Association of late eating with colorectal adenomas: a cross-sectional study.

Purpose: Colorectal cancer (CRC) is linked to lifestyle exposures. However, changes in the CRC rates among younger populations remain poorly understood and suggest the existence of yet unidentified factor(s) that may contribute to colon carcinogenesis. Here, we investigated the potential role of time of eating in the risk of pre-cancerous colonic neoplasms (tubular adenoma: TA).

PFAS Levels, Early Life Factors, and Mammographic Breast Density in Premenopausal Women.

Background: Mammographic breast density (MBD) is a strong risk factor and an intermediate phenotype for breast cancer, yet there are limited studies on how environmental pollutants are associated with MBD.

Objective: We investigated associations of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonate (PFHxS) levels with measures of MBD and evaluated if early life factors modified any associations.

Methods: Metabolon performed metabolomics analysis using ultrahigh-performance liquid chromatography/tandem accurate mass spectrometry in fasting blood from 705 premenopausal women completing their annual screening mammogram in St.

The Role of Residential Segregation in Treatment and Outcomes of Ductal Carcinoma In Situ of the Breast.

Background: It remains unclear whether residential segregation impacts on clinical treatment and outcomes for ductal carcinoma in situ (DCIS), a nonobligate precursor to invasive breast cancer (IBC).

Methods: This population-based retrospective cohort study included adult non-Hispanic White and Black women diagnosed with unilateral DCIS between January 1990 and December 2015, followed through December 2016, and identified from the Surveillance, Epidemiology, and End Results dataset. County-level racialized economic segregation was measured using the Index of Concentration at the Extremes.

A qualitative exploration of disseminating research findings among public health researchers in China.

Background: Research dissemination is essential to accelerate the translating of evidence into practice. Little is known about dissemination among Chinese public health researchers. This study aimed to explore the understanding and practices of disseminating research findings and to identify barriers and facilitators that influence dissemination activities to non-research audiences.

Phase 3 Trial of Cabozantinib to Treat Advanced Neuroendocrine Tumors.

Background: Treatment options for patients with advanced neuroendocrine tumors are limited. The efficacy of cabozantinib in the treatment of previously treated, progressive extrapancreatic or pancreatic neuroendocrine tumors is unclear.

Methods: We enrolled two independent cohorts of patients - those with extrapancreatic neuroendocrine tumors and those with pancreatic neuroendocrine tumors - who had received peptide receptor radionuclide therapy or targeted therapy or both.

M3NetFlow: A novel multi-scale multi-hop graph AI model for integrative multi-omic data analysis.

Multi-omic data-driven studies, characterizing complex disease signaling system from multiple levels, are at the forefront of precision medicine and healthcare. The integration and interpretation of multi-omic data are essential for identifying molecular targets and deciphering core signaling pathways of complex diseases. However, it remains an open problem due the large number of biomarkers and complex interactions among them.

Using National Public Health Accreditation to Explore Quality Improvement and Performance Management in Small Local Health Departments.

Objective: The objective of this study was to explore the experiences of 4 small LHDs related to Quality Improvement (QI) and Performance Management (PM) in their pursuit of PHAB reaccreditation or Pathways Recognition.

Design: A team of researchers conducted 22 qualitative interviews with health department leaders and staff.

Prophylactic antibiotics for excision of premalignant vulvar lesions: A pilot randomized controlled trial.

No prospective data have been described to inform guidelines on antibiotic prophylaxis for partial vulvectomies. Thus, we conducted a single-center, pilot, double-blind randomized controlled trial to assess the effectiveness of prophylactic antibiotics to prevent wound complications after partial vulvectomies. Patients were randomly assigned 1:1 to preoperative antibiotics or no preoperative antibiotics.

Tissue determinants of the human T cell receptor repertoire.

98% of T cells reside in tissues, yet nearly all human T cell analyses are performed from peripheral blood. We single-cell sequenced 5.7 million T cells from ten donors' autologous blood and tonsils and sought to answer key questions about T cell receptor biology previously unanswerable by smaller-scale experiments.

Epigenetic therapy potentiates transposable element transcription to create tumor-enriched antigens in glioblastoma cells.

Inhibiting epigenetic modulators can transcriptionally reactivate transposable elements (TEs). These TE transcripts often generate unique peptides that can serve as immunogenic antigens for immunotherapy. Here, we ask whether TEs activated by epigenetic therapy could appreciably increase the antigen repertoire in glioblastoma, an aggressive brain cancer with low mutation and neoantigen burden.

IL-10R inhibition reprograms tumor-associated macrophages and reverses drug resistance in multiple myeloma.

Multiple myeloma (MM) is the cancer of plasma cells within the bone marrow and remains incurable. Tumor-associated macrophages (TAMs) within the tumor microenvironment often display a pro-tumor phenotype and correlate with tumor proliferation, survival, and therapy resistance. IL-10 is a key immunosuppressive cytokine that leads to recruitment and development of TAMs.

Inflammation, physical activity, and disease-free survival in stage III colon cancer: Cancer and Leukemia Group B-Southwest Oncology Group 80702 (Alliance).

Background: Inflammation and insufficient physical inactivity contribute to individual-level risk of disease recurrence and death in stage III colon cancer. The extent to which increased inflammatory risk can be offset by sufficient physical activity remains unknown.

Methods: This cohort study was nested within the Cancer and Leukemia Group B (now part of the Alliance for Clinical Trials in Oncology) and Southwest Oncology Group randomized trial.

Quality of life and survivorship in patients with low-grade ovarian cancer.

Objective: High-grade (HGOC) and low-grade ovarian carcinoma (LGOC) are distinct malignancies with different biological features, treatment paradigms, and life expectancies. However, differences in quality of life (QOL), sleep, and depressive symptoms have not been examined by grade, and neither have inflammatory profiles associated with these symptoms. We aim to characterize QOL and biomarkers by OC grade.

Traversing the bench to bedside journey for iNKT cell therapies.

Invariant natural killer T (iNKT) cells are immune cells that harness properties of both the innate and adaptive immune system and exert multiple functions critical for the control of various diseases. Prevention of graft-versus-host disease (GVHD) by iNKT cells has been demonstrated in mouse models and in correlative human studies in which high iNKT cell content in the donor graft is associated with reduced GVHD in the setting of allogeneic hematopoietic stem cell transplants. This suggests that approaches to increase the number of iNKT cells in the setting of an allogeneic transplant may reduce GVHD.

Somatic mutation phasing and haplotype extension using linked-reads in multiple myeloma.

Somatic mutation phasing informs our understanding of cancer-related events, like driver mutations. We generated linked-read whole genome sequencing data for 23 samples across disease stages from 14 multiple myeloma (MM) patients and systematically assigned somatic mutations to haplotypes using linked-reads. Here, we report the reconstructed cancer haplotypes and phase blocks from several MM samples and show how phase block length can be extended by integrating samples from the same individual.

Untargeted lipidomics reveals racial differences in lipid species among women.

Understanding the biological mechanisms underlying racial differences in diseases is crucial to developing targeted prevention and treatment. There is, however, limited knowledge of the impact of race on lipids. To address this, we performed comprehensive lipidomics analyses to evaluate racial differences in lipid species among 506 non-Hispanic White (NHW) and 163 non-Hispanic Black (NHB) women.

Equipping the Public Health Workforce of the Future: Evaluation of an Evidence-Based Public Health Training Delivered Through Academic-Health Department Partnerships.

Objective: Maintaining a skilled public health workforce is essential but challenging given high turnover and that few staff hold a public health degree. Situating workforce development within existing structures leverages the strengths of different organizations and can build relationships to address public health challenges and health equity. We implemented and evaluated an innovative, sustainable model to deliver an established evidence-based public health (EBPH) training collaboratively among Prevention Research Centers (PRC), local and state health departments, and Public Health Training Centers (PHTC).

Sugar and sugar-sweetened beverages in relation to premature aging in adult survivors of childhood cancer.

Background: Premature aging is a significant concern in adult survivors of childhood cancer as they develop aging-related conditions at a younger age than their peers with no history of childhood cancer. Although modifiable lifestyle factors, such as diet, are postulated to affect aging process, supporting evidence is sparse.

Methods: We examined if the consumption of sugar and sugar-sweetened beverages was related to premature aging in 3322 adult survivors of childhood cancer in the St.

Hierarchical tricarboxylic acid cycle regulation by hepatocyte arginase 2 links the urea cycle to oxidative metabolism.

Urea cycle impairment and its relationship to obesity and inflammation remained elusive, partly due to the dramatic clinical presentation of classical urea cycle defects. We generated mice with hepatocyte-specific arginase 2 deletion (Arg2) and revealed a mild compensated urea cycle defect. Stable isotope tracing and respirometry revealed hepatocyte urea and TCA cycle flux defects, impaired mitochondrial oxidative metabolism, and glutamine anaplerosis despite normal energy and glucose homeostasis during early adulthood.
