The heterogeneity of psychiatric disorders makes researching disorder-specific neurobiological markers an ill-posed problem. Here, we face the need for disease stratification models by presenting a generalizable multivariate normative modelling framework for characterizing brain morphology, applied to bipolar disorder (BD). We employed deep autoencoders in an anomaly detection framework, combined with a confounder removal step integrating training and external validation.

The current study, therefore, aimed to identify predictors of success related to psychological intervention in a single primary health care center in the north of Portugal.
Method: This was a retrospective study from secondary data, using the data from 1024 clients who attended the psychological consultation at a primary health care center over a period of 8 years.
Objective: Metastatic disease is common in medullary thyroid carcinoma (MTC) and it is usually detected by raising calcitonin and carcinoembryonic antigen (CEA) levels. Nuclear medicine imaging has an important role in lesion identification/characterisation. We aim to compare Ga-DOTANOC PET/CT and F-FDG PET/CT performance and to explore the correlations between tumoral markers and functional imaging.
