Time Trends in Hospital-Referred Stroke and Transient Ischemic Attack: Results of a 7-Year Nationwide Survey in France

2010

<i>Background:</i> Nationwide evaluations of the burden of stroke are scarce. We aimed to evaluate trends in stroke and transient ischemic attack (TIA) hospitalization, in-hospital case fatality rates (CFRs) and mortality rates in France during 2000–2006. <i>Methods:</i> Hospitalizations for stroke and TIA were determined from National Hospital Discharge Diagnosis Records that used the International Classification of Disease, 10th revision, codes I60, I61, I63, I64, G45, G46. CFRs and mortality rates were estimated from the national death certificates database. <i>Results:</i> The total number of stays for stroke increased between 2000 and 2006 (88,371 vs…

Effects of nitroglycerin or pentaerithrityl tetranitrate treatment on the gene expression in rat hearts: evidence for cardiotoxic and cardioprotectiv…

2009

Nitroglycerin (NTG) and pentaerithrityl tetranitrate (PETN) are organic nitrates used in the treatment of angina pectoris, myocardial infarction, and congestive heart failure. Recent data show marked differences in the effects of NTG and PETN on the generation of reactive oxygen species. These differences are attributed to different effects of NTG and PETN on the expression of antioxidative proteins like the heme oxygenase-I. To analyze the expressional effects of NTG and PETN in a more comprehensive manner we performed whole genome expression profiling experiments using cardiac total RNA from NTG- or PETN-treated rats and DNA microarrays containing oligonucleotides representing 27,044 rat…

The Effect of Indobufen on the Activities of Selected Rat Liver Phase I and Phase II Drug Metabolizing Enzymes, Peroxisomal β-oxidation and Hepatic G…

1994

Abstract Oral administration of indobufen to male rats for three days at daily doses of 5, 10 and 20 mg kg−1 resulted in no changes in liver total glutathione, cytosolic glutathione S-transferases or microsomal epoxide hydrolase. Reduced glutathione appeared slightly diminished to about 84% of control at the highest dose level. Microsomal cytochrome P450-dependent ethoxyresorufin O-de-ethylase and pentoxyresorufin de-alkylase activities were decreased to 64% (not significantly) and 67% of control at the lowest dose level. 6α- and 7α-Hydroxytestosterone activities were decreased to 67 and 68% of control at the highest dose level. Cyanide-insensitive peroxisomal fatty acid β-oxidation was inc…

Plasma Metabolomic Profiles of Glycemic Index, Glycemic Load, and Carbohydrate Quality Index in the PREDIMED Study

2020

Background The quality of carbohydrate consumed, assessed by the glycemic index (GI), glycemic load (GL), or carbohydrate quality index (CQI), affects the postprandial glycemic and insulinemic responses, which have been implicated in the etiology of several chronic diseases. However, it is unclear whether plasma metabolites involved in different biological pathways could provide functional insights into the role of carbohydrate quality indices in health. Objectives We aimed to identify plasma metabolomic profiles associated with dietary GI, GL, and CQI. Methods The present study is a cross-sectional analysis of 1833 participants with overweight/obesity (mean age = 67 y) from 2 case-cohort s…

A randomized multicentre trial to compare revascularization with optimal medical therapy for the treatment of chronic total coronary occlusions

2018

Aims: The clinical value of percutaneous coronary intervention (PCI) for chronic coronary total occlusions (CTOs) is not established by randomized trials. This study should compare the benefit of PCI vs. optimal medical therapy (OMT) on the health status in patients with at least one CTO.Method and results: Three hundred and ninety-six patients were enrolled in a prospective randomized, multicentre, open-label, and controlled clinical trial to compare the treatment by PCI with OMT with a 2:1 randomization ratio. The primary endpoint was the change in health status assessed by the Seattle angina questionnaire (SAQ) between baseline and 12 months follow-up. Fifty-two percent of patients have …

Influence of HMB Supplementation and Resistance Training on Cytokine Response to Resistance Exercise

2014

The purpose of this study was to determine the effects of a multinutritional supplement including amino acids, β-hydroxy-β-methylbutyrate (HMB), and carbohydrates on cytokine responses to resistance exercise and training.Seventeen healthy, college-aged men were randomly assigned to a Muscle Armor™ (MA; Abbott Nutrition, Columbus, OH) or placebo supplement group and 12 weeks of resistance training. An acute resistance exercise protocol was administered at 0, 6, and 12 weeks of training. Venous blood samples at pre-, immediately post-, and 30-minutes postexercise were analyzed via bead multiplex immunoassay for 17 cytokines.After 12 weeks of training, the MA group exhibited decreased interfer…

Impact of Accessory Renal Artery Coverage on Renal Function during Endovascular Aortic Aneurysm Repair.

2021

Background Long-term outcomes of accessory renal artery (ARA) coverage after endovascular aneurysm repair (EVAR) are unknown. We analyzed the impact of ARA coverage on renal function long-term. Methods This retrospective, monocentric study included patients treated by EVAR between 2008 and 2016. Patients with at least one ARA covered with EVAR (ARA group) were compared with patients with no covered ARA (control group). Renal function was determined by estimating the glomerular filtration rate (eGFR) and graded according to chronic kidney disease (CKD) classification stages. Results A total of 184 patients were included (ARA group, n = 25; control group, n = 159). Renal risk factors were sim…

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 …

Early Sacubitril/Valsartan-driven Benefit on Exercise Capacity in Heart Failure With Reduced Ejection Fraction: A Pilot Study

2017

Action of metyrapone on the redox state of free nicotinamide-adenine dinucleotide and on oxygen consumption of perfused rat livers and isolated mitoc…

1971

Metyrapone [2-methyl-1,2-bis-(3-pyridyl)-1-propanone] in a concentration of 5 mM increased the lactate/pyruvate ratio and theΒ-hydroxybutyrate/ acetoacetate ratio in the perfusion fluid of the isolated rat liver by a factor of 6 indicating a considerable shift in the ratio of free [NAD]/[NADH] in both the cytoplasmic and the mitochondrial compartment. Oxygen uptake of the isolated liver was decreased to about one half. The onset of the inhibitory effect on the respiration of the isolated organ was immediate. The inhibition lasted for at least 1 h.
