The pharmacological treatment for stable COPD is based on the use of inhaled bronchodilators (long-acting muscarinic receptor antagonists and long-acting beta-2 adrenoceptor agonists) and inhaled corticosteroids. The use of triple inhaled therapy is recommended to selected patients with COPD. Among the various inhaler combinations in triple therapy, a new combination by fluticasone furoate, umeclidinium, and vilanterol is available for COPD patients. Recently, a large clinical trial using this combination has been published, resulting in a reduction in exacerbation rate in COPD patients...

INTRODUCTION: Overactive bladder syndrome (OAB) is a highly prevalent and costly condition worldwide with negative impact on health-related quality of life. Although many guidelines exist and anticholinergics are considered to be the mainstay of pharmacological treatment, data are lacking regarding optimal treatment duration. Therefore, the aim of this study was to determine practice patterns of Canadian urologists and gynecologists regarding duration of OAB pharmacotherapy. METHODS: A 14-question survey was designed and survey links (English and French) were sent by email to all practicing urologists and gynecologists registered with the Canadian Urological Association and the Society of Obstetricians and Gynecologists of Canada via the associations' email lists...

INTRODUCTION: Due to a high prevalence of asthma and exercise-induced bronchoconstriction in elite athletes, there is a high use of beta2 -adrenoceptor agonists (beta2 -agonists) in the athletic population. While anabolic in rodents, no study has been able to detect hypertrophy in humans after chronic beta2 -agonist inhalation. METHODS: We investigated if inhaled beta2 -agonist, terbutaline, alters body composition and metabolic rate with and without concurrent exercise training in healthy young men...

Background: Sphingolipids are versatile signaling molecules derived from membrane lipids of eukaryotic cells. Ceramides regulate cellular processes such as proliferation, differentiation and apoptosis and are involved in cellular stress responses. Experimental evidence suggests a pivotal role of sphingolipids in the pathogenesis of cardiovascular diseases, including ischemic stroke. A neuroprotective effect has been shown for beta-adrenergic antagonists in rodent stroke models and supported by observational clinical data...

Patients suffering from chronic heart failure (CHF) caused or promoted by autoantibodies against cardiac beta1 -adrenergic receptors (beta1 AR) could benefit from specific therapies aimed at tolerance induction, removal or neutralisation of beta1 AR autoantibodies, provided the patients can be selected for these therapies by reliable detection and quantitation of beta1 AR autoantibodies in their circulation and by a valid assessment of the autoantibodies's putative cardio-pathogenic potential. Here, we discuss the current state of knowledge regarding the effects of CHF-associated (auto)antibodies on beta1 AR function and beta1 AR-mediated signal tranduction and discuss the presumed role of these effects in the development and progression of CHF...

We appreciate the valuable comments from Drs. Abdelmaksoud and Vestita regarding our study about the in situ expression of vascular endothelial growth factor (VEGF) and endoglin in patients with pemphigus foliaceus (PF) and pemphigus vulgaris [1]. We proposed that the severity of PF is related not only to the level of circulating autoantibodies but also to the ability to restore tissue integrity following intraepidermal detachment. We have demonstrated that overexpression of VEGF is observed both in serum samples[2] and skin fragments obtained from patients with severe PF[3], and suggested the use of β-blockers to regulate it...

The objectives of this paper is to investigate, demonstrate, and compare the mechanism of action of phytocannabinoids as antidiabetic and anti-obesity agents in preadipocytes and adipocytes, relative to rosiglitazone and metformin. Briefly, cannabis extract, Δ9 -tetrahydrocannabinol and cannabidiol (in very low dosages) were shown to promote glucose uptake higher or to equivalent levels, reduce fat accumulation, and reverse the insulin-resistant state of 3T3-L1 cells more effectively, relative to rosiglitazone and metformin...

Inherited defects of the neuromuscular junction (NMJ) comprise an increasingly diverse range of disorders, termed congenital myasthenic syndromes (CMS). Therapies acting on the sympathetic nervous system, including the selective β2 adrenergic agonist salbutamol and the α and β adrenergic agonist ephedrine, have become standard treatment for several types of CMS. However, the mechanism of the therapeutic effect of sympathomimetics in these disorders is not understood. Here, we examined the effect of salbutamol on NMJ development using zebrafish with deficiency of the key postsynaptic proteins Dok-7 and MuSK...

BACKGROUND AND PURPOSE: Previous studies revealed that Takotsubo cardiomyopathy (TTC), a transient disorder of ventricular dysfunction affecting predominantly postmenopausal women, is associated with acquired long QT syndrome and arrhythmias, but the exact pathophysiologic mechanism is unknown. Our aim is to investigate the electrophysiological mechanism for QT-prolongation in TTC-patients by using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). METHODS: hiPSC-CMs, which were generated from human skin fibroblasts of three healthy donors, were treated by estradiol (10μM for one week) and a toxic concentration of isoprenaline (Iso, 1mM for 2h)...

Akathisia consists of subjective inner restlessness, such as awareness of the inability to remain seated, restless legs, fidgetiness, and the desire to move constantly, and of objective increased motor phenomena, such as body rocking, shifting from foot to foot, stamping in place, crossing and uncrossing legs, pacing around. Although the broad definition of akathisia includes the inner and motor restlessness observed in patients with idiopathic Parkinson's disease, post-encephalitic parkinsonism, and restless legs syndrome, here we exclusively focus on the narrow definition of antipsychotic-induced akathisia...

The central nervous system controls the innate immunity by modulating efferent neuronal networks. Recently, we have reported that central brain stimulation inhibits inflammatory responses. In the present study, we investigate whether spinal p38 mitogen-activated protein kinase (MAPK) affects joint inflammation in experimental arthritis. Firstly, we observed that intra-articular administration of zymosan in mice induces the phosphorylation of the spinal cord p38 MAPK. In addition, we demonstrated that spinal p38 MAPK inhibition with intrathecal injection of SB203580, a conventional and well-characterized inhibitor, prevents knee joint neutrophil recruitment, edema formation, experimental score and cytokine production...

AIMS: Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR) differ in their renin-angiotensin system function and sympathetic tone. The metabolism of angiotensins and vasopressin depends on the action of certain aminopeptidases whose activity may be influenced by the autonomic nervous system. Their regulation may differ between WKY and SHR in hypothalamus and plasma according to the sympathetic tone. We analyzed aminopeptidases responsible for the hydrolysis of certain angiotensins, vasopressin, cholecystokinin or enkephalins in hypothalamus and plasma of WKY and SHR in untreated controls rats and under beta-adrenoceptor blockade...

Widespread application of the plasma aldosterone/renin ratio (ARR) as a screening test has led to the recognition that primary aldosteronism (PA) is the most common specifically treatable and potentially curable form of hypertension, accounting for 5-10% of patients. Maximal detection requires accurate diagnostic approaches and awareness and control of factors that confound results, including most antihypertensives, posture, time of day, dietary salt, and plasma potassium. Recent studies have revealed potential for false positives in patients on beta-adrenoceptor blockers, and, when direct renin concentration (but not plasma renin activity) is used to measure renin, in women during the luteal phase of the menstrual cycle or receiving estrogen-containing contraceptives or hormonal replacement therapy...

BACKGROUND: The tricyclic antidepressant amitriptyline, the serotonin and noradrenaline reuptake inhibitor duloxetine, and gabapentinoids are first-line drugs for treatment of neuropathic pain. The analgesic effect of these drugs relates to brainstem-spinal descending noradrenergic systems. However, amitriptyline utilizes a variety of mechanisms for analgesia in neuropathic pain, and it is unclear which mechanism is most important. In the present study, we investigated the role of descending noradrenergic systems in the analgesic effect of these drugs for treatment of neuropathic pain...
