Abstract
BACKGROUND Vascular comorbidities are prevalent in persons with multiple sclerosis (MS), yet less is known about underlying vascular function (VF). We performed a systematic review with meta-analysis of studies that compared VF in persons with MS and healthy controls and examined factors that may moderate the difference in vascular outcomes between groups. METHODS We conducted a systematic search using PubMed/MEDLINE, CINAHL, and Embase from inception through March 2024. The search identified studies that included comparisons of VF between MS and controls on a range of function and structure outcomes (e.g., pulse wave velocity, augmentation index, arterial diameter, intima-media thickness, flow-mediated dilation). Effect sizes were calculated as standardized mean differences (SMD) using Hedge's g with a positive effect indicating worse VF in MS than controls. The meta-analysis involved a multilevel random effects model with follow-up moderator analyses. RESULTS Fourteen studies met the inclusion criteria and yielded 49 effect sizes for meta-analysis. The MS subjects (N = 614) were predominantly female (72.0 %), with mean ages ranging from 29.9 to 54.4 years. There was a moderate difference in VF between persons with MS and healthy controls (SMD [95 % CI] = 0.56 [0.08, 1.03]; p = 0.02), and the effects were heterogenous (Q48=634.5, p < 0.01; I2=94.39 %). There was a greater difference in arterial stiffness between MS and controls (0.78 [0.21, 1.36], p = 0.008), but not in other arterial structure or function outcomes (p > 0.05). No significant moderators were detected (p > 0.05). CONCLUSIONS The cumulative evidence supports that persons with MS have worse VF, notably greater arterial stiffness, than healthy controls. Such findings support future research on the cause, consequences, and management of arterial stiffness among persons with MS.

Abstract
OBJECTIVE The aim of this study is to investigate whether there is a relationship between age or sex and the thickness of the radial artery wall. MATERIALS AND METHODS We harvested human radial arteries from 48 cadavers (30 men and 18 women) in the anatomy laboratory. Histological sections of 3 μm thickness were prepared at the Laboratory of Anatomy and Pathological Cytology, mounted on slides, and stained with hematoxylin-phloxine-safran, Masson's trichrome, and orcein. The thickness of each radial artery wall (intima-media thickness) was measured using optical microscopy, and an average measurement was established among the three thicknesses (upper third, middle third, and lower third). STATISTICAL METHODS Statistical analyses were performed using the R software. Means and standard deviations were utilized. A correlation analysis was also conducted to assess the relationship between radial artery wall thickness and subjects' age. RESULTS On average, the thickness of the left radial artery wall and that of the right radial artery measured 282 (34) micrometers (μm). We found a correlation between radial artery wall thickness and age in both men (p < 0.001) and women (p < 0.001). CONCLUSIONS In conclusion, this study elucidates that radial artery wall thickness is related to age and sex in its assessment.

Abstract
Purpose Arterial stiffness is often increased in overweight or obese individuals before the development of hypertension (HT). This study aimed to determine the connection between pancreatic fat and atherosclerosis in overweight and obese people without HT. Patients and methods We included 128 patients who were non-hypertensive and overweight or obese in a study between December 2019 and November 2022. Medical history was collected, and all participants underwent a physical examination and blood tests. Pancreatic fat content was measured by magnetic resonance imaging (MRI) and was grouped into quartiles based on pancreatic fat fraction (PFF). The upper three quartiles (PFF≥10.33%) were defined as non-alcoholic fatty pancreas disease (NAFPD) and the first quartile (PFF<10.33%) as non-NAFPD. High baPWV (H-baPWV) and low baPWV (L-baPWV) were classified according to the median baPWV (1159 cm/s). The effect of NAFPD on baPWV was examined using binary logistic regression. The study population consisted of 96 NAFPD and 32 non-NAFPD cases. Results Participants with NAFPD had significantly higher levels of baPWV than people without. The rates of NAFPD and the PFF values varied significantly in the L-baPWV and H-baPWV groups. Logistic regression analysis suggested that the presence of NAFPD was independently correlated with increased baPWV after adjusting for age, smoking, body mass index, blood pressure, lipid profiles, and glycemic index. Conclusion NAFPD is an independent risk factor for increased baPWV in individuals with overweight and obesity but no HT, suggesting that the presence of NAFPD may be a warning signal of early atherosclerosis.

Abstract
This study aimed to identify the relationship between exercise-induced hypertension and carotid artery intima-media thickness in long-distance runners. Sixty healthy male runners aged 40 to 60 years were assigned to the following three groups based on resting blood pressure and maximal systolic blood pressure during a maximal exercise test: normal blood pressure response, exercise-induced hypertension, and complex hypertension. An exaggerated systolic blood pressure response was defined as a maximal systolic blood pressure+≥+210 mmHg during the maximal exercise test, while carotid intima-media thickness was measured using B-mode ultrasonography. The carotid intima-media thickness mean values were the highest in the complex hypertension group (0.72±0.11 mm), followed by exercise-induced hypertension (0.62±0.12 mm) and normal blood pressure groups (0.55±0.13 mm), with a significant difference between the groups (p+<+0.002). In linear regression analysis, the mean intima-media thickness was independently associated with age (p=0.015) and maximal systolic blood pressure (p=0.046) but not with resting systolic blood pressure. These results suggest that exercise-induced hypertension is associated with carotid intima-media thickness, a surrogate marker of cardiovascular disease, in long-distance runners. Therefore, evaluating the blood pressure response during exercise is important for the early detection of potential cardiovascular disease risks in long-distance runners.

Abstract
BACKGROUND Hemodialysis (HD) patients present an increased carotid intima-media thickness (CIMT) and calcified plaques, and studies have demonstrated that CIMT is predictor for cardiovascular death in this patient population; hence, the importance of identifying early non-invasive markers of atherosclerosis. We aim to propose a new three-perspective CIMT measuring method in HD population, and to further investigate the possible use and value of this method to predict outcomes. METHODS A cross-sectional study was conducted, the CIMT was measured with duplex ultrasound during the perioperative access planning. Software provided maximum CIMT in a 10 mm (mm) width of the common carotid artery. CIMT was measured in Right (R) and Left (L) carotid arteries, both in anterior (a), lateral (l), and posterior (p) view. The sum of these values (Ra+Rl+Rp+La+Ll+Lp) was completed and termed as Sixth Carotid Intimal (SCI) score. We stratified either in low (summation <4) or high (>=4) SCI score groups. Demographics, patency rates, complications, and mortality were collected; chi-square test was used for our analysis. RESULTS A total of 30 patients (mean age 49 years and 56% females) that underwent access creation in the upper arm from 2010 to 2016 were selected and studied. A low SCI score was found 19 patients and 11 had high SCI, no significant difference was observed in demographics, history cardiovascular disease, and clinical outcomes as early thrombosis, and primary, primary-assisted patency at 12 months. Interestingly, during the follow up period of 36 months a significant higher difference in late thrombosis rates occurred (63.6% vs 26.3%, p = .044) and a higher all-cause mortality (54.4% vs 15.7%, p = .025) in patients with SCI score group above 4. CONCLUSIONS The SCI score method, might offer a screening tool for traditional cardiovascular risk factors in HD patients. In this study, we demonstrate an increased rate in late thrombosis and mortality in those with high SCI. Further research is necessary to better define the role of CIMT in vascular surgical procedures.

Abstract
Glioblastoma is the most fatal and insidious malignancy, due to the existence of the blood-brain barrier (BBB) and the high invasiveness of tumor cells. Abnormal mitochondrial viscosity has been identified as a key feature of malignancies. Therefore, this study reports on a novel fluorescent probe for mitochondrial viscosity, called ZVGQ, which is based on the twisted intramolecular charge transfer (TICT) effect. The probe uses 3-dicyanomethyl-1,5,5-trimethylcyclohexene as an electron donor moiety and molecular rotor, and triphenylphosphine (TPP) cation as an electron acceptor and mitochondrial targeting group. ZVGQ is highly selective, pH and time stable, and exhibits rapid viscosity responsiveness. In vitro experiments showed that ZVGQ could rapidly recognize to detect the changes in mitochondrial viscosity induced by nystatin and rotenone in U87MG cells and enable long-term imaging for up to 12 h in live U87MG cells. Additionally, in vitro 3D tumor spheres and in vivo orthotopic tumor-bearing models demonstrated that the probe ZVGQ exhibited exceptional tissue penetration depth and the ability to penetrate the BBB. The probe ZVGQ not only successfully visualizes abnormal mitochondrial viscosity changes, but also provides a practical and feasible tool for real-time imaging and clinical diagnosis of glioblastoma.

Abstract
Ambient fine particulate matter (PM2.5) is a leading environmental risk factor globally, and over half of the associated disease burden are caused by cardiovascular disease. Numerous randomized controlled trials (RCT) have investigated the short-term cardiovascular benefits of indoor air purifiers (IAPs), but major knowledge gaps remain on their longer-term benefits. In this 1-year, randomized, double-blinded, parallel controlled trial of 47 elderly (ntrue-purification = 24; nsham-purification = 23) aged ≥70 years, true-purification reduced household PM2.5 levels by 28% and maintained lower exposure throughout the year compared to the sham-purification group. After 12 months of intervention, a significant reduction of diastolic blood pressure was found in the true-purification versus sham-purification group (-4.62 [95% CI: -7.28, -1.96] mmHg) compared to baseline measurement prior to the intervention, whereas systolic blood pressure showed directionally consistent but statistically non-significant effect (-2.49 [95% CI: -9.25, 4.28] mmHg). Qualitatively similar patterns of associations were observed for pulse pressure (-2.30 [95% CI: -6.57, 1.96] mmHg) and carotid intima-media thickness (-10.0% [95% CI: -24.8%, 4.7%]), but these were not statistically significant. Overall, we found suggestive evidence of cardiovascular benefits of long-term IAPs use, particularly on diastolic blood pressure. Evidence on other longer-term cardiovascular traits is less clear. Further trials with larger sample sizes and long-term follow-up are needed across diverse populations to evaluate the cardiovascular benefits of IAPs.

Abstract
BACKGROUND Atherosclerotic changes can be attributed to early endothelial damage in individuals with hypertension. We aimed to explore the relationship between endothelial dysfunction and hypertension in newly diagnosed children without end-organ damage, considering carotid intima-media thickness (CIMT), flow-mediated dilatation (FMD), and functional capillaroscopy parameters. We also analyzed the differences between dipper and non-dipper patients. METHODS In this cross-sectional study, 20 patients diagnosed with essential hypertension with no target organ damage, and 20 age and sex-matched healthy volunteers were enrolled. The patient group comprised newly diagnosed individuals not receiving antihypertensive treatment. Hypertensive patients were divided into two groups (dipper and non-dipper patients). The measurements of CIMT, brachial FMD, and functional capillaroscopy were performed before starting treatment. RESULTS Among the patients, 11 were boys, and 9 were girls, with a median age of 16.0 (2.13) years. Of 20 hypertensive patients, 10 were dipper and 10 were non-dipper. Significant differences were observed between the hypertensive patients and controls in terms of CIMT (p = 0.04), brachial artery FMD (p = 0.02), and functional capillary density (p < 0.001). Hypertensive patients exhibited increased CIMT, reduced brachial artery FMD, and lower capillary density. However, there were no differences between dippers and non-dippers regarding age, sex, height SDS, weight SDS, CIMT SDS, brachial artery FMD, and capillary density. CONCLUSIONS Understanding the vascular consequences associated with essential hypertension emphasizes the importance of early detection and management of hypertension. Herein, we have effectively highlighted significant endothelial changes through the analysis of three parameters in newly diagnosed children without apparent target organ damage.

Abstract
Metabolic syndrome comprises a set of risk factors that include abdominal obesity, impaired glucose tolerance, hypertriglyceridemia, low high-density lipoprotein levels, and high blood pressure, at least three of which must be fulfilled for diagnosis. Metabolic syndrome has been linked to an increased risk of cardiovascular disease and type 2 diabetes mellitus. Multimodality imaging plays an important role in metabolic syndrome, including diagnosis, risk stratification, and assessment of complications. CT and MRI are the primary tools for quantification of excess fat, including subcutaneous and visceral adipose tissue, as well as fat around organs, which are associated with increased cardiovascular risk. PET has been shown to detect signs of insulin resistance and may detect ectopic sites of brown fat. Cardiovascular disease is an important complication of metabolic syndrome, resulting in subclinical or symptomatic coronary artery disease, alterations in cardiac structure and function with potential progression to heart failure, and systemic vascular disease. CT angiography provides comprehensive evaluation of the coronary and systemic arteries, while cardiac MRI assesses cardiac structure, function, myocardial ischemia, and infarction. Liver damage results from a spectrum of nonalcoholic fatty liver disease ranging from steatosis to fibrosis and possible cirrhosis. US, CT, and MRI are useful in assessing steatosis and can be performed to detect and grade hepatic fibrosis, particularly using elastography techniques. Metabolic syndrome also has deleterious effects on the pancreas, kidney, gastrointestinal tract, and ovaries, including increased risk for several malignancies. Metabolic syndrome is associated with cerebral infarcts, best evaluated with MRI, and has been linked with cognitive decline. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Common carotid artery diameter and the risk of cardiovascular disease mortality: a prospective cohort study in northeast China. BMC Public Health 2024; 24:251. [PMID: 38254061 PMCID: PMC10801967 DOI: 10.1186/s12889-024-17749-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 01/11/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND The association between the common carotid artery (CCA) diameter and cardiovascular disease (CVD) is recognized, but the precise nature of this link remains elusive. This study aimed to investigate the potential relationship between CCA diameter and the risk of CVD mortality in a large population in northeast China. METHODS The current study included 5668 participants (mean age 58.9 ± 10.1 years) from a population-based study conducted in rural areas of northeast China between September 2017 and May 2018. Information on death was collected from baseline until July 31, 2022. The CCA inter-adventitial diameter was measured using ultrasound. Cox proportional-hazard models were employed to explore the relationship between the common carotid artery diameter and cardiovascular mortality. RESULTS At baseline, the mean CCA diameter (mm) of subjects was 7.30 ± 0.99 and increased significantly with age, ranging from 6.65 ± 0.71 among people 40-49 years to 7.99 ± 1.04 among people ≥ 80 years. CCA diameter was significantly larger in males compared to females (7.51 ± 1.03 versus vs. 7.16 ± 0.94; P < 0.001). A total of 185 participants died of CVD during a median follow-up of 4.48 years. CCA diameters were divided into quartiles, and the highest quartile of carotid diameter (≥ 8.06 mm) had a 2.29 (95% confidence interval [CI]: 1.24, 4.22) times higher risk of CVD mortality than the lowest quartile (≤ 6.65 mm) (P < 0.01) in the fully adjusted model. Each increase in the diameter of the common carotid artery (per SD) raised the risk of cardiovascular death by 36% (hazard ratio [HR]: 1.36; 95% CI: 1.18, 1.57). The subgroup analysis results demonstrated that a per SD increase was associated with a 42% increased risk of CVD mortality in participants aged ≥ 64 years in the fully adjusted model (HR: 1.42; 95%CI: 1.21, 1.66). CONCLUSIONS Our study indicates the possible incremental value of CCA diameter in optimizing the risk stratification of cardiovascular disease and provides essential insights into reducing the burden of cardiovascular disease.

Abstract
BACKGROUND Carotid intima-media thickness (cIMT) has been widely used as a predictor of future cardiovascular disease (CVD); however, various definitions of cIMT exist. This study provides a systematic review and meta-analysis of the associations between different cIMT definitions and CVD. METHODS AND RESULTS A systematic review of the different cIMT definitions used in prospective cohort studies was performed. The relationships between cIMT of different definitions (common carotid artery IMT [CCA-IMT], internal carotid artery IMT [ICA-IMT], combined segments [combined-IMT], mean CCA-IMT, and maximum CCA-IMT) with future stroke, myocardial infarction (MI), and CVD events were analyzed using random effects models. Among 2287 articles, 18 articles (14 studies) with >10 different cIMT definitions were identified and included in our meta-analysis. After adjusting for age and sex, a 1-SD increase in CCA-IMT was associated with future stroke (hazard ratio [HR], 1.32 [95% CI, 1.27-1.38]), MI (HR, 1.27 [95% CI, 1.22-1.33]), and CVD events (HR, 1.28 [95% CI, 1.19-1.37]). A 1-SD increase in ICA-IMT was related to future stroke (HR, 1.25 [95% CI, 1.11-1.42]) and CVD events (HR, 1.25 [95% CI, 1.04-1.50]) but not MI (HR, 1.26 [95% CI, 0.98-1.61]). A 1-SD increase in combined-IMT was associated with future stroke (HR, 1.30 [95% CI, 1.08-1.57]) and CVD events (HR, 1.36 [95% CI, 1.23-1.49]). Maximum CCA-IMT was more strongly related than mean CCA-IMT with risk of MI, and both measures were similarly associated with stroke and CVD events. CONCLUSIONS Combined-IMT is more strongly associated with CVD events compared with single-segment cIMT definitions. Maximum CCA-IMT shows a stronger association with MI than mean CCA-IMT. Further research is warranted to validate our findings and to standardize the cIMT measurement protocol, as well as to explore underlying mechanisms.

Abstract
BACKGROUND Psoriasis is a protean disease associated with several comorbidities that may have increased levels of adiponectin such as resistin. This may affect the patients atherosclerotic risk. OBJECTIVE To study resistin levels in a sample of Brazilian patients with psoriasis and its association with clinical profile, comorbidities, and carotid Intima-Media Thickness (cIMT). METHODS This is a cross-sectional study of 119 individuals: 34 healthy controls and 85 patients with psoriasis, 42 of which with skin involvement only and 43 with psoriatic arthritis. Clinical and epidemiological data, measurement of PASI (Psoriasis Area Severity Index) and DAPSA (Disease Activity in Psoriatic Arthritis), lipid profile, cIMT by ultrasound were collected from medical records. Resistin serum levels were measured by ELISA. RESULTS Patients with psoriasis had higher resistin levels (p=0.009) and worse cIMT (p=0.0002) than controls. In the psoriasis sample, no associations of resistin levels with epidemiological, clinical findings, and activity indexes were found. Resistin serum levels were associated with the presence of diabetes (p=0.008) and metabolic syndrome (p=0.01) and correlated with total cholesterol (r=0.26) and triglycerides (r=0.33) but not with cIMT. STUDY LIMITATIONS This work is limited by its transversal design and by the limited number of patients included. CONCLUSION Resistin serum levels are elevated in psoriasis patients. In this sample, clinical, epidemiological, and activity indexes were not linked to resistin serum levels, but atherosclerotic risk factors were.

Abstract
Mitochondrial viscosity is closely associated with intracellular physiological activities yet their abnormality will result in various diseases. In particular, viscosity in cancer cells is different from that in normal cells, which is thought to be an indicator for cancer diagnosis. However, there were few fluorescent probes able to distinguish homologous cancer and normal cells by detecting mitochondrial viscosity. Herein, we designed a viscosity-sensitive fluorescent probe (named NP) based on the twisting intramolecular charge transfer (TICT) mechanism. NP exhibited exquisite sensitivity to viscosity and selectivity to mitochondria and excellent photophysical properties, such as large Stokes shift and high molar extinction coefficient, which enables wash-free, high-fidelity and fast imaging mitochondria. Moreover, it was capable of detecting mitochondrial viscosity in living cells and tissue, as well as monitoring apoptosis process. Significantly, considering numerous breast cancer cases in every country of the world, NP was successfully applied to distinguish human breast cancer cells (MCF-7) from normal cells (MCF-10A) by difference in fluorescence intensity originated from abnormality in mitochondrial viscosity. All the results indicated that NP could serve as a robust tool for effectively detecting mitochondrial viscosity changes in-situ.

Abstract
OBJECTIVE To determine whether patients with drug-resistant mesial temporal lobe epilepsy present with an alteration in the autonomic circadian regulation of blood pressure. METHODS A prospective case‒control study was designed, with a case group comprising patients with drug-resistant mesial temporal lobe epilepsy and a control group comprising healthy volunteers. Twenty-four-hour outpatient blood pressure monitoring was performed to assess the existence of a normal (dipping) or altered (non-dipping) circadian pattern. In addition, analytical and ultrasound parameters (carotid intima-media thickness) of vascular risk and sleep quality were evaluated. RESULTS Twenty-four subjects were recruited in each study group, amongst whom no demographic differences or history of vascular risk were observed. A higher percentage of participants with a non-dipping pattern was observed in the group of patients with epilepsy (62.5% vs. 12.5, p = 0.001). In the case group, significant differences were also observed in carotid intima-media thickness, with a greater probability of presenting with pathological values (p = 0.022). CONCLUSION The results suggest a disorder of the central autonomic control of blood pressure in patients with drug-resistant mesial temporal lobe epilepsy, with a greater probability of developing an alteration of the circadian rhythm of blood pressure. This dysfunction may be a factor involved in the increased cardiovascular risk in this population.

Abstract
Pre-obesity is a condition that predisposes to the risk of developing obesity, cardiovascular diseases (CVD), and diabetes. Our previous study demonstrated that a Cynara cardunculus (L.) based nutraceutical named Altilix® (Bionap, Italy), containing chlorogenic acid and luteolin extracts, was able to improve several hepatic and cardio-metabolic parameters. Given this background, we conducted a post-hoc analysis of the Altilix® study in order to analyze the supplement’s effects in the subgroup of pre-obesity subjects on anthropometry (weight and waist circumference), glucose metabolism (HbA1C, HOMA-IR, and HOMA-β), lipid profile (total cholesterol, triglycerides, LDL-cholesterol and HDL-cholesterol), hepatic functionality (FLI, AST, ALT and AST/ALT), carotid-media thickness (CIMT) and endothelial function (FMD). Fifty subjects from the original study cohort (which consisted of 100 subjects) were chosen with BMI ≥ 25 and < 30 kg/m2. All subjects received the Altilix® supplement (150 mg/day) or placebo using a computer-based random allocation system. After six months of treatment Altilix® significantly reduced body weight, glycemic, and lipid parameters (total cholesterol, triglycerides, LDL-cholesterol) and improved hepatic functionality, CIMT, and FMD. In conclusion, these results confirm that Altilix® supplementation has a significant effect on cardiometabolic parameters not only in obese subjects but also in pre-obesity subjects.

Abstract
Background
The noncoding antisense transcript for β-secretase-1 (
BACE1-AS
) is a long noncoding RNA with a pivotal role in the regulation of amyloid-β (Aβ). We aimed to explore the clinical value of
BACE1-AS
expression in atherosclerotic cardiovascular disease (ASCVD).
Methods
Expression of
BACE1-AS
and its target, β-secretase 1 (
BACE1
) mRNA, was measured in peripheral blood mononuclear cells derived from 434 individuals (259 without established ASCVD [non-CVD], 90 with stable coronary artery disease [CAD], and 85 with acute coronary syndrome). Intima-media thickness and atheromatous plaques evaluated by ultrasonography, as well as arterial wave reflections and pulse wave velocity, were measured as markers of subclinical ASCVD. Patients were followed for a median of 52 months for major adverse cardiovascular events (MACE).
Results
In the cross-sectional arm,
BACE1-AS
expression correlated with
BACE1
expression (
r
= 0.396,
p
< 0.001) and marginally with Aβ1–40 levels in plasma (
r
= 0.141,
p
= 0.008). Higher
BACE1-AS
was associated with higher estimated CVD risk assessed by HeartScore for non-CVD subjects and by European Society of Cardiology clinical criteria for the total population (
p
< 0.05 for both).
BACE1-AS
was associated with higher prevalence of CAD (odds ratio [OR] = 1.85, 95% confidence interval [CI]: 1.37–2.5), multivessel CAD (OR = 1.36, 95% CI: 1.06–1.75), and with higher number of diseased vascular beds (OR = 1.31, 95% CI: 1.07–1.61, for multiple diseased vascular beds) after multivariable adjustment for traditional cardiovascular risk factors. In the prospective arm,
BACE1-AS
was an independent predictor of MACE in high cardiovascular risk patients (adjusted hazard ratio = 1.86 per ascending tertile, 95% CI: 1.011–3.43,
p
= 0.046).
Conclusion
BACE1-AS
is associated with the incidence and severity of ASCVD.

Vasc Health Risk Manag 2022; 18:453-461. [PMID: 35800291 PMCID: PMC9255902 DOI: 10.2147/vhrm.s366339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 06/13/2022] [Indexed: 11/23/2022] Open
Abstract
Background Several classic/traditional risk factors are associated with intima–media thickness (IMT), a novel risk of cardio metabolic risk (CMR) in the literature but not in Kinshasa, a megacity prone to CMR. Thus, the objective of this study was to evaluate potential correlations between inflammation, kidney function, psychological stress, hemodynamics, and changes in IMT. Methods This cross-sectional study was carried out between 2018 and 2021 within Monkole and Biamba Marie Mutombo Hospitals, respectively, and randomly selected from 10 health structures from East and West of Kinshasa, Capital of Democratic Republic Congo (DRC). A random sample of adult hypertensive Bantu Central Africans was examined after bivariate correlations and multiple linear regression. Results Out of 280 patients with 140 men and 140 women aged 62 ± 11 years, the mean carotid intima–media thickness (CIMT) was 1.06 ± 0.5 mm and 73% (n = 204) patients had uncontrolled hypertension. After controlling for confounders, 52.9% variations (R2) of CIMT were independently and significantly (P = 0.037) predicted by CRP, 24-hour proteinuria, urinary albumin/creatinine ratio, duration of hypertension, heart rate, hip circumference, and psychological stress with Equation Y = 0.717 + 0.87 × CRP + 0.02 × 24 H – proteinuria + 0.005 × urinary albumin/creatinine ratio + 0.05 × duration of hypertension + 0.001 × heart rate + 0.006 × hip circumference + 0.017 × psychological stress. Conclusion There is an urgent need to control inflammation, impaired renal function, cardiac rhythm, peripheral obesity, longer duration of hypertension management, and stress, which are emerging as specific novel determinants of the subclinical atherosclerosis for those Bantu Central African hypertensive patients.

Abstract
AIMS Cardiovascular disease (CVD) is the leading cause of mortality in type 2 diabetes mellitus (T2DM). Epidemiological studies suggest serum Osteoprotegrin (OPG)/Tumour-necrosis-factor-related-apoptosis-inducing- ligand (TRAIL) ratio may be a useful marker of cardiovascular risk. This study aimed to compare serum levels of TRAIL, OPG and OPG/TRAIL ratio in people with T2DM, with and without a history of CVD, and controls; and to determine which of these indices, if any, predict cardiovascular risk. METHODS In this single centre observational study of 133 participants, people with T2DM, with and without a history of a cardiovascular event in the last 5 years, were recruited along with a control cohort without T2DM or CVD. Demographic information and anthropometric measurements were recorded. Blood samples were taken and OPG and TRAIL were measured using ELISA. RESULTS People with T2DM and CVD had higher OPG/TRAIL ratios compared to controls or those with a new diagnosis of T2DM. After adjustment for potential confounding factors, OPG/TRAIL ratio was significantly associated with the presence of CVD in people with T2DM and an OPG/TRAIL ratio cut-off > 38.6 predicted the presence of CVD in this cohort with a sensitivity of 80% and specificity of 82%. CONCLUSION This study suggests that OPG/TRAIL ratio may have a role as a biomarker of CVD in people with T2DM.

Abstract
Microviscosity is a fundamental parameter in the biophysics of life science and governs numerous cellular processes. Thus, the development of real-time quantitative monitoring of microviscosity inside cells is important. The traditional probes for detecting microviscosity via time-resolved luminescence imaging (TRLI) are generally disturbed by autofluorescence or surrounding oxygen in cells. Herein, we developed loose packing nanoaggregates with aggregation-induced delayed fluorescence (FKP-POA and FKP-PTA) and free from the effect of oxygen and autofluorescence for viscosity mapping via TRLI. The feasibility of FKP-PTA nanoparticles (NPs) for microviscosity mapping through TRLI was demonstrated by monitoring the variation of microviscosity inside HepG2 cancer cells, which demonstrated a value change from 14.9 cP to 216.9 cP during the apoptosis. This indicates that FKP-PTA NP can be used as a probe for cellular microviscosity mapping to help people to understand the physiologically dynamic microenvironment. The present results are expected to promote the advancement of diagnostic and therapeutic methods to cope with related diseases.

Abstract
It is a well-known fact that disruptions in the immune system and systemic inflammation are associated with accelerated atherosclerosis in rheumatoid arthritis (RA) patients. Elevated levels of tumor necrosis factor α (TNF-α), a major pro-inflammatory cytokine, are involved in endothelial cell activation of medium and large arteries, leading to increased endothelial permeability, generation of superoxide anion radical and hydrogen peroxide, and decreased availability of nitric oxide (NO). The present study aims to determine the influence of anti-TNF therapy and homocysteine (Hcy) levels on the carotid intima-media thickness (IMT) in patients with RA. Assessments were performed on 115 patients diagnosed with RA on biological treatment to determine the evolution of IMT and Hcy levels. Carotid ultrasonography was used to assess the IMT, as a fast and easy tool for the prediction of cardiovascular events in patients with RA. The first measurement of IMT was noted as IMT1, followed by a second measurement after 1 year, noted as IMT2. The group of patients was divided into approximately three equal groups, each being treated with a different biological product, respectively, etanercept, adalimumab, and infliximab. In the 3 groups, after 1 year of anti-TNF-α therapy, IMT2 progression was significantly reduced compared to baseline. No significant differences were found among the three groups of treatment. A strong association was observed between IMT1-IMT2 in the etanercept group (P<0.001, r=0.758), in the adalimumab group (P<0.001, r=0.761) and in the infliximab group (P<0.001, r=0.829). The low level of Hcy2 after 12 months of anti-TNF-α therapy was significantly correlated with a decrease in IMT2 (P<0.001) in patients who had a high level of Hcy and IMT >0.9 mm at baseline. The results from the present study showed that biological treatment and the low level of homocysteinemia reduced the cardiovascular risk in RA, regardless of the treatment chosen (infliximab, adalimumab, or etanercept).

Abstract
This study was designed to determine the efficacy of a new oral anticoagulant (NOAC) therapy for the prevention of endothelial dysfunction and atherosclerosis progression in patients with atrial fibrillation (AF). Sixty-five AF patients with a CHA2DS2-VASc score ≥2 without previous history of cardiovascular disease were registered and randomly assigned to either an NOAC group (dabigatran or rivaroxaban) or the warfarin group. Reactive hyperemia peripheral arterial tonometry (RH-PAT) measurements reflecting endothelial function were taken using Endo-PAT2000. Carotid intima–media thickness (IMT) was measured at baseline, 12 months, and 24 months, and several biomarkers were also analyzed. For the primary end point, the reactive hyperemia index (RHI) for the NOAC group was 1.5 ± 0.4 and that for the warfarin group was 1.6 ± 0.5. The left and right carotid IMT was 0.7 mm in the NOAC groups and 0.8 mm in the warfarin group. At 12 months, RHI was 1.6 ± 0.3 for the dabigatran group, 1.6 ± 0.5 for the rivaroxaban group, and 1.6 ± 0.3 for the warfarin group. The three groups did not differ statistically with respect to change in left and right carotid IMT at 12 and 24 months, respectively. The biomarkers for endothelial function and atherosclerosis were not significantly different. There was a trend of reduced P-selectin levels in the NOAC group compared to the warfarin group. In patients with AF, there were no significant differences in the prevention of endothelial dysfunction and atherosclerosis progression between the NOAC and warfarin groups.

Abstract
NEW FINDINGS What is the central question of this study? The aim was primarily to determine the effect of hypoxia on microvascular function and secondarily whether superior cardiorespiratory fitness is protective against hypoxia-induced impairment in vascular function. What is the main finding and its importance? Hypoxia reduced endothelium-dependent but not endothelium-independent microvascular function. The extent of impairment was twofold higher in the microcirculation compared with the large blood vessels. This study suggests that individuals with superior cardiorespiratory fitness might preserve microvascular function in hypoxia. These findings highlight the sensitivity of the microvascular circulation to hypoxia. ABSTRACT Hypoxia is associated with diminished bioavailability of the endothelium-derived vasodilator, nitric oxide (NO). Diminished NO bioavailability can have deleterious effects on endothelial function. The endothelium is a heterogeneous tissue; therefore, a comprehensive assessment of endothelial function is crucial to understand the significance of hypoxia-induced endothelial dysfunction. We hypothesized that acute hypoxia would have a deleterious effect on microvascular and large vessel endothelial function. Twenty-nine healthy adults [24 (SD = 4 ) years of age] completed normoxic and hypoxic [inspired O2 fraction = 0.209] trials in this double-blinded, counterbalanced crossover study. After 30 min, we assessed the laser Doppler imaging-determined perfusion response to iontophoresis of ACh as a measure of endothelium-dependent microvascular function and iontophoresis of sodium nitroprusside as a measure of endothelium-independent microvascular function. After 60 min, we assessed brachial flow-mediated dilatation as a measure of large vessel endothelial function. Thirty minutes of hypoxia reduced endothelium-dependent microvascular function determined by the perfusion response to ACh (median difference (x̃∆) = -109% {interquartile range: 542.7}, P < 0.05), but not endothelium-independent microvascular function determined by the perfusion response to sodium nitroprusside (x̃∆ = 69% {interquartile range: 453.7}, P = 0.6). In addition, 60 min of hypoxia reduced allometrically scaled flow-mediated dilatation compared with normoxia ( x ¯ Δ = - 1.19 [95% CI = -1.80, -0.58 (Confidence Intervals)]%, P < 0.001). The decrease in microvascular endothelial function was associated with cardiorespiratory fitness (r = 0.45, P = 0.02). In conclusion, acute exposure to normobaric hypoxia significantly reduced endothelium-dependent vasodilatory capacity in small and large vessels. Collectively, these findings highlight the sensitivity of the microvascular circulation to hypoxic insult, particularly in those with poor cardiorespiratory fitness.

Abstract
Hepatitis C virus (HCV), a global health concern, has been linked to various hepatic and extrahepatic deleterious manifestations. Several observational studies have either supported the increased likelihood of coronary and carotid atherosclerosis after infection with HCV or refuted it. To date, there has been no clear consensus to support either train of thought, as randomized, controlled clinical trials have not been completed. In this review, we first discuss articles that support the notion that HCV infection leads to increased plaque formation due to systemic inflammation and then focus on articles that refute this idea. From the literature, we do know that both inflammatory and lipid processes play a role in plaque formation, and thus both components are important in the successful treatment of atherosclerosis. Based on our review of the literature, we do believe that HCV-infected individuals are at an increased risk for more severe coronary artery disease than their healthy counterparts. Although there is no irrefutable evidence that links HCV infection with plaque formation and/or rupture, cardioprotective measures should be taken to reduce poor health outcomes, especially in those individuals who are already at risk of coronary disease.

Abstract
Atherosclerosis-considered the major cause of cardiovascular diseases (CVDs)-is strongly associated with obesity, to which it strongly contributes. Moreover, atherosclerosis is characterised by a long asymptomatic phase, and its progression can lead to serious cardiovascular (CV) events. The carotid intima-media thickness (cIMT) has been determined as a predictor of CV events, as well as a marker of subclinical atherosclerosis, and has been used in clinical trials as an alternative assessment method or a surrogate endpoint. It should be noted that several behavioural approaches can directly influence the cIMT values, and decrease or increase the CV risk. In our paper, we aimed to summarize the current knowledge regarding IMT measurement among patients with obesity as a risk group-also in terms of the obesity paradox where the diagnosis of subclinical atherosclerosis is especially essential and implements the early therapeutic approach. We also summarized behavioural, modifiable factors, such as the Mediterranean diet, the Dietary Approach to Stop Hypertension Diets, body weight reduction or the intake of micro- and macronutrients, with a particular focus on the studies where the cIMT values were one of the outcomes. In order to collect the literature data related to the presented topic, the PubMed database was explored.

Abstract
BACKGROUND & AIMS Nonalcoholic fatty liver disease (NAFLD) was described for the first time in 1980, and became within a few years one of the most frequent causes of chronic liver disease. However, during the last decade, many studies suggested a strong relationship between NAFLD and cardiovascular diseases including carotid atherosclerosis evoking the hypothesis that NAFLD is a factor or a marker of cardiovascular risk. In Algeria, data on this subject are rare or inexistent. The objective of our work was to study the relationship between NAFLD and atherosclerosis in an Algerian population without diabetes. PATIENTS AND METHODS It is a case-control study with a strict matching by age and sex. Non-diabetic participants between 30 and 70 years of age were consecutively included in the department of internal medicine of the public hospital of El Biar. The diagnosis of NAFLD was made by ultrasound and hepatic elasticity was assessed by FibroScan®. We collected the data of the carotid ultrasound, the carotid-femoral pulse wave velocity (cfPWV), ankle-brachial pressure index and arterial pressure (consultation and ambulatory monitoring). Non parametric statistical methods (chi 2 McNemar for the percentages, t Friedman test for medium) were used and the association between variables was estimated by odds ratio (OR). These analyses were performed using SPSS 21.0 software (IBM). RESULTS 213 patients with NAFLD, with a mean age of 48.5 years±10.14 (100 men/113 women) were matched to 213 controls. The presence of carotid atherosclerotic plaque (CAP) was higher in NAFLD than in controls (31.92% (n=68) vs. 7.05% (n=15), P<0.001). In multivariate analysis, the CAP (OR 8.6, 95% CI [3.6-20.5], P<0.001), high Intima media thickness (OR 2.8, 95% CI [1.4-5.4], P=0.002), CRP≥6mg/l (OR 14.7, 95% CI [5.9-36.9], P=0.001), abdominal obesity (OR 3.8, 95% CI [1.4-9.7], P=0.05), high cfPWV (OR 4.4, 95% CI [2.4-8.1], P<0.001), elevated alanine aminotransferase(OR 4.0, 95% CI [1.6-9.8], P=0.002), overall obesity (OR 2.0, 95% CI [1.0-3.8], P=0.03), dyslipidemia (OR 2.0, 95% CI [1.0-3.8], P=0.02), and elevated GGT (OR 2.8, 95% [1.1-7.1] were independently associated to NAFLD. CONCLUSION Our study suggests that NAFLD is significantly associated with carotid atherosclerosis and arterial stiffness. These results may have implications in the management of patients with NAFLD in terms of cardiovascular prevention.

Abstract
Aims:
The utility of carotid intima-media thickness (cIMT) as a marker for coronary heart disease is under heavy debate. This is predominantly due to the lack of a standard definition of cIMT, leading to inconsistent results. We investigated and compared the relationships of five different measures of cIMT with coronary calcium.
Methods:
Japanese men aged 40-79y (
n
=869) from Shiga Epidemiological Study of Subclinical Atherosclerosis were examined. Mean cIMT was measured in three segments of the carotid arteries: common carotid artery (CCA
mean
), internal carotid artery (ICA
mean
) and bifurcation (Bif
mean
). Mean cIMT of average values (Mean cIMT) and mean cIMT of maximum values (Mean-Max cIMT) of all segments combined were assessed. Coronary calcium was assessed as coronary artery calcification (CAC). Ordinal logistic regression was used to determine the odds ratio (OR) of higher CAC per 1 standard deviation higher cIMT measure. Analyses were adjusted for cardiovascular covariates and stratified by age quartiles.
Results:
All cIMT measures had positive associations with CAC (
p
<0.001): [OR, 95% Confidence Interval]: ICA
mean
[1.23, 1.07-1.42], CCA
mean
[1.27, 1.08-1.49], Bif
mean
[1.33, 1.15-1.53], Mean cIMT [1.42, 1.22-1.66], and Mean-Max [1.50, 1.28-1.75]. In age-stratified analyses, only Mean-Max cIMT maintained a significant relationship with CAC in every age quartile (
p
<0.05), while CCA
mean
had some of the weakest associations among age quartiles.
Conclusions:
Mean-Max cIMT had consistently stronger associations with coronary calcium, independent of important confounders, such as age. The most oft-used measure, CCA
mean
, was no longer associated with coronary calcium after age-adjustment and stratification.

Abstract
OBJECTIVES Inflammation plays an important role in the development of atherosclerotic vascular disease, which is the leading cause of morbidity and mortality in the adult population. Several clinical trials have shown that suppression of the inflammatory response can delay or decrease the atherosclerotic process. The aim of this study was to investigate carotid intima-media thickness (CIMT) between patients with chronic disease history plus gout using colchicine and patients with cardiovascular risk factors. MATERIALS AND METHODS In total, 102 patients (85 female, 17 male) were included. There were two groups in the study: Group 1 - patients with chronic diseases including cardiovascular risk factors plus gout using colchicine (0,5 mg twice a day); and Group 2 - patients with chronic diseases including cardiovascular risk factors only. All patients underwent ultrasonography for the measurement of CIMT. Additionally, the serum concentrations of C-reactive protein (CRP) and the levels of lipids such as cholesterol, triglyceride, LDL, HDL were measured. RESULTS The mean age of patients was 62.35±6.68 years and 64.27±5.32 years in Group 1 and Group 2, respectively. There was also no statistically significant difference in the levels of lipids between groups (p>0.05). The value of CIMT and CRP in Group 1 and Group 2 were 0.98±0.20 and 0.26±0.14, 1.18±0.15 and 0.58±0.42, respectively. There was a statistically significant difference between groups (p<0.05). The colchicine group was found to have a statistically significant lowering of CIMT and CRP compared to the non-colchicine group. CONCLUSIONS It appears that colchicine in addition to statins and other standard treatments is an effective treatment for the interception of cardiovascular and cerebrovascular events in patients with cardiovascular risk factors.

Association of Hepatic Steatosis Index and Fatty Liver Index with Carotid Atherosclerosis in Type 2 Diabetes. Int J Med Sci 2021; 18:3280-3289. [PMID: 34400897 PMCID: PMC8364463 DOI: 10.7150/ijms.62010] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 07/12/2021] [Indexed: 12/22/2022] Open
Abstract
Background/aim: Previous studies have suggested that the hepatic steatosis index (HSI) and fatty liver index (FLI) can be used as a predictor of non-alcoholic fatty liver disease (NAFLD). The aim of our study was to determine whether non-invasive indices of hepatic steatosis (HSI and FLI) are associated with carotid atherosclerosis in type 2 diabetes mellitus (T2DM). Methods: This was a cross-sectional study conducted in the T2DM patients (n=768). Carotid intima-media thickness (CIMT) was measured by the Color Doppler ultrasound. The HSI was calculated based on gender, body mass index (BMI), and transaminases level. The FLI was based on BMI, waist circumference (WC), triacylglycerols (TG) and g-glutamyl transferase (GGT). Results: Raised HSI and FLI levels was associated with increased CIMT levels in T2DM patients. Patients with greater CIMT had higher HSI (39.10 ± 5.70 vs 36.10 ± 4.18, P < 0.001) and FLI (46.35 (29.96, 65.54) vs 36.93 (18.7, 57.93), P < 0.001) than those with lower CIMT. Subjects with existing carotid plaque had higher HSI (38.28 ± 5.63 vs 35.69 ± 3.45 P < 0.001) and FLI (47.41 (27.77, 66.62) vs 37.19 (17.71, 51.78), P < 0.001) accordingly. HSI (r = 0.343, P < 0.001) and FLI (r = 0.184, P < 0.001) were positively related with the CIMT. In the linear regression, after full adjustment metabolic risk factors, smoking, and measures of insulin resistance, HSI and FLI were independently associated with CIMT (HSI: β = 0.011, FLI: β = 0.001, all P < 0.01). Further, logistic regression analyses showed that higher HSI and FLI had an impact on the risk for carotid atherosclerosis [HSI: OR (95%CI): 1.174 (1.123-1.228), FLI: OR (95%CI): 1.011(1.004-1.019), all P < 0.01]. Overall, increasing values of HSI and FLI were associated with CIMT (P < 0.05) significantly across different categories of age and hypertension. Conclusion: Current data suggest HSI and FLI are independently correlated with carotid atherosclerosis in T2DM. They may be a simple and useful marker for assessing the progression of diabetic macrovascular complications.

Comprehensive assessment of cardiovascular structure and function and disease risk in middle-aged ultra-endurance athletes. Atherosclerosis 2020; 320:105-111.

Abstract
BACKGROUND AND AIMS Recent studies suggest that long-term endurance training may be damaging to the heart, thus increasing cardiovascular disease (CVD) risk. However, studies utilizing cardiac imaging are conflicting and lack measures of central and peripheral vascular structure and function, which are also independently predictive of CVD events. METHODS We performed a comprehensive assessment of cardiovascular structure and function in long-term (≥ 10 years) ultra-endurance athletes (ATH, 14 M/11 F, 50 ± 1 y) and physically active controls (CON, 9 M/9 F, 49 ± 2 y). RESULTS As expected, left ventricular mass and end-diastolic volume (echocardiography) were greater in ATH vs CON, whereas there was no difference in cardiac function at rest. Coronary artery calcium scores (computed tomography) were not statistically different between groups. There was no evidence of myocardial fibrosis (contrast magnetic resonance imaging) in any subject. Aortic stiffness (carotid-femoral pulse wave velocity) was lower in ATH vs CON (6.2 ± 0.2 vs 6.9 ± 0.2 m/s, p < 0.05), whereas carotid intima-media thickness (ultrasound) was not different between groups. Peripheral vascular endothelial function (flow-mediated vasodilation of the brachial artery) and microvascular function (peak blood velocity) in response to 5 min of forearm ischemia were not different between groups. Furthermore, there was no difference in 10-year coronary heart disease risk (ATH; 2.3 ± 0.5 vs CON; 1.6 ± 0.2%, p > 0.05). CONCLUSIONS Our data indicate that middle-aged ultra-endurance ATH do not have marked signs of widespread cardiovascular dysfunction or elevated CHD risk compared to CON meeting physical activity guidelines.

Abstract
OBJECTIVES Observational studies suggest that the risk of cardiovascular disease increases during menopause; however, the menopause-related risk of subclinical atherosclerosis is unclear. The aim of the current study is to evaluate menopause and the risk of subclinical carotid atherosclerosis through a retrospective analysis of data from a population-based prospective cohort study. STUDY DESIGN The study sample comprised 879 women in the Beijing community enrolled in the Chinese Multi-provincial Cohort Study at baseline study in 1992 and followed up to at least one carotid ultrasound examination at three on-site follow-up surveys. Age at menopause was categorized as <40 years (premature menopause), 40-44 years (early menopause), 45-49 years (relatively early menopause), 50-51 years (reference), and >51 years (relatively late menopause). Menopause staging at baseline was categorized as: reproductive, menopausal transition/perimenopause, early postmenopause, and late postmenopause. Menopause as a time-varying covariate was calculated using waiting time to menopause and menopause status at the last follow-up (2012). MAIN OUTCOME MEASURES The main outcome measures included carotid plaque and intima-media thickening. Gray's test was performed to assess the equality of cumulative incidence functions between age groups at menopause and between menopause stages. Multivariate Cox regression models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) associated with menopause. RESULTS Of the 879 women included (mean [SD] age at baseline, 48.6 [8.1] years), 573 (65.2%) developed carotid plaques and 430 (48.9%) developed intima-media thickening during follow-up. Menopause was significantly associated with risk of developing carotid plaques (HR 1.93, 95% CI 1.05-3.54; P = 0.03) after adjustment for age at baseline, age at menopause, use of oral estrogen due to menopause, and traditional cardiovascular risk factors at baseline. No significant association was found between age at menopause and risk of carotid atherosclerosis. CONCLUSION Menopausal women, irrespective of age at menopause, had an increased risk of carotid plaque.

Abstract
PURPOSE To investigate factors associated with poor visual acuity (VA) in branch retinal artery occlusion (BRAO). METHODS This was a retrospective cross-sectional study of 72 eyes with BRAO of 72 patients. For statistical comparison, we divided the patients into worse-VA (decimal VA < 0.5) and better-VA (decimal VA > = 0.5) groups. We examined the association of clinical findings, including blood biochemical test data and carotid artery ultrasound parameters, with poor VA. RESULTS Median age, hematocrit, hemoglobin and high-density lipoprotein (HDL) differed significantly between the groups (P = 0.018, P < 0.01, P < 0.01, and P = 0.025). There was a tendency towards higher median IMT-Bmax in the worse-VA group (worse-VA vs. better-VA: 2.70 mm vs. 1.60 mm, P = 0.152). Spearman's rank correlation test revealed that logMAR VA was significantly correlated to IMT-Bmax (rs = 0.31, P < 0.01) and IMT-Cmax (rs = 0.24, P = 0.035). Furthermore, logMAR VA was significantly correlated to HDL level (rs = -0.33, P < 0.01). Multivariate logistic regression analysis revealed that IMT-Bmax (odds ratio [OR] = 2.70, P = 0.049), HDL level (OR = 0.91, P = 0.032), and female gender (OR = 15.63, P = 0.032) were independently associated with worse VA in BRAO. CONCLUSIONS We found that increased IMT-Bmax, decreased HDL, and female sex were associated with poor VA in BRAO patients. Our findings might suggest novel risk factors for visual dysfunction in BRAO and may provide new insights into the pathomechanisms underlying BRAO.

Can vasohibin-1, an endothelium-derived angiogenesis inhibitor, be a marker of endothelial dysfunction in hemodialysis patients? Semin Dial 2020; 33:418-427.

Abstract
BACKGROUND Endothelial dysfunction (ED) is associated with high cardiovascular disease burden in hemodialysis (HD) patients. Vasohibin-1, an endothelium-derived angiogenesis inhibitor, is essential for endothelial cell survival, therefore it may be a promising marker of ED. We aimed to investigate whether vasohibin-1 levels are associated with ED markers in HD patients. METHODS Fifty HD patients and 30 healthy controls were included in the study. As markers of ED, endothelium-dependent flow-mediated dilatation (FMD), carotid intima-media thickness (CIMT), and pulse wave velocity (PWV) were examined. Serum vasohibin-1 levels were measured with ELISA. RESULTS Serum vasohibin-1 levels were low (387.7 ± 115.7 vs 450.1 ± 140.1 P = .02), FMDs' were impaired (6.65 ± 2.50 vs 10.95 ± 2.86 P < .001), PWV (7.92 ± 1.964 vs 6.79 ± 0.96 P = .01) and CIMT (0.95 ± 0.20 vs 0.60 ± 0.11 P < .001) were increased in HD patients compared to healthy controls. In regression analysis, vasohibin-1 levels were not related with FMD, PWV, or CIMT. CONCLUSIONS Hemodialysis patients have low serum vasohibin-1 levels but serum levels of vasohibin-1 did not show any significant relationship with FMD, PWV, and CIMT in HD patients. Since vasohibin-1 acts via paracrine pathways, serum levels may be insufficient to explain the relationship between vasohibin and ED. Local vasohibin-1 activity on tissue level may be more important instead of circulating levels.

Cruciferous vegetable intake is inversely associated with extensive abdominal aortic calcification in elderly women: a cross-sectional study. Br J Nutr 2020; 125:337-345.

Abstract
We have previously shown that higher intake of cruciferous vegetables is inversely associated with carotid artery intima-media thickness. To further test the hypothesis that an increased consumption of cruciferous vegetables is associated with reduced indicators of structural vascular disease in other areas of the vascular tree, we aimed to investigate the cross-sectional association between cruciferous vegetable intake and extensive calcification in the abdominal aorta. Dietary intake was assessed, using a FFQ, in 684 older women from the Calcium Intake Fracture Outcome Study. Cruciferous vegetables included cabbage, Brussels sprouts, cauliflower and broccoli. Abdominal aortic calcification (AAC) was scored using the Kauppila AAC24 scale on dual-energy X-ray absorptiometry lateral spine images and was categorised as ‘not extensive’ (0–5) or ‘extensive’ (≥6). Mean age was 74·9 (sd 2·6) years, median cruciferous vegetable intake was 28·2 (interquartile range 15·0–44·7) g/d and 128/684 (18·7 %) women had extensive AAC scores. Those with higher intakes of cruciferous vegetables (>44·6 g/d) were associated with a 46 % lower odds of having extensive AAC in comparison with those with lower intakes (<15·0 g/d) after adjustment for lifestyle, dietary and CVD risk factors (ORQ4 v. Q1 0·54, 95 % CI 0·30, 0·97, P = 0·036). Total vegetable intake and each of the other vegetable types were not related to extensive AAC (P > 0·05 for all). This study strengthens the hypothesis that higher intake of cruciferous vegetables may protect against vascular calcification.

Abstract
Background The present meta-analysis was conducted to confirm whether carotid intima-media thickness (IMT) could serve as an accurate diagnostic method for coronary artery disease (CAD). Methods Databases of PubMed, Google Scholar, and Embase were searched for potential articles. The articles were selected according to inclusion criteria. Pooled sensitivity and specificity with corresponding 95% confidence interval (CI) were used to confirm the diagnostic role of IMT for CAD. I 2 and P value were used to assess the existence of heterogeneity. I 2 and P value were used to assess the existence of heterogeneity. Results 22 eligible articles were selected in the present meta-analysis. Pooled sensitivity and specificity of IMT for diagnosing CAD were 0.68 (0.57-0.77) and 0.70 (0.64-0.75), respectively. The corresponding AUC was 0.74 (0.70-0.78). Subgroup analyses based on cutoff value of IMT were performed. A cutoff value of 1 mm was demonstrated to be much more accurate diagnostic criteria for CAD (sensitivity: 0.66; specificity: 0.79; AUC: 0.80). Sensitivity analysis indicated that the pooled results were robust. Deek's funnel plot indicated no significant publication bias (P value were used to assess the existence of heterogeneity. Conclusion Carotid IMT may serve as an accurate diagnostic tool. A cutoff value of 1 mm seems to provide much more accurate diagnostic results for CAD.

Abstract
Background Low-grade albuminuria has been considered a predictor of cardiovascular mortality. We investigated the relationship between high-normal albuminuria and subclinical atherosclerosis in non-diabetic men with estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2. Methods In this cross-sectional study, 1,756 men with eGFR ≥60 mL/min/1.73 m2 and urine albumin-to-creatinine ratio (UACR) <30 mg/g, who attended general health checkups between April 2012 and March 2015, underwent blood sampling, urinalysis, and carotid ultrasonography. We excluded the subjects who were diabetic and/or received an anti-hypertensive drug. Carotid intima-media thickness (IMT) and the number of focal atheromatous plaques were used as indicators of subclinical atherosclerosis. Multiple linear regression analysis was performed to identify clinical factors associated with carotid IMT. Poisson regression analysis was used to assess the determinants of the carotid plaque number. Results Median UACR was 4.8 mg/g (interquartile range, 3.6–6.9 mg/g). Compared with subjects with low-normal UACR (<10.0 mg/g), subjects with high-normal UACR (10.0–29.8 mg/g) had greater IMT and higher carotid plaque number. High-normal UACR was independently associated with thickened IMT in the model adjusted for conventional cardiovascular disease risk factors. Moreover, participants with high-normal UACR were also more likely to be associated with increased plaque count (prevalence ratio: 1.06; 95% confidence interval: 1.01–1.14) after adjustment for conventional cardiovascular disease risk factors. Conclusions Our results indicate that high-normal albuminuria is associated with both carotid IMT and plaque formation in the non-diabetic male population with eGFR ≥60 mL/min/1.73 m2.

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
Cerebrovascular diseases pose a serious threat to human survival and quality of life and represent a major cause of human death and disability. Recently, the incidence of cerebrovascular diseases has increased yearly. Rapid and accurate diagnosis and evaluation of cerebrovascular diseases are of great importance to reduce the incidence, morbidity and mortality of cerebrovascular diseases. With the rapid development of medical ultrasound, the clinical relationship between ultrasound imaging technology and the diagnosis and treatment of cerebrovascular diseases has become increasingly close. Ultrasound techniques such as transcranial acoustic angiography, doppler energy imaging, three-dimensional craniocerebral imaging and ultrasound thrombolysis are novel and valuable techniques in the study of cerebrovascular diseases. In this review, we introduce some of the new ultrasound techniques from both published studies and ongoing trials that have been confirmed to be convenient and effective methods. However, additional evidence from future studies will be required before some of these techniques can be widely applied or recommended as alternatives.

Abstract
Aim Arteriosclerotic disease is increasing due to aging of the population, and is associated with diabetes, hypertension, hyperlipidemia, obesity, and smoking. This disease may result in fatal cerebrovascular disease, and especially cardiogenic cerebral embolism caused by artery plaque-based atherothrombotic cerebral infarction. The study was performed to examine the relationship of abdominal aortic calcification (AAC) on lumbar radiographs with carotid intima-media complex thickness (IMT), factors associated with carotid artery plaque, and cutoff values in middle-aged and elderly people. Patients and methods The subjects were 309 healthy volunteers (average age 63 years) who attended a health checkup supported by a local government in 2015. The AAC-24 score was determined on lumbar lateral standing radiographs and was categorized as 0 (54% of subjects),1–4 (31%), and ≥5 (severe, 15%). Carotid ultrasonography was used to evaluate IMT of the common carotid artery. Carotid artery plaque was defined as IMT >1.1 mm. Body mass index (BMI), hypertension, diabetes mellitus (DM), dyslipidemia, smoking, alcohol intake, and osteoporosis were examined. Results Of 309 cases, 142 (46%) had AAC and 104 (34%) had carotid artery plaque. Thus, 15% (n = 45) had severe AAC. Age, prevalence of DM and carotid artery plaque increased with severity of AAC. In patients with carotid artery plaque (n = 104), age (67.8±7.5 vs. 61.0±10.1 years), % male (56% vs. 39%), BMI (22.9±2.8 vs. 23.7±3.5), AAC rate (58% vs. 40%) and AAC-24 score (3 (0, 8) vs. 0 (0, 2)) were all significantly higher than in those (n = 205) without carotid artery plaque. In multivariate analysis, age (OR 1.172), male gender (OR 1.654), AAC (OR 1.352), and AAC-24 ≥5 (OR 4.191) were significantly associated with carotid artery plaque. Combining AAC-24 with age significantly increased the AUC from 0.632 to 0.834 (p<0.05). Conclusion There was a significant relationship between AAC on lumbar radiographs and carotid IMT.

Abstract
PURPOSE The aim of this study was to analyze the association of the carotid intima-media thickness (CIMT) with various parameters in patients on maintenance hemodialysis (mHD). METHODS A cross-sectional study was conducted, enrolling 68 subjects (41 men, 27 women) on mHD in the Hemodialysis Unit, Sanglah Hospital, Denpasar, Indonesia. CIMT was measured with B-mode ultrasonography using a USG Sonoace 8000 and a 7.5 MHz linear transducer. RESULTS CIMT was higher in subjects with cardiovascular disease (CVD) compared with those without CVD (0.6494 vs 0.7288 mm; P=0.026), and in men compared with women (0.7056 vs 0.6141 mm; P=0.003). CIMT was correlated with age (R=0.607; P<0.001), plasma albumin (R=-0.291, P=0.016), serum phosphate (R=-0.294, P=0.015), calcium-phosphate product (R=-0.284, P=0.011), and plasma high-sensitivity C-reactive protein (R=0.279, P=0.030). However, after multiple linear regression testing, only age consistently had a role in determining the CIMT value (β=0.452, P<0.001). CONCLUSION Subjects with CVD have higher CIMT than those without CVD and men had higher CIMT than women. In addition, older age, higher high-sensitivity C-reactive protein, and lower albumin, phosphate, and calcium-phosphate product levels were correlated with higher CIMT. Age was the most important marker for CIMT in subjects on mHD.

Abstract
Tangier disease is a rare disorder of lipoprotein metabolism that presents with extremely low levels of HDL cholesterol and apoprotein A-I. It is caused by mutations in the ATP-binding cassette transporter A1 (ABCA1) gene. Clinical heterogeneity and mutational pattern of Tangier disease are poorly characterized. Moreover, also familial HDL deficiency may be caused by mutations in ABCA1 gene. ATP-binding cassette transporter A1 (ABCA1) gene mutations in a patient with Tangier disease, who presented an uncommon clinical history, and in his family were found and characterized. He was found to be compound heterozygous for two intronic mutations of ABCA1 gene, causing abnormal pre-mRNAs splicing. The novel c.1510-1G > A mutation was located in intron 12 and caused the activation of a cryptic splice site in exon 13, which determined the loss of 22 amino acids of exon 13 with the introduction of a premature stop codon. Five heterozygous carriers of this mutation were also found in proband's family, all presenting reduced HDL cholesterol and ApoAI (0.86 ± 0.16 mmol/L and 92.2 ± 10.9 mg/dL respectively), but not the typical features of Tangier disease, a phenotype compatible with the diagnosis of familial HDL deficiency. The other known mutation c.1195-27G > A was confirmed to cause aberrant retention of 25 nucleotides of intron 10 leading to the insertion of a stop codon after 20 amino acids of exon 11. Heterozygous carriers of this mutation also showed the clinical phenotype of familial HDL deficiency. Our study extends the catalog of pathogenic intronic mutations affecting ABCA1 pre-mRNA splicing. In a large family, a clear demonstration that the same mutations may cause Tangier disease (if in compound heterozygosis) or familial HDL deficiency (if in heterozygosis) is provided.

Kaydu A, Güven DD, Gökcek E. Can ultrasonographic measurement of carotid intima-media thickness predict hypotension after induction of general anesthesia? J Clin Monit Comput 2018; 33:825-832. [PMID: 30465109 DOI: 10.1007/s10877-018-0228-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Accepted: 11/16/2018] [Indexed: 02/06/2023]
Abstract
Hypotension in patients under general anesthesia is prevalent and causes unfavorable outcomes. Carotid intima-media thickness (CIMT) is a surrogate marker for atherosclerosis and useful for evaluating the risk of cardiovascular diseases. We investigated the usefulness of preoperative CIMT measurement as a predictor of post-induction hypotension (PIH). The ultrasonographic measurement of CIMT was performed preoperatively on 82 patients scheduled for elective surgery under general anesthesia in a prospective, observational study. Mean blood pressure (MBP) was recorded before induction. Hypotension was defined as a 20% decrease in MBP from baseline. The ultrasonographic measurement of CIMT was unsuccessful in 2 (2.43%) patients, leaving 80 patients for analyses. Hypotension developed in 41 patients. CIMT was higher in the patient group with PIH than in the group without PIH (p < 0.001). There was statistically significant correlation between MBP decrease after induction and CIMT (r = 0.529, p < 0.0001). CIMT correlated positively with age (r = 0.739, p < 0.0001). The area under curve for CIMT was 0.753 [95% confidence interval (CI) 0.642-0.863]. The optimal cutoff value of CIMT was 0.65 mm with a sensitivity of 75.6% and a specificity of 74.4%. CIMT was an independent predictor of PIH after adjusting other factors with an odds ratio of 1.833 (95% CI 1.23-2.72; p = 0.003). The ultrasonographic imaging and measurement of CIMT can reliably predict hypotension with a 0.65-mm threshold level. We believe that the ultrasonographic measurements of CIMT may be included in point-of-care application in anesthesiology.
