Abstract: The present invention relates to a method for predicting neurodegenerative decline and/or its severity for a patient, especially of cognitive impairment (CI). Strokes and Parkinson's disease are frequently associated with occurrence of long-term cognitive impairment or dementia with still incompletely resolved mechanisms. The discovery of diagnostic and predictive biomarkers thus remains a major challenge. The method of the invention uses radiomics corresponding to texture features extracted from a plurality of previously-acquired medical brain images and correlated with previously-acquired clinical and/or biological data. A classifier is trained beforehand for learning these radiomics, and then operated on radiomics computed from at least one brain image of a patient to generate a score representative of its risks of neurodegenerative decline. By applying this method on a cohort of 160 MCI and non-MCI patients, the inventors show that MCI patients could be early predicted with a mean accuracy of 88%.

Abstract: The present invention relates to the field of therapeutic treatment of polycystic ovary syndrome (PCOS). Polycystic ovary syndrome, PCOS, is the most common female reproductive disorder against which no therapeutic solution is available, beyond changes in the lifestyle. The inventors have now shown by using in vivo preclinical models, that individuals affected with PCOS have an abnormal elevated production of GnRH and that this elevated production of GnRH was transmitted to their offspring that also develop PCOS. Further, by examining AMH levels in a cohort of pregnant PCOS and control women, the inventors have found that AMH concentrations are significantly higher in PCOS women as compared to healthy women during the second trimester of gestation. These unexpected findings has allowed conceiving both prevention and treatment therapeutic strategies based on the administration of GnRH antagonists.

Abstract: A method of diagnosing an MSI cancer in a patient including extracting and sequencing DNA from a tumoral sample and if available from a normal sample and operate an analyse of MNRs. The method is based on the demonstration that the FDA-approved NGS-based diagnostic test for identifying MSI in mCRC and nmCRC gave inaccurate results when compared with the gold standard reference methods. Consequently, whole exome sequencing (WES) data from all samples was further analyzed to improve detection of the MSI genomic signal in CRC and other primary tumor types. This allowed identification of weaknesses and limits of MSISensor and the design and validation of a newly optimized algorithm, namely MSICare. The high accuracy of MSICare for the detection of MSI in CRC and non-CRC tumors should allow it to become a future reference test for assessing MSI in pan-cancer.
