Objective The management of blood pressure (BP) in hypertensive patients is the key to preventing a progression of organ damage. The brachial BP (bBP) has been used as the representative method for measuring the BP. The central BP (cBP), which is, different from the bBP due to the propagation and the reflection of the pulse wave in the arterial system, has recently received attention because it can now be estimated non-invasively. We examined the relationships between the difference in the central systolic BP (csBP) and the brachial systolic BP (bsBP) (Δ) and other factors in hypertensive patients...

BACKGROUND: Atherosclerosis is regarded as a combination of two major separate diseases: atherosis and sclerosis. Sclerotic component depends on deterioration of elastic properties of the aortic wall and is called aortic stiffness. The most valuable, non-invasive method of aortic stiffness assessment is echocardiography, which allows to calculate the aortic stiffness index (ASI). ASI is an independent predictor of all-cause and cardiovascular mortality in different groups of patients...

BACKGROUND: Failure of physiologic transformation of spiral arteries has been reported in preeclampsia, fetal growth restriction, fetal death, and spontaneous preterm labor with intact or ruptured membranes. Spiral arteries with failure of physiologic transformation are prone to develop atherosclerotic-like lesions of atherosis. There are striking parallels between preeclampsia and atherosclerotic disease, and between lesions of atherosis and atherosclerosis. Endothelial activation, identified by intercellular adhesion molecule-1 expression, is present in atherosclerotic-like lesions of heart transplantation, and is considered a manifestation of rejection...

OBJECTIVES: Pre-eclampsia (PE) is a pregnancy-specific hypertensive disorder that has been associated with cardiovascular risk factors and vascular changes, such as acute atherosis in placental blood vessels, similar to early-stage atherosclerosis. The objective of this study was to determine whether women with PE have increased atherosclerotic burden, as determined by the carotid intima-media thickness (CIMT), compared with women without PE. METHODS: We conducted a systematic review and meta-analysis of studies that reported CIMT, a non-invasive, ultrasound-based measure of subclinical atherosclerosis, in women who did vs those who did not have PE...

Although intravascular thrombi and infarct-type necrosis have been reported in leiomyomas following with tranexamic acid therapy, intratumoral vasculopathy resembling acute atherosis has not been reported to date in patients without exposure to gonadotropin receptor agonist. We describe a case of intratumoral vasculopathy resembling acute atherosis in a leiomyoma in a 49-year-old woman, with hereditary hemorrhagic telangiectasia and menorrhagia, treated with tranexamic acid. The patient had no exposure to gonadotropin receptor agonists...

BACKGROUND: Women with a history of placental bed disorders, including preeclampsia and intrauterine growth restriction have an increased long-term risk of cardiovascular disease (CVD). Further, similarities exist between atherosclerosis and abnormalities observed in placental bed spiral arteries in pregnancies affected by preeclampsia and intrauterine growth restriction, such as acute atherosis and defective remodeling. This suggests a common pathophysiological pathway underlying both disorders...

Xanthohumol may prevent and cure diabetes and atherosis, have oxidation resistance and antiviral function as well as anticancer effect preventing cancer cell metastasis. We investigate whether the anticancer effect of xanthohumol induces growth inhibition and apoptosis of human liver cancer through NF-κB/p53-apoptosis signaling pathway. Human liver cancer HepG2 cell were treated with 10, 20, 30 and 40 µM xanthohumol for 48 h. The present study showed that the anticancer effect of xanthohumol was effective in inhibiting proliferation and inducing apoptosis of human liver cancer HepG2 cells...

BACKGROUND: Acute atherosis (AA) of the uteroplacental spiral arteries has been characterised by subendothelial lipid-laden foam cells, perivascular leukocyte infiltrates (PVI) and fibrinoid necrosis. Because precise diagnostic criteria are not available for comparative research studies we developed and tested new simplified criteria based on 237 cases. METHODS: Decidual basalis samples were collected by vacuum suction at elective cesarean deliveries. Spiral arteries were evaluated in serial decidual tissue sections from women with normal pregnancy, preeclampsia, and diabetes...

Placental villi play pivotal roles in feto-maternal transportation and phospholipids constitute a major part of the villous membrane. We have been developing and optimizing an imaging system based on a matrix-assisted laser desorption/ionization (MALDI)-based mass spectrometer, which provides clear two-dimensional molecular distribution patterns using highly sensitive mass spectrometry from mixtures of ions generated on tissue surfaces. We recently applied this technology to normal human uncomplicated term placentas and detected the specific distribution of sphingomyelin (SM) (d18:1/16:0) in stem villi and phosphatidylcholine (PC) (16:0/20:4) in terminal villi...

Joo-Yeon Kim, Yeon Mee Kim
Acute atherosis is unique vascular changes of the placenta associated with poor placentation. It is characterized by subendothelial lipid-filled foam cells, fibrinoid necrosis of the arterial wall, perivascular lymphocytic infiltration, and it is histologically similar to early-stage atherosclerosis. Acute atherosis is rare in normal pregnancies, but is frequently observed in non- transformed spiral arteries in abnormal pregnancies, such as preeclampsia, small for gestational age (SGA), fetal death, spontaneous preterm labor and preterm premature rupture of membranes...

Arnold E Eggers
The hypothesis is set forth that maternal release of epinephrine in the adrenal medulla causes systemic platelet activation (SPA) which, in turn, initiates coagulation via the intrinsic pathway and leads to thrombin generation. Thrombin causes inflammation, which is the underlying cause of acute atherosis in preeclampsia (PE). Each step of this cascade is examined in detail and supporting literature documented. SPA is associated with migraine headaches, which are a prominent clinical feature of PE and may help explain why PE is a risk factor for future maternal cardiovascular disease...

For many years pre eclampsia has been considered to be a two-stage disease. The first stage comprises poor placentation. The second stage is the clinical expression of the disease namely new hypertension and new proteinuria. The first stage is preclinical and symptomless, which evolves between weeks 8 and 18 of pregnancy, when the uteroplacental circulation is established by spiral artery remodelling. Its consequence is dysfunctional perfusion of the intervillous space of the placenta with oxidative and haemodynamic stress...

Stroke is the second most common cause of mortality worldwide, and it is a major cause of physical disability. Several genome-wide association studies have yielded numerous common variants which increase the risk of ischemic stroke, including the Kalirin-coding gene, KALRN. KALRN strongly associates with early-onset coronary artery disease and atherosclerosis and plays an important role in stroke in the European population. In this study, we analyzed four KALRN gene SNPs in 503 ischemic stroke patients and 493 control subjects, separating the patients into separate research groups based on comorbidity with hypertension or diabetes and stroke type (atherosis or lacunar and combination type)...

INTRODUCTION: Chronic villitis of unknown etiology (CVUE) and massive chronic intervillositis (MCI) are placental lesions associated with infiltration of mononuclear cells in the chorionic villi and the intervillous spaces, respectively. It is not well known whether immune cells in CVUE and MCI have similar phenotypic characteristics. METHODS: A cross-sectional study of third trimester placentas was conducted to identify immune cell subpopulations in CVUE and MCI (n = 17/group)...

BACKGROUND: We sought to evaluate the effects of a strong lipophilic statin (pitavastatin) on plaque components and morphology assessed by transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE), as well as plaque inflammation assessed by 18F-fluorodeoxyglucose (FDG) PET/CT in the thoracic aorta and the carotid artery. Furthermore, we compared the effects of pitavastatin with those of mild hydrophilic statin (pravastatin). METHODS: We examined atherosclerotic plaques in the thoracic aorta by TEE and those in the carotid artery by integrated backscatter (IBS)-TTE and PET/CT...

Endometrial ablation is a minimally invasive alternative to hysterectomy for abnormal uterine bleeding. Although the failure rate is low, continued bleeding or development of pelvic pain after ablation does occur. We analyzed the clinicopathologic features of 164 hysterectomy specimens after endometrial ablation, 19 of which were performed for indications other than failed ablation (control cases). Pathologic findings included: dense fibrosis and hyalinization of the endometrial surface ablative necrosis within the uterine cavity and adherent to the endometrial surface, persistent months after ablation; uterine cavity lined by superficial, large, congested, patent blood vessels with atherosis; ablation changes present only in the lower uterine segment; and residual endometrium present in the cornual regions...

OBJECTIVE: Acute atherosis is characterized by subendothelial lipid-filled foam cells, fibrinoid necrosis and perivascular lymphocytic infiltration. This lesion is generally confined to non-transformed spiral arteries and is frequently observed in patients with preeclampsia. However, the frequency of acute atherosis in the great obstetrical syndromes is unknown. The purpose of this study was to determine the frequency and topographic distribution of acute atherosis in placentas and placental bed biopsy samples obtained from women with normal pregnancy and those affected by the "great obstetrical syndromes"...

OBJECTIVE: Acute atherosis is a lesion of the spiral arteries characterized by fibrinoid necrosis of the vessel wall, an accumulation of fat-containing macrophages, and a mononuclear perivascular infiltrate, which can be found in patients with preeclampsia, fetal death, small-for-gestational age, spontaneous preterm labor/premature prelabor rupture of membrane, and spontaneous mid-trimester abortion. This lesion is thought to decrease blood flow to the intervillous space which may lead to other vascular lesions of the placenta...
