Enoxaparin versus Placebo to Prevent Symptomatic Venous Thromboembolism in Hospitalized Older Adult Medical Patients.

BACKGROUND: Admission to the hospital is a major risk factor for the development of venous thromboembolism (VTE). Whether thromboprophylaxis with low-molecular-weight heparin prevents symptomatic VTE in medically ill, hospitalized older adults remains debated. METHODS: In a prospective, randomized, placebo-controlled, double-blind, multicenter trial, older adults (>70 years of age) hospitalized for acute medical conditions were randomly assigned to receive 40 mg a day of low-molecular-weight heparin (enoxaparin) or placebo for 6 to 14 days.

Impact of an enhanced focused cardiac ultrasound on treatment changes in a population of internal medicine patients.

Background: Hospitalized patients with acute shortness of breath (SOB) could benefit from an enhanced focused cardiac ultrasound (eFoCUS) with Doppler measurements to reassess treatment and diagnosis.

Methods: This was a retrospective observational study performed in a medical ward. Included patients were those hospitalized for acute SOB.

Impact of Different Training Methods on Daily Use of Point-of-Care Ultrasound: Survey on 515 Physicians.

Point-of-care ultrasound (POCUS) curriculum varies among countries. However, the length of training required for physicians is still under debate. We investigated the impact of different training methods: short hands-on courses (STS), long academic training sessions (LTS), or both (mixed training [MTS]), for POCUS daily use and self-reported confidence overall and specific to specific clinical situations.

Electrocardiographic abnormalities in COVID-19 patients visiting the emergency department: a multicenter retrospective study.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be associated with myocardial injury. Identification of at-risk patients and mechanisms underlying cardiac involvement in COVID-19 remains unclear. During hospitalization for COVID-19, high troponin level has been found to be an independent variable associated with in-hospital mortality and a greater risk of complications.

Contribution of lung ultrasound in diagnosis of community-acquired pneumonia in the emergency department: a prospective multicentre study.

Unlabelled: Lung ultrasound (LUS) can help clinicians make a timely diagnosis of community-acquired pneumonia (CAP).

Objectives: To assess if LUS can improve diagnosis and antibiotic initiation in emergency department (ED) patients with suspected CAP.

Design: A prospective observational study.

Hyponatremia is associated with poor outcome in COVID-19.

Aim: Our objective was to describe the impact of hyponatremia on the outcomes of COVID-19 patients [outcomes selected: intensive care unit (ICU) admission, mechanical ventilation or death].

Methods: Two groups of COVID-19 patients were retrospectively screened on the basis of plasma sodium level at admission: hyponatremic (sodium < 135 mM, n = 92) or normonatremic (sodium ≥ 135 mM, n = 198) patients. Pearson's chi- (qualitative variables) and Student's T tests (quantitative variables) were used to compare the two groups.

Electrolyte imbalance in COVID-19 patients admitted to the Emergency Department: a case-control study.

In patients visiting the emergency department (ED), a potential association between electrolytes disturbance and coronavirus disease 2019 (COVID-19) has not been well studied. We aim to describe electrolyte disturbance and explore risk factors for COVID-19 infection in patients visiting the ED. We carried out a case-control study in three hospitals in France, including adult ED inpatients (≥ 18 years old).

Effect of chest ultrasound on diagnostic workup in elderly patients with acute respiratory failure in the emergency department: a prospective study.

Methods: We carried out a prospective study performed in our ED, included patients older than 75 years presenting with acute respiratory failure. Noninclusion criteria were documented palliative care or the need for immediate intensive care. After informed consent approval and routine diagnostic procedure (clinical, radiological and laboratory tests), the ED physician established the first diagnosis.

Challenges in the serological evaluation of dogs clinically suspect for canine leishmaniasis.

Canine leishmaniasis is a major veterinary issue and also a public health challenge due to its zoonotic potential. In this context, serological evaluation is essential for Canine leishmaniasis management. Several serological alternatives, such as rapid diagnostic tests, enzyme-linked immunosorbent assay (ELISA) and immunofluorescence antibody test (IFAT), are well established.

Maximum Value of End-Tidal Carbon Dioxide Concentrations during Resuscitation as an Indicator of Return of Spontaneous Circulation in out-of-Hospital Cardiac Arrest.

The end-tidal carbon dioxide (ETCO) concentration during resuscitation (CPR) of an out-of-hospital cardiac arrest (OHCA) has an increasingly well-known prognostic value. Nevertheless, few studies have investigated its maximum value in different etiologies. It was a retrospective, observational, multicentre study from the French OHCA Registry.

Thrombolysis During Resuscitation for Out-of-Hospital Cardiac Arrest Caused by Pulmonary Embolism Increases 30-Day Survival: Findings From the French National Cardiac Arrest Registry.

Background: Pulmonary embolism (PE) represents 2% to 5% of all causes of out-of-hospital cardiac arrest (OHCA) and is associated with extremely unfavorable prognosis. In PE-related OHCA, inconsistent data showed that thrombolysis during cardiopulmonary resuscitation may favor survival.

Methods: This was a retrospective, observational, multicenter study from July 2011 to March 2018.

Impact of pre-hospital vital parameters on the neurological outcome of out-of-hospital cardiac arrest: Results from the French National Cardiac Arrest Registry.

Introduction: The targets for vital parameters following return of spontaneous circulation (ROSC) from an out-of-hospital cardiac arrest (OHCA) are based on studies carried out predominantly in intensive care units. Therefore, we studied the pre-hospital phase.

Method: We included all adult OHCA from the French OHCA Registry.

Multifunctional nanostructured Co-doped ZnO: Co spatial distribution and correlated magnetic properties.

In this report we present a systematic structural and magnetic analysis of Co-doped ZnO nanoparticles prepared via a microwave-assisted hydrothermal route. The structural data confirm the incorporation of Co ions into the wurtzite ZnO lattice and a Co concentration mainly near/at the surface of the nanoparticles. This Co spatial distribution is set to passivate the surface of the ZnO nanoparticles, inhibiting the nanoparticle growth and suppressing the observation of a ferromagnetic phase.

Unique PFK regulatory property from some mosquito vectors of disease, and from Drosophila melanogaster.

Background: Arthropod-borne diseases are some of the most rapidly spreading diseases. Reducing the vector population is currently the only effective way to reduce case numbers. Central metabolic pathways are potential targets to control vector populations, but have not been well explored to this aim.

Central auditory processing in patients with spinocerebellar ataxia.

Background: Autosomal dominant spinocerebellar ataxias (SCAs) are a group of rare and heterogeneous neurodegenerative diseases characterized by the presence of progressive cerebellar ataxia. Although the symptomatology of SCAs is well known, information regarding central auditory functioning in these patients is lacking. Therefore, we assessed the central auditory processing disorders (CAPD) in patients with different subtypes of SCA.
