SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study.

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling.

Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year.

Temporal Trends of Out-of-Hospital Cardiac Arrests Without Resuscitation Attempt by Emergency Medical Services.

Background: Significant improvements in survival from out-of-hospital cardiac arrest (OHCA) have been reported; however, these are based only on data from OHCA in whom resuscitation is initiated by emergency medical services (EMS). We aimed to assess the characteristics and temporal trends of OHCA without resuscitation attempt by EMS.

Methods: Prospective population-based study between 2011 and 2016 in the Greater Paris area (6.

Timing of surgery following SARS-CoV-2 infection: an international prospective cohort study.

Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020.

Proximal Protein Interaction Landscape of RAS Paralogs.

RAS proteins (KRAS, NRAS and HRAS) are frequently activated in different cancer types (e.g., non-small cell lung cancer, colorectal cancer, melanoma and bladder cancer).

Impact of Coronary Lesion Stability on the Benefit of Emergent Percutaneous Coronary Intervention After Sudden Cardiac Arrest.

Background: Conflicting data exist regarding the benefit of urgent coronary angiogram and percutaneous coronary intervention (PCI) after sudden cardiac arrest, particularly in the absence of ST-segment elevation. We hypothesized that the type of lesions treated (stable versus unstable) influences the benefit derived from PCI.

Methods: Data were taken between May 2011 and 2014 from a prospective registry enrolling all sudden cardiac arrest in Paris and suburbs (6.

Promoter Mutation as an Independent Prognostic Marker for Poor Prognosis MAPK Inhibitors-Treated Melanoma.

Although the development of mitogen-activated protein kinase (MAPK) inhibitors has greatly improved the prognosis of cutaneous melanomas, the identification of molecular indicators for mutated patients at risk of early progression remains a major issue. Using an amplicon-based next-generation-sequencing (NGS) assay that targets cancer-related genes, we investigated co-occurring alterations in 89 melanoma samples. We analyzed both their association with clinicopathological variables and clinical significance in terms of progression-free survival (PFS) and overall survival (OS) according to genotyping.

Out-of-hospital cardiac arrest during the COVID-19 pandemic in Paris, France: a population-based, observational study.

Background: Although mortality due to COVID-19 is, for the most part, robustly tracked, its indirect effect at the population level through lockdown, lifestyle changes, and reorganisation of health-care systems has not been evaluated. We aimed to assess the incidence and outcomes of out-of-hospital cardiac arrest (OHCA) in an urban region during the pandemic, compared with non-pandemic periods.

Methods: We did a population-based, observational study using data for non-traumatic OHCA (N=30 768), systematically collected since May 15, 2011, in Paris and its suburbs, France, using the Paris Fire Brigade database, together with in-hospital data.

Low rates of immediate coronary angiography among young adults resuscitated from sudden cardiac arrest.

Aim: Coronary artery disease (CAD) has recently been emphasized as a major cause of sudden cardiac arrest (SCA) in young adults. We aim to assess the rate of immediate coronary angiography performance in young patients resuscitated from SCA.

Methods: From May 2011 to May 2017, all cases of out-of-hospital SCA aged 18-40 years alive at hospital admission were prospectively included in 48 hospitals of the Great Paris area.

Temporal trends in the use of targeted temperature management after cardiac arrest and association with outcome: insights from the Paris Sudden Death Expertise Centre.

Purpose: Recent doubts regarding the efficacy may have resulted in a loss of interest for targeted temperature management (TTM) in comatose cardiac arrest (CA) patients, with uncertain consequences on outcome. We aimed to identify a change in TTM use and to assess the relationship between this change and neurological outcome.

Methods: We used Utstein data prospectively collected in the Sudden Death Expertise Center (SDEC) registry (capturing CA data from all secondary and tertiary hospitals located in the Great Paris area, France) between May 2011 and December 2017.

Extracorporeal cardiopulmonary resuscitation in out-of-hospital cardiac arrest: a registry study.

Aims: Out-of-hospital cardiac arrest (OHCA) without return of spontaneous circulation (ROSC) despite conventional resuscitation is common and has poor outcomes. Adding extracorporeal membrane oxygenation (ECMO) to cardiopulmonary resuscitation (extracorporeal-CPR) is increasingly used in an attempt to improve outcomes.

Methods And Results: We analysed a prospective registry of 13 191 OHCAs in the Paris region from May 2011 to January 2018.

FKBP4 connects mTORC2 and PI3K to activate the PDK1/Akt-dependent cell proliferation signaling in breast cancer.

Among the FKBP family members, FKBP4 has been described to have a potential role in tumorigenesis, and as a putative tissue marker. We previously showed that FKBP4, an HSP90-associated co-chaperone, can elicit immune response as a tumor-specific antigen, and are overexpressed in breast cancer. In this study, we examined how loss of FKBP4 affect breast cancer progression and exploited protein interactomics to gain mechanistic insight into this process.

Implantable cardioverter defibrillator therapy for primary prevention of sudden cardiac death in the real world: Main findings from the French multicentre DAI-PP programme (pilot phase).

This review summarizes the main findings of the French multicentre DAI-PP pilot programme, and discusses the related clinical and research perspectives. This project included retrospectively (2002-2012 period) more than 5000 subjects with structural heart disease who received an implantable cardioverter defibrillator (ICD) for primary prevention of sudden cardiac death, and were followed for a mean period of 3 years. The pilot phase of the DAI-PP programme has provided valuable information on several practical and clinically relevant aspects of primary prevention ICD implantation in the real-world population, which are summarized in this review.

Protein interactions study through proximity-labeling.

: The proteome is a dynamic system in which protein-protein interactions play a crucial part in shaping the cell phenotype. However, given the current limitations of available technologies to describe the dynamic nature of these interactions, the identification of protein-protein interactions has long been a major challenge in proteomics. In recent years, the development of BioID and APEX, two proximity-tagging technologies, have opened-up new perspectives and have already started to change our conception of protein-protein interactions, and more generally, of the proteome.

[New approaches for protein-protein interaction study].

The proteome is a dynamic system in which protein-protein interactions play a crucial role to model together the cellular phenotype. However, given the inherent limitation of the available technologies to depict the dynamic nature of these interactions, identify protein-protein interaction has for a long time represented an important challenge in proteomic. The recent development of BioID and APEX, two proximity-dependent labeling technologies, opens today new perspectives and yet start changing our vision of protein-protein interaction, and more globally our vision of the proteome.

Ambulance Density and Outcomes After Out-of-Hospital Cardiac Arrest.

Background: In out-of-hospital cardiac arrest (OHCA), geographic disparities in outcomes may reflect baseline variations in patients' characteristics but may also result from differences in the number of ambulances providing basic life support (BLS) and advanced life support (ALS). We aimed at assessing the association between allocated ambulance resources and outcomes in OHCA patients in a large urban community.

Methods: From May 2011 to January 2016, we analyzed a prospectively collected Utstein database for all OHCA adults.

Early in-hospital management of cardiac arrest from neurological cause: Diagnostic pitfalls and treatment issues.

Purpose: To explore diagnostic pitfalls and treatment issues in out-of-hospital cardiac arrest of neurological cause (OHCA-NC).

Methods: Retrospective analysis of all consecutive patients from the Paris Sudden Death Expertise Centre (France) registry from May 2011 to September 2015 presenting with a sustained return of spontaneous circulation (ROSC) at hospital admission and a final diagnosis of OHCA-NC. Description of the early diagnostic check-up performed to identify the cause of cardiac arrest.

Age and benefit of early coronary angiography after out-of-hospital cardiac arrest in patients presenting with shockable rhythm: Insights from the Sudden Death Expertise Center registry.

Background: Little is known about the association between provision of post-resuscitation care and prognosis of out-of-hospital cardiac arrest (OHCA) in elderly patients. Previous studies have suggested futility after 65 years of age.

Objectives: We aimed to evaluate the association of early coronary angiogram (CAG) followed if necessary by percutaneous coronary intervention (PCI), with favorable outcome after OHCA among elderly patients, compared to younger patients.

Characteristics and clinical assessment of unexplained sudden cardiac arrest in the real-world setting: focus on idiopathic ventricular fibrillation.

Aims: Recent studies have shown that in more than half of apparently unexplained sudden cardiac arrests (SCA), a specific aetiology can be unmasked by a careful evaluation. The characteristics and the extent to which such cases undergo a systematic thorough investigation in real-life practice are unknown.

Methods And Results: Data were analysed from an ongoing study, collecting all cases of out-of-hospital cardiac arrest in Paris area.

Should We Perform an Immediate Coronary Angiogram in All Patients After Cardiac Arrest?: Insights From a Large French Registry.

Objectives: This study sought to assess the relationship between an immediate invasive strategy and survival after an out-of-hospital cardiac arrest (OHCA) of presumed cardiac cause, according to prognosis evaluated on hospital arrival.

Background: An immediate coronary angiogram (CAG) may be associated with better outcome after OHCA in neurologically preserved patients but could be futile in other cases.

Methods: From May 2011 to May 2015, we collected data for all patients admitted in hospital after OHCA in Paris and its suburbs (France).

Detection of known and novel ALK fusion transcripts in lung cancer patients using next-generation sequencing approaches.

Rearrangements of the anaplastic lymphoma kinase (ALK) gene in non-small cell lung cancer (NSCLC) represent a novel molecular target in a small subset of tumors. Although ALK rearrangements are usually assessed by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), molecular approaches have recently emerged as relevant alternatives in routine laboratories. Here, we evaluated the use of two different amplicon-based next-generation sequencing (NGS) methods (AmpliSeq and ArcherFusionPlex) to detect ALK rearrangements, and compared these with IHC and FISH.

Pseudomonas aeruginosa ExlA and Serratia marcescens ShlA trigger cadherin cleavage by promoting calcium influx and ADAM10 activation.

Pore-forming toxins are potent virulence factors secreted by a large array of bacteria. Here, we deciphered the action of ExlA from Pseudomonas aeruginosa and ShlA from Serratia marcescens on host cell-cell junctions. ExlA and ShlA are two members of a unique family of pore-forming toxins secreted by a two-component secretion system.
