Objectives: The purpose of this study was to systematically analyze the studies of hypertension associated with obstructive sleep apnea to assess the current status and hot spots in this field.
Methods: We searched the Web of Science Core Collection for publications related to hypertension associated with obstructive sleep apnea published before July 3, 2021. Bibliometric analyses and science mappings were carried out using the CiteSpace 5.8.R1 and Microsoft Office Excel 2019. CiteSpace 5.8.R1 was used to visualize the distribution of research fields, analyze co-occurring keywords and burst terms to detect trends and frontiers, and identify leading collaborations among countries, authors, and institutions. Microsoft Office Excel 2019 was used to make bar graphs, histograms and line graphs.
Results: According to the search strategy, a total of 7263 published articles and reviews were retrieved. The research on hypertension associated with obstructive sleep apnea has been developing quickly at present. Sleep and Breathing was the most productive journal. The USA was a major producing country and Harvard Medical School was the most productive institution in this field. In the field of hypertension associated with obstructive sleep apnea, the main research hotspots were continuous positive airway pressure, cardiovascular disease, and obesity.
Conclusions: The present study provides a new perspective for the study of hypertension associated with obstructive sleep apnea and valuable information for researchers to find potential partners and cooperative institutions, hot issues and research frontiers.

Background: Age-related macular degeneration (AMD) decrease vision and presents considerable challenges for both public health and clinical management strategies. Obesity is usually implicated with increased AMD, and body mass index (BMI) does not reflect body fat distribution. An array of studies has indicated a robust relationship between body fat distribution and obesity.

Background: Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder affecting multiple systems. However, arterial stenosis is a rare manifestation in patients with NF1. Since the symptoms of arterial stenosis caused by NF1 are often atypical and have a high under-diagnosis rate, this can lead to serious complications such as hypertension, ischemic stroke, or even death.

Background: The health benefits of physical activity, including walking, are well-established, but the relationship between daily step count and mortality in hypertensive populations remains underexplored. This study investigates the association between daily step count and both all-cause and cardiovascular mortality in hypertensive American adults.
Methods: We used data from the National Health and Nutrition Examination Survey 2005-2006, including 1,629 hypertensive participants with accelerometer-measured step counts.
Red cell distribution width as a cardiovascular risk predictor in adults with hypertension in sub-Saharan Africa.

Article Synopsis
- Red cell distribution width (RDW) is a measure of variability in red blood cell sizes and may indicate cardiovascular disease (CVD) risk, especially in low-resource areas, according to a study in Ghana and Nigeria.
- The study involved 319 adults with hypertension who underwent assessments like blood pressure and RDW measurement, revealing an average RDW of 13.96% and a median CVD risk score of 8.11%.
- Findings showed that RDW is positively correlated with age, systolic and diastolic blood pressure, and WHO CVD risk scores, suggesting RDW could be a useful predictor of CVD risk in this population, particularly with an RDW cutoff of >14
