However, to date, no effective treatment has been established other than iatrogenic delivery, and the importance of prevention as an alternative approach to addressing PE has been emphasized. There is growing evidence on the effectiveness of pharmacological and non-pharmacological prophylaxis in preventing PE. In this review, we focused on dietary supplements as non-pharmacological prophylaxis for PE. Calcium is a well-documented supplement for the prevention of PE. Daily 500 mg calcium supplementation can roughly halve the risk of PE in settings where calcium intake is low, including in Japan. According to recent systematic reviews and network meta-analyses, current evidence on the efficacy of vitamin D supplementation is inconsistent. Although vitamin D is a candidate for the prevention of PE, future large-scale randomized control trials are necessary to draw definitive conclusions. We also reviewed other dietary supplements, including vitamins (vitamins A, B6, C, and E, folic acid, and multivitamins), minerals (magnesium, zinc, and iron), amino acids (l-arginine and l-carnitine), anti-oxidants (lycopene, resveratrol, and astaxanthin), and other agents (omega-3 fatty acids, coenzyme Q10, melatonin, and s-equol). In this study, we provide a comprehensive approach to help develop better preventive strategies and ultimately reduce the burden of PE.</p>","PeriodicalId":13029,"journal":{"name":"Hypertension Research","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390820","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}

We injected cholera toxin subunit B combined with Alexa Fluor™ 555, a nerve tracer, into the identified ARG and confirmed its innervation of the renal artery and kidney by observing fluorescence in adjacent tissues. Twelve experimental canines were divided equally into an intervention group, which received ARG ablation using 95% ethanol, and a sham control group, which received normal saline. Our results demonstrated that ARG ablation significantly reduced systolic, diastolic, and mean arterial pressures, with minimal impact on heart rate. Additionally, ARG ablation lowered plasma and renal cortex norepinephrine levels, and reduced tyrosine hydroxylase expression in the renal cortex. No adverse events were observed during the 3-month follow-up period. These findings suggest that the ARG may serve as a novel target for RDN and could offer a therapeutic alternative for patients who do not respond to or experience elevated BP after RDN.</p>","PeriodicalId":13029,"journal":{"name":"Hypertension Research","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390817","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}

However, few studies have focused on the details of previous cases of preeclampsia. This single-institution, retrospective study evaluated the risk of developing preeclampsia in subsequent pregnancies in patients with a history of preeclampsia. Among singleton pregnant women who delivered at our hospital between 2017 and 2021, those who developed hypertensive disorders of pregnancy (HDP) for the first time were recruited. We retrospectively followed patients who had a subsequent pregnancy and delivery at our hospital before 2023 for a recurrence of preeclampsia. Maternal characteristics, time of HDP onset, and mean arterial pressure (MAP) during the first and early second trimester of the subsequent pregnancy were recorded. Of the 7485 deliveries, 413 were first-episode HDP cases, and the outcomes of subsequent pregnancies were noted in 48 patients with initial preeclampsia. Ten patients (21%) had a recurrence of preeclampsia, and those with early onset preeclampsia on the first pregnancy were more likely to have a recurrence (non-recurrent, 4 (11%) vs. recurrent, 5 (50%); p = 0.012). Analysis of the MAP in 40 patients showed higher recurrence rates in patients with elevations in MAP during the early second trimester (ΔMAP (early second - first trimester) median: -6 mmHg vs -3.3 mmHg, p = 0.03). Approximately 20% of patients with initial preeclampsia experience recurrence. The timing of onset in the primary pregnancy is an important predictive factor for preeclampsia in subsequent pregnancies.

Our study aims to elucidate the relationship between BP levels upon admission and in-hospital outcomes in patients hospitalized with AF. Based on the Improving Care for Cardiovascular Disease in China-AF (CCC-AF) project, patients hospitalized with AF collected from 236 hospitals in China from 2015 to 2019 were included in current analysis. A total of 60 390 patients hospitalized with AF were included. Using systolic BP (SBP)/diastolic BP (DBP) of 130-139/80-89 mmHg upon admission as the reference, SBP/DBP ≥160/100 mmHg was associated with an increased risk of stroke/transient ischemic attack (TIA) (adjusted OR, 1.65; 95% CI, 1.27-2.15; P < 0.001) and heart failure (HF) (adjusted OR, 1.29; 95% CI, 1.18-1.41; P < 0.001). SBP/DBP < 120/ < 80 mmHg was associated with an increased risk of HF (adjusted OR, 1.24; 95% CI, 1.14-1.34; P < 0.001), and all-cause death (adjusted OR, 1.90; 95% CI, 1.90-3.86; P < 0.001). A similar pattern was observed in the analysis of the relationship between SBP and DBP levels and in-hospital outcomes, respectively. Among patients hospitalized with AF, higher BP levels upon admission are associated with an increased risk of stroke/TIA and HF, and lower BP levels are associated with an increased risk of HF and all-cause death. Hence, physicians should pay attention to higher and lower BP levels.
