Clinical studies demonstrated a positive correlation between hypertension and cognitive decline. Beneficial effects of angiotensin II receptor blockers on cognitive functions have also been reported earlier; however, its role in chronic neuroinflammation-induced memory impairment in the hypertensive state is not well understood. Therefore, in the present study, we investigated the effect of angiotensin II receptor blockers on memory impairment induced by lipopolysaccharide (LPS) in spontaneously hypertensive rats (SHRs)...

BACKGROUND AND AIMS: Carvedilol, a non-selective beta-blocker (NSBB) with additional anti-alpha 1 receptor activity, is a potent portal hypotensive agent. It has been used as prophylaxis against variceal bleed. However, its safety in decompensated liver cirrhosis with ascites is still disputed. In this study, we examined whether long-term use of carvedilol in the presence of ascites is a risk factor for mortality. METHODS: This was a single-centre retrospective analysis of 325 consecutive patients with liver cirrhosis and ascites presenting to our Liver Unit between 1(st) of January 2009 to 31(st) August 2012...

RATIONALE: Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Emphysema on computed tomography (CT) is associated with increased morbidity and mortality in patients with and without spirometrically defined COPD but no available medications target emphysema.  Transforming growth factor beta (TGF-β) and endothelial dysfunction are implicated in emphysema pathogenesis, and angiotensin II receptor blockers (ARB) inhibit TGF-β, improve endothelial function and restore airspace architecture in murine models...

REVIEW
Randall P Sharp, Barry J Gales
Erectile dysfunction (ED) impacts over 100 million men worldwide and occurs at a higher incidence in men with hypertension. Beta blockers are one of several antihypertensive drug classes associated with ED. Nebivolol is a beta blocker with vasodilating properties mediated through endothelial release of nitric oxide which facilitates penile erection. Thus, nebivolol may offer an advantage over other beta blockers in the patient with hypertension and ED. A literature search comparing nebivolol with other beta blockers identified four European studies of limited duration, with the longest study being 28 weeks...

Congenital melanocytic nevi (CMN) are hamartomas present at birth that are composed of nevomelanocytes and thought to originate from faulty migration of precursor melanocytes in the neural crest. Classification is based on projected adult size of the lesion. CMN size correlates positively with risk of melanoma and neurocutaneous melanocytosis. Management requires a patient-centered approach that weighs the risks and benefits of and alternatives to complete removal. All children with large and giant CMN, regardless of surgical status, should be monitored closely and undergo periodic skin examination...

BACKGROUND: Many patients fail to receive β-blockers before cardiac resynchronization therapy defibrillator (CRT-D) implantation, or receive them at a suboptimal dose, and require optimization after implantation. We assessed the effectiveness of a structured program for β-blocker titration in CRT-D patients followed up by means of conventional in-clinic visits or remote monitoring. METHODS AND RESULTS: 130 patients undergoing CRT implantation and treated according to the standard practice of the centers were included as a control group...

Non-selective beta-blockers have played an important role in the prevention of portal hypertensive bleeding in cirrhotic patients. However, recent studies have suggested that non-selective beta-blockers may be harmful in some patients with end-stage liver disease. To evaluate the association between use of non-selective beta-blocker and the incidence of acute kidney injury (AKI). We conducted a nested case-control study in a cohort of liver transplant waitlist registrants. Each patient with AKI was matched to a control by the model for end-stage liver disease (MELD)-Na score, age, serum creatinine, and follow-up duration...

Sedative-hypnotic drugs include gamma-Aminobutyric acid (GABA)ergic agents such as benzodiazepines, barbiturates, gamma-Hydroxybutyric acid [GHB], gamma-Butyrolactone [GBL], baclofen, and ethanol. Chronic use of these substances can cause tolerance, and abrupt cessation or a reduction in the quantity of the drug can precipitate a life-threatening withdrawal syndrome. Benzodiazepines, phenobarbital, propofol, and other GABA agonists or analogues can effectively control symptoms of withdrawal from GABAergic agents...

Guson Kang, Dipanjan Banerjee
Mortality from heart failure remains high despite advances in medical therapy over the last three decades. Angiotensin receptor-neprilysin inhibitor (ARNI) combinations are the latest addition to the heart failure medical armamentarium, which is built on the cornerstone regimen of beta blockers, angiotensin converting enzyme (ACE) inhibitors/angiotensin receptor blockers, and aldosterone antagonists. Recent trial data have shown a significant mortality benefit from ARNIs, which, as of May 2016, have now received a class I recommendation for use in patients with heart failure and reduced ejection fraction from the major American and European cardiology societies...

Anthracycline chemotherapy maintains a prominent role in treating many forms of cancer. Cardiotoxic side effects limit their dosing and improved cancer outcomes expose the cancer survivor to increased cardiovascular morbidity and mortality. The basic mechanisms of cardiotoxicity may involve direct pathways for reactive oxygen species generation and topoisomerase 2 as well as other indirect pathways. Cardioprotective treatments are few and those that have been examined include renin angiotensin system blockade, beta blockers, or the iron chelator dexrazoxane...

Background -Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) occurs in 5-10% of all patients with MI. Clinical trials of secondary prevention treatment in MINOCA patients are lacking. Therefore, the aim of this study was to examine the associations between treatment with statins, renin-angiotensin system blockers, beta-blockers, dual antiplatelet therapy and long-term cardiovascular events. Methods -Observational study of MINOCA patients recorded in the SWEDEHEART registry between July 2003 and June 2013 and followed until December 2013 for outcome events in the Swedish Cause of Death Register and National Patient Register...

Thrombospondin-1 (TSP-1) is a potent endogenous inhibitor of both physiological and pathological angiogenesis, widely studied as a target in drug development for treating cancer. Several studies performed in the cardiovascular field on TSP-1 are contradictory, the role of TSP-1 in the physiopathology of cardiovascular disorders (CVDs) being, for the moment, incompletely understood and may be due to the presence of several domains in its structure which can stimulate many cellular receptors. It has been reported to inhibit NO-mediated signaling and to act on the angiogenesis, tissue perfusion, endothelial cell proliferation, and homeostasis, so we aimed to quantify the effect Perindopril has on TSP-1 plasma levels in hypertensive patients with endothelial dysfunction in comparison with other antihypertensive drugs, such as beta blockers, calcium channel blockers, and diuretics, in a chronic treatment...

The β1-adrenergic receptor (β1AR) is a G protein-coupled receptor (GPCR) and the predominant adrenergic receptor subtype in the heart, where it mediates cardiac contractility and the force of contraction. Although it is the most important target for β-adrenergic antagonists, such as beta-blockers, relatively little is still known about its regulation. We have previously shown that β1AR undergoes constitutive and regulated N-terminal cleavage participating in receptor down-regulation, and moreover that the receptor is modified by O-glycosylation...

OBJECTIVES/HYPOTHESIS: Local anesthetic with epinephrine is commonly injected into the nasal mucosa during functional endoscopic sinus surgery (FESS). Systemic absorption of epinephrine following local injection may occur, resulting in a mild sympathetic response. This study seeks to determine whether an exaggerated sympathetic response to epinephrine is demonstrated in patients undergoing FESS treated preoperatively with established pharmacologic beta (β) adrenoceptor blockade. STUDY DESIGN: A retrospective analysis of adult patients undergoing FESS at a tertiary care university hospital...
