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

Symptomatic neuromas result from disorganized nerve growth at the site of amputation, causing pain that affects recovery and quality of life. In patients with diabetes mellitus (DM), nerve regeneration is impaired, compounded by comorbidities such as obesity, hypertension, and hyperlipidemia. Surgical approaches including targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) have shown promise for managing symptomatic neuroma, but their effectiveness in diabetic patients is uncertain due to unique challenges in nerve regeneration. This narrative review explores the protective effects of DM on symptomatic neuroma formation and to evaluate the implications for surgical intervention. A systematic search of PubMed was conducted, and relevant studies discussing symptomatic neuroma formation in amputees were included. Symptomatic neuromas were reported in 9.5-50% of amputees involving 9.5% of upper extremity, and 3.8% of lower extremity amputees. Younger age and proximal amputations were identified as significant risk factors. While it is suggested that Interleukin (IL)-10 and brain-derived neurotropic factor (BDNF) levels are involved in protecting against symptomatic neuroma formation, IL-1β and IL-6 promote neuroma formation. Although evidence is mixed, some evidence suggests that DM and diabetic peripheral neuropathy decrease symptomatic neuroma formation by impairing axonal regeneration, altering the extracellular matrix and modulating inflammatory responses. Although surgical approaches such as TMR and RPNI have shown potential in reducing neuroma-related pain, further studies are needed to ensure that this benefit extends to diabetic patients whose disease puts them at increased risk of postoperative complications. Additional studies are required to confirm these findings and optimize surgical strategies for high-risk patient populations. Show less
