Necrotizing enterocolitis (NEC) remains a devastating disease that affects the gastrointestinal tract of the preterm infant. Volatile organic compounds (VOCs) have emerged as a non-invasive biomarker in many diseases. We hypothesized that fecal VOC profiles would be significantly different between control and NEC pups in a NEC mouse model. Experimental NEC was induced in five-day-old mice. Breastfed and formula-fed control groups were also studied. After four days, pups were euthanized and intestines were H&E stained and blindly scored. Stool microbiome analysis was performed via 16S rRNA sequencing. VOC analysis was assessed by the Cyranose 320 eNose device and p<0.05 was significant. NEC pups had severe intestinal injury when compared to controls. Microbiome analysis showed that both control groups had significantly higher microbial diversity and relative abundance of Lactobacillus than NEC, and lower relative abundance of Escherichia. Fecal VOC profile for NEC pups was significantly different from controls. Experimental NEC was associated with intestinal dysbiosis. Fecal VOC analysis by the Cyranose 320 eNose device can discriminate NEC pups from both breastfed and formula-fed controls. Further research is warranted to establish whether fecal VOCs can be used as a biomarker or predictive algorithm to diagnose NEC.Experimental NEC was associated with intestinal dysbiosis.

Its activation is associated with an exaggeration of cell proliferation with an increase in repair capacity resulting in increased radioresistance. On cardiac tissues, HER2 receptor activation plays a cardio-protective role. Trastuzumab, the first anti-HER2 drug used to treat patients with breast cancer overexpressing HER2 receptor , inhibits the cascade of reactions resulting in the proliferation of tumor cells, thus restoring cellular radiosensitivity. However, the combination of Trastuzumab with radiation therapy also removes HER2 receptor cardio-protective role on myocardial cells which increases the risk of cardiotoxicity. Thus, the concomitant association of these two modalities has long been a subject of controversy. Recent advances in radiation therapy technology and early detection of cardiac injury may limit the cardiotoxicity of this combination. Through this review, we developed the biological basis and the benefit-risk of concomitant combination of radiotherapy and Trastuzumab in adjuvant treatment of breast cancers overexpressing HER2 and we discuss the modalities of its optimization.The reform of medical residency introduced in 2017 established the position of Junior Doctor, for its last phase, called the consolidation phase. Its goal is the increasing and supervised autonomy of the resident, in order to better support the transition toward senior practitioner. It appears necessary to define proper guidelines on the status and the specific role of Junior Doctor in medical oncology, in order to help the implementation of the reform of the 3rd cycle. This document is the result of a collaboration between AERIO and CNEC, that respectively represent medical oncology residents and university teachers. It aims to advise and guide local practices, without being compulsory, before the arrival of the first Junior Doctors in November 2021. It explains the Junior Doctors' principal jobs consultation, multidisciplinary meeting, day clinic, hospitalization, clinical research, quality policy and teaching. Ischemia/reperfusion of the intestine often leads to distant organ injury, but the mechanism of intestinal ischemia/reperfusion-induced renal dysfunction is still not clear. The present study aimed to investigate the mechanisms of acute renal damage after intestinal ischemia/reperfusion challenge and explore the role of released high-mobility group box-1 in this process. Intestinal ischemia/reperfusion was induced in male Sprague-Dawley rats by clamping the superior mesenteric artery for 1.5 hours. At different reperfusion time points, anti-high-mobility group box-1 neutralizing antibodies or ethyl pyruvate were administered to neutralize or inhibit circulating high-mobility group box-1, respectively. Significant kidney injury was observed after 6 hours of intestinal reperfusion, as indicated by increased serum levels of urea nitrogen and creatinine, increased expression of neutrophil gelatinase-associated lipocalin, interleukin-6, and MIP-2, and enhanced cell apoptosis, as indicated by cleaved caspase injury. https://www.selleckchem.com/products/Cryptotanshinone.html High-mobility group box-1 neutralization/inhibition might serve as a pharmacological intervention strategy for these pathophysiological processes.These results suggested that high-mobility group box-1 signaling regulated endoplasmic reticulum stress and promoted intestinal ischemia/reperfusion-induced acute kidney injury. High-mobility group box-1 neutralization/inhibition might serve as a pharmacological intervention strategy for these pathophysiological processes. Bile leaks occurring after complex liver resection and lasting >1 week (grade B) usually are managed by means of invasive cholangiography either endoscopic or percutaneous, with a substantial risk of procedure-related complications. The aim of this study was to investigate the ability of gadoxetic acid disodium-enhanced magnetic resonance cholangiography to detect postoperative biliary leaks and avoid invasive cholangiography in case of peripheral location of the fistula. Patients with grade B biliary leak after complex liver resection from January 2018 to March 2020 underwent magnetic resonance cholangiography to guide the management of the leak (study group). The primary endpoint was the ability of magnetic resonance cholangiography to reduce the need for invasive cholangiography with respect to similar posthepatectomy leaks collected in the previous 2 years and approached with upfront invasive cholangiography (controls). A series of in-hospital outcomes also were compared. Out of 533 liver resections, 11 study patients versus 11 control patients with grade B leaks were compared.
