Age–Period–Cohort Analysis of Stroke Incidence in Dijon From 1985 to 2005
2010
Background and Purpose— Variations in stroke incidence could be explained by changes in vascular and environmental factors that affect the risk of stroke and changes in risk factors that are present in early life. The aim of this study was to identify and measure the effects of 3 interrelated factors, age, calendar period of stroke onset, and birth year cohort, on the incidence rates of stroke from 1985 through 2005. Methods— Age–period–cohort models were used to analyze stroke incidence in Dijon from 1985 to 2005 from a population-based registry that collects data on all stroke patients whatever the type of management, in the public hospital, private hospitals, or at home, in the populati…
Influence of Preexisting Cognitive Impairment on Clinical Severity of Ischemic Stroke: The Dijon Stroke Registry.
2020
Background and Purpose— The ongoing ageing population is associated with an increasing number of patients with stroke who have preexisting cognitive impairment. This study aimed to evaluate clinical severity in patients with ischemic stroke according to prestroke cognitive status. Methods— Patients with ischemic stroke were prospectively identified among residents of Dijon, France using a population-based registry (2013–2017). Prestroke cognitive status (no impairment, mild cognitive impairment [MCI], or dementia) was recorded, and severity at stroke onset was measured using the National Institutes of Health Stroke Scale (NIHSS) score. Association between prestroke cognitive status and sev…
The hematopoietic factor G-CSF is a neuronal ligand that counteracts programmed cell death and drives neurogenesis.
2005
G-CSF is a potent hematopoietic factor that enhances survival and drives differentiation of myeloid lineage cells, resulting in the generation of neutrophilic granulocytes. Here, we show that G-CSF passes the intact blood-brain barrier and reduces infarct volume in 2 different rat models of acute stroke. G-CSF displays strong anti-apoptotic activity in mature neurons and activates multiple cell survival pathways. Both G-CSF and its receptor are widely expressed by neurons in the CNS, and their expression is induced by ischemia, which suggests an autocrine protective signaling mechanism. Surprisingly, the G-CSF receptor was also expressed by adult neural stem cells, and G-CSF induced neurona…
Different postischemic protein expression of the GABA_{A} receptor α2 subunit and the plasticity-associated protein MAP1B after treatment with BDNF v…
2009
Purpose Recent data indicate that both brain-derived neurotrophic factor (BDNF) and granulocyte-colony stimulating factor (G-CSF) exert substantial neuroregenerative effects and improve functional outcome after ischemic stroke. In the present study, we checked for potential differences in the postischemic modulation of various excitatory and inhibitory neurotransmitter receptors as well as various marker molecules for structural plasticity by BDNF versus G-CSF. Methods Adult male Wistar rats were subjected to photothrombotic ischemia and subsequently treated with NaCl, BDNF or G-CSF, respectively. After 6 weeks, postischemic protein expression of the NR1, GluR1 and alpha2 subunit of the NMD…
MRI patient selection for endovascular thrombectomy in acute ischemic stroke: correlation between pretreatment diffusion weighted imaging and outcome…
2018
Introduction: Eligibility for endovascular treatment (EVT) in patients with acute ischemic stroke (AIS) depends, amongst other factors, on CT- or MR-based scores. The aim of this study was to investigate the role of Alberta Stroke Program Early CT score based on diffusion weighted imaging (MR-ASPECT) in the assessment of brain damage pre-EVT, patient selection for EVT and outcome. Materials and methods: We included in this study patients with National Institute of Health stroke score (NIHSS) at admission ≥ 8, MR-ASPECT ≥ 5 and anterior AIS, who were treated with EVT in our hospital. All patients were clinically evaluated at admission, post-EVT, discharge and at 3-month follow-up. We used MR…
Prognosis, disease progression, and treatment of atrial fibrillation patients during 1 year: follow-up of the Euro Heart Survey on Atrial Fibrillation
2008
Aims: To gain insight in the prognosis and treatment of atrial fibrillation (AF) patients during 1-year follow-up in the Euro Heart Survey (EHS) on AF. Methods and results: The EHS enrolled 5333 AF patients in 2003-2004. One-year follow-up data were available for 80%. Of first detected AF patients, 46% did not have a recurrence during 1 year, paroxysmal AF largely remained paroxysmal AF (80%), and 30% of persistent AF progressed to permanent AF. Many treatment changes occurred since baseline. Oral anticoagulation was started in 19% and discontinued in 16% of all patients. Of patients initially on rhythm control 27% did not receive rhythm control during follow-up, whereas 15% of patients ini…
Home-based inspiratory muscle training for management of older patients with heart failure with preserved ejection fraction: does baseline inspirator…
2019
Background:Heart failure with preserved ejection fraction is a clinical syndrome characterised by reduced exercise capacity. Some evidence has shown that a simple and home-based programme of inspiratory muscle training offers promising results in terms of aerobic capacity improvement in patients with heart failure with preserved ejection fraction. This study aimed to investigate whether the baseline inspiratory muscle function predicts the changes in aerobic capacity (measured as peak oxygen uptake; peak VO2) after a 12-week home-based programme of inspiratory muscle training in patients with heart failure with preserved ejection fraction.Methods:A total of 45 stable symptomatic patients wi…
Resting heart rate and cardiovascular outcomes in diabetic and non-diabetic individuals at high cardiovascular risk analysis from the ONTARGET/TRANSC…
2018
Abstract Aims Resting heart rate (RHR) has been shown to be associated with cardiovascular outcomes in various conditions. It is unknown whether different levels of RHR and different associations with cardiovascular outcomes occur in patients with or without diabetes, because the impact of autonomic neuropathy on vascular vulnerability might be stronger in diabetes. Methods and results We examined 30 937 patients aged 55 years or older with a history of or at high risk for cardiovascular disease and after myocardial infarction, stroke, or with proven peripheral vascular disease from the ONTARGET and TRANSCEND trials investigating ramipril, telmisartan, and their combination followed for a m…

COPD significantly increases cerebral and cardiovascular events in hypertensives
2021
AbstractEssential hypertension and chronic obstructive pulmonary disease often coexist in the same patient. The aim of this study was to evaluate whether the addition of chronic obstructive pulmonary disease modifies the risk of cardiovascular events in hypertensives. We enrolled 1728 hypertensives. Study outcomes included fatal and non-fatal cardiovascular stroke and myocardial infarction, and cardiovascular death. During a mean follow-up of 57 months there were 205 major adverse cardiovascular events (2.47 per 100 pts/yr): cardiac (n117; 1.41 per 100 pts/yr) and cerebrovascular (n = 77; 0.93 per 100 pts/yr). In hypertensives with chronic obstructive pulmonary disease we observed a greater…
