White blood count, D-dimers, and ferritin levels as predictive factors of pulmonary embolism suspected upon admission in noncritically ill COVID-19 patients: The French multicenter CLOTVID retrospective study.

Background: A high prevalence of pulmonary embolism (PE) has been described during COVID-19. Our aim was to identify predictive factors of PE in non-ICU hospitalized COVID-19 patients.

Methods: Data and outcomes were collected upon admission during a French multicenter retrospective study, including patients hospitalized for COVID-19, with a CT pulmonary angiography (CTPA) performed in the emergency department for suspected PE.

D-Dimer Level and Neutrophils Count as Predictive and Prognostic Factors of Pulmonary Embolism in Severe Non-ICU COVID-19 Patients.

The incidence of pulmonary embolism (PE) is high during severe Coronavirus Disease 2019 (COVID-19). We aimed to identify predictive and prognostic factors of PE in non-ICU hospitalized COVID-19 patients. In the retrospective multicenter observational CLOTVID cohort, we enrolled patients with confirmed RT-PCR COVID-19 who were hospitalized in a medicine ward and also underwent a CT pulmonary angiography for a PE suspicion.

Biophysical interactions control the size and abundance of large phytoplankton chains at the Ushant tidal front.

Phytoplankton blooms are usually dominated by chain-forming diatom species that can alter food pathways from primary producers to predators by reducing the interactions between intermediate trophic levels. The food-web modifications are determined by the length of the chains; however, the estimation is biased because traditional sampling strategies damage the chains and, therefore, change the phytoplankton size structure. Sedimentological studies around oceanic fronts have shown high concentrations of giant diatom mats (>1 cm in length), suggesting that the size of diatom chains is underestimated in the pelagic realm.

[Functional capacity after cardiac transplantation].

Cardiac transplantation has transformed the prognosis of NYHA Class IV severe cardiac failure. However, despite a "new heart", the exercise tolerance of transplanted patients remains poor for a long time. Cardiac denervation which decreases the chronotropic reserve, diastolic left ventricular dysfunction and intrinsic muscular abnormalities related to lack of training and to treatment are the underlying causes.

[Study of representative periods of day-time and night-time levels of blood pressure].

Unlabelled: The aim of this study is to assess whether it is possible to shorten ambulatory blood pressure (ABP) monitoring while getting measurements that precisely reflect 24 hours and daytime blood pressure (BP).

Methods: three hundred and thirty six young male subjects aged: 21 +/- 2 y, height: 178 +/- 7 cm, weight, 75 +/- 12 kg, with normal or "borderline" BP (casual BP: 138 +/- 13/79 +/- 8 mmHg) participated in the study. BP was recorded in each, every 15 minutes on 24 hours with a Spacelabs 5200 device.
