Language Predictors of Word-Problem Performance Among Third-Grade Students With Mathematics Difficulty.

We examined how generalized and mathematics-specific language skills predicted the word-problem performance of students with mathematics difficulty. Participants included 325 third-grade students in the southwestern United States who performed at or below the 25th percentile on a word-problem measure. We assessed generalized language skills in word reading, passage comprehension, and vocabulary knowledge.

Defining the Optimal Dose for 3-Dimensional Conformal Accelerated Partial Breast Irradiation: 15-Year Follow-Up of a Dose-Escalation Trial.

Purpose: Randomized trials have demonstrated similar local tumor control in patients treated with accelerated partial-breast irradiation (APBI) compared with whole-breast irradiation. However, the optimal APBI dose for maximizing tumor control and minimizing toxicity is uncertain.

Methods And Materials: We enrolled patients ≥18 years of age with grade 1 or 2 ductal carcinoma in situ or stage I invasive breast cancer and resection margins ≥2 mm between 2003 and 2011 to a sequential dose-escalation trial using 3-dimensional conformal external beam APBI giving twice daily 4 Gy fractions with total doses of 32 Gy, 36 Gy, and 40 Gy.

Association between dietary fructose and human colon DNA methylation: implication for racial disparities in colorectal cancer risk using a cross-sectional study.

Background: An increasing body of evidence has linked fructose intake to colorectal cancer (CRC). African American (AA) adults consume greater quantities of fructose and are more likely to develop right-side colon cancer than European American (EA) adults.

Objective: We examined the hypothesis that fructose consumption leads to epigenomic and transcriptomic differences associated with CRC tumor biology.

The HET (history, electrocardiogram, and troponin) score has low efficacy and negative predictive value in a multisite U.S. cohort study.

Introduction: The History, Electrocardiogram, and Troponin (HET) score is a simplified alternative to the HEART score for risk stratifying emergency department (ED) patients with chest pain. This study evaluates the safety and efficacy of the HET score for 30-day cardiac death or myocardial infarction (MI).

Methods: We conducted a secondary analysis of the STOP-CP multisite cohort study.

Metabolic profiling and antibacterial activity of tree wood extracts obtained under variable extraction conditions.

Introduction: Tree bacterial diseases are a threat in forestry due to their increasing incidence and severity. Understanding tree defence mechanisms requires evaluating metabolic changes arising during infection. Metabolite extraction affects the chemical diversity of the samples and, therefore, the biological relevance of the data.
