Coronary Artery Disease and Microvascular Ischemia in Patients with Cardiac Amyloidosis.

Introduction: The prevalence of preexisting obstructive coronary artery disease (CAD) and the occurrence of anginal chest pain as a presenting symptom in patients with light-chain (AL) and transthyretin (ATTR) cardiac amyloidosis (CA) are undetermined.

Methods: A single-center analysis of clinical, laboratory, imaging, and angiographic characteristics of CA cohort was performed.

Results: Included were 98 CA patients (43 AL, 47 wtATTR, 8 mutant ATTR).

Chronic Lymphocytic Leukemia (CLL)-Derived Extracellular Vesicles Educate Endothelial Cells to Become IL-6-Producing, CLL-Supportive Cells.

We hypothesized that via extracellular vesicles (EVs), chronic lymphocytic leukemia (CLL) cells turn endothelial cells into CLL-supportive cells. To test this, we treated vein-derived (HUVECs) and artery-derived (HAOECs) endothelial cells with EVs isolated from the peripheral blood of 45 treatment-naïve patients. Endothelial cells took up CLL-EVs in a dose- and time-dependent manner.

Noninvasive Hemodynamic Evaluation Following TAVI for Severe Aortic Stenosis.

Background Various hemodynamic changes occur following transcatheter aortic valve implantation (TAVI) that may impact therapeutic decisions. NICaS is a noninvasive bioimpedance monitoring system aimed at hemodynamic assessment. We used the NICaS system in patients with severe aortic stenosis (AS) to evaluate short-term hemodynamic changes after TAVI.

Ventricular Assist Devices: Challenges of the One-device Era.

Heart failure (HF) is linked to to high mortality rates and recurrent hospitalisations despite medical and device-based achievements. The use of left ventricular assist devices (LVADs) has improved survival among patients with advanced HF. Significant progress has been achieved with the new generation of continuous-flow devices, particularly with the fully magnetically levitated HeartMate 3.

[THE HISTORY OF THE ISRAELI YEARLY NEURO-OPHTHALMOLOGY MEETING - 25TH ANNIVERSARY].

This paper describes the difficulties to create a new Israeli annual meeting, 25 years ago, with the annual participation of the world's best neuro-ophthalmologists. This meeting contributed to the increase in the number of neuro-ophthalmologists in Israel, improved local knowledge, as well as the scientific research in this particular field, and changed the status of the Israeli neuro-ophthalmology on the international neuro-ophthalmology map.

Cancer-associated venous thromboembolism in Israel: Incidence, risk factors, treatment, and health care utilization in a population based cohort study.

Background: Recent international guidelines recommend thromboprophylaxis in patients with cancer at intermediate-high venous thromboembolism (VTE) risk.

Objectives: We aimed to assess the current incidence, risk factors and management of cancer-associated VTE and associated health care resource utilization in a 2.5-million-member state-mandated health service in Israel.

Leptin modulates gene expression in the heart, cardiomyocytes and the adipose tissue thus mitigating LPS-induced damage.

Leptin is an adipokine of pleiotropic effects linked to energy metabolism, satiety, the immune response, and cardioprotection. We have recently shown that leptin causally conferred resistance to myocardial infarction-induced damage in transgenic αMUPA mice overexpressing leptin compared to their wild type (WT) ancestral mice FVB/N. Prompted by these findings, we have investigated here if leptin can counteract the inflammatory response triggered after LPS administration in tissues in vivo and in cardiomyocytes in culture.

Retroperitoneal involvement with light chain amyloidosis- case series and literature review.

Retroperitoneal involvement is rare in patients with light chain (AL) amyloidosis and has only been published as case reports. Only 5 cases of retroperitoneal deposition have previously been reported in the setting of systemic AL amyloidosis. Data regarding the characteristics and clinical course of these patients are scarce.

When to Suspect a Diagnosis of Amyloidosis.

Amyloidosis is a group of complex diseases caused by extracellular deposition of pathological insoluble fibrillary protein in organs and tissues and may result in severe organ dysfunction. Despite the etiological heterogeneity of systemic amyloidosis, the clinical manifestations of the different forms of amyloidosis largely overlap and depend upon the effected organ. The signs and symptoms that should raise suspicion for the potential diagnosis of amyloidosis are usually nonspecific; therefore, establishing the diagnosis is difficult, and early diagnosis requires clinical suspicion.

Temporal Trends Analysis of the Characteristics, Management, and Outcomes of Women With Acute Coronary Syndrome (ACS): ACS Israeli Survey Registry 2000-2016.

Background Cardiovascular disease remains a leading cause of death among women. Despite improvements in the management of patients with acute coronary syndrome (ACS), women with an ACS remain at higher risk. Methods and Results We performed a time-dependent analysis of the management and outcomes of women admitted with ACS who enrolled in the prospective biennial ACS Israeli Surveys between 2000 and 2016.

The Effects of Proteasome Inhibitors on Telomerase Activity and Regulation in Multiple Myeloma Cells.

The importance of telomerase, the enzyme that maintains telomere length, has been reported in many malignancies in general and in multiple myeloma (MM) in particular. Proteasome inhibitors are clinically used to combat effectively MM. Since the mechanism of action of proteasome inhibitors has not been fully described we sought to clarify its potential effect on telomerase activity (TA) in MM cells.

Venetoclax for the treatment of multiple myeloma.

: Treatment of multiple myeloma (MM) in the relapsed setting remains challenging, despite recent impressive advances in the management of these patients. Venetoclax (ABT-199) is a BCL-2 inhibitor recently approved by the US food and drug administration for treatment of chronic lymphocytic leukemia but the drug has shown activity in a number of hematological malignancies. Venetoclax has broadened the treatment options for patients with relapsed or refractory MM.

Guideline-Recommended Therapies and Clinical Outcomes According to the Risk for Recurrent Cardiovascular Events After an Acute Coronary Syndrome.

Background Patients who have had an acute coronary syndrome ( ACS ) are at increased risk of recurrent cardiovascular events; however, paradoxically, high-risk patients who may derive the greatest benefit from guideline-recommended therapies are often undertreated. The aim of our study was to examine the management, clinical outcomes, and temporal trends of patients after ACS stratified by the Thrombolysis in Myocardial Infarction (TIMI) risk score for secondary prevention, a recently validated clinical tool that incorporates 9 clinical risk factors. Methods and Results Included were patients with ACS enrolled in the biennial Acute Coronary Syndrome Israeli Surveys ( ACSIS ) between 2008 and 2016.

[SCIENTIFIC PUBLICATIONS: ON HONORS AND GHOSTS].

The ethics committee at the Sackler Faculty of Medicine, Tel Aviv University deals with complaints which are not necessarily related to teaching or to issues in the realm of the Institutional Review Board (Helsinki Commission). Virtually all complaints reaching the committee are based on disputed authorship of scientific publications. Researchers and clinicians are interested in publishing their research in order to share knowledge but also in order to comply with the dictum "Publish or Perish".

Adult pre B-cell acute lymphoblastic leukemia with unusually large proportion of bone marrow CD45 bright/high SSc blasts.

Background: We present a pre B-ALL patient with the rare clinical manifestation of extramedullary disease, and a normal hemogram. This patient's blasts expressed bright CD45 and high side scatter (SSc) placing the cells in the monocyte gate.

Methods: Samples from peripheral blood and bone marrow (BM) aspirate from a 50-year-old female patient were immunophenotyped by multiparametric flow cytometry.

Stent graft closure of a high flow splenorenal shunt after liver transplantation.

We describe a patient after liver transplantation with a preexisting surgical splenorenal shunt close to the confluence of the splenic and superior mesenteric veins and a wide, short communication between the splenic and renal veins. To close the shunt, an inferior vena cava filter was inserted in the shunt and a vascular plug was placed in the splenic vein inside the filter. When this failed to stop the flow through the shunt, a covered stent was deployed at the superior mesenteric vein-portal vein junction.
