Cardiomyopathies are a significant contributor to cardiovascular morbidity and mortality, mainly due to the development of heart failure and increased risk of sudden cardiac death (SCD). Despite improvement in survival with contemporary treatment, SCD remains an important cause of mortality in cardiomyopathies. It occurs at a rate ranging between 0.

Background Cancer is associated with an increased risk of acute ischemic stroke, including large vessel occlusions. Whether cancer status affects outcomes in patients with large vessel occlusions that undergo endovascular thrombectomy remains unknown. Methods and Results All consecutive patients undergoing endovascular thrombectomy for large vessel occlusions were recruited into a prospective ongoing multicenter database, and the data were retrospectively analyzed.

Having a beard is an independent predictor of difficult ventilation by face mask. This study evaluates the efficacy of a novel intra-oral Bag-Valve-Guedel Adaptor (BVGA) in anaesthetized bearded patients. Patients with ASA score 1-2, scheduled for elective surgery, were recruited for this prospective, crossover trial.

Article Synopsis
  • Malnutrition is prevalent in patients undergoing transcatheter edge-to-edge mitral valve repair (TEER), with 74.4% showing some level of malnutrition, but only 20% classified as moderate-severe.
  • In a study of 892 patients from the MIVNUT registry, moderate-severe malnutrition was found to significantly increase the risk of mortality (hazard ratio of 2.1) and heart failure admissions (subdistribution hazard ratio of 1.6) during a follow-up period averaging 1.6 years.
  • The findings suggest that evaluating nutritional status in patients undergoing TEER could enhance risk assessment and potentially improve patient outcomes.

Article Synopsis
  • - The study introduces EV-CATCHER, a specialized purification technique for selectively isolating small extracellular vesicles (EVs) containing nucleic acids, which can serve as biomarkers for diseases.
  • - EV-CATCHER was validated by isolating and sequencing small RNAs from mouse small-EVs in human plasma, demonstrating its effectiveness through various analytical methods.
  • - The technique was further applied to Covid-19 patient samples, revealing specific microRNAs that were significantly associated with disease severity, and confirming the neutralizing effects of certain EVs against SARS-CoV-2.

Background The cardiac ryanodine receptor type 2 (RyR2) is a large homotetramer, located in the sarcoplasmic reticulum (SR), which releases Ca from the SR during systole. The molecular mechanism underlying Ca sensing and gating of the RyR2 channel in health and disease is only partially elucidated. Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT1) is the most prevalent syndrome caused by RyR2 mutations.

Clinical Course and Outcomes of Severe Covid-19: A National Scale Study.

J Clin Med

July 2020

Israel Defense Forces, Medical Corps, Tel Hasomer, Ramat Gan 01215, Israel.

Unlabelled: Knowledge of the outcomes of critically ill patients is crucial for health and government officials who are planning how to address local outbreaks. The factors associated with outcomes of critically ill patients with coronavirus disease 2019 (Covid-19) who required treatment in an intensive care unit (ICU) are yet to be determined.

Methods: This was a retrospective registry-based case series of patients with laboratory-confirmed SARS-CoV-2 who were referred for ICU admission and treated in the ICUs of the 13 participating centers in Israel between 5 March and 27 April 2020.

Importance: The neuronal mechanism of visual agnosia and foveal crowding that underlies the behavioral symptoms of several classic neurodegenerative diseases, including impaired holistic perception, navigation, and reading, is still unclear. A better understanding of this mechanism is expected to lead to better treatment and rehabilitation.

Objective: To use state-of-the-art neuroimaging protocols to assess a hypothesis that abnormal population receptive fields (pRF) in the visual cortex underlie high-order visual impairments.

Inhibition of histone deacetylases (HDACs) and subsequent hyperacetylation of histone proteins lead to altered gene expression associated with therapeutic drug effects, but also with teratogenicity. The only US Food and Drug Administration (FDA)-approved antiepileptic drug that has been consistently shown to induce histone hyperacetylation is valproic acid. More recently, lacosamide was reported to interfere with histone modifications, but histone hyperacetylation was not demonstrated.

Purpose: The neural substrate of binocularity and sighting ocular dominance in humans is not clear. By utilizing the population receptive field (pRF) modeling technique, we explored whether these phenomena are associated with amplitude and pRF size differences.

Methods: The visual field maps of 13 subjects were scanned (3-T Skyra) while viewing drifting bar stimuli.

Insulin resistance is a key risk factor in the progression of nonalcoholic fatty liver disease (NAFLD) and may lead to liver fibrosis. Natural killer (NK) cells are thought to exert an antifibrotic effect through their killing of activated hepatic stellate cells (HSCs). Here, we investigated how the interplay between NK cells and HSCs are modified by insulin resistance in NAFLD.

Background: Evidence for the effects of Parkinson disease on energy expenditure is incomplete and contradictory. A number of studies showed increased resting energy expenditure among patients with Parkinson disease whereas others did not. It was hypothesized that energy expenditure increases during exercise, based on findings in patients with a variable regime of anti-parkinsonian therapies and at different stages of the disease.

Metabolic Stress and Compromised Identity of Pancreatic Beta Cells.

Front Genet

February 2017

Department of Developmental Biology and Cancer Research, The Institute for Medical Research Israel-Canada, The Hebrew University-Hadassah Medical School Jerusalem, Israel.

Beta cell failure is a central feature of type 2 diabetes (T2D), but the molecular underpinnings of the process remain only partly understood. It has been suggested that beta cell failure in T2D involves massive cell death. Other studies ascribe beta cell failure to cell exhaustion, due to chronic oxidative or endoplasmic reticulum stress leading to cellular dysfunction.

Neurodegenerative diseases present pathologically with progressive structural destruction of neurons and accumulation of mis-folded proteins specific for each condition leading to brain atrophy and functional disability. Many animal models exert deposition of pathogenic proteins without an accompanying neurodegeneration pattern. The lack of a comprehensive model hinders efforts to develop treatment.

There is currently minimal clinical experience regarding retreatment options for patients failing direct-acting antiviral combination regimens. Here, we report the outcomes of a HCV genotype 1b-infected patient with virologic failure following treatment with daclatasvir and asunaprevir, who was successfully retreated with sofosbuvir plus simeprevir.

We present a case of left renal colic in a 25-year-old female patient. She had subureteral injection of Teflon (STING) at the age of 10 due to vesico-ureteral reflux (VUR) disease and recurrent urinary tract infections. Renal colic was the result of late ureteral obstruction due to Teflon-induced periureteral foreign body reaction.
