ArXiv

January 2025

Center for Technology and Behavioral Health, Geisel School of Medicine, Dartmouth College, Lebanon, NH, United States.

Pretrained foundation models and transformer architectures have driven the success of large language models (LLMs) and other modern AI breakthroughs. However, similar advancements in health data modeling remain limited due to the need for innovative adaptations. Wearable movement data offers a valuable avenue for exploration, as it's a core feature in nearly all commercial smartwatches, well established in clinical and mental health research, and the sequential nature of the data shares similarities to language.

Anhedonia in flux: Understanding the associations of emotion regulation and anxiety with anhedonia dynamics in a sample with major depressive disorder.

J Affect Disord

March 2025

Center for Technology and Behavioral Health, Geisel School of Medicine, Dartmouth College, Lebanon, NH, United States; Department of Biomedical Data Science, Geisel School of Medicine, Dartmouth College, Lebanon, NH, United States; Department of Psychiatry, Geisel School of Medicine, Dartmouth College, Hanover, NH, United States; Department of Computer Science, Dartmouth College, Hanover, NH, United States.

Negative rumination and emotion regulation difficulties have been consistently linked with depression. Despite anhedonia-the lack of interest in pleasurable experiences-being a cardinal symptom of depression, emotion regulation of positive emotions, including dampening, are considered far less in the literature. Given that anhedonia may manifest through blunted responses to previously positive or enjoyable experiences, it is vital to understand how different positive emotion regulation strategies impact anhedonia symptom severity and how it can vary or change over time.

Background: As the opioid epidemic continues to have a major negative impact across the US, community pharmacies have come under scrutiny from legal systems attempting to hold them accountable for their role in over dispensing and lack of patient intervention. While the most available tool for monitoring patients' opioid use is Prescription Drug Monitoring Programs (PDMP), these do not provide pharmacists with actionable information and decision support. Our study addresses this gap through three objectives: [1] incorporate validated opioid risk metric thresholds into a PDMP platform to create the Opioid Risk Reduction Clinical Decision Support (ORRCDS) tool; [2] assess ORRCDS' ability to reduce patient opioid risk; [3] assess ORRCDS' sustainability and viability for broader dissemination in community pharmacy.

Article Synopsis
  • Memories are formed in the brain during learning and become stable through a process called reactivation after the learning phase.
  • A strong negative experience in mice leads to the reactivation not just of that recent memory, but also of a related neutral memory formed two days earlier, linking these memories in a way that influences future fear responses.
  • The study suggests that this co-reactivation happens more during wakefulness and helps the brain integrate and relate different memories over time.

Psychological trauma has profound effects on brain function and precipitates psychiatric disorders in vulnerable individuals, however, the molecular mechanisms linking trauma with psychiatric risk remain incompletely understood. Using RNA-seq data postmortem brain tissue of a cohort of 304 donors (N=136 with trauma exposure), we investigated transcriptional signatures of trauma exposures in two cortical regions (dorsolateral prefrontal cortex, and dorsal anterior cingulate cortex) and two amygdala regions (medial amygdala and basolateral amygdala) associated with stress processing and regulation. We focused on dissecting heterogeneity of traumatic experiences in these transcriptional signatures by investigating exposure to several trauma types (childhood, adulthood, complex, single acute, combat, and interpersonal traumas) and interactions with sex.

  • Moral injury is being studied as a significant factor affecting the mental health and job satisfaction of healthcare workers (HCWs) due to stressful experiences they encounter.
  • A longitudinal study with 473 HCWs showed that witnessing or participating in potentially morally injurious events (PMIEs) increased burnout and turnover intentions, particularly among those who witnessed these events.
  • The findings suggest that organizations should address moral injury in HCWs by implementing strategies that consider the types of morally injurious experiences they face in their work.

Prior research has rarely examined how people understand or react to the names of psychological treatments. In the case of evidence-based psychotherapies for posttraumatic stress disorder (PTSD), such reactions may be relevant to the low rates of uptake of such treatments. Participants who screened positive for PTSD (n = 887) completed questions assessing their initial reactions to PTSD treatment names as well as how a different name would affect their openness to treatment.

Article Synopsis
  • Pain management is complicated, but recent fMRI studies link brain activity patterns to pain experiences, prompting exploration of whether manipulating these patterns can change pain perception.
  • Researchers developed a neurofeedback method using real-time fMRI data to help participants learn to control their pain-related brain activity, specifically the SIIPS (stimulus intensity independent pain signature).
  • The findings suggest that participants were able to successfully downregulate their pain responses during training, which correlated with reduced pain intensity after the intervention, highlighting the potential of neurofeedback in both clinical and research settings for pain management.

J Nutr

December 2024

Institute for Active Health, Kyoto University of Advanced Science, Kyoto, Japan; National Institute of Health and Nutrition, National Institutes of Biomedical Innovation, Health and Nutrition, Tokyo, Japan.

Article Synopsis
  • Doubly labeled water is the most reliable method for measuring total energy expenditure (TEE), but its accuracy can be affected by the isotope dilution space ratio (DSR).
  • This study explored factors like age, sex, ethnicity, body composition, and geographical elevation to see how they influence DSR, using various statistical analysis methods.
  • Results showed that while DSR decreased with age in individuals 60 and older, no significant effects were found from other variables, suggesting that previous estimates of TEE might be overestimating values for older individuals, especially those around 90 years old.
