Pain is common among adults with heart failure (HF), but pain subtypes and associated biomarkers are understudied. The aims were to: 1) characterize chronic pain severity, neuropathic pain quality, locations, and subtypes; and 2) compare pain severity and levels of biomarkers among pain subtypes. An exploratory aim was to correlate levels of biomarkers with pain severity. This pilot descriptive study included cross-sectional data from 60 adults with HF and chronic pain. Pain was evaluated using the PainDETECT questionnaire. Blood biomarkers included interleukin (IL)-10, IL-18, IL-1β, IL-33, IL-6, IL-8, tumor necrosis factor (TNF)-α, brain-derived neurotrophic factor, leptin, adiponectin, and C-reactive protein. Descriptive statistics, Chi-square test of homogeneity, one-way analysis of variance, and Spearman correlation were used for analyses. The mean age was 70.45 (SD 7.92) years. The sample consisted of 63.3% women and 65.0% White race. Participants primarily reported nociceptive pain only (73.3%) with fewer reporting neuropathic pain only (6.7%) and mixed pain (20.0%). Current and 4-week mean pain severity scores were highest in the mixed pain subtype (p both <.05). No biomarkers were significantly different across the pain subtypes, but lower lL-10 (p=.049), and IL-33 (p=.014), were associated with higher pain severity. In this study, chronic pain and its association with underlying biomarkers were characterized. Future research with a larger sample is needed to understand the unique contributions of biomarkers with targeted pain phenotypes. Show less

Hypertension is a global target for noncommunicable diseases, and meditation-based interventions (MBIs) benefit patients with hypertension (HTN). The primary objective of this scoping review is to map the globally published MBI studies on patients with HTN. The secondary goal is to identify the role of brain-derived neurotrophic factor (BDNF) in HTN. Based on the Arksey and O'Malley protocol of the Joanna Briggs Institute framework for scoping review, 5 electronic databases were searched with search terms related to HTN and meditation. The open-access articles in the English language published between 1985 and 2024 were selected. The selected articles involved MBIs. All the studies were uploaded to the Rayyan software. Two reviewers worked independently and in duplicate to screen the studies first for title and abstract, and then for full text. Data were extracted based on the template for the intervention description and replication checklist. The data were summarized and reported as a narrative summary. In total, 966 studies were identified. After removing 429 duplicates, 537 studies were screened for their titles and abstracts. 467 studies were excluded based on the inclusion and exclusion criteria, 18 were not retrieved, and 20 were excluded with reasons. Finally, the full texts of 70 studies were read. 32 eligible studies were included in this review. The studies were divided into 3 categories based on meditation and into 7 categories based on outcome. Moreover, no study involving human subjects has analyzed the level of BDNF in HTN patients receiving MBIs. MBIs have shown promising results among HTN patients. There is a research gap in studies related to BDNF and meditation among hypertensive patients. The limitation of the review is the inclusion of open-access articles published only in the English language. Hypertension, Meditation, Mindfulness, Brain-Derived Neurotrophic Factor. Show less
