OBJECTIVES: Preeclampsia is associated with impaired trophoblast invasion and typical villous and vascular placental lesions. The primary aim was to conduct a systematic review in order to quantify the prevalence of placental histopathological lesions in pregnancies complicated by preeclampsia. METHODS: MEDLINE, EMBASE and CINAHL were searched electronically and relevant articles reporting placental histopathological lesions were assessed according to the following criteria: study design, number of pregnancies, type of preeclampsia and whether the pathologist was blinded to the clinical information...

BACKGROUND: Systemic treatment with sirolimus, as used for immunosuppression in transplant patients, results in markedly low rates of in-stent restenosis. Since the underlying mechanisms remain obscure, we aimed to determine the molecular and cellular effects of systemic sirolimus treatment on vascular remodeling processes. METHODS AND RESULTS: Systemic sirolimus treatment significantly reduced smooth muscle cell (SMC) proliferation 14days after wire-induced injury and neointima formation 28days after injury in C57BL/6 mice, while simultaneously impairing re-endothelialization...

Beneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates. 29 BVS were deployed in 9 CTO lesions revascularization (mean J-CTO score ≥3) with an acute procedural success rate of 100%...

BACKGROUND: Vascular cognitive impairment (VCI) results from cerebrovascular disease, and worldwide, it is the second most common type of cognitive dysfunction. While targeted aerobic training is a promising approach to delay the progression of VCI by reducing cardiometabolic risk factors, few randomised controlled trials to date have specifically assessed the efficacy of aerobic training on cognitive and brain outcomes in this group at risk for functional decline. AIM: To examine the effect of moderate-intensity aerobic training on executive functions and functional neural activity among older adults with mild subcortical ischaemic VCI (SIVCI)...

Imaging of the orbit plays an important role in the workup of orbital emergencies. Orbital imaging is particularly useful in the emergency department, where clinical history and physical examination may be limited or delayed until the exclusion or treatment of more life-threatening conditions. Cross-sectional orbital imaging with multidetector computed tomography (CT) and magnetic resonance (MR) imaging is commonly performed in addition to ultrasonography. In an emergent setting, CT is the preferred modality when evaluating for intraorbital foreign bodies, fractures, or calcifications within a mass lesion...

<i><b>Introduction</b>: Mixed dementia (MixD) refers to a combination of definite Alzheimer's disease (AD) and vascular encephalopathy. The existence of a "pure" type of vascular dementia (VaD) is controversial. There is a need to find magnetic resonance imaging (MRI) characteristics allowing the distinction between VaD and MixD. The present post-mortem 7.0-tesla MRI compares the frequency or severity and the topography of the small cerebrovascular lesions in brains of patients with VaD and with MixD...

There is substantial evidence implicating the urokinase system in tissue remodeling during neo-vascularization, inflammation, tumor invasion, and metastasis. Regulated degradation of the extracellular matrix at the leading edge of migrating cells, mediated by uPA and uPAR, is required for tissue remodeling, invasiveness, and angiogenesis. Psoriasis and basal cell carcinoma (BCC) are the most common skin diseases. Pathogenesis of both of them is associated with keratinocyte hyperproliferation, inflammatory cell migration, and angiogenesis-processes in which the plasminogen system (uPA, uPAR, tPA, and PAI-1) plays a crucial role...

A 46-year-old woman was referred to our hospital because of nausea. Endoscopy revealed scirrhous gastric cancer, and abdominalcomputed tomography revealed peritonealdissemination. She was diagnosed with Stage IV gastric cancer and treated with S-1 plus CDDP combination chemotherapy. After 4 courses of chemotherapy, the primary tumor and peritoneal dissemination were considered clinically stable, but the uterus grew rapidly. She was diagnosed as having uterine metastasis based on cervicaland endometrialsmear class V cytology...

BACKGROUND AND PURPOSE: Assessing the response to treatment in infiltrative brain tumors by using lesion volume-based response criteria is challenging. We hypothesized that in such tumors, volume measurements alone may not accurately capture changes in actual tumor burden during treatment. We longitudinally evaluated volume changes in both normal-appearing supratentorial white matter and the brain stem lesions in patients treated for diffuse intrinsic pontine glioma to determine to what extent adjuvant systemic therapies may skew the accuracy of tumor response assessments based on volumetric analysis...

BACKGROUND: Spinal epidural arteriovenous fistulas (SEDAVFs) are peculiar and poorly understood lesions with a poorly understood natural history. They are usually subclassified into two types according to their drainage components. This study aimed to describe a new type of SEDAVFs that is featured with a unique drainage pattern and present our natural history hypothesis of SEDAVFs. METHODS: Five SEDAVF cases of the new type were retrospectively reviewed from a high case-volume spinal vascular malformation database...

Fluorescein angiography (FA) is a useful test in patients affected by diabetic retinopathy (DR) to evaluate the blood-retinal barrier integrity and the presence of non-perfused areas, vascular leakage, microvascular abnormalities, and neovascularization. The peripheral retina is involved in most DR lesions, and, thus, its proper visualization is crucial for the screening, diagnosis, monitoring, treatment, and prognosis of DR. To expand the field of view, wide-field and ultra-wide-field imaging have been developed, allowing images up to 200° of retinal surface in one single photo...

Brain tumors represent a vast group of lesions, originating from different neuronal cells with different degrees of aggressiveness. Despite some technological advances either pre or post-treatment, these tumors may share similar imaging findings and properties, rendering diagnosis/prognosis, an ambiguous process. Gadolinium-enhanced magnetic resonance imaging remains the gold standard for providing detailed morphologic information, but presents several limitations due to the overlap of findings, in cases such as progressive tumor and post-radiation related effects...

Chemokines play a significant role in initial and advanced steps of atherogenesis. In early steps, chemokines control the adhesion of leukocytes to endothelial cells (ECs) followed by transmigration of monocytes and their deposition in the intima where they differentiate to proinflammatory macrophages. Except proinflammatory activity, chemokines are responsible for homeostasis and homing of progenitor cells. Recently, microRNAs (miRs) were found to control expression and activity of chemokines in ECs, vascular smooth muscle cells (VSMCs), and macrophages at different steps of atherogenesis...

Atherosclerosis is a chronic vascular disease in which atherosclerotic plaques develop in the arterial wall. It is believed that inflammation plays a major role in atherosclerotic formation and progression. Thus, atherosclerosis can be considered as an inflammatory disease of the arterial vessel. Mouse model demonstrated that T and B cell deficiency reduces the atherosclerotic burden in the formation of an atherosclerotic lesion. CD4+ T helper cells (Th), such as Th1 cells known being the major CD4+ T cell subtype found in mouse models of atherogenesis, increase plaque formation caused by oxLDL...

Focal nodular hyperplasia (FNH) is a common benign liver tumor, which occurs in the vast majority of the cases in young women. FNH represents a polyclonal lesion characterized by local vascular abnormalities and is a truly benign lesion without any potential for malignant transformation. A retrospective single institution analysis of 227 FNH patients, treated from 1990 to 2016 and a review of studies reporting surgical therapy of overall 293 patients with FNH was performed. Indications for resection with a focus on diagnostic workup, patient selection, surgical mode and operative mortality and morbidity have been analysed...
