Pulse Pressure and Cardiovascular and Kidney Outcomes by Age in the Chronic Renal Insufficiency Cohort (CRIC). Am J Hypertens 2025; 38:129-138. [PMID: 39437324 PMCID: PMC11735469 DOI: 10.1093/ajh/hpae136] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 08/20/2024] [Accepted: 10/02/2024] [Indexed: 10/25/2024] Open
Abstract
BACKGROUND Wide pulse pressure (PP) is associated with cardiovascular events and the progression of chronic kidney disease (CKD) to kidney failure. PP naturally widens with age, but it is unclear whether the risks associated with greater PP are the same across all ages. METHODS We used Cox proportional hazards models to investigate the association of PP with (i) atherosclerotic cardiovascular disease (ASCVD) events or death and (ii) a 50% reduction in estimated glomerular filtration rate or kidney failure in the chronic renal insufficiency cohort (CRIC). We evaluated the association of time-updated PP with these outcomes, accounting for time-updated confounders using inverse probability weighting. RESULTS Among 5,621 participants with CKD, every 10-mmHg greater PP was associated with a 6% higher risk of an ASCVD event or death (hazard ratio [HR] = 1.06, 95% CI 1.04, 1.08) and 17% higher risk of the composite kidney outcome (HR = 1.17, 95% CI 1.16, 1.18). Greater PP was associated with a higher risk of ASCVD events or death among participants in the lowest age tertile (21-61 years), but a higher risk of the composite kidney outcome in the oldest age tertile (71-79 years). While wide PP in participants that experienced the primary outcomes was predominantly driven by elevated SBP, PP remained significantly associated with the composite kidney outcome across all ages and with ASCVD events or death in the first age tertile when SBP was added to the Cox regression model. CONCLUSIONS Our findings suggest that the mechanism by which PP is associated with adverse outcomes may differ by age.

[PMID: 39228619 PMCID: PMC11368296 DOI: 10.4103/jfmpc.jfmpc_1563_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 12/30/2023] [Accepted: 02/02/2024] [Indexed: 09/05/2024] Open
Abstract
Background Cardiovascular diseases (CVD) account for approximately one-third of all deaths worldwide. The incidence of cardiovascular events such as myocardial infraction has been reported to be progressively increasing with age, especially with existing comorbidities such as hypertension, diabetes and obesity. Assessing arterial stiffness indices may serve as a screening tool in identification of population at risk of cardiovascular diseases and assist in implementation of preventive measures and early treatment in this population. Objectives To measure and compare the arterial stiffness indices in healthy adults with diabetes, hypertension and obesity. Methods A total of 184 adults in the age group of 30-50 years were included in the study who were divided into 4 groups: Group I (n = 64) (diabetic), group II (n = 40) (hypertensives), group III (n = 40) (obese) and group IV (n = 40) (control). The arterial stiffness indices were measured by using a certified oscillometric device in all the participants. Results The arterial stiffness indices were assessed by using a certified oscillometric device in all the participants. The mean values of right baPWV and left baPWV are found to be significantly higher in hypertensive subjects compared with obese, diabetic and healthy controls. Conclusion The pulse wave velocity, ASI and pulse pressure serve as independent predictors of cardiovascular mortality and outcomes in hypertension, diabetes and obesity as well as healthy individuals.

Abstract
Prevention of cardiovascular disease (CVD) remains one of the largest public health challenges of our time. Identifying individuals at increased cardiovascular risk at an asymptomatic, sub-clinical stage is of paramount importance for minimizing disease progression as well as the substantial health and economic burden associated with overt CVD. Vascular ageing (VA) involves the deterioration in vascular structure and function over time and ultimately leads to damage in the heart, brain, kidney, and other organs. Vascular ageing encompasses the cumulative effect of all cardiovascular risk factors on the arterial wall over the life course and thus may help identify those at elevated cardiovascular risk, early in disease development. Although the concept of VA is gaining interest clinically, it is seldom measured in routine clinical practice due to lack of consensus on how to characterize VA as physiological vs. pathological and various practical issues. In this state-of-the-art review and as a network of scientists, clinicians, engineers, and industry partners with expertise in VA, we address six questions related to VA in an attempt to increase knowledge among the broader medical community and move the routine measurement of VA a little closer from bench towards bedside.

Gierach M, Junik R. The Level of Intima-Media Thickness in Patients with Metabolic Syndrome in Poland Depending on the Prevalence of Type 2 Diabetes. Biomedicines 2023; 11:1510. [PMID: 37371604 DOI: 10.3390/biomedicines11061510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/18/2023] [Accepted: 05/20/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND Metabolic syndrome (MetS), increasingly diagnosed among the Polish population, is a combination of factors that are associated with an increased risk of atherosclerosis and cardiovascular diseases. Intima-media thickness (IMT) of the common carotid artery has been suggested as, simply, a non-invasive and reproducible marker of the early stages of the atherosclerotic process. The carotid IMT can also be a strong predictor of future cerebral and cardiovascular events. The aim of our study was to evaluate atherosclerotic lesions in carotid vessels in patients with MetS depending on the presence of DMt2 and to assess which demographic factors affect the level of IMT. The study involved 335 subjects diagnosed with MetS, including 211 females (65%) and 124 males (37%) aged 37-82. The diagnosis of MetS was made on the basis of the International Diabetes Federation (IDF) criteria. The patients were divided into two subgroups: with DMt2 and without DMt2. The value of IMT depended on gender, education, and smoking status. We noticed that patients with DMt2 had the highest measurement of IMT compared with other groups (1.01 vs. 0.98). Additionally, a statistically significant difference between the subgroup with DMt2 and those without DMt2 was found (1.01 vs. 0.92; p < 0.005). Ultrasound assessment of the carotid IMT should be used more often in the diagnosis and monitoring of high cardiovascular risk and early progression of atherosclerosis, especially in patients with MetS with current DMt2.

Abstract
BACKGROUND Less is known regarding the association of pulse pressure (PP) with memory function. This study aimed to characterize long-term patterns of PP in middle-aged and older adults and explore their impact on subsequent change in memory function. METHODS Data from the English Longitudinal Study of Ageing (ELSA, 2004-2018), were analyzed. Totally, 3587 dementia-free participants with three measurements of BP were included. All three visits of PP (2004-2012) were used to characterize longitudinal patterns of PP by group-based trajectory modeling (GBTM). Generalized estimating equation (GEE) models were fitted to explore the impact of PP trajectories on change in memory over a subsequent 6-year period (2012-2018). RESULTS Using GBTM, three distinct trajectories of PP were identified: low-stable (38.1%), moderate-stable (48.6%), and elevated-increasing group (13.3%). GEE model suggested that memory declined over a 6-year period in all PP trajectories (all Ptime <0.001). The overall interactions between patterns of PP changes and time with memory were statistically significant (χ2 interaction = 20.69, p = 0.002). Compared to participants in the low-stable group, those in the moderate-stable and elevated-increasing group exhibited a faster decline in memory. CONCLUSIONS Longitudinal patterns of moderate-stable and elevated-increasing PP were associated with an accelerated decrease in memory. Controlling BP instability may be a promising interventional strategy for preventing cognitive decline among older adults.

Abstract
BACKGROUND Dysbiosis of gut microbiota plays a pivotal role in vascular dysfunction and microbial diversity was reported to be inversely correlated with arterial stiffness. However, the causal role of gut microbiota in the progression of arterial stiffness and the specific species along with the molecular mechanisms underlying this change remain largely unknown. METHODS Participants with elevated arterial stiffness and normal controls free of medication were matched for age and sex. The microbial composition and metabolic capacities between the 2 groups were compared with the integration of metagenomics and metabolomics. Subsequently, Ang II (angiotensin II)-induced and humanized mouse model were employed to evaluate the protective effect of Flavonifractor plautii (F plautii) and its main effector cis-aconitic acid. RESULTS Human fecal metagenomic sequencing revealed a significantly high abundance and centrality of F plautii in normal controls, which was absent in the microbial community of subjects with elevated arterial stiffness. Moreover, blood pressure only mediated part of the effect of F plautii on lower arterial stiffness. The microbiome of normal controls exhibited an enhanced capacity for glycolysis and polysaccharide degradation, whereas, those of subjects with increased arterial stiffness were characterized by increased biosynthesis of fatty acids and aromatic amino acids. Integrative analysis with metabolomics profiling further suggested that increased cis-aconitic acid served as the main effector for the protective effect of F plautii against arterial stiffness. Replenishment with F plautii and cis-aconitic acid improved elastic fiber network and reversed increased pulse wave velocity through the suppression of MMP-2 (matrix metalloproteinase-2) and inhibition of MCP-1 (monocyte chemoattractant protein-1) and NF-κB (nuclear factor kappa-B) activation in both Ang II-induced and humanized model of arterial stiffness. CONCLUSIONS Our translational study identifies a novel link between F plautii and arterial function and raises the possibility of sustaining vascular health by targeting gut microbiota.

Abstract
Background Cardiovascular disease (CVD) is the foremost cause of morbidity and deaths in antiphospholipid syndrome (APS), driven by thrombo-inflammation and atherothrombosis mechanisms. Metabolic syndrome (MetS) is a proinflammatory and prothrombotic state characterized by increased CVD risk. We aimed to evaluate the prevalence of MetS in APS patients compared to rheumatoid arthritis (RA) and diabetes mellitus (DM) and its associations with clinical and laboratory patient characteristics and vascular ultrasound (US) markers of subclinical atherosclerosis. Methods We included 414 patients in our study: 138 patients with APS (median age: 44.9 years, females 70%) and matched 1:1 for age and sex RA and DM subjects. Three sets of criteria were used for MetS diagnosis: Joint Interim Statement (JIS), International Diabetes Federation (IDF) and modified National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). The demographic, clinical and laboratory characteristics of all participants were recorded and carotid and femoral US was performed in patients with APS. Multivariate regression models were applied. Results Prevalence of MetS was 23.9%, 23.2%, 20.3% (based on JIS, IDF, modified NCEP-ATPIII criteria, respectively) in APS versus 17.4%, 17.4%, 13% in RA (p=0.181, p=0.231, p=0.106, respectively), and 44.2%, 44.2%, 40.6% in DM patients. In multivariate analysis, patients with systemic lupus erythematosus- related APS had an approximately 2.5-fold higher risk of MetS versus RA patients. MetS in APS was independently associated with arterial thrombosis (Odds ratio 3.5, p=0.030). Odds ratio for MetS was 1.16 for each one unit increase in C-reactive protein levels according to JIS and IDF criteria, and 1.49 and 1.47 for each one unit increase in uric acid levels using the IDF and modified NCEP-ATPIII models, respectively. APS patients with atherosclerotic carotid plaques had 4 to 6.5-fold increased risk of MetS. Odds for MetS were decreased by 26% with an increase in physical activity by one hour per week. Conclusions MetS is present in approximately one-fourth of APS patients at a comparable prevalence to that observed in patients with RA. MetS in APS is associated with arterial thrombosis, cardiovascular risk biomarkers, physical activity, and subclinical atherosclerosis, supporting its role in cardiovascular risk stratification and management in APS.

Combining Aortic Size With Arterial Hemodynamics Enhances Assessment of Future Thoracic Aortic Aneurysm Expansion. Can J Cardiol 2023; 39:40-48. [PMID: 36374804 DOI: 10.1016/j.cjca.2022.09.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 09/08/2022] [Accepted: 09/13/2022] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Thoracic aortic aneurysm (TAA) is a deadly disease whose current method for risk stratification (aneurysm size) is imperfect. We sought to evaluate whether combining aortic size with hemodynamic measures that reflect the aorta's function was superior to aortic size alone in the assessment of TAA expansion. METHODS One hundred thirty-seven nonoperated participants with TAA were followed prospectively. Aortic stiffness and pulsatile hemodynamics were noninvasively assessed at baseline with a combination of arterial tonometry with echocardiography using validated methodology. Aneurysm growth was calculated from standard imaging modalities. Multivariable linear regression models adjusted for potential confounders evaluated the association of aneurysm size and arterial hemodynamics, alone and in combination, with TAA growth. RESULTS Sixty-nine percent of participants were male. Mean ± SD age, baseline aneurysm size, follow-up, and aneurysm expansion were, respectively, 62.2 ± 11.4 years, 45.9 ± 4.0 mm, 4.5 ± 1.9 years, and 0.41 ± 0.46 mm/year. In the linear regression models, the standardised β (β∗) for the association of aneurysm size with aneurysm expansion was 0.178 (P = 0.044). This was improved by combining aortic size with most measures of aortic function, with β∗ ranging from 0.192 (for aneurysm size combined with central diastolic blood pressure) to 0.484 (for aneurysm size combined with carotid-femoral pulse-wave velocity) (P ≤ 0.05 for each). CONCLUSIONS Combining aneurysm size with measures of arterial function improves assessment of aneurysm growth over TAA size alone, which is the standard for clinical decisions in TAA. Thus, combining aneurysm size with measures of aortic function provides a clinical advantage in the assessment of TAA disease activity.

Abstract
OBJECTIVE Studies on the mutual relationship between blood pressure (BP) variability and arterial stiffness using time-dependent changes in arterial stiffness are scarce. METHODS In this prospective cohort of Korean patients with chronic kidney disease (CKD) G1-G5 without kidney replacement therapy, we studied the bidirectional association between visit-to-visit SBP variability (VVSV) and arterial stiffness in 1036 participants who underwent brachial-ankle pulse wave velocity (baPWV) measurement at baseline and year four. We constructed multivariable logistic regression models using two analytical sets. First, we determined the VVSV [standard deviation (SD)] of all SBP readings over 4 years, and then calculated the odds ratios (ORs) for arterial stiffness progression according to tertiles of VVSV. Arterial stiffness progression was defined as at least 75th percentile of the difference in baPWV between baseline and year four. Second, we analysed the ORs for at least 75th percentile of the 4-year VVSV according to tertiles of baseline baPWV. RESULTS Compared with the lowest tertile of VVSV (SD), the ORs [95% confidence interval (95% CI)] for arterial stiffness progression were 1.42 (0.96-2.10) and 1.64 (1.11-2.43) for the middle and highest tertiles, respectively. In the second analysis based on tertiles of baseline baPWV, the ORs for at least 75th percentile of VVSV (SD) were 1.41 (95% CI, 0.95-2.10) and 1.64 (95% CI, 1.04-2.61) for the middle and highest tertiles, respectively. This association was similar in both analytical models when VVSV and baPWV were treated as continuous variables. CONCLUSION There is a bidirectional relationship between BP variability and arterial stiffness in patients with CKD.

Abstract
The aim of this study was to conduct a bibliometric analysis of the scientific articles on advanced glycation end products (AGEs) and obesity. English-language journal articles about AGEs and obesity were retrieved from the Scopus database. The OpenRefine application was used for data cleaning, the VOSviewer software program for analysis of the trends of year of publication, country, institution, journal, authors, references, and keywords. Microsoft Excel and Tableau Public were applied for the visualizing of the publication trends. Data collection was performed on 3 February 2022, from a total of 1170 documents. The Mann−Whitney test and Spearman test with software SPSS ver.28.0.1.1. were used to assess the relation between open access journal statuses, years of publications, and CiteScore. The results of the study showed that there was an increase in studies on processed foods, including AGEs and obesity. The United States was the country with the largest contribution in this field, with the highest number of citations. The Nutrients journal published the largest number of articles on this topic, particularly in the last two years. The present focus of the studies is on ultra-processed foods. The open access journals have younger medians of the year of publication and higher medians for number of citations than do closed access journals (p < 0.001 and p < 0.05, respectively). A strong negative association was seen between CiteScore and the year of publication (r = −0.64 [95% CI: −0.67, −0.60]), p < 0.001. We present this bibliometric analysis to furnish the most recent data on the description, visualization, and analysis of AGEs and obesity.

Abstract
BACKGROUND The dualistic diagnostic criteria for metabolic syndrome overlooked the severity of metabolic syndrome, and the relationships between the severity of metabolic syndrome and adverse health conditions are poorly characterized. We therefore aimed to investigate the associations of metabolic syndrome severity with incident cardiovascular disease (CVD)/all-cause mortality. METHODS A total of 116,772 participants from the Kailuan study were followed up biennially between 2006 and 2018. The severity of metabolic syndrome was evaluated using a continuous metabolic syndrome severity score (MetS score). Cox proportional hazards model was used to examine the association between MetS score and the risk of CVD and all-cause mortality. Restricted cubic spline analyses were performed to explore the dose-response associations. RESULTS We found that the risk of CVD and all-cause mortality increased consistently with the MetS score. In the multivariable-adjusted model, the hazard ratios of CVD and all-cause mortality were 2.05 (95% CI 1.86-2.25) and 1.45 (95% CI 1.35-1.56), respectively, in those subjects>75th percentile compared with those <25th percentile. Additionally, a J-shaped dose-response relationship was found between MetS score and the risk of all-cause mortality (pnonlinearity <.001), while a linear relationship between MetS score and the risk of CVD was observed in this study (pnonlinearity = .737). CONCLUSIONS This study suggests significant dose-response relationships between MetS score and the risk of CVD/mortality. Subjects without metabolic syndrome but with a relatively high MetS score should raise their awareness and pay more attention to the possible increased risk of CVD events.

FRONTIERS IN OPHTHALMOLOGY 2022; 2:947571. [PMID: 38983568 PMCID: PMC11182107 DOI: 10.3389/fopht.2022.947571] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 07/29/2022] [Indexed: 07/11/2024]
Abstract
Prolonged hyperglycemia causes long-term vision complications and an increased risk of cognitive deficits. High blood sugar also confers an osmotic load/stress to cells. We assessed behavioral and neurochemical changes in zebrafish brain and retina following prolonged hyperglycemia for 4-weeks or 8-weeks. At each time point, behavior was assessed using 3-chamber choice task and optomotor response; tissue was then collected and levels of inflammatory markers, tight junction proteins, and neurotransmitters determined using Western Blots. After 4-weeks, brain levels of v-rel reticuloendotheliosis viral oncogene homolog A (avian) (RelA; NF-kB subunit), IkB kinase (IKK), and glial fibrillary acidic protein (GFAP) were significantly elevated; differences in zonula occludens-1 (ZO-1), claudin-5, glutamic acid decarboxylase (GAD), and tyrosine hydroxylase (TH) were not significant. In retina, significant differences were observed only for TH (decreased), Rel A (increased), and GFAP (increased) levels. Glucose-specific differences in initial choice latency and discrimination ratios were also observed. After 8-weeks, RelA, GAD, and TH were significantly elevated in both tissues; IKK and GFAP levels were also elevated, though not significantly. ZO-1 and claudin-5 levels osmotically decreased in retina but displayed an increasing trend in glucose-treated brains. Differences in discrimination ratio were driven by osmotic load. OMRs increased in glucose-treated fish at both ages. In vivo analysis of retinal vasculature suggested thicker vessels after 4-weeks, but thinner vessels at 8-weeks. In vitro, glucose treatment reduced formation of nodes and meshes in 3B-11 endothelial cells, suggesting a reduced ability to form a vascular network. Overall, hyperglycemia triggered a strong inflammatory response causing initial trending changes in tight junction and neuronal markers. Most differences after 4-weeks of exposure were observed in glucose-treated fish suggesting effects on glucose metabolism independent of osmotic load. After 8-weeks, the inflammatory response remained and glucose-specific effects on neurotransmitter markers were observed. Osmotic differences impacted cognitive behavior and retinal protein levels; protein levels in brain displayed glucose-driven changes. Thus, we not only observed differential sensitivities of retina and brain to glucose-insult, but also different cellular responses, suggesting hyperglycemia causes complex effects at the cellular level and/or that zebrafish are able to compensate for the continued high blood glucose levels.

Abstract
UNLABELLED A growing body of research examines the effect of aerobic exercise on pulse wave velocity (PWV) in middle-aged and elderly people, while findings of available studies were conflicting. The aim of this study was to explore the effect of aerobic exercise on PWV in middle-aged and elderly people. Searches were performed in PubMed, Web of Science, and EBSCO databases. Cochrane risk assessment tool was used to evaluate the methodological quality of the included literature. We included studies that satisfied the following criteria: (1) eligible studies should be randomized controlled trials (RCTs); (2) eligible studies should include both an intervention and a control group; (3) eligible studies should use the middle-aged or elderly people as subjects; and (4) eligible studies should use PWV as the outcome measure. From 972 search records initially identified, 11 studies with a total of 12 exercise groups (n = 245) and 11 control groups (n = 239) were eligible for meta-analysis. There was a significant effect of aerobic exercise on reducing PWV in middle-aged and elderly people [weighted mean difference (WMD), -0.75 (95% CI, -1.21 to -0.28), p = 0.002]. Specifically, a higher intensity [vigorous-intensity, -0.74 (-1.34 to -0.14), p = 0.02; moderate-intensity, -0.68 (-1.49 to 0.12), p = 0.10], a younger age [45 years ≤ age < 60 years, -0.57 (-0.78 to -0.37), p < 0.00001; age ≥ 60 years, -0.91 (-2.10 to 0.27), p = 0.13], a better health status [healthy, -1.19 (-2.06 to -0.31), p = 0.008; diseased, -0.32 (-0.64 to -0.01), p = 0.04], and a lower basal body mass index (BMI) [BMI < 25, -1.19 (-2.06 to -0.31), p = 0.008; 25 ≤ BMI < 30, -0.52 (-0.92 to -0.12), p = 0.01; BMI ≥ 30, -0.09 (-0.93 to 0.76), p = 0.84] were associatedwith larger reductions in PWV. Aerobic exercise, especially vigorous-intensity aerobic exercise, contributed to reducing PWV in middle-aged and elderly people. The effect of aerobic exercise on improving PWV was associated with characteristics of the participants. Specifically, a younger age, a better health status, and a lower basal BMI contributed to more significant reductions in PWV.

Abstract
The metabolic syndrome (MetS) has been well linked with coronary heart disease (CHD) in the general population, but studies have rarely explored their association among patients with stroke. We examine prevalence of MetS and its association with CHD in patients with first-ever ischemic stroke. This hospital-based study included 1851 patients with first-ever ischemic stroke (mean age 61.2 years, 36.5% women) who were hospitalized into two university hospitals in Shandong, China (January 2016–February 2017). Data were collected through interviews, physical examinations, and laboratory tests. MetS was defined following the National Cholesterol Education Program (NCEP) criteria, the International Diabetes Federation (IDF) criteria, and the Chinese Diabetes Society (CDS) criteria. CHD was defined following clinical criteria. Data were analyzed using binary logistic regression models. The overall prevalence of MetS was 33.4% by NECP criteria, 47.2% by IDF criteria, and 32.5% by CDS criteria, with the prevalence being decreased with age and higher in women than in men (p < 0.05). High blood pressure, high triglycerides, and low HDL-C were significantly associated with CHD (multi-adjusted odds ratio [OR] range 1.27–1.38, p < 0.05). The multi-adjusted OR of CHD associated with MetS defined by the NECP criteria, IDF criteria, and CDS criteria (vs. no MetS) was 1.27 (95% confidence interval 1.03–1.57), 1.44 (1.18–1.76), and 1.27 (1.03–1.57), respectively. In addition, having 1–2 abnormal components (vs. none) of MetS was associated with CHD (multi-adjusted OR range 1.66–1.72, p < 0.05). MetS affects over one-third of patients with first-ever ischemic stroke. MetS is associated with an increased likelihood of CHD in stroke patients.

Abstract
Cardiovascular diseases (CVD) are the leading cause of mortality in modernized societies. Arterial stiffening with aging and disease is a key pathological event leading to increased CVD morbidity and mortality. Perivascular adipose tissue (PVAT) is a fat depot not widely studied yet has direct and profound effects on arterial stiffening. Identifying PVAT as a novel therapeutic target to lower arterial stiffness and thereby CVD risk has potentially important clinical ramifications. Thus, herein, we will overview the current preclinical evidence and the associated mechanisms for PVAT to promote arterial stiffness with aging and other disease conditions. We will also discuss viable translational lifestyle and pharmacological interventions for altering PVAT function that may de-stiffen arteries. Last, the translational potential for PVAT as a therapeutic target to lower arterial stiffness and CVD risk for clinical populations will be discussed.

Abstract
BACKGROUND AND AIMS Glucose and lipoprotein(a) [Lp(a)] have been recognized risk factors for atherosclerosis. The impact of both factors on fatty liver patients has not been studied. The aim of this study is to explore the role of high-level Lp(a) and different glucose metabolism statuses on carotid plaques in fatty liver patients. METHODS We selected 4,335 fatty liver patients in this cross-sectional study. The diagnosis of fatty liver disease and carotid plaques was made by ultrasound. Participants were divided into four groups based on glucose metabolism status (normal glucose regulation [NGR], lower bound of impaired fasting glucose [IFG-L], higher bound of impaired fasting glucose [IFG-H], diabetes mellitus [DM]) and then categorized into 12 subgroups according to Lp(a) concentrations. The association between variables was estimated by odds ratio (OR). RESULTS Carotid plaques were present in 1,613 (37.2%) fatty liver patients. Lp(a)≥30 mg/dL was associated with high risk of carotid plaques in those patients with IFG-L, IFG-H and DM (OR 1.934 [95% CI 1.033-3.618], 2.667 [1.378-5.162], 4.000 [2.219-7.210], respectively; p<0.05). Fatty liver patients with DM plus Lp(a)<10 mg/dL and 10≤Lp(a)<30 mg/dL were more vulnerable to carotid plaques (OR 1.563 [95% CI 1.090-2.241], 1.930 [1.279-2.914]), respectively, p<0.05). CONCLUSIONS Our study first suggested that high-level Lp(a) may raise the risk of carotid plaques in fatty liver patients with not only diabetes but also IFG, manifesting that Lp(a) may be helpful for the early discovery of subclinical atherosclerosis in fatty liver patients with impaired glucose metabolism.

Abstract
The impact of age and 24‐h ambulatory blood pressure (ABPM) on arterial stiffness and carotid intima‐media thickness (cIMT) in ischemic stroke patients younger than 60 years of age is poorly explored. A total of 385 acute ischemic stroke patients (aged 49.6±9.7 years, 68% men) were prospectively included and grouped in younger (15–44 years, n = 93) and middle‐aged (45–60 years, n = 292). Arterial stiffness was measured by carotid‐femoral pulse wave velocity (PWV), and cIMT by carotid ultrasound. 24‐h ABPM was recorded. The middle‐aged stroke patients had higher prevalence of smoking, hypertension, diabetes mellitus, metabolic syndrome and hypercholesterolemia, and had higher PWV and cIMT (all p < .05). In multivariable linear regression analyses adjusted for sex, BMI, smoking, diabetes mellitus, total cholesterol, high‐density lipoprotein cholesterol, triglycerides, eGFR, systolic BP and concomitant antihypertensive treatment, 1SD (4.4 years) higher age was associated with higher PWV (β = 0.44,R2 = 0.46, p < .001) in the younger group, and with higher mean cIMT (β = 0.16, R2 = 0.21, p = .01) in the middle‐aged group. In the middle‐aged group, 24‐h pulse pressure had a significant association with PWV (β = 0.18, R2 = 0.19, p = .009), while the association with cIMT was attenuated (β = 0.13, R2 = 0.16, p = .065). 24‐h diastolic BP was associated with higher cIMT in the middle‐aged group (β = 0.24, p < .001, R2 = 0.23), but not with PWV in either age groups. Among ischemic stroke patients < 60 years, higher age was associated with increased arterial stiffness for patients up to age 44 years, and with cIMT in middle‐aged patients. 24‐h pulse pressure was associated with arterial stiffness, and 24‐h diastolic BP was associated with cIMT only in middle‐aged patients.

Evaluation of the Effects of Aging on the Aorta Stiffness in Relation with Mineral and Trace Element Levels: an Optimized Method via Custom-Built Stretcher Device.

Abstract
Aortic stiffness represents the major cause of aging and tightly associated with hypertension, atherosclerosis, cardiovascular diseases, and increased mortality. Mechanical characteristics of the aorta play a vital role in the blood flow, circulation, systolic pressure, and aortic stiffness; however, the correlation of trace element and mineral levels with aortic stiffness has not been studied before. Balance in the trace elements and minerals is vital for the biological functions; however, natural aging may alter this balance. Thus, after measuring aortic stiffness of aged and young rat aortas by a custom-built stretcher device, trace element and mineral levels were evaluated via ICP-MS. Also, biomarkers of aging including blood pressure, arterial pressure glucose, insulin levels, and histochemical parameters were investigated as well. Aortic stiffness, blood glucose, plasma insulin, systolic, diastolic, and mean arterial pressure significantly increased by aging in the aorta of aged rats compared with the young ones. Also, Fe, Al, Co, Ni, Zn, Sr, Na, Mg, and K levels increased in the aged aorta samples compared with the young aorta samples of rats. Increased levels of the indicated elements may be correlated with the development and progression of aortic stiffness and vascular complications. Thus, possible mechanisms correlating aortic stiffness with the imbalance in the trace element and mineral levels should be further investigated.

Abstract
Atherosclerosis comprises two components, atherosis and sclerosis, characterized by morphological wall thickening and functional stiffening, respectively, of the arterial wall. In recent years, much interest has been directed to the role of functional changes in large arteries, i.e., increased stiffness or decreased elasticity, on the development of cardiovascular diseases. In fact, the clinical evaluation of arterial stiffness is increasingly performed in patients with cardiovascular risk factors. Local arterial stiffness is measured using an ultrasound technique implemented with an echo-tracking system at the common carotid and femoral arteries. Several indices of local arterial stiffness are obtained by ultrasound, among which stiffness parameter β is unique because it is the least affected by blood pressure at the time of measurement. Evidence from cross-sectional studies indicates that increased stiffness parameter β is associated with a number of cardiovascular risk factors, such as older age, smoking, insufficient physical activity, hypertension, obesity, metabolic syndrome, insulin resistance, type 2 diabetes, chronic kidney disease, and comorbid cardiovascular disease. Results from several prospective observational studies also suggest that carotid stiffness parameter β is a useful surrogate marker of cardiovascular events and/or mortality, although the results differ depending on the characteristics of the study subjects. Furthermore, several interventional studies have shown that carotid stiffness parameter β improved after lifestyle modification or drug treatment. In this review, we summarize the current evidence of stiffness parameter β of the carotid artery and discuss its clinical implications as a marker of vascular health or as a predictor of cardiovascular outcomes.

Abstract
With an increase in the obese population, the prevalence of metabolic syndrome is increasing in Korea. This study aimed to identify sex- and age-specific risk factors for metabolic syndrome. A secondary data analysis was performed using the Korean National Health and Nutritional Examination Survey. Participants comprised 6144 adults aged 20-79 years. The prevalence of metabolic syndrome was high in the middle- and old-aged men (31.9% and 34.5%, respectively) and in old-aged women (39.1%). Risk factors for metabolic syndrome showed different patterns for men and women. In men, alcohol drinking was identified as the main risk factor for hypertension (odds ratio (OR); young = 3.3 vs. middle age = 2.0), high triglycerides (young = 2.4 vs. middle age = 2.2), and high fasting blood sugar (middle age = 1.6). In women, the main risk factors were household income and education level, showing different patterns in different age groups. In conclusion, the vulnerable groups at high risk of metabolic syndrome are those of middle-aged men and women. The pattern of risk factors is sex-specific.

Abstract
Background Common carotid intima medial thickness (IMT) increases with aging. However, the longitudinal association between IMT and other age-associated hemodynamic alterations in men and in women are not fully explored. Methods and Results We analyzed repeated measures of IMT, blood pressure, and carotid-femoral pulse wave velocity over a 20-year period in 1067 men and women of the Baltimore Longitudinal Study on Aging; participants were ages 20 to 92 years at entry and free of overt cardiovascular disease. Linear mixed-effects models were used to calculate the individual rates of change (Change) of IMT, pulse pressure, mean arterial pressure, and pulse wave velocity, among other covariates. Multivariate regression analysis was used to examine the association of IMTChange with baseline and rates of change of hemodynamic parameters and cardiovascular risk factors. IMT increased at accelerating rates from 0.02 mm/decade at age 50 years to 0.05 mm/decade at age 80 years greater rates in men than in women. IMTChange was positively associated with baseline low-density lipoprotein, low-density lipoproteinChange, and baseline systolic blood pressure and systolic blood pressureChange, but inversely with baseline diastolic blood pressure and diastolic blood pressureChange. When blood pressure was expressed as pulse pressure and MAP, IMTChange was positively associated with baseline pulse pressure and pulse pressureChange and inversely with baseline mean arterial pressure and mean arterial pressureChange. In sex-specific analysis, these associations were observed in women, but not in men. Conclusions In summary, our analyses showed that IMT increases at accelerating rates with aging. Age-associated changes in IMT were modulated by concurrent changes of low-density lipoprotein in both sexes, and of pulsatile and mean blood pressure in women but not men.

Abstract
Vascular smooth muscle cells (VSMCs), located in the media of artery, play key roles in maintaining the normal vascular physiological functions. Abnormality in VSMCs is implicated in vascular diseases (VDs), including atherosclerosis, abdominal aortic aneurysm (AAA), aortic dissection, and hypertension by regulating the process of inflammation, phenotypic switching, and extracellular matrix degradation. Sirtuins (SIRTs), a family of proteins containing seven members (from SIRT1 to SIRT7) in mammals, function as NAD+-dependent histone deacetylases and ADP-ribosyltransferases. In recent decades, great attention has been paid to the cardiovascular protective effects of SIRTs, especially SIRT1, suggesting a new therapeutic target for the treatment of VDs. In this review, we introduce the basic functions of SIRT1 against VSMC senescence, and summarize the contribution of SIRT1 derived from VSMCs in VDs. Finally, the potential new strategies based on SIRT1 activation have also been discussed with an emphasis on SIRT1 activators and calorie restriction to improve the prognosis of VDs.

Abstract
INTRODUCTION The metabolic syndrome (MetS) is an adverse metabolic state composed of obesity, hyperglycemia/pre-diabetes, hypertension, and dyslipidemia. It substantially increases the risk of type 2 diabetes, cardiovascular disease (CVD) and mortality, and has a huge impact on public health. AREA COVERED The present review gives an update on the definition and prevalence of MetS, and its impact on cardiac structure and function as well as on the brain and central arteries. The association with CVD and mortality risk is discussed. Focus is mainly directed toward the subclinical target organ damage related to MetS. Data is also critically reviewed to provide evidence on the incremental prognostic value of overall MetS over its individual components. EXPERT COMMENTARY MetS is a clinical risk condition associated with subclinical and clinical CVD and mortality. Roughly, 30% of the world population suffer from MetS. As all components of the MetS are modifiable, optimal preventive and therapeutic measures should be initiated to improve CV risk control, particularly aggressively treating hypertension and hyperglycemia, and encouraging people to adopt healthy lifestyle as early as possible is of great importance.

Abstract
Background: Identification of subclinical target organ damage (TOD) at early stage is important for the reduction in cardiovascular risk. This study was performed to assess the association between metabolic syndrome (MetS) and several types of TOD in urban people. Methods: Data from 958 Korean subjects without cardiovascular disease, living in Seoul city (mean age, 55.2 years, 47.6% males), were extracted from the prospective cohort database. All participants underwent extensive evaluation of TOD parameters, including left ventricular mass index (LVMI), E/e', brachial-ankle pulse wave velocity (baPWV), estimated glomerular filtration rate (eGFR), ankle-brachial index (ABI), carotid intima-media thickness (IMT), and obstructive coronary artery disease. Results: MetS and ≥1 TOD were detected in 494 (51.5%) and 329 (34.3%) subjects, respectively. There were no significant differences in the prevalence of ≥1 TOD according to the presence of MetS (P > 0.05). Among MetS components, only high blood pressure was associated with ≥1 TOD (69.6% vs. 59.9%, P = 0.004). There was a positive association between ≥1 TOD and the number of MetS traits (P = 0.034). There were significant linear correlations of Z-score of MetS with baPWV (r = 0.241, P < 0.001) and eGFR (r = -0.173, P < 0.001) but not with LVMI, E/e', ABI, and carotid IMT (P > 0.05 for each). Conclusions: In urban Korean population without cardiovascular disease, TOD is more closely related to the number of risk factors meeting MetS criteria and high blood pressure than the presence of MetS itself.

Abstract
AIMS/INTRODUCTION Electronegative low-density lipoprotein (L5) is the most atherogenic fraction of low-density lipoprotein and is elevated in people with metabolic syndrome (MetS), whereas the retinol-binding protein 4 receptor (stimulated by retinoic acid 6 [STRA6]) cascade is disrupted in various organs of patients with obesity-related diseases. Our objective was to investigate whether L5 from MetS patients capably induces pathogenesis of aorta through disrupting the STRA6 cascade. MATERIAL AND METHODS We examined the in vivo and in vitro effects of L5 on the STRA6 cascade and aortic atherogenic markers. To investigate the role of this cascade on atherosclerotic formation, crbp1 transfection was carried out in vitro. RESULTS This study shows that L5 activates atherogenic markers (p38 mitogen-activated protein kinases, pSmad2 and matrix metallopeptidase 9) and simultaneously suppresses STRA6 signals (STRA6, cellular retinol-binding protein 1, lecithin-retinol acyltransferase, retinoic acid receptor-α and retinoid X receptor-α) in aortas of L5-injected mice and L5-treated human aortic endothelial cell lines and human aortic smooth muscle cell lines. These L5-induced changes of the STRA6 cascade and atherogenic markers were reversed in aortas of LOX1-/- mice and in LOX1 ribonucleic acid-silenced human aortic endothelial cell lines and human aortic smooth muscle cell lines. Furthermore, crbp1 gene transfection reversed the disruption of the STRA6 cascade, the phosphorylation of p38 mitogen-activated protein kinases and Smad2, and the elevation of matrix metallopeptidase 9 in L5-treated human aortic endothelial cell lines. CONCLUSIONS This study shows that L5 from MetS patients induces atherogenic markers by disrupting STRA6 signaling. Suppression of STRA6 might be one novel pathogenesis of aorta in patients with MetS.

Abstract
OBJECTIVE Impaired baroreflex function is an early indicator of cardiovascular autonomic imbalance. Patients with type 2 diabetes mellitus (T2D) have decreased baroreflex sensitivity (BRS), however, whether the neural BRS (nBRS) and mechanical component of the BRS is altered in those with high metabolic risk (HMR, impaired fasting glucose and metabolic syndrome) or with overt T2D, is unknown. We examined this in a community-based observational study, the Paris Prospective Study III (PPS3). Approach and Results: In 7626 adults aged 50 to 75 years, resting nBRS (estimated by low-frequency gain, from carotid distension rate and RR [time elapsed between two successive R waves] intervals) and mechanical BRS were measured by high-precision carotid echotracking. The associations between overt T2D or HMR as compared with subjects with normal glucose metabolism and nBRS or mechanical BRS were quantified using multivariable linear regression analysis. There were 319 subjects with T2D (61±6 years, 77% male), 1450 subjects with HMR (60±6 years, 72% male), and 5857 subjects with normal glucose metabolism (59±6 years, 57% male). Compared with normal glucose metabolism, nBRS was significantly lower in HMR subjects (β=-0.07 [95% CI, -0.12 to -0.01]; P=0.029) and in subjects with T2D (β=-0.18 [95% CI, -0.29 to -0.07]; P=0.002) after adjustment for confounding and mediating factors. Subgroup analysis suggests significant and independent alteration in mechanical BRS only among HMR patients who had both impaired fasting glucose and metabolic syndrome. CONCLUSIONS In this community-based study of individuals aged 50 to 75, a graded decrease in nBRS was observed in HMR subjects and patients with overt T2D as compared with normal glucose metabolism subjects.

Five-year kidney outcomes of bariatric surgery differ in severely obese adolescents and adults with and without type 2 diabetes. Kidney Int 2020; 97:995-1005. [PMID: 32229096 DOI: 10.1016/j.kint.2020.01.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 12/09/2019] [Accepted: 01/02/2020] [Indexed: 12/17/2022]
Abstract
Bariatric surgery improves markers of kidney health in severe obesity, yet it is unclear if kidney disease outcomes differ according to age at surgery. Therefore, we examined health effects of Roux-en-Y gastric bypass between 161 adolescents and 396 adults participating in two related but distinct studies. Primary outcomes were elevated urine albumin-to-creatinine ratio (UACR) of 30 mg/g or more and hyperfiltration (an estimated glomerular filtration rate of 135 ml/min/1.73m2 or more). Analyses were stratified by the presence of pre-operative type 2 diabetes. Adolescents with pre-operative type 2 diabetes had a significantly increased prevalence of elevated UACR prior to surgery compared to adults (22.5 vs. 9.0%). Resolution of elevated UACR following surgery differed between adolescents and adults with type 2 diabetes, with adolescents experiencing a significantly earlier improvement following surgery. Adolescents without pre-operative type 2 diabetes demonstrated a significantly increased prevalence of UACR prior to surgery compared to adults (9.4 vs. 4.5%), with no improvement occurring in either group post-operatively. Adolescents with pre-operative type 2 diabetes had a significantly increased prevalence of hyperfiltration that remained throughout the study period, whereas hyperfiltration prevalence was similar among those without type 2 diabetes. Thus, adolescents with pre-operative type 2 diabetes experienced earlier attenuation of elevated UACR compared to adults with pre-operative type 2 diabetes in response to gastric bypass.

Abstract
Vascular dysfunction predisposes to cardiovascular complications of metabolic syndrome (MetS). The current study investigated the mechanism(s) of curcumin's (CUR) protective effect against vascular reactivity irregularities in MetS. MetS was induced by feeding rats on high fructose high salt diet. Tension studies were undertaken in aortic rings to assess the influence of CUR on vasoconstrictor or vasorelaxant responses. The effect on advanced glycation endproducts (AGEs) was studied by incubating aortic tissues with methylglyoxal, the AGEs precursor, in the absence and presence of CUR. In addition, CUR effects on in-vitro generation of AGEs and diphenyl-2-picrylhydrazyl (DPPH) free radicals were studied. The incubation with CUR for 1 hr produced significant and concentration-dependent alleviation of the exaggerated vasoconstriction observed in aortas isolated from MetS, however failed to improve the concomitant attenuation of vasodilatory responses to ACh in PE-precontracted aortas. By contrast, CUR caused direct concentration-dependent vasodilations of precontracted aortas, effects that were blunted after nitric oxide synthase inhibition by L-NAME. Similar to its effects in MetS aortas, CUR alleviated exaggerated PE vasoconstriction but did not affect impaired ACh vasodilations in AGEs-exposed aortas. In addition, CUR showed significant dose-dependent DPPH free radicals scavenging activity and inhibited both MG and fructose induced AGEs formation at the level of protein oxidation step as evident from the effect on dityrosine and N-formylkyramine. CUR alleviates exaggerated vasoconstriction in MetS through interfering with AGEs formation and AGEs-induced vascular injury. Free radical scavenging and direct vasodilatory activities could also participate in the advantageous vascular actions of CUR.

Abstract
Ageing is considered to be the major and non-modifiable risk factor for the development of hypertension and cardiovascular diseases. During ageing, the vascular system undergoes structural and functional alterations, including endothelial dysfunction, thickening of the vascular wall, reduced distensibility and increased arterial stiffness. Vascular rigidity results from fibrosis and remodelling of the extracellular matrix, processes that are associated with ageing and are amplified in hypertension. These events may be induced by vasoactive agents, such as angiotensin II, endothelin-1, and aldosterone, which are increased in the vasculature during aging and hypertension. Complex interaction between the process of ageing and prohypertensive factors results in accelerated vascular remodelling and fibrosis, as well as increased arterial stiffness. Hypertension accelerates and augments age-related vascular remodelling and dysfunction, and ageing may impact on the severity of vascular damage in hypertension, thus strongly suggesting close interactions between biological ageing and blood pressure elevation. Molecular and cellular mechanisms underlying vascular alterations in ageing and hypertension are common and include aberrant signal transduction, oxidative stress and activation of pro-inflammatory and pro-fibrotic transcription factors. Strategies to suppress age-associated vascular changes can ameliorate vascular damage associated with hypertension. This article looks into vascular alterations occurring during ageing and hypertension, focussing particularly on arterial stiffness and vascular remodelling, also emphasizing the importance of diagnostic methods.

Abstract
Contractile activity in the lymphatic vasculature is essential for maintaining fluid balance within organs and tissues. However, the mechanisms by which collecting lymphatics adapt to changes in fluid load and how these adaptations influence lymphatic contractile activity are unknown. Here we report a model of lymphatic injury based on the ligation of one of two parallel lymphatic vessels in the hind limb of sheep and the evaluation of structural and functional changes in the intact, remodelling lymphatic vessel over a 42-day period. We show that the remodelled lymphatic vessel displayed increasing intrinsic contractile frequency, force generation and vessel compliance, as well as decreasing flow-mediated contractile inhibition via the enzyme endothelial nitric oxide synthase. A computational model of a chain of lymphatic contractile segments incorporating these adaptations predicted increases in the flow-generation capacity of the remodelled vessel at the expense of normal mitochondrial function and elevated oxidative stress within the lymphatic muscle. Our findings may inform interventions for mitigating lymphatic muscle fatigue in patients with dysfunctional lymphatics.

Abstract
The aim of this study was to find a non-invasive pulse wave waveform index that was highly correlated with cardiovascular disease and to establish an effective model for cardiovascular health assessment in middle-aged men to provide early warning of possible cardiovascular and cerebrovascular diseases. Considering the characteristics of pulse wave easy to detect and rich physiological information, the paper collected pulse waves of healthy males at six age groups, and collected 50 samples per age group. The pulse wave waveform parameters of each sample were extracted, including inflow time, outflow time, total beat time, fast inflow time, inflow time ratio and waveform coefficient [Formula: see text] value, the differences of which in different age groups were analyzed. Stepwise regression analysis was used to establish the relationship between age and pulse waveform parameters. The results show that the indicators of inflow time, inflow time ratio and fast inflow time have obvious differences with age, and with the increase of age, these three indicators show a steady upward trend. The indicators of outflow time, total beat time, and waveform coefficient are not sensitive to age changes. A predictive model of vessel age was established: [Formula: see text] time ([Formula: see text]). The pulse wave inflow time of hypertensive patients was substituted into the above-mentioned model, and the calculated blood vessel age was greater than the actual age. The age difference is greater than 5 years old. This study suggests that the pulse wave parameters of inflow time, fast inflow time and inflow time ratio has a significant and stable trend with age, indicating that they are closely related to vascular elasticity, compliance and stiffness, and can be used as predictors of cardiovascular disease.

Abstract
Aim: Obesity and metabolic syndrome (MetS) frequently coexist and are both important risk factors for cardiovascular disease. However, the pathophysiological role of obesity without MetS, also referred to as metabolically healthy obesity (MHO), remains unclear. In this study, we aim to clarify the effect of MHO on the development of carotid plaque using a community-based cohort. Methods: We examined 1,241 subjects who underwent health checkups at our institute. Obesity was defined as body mass index of ≥ 25.0 kg/m2. Subjects were divided into three groups: non-obese, MHO, and metabolically unhealthy obesity (MUO). Results: The prevalence of carotid plaque, defined as intima-media thickness (IMT) ≥ 1.1 mm, was higher in subjects with MUO and MHO than in non-obese subjects. Multivariable analysis demonstrated that MHO (odds ratio 1.6, p = 0.012) and MUO (odds ratio 1.9, p = 0.003) as well as age of ≥ 65 years, male sex, hypertension, and diabetes mellitus were independently associated with carotid plaque formation. A similar trend was observed in each subgroup according to age and sex. Conclusions: MHO increased the prevalence of carotid plaque when compared with non-obese subjects, suggesting the potential significance of MHO in the development of subsequent cardiovascular diseases.

Abstract
Previous research suggests potential for fresh pears as a functional food for promoting cardiometabolic health. The purpose of this randomized, open-label, placebo-controlled, crossover clinical trial was to evaluate the influence of daily fresh pear consumption on blood pressure (primary outcome) and other biomarkers of cardiometabolic health in middle-aged/older adults with metabolic syndrome (MetS). Forty men and women aged 45-65 years with MetS were included and randomly assigned to receive either two medium-sized fresh pears (Pear) or a calorie-matched control drink (Control) per day for each 12-week treatment period, each separated by a 4-week washout period. After 12 weeks of daily fresh pear consumption, systolic blood pressure tended to be reduced (130 ± 2 mmHg vs. 134 ± 2 mmHg at baseline, P = 0.07) and pulse pressure was significantly reduced (51 ± 1 vs. 54 ± 1 at baseline, P < 0.05). At 12 weeks, leptin concentrations were lower in the Pear group than Control (52.5 [7.6, 120.5] ng dL-1vs. 53.4 [5.0, 120.5] ng dL-1, respectively, P < 0.05), and there was a significant group by time interaction (P < 0.05). Leptin concentrations were significantly reduced at 12 weeks compared to baseline in the Pear group (52.5 [7.6, 120.5] ng dL-1vs. 54.8 [6.4, 120.5] ng dL-1 at baseline, P < 0.05) but not in the Control group. Waist circumference was significantly reduced at 12 weeks in the Pear group (107.7 ± 2.0 cm vs. 108.4 ± 2 cm at baseline, P < 0.05) with a trend for a group by time interaction (P < 0.1), and significantly lower in the Pear group than Control (108.1 ± 2.0 cm vs. 108.8 ± 2 cm, P < 0.05) at 6 weeks with a significant group by time interaction (P < 0.05). Conversely, values were significantly increased at 6 weeks (108.8 ± 2 cm vs. 108.3 ± 2.0 cm at baseline, P < 0.05) in the Control group and sustained at 12 weeks. Waist-to-hip ratio was significantly reduced (0.92 ± 0.01 vs. 0.93 ± 0.01 at baseline, P < 0.05) at 12 weeks in the Pear group, and significantly lower than Control at 6 weeks (0.93 ± 0.01 vs. 0.93 ± 0.01, respectively, P < 0.05) and 12 weeks (0.92 ± 0.01 vs. 0.93 ± 0.01, P < 0.05). These findings suggest that daily fresh pear consumption may promote modest improvements in cardiometabolic health in middle-aged/older adults with MetS. This trial was registered at clinicaltrials.gov as NCT02228837.

Abstract
BACKGROUND Bariatric surgery results in weight loss and health improvements in adults and adolescents. However, whether outcomes differ according to the age of the patient at the time of surgery is unclear. METHODS We evaluated the health effects of Roux-en-Y gastric bypass in a cohort of adolescents (161 patients enrolled from 2006 through 2012) and a cohort of adults (396 patients enrolled from 2006 through 2009). The two cohorts were participants in two related but independent studies. Linear mixed and Poisson mixed models were used to compare outcomes with regard to weight and coexisting conditions between the cohorts 5 years after surgery. The rates of death and subsequent abdominal operations and selected micronutrient levels (up to 2 years after surgery) were also compared between the cohorts. RESULTS There was no significant difference in percent weight change between adolescents (-26%; 95% confidence interval [CI], -29 to -23) and adults (-29%; 95% CI, -31 to -27) 5 years after surgery (P = 0.08). After surgery, adolescents were significantly more likely than adults to have remission of type 2 diabetes (86% vs. 53%; risk ratio, 1.27; 95% CI, 1.03 to 1.57) and of hypertension (68% vs. 41%; risk ratio, 1.51; 95% CI, 1.21 to 1.88). Three adolescents (1.9%) and seven adults (1.8%) died in the 5 years after surgery. The rate of abdominal reoperations was significantly higher among adolescents than among adults (19 vs. 10 reoperations per 500 person-years, P = 0.003). More adolescents than adults had low ferritin levels (72 of 132 patients [48%] vs. 54 of 179 patients [29%], P = 0.004). CONCLUSIONS Adolescents and adults who underwent gastric bypass had marked weight loss that was similar in magnitude 5 years after surgery. Adolescents had remission of diabetes and hypertension more often than adults.

Abstract
BACKGROUND Hypertension in midlife has been associated with increased risk of stroke and neurocognitive decline. Few studies, however, have examined neurocognition among individuals with treatment-resistant hypertension or potential mechanisms by which treatment-resistant hypertension may impair neurocognition. METHODS We examined the pattern of neurocognitive impairment and potential mechanisms in a sample of 96 overweight adults with treatment-resistant hypertension, aged 41-81 years. Neurocognitive function was assessed using a 45-min test battery consisting of executive function and memory. Vascular and metabolic mechanisms examined included cerebrovascular risk factors (CVRFs: Framingham Stroke Risk Profile), insulin sensitivity (homeostatic model assessment of insulin resistance), waist-to-hip ratio, microvascular function (hyperemic response), and peak oxygen consumption from an exercise treadmill test. Simple path analyses were used to assess the association between potential vascular and metabolic mechanisms and neurocognition. RESULTS Neurocognitive impairments were common, with 70% of the sample exhibiting impaired performance on at least one executive function subtest and 38% on at least one measure of memory. Higher levels of aerobic fitness, greater insulin sensitivity, and better microvascular function, as well as lower CVRFs and waist-to-hip ratio were associated with better neurocognition. In path analyses, aerobic fitness, microvascular function, and CVRFs all were independently associated with neurocognitive performance. Insulin resistance associated with worse executive function but better memory performance among older participants. CONCLUSION Neurocognitive impairments are common in adults with treatment-resistant hypertension, particularly on tests of executive function. Better neurocognition is independently associated with aerobic fitness, microvascular function, and CVRFs.

Abstract
Introduction Low resting heart rate (RHR) and high cardiorespiratory fitness (VO2max) are associated with a reduction in cardiovascular events (CV). Carotid intima-media thickness (CIMT) has been suggested as a predictor of CV. The purpose of this study was to investigate the association between RHR, VO2max and CIMT. Methods The subjects of this study were 707 males aged 40–50 who visited the National Health Center of South Korea, a health examination institution, from 2010 to 2016. RHR was measured using electrocardiogram. RHR was divided into 4 levels (<60 beats per minute; bpm, 60–69 bpm, 70–79 bpm, ≥80 bpm). VO2max was measured by grade exercise test. Subject's VO2max was divided into 3 levels (first, second and third tertiles). CIMT was measured by B-mode ultrasound. Carotid atherosclerosis was defined as CIMT >1 mm. Results There was no significant difference in CIMT according to RHR level and there was no correlation between RHR and CIMT. High and middle VO2max group had significant lower CIMT than low VO2max group (P < 0.001). There was also a correlation between VO2max and CIMT (R = −0.129, P < 0.001). The low VO2max group showed 3.56-fold (95% CI, 1.77–7.16) higher relative risk of carotid atherosclerosis than the high VO2max group. Conclusion These results suggest that cardiovascular fitness index VO2max is associated to CIMT in middle-aged men. In addition, this study shows that VO2max are important indicators for the prevalence of carotid atherosclerosis.

Abstract
Insulin resistance is associated with subclinical vascular disease that is not justified by conventional cardiovascular risk factors, such as smoking or hypercholesterolemia. Vascular injury associated to insulin resistance involves functional and structural damage to the arterial wall that includes impaired vasodilation in response to chemical mediators, reduced distensibility of the arterial wall (arterial stiffness), vascular calcification, and increased thickness of the arterial wall. Vascular dysfunction associated to insulin resistance is present in asymptomatic subjects and predisposes to cardiovascular diseases, such as heart failure, ischemic heart disease, stroke, and peripheral vascular disease. Structural and functional vascular disease associated to insulin resistance is highly predictive of cardiovascular morbidity and mortality. Its pathogenic mechanisms remain undefined. Prospective studies have demonstrated that animal protein consumption increases the risk of developing cardiovascular disease and predisposes to type 2 diabetes (T2D) whereas vegetable protein intake has the opposite effect. Vascular disease linked to insulin resistance begins to occur early in life. Children and adolescents with insulin resistance show an injured arterial system compared with youth free of insulin resistance, suggesting that insulin resistance plays a crucial role in the development of initial vascular damage. Prevention of the vascular dysfunction related to insulin resistance should begin early in life. Before the clinical onset of T2D, asymptomatic subjects endure a long period of time characterized by insulin resistance. Latent vascular dysfunction begins to develop during this phase, so that patients with T2D are at increased cardiovascular risk long before the diagnosis of the disease.

Abstract
PURPOSE The objective of this study was to assess predictive value of various arterial markers for cardiovascular (CV) events in patients with metabolic syndrome (MetS). MATERIALS AND METHODS A longitudinal study with the follow-up period of 3.9 ± 1.7 years investigated 2728 middle-aged (53.9 ± 6.2 years old, 63% women) MetS subjects without overt CV disease. The study cohort was comprised of the participants of the Lithuanian High Cardiovascular Risk primary prevention program. The baseline assessment included the evaluation of brachial flow-mediated dilatation (FMD), carotid intima-media thickness (cIMT), carotid stiffness index, aortic pulse wave velocity (aPWV), aortic augmentation index (AIx), and cardio-ankle vascular index). The data on the cardiovascular outcome (fatal or non-fatal myocardial infarction or stroke) was collected by using the databases of the two major national registries. RESULTS Over the follow-up period, 83 (3%) patients had at least one cardiovascular event. In a univariate analysis, occurrence of CV events was associated with the following parameters: higher mean blood pressure, aPWV, AIx and cIMT, and lower FMD (all p < .05). In Cox proportional hazard regression analysis, the occurrence of CV event was associated with an increase in aPWV (HR 1.29, 95% CI 1.04-1.60, p = .019), AIx (HR 1.53, 95% CI 1.16-2.02, p = .003), and cIMT (HR 1.31, 95% CI 1.14-1.50, p < .001), and with the decrease in FMD (HR 0.83, 95% CI 0.71-0.97, p = .016) even after the adjustment for age, gender, and common cardiometabolic risk factors. In a two-level survival trees analysis, we established that patients with cIMT > 794 mcm had higher CV risk (p < .001) and their prognosis was further compromised by aPWV > 11.1 m/s (p = .023). Meanwhile, in patients with cIMT ≤ 794mcm, the FMD cut-off point of 6.5% further stratified the risk (p = .003). CONCLUSIONS In our prospective study, CV risk in the middle-aged patients with MetS was associated with an increase in cIMT and aPWV, and with a decrease in FMD.

Abstract
AIMS The metabolic syndrome (MetS) is composed of a cluster of related cardiovascular risk factors. The aim of the present study was to determine how MetS contributes to short- (30-day) and long-term complications and restenosis after carotid endarterectomy (CEA) or stenting (CAS). METHODS A consecutive cohort of 752 patients undergoing CEA (n = 314) and CAS (n = 438) in a single institution was examined, of which 296 (39.4%) were identified as having MetS. All patients were followed-up with carotid duplex ultrasound scan of the supraaortic vessels and a neurological assessment of symptoms status at 30-day postprocedure and at 3, 6, and 12 months, with annual follow-up thereafter for 3 years. RESULTS Patients with MetS had a significant increased risk in their 30-day death, major adverse events (MAE), and restenosis rates, both after CEA and after CAS (death: 0.7% vs 0.0%; MAE: 5.3% vs 2.7%; and restenosis: 1.7% vs 0.2%; p < 0.05). The MAE and restenosis rates remained statistically different at 36 months, with both procedures (29.2% vs 24.2% and 9.5% vs 3.3%, p < 0.05, for patients with and without MetS, respectively). Among the components of MetS, high fasting serum glucose, low high-density lipoprotein cholesterol, and elevated body mass index were associated with increased risk of complications at 30 days and within 36 months. CONCLUSIONS The current study suggested that the presence of MetS is an important risk factor for morbidity and restenosis after CEA and CAS.

Abstract
Background: Cognitive reserve is a way of explaining why some individuals with a high degree of brain pathology are without clinical manifestations. In this study, factors related to systemic diseases, body composition, aerobic capacity, past and current behavior were examined and included as predictors of cognitive function. Materials and Methods: 407 subjects (60–88 years old) underwent physical examination and cognitive function assessment [Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Trail Making Test Part B (TMT B)]. Predictors of cognitive functioning were evaluated: occupational status (OS), diet, mental and touristic activities were assessed using an ad hoc questionnaire. Aerobic capacity was measured using a six-minute walk test (6MWT). Results: With each year of age there is a decrease in MMSE score by 0.18 points. Varicose veins on lower extremities and low OS were also significantly associated with MMSE result. For every year of having hypertension, low OS and not being abroad in the last 3 years, there was 0.17, 0.30, and 0.16 less points, respectively, and 0.15 more point per one additional meter walked in 6MWT in the MoCA score. With each year of age and for low OS there was there were 0.31 and 0.21 s more to complete TMT B, respectively. Conclusion: Education, OS, presence of systemic diseases and social and tourist activities, aerobic capacity and body composition could be considered as factors contributing to cognitive functioning in older people. However, the relationship of above mentioned factors with education level and cognitive function may be not fully orthogonal.

Abstract
Background: Extracellular vesicles (EVs) released from mesenchymal stem/stromal cells (MSCs) mediate their paracrine effect, but their efficacy to protect the microcirculation of the kidney is unknown. Using a novel swine model of unilateral renovascular disease (RVD) complicated by metabolic syndrome (MetS), we tested the hypothesis that EVs would attenuate renal microvascular loss. Methods: Four groups of pigs (n = 7 each) were studied after 16 weeks of diet-induced MetS and RVD (MetS+RVD), MetS+RVD treated 4 weeks earlier with a single intra-renal delivery of EVs harvested from autologous adipose tissue-derived MSCs, and Lean and MetS Sham controls. Stenotic-kidney renal blood flow (RBF) and glomerular filtration rate (GFR) were measured in-vivo (fast CT), whereas EV characteristics, renal microvascular architecture (micro-CT), and injury pathways were studied ex-vivo. Results: mRNA sequencing and proteomic analysis revealed that EVs are packed with several pro-angiogenic genes and proteins, such as vascular endothelial growth factor. Labeled EVs were detected in the stenotic kidney 4 weeks after injection internalized by tubular and endothelial cells. EVs restored renal expression of angiogenic factors and improved cortical microvascular and peritubular capillary density. Renal apoptosis, oxidative stress, tubular injury, and fibrosis were also attenuated in EV-treated pigs. RBF and GFR decreased in MetS+RVD compared with MetS, but normalized in MetS+RVD+EVs. Conclusions: Intra-renal delivery of MSC-derived EVs bearing pro-angiogenic properties restored the renal microcirculation and in turn hemodynamics and function in chronic experimental MetS+RVD. Our study suggests a novel therapeutic potential for MSC-derived EVs in restoring renal hemodynamics in experimental MetS+RVD.

Systemic inflammation as a predictor of brain aging: Contributions of physical activity, metabolic risk, and genetic risk. Neuroimage 2018; 172:118-129.

Abstract
Inflammatory processes may contribute to risk for Alzheimer's disease (AD) and age-related brain degeneration. Metabolic and genetic risk factors, and physical activity may, in turn, influence these inflammatory processes. Some of these risk factors are modifiable, and interact with each other. Understanding how these processes together relate to brain aging will help to inform future interventions to treat or prevent cognitive decline. We used brain magnetic resonance imaging (MRI) to scan 335 older adult humans (mean age 77.3 ± 3.4 years) who remained non-demented for the duration of the 9-year longitudinal study. We used structural equation modeling (SEM) in a subset of 226 adults to evaluate whether measures of baseline peripheral inflammation (serum C-reactive protein levels; CRP), mediated the baseline contributions of genetic and metabolic risk, and physical activity, to regional cortical thickness in AD-relevant brain regions at study year 9. We found that both baseline metabolic risk and AD risk variant apolipoprotein E ε4 (APOE4), modulated baseline serum CRP. Higher baseline CRP levels, in turn, predicted thinner regional cortex at year 9, and mediated an effect between higher metabolic risk and thinner cortex in those regions. A higher polygenic risk score composed of variants in immune-associated AD risk genes (other than APOE) was associated with thinner regional cortex. However, CRP levels did not mediate this effect, suggesting that other mechanisms may be responsible for the elevated AD risk. We found interactions between genetic and environmental factors and structural brain health. Our findings support the role of metabolic risk and peripheral inflammation in age-related brain decline.

Early Regression of Carotid Intima-Media Thickness after Bariatric Surgery and Its Relation to Serum Leptin Reduction. Obes Surg 2018; 28:226-233.

Abstract
PURPOSE Bariatric surgery (BS) promotes carotid intima-media thickness (C-IMT) regression as early as 6 months post-surgery. To verify whether C-IMT regression occurs even earlier, we aimed at the effect of Roux-en-Y gastric bypass (RYGBP) and biliopancreatic diversion (BPD) on C-IMT 1-2 months and 12 months post-surgery. SUBJECTS/METHODS Prospective trial. BS was performed on 109 patients either with (RYGBP = 42; BDP = 40) or without type 2 diabetes (RYGBP = 27). Healthy volunteers served as control group. FOLLOW-UP baseline, 1-2 months, 12 months post-surgery. ENDPOINTS changes (∆) in C-IMT, weight, body mass index, fat mass, waist and neck circumferences, blood pressure, HbA1c, glucose, insulin, insulin sensitivity [HOMA-IR; OGIS, from meal tolerance test], lipids, C-reactive protein, leptin, adiponectin, MCP-1. RESULTS All surgery subgroups had similar levels of ∆-C-IMT. C-IMT in the pooled surgery group reduced from [mean (95% confidence interval)] 0.81 (0.77-0.84) mm to 0.66 (0.63-0.69) mm, p < 0.001 [-17.1 (-20.4 to -13.8)%] at 1-2 months, and to 0.63 (0.59-0.66) mm, p < 0.001 [-21.8 (-25.3 to -18.4)%] at 12 months post-surgery. ∆-C-IMT 1-2 months and 12 months post-surgery correlated to baseline C-IMT, and with ∆-leptin at 1-2 months, but not at 12 months post-surgery. In linear regression analysis, ∆-leptin and baseline C-IMT were predictors of ∆-C-IMT 1-2 months post-surgery. CONCLUSIONS A remarkable C-IMT regression occurred as early as 1-2 months after BS in obese patients either with or without type 2 diabetes, which was associated to the early reduction in leptin, (at least partially) independent of weight loss. Whether this is a causative or correlative association needs further investigation.
