Invitation to participate in a multi-center study for validation of cerebral computed tomography angiography and computed tomography perfusion in the…

In recent years commensal microorganisms are not just “passive occupants”, but important element of homeostasis. There are numerous reports documenting the composition and role of the gut, skin or vagina microbiome but the role of commensal organisms living in the lungs is relatively unknown. Pulmonary microbiome impact on the immune response of the host organism and may indicate new therapeutic directions. Lung microbiome, by modulating the expression of innate immunity genes, causes an increase in the concentration of IL-5, IL-10, IFNγ and CCL11, affects the TLR4 dependent response of pulmonary macrophages and modulate the production of antibacterial peptides contained in the mucus. It is…

202C.S.E. analgesia in active labor: effects of the intrathecal administration of l-Bupivacaine or Ropivacaine on onset and side effects

Interpleurale Katheteranalgesie

1994

Interpleural analgesia is a method of postoperative analgesia that was developed by Kvalheim and Reiestad in 1984. The main indication is postoperative pain after unilateral thoracic and upper abdominal surgery. Many authors report good analgesic effects and better postoperative lung function following cholecystectomy. There is some controversy on the effectiveness of this method after thoracic surgery. Further indications are post-traumatic pain after multiple rib fractures and chronic pain in the upper abdomen (carcinoma of the pancreas, chronic pancreatitis). The local anaesthetic of choice is bupivacaine (in concentrations of 0.25-0.75%, injection volumes of 10-40 ml, with or without ep…

Bispecific antibodies targeting tumor-associated antigens and neutralizing complement regulators increase the efficacy of antibody-based immunotherap…

2015

The efficacy of antibody-based immunotherapy is due to the activation of apoptosis, the engagement of antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity (CDC). We developed a novel strategy to enhance CDC using bispecific antibodies (bsAbs) that neutralize the C-regulators CD55 and CD59 to enhance C-mediated functions. Two bsAbs (MB20/55 and MB20/59) were designed to recognize CD20 on one side. The other side neutralizes CD55 or CD59. Analysis of CDC revealed that bsAbs could kill 4-25 times more cells than anti-CD20 recombinant antibody in cell lines or cells isolated from patients with chronic lymphocytic leukemia. The pharmacokinetics of the bsAbs was evaluate…

Platelet-derived growth factor alpha mediates the proliferation of peripheral T-cell lymphoma cells via an autocrine regulatory pathway.

2014

Peripheral T-cell lymphomas not otherwise specified (PTCL/NOS) are very aggressive tumors characterized by consistent aberrant expression of platelet-derived growth factor receptor alpha (PDGFRA). In this study, we aimed to identify the determinants of PDGFRA activity in PTCL/NOS and to elucidate the biological consequences of its activation. We observed overexpression of the PDGFRA gene by gene expression profiling in most of the tested PTCLs and confirmed the expression of PDGFRA and phospho-PDGFRA using immunohistochemistry. The integrity of the PDFGRA locus was demonstrated using several different approaches, including massive parallel sequencing and Sanger sequencing. PDGF-AA was found…

Prognostic significance of central venous-to-arterial carbon dioxide difference during the first 24 hours of septic shock in patients with and withou…

2017

IF 6.238; International audience; Objective: To investigate the prognostic significance of central venous-to-arterial carbon dioxide difference (cv-art CO2 gap) during septic shock in patients with and without impaired cardiac function.Methods: We performed a prospective cohort study in 10 French intensive care units. Patients suffering from septic shock were assigned to the impaired cardiac function group (‘cardiac group’, n=123) if they had atrial fibrillation (AF) and/or left ventricular ejection fraction (LVEF) 0.9 kPa at 12 h had a higher risk of day 28 mortality (hazard ratio=3.18; P=0.0049). Among the 59 patients in the cardiac group with mean arterial pressure (MAP) ≥65 mm Hg, centr…

PiCCO plus: monitorización cardiopulmonar mínimamente invasiva

2008

Insertion of a central venous catheter and an arterial catheter would be indicated in hemodynamically unstable or severely hypoxic patients in critical care units. In this setting, cardiorespiratory monitoring by transpulmonary thermodilution (TPTD) can be considered minimally invasive given that only a single arterial thermodilution catheter and a single central venous catheter are required to be connected to a specific monitor (the PiCCO Plus, Pulsion Medical Systems, Munich, Germany). TDTP simultaneously measures cardiac output, preloading, and cardiac function in hemodynamically unstable patients and predicts the response to volume. The technique can be managed by any health care profes…

Evaluation of stroke volume variation obtained by arterial pulse contour analysis to predict fluid responsiveness intraoperatively

2009

Background Fluid management guided by oesophageal Doppler monitor has been reported to improve perioperative outcome. Stroke volume variation (SVV) is considered a reliable clinical predictor of fluid responsiveness. Consequently, the aim of the present trial was to evaluate the accuracy of SVV determined by arterial pulse contour (APCO) analysis, using the FloTrac™/Vigileo™ system, to predict fluid responsiveness as measured by the oesophageal Doppler. Methods Patients undergoing major abdominal surgery received intraoperative fluid management guided by oesophageal Doppler monitoring. Fluid boluses of 250 ml each were administered in case of a decrease in corrected flow time (FTc) to 10%. …

How to communicate between surgeon and intensivist?

2020

Purpose of review Communication and teamwork are essential to enhance the quality of care, especially in operating rooms and ICUs. In these settings, the effective interprofessional collaboration between surgeons and intensivists impacts patients' outcome. This review discusses current opinions and evidence for improving communication strategies and the relationship between surgeons and intensivists/anesthesiologist. Recent findings Effective teamwork has been demonstrated to improve patient outcome and foster healthier relationships between professionals.With the expansion of new medical superspecialist disciplines and the latest medical developments, patient care has been put through a pr…

Healthcare-associated central nervous system infections.

2022

Purpose of review The aim of this review is to provide a practical and updated summary on healthcare-associated central nervous system infections and their management. Recent findings The term ‘healthcare-associated ventriculitis and meningitis’ has recently been coined and clinical practical guidelines have been published on the management of these nosocomial infections. Many aspects have still to be further investigated (e.g. cerebrospinal fluid biomarkers, indications for novel antibiotics, intrathecal antimicrobial regimens). Summary Clinicians should maintain a high index of suspicion for healthcare-associated central nervous system infections in patients with specific risk factors (i.…
