PURPOSE:
Primary end point was to assess diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) in detecting peritoneal metastases (PM). Secondary end points were determining the diagnostic sensitivity and specificity of CT in detecting PM according to the peritoneal cancer index (PCI), investigating correlations between radiological and surgical PCI, and comparing diagnostic yield of CT versus positron emission tomography (PET)/CT.

The ability of seeing with the mind’s eye, the visual mental imagery, is peculiarly compromised in patients with representational neglect. Representational neglect affects the processing of the left side of a mental image and may selectively concern the ability to imagine places and/or objects. Right-brain damaged patients with representational neglect for places (RN+) lose the ability to imagine themselves within a familiar place and fail in transforming an egocentric representation of the environment into an allocentric one and vice-versa.

Generalized anxiety disorder (GAD) has excessive anxiety and uncontrollable worry as core symptoms. Abnormal cerebral functioning underpins the expression and perhaps pathogenesis of GAD: Studies implicate impaired communication between the amygdala and the pre-frontal cortex (PFC). Our aim was to longitudinally investigate whether such network abnormalities are spatially restricted to this circuit or if the integrity of functional brain networks is globally disrupted in GAD.

Monkey neurophysiology and human neuroimaging studies have demonstrated that passive viewing of optic flow stimuli activates a cortical network of temporal, parietal, insular, and cingulate visual motion regions. Here, we tested whether the human visual motion areas involved in processing optic flow signals simulating self-motion are also activated by active lower limb movements, and hence are likely involved in guiding human locomotion. To this aim, we used a combined approach of task-evoked activity and resting-state functional connectivity by fMRI.

Moral sense is defined as a feeling of the rightness or wrongness of an action that knowingly causes harm to people other than the agent. The large amount of data collected over the past decade allows drawing some definite conclusions about the neurobiological foundations of moral reasoning as well as a systematic investigation of methodological variables during fMRI studies. Here, we verified the existence of converging and consistent evidence in the current literature by means of a meta-analysis of fMRI studies of moral reasoning, using activation likelihood estimation meta-analysis.

Studies indicate that both explicit and implicit processing of affectively charged stimuli may be reflected in specific behavioural markers and physiological signatures. Here, we investigated whether the pleasantness ratings of a neutral target were affected by the subliminal perception of a painful (a slap) or pleasant (a caress) touch delivered to others. In particular, we combined the continuous flash suppression technique with the affective misattribution procedure to explore subliminal processing of observed pain and pleasure in others.

Recently, Poly-ADP-Ribose Polymerase (PARP) inhibitors are one of the most intensively studied group of antiblastic agents for the management of recurrent ovarian cancer. Among this family, Olaparib was the first to be approved by European Medicines Agency as maintenance therapy post-response to platinum-based chemotherapy for recurrent ovarian cancer in women with deleterious BRCA1/2 mutation. Following that, the Food and Drug Administration (FDA) approved Olaparib monotherapy as fourth or later line of treatment in advanced ovarian cancer with deleterious germ-line BRCA1/2 mutation.

PURPOSE: The aim of this study was to validate the role of MR/Ultrasound Fusion-Guided Targeted Biopsy as a first diagnostic modality in subjects with clinical suspicion of prostate cancer (PCa). MATERIALS AND METHODS: 108 men (age range 46-78 years) with clinical suspicion for PCa (PSA > 4 ng/mL) underwent multiparametric MRI of the prostate (mpMRI) and, when suspicious lesion were found (according to the PIRADSv2 scoring system), targeted biopsy was performed. All patients without significant alteration patterns at mpMRI have been referred for follow-up at 1 year.

Objectives: To evaluate accuracy and inter-observer variability using Vesical Imaging-Reporting and Data System (VI-RADS) for discrimination between non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). Methods: Between September 2017 and July 2018, 78 patients referred for suspected bladder cancer underwent multiparametric MRI of the bladder (mpMRI) prior to transurethral resection of bladder tumor (TURBT). All mpMRI were reviewed by two radiologists, who scored each lesion according to VI-RADS.

A Brain–Computer Interface (BCI) uses measurements of the voluntary brain activity for driving a communication system; it requires the activation of mental tasks. In the last few years, a new paradigm of activation has been used, consisting in the autonomous brain activation through self-induced emotions, remembered on autobiographical basis. In the present paper, such paradigm is implemented and the resulting BCI system is described, from the classification strategy to the graphic user interface necessary for synchronising mental tasks and collecting EEG signals derived by emotions.
