Repeated cuff inflation may cause discomfort and reduce acceptance of out-of-office BP monitoring. To address this, we developed a novel low-pressure and rapid oscillometric method designed to reduce maximum cuff pressure (MaxCP) and measurement duration. In this participant-blinded crossover study, we evaluated cuff-related measurement burden using the Omron HEM-7290T, the first automated upper-arm BP monitor to use the novel method. The HEM-7290T was compared with an otherwise identical device using a conventional inflation-based method (Reference A; n = 110 participants) and with a conventional deflation-based oscillometric BP monitor (Reference B; n = 93 participants). The primary endpoint was the difference in visual analog scale (VAS) score for perceived cuff tightness. Compared with Reference A and Reference B, HEM-7290T reduced VAS scores by 8.6 points (95% CI, 6.5-10.8; p < 0.001) and 9.5 points (95% CI, 7.1-11.8; p < 0.001), respectively. Greater reductions in VAS scores were associated with more frequent selection of the HEM-7290T measurement as the one associated with the least perceived cuff tightness. Compared with Reference A and Reference B, respectively, MaxCP was reduced by 32.0 mmHg and 51.0 mmHg, while measurement duration was reduced by 6.8 s and 14.5 s.

We evaluated BP control and associated factors using the Japan Medical Association Database of Clinical Medicine (J-DOME), a nationwide primary care registry. This cross-sectional study included patients with hypertension registered in 2024, categorized by treatment by specialists certified by the Japanese Society of Hypertension. Multivariable logistic regression identified factors associated with achieving office BP < 130/80 mmHg. Among 2663 patients (43.6% women; mean age, 71.4 years), 545 were treated by hypertension specialists. Mean BP was 134.4/74.8 mmHg, and the mean number of antihypertensive drugs was 1.6. Systolic BP was similar between specialist- and non-specialist-treated patients (135.1 vs. 134.2 mmHg; p = 0.28), whereas diastolic BP (76.1 vs. 74.5 mmHg; p = 0.0060) and the number of drugs (1.9 vs. 1.6; p < 0.0001) were higher in the specialist-treated group.

Here, we investigated the renal and skeletal consequences of high salt loading and the protective effects of esaxerenone, a selective nonsteroidal mineralocorticoid receptor (MR) antagonist. Male Sprague-Dawley rats were infused with aldosterone and fed an 8% sodium chloride diet for 4 weeks (Aldo-HS), with or without esaxerenone. Trabecular bone architecture was assessed by micro-computed tomography, three-dimensional morphometry, and histomorphometry. Kidney and bone transcriptomes were analyzed using RNA sequencing and weighted gene co-expression network analysis. Aldo-HS rats developed marked renal calcium wasting without changes in serum calcium, phosphate, parathyroid hormone, or fibroblast growth factor 23 levels. Fractional calcium excretion was strongly inversely correlated with trabecular bone volume (r = -0.74, p < 0.001). Aldosterone-salt loading induced substantial trabecular bone loss, which was prevented by esaxerenone. Bone transcriptomic analysis demonstrated suppression of extracellular matrix gene programs; a collagen-enriched gene module (including Col1a1, Col1a2, Col11a1) was tightly linked to calcium wasting (r = -0.97, p < 0.001), partially restored by MR blockade, and overlapped with loci associated with bone mineral density in human genome-wide association studies. Aldosterone-salt loading induces trabecular bone loss accompanied by imbalance in bone remodeling and renal calcium wasting. MR blockade preserves skeletal integrity, supporting a modifiable bone-kidney axis and providing translational insight into skeletal complications of mineralocorticoid excess.</p>","PeriodicalId":13029,"journal":{"name":"Hypertension Research","volume":" ","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149108720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SD of home systolic BP followed a similar seasonal pattern (standardized differences: 0.07-0.18). Although winter-summer differences in VIM were also significant in several strata, particularly among males, their magnitudes were small (standardized differences ≤0.09).

Conventional telemonitoring has primarily relied on remote transmission of BP measurements to support clinician-directed treatment adjustment. However, recent advances in digital health technologies and the emergence of digital hypertension have substantially broadened the role of telemonitoring in hypertension care. Within the framework of digital hypertension, telemonitoring is evolving beyond simple BP surveillance in three major domains. First, advances in data monitoring enable the integration of multidimensional health information, including physical activity, sleep patterns, medication adherence, and environmental exposures, with longitudinal BP measurements. Second, physician-support technologies, such as automated data integration, clinical decision-support systems, and artificial intelligence-based analytics, facilitate the interpretation of large-scale patient-generated data and support timely clinical intervention. Third, patient-support technologies, including digital therapeutics, provide continuous behavioral interventions and self-management support between clinic visits. Despite these advances, several challenges remain, including ensuring data quality and standardization, integration into clinical workflows, long-term patient engagement, digital inequalities, and concerns regarding privacy and data governance. Future research should focus on optimizing the clinical use of multidimensional health data, evaluating the effects of advanced telemonitoring strategies on long-term clinical outcomes, and establishing effective implementation models for routine practice.
