Long-Term Outcomes of Fenestrated Aortic Endovascular Repair in Patients Bearing JuxtaRenal Aneurysms.

Background: Fenestrated endografts have been a safe and effective solution in our institution for patients with juxtarenal abdominal aortic aneurysms (AAAs) that were not candidates for conventional repair and had suitable anatomy. The objective of our study was to evaluate the long-term outcomes of these interventions.

Methods: Between September 2005 and December 2021, this study included all the patients bearing juxtarenal aneurysm electively treated with a fenestrated endograft.

Design of a simplified cranial substitute with a modal behavior close to that of a human skull.

Individuals exposed to the propagation of shock waves generated by the detonation of explosive charges may suffer Traumatic Brain Injury. The mechanism of cranial deflection is one of many hypotheses that could explain the observed brain damage. To investigate this physical phenomenon in a reproducible manner, a new simplified cranial substitute was designed with a mechanical response close to that of a human skull when subjected to this type of loading.

Two-Year Results on Real-World Fenestrated or Branched Endovascular Repair for Complex Aortic Abdominal Aneurysm in France.

Purpose: To describe and compare mid-term outcomes from 2 real-world data collection efforts on fenestrated and branched endovascular aortic repair (fbEVAR) for complex abdominal aortic aneurysms (AAAs) in France and to evaluate the potential of health care databases for long-term post-market surveillance (PMS) and continued reimbursement approval.

Methods: Two real-world studies were conducted in France: a retrospective health care database study (SNDS) and a prospective clinical study. In the SNDS study, data from implantation and/or hospital stays occurring during follow-up were extracted for all patients treated with the study devices from April 2012 to December 2018.

Femoro-Popliteal Bypass Infection: A Case Report.

Cardiovascular infections are the most severe and potentially lethal among the persistent focalized infections. While aortic infections on aneurysms or prostheses are well-known, with specific complications (risk of fatal rupture), new non-aortic vascular infections are increasingly being described thanks to the emerging use of 18-fluorodeoxyglucose positron emission tomography (F-FDG PET-scan). Here, we describe an infection of a femoro-popliteal bypass that would not have been diagnosed without the use of PET-scan.

Design of a CMOS image sensor pixel with embedded polysilicon nano-grating for near-infrared imaging enhancement.

Complementary metal-oxide semiconductor (CMOS) image sensor sensitivity in the near-infrared spectrum is limited by the absorption length in silicon. To deal with that limitation, we evaluate the implementation of a polysilicon nano-grating inside a pixel, at the transistor gate level of a 90 nm standard CMOS process, through opto-electrical simulations. The studied pixel structure involves a polysilicon nano-grating, designed with the fabrication layer of the transistor gate, which does not require any modifications in the process flow.

A New Anthropomorphic Mannequin for Efficacy Evaluation of Thoracic Protective Equipment Against Blast Threats.

Exposure to blast is one of the major causes of death and disability in recent military conflicts. Therefore, it is crucial to evaluate the protective capability of the ballistic-proof equipment worn by soldiers against the effects of blast overpressure (i.e.

Parallel evolution of morphological traits and body shape in littoral and pelagic brook charr, Salvelinus fontinalis, along a gradient of interspecific competition.

The parallel evolution of similar ecotypes in response to comparable environmental conditions is believed to reveal the importance of divergent selection in phenotypic diversifying processes. Systems characterized by the presence of multiple replicate populations expressing resource polymorphism thus provide an ideal opportunity to address the occurrence and factors affecting the parallel evolution of ecotypes. Previous studies have shown that brook charr (Salvelinus fontinalis) exhibit resource polymorphism in some Canadian Shield lakes, where a littoral ecotype feeds mainly on zoobenthos and a pelagic ecotype feeds mostly on zooplankton.

Modeling, Simulation Methods and Characterization of Photon Detection Probability in CMOS-SPAD.

Single-Photon Avalanche Diodes (SPAD) in Complementary Metal-Oxide Semiconductor (CMOS) technology are potential candidates for future "Light Detection and Ranging" (Lidar) space systems. Among the SPAD performance parameters, the Photon Detection Probability (PDP) is one of the principal parameters. Indeed, this parameter is used to evaluate the SPAD sensitivity, which directly affects the laser power or the telescope diameter of space-borne Lidars.

Extraction of acceptor concentration map from EBIC experiments.

Controlling two dimensional doping distributions is an important benefit in order to check processed substrates or specific devices. To achieve this purpose, a new methodology is proposed in order to obtain qualitative maps of acceptor concentration from one EBIC image. Analytical models are used to help in defining the best experimental condition and to check the validity of the approach, and a TCAD simulation is performed on a realistic structure and shows promising results.

Impact of sex on the management and outcome of aortic stenosis patients.

Objective: The aim of this study was to assess the impact of sex on the management and outcome of patients according to aortic stenosis (AS) severity.

Introduction: Sex differences in the management and outcome of AS are poorly understood.

Methods: Doppler echocardiography data of patients with at least mild-to-moderate AS [aortic valve area (AVA) ≤1.

Does ecological release from distantly related species affect phenotypic divergence in brook charr?

Ecological opportunity occurs when a resource becomes available through a decrease of interspecific competition and another species colonizes the vacant niche through phenotypic plasticity and intraspecific competition. Brook charr exhibit a resource polymorphism in some Canadian Shield lakes, where a littoral ecotype feeds mainly on zoobenthos and a pelagic ecotype feeds mostly on zooplankton. The objectives of this study were to test that (i) resource polymorphism is common in these brook charr populations, (ii) the presence creek chub and white sucker, two introduced species competing with brook charr for littoral resources, will decrease the phenotypic divergence between the two brook charr ecotypes, and (iii) the ecological release from introduced species will increase population and/or individual niche widths in brook charr.

STABILISE Technique for a Non-A Non-B Acute Aortic Dissection in Marfan Syndrome.

A 35-year-old man, with a deep pectus excavatum due to a Marfan syndrome treated 9 years before for an acute type A dissection involving only the aortic arch, by a Bentall surgery, was admitted for acute chest pain. Computed tomography (CT) scan showed an acute type non-A non-B dissection extending to the iliac. After 5 days with strict arterial blood pressure management, the patient had recurrent refractory chest pain and a hybrid technique associating full supra-aortic vessels debranching and STABILISE technique during the same procedure was performed.

Protocol of supra-visceral aortic ischemic preconditioning for open surgical repair of thoracoabdominal aortic aneurysm : The EPICATA study (Evaluation of the Efficacy of Ischemic PreConditioning on morbidity and mortality in open ThoracoAbdominal Aortic surgery).

Background: Open surgical repair (OSR) for thoracoabdominal aortic aneurysms (TAA) is associated with a high pulmonary and renal morbidity rate. Ischemic preconditioning (IPC) is a mechanism of protection against the deleterious effects of ischemia-reperfusion. To our knowledge IPC has never been tested during OSR for TAA.

Material And Method: All the patients surgically managed in our center for an aortic infection were retrospectively analyzed. The primary endpoint was the intra-hospital mortality, secondary outcomes were limb salvage, persistent or recurrent infection, prosthetic graft patency, and long-term survival.

Electrical Characterization of the Backside Interface on BSI Global Shutter Pixels with Tungsten-Shield Test Structures on CDTI Process.

A new methodology is presented using well known electrical characterization techniques on dedicated single devices in order to investigate backside interface contribution to the measured pixel dark current in BSI CMOS image sensors technologies. Extractions of interface states and charges within the dielectric densities are achieved. The results show that, in our case, the density of state is not directly the source of dark current excursions.

Leakage Current Non-Uniformity and Random Telegraph Signals in CMOS Image Sensor Floating Diffusions Used for In-Pixel Charge Storage.

The leakage current non-uniformity, as well as the leakage current random and discrete fluctuations sources, are investigated in pinned photodiode CMOS image sensor floating diffusions. Different bias configurations are studied to evaluate the electric field impacts on the FD leakage current. This study points out that high magnitude electric field regions could explain the high floating diffusion leakage current non-uniformity and its fluctuation with time called random telegraph signal.

CMOS Image Sensors and Plasma Processes: How PMD Nitride Charging Acts on the Dark Current.

Plasma processes are known to be prone to inducing damage by charging effects. For CMOS image sensors, this can lead to dark current degradation both in value and uniformity. An in-depth analysis, motivated by the different degrading behavior of two different plasma processes, has been performed in order to determine the degradation mechanisms associated with one plasma process.

Linking fisheries to land use: How anthropogenic inputs from the watershed shape fish habitat quality.

Aquatic ecosystems are increasingly threatened by anthropogenic stressors, both at local and larger scales. For instance, runoff from intensively cultivated areas leads to higher nutrient and sediment concentrations deteriorating water quality, which potentially trigger trophic state changes. Unfortunately, we have a poor understanding of the complex relationships linking water quality degradation and different ecosystem components.

Alternative host identity and lake morphometry drive trematode transmission in brook charr.

Both biotic and abiotic factors have been invoked to explain the large variations observed in the prevalence and abundance of parasites in aquatic ecosystems. However, we have only a poor knowledge of the potential interplay among these factors in natural systems. It is, therefore, important to analyze the effects of multiple potential environmental drivers together to get an integrated view of their influence on the prevalence and abundance of parasites.

French Guidelines for the Management of Ambulatory Endovascular Procedures for Lower Extremity Peripheral Artery Disease.

Background: Ambulatory hospitalization for endovascular repair of lower extremity peripheral arterial disease (PAD) could be a real opportunity to respond to the burden of PAD, to reduce costs, and to improve patients' empowerment. The French Society of Vascular and Endovascular Surgery (SCVE) established guidelines to facilitate the development of ambulatory hospitalization in France.

Methods: In 2017, we used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and MEDLINE database to conduct a systematic review of available literature.

Fenestrated endovascular aneurysm repair and open surgical repair for the treatment of juxtarenal aortic aneurysms.

Objective: The objective of this study was to compare surgical risk and early and late mortality of patients treated for anatomically classified juxtarenal aortic aneurysms (JRAs) by fenestrated endovascular aneurysm repair (F-EVAR) or open surgical repair (OSR) during a period when the two treatments were available and to validate an institutional algorithm for JRA repair.

Methods: We retrospectively included all patients treated electively in our center between January 2005 and December 2015 for JRAs classified into three anatomic categories, excluding suprarenal aneurysms. Lee score and American Society of Anesthesiologists (ASA) class evaluated preoperative surgical risk.
