Article Synopsis
  • Intrinsic activation MR elastography (iMRE) uses heartbeats to evaluate tissue stiffness in focal liver lesions, aiming to better distinguish between malignant and benign types compared to extrinsic MR elastography (eMRE).
  • In a study with 55 participants, both iMRE and eMRE were performed, revealing that malignant lesions had significantly higher shear stiffness and damping ratio than benign ones, especially observed in measurements at various frequencies.
  • The effectiveness of iMRE and eMRE in differentiating lesions was quantified, with areas under the receiver operating characteristic curves (AUC) indicating strong overall diagnostic performance for both techniques, particularly with iMRE and eMRE's shear stiffness values.

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is associated with a high rate of disease recurrence following endoscopic sinus surgery (ESS). Type 2 disease is associated with a higher incidence of recurrence and is believed to impact disease resolution via interference with epithelial healing and pathogen immunity. We wished to verify if perioperative control of Type 2 inflammation with an anti-IL4/IL13 targeting monoclonal antibody and during the resolution period following surgery leads to better control of the disease long term.

Introduction: Acute kidney injury (AKI) is a frequent complication following liver transplantation (LT) that has a multifactorial etiology. While some perioperative risk factors have been associated with postoperative AKI, the impact of liver graft weight to recipient body weight ratio (GW/RBW) has been poorly explored. We hypothesized that a high GW/RBW ratio would be associated with AKI after LT.

Background: Vacuum massage, or endermotherapy, is applied to scar tissue with the primary therapeutic goal of promoting structural or physiological changes. These changes are intended to enhance pliability, enabling the skin to possess the strength and elasticity required for normal mobility. The advantage of vacuum massage compared to therapist-generated manual massage is that it provides a standardized dosage using rollers and suction valves to mobilize the tissue.

Aberrant hormone receptors regulate a wide spectrum of endocrine tumors.

Lancet Diabetes Endocrinol

November 2024

Univ Rouen Normandie, Inserm, NorDiC UMR 1239, Rouen, France; Department of Endocrinology, Diabetes and Metabolic Diseases, Rouen, France.

Aberrant G-protein coupled receptor (GPCR) expression is highly prevalent in cortisol-secreting primary bilateral macronodular adrenal hyperplasia (PBMAH) and unilateral adenomas. The aberrant expression of diverse GPCRs and their ligands play an important role in the over-function of various endocrine tumours. Examples include aberrant expression of MC2R, 5-HT4R, AVPR1A, LHCGR, and GnRHR in primary aldosteronism; GCGR, LHCGR, and 5-HT4R in phaeochromocytomas and paragangliomas; TRHR, GnRHR, GIPR, and GRP101 in pituitary somatotroph tumours; AVPR2, D2DR, and SSTR5 in pituitary corticotroph tumours; GLP1R, GIPR, and somatostatin receptors in medullary thyroid carcinoma; and SSTRs, GLP1R, and GIPR in other neuroendocrine tumours.

Article Synopsis
  • A study found that antibiotics can harm the good bacteria in our bodies and make cancer treatments less effective, particularly a type of treatment called immune checkpoint inhibitors (ICI).
  • Researchers tested a new treatment called DAV132 on healthy volunteers to see if it could help fix the issues caused by antibiotics, and it turned out to be safe and did not change antibiotic levels too much.
  • In mice tests, DAV132 helped keep the good bacteria safe and improved the effectiveness of cancer treatments compared to those given antibiotics alone. This means DAV132 might be a good way to protect the bacteria and help cancer patients who take antibiotics.
