, such as increased schooling intensity and urbanization.

Nelemans, Stefanie A; Hale, William W; Branje, Susan J T; Meeus, Wim H J; Rudolph, Karen D

2017-11-21

This study examined the impact of the middle school transition on general anxiety trajectories from middle childhood to middle adolescence, as well as how youths' individual vulnerability and exposure to contextual stressors were associated with anxiety trajectories. Participants were 631 youth (47% boys, M age = 7.96 years at Time 1), followed for 7 successive years from second to eighth grade. Teachers reported on youths' individual vulnerability to anxiety (anxious solitude) in second grade; youth reported on their anxiety in second to eighth grade and aspects of their social contexts particularly relevant to the school transition (school hassles, peer victimization, parent-child relationship quality, and friendship quality) in sixth to eighth grade. The results revealed two subgroups that showed either strongly increasing (5%) or decreasing (14%) levels of anxiety across the transition and two subgroups with fairly stable levels of either high (11%) or low (70%) anxiety over time. Youth in the latter two subgroups could be distinguished based on their individual vulnerability to anxiety, whereas youth with increasing anxiety reported more contextual stressors and less contextual support than youth with decreasing anxiety. In sum, findings suggest that the middle school transition has the potential to alter developmental trajectories of anxiety for some youth, for better or for worse.

Lin, Che; Chen, Li-Sheng; Kuo, Shou-Jen; Chen, Dar-Ren

2014-02-01

Currently there is a debate regarding whether tamoxifen used in breast cancer has an impact on lipid profiles. The aim of this study was to determine whether tamoxifen has an impact on the serum lipid profile in Taiwanese women. Data of 109 patients were collected from the routine clinical follow-up for women with hormone receptor-positive breast cancer who were treated between July 2005 and March 2008. These patients were divided into 2 subgroups, based on their tumor grade and lymph node status. Subgroup 1 patients had tumor grade I/II and a negative lymph node status. Those patients with tumor grade III or a positive lymph node status were defined as subgroup 2. In the 109 patients, the mean serum total cholesterol (TC) levels after tamoxifen treatment, as well as the serum low-density lipoprotein cholesterol (LDL-C) levels, were lower than the baseline levels, with statistically significant differences. Treatment with tamoxifen lowered the serum TC and LDL-C levels in both subgroups. The results indicate that tamoxifen has an impact on the serum lipid profile of breast cancer patients in Taiwan. Physicians should follow up the lipid profile in these patients.

This paper introduces new longitudinal network data from the “Promoting School-Community-University Partnerships to Enhance Resilience” or “PROSPER” peers project. In 28 communities, grade-level sociometric friendship nominations were collected from two cohorts of middle school students as they moved from 6th, to 9th grade. As an illustration and description of these longitudinal network data, this paper describes the school popularity structure, changes in popularity position, and suggests linkages between popularity trajectory and substance use. In the cross-section, we find that the network is consistent with a hierarchical social organization, but exhibits considerable relational change in both particular friends and position at the individual level. We find that both the base level of popularity and the variability of popularity trajectories effect substance use. PMID:21765588

2008-03-01

Grading diabetic retinopathy in clinical trials is frequently based on 7-field stereo photography of the fundus in diagnostic mydriasis. In terms of image quality, the FF450(plus) camera (Carl Zeiss Meditec AG, Jena, Germany) defines a high-quality reference. The aim of the study was to investigate if the fully digital fundus camera Visucam(PRO NM) could serve as an alternative in clinical trials requiring 7-field stereo photography. A total of 128 eyes of diabetes patients were enrolled in the randomized, controlled, prospective trial. Seven-field stereo photography was performed with the Visucam(PRO NM) and the FF450(plus) camera, in random order, both in diagnostic mydriasis. The resulting 256 image sets from the two camera systems were graded for retinopathy levels and image quality (on a scale of 1-5); both were anonymized and blinded to the image source. On FF450(plus) stereoscopic imaging, 20% of the patients had no or mild diabetic retinopathy (ETDRS level < or = 20) and 29% had no macular oedema. No patient had to be excluded as a result of image quality. Retinopathy level did not influence the quality of grading or of images. Excellent overall correspondence was obtained between the two fundus cameras regarding retinopathy levels (kappa 0.87) and macular oedema (kappa 0.80). In diagnostic mydriasis the image quality of the Visucam was graded slightly as better than that of the FF450(plus) (2.20 versus 2.41; p < 0.001), especially for pupils < 7 mm in mydriasis. The non-mydriatic Visucam(PRO NM) offers good image quality and is suitable as a more cost-efficient and easy-to-operate camera for applications and clinical trials requiring 7-field stereo photography.

To determine grade 12 academic performance for children with inflammatory bowel disease (IBD). Children diagnosed with IBD at age<17 years identified from the population-based University of Manitoba IBD Epidemiology Database were matched by age-, sex-, and area of residence to 10 randomly selected controls. Grade 12 educational outcomes (scores on the provincial grade 12 language arts and mathematics standards tests, and enrollment-in-grade-12-by- age-17) were determined by linkage to the province wide Manitoba Education Database. Linear and logistic regression analysis were used to compare the educational outcomes, adjusting for socioeconomic status and comorbidities and evaluate predictors of educational outcomes among children with IBD. Grade 12 educational outcomes among 337 children with IBD were compared with 3093 without IBD. There were no significant differences among the 2 groups in the standardized scores (language arts: P=.31; mathematics: P=.48) or enrollment-in-grade-12-by- age-17 (P=.25). Lower socioeconomic status and diagnosis with mental health problems 6 months prior to and 6 months post-IBD diagnosis were independent predictors of worse educational outcomes. There was no significant effect of age of diagnosis of IBD, type of IBD (ulcerative colitis vs Crohn's disease), use of corticosteroids or immunomodulator agents, hospitalizations, or surgery for IBD. Children with IBD on average achieve similar levels of academic achievement in grade 12 as those without IBD. This study underscores the educational impact of mental health conditions at IBD diagnosis among children. Copyright © 2015 Elsevier Inc. All rights reserved.

A comparative study on undergraduate students' academic motivation and academic self-concept.

PubMed

Isiksal, Mine

2010-11-01

The purpose of this study was to investigate Turkish and American undergraduate students' academic motivation and academic self-concept scores regarding the years that they spent in university. The analysis was based on 566 (284 Turkish, 282 American) undergraduate students where, Academic Motivation Scale and Academic Self-Concept Scale were used as measuring instruments. The results showed that there was a statistical significant effect of nationality and number of years spent in university on undergraduate students' intrinsic motivation, extrinsic motivation, and self-concept scores. Turkish students had higher intrinsic scores whereas American students had higher extrinsic scores and more positive academic-self concept compared to Turkish partners. Regarding grade level, senior students from both cultures had higher intrinsic motivation and academic self-concept scores compared to other grade levels. In terms of extrinsic motivation, there is steady decline in American students' scores as grade level increases. On the other hand, Turkish undergraduates' extrinsic scores decrease in the second year but increase in the third and fourth year of university education. Results were discussed by taking into consideration the social and cultural differences between two nations.

Student achievement in science and mathematics on campuses that have implemented the CSCOPE curriculum model

NASA Astrophysics Data System (ADS)

Wilson, Emily R.

The purpose of this study was to determine whether differences in student achievement exist between school campuses which followed a specific standards-based curriculum model (CSCOPE) and school campuses which followed a non-CSCOPE or traditional curriculum model. One-hundred and sixty CSCOPE curriculum campuses and 160 non-CSCOPE curriculum campuses were used in the study. Achievement data were collected on students in the fifth, eighth, and eleventh grades using the campuses percentage passing on the Texas Assessment of Knowledge and Skills (TAKS) for both science and mathematics. The TAKS is the state-mandated assessment system used to comply with federal testing guidelines. Data for the 2007-2008 school year were used for the elementary level while data from 2006-2007 and 2007-2008 were used for junior high (middle school) and high school levels. Data were analyzed by overall class as well as aggregated by ethnic classifications. Descriptive statistics were used to summarize achievement results and t-tests were utilized to analyze achievement differences between the two curriculum models. Overall fifth grade students in CSCOPE schools outperformed (p < .05) non-CSCOPE counterparts in science and mathematics. Also, fifth grade Hispanic students using CSCOPE curriculum scored higher (p < .05) than those in traditional curricula. Eighth grade students in CSCOPE schools performed better (p < .05) in science than students in non-CSCOPE schools. Finally, eighth grade Hispanic and White subgroups using CSCOPE curriculum outperformed ( p < .05) their ethnic counterparts using traditional curriculum models. The only statistically significant finding at the eleventh grade level was the African-American subgroup in science, but this subgroup had too small of a sample to infer the findings to the population. Thus, the results would tend to support use of the standardized curriculum model (CSCOPE) at lower levels whereas achievement in high school may not be differentially affected by the standardized model.

HER2 over-expressing high grade endometrial cancer expresses high levels of p95HER2 variant.

Subsets of high grade endometrial cancer (EnCa) over-express HER2 (ERBB2), yet clinical trials have failed to demonstrate any anti-tumor activity utilizing trastuzumab, an approved platform for HER2 positive breast cancer (BrCa). A truncated p95HER2 variant lacking the trastuzumab binding site may confer resistance. The objective of this investigation was to characterize the expression of the p95HER2 truncated variant in EnCa. With institutional approval, 86 high grade EnCa tumors were identified with tumor specimens from surgeries performed between 2000 and 2011. Clinical data were collected and all specimens underwent tumor genotyping, HER2 immunohistochemistry (IHC, HercepTest®), HER2 fluorescent in situ hybridization (FISH), along with total HER2 (H2T) and p95HER2 assessment with VeraTag® testing. Regression models were used to compare a cohort of 86 breast tumors selected for equivalent HER2 protein expression. We identified 44 high grade endometrioid and 42 uterine serous carcinomas (USC). IHC identified high HER2 expression (2+ or 3+) in 59% of the tumors. HER2 gene amplification was observed in 16 tumors (12 USC, 4 endometrioid). Both HER2 gene amplification and protein expression correlated with H2T values. High p95HER2 expression above 2.8RF/mm2 was observed in 53% (n=54) with significant correlation with H2T levels. When matched to a cohort of 107 breast tumors based on HercepTest HER2 expression, high grade EnCa presented with higher p95 levels (p<0.001). These data demonstrate that compared to BrCa, high grade EnCa expresses higher levels of p95HER2 possibly providing rationale for the trastuzumab resistance observed in EnCa.

Adverse events are detected by monitoring the patient's status, including blood test results. However, it is difficult to identify all adverse events based on recognition by individual doctors. We developed a system that can be used to detect hematotoxicity adverse events according to blood test results recorded in an electronic medical record system. The blood test results were graded based on Common Terminology Criteria for Adverse Events (CTCAE) and changes in the blood test results (Up, Down, Flat) were assessed according to the variation in the grade. The changes in the blood test and injection data were stored in a database. By comparing the date of injection and start and end dates of the change in the blood test results, adverse events related to a designated drug were detected. Using this method, we searched for the occurrence of serious adverse events (CTCAE Grades 3 or 4) concerning WBC, ALT and creatinine related to paclitaxel at Osaka University Hospital. The rate of occurrence of a decreased WBC count, increased ALT level and increased creatinine level was 36.0%, 0.6% and 0.4%, respectively. This method is useful for detecting and estimating the rate of occurrence of hematotoxicity adverse drug events.

Problem Based Learning and the scientific process

NASA Astrophysics Data System (ADS)

Schuchardt, Daniel Shaner

This research project was developed to inspire students to constructively use problem based learning and the scientific process to learn middle school science content. The student population in this study consisted of male and female seventh grade students. Students were presented with authentic problems that are connected to physical and chemical properties of matter. The intent of the study was to have students use the scientific process of looking at existing knowledge, generating learning issues or questions about the problems, and then developing a course of action to research and design experiments to model resolutions to the authentic problems. It was expected that students would improve their ability to actively engage with others in a problem solving process to achieve a deeper understanding of Michigan's 7th Grade Level Content Expectations, the Next Generation Science Standards, and a scientific process. Problem based learning was statistically effective in students' learning of the scientific process. Students statistically showed improvement on pre to posttest scores. The teaching method of Problem Based Learning was effective for seventh grade science students at Dowagiac Middle School.

It is recommended that health-related materials for patients be written at sixth grade level or below. Many websites oriented toward patient education about dental implants are available, but the readability of these sites has not been evaluated. To assess readability of patient-oriented online information on dental implants. Websites containing patient-oriented information on dental implants were retrieved using the Google search engine. Individual and mean readability/grade levels were calculated using standardized formulas. Readability of each website was classified as easy (≤ 6th-grade level) or difficult (≥ 10th grade level). Thirty nine websites with patient-oriented information on dental implant were found. The average readability grade level of these websites was 11.65 ± 1.36. No website scored at/below the recommended 6th grade level. Thirty four of 39 websites (87.18%) were difficult to read. The number of characters, words, and sentences on these sites varied widely. All patient-oriented websites on dental implants scored above the recommended grade level, and majority of these sites were "difficult" in their readability. There is a dire need to create patient information websites on implants, which the majority can read. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The Attitudinal and Cognitive Effects of Planetarium Integration in Teaching Selected Astronomical Concepts to Fourth, Fifth, and Sixth-Grade Students

Twiest, Mark Gilbert

The purpose of this study was to investigate the attitudinal and cognitive differences among students in an astronomy curriculum which utilizes a planetarium in comparison to an astronomy curriculum which is presented solely in the classroom. The specific attitudes of interest in this study are those student attitudes toward science as a whole and toward astronomy in particular. Researcher developed attitude and astronomy achievement measures were developed and administered to 423 fourth, fifth, and sixth grade students in three schools. Pre and post test data were collected from students in this quasi-experimental design. Two way analysis of covariance techniques were used to analyze the independent variables of gender and treatment. Results revealed significant differences (p < .05) in student attitudes toward astronomy in the fourth grade favoring the control school students. No other significant differences in student attitudes were found with respect to treatment or gender. Achievement was analyzed at both the knowledge and comprehension levels. Significant differences (p <.05) in student achievement were found fourth and fifth grades with respect to knowledge level questions. In both instances these differences favored the control school setting. Significant differences (p <.05) in student achievement were found for comprehension level questions at every grade level. In this case the control school outperformed the experimental setting in the fourth and sixth grades. Fifth grade experimental setting students had significantly higher achievement on comprehension level questions. A significant interaction occurred between treatment and gender with respect to student attitudes toward astronomy in the fifth grade. A second significant interaction occurred between treatment and gender for knowledge level questions for sixth grade students. No other significant interactions were found between treatment and gender. Correlations between post test attitudes and achievement were also calculated for each grade level in both the control and experimental settings. Correlations remained below.2 in every instance except one. Post test correlations between attitudes overall and achievement in the control school's sixth grade were.54.

Harada, Hideyuki, E-mail: h.harada@scchr.jp; Seto, Takashi; Igawa, Satoshi

Purpose: To investigate the safety and efficacy of concurrent vinorelbine and thoracic radiotherapy in elderly patients with locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Eligible patients were 71 years of age or older with unresectable Stage III NSCLC. Patients were treated with thoracic radiotherapy (60 Gy) and concurrent vinorelbine (20 mg/m{sup 2} in Level 1 and 25 mg/m{sup 2} in Level 2) on Days 1 and 8 every 3 weeks for two cycles, followed by adjuvant vinorelbine (25 mg/m{sup 2}) on Days 1 and 8 every 3 weeks for two cycles. Results: Four patients were enrolled at Levelmore » 1. One patient experienced Grade 3 febrile neutropenia at Level 1 and the dose was escalated to Level 2. At Level 2, 2 of 6 patients experienced dose-limiting toxicities (Grade 4 neutropenia in 1 patient and Grade 3 infection in another). Three of 6 patients developed late Grade 2 or 3 pneumonitis. Therefore, the dose was de-escalated to Level 1. An additional 6 patients were enrolled at Level 1, 4 of whom experienced dose-limiting toxicities (incomplete radiotherapy because of Grade 2 pneumonitis in 1 patient and Grade 3 infection in 1, Grade 3 febrile neutropenia in 1, and Grade 3 esophagitis in 1). Moreover, late Grade 3 pneumothorax and Grade 5 pneumonitis occurred in 1 and 1 patient, respectively. Overall, Grade 2, 3 and 5 pneumonitis occurred in 3, 3, and 1 among 16 patients, respectively. Conclusions: Concurrent vinorelbine and thoracic radiotherapy resulted in a high incidence of severe pneumonitis when the standard dose of this agent was used for elderly patients. We therefore recommend caution in the use of this regimen and schedule for elderly patients.« less

Following the findings of the National Lung Screening Trial, several national societies from multiple disciplines have endorsed the use of low-dose chest CT to screen for lung cancer. Online patient education materials are an important tool to disseminate information to the general public regarding the proven health benefits of lung cancer screening. This study aims to evaluate the reading level at which these materials related to lung cancer screening are written. The four terms "pulmonary nodule," "radiation," "low-dose CT," and "lung cancer screening" were searched on Google, and the first 20 online resources for each term were downloaded, converted into plain text, and analyzed using 10 well-established readability scales. If the websites were not written specifically for patients, they were excluded. The 80 articles were written at a 12.6 ± 2.7 (mean ± SD) grade level, with grade levels ranging from 4.0 to 19.0. Of the 80 articles, 62.5% required a high school education to comprehend, and 22.6% required a college degree or higher (≥ 16th grade) to comprehend. Only 2.5% of the analyzed articles adhered to the recommendations of the National Institutes of Health and American Medical Association that patient education materials be written at a 3rd- to 7th-grade reading level. Commonly visited online lung cancer screening-related patient education materials are written at a level beyond the general patient population's ability to comprehend and may be contributing to a knowledge gap that is inhibiting patients from improving their health literacy.

There is a growing literature base on child and adolescent anxiety. Cross-cultural research on child and adolescent anxiety, however, has been relatively limited. This study examined whether there were similarities and differences in the self reported anxieties in Mainland Chinese and Singapore Chinese adolescents (12-17 years of age), and whether these similarities or differences were related to gender and/or grade. This study also compared anxiety levels of Mainland Chinese and Singapore Chinese adolescents with the American normative sample (12-17 years of age). The results indicate that the levels of anxieties did not differ based on country (China and Singapore). Gender differences were evident. Gender and grade interaction effects were found on the anxiety scales. Mixed results were found when comparing Mainland Chinese and Singapore Chinese with the American normative sample on the different anxiety scales.

Serum VEGF-A concentrations in patients with central nervous system (CNS) tumors

PubMed Central

2018-01-01

Angiogenesis plays an essential role in tumors development. In case of central nervous system tumors, the most important role in this process plays VEGF-A. The purpose of this study was to determine the plasma concentration of this agent in patients treated surgically because of intracranial tumors. The study involved 48 adult patients, both sexes, treated surgically because of a brain tumor. The control group consisted of 50 adult volunteers of both sexes, without cancer diagnosis. Based on the studies, it was found that serum VEGF-A levels before surgery are higher in patients with central nervous system tumors (10.39–150.57 pg/ml, median 41.70 pg/ml) than in non-cancer patients (0.00–130.77 pg/ml, median 22.56 pg/ml). The association between serum VEGF-A level and malignancy and histological type of intracranial tumor has not beed confirmed. The highest average preoperative serum VEGF-A level was found in patients with low grade gliomas, slightly lower (close to each other) in those with high grade gliomas and meningiomas, while the lowest level was characteristic for metastatic tumors. High variation in results was observed in patients with low grade gliomas (52.56 pg/ml)—higher than those reported in patients with high grade gliomas (32.38 pg/ml). In the rest types of tumors the differentiation was similar and oscillated within 23.08–27.50 pg/ml. PMID:29590109

2013-06-01

We sought to assess the readability levels of arthroscopy-related patient education materials available on the Web sites of the American Academy of Orthopaedic Surgeons (AAOS) and the Arthroscopy Association of North America (AANA). We identified all articles related to arthroscopy available in 2012 from the online patient education libraries of AAOS and AANA. After performing follow-up editing, we assessed each article with the Flesch-Kincaid (FK) readability test. Mean readability levels of the articles from the AAOS Web site and the AANA Web site were compared. We also determined the number of articles with readability levels at or below the eighth-grade level (the average reading ability of the US adult population) and sixth-grade level (the widely recommended level for patient education materials). Intraobserver reliability and interobserver reliability of FK grade assessment were evaluated. A total of 62 articles were reviewed (43 from AAOS and 19 from AANA). The mean overall FK grade level was 10.2 (range, 5.2 to 12). The AAOS articles had a mean FK grade level of 9.6 (range, 5.2 to 12), whereas the AANA articles had a mean FK grade level of 11.4 (range, 8.7 to 12); the difference was significant (P < .0001). Only 3 articles had a readability level at or below the eighth-grade level and only 1 was at or below the sixth-grade level; all were from AAOS. Intraobserver reliability and interobserver reliability were excellent (intraclass correlation coefficient of 1 for both). Online patient education materials related to arthroscopy from AAOS and AANA may be written at a level too difficult for a large portion of the patient population to comprehend.

2016-02-01

To evaluate the efficacy and safety profile of carbomer-based lipid-containing artificial tear formulations (CBLAT) in patients with dry eye syndrome. A multicenter parallel-group study was conducted in 412 patients with dry eye syndrome. Of these patients, 221 switched from using artificial tears to CBLAT (switching group) and 191 added CBLAT to their current treatment (add-on group). Ocular symptom scores, ocular staining grades, tear film breakup time (tBUT), Schirmer I test value, and Korean dry eye level (as defined by the Korean Corneal Disease Study Group guidelines) were evaluated at baseline and after 4 weeks of treatment. After 4 weeks of treatment, ocular surface staining grade, tBUT, Schirmer I value, ocular irritation symptom scores, and the positive rate of visual symptom improved significantly in both groups. Mean reductions in ocular surface staining grades (-0.8 ± 0.9) and ocular irritation symptom scores (-0.8 ± 0.8) in the add-on group were significantly higher than those (-0.5 ± 0.8 and -0.6 ± 0.8) in the switching group (P < 0.01 and P < 0.05). The positive rate of visual symptoms (44.2%) in the add-on group was significantly higher than that (26.4%) in the switching group (P < 0.01). The decrease of Korean dry eye level was 30.1% in the switching group and 51.6% in the add-on group. More patients in the add-on group had decreased dry eye levels than those in the switching group (P < 0.0001). CBLAT improves ocular surface staining grades, tBUT, Schirmer I values, and ocular symptoms in patients with dry eye syndrome.

The objective of this study was to determine cancer understanding among Japanese primary and secondary school students. The study design was a cross-sectional nationwide survey using a self-administered questionnaire. The prefecture with the lowest student population was set to 1, and that with the highest student population was set to 18 for elementary schools and 19 for junior high and high schools based on the ratio of the student population. In this way, 213 elementary schools, 222 junior high schools, and 208 high schools were selected from all 47 prefectures in Japan, and questionnaires were sent to each school. The questionnaire listed the names of 15 cancers and asked respondents to choose one answer from three: "Never heard of," "Heard of/Don't understand," or "Heard of/Understand." Response rates for schools were 44.1 % (n = 94) for elementary schools, 46.4 % (n = 103) for junior high schools, and 55.8 % (n = 116) for high schools. A total of 8,876 questionnaires were used for the analysis. Our survey suggests that the most commonly understood types of cancer differed by grade, with lung cancer the most commonly understood in elementary school, leukemia in junior high schools, and breast cancer in high schools. Girls tended to demonstrate greater cancer understanding than boys, with particularly large differences by gender in rates of understanding of breast and uterine cancer at each assessed grade level. Here, we examined Japanese primary and secondary school students. Marked differences in cancer recognition by grade and gender suggest that educational efforts are needed at various grade levels and gender-specific cancer education. Further, more than 50 % of students at any school level were not familiar with most cancers. It suggests that cancer education is deficient.

The present longitudinal study examined the reliability of self-reported academic grades across three phases in four subject domains for a sample of 916 high-school students. Self-reported grades were found to be highly positively correlated with actual grades in all academic subjects and across grades 9 to 11 underscoring the reliability of self-reported grades as an achievement indicator. Reliability of self-reported grades was found to differ across subject areas (e.g., mathematics self-reports more reliable than language studies), with a slight yet consistent tendency to over-report achievement levels also observed across grade levels and academic subjects. Overall, the absolute value of over- and underreporting was low and these patterns were not found to differ between mathematics and verbal subjects. In sum, study findings demonstrate the consistent predictive utility of students' self-reported achievement across grade levels and subject areas with the observed tendency to over-report academic grades and slight differences between domains nonetheless warranting consideration in future education research.

To assess the readability of online patient education materials (OPEM) related to common diseases treated by and procedures performed by interventional radiology (IR). The following websites were chosen based on their average Google search return for each IR OPEM content area examined in this study: Society of Interventional Radiology (SIR), Cardiovascular and Interventional Radiological Society of Europe (CIRSE), National Library of Medicine, RadiologyInfo, Mayo Clinic, WebMD, and Wikipedia. IR OPEM content area was assessed for the following: peripheral arterial disease, central venous catheter, varicocele, uterine artery embolization, vertebroplasty, transjugular intrahepatic portosystemic shunt, and deep vein thrombosis. The following algorithms were used to estimate and compare readability levels: Flesch-Kincaid Grade Formula, Flesch Reading Ease Score, Gunning Frequency of Gobbledygook, Simple Measure of Gobbledygook, and Coleman-Liau Index. Data were analyzed using general mixed modeling. On average, online sources that required beyond high school grade-level readability were Wikipedia (15.0), SIR (14.2), and RadiologyInfo (12.4); sources that required high school grade-level readability were CIRSE (11.3), Mayo Clinic (11.0), WebMD (10.6), and National Library of Medicine (9.0). On average, OPEM on uterine artery embolization, vertebroplasty, varicocele, and peripheral arterial disease required the highest level of readability (12.5, 12.3, 12.3, and 12.2, respectively). The IR OPEM assessed in this study were written above the recommended sixth-grade reading level and the health literacy level of the average American adult. Many patients in the general public may not have the ability to read and understand health information in IR OPEM. Copyright © 2015 SIR. Published by Elsevier Inc. All rights reserved.

To compare the diagnostic value of contrast-enhanced ultrasonography (CEUS) with contrast-enhanced computed tomography (CECT) for the detection of different grading of solid organ injuries in blunt abdominal trauma in animals. A self-made miniature tools were used as models to simulate a blunt hepatic or splenic trauma in 16 and 14 anesthetized dogs, respectively. Baseline ultrasound, CEUS and CECT were used to detect traumatic injuries of livers and spleens. The degree of injuries was determined by CEUS according to the American Association for the Surgery of Trauma (AAST) scale and the results compared with injury scale based on CECT evaluation. CEUS showed 22 hepatic injury sites in 16 animals and 17 splenic injury sites in other 14 animals. According to AAST scale, 2 grade I, 4 grade II, 3 grade III, 5 grade IV and 2 grade V hepatic lesions were present in 16 animals; 2 grade I, 4 grade II, 6 grade III and 2 grade IV splenic lesions in 14 animals. On CECT scan, 21 hepatic and 17 splenic injuries were demonstrated. According to Becker CT scaling for hepatic injury, 1 grade I, 2 grade II, 4 grade III, 5 grade IV and 2 grade V hepatic injuries were present. On the basis of Buntain spleen scaling, 2 grade I, 5 grade II, 5 grade III, 2 grade IV splenic injuries were showed. After Spearman rank correlation analysis, the agreement of CEUS with CECT on the degree of hepatic and splenic injury is 93.3% and 92.9%, respectively. CT is currently considered as the reference method for grading blunt abdominal trauma, according to experiment results, CEUS grading showed high levels of concordance with CECT. CEUS can accurately determine the degree of injury and will play an important role in clinical application.

An autostratigraphic view of the long-term dynamics of delta distributary channels: A new step forward with the grade index model

NASA Astrophysics Data System (ADS)

Naruse, H.; Muto, T.

2017-12-01

Autostratigraphy is the stratigraphy that is generated by large-scale, deterministic autogenic processes of depositional systems, based on the full recognition of non-equilibrium behavior in response to steady external forcing. Recent experimental studies to explore the effects of basin water depth on the dynamics of distributary channels have brought a new geometrical scheme, here referred to as the grade index model, which is expected to make a significant step forward for development of the autostratigraphy of river deltas. Grade index (0 ≤ Gindex ≤1) is a dimensionless number that describes how close the alluvial river is to a graded state and is given as the ratio of subaerial allocation of the supplied sediment to both subaerial and subaqueous allocation of the sediment, in the form of a function of dimensionless basin water depth (h*). The grade index model for a particular geometrical setting suggests that as h* increase toward +∞, all of dimensionless magnitudes of delta progradation rate (Rpro*), alluvial aggradation rate (Ragg*), channel migration rate (Rmig*), avulsion frequency decrease toward 0, and all of dimensionless timescales of channel shifting (τs*), recurrence of channels (τr*), channel avulsion (τA*) increase toward +∞, and also that Rpro* = Ragg* = Rmig* = fA* = (τs*)-1 = (τr*)-1 = (τA* )-1 = Gindex. This grade index model, despite its simple structure, offers deep insight into the rationale of shoreline autoretreat, a typical large-scale, deterministic autogenic process that is realized by non-equilibrium response to steady base level rise. A simple geometrical modeling leads to a finding that Ppro* = (1 - Ab*) Gindex, where Ab* is a dimensionless form of the bottom surface of the deltaic deposit (Ab) given by dividing Ab with the square of autostratigraphic length scale (Λ). As the delta grows with base level rise, Ab progressively increases and then inevitably meets an event that Ab* exceeds 1 (i.e. Ab exceeds Λ2). We also find that Pagg* = A* + (1 - Ab*) Gindex, where A* is a dimensionless horizontal area of the deltaplain (A* = A/Λ2). At the moment of autodrowning, A* becomes 0, Ab* takes a positive value larger than one, h* is infinitely large, and thus and Gindex takes a value close to zero. Thus, shoreline autoretreat and autodrowning of the delta are closely related to grade index.

In the last years there were many authors that suggest the existence of an association between different components of metabolic syndrome and various cancers. Two important components of metabolic syndrome are hyperglycemia and hyperinsulinemia. Both of them had already been linked with the increased risk of pancreatic, breast, endometrial or prostate cancer. However the correlation of the level of the glucose and insulin with various types and grades of brain tumors remains unclear. In this article we have analysed the values of plasma glucose and insulin in 267 patients, consecutively diagnosed with various types of brain tumors. Our results showed no correlation between the glycemia and brain tumor types or grades. High plasma levels of insulin were found in brain metastasis and astrocytomas while the other types of brain tumors (meningiomas and glioblastomas) had lower levels of the peptide. The levels of insulin were also higher in brain metastasis and grade 3 brain tumors when compared with grade 1, grade 2 and grade 4 brain tumors. PMID:24791202

Neuroticism and Conscientiousness as Moderators of the Relation Between Social Withdrawal and Internalizing Problems in Adolescence

PubMed Central

Smith, Kelly A.; Barstead, Matthew G.; Rubin, Kenneth H.

2016-01-01

Social withdrawal, or refraining from social interaction in the presence of peers, places adolescents at risk of developing emotional problems like anxiety and depression. The personality traits of neuroticism and conscientiousness also relate to emotional difficulties. For example, high conscientiousness predicts lower incidence of anxiety disorders and depression, while high neuroticism relates to greater likelihood of these problems. Based on these associations, socially withdrawn adolescents high in conscientiousness or low in neuroticism were expected to have lower levels of anxiety and depressive symptoms. Participants included 103 adolescents (59% female) who reported on their personality traits in 8th grade and their anxiety and depressive symptoms in 9th grade. Peer ratings of social withdrawal were collected within schools in 8th grade. A structural equation model revealed that 8th grade withdrawal positively predicted 9th grade anxiety and depressive symptoms controlling for 8th grade anxiety and depressive symptoms, but neuroticism did not. Conscientiousness moderated the relation of withdrawal with depressive symptoms but not anxiety, such that high levels of conscientiousness attenuated the association between withdrawal and depressive symptoms. This buffering effect may stem from the conceptual relation between conscientiousness and self-regulation. Conscientiousness did not, however, moderate the association between withdrawal and anxiety, which may be partly due to the role anxiety plays in driving withdrawal. Thus, a conscientious, well-regulated personality partially protects withdrawn adolescents from the increased risk of emotional difficulties. PMID:27844459

McHugh, R Kathryn; Sugarman, Dawn E; Kaufman, Julia S; Park, Sara; Weiss, Roger D; Greenfield, Shelly F

2014-01-01

Objective: Self-report measures of alcohol misuse and alcohol use disorders are valuable assessment tools for both research and clinical practice settings. However, readability is often overlooked when establishing the validity of these measures, which may result in measures written at a reading-grade level that is higher than the ability level of many potential respondents. The aim of the current study was to estimate the reading-grade level of validated measures of alcohol misuse and associated problems. Method: A total of 45 measures were identified, and reading-grade level was calculated using three validated readability formulas. Results: The majority of measures were written above the recommended reading-grade level for patient materials (5th–6th grade), with particularly poor readability for measure instructions. Conclusions: Given that many self-report alcohol misuse measures are written at a high reading-grade level, the consideration of readability is important when selecting measures for use in research and practice settings. Moreover, the development or modification of measures to target low-literacy populations may facilitate the broader applicability of these instruments. PMID:24650827

To interrogate grade II, III, and IV gliomas and characterize the critical effectors within the PI3-kinase pathway upstream and downstream of mTOR. Experimental design Tissues from 87 patients who were treated at UCSF between 1990 and 2004 were analyzed. Twenty-eight grade II, 17 grade III glioma, 26 grade IV gliomas, and 16 non-tumor brain specimens were analyzed. Protein levels were assessed by immunoblots; RNA levels were determined by polymerase chain reaction amplification. To address the multiple comparisons, first an overall analysis was done comparing the four groups using Spearman's Correlation Coefficient. Only if this analysis was statistically significant were individual pairwise comparisons done. Multiple comparison analyses revealed a significant correlation with grade for all variables examined, except phosphorylated-S6. Expression of phosphorylated-4E-BP1, phosphorylated-PKB/Akt, PTEN, TSC1, and TSC2 correlated with grade (P < 0.01 for all). We extended our analyses to ask whether decreases in TSC proteins levels were due to changes in mRNA levels, or due to changes in post-transcriptional alterations. We found significantly lower levels of TSC1 and TSC2 mRNA in GBMs than in grade II gliomas or non-tumor brain (P < 0.01). Expression levels of critical signaling molecules upstream and downstream of mTOR differ between non-tumor brain and gliomas of any grade. The single variable whose expression did not differ between non-tumor brain and gliomas was phosphorylated-S6, suggesting that other protein kinases, in addition to mTOR, contribute significantly to S6 phosphorylation. mTOR provides a rational therapeutic target in gliomas of all grades, and clinical benefit may emerge as mTOR inhibitors are combined with additional agents.

Affix Meaning Knowledge in First Through Third Grade Students.

PubMed

Apel, Kenn; Henbest, Victoria Suzanne

2016-04-01

We examined grade-level differences in 1st- through 3rd-grade students' performance on an experimenter-developed affix meaning task (AMT) and determined whether AMT performance explained unique variance in word-level reading and reading comprehension, beyond other known contributors to reading development. Forty students at each grade level completed an assessment battery that included measures of phonological awareness, receptive vocabulary, word-level reading, reading comprehension, and affix meaning knowledge. On the AMT, 1st-grade students were significantly less accurate than 2nd- and 3rd-grade students; there was no significant difference in performance between the 2nd- and 3rd-grade students. Regression analyses revealed that the AMT accounted for 8% unique variance of students' performance on word-level reading measures and 6% unique variance of students' performance on the reading comprehension measure, after age, phonological awareness, and receptive vocabulary were explained. These results provide initial information on the development of affix meaning knowledge via an explicit measure in 1st- through 3rd-grade students and demonstrate that affix meaning knowledge uniquely contributes to the development of reading abilities above other known literacy predictors. These findings provide empirical support for how students might use morphological problem solving to read unknown multimorphemic words successfully.

2015-12-01

Protein tyrosine nitration is involved in the pathogenesis of highly fatal astrocytomas, a type of brain cancer. To understand the molecular mechanisms of astrocytomas and to discover new biomarkers/therapeutic targets, we sought to identify nitroproteins in human astrocytoma tissue. Anti-nitrotyrosine immunoreaction-positive proteins from a high-grade astrocytoma tissue were detected with two-dimensional gel electrophoresis (2DGE)-based nitrotyrosine immunoblots, and identified with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Fifty-seven nitrotyrosine immunopositive protein spots were detected. A total of 870 proteins (nitrated and non-nitrated) in nitrotyrosine-immunopositive 2D gel spots were identified, and 18 nitroproteins and their 20 nitrotyrosine sites were identified with MS/MS analysis. These nitroproteins participate in multiple processes, including drug-resistance, signal transduction, cytoskeleton, transcription and translation, cell proliferation and apoptosis, immune response, phenotypic dedifferentiation, cell migration, and metastasis. Among those nitroproteins that might play a role in astrocytomas was nitro-sorcin, which is involved in drug resistance and metastasis and might play a role in the spread and treatment of an astrocytoma. Semiquantitative immune-based measurements of different sorcin expressions were found among different grades of astrocytomas relative to controls, and a semiquantitative increased nitration level in high-grade astrocytoma relative to control. Nitro-β-tubulin functions in cytoskeleton and cell migration. Semiquantitative immunoreactivity of β-tubulin showed increased expression among different grades of astrocytomas relative to controls and semiquantitatively increased nitration level in high-grade astrocytoma relative to control. Each nitroprotein was rationalized and related to the corresponding functional system to provide new insights into tyrosine nitration and its potential role in the pathogenesis of astrocytoma formation.

2015-01-01

Prospective longitudinal data from over 14,000 youth residing in 28 communities in the rural U.S. were analyzed to examine the emergence of mixed-sex friendship groups in early adolescence. Youth were surveyed on five occasions between fall of 6th grade and spring of 9th grade. At each assessment, youth reported the names of up to seven same-grade friends and described patterns of alcohol use, cigarette use and delinquency. Approximately 800 – 900 friendship groups (Mean = 10.5 members) were identified at each assessment and categorized in terms of gender composition (all-girl, mostly-girl, mixed-sex, mostly-boy, all-boy). The proportion of groups categorized as mixed-sex increased with grade level (10% in 6th grade, 22% in 9th grade), but gender-homogenous groups predominated at all grade levels (76% in 6th grade, 51% in 9th grade). Mixed-sex groups were slightly larger than all-girl groups but the same size as all-boy groups. All-girl groups had the highest levels of tightknittedness (i.e., density, reciprocity and transitivity), with mixed-sex groups having the lowest levels and all-boy groups having intermediate levels. After controlling for demographic factors, future mixed-sex group membership was predicted by lower popularity, higher levels of delinquency and lower levels of alcohol use; and mixed-sex friendship group membership was associated with increased likelihood of cigarette use. Results are partially consistent with Dunphy’s classic account of the emergence of mixed-sex groups in adolescence, but suggest that in early adolescence, mixed-sex group affiliation is significantly associated with deviant behavior and peripheral social status, not with popularity.

Mobin, Ahmad; Feng, Cindy Xin; Neudorf, Cory

2018-01-22

To examine the prevalence and predictors associated with cybervictimization among preadolescents in a community-based sample from Canada. Data were drawn from a cohort of 5783 students of grades 5-8, aged 9-14 from 109 elementary schools at the Saskatoon Health Region, Saskatchewan of Canada based on the Student Health Survey in the year of 2010-2011. Multivariate logistic regression with the generalized estimating equation was used to determine the individual and contextual factors associated with self-reported cybervictimization. Of the 5783 school children, 5611 (97.0%) responded to the question regarding cybervictimization. Among those respondents, 572 (10.2%) reported being cyberbullied at least once in the past four weeks. The students most likely to be victimized by cyberbullying were girls, students in grades 7 and 8 compared with grade 5, Aboriginal students compared to non-Aboriginal students, those who had lived part of their life outside of Canada compared with those who lived all of their life in Canada, those who reported drinking alcohol in the past, those who reported very elevated depressive symptoms, those who were traditionally bullied, those who had low self-esteem, and those who had a poor relationship with their parents. School-level variation in cyberbullying victimization is negligible. School neighbour-level deprivation is not significant after adjusting for individual-level characteristics and parent-child relationship. Our findings identified important characteristics of preadolescents with higher susceptibility to cybervictimization in a Canadian setting, which can be used to develop intervention strategies for mitigating cybervictimization among the study population.

The vast amount of information found on the internet, combined with its accessibility, makes it a widely utilized resource for Americans to find information pertaining to medical information. The field of radiology is no exception. In this paper, we assess the readability level of websites pertaining specifically to emergency radiology. Using Google, 23 terms were searched, and the top 10 results were recorded. Each link was evaluated for its readability level using a set of ten reputable readability scales. The search terms included the following: abdominal ultrasound, abdominal aortic aneurysm, aortic dissection, appendicitis, cord compression, CT abdomen, cholecystitis, CT chest, diverticulitis, ectopic pregnancy, epidural hematoma, dural venous thrombosis, head CT, MRI brain, MR angiography, MRI spine, ovarian torsion, pancreatitis, pelvic ultrasound, pneumoperitoneum, pulmonary embolism, subarachnoid hemorrhage, and subdural hematoma. Any content that was not written for patients was excluded. The 230 articles that were assessed were written, on average, at a 12.1 grade level. Only 2 of the 230 articles (1%) were written at the third to seventh grade recommended reading level set forth by the National Institutes of Health (NIH) and American Medical Association (AMA). Fifty-two percent of the 230 articles were written so as to require a minimum of a high school education (at least a 12th grade level). Additionally, 17 of the 230 articles (7.3%) were written at a level that exceeded an undergraduate education (at least a 16th grade level). The majority of websites with emergency radiology-related patient education materials are not adhering to the NIH and AMA's recommended reading levels, and it is likely that the average reader is not benefiting fully from these information outlets. With the link between health literacy and poor health outcomes, it is important to address the online content in this area of radiology, allowing for patient to more fully benefit from their online searches.

In this article, we introduce ESCOLEX, the first European Portuguese children's lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children's grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009-1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156-166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children's developmental stages.

The Center for Microbial Oceanography: Research and Education (C-MORE) is a NSF Science and Technology Center based at the University of Hawaii. The C-MORE education and outreach program offers a variety of resources and professional development opportunities for science educators, including online resources, participation in oceanography research cruises, teacher-training workshops, mini-grants to incorporate microbial oceanography-related content and activities into their classroom and, most recently, C- MORE science kits. C-MORE science kits provide hands-on classroom, field, and laboratory activities related to microbial oceanography for K-12 students. Each kit comes with complete materials and instructions, and is available free of charge to Hawaii's public school teachers. Several kits are available nationwide. C-MORE science kits cover a range of topics and technologies and are targeted at various grade levels. Here is a sampling of some available kits: 1) Marine Murder Mystery: The Case of the Missing Zooxanthellae. Students learn about the effect of climate change and other environmental threats on coral reef destruction through a murder-mystery experience. Participants also learn how to use DNA to identify a suspect. Grades levels: 3-8. 2) Statistical sampling. Students learn basic statistics through an exercise in random sampling, with applications to microbial oceanography. The laptops provided with this kit enable students to enter, analyze, and graph their data using EXCEL. Grades levels: 6-12. 3) Chlorophyll Lab. A research-quality fluorometer is used to measure the chlorophyll content in marine and freshwater systems. This enables students to compare biomass concentrations in samples collected from various locations. Grades levels: 9-12. 4) Conductivity-Temperature-Depth (CTD). Students predict how certain variables (e.g., temperature, pressure, chlorophyll, oxygen) vary with depth. A CTD, attached to a laptop computer, is deployed into deep water off a dock or a ship to collect real-time data and test their hypotheses. Grades levels: 9-12.

Scientific Investigations of Elementary School Children

2014-02-01

The study provides evidence concerning elementary school children's ability to conduct a scientific investigation. Two hundred and fifty sixth-grade students and 248 fourth-grade students were administered a test, and based on their performance, they were classified into high-ability and low-ability students. The sample of this study was randomly selected and included 80 students, 40 fourth-grade and 40 sixth-grade students of low and high abilities. Students were specifically instructed to investigate the functioning of a device, to think aloud prior and after any experiment with the device, and to keep a record of their experimental results. The results showed that students were inclined to mainly collect evidence from the experimental space and failed to control variables during their investigation. The majority of the students had difficulties with effectively organizing collected data and failed to coordinate hypotheses with evidence. The significant interaction effect that was found between grade level and ability in terms of students' investigation ability indicates that the existing gap between high- and low-ability students becomes bigger as students become older. Undoubtedly, ongoing research efforts for identifying patterns of children's cognitive development will be most valuable as they can have important implications for the design of teaching scenarios and inquiry-based science activities conducive to accelerating students' cognitive growth and scientific investigation abilities.

Accurate diagnosis and grading of rejection and other pathological processes are of paramount importance to guide therapeutic interventions in patients with pancreas allograft dysfunction. A multi-disciplinary panel of pathologists, surgeons and nephrologists was convened for the purpose of developing a consensus document delineating the histopathological features for diagnosis and grading of rejection in pancreas transplant biopsies. Based on the available published data and the collective experience, criteria for the diagnosis of acute cell-mediated allograft rejection (ACMR) were established. Three severity grades (I/mild, II/moderate and III/severe) were defined based on lesions known to be more or less responsive to treatment and associated with better- or worse-graft outcomes, respectively. The features of chronic rejection/graft sclerosis were reassessed, and three histological stages were established. Tentative criteria for the diagnosis of antibody-mediated rejection were also characterized, in anticipation of future studies that ought to provide more information on this process. Criteria for needle core biopsy adequacy and guidelines for pathology reporting were also defined. The availability of a simple, reproducible, clinically relevant and internationally accepted schema for grading rejection should improve the level of diagnostic accuracy and facilitate communication between all parties involved in the care of pancreas transplant recipients.

Pelvic inflammatory disease (PID) is commonly encountered in clinical practice. To provide up-to-date guidelines on management of PID. An initial search of the Cochrane database, PubMed, and Embase was performed using keywords related to PID to identify reports in any language published between January 1990 and January 2012, with an update in May 2015. All identified reports relevant to the areas of focus were included. A level of evidence based on the quality of the data available was applied for each area of focus and used for the guidelines. PID must be suspected when spontaneous pelvic pain is associated with induced adnexal or uterine pain (grade C). Pelvic ultrasonography is necessary to exclude tubo-ovarian abscess (grade B). Microbiological diagnosis requires vaginal and endocervical sampling for molecular and bacteriological analysis (grade B). First-line treatment for uncomplicated PID combines ofloxacin and metronidazole for 14days (grade B). Treatment of tubo-ovarian abscess is based on drainage if the collection measures more than 3cm (grade B), with combined ceftriaxone, metronidazole, and doxycycline for 14-21days. Current management of PID requires easily reproducible investigations and treatment, and thus can be applied worldwide. Copyright © 2016 International Federation of Gynecology and Obstetrics.

Development and validation of an energy-balance knowledge test for fourth- and fifth-grade students.

PubMed

Chen, Senlin; Zhu, Xihe; Kang, Minsoo

2017-05-01

A valid test measuring children's energy-balance (EB) knowledge is lacking in research. This study developed and validated the energy-balance knowledge test (EBKT) for fourth and fifth grade students. The original EBKT contained 25 items but was reduced to 23 items based on pilot result and intensive expert panel discussion. De-identified data were collected from 468 fourth and fifth grade students enrolled in four schools to examine the psychometric properties of the EBKT items. The Rasch model analysis was conducted using the Winstep 3.65.0 software. Differential item functioning (DIF) analysis flagged 1 item (item #4) functioning differently between boys and girls, which was deleted. The final 22-item EBKT showed desirable model-data fit indices. The items had large variability ranging from -3.58 logit (item #10, the easiest) to 1.70 logit (item #3, the hardest). The average person ability on the test was 0.28 logit (SD = .78). Additional analyses supported known-group difference validity of the EBKT scores in capturing gender- and grade-based ability differences. The test was overall valid but could be further improved by expanding test items to discern various ability levels. For lack of a better test, researchers and practitioners may use the EBKT to assess fourth- and fifth-grade students' EB knowledge.

Surgical management of morbidity due to lymphatic filariasis: the usefulness of a standardized international clinical classification of hydroceles.

PubMed

Capuano, G P; Capuano, C

2012-03-01

The objective of this work is to evaluate the usefulness of a standardized clinical classification of hydroceles in lymphatic filariasis endemic countries to guide their surgical management. 64 patients with hydroceles were operated in 2009-2010, in Level II hospitals (WHO classification), during two visits to Fiji, by the same mobile surgical team. The number of hydroceles treated was 83. We developed and evaluated a much needed clinical classification of hydroceles based on four criteria: Type (uni/bilateral); Side (left/right); Stage of enlargement of the scrotum rated from I to VI; Grade of burial of the penis rated from 0 to 4. It lead to the conclusion that 1) A Stage I or II hydrocele, associated with Grade 0 or 1 penis burial could be considered a "Simple Hydrocele". The surgical treatment is simple with no anticipated early complication. WHO Level II of health care structure seems adapted. 2) A Stage III or IV hydrocele associated with Grade 2, 3 or 4 penis burial could be considered a "Complicated Hydrocele". The operation is longer, more complicated and the possibility of occurrence of complications seems greater. A level III health care facility would be more adapted under the normal functioning of the health system. We conclude that a standardized clinical classification of hydroceles based on the Stage of enlargement of the scrotum and the Grade of burial of the penis appears to be a useful tool to guide the decision about the level of care and the surgical technique required. We use the same classification for penoscrotal lymphoedema. A decision tree is presented for the management of hydroceles in lymphatic filariasis endemic countries which could usefully complement the "Algorithm for management of scrotal swelling" proposed by WHO in 2002. An international classification system of hydroceles would also allow standardization and facilitate study design and comparisons of their results.

For health information technology tools to fully inform evidence-based decisions, recommendations must be reliably assessed for quality and strength of evidence. We aimed to create an annotation framework for grading recommendations regarding appropriate use of diagnostic imaging examinations. The annotation framework was created by an expert panel (clinicians in three medical specialties, medical librarians, and biomedical scientists) who developed a process for achieving consensus in assessing recommendations, and evaluated by measuring agreement in grading the strength of evidence for 120 empirically selected recommendations using the Oxford Levels of Evidence. Eighty-two percent of recommendations were assigned to Level 5 (expert opinion). Inter-annotator agreement was 0.70 on initial grading (κ = 0.35, 95% CI, 0.23-0.48). After systematic discussion utilizing the annotation framework, agreement increased significantly to 0.97 (κ = 0.88, 95% CI, 0.77-0.99). A novel annotation framework was effective for grading the strength of evidence supporting appropriate use criteria for diagnostic imaging exams. © The Author 2016.

To explore the correlations of the expression of mutant isocitrate dehydrogenase (IDH1) (R132H) protein with angiogenesis and cell proliferation in glioma. We performed polymerase chain reaction-based IDH gene mutation screening in 385 glioma samples, and the subcellular localization and expression levels of IDH1 (R132H) was examined by immunohistochemistry (IHC). Ki-67 labeling index was introduced to determine the proliferation of glioma cells, and the microvessel density was measured through CD34 staining. Statistical analyses were performed to show the correlations of IDH1 mutation with cell proliferation and microvessel density. The mutant rates of IDH1 were about 50%-60% in grade II-III gliomas and secondary glioblastomas, which were significantly higher than those in pilocytic astrocytoma (grade I) and primary glioblastoma (grade IV). Moreover, the level of IDH1 (R132H) protein was positively correlated with Ki-67 labeling index and microvessel density. IDH mutation was common in grade II-III glioma and secondary glioblastoma, and the mutant IDH1 (R132H) might play a critical role in the cell proliferation and angiogenesis of glioma.

Severity of emergency general surgery (EGS) diseases has not been standardized until recently. The American Association for the Surgery of Trauma (AAST) proposed an anatomic severity grading system for EGS diseases to facilitate communication and quality comparisons between providers and hospitals. Previous work has demonstrated validity of the system for appendicitis in the United States. To demonstrate generalizability, we aim to externally validate this grading system in South African patients with appendicitis. Patients with acute appendicitis during 2010 to 2016 were identified at multi-institutional sites within South Africa. Baseline demographics and procedure types were recorded, and AAST grades were assigned based on intraoperative findings. Outcomes included duration of stay, mortality, and Clavien-Dindo complications. Summary statistical univariate and nominal logistic regression analyses were performed to compare AAST grade and outcomes. A total of 1,415 patients with a median (interquartile range) age of 19 years (14-28 years) were included (55% men). One hundred percent underwent appendectomy: 63.5% completed via midline laparotomy, 36.5% via limited incision (31.8% via McBurney incision and 4.7% via laparoscopy). Overall, 30-day mortality rate was 1.4% with an overall complication rate of 44%. Most common complications included surgical site infection (n = 147, 10.4%), pneumonia (n = 105, 7.4%), and renal failure (n = 64, 4.5%). Distribution of AAST grade is as follows: Grade 0 (10, 0.7%), Grade 1 (247, 17.4%), Grade 2 (280, 19.8%), Grade 3 (158, 11.3%), Grade 4 (179, 12.6%), and Grade 5 (541, 38.2%). Increased median (interquartile range) AAST grades were recorded in patients with complications, 5 (3-5) compared with those without (2 [1-3], p = 0.001). Duration of stay was increased for patients with higher AAST grades: 4 and 5 (10.6 ± 5.9 days) versus I and II (3.6 ± 4.3 days; p = 0.001). Area under the receiver operating characteristic analysis to predict presence of any complication based on AAST grade was 0.90. The AAST EGS grading system is valid to predict important clinical outcomes in a South African population with an increased degree of severity on presentation. These results support generalizability of the AAST EGS grading system for appendicitis in a developing nation. Prognostic, level II.

Recent research suggests that the etiology of reading achievement can differ across environmental contexts. In the US, schools are commonly assigned grades (e.g. 'A', 'B') often interpreted to indicate school quality. This study explored differences in the etiology of early literacy skills for students based on these school grades. Participants included twins drawn from the Florida Twin Project on Reading (n = 1313 pairs) aged 4 to 10 years during the 2006-07 school year. Early literacy skills were assessed with DIBELS subtests: Oral Reading Fluency (ORF), Nonsense Word Fluency (NWF), Initial Sound Fluency (ISF), Letter Naming Fluency (LNF), and Phoneme Segmentation Fluency (PSF). School grade data were retrieved from the Florida Department of Education. Multi-group analyses were conducted separately for subsamples defined by 'A' or 'non-A' schools, controlling for school-level socioeconomic status. Results indicated significant etiological differences on pre-reading skills (ISF, LNF, and PSF), but not word-level reading skills (ORF and NWF). There was a consistent trend of greater environmental influences on pre-reading skills in non-A schools, arguably representing 'poorer' environmental contexts than the A schools. Importantly, this is the case outside of resources linked with school-level SES, indicating that something about the direct environment on pre-reading skills in the non-A school context is more variable than for A schools. © 2016 John Wiley & Sons Ltd.

Instructional and behavior management practices implemented by elementary general education teachers.

Reddy, Linda A; Fabiano, Gregory A; Dudek, Christopher M; Hsu, Louis

2013-12-01

This investigation examined 317 general education kindergarten through fifth-grade teachers' use of instructional and behavioral management strategies as measured by the Classroom Strategy Scale (CSS)-Observer Form, a multidimensional tool for assessing classroom practices. The CSS generates frequency of strategy use and discrepancy scores reflecting the difference between recommended and actual frequencies of strategy use. Hierarchical linear models (HLMs) suggested that teachers' grade-level assignment was related to their frequency of using instructional and behavioral management strategies: Lower grade teachers utilized more clear 1 to 2 step commands, praise statements, and behavioral corrective feedback strategies than upper grade teachers, whereas upper grade teachers utilized more academic monitoring and feedback strategies, content/concept summaries, student focused learning and engagement, and student thinking strategies than lower grade teachers. Except for the use of praise statements, teachers' usage of instructional and behavioral management strategies was not found to be related to years of teaching experience or to the interaction of years of teaching experience and grade-level assignment. HLMs suggested that teachers' grade level was related to their discrepancy scores of some instructional and behavioral management strategies: Upper grade teachers had higher discrepancy scores in academic performance feedback, behavioral feedback, and praise than lower grade teachers. Teachers' discrepancy scores of instructional and behavioral management strategies were not found to be related to years of teaching experience or to the interaction of years of teaching experience and grade-level assignment. Implications of results for school psychology practice are outlined. © 2013.

To relate subjective workload (WL) levels to errors for routine clinical tasks. Nine physicians (4 faculty and 5 residents) each performed 3 radiation therapy planning cases. The WL levels were subjectively assessed using National Aeronautics and Space Administration Task Load Index (NASA-TLX). Individual performance was assessed objectively based on the severity grade of errors. The relationship between the WL and performance was assessed via ordinal logistic regression. There was an increased rate of severity grade of errors with increasing WL (P value = .02). As the majority of the higher NASA-TLX scores, and the majority of the performance errors were in the residents, our findings are likely most pertinent to radiation oncology centers with training programs. WL levels may be an important factor contributing to errors during radiation therapy planning tasks. Published by Elsevier Inc.

Background and Aims: Nonalcoholic fatty liver disease (NAFLD) is a silent disease; its spectrum includes simple steatosis, nonalcoholic steatohepatitis and fibrosis. Pro- and anti-inflammatory cytokines play roles in the pathogenesis of NAFLD and insulin resistance (IR). Moreover, plasma cell antigen-1 (PC-1) is related to IR and associated with NAFLD progression. Therefore, we aimed to detect biomarkers, ultrasonographic and anthropometric findings capable of differentiating NAFLD grades, since most previous investigators were concerned more with NAFLD patients without classifying them into grades. Methods: A total of 87 NAFLD patients (31 with grade 1 (mild NAFLD), 26 with grade 2 (moderate NAFLD) and 30 with grade 3 (severe NAFLD) were included in the study, in addition to 47 controls (grade 0). All subjects underwent ultrasonographic examination for NAFLD diagnosis. Serum interleukin-10 (IL-10), plasma interleukin-18 (IL-18) and plasma PC-1 levels were determined using enzyme-linked immunosorbent assay. Results: Homoeostasis model assessment (HOMA)-IR was higher in different NAFLD grades than in controls. Ultrasonographic and anthropometric findings and lipid profile indices (except for high-density lipoprotein cholesterol, which was decreased) were increased with NAFLD progression. Grade 3 patients showed significant increase in levels of IL-18 and significant decrease in IL-10 and PC-1 levels when compared to grade 1 patients. Conclusion: Anthropometric and ultrasonographic findings were valuable in differentiating NAFLD grades. IR is very important in NAFLD pathogenesis. IL-18, HOMA-index and PC-1 levels could be used to differentiate between NAFLD grades, together with other measurements.

Written information is commonly used to inform patients about their disease and treatment but must be evidence-based and understandable to be useful. This study assessed the quality of the content and the readability of information brochures for people affected by brain tumours. We randomly selected 18 publicly available brochures. Brochures were assessed by criteria to assess the quality of content using the DISCERN instrument. Readability was tested using three commonly used formulas, which yield the reading grade level required to comprehend the brochure (sixth grade level recommended). The mean overall DISCERN score was 3.17 out of a maximum of 5 (moderate quality); only one achieved a rating greater than 4 (high quality). Only one brochure met the sixth grade readability criteria. Although brochures may have accurate content, few satisfied all of the recommended criteria to evaluate their content. Existing brochures need to be critically reviewed and simplified and consumer-focused brochures, produced.

Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

NASA Astrophysics Data System (ADS)

Williams, Richard L.; Yore, Larry D.

Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

Patterns of Incorrect Responses on the FCI and Course Success

NASA Astrophysics Data System (ADS)

Wells, James; Mokaya, Fridah; Valente, Diego

The Force Concept Inventory (FCI) is often used to measure the effectiveness of instructional pedagogy in introductory physics courses both at the algebra- and calculus-based level. Scores on the FCI are correlated with the performance of students in a class, as measured by their final course grade. We have collected data from several semesters of first-semester introductory mechanics courses at a public 4-year university, taught in large-scale classrooms with pedagogy including elements of Just-in-Time Teaching pedagogy along with active learning course components. The data collected includes pre- and post-test FCI scores, midterm exam grades, and final course grades. We examine whether certain patterns of incorrect answers on the FCI post-test are predictive of course grades, indicating whether certain specific student preconceptions are more detrimental than others to the success of students in an introductory mechanics course.

In 2010, under the guidance of the DGAI (German Society of Anaesthesiology and Intensive Care Medicine) and DIVI (German Interdisciplinary Association for Intensive Care and Emergency Medicine), twelve German medical societies published the "Evidence- and Consensus-based Guidelines on the Management of Analgesia, Sedation and Delirium in Intensive Care". Since then, several new studies and publications have considerably increased the body of evidence, including the new recommendations from the American College of Critical Care Medicine (ACCM) in conjunction with Society of Critical Care Medicine (SCCM) and American Society of Health-System Pharmacists (ASHP) from 2013. For this update, a major restructuring and extension of the guidelines were needed in order to cover new aspects of treatment, such as sleep and anxiety management. The literature was systematically searched and evaluated using the criteria of the Oxford Center of Evidence Based Medicine. The body of evidence used to formulate these recommendations was reviewed and approved by representatives of 17 national societies. Three grades of recommendation were used as follows: Grade "A" (strong recommendation), Grade "B" (recommendation) and Grade "0" (open recommendation). The result is a comprehensive, interdisciplinary, evidence and consensus-based set of level 3 guidelines. This publication was designed for all ICU professionals, and takes into account all critically ill patient populations. It represents a guide to symptom-oriented prevention, diagnosis, and treatment of delirium, anxiety, stress, and protocol-based analgesia, sedation, and sleep-management in intensive care medicine.

One of the goals of the AOFAS website is to provide easily understandable information about orthopaedic foot and ankle conditions to the public. However, validation of this goal has not been conducted. Evaluation of text reading level is frequently performed using the Flesch-Kincaid formula (FKF). This study evaluated whether the patient information section of the AOFAS website meets recommended readability guidelines for medical information. Seventy-nine publicly accessible entries within the patient education section of the AOFAS website were analyzed for grade level readability using the FKF. Two entries were unable to be effectively evaluated using the FKF. The average grade reading level of all patient education entries was 8.3 (95% CI 7.8 to 8.9). Only 20.8% of entries were at or below a 6th grade reading level. Almost 30% were above the 8th grade level. The average grade levels of the constituent sections were: ;;Ailments and Conditions'', 8.7; ;;Steps to Recovery'', 7.1; ;;Adult Feet'', 8.3; ;;Children's Feet'', 7.5; ;;Foot Health and Fitness'', 7.8; ;;Shoes'', 8.5; and ;;Glossary'', 10.1. The percentage of entries within these sections below a 7th grade reading level were 13%, 30%, 0%, 0%, 43%, 24% and 0%, respectively. The percentage of entries at or below the recommended 6th grade reading level on the AOFAS website compared favorably with other orthopaedic organizations' websites. However, the majority still exceeds a recommended reading level. To enhance the readability of patient education materials, we believe use of computer aided readability assessment tools should be considered in future website revisions.

Variation of student numerical and figural reasoning approaches by pattern generalization type, strategy use and grade level

El Mouhayar, Rabih; Jurdak, Murad

2016-02-01

This paper explored variation of student numerical and figural reasoning approaches across different pattern generalization types and across grade level. An instrument was designed for this purpose. The instrument was given to a sample of 1232 students from grades 4 to 11 from five schools in Lebanon. Analysis of data showed that the numerical reasoning approach seems to be more dominant than the figural reasoning approach for the near and far pattern generalization types but not for the immediate generalization type. The findings showed that for the recursive strategy, the numerical reasoning approach seems to be more dominant than the figural reasoning approach for each of the three pattern generalization types. However, the figural reasoning approach seems to be more dominant than the numerical reasoning approach for the functional strategy, for each generalization type. The findings also showed that the numerical reasoning was more dominant than the figural reasoning in lower grade levels (grades 4 and 5) for each generalization type. In contrast, the figural reasoning became more dominant than the numerical reasoning in the upper grade levels (grades 10 and 11).

In renal transplantation, serum soluble CD30 (sCD30) levels in graft recipients are associated with increased rejection and graft loss. We investigated whether pre-transplant sCD30 concentrations are predictive of the grade of rejection. Pre-transplant sera of 51 patients with tubulointerstitial rejection (TIR), 16 patients with vascular rejection (VR) and an age-matched control group of 41 patients with no rejection (NR) were analyzed for sCD30. The transplant biopsies were immunostained for C4d. The median sCD30 level was significantly elevated in the group with VR (248 Units (U)/mL, range: 92-802) when compared with TIR (103 U/mL, range: 36-309, p<0.001) and NR (179 U/mL, range: 70-343, p<0.03). Moreover, patients with TIR had significantly lower sCD30 levels compared to NR. Based on C4d staining, a TH2 driven process, the median sCD30 levels were significantly raised in C4d+ patients compared with C4d- group (177 U/mL vs. 120 U/mL, p<0.05). sCD30 levels measured at time of transplantation correlate with the grade of rejection. High pre-transplant levels are associated with antibody-mediated rejection which carries a poorer prognosis. sCD30 could be another tool to assess immunological risk prior to transplantation and enable a patient centered approach to immunosuppression.

Effects of multisensory resources on the achievement and science attitudes of seventh-grade suburban students taught science concepts on and above grade level

NASA Astrophysics Data System (ADS)

Roberts, Patrice Helen

This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual-preference effect. Furthermore, the students indicated significantly more positive attitudes when instructed with a multisensory approach on either grade-level or above-grade level science content (p < 0.0001). The findings supported using a multisensory approach when teaching science concepts that are new to and difficult for students (Martini, 1986).

Determination and reporting of disease severity in emergency general surgery lacks standardization. Recently, the American Association for the Surgery of Trauma (AAST) proposed an anatomic severity grading system. We aimed to validate this system in patients with appendicitis and determine if cross-sectional imaging correlates with disease severity at operation. Patients 18 years or older undergoing treatment for acute appendicitis between 2013 and 2015 were identified. Baseline demographics, procedure types were recorded, and AAST grades were assigned based on intraoperative and radiologic findings. Outcomes including length of stay, 30-day mortality, and complications based on Clavien-Dindo categories and National Surgical Quality Improvement Program variables. Summary statistical univariate, nominal logistic, and standard least squares analyses were performed comparing AAST grade with key outcomes. Bland-Altman analysis compared operative findings with preoperative cross-sectional imaging to compare assigning grades. Three hundred thirty-four patients with mean (±SD) age of 39.3 years (±16.5) were included (53% men), and all patients had cross-sectional imaging. Two hundred ninety-nine underwent appendectomy, and 85% completed laparoscopic. Thirty-day mortality rate was 0.9%, complication rate was 21%. Increased (median [interquartile range, IQR]) AAST grade was recorded in patients with complications (2 [1-4]) compared with those without (1 [1-1], p = 0.001). For operative management, (median [IQR]) AAST grades were significantly associated with procedure type: laparoscopic (1 [1-1]), open (4 [2-5]), conversion to open (3 [1-4], p = 0.001). Increased (median [IQR]) AAST grades were significantly associated in nonoperative management: patients having a complication had a higher median AAST grade (4 [3-5]) compared with those without (3 [2-3], p = 0.001). Bland-Altman analysis comparing AAST grade and cross-sectional imaging demonstrated no difference (-0.02 ± 0.02; p = 0.2; coefficient of repeatability 0.9). The AAST grading system is valid in our population. Increased AAST grade is associated with open procedures, complications, and length of stay. The AAST emergency general surgery grade determined by preoperative imaging strongly correlated to operative findings. Epidemiologic/prognostic study, level III.

Objective To investigate the effect of bridging defects in chronic spinal cord injury using peripheral nerve grafts combined with a chitosan-laminin scaffold and enhancing regeneration through them by co-transplantation with bone-marrow-derived mesenchymal stem cells. Methods In 14 patients with chronic paraplegia caused by spinal cord injury, cord defects were grafted and stem cells injected into the whole construct and contained using a chitosan-laminin paste. Patients were evaluated using the International Standards for Classification of Spinal Cord Injuries. Results Chitosan disintegration leading to post-operative seroma formation was a complication. Motor level improved four levels in 2 cases and two levels in 12 cases. Sensory-level improved six levels in two cases, five levels in five cases, four levels in three cases, and three levels in four cases. A four-level neurological improvement was recorded in 2 cases and a two-level neurological improvement occurred in 12 cases. The American Spinal Impairment Association (ASIA) impairment scale improved from A to C in 12 cases and from A to B in 2 cases. Although motor power improvement was recorded in the abdominal muscles (2 grades), hip flexors (3 grades), hip adductors (3 grades), knee extensors (2–3 grades), ankle dorsiflexors (1–2 grades), long toe extensors (1–2 grades), and plantar flexors (0–2 grades), this improvement was too low to enable them to stand erect and hold their knees extended while walking unaided. Conclusion Mesenchymal stem cell-derived neural stem cell-like cell transplantation enhances recovery in chronic spinal cord injuries with defects bridged by sural nerve grafts combined with a chitosan-laminin scaffold.

Some studies have demonstrated that the Cattell-Horn-Carroll (CHC) cognitive abilities influence writing; however, little research has investigated whether CHC cognitive abilities influence writing the same way for males and females across grades. We used multiple group structural equation models to investigate whether CHC cognitive ability influences on written expression differed between grades or sex using the Kaufman Assessment Battery for Children, Second Edition and the Kaufman Tests of Educational Achievement, Second Edition co-normed standardization sample data (N=2117). After testing for consistent measurement of cognitive abilities across grades and sex, we tested whether the cognitive ability influences on written expression were moderated by grade level or sex. An important developmental shift was observed equally across sex groups: Learning Efficiency (Gl) influences decreased whereas Crystallized Ability (Gc) influences increased after fourth grade. Further, Short-Term Memory (Gsm) and Retrieval Fluency (Gr) influences on written expression depended on sex at grades 1-4, with larger Gr influences for females and larger Gsm influences for males. We internally replicated our main findings using two different cognitive explanatory models, adding further support for the developmental and sex-based differential cognitive ability influences on writing. Explanatory cognitive models of writing need to incorporate development, and possibly, sex to provide an expanded understanding of writing development and guard against potential generalizability issues characteristic of special population (i.e., male-female) studies.

2015-12-01

Informed consent is a pillar of ethical medicine which requires patients to fully comprehend relevant issues including the risks, benefits, and alternatives of an intervention. Given the average reading skill of US adults is at the 8th grade level, the American Medical Association (AMA) and the National Institutes of Health (NIH) recommend patient information materials should not exceed a 6th grade reading level. We hypothesized that text provided in invasive procedure consent forms would exceed recommended readability guidelines for medical information. To test this hypothesis, we gathered procedure consent forms from all surgical inpatient hospitals in the state of Rhode Island. For each consent form, readability analysis was measured with the following measures: Flesch Reading Ease Formula, Flesch-Kincaid Grade Level, Fog Scale, SMOG Index, Coleman-Liau Index, Automated Readability Index, and Linsear Write Formula. These readability scores were used to calculate a composite Text Readability Consensus Grade Level. Invasive procedure consent forms were found to be written at an average of 15th grade level (i.e., third year of college), which is significantly higher than the average US adult reading level of 8th grade (p < 0.0001) and the AMA/NIH recommended readability guidelines for patient materials of 6th grade (p < 0.0001). Invasive procedure consent forms have readability levels which makes comprehension difficult or impossible for many patients. Efforts to improve the readability of procedural consent forms should improve patient understanding regarding their healthcare decisions. © 2015 Wiley Periodicals, Inc.

Abstract Background Informed consent is a pillar of ethical medicine which requires patients to fully comprehend relevant issues including the risks, benefits, and alternatives of an intervention. Given the average reading skill of US adults is at the 8th grade level, the American Medical Association (AMA) and the National Institutes of Health (NIH) recommend patient information materials should not exceed a 6th grade reading level. We hypothesized that text provided in invasive procedure consent forms would exceed recommended readability guidelines for medical information. Materials and methods To test this hypothesis, we gathered procedure consent forms from all surgical inpatient hospitals in the state of Rhode Island. For each consent form, readability analysis was measured with the following measures: Flesch Reading Ease Formula, Flesch–Kincaid Grade Level, Fog Scale, SMOG Index, Coleman–Liau Index, Automated Readability Index, and Linsear Write Formula. These readability scores were used to calculate a composite Text Readability Consensus Grade Level. Results Invasive procedure consent forms were found to be written at an average of 15th grade level (i.e., third year of college), which is significantly higher than the average US adult reading level of 8th grade (p < 0.0001) and the AMA/NIH recommended readability guidelines for patient materials of 6th grade (p < 0.0001). Conclusion Invasive procedure consent forms have readability levels which makes comprehension difficult or impossible for many patients. Efforts to improve the readability of procedural consent forms should improve patient understanding regarding their healthcare decisions. PMID:26678039

2015-12-01

Patients increasingly use the Internet for educational material concerning health and diseases. This information can be utilized to teach the population of hepatitis B and C if properly written at the necessary grade level of the intended patient population. We explored the readability of online resources concerning hepatitis B and C. Google searches were performed for "Hepatitis B" and "Hepatitis C." The Internet resources that were intended for patient education were used with specific exclusions. Articles were taken from 19 and 23 different websites focusing on the symptoms, diagnosis, and treatment of hepatitis B and C, respectively. The articles were analyzed using Readability Studio Professional Edition (Oleander Solutions, Vandalia, OH) using 10 different readability scales. The results were compared and averaged to identify the anticipated academic grade level required to understand the information. The average readability scores of the 10 scales had ranges of 9.7-16.4 for hepatitis B and 9.2-16.4 for hepatitis C. The average academic reading grade level for hepatitis B was 12.6 ± 2.1 and for hepatitis C was 12.7 ± 2.1. There was no significant discrepancy between the hepatitis B and C Internet resource averaged grade levels. The resources accessed by patients are higher than the previously determined necessary grade level for patients to properly understand the intended information. The American Medical Association recommends material should be simplified to grade levels below the sixth grade level to benefit the ideal proportion of the patient population.

Multivariate Assessment of Middle School Students' Interest in STEM Career: a Profile from Turkey

NASA Astrophysics Data System (ADS)

Koyunlu Ünlü, Zeynep; Dökme, İlbilge

2018-05-01

According to a report by the Turkish Industry and Business Association, Turkey will need approximately 1 million individuals to be employed in Science Technology Engineering Mathematics (STEM) fields by 2023, and 31% of this requirement will not be met. For continuous economic development, there is a need to integrate STEM into education in Turkey, which brings the need for research in this area. This study, based on a survey model, aimed to determine the level of interest of a sample of Turkish middle school students in STEM careers on the basis of gender, where they lived, grade levels, their end-of-semester grades, and their parents' educational status and levels of income. The research data was collected using the STEM Career Interest Survey (STEM-CIS) and Personal Information Form, which were applied to 851 middle school students (fifth and eighth graders). The collected data was analyzed with SPSS using Mann Whitney U and Kruskal Wallis H tests. It was found that middle school students' interest in STEM careers differed according to sex, where they lived, and grade levels but it did not differ in relation to their parents' educational status and the levels of income of the family. It is believed that the results obtained in this study reflecting the profile in Turkey will guide educational policy makers, curriculum developers, teachers, pre-service teachers, and researchers about STEM education.

Various otolaryngology associations provide Internet-based patient education material (IPEM) to the general public. However, this information may be written above the fourth- to sixth-grade reading level recommended by the American Medical Association (AMA) and National Institutes of Health (NIH). The purpose of this study was to assess the readability of otolaryngology-related IPEMs on various otolaryngology association websites and to determine whether they are above the recommended reading level for patient education materials. Analysis of patient education materials from 9 major otolaryngology association websites. The readability of 262 otolaryngology-related IPEMs was assessed with 8 numerical and 2 graphical readability tools. Averages were evaluated against national recommendations and between each source using analysis of variance (ANOVA) with post hoc Tukey's honestly significant difference (HSD) analysis. Mean readability scores for each otolaryngology association website were compared. Mean website readability scores using Flesch Reading Ease test, Flesch-Kincaid Grade Level, Coleman-Liau Index, SMOG grading, Gunning Fog Index, New Dale-Chall Readability Formula, FORCAST Formula, New Fog Count Test, Raygor Readability Estimate, and the Fry Readability Graph ranged from 20.0 to 57.8, 9.7 to 17.1, 10.7 to 15.9, 11.6 to 18.2, 10.9 to 15.0, 8.6 to 16.0, 10.4 to 12.1, 8.5 to 11.8, 10.5 to 17.0, and 10.0 to 17.0, respectively. ANOVA results indicate a significant difference (P < .05) between the websites for each individual assessment. The IPEMs found on all otolaryngology association websites exceed the recommended fourth- to sixth-grade reading level.

Study Design An Internet-based evaluation of Web sites regarding lumbar fusion. Objective The Internet has become a major resource for patients; however, the quality and readability of Internet information regarding lumbar fusion is unclear. The objective of this study is to evaluate the quality and readability of Internet information regarding lumbar fusion and to determine whether these measures changed with Web site modality, complexity of the search term, or Health on the Net Code of Conduct certification. Methods Using five search engines and three different search terms of varying complexity (“low back fusion,” “lumbar fusion,” and “lumbar arthrodesis”), we identified and reviewed 153 unique Web site hits for information quality and readability. Web sites were specifically analyzed by search term and Web site modality. Information quality was evaluated on a 5-point scale. Information readability was assessed using the Flesch-Kincaid score for reading grade level. Results The average quality score was low. The average reading grade level was nearly six grade levels above that recommended by National Work Group on Literacy and Health. The quality and readability of Internet information was significantly dependent on Web site modality. The use of more complex search terms yielded information of higher reading grade level but not higher quality. Conclusions Higher-quality information about lumbar fusion conveyed using language that is more readable by the general public is needed on the Internet. It is important for health care providers to be aware of the information accessible to patients, as it likely influences their decision making regarding care. PMID:26933614
