    International audienceHigh cadence observations of solar activity (active regions, flares, filaments) in the Hα line were performed at Meudon and Haute Provence Observatories from 1956 to 2004. More than 7 million images were recorded, mainly on 35 mm films. After a review of the scientific interest of solar surveys at high temporal resolution and the historical background, we describe the new instrument which will operate automatically in 2020 at the Calern station of the CĂŽte d’Azur observatory (1270 m). It will replace the former heliographs with improved cadence, seeing and time coverage. We summarize the capabilities of the optical design and present new scientific perspectives in terms of flare onset and Moreton wave detection

    "ReaNet", the Internet utilization among surrogates of critically ill patients with sepsis

    International audienceContext Health-related Internet utilization is common but its use by proxies of critically ill patients is unknown. Our objective was to describe the prevalence and the Internet utilization characteristics among surrogates of critically ill septic patients. We conducted a prospective observational study in French ICUs. Three survey instruments were used to describe ICU organization regarding information delivery, patients and surrogates characteristics Results 169 surrogates of 146 septic patients hospitalized in 19 ICUs were included. One sixth of ICUs (n = 3, 16%) had their own website. Majority of patients were males (n = 100, 68%), aged 64 1 years old, with a SAPS2 score at 53 17 and required vasopressors (n = 117, 83%), mechanical ventilation (n =116, 82%). More than one quarter required renal replacement therapy (n = 36, 26%). Majority of surrogates were female, in their fifties. Only one in five knew the word sepsis (n = 27, 16%). Majority of proxies internet users (n = 77; 55%) search on the internet about sepsis. The main motivation was curiosity. Majority of surrogates found the information online reliable, suitable for request and concordant. Prior use of health-related Internet (OR = 20.7 [4.30-100.1]), the presence of a nursing staff during family -physician meetings (OR = 3.33 [1.17-9.53]), a younger patient age (OR = 1.32 [1.01-1.72]) and renal replacement therapy requirement (OR = 2.58 [1.06-6.26]) were associated with health-related Internet use. Neither satisfaction with medical care or information provision, neither presence of anxiety-depression symptoms, were associated with health related Internet use. Majority of surrogates (N = 76 (52%)) would have like receiving a list of selected websites on sepsis. Conclusions Majority of proxies of critically ill patients with sepsis use Internet to learn more about sepsis. Internet utilization is independent of satisfaction with global ICU care, perceived quality of information delivery by doctors or the existence of anxiety-depression symptoms during ICU stay. The delivery of a list of recommended web sites on sepsis would have been appreciated
