A Brief History Of Antenatal Colostrum Expression, And Where To From Here, Therese A. O’Sullivan, Connie N. Ihlein

Research outputs 2022 to 2026

The practice of antenatal colostrum expression (ACE), or the extraction of colostrum from the breasts during pregnancy, has an interesting history and continues to evolve. This narrative review aims to describe how perception and practices of ACE have changed over time, summarise the evidence on ACE in maternal and infant care, and highlight areas for future research. The literature demonstrates that ACE is safe for low-risk women when done from around 36 weeks’ gestation. Women should be reassured that the skill of hand expressing is a valuable tool post-birth, regardless of whether they are able to collect colostrum antenatally or …

Exercise Science Faculty Research and Publications

Introduction

United States (U.S.) military veterans experience significant physical health problems. Lifestyle modifications, such as increasing daily physical activity, are often considered the first course of action in treatment for the general public. However, veterans report low levels of physical activity, often due to perceived barriers to engaging in exercise. Trauma exposure type and cumulative trauma burden may be differentially associated with exercise attitudes and behaviors.

Methods

We surveyed U.S. military veterans on perceived self-efficacy to overcome barriers to engaging in exercise and physical activity levels. Additionally, we explored the relationship between the type of traumatic event exposure and cumulative …

Background: Delayed excretion of high-dose methotrexate (HD-MTX) in pediatric acute lymphoblastic leukemia (ALL) can result in significant morbidity. While methotrexate is primarily renally excreted, HD-MTX may overwhelm renal excretion and increase reliance on fecal elimination. This study evaluated the association between laxative use for constipation and delayed excretion of HD-MTX.

Methods: This multisite chart review included pediatric patients with ALL (2010-2020) who received HD-MTX (5 g/m2). Delayed excretion was defined as a serum MTX concentration greater than 0.4 µM at Hour 48. We identified use of laxative medications after each HD-MTX infusion, with receipt of two or more doses considered …

Folate Receptor Β Performs An Immune Checkpoint Function In Activated Macrophages, Fenghua Zhang, Md Yusuf Al-Amin, Sagar Utturkar, Rina Jiang, Gregory Cresswell, Rami Alfar, Ian Ophaug-Johansen, Gabriel Bachman, Madduri Srinivasarao, Richard Finnell, Amaya Puig-Kröger, Timothy Ratliff, Philip S Low

Faculty, Staff and Students Publications

Monocytes and macrophages are sentinels of the immune system that distinguish themselves from other cells by expressing the beta isoform of the folate receptor (FRβ). Because FRβ does not bind folate until the monocyte/macrophage is exposed to immunosuppressive cytokines, the question naturally arose whether FRβ might also perform an immune-related function. To examine this matter, we compared the properties of wild type (WT) and FRβ knockout mice. We observe that FRβ knockout (KO) mice display autoimmune symptoms that can include alopecia, enlarged spleens, and dermatitis, despite having normal cellular folate levels. We further demonstrate that syngeneic tumors (TRAMP C2, MC38) …
