Striatal dopamine D2-like receptors availability in obesity and its modulation ...
Ribeiro, Gabriela; Maia, Ana; Cotovio, Gonçalo; Oliveira, Francisco P.M.; Costa, Durval C.; Oliveira-Maia, AJOK; There is significant evidence linking a 'reward deficiency syndrome' (RDS), comprising decreased availability of striatal dopamine D2-like receptors (DD2lR) and addiction-like behaviors underlying substance use disorders and obesity. Regarding obesity, a systematic review of the literature with a meta-analysis of such data is lacking. Following a systematic review of the literature, we performed random-effe...

METHODS: A multicenter longitudinal cohort study was conducted in patients scheduled for bariatric surgery (surgical group), assessed at baseline and 2 f...

Hypomania symptoms across psychiatric disorders
Camacho, Marta; Almeida, Sílvia; Moura, Ana Rita; Fernandes, Ana B.; Ribeiro, Gabriela; Da Silva, Joaquim Alves; Barahona-Corrêa, J. BernardoIntroduction: Hypomania symptoms are best described as a continuum, ranging beyond Bipolar Spectrum Disorders (BSD). Other nosological entities, such as major depressive disorder, schizoaffective disorder, or borderline personality disorder, may also share symptoms with BSD, raising challenges for differential diagnosis. While the Hypomania Checklist-32 is one of the most widely used tools for screening hypoman...
Association between hedonic hunger and body-mass index versus obesity status
Ribeiro, Gabriela; Camacho, Marta; Santos, Osvaldo; Pontes, Cristina; Torres, Sandra; Oliveira-Maia, AJObesity-associated differences in hedonic hunger, while consistently reported, have not been adequately quantified, with most studies failing to demonstrate strong correlations between Body Mass Index (BMI) and hedonic hunger indicators. Here, we quantified and assessed the nature of the relationship between hedonic hunger and BMI, in a cross-sectional study using the Portuguese version of the PFS (P-PFS) to me...
