DNA methylation is an important epigenetic mechanism that helps define and maintain cellular functions. It is influenced by many factors, including environmental exposures, genotype, cell type, sex, and aging. Since age is the primary risk factor for developing neurodegenerative diseases, it is important to determine if aging-related DNA methylation is retained when cells are reprogrammed to an induced Pluripotent Stem Cell (iPSC) state.

Despite a well-established system of community lands, the current lack of spatial data on community territories impacts how Indigenous peoples and local communities (IPs and LCs) in Europe are included in global discussions about land rights recognition and their critical role in land stewardship. We present an aggregation of spatial data for 41 Mha of recognized IPs and LCs lands in Western and Northern Europe, including data that were not previously included in global datasets. We show that governments recognize IPs and LCs lands through a diversity of tenure systems, which are managed under a variety of governance arrangements, including community, State, and shared governance.

Healthcare debriefing is a cognitively demanding conversation after a simulation or clinical experience that promotes reflection, underpinned by psychological safety and attention to learner needs. The process of debriefing requires mental processing that engages both "fast" or unconscious thinking and "slow" intentional thinking to be able to navigate the conversation. "Fast" thinking has the potential to surface cognitive biases that impact reflection and may negatively influence debriefer behaviors, debriefing strategies, and debriefing foundations.

Waldenstrom macroglobulinemia (WM) is a non-Hodgkin B-cell lymphoma, characterized by bone marrow infiltration with plasma cells and lymphocytes. The tumor microenvironment (TME) plays an important role in mediating WM cell biology, but the effects of macrophages on WM biology remains unclear. Here, we investigated the effects of macrophages on WM growth and survival and identified a novel role for transcription factor GLI3 in macrophage polarization.

Lower obstetrician and gynecologist (OBGYN) supply in abortion-ban states, despite minimal state-level changes in the 2 years post-.

Health Aff Sch

December 2024

Fitzhugh Mullan Institute for Health Workforce Equity, Department of Health Policy and Management, Milken Institute School of Public Health, George Washington University, Washington, DC 20037, United States.

Since the Supreme Court decision in June 2022, emerging reports suggest that the obstetrician and gynecologist (OBGYN) workforce is moving into states without abortion bans. Using a large national administrative database, we identified OBGYNs enrolling in new states from July 2017 through June 2024. We used difference-in-differences (DID) analyses to estimate the effect of on enrollments by state abortion policy (ban vs no ban).

Article Synopsis
  • Current epilepsy treatment often relies on trial-and-error with anti-seizure medications (ASMs), which can delay finding the best treatment for patients.
  • Machine learning (ML) is emerging as a helpful tool to predict how well patients will respond to ASMs based on various data inputs like clinical history and genetic information.
  • Although 37 studies show mixed results with some ML models performing excellently, more research is needed to enhance these models and make them practical for use in clinical settings.

TFAP2C-DDR1 axis regulates resistance to CDK4/6 inhibitor in breast cancer.

Cancer Lett

February 2025

Department of Biochemistry and Molecular Medicine, GWU Cancer Center, George Washington University School of Medicine and Health Sciences, Washington, DC, 20037, USA. Electronic address:

Breast cancer is the predominant malignancy with the majority of cases are characterized as HR+/HER2-subtype. Although cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) have shown remarkable efficacy in treating this subtype when combined with endocrine therapy, the development of resistance to these inhibitors remains a significant clinical obstacle. Hence, there is an urgent need to explore innovative therapies and decipher the underlying mechanisms of resistance to CDK4/6i.

Histone deacetylase 6 (HDAC6) inhibition is associated with an increased pro-inflammatory tumor microenvironment and antitumoral immune responses. Here, we show that the HDAC6 inhibitor AVS100 (SS208) had an antitumoral effect in SM1 melanoma and CT26 colon cancer models and increased the efficacy of anti-programmed cell death protein 1 treatment, leading to complete remission in melanoma and increased response in colon cancer. AVS100 treatment increased pro-inflammatory tumor-infiltrating macrophages and CD8 effector T cells with an inflammatory and T cell effector gene signature.

Section of General Internal Medicine, Boston University Chobanian and Avedisian School of Medicine, 801 Massachusetts Avenue, Room 2082, Boston, MA 02118, USA; GenderCare Center, Boston Medical Center, 801 Massachusetts Ave. Rm. 2082, Boston, MA, 02118 USA. Electronic address:

Transgender and gender diverse patients undergoing cardiac procedures require unique considerations to ensure the delivery of respectful, safe, and high-value health care. There are several issues for which practicing clinicians may have limited experience managing, including the potential interactions between gender-affirming medical and surgical interventions and cardiovascular conditions; using correct patient name and pronouns and additional strategies to increase comfort and safety of medical interventions; and nuances of cardiac clearance before gender-affirming surgeries. This article provides a primer on these topics and sets cardiologists up to learn more about the needs of transgender and gender diverse patient populations.
