Background: Severe socio-emotional impairments characterize the behavioral variant of frontotemporal dementia (bvFTD). However, literature reports social cognition disorders in other dementias. Objective: In this study, we investigated the accuracy of social cognition performances in the early and differential diagnosis of bvFTD. Methods: We included 131 subjects: 32 bvFTD, 26 Alzheimer’s disease (AD), 16 primary progressive aphasia (PPA), 17 corticobasal syndrome (CBS), and 40 healthy control (HC). Each subject completed the Ekman 60 faces (Ek-60F) test assessing basic emotion recognition and the Story-based Empathy Task (SET) assessing attribution of intentions/emotions. A combined social measure (i.e., Emotion Recognition and Attribution (ERA) index) was calculated. One-way ANOVA has been used to compare performances among groups, while receiver operating characteristic (ROC) curve tested measures ability to distinguish subjects with and without bvFTD. Results: Ek-60F and ERA index scores were significantly lower in bvFTD versus HC, AD, and PPA groups. ROC analyses significantly distinguished bvFTD from HC (AUC 0.82–0.92), with the Ek-60F test showing the highest performance, followed by the ERA index. These two social measures showed the best accuracy in detecting bvFTD from AD (AUC 0.78–0.74) and PPA (AUC 0.80–0.76). Investigated measures failed in detecting bvFTD from CBS. Conclusion: Accuracy analyses support the advantage of using social cognition tests for bvFTD diagnosis. Short social battery may reduce uncertainties and improve disease identification in clinical settings. We recommend a revision of current clinical criteria considering neuropsychological deficits in emotion recognition and processing tasks as key cognitive markers of this neurodegenerative syndrome.

The use of social tasks in the neuropsychological assessment of the behavioral variant of frontotemporal dementia (bvFTD) is at present not required by diagnostic guidelines, despite extensive literature shows relevant social cognitive dysfunctions in such patients. In this systematic review, we explored the clinical maturity of social cognition measures in the diagnosis of bvFTD. Papers were selected according to the PRISMA guidelines by searching the PubMed and Medline databases. Only papers reporting indices of diagnostic accuracy and/or sensitivity/specificity in classifying bvFTD from controls or from other relevant diseases were considered. Quality of evidence was assessed through QUADAS-2. Among the 663 articles entered in the paper selection only 14 papers were eligible for the scope of the present review and showed an overall moderate-to-low quality. The major risk of bias was the lack of pathological confirmation. The evaluation of the accuracy of social cognition tasks in bvFTD detection compared to normal controls, as well as in the discrimination with Alzheimer's disease and psychiatric patients, is mainly focused on emotion recognition and theory of mind. However, the use of different cognitive measures, variable task formats and the limited normative data hamper study comparability. Although literature seems to suggest that emotion recognition and ToM tasks could be the best choice to ensure a high diagnostic accuracy in clinical settings, further comparative studies are required and no recommendation concerning the use of a specific social task in bvFTD diagnosis can be currently provided.

Psychosocial variables are key factors influencing the delicate equilibrium of chronic patients during crisis time. In this study, we explored distress, anxiety, depression, loneliness, coping strategies, and changes in life habits in 43 beta-thalassemia patients and 86 controls during Covid-19 pandemic. Patients showed higher anxiety levels and a predominant transcendent coping profile compared to controls. Patients significantly differed from controls in outdoor habits. Social isolation and habits changes in uncertain life-threaten situations as Covid-19 pandemic are particularly detrimental in fragile beta-thalassemia patients. Structured support interventions are needed to promote well-being in the Covid-19 era.

Background Psychosocial variables are key factors influencing psycho-physical equilibrium in migraine patients. Social isolation and vulnerability to stressors may prevent efficient psychological adjustment negatively affecting adaptation to life changes, as that imposed during Covid-19 lockdown. Here, we explored psychosocial dimensions and changes in clinical condition during Covid-19 lockdown in migraine patients, with regard to migraine type and headache impact. Methods Sixty-four migraine patients (32 episodic and 32 chronic) and 64 healthy control subjects were included in a case-control cross-sectional study. A two-step clustering procedure split patients into two clusters, based on the Headache Impact Test. Perceived global distress, loneliness, empathy, and coping levels were compared in groups, as well as changes in clinical condition. Results Migraine patients reported higher general loneliness and lower social support compared to healthy control subjects. Emotional loneliness was more marked in patients with higher headache impact. This subgroup of patients more frequently reported changes in the therapeutic and care paths as the perceived cause of the occurrence of motor or extra-motor symptomatology. Conclusions Migraine patients, especially those more severely affected, proved more vulnerable than healthy control subjects to Covid-19 lockdown. Long-lasting interruption of social interactions may be detrimental in fragile patients that are in need of structured support interventions to maintain psycho-physical wellbeing.

Objective:Late-onset amnestic mild cognitive impairment (aMCI) with long disease course and slow progression has been recently recognized as a possible phenotypical expression of a limbic-predominant neurodegenerative disorder. Basic emotion recognition ability crucially depending on temporo-limbic integrity is supposed to be impaired in this group of MCI subjects presenting a selective vulnerability of medio-temporal and limbic regions. However, no study specifically investigated this issue.Methods:Hereby, we enrolled 30 aMCI with a biomarker-based diagnosis of Alzheimer’s disease (i.e., aMCI-AD, n = 16) or a biomarker evidence of selective medio-temporal and limbic degeneration (aMCI-mTLD, n = 14). Ekman-60 Faces Test (Ek-60F) was administered to each subject, comparing the performance with that of 20 healthy controls (HCs).Results:aMCI-mTLD subjects showed significantly lower Ek-60F global scores compared to HC (p = 0.001), whose performance was comparable to aMCI-AD. Fear (p = 0.02), surprise (p = 0.005), and anger (p = 0.01) recognition deficits characterized the aMCI-mTLD performance. Fear recognition scores were significantly lower in aMCI-mTLD compared to aMCI-AD (p = 0.04), while no differences were found in other emotions.Conclusions:Impaired social cognition, suggested by defective performance in emotion recognition tasks, may be a useful cognitive marker to detect limbic-predominant aMCI subjects among the heterogeneous aMCI population.

First-person experience of stressful life events can change individuals' risk attitudes, driving to increased or decreased risk perception. This shift to more risk-averse or risk-loving behaviors may find a correlate in the individual psycho-socio-emotional profile. To this purpose, we aimed to estimate the relationship between differences in risk-taking attitudes toward possible negative health outcomes and psycho-socio-emotional dimensions modulating the experience of life-threatening situations, in the context of the Covid-19 pandemic. In March 2020, we launched the PsyCovid Study (https://wprn.org/item/428452) to assess psycho-socio-emotional changes due to Covid-19 pandemic in the Italian population. Additionally, we distributed to 130 participants the Covid-19 Risk Task, including monetary and health-related stimuli, estimating a measure of risk-aversion toward health and classifying participants on the basis of their risk-attitude profiles. The set of psycho-socio-emotional variables was reduced to three PCA components: Proactivity, Isolation, Inactivity. The individual degree of risk-aversion toward negative health outcomes was directly related to Proactivity, encasing empathic, social support and positive coping strategies, which may prompt individuals to put in place self-protection strategies toward possible negative health consequences. These findings indicate that a risk-averse profile toward possible negative health outcomes may be associated to higher levels of individual prosocial and proactive dispositions, possibly making individuals' more compliant with the social and hygienic guidelines and, thus, reducing their exposure to the SARS-CoV-2 infection.

Covid-19 pandemic is exerting a tragic impact all around the world. First-person experience of life-threatening and stressful events can modify individuals’ risk perception, and, consequently, risk-taking behaviours. Here we investigated risk-taking profiles in 130 Italian residents, and compared healthcare to non-healthcare workers, during the lockdown phase. We ad hoc developed the “Covid-19 Risk Task”, including the classic monetary Holt-Laury Paired Lottery Task (Monetary Condition, MC) and two new ecological conditions exploring Covid-19 related risk-taking aptitudes in relation to different health (Health Status Condition, HsC) and employment (Employment Status Condition, EsC) outcomes. Results showed that, in the whole sample, individuals were more risk-averse in MC than in HsC and EsC. Moreover, a payoff increase produced a shift toward more risk-averse behaviours in MC, but not in HsC and EsC, where we found an opposite trend suggesting a more risk-loving behaviour. Finally, we found that healthcare workers were significantly less risk-averse compared to non-healthcare workers in EsC, but not in MC and HsC. These findings provided evidence of the possible effects of Covid-19 outbreak on risk-taking aptitudes. The negative impact on human choices and, consequently, on the whole world economy of this catastrophic life event must not be underestimated.

The early identification of fragile populations in the Covid-19 era would help governments to allocate resources and plan strategies to contain consequences of the pandemic. Beyond frailty, social vulnerability to environmental stressors, such as the social distancing enforced to reduce the SARS-CoV2 contagion, can modify long-term disease risk and induce health status changes in the general population. We assessed frailty and social vulnerability indices in 1,258 Italian residents during the first lockdown phase via an on-line survey. We compared indices taking into account age categories and gender. While frailty showed a linear increase with age and was greater in females than in males, social vulnerability was higher in young adults and elders compared to middle aged and older adults, and in males than females. Both frailty and social vulnerability contributed in explaining the individual perception of the impact of Covid-19 emergency on health, which was further influenced by proactive attitudes/behaviors and social isolation. Social isolation and loneliness following the Covid-19 outbreak may exert dramatic psychosocial effects in the general population. The early detection of vulnerable categories, at risk to become ill and develop long-lasting health status changes, would help to prevent consequences on general well-being by allocating resources to targeted interventions managing psychosocial distress and increasing young adults and elderly resilience toward the post-Covid-19 crisis.

Corylus avellana L. is known for its healthy properties, and yet previous studies have not dealt with its effects on human innate response. The aim of this study is to assess if C. avellana has an immune adjuvant effect. Human macrophages were pre-treated with hazelnut liquid extract, found to be rich in phenylpropanoids, and subsequently infected with Staphylococcus aureus. Based on the intracellular bacteria CFU reduction and on the treatment doses used, the donors were divided into High-Dose and Low-Dose-Responders. Expression profile for inflammatory and Iron metabolism genes, both for Peripheral Blood Mononuclear Cells and Macrophages, highlighted that Low-Dose-Responders came from a more pronounced pro-inflammatory milieu as compared with High-Dose-Responders. Blood test results revealed that Low-Dose-Responders had higher LDL C and Triglycerides and lower HDL C. Overall, our results suggest that the effect of the extract on Macrophage immune response is influenced by the intracellular inflammatory status of the donor. © 2018 Elsevier Ltd

Life sciences such as medical, nutritional, and those related to agrarian biotechnologies are experiencing a constant increase. Therefore, food consumption is today related to health state. Aiming to create an innovative spinneret system that defines the tight correlation between high nutritional and nutraceutical value of foods and their beneficial effects on consumer’s health state, we tested the effects related to the administration of 40 g of the Tonda Gentile Romana Italian hazelnut cultivar (Viterbo, Italy). To this end, we enrolled 24 subjects for a period of 14 weeks, based on a crossover design. Although several papers and reviews on hazelnut intake benefits are available, few studies have investigated the effects of hazelnut-enriched diet on plasma key parameters commonly used to ascertain the individual’s well-being status. The primary endpoint of the trial was to assess LDL change related to hazelnut administration, which resulted in significant beneficial effects on cholesterol parameters (LDL dropped from 133.09 mg/dl to 119.18 mg/dl). Interestingly, despite within the normal ranges, uric acid and serum creatinine mean values significantly decreased after hazelnut intake. A significant increment was also observed for ALT (from 30.9 U/L to 35.22 U/L, P = 0.01), while GGT significantly decreased from 38.04 mg/dl at T0 to 35.27 mg/dl at T1 (P = 0.001). No significant changes were also observed in azotemia, serum iron, glycemia, AST, total bilirubin, Hb, WBCs, RBCs, platelet count, and total plasma proteins. All the blood parameters analyzed appeared to be reversible after 6 weeks from the end of the treatment. Mann-Whitney U test did not show any significant differences in T0 - T1 Δ% LDL considering gender, age and baseline LDL. These findings may be of help in the development of strategies for personalized nutrition and diseases management.
