Orthostatic intolerance, one of the principle causes of syncope, can occur secondary to concomitant venous pooling and enhanced capillary filtration. We aimed to evaluate a prototype portable calf active compression brace (ACB) designed to improve orthostatic haemodynamic control. Fourteen healthy volunteers participated in a randomized, placebo controlled, cross-over, double-blind study. Testing consisted of head-upright tilting and walking on a treadmill conducted on two consecutive days with a pair of ACBs wrapped around both calves...

BACKGROUND: Hereditary haemorrhagic telangiectasia (HHT) remains a difficult disease for the ENT specialist to manage. Affected patients often report recurrent epistaxis as the most debilitating symptom. The pathogenesis of the disease is due to genetic mutations affecting angiogenesis. For this reason, the anti-angiogenic therapy bevacizumab has gained popularity in the local treatment of epistaxis in patients with HHT. OBJECTIVE: A systematic review of the efficacy of bevacizumab in local treatment of epistaxis in patients with HHT based on epistaxis duration, frequency, severity and impact on quality of life...

Aging is associated with a vasoconstrictive, pro-coagulant, and pro-inflammatory profile of arteries and a decline in the bioavailability of the endothelium-derived molecule nitric oxide. Dietary nitrate elicits vasodilatory, anti-coagulant and anti-inflammatory effects in younger individuals, but little is known about whether these benefits are evident in older adults. We investigated the effects of 140 mL of nitrate-rich (HI-NI; containing 12.9 mmol nitrate) versus nitrate-depleted beetroot juice (LO-NI; containing ≤0...

BACKGROUND: Omalizumab has been shown to be effective in treating chronic spontaneous urticaria (CSU). The reduction of FcεRI receptor density on the surface of basophils and mast cells is thought to play a major role in its effectiveness. We conducted a double-blind, randomized, placebo-controlled trial to investigate the mode of action of omalizumab in patients with antihistamine-resistant CSU. METHODS: Thirty patients were randomized in a 2:1 ratio to receive either 300 mg omalizumab or placebo...

OBJECTIVE: Surgical treatment choice for coronary artery disease is coronary artery bypass grafting (CABG) surgery. Left internal mammary artery (LIMA) is frequently used as an arterial graft in CABG operations. Perioperative spasm of LIMA can result in increased morbidity and mortality. Pharmacological interventions are routinely used for prevention and treatment of LIMA spasm. In this study, we aimed to investigate the effects of carvedilol, an alpha- and beta-adrenergic receptor blocker, on responses to endogenous vasoconstrictors which play a role in graft spasm and the possible interaction between carvedilol and diltiazem/papaverine which are vasodilators commonly used in CABG surgery...

Rotigotine-a non-ergot dopamine agonist-has two advantages; it can stimulate all dopamine receptors (D1-D5) like innate dopamine, and its transdermal administration provides continuous dopaminergic stimulation. The age of the patient impacts the effect and adverse events of anti-parkinsonian treatment. We conducted a post hoc analysis on three randomized, double-blind, placebo-controlled trials performed in Japan to clarify the difference of anti-parkinsonian treatment in elderly and non-elderly patients. Data from two combination therapy trials (with levodopa) in advanced stage Parkinson's disease patients and one monotherapy trial in early stage patients were pooled and grouped by age (non-elderly aged < 70, elderly aged 70 +)...

Introduction: Gradual population aging is creating a new set of needs in the general population. Memory capacity decreases with age, and memory deficits are considered an early symptom of Alzheimer's Disease (AD), one of the most prevalent cognitive disorders in older people. Numerous studies have shown that grape polyphenolic compounds (GPs) are able to attenuate cognitive impairment and reduce brain lesions in experimental AD animal models. These GP effects are associated with improvement in brain antioxidant status and prevention of free radical-induced neuronal damage...
