A Pilot Randomized Controlled Trial to Examine the Impact of a Therapy Dog Intervention on Loneliness in Hospitalized Older Adults.

Innov Aging

September 2024

Department of Clinical Sciences, Center for Animals and Public Policy, Cummings School of Veterinary Medicine, Tufts University, North Grafton, Massachusetts, USA.

Background And Objectives: Loneliness is linked to significant health threats and is potentially more dangerous than obesity; it affects as many as 29% of noninstitutionalized older adults. Loneliness is exacerbated for those who require inpatient rehabilitation, are displaced from their social networks, spend little time receiving therapy, and are physically inactive and socially isolated. Emerging evidence suggests that companion animals provide a number of health and well-being benefits and that interacting with a trained therapy dog may reduce loneliness.

As researchers increasingly utilize systems science simulation modeling (SSSM), little is known about how and by whom SSSMs are being leveraged to address inequities in access to healthy diets. We evaluated the extent to which studies (n = 66) employing SSSM to examine retail food environments (RFEs): included three pillars of equity (social position, human capital, socioeconomic and political context) that shape RFEs and access to healthy diets; grounded model design and development in theory; engaged with diverse stakeholders and lived experiences related to RFEs; and translated model findings towards addressing inequities in RFEs. Most studies (n = 58) included some model characteristics related to social position (e.

Commutability is where the measurement response for a reference material (RM) is the same as for an individual patient sample with the same concentration of analyte measured using two or more measurement systems. Assessment of commutability is essential when the RM is used in a calibration hierarchy or to ensure that clinical measurements are comparable across different measurement procedures and at different times. The commutability of three new Standard Reference Materials (SRMs) for determining serum total 25-hydroxyvitamin D [25(OH)D], defined as the sum of 25-hydroxyvitamin D [25(OH)D] and 25-hydroxyvitamin D [25(OH)D], was assessed through an interlaboratory study.

Transcription factor networks in cellular quiescence.

Nat Cell Biol

January 2025

Department of Molecular, Cell and Developmental Biology, University of California, Los Angeles, Los Angeles, CA, USA.

Many of the cells in mammalian tissues are in a reversible quiescent state; they are not dividing, but retain the ability to proliferate in response to extracellular signals. Quiescence relies on the activities of transcription factors (TFs) that orchestrate the repression of genes that promote proliferation and establish a quiescence-specific gene expression program. Here we discuss how the coordinated activities of TFs in different quiescent stem cells and differentiated cells maintain reversible cell cycle arrest and establish cell-protective signalling pathways.

UW supplementation with AP39 improves liver viability following static cold storage.

Sci Rep

January 2025

Center for Engineering in Medicine and Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.

Static cold storage of donor livers at 4 °C incompletely arrests metabolism, ultimately leading to decreases in ATP levels, oxidative stress, cell death, and organ failure. Hydrogen Sulfide (HS) is an endogenously produced gas, previously demonstrated to reduce oxidative stress, reduce ATP depletion, and protect from ischemia and reperfusion injury. HS is difficult to administer due to its rapid release curve, resulting in cellular death at high concentrations.

Divergent roles of mA in orchestrating brown and white adipocyte transcriptomes and systemic metabolism.

Nat Commun

January 2025

Section of Islet Cell and Regenerative Biology, Joslin Diabetes Center; Department of Medicine, BIDMC; Harvard Stem Cell Institute, Harvard Medical School, Boston, MA, USA.

N-methyladenosine (mA) is among the most abundant mRNA modifications, yet its cell-type-specific regulatory roles remain unclear. Here we show that mA methyltransferase-like 14 (METTL14) differentially regulates transcriptome in brown versus white adipose tissue (BAT and WAT), leading to divergent metabolic outcomes. In humans and mice with insulin resistance, METTL14 expression differs significantly from BAT and WAT in the context of its correlation with insulin sensitivity.
