A meta-analysis of cognitive performance in melancholic versus non-melancholic unipolar depression
2016
Abstract Background Recently there is increasing recognition of cognitive dysfunction as a core feature of Major Depressive Disorder (MDD). The goal of the current meta-analysis was to review and examine in detail the specific features of cognitive dysfunction in Melancholic (MEL) versus Non-Melancholic (NMEL) MDD. Methods An electronic literature search was performed to find studies comparing cognitive performance in MEL versus NMEL. A meta-analysis of broad cognitive domains ( processing speed , reasoning/problem solving , verbal learning , visual learning , attention/working memory ) was conducted on all included studies (n=9). Sensitivity and meta-regression analyses were also conducted…
Where There is Smoke There is Fear-Impaired Contextual Inhibition of Conditioned Fear in Smokers
2016
The odds-ratio of smoking is elevated in populations with neuropsychiatric diseases, in particular in the highly prevalent diagnoses of post-traumatic stress and anxiety disorders. Yet, the association between smoking and a key dimensional phenotype of these disorders—maladaptive deficits in fear learning and fear inhibition—is unclear. We therefore investigated acquisition and memory of fear and fear inhibition in healthy smoking and non-smoking participants (N=349, 22% smokers). We employed a well validated paradigm of context-dependent fear and safety learning (day 1) including a memory retrieval on day 2. During fear learning, a geometrical shape was associated with an aversive electric…
Anxiety and depression among adult amputees: the role of attachment insecurity, coping strategies and social support.
2018
A number of studies have investigated the role of coping and social support as protective factors for psychosocial adjustment after amputation. In contrast, few have focused on the role of attachment styles. Therefore, the purpose of this study was to examine the relationship between attachment insecurity, social support, coping strategies and negative emotions, such as anxiety and depression, in adult amputees. Sixty-two amputated adults (71% males, 29% females), recruited from the Prosthetic Centre of the Italian Workers’ Compensation Authority, completed the Attachment Style Questionnaire, the Coping Inventory for Stressful Situations, the Multidimensional Scale of Perceived Social Suppo…
The effects of post-awakening light exposure on the cortisol awakening response in healthy male individuals.
2019
Abstract Background It is assumed that the expression of the cortisol awakening response (CAR) is modulated by light exposure during the peri-awakening period. While initial evidence supports this principal effect, the specific role of the spectral composition of light (brightness and wavelength) is still incompletely understood. Method Two counterbalanced within-subject experiments were conducted in a standardized sleep laboratory setting to investigate the effect of light intensity (study I; two days: dim vs. bright light) and spectral composition (study II; three days: red vs. blue vs. green light) on the CAR. Across studies, light exposure was conducted for one-hour post-awakening and t…
Long-term cost-effectiveness of cognitive behavioral therapy versus psychodynamic therapy in social anxiety disorder.
2015
Background To determine the cost-effectiveness of cognitive behavioral therapy (CBT) versus psychodynamic therapy (PDT) in the treatment of social anxiety disorder after a follow-up of 30 months from a societal perspective. Methods This analysis was conducted alongside the multicenter SOPHO-NET trial; adults with a primary diagnosis of social anxiety disorder received CBT (n = 209) or PDT (n = 207). Data on health care utilization and productivity loss were collected at baseline, after 6 months (posttreatment), and three further follow-ups to calculate direct and indirect costs. Anxiety-free days (AFDs) calculated based on remission and response were used as measure of effect. The increment…

Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.
2017
Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…

Domain-specific associations between disability and depression, anxiety, and somatization in primary care patients
2018
Abstract This study explores the associations between different disability domains and the most prevalent symptoms of mental disorders in primary care patients (i.e. depression, anxiety, and somatization). A total of 1241 participants from 28 primary care centres completed self-report measures of depression, anxiety, and somatization. This same sample also completed the Sheehan Disability Scale (SDS) to assess functional impairment in work, social life, and family life domains. Associations between the symptoms and each disability domain were examined using hierarchical regression analyses. Depression emerged as the strongest predictor of all three disability domains. Somatization was assoc…
