Chronic psychological stress is one of the most important triggers and environmental risk factors for neuropsychiatric disorders. Chronic stress can influence all organs via the secretion of stress hormones, including glucocorticoids by the adrenal glands, which coordinate the stress response across the body. In the brain, glucocorticoid receptors (GR) are expressed by various cell types including microglia, which are its resident immune cells regulating stress-induced inflammatory processes. Read More

Evaluation of a new portable 1-lead digital cardiac monitor (eKuore) compared with standard base-apex electrocardiography in healthy horses.

PLoS One 2021 3;16(8):e0255247. Epub 2021 Aug 3.

Department of Veterinary Sciences, University of Pisa, San Piero a Grado, Pisa, Italy.

Recently, the use of smartphone ECG devices has been reported in humans and animals. Nevertheless, as the electrodes of these devices are inseparable, they can create only a precordial reading in veterinary species. Thus, although the smartphone ECG devices are considered valuable as a screening tool for the detection of some common arrhythmias, they are not always a reliable method for the measurement of the duration of the electrical deflections.

Background: Aortic arterial stiffness is a strong independent predictor of cardiovascular disease (CVD); however, its dependence on mean arterial pressure (MAP) limits its clinical utility. The aortic-femoral arterial stiffness gradient (af-SG), a novel marker of CVD risk, may be a promising alternative, but its dependence on MAP is not known. The aim of this study was to determine the relationship between MAP and the af-SG in healthy older adults and those with established disease, including hypertension and diabetes. Read More

J Hypertens 2021 Aug 2. Epub 2021 Aug 2.

Section of Geriatric Medicine, Department of Medicine Section of Geriatric Medicine, Department of Surgery, Dentistry, Pediatric and Gynecology, University of Verona, Verona, Italy.

Background: Orthostatic hypotension is an independent risk factor for cardiovascular morbidity and mortality. Arterial stiffness has been shown to be a pathophysiological mechanism linking orthostatic hypotension and increased cardiovascular risk. This study aims to evaluate the relationship between arterial stiffness, orthostatic hypotension and subendocardial viability ratio (SEVR) and moreover to identify the main predictors of orthostatic hypotension, carotid-femoral pulse wave velocity (PWV-cf) and SEVR.

Med Biol Eng Comput 2021 Aug 3. Epub 2021 Aug 3.

Faculty of Medicine, Department of Biophysics, Mersin University, 33110, Mersin, Turkey.

ECG-based differences between athletes and sedentary adolescents are a frequently investigated subject in sports medicine. Especially, training-induced ECG variations are common in adult athletes and sustained training often leads to anatomical changes in the heart that can yield abnormalities in ECG. Therefore, ECG screening in athletes is important in diagnosis of cardiac problems of young athletes. Read More

Risk factors for cytomegalovirus reactivation in patients with kidney disease under immunosuppressive therapy.

Clin Exp Nephrol 2021 Aug 3. Epub 2021 Aug 3.

Department of Nephrology, Tokyo Women's Medical University, Tokyo, 162-0054, Japan.

Background: Cytomegalovirus (CMV) is a herpes virus that causes latent infections, and its reactivation due to immunosuppression can cause fatal complications. CMV reactivation is a complication frequently occurring in patients with kidney disease who require immunosuppressive therapy, and, therefore, this study retrospectively examined its risk factors.

Methods: Patients who received immunosuppressive therapy and underwent the CMV antigenemia test (CMV antigenemia: C7-HRP) for the treatment of primary nephritis (minimal change disease, membranous nephropathy, membranoproliferative glomerulonephritis, focal glomerulosclerosis, and IgA nephropathy) and anti-neutrophil cytoplasmic autoantibody (ANCA)-associated nephritis diagnosed at Saiseikai Kurihashi Hospital from January 2014 to December 2019 were recruited as study participants.

Deep brain stimulation in patients on chronic antiplatelet or anticoagulation treatment.

Acta Neurochir (Wien) 2021 Aug 3. Epub 2021 Aug 3.

Department of Neurosurgery, Hannover Medical School, Carl-Neuberg-Straße 1, 30625, Hannover, Germany.

Background: In the aging society, many patients with movement disorders, pain syndromes, or psychiatric disorders who are candidates for deep brain stimulation (DBS) surgery suffer also from cardiovascular co-morbidities that require chronic antiplatelet or anticoagulation treatment. Because of a presumed increased risk of intracranial hemorrhage during or after surgery and limited knowledge about perioperative management, chronic antiplatelet or anticoagulation treatment often has been considered a relative contraindication for DBS. Here, we evaluate whether or not there is an increased risk for intracranial hemorrhage or thromboembolic complications in patients on chronic treatment (paused for surgery or bridged with subcutaneous heparin) as compared to those without.

Pediatr Cardiol 2021 Aug 3. Epub 2021 Aug 3.

CMR Unit, Royal Brompton and Harefield Hospital NHS Foundation Trust, Sydney Street, Chelsea, London, SW3 6NP, UK.

Neuromuscular diseases (NMD) encompass a broad spectrum of diseases with variable type of cardiac involvement and there is lack of clinical data on Cardiovascular Magnetic Resonance (CMR) phenotypes or even prognostic value of CMR in NMD. We explored the diagnostic and prognostic value of CMR in NMD-related cardiomyopathies. The study included retrospective analysis of a cohort of 111 patients with various forms of NMD; mitochondrial: n = 14, Friedreich's ataxia (FA): n = 27, myotonic dystrophy: n = 27, Becker/Duchenne's muscular dystrophy (BMD/DMD): n = 15, Duchenne's carriers: n = 6, other: n = 22.
