Brain-injured Patients Extubation Readiness Study

Severe brain-injured patients need mechanical ventilation with tracheal intubation. After treatment of the acute neurological condition, weaning of the mechanical ventilation has to be initiated notably to prevent ventilator associated pneumonia and others complications. Nevertheless, extubation failure is very common in this population due to residual neurological impairment with airway control alteration. Guidelines about weaning of mechanical ventilation and extubation exclude brain-injured patients with a residual impaired consciousness. In 2017, a simple and pragmatic extubation readiness clinical score was validated in a prospective observational cohort study of 140 brain injured patients. (Godet et al. Anesthesiology. 2017 Jan;126(1):104-114) In this study, brain injured patients with residual impaired consciousness who succeeded a spontaneous breathing trial were extubated. In multivariate analysis, 4 clinical elements were associated with extubation success. A prediction score was determined using the odds ratio such as followed : 1. Deglutition: 3 points if present 2. Gag reflex: 4 points if present 3. Cough: 4 points if present 4. CRS-R Score, visual item > 2, 3 points if present, 1 point if not For a cut-off value of 9, extubation failure could be predicted with a sensibility of 84%, a specificity of 75%, a positive predictive value of 89% and a negative predictive value of 66%. In order to participate, brain-injured patients will have to succeed a spontaneous breathing trial and meet all inclusion criteria, including not being able to obey to simple orders without sedation. Using a stepped wedge randomisation process with intensive care units as clusters, patients will be weaned and extubated under usual care or using the extubation readiness clinical score. The authors' hypothesis is that this clinical score will allow physicians to extubate patients at the right time interval and prevent extubation failure in this frail population.

VIRTUOSE : Efficiency of Sildenafil on the Absolute Claudication Distance of Peripheral Arterial Disease Patients With Intermittent Claudication.

Experimental design A Phase III, National, Multicentre, Prospective, Randomised, Double Blind, placebo-controlled clinical trial with two parallel groups. Eligible patients will be randomised in two groups: - Experimental group Sildenafil citrate 140 mg/day (single morning oral dose of 140 mg) for a total duration of 24 weeks. - Control group Placebo (single morning oral dose) for a total duration of 24 weeks. Treatment will be proposed in addition to optimal treatment (Antiplatelet / Direct Oral Anticoagulant + Lipid Lowering Drugs + AT2 antagonists / ACE Inhibitors; unless contra-indicated) + advice to walk. The experimental drug will be delivered for a 4 weeks treatment period. Phone contact will be carried out at 7 and 14 days focusing on tolerance, compliance and eventual side effects. First follow up visit at week 4 will focus on tolerance, compliance and side effects. If no major side effect is found, the study drug will be delivered for an additional 8 weeks. Phone contact will be carried out at 8 weeks focusing on tolerance, compliance and eventual side effects. Patients will be evaluated at week 12 (second follow-up visit) for persistent or non-persistent indication for revascularization and considered for revascularization if needed. In parallel, attention will be given to tolerance, compliance and eventual side effects. If no major side effect is found, the study drug will be delivered for an additional 12 weeks period. Phone contact will be carried out at weeks 16 and 20 focusing on tolerance, compliance and eventual side effects. Third and fourth follow-up visits are scheduled at week 24 (end of treatment) and week 48 (24 weeks after the end of experimental drugs). Perspectives - Improving quality of life of patients suffering a chronic debilitating disease is a major issue not only in vascular medicine. - It is expected that the treatment may help patients change from a vicious circle (Pain > inactivity > disease progression > pain > increased morbi-mortality) to a virtuous circle (no Pain > improved ability for activity > collateral vessel development > slowing of disease progression > decreased morbi-mortality ) - We expect that half of the patients that fulfil inclusion criteria will be sufficiently improved not to require surgery anymore even 24 weeks after the end of the drug as a result of this virtuous circle.

De-escalation Immunotherapy mAintenance Duration Trial for Stage IV Lung Cancer Patients With Disease Control After Chemo-immunotherapy Induction

This is a phase II-III randomized, open-labelled, multicentre study for NSCLC patients who are naive of treatment for advanced disease. Patients will be given first-line chemotherapy + pembrolizumab: platinum doublet for at least 3 cycles, either paclitaxel-carboplatin for patient with SCC or 3 cycles of pemetrexed-platinum salt followed by 2 cycles of pemetrexed and 6 cycles of pembrolizumab. Only patients with disease control, confirmed at 6 months (27-weeks) without drug-related toxicity imposing treatment discontinuation will be randomized 1:1 either to continuation of pembrolizumab (± pemetrexed for non-SCC) until disease progression or unacceptable toxicity or 2 years, or observation (± pemetrexed for non-SCC). Patients will be stratified by performance status (0 versus 1), histology (SCC versus non-SCC), PD-L1 (PD-L1 < 1% versus 49%≥PD-L1 ≥ 1% versus PD-L1>49%), sex and response at randomization (partial response versus stabilisation).

Screening for Occult Malignancy in Patients with Unprovoked Venous Thromboembolism

The identification of subgroups of patients at high risk of cancer might enable more efficient screening strategies for early detection of cancer. Venous thromboembolism (VTE) can be the first manifestation of an occult cancer. All tumor sites may be involved. In an individual patient-level data meta-analysis (IPDMA), it was reported a 1-year prevalence of occult cancer of 5.2% (95%CI 4.1-6.5) among patients presenting with unprovoked VTE. Two recent multicenter randomized controlled trials (e.g. SOME (Canada) and MVTEP (France) trials) failed to demonstrate that extensive cancer screening strategies diagnosed more cancers, more early stage tumors, or improved cancer-related mortality in comparison with a more limited screening strategy. However, the main limitation of these studies was the twice lower than expected overall incidence of occult cancer diagnosis in unselected patients with unprovoked VTE, which limited the statistical power. In the IPDMA, it was also reported that the 1-year period prevalence of occult cancer was 7-fold higher in patients aged ≥ 50 (6.8%; 95%CI 5.6-8.3) as compared with those < 50 years (1.0%; 95%CI 0.5-2.3). Moreover, in the MVTEP trial, the incidence of missed cancers over a 2-years follow-up period was significantly lower in patients randomized to a 18F-Fluorodeoxyglucose Positron Emission/Computed Tomography (FDG-PET/CT) screening strategy. Thus, the most promising diagnostic modality for occult cancer screening seems to be FDG-PET/CT. FDG-PET/CT which allows a one-stop whole-body imaging, is routinely used for the diagnosis, staging and restaging of various cancers. The MVTEP2 Trial seeks to determine if among higher risk patients (≥ 50 year-old) with a first unprovoked VTE, a cancer screening strategy including a FDG-PET/CT decreases the number of missed occult cancers detected over a 1-year follow-up period as compared with a limited screening alone.

Can Nephrocheck™ Predict the Reversibility of Early, Acute Kidney Injury During Septic Shock?

Patients with septic shock in the intensive care unit have an elevated risk of developing acute kidney injury (AKI). AKI is an independent factor for mortality. Interventions that limit the worsening of renal function might have an impact on the mortality rate in these patients. Given the absence of validated pharmacological treatments for limiting the progression of AKI or for accelerating recovery from AKI, early intervention and the restoration of the glomerular filtration rate (GFR) in this context of hemodynamic change during the initial phase of septic shock might improve the patients' prognosis. One major challenge is therefore how to determine whether or not the AKI is reversible. The best-studied biomarkers (NGAL and KIM 1) have little discriminant power in septic patients because of their poor specificity or unsuitable kinetics for very early diagnosis. The combination of urine assays for tissue inhibitor of metalloproteinase 2 (TIMP2) and insulin-like growth factor binding protein 7 (IGFBP7) has shown good diagnostic performance for the very early detection of the risk of developing AKI in the following 12 hrs. Urine levels of these two markers specifically reflect damage to kidney tubules. Moreover, the levels appear to be strongly correlated with the severity of tubule damage. Thus, one can reasonably hypothesize that measurement of these markers in the very early stages of septic shock might determine the presence and severity of kidney tubule damage. A threshold (yet to be defined) would help to differentiate between (i) transient, non-severe injury and (ii) injury that is already too severe to be reversible.
