Skin conductance measurement for the assessment of analgosedation adequacy in infants treated with mechanical ventilation: A multicenter pilot study
2020
Background Patients treated in neonatal/pediatric intensive care units (N/PICUs) are frequently exposed to pain. To assess its severity, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients. Objectives To evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs. Material and methods Thirty infants aged 6-208 days treated in 6 N/PICUs, mechanically ventilated and receiving analgosedation, were included for the stud…
Maternal and perinatal outcomes of pregnant women with SARS-CoV-2 infection
2021
WOS:000613461600006 PubMed ID: 32926494 Objectives To evaluate the maternal and perinatal outcomes of pregnancies affected by SARS-CoV-2 infection. Methods This was a multinational retrospective cohort study including women with a singleton pregnancy and laboratory-confirmed SARS-CoV-2 infection, conducted in 72 centers in 22 different countries in Europe, the USA, South America, Asia and Australia, between 1 February 2020 and 30 April 2020. Confirmed SARS-CoV-2 infection was defined as a positive result on real-time reverse-transcription polymerase chain reaction (RT-PCR) assay of nasopharyngeal swab specimens. The primary outcome was a composite measure of maternal mortality and morbidity…
P 042 - Gait complexity quantified using inertial measurement units in children with cerebral palsy
2018
Abstract Children with cerebral palsy (CP) have gait impairments, and their gait is affected by concurrent tasks. We used inertial measurement units (IMU) to quantify CP-related gait complexity alterations, and identify effects of dual tasks on gait variability from 12 children with CP and 23 typically developed (TD) controls. The data were collected for normal and dual-tasks (motor; carrying a tray, cognitive; word naming) during walking. Step duration and adjusted multiscale entropy (MSE) index were computed. In overall, children with CP had shorter step duration and greater gait complexity than TD. Gait complexity was higher in vertical direction during the cognitive than normal and moto…
Mr-Proadm Elevation Upon Icu Admission Predicts the Outcome of Septic Patients and is Correlated with Upcoming Fluid Overload.
2017
IF 3.113; International audience; Background: Among septic patients admitted to the intensive care unit (ICU), early recognition of those with the highest risk of death is of paramount importance. We evaluated the prognostic value of Procalcitonin (PCT), mid regional-proadrenomedullin (MR-proADM), copeptine and CT-proendothelin 1 (CT-ProET 1) concentrations. Methods: This was a prospective cohort study, which included 173 septic patient admitted to one ICU. Blood samples for biomarker measure-ments were obtained upon admission and on day 5. The predictive value of each biomarker regarding the risk of death at day 28 was assessed. The fluid balance was evaluated from admission to day 5. Resu…
Biological response of multicellular emt6 spheroids to exogenous lactate
1991
The influence of elevated lactate concentrations, as found in tumor microregions, on cellular growth, viability, and metabolic state was studied employing the multicellular spheroid model. Spheroids of EMT6/Ro cells were cultured at 37 degrees C in 5% or 20% (v/v) oxygen, using stirred media with various concentrations of exogenous lactate ranging from 0.0 mM (standard conditions) to 20.0 mM. Elevated concentrations of exogenous lactate led to a considerable decrease of the maximum spheroid diameter at growth saturation, e.g., for 20% O2 from around 1700 microns to 700 microns in 0.0 and 20.0 mM lactate respectively. Histological investigations showed that the thickness of the viable cell r…
The new iodoacetamidobenzofuran derivative TR120 decreases STAT5 expression and induces antitumor effects in imatinib-sensitive and imatinib-resistan…
2013
The identification of novel compounds modulating the expression/activity of molecular targets downstream to BCR-ABL could be a new approach in the treatment of chronic myeloid leukemias (CMLs) resistant to imatinib or other BCR-ABL-targeted molecules. Recently, we synthesized a new class of substituted 2-(3,4,5-trimethoxybenzoyl)-2-N,N-dimethylamino-benzo[b]furans, and among these 3-iodoacetylamino-6-methoxybenzofuran-2-yl(3,5-trimethoxyphenyl)methanone (TR120) showed marked cytotoxic activity in BCR-ABL-expressing cells. Interestingly, TR120 was more potent than imatinib in cell growth inhibition and apoptosis induction in both BCR-ABL-expressing K562 and KCL22 cells. Moreover, it showed a…
Chemokine stromal cell-derived factor-1alpha modulates VLA-4 integrin-dependent adhesion to fibronectin and VCAM-1 on bone marrow hematopoietic proge…
2001
Stromal cell-derived factor-1alpha (SDF-1alpha) is a potent chemoattractant for hematopoietic progenitor cells (HPC), suggesting that it could play an important role during their migration within or to the bone marrow (BM). The integrin VLA-4 mediates HPC adhesion to BM stroma by interacting with CS-1/fibronectin and VCAM-1. It is required during hematopoiesis and homing of HPC to the BM. As HPC migration in response to SDF-1alpha might require dynamic regulation of integrin function, we investigated if SDF-1alpha could modulate VLA-4 function on BM CD34(hi) cells.CD34(hi) BM cells and hematopoietic cell lines were tested for the effect of SDF-1alpha on VLA-4-dependent adhesion to CS-1/fibr…
Marine tumor vaccine carriers: structure of the molluscan hemocyanins KLH and htH.
2002
Keyhole limpet hemocyanin (KLH) is a well-established immune stimulant and hapten carrier, and Haliotis tuberculata hemocyanin (HtH) is a related product. Biologically, KLH and HtH are blue copper proteins which serve as oxygen carriers in the blood of the keyhole limpet Megathura crenulata and the abalone H. tuberculata, respectively, two marine gastropods. Both hemocyanins occur as two distinct isoforms, termed KLH1 KLH2, HtH1, and HtH2. Each of these molecules is based on a very large polypeptide chain, the subunit (molecular mass ca 400 kDa), which is folded into a series of eight globular functional units (molecular mass ca 50 kDa each). Twenty copies of this subunit form a cylindrical…
Candida bloodstream infections in intensive care units: Analysis of the extended prevalence of infection in intensive care unit study
2011
Objectives: To provide a global, up-to-date picture of the prevalence, treatment, and outcomes of Candida bloodstream infections in intensive care unit patients and compare Candida with bacterial bloodstream infection. Design: A retrospective analysis of the Extended Prevalence of Infection in the ICU Study (EPIC II). Demographic, physiological, infection-related and therapeutic data were collected. Patients were grouped as having Candida, Gram-positive, Gram-negative, and combined Candida/bacterial bloodstream infection. Outcome data were assessed at intensive care unit and hospital discharge. Setting: EPIC II included 1265 intensive care units in 76 countries. Patients: Patients in partic…
Subsynaptic Distribution, Lipid Raft Targeting and G Protein-Dependent Signalling of the Type 1 Cannabinoid Receptor in Synaptosomes from the Mouse H…
2021
Numerous studies have investigated the roles of the type 1 cannabinoid receptor (CB1) in glutamatergic and GABAergic neurons. Here, we used the cell-type-specific CB1 rescue model in mice to gain insight into the organizational principles of plasma membrane targeting and Gαi/o protein signalling of the CB1 receptor at excitatory and inhibitory terminals of the frontal cortex and hippocampus. By applying biochemical fractionation techniques and Western blot analyses to synaptosomal membranes, we explored the subsynaptic distribution (pre-, post-, and extra-synaptic) and CB1 receptor compartmentalization into lipid and non-lipid raft plasma membrane microdomains and the signalling properties.…
