Le fragment grec de l'homélie II d'Origène sur la Genèse. Critique du texte

This important excerpt on Noah's ark, taken from Origene's second Homily, has been published several times, by Gombefis, Montfaucon, Delarue and Baehrens. The first World War prevented Baehrens, the last editor, from leading exhaustive inquiries on the manuscript tradition, mainly on the Eclogae manuscripts ; having used Procope's commentary preserved in Monac. 538, Baehrens had unfortunately given an artificial text, bringing alongside and, in some places, conflating two different sources : Procope, who in his turn had put together texts of various or uncertain origin, and the Eclogae. Paying attention to the multiple sources, the recent studies on the Eclogae and the ascription to Origene of some Didyme's works, the new edition presents simultaneously Procope's text, the text of the Eclogae (Mosq. 385), Rufinus' latin translation and a french translation from the greek.Le long passage en grec qui concerne la forme et les dimensions de l'arche de Noé dans l'homélie II d'Origène a besoin d'une édition nouvelle. Baehrens l'a édité dans le Corpus de Berlin avec les homélies en latin, mais la guerre de 1914 l'a empêché d'approfondir son enquête à travers les manuscrits, spécialement dans ceux des Chaînes. Il avait pourtant procuré un texte continu de plus de cent lignes, en utilisant abondamment le commentaire de Procope que lui donnait le Monac. 358. Mais voulant trop bien faire, il avait construit un texte artificiel, juxtaposant et, à. certains endroits, mélangeant deux sources différentes : Procope, qui reproduit et amalgame des textes d'origine incertaine, et les Chaînes. Il faut donc une édition qui tienne compte de la diversité des sources, des analyses récentes des Chaînes et des attributions abusives à Origène de textes didymiens. Après l'histoire des efforts de Combefis, de Montfaucon, de Delarue et de Baehrens pour éditer les fragments, on donne ici l'édition nouvelle, qui présente en parallèle, sur quatre colonnes, texte de Procope, texte des Chaînes (Mosq. 385), traduction ( !) latine de Rufin et traduction française du texte grec.Doutreleau Louis.

Obstructive Sleep Apnea Syndrome, Objectively Measured Physical Activity and Exercise Training Interventions: A Systematic Review and Meta-Analysis

A systematic review of English and French articles using Pubmed/Medline and Embase included studies assessing objective physical activity levels of obstructive sleep apnea (OSA) patients and exploring the effects of exercise training on OSA severity, body mass index (BMI), sleepiness, and cardiorespiratory fitness [peak oxygen consumption (VO2peak)]. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. For objective physical activity levels, eight studies were included. The mean number of steps per day across studies was 5,388 (95% CI: 3,831–6,945; p < 0.001), which was by far lower than the recommended threshold of 10,000 steps per day. For exercise training, six randomized trials were included. There was a significant decrease in apnea–hypopnea-index following exercise training (mean decrease of 8.9 events/h; 95% CI: −13.4 to −4.3; p < 0.01), which was accompanied by a reduction in subjective sleepiness, an increase in VO2peak and no change in BMI. OSA patients present low levels of physical activity and exercise training is associated with improved outcomes. Future interventions (including exercise training) focusing on increasing physical activity levels may have important clinical impacts on both OSA severity and the burden of associated co-morbidities. Objective measurement of physical activity in routine OSA management and well-designed clinical trials are recommended.Registration # CRD42017057319 (Prospero)

Cardiovascular and metabolic responses to passive hypoxic conditioning in overweight and mildly obese individuals

International audienceAlthough severe intermittent hypoxia (IH) is well known to induce deleterious cardiometabolic consequences, moderate IH may induce positive effects in obese individuals. The present study aimed to evaluate the effect of two hypoxic conditioning programs on cardiovascular and metabolic health status of overweight or obese individuals. In this randomized single-blind controlled study, 35 subjects (54 ± 9.3 yr, 31.7 ± 3.5 kg/m 2 ) were randomized into three 8-wk interventions (three 1-h sessions per week): sustained hypoxia (SH), arterial oxygen saturation ([Formula: see text]) = 75%; IH, 5 min [Formula: see text] = 75% – 3 min normoxia; normoxia. Ventilation, heart rate, blood pressure, and tissue oxygenation were measured during the first and last hypoxic conditioning sessions. Vascular function, blood glucose and insulin, lipid profile, nitric oxide metabolites, and oxidative stress were evaluated before and after the interventions. Both SH and IH increased ventilation in hypoxia (+1.8 ± 2.1 and +2.3 ± 3.6 L/min, respectively; P 0.05). IH only reduced heart rate variability (e.g., root-mean-square difference of successive normal R-R intervals in normoxia −21 ± 35%; P < 0.05). Both SH and IH induced no significant change in body mass index, vascular function, blood glucose, insulin and lipid profile, nitric oxide metabolites, or oxidative stress, except for an increase in superoxide dismutase activity following SH. This study indicates that passive hypoxic conditioning in obese individuals induces some positive cardiovascular and respiratory improvements despite no change in anthropometric data and even a reduction in heart rate variability during IH exposure

Hypoxic high-intensity interval training in individuals with overweight and obesity

International audienceIntroduction. Combining moderate intensity exercise training with hypoxic exposure may induce larger improvement in cardiometabolic risk factors and health status compared to normoxic exercise training in obesity. Considering the greater cardiometabolic effects of high intensity intermittent training (HIIT), we hypothesized that hypoxic high-volume HIIT (H-HIIT) would induce greater improvement in cardiorespiratory fitness and health status despite a lower absolute training workload than normoxic HIIT (N-HIIT) in overweight/obesity. Methods. Thirty-one subjects were randomized to an 8-week H-HIIT (10 male and 6 female; age: 51.0±8.3years; BMI: 31.5±4kg·m -2 ) or N-HIIT (13 male and 2 female; age: 52.0±7.5years; BMI: 32.4±4.8kg·m -2 ) program (3 sessions/week; cycling at 80% or 100% of maximal workload for H-HIIT and N-HIIT, respectively; target arterial oxygen saturation for H-HIIT 80%, FiO 2 ~0.12, i.e. ~4,200m a.s.l.). Before and after training, the following evaluations were performed: incremental maximal and submaximal cycling tests, pulse-wave velocity, endothelial function, fasting glucose, insulin, lipid profile, and body composition. Results. Maximal exercise (VO 2peak : H-HIIT +14.2±8.3% versus N-HIIT +12.1±8.8%) and submaximal (ventilatory thresholds) capacity and exercise metabolic responses (power output at the crossover point and at maximal fat oxidation rate) increased significantly in both groups, with no significant difference between groups and without other cardiometabolic changes. H-HIIT induced a greater peak ventilatory response (ANOVA group×time interaction F=7.4, p=0.016) compared to N-HIIT. Conclusion. In overweight/obesity, the combination of normobaric hypoxia and HIIT was not superior for improving cardiorespiratory fitness improvement compared with HIIT in normoxia, although HIIT in hypoxia was performed at a lower absolute training workload
