Macrovascular invasion

Cheng Chen, Janet Wei, Ahmed AlBadri, Parham Zarrini, C Noel Bairey Merz
Angina has traditionally been thought to be caused by obstructive coronary artery disease (CAD). However, a substantial number of patients with angina are found to not have obstructive CAD when undergoing coronary angiography. A significant proportion of these patients have coronary microvascular dysfunction (CMD), characterized by heightened sensitivity to vasoconstrictor stimuli and limited microvascular vasodilator capacity. With the advent of non-invasive and invasive techniques, the coronary microvasculature has been more extensively studied in the past 2 decades...

AIMS/HYPOTHESIS: Gestational diabetes mellitus (GDM) is a risk factor for the development of endothelial dysfunction and cardiovascular disease. However, in vivo microvascular endothelial function in GDM has not been investigated. This study aimed to examine, using near-infrared spectroscopy (NIRS), whether: (1) there are differences in microvascular reactivity and skeletal muscle oxygen consumption (m[Formula: see text]) at rest and during exercise between GDM and uncomplicated pregnancies; and (2) there is an association of NIRS indices with macrovascular function and cardiovascular disease risk factors...

Importance: Serum α-fetoprotein (AFP) is a biomarker for hepatocellular carcinomas (HCCs) associated with a more aggressive tumor phenotype and inferior outcomes after a liver transplant (LT). Data on the outcomes for patients with HCCs that do not produce AFP are limited. Objective: To compare characteristics and outcomes among LT recipients with radiographically apparent HCC lesions with AFP-producing tumors or with tumors that do not produce AFP (hereafter referred to as non-AFP-producing tumors), and to identify factors influencing recurrence in LT recipients with non-AFP-producing tumors...

The global prevalence of diabetes mellitus is increasing; arguably as a consequence of changes in diet, lifestyle and the trend towards urbanization. Unsurprisingly, the incidence of both micro and macrovascular complications of diabetes mirrors this increasing prevalence. Amongst the complications with the highest symptom burden, yet frequently under-diagnosed and sub-optimally treated, is diabetic autonomic neuropathy, itself potentially resulting in cardiovascular autonomic neuropathy and gastrointestinal (GI) tract dysmotility...

OBJECTIVE: Cardiopulmonary manifestations have an important impact on the life expectancy of SSc patients. Functional and morphological macrovascular changes may appear early before the development of ischaemic symptoms. Several non-invasive methods are used in cardiovascular risk assessment. Heterogeneous data are available regarding these in SSc. We aimed to perform a systematic review and meta-analysis to characterize the importance of atherosclerosis in SSc. METHODS: A systematic literature search was performed to identify controlled studies on carotid intima-media thickness, flow- or nitrate-induced vasodilatation (flow-mediated dilatation, nitroglycerine-mediated dilatation), pulse wave velocity, augmentation index and ankle-brachial pressure index...

OBJECTIVE: Patients with Gestational diabetes mellitus (GDM) are at increased risk for gestational hypertension. Although GDM is considered a mild metabolic dysfunction, some studies have associated GDM with alterations of endothelial responsiveness, whereas, other studies suggested that the time of exposure to hyperglycemia might be insufficient to induce micro- and macrovascular dysfunction. Near-infrared spectroscopy (NIRS) allows a non-invasive monitoring of functional changes in oxygenated hemoglobin (O2Hb) and oxygen tissue saturation (TSI) and the assessment of microvascular function within the skeletal muscle...

: The prognosis of hepatocellular carcinoma (HCC) remains poor, with only one third of patients eligible for curative treatments and very limited survival benefits with the use of sorafenib, the current standard of care for advanced disease. Recently, agents targeting the programmed death ligand 1 (PD-L1)/programmed death receptor 1 (PD-1) immune checkpoint were shown to display impressive antitumor activity in various solid or hematological malignancies, including HCC. PD-L1 immunohistochemical expression is thought to represent a biomarker predictive of drug sensitivity...

BACKGROUND: Recurrence of hepatocellular carcinoma (HCC) in patients treated with liver transplantation (LT) is associated with diminished survival. Particularly, extrahepatic localization of HCC recurrence contributes to poor prognosis. PATIENTS AND METHODS: Clinicopathological data of patients who underwent LT for HCC between 1989 and 2010 in a high-volume transplant center were retrospectively evaluated, and predictors of extrahepatic recurrence were identified...

Several studies have shown that advanced glycation end products (AGE) play a role in both the microvascular and macrovascular complications of diabetes and are closely linked to inflammation and atherosclerosis. AGEs accumulate in skin and can be detected using their auto fluorescence (AF). A significant correlation exists between AGE AF and the levels of AGEs as obtained from skin biopsies. A commercial device, the AGE Reader, has become available to assess skin AF for clinical purposes but, while displaying promising results, it is limited to single-point measurements performed in contact to skin tissue...

BACKGROUND: The prevalence of macrovascular complications is probably underestimated in children with type 1 diabetes (T1D). Arterial stiffness (AS) is a subclinical marker of cardiovascular (CV) risk. The most validated, non-invasive method for AS measurement is pulse wave velocity (PWV). Only a few PWV studies have been performed in children with T1D. OBJECTIVE: To explore the risk factors associated with AS in adolescents with suboptimally controlled T1D. PATIENTS AND METHODS: Seventy-seven adolescents with T1D were included (39 girls, 38 boys) in this study...

PURPOSE OF REVIEW: Complete surgical resection is the only curative-intent therapy for patients with hilar cholangiocarcinoma, and obtaining negative pathologic margins is crucial to allow for prolonged disease-free survival. Macrovascular tumor invasion adds technical complexity to surgical extirpation, but can be achieved with en bloc vessel resection. This tumor extension adversely affects overall prognosis, but is nonetheless technically feasible. RECENT FINDINGS: Several recent meta-analyses have studied the short and long-term results of concomitant vascular resection during surgery for hilar cholangiocarcinoma...

Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified...
