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.

Open versus robotic-assisted techniques for multivisceral pelvic resections of locally advanced or recurrent colorectal and anal cancers: short-term outcomes from a single centre.

Background: Pelvic exenterations are now established as a standard of care for locally advanced and recurrent rectal cancer. Traditionally, these radical and complex operations have been performed via an open approach, but with the increasing expertise in robotic-assisted surgery (RAS), there is scope to perform such cases robotically. This study compares outcomes from open and RAS pelvic exenterations.

Radiotherapy with cetuximab or durvalumab for locoregionally advanced head and neck cancer in patients with a contraindication to cisplatin (NRG-HN004): an open-label, multicentre, parallel-group, randomised, phase 2/3 trial.

Background: Management of patients with locoregionally advanced head and neck squamous cell carcinoma (HNSCC) when cisplatin is contraindicated is controversial. We aimed to assess whether radiotherapy with concurrent and adjuvant durvalumab would improve outcomes compared with radiotherapy with cetuximab.

Methods: NRG-HN004 was designed as an open-label, multicentre, parallel-group, randomised, phase 2/3 trial with safety lead-in conducted at 89 academic and community medical centres in North America.

Considerations for Intensifying Word-Problem Interventions for Students With MD: A Qualitative Umbrella Review of Relevant Meta-Analyses.

Word problem-solving (WPS) poses a significant challenge for many students, particularly those with mathematics difficulties (MD), hindering their overall mathematical development. To improve WPS proficiency, providing individualized and intensive interventions is critical. This umbrella review examined 11 medium- to high-quality meta-analyses to identify intervention and participant characteristics, informed by the Taxonomy of Intervention Intensity (TII) framework, that consistently moderate WPS outcomes for students with MD.

Impact of BMI on fertility in an otherwise healthy population: a systematic review and meta-analysis.

Background: An increased body mass index (BMI) can lead to subfertility; however, current literature fails to exclude the effect of other confounding medical conditions, raising questions regarding the direct link between increased BMI and fertility outcomes.

Objectives: To conduct a systematic review and meta-analysis to elucidate the effects of increased BMI on fertility outcomes in females with no other comorbidities.

Search Strategy: A comprehensive search was conducted using EMBASE, MEDLINE and the Cochrane library from January 2000 until July 2023.

Adeno-associated virus 9 (AAV9) viral proteins VP1, VP2, and membrane-associated accessory protein (MAAP) differentially influence transgene expression.

Unlabelled: Adeno-associated virus (AAV) is a with a ssDNA ~4.7 kb genome in a ~25 nm icosahedral capsid structure. AAV genomes encode nine known functional proteins from two open reading frames between two inverted terminal repeats (ITRs).

Accelerated Partial Breast Irradiation for Early-Stage Invasive Lobular Carcinoma.

Purpose: Invasive lobular carcinoma (ILC) represents 10% to 15% of invasive breast cancers with limited representation among trials of accelerated partial breast irradiation (APBI). Contemporary guidelines advise against treating ILC with APBI given a paucity of supportive evidence. Here, we evaluated oncologic outcomes among patients with ILC treated with APBI.

What are the Tools in Your CM Toolbox for Pain?

Some estimate that 1.5 billion people worldwide suffer from chronic pain. In the United States, chronic pain affects about 20% of the people with an annual cost of $600 billion.

Androgen receptor modulatory miR-1271-5p can promote hormone sensitive prostate cancer cell growth.

In most patients with advanced prostate cancer treated with hormonal therapy, androgen independence eventually emerges, leading to death. Androgen receptor signalling remains an important prostate cancer driver, even in the advanced disease stage. MicroRNAs (miRs), non-coding RNAs that regulate gene expression by inhibiting translation and/or promoting degradation of target mRNAs, can act as tumour suppressors or "oncomiRs" and modulate tumour growth.

Echocardiographic Functional Outcomes Following Regional Nodal Irradiation for Breast Cancer Using Volumetric Modulated Arc Therapy.

Purpose: Regional nodal irradiation (RNI) for breast cancer yields improvements in disease outcomes, yet comprehensive target coverage often increases cardiac radiation therapy (RT) dose. Volumetric modulated arc therapy (VMAT) may mitigate high-dose cardiac exposure, although it often increases the volume of low-dose exposure. The cardiac implications of this dosimetric configuration (in contrast to historic 3D conformal techniques) remain uncertain.

RAD52 resolves transcription-replication conflicts to mitigate R-loop induced genome instability.

Collisions of the transcription and replication machineries on the same DNA strand can pose a significant threat to genomic stability. These collisions occur in part due to the formation of RNA-DNA hybrids termed R-loops, in which a newly transcribed RNA molecule hybridizes with the DNA template strand. This study investigated the role of RAD52, a known DNA repair factor, in preventing collisions by directing R-loop formation and resolution.

Micronuclear collapse from oxidative damage.

Chromosome-containing micronuclei are a hallmark of aggressive cancers. Micronuclei frequently undergo irreversible collapse, exposing their enclosed chromatin to the cytosol. Micronuclear rupture catalyzes chromosomal rearrangements, epigenetic abnormalities, and inflammation, yet mechanisms safeguarding micronuclear integrity are poorly understood.

Molecular Analysis of Salivary and Lacrimal Adenoid Cystic Carcinoma.

Adenoid cystic carcinoma (ACC) of head and neck origin is associated with slow but relentless progression and systemic metastasis, resulting in poor long-term survival rates. ACC does not respond to conventional chemotherapy. Determination of molecular drivers may provide a rational basis for personalized therapy.
