Acute effects of interferon-alpha on cellular anabolic and catabolic processes are associated with the development of fatigue during Interferon-alpha-based therapy for Hepatitis-C: A preliminary study.

Introduction: Interferon-alpha (IFN-α) is a key mediator of antiviral immune responses used to treat Hepatitis-C virus (HCV) infection. Though clinically effective, IFN-α frequently induces functionally impairing mood and motivation symptoms, particularly fatigue. Unlike mood impairment, which typically emerges after weeks of treatment, fatigue tends to emerge and evolve rapidly, typically within hours of the first IFN-α injection.

Developmental trajectories of metacognitive processing and executive function from childhood to older age.

The modern understanding of the term metacognition encompasses two levels of processing: a lower level or of one's own thoughts and a higher level or of our thinking. Metacognition, therefore, bears conceptual similarity with executive function: both are concerned with top-down monitoring and control of cognition in the service of ongoing goal-directed behaviour. Previous studies have shown a possible executive function advantage in multilingual speakers but also a possible disadvantage in metacognitive processing.

A role for the cerebellum in the control of verbal interference: Comparison of bilingual and monolingual adults.

We evaluate brain structure sensitivity to verbal interference in a sentence interpretation task, building on previously reported evidence that those with better control of verbal interference show higher grey matter density in the posterior paravermis of the right cerebellum. We compare brain structure sensitivity to verbal interference control across two groups, English monolingual (N = 41) and multilingual (N = 46) adults. Using voxel-based morphometry, our primary goal was to identify and explore differences in regional patterns of grey matter sensitivity to performance on the sentence interpretation task, controlling for group variability in age, nonverbal reasoning and vocabulary knowledge.

Developmental trajectories of control of verbal and non-verbal interference in speech comprehension in monolingual and multilingual children.

Research on speech comprehension in noise indicates that a multilinguistic experience may confer advantages in filtering out verbal interference, an effect observed both in children acquiring two or more languages since birth (Filippi, Morris, Richardson, et al., 2015) and in second language learner adults (Filippi, Leech, Thomas, et al., 2012).

The Importance of Socioeconomic Status as a Modulator of the Bilingual Advantage in Cognitive Ability.

Between-group variability in socioeconomic status (SES) has been identified as a potentially important contributory factor in studies reporting cognitive advantages in bilinguals over monolinguals (the so called "bilingual advantage"). The present study addresses the potential importance of this alternative explanatory variable in a study of low and high SES bilingual and monolingual performance on the Simon task and the Tower of London (TOL) task. Results indicated an overall bilingual response time advantage on the Simon task, despite equivalent error rates.

Evidence against a cognitive advantage in the older bilingual population.

Recent evidence has challenged long-standing claims that multi-language acquisition confers long-term advantages in executive function and may protect against age-related cognitive deterioration. We assessed evidence for a bilingual advantage in older monolingual and bilingual residents matched on age, gender, and socioeconomic status. A comprehensive battery of tests was administered to measure non-verbal reasoning, working memory capacity, visuo-spatial memory, response inhibition, problem solving, and language proficiency.

Mortality Risk in Alcoholic Patients in Northern Italy: Comorbidity and Treatment Retention Effects in a 30-Year Follow-Up Study.

Aims: To analyse the general and cause-specific mortality over the course of 30 years among subjects treated for alcohol use disorders (AUD) in Northern Italy.

Methods: Cohort of 2499 subjects followed-up for mortality until 31 December 2012. Standardized mortality ratios (SMRs) and 95% confidence intervals (CI) were computed to compare the mortality in the cohort with the general population.
