Type 2 Diabetes Mellitus in Youth Exposed to Antipsychotics: A Systematic Review and Meta-analysis
Britta Galling,Alexandra Roldán,René Ernst Nielsen,Jimmi Nielsen,Tobias Gerhard,Maren Carbon,Brendon Stubbs,Brendon Stubbs,Davy Vancampfort,Marc De Hert,Mark Olfson,Kai G. Kahl,Andrés Martin,Jeff J. Guo,Hsien-Yuan Lane,Fung-Chang Sung,Chun-Hui Liao,Celso Arango,Christoph U. Correll,Christoph U. Correll,Christoph U. Correll +20 more
TL;DR: Although T2DM seems rare in antipsychotic-exposed youth, cumulative risk and exposure-adjusted incidences and IRRs were significantly higher than in healthy controls and psychiatric controls.
Journal ArticleDOI
Antipsychotic augmentation vs. monotherapy in schizophrenia: systematic review, meta-analysis and meta-regression analysis.
Britta Galling,Alexandra Roldán,Katsuhiko Hagi,Liz Rietschel,Frozan Walyzada,Wei Zheng,Xiao-Lan Cao,Yu-Tao Xiang,Mathias Zink,John M. Kane,Jimmi Nielsen,Stefan Leucht,Christoph U. Correll +12 more
TL;DR: The data suggest that the common practice of antipsychotic augmentation in schizophrenia lacks double‐blind/high‐quality evidence for efficacy, except for negative symptom reduction with aripiprazole augmentation.
Journal ArticleDOI
Resting-state functional connectivity alterations in the default network of schizophrenia patients with persistent auditory verbal hallucinations
Anna Alonso-Solís,Yolanda Vives-Gilabert,Eva Grasa,Maria J. Portella,Mireia Rabella,Rosa Blanca Sauras,Alexandra Roldán,Fidel Núñez-Marín,Beatriz Gómez-Ansón,Victor L. Perez,Enric Álvarez,Iluminada Corripio +11 more
TL;DR: The results suggest cross-network abnormalities between DN and salience system in patients with persistent hallucinations in the default mode network.
Journal ArticleDOI
Deep brain stimulation in treatment resistant schizophrenia: A pilot randomized cross-over clinical trial.
Iluminada Corripio,Alexandra Roldán,Salvador Sarró,Peter J. McKenna,Anna Alonso-Solís,Mireia Rabella,Anna Díaz,Dolors Puigdemont,Víctor Pérez-Sola,Enric Álvarez,Antonio Arévalo,Pedro Pablo Padilla,Jesus Ruiz-Idiago,Rodrigo Rodríguez,Joan Molet,Edith Pomarol-Clotet,Maria J. Portella +16 more
TL;DR: These preliminary findings point to the possibility of DBS having therapeutic effects in patients with schizophrenia who do not respond to any other treatment, and to the extent of the benefits and whether these can be achieved without psychiatric side-effects.
Journal ArticleDOI
Altered amplitude of low frequency fluctuations in schizophrenia patients with persistent auditory verbal hallucinations
Anna Alonso-Solís,Yolanda Vives-Gilabert,Maria J. Portella,Mireia Rabella,Eva Grasa,Alexandra Roldán,Alejandro Keymer-Gausset,C. Molins,Fidel Núñez-Marín,Beatriz Gómez-Ansón,Enric Álvarez,Iluminada Corripio +11 more
TL;DR: The results suggest that altered dynamics in low-frequency fluctuations may play a key role in the neurophysiology of auditory hallucinations.
