Using the Socioecological Model to Understand Medical Staff and Older Adult Patients' Experience with Chronic Pain: A Qualitative Study in an Underserved Community Setting.

Purpose: Chronic pain is highly prevalent and disabling for older adults, particularly those from underserved communities. However, there is an absence of research on how contextual (eg, community/societal) factors interact with pain for these patients. Informed by the socio-ecological model, this study aimed to elucidate the individual, interpersonal, community, and societal factors associated with chronic pain from the perceptions of older adult patients and medical staff in a community clinic.

"Pushed to Their Limits": Health Care Provider Perspectives on Barriers and Facilitators to Implementing a Mind-Body and Activity Program for Older Adults With Chronic Pain in a Community Clinic for the Underserved.

Older adults from underserved backgrounds experience chronic pain at a rate of 60% to 75%. Pharmacological treatments have limited efficacy and involve considerable risks. Mind-body interventions hold promise to improve pain outcomes but are typically not implemented in community clinics in which they are needed most, thus contributing to health disparities in chronic pain treatment.

Improving Health for Older Adults With Pain Through Engagement: Protocol for Tailoring and Open Pilot Testing of a Mind-Body Activity Program Delivered Within Shared Medical Visits in an Underserved Community Clinic.

Background: Chronic musculoskeletal pain is prevalent and disabling among older adults in underserved communities. Psychosocial pain management is more effective than pharmacological treatment in older adults. However, underserved community clinics often lack psychosocial treatments, in part because of a lack of trained providers.

Sparse Deconvolution and Causality Analysis of Inflammatory Markers During Cardiac Surgery.

Major bodily trauma such as cardiac surgery elicits (in response to tissue injury and other exogenous surgical factors) a whole-body inflammation response during which specialized signaling proteins called cytokines are synthesized and invoke multiple defense mechanisms. Many proinflammatory and anti-inflammatory cytokines such as interleukins (IL) and tumor necrosis factor (TNF) are produced to initiate bodily repair. Due to the adverse health consequences, including mortality, of a maladaptive cytokine response, understanding their complex dynamics using system-theoretic modeling and analysis may pave the way for controlling the inflammatory response which may eventually improve medical outcomes for patients.

Characterizing Alterations in Cortisol Secretion During Cardiac Surgery.

Cortisol is a neuroendocrine hormone of the hypothalamus-pituitary-adrenal (HPA) axis secreted from adrenal glands in response to stimulation by adrenocorticotropic hormone (ACTH) from the anterior pituitary and corticotropin releasing hormone (CRH) from the hypothalamus. Cortisol has multiple functionalities in maintaining bodily homeostasis - including anti-inflammatory influences - through its diurnal secretion pattern (which has been studied extensively); its secretion is also increased in response to major traumatic events such as surgery. Due to the adverse health consequences of an abnormal immune response, it is crucial to understand the effect of cortisol in modulating inflammation.

Optimal transport and control of active drops.

Understanding the complex patterns in space-time exhibited by active systems has been the subject of much interest in recent times. Complementing this forward problem is the inverse problem of controlling active matter. Here, we use optimal control theory to pose the problem of transporting a slender drop of an active fluid and determine the dynamical profile of the active stresses to move it with minimal viscous dissipation.
