Background: Acute coronary syndrome (ACS) represents a spectrum of ischemic myocardial disease including unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). Various prognostic scores were developed for patients presenting with NSTEMI-ACS. Among these scores, the GRACE risk score offers the best discriminative performance for prediction of in-hospital and 6-month mortality. However, the GRACE score is limited and cannot be used in several ethnic populations. Moreover, it is not predictive of clinical outcomes other than mortality.

Objective: To assess the prognostic value of traditional cardiovascular risk factors and laboratory biomarkers in predicting 6-month major adverse cardiac and cerebrovascular events (MACCE), including hospitalization, recurrent percutaneous coronary intervention (PCI), stroke, and cardiovascular mortality in patients with NSTEMI treated with PCI.

Methods: This retrospective study included consecutive patients admitted with an initial diagnosis of NSTEMI to the cardiac intensive care unit (CICU) at the Tzafon Medical Center, Israel, between April 2015 and August 2018 and treated by PCI within 48 hours of admission.

Results: A total of 223 consecutive patients with NSTEMI treated by PCI were included in the study. Logarithmebrain natriuretic peptide (LogₑBNP), prior MI, and Hb levels were found to be significant predictors of any first MACCE. Only logₑBNP was found to be an independent predictor of a first MACCE event by multivariate logistic regression analysis.

Conclusions: LogₑBNP is an independent predictor of worse prognosis in patients with NSTEMI. Routine evaluation of BNP levels should be considered in patients admitted with NSTEMI.

The interplay between post-traumatic stress disorder (PTSD) and autoimmunity is well known. One of the contributors leading to immune disorders is autonomic dysregulation, which is characterized by attenuated parasympathetic and elevated sympathetic systems. In this review, we described evidence regarding the relationship between stress, PTSD, autonomic dysfunction, and autoimmunity. Stress is a physiological response, which is functional for our being. The implication of dysfunction in stress response may be a cause of disease development. We described the fundamental role of the pathological high levels of stress in PTSD as a mediator factor that contributes to autonomic dysfunction, which as a result may lead to autoimmunity. Systemic lupus erythematosus, rheumatoid arthritis, and type 1 diabetes are some of the autoimmune diseases PTSD patients are at higher risk of developing. Notably, some autoimmune diseases are shown to increase the susceptibility to develop PTSD, which may indicate a bidirectional influence. In addition, we elaborated on stress as a major component in both fibromyalgia and PTSD, as there are overlaps between the pathogenesis of fibromyalgia and PTSD. Underlying chronic low-grade inflammation, which characterizes PTSD patients, may be a potential target and biomarker in treating PTSD patients. We believe that chronic low-grade inflammation, high concentrations of cytokines, and other inflammatory biomarkers, which characterize PTSD patients, may be potential targets and biomarkers in the treatment of PTSD patients and part of the PTSD diagnostic criteria.

Background: Changes accommodating requirements of religious authorities in Israel resulted in the Brain and Respiratory Death Determination Law (BRDDL), which came into effect in 2009. These included considering patient wishes regarding the brain respiratory death determination (BRDD), mandatory performance of apnea and ancillary testing, establishment of an accreditation committee, and accreditation required for physicians performing BRDD.

Objectives: To assess the impact of the legislation from 2010–2019.

Methods: Data collected included the number of formal BRDDs and accredited physicians. Obstacles to declaring brain death and interventions applied were identified.

Results: Obstacles included lack of trained physicians to perform BRDD and interpret ancillary test results, inability to perform apnea or ancillary testing, and non-approach to next-of-kin objecting to BRDD. Interventions included physician training courses, additional ancillary test options, and legal interpretation of patient wishes for non-determination of BRD. As a result, the number of non-determinations related to next-of-kin objecting decreased (26 in 2010 to 5 in 2019), inability to perform apnea or ancillary testing decreased (33 in 2010 to 2 in 2019), and number of physicians receiving accreditation increased (210 in 2010 to 456 in 2019). Last, the consent rate for organ donation increased from 49% to 60% in 2019.

Conclusions: The initial decrease in BRDDs has reversed, thus enabling more approaches for organ donation. The increased consent rate may reflect in part the support of the rabbinate and confidence of the general public that BRDD is performed and monitored according to strict criteria.

The connection between physical exercise and the brain has long been studied. The evidence showing that physical exercise plays a significant role on neurogenesis and cognitive function has primarily been based on research examining aerobic exercise. In this review, we described three exercise modalities: aerobic, anaerobic, and resistance exercise and their impact on brain plasticity and cognitive function. While each of these exercise modalities have been demonstrated to positively influence brain plasticity and cognitive function, the specific mechanism that stimulates these changes appear to differ to some degree between these training modalities. The effect of aerobic and anaerobic exercise appears to be primarily mediated by changes in expression of brain-derived neurotrophic factor (BDNF), lactate, vascular endothelial growth factor (VEGF), and several additional proteins within the brain. However, resistance exercise appears to influence brain plasticity by myokines such as irisin, insulin-growth factor-1 (IGF1), and BDNF that are secreted from skeletal tissue and stimulate neurogenesis within the brain. In addition to the various training modes, manipulation of various acute program variables such as intensity, volume, and rest intervals leads to numerous possible training paradigms that can provide a different stimulus for neurogenesis. This review focuses on the three primary training modes and their connection to neurogenesis and cognitive function.

Medical records discovered after the liberation of ghettos in Nazi-occupied Europe are unique documents that report on the suffering of inmates, on ravaging infectious diseases, and on starvation-related organ degeneration and the resulting mortality. We offer a pathogenetic explanation for the scarcity of acute myocardial infarction in the Lodz Ghetto, Poland, 1941–1944

Advances in Lymphoma management have resulted in significant improvements in patient outcomes over the last 50 years. Despite these developments, cardiotoxicity from lymphoma treatments remains an important cause of mortality and morbidity in this cohort of patients. We outlined the most common cardiotoxicities associated with lymphoma treatments and their respective investigation and management strategies, including the role of cardiac pre-assessment and late effects monitoring.
