Improving the reliability of small- and wide-angle X-ray scattering measurements of anisotropic precipitates in metallic alloys using sample rotation.

Nanometric precipitates in metallic alloys often have highly anisotropic shapes. Given the large grain size and non-random texture typical of these alloys, performing small- and wide-angle X-ray scattering (SAXS/WAXS) measurements on such samples for determining their characteristics (typically size and volume fraction) results in highly anisotropic and irreproducible data. Rotations of flat samples during SAXS/WAXS acquisitions are presented here as a solution to these anisotropy issues.

Early perioperative quality of recovery after hip and knee arthroplasty: a retrospective comparative cohort study.

Purpose: Increasing our knowledge about postoperative global Quality-Of-Recovery (QoR) after THA and TKA is important to improve perioperative medicine, in particular for preoperative patient information and benchmarking of postoperative patient status.

Methods: This study is a single centre, retrospective cohort study of prospectively collected data, conducted in Strasbourg University Hospital, Strasbourg, France. The main outcome was the modified French version of the QoR-15 (mQoR-15F) score monitored preoperatively, at postoperative day one, three, 14 and 28.

Optimal Timing of Coronary Artery Bypass Grafting in Haemodynamically Stable Patients after Myocardial Infarction.

During the acute phase of myocardial infarction, the culprit artery must be revascularized quickly with angioplasty. Surgery then completes the procedure in a second stage. If emergency surgery is performed, the resulting death rate is high; 15-20% of patients are operated on within the first 48 h after the myocardial infarction.

Potential interactions between Mesolithic hunter-gatherers and Neolithic farmers in the Western Mediterranean: The geochronological data revisited.

In the Western Mediterranean, the Neolithic mainly developed and expanded during the sixth millennium BCE. In these early phases, it generally spread through the displacement of human groups, sometimes over long distances, as shown, for example, by the Impressa sites documented on the northern shores. These groups then settled new territories which they gradually appropriated and exploited.

Failure to rescue in patients with distal pancreatectomy: a nationwide analysis of 10,632 patients.

Background: FTR appears as a major cause of postoperative mortality (POM). Hospital volume has an impact on FTR in pancreatic surgery but no study has investigated this relationship more specifically in DP.

Methods: We analysed patients with DP between 2009 and 2018 through a nationwide database.

Effects of body composition profiles on oncological outcomes and postoperative intraabdominal infection following colorectal cancer surgery.

Background: Anthropometric data as prognostic factors of colorectal cancer are promising but contradictory. The aim of this study was to assess the preoperative body composition profiles as predictive factors for postoperative, oncologic, and inflammation outcomes.

Objectives: We sought to assess the impact of body composition profiles on short- and long-term outcomes and on postoperative inflammatory response in a clinical setting for patients following curative intent surgery for colorectal cancer.

Early Neolithic (ca. 5850-4500 cal BC) agricultural diffusion in the Western Mediterranean: An update of archaeobotanical data in SW France.

Farming economy was first introduced to the coastal areas of Southern France by Impressa groups (ca. 5850-5650 cal BC), originating from Italy, and subsequently spread to the hinterland by Cardial/Epicardial communities (ca. 5400-4500 cal BC).

Radiomic feature reproducibility in contrast-enhanced CT of the pancreas is affected by variabilities in scan parameters and manual segmentation.

Objectives: This study aims to measure the reproducibility of radiomic features in pancreatic parenchyma and ductal adenocarcinomas (PDAC) in patients who underwent consecutive contrast-enhanced computed tomography (CECT) scans.

Methods: In this IRB-approved and HIPAA-compliant retrospective study, 37 pairs of scans from 37 unique patients who underwent CECTs within a 2-week interval were included in the analysis of the reproducibility of features derived from pancreatic parenchyma, and a subset of 18 pairs of scans were further analyzed for the reproducibility of features derived from PDAC. In each patient, pancreatic parenchyma and pancreatic tumor (when present) were manually segmented by two radiologists independently.

Diaphragmatic paralysis in young children: A literature review.

Diaphragmatic paralysis (DP) is a rare cause of respiratory distress in young children. In the first years of life, the main cause is phrenic nerve injury after cardiothoracic surgery or obstetrical trauma. DP usually presents as respiratory distress.

Short-term reproducibility of radiomic features in liver parenchyma and liver malignancies on contrast-enhanced CT imaging.

Purpose: To evaluate the short-term reproducibility of radiomic features in liver parenchyma and liver cancers in patients who underwent consecutive contrast-enhanced CT (CECT) with intravenous iodinated contrast within 2 weeks by chance.

Methods: The Institutional Review Board approved this HIPAA-compliant retrospective study and waived the requirement for patients' informed consent. Patients were included if they had a liver malignancy (liver metastasis, n = 22, intrahepatic cholangiocarcinoma, n = 10, and hepatocellular carcinoma, n = 6), had two consecutive CECT within 14 days, and had no prior or intervening therapy.
