Hypereosinophilic syndrome is a rare disorder characterized by excessive peripheral eosinophilia and eosinophil associated end-organ damage. Clinical presentations are heterogenous and can involve skin, pulmonary, cardiac and neurologic dysfunction. ⋯ Secondary to changes in blood viscosity, impaired clearance of microemboli, impaired cerebral blood flow, and pro-thrombotic conditions in the setting of hypereosinophilia, infarcts often present in vascular border zone regions. Here we present two cases of cardioembolic strokes involving borderzone regions in the setting of hypereosinophilic syndrome.

Prediabetes versus type 2 diabetes in patients with acute myocardial infarction and current smoking.
Smoking is linked with increased risk of cardiovascular events among diabetic patients. Prediabetes is associated with increased risk for microvascular and macrovascular complications. We compared the 2-year clinical outcomes of current smoking between prediabetic and type 2 diabetes mellitus (T2DM) patients with acute myocardial infarction (AMI) after newer-generation drug-eluting stent (DES) implantation. ⋯ Current smoking leads to worse clinical outcomes in patients with AMI and prediabetes, and thus, similarly to T2DM patients, more attention and more intensive treatment strategy including quitting smoking would be advantageous.

In regards to breast cancer (BC), survival or disease-free periods are still compromised mainly in Triple Negative (TN) and HER2 tumors. The participation of estrogen receptor (ER) has been reported as crucial in the signaling pathways, including the NOTCH pathway. The study was aimed to evaluate the expression of NOTCH1 and NOTCH3 in BC and its relationship with the presence of ER, as well as with relapses. ⋯ NOTCH1 and NOTCH3 were found to be overexpressed mainly in ERN tumors. HER2 and TN groups, are related to higher relapse rates. Therefore, anti-NOTCH therapy could be justified and implemented in conventional treatments of high-risk BC groups.

The spectrum of kidney involvement in systemic sclerosis (SSc) includes scleroderma renal crisis, widely recognized as the most severe renal-vascular complication, but also several forms of chronic renal vasculopathy and reduced renal function are complications of scleroderma. Scleroderma renal crisis, myeloperoxidase-antineutrophil cytoplasmic antibody associated glomerulonephritis, penicillamine-associated renal disease, abnormal urinalysis, alteration of vascular endothelial markers, scleroderma associated-vasculopathy with abnormal renal resistance indices and cardiorenal syndromes type 5 were also reported in SSc patients. ⋯ Indeed, asymptomatic renal changes, expressed by increase of intrarenal stiffness, are often non-progressive in SSc patients but can lead to a reduction in renal functional reserve. The purpose of this review is to provide an assessment of kidney involvement in SSc, from SRC to subclinical renal vasculopathy.

The tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is one of the inflammatory mediators contributing to the atherosclerotic process. TWEAK has been studied in patients with chronic kidney disease (CKD), and it has demonstrated that its level declines as estimated glomerular filtration rate (eGFR) decreases. Most studies have found that the decreased TWEAK levels were seen in atherosclerosis and associated with plaque calcification. The objective of this prospective study was to clarify any relationship between coronary slow-flow (CSF) and TWEAK levels in patients with CKD under conservative treatment. ⋯ Our study has shown that plasma TWEAK levels were an independent predictor for CSF in patients with CKD. In addition, our study has found that elevated TWEAK levels may not reflect the healthy arteries as it was hypothesized in the past.
