The Italian validation of the Communicative Effectiveness Index Questionnaire: a multicentric study.

INTRODUCTION: Common assessment tools for aphasia evaluate single language impairments but not their functional impact on patient's communication skills in daily life. The lack of tools focused on ecological aspects might affect the choice of rehabilitative trainings. The Communicative Effectiveness Index (CETI) represents an attempt to assess the communicative abilities in "ecologic" context. This study aimed to explore psychometrics properties of the Italian translation and adaptation of CETI (I-CETI). METHODS: Sixty-eight patients with aphasia due to left hemispheric stroke admitted to post-acute rehabilitation units and their relatives were included in the study. Data were collected in three different sessions. At study entry, patients were assessed for language, depression, and functional abilities, while their caregivers and speech therapists independently completed the I-CETI to assess inter-rater agreement (baseline). One week later, caregivers and speech therapists completed again I-CETI, to assess test-retest reliability (T1). Last, at discharge, patients completed again the evaluation protocol, and caregivers and speech therapists completed I-CETI (T2). RESULTS: I-CETI showed high internal validity, excellent reliability, and good correlation between scores obtained by speech therapists and caregivers. Moreover, scores of I-CETI had quite good correlations with a traditional tool to assess language, and with measures of functional independence both at study entry and at discharge. DISCUSSION: I-CETI showed good psychometric proprieties. These results allowed considering I-CETI as a reliable tool to assess effects of speech treatments on the communicative abilities in patients with aphasia. Furthermore, I-CETI might help clinicians to develop treatments more tailored on the "ecologic" difficulties of patients.

Differential impact of government lockdown policies on reducing air pollution levels and related mortality in Europe.

Previous studies have reported a decrease in air pollution levels following the enforcement of lockdown measures during the first wave of the COVID-19 pandemic. However, these investigations were mostly based on simple pre-post comparisons using past years as a reference and did not assess the role of different policy interventions. This study contributes to knowledge by quantifying the association between specific lockdown measures and the decrease in NO2, O3, PM2.5, and PM10 levels across 47 European cities. It also estimated the number of avoided deaths during the period. This paper used new modelled data from the Copernicus Atmosphere Monitoring Service (CAMS) to define business-as-usual and lockdown scenarios of daily air pollution trends. This study applies a spatio-temporal Bayesian non-linear mixed effect model to quantify the changes in pollutant concentrations associated with the stringency indices of individual policy measures. The results indicated non-linear associations with a stronger decrease in NO2 compared to PM2.5 and PM10 concentrations at very strict policy levels. Differences across interventions were also identified, specifically the strong effects of actions linked to school/workplace closure, limitations on gatherings, and stay-at-home requirements. Finally, the observed decrease in pollution potentially resulted in hundreds of avoided deaths across Europe.

Nature and nurture effects on the spatiality of the mental time line.

The nature-nurture debate regarding the origin of mental lines is fundamental for cognitive neuroscience. We examined natural-nurture effects on the mental time line, applying three different challenges to the directionality of time representation. We tested (1) patients with left-neglect and healthy participants, who are (2) left-to-right or right-to-left readers/writers, using (3) a lateralized left-right button press or a vocal mode in response to a mental time task, which asks participants to judge whether events have already happened in the past or are still to happen in the future. Using lateralized responses, a spatial-temporal association of response code (STEARC) effect was found, in concordance with the cultural effects. With vocal responses (no lateralization), past and future events showed similar results in both cultures. In patients with neglect, who have a deficit of spatial attention in processing the left side of space, future events were processed more slowly and less accurately than past events in both cultures. Our results indicate the existence of a "natural" disposition to map past and future events along a horizontal mental time line, which is affected by the different ways in which spatial representation of time is introduced.
