Abstract
AIM This study aimed to explore the association between medication literacy and blood pressure control among hypertensive patients. BACKGROUND Blood pressure control is a challenge for global health systems. Medication literacy is essential for medication self-management in hypertensive patients and a basis for managers to develop comprehensive intervention strategies for hypertension medication use. DESIGN A cross-sectional observational study was conducted. METHODS A total of 378 hypertensive patients was selected by convenience sampling from two tertiary hospitals and four community health service centres from December 2021 to January 2022 in Changsha, China. Associations between medication literacy and blood pressure control were identified with chi-square, independent samples t-tests and logistic regression analyses. RESULTS The average medication literacy score of the hypertensive patients investigated was low. Over a third of patients had uncontrolled blood pressure. Logistic regression analysis showed that medication literacy was an influencing factor for blood pressure control rate in hypertensive patients. CONCLUSIONS Medication literacy and blood pressure control among hypertensive patients was poor. Medication literacy was a facilitator of blood pressure control so improving medication literacy may be of value to improve blood pressure control in hypertensive patients.

Abstract
Introduction: Studies have shown positive clinical outcomes in chronic conditions, such as hypertension, through pharmacist-delivered medication therapy management and medication adherence services. Given the need for social distancing during the COVID-19 pandemic, increased utilization of telepharmacy strategies has been employed for managing blood pressure control. Methods: A retrospective single-center cohort study that compared in-person pharmacist visits and telepharmacy visits in primary care patients with hypertension via electronic chart review from January 2018 to July 2022. Subjects were included who were at least 18 years of age with hypertension. Comparator groups were patients who underwent an in-person pharmacy (pre-COVID-19) visit vs a telepharmacy visit (post-COVID-19). The primary outcome was the number of patients with controlled blood pressure based on a blood pressure goal of less than or equal to 130/80 following telepharmacy visit vs in-person visit. Medication adherence, pharmacist intervention, incidence of antihypertensive side-effects, and blood pressure maintenance based on a goal of ≤140/90 were also evaluated. Results: A total of 77 patients were included. There was no difference in the primary outcome following in person pharmacy visits compared to telepharmacy visits (P = .690). There was also no difference found for the secondary endpoints of blood pressure goal less than or equal to 140/90 mmHg (P = .481), medication adherence (P = 1.00), or antihypertensive adverse events (P = .344). Conclusion: Telepharmacy visits had a nonsignificant change in blood pressure control when compared to in-person visits. Results suggest that the utilization of either in-person or telepharmacy strategies benefit the management of hypertension.

Abstract
Systemic hypertension is a strong risk factor for cardiovascular, neurovascular, and renovascular diseases. Central artery stiffness is both an initiator and indicator of hypertension, thus revealing a critical relationship between the wall mechanics and hemodynamics. Mice have emerged as a critical animal model for studying effects of hypertension and much has been learned. Regardless of the specific mouse model, data on changes in cardiac function and hemodynamics are necessarily measured under anesthesia. Here, we present a new experimental-computational workflow to estimate awake cardiovascular conditions from anesthetized data, which was then used to quantify effects of chronic angiotensin II-induced hypertension relative to normotension in wild-type mice. We found that isoflurane anesthesia had a greater impact on depressing hemodynamics in angiotensin II-infused mice than in controls, which led to unexpected results when comparing anesthetized results between the two groups of mice. Through comparison of the awake simulations, however, in vivo relevant effects of angiotensin II-infusion on global and regional vascular structure, properties, and hemodynamics were found to be qualitatively consistent with expectations. Specifically, we found an increased in vivo vascular stiffness in the descending thoracic aorta and suprarenal abdominal aorta, leading to increases in pulse pressure in the distal aorta. These insights allow characterization of the impact of regionally varying vascular remodeling on hemodynamics and mouse-to-mouse variations due to induced hypertension.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) exposure is related to the occurrence of cardiovascular diseases (CVDs). Endothelial dysfunction is considered an initial event of CVDs. To confirm the relationship of PAHs exposure with endothelial dysfunction, 8-week-old male SD rats and primary human umbilical vein endothelial cells (HUVECs) were co-treated with environmental doses of 16 priority-controlled PAHs for 90 d and 48 h, respectively. Results showed that 10× PAHs exposure remarkably raised tumor necrosis factor-α and malonaldehyde levels in rat serum (p < 0.05), but had no effects on interleukin-8 levels and superoxide dismutase activity. The expressions of SIRT1 in HUVECs and rat aorta were attenuated after PAHs treatment. Interestingly, PAHs exposure did not activate the expression of total endothelial nitric oxide synthase (eNOS), but 10× PAHs exposure significantly elevated the expression of phosphorylated eNOS (Ser1177) in HUVECs and repressed it in aortas, accompanied with raised nitrite level both in serum and HUVECs by 48.50-253.70 %. PAHs exposure also led to the augment of endothelin-1 (ET-1) levels by 19.76-38.54 %, angiotensin (Ang II) levels by 20.09-39.69 % in HUVECs, but had no effects on ET-1 and Ang II levels in serum. Additionally, PAHs exposure improved endocan levels both in HUVECs and serum by 305.05-620.48 % and stimulated the THP-1 cells adhered to HUVECs (p < 0.05). After PAHs treatment, the smooth muscle alignment was disordered and the vascular smooth muscle locally proliferated in rat aorta. Notably, the systolic blood pressure of rats exposed to 10× PAHs increased significantly compared with the control ones (131.28 ± 5.20 vs 116.75 ± 5.33 mmHg). In summary, environmental chronic PAHs exposure may result in endothelial dysfunction in SD rats and primary HUVECs. Our research can confirm the cardiovascular damage caused by chronic exposure to PAHs and provide ideas for the prevention or intervention of CVDs affected by environmental factors.

Abstract
OBJECTIVE Although anxiety is known to be associated with elevated blood pressure and hypertension in adults, this has not been studied in children. The aim of this study was to determine the association between anxiety and elevated blood pressures in adolescents. METHODS Adolescents, aged 12-18 years old, referred to the nephrology clinic were eligible to participate. Elevated blood pressure was defined as either SBP or DBP measurement above the 95th percentile for age, height, and sex. Participants were evaluated for anxiety using the validated Screen for Child Anxiety Related Disorders questionnaire filled independently by the child (SCARED-C) and parent (SCARED-P) evaluating the child. RESULTS Two hundred adolescents participated in this study. Thirty-one (53%) of SCARED-P-positive participants were found to have elevated blood pressure compared with 27 (19%) of SCARED-P negative, P 0.03. Twenty-five (43%) of SCARED-P positive had elevated DBP compared with 31 (28%) of SCARED-P negative ( P 0.003). In SCARED-P positive, mean DBP (78.4 ± 9.9) was higher compared with SCARED-P negative (74.9 ± 9.2) ( P 0.03). In a subgroup of adolescents (№ 130) not treated with blood pressure medications mean DBP was higher in both SCARED-P (79.0 ± 10.1) and SCARED-C (77.1 ± 10.4) positive groups compared with SCARED-P (73.6 ± 9.3) and SCARED-C (73 ± 8.9) negative, respectively. CONCLUSION Our study demonstrates an association between anxiety and elevated DBP in adolescent children. Screening adolescents for anxiety should be a part of the routine evaluation of adolescent children.

Abstract
Blood Pressure Variability (BPV) is associated with cardiovascular risk and serum uric acid level. We investigated whether BPV was lowered by allopurinol and whether it was related to neuroimaging markers of cerebral small vessel disease (CSVD) and cognition. We used data from a randomised, double-blind, placebo-controlled trial of two years allopurinol treatment after recent ischemic stroke or transient ischemic attack. Visit-to-visit BPV was assessed using brachial blood pressure (BP) recordings. Short-term BPV was assessed using ambulatory BP monitoring (ABPM) performed at 4 weeks and 2 years. Brain MRI was performed at baseline and 2 years. BPV measures were compared between the allopurinol and placebo groups, and with CSVD and cognition. 409 participants (205 allopurinol; 204 placebo) were included in the visit-to-visit BPV analyses. There were no significant differences found between placebo and allopurinol groups for any measure of visit-to-visit BPV. 196 participants were included in analyses of short-term BPV at week 4. Two measures were reduced by allopurinol: the standard deviation (SD) of systolic BP (by 1.30 mmHg (95% confidence interval (CI) 0.18-2.42, p = 0.023)); and the average real variability (ARV) of systolic BP (by 1.31 mmHg (95% CI 0.31-2.32, p = 0.011)). There were no differences in other measures at week 4 or in any measure at 2 years, and BPV was not associated with CSVD or cognition. Allopurinol treatment did not affect visit-to-visit BPV in people with recent ischemic stroke or TIA. Two BPV measures were reduced at week 4 by allopurinol but not at 2 years.

Abstract
The GSTT1 and GSTM1 genes have a role in mercury metabolism and excretion, as well as blood pressure response, impacting birth outcomes. The present study assesses whether GSTT1 and GSTM1 deletion variants and maternal hair Hg concentration are associated with blood pressure and birth outcomes among the Indonesian coastal pregnant mother population. A cross-sectional study was conducted on 139 pregnant women in the Jepara coastal area of Central Java, Indonesia. Maternal characteristics during pregnancy, including blood pressure and birth outcomes, were collected. GSTT1 and GSTM1 gene variants were detected using polymerase chain reaction (PCR). Hair Hg levels were measured using the reducing-vaporization mercury analyzer. The mean maternal hair Hg concentration was 0.727±0.558 μg/g. GSTT1 genotype homozygous deletion was found in 41.7% of subjects, while no GSTM1 deletion was found. No statistically significant difference was found between deletion and non-deletion groups for hair Hg. GSTT1 deletion genotype shows protection but is inconclusive toward diastolic hypertension (p=0.048, OR 0.285, CI 0.077-1.052) and insignificant with birth outcomes (all p>0.05). High hair Hg concentration and positive history of cardiovascular diseases increase the risk of systolic and diastolic hypertension during pregnancy with OR 6.871 (CI 95% 1.445-32.660) and 8.518 (CI 95% 2.126-34.125), respectively, while not in birth outcomes. Maternal Hg exposure and history of cardiovascular diseases are independent risk factors for pregnant hypertension, whereas the GSTT1 homozygous deletion genotype has no role in diastolic hypertension and birth outcomes among the Indonesian coastal pregnant mother population.

Abstract
Dynamic preload parameters are used to guide perioperative fluid management. However, reported cut-off values vary and the presence of a gray zone complicates clinical decision making. Measurement error, intrinsic to the calculation of pulse pressure variation (PPV) has not been studied but could contribute to this level of uncertainty. The purpose of this study was to quantify and compare measurement errors associated with PPV calculations. Hemodynamic data of patients undergoing liver transplantation were extracted from the open-access VitalDatabase. Three algorithms were applied to calculate PPV based on 1 min observation periods. For each method, different durations of sampling periods were assessed. Best Linear Unbiased Prediction was determined as the reference PPV-value for each observation period. A Bayesian model was used to determine bias and precision of each method and to simulate the uncertainty of measured PPV-values. All methods were associated with measurement error. The range of differential and proportional bias were [- 0.04%, 1.64%] and [0.92%, 1.17%] respectively. Heteroscedasticity influenced by sampling period was detected in all methods. This resulted in a predicted range of reference PPV-values for a measured PPV of 12% of [10.2%, 13.9%] and [10.3%, 15.1%] for two selected methods. The predicted range in reference PPV-value changes for a measured absolute change of 1% was [- 1.3%, 3.3%] and [- 1.9%, 4%] for these two methods. We showed that all methods that calculate PPV come with varying degrees of uncertainty. Accounting for bias and precision may have important implications for the interpretation of measured PPV-values or PPV-changes.

Abstract
Progresa, an anti-poverty conditional cash transfer program, has been a model for similar programs in more than 60 countries. Numerous studies have found positive impacts on schooling, the nutritional and health status of children and adolescents, and household consumption. However, the effects on the health of older adult beneficiaries have been particularly understudied. In this paper we analyze the effects of Progresa on middle-aged and older adult health, focusing on a high prevalence chronic condition: hypertension. Our results show that Progresa had significant benefits in terms of improved hypertension diagnosis and use of treatment drugs. However, we did not find significant changes in uncontrolled hypertension as measured by systolic and diastolic blood pressure biomarkers in household survey data. Thus, while cash transfer programs may facilitate financial access to healthcare visits and the ability to buy prescribed medicines, by itself the program might not improve hypertension outcomes without complementary healthcare system follow-up to ensure dosage titration and medication adherence.

Abstract
BACKGROUND AND OBJECTIVE Vital sign monitoring in the Intensive Care Unit (ICU) is crucial for enabling prompt interventions for patients. This underscores the need for an accurate predictive system. Therefore, this study proposes a novel deep learning approach for forecasting Heart Rate (HR), Systolic Blood Pressure (SBP), and Diastolic Blood Pressure (DBP) in the ICU. METHODS We extracted 24,886 ICU stays from the MIMIC-III database which contains data from over 46 thousand patients, to train and test the model. The model proposed in this study, Transformer-based Diffusion Probabilistic Model for Sparse Time Series Forecasting (TDSTF), merges Transformer and diffusion models to forecast vital signs. The TDSTF model showed state-of-the-art performance in predicting vital signs in the ICU, outperforming other models' ability to predict distributions of vital signs and being more computationally efficient. The code is available at https://github.com/PingChang818/TDSTF. RESULTS The results of the study showed that TDSTF achieved a Standardized Average Continuous Ranked Probability Score (SACRPS) of 0.4438 and a Mean Squared Error (MSE) of 0.4168, an improvement of 18.9% and 34.3% over the best baseline model, respectively. The inference speed of TDSTF is more than 17 times faster than the best baseline model. CONCLUSION TDSTF is an effective and efficient solution for forecasting vital signs in the ICU, and it shows a significant improvement compared to other models in the field.

Abstract
BACKGROUND Controversy exists whether blood pressure augmentation therapy benefits patients suffering from spinal cord injury (SCI). This retrospective comparative study was designed to assess the impact of two different mean arterial pressure (MAP) targets (85-90 mmHg vs. 65-85 mmHg) on neurological recovery after traumatic cervical SCI. METHODS Fifty-one adult patients with traumatic cervical SCI were retrospectively divided into two groups according to their intensive care unit (ICU) MAP targets: 85-90 mmHg (higher MAP group, n = 32) and 65-85 mmHg (lower MAP group, n = 19). Invasive MAP measurements were stored as 2-min median values for 3-7 days. The severity of SCI (AIS grade and neurological level) was evaluated upon ICU stay and during rehabilitation. Neurological recovery was correlated with individual mean MAP values and with the proportion of MAP values ≥85 mmHg upon the first 3 days (3d-MAP%≥85 ). RESULTS The initial AIS grades were A 29.4%, B 17.6%, C 31.4%, and D 21.6%. AIS grade improved in 24 patients (47.1%). During ICU care, 82.0% and 36.8% of the measured MAP values reached ≥85 mmHg in the higher and the lower MAP groups, respectively (p < .001). The medians of individual mean MAP values were different between the groups (90.2 mmHg vs. 81.4 mmHg, p < .001). Similarly, 3d-MAP%≥85 was higher in the higher MAP group (85.6% vs. 50.0%, p < .001). However, neurological recovery was not different between the groups, nor did it correlate with individual mean MAP values or 3d-MAP%≥85 . CONCLUSION The currently recommended MAP target of 85-90 mmHg was not associated with improved outcomes compared to a lower target in patients with traumatic cervical SCI in this cohort.

Abstract
Immunoglobulin A (IgA) nephropathy is the most frequent glomerulonephritis in adults in Central Europe. It is characterized by microhematuria and occasionally macrohematuria, proteinuria and a chronic loss of kidney function. The diagnosis is made based on a kidney biopsy. The progressive kidney damage must always be slowed down by normalizing blood pressure, using angiotensin inhibitors and consistently avoiding additional toxic substances. In many cases this is not sufficient and then sodium-glucose transporter 2 (SGLT-2) inhibitors and immunomodulators are used. In particular, the SGLT-2 inhibitors show a very significant reduction in proteinuria and slow down the deterioration of the estimated glomerular filtration rate (eGFR). While systemic corticosteroids are now only indicated in rare cases, a special budesonide formulation shows good effects. Further pathophysiologically based pharmacotherapies are currently being tested in clinical studies. These include, among others, the dual endothelin type A receptor and angiotensin II receptor antagonist sparsentan, which has already been shown to reduce proteinuria as well as inhibitors of complement activation, which is important for kidney damage. Initial findings for these as well as for the B‑lymphocyte proliferation inhibitor sibeprenlimab, suggest that they could enrich the armamentarium for the treatment of IgA nephropathy in the future.

Abstract
BACKGROUND There is limited evidence to inform the association between the intake of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin II receptor blockers (ARBs) and intraoperative blood pressure (BP) changes in an ambulatory surgery population. METHODS Adult patients who underwent ambulatory surgery and were discharged on the same day or within 24 hours of their procedure were enrolled in this prospective cohort study. The primary outcome of the study was early intraoperative hypotension (first 15 minutes of induction). Secondary outcomes included any hypotension, BP variability, and recovery. Hypotension was defined as a decrease in systolic BP of >30% from baseline for ≥5 minutes or a mean BP of <55 mm Hg. Four exposure groups were compared (no antihypertensives, ACEI/ARB intake <10 hours before surgery, ACEI/ARB intake ≥10 hours before surgery, and other antihypertensives). RESULTS Of the 537 participants, early hypotension was observed in 25% (n = 134), and any hypotension in 41.5% (n = 223). Early hypotension occurred in 30% (29 of 98) and 41% (17 of 41) with the intake of ACEI/ARBs <10 and ≥10 hours before surgery, respectively, compared to 30% (9 of 30) with other antihypertensives and 21% (79 of 368) with no antihypertensives ( P = .02). Those on antihypertensives also experienced any hypotension more frequently than those who were not on antihypertensives ( P < .001). After adjusting for age and baseline BP in a regression analysis, antihypertensive exposure groups were observed to be associated only with any intraoperative hypotension ( P = .012). In the ACEI/ARB subset, there was no evidence of an association between time since the last ACEI/ARB dose, and hypotension or minimum mean or systolic BP. Compared to normal baseline BP, BP ≥ 140/90 mm Hg increased the odds of early and any hypotension (odds ratio [OR], 3.9; 95% confidence interval [CI], 2.1-7.1 and OR, 7.7; 95% CI, 3.7-14.9, respectively; P < .001). Intraoperative variability in systolic and diastolic BP demonstrated significant differences with age, baseline BP, and antihypertensive exposure group ( P < .001). CONCLUSIONS Early and any hypotension occurred more frequently in those on antihypertensives than those not on antihypertensives. Unadjusted associations between antihypertensive exposure and intraoperative hypotension were largely explained by baseline hypertension rather than the timing of ACEI/ARBs or type of antihypertensive exposure. Patients with hypertension and on treatment experience more intraoperative BP variability and should be monitored appropriately.

Abstract
Globally, people living with HIV on antiretroviral therapy have an increased risk of cardiovascular disease. Hypertension is the most important preventable risk factor for cardiovascular disease and is associated with increased morbidity. We conducted an exploratory survey with hypertensive persons living with HIV who received integrated HIV and hypertension care in a large clinic in Uganda between August 2019 and March 2020 to determine factors associated with blood pressure control at six months. Controlled blood pressure was defined as <140/90 mmHg. Multivariable logistic regression was used to determine baseline factors associated with blood pressure control after 6 months of antihypertensive treatment. Of the 1061 participants, 644 (62.6%) were female. The mean age (SD) was 51.1 (9.4) years. Most participants were overweight (n = 411, 38.7%) or obese (n = 276, 25.9%), and 98 (8.9%) had diabetes mellitus. Blood pressure control improved from 14.4% at baseline to 66.1% at 6 months. Comorbid diabetes mellitus (odds ratio (OR) = 0.41, 95% confidence interval (CI) = 0.26-0.64, p < 0.001) and HIV status disclosure (OR = 0.73, 95% CI = 0.55-0.98, p = 0.037) were associated with the absence of controlled blood pressure at 6 months. In conclusion, comorbid diabetes mellitus and the disclosure of an individual's HIV status to a close person were associated with poor blood pressure control among persons living with HIV who had hypertension. Therefore, subpopulations of persons living with HIV with hypertension and comorbid diabetes mellitus may require more thorough assessments and intensive antihypertensive management approaches to achieve blood pressure targets.

Abstract
The aim of this study was to investigate if mortality during a 13-year follow-up varied between normotensive subjects, screen-detected hypertensive subjects, and subjects with antihypertensive medication at baseline. A population-based screening and intervention program identified 2659 apparently healthy, middle-aged cardiovascular-risk persons in southwestern Finland. Screen-detected hypertension was verified by home blood pressure measurements. Lifestyle counseling was provided for all participants and preventive medications were started or intensified if needed. All-cause and cardiovascular mortality were obtained from the official statistics. Screen-detected hypertension was diagnosed in 17% of the participants, 51% were normotensive and 32% had antihypertensive medication at baseline. The screen-detected hypertensives had higher mean blood pressure and cholesterol levels than the two other groups. Altogether 289 subjects died during the follow-up, 83 (29%) from cardiovascular disease. Those with screen-detected hypertension had decreased cardiovascular mortality risk compared to the medicated hypertensives [sHR 0.40 (95% CI: 0.19 to 0.88, p = 0.023)], and comparable with that of the normotensives [sHR 0.53 (95% CI: 0.24 to 1.15)]. Newly diagnosed diabetes at baseline was a powerful predictor of cardiovascular mortality [sHR 2.71 (95% CI: 1.57 to 4.69)]. Early detection of hypertension and timely multifactorial intervention seem to be important in preventing hypertension-related mortality.

Abstract
In this paper, we propose a general framework to select tuning parameters for the nonparametric derivative estimation. The new framework broadens the scope of the previously proposed generalizedC p $C_p$ criterion by replacing the empirical derivative with any other linear nonparametric smoother. We provide the theoretical support of the proposed derivative estimation in a random design and justify it through simulation studies. The practical application of the proposed framework is demonstrated in the study of the age effect on hippocampal gray matter volume in healthy adults from the IXI dataset and the study of the effect of age and body mass index on blood pressure from the Pima Indians dataset.

Abstract
PURPOSE Intermittent pneumatic compression (IPC) applies gradual pressure to facilitate lymph and blood flow movement to reduce exercise-induced tissue fluid accumulation and plasma volume loss. This study aimed to evaluate the cardiovascular system response during the recovery with IPC compared with passive recovery (Sham). METHODS Sixteen volunteers (7 females and 9 males) executed a cycling-based exhausting sprint interval exercise (8 × 20 s all out), followed by a 30-min IPC or Sham condition. Participants performed two trials in a randomised, counterbalanced, and crossover design. Several cardiovascular parameters (blood pressure, heart function, and peripheral vascular resistance) were recorded at baseline (5'), through the recovery protocol (30'), and afterwards (5'). RESULTS The use of IPC during the recovery phase led to a faster recovery, stated in relative values to pre-exercise, in mean blood pressure (102.5 ± 19.3% vs. 92.7 ± 12.5%; P < 0.001), and cardiac output (139.8 ± 30.0% vs. 146.2 ± 40.2%; P < 0.05) in comparison to Sham condition. Furthermore, during the IPC-based recovery, there was a slower recovery in cardiac pressure change over time (92.5 ± 25.8% vs. 100.5 ± 48.9%; P < 0.05), and a faster return to pre-exercise values in the peripheral vascular resistance (75.2 ± 25.5% vs. 64.8 ± 17.4%; P < 0.001) compared to Sham. CONCLUSION The application of IPC after high-intensity exercise promotes the recovery of the cardiovascular system, reducing cardiovascular strain. Future investigations should consider the effects on the sympathetic-parasympathetic balance, such as heart rate variability, to assess further bonds between the use of IPC and autonomous control.

Abstract
There is still much uncertainty surrounding the approach to diagnosing and managing a sport-related concussion (SRC). Neurobiological recovery may extend beyond clinical recovery following SRC, highlighting the need for objective physiological parameters to guide diagnosis and management. With an increased understanding of the connection between the heart and the brain, the utility of assessing cardiovascular functioning following SRC has gained attention. As such, this review focuses on the assessment of cardiovascular parameters in the context of SRC. Although conflicting results have been reported, decreased heart rate variability, blood pressure variability, and systolic (ejection) time, in addition to increased spontaneous baroreflex sensitivity and magnitude of atrial contraction have been shown in acute SRC. We propose that these findings result from the neurometabolic cascade triggered by a concussion and represent alterations in myocardial calcium handling, autonomic dysfunction, and an exaggerated compensatory response that attempts to maintain homeostasis following a SRC. Assessment of the cardiovascular system has the potential to assist in diagnosing and managing SRC, contributing to a more comprehensive and multimodal assessment strategy.

Abstract
Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are invasive techniques used to evaluate the hemodynamic significance of coronary artery stenosis. These methods have been validated through perfusion imaging and clinical trials. New invasive pressure ratios that do not require hyperemia have recently emerged, and it is essential to confirm their diagnostic efficacy. The aim of this study was to validate the resting full-cycle ratio (RFR) and the diastolic pressure ratio (dPR), against [15O]H2O positron emission tomography (PET) imaging. A total of 129 symptomatic patients with an intermediate risk of coronary artery disease (CAD) were included. All patients underwent cardiac [15O]H2O PET with quantitative assessment of resting and hyperemic myocardial perfusion. Within a 2 week period, coronary angiography was performed. Intracoronary pressure measurements were obtained in 320 vessels and RFR, dPR, and FFR were computed. PET derived regional hyperemic myocardial blood flow (hMBF) and myocardial perfusion reserve (MPR) served as reference standards. In coronary arteries with stenoses (43%, 136 of 320), the overall diagnostic accuracies of RFR, dPR, and FFR did not differ when PET hyperemic MBF < 2.3 ml min-1 (69.9%, 70.6%, and 77.1%, respectively) and PET MPR < 2.5 (70.6%, 71.3%, and 66.9%, respectively) were considered as the reference for myocardial ischemia. Non-significant differences between the areas under the receiver operating characteristic (ROC) curve were found between the different indices. Furthermore, the integration of FFR with RFR (or dPR) does not enhance the diagnostic information already achieved by FFR in the characterization of ischemia via PET perfusion. In conclusion, the novel non-hyperemic pressure ratios, RFR and dPR, have a diagnostic performance comparable to FFR in assessing regional myocardial ischemia. These findings suggest that RFR and dPR may be considered as an FFR alternative for invasively guiding revascularization treatment in symptomatic patients with CAD.

Abstract
Mechanical loads on the polymeric fibers of oxygenating bundles are commonly present due to bundle press-fitting during device assembly and blood pressure load. However, computational fluid dynamics (CFD) simulations for fiber bundle optimization neglect possible changes in microstructure due to such deformations. The aim of this study is to investigate the impact of fiber deformability on bundle microstructure and fluid dynamics mainly in terms of permeability. Fibers from commercial mats typically used for blood oxygenators were mechanically tested and based on these experimental data, a material model was developed to simulate the structural deformations the fibers undergo under press-fitting and blood pressure loads. Then, CFD simulations were performed on deformed bundle repetitive units to investigate permeability under varying loading conditions. The effects of different bundle geometric parameters on the variation of bundle permeability due to press-fitting were evaluated. Bundle press-fitting results in significant changes in microstructure that are reflected in a bundle permeability more than halved for a 15% press-fitting. This impact on permeability is present in all the simulated fiber bundles and becomes more pronounced as the pitch between fibers and thus bundle porosity decreases. Instead, the analyses on pressurized bundle show only small deformations caused by pressure load, with permeability changes below 1%. While blood pressure effects could be neglected, bundle press-fitting turns out to have a significant impact on bundle microstructure and permeability. Neglecting such microstructure variations during CFD simulations could also lead to incorrect assessment of the local fluid dynamics within the bundle.

Abstract
OBJECTIVE To describe the prevalence of maternal chronic hypertension (MCH), assess how frequently blood pressure is controlled before pregnancy among those with MCH, and explore management practices for antihypertensive medications (AHM) during the pre-pregnancy and pregnancy periods. DATA SOURCES, STUDY SETTING, AND STUDY DESIGN We conducted a descriptive observational study using data abstracted from the Veterans Health Administration (VA) inclusive of approximately 11 million Veterans utilizing the VA in fiscal years 2010-2019. DATA COLLECTION/EXTRACTION METHODS Veterans aged 18-50 were included if they had a diagnosis of chronic hypertension before a documented pregnancy in the VA EMR. We identified chronic hypertension and pregnancy with diagnosis codes and defined uncontrolled blood pressure as ≥140/90 mm Hg on at least one measurement in the year before pregnancy. Sensitivity models were conducted for individuals with at least two blood pressure measurements in the year prior to pregnancy. Multivariable logistic regression explored the association of covariates with recommended and non-recommended AHMs received 0-6 months before pregnancy and during pregnancy. PRINCIPAL FINDINGS In total, 8% (3767/46,178) of Veterans with a documented pregnancy in VA data had MCH. Among 2750 with MCH meeting inclusion criteria, 60% (n = 1626) had uncontrolled blood pressure on at least one BP reading and 31% (n = 846) had uncontrolled blood pressure on at least two BP readings in the year before pregnancy. For medications, 16% (n = 437) received a non-recommended AHM during pregnancy. Chronic kidney disease (OR = 3.2; 1.6-6.4) and diabetes (OR = 2.3; 1.7-3.0) were most strongly associated with use of a non-recommended AHM during pregnancy. CONCLUSIONS Interventions are needed to decrease the prevalence of MCH, improve preconception blood pressure control, and ensure optimal pharmacologic antihypertensive management among Veterans of childbearing potential.

Abstract
OBJECTIVE To validate the ANDON KD-595 automated upper-arm blood pressure monitor for clinical use and self-measurement blood pressure measurement according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard. METHODS Same left-arm blood pressure was sequentially measured in 90 qualified adult participants and compared with a standard mercury sphygmomanometer. A total of 270 comparison pairs were obtained and analyzed according to the universal standard. RESULTS For the validation Criterion 1 of the universal standard, the mean ± SD of the differences between the test device and reference blood pressure readings was 0.96 ± 5.35 and 0.82 ± 5.08 mmHg for SBP and DBP, respectively. For Criterion 2, the SDs of the averaged blood pressure differences between the test device and reference blood pressure per subject were 4.84 and 4.64 mmHg (with maximum allowed SDs of 6.87 and 6.89 mmHg) for SBP and DBP, respectively. CONCLUSION The ANDON KD-595 automated upper-arm blood pressure monitor passed all the validation requirements according to the AAMI/ESH/ISO Universal Standard and can be recommended for clinical use and self-measurement blood pressure measurement in the general population.

Abstract
The association of hypertension and diabetes mellitus is extremely common, increasing the mortality risk of patients, mainly by cardiovascular causes. Regarding the blood pressure (BP) targets to be achieved, most guidelines suggest levels of 130 mmHg for SBP and of 80 mmHg for DBP. Dietary modifications are quite effective, and many studies suggest that decreasing sodium intake and increasing potassium ingestion are both valuable practices for reducing BP. This can be achieved by stimulating the ingestion of lacteous products, vegetables, and nuts. As for the ideal pharmacologic treatment for hypertension, either calcium channel blockers, diuretics or angiotensin-system blockers can be the first class of drug to be used. In this review, we summarize the evaluation of patients with diabetes mellitus and hypertension, and discuss the available therapeutic approaches, with emphasis on evidence-based dietary recommendations.

Abstract
Previous studies reported that iron may have an indispensable role in the risk of hypertension (HTN). However, the result of the studies on the relationship between iron and risk of HTN is inconsistent. This study aimed to assess the association between the association of dietary iron intake and HTN in the Iranian population. This case-control study was conducted on 4184 people aged 35 to 70, including 1239 people with HTN and 2945 people with normal blood pressure (BP) in Sabzevar, Iran. Dietary intake was assessed using a food frequency questionnaire (FFQ). The Nutritionist IV software was used in terms of the assessment of dietary intake of iron. An inverse association was found between iron intake and HTN (OR = 0.97, CI 95%: 0.94-0.99, P = 0.04). The association remained significant after adjustment for age, gender, smoking, drinking alcohol, calorie intake, and BMI (OR = 0.94, CI 95%: 0.89-0.98, P = 0.01). As a conclusion, iron intake was inversely associated with HTN. Further longitudinal studies on the effect of iron intake on BP are required to confirm this finding.

Abstract
Raised blood pressure is the leading risk factor for cardiovascular diseases. We aimed to demonstrate the effectiveness of a 3-year community-based healthy lifestyle promotion intervention at a neighbourhood level for blood pressure reduction among adults in the context of a political transition. We conducted repeated cross-sectional surveys including 1880 (940 from each area) participants at baseline and 1977 (1001 in the intervention area; 976 comparison area) participants at follow-up. Data collection was conducted through home visits. Multiple linear regression models were used to identify the intervention effect and factors associated with blood pressure change in each area. The prevalence of hypertension was 4.4% lower (35.8% vs. 31.4%) in the intervention area after 3 years (p = 0.044). The mean systolic and diastolic blood pressures changed significantly in the intervention area, from 132.4 ± 19.2 mmHg at baseline to 130.6 ± 17.7 mmHg at follow-up (p = 0.035) and from 78.7 ± 11.8 mmHg to 76.9 ± 11.1 mmHg (p < 10-3), respectively. In the control group, the mean systolic blood pressure increased from 129.4 ± 17.8 mmHg to 130.4 ± 17.9 mmHg (p = 0.38). A significant protective effect of the intervention on systolic (β = -0.4; 95% CI: -0.76; -0.06) and diastolic blood pressures (β = -0.22; 95% CI: -0.38; -0.07) was found in the intervention area. In the control area, the effect was not significant for systolic blood pressure. Lifestyle intervention at the neighbourhood level, in the context of a sociopolitical transition, was found to be effective for reducing blood pressure in Sousse, Tunisia. This approach could be scaled up and applied in other similar settings. Future research also needs to focus on designing, implementing, and evaluating multisectoral action plans and legislative measures.

Abstract
Hypertension in children with neuroblastoma is uncommon and can be difficult to control due to the potential for multiple underlying causes. We present the case of a pediatric patient with high-grade neuroblastoma which was complicated by hypertensive emergency. The patient had imaging suggestive of renal artery compression, as well as significantly elevated normetaphrine levels. Multiple anti-hypertensive agents, including an angiotensin converting enzyme inhibitor, α- and β-adrenergic receptor blockers, and a tyrosine hydroxylase inhibitor, were initiated prior to tumor excision. While her blood pressure improved during the post-operative period, she continued to require multiple antihypertensive medications due to residual tumor burden. In this report, we highlight the importance of careful, multidisciplinary management to avoid peri-operative complications in patients with catecholamine-producing tumors.

Abstract
OBJECTIVE Statins appear to have greater antihypertensive effects in observational studies than in randomized controlled trials. This study assessed whether more frequent treatment of hypertension contributed to better blood pressure (BP, mmHg) control in statin-treated than statin-eligible untreated adults in observational studies. METHODS National Health and Nutrition Examination Surveys 2009-2020 data were analyzed for adults 21-75 years ( N = 3814) with hypertension (BP ≥140/≥90 or treatment). The 2013 American College of Cardiology/American Heart Association Cholesterol Guideline defined statin eligibility. The main analysis compared BP values and hypertension awareness, treatment, and control in statin-treated and statin-eligible but untreated adults. Multivariable logistic regression was used to assess the association of statin therapy to hypertension control and the contribution of antihypertensive therapy to that relationship. RESULTS Among adults with hypertension in 2009-2020, 30.3% were not statin-eligible, 36.9% were on statins, and 32.8% were statin-eligible but not on statins. Statin-treated adults were more likely to be aware of (93.4 vs. 80.6%) and treated (91.4 vs. 70.7%) for hypertension than statin-eligible adults not on statins. The statin-treated group had 8.3 mmHg lower SBP (130.3 vs. 138.6), and 22.8% greater control (<140/<90: 69.0 vs. 46.2%; all P values <0.001). The association between statin therapy and hypertension control [odds ratio 1.94 (95% confidence interval 1.53-2.47)] in multivariable logistic regression was not significant after also controlling for antihypertensive therapy [1.29 (0.96-1.73)]. CONCLUSION Among adults with hypertension, statin-treated adults have lower BP and better control than statin-eligible untreated adults, which largely reflects differences in antihypertensive therapy.

Abstract
BACKGROUND Aspiration thrombectomy has gained popularity in patients with massive and sub-massive pulmonary embolism (PE) and having contraindications to thrombolysis. METHODS A meta-analysis was conducted including studies on aspiration thrombectomy in patients with high-risk and intermediate-risk PE. The pooled odds ratio for efficacy parameters, including change in heart rate, blood pressure and right ventricle/left ventricle (RV/LV) ratio, and safety parameters including major bleeding and stroke, was calculated using a random effects model. RESULTS The meta-analysis of 24 selected studies revealed that intermediate and high-risk pulmonary embolism (PE) patients demonstrated significant improvements: modified Miller score odds ratio of 10.60, mean pulmonary artery pressure reduction by 0.04 mm Hg, and an overall all-cause mortality odds ratio of 0.10. Considerable heterogeneity was observed in various outcomes. CONCLUSION Aspiration thrombectomy has success rates in both high-risk and intermediate-risk PE, however, procedural risks, including bleeding, must be anticipated.

Abstract
Blood pressure is regulated by vascular resistance and intravascular volume. However, exchanges of electrolytes and water between intra and extracellular spaces and filtration of fluid and solutes in the capillary beds blur the separation between intravascular, interstitial and intracellular compartments. Contemporary paradigms of microvascular exchange posit filtration of fluids and solutes along the whole capillary bed and a prominent role of lymphatic vessels, rather than its venous end, for their reabsorption. In the last decade, these concepts have stimulated greater interest in and better understanding of the lymphatic system as one of the master regulators of interstitial volume homeostasis. Here, we describe the anatomy and function of the lymphatic system and focus on its plasticity in relation to the accumulation of interstitial sodium in hypertension. The pathophysiological relevance of the lymphatic system is exemplified in the kidneys, which are crucially involved in the control of blood pressure, but also hypertension-mediated cardiac damage. Preclinical modulation of the lymphatic reserve for tissue drainage has demonstrated promise, but has also generated conflicting results. A better understanding of the hydraulic element of hypertension and the role of lymphatics in maintaining fluid balance can open new approaches to prevent and treat hypertension and its consequences, such as heart failure.

Abstract
Individuals with low levels of vitamin D are associated with cardiovascular risks, such as elevated blood pressure (BP), and are; therefore, more likely to develop hypertension. Patients with vitamin D deficiency may face an increased risk of cardiovascular events. In this study, a multicenter, cross-sectional, and school-based investigation was conducted as part of the ERICA project. The sample comprised 1152 adolescents aged 12-17 years from 4 Brazilian cities. Anthropometric variables, BP measurements, and hydroxyvitamin D concentrations were assessed. A 2-level linear regression was fitted to examine the relationship between each level of BP and independent variables. Our findings indicate that movement behaviors were not associated with BP levels, with the exception of sleep time, which demonstrated a positive association. However, after adjustment, this association was found to be nonsignificant. Our study's mediation analysis revealed that vitamin D mediates up to 12.9% of the association between physical activity and systolic BP. Vitamin D is inversely associated with BP in adolescents. In addition to mediating the physical activity and systolic BP association, engaging in physical activity, particularly outdoors, can provide a dual benefit for adolescents by increasing serum vitamin D levels and assisting in the control of BP levels.

Abstract
Effect of vitamin D level on incident hypertension was not elucidated in our country perspective. The objective of the study was to report the level of vitamin D and its relation with incident hypertension among the Bangladeshi adults. This cross-sectional assessment was conducted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh for a period of one year (1st January 2019 to 31st December 2019). A total of 187 participants who had no known history of hypertension and comorbidities were included. Vitamin D assay and risk factors assessment for hypertension were performed for each patient. Data collection was done using a structured questionnaire and the study was conducted in compliance with current declaration of Helsinki. Analysis was conducted with SPSS 26.0. Out of 187 participants 33(17.6%) was newly diagnosed with hypertension. Predominant age group was 31-40 years (30.5%) and the average of incidence ±SD was 36.76±12.14 years. Sufficient, insufficient and deficient vitamin D was present in 11.8%, 32.6% and 55.6% cases, respectively. Mean±SD SBP and DBP were 117.41±12.84 and 76.87±9.46 mm of Hg. Hypertension was significantly more common in male than female (p=0.047), but there was no association of vitamin D with hypertension (p=0.262). Both hypertensive and normotensive patients shared similar risk factor profile in terms of age, gender, BMI, unhealthy food habit, extra salt intake, tobacco use, caffeine consumption, hormonal contraceptive of female (p>0.05 for all). Nearly one-fifth participants had newly diagnosed hypertension and more than fifty percent had vitamin D deficiency. However, vitamin D level didn't have any statistically significant association with incident hypertension.

Abstract
The aim was to evaluate the effects of renal denervation (RDN) on autoregulation of renal hemodynamics and the pressure-natriuresis relationship in Ren-2 transgenic rats (TGR) with aorto-caval fistula (ACF)-induced heart failure (HF). RDN was performed one week after creation of ACF or sham-operation. Animals were prepared for evaluation of autoregulatory capacity of renal blood flow (RBF) and glomerular filtration rate (GFR), and of the pressure-natriuresis characteristics after stepwise changes in renal arterial pressure (RAP) induced by aortic clamping. Their basal values of blood pressure and renal function were significantly lower than with innervated sham-operated TGR (p < 0.05 in all cases): mean arterial pressure (MAP) (115 ± 2 vs. 160 ± 3 mmHg), RBF (6.91 ± 0.33 vs. 10.87 ± 0.38 ml.min-1.g-1), urine flow (UF) (11.3 ± 1.79 vs. 43.17 ± 3.24 µl.min-1.g-1) and absolute sodium excretion (UNaV) (1.08 ± 0.27 vs, 6.38 ± 0.76 µmol.min-1.g-1). After denervation ACF TGR showed improved autoregulation of RBF: at lowest RAP level (80 mmHg) the value was higher than in innervated ACF TGR (6.92 ± 0.26 vs. 4.54 ± 0.22 ml.min-1.g-1, p < 0.05). Also, the pressure-natriuresis relationship was markedly improved after RDN: at the RAP of 80 mmHg UF equaled 4.31 ± 0.99 vs. 0.26 ± 0.09 µl.min-1.g-1 recorded in innervated ACF TGR, UNaV was 0.31 ± 0.05 vs. 0.04 ± 0.01 µmol min-1.g-1 (p < 0.05 in all cases). In conclusion, in our model of hypertensive rat with ACF-induced HF, RDN improved autoregulatory capacity of RBF and the pressure-natriuresis relationship when measured at the stage of HF decompensation.

Abstract
OBJECTIVE To evaluate the efficacy and safety of pharmacogenomics (PGx)-guided treatment in individuals with resistant hypertension (RH). STUDY DESIGN Randomised controlled open-label study. Place and Duration of the Study: Department of Cardiology, The First Hospital of China Medical University, Shenyang, Liaoning Province, China, from June 2019 to November 2021. METHODOLOGY The study assigned RH patients to two groups. The intervention group (IG) received 12 weeks of PGx-guided treatment, while the control group (CG) followed a consensus-based approach. Examining 10 genes and their alleles with 31 antihypertensive drugs in the IG, the study provided specific medication advice. The primary outcome measured the difference in office systolic blood pressure (SBP) change from baseline at 12 weeks. Secondary outcomes included changes in diastolic blood pressure (DBP), hepatic and renal function, and major adverse cardiovascular events. RESULTS Fifty-nine patients from the First Hospital of China Medical University participated, with 29 in the IG and 30 in the CG. Significant differences were noted in SBP reduction (IG: 31.26 ± 18.64 mmHg; CG: 14.61 ± 17.74 mmHg; p=0.001) and DBP reduction (IG: 19.61 ± 17.32 mmHg; CG: 7.81 ± 11.23 mmHg; p = 0.003) after 12 weeks. One IG patient had a heart attack, and one CG subject developed heart failure. At week 12, hepatic insufficiency was observed in one IG patient and six CG patients, while renal insufficiency occurred in five patients of both groups. CONCLUSION Treatment guided by PGx demonstrated significant reductions in both SBP and DBP compared to consensus-based treatment.

Abstract
Restoring ischaemic myocardial tissue perfusion is crucial for minimizing infarct size. Acute mechanical left ventricular (LV) support has been suggested to improve infarct tissue perfusion. However, its regulatory mechanism remains unclear. We investigated the physiological mechanisms in six Yorkshire pigs, which were subjected to 90-min balloon occlusion of the left anterior descending artery. During the acute reperfusion phase, LV support using an Impella heart pump was initiated. LV pressure, coronary flow and pressure of the infarct artery were simultaneously recorded to evaluate the impact of LV support on coronary physiology. Coronary wave intensity was calculated to understand the forces regulating coronary flow. Significant increases in coronary flow velocity and its area under the curve were found after mechanical LV support. Among the coronary flow-regulating factors, coronary pressure was increased mainly during the late diastolic phase with less pulsatility. Meanwhile, LV pressure was reduced throughout diastole resulting in significant and consistent elevation of coronary driving pressure. Interestingly, the duration of diastole was prolonged with LV support. In the wave intensity analysis, the duration between backward suction and pushing waves was extended, indicating that earlier myocardial relaxation and delayed contraction contributed to the extension of diastole. In conclusion, mechanical LV support increases infarct coronary flow by extending diastole and augmenting coronary driving pressure. These changes were mainly driven by reduced LV diastolic pressure, indicating that the key regulator of coronary flow under mechanical LV support is downstream of the coronary artery, rather than upstream. Our study highlights the importance of LV diastolic pressure in infarct coronary flow regulation. KEY POINTS: Restoring ischaemic myocardial tissue perfusion is crucial for minimizing infarct size. Although mechanical left ventricular (LV) support has been suggested to improve infarct coronary flow, its specific mechanism remains to be clarified. LV support reduced LV pressure, and elevated coronary pressure during the late diastolic phase, resulting in high coronary driving pressure. This study demonstrated for the first time that mechanical LV support extends diastolic phase, leading to increased infarct coronary flow. Future studies should evaluate the correlation between improved infarct coronary flow and resulting infarct size.

Abstract
Hypertension is a leading risk factor for cardiovascular disease in South Asia. The authors aimed to assess the cross-country differences in 24-h ambulatory, daytime, and nighttime systolic blood pressure (SBP) among rural population with uncontrolled clinic hypertension in Bangladesh, Pakistan, and Sri Lanka. The authors studied patients with uncontrolled clinic hypertension (clinic BP ≥ 140/90 mmHg) who underwent ambulatory blood pressure monitoring (ABPM) during the baseline assessment as part of a community-based trial. The authors compared the distribution of ABPM profiles of patients across the three countries, specifically evaluating ambulatory SBP levels with multivariable models that adjusted for patient characteristics. Among the 382 patients (mean age, 58.3 years; 64.7% women), 56.5% exhibited ambulatory hypertension (24-h ambulatory BP ≥ 130/80 mmHg), with wide variation across countries: 72.6% (Bangladesh), 50.0% (Pakistan), and 51.0% (Sri Lanka; P < .05). Compared to Sri Lanka, adjusted mean 24-h ambulatory, daytime, and nighttime SBP were higher by 12.24 mmHg (95% CI 4.28-20.20), 11.96 mmHg (3.87-20.06), and 12.76 mmHg (4.51-21.01) in Bangladesh, separately. However, no significant differences were observed between Pakistan and Sri Lanka (P > .05). Additionally, clinic SBP was significantly associated with 24-h ambulatory (mean 0.38, 95% CI 0.28-0.47), daytime (0.37, 0.27-0.47), and nighttime SBP (0.40, 0.29-0.50) per 1 mmHg increase. The authors observed substantial cross-country differences in the distribution of ABPM profiles among patients with uncontrolled clinic hypertension in rural South Asia. The authors findings indicated the need to incorporate 24-h BP monitoring to mitigate cardiovascular risk, particularly in Bangladesh.

Abstract
BACKGROUND Evidence suggests that exposure to per- and polyfluoroalkyl substances (PFAS) increases risk of high blood pressure (BP) during pregnancy. Prior studies did not examine associations with BP trajectory parameters (i.e., overall magnitude and velocity) during pregnancy, which is linked to adverse pregnancy outcomes. OBJECTIVES To estimate associations of multiple plasma PFAS in early pregnancy with BP trajectory parameters across the second and third trimesters. To assess potential effect modification by maternal age and parity. METHODS In 1297 individuals, we quantified six PFAS in plasma collected during early pregnancy (median gestational age: 9.4 weeks). We abstracted from medical records systolic BP (SBP) and diastolic BP (DBP) measurements, recorded from 12 weeks gestation until delivery. BP trajectory parameters were estimated via Super Imposition by Translation and Rotation modeling. Subsequently, Bayesian Kernel Machine Regression (BKMR) was employed to estimate individual and joint associations of PFAS concentrations with trajectory parameters - adjusting for maternal age, race/ethnicity, pre-pregnancy body mass index, income, parity, smoking status, and seafood intake. We evaluated effect modification by age at enrollment and parity. RESULTS We collected a median of 13 BP measurements per participant. In BKMR, higher concentration of perfluorooctane sulfonate (PFOS) was independently associated with higher magnitude of overall SBP and DBP trajectories (i.e., upward shift of trajectories) and faster SBP trajectory velocity, holding all other PFAS at their medians. In stratified BKMR analyses, participants with ≥ 1 live birth had more pronounced positive associations between PFOS and SBP velocity, DBP magnitude, and DBP velocity - compared to nulliparous participants. We did not observe significant associations between concentrations of the overall PFAS mixture and either magnitude or velocity of the BP trajectories. CONCLUSION Early pregnancy plasma PFOS concentrations were associated with altered BP trajectory in pregnancy, which may impact future cardiovascular health of the mother.

Abstract
Evidence on the long-term effects of reducing sedentary behaviour (SB) on blood pressure (BP) is scarce. Therefore, we performed a sub-analysis of the BP effects of a six-month intervention that aimed at reducing SB by 1 h/day and replacing it with non-exercise activities. Sixty-four physically inactive and sedentary adults with metabolic syndrome (58% female, 58 [SD 7] years, BP 143/88 [16/9] mmHg, SB 10 [1] h/day) were randomised into intervention (INT, n = 33) and control (CON, n = 31) groups. Resting BP and BP at each stage during and after a graded maximal bicycle ergometer test were measured before and after the intervention. SB, standing, moderate-to-vigorous physical activity (MVPA), and light physical activity (LPA) were measured in six-second intervals at baseline and during the whole six-month intervention using hip-worn accelerometers. The analyses were adjusted for BP medication status. The intervention resulted in a 40 min/day reduction in SB and concomitant 20 min/day increase in MVPA. Resting systolic BP was lower in the CON group before and after the intervention. No group x time interactions were observed in resting BP or BP during exercise at submaximal or maximal intensities, or during recovery. The changes in LPA and MVPA were inversely correlated with the changes in BP during light-to-moderate intensity exercise. An intervention that resulted in a 40 min/day reduction in SB for six months was not sufficient at influencing BP at rest, during or after exercise in adults with metabolic syndrome. However, successfully increasing LPA or MVPA might lower BP during light-to-moderate-intensity activities.

Abstract
Sleep-disordered breathing (SDB) can be a sequela of stroke caused by vascular injury to vital respiratory centers, cerebral edema, and increased intracranial pressure of space-occupying lesions. Likewise, obstructive sleep apnea (OSA) contributes to increased stroke risk through local mechanisms such as impaired ischemic cerebrovascular response and systemic effects such as promoting atherosclerosis, hypercoagulability, cardiac arrhythmias, vascular-endothelial dysfunction, and metabolic syndrome. The impact of OSA on stroke outcomes has been established, yet it receives less attention in national guidelines on stroke management than hyperglycemia and blood pressure dysregulation. Furthermore, whether untreated OSA worsens stroke outcomes is not well-described in the literature. This scoping review provides an updated investigation of the correlation between OSA and stroke, including inter-relational pathophysiology. This review also highlights the importance of OSA treatment and its role in stroke outcomes. Knowledge of pathophysiology, the inter-relationship between these common disorders, and the impact of OSA therapy on outcomes affect the clinical management of patients with acute ischemic stroke. In addition, understanding the relationship between stroke outcomes and pre-existing OSA will allow clinicians to predict outcomes while treating acute stroke.

Abstract
We aim to summarize selected late-breaking science on hypertension management strategies and disease presented at the 2023 American Heart Association (AHA) conference. The trials discussed below encompass stricter goals of blood pressure management and were expanded into different population groups from different countries with varied socioeconomic backgrounds and settings, collectively advancing our understanding of hypertension treatment and its impact on public health. We summarized the china rural health care project (CRHCP), a four-year study involving over 34,000 participants in rural China, emphasizing the potential of stricter blood pressure goals in lowering the incidence of all-cause dementia and cognitive impairment. Next, we explore the US-based CARDIA-SSBP study, which highlights the impact of dietary sodium on systolic blood pressure in middle-aged individuals. Through a randomized-order cross-over design, the study provides compelling evidence supporting the effectiveness of sodium reduction as a non-pharmacological approach to blood pressure control. The UK-based POP-HT trial offers critical insights into postpartum women with a history of hypertensive pregnancy. The trial emphasizes the benefits of self-monitoring and physician-optimized antihypertensive titration, showcasing significant blood pressure reductions in the intervention group. Furthermore, the KARDIA-1 study introduces us to Zilebesiran, an innovative RNA interference drug. This phase 2 study highlights its potential for achieving sustained blood pressure reductions and its favorable safety profile, marking a significant step forward in hypertension treatment. Lastly, we expand the practical application of the previously conducted landmark SPRINT trial, which showed cardiovascular benefit with intensive SBP control to less than 120 mm Hg in high-risk non-diabetic patients with hypertension compared with routine BP control to <140 mm Hg. The ESPRIT trial and the IMPACTS trial build upon the SPRINT trial, demonstrating the effects of intensive blood pressure lowering in Asian hypertensive patients and in 36 health care clinics in medically underserved states in the US: Louisiana and Mississippi. The IMPACTS trial and the "Hypertension Treatment in Nigeria Program" demonstrate the effectiveness of implementing comprehensive blood pressure control strategies in real-world settings. These studies highlight the feasibility and scalability of such interventions, especially in low-resource environments, and their potential to significantly improve public health outcomes.
