Baseline Ultrasound Venous Thrombosis Burden and the Risk of Post-thrombotic Syndrome in Patients With a First Acute Unprovoked Episode of Symptomatic Deep Vein Thrombosis of the Lower Limbs - The "DVT-Burden" Project -
Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT), with major consequences for patient quality of life and cost of management. Identifying patients at high risk of developing PTS could be useful for its prevention and may lead to more appropriate therapeutic strategies to reduce its incidence and severity.
Prognostic tools for predicting risk are very useful for choosing the optimum treatment and improving patient management and are a preliminary step before developing predictive models useful for determining sensitivity to treatment. At present, although several prognostic markers and models have been proposed, it is still difficult to predict who will develop a PTS or a moderate to severe PTS. The development of PTS is multifactorial and depends largely on the extent and severity of venous obstruction which supports the theory of thrombosis burden (DVT-Burden) as a potential prognostic marker for PTS. It therefore seems important to study the association between thrombosis burden and the occurrence of PTS.
The Venous Volumetric Index or VVI (Ouriel 1999) will be used for quantifying DVT-Burden. The VVI was constructed by calculating the volume from the diameter and length of 14 venous segments from the calf veins to the inferior vena cava. The VVI has been validated for its ability to discriminate between symptomatic and asymptomatic DVT and has shown superior performance to other methods for quantifying DVT.
This study aim to assess the performance of baseline DVT-burden estimated by the VVI score on ultrasound for predicting the occurrence and the severity of PTS as assessed by the Villalta scale at 6 months.
Phenomenological Explorations of the Esketamine-Induced Transient Dissociative State
Ketamine is an anaesthetic used in low doses to treat depressive disorders. A related molecule, Esketamine, has recently been launched on the market for the treatment of resistant depression. One of the side effects of ketamine, like Esketamine, is induction of transient dissociative state. Dissociation has been described as disruption in continuity of conscious thought and emotion, cognitive processes disorganisation and an alteration in self-perception and environment perception. A study of healthy volunteers receiving ketamine showed that this state was manifested by altered sensory perceptions, with increased noise sensitivity, visual distortions and altered time perception. Few studies have looked at this phenomenon in the Esketamine context. However, it is a frequent side effect. With ketamine, it has been shown that anxiety associated with dissociative experience reduces the antidepressant effect. Benzodiazepines use for anxiolytic purposes is also thought to limit the antidepressant effect.
It is necessary to explore the Esketamine induced transient dissociative state in order to clarify this state and develop therapeutic strategies. The investigators have chosen a phenomenological approach, which is the only way to evaluate consciousness contents and structures, in order to explore this state using the experiential phenomenological interview.
Strategy for Unstable Coronary Plaque in Patients Presenting to the Emergency Department for Chest Pain Suspected of Coronary Artery Disease. A Trial in Primary Prevention and Cardiovascular Risks Evaluation
Primary prevention of coronary disease and especially its major complication, inaugural myocardial infarction, is based on any prodromal symptoms identification and on risk profile establishment. About 50% of myocardial infarctions are caused by an unstable non-stenosing plaque, asymptomatic before the event since without significant reduction in coronary flow, particularly during a stress test or during stress imaging.
Study purpose is to set up, in medical emergency department, check-up unit and cardiology department, a primary prevention strategy articulated around a routine examination: calcium scoring. The latter makes it possible to categorize patients according to their risk of generating atheromatous plaques and to classify them into several risk levels (groups) according to their score: low (<40th percentile), intermediate (between the 40th percentile and the 65th percentile: group III) or high risk (>65th percentile, group IV). 18F-Na PET scan can mark unstable coronary plaques. For the intermediate risk population who would demonstrate within 6 to 18 months after first calcium score either an increase of percentile of more than 20% or an increase above 20 points of the calcium score and for high risk population, 18F-Na PET scan will be recommended and repeated 6 months later. Secondary prevention treatment will then be administered in the event of an abnormal examination.
