Crossmodal plasticity following short-term monocular deprivation.

A brief period of monocular deprivation (MD) induces short-term plasticity of the adult visual system. Whether MD elicits neural changes beyond visual processing is yet unclear. Here, we assessed the specific impact of MD on neural correlates of multisensory processes. Neural oscillations associated with visual and audio-visual processing were measured for both the deprived and the non-deprived eye. Results revealed that MD changed neural activities associated with visual and multisensory processes in an eye-specific manner. Selectively for the deprived eye, alpha synchronization was reduced within the first 150 ms of visual processing. Conversely, gamma activity was enhanced in response to audio-visual events only for the non-deprived eye within 100-300 ms after stimulus onset. The analysis of gamma responses to unisensory auditory events revealed that MD elicited a crossmodal upweight for the non-deprived eye. Distributed source modeling suggested that the right parietal cortex played a major role in neural effects induced by MD. Finally, visual and audio-visual processing alterations emerged for the induced component of the neural oscillations, indicating a prominent role of feedback connectivity. Results reveal the causal impact of MD on both unisensory (visual and auditory) and multisensory (audio-visual) processes and, their frequency-specific profiles. These findings support a model in which MD increases excitability to visual events for the deprived eye and audio-visual and auditory input for the non-deprived eye.

Distress, anxiety, depression and unmet needs in thyroid cancer survivors: a longitudinal study.

PURPOSE: Despite a good prognosis, thyroid cancer (TC) survivors often report psychological distress and decreased quality of life. This longitudinal study aims to evaluate TC survivors' levels of distress, anxiety, depression and unmet needs, checking potential life events. METHODS: Distress Thermometer, Hospital Anxiety Depression Scale, Supportive Care Need Survey (short form) and Interview for Recent Life Events were administered to 73 TC survivors (T0) and 44 of them were re-tested one year later (T1). Participants were at 0-5, 5-10 or >10 years from the end of their cancer-related treatments. RESULTS: At T0, distress, anxiety and depression mean scores were 6.4, 6.8 and 5.3, while at T1 they were 5.5, 4.8 and 5.1. Only anxiety scores decreased significantly between T0 and T1. 50.7% of patients had unmet psychological needs at T0 and 50.0% at T1. Most participants were satisfied in the communicative/ informative (T0:79.5%; T1: 77.3%) and social/health care areas (T0:74.0%; T1:75.0%). The most experienced stressful events detected concerned their working areas. CONCLUSIONS: Results confirmed that patients reported distress, anxiety and depression concerns even many years after the end of treatments. Both medical and psychological surveillance are relevant to improving TC survivors' wellbeing.
