Obstructive sleep apnea (OSA) is a prevalent sleep disorder as is hypertension (HTN) in the 21st century with the rising incidence of obesity. Numerous studies have shown a strong association of OSA with cardiovascular morbidity and mortality. There is overwhelming evidence supporting the relationship between OSA and hypertension (HTN). The pathophysiology of HTN in OSA is complex and dependent on various factors such as sympathetic tone, renin-angiotensin-aldosterone system, endothelial dysfunction, and altered baroreceptor reflexes...

Olivier Walusinski
Yawning, laughing, and crying are normal physiological behaviors of humans in good health. As with all physiological behaviors, their deregulation can reveal disorders. Pathological yawning occurs in salvos of 10-20 successive yawns, and the number of yawns per day can exceed one hundred. After listing the functional etiologies, we will give the clinical keys for differentiating the most serious causes: iatrogenic, tumors, strokes, amyotrophic lateral sclerosis, and intracranial hypertension. Sudden, uncontrollable episodes of emotional display involving pathological laughing and crying (PLC) may be encountered in various neurological diseases: amyotrophic lateral sclerosis, multiple system atrophy (cerebellar), cerebrovascular disease, traumatic brain injuries, mass lesions in the cerebellopontine junction, and epilepsy...

Gallic acid (GA) has been reported to have beneficial effects on cancer, vascular calcification, and diabetes-induced myocardial dysfunction. We hypothesized that GA controls hypertension via oxidative stress response regulation in an animal model for essential hypertension. Spontaneously hypertensive rats (SHRs) were administered GA for 16 weeks. GA treatment lowered elevated systolic blood pressure in SHRs through the inhibition of vascular contractility and components of the renin-angiotensin II system. In addition, GA administration reduced aortic wall thickness and body weight in SHRs...

BACKGROUND: The controversy over electrotherapy for patients aged >80 years occurs already at the stage of qualification for this treatment type and concerns optimal device selection, the implantation strategy, and the overall benefit from pacemaker therapy. The group also has a considerable number of cardiovascular risk factors, and the data from the literature on the impact of the pacing mode on the remote prognosis of this group are ambiguous. OBJECTIVE: Assessment of the risk factors for death among patients with implanted pacemakers >80 years of age in a 4-year follow-up...

Activation of baroreceptors in the carotid modulates the autonomic nervous system. Baroreflex activation therapy (BAT), which activates baroreceptors in the carotid, has become available in the treatment of resistant hypertension. Besides this, a carotid implant modulating baroreceptors as well as pharmacological modulation of carotid bodies were quite recently presented. This review will underscore currently available and promising approaches that activate baroreceptors in the carotid, and thereby contribute to beneficial effects in patients with arterial hypertension, and discusses potential organoprotective BAT effects beyond blood pressure (BP) reduction...

The calcineurin inhibitor cyclosporine A (CsA) suppresses the immune system but promotes hypertension, vascular dysfunction, and renal damage. CsA decreases regulatory T cells and this contributes to the development of hypertension. However, CsA's effects on another important regulatory immune cell subset, myeloid-derived suppressor cells (MDSCs), is unknown. We hypothesized that augmenting MDSCs would ameliorate the CsA-induced hypertension and vascular and renal injury and dysfunction and that CsA reduces MDSCs in mice...

Hypertension is a well-documented predictive factor for cardiovascular events. Clinical studies have extensively demonstrated the differential hemodynamic consequences of various anti-hypertensive drugs, but failed to clearly elucidate the underlying mechanisms due to the difficulty in performing a quantitative deterministic analysis based on clinical data that carry confounding information stemming from inter-patient differences and the nonlinearity of cardiovascular hemodynamics. In the present study, a multi-scale model of the cardiovascular system was developed to quantitatively investigate the relationships between hemodynamic variables and cardiovascular properties under hypertensive conditions, aiming to establish a theoretical basis for assisting in the interpretation of clinical observations or optimization of therapy...

Post-transplant hypertension is a common occurrence during treatment with calcineurin inhibitors (CNIs) in kidney transplant population. The pathogenesis of vasoconstriction induced by CNIs involves vascular tone alterations and kidney sodium transport regulation. Among the factors involved a key role is played by the activation of intrarenal renin-angiotensin system with enhanced release of Angiotensin II (Ang II) and increase of oxidative stress. A common pathway between oxidative stress and hypertension induced by CNIs may be identified in the involvement of the activation of RhoA/Rho kinase pathway, key for the induction of hypertension and cardiovascular-renal remodeling, of the oxidative stress mediated increased nitric oxide (NO) metabolism and increased renal sodium retention via increased activity of thiazide-sensitive sodium chloride cotransporter (NCC) in the distal tubule...

Effective interventions to identify and treat uncontrolled hypertension (HTN), particularly in underrepresented populations that use the emergency department (ED) for primary care, are critically needed. Uncontrolled HTN contributes significantly to cardiovascular morbidity and mortality and is more frequently encountered among patients presenting to the ED as compared to the primary care setting. EDs serve as the point of entry into the health care system for high-risk patient populations, including minority and low-income patients...

Until recently progression of diabetic kidney disease could have been slowed down only by the inhibition of the renin-angiotensin system. Inhibitors of SGLT2 (sodium-glucose transporter 2) in the proximal tubulus of the kidney induce natriuresis and by the activation of the tubuloglomerular feedback increase the tone of the afferent arteriole and decrease the glomerular pressure. Empagliflozin in the study EMPA-REG Outcome significantly decreased the risk of progression of diabetic kidney disease and further analyses also demonstrated its potent antiproteinuric effect...

Hypertension is associated with endothelial dysfunction, which favors the release of endothelium-derived contracting factors, including vasoconstrictor prostanoids and reactive oxygen species. Peroxisome proliferator-activated receptor α (PPARα) agonists, clinically used as lipid lowering drugs, possess antioxidant properties and exert beneficial effects in the vascular system. The present study aimed to identify the mechanism(s) underlying the acute effects of the PPARα agonists, Wy14643 and fenofibate, on endothelium-dependent contractions, in particular, those related to oxidative stress, in the aorta of the spontaneously hypertensive rat (SHR)...
