Anomalous origin of all three coronary arteries from right sinus of Valsalva
2016
AbstractCongenital anomalies of the coronary arteries, although uncommon, have the potential to cause serious myocardial damage, ischemic cardiomyopathy, and sudden cardiac death. We report a rare case of origin of all three coronaries from the right sinus of Valsalva.
The carotid pulse check revisited: What if there is no pulse?
2000
This study was undertaken to evaluate the diagnostic accuracy and time required by first responders to assess the carotid pulse in potentially pulseless patients. We conducted a prospective, randomized study of first responders (n = 206; four different training levels) and were blinded as to the patients' conditions in the cardiac operating rooms of a university hospital. Sixteen patients underwent coronary artery bypass surgery on nonpulsatile cardiopulmonary bypasses. Carotid pulse check was performed either during pulsatile (spontaneous) or during nonpulsatile (extracorporeal) circulation. Patients' hemodynamic status at the time of assessment, diagnostic accuracy of the first responders…
Arterial stiffness, endothelial and cognitive function in subjects with type 2 diabetes in accordance with absence or presence of diabetic foot syndr…
2017
BACKGROUND: Endothelial dysfunction is an early marker of cardiovascular disease so endothelial and arterial stiffness indexes are good indicators of vascular health. We aimed to assess whether the presence of diabetic foot is associated with arterial stiffness and endothelial function impairment. METHODS: We studied 50 subjects with type 2 diabetes mellitus and diabetic foot syndrome (DFS) compared to 50 diabetic subjects without diabetic foot, and 53 patients without diabetes mellitus, by means of the mini mental state examination (MMSE) administered to evaluate cognitive performance. Carotid-femoral pulse wave velocity (PWV) and augmentation index (Aix) were also evaluated by Applanation…
Early-onset tolerance in rat global cerebral ischemia induced by a mitochondrial inhibitor
2000
It was studied whether a subtoxic dose of the mitochondrial neurotoxin, 3-nitropropionic acid (3-NPA), can initiate early-onset tolerance induction for subsequent ischemic injury. Wistar rats were pretreated for 3 h by intraperitoneal 3-NPA (20 mg/kg body weight; n=13) or solvent (n=12). Fifteen minutes global cerebral ischemia was induced by bilateral carotid artery occlusion and hypobaric hypotension. rCBF and tissue hemoglobin oxygen saturation were measured by laser Doppler scanning and a microspectrophotometric method. Ischemic insult and brain temperature were identical in both groups. Body weight and neurological scores recovered in the pretreated group but further deteriorated in th…
A randomized, double-blind comparison of antiepileptic drug treatment in the elderly with new-onset focal epilepsy.
2015
Objective: To compare the effectiveness of controlled-released carbamazepine (CR-CBZ) to levetiracetam (LEV) and to lamotrigine (LTG) in elderly patients with newlydiagnosedfocalepilepsy.Methods: Randomized, double-blind, parallel-group trial conducted between January2007andAugust2011,in47ambulatoryorhospitalsitesinGermany,Austria,orSwit-zerland. Eligible participants were aged ≥60, had new-onset epilepsy, had no acute ill-nessasthecauseoftheirseizures,andhadnocontraindicationtothedrugsinthetrial.Patients were randomized 1:1:1 to CR-CBZ, LTG, or LEV. Doses were up-titrated for6 weeks and could be maintained or adjusted depending on seizure relapse or tolera-bility over an additional period …
Sacubitril/valsartan and short-term changes in the 6-minute walk test: A pilot study
2018
Background: Impaired exercise capacity is the most disabling symptom in patients with heart failure with reduced ejection fraction (HFrEF). Despite sacubitril/valsartan showing reduced long-term morbidity and mortality over enalapril in HFrEF, its effects on short-term functional capacity remain uncertain. We sought to evaluate the effects of sacubilril/valsartan on a 30-day six-minute walk test in eligible patients with HFrEF. Methods and results: From November 1, 2016 to February 1, 2017, a total of 58 stable symptomatic patients with HFrEF were eligible for sacubitril/valsartan and underwent 6-MWT before and 30 days after initiation of sacubitril/valsartan therapy. A mixed-effects model …
Effects of clozapine metabolites and chronic clozapine treatment on rat brain GABAA receptors
1996
Abstract Similarly to clozapine, a clozapine metabolite, N -desmethylclozapine, but not clozapine N -oxide, antagonized brain γ-aminobutyric acid type A (GABA A ) receptors at high micromolar concentrations. However, daily subcutaneous injections of clozapine (10 and 25 mg/kg) and haloperidol (0.5 mg/kg) for 14 days failed to alter the modulation by GABA of rat cerebrocortical and cerebellar benzodiazepine ([ 3 H]flunitrazepam) or convulsant ( t -[ 35 S]bicyclophosphorothionate) binding sites of the GABA A receptor. The results thus suggest that the GABA A receptor antagonism exerted by chronic in vivo clozapine treatment is weak as compared to this treatment's actions on certain monoamine …
Early Sacubitril/Valsartan-driven Benefit on Exercise Capacity in Heart Failure With Reduced Ejection Fraction: A Pilot Study
2017
Effect of a Strategy of Comprehensive Vasodilation vs Usual Care on Mortality and Heart Failure Rehospitalization Among Patients With Acute Heart Fai…
2019
Importance Short-term infusions of single vasodilators, usually given in a fixed dose, have not improved outcomes in patients with acute heart failure (AHF). Objective To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation using individualized up-titrated doses of established vasodilators in patients with AHF. Design, Setting, and Participants Randomized, open-label blinded-end-point trial enrolling 788 patients hospitalized for AHF with dyspnea, increased plasma concentrations of natriuretic peptides, systolic blood pressure of at least 100 mm Hg, and plan for treatment in a general ward in 10 tertiary and secondary hospitals in Switzerland, Bulgari…
Health-related quality of life in patients with poststroke epilepsy.
2017
Abstract Background Lesional epilepsy is an important long-term sequela of stroke. Data on health-related quality of life (HrQoL) in patients with poststroke epilepsy are limited. We investigated HrQoL in patients with epilepsy after ischemic stroke and identified independent HrQoL-determinants. Methods and patients All patients with acute ischemic stroke, who were permanent residents in the district Marburg-Biedenkopf (Hessia, Germany, reference population 240,000 inhabitants) were recruited within 12 months in the population-based Marburg Stroke Register (MARSTREG). Follow-up visits were performed after 6, 12, and 24 months, and patients who developed poststroke epilepsy were identified. …
