Rationale: Unrecognised coronary artery disease (CAD) may contribute to adverse outcomes in chronic obstructive pulmonary disease (COPD). Improved identification of at-risk groups could inform better preventative care. We aimed to evaluate the burden and relationships of radiologically detectable CAD in COPD, establish frequency of occult disease, and examine potential cardiovascular screening methods.

Article Synopsis
  • - Respiratory viruses, especially rhinoviruses, contribute to exacerbations of chronic obstructive pulmonary disease (COPD), with some patients experiencing frequent flare-ups (≥2 per year).
  • - A study found that COPD patients had significantly reduced responses of interferons (IFNs) in their alveolar macrophages, particularly those with frequent exacerbations compared to infrequent ones and healthy individuals.
  • - Pro-inflammatory cytokines were elevated in uninfected bronchial epithelial cells (BECs) from COPD patients; however, the response to viral infection did not differ between COPD patients and healthy subjects.

Enteric neurons control gut physiology by regulating peristalsis, nutrient absorption, and secretion . Disruptions in microbial communities caused by antibiotics or enteric infections result in the loss of enteric neurons and long-term motility disorders . However, the signals and underlying mechanisms of this microbiota-neuron communication are unknown.

Importance: Multicomponent electronic patient-reported outcome cancer symptom management systems reduce symptom burden. Whether all components contribute to symptom reduction is unknown.

Objective: To deconstruct intervention components of the Symptom Care at Home (SCH) system, a digital symptom monitoring and management intervention that has demonstrated efficacy, to determine which component or combination of components results in the lowest symptom burden.

Introduction: Medications for opioid use disorder (MOUD) are the most effective interventions for this condition, yet many patients discontinue treatment. Though adjunct psychosocial treatments are recommended to increase retention and reduce relapse, the scarcity of trained providers hinders access to and utilization of evidence-based interventions. We conducted a Phase 1 study to assess the feasibility of a virtual reality-delivered Mindfulness-Oriented Recovery Enhancement (MORE-VR) intervention for patients receiving MOUD.
