Methods: This is a multicenter genetic association study. Sixty-eight patients presenting pigment epithelial detachments resistant to ranibizumab (issued from ARI2 study, register number NCT02157077 on clinicaltrials.

Compared characteristics of current vs. past smokers at the time of diagnosis of a first-time lung or head and neck cancer: a cross-sectional study.

Background: Active smoking at the time of diagnosis of a first head & neck (H&N) or lung cancer is associated with a worse cancer outcome and increased mortality. However, the compared characteristics of active vs. former smokers at cancer diagnosis are poorly known.

Diversity and distribution of alpha satellite DNA in the genome of an Old World monkey: Cercopithecus solatus.

Background: Alpha satellite is the major repeated DNA element of primate centromeres. Evolution of these tandemly repeated sequences has led to the existence of numerous families of monomers exhibiting specific organizational patterns. The limited amount of information available in non-human primates is a restriction to the understanding of the evolutionary dynamics of alpha satellite DNA.

Karyotype diversity suggests that Laonastes aenigmamus (Laotian rock rat) (Rodentia, Diatomyidae) is a multi-specific genus.

Laonastes aenigmamus (Khanyou) is a recently described rodent species living in geographically separated limestone formations of the Khammuan Province in Lao PDR. Chromosomes of 21 specimens of L. aenigmamus were studied using chromosome banding as well as fluorescent in situ hybridization (FISH) techniques using human painting, telomere repeats, and 28S rDNA probes.

National Esophageal Atresia Register.

National Esophageal Atresia was created in 2008 by the National Reference Center for Esophageal Congenital Abnormalities created in 2006. Primary goal was estimation of live birth prevalence in France. A national network of surgeons and pediatricians was initiated and entire teams dealing with esophageal atresia accepted to participate in an exhaustive national register.

CFH Y402H and ARMS2 A69S Polymorphisms and Oral Supplementation with Docosahexaenoic Acid in Neovascular Age-Related Macular Degeneration Patients: The NAT2 Study.

Purpose: Genetic susceptibility could be modified by environmental factors and may also influence differential responses to treatments for age-related macular degeneration (AMD). We investigated whether genotype could influence response to docosahexaenoic acid (DHA)-supplementation in the occurrence of choroidal new vessels (CNV).

Methods: The Nutritional AMD Treatment 2 (NAT2) study was a randomized, placebo-controlled, double-blind, parallel, comparative study, including 250 patients aged 55 to 85 years with early lesions of age-related maculopathy, visual acuity better than 0.

Use of emergency departments by known epileptic patients: An underestimated problem?

Background And Purpose: Seizure is a frequent reason of admission in emergency department (ED) but little is known about the proportion and the characteristics of known epileptic patients (KEPs) who used emergency services.

Methods: Over a 12-month period, we prospectively recruited adults admitted for seizure to a tertiary hospital ED. For KEPs, clinical epilepsy features and characteristics of the admission were collected.

Improvement of the initial management of sarcomas after the dissemination of evidence-based guidelines depends on the primary sarcoma location: a population-based study.

Background: Improvement of the initial management of sarcomas after the dissemination of evidence-based guidelines depends on the primary sarcoma location: a population-based study. To improve the initial management of adult sarcomas, a regional expert team in Northern France performed two actions: dissemination of evidence-based guidelines (EBG) for the management of soft tissue/visceral sarcoma and yearly educational symposia. The aim of this study was to measure the impact of the dissemination of EBG on the key-indicators of adult sarcoma management.

Telomere regulation during ageing and tumorigenesis of the grey mouse lemur.

Telomere erosion leading to replicative senescence has been well documented in human and anthropoid primates, and provides a clue against tumorigenesis. In contrast, other mammals, such as laboratory mice, with short lifespan and low body weight mass have different telomere biology without replicative senescence. We analyzed telomere biology in the grey mouse lemur, a small prosimian model with a relative long lifespan currently used in ageing research.

Treatment of sleep apnoea syndrome decreases cognitive decline in patients with Alzheimer's disease.

Background: It is essential to detect and then treat factors that aggravate Alzheimer's disease (AD). Here, we sought to determine whether or not continuous positive airway pressure (CPAP) therapy for sleep apnoea syndrome (SAS) slows the rate of cognitive decline in mild-to-moderate AD patients.

Methods: Between January 2003 and June 2011, we included consecutive, mild-to-moderate AD patients (a Mini Mental State Examination (MMSE) score at inclusion ≥15) with severe SAS as determined by video-polysomnography (an apnoea-hypopnoea index ≥30).

Genetic association study of mitochondrial polymorphisms in neovascular age-related macular degeneration.

Purpose: Age-related macular degeneration (AMD) is a multifactorial disease involving genetic and environmental factors. Most of the genetic factors identified so far involve the nuclear genome. Recently, two studies in North America and Australia reported an association between advanced AMD and the mitochondrial T2 haplogroup.

Association between caffeine intake and age at onset in Huntington's disease.

Habitual consumption of caffeine, a non-selective adenosine receptor (AR) antagonist, has been suggested to be beneficial in Parkinson's and Alzheimer's diseases. Experimental evidence support that ARs play a role in Huntington's disease (HD) raising the hypothesis that caffeine may be a life-style modifier in HD. To determine a possible relationship between caffeine consumption and age at onset (AAO) in HD, we retrospectively assessed caffeine consumption in 80 HD patients using a dietary survey and determined relationship with AAO.

Influence of chronic ethanol consumption on the neurological severity in patients with acute cerebral ischemia.

Background And Purpose: We tested the hypothesis that excessive chronic ethanol consumption is associated with more severe ischemic strokes.

Methods: We recruited patients with supratentorial cerebral ischemia within 48 hours of symptom onset. We defined heavy drinkers by a weekly consumption of ethanol of ≥300 g and severe strokes by a National Institutes of Health Stroke Scale score≥6.

Genetic and environmental factors associated with reticular pseudodrusen in age-related macular degeneration.

Purpose: To analyze the genetic and environmental factors associated with reticular pseudodrusen (RPD) in age-related macular degeneration (AMD).

Methods: In a large population, AMD patients (n = 519) with and without RPD were assessed with a standardized examination including infrared images and spectral domain optical coherence tomography scans. Three groups were defined: Group 1: AMD patients with RPD (n = 105); Group 2: AMD patients without RPD (n = 414); and Group 3: controls with no AMD and no RPD (n = 430).

Single nucleotide polymorphism in the cholesterol-24S-hydroxylase (CYP46A1) gene and its association with CFH and LOC387715 gene polymorphisms in age-related macular degeneration.

Purpose: We investigated the association of single nucleotide polymorphism (SNP) in the cholesterol-24S-hydroxylase (CYP46A1) gene, according to CFH and LOC387715 SNPs, with age-related macular degeneration (AMD).

Methods: We enrolled 1388 AMD patients with neovascular AMD or geographic atrophy and 487 unrelated control subjects. SNPs were genotyped in the CYP46A1 (rs754203), LOC387715 (rs10490924), and CFH (rs1061170) genes.

Plasma amyloid-β levels and prognosis in incident dementia cases of the 3-City Study.

Studies of plasma amyloid-β (Aβ) levels as potential biomarkers for incident Alzheimer's disease (AD) have yielded contradictory results. We explored the associations between plasma Aβ(40), Aβ(42), and truncated Aβ levels, and prognosis of dementia in participants of the prospective 3-City Study. 120 aged individuals diagnosed with 2-year incident dementia were followed up for seven years.

Can the treatment of vascular risk factors slow cognitive decline in Alzheimer's disease patients?

Dementia is a widespread disorder with major medical, economic and societal costs. Controlling vascular conditions could be one way of delaying the progression of Alzheimer's disease (AD). In fact, vascular risk factors are implicated in AD occurrence.

Modifying effect of arterial hypertension on amyotrophic lateral sclerosis.

Given the high oxygen consumption of motor neurons, we sought to assess the frequency and prognostic value of arterial hypertension (affecting brain's oxygen supply) in amyotrophic lateral sclerosis (ALS). We consecutively and prospectively included all ALS patients with regular medical follow-up and documented blood pressure measurements and monitored them until death. Vascular factors diagnosed prior to the onset of motor signs in ALS patients were compared with those in a stratified, age- and gender-matched case-control population.

Aldosterone, mortality, and acute ischaemic events in coronary artery disease patients outside the setting of acute myocardial infarction or heart failure.

Background: Recent studies have demonstrated that aldosterone levels measured in patients with heart failure or acute myocardial infarction (MI) are associated with long-term mortality, but the association with aldosterone levels in patients with coronary artery disease (CAD) outside these specific settings remains unknown. In addition, no clear mechanism has been elucidated to explain these observations. The present study was designed to evaluate the relationship between the level of aldosterone and the risk of death and acute ischaemic events in CAD patients with a preserved left ventricular (LV) function and no acute MI.

No association between the T280M polymorphism of the CX3CR1 gene and exudative AMD.

Major genetic factors for age-related macular degeneration (AMD) have recently been identified as susceptibility risk factors. The CX3CR1 gene has been shown to be associated with AMD in some studies. Our purpose was to analyze the role of the T280M polymorphism of the CX3CR1 gene in a large French population, in a case-control study.

Association of plasma Aß peptides with blood pressure in the elderly.

Background: Aß peptides are often considered as catabolic by-products of the amyloid ß protein precursor (APP), with unknown physiological functions. However, several biological properties have been tentatively attributed to these peptides, including a role in vasomotion. We assess whether plasma Aß peptide levels might be associated with systolic and diastolic blood pressure values (SBP and DBP, respectively).
