Abstract
Diets rich in taurine can increase the production of taurine-conjugated bile acids, which are known to exert antihypertensive effects. Despite their benefits to the heart, kidney and arteries, their role in the central nervous system during the antihypertensive process remains unclear. Since hypothalamic paraventricular nucleus (PVN) plays a key role in blood pressure regulation, we aimed to investigate the function of bile acids in the PVN. The concentration of bile acids in the PVN of spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (WKY) fed with normal chow was measured using LC-MS/MS, which identified taurocholic acid (TCA) as the most down-regulated bile acid. To fully understand the mechanism of TCA's functions in the PVN, bi-lateral PVN micro-infusion of TCA was carried out. TCA treatment in the PVN led to a significant reduction in the blood pressure of SHRs, with decreased plasma levels of norepinephrine and improved morphology of cardiomyocytes. It also decreased the number of c-fos+ neurons, reduced the inflammatory response, and suppressed oxidative stress in the PVN of the SHRs. Most importantly, the TGR5 receptors in neurons and microglia were activated. PVN infusion of SBI-115, a TGR5 specific antagonist, was able to counteract with TCA in the blood pressure regulation of SHRs. In conclusion, TCA supplementation in the PVN of SHRs can activate TGR5 in neurons and microglia, reduce the inflammatory response and oxidative stress, suppress activated neurons, and attenuate hypertension.

Abstract
BACKGROUND Copper (Cu) is a component that performs a crucial role in the normal function and development of the human body. Nonetheless, it is still largely unclear how Cu consumption in the diet relates to the risk for all-cause and cardiovascular disease (CVD) mortality. METHODS Data from the National Health and Nutrition Examination Survey from 2001-2018 were used to conduct a prospective cohort study of individuals between the ages of 20 years and above. Regression coefficients and 95% confidence intervals for the link between dietary Cu consumption and all-cause and cardiovascular-related mortality were computed utilizing univariate and multivariate-adjusted Cox proportional hazards models. RESULTS A total of 197.9 million non-institutionalized American citizens were represented by the NHANES's 39,784 participants. The link between Cu in the diet and all-cause mortality was discovered to be non-linear in our restricted cubic spline regression models. When comparing the highest with the lowest quartile of Cu consumption in the diet, the weighted multivariate hazard ratios for all-cause mortality were 0.91 (0.83-0.99) for Q2, 0.88 (0.80-0.97) for Q3, and 0.86 (0.76-0.98) for Q4 (P for trend = 0.017). An identical trend was observed for cardiovascular mortality, but the association is not significant. CONCLUSION The most important discovery was that higher dietary Cu consumption was associated with a lower risk of all-cause mortality. This trend was also consistent with that of cardiovascular-related mortality, but the association is not significant.

Abstract
Importance Asymptomatic blood pressure (BP) elevations are common in hospitalized older adults, and widespread heterogeneity in the clinical management of elevated inpatient BPs exists. Objective To examine the association of intensive treatment of elevated inpatient BPs with in-hospital clinical outcomes of older adults hospitalized for noncardiac conditions. Design, Setting, and Participants This retrospective cohort study examined Veterans Health Administration data between October 1, 2015, and December 31, 2017, for patients aged 65 years or older hospitalized for noncardiovascular diagnoses and who experienced elevated BPs in the first 48 hours of hospitalization. Interventions Intensive BP treatment following the first 48 hours of hospitalization, defined as receipt of intravenous antihypertensives or oral classes not used prior to admission. Main Outcome and Measures The primary outcome was a composite of inpatient mortality, intensive care unit transfer, stroke, acute kidney injury, B-type natriuretic peptide elevation, and troponin elevation. Data were analyzed between October 1, 2021, and January 10, 2023, with propensity score overlap weighting used to adjust for confounding between those who did and did not receive early intensive treatment. Results Among 66 140 included patients (mean [SD] age, 74.4 [8.1] years; 97.5% male and 2.6% female; 17.4% Black, 1.7% Hispanic, and 75.9% White), 14 084 (21.3%) received intensive BP treatment in the first 48 hours of hospitalization. Patients who received early intensive treatment vs those who did not continued to receive a greater number of additional antihypertensives during the remainder of their hospitalization (mean additional doses, 6.1 [95% CI, 5.8-6.4] vs 1.6 [95% CI, 1.5-1.8], respectively). Intensive treatment was associated with a greater risk of the primary composite outcome (1220 [8.7%] vs 3570 [6.9%]; weighted odds ratio [OR], 1.28; 95% CI, 1.18-1.39), with the highest risk among patients receiving intravenous antihypertensives (weighted OR, 1.90; 95% CI, 1.65-2.19). Intensively treated patients were more likely to experience each component of the composite outcome except for stroke and mortality. Findings were consistent across subgroups stratified by age, frailty, preadmission BP, early hospitalization BP, and cardiovascular disease history. Conclusions and Relevance The study's findings indicate that among hospitalized older adults with elevated BPs, intensive pharmacologic antihypertensive treatment was associated with a greater risk of adverse events. These findings do not support the treatment of elevated inpatient BPs without evidence of end organ damage, and they highlight the need for randomized clinical trials of inpatient BP treatment targets.

Abstract
Resistant hypertension, defined as blood pressure that remains above goal despite using three or more antihypertensive medications, including a diuretic, affects a significant proportion of the hypertensive population and is associated with increased cardiovascular morbidity and mortality. Despite the availability of a wide range of pharmacological therapies, achieving optimal blood pressure control in patients with resistant hypertension remains a significant challenge. However, recent advances in the field have identified several promising treatment options, including spironolactone, mineralocorticoid receptor antagonists, and renal denervation. In addition, personalized management approaches based on genetic and other biomarkers may offer new opportunities to tailor therapy and improve outcomes. This review aims to provide an overview of the current state of knowledge regarding managing resistant hypertension, including the epidemiology, pathophysiology, and clinical implications of the condition, as well as the latest developments in therapeutic strategies and future prospects.

Abstract
The purpose of this study was to investigate the relationship between low energy availability (LEA) and nutritional content with high blood pressure (HBP) in African American Division I athletes. Twenty-three D1 African American pre-season athletes were recruited to participate. HBP was defined as >120 systolic blood pressure (BP) and <80 diastolic BP. Athletes self-reported nutritional intake using a non-consecutive 3-day food recall which was then reviewed by a sports dietitian. LEA was evaluated as total energy intake-total daily energy expenditure (TDEE), which was predicted. Additionally, micronutrients were evaluated. A statistical analysis relied on Spearman correlation (R), standardized mean difference with 95% confidence interval, mean ± SD, and odds ratios (OR). Correlation values were categorized: 0.20-0.39 = low; 0.40-0.69 = moderate; 0.70-1.0 = strong. A moderate relationship was observed between HBP and LEA (R = 0.56) with 14/23 having HBP. Of the 14 athletes observed with HBP, 78.5% (11/14) were calorically deficient (-529 ± 695 kcal) with an OR of 7.2. Micronutrient intake deficiencies were ubiquitous among the 23 HBP athletes: poly-unsaturated fatty acid -29.6%; omega-3 -26.0%; iron -46.0%; calcium -25.1%; and sodium -14.2%, amongst others. LEA and micronutrient deficiencies may contribute to HBP in Black D1 athletes, which has been shown to be the most common modifiable risk factor to decrease the risk of sudden cardiac death.

Abstract
BACKGROUND Living with a partner and separation is becoming more common among older people. Mortality disparities associated with marital status are significant in increasingly diverse aging populations. The link between marital status and all-cause mortality risk in older adults remains uncertain. METHODS This prospective cohort study included data from the US National Health and Nutrition Examination Survey (NHANES). We included NHANES participants ≥ 60 years of age (data from 1999 to 2014). Data for mortality follow-up beginning from the commencement date of survey participation to the last day of December 2015. Univariate- and multivariate-adjusted Cox proportional hazard models for marital status were estimated, and the findings were presented as regression coefficients and 95% confidence intervals (CI). Kaplan-Meier curves were reported. RESULTS Compared to never married individuals, the risk of all-cause mortality was 0.77 (0.50-1.18), 0.72 (0.56-0.93), 0.56 (0.36-0.88), and 0.84 (0.67-1.07) in those people living with a partner, married, separated, and divorced, respectively, after adjusting for demographics, socioeconomics, behavior, anthropometric variables, and medical history. The risk of all-cause mortality was 1.24 (0.97-1.59) in widowed participants. CONCLUSION This population-based cohort study included a large sample size followed by long-term follow-up. The association between marriage, health, and reduced mortality in older individuals has been illustrated in this study. Being married or separated was associated with a lower risk of mortality.

Abstract
Arterial hypertension, particularly elevated systolic blood pressure, is the most common risk factor for cardio- and cerebrovascular morbidity and mortality in women as it is in men. Blood pressure regulation and the development of sustained hypertension differ by sex. There are still few data on the question of whether the current normal values can apply equally to men and women and on the question of a different effect and dosage of antihypertensive drugs in women.

Abstract
OBJECTIVES The formation of vulnerable carotid artery plaque may be closely related to a single factor or caused by multiple factors. This paper discusses the pathogenic risk factors for vulnerable plaque in patients with severe internal carotid artery (ICA) stenosis who received endarterectomy through regression analysis. MATERIALS AND METHODS A total of 98 patients with a complete clinical and laboratory assessment underwent carotid endarterectomy. Metabolic syndrome (MetS) and MetS components, ICA plaque thickness and ICA peak systolic velocity, previous ischemic stroke or transient ischemic attack (TIA), and other risk factors were included in the pathogenic risk factor for vulnerable plaque. Univariate logistic regression analysis was used to determine vulnerable carotid plaque risk factors. If P <0.2, it was considered potential confounders. Binary logistic regression model was controlled for potential confounders. RESULTS Among the 98 patients, stable carotid plaques 38 (39%) and unstable carotid plaques 60 (61%), male 76 (77.6%) and female 22 (22.4%), and Han Chinese 68 (68.4%) and Mongols 30 (30.6%). Univariate logistic regression to P <0.2 has 6 risk factors, which are previous ischemic stroke or TIA, ICA peak systolic velocity, ICA plaque thickness, body mass index, total cholesterol, and alcohol consumption. The significant result of the binary logistic regression analysis was the previous ischemic stroke or TIA (OR=4.52; 95% CI, 1.67-12.09), P =0.003 and ICA peak systolic velocity (OR=1.01; 95% CI, 1.00-1.02), P =0.014. CONCLUSIONS The patients with previous ischemic stroke or TIA and higher ICA peak systolic velocity are associated with vulnerable plaque pathogenic features. There is no obligatory association between MetS and formation of carotid plaque vulnerability.

Abstract
Alcoholic beverages are common components of diets worldwide and understanding their effects on humans' health is crucial. Because hypertension is the leading risk factor for cardiovascular diseases and all-cause mortality, the relationship of alcohol consumption with blood pressure (BP) has been the subject of extensive investigation. For the purpose of this review, we searched the terms "alcohol", "ethanol", and "arterial hypertension" on Pubmed MeSH and selected the most relevant studies. Short-term studies showed a biphasic BP response after ingestion of high doses of alcohol, and sustained alcohol consumption above 30 g/day, significantly, and dose-dependently, increased the risk for hypertension. These untoward effects of alcoholic beverages on BP can be mediated by a multiplicity of neurohormonal mechanisms. In addition to the effects on BP, excess alcohol intake might contribute to cardiac and renal hypertensive organ damage, although some studies suggest possible benefits of moderate alcohol consumption on additional cardiovascular risk factors, such as diabetes and lipoprotein(a). Some intervention studies and cumulative analyses support the evidence of a benefit of the reduction/withdrawal of alcohol consumption on BP and cardiovascular outcomes. This is why guidelines of scientific societies recommend avoidance or limitation of alcohol intake below one unit/day for women and two units/day for men. This narrative article overviews all these topics, providing an update of the current knowledge on the relationship between alcohol and BP.

Abstract
Acromegaly is characterized by hypersecretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1), accompanied by a compromise in the perception of wellness. The Patient-Assessed Acromegaly Symptom Questionnaire (PASQ) is relevant to assessing signs and symptoms but is mainly used to evaluate the efficacy of a pharmacological intervention. To explore the perioperative variation in symptom severity, the divergence between subgroups stratified according to clinical outcomes or treatment modalities, and the interaction between symptom scores and clinical indices, we prospectively recruited 106 patients with acromegaly from 2016 to 2018. Oral glucose tolerance and GH tests were performed, and PASQ was administered before treatment and 6 months postoperatively. Patients were divided into active (n = 49) and remission (n = 57) groups according to postoperative GH and IGF-1 levels. PASQ scores and GH and IGF-1 levels decreased significantly postoperatively in both groups. A significantly higher preoperative headache score and greater extent of decrease in arthralgia were seen in the active and remission groups, respectively. No significant variation in PASQ scores was found between patients receiving surgery alone and those receiving preoperative somatostatin analogs. Preoperative fasting GH (GH0) levels were positively correlated with preoperative excessive perspiration. Further regression analyses validated the variation in GH0 as a noteworthy determinant of the extent of change in soft-tissue swelling, excessive perspiration, fatigue, and total PASQ scores. Patient-reported symptoms were substantially alleviated after surgery, independent of endocrine remission or use of preoperative somatostatin. A GH level decrease was a notable coefficient for PASQ scores.

Abstract
Hypertension is the modifiable risk factor causing the largest loss in healthy life-years. The risk of cardiovascular events increases exponentially with the level of blood pressure (BP), starting from 115mmHg for systolic BP. Out-of-office BP measurements (self-measurements or ambulatory BP measurements) are now preferred for the diagnosis and follow up. In the absence of a preferred indication, antihypertensive treatment is based on thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers. These treatments are associated with a significant reduction in morbidity and mortality in people with office BP ≥ 140/90mmHg (self-measurements ≥ 135/85mmHg). For people at high cardiovascular risk, especially those with a history of cardiovascular disease, starting the treatment for an office BP ≥ 130/80mmHg is also beneficial (self-measurements ≥ 130/80mmHg as well). It is now common to start treatment with half-dose dual therapy, which is more effective and better tolerated than full-dose monotherapy. The clinical effect is assessed at 4 weeks and intensification, if required, is then usually done by switching to the same dual therapy at full-dose for both components.

Abstract
Patients with masked hypertension (MH) and masked uncontrolled hypertension (MUCH) are easily overlooked, and both cause target organ damage. We propose a prediction model for MH and MUCH patients based on clinical features at a single outpatient visit. Data collection was planned before the index test and reference standard were after. Thus, we retrospectively collect analyzed 804 subjects who underwent ambulatory blood pressure monitoring (ABPM) at Renmin Hospital of Wuhan University. These patients were divided into normotension/controlled hypertension group (n = 121), MH/MUCH (n = 347), and sustained hypertension (SH)/sustained uncontrolled hypertension group (SUCH) (n = 302) for baseline characteristic analysis. Models were constructed by logistic regression, a nomogram was visualized, and internal validation by bootstrapping. All groups were performed according to the definition proposed by the Chinese Hypertension Association. Compared with normotension/controlled hypertension, patients with MH/MUCH had higher office blood pressure (BP) and were more likely to have poor liver and kidney function, metabolic disorder and myocardial damage. By analysis, [office systolic blood pressure (OSBP)] (P = .004) and [office diastolic blood pressure (ODBP)] (P = .007) were independent predictors of MH and MUCH. By logistic regression backward stepping method, office BP, body mass index (BMI), total cholesterol (Tch), high-density lipoprotein cholesterol (HDL-C), and left ventricular mass index are contained in this model [area under curve (AUC) = 0.755] and its mean absolute error is 0.015. Therefore, the prediction model established by the clinical characteristics or relevant data obtained from a single outpatient clinic can accurately predict MH and MUCH.

Wang L, Yi Z. Association of the Composite dietary antioxidant index with all-cause and cardiovascular mortality: A prospective cohort study. Front Cardiovasc Med 2022; 9:993930. [PMID: 36267633 PMCID: PMC9577254 DOI: 10.3389/fcvm.2022.993930] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 09/16/2022] [Indexed: 12/05/2022] Open
Abstract
Background According to epidemiological and experimental data, high individual dietary antioxidant intake is correlated with reduced cancer risk. The correlations between combined dietary antioxidants and the risk of all-cause and cardiovascular mortality remain unclear. Consequently, this study focused on evaluating the correlation between the food-derived Composite Dietary Antioxidant Index (CDAI) and all-cause and cardiovascular mortality. Materials and methods Two years of data collected from participants aged ≥20 years were included in this prospective cohort study, which was obtained from the US National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. The US NHANES adopted a complicated, multistage probability sampling method to collect health data representing the US population. Data collection was done through in-person interviews, virtual physical examinations, and laboratory tests. Mortality-related follow-up statistics from the start of the survey to 31 December 2019 were available. The shape of the correlation between CDAI and all-cause and cardiovascular mortality was inspected using a restricted cubic spline model. For CDAI and all-cause and cardiovascular mortality, the univariate- and multivariate-adjusted Cox proportional hazard models were estimated and presented as regression coefficients and 95% confidence intervals. Results In total, 44,031 NHANES participants represented 339.4 million non-institutionalized residents of the US (age, 47.2 ± 16.9 years; 52.5% women, 70.2% non-Hispanic whites, 10.8% non-Hispanic black people, and 7.5% Mexican Americans). In the 118-month follow-up, 9,249 deaths were reported, including 2,406 deaths resulting from heart disease and 519 deaths due to cerebrovascular disease. In the restricted cubic spline regression models, a linear relationship between CDAI and all-cause mortality was present. The weighted multivariate hazard ratios for all-cause mortality were computed to be 0.97 (0.87–1.07) for Q2, 0.88 (0.81–0.96) for Q3, and 0.90 (0.80–1.00) for Q4 (P for trend = 0.009) upon comparison with the lowest quartile of CDAI, and an identical trend was observed for cardiovascular mortality. Conclusion A high CDAI was linked to decreased all-cause and cardiovascular mortality risk. The intake of an antioxidant-rich diet significantly prevents cardiovascular mortality. To shed more light on these outcomes, more itemized investigations such as randomized control trials are required.

Impact of Modified H<sub>2</sub>FPEF Score on Chronic Limb-Threatening Ischemia in Patients With Lower Extremity Artery Disease Who Underwent Endovascular Therapy. Circ Rep 2022; 4:378-387.

Abstract
Background: Lower extremity artery disease (LEAD) is an arterial occlusive disease characterized by an insufficient blood supply to the lower limb arteries. The H2FPEF score, comprising Heavy, Hypertensive, atrial Fibrillation, Pulmonary hypertension, Elder, and Filling pressure, has been developed to identify patients at high risk of heart failure (HF) with preserved ejection fraction. This study assessed the impact of modified H2FPEF scores on chronic limb-threatening ischemia (CLTI) in patients with LEAD. Methods and Results: This study was a prospective observational study. Because the definition of obesity differs by race, we calculated the modified H2FPEF score using a body mass index >25 kg/m2
to define obesity in 293 patients with LEAD who underwent first endovascular therapy. The primary endpoints were newly developed and recurrent CLTI. The secondary endpoint was a composite of events, including mortality and rehospitalization due to worsening HF and/or CLTI. The modified H2FPEF score increased significantly with advancing Fontaine classes. Multivariate Cox proportional hazard analysis revealed that the modified H2FPEF score was an independent predictor of newly developed and recurrent CLTI and composite events. The net reclassification index and integrated discrimination improvement were significantly improved by adding the modified H2FPEF score to the basic predictors. Conclusions: The modified H2FPEF score was associated with LEAD severity and future CLTI development, suggesting that it could be a feasible marker for patients with LEAD.

Abstract
It has long been recognized that there are significant differences between the sexes affecting prevalence, incidence, and severity over a broad range of diseases. Until the early 1990s, the limited research conducted on women's health focused primarily on diseases affecting fertility and reproduction, and women were excluded from most clinical trials. For these reasons, the prevention, diagnosis, and treatment of serious chronic diseases such as cardiovascular disease in women continue to be based primarily on findings in men, and sex-specific clinical guidelines are mostly lacking. Hypertension, obesity, and diabetes, interrelated risk factors for cardiovascular disease, differ by sex in terms of prevalence and adverse effects as well as by genetics and biology. Research is needed to understand sex differences in hypertension, obesity, and diabetes to optimally inform sex-specific prevention, diagnosis, and treatment strategies for women and men. In this way, sex-specific clinical guidelines can be developed where warranted.

Diuretics versus others for long-term clinical outcomes as first-line antihypertensive medications: analysis of national real-world database. Hypertens Res 2022; 45:758-768.

Abstract
Although several large trials that included African American patients with hypertension have demonstrated the superiority of diuretics as an initial monotherapy, its applicability to other ethnicities remains questionable. The purpose of this study was to investigate whether diuretics as first-line antihypertensive medications are superior to other classes of drugs in the Korean population. Using the Korean National Health Insurance Service database, we analyzed 95,201 Korean hypertensive patients without prior history of cardiovascular disease who started a single antihypertensive drug between January 2002 and December 2017. The primary endpoint was a composite of cardiovascular death, myocardial infarction and stroke. Each endpoint was compared among five classes of antihypertensive drugs [diuretics, angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), and beta-blockers (BBs)]. In multivariable Cox analysis, diuretics were superior to ACEIs (hazard ratio [HR], 1.58-2.01), inferior to ARBs (HR, 0.37-0.43) and similar to CCBs and BBs for the primary endpoint. Similar findings were obtained for all-cause and cardiovascular mortality and stroke. This result was consistently observed in the longer treatment group and in the propensity score-matched pairs. In Korean hypertensive patients without cardiovascular disease, initiation with diuretics could not be superior to other medications, but rather inferior to ARBs in preventing adverse cardiovascular outcomes. Randomized studies are needed to confirm our results.

Abstract
BACKGROUND The primary objective of this analysis is to assess if greater exposure to any major antihypertensive drug class was associated with reduced primary composite outcome events in SPRINT (Systolic Blood Pressure Intervention Trial). METHODS This is a secondary analysis of the SPRINT trial evaluating whether longitudinal, time varying exposure to any major antihypertensive drug class had any impact on primary outcome events, after adjusting for effects of randomization arm, time varying achieved systolic blood pressure, other drug class exposure, and baseline characteristics. RESULTS Nine thousand two hundred fifty-two participants were included. After adjustments, exposure of one year or greater to thiazide-type diuretics or renin-angiotensin system blockers was associated with significantly fewer primary events than exposure of less than one year (hazard ratio, 0.78 [95% CI, 0.64-0.94]). There was no significant difference with longer versus shorter exposure to calcium channel blockers. Greater exposure to beta-blockers was associated with an increase in primary events compared with exposure of <1 year (hazard ratio, 1.35 [95% CI, 1.13-1.62]). Furthermore, thiazide-type diuretics were associated with a reduction in heart failure events and renin-angiotensin system blockers with reduced myocardial infarction. Both were associated with less cardiovascular deaths. CONCLUSIONS The SPRINT trial demonstrated a lower target blood pressure led to reductions in adverse cardiovascular events. This analysis suggests greater exposure to thiazide-type diuretics and renin-angiotensin system blockers also contributed to reduced adverse cardiovascular events. Greater exposure to beta-blockers was associated with increased cardiovascular events.

Abstract
Aims The impact of blood pressure (BP) levels on subclinical left ventricular (LV) dysfunction and possible sex‐specific difference remains unclarified. This study investigated the relationship between BP categories given in the new 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline and subclinical LV dysfunction in subjects free of cardiac disease. Methods and results We examined antihypertensive medication‐naive 858 individuals who underwent extensive cardiovascular health check‐up. LV global longitudinal (LVGLS) and circumferential strain (LVGCS) were assessed by two‐dimensional speckle‐tracking echocardiography. Participants were categorized into four groups: normal BP, elevated BP, isolated diastolic hypertension (IDH), and systolic hypertension (SH). Among the 858 participants, 422 individuals had normal BP, 113 had elevated BP, 160 had IDH, and 163 had SH. Prevalence of abnormal LVGLS (>−18.6%) was greatest in SH (19.0%), followed by IDH (17.5%), elevated BP (14.2%), and normal BP (7.1%, P < 0.001); no significant differences were observed for LVGCS (P = 0.671). In the multivariable analyses, IDH and SH were associated with impaired LVGLS [adjusted odds ratio (OR) 2.69 and 2.66, P < 0.001], and borderline significance was observed for elevated BP (adjusted OR 1.90, P = 0.060); there was no significant association between any of the BP groups and LVGCS. In sex‐stratified analysis, IDH and SH carried the significant risk of abnormal LVGLS in both sexes, while elevated BP was associated with LVGLS only in women. Conclusions Isolated diastolic hypertension and SH redefined by ACC/AHA guideline carried significant risk for LVGLS, but not LVGCS. Elevated BP was associated with LVGLS only in women. Our findings provide information on cardiac correlates of the newly established BP categories.

Abstract
Prior study has demonstrated that gut microbiota at the genus level is significantly altered in patients with growth hormone (GH)-secreting pituitary adenoma (GHPA). Yet, no studies exist describing the state of gut microbiota at species level in GHPA. We performed a study using 16S rRNA amplicon sequencing in a cohort of patients with GH-secreting pituitary adenoma (GHPA, n = 28) and healthy controls (n = 67). Among them, 9 patients and 10 healthy controls were randomly chosen and enrolled in metagenomics shotgun sequencing, generating 280,426,512 reads after aligning to NCBI GenBank DataBase to acquire taxa information at the species level. Weighted UniFrac analysis revealed that microbial diversity was notably decreased in patients with GHPA, consistent with a previous study. With 16S rRNA sequencing, after correction for false-discovery rate (FDR), rank-sum test at the genus level revealed that the relative abundance of Oscillibacter and Enterobacter was remarkably increased in patients and Blautia and Romboutsia genera predominated in the controls, augmented by additional LEfSe (linear discriminant analysis effect size) analysis. As for further comparison at the species level with metagenomics sequencing, rank-sum test together with LEfSe analysis confirmed the enrichment of Alistipes shahii and Odoribacter splanchnicus in the patient group. Notably, LEfSe analysis with metagenomics also demonstrated that Enterobacter sp. DC1 and Enterobacter sp. 940 PEND, derived from Enterobacter, were both significantly enriched in patients. Functional analysis showed that amino acid metabolism pathway was remarkably enriched in GHPA, while carbohydrate metabolism pathway was notably enriched in controls. Further, significant positive correlations were observed between Enterobacter and baseline insulin-like growth factor 1 (IGF-1), indicating that Enterobacter may be strongly associated with GH/IGF-1 axis in GHPA. Our data extend our insight into the GHPA microbiome, which may shed further light on GHPA pathogenesis and facilitate the exploration of novel therapeutic targets based on microbiota manipulation. IMPORTANCE Dysbiosis of gut microbiota is associated not only with intestinal disorders but also with numerous extraintestinal diseases. Growth hormone-secreting pituitary adenoma (GHPA) is an insidious disease with persistent hypersecretion of GH and IGF-1, causing increased morbidity and mortality. Researches have reported that the GH/IGF-1 axis exerts its own influence on the intestinal microflora. Here, the results showed that compared with healthy controls, GHPA patients not only decreased the alpha diversity of the intestinal flora but also significantly changed their beta diversity. Further, metagenomics shotgun sequencing in the present study exhibited that Enterobacter sp. DC1 and Enterobacter sp. 940 PEND were enriched in patients. Also, we were pleasantly surprised to find that the Enterobacter genus was strongly positively correlated with baseline IGF-1 levels. Collectively, our work provides the first glimpse of the dysbiosis of the gut microbiota at species level, providing a better understanding of the pathophysiological process of GHPA.

Abstract
SUMMARY By analyzing data from NHANES, we aimed to evaluate the prevalence, characteristics, and associated factors of wrist fractures in Americans aged 50 and above. INTRODUCTION Wrist fractures, whose prevalence increases with age, are one of the most common fractures in the United States. However, epidemiological studies on the prevalence of wrist fractures of certain ages were limited. METHODS The data of Americans aged 50 or above from 2013-2014 and 2017-2018 in NHANES were extracted and analyzed. RESULTS The prevalence of wrist fractures among Americans whose age was 50 or above was 12%, which was similar between men and women (men 12.8% vs. women 11.4%, p = 0.267). Among those who had experienced their first wrist fracture, 17.8% of the population experienced a second wrist fracture. The top two causes of the first wrist fracture were a fall from a standing height (56%) or a hard fall (34.8%). The prevalence of wrist fractures was higher in men than in women (13.7% versus 8.7%, p = 0.023) aged < 60, but higher in women than in men aged ≥ 60 (11.8% versus 14.3%, p = 0.007). Multivariate analysis showed that obesity, frequent drinking, current smoking, high serum phosphate level, non-Hispanic white women, and osteoporosis were independently associated with wrist fractures. Stratified by race, osteoporosis, frequent drinking, and high serum phosphate level were risk factors for wrist fractures in all races. As for Mexican Americans, non-Hispanic whites, and other races including multi-racial, current smoking was a risk factor of wrist factures. Furthermore, obesity was positively associated with wrist fractures in Mexican Americans, other Hispanics, and non-Hispanic whites. CONCLUSION The prevalence of wrist fractures in Americans aged 50 and above was 12%. Falling from a standing height was the main cause of the first wrist fracture. Frequent drinking, current smoker, high serum phosphate level, osteoporosis, obesity, and non-Hispanic women were more likely to experience wrist fractures.

Abstract
BACKGROUND The 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline recommends using 10-year predicted atherosclerotic cardiovascular disease (ASCVD) risk to guide decisions to initiate antihypertensive medication. METHODS We included adults aged 40-79 years from the National Health and Nutrition Examination Survey 2013-2018 (n = 8803). We computed 10-year predicted ASCVD risk using the Pooled Cohort risk equations. Clinical CVD was self-reported. Analyses were conducted overall and among those with stage 1 hypertension, defined by a mean SBP of 130-139 mmHg or DBP of 80-89 mmHg. In subgroups defined by diabetes, chronic kidney disease (CKD), and age at least 65 years, we estimated the proportion of United States adults with high ASCVD risk (i.e. 10-year predicted ASCVD risk ≥10% or clinical CVD) and estimated age-adjusted probability of having high ASCVD risk. RESULTS Among United States adults, an estimated 72.3, 64.5, and 83.9 of those with diabetes, CKD, and age at least 65 years had high ASCVD risk, respectively. Among United States adults with stage 1 hypertension, an estimated 55, 36.7, and 72.6% of those with diabetes, CKD, and age at least 65 years had high ASCVD risk, respectively. The probability of having high ASCVD risk increased with age and exceeded 50% for United States adults with diabetes and CKD at ages 52 and 57 years, respectively. For those with stage 1 hypertension, these ages were 55 and 64 years, respectively. CONCLUSION Most United States adults with diabetes, CKD, or age at least 65 years had high ASCVD risk. However, many with stage 1 hypertension did not.

Abstract
BACKGROUND The relationship between body mass index (BMI) and mortality in older adults diminished. It is necessary to examine other factors that may accurately predict mortality in older adults. The visceral adiposity index (VAI) is an uncomplicated marker specific to the gender that incorporates anthropometric data and lipid profiles. VAI has been proposed as a marker of visceral adipose tissue dysfunction and of the related cardiometabolic risk. The aim of this study was to evaluate the link of VAI with all-cause mortality among the elderly. METHODS The present prospective cohort study included data from 1999 to 2014 provided by the National Health and Nutrition Examination Survey (NHANES) in the United States. NHANES participants at or above the age of 65 were included. Data collection was carried out by taking face-to-face interviews, mobile-physical examinations, and lab tests. From the start of the survey to the end of December 2015, mortality-related follow-up statistics are available. The shape of the link between VAI and all-cause mortality was investigated using a restricted cubic spline model. Univariate- and multivariate-adjusted Cox proportional hazard models were estimated for VAI, and the results were presented as regression coefficients and 95% confidence intervals (CI). RESULTS The 82,091 NHANES participants represented 442.2 million non-institutionalized residents of the United States. A total of 11,173 older individuals (representing 23.3 million; aged 73.4 ± 5.8 years; 56.3% women, 82.7% non-Hispanic Whites, 6.8% non-Hispanic Blacks, and 3.3% Mexican Americans) were included in the study. During the 80-month follow-up period, 4466 fatalities were reported, including 825 deaths from cancer, 867 from heart disease, and 211 from cerebrovascular disease. The restricted cubic spline model demonstrated a robust J-shaped link between VAI and all-cause mortality, revealing a significant decrease in risk within the lower range of VAI, which attained the lowest risk close to 1.7. With VAI greater than 1.7, the risk of mortality increased with the increase of VAI (P for non-linearity = 0.025). In the multivariate-adjusted model, the risk of all-cause mortality was 0.73 (0.56-0.97) and 1.05 (1.01-1.09) in participants with VAI less than 1.7 and VAI greater than or equal to 1.7, respectively. CONCLUSION This investigation is a population-based cohort study with high sample sizes and a long-term in older individuals follow-up that showed a J-shaped link between VAI levels and all-cause mortality. Understanding the independent roles of VAI in the relationship between BMI and mortality is crucial to understanding the obesity paradox phenomenon.

Sensory Afferent Renal Nerve Activated Gαi 2 Subunit Proteins Mediate the Natriuretic, Sympathoinhibitory and Normotensive Responses to Peripheral Sodium Challenges. Front Physiol 2021; 12:771167. [PMID: 34916958 PMCID: PMC8669768 DOI: 10.3389/fphys.2021.771167] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 11/09/2021] [Indexed: 11/15/2022] Open
Abstract
We have previously reported that brain Gαi2 subunit proteins are required to maintain sodium homeostasis and are endogenously upregulated in the hypothalamic paraventricular nucleus (PVN) in response to increased dietary salt intake to maintain a salt resistant phenotype in rats. However, the origin of the signal that drives the endogenous activation and up-regulation of PVN Gαi2 subunit protein signal transduction pathways is unknown. By central oligodeoxynucleotide (ODN) administration we show that the pressor responses to central acute administration and central infusion of sodium chloride occur independently of brain Gαi2 protein pathways. In response to an acute volume expansion, we demonstrate, via the use of selective afferent renal denervation (ADNX) and anteroventral third ventricle (AV3V) lesions, that the sensory afferent renal nerves, but not the sodium sensitive AV3V region, are mechanistically involved in Gαi2 protein mediated natriuresis to an acute volume expansion [peak natriuresis (μeq/min) sham AV3V: 43 ± 4 vs. AV3V 45 ± 4 vs. AV3V + Gαi2 ODN 25 ± 4, p < 0.05; sham ADNX: 43 ± 4 vs. ADNX 23 ± 6, AV3V + Gαi2 ODN 25 ± 3, p < 0.05]. Furthermore, in response to chronically elevated dietary sodium intake, endogenous up-regulation of PVN specific Gαi2 proteins does not involve the AV3V region and is mediated by the sensory afferent renal nerves to counter the development of the salt sensitivity of blood pressure (MAP [mmHg] 4% NaCl; Sham ADNX 124 ± 4 vs. ADNX 145 ± 4, p < 0.05; Sham AV3V 125 ± 4 vs. AV3V 121 ± 5). Additionally, the development of the salt sensitivity of blood pressure following central ODN-mediated Gαi2 protein down-regulation occurs independently of the actions of the brain angiotensin II type 1 receptor. Collectively, our data suggest that in response to alterations in whole body sodium the peripheral sensory afferent renal nerves, but not the central AV3V sodium sensitive region, evoke the up-regulation and activation of PVN Gαi2 protein gated pathways to maintain a salt resistant phenotype. As such, both the sensory afferent renal nerves and PVN Gαi2 protein gated pathways, represent potential targets for the treatment of the salt sensitivity of blood pressure.

Abstract
Aims The existing instruments for assessing heart rate (HR) and heart rate variability (HRV) require contact area. This is difficult to obtain from specific groups of patients and from those moving. The aim of this study was to validate the use of the HRVCam software for measuring HR and HRV in healthy adults. Methods and results The HR and HRV variables were evaluated in terms of time and frequency using a webcam and Polar® S810i. The Shapiro-Wilk test was used to test the normality of the data, and the Pearson's correlation coefficient (r) was used to identify the possible correlation between the two instruments. The size of the effect was calculated based on a generalized linear model, and the Bland-Altman plots were used to analyse the agreement between the methods. The level of significance for all analyses was set at P < 0.05. We evaluated 102 participants, of whom 52% were men; 83.3% were aged between 18 and 29.9 years; and 84.3% were single. Conclusion There was a good agreement and moderate to strong correlations among all analysed variables. The biases were low, except for the low frequency/high frequency measures. Moreover, the difference between the samples was small to moderate. The results of this study corroborate the use of HRVCam for measuring HR and HRV.

Abstract
BACKGROUND Aortic diseases (ADs), including aortic dissection, aortic aneurysm, and aortic rupture, are fatal diseases with extremely high mortality rates. Hypertension has been reported to be associated with AD development; however, it remains unclear whether a 1-year change in diastolic blood pressure (DBP) is a risk factor for AD-related mortality in the general population.Methods and Results:This study used a nationwide database of 235,076 individuals (aged 50-75 years) who participated in the annual "Specific Health Check and Guidance in Japan" for 2 consecutive years between 2008 and 2010. There were 55 AD-related deaths during the follow-up period of 1,770 days. All subjects were divided into 4 groups based on the baseline DBP and change in DBP at 1 year: persistent high DBP, increasing DBP, decreasing DBP, and normal DBP. Kaplan-Meier analysis demonstrated that the persistent high DBP group had the greatest risk among the 4 groups. Multivariate Cox proportional hazard regression analysis demonstrated that both DBP and 1-year change in DBP were significantly associated with AD-related deaths. The prediction capacity was significantly improved by the addition of 1-year change in DBP to confounding risk factors. CONCLUSIONS This study demonstrated for the first time that a 1-year change in DBP was associated with AD-related deaths in the general population. Monitoring changes in DBP are of critical importance in the primary prevention of AD-related deaths in apparently healthy subjects aged 50-75 years.

Abstract
Our study supports the feasibility of measuring thrombogenicity in patients with acute myocardial infarction, with intent to predict periprocedural and long-term clinical events, in real-world clinical practice. Preprocedural assessment of ex vivo thrombogenicity (eg, platelet-fibrin clot strength by thromboelastography) was significantly associated with the risk of coronary microvascular dysfunction. A combined risk stratification with coronary microvascular dysfunction and platelet-fibrin clot strength increased the prognostic implication to predict the rates of long-term clinical outcomes.
The association between thrombogenicity and coronary microvascular dysfunction (CMD) has been poorly explored in patients with acute myocardial infarction (AMI). In our real-world clinical practice (N = 116), thrombogenicity was evaluated with thromboelastography and conventional hemostatic measures, and CMD was defined as index of microcirculatory resistance of >40 U using the invasive physiologic test. High platelet-fibrin clot strength (P-FCS) (≥68 mm) significantly increased the risk of postprocedural CMD (odds ratio: 4.35; 95% CI: 1.74-10.89). Patients with both CMD and high P-FCS had a higher rate of ischemic events compared to non-CMD subjects with low P-FCS (odds ratio: 5.58; 95% CI: 1.31-23.68). This study showed a close association between heightened thrombogenicity and CMD and their prognostic implications after reperfusion in acute myocardial infarction patients.

Abstract
OBJECTIVE The impact of nocturnal blood pressure (BP) on target organ damage (TOD) in chronic kidney disease (CKD) patients with normotension has not been established. In this study, we determined whether nocturnal BP is correlated with cardiovascular and renal damage independent of the 24-h BP in CKD patients with normotension or hypertension. METHODS A total of 1166 hospitalized patients with CKD not requiring dialysis were enrolled in this cross-sectional study, 421 and 745 of whom had normotension and hypertension, respectively. TOD was assessed by the left ventricular mass index (LVMI), estimated glomerular filtration rate (eGFR) and presence of proteinuria. Univariate and multivariable regression analyses were used to evaluate the relationships between nocturnal BP and TOD. RESULTS In the multivariable-adjusted models, including the 24-h BP, nocturnal SBP was independently associated with the LVMI, eGFR and proteinuria in patients with normotension (P < 0.05), while the nocturnal DBP was not correlated with proteinuria. The nocturnal SBP was associated with LVMI and proteinuria, but not the eGFR in patients with hypertension. We did not demonstrate an association between nocturnal DBP and TOD in these patients. When nocturnal SBP in patients with normotension was further divided into tertiles [tertile 1 (<104 mmHg), tertile 2 (104-114 mmHg) and tertile 3 (≥114 mmHg)], multivariate analysis showed that tertile 3 was independently associated with TOD. CONCLUSION Nocturnal SBP was shown to be an independent risk factor for TOD in patients with normotension. Targeting a nocturnal ambulatory SBP to less than 114 mmHg or even less than 104 mmHg may help prevent TOD in patients with CKD.

Abstract
One of the prominent reasons behind the deterioration of cardiovascular conditions is hypertension. Due to lack of specific symptoms, sometimes existing hypertension goes unnoticed until significant damage happens to the heart or any other body organ. Monitoring of BP at a higher frequency is necessary so that we can take early preventive measures to control and keep it within the normal range. The cuff-based method of measuring BP is inconvenient for frequent daily measurements. The cuffless BP measurement method proposed in this paper uses features extracted from the electrocardiogram (ECG) and photoplethysmography (PPG). ECG and PPG both have distinct characteristics, which change with the change of blood pressure levels. Feature extraction and hybrid feature selection algorithms are followed by a generalized penalty-based regression technique led to a new BP measurement process that uses the minimum number of features. The performance of the proposed technique to measure blood pressure was compared to an approach using an ordinary linear regression method with no feature selection and to other contemporary techniques. MIMIC-II database was used to train and test our proposed method. The root mean square error (RMSE) for systolic blood pressure (SBP) improved from 11.2 mmHg to 5.6 mmHg when the proposed technique was implemented and for diastolic blood pressure (DBP) improved from 12.7 mmHg to 6.69 mmHg. The mean absolute error (MAE) was found to be 4.91 mmHg for SBP and 5.77 mmHg for DBP, which have shown improvement over other existing cuffless techniques where the substantial number of patients, as well as feature selection algorithm, were implemented. In addition, according to the British Hypertension Society standard (BHS) standard for cuff-based BP measurement, the criteria for acceptable measurement are to achieve at least grade B; our proposed method also satisfies this criterion.

Abstract
Background A lower systolic blood pressure (SBP) target reduces major cardiovascular events and mortality from any cause of geriatric hypertension. However, the effect of different SBP targets on myocardial function remains unclear. This study aimed to determine changes in left ventricular (LV) strain in older hypertensive patients after 1 year of different SBP goals, and to evaluate its effects on myocardial mechanics in this population. Methods We studied 313 hypertensive adults aged 60 years or older after 1 year of the Systolic Blood Pressure Intervention Trial. They were divided into the intensive group (target SBP: 110–130 mmHg) and the standard group (target SBP: 130–150 mmHg). All participants underwent echocardiography within 1 week after enrollment and 1 year after participating in the study. Global longitudinal strain (GLS) of the LV (endocardial, middle, and epicardial layer: GLS-end, GLS-mid, and GLS-epi, respectively) and the improvement of GLS at 1 year (ΔGLS-end, ΔGLS-mid, and ΔGLS-epi) were measured. Results At 1 year, GLS-end in the intensive group was slightly improved compared with that before the trial (−23.78%±3.10% vs −22.58%±3.11%, P<0.05). The ΔGLS-end and ΔGLS-mid in the intensive group were higher than those in the standard group (1.20±0.23 vs 0.58±0.59% and 0.70±0.21 vs 0.52±0.17, P<0.05). Moreover, SBP at 1 year and an angiotensin II type 1 receptor antagonist were independent factors that affected ΔGLS-end (β= −0.005, P=0.004; β= 0.080, P<0.001, respectively). Conclusion These trial results suggest that a lower SBP target can slightly improve myocardial function in older hypertensive patients at 1 year.

[PMID: 34136539 PMCID: PMC8200397 DOI: 10.3389/fcvm.2021.644035] [Citation(s) in RCA: 57] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 04/22/2021] [Indexed: 12/11/2022] Open
Abstract
Background: Triglyceride-glucose (TyG) index is a recently proposed surrogate indicator of insulin resistance. Previous studies evaluating the association between TyG index and hypertension risk in general adult population showed inconsistent results. We performed a meta-analysis to systematically evaluate this association. Methods: Observational studies, which evaluated the independent association between TyG index and hypertension in the general adult population, were identified by systematic search of PubMed, Embase, Web of Science, Wanfang data, and Chinese National Knowledge Infrastructure databases. A random-effect model, which incorporated the potential intra-study heterogeneity, was used for the meta-analysis. Results: Eight observational studies including 200,044 participants were included. Results showed that compared with those with the lowest category of TyG index, subjects with the highest category of TyG index were associated with higher odds of hypertension [adjusted risk ratio (RR): 1.53, 95% confidence interval (CI): 1.26-1.85, I 2 = 54%, P < 0.001]. Sensitivity analysis by excluding one dataset at a time showed consistent result (adjusted RR: 1.44-1.62, P all < 0.001). Results of univariate meta-regression analysis showed that differences in sample size, mean age, male proportion, mean body mass index, and study quality score among the included studies did not have significant influence on the association between TyG index and hypertension (P values all > 0.10), suggesting that differences in these characteristics may not be the major source of heterogeneity. Subgroup analyses showed that study characteristics such as study design, participant ethnicity, age, or sex of the participants did not significantly affect the association (P for subgroup difference all >0.05). Conclusions: Higher TyG index may be associated with higher odds of hypertension in general adult population. Large-scale prospective cohort studies are needed to validate these findings, and further studies are needed to elucidate the potential pathophysiological mechanisms underlying the association between TyG index and hypertension.

Gender-Specific Prevalence of Risk Factors for Non-Communicable Diseases by Health Service Use among Schoolteachers in Afghanistan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115729. [PMID: 34073621 PMCID: PMC8198773 DOI: 10.3390/ijerph18115729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 05/18/2021] [Accepted: 05/19/2021] [Indexed: 12/04/2022]
Abstract
Objectives of this study were: (1) to examine gender differences in biomedical indicators, lifestyle behaviors, self-health check practices, receipt of professional non-communicable disease (NCD)-related lifestyle advice, and the use of health services among teachers in Afghanistan; and (2) to seek the patterns of these indicators among users and non-users of health services among both male and female teachers. This cross-sectional study was carried out among 600 schoolteachers in Kabul city in February 2017. Gender differences in percentage distributions of abnormal biomedical indicators, lifestyle behaviors, self-health check practices, and receipt of professional lifestyle advice were examined. These patterns were further analyzed according to the use of health services in the previous 12 months by both genders. The results showed that male teachers had a higher prevalence of hypertension, increased serum triglycerides, physically active lifestyle, and tobacco use than female teachers (28.2/20.4, p = 0.038; 47.0/37.9, p = 0.040; 54.3/40.9, p = 0.002; 15.8/0.7, p < 0.001, respectively); female teachers had a higher prevalence of increased serum LDL cholesterol, overweight/obesity, and frequent consumption of fruits/vegetables than male teachers (61.3/50.8, p = 0.018; 64.7/43.5, p < 0.001; 71.4/53.8, p < 0.001, respectively). Female teachers were more likely to receive professional lifestyle advice related to NCDs than male teachers. Although users of health services practiced self-health checks and received professional lifestyle advice more frequently than non-users, abnormal biomedical indicators were similarly shown among users and non-users of health services in both genders. In conclusion, high prevalence of abnormal biomedical indicators was indicated in both male and female teachers, although the specific abnormal biomedical indicators differed by gender. Users and non-users of health services presented a similar prevalence of these abnormal indicators. Understanding the differences in patterns of NCD risk factors is essential when developing gender-informed policies.

Abstract
BACKGROUND In high-income and low-income countries, including Ethiopia, hypertension (HTN) is a serious public health concern. As a consequence, a massive self-care practice (SCP) is necessary, and the domains of SCP, including adherence to medication, physical activity, weight management, low-salt diet, non-smoking, moderate alcohol usage, and dietary management, are required. However, there is no nationwide study on HTN SCPs in Ethiopia. This meta-analysis, therefore, aimed to estimate the pooled level of HCP among individuals living with HTN in Ethiopia. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was used to report this systematic review and meta-analysis. We systematically searched the databases PubMed/MEDLINE, Embase, Google Scholar and Science Direct for studies conducted in Ethiopia. All observational studies published until July 2020 were included. Data were analysed using R V.3.5.3 software, and the pooled prevalence with 95% CIs was presented using tables and forest plots. The presence of statistical heterogeneity (I 2) within the included studies was evaluated. We used a funnel plot to identify evidence of publication bias. The random-effects meta-analysis model was employed to estimate the pooled proportion of good HTN SCPs.This was submitted for registration with the International Prospective Register of Systematic Reviews in March 2020 and accepted with the registration number CRD42020175743 (https://www.crd.york.ac.uk/PROSPERO). RESULTS Our search databases produced 356 papers. Twelve of these papers fulfilled the inclusion and were found suitable for the review. The total population in this study was 3938. Off these hypertensive populations, 44% (95% CI 34 to 53) had good SCP. The subgroup analysis for each component of SCP was done. The subgroup analysis of good adherence to low-salt diet, alcohol abstinence, medication adherence, non-smoking, physical exercise and weight management was 52% (95% CI 39% to 66%), 77% (95% CI 69% to 88%), 65% (95% CI 45% to 85%), 92% (95% CI 88% to 95%), 43% (95% CI 30% to 56%) and 51% (95% CI 32% to 69%), respectively. In conclusion, nearly half of patients with HTN had good SCPs.

Abstract
BACKGROUND/PURPOSE Hypertension is a risk factor of incident diabetes. In 2017, the ACC/AHA updated the definition of hypertension to above 130/80 mmHg, while the 2018 ESC/ESH guideline and the JNC7 criteria remained the cutoff of 140/90 mmHg. This study was aimed to investigate how different cutoffs of hypertension affect the association of hypertension to incident diabetes and the progression of insulin resistance. METHODS A total of 1177 subjects without diabetes at baseline were followed for 4.5 years. Diabetes was diagnosed by the results of oral glucose tolerance tests and hemoglobin A1c, or if anti-diabetic agents were used. RESULTS Hypertension by both criteria was associated with incident diabetes. Change of HOMA2-IR every 5 years (ΔHOMA2-IR/5 yr) was higher in subjects with hypertension than those without (adjusted p = 0.044). Subjects with treated hypertension had the highest risk of diabetes (HR 2.98, p < 0.001) and ΔHOMA2-IR/5 yr, compared with subjects with normal blood pressure. However, the associations of hypertension, HR of incident diabetes and ΔHOMA2-IR/5 yr were attenuated by the 2017 ACC/AHA criteria, as compared with that by the JNC7 and 2018 ESC/ESH criteria. CONCLUSION Hypertension by both criteria is associated with incident diabetes and accelerated progression of insulin resistance, and the associations are attenuated by the 2017 ACC/AHA criteria.

Abstract
Cigarette smoking is among the most detrimental behaviors to cardiovascular health, resulting in arterial stiffening, endothelial dysfunction, and structural/functional alterations to the myocardium. Similar to cigarettes, cannabis is commonly smoked, and next to alcohol, is the most commonly used recreational substance in the world. Despite this, little is known about the long-term cardiovascular effects of smoking cannabis. This study explored the associations of cardiovascular structure and function with cannabis use in ostensibly healthy young participants (n = 35). Using echocardiography, carotid-femoral pulse wave velocity (cfPWV), and brachial flow-mediated dilation (FMD), we performed a cross-sectional assessment of cardiovascular function in cannabis users (n = 18) and controls (n = 17). There were no differences in cardiac morphology or traditional resting measures of systolic or diastolic function between cannabis users and controls (all P > 0.05), whereas cannabis users demonstrated reduced peak apical rotation compared with controls (cannabis users: 5.5 ± 3.8, controls: 9.6 ± 1.5; P = 0.02). Cannabis users had higher cfPWV compared with controls (cannabis users: 5.8 ± 0.6 m/s, controls: 5.3 ± 0.7 m/s; P = 0.05), whereas FMD was similar between cannabis users and controls (cannabis users: 8.3 ± 3.3%, controls: 6.8 ± 3.6%; P = 0.7). Young, healthy, and cannabis users demonstrate altered cardiac mechanics and greater aortic stiffness. Further studies should explore causal links between cannabis smoking and altered cardiovascular function.NEW & NOTEWORTHY Recreational cannabis is the most widely used substance in the world, other than alcohol. Yet, the effects of cannabis use on cardiovascular function and health are not well understood. Our cross-sectional data demonstrate that young, ostensibly healthy cannabis users have greater arterial stiffness and altered cardiac mechanics compared to nonusers. These findings suggest that cannabis users may be at greater risk of the development of future cardiovascular disease.

Risk of fatal and nonfatal coronary heart disease and stroke events among adult patients with hypertension: basic Markov model inputs for evaluating cost-effectiveness of hypertension treatment: systematic review of cohort studies. JOURNAL OF PHARMACEUTICAL HEALTH SERVICES RESEARCH 2021.

Abstract
Abstract
Objectives
Hypertension is a risk factor for a number of vascular and cardiac complications. A Markov like simulation based on cardiovascular disease (CVD) policy model is being used for evaluating cost-effectiveness of hypertension treatment. Stroke, angina, myocardial infarction (MI), cardiac arrest and all-cause mortality were only included CVD outcome variables in the model. Therefore this systematic review was conducted to evaluate completeness of CVD policy model for evaluation of cost-effectiveness across different regions.
Key findings
Fourteen cohort studies involving a total of 1 674 773 hypertensive adult population and 499 226 adults with treatment resistant hypertension were included in this systematic review. Hypertension is clearly associated with coronary heart disease (CHD) and stroke mortality, unstable angina, stable angina, MI, heart failure (HF), sudden cardiac death, transient ischemic attack, ischemic stroke, sub-arachnoid hemorrhage, intracranial hemorrhage, peripheral arterial disease (PAD), and abdominal aortic aneurism (AAA). Lifetime risk of developing HF is higher among hypertensives across all ages, with slight variation among regions. Treatment resistant hypertension is associated with higher relative risk of developing major CVD events and mortality when compared with the non-resistant hypertension.
Summary
The CVD policy model can be used in most of the regions for evaluation of cost-effectiveness of hypertension treatment. However, hypertension is highly associated with HF in Latin America, Eastern Europe, and Sub-Saharan Africa. Therefore, it is important to consider HF in CVD policy model for evaluating cost-effectiveness of hypertension treatment in these regions. We do not suggest the inclusion of PAD and AAA in CVD policy model for evaluating cost-effectiveness of hypertension treatment due to lack of sufficient evidence. Researchers should consider the effect of treatment resistant hypertension either through including in the basic model or during setting the model assumptions.

Abstract
Background and Purpose The present study aimed to compare the efficacy and tolerability of different blood pressure (BP)-lowering strategies.
Methods Randomized controlled trials that compared various antihypertensive treatments and stroke outcomes were included. Eligible trials were categorized into three scenarios: single or combination antihypertensive agents against placebos; single or combination agents against other agents; and different BP-lowering targets. The primary efficacy outcome was the risk reduction pertaining to strokes. The tolerability outcome was the withdrawal of drugs, owing to drug-related side effects (PROSPERO registration number CRD42018118454 [20/12/2018]).
Results The present study included 93 trials (average follow-up duration, 3.3 years). In the pairwise analysis, angiotensin-converting enzyme inhibitors (ACEis) and beta-blockers (BBs) were inferior to calcium channel blockers (CCBs) (odds ratio [OR], 1.123; 95% confidence interval [CI], 1.008 to 1.252) (OR, 1.261; 95% CI, 1.116 to 1.425) for stroke prevention, BB was inferior to angiotensin II receptor blockers (ARB) (OR, 1.361; 95% CI, 1.142 to 1.622), and diuretics were superior to ACEi (OR, 0.871; 95% CI, 0.771 to 0.984). The combination of ACEi+CCB was superior to ACEi+diuretic (OR, 0.892; 95% CI, 0.823 to 0.966). The network meta-analysis confirmed that diuretics were superior to BB (OR, 1.34; 95% CI, 1.11 to 1.58), ACEi+diuretic (OR, 1.47; 95% CI, 1.02 to 2.08), BB+CCB (OR, 2.05; 95% CI, 1.05 to 3.79), and renin inhibitors (OR, 1.87; 95% CI, 1.25 to 2.75) for stroke prevention. Regarding the tolerability profile, the pairwise analysis revealed that ACEi was inferior to CCB and less tolerable, compared to the other treatments.
Conclusions Monotherapy using diuretics, CCB, or ARB, and their combinations could be employed as first-line treatments for stroke prevention in terms of efficacy and tolerability.

Abstract
INTRODUCTION Angiotensin converting enzyme inhibitors (ACEIs) are widely prescribed medications. A recent British study reported a 14% increased risk of lung cancer with ACEI versus angiotensin receptor blocker (ARB) prescriptions, and risk increased with longer use. We sought to validate this observation. METHODS We searched the Intermountain Enterprise Data Warehouse from 1996 to 2018 for patients newly treated with an ACEI or an ARB and with ≥1 year's follow-up or to incident lung cancer or death. Unadjusted and adjusted hazard ratios (HRs) for lung cancer and for lung cancer or all-cause mortality were calculated for ACEIs compared to ARBs. RESULTS A total of 187,060 patients met entry criteria (age 60.2 ± 15.1 y; 51% women). During a mean of 7.1 years follow-up (max: 20.0 years), 3,039 lung cancers and 43,505 deaths occurred. Absolute lung cancer rates were 2.16 and 2.31 per 1000 patient-years in the ARB and ACEI groups, respectively. The HR of lung cancer was modestly increased with ACEIs (unadjusted HR = 1.11, CI: 1.02, 1.22, P = .014; adjusted HR = 1.18, CI: 1.06, 1.31, P = .002; number needed to harm [NNH] 6,667). Rates of the composite of lung cancer or death over time also favored ARBs. Lung cancer event curves separated gradually over longitudinal follow-up beginning at 10-12 years. CONCLUSIONS We noted a small long-term increase in lung cancer risk with ACEIs compared with ARBs. Separation of survival curves was delayed until 10-12 years after treatment initiation. Although the observed increases in lung cancer risk are small, implications are potentially important because of the broad use of ACEIs. Thus, additional work to validate these findings is needed.

Abstract
Cardiovascular disorders cause nearly one in three deaths in the United States. Short- and long-term care for these disorders is often determined in short-term settings. However, these decisions are made with minimal longitudinal and long-term data. To overcome this bias towards data from acute care settings, improved longitudinal monitoring for cardiovascular patients is needed. Longitudinal monitoring provides a more comprehensive picture of patient health, allowing for informed decision making. This work surveys sensing and machine learning in the field of remote health monitoring for cardiovascular disorders. We highlight three needs in the design of new smart health technologies: (1) need for sensing technologies that track longitudinal trends of the cardiovascular disorder despite infrequent, noisy, or missing data measurements; (2) need for new analytic techniques designed in a longitudinal, continual fashion to aid in the development of new risk prediction techniques and in tracking disease progression; and (3) need for personalized and interpretable machine learning techniques, allowing for advancements in clinical decision making. We highlight these needs based upon the current state of the art in smart health technologies and analytics. We then discuss opportunities in addressing these needs for development of smart health technologies for the field of cardiovascular disorders and care.

Abstract
OBJECTIVES To assess the effect of the 2017 American College of Cardiology and the American Heart Association (ACC/AHA) hypertension guideline on the prevalence of elevated blood pressure (BP) and hypertension and the initiation of antihypertensive treatment, as well as the level of adherence to the BP target in the Saudi population. DESIGN A cross-sectional study. PARTICIPANTS A total of 10 799 adults (≥18 years old), with three BP readings during 2017-2020 from the Saudi Biobank was used. PRIMARY OUTCOME Hypertension was defined using three sources: the Joint National Committee 7 Blood Pressure Guideline (JNC-7) guideline (systolic BP (SBP)≥140 or diastolic BP (DBP)≥90 mm Hg), the 2017 ACC/AHA guideline (SBP≥130 or DBP≥80 mm Hg) and a self-reported hypertension diagnosis. RESULTS The prevalence of hypertension, according to the JNC-7 guideline, was 14.49% (95% CI 14.37 to 14.61), and the 2017 ACC/AHA, 40.77% (95% CI 40.60 to 40.94), a difference of 26.28%. Antihypertensive medication was recommended for 24.84% (95% CI 24.69 to 24.98) based on the JNC-7 guideline and 27.67% (95% CI 27.52 to 27.82) using the 2017 ACC/AHA guideline. Lifestyle modification was recommended for 13.10% (95% CI 12.47 to 13.74) of patients with hypertension who were not eligible for a pharmacological intervention, based on the 2017 ACA/AHA guideline. For patients with prescribed antihypertensive medication, 49.56% (95% CI 45.50 to 53.64) and 27.81% (95% CI 24.31 to 31.59) presented with a BP reading above the treatment goal, based on the 2017 ACA/AHA and JNC-7 guidelines, respectively. Using the two definitions, the risk factors were older age, male gender, diabetes diagnosis, increased body mass index, waist circumference and waist-to-hip ratio. CONCLUSIONS According to the 2017 ACC/AHA guideline, the prevalence of hypertension has increased significantly, but there was only a small increase in the proportion of patients recommended for antihypertensive treatment. A large proportion of patients with prescribed antihypertensive medication, had a BP above the target. Unless public health prevention efforts are adopted, the increased prevalence of elevated BP and hypertension will increase cardiovascular disease.

Abstract
BACKGROUND Globally 71% of deaths are attributed to non-communicable diseases (NCD). The workplace is an opportune setting for health promotion programs and interventions that aim to prevent NCDs. However, much of the current evidence is from high-income countries. OBJECTIVE The aim of this study was to evaluate changes in NCD risk factors, associated with the Healthy Choices at Work programme (HCWP), at a commercial power plant in South Africa. METHODS This was a before-and-after study in a randomly selected sample of 156 employees at baseline and 137 employees at 2-years. The HCWP focused on food services, physical activity, health and wellness services and managerial support. Participants completed questionnaires on tobacco smoking, harmful alcohol use, fruit and vegetable intake, physical activity, psychosocial stress and history of NCDs. Clinical measures included blood pressure, total cholesterol, random blood glucose, body mass index, waist circumference and waist-to-hip ratio. The 10-year cardiovascular risk was calculated using a validated algorithm. Sample size calculations evaluated the power of the sample to detect meaningful changes in risk factors. RESULTS Paired data was obtained for 137 employees, the mean age was 42.7 years (SD 9.7) and 64% were male. The prevalence of sufficient fruit and vegetable intake increased from 27% to 64% (p < 0.001), those meeting physical activity guidelines increased from 44% to 65% (p < 0.001). Harmful alcohol use decreased from 21% to 5% (p = 0.001). There were clinical and statistically significant improvements in systolic and diastolic blood pressure (mean difference -10.2 mmHg (95%CI: -7.3 to -13.2); and -3.9 mmHg (95%CI: -1.8 to -5.8); p < 0.001) and total cholesterol (mean difference -0.45 mmol/l (-0.3 to -0.6)). There were no significant improvements in BMI. Psychosocial stress from relationships with colleagues, personal finances, and personal health improved significantly. The cardiovascular risk score decreased by 4.5% (> 0.05). CONCLUSION The HCWP was associated with clinically significant reductions in behavioural, metabolic and psychosocial risk factors for NCDs.

Abstract
Background Food insecurity (FIS) is an important public health issue associated with cardiovascular risk. Given the association of FIS with diets of poorer nutritional quality and higher salt intake as well as chronic stress, numerous studies have explored the link between FIS and hypertension. However, no systematic review or meta-analysis has yet to integrate or analyze the existing literature. Methods We performed a wide and inclusive search of peer-reviewed quantitative data exploring FIS and hypertension. A broad-terms, systematic search of the literature was conducted in PubMed, Embase, Scopus, and Web of Science for all English-language, human studies containing primary data on the relationship between FIS and hypertension. Patient population characteristics, study size, and method to explore hypertension were extracted from each study. Effect sizes including odds ratios and standardized mean differences were extracted or calculated based on studies’ primary data. Comparable studies were combined by the random effects model for meta-analyses along with assessment of heterogeneity and publication bias. Results A total of 36 studies were included in the final analyses. The studies were combined into different subgroups for meta-analyses as there were important differences in patient population characteristics, methodology to assess hypertension, and choice of effect size reporting (or calculability from primary data). For adults, there were no significantly increased odds of elevated blood pressures for food insecure individuals in studies where researchers measured the blood pressures: OR = 0.91 [95%CI: 0.79, 1.04; n = 29,781; Q(df = 6) = 7.6; I2 = 21%]. This remained true upon analysis of studies which adjusted for subject BMI. Similarly, in studies for which the standardized mean difference was calculable, there was no significant difference in measured blood pressures between food secure and FIS individuals: g = 0.00 [95%CI: -0.04, 0.05; n = 12,122; Q(df = 4) = 3.6; I2 = 0%]. As for retrospective studies that inspected medical records for diagnosis of hypertension, there were no significantly increased odds of hypertension in food insecure adults: OR = 1.11 [95%CI: 0.86, 1.42; n = 2,887; Q(df = 2) = 0.7; I2 = 0%]. In contrast, there was a significant association between food insecurity and self-reports of previous diagnoses of hypertension: 1.46 [95%CI: 1.13, 1.88; n = 127,467; Q(df = 7) = 235; I2 = 97%]. Only five pediatric studies were identified which together showed a significant association between FIS and hypertension: OR = 1.44 [95%CI: 1.16, 1.79; n = 19,038; Q(df = 4) = 5.7; I2 = 30%]. However, the small number of pediatric studies were not sufficient for subgroup meta-analyses based on individual study methodologies. Discussion In this systematic review and meta-analysis, an association was found between adult FIS and self-reported hypertension, but not with hypertension determined by blood pressure measurement or chart review. Further, while there is evidence of an association between FIS and hypertension among pediatric subjects, the limited number of studies precluded a deeper analysis of this association. These data highlight the need for more rigorous and longitudinal investigations of the relationship between FIS and hypertension in adult and pediatric populations.

Abstract
Nutrition in pregnancy and early childhood affects later blood pressure and precursors of atherosclerosis, but its influence on arterial stiffness is unexplored. This study determines whether exposure to improved nutrition during early life influences Augmentation index (AI) and pulse wave velocity (PWV) in mid-adulthood. We included 1221 adults (37-54y) who participated in a cluster-randomized nutritional supplementation trial of a protein-energy beverage (Atole), conducted between 1969–1977 in Guatemala. The comparison group received Fresco, a low-calorie protein-free beverage. In 2015–17, we measured anthropometry (weight, height, and waist-to-height ratio); AI and PWV (using carotid—femoral tonometry); blood pressure; fasting plasma glucose and serum lipids; and sociodemographic characteristics. Based on patterns of exposure, we characterized participants as fully, partially or unexposed to the intervention from conception to their second birthday (the ‘first 1000 days’). We fit pooled and sex-specific models using intention-to-treat, difference-in-difference regression analysis to test whether exposure to the supplement in the first 1000 days was associated with AI and PWV in adulthood adjusting for basal and current sociodemographic variables and current life-style and cardio-metabolic risk factors. Prevalence of obesity in men and women was 39.6% and 19.6%, and prevalence of hypertension was 44.0% and 36.0%, respectively. Women had higher AI (34.4±9.6%) compared to men (23.0± 9.8%), but had similar PWV (7.60±1.13 m/s and 7.60±1.31, respectively). AI did not differ significantly across intervention groups. PWV was lower in individuals with full exposure to the supplement during the first 1000 days (-0.39m/s, 95% CI -0.87, 0.09; p = 0.1) compared to unexposed individuals. This difference was similar after adjusting for cardio-metabolic risk factors (-0.45m/s; 95%C-0.93, 0.01; p = 0.06). Exposure to improved nutrition during the first 1000 days was marginally associated with lower PWV, but not with AI.

The modifying role of physical activity in the cross-sectional and longitudinal association of health-related quality of life with physiological functioning-based latent classes and metabolic syndrome. Health Qual Life Outcomes 2020; 18:345. [PMID: 33081800 PMCID: PMC7574351 DOI: 10.1186/s12955-020-01557-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 09/09/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Single cardio-metabolic risk factors are each known modifiable risk factors for adverse health and quality of life outcomes. Yet, evidence on the clustered effect of these parameters and the metabolic syndrome (MetS) on health-related quality of life (HRQoL) is still limited and mostly cross-sectional. The objectives of this study were to identify clusters of cardio-metabolic physiological functioning, to assess their associations with HRQoL in comparison with the MetS, to elucidate the modifying role of physical activity, and to assess differences in health service utilization. METHODS This study is based on longitudinal data from two time points (2010/11 & 2017/18) of the Swiss Study on Air Pollution and Lung and Heart Diseases (SAPALDIA). Latent class analysis (LCA) grouped participants based on a priori selected cardio-metabolic and MetS related physiological functioning variables (Body mass index, body fat, glycated hemoglobin, blood triglycerides, blood pressure). The 36-item Short-Form Health Survey (SF-36) was used to assess HRQoL. Quantile regressions were performed with and without adjustment for physical activity, to detect independent associations of the latent classes, MetS and physical activity with HRQoL. To assess the modifying role of physical activity, we additionally grouped participants based on the combination of physical activity and latent classes or MetS, respectively. Logistic regressions were used to investigate health service utilization as outcome. RESULTS The LCA resulted in three classes labeled "Healthy" (30% of participants in 2017/18), "At risk" and "Unhealthy" (29%). The Unhealthy class scored lowest in all physical component scores of HRQoL. Compared to healthy and active participants, inactive participants in the "Unhealthy" class showed lower scores in the physical functioning domain both cross-sectionally (- 9.10 (- 12.02; - 6.18)) and longitudinally. This group had an odds ratio of 2.69 (1.52; 4.74) for being hospitalized in the previous 12 months. CONCLUSIONS These results point to subjects with adverse cardio-metabolic physiological functioning and low activity levels as an important target group for health promotion and maintenance of well-being. The promotion of physical activity at the early stages of aging seems pivotal to mitigate the impact of the MetS on HRQoL at higher age.

Abstract
OBJECTIVE To assess the effect of dissemination and implementation of an intervention consisting of practice facilitation and a risk-stratified, population management dashboard on cardiovascular risk reduction for patients at high risk in small, primary care practices. STUDY SETTING A total of 219 small primary care practices (≤10 clinicians per site) across North Carolina with primary data collection from electronic health records (EHRs) from the fourth quarter of 2015 through the second quarter of 2018. STUDY DESIGN We performed a stepped-wedge, stratified, cluster randomized trial of a one-year intervention consisting of practice facilitation utilizing quality improvement techniques coupled with a cardiovascular dashboard that included lists of risk-stratified adults, aged 40-79 years and their unmet treatment opportunities. The primary outcome was change in 10-Year ASCVD Risk score among all patients with a baseline score ≥10 percent from baseline to 3 months postintervention. DATA COLLECTION/ EXTRACTION METHODS Data extracts were securely transferred from practices on a nightly basis from their EHR to the research team registry. PRINCIPLE FINDINGS ASCVD risk scores were assessed on 437 556 patients and 146 826 had a calculated 10-year risk ≥10 percent. The mean baseline risk was 23.4 percent (SD ± 12.6 percent). Postintervention, the absolute risk reduction was 6.3 percent (95% CI 6.3, 6.4). Models considering calendar time and stepped-wedge controls revealed most of the improvement (4.0 of 6.3 percent) was attributable to the intervention and not secular trends. In multivariate analysis, male gender, age >65 years, low-income (<$40 000), and Black race (P < .001 for all variables) were each associated with greater risk reductions. CONCLUSION A risk-stratified, population management dashboard combined with practice facilitation led to substantial reductions of 10-year ASCVD risk for patients at high risk. Similar approaches could lead to effective dissemination and implementation of other new evidence, especially in rural and other under-resourced practices. Registration: ClinicalTrials.Gov 15-0479.

Abstract
Uncontrolled hypertension is a leading contributor to cardiovascular disease. A cluster-randomized trial in 16 primary care clinics showed that 12 months of home blood pressure telemonitoring and pharmacist management lowered blood pressure more than usual care (UC) for 24 months. We report cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, hospitalized heart failure, coronary revascularization, and cardiovascular death) and costs over 5 years of follow-up. In the telemonitoring intervention (TI group, n=228), there were 15 cardiovascular events (5 myocardial infarction, 4 stroke, 5 heart failure, 1 cardiovascular death) among 10 patients. In UC group (n=222), there were 26 events (11 myocardial infarction, 12 stroke, 3 heart failure) among 19 patients. The cardiovascular composite end point incidence was 4.4% in the TI group versus 8.6% in the UC group (odds ratio, 0.49 [95% CI, 0.21-1.13], P=0.09). Including 2 coronary revascularizations in the TI group and 10 in the UC group, the secondary cardiovascular composite end point incidence was 5.3% in the TI group versus 10.4% in the UC group (odds ratio, 0.48 [95% CI, 0.22-1.08], P=0.08). Microsimulation modeling showed the difference in events far exceeded predictions based on observed blood pressure. Intervention costs (in 2017 US dollars) were $1511 per patient. Over 5 years, estimated event costs were $758 000 in the TI group and $1 538 000 in the UC group for a return on investment of 126% and a net cost savings of about $1900 per patient. Telemonitoring with pharmacist management lowered blood pressure and may have reduced costs by avoiding cardiovascular events over 5 years.

Abstract
PURPOSE OF REVIEW Summarize the methods used for measurement of cerebral blood flow and oxygenation; describe the effects of hypertension on cerebral blood flow and oxygenation. RECENT FINDINGS Information regarding the effects of hypertension on cerebrovascular circulation during exercise is very limited, despite a plethora of methods to help with its assessment. In normotensive individuals performing incremental exercise testing, total blood flow to the brain increases. In contrast, the few studies performed in hypertensive patients suggest a smaller increase in cerebral blood flow, despite higher blood pressure levels. Endothelial dysfunction and increased vasoconstrictor concentration, as well as large vessel atherosclerosis and decreased small vessel number, have been proposed as the underlying mechanisms. Hypertension may adversely impact oxygen and blood delivery to the brain, both at rest and during exercise. Future studies should utilize the newer, noninvasive techniques to better characterize the interplay between the brain and exercise in hypertension.

Abstract
CONTEXT High blood pressure is one of the leading preventable causes of cardiovascular death worldwide. In this regard, several studies have shown interest in the benefits of isometric exercise on blood pressure regulation. OBJECTIVE To assess whether low-intensity isometric handgrip exercise (LI-IHE) is an effective strategy to lower blood pressure levels in prehypertensive and hypertensive patients. DATA SOURCE This study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and registered with PROSPERO. Potentially eligible studies were identified after a systematic search conducted on 4 international databases: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), PEDro, and SPORTDiscus. STUDY SELECTION We included randomized controlled trials that comprised patients who received LI-IHE. STUDY DESIGN Systematic review with meta-analysis. LEVEL OF EVIDENCE Level 3. DATA EXTRACTION Data related to patient characteristics, exercise programs, risk-of-bias assessment, and outcomes of interest were systematically reviewed independently by 2 authors. RESULTS The following reductions (mean differences) were observed after LI-IHE: systolic blood pressure (SBP), (MD) = -5.43 mm Hg; (95% CI, -8.47 to -2.39; P = 0.0005); diastolic blood pressure (DBP), -2.41 mm Hg (95% CI, -4.33 to -0.48; P = 0.01); mean arterial pressure (MAP), -1.28 mm Hg (95% CI, -2.99 to 0.44; P = 0.14). CONCLUSION LI-IHE seems to lower SBP, DBP, and MAP values in prehypertensive and hypertensive adults. It appears that LI-IHE reduces, in greater magnitude, blood pressure levels in hypertensive patients, specifically in patients aged <45 years, those who are overweight, and those on medications. Nevertheless, substantial heterogeneity in the main results and in the analyses by subgroups generated uncertainty about the real reduction magnitude that LI-IHE can produce on blood pressure.
