In patients infected by SARS‐CoV‐2 who experience an exaggerated inflammation leading to pneumonia, monocytes likely play a major role but have received poor attention. Thus, we analyzed peripheral blood monocytes from patients with COVID‐19 pneumonia and found that these cells show signs of altered bioenergetics and mitochondrial dysfunction, had a reduced basal and maximal respiration, reduced spare respiratory capacity, and decreased proton leak. Basal extracellular acidification rate was also diminished, suggesting reduced capability to perform aerobic glycolysis. Although COVID‐19 monocytes had a reduced ability to perform oxidative burst, they were still capable of producing TNF and IFN‐γ in vitro. A significantly high amount of monocytes had depolarized mitochondria and abnormal mitochondrial ultrastructure. A redistribution of monocyte subsets, with a significant expansion of intermediate/pro‐inflammatory cells, and high amounts of immature monocytes were found, along with a concomitant compression of classical monocytes, and an increased expression of inhibitory checkpoints like PD‐1/PD‐L1. High plasma levels of several inflammatory cytokines and chemokines, including GM‐CSF, IL‐18, CCL2, CXCL10, and osteopontin, finally confirm the importance of monocytes in COVID‐19 immunopathogenesis., Investigation of patients with COVID‐19 pneumonia revealed that SARS‐CoV‐2 infection affects innate immunity by reshaping peripheral blood monocyte subsets and altering their functionality, in terms of bioenergetics, membrane potential and expression of checkpoint inhibitors.

Solitary metastasis of malignant melanoma (MM) to the gallbladder (GB) is rare and generally originates from skin melanoma. MM is a neoplasm with an often unpredictable course and metastases can potentially affecting all organs. The occurrence of metastasis in the GB is unusual and has only been exceptionally reported in the literature. We describe a case of an 86-year-old man with an isolated MM metastasis located within the GB presenting with symptoms mimicking acute cholecystitis. Anamnestically, he presented a history of malignant melanoma (Clark level III) resected from his left leg 17 years ago. Furthermore we provide a review of the literature with a focus on diagnostic clues to distinguish between primary versus secondary GB MMs and on the best surgical management that should be used.

Objective: The transition to college is considered as a risk period for the development of behavioral symptoms of eating disorders (BSEDs) and some evidence suggests that, amongst men, these symptoms occurring on a regular basis remain relatively stable over the college period. Nevertheless, little is known about factors associated with persistent engagement in and initiation of recurrent (or regular) binge eating and inappropriate weight compensatory behaviors in this population. The objective of this report was to address these research gaps. Method: Data were examined from 2,555 male first-year college students who completed an assessment of potential vulnerability factors and BSEDs at the beginning of the autumn semester (baseline) and nine months later (end of the spring semester; follow-up). Results: Elevated negative affectivity, body dissatisfaction, self-objectification, and lower self-esteem at baseline were predictive of persistent engagement in regular binge eating and four compensatory behaviors (self-induced vomiting, laxative/diuretic abuse, fasting, exercise) at follow-up, as well as initiation of all these behaviors occurring regularly (i.e., at least weekly for 3 months). Self-objectification (thinking and monitoring the body's outward appearance from a third-person perspective) emerged as the largest contributor of both the initiation and persistence of all behavioral symptoms. Discussion: Data emphasize that the same psychological factors underlie initiation and persistence of recurrent BSEDs and should shape the focus of future interventions for college men. © 2016 Wiley Periodicals, Inc.

Unilateral Spatial Neglect (USN) is normally assessed with paper-and-pencil tests. Virtual reality can be an effective neuropsychological tool for a more ecological and functional assessment and rehabilitation of neglect. We developed a 3D Virtual Reality platform - NeuroVirtual 3D - for the assessment and rehabilitation of cognitive deficits, in particular for USN. Within the virtual environments it is possible to interact with virtual objects and execute specific exercises using a Microsoft Kinect. Through the analysis of different grasping tasks it is possible to evaluate in an ecological way the patients' ability to find and handle objects in both sides of the virtual space.

This study aimed to evaluate the reliability and validity of the Neuro- Virtual Reality as tool for the neuropsychological assessment in OCD patients. We used the neuropsychological battery and a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software, in order to evaluate the executive functions, the ability to plan ahead on complex problem solving tasks in daily life in 30 obsessive compulsive disorder (OCD) patients and 30 healthy controls. The results showed the presence of difficulties of OCD patients: lower levels of divided attention and higher levels of errors; higher mean rank of inefficiencies, interpretation failures and rule breaks and longer time of execution of the whole task. By contrast, controls have higher level of efficiency and better performance. In addition, a significant correlation was found between the V-MET and the neuropsychological battery which confirms and supports the ecological validity of neurocognitive assessment through NeuroVirtual Reality.

To report on clinical outcomes of patients with early-stage glottic cancer treated with exclusive radiotherapy with specific analysis of voice quality.A consecutive cohort of 55 patients with early glottic cancer was retrospectively analyzed. Patients were treated with exclusive radiation up to a conventionally fractionated total dose of 66-70 Gy with a 3-dimensional conformal technique. Oncological outcomes and toxicity profiles were investigated. A sub-sample of this cohort was also analyzed in terms of voice quality employing subjective and objective tools such as the Voice Handicap Index-10 (VHI-10) and the Multidimensional Voice Program (MDVP™) software and was compared to a group of similar patients treated with CO2 laser cordectomy.after a median observation time of 74.5 months, 5- and 10-year local control was 89% [95% confidence interval (CI)=70.7-93.1%] and 86% (95% CI=68.7-89.6%), respectively. Larynx-preservation rate was 91.8% (95% CI=82.4%-94.9%) at 10 years. Five- and 10-year actuarial overall survival was 72% (95% CI=50.4-79.2%) and 56% (95% CI=48.7-64.3%). Maximum detected acute toxicity included G3 dermatitis (5.4%) and G4 dyspnea (1.8%). Late toxicity profile was mild. VHI-10 scores showed a mild voice disability in both groups, with no statistically significant difference (p=0.12), even when investigating different domains. Patients treated with radiation had a lower deterioration rate in all parameters excluding low voice, interruptions of sound and diplophony.Exclusive radiation proved an effective treatment for patients with early glottic cancer in terms of both oncological outcome and voice quality.

This study aimed at measuring objectively the experience of using social network sites (SNSs). At this aim, a model of experience has been defined, focusing on three main aspects of time-space continuum of individuals' states: physiological arousal, emotional valence, and attentional resources. At this purpose we developed a new approach to assess such an experience. The main idea is to consider arousal, valence and attention to track the users' experience collecting psychophysiological indexes at predefined period (for example each 10 seconds) to build an empirical model based on these data. Once we got the empirical curve we can fit these data using mathematical models.

In this paper, the Italian Society of Cardiac Rehabilitation and Prevention (GICR) presents the third survey on the status of cardiac rehabilitation (CR) in Italy. The Italian SurveY on carDiac rEhabilitation 2008 (ISYDE 2008) is a multicenter, observational study aimed at identifying the number and characteristics of Italian CR facilities, both in terms of health operators and interventions. Clinical records of all patients consecutively discharged within the whole network--composed of up to 200 CR units--from January 28 to February 10, 2008 will also be reviewed for diagnosis of admission, comorbidities, rehabilitation programs, and drug therapy, in order to obtain a snapshot of current implementation strategies in daily clinical practice. The survey will adopt a web-based methodology for data provision and transmission. Preliminary results of the survey are expected in the late summer 2008.

At CT 2007, we presented NeuroVR (http://www.neurovr.org), a free virtual reality platform based on open-source software. The software allows non-expert users to adapt the content of 14 pre-designed virtual environments to the specific needs of the clinical or experimental setting. Following the feedbacks of the 700 users who downloaded the first version, we developed a new version - NeuroVR 1.5 - that improves the possibility for the therapist to enhance the patient's feeling of familiarity and intimacy with the virtual scene, by using external sounds, photos or videos. The key characteristics that make NeuroVR suitable for most clinical applications are the high level of control of the interaction with the tool, and the enriched experience provided to the patient. Actually, NeuroVR is used in the assessment and treatment of Obesity, Alcohol Abuse, Anxiety Disorders, Generalized Anxiety Disorders, and Cognitive Rehabilitation.

Although literature does not provide a unique explanation, the importance of hippocampus for human topographical learning and orientation is assumed to be relevant by most of the authors. There is considerable evidence that the hippocampus is necessary for acquiring cognitive maps of allocentric space, which includes topographical knowledge of large-scale real environments. This study aimed to investigate neuropsychological and behavioral characteristics of topographical disorientation in a 71 years old patient, affected by an ischemic bilateral occipital lesion involving the hippocampus. Several assessment methods have been involved: neuropsychological test, paper and pencil test for the evaluation of topographical abilities, and a Virtual Reality tool. Experimental evidences for the value of an integrated evaluation approach in underlying spatial orientation difficulties are provided.

We studied 23 Parkinson's disease (PD) non-demented patients and 15 controls in Virtual Reality (VR) environments reproducing usual daily living situations. In VR sessions, PD patients performed their actions worse than controls, in terms of time of execution in exploration and pointing, precision as objects avoiding, and in semantic incidental memory task. We observed clear differences of performances between on and off status medication, with a global worsening during off phase. Moreover, all six patients with motor fluctuations described visual hallucinations during off state, with occurrence of images not included in the virtual environment.

The aim of this study was to evaluate the accuracy of contrast-enhanced colour-Doppler ultrasound (CDUS) in the diagnosis of gastro-oesophageal reflux in children.One hundred and twenty children (68 boys and 52 girls aged between 1 month and two years) with a clinical suspicion of gastro-oesophageal reflux (postprandial vomiting, weight loss, failure to thrive, anaemia, night-time coughing and crying, regurgitation, etc.) were studied by contrast-enhanced CDUS and subsequently by 24-hour pH-metry. Results of the two techniques were compared using the McNemar test.Gastro-oesophageal reflux was detected on CDUS in 84 patients and with 24-h pH-metry in 86. In all cases of reflux, CDUS visualised the passage of contrast material from the stomach into the abdominal and middle and distal third of the thoracic oesophagus, enabling assessment of the segment of oesophagus involved by the reflux. Compared with pH-metry, CDUS had a sensitivity of 98% (p0.0001 with McNemar's test).In consideration of the results obtained and particularly of the low level of invasiveness, contrast-enhanced CDUS could be used to monitor children undergoing medical or surgical treatment for the complications of gastro-oesophageal reflux disease.

The chapter describes the characteristics of the Experiential-Cognitive Therapy (ECT) protocol for Panic Disorder and Agoraphobia. The goal of ECT is to decondition fear reactions, to modify misinterpretational cognition related to panic symptoms and to reduce anxiety symptoms. This is possible in an average of eight sessions of treatment plus an assessment phase and booster sessions, through the integration of Virtual Experience and traditional cognitive-behavioral techniques. We decided to employ the techniques included in the cognitive-behavioral approach because they showed high levels of efficacy. Through virtual environments we can gradually expose the patient to feared situation: virtual reality consent to re-create in our clinical office a real experiential world. The patient faces the feared stimuli in a context that is nearer to reality than imagination. For ECT we developed the Virtual Environments for Panic Disorders--VEPD--virtual reality system. VEPD is a 4-zone virtual environment developed using the Superscape VRT 5.6 toolkit. The four zones reproduce different potentially fearful situations--an elevator, a supermarket, a subway ride, and large square. In each zone the characteristics of the anxiety-related experience are defined by the therapist through a setup menu.

The emergence of new shared media, such as the Internet and virtual reality are changing the ways in which people relate, communicate, and live. Health care, and in particular clinical psychology, is one of the areas that could be most dramatically reshaped by these new technologies. To exploit and understand this potential is the overall goal of the "Telemedicine and Portable Virtual Environment in Clinical Psychology"--VEPSY UPDATED--an European Community funded research project (IST-2000-25323, http://www.vepsy.com) whose specific goal is the development of different PC based virtual reality modules to be used in clinical assessment and treatment. In particular the developed modules have been using to address the following pathologies: anxiety disorders; male impotence and premature ejaculation; obesity, bulimia and binge-eating disorders. The chapter details the general technical and clinical characteristics of the developed modules.

Agoraphobia consists of a group of fears of public places such as going outside, using public transportation and being in public places, which cause serious interference in daily life. Many studies demonstrated the effectiveness of a multicomponent cognitive-behavioral treatment strategy for panic disorder with agoraphobia. The traditional protocol involves a mixture of cognitive and behavioral techniques which are intended to help patients identify and modify their dysfunctional anxiety-related thoughts, beliefs and behavior. Emphasis is placed on reversing the maintaining factors identified in the cognitive and behavioral patterns. We use Virtual Reality (VR) to support Panic Disorder treatment. The preliminary treatment protocol for Panic Disorder and Agoraphobia, named Experiential-Cognitive Therapy (ECT), was developed at the Applied Technology for Neuro-Psychology Lab of Istituto Auxologico Italiano, Verbania, Italy, in cooperation with the Psychology Department of the Catholic University of Milan, Italy. The actual version included the efforts of researchers from the Center for Advanced Multimedia Psychotherapy, California School of Professional Psychology, San Diego (CA), USA, and from the Seoul Paik Hospital, Inje University, Seoul, Korea. The goal of ECT is to decondition fear reactions, to modify misinterpretational cognition related to panic symptoms and to reduce anxiety symptoms. The characteristics of the approach will be presented through the description of the clinical protocol.

Virtual Reality Environments for Psychoneurophysiological Assessment and Rehabilitation-is an European Community funded project (Telematics for health-HC 1053 http:/(/)www.etho.be/ht_projects/vrepar/) whose aim is: to develop a PC based virtual reality system (PC-VRS) for the medical market that can be marketed at a price which is accessible to its possible end-users (hospitals, universities and research centres) and which would have the modular, connectability and interoperability characteristics that the existing systems lack; to develop three hardware/software modules for the application of the PC VRS in psychoneurophysiological assessment and rehabilitation. The chosen development areas are eating disorders (bulimia, anorexia and obesity), movement disorders (Parkinson's disease and torsion dystonia) and stroke disorders (unilateral neglect and hemiparesis). This paper presents the rationale of the different approaches and the methodology used.

Screening for blood IgE mediated allergy (atopy) by the RAST technique among 76 people working in a coffee processing factory showed rather unexpected findings: although we found a prevalence of positivity (17.1%) to the common airborne antigens (pollens, mites, cat, Alternaria tenuis) which was close to the prevalence of atopy among normal adults in our area (19.3%), only one case of allergy to green coffee and two cases to castor bean came to the fore. Specific IgG4 antibodies were measured only for castor bean and green coffee, and rather elevated figures were found: green coffee 17.1%, castor bean 13.1%. The occurence of positive RASTs to castor bean is more likely to be due to contamination of the bags containing green coffee. The low prevalence of RAST positivities to green coffee, and the elevated specific IgG4 antibodies to both castor bean and green coffee antigens, raise several possibilities which are discussed; however, all the subjects but one having elevated specific IgG4 levels to green coffee worked in more exposed areas. Probably IgG4 antibodies in this particular case are acting as blocking antibodies.

The main goal of this contribution is to present a methodological framework to study Networked Flow, a bio-psycho-social theory of collective creativity applying it on creative processes occurring via a computer network. First, we draw on the definition of Networked Flow to identify the key methodological requirements of this model. Next, we present the rationale of a mixed methodology, which aims at combining qualitative, quantitative and structural analysis of group dynamics to obtain a rich longitudinal dataset. We argue that this integrated strategy holds potential for describing the complex dynamics of creative collaboration, by linking the experiential features of collaborative experience (flow, social presence), with the structural features of collaboration dynamics (network indexes) and the collaboration outcome (the creative product). Finally, we report on our experience with using this methodology in blended collaboration settings (including both face-to-face and virtual meetings), to identify open issues and provide future research directions.

This paper provides an empirical research about virtual reality users’ avatar embodiment. According to literature, users that are embodied/incarnated in their avatars show a tendency to perceive avatars’ failures as their own mistakes. Therefore, they are likely to monitor their own hands on the device they’re using (e.g.: keyboard) when they perceive a failure in the interaction (a behavior named “focus shift”). We hypothesize that the phenomenon of focus shift is sensitive to different types of failures that can affect the multiple elements involved in the interaction. Thirty participants guided an avatar through a videogame-like virtual environment. The participants were exposed to three experimental manipulations (defective keyboard, defective avatar, defective virtual environment). We counted the number of focus shifts that participants showed in response to these three manipulated anomalies. Results showed a significantly high number of focus shifts in the condition with defective virtual environment. The findings are discussed with reference to mediation theory, explaining the role of action/feedback matching in the phenomenon of avatar embodiment.

International audience; The general aim of the present study was to investigate the effect of an interactive aerial view of the experienced environment during the encoding and retrieving of spatial information on the feeling of presence. Our findings showed that this real-time interactive aerial view (both small and large) during the encoding and retrieval of spatial information seems to led to a greater sense of presence. It is argued that the use of this aerial view, which provides a real-time allocentric viewpoint-dependent spatial representation, would ease the translation of a stored allocentric representation into an egocentric one, and this process, consequently, would help individuals to feel present in space.

The aim of this study was to establish whether virtual reality (VR) exposure to food cues is able to produce craving levels consistent with state-craving and trait-craving as assessed by the Spanish and Italian versions of the State and Trait Food Craving Questionnaires (FCQ-T/S). The results were compared in 40 patients with eating disorders (17 with binge eating disorder, 23 with bulimia nervosa) and 78 healthy control subjects without eating disorders. Controls and patients with higher levels of trait-craving and state-craving both showed a greater desire to eat during VR exposure. Results also showed that trait and state craving assessed by FCQ-T/S were able to predict the total mean craving experienced during exposure to the VR software in both clinical and control samples. These findings present preliminary evidence about the validity of a new virtual reality-based application for cue- exposure treatment in patients with eating disorders.

Virtual Reality (VR) is increasingly being used in combination with psycho-physiological measures to improve assessment of distress in mental health research and therapy. However, the analysis and interpretation of multiple physiological measures is time consuming and requires specific skills, which are not available to most clinicians. To address this issue, we designed and developed a Decision Support System (DSS) for automatic classification of stress levels during exposure to VR environments. The DSS integrates different biosensor data (ECG, breathing rate, EEG) and behavioral data (body gestures correlated with stress), following a training process in which self-rated and clinical-rated stress levels are used as ground truth. Detected stress events for each VR session are reported to the therapist as an aggregated value (ranging from 0 to 1) and graphically displayed on a diagram accessible by the therapist through a web-based interface.

Modifications of language processing can be observed both in normal aging and in the most common forms of degenerative dementia, such as Alzheimer's disease and the spectrum of frontotemporal dementias. The present experiment tests at the same time semantic and syntactic aspects of language processing in patients with frontotemporal dementia, using an online paradigm that allows researchers to evaluate the real linguistic competence of the patients.

We report the occurrence of human herpesvirus (HHV)-8 primary infection in an adult male kidney recipient. Four months after transplantation, the patient developed visceral Kaposi sarcoma, and 1 month later he presented with progressive and severe peripheral cytopenia, in the presence of a normocellular or hypercellular bone marrow (BM) with hemophagocytosis. HHV-8 was the sole pathogen detected by polymerase chain reaction either in the serum or in the BM. HHV-8 latent nuclear antigen was detected in immature progenitor cells from the BM. Immunosuppressive therapy was reduced, and the patient was treated with foscarnet for 2 weeks, leading to a dramatic normalization of blood cell counts, concomitantly with the disappearance of HHV-8 viremia. At the end of antiviral therapy, the patient received chemotherapy, and Kaposi sarcoma regressed in 2 months. Severe peripheral cytopenia may be a posttransplant complication after HHV-8 infection, for which treatment with foscarnet seems appropriate.

Food choices are influenced by many factors, perhaps the most important being availability. However, the desire to consume one item over another may be viewed as an outcome of sensory hedonic likes, situation and current internal state. In a previous preliminary report, an improvement of joy and mood, associated with good data of digestibility and palatability, was observed in a group of 30 healthy female subjects who consumed a coffee-flavoured iced dessert immediately after a standardized meal. The aim of this study is to confirm the results previously obtained in a smaller population and to investigate whether any differences between male and female subjects could be observed concerning the digestive process and emotional status. One hundred volunteers, after ENT and psychological assessment, were asked to fill out a Psycho-Emotional Questionnaire to assess their basal emotional pattern before the consumption of an iced coffee-flavoured dessert after a standard meal. After the meal they completed an Organoleptic-Sensory questionnaire, a Dynamic Digestibility questionnaire and again the Psycho-Emotional Questionnaire. In our study, most of the 100 subjects found the tested coffee-flavoured iced dessert pleasant according to the Organoleptic-Sensorial Questionnaire (OSQ), in terms of taste, aspect, texture and smell; moreover, the Dynamic Digestibility Questionnaire (DDQ) showed a good digestive experience in 71 subjects. According to the Psycho-Emotional Questionnaire (PEQ), an improvement of joy, activation and mood, associated with good data of digestibility and palatability was recorded. All these observations are statistically significant and the results seem to show a positive correlation between pleasure in eating such a product and emotional status. No statistically significant differences were recorded between male and female subjects.

During the last 15 years, virologic and immunologic studies have provided a series of valuable clues on the modalities of gamma-herpesvirus-induced oncogenesis, which do not only consist of the direct subversion of intracellular signaling pathways, leading to a frank neoplastic molecular network in the infected cell, but also rely on viral manipulations of the cellular and cytokine microenvironment, especially in conditions of immunodeficiency in the host. At the virus-host interface, something iniquitous, strikingly favoring the aggressive expansion of human herpesvirus 8-infected lympho-endothelial clones, known as Kaposi's sarcoma, often occurs in different types of immunocompromised patients, able to establish a deleterious "pro-Kaposi's sarcoma" neo-angiogenic inflammatory network. However, these patients may control - or even resolve - the neoplastic burden as soon as an immunologic reassessment restores functional anti-Kaposi's sarcoma immune responses and reconstitutes a proper inflammatory environment. Indeed, the occurrence of iatrogenic Kaposi's sarcoma remissions, after the reduction or switch of immunosuppressive regimens, strongly suggests that the reset of immunologic constraints characterizing the Kaposi's sarcoma onco-pathogenic system may be sufficient to inhibit human herpesvirus 8-positive lympho-endothelial proliferations. Accordingly, immunologic reports all underline the pivotal protective role of anti-human herpesvirus 8 memory T-cells (harmonically, both CD8+ and CD4+ subsets), thus definitely implying a general requirement for an effective, antiviral immuno-inflammatory environment, based on correct and productive interactions between different compartments of dendritic, myeloid, and specific T-cells, in order to achieve and maintain optimal control on human herpesvirus 8-associated antigenic stimulations and Kaposi's sarcoma disease. In this review, we recapitulate some remarkable features about the outstanding immunologic issue raised by human herpesvirus 8-driven neoplastic outgrowths in immunodeficient patients, and in particular, we discuss the emerging view of Kaposi's sarcoma as an atypical neoplastic process, tightly dependent on immune system dynamics. It is conceivable that functional dissection of the specific immune responses, capable to cope with human herpesvirus 8, and further definitions of a global inflammatory profile with protective activity against Kaposi's sarcoma outbreaks, will eventually foster immunologic monitoring protocols during the follow-up of AIDS and posttransplant patients, either preventing or treating human herpesvirus 8-related tumors by multifunctional immunomodulation or prompt development of adoptive immunotherapeutic approaches.

Epidemiological studies on the pollens responsible for allergic diseases throughout Italy are lacking. Routine diagnostic panels consist prevalently of grass, Parietaria, weeds, birch, olive and mugwort. Considering the great variety of Italian geographical areas and the observation of the growing allergological importance of new botanical species (e.g., ambrosia), a survey on pollen species considered "minor" was necessary. A panel of "emerging" pollens (birch, hazelnut, alder, hornbeam, cypress, ragweed) and a routine panel were used to skin prick test 2,934 consecutive outpatients with respiratory pathology of suspected allergic origin, in 21 centers across Italy. A specific questionnaire was compiled. It was found that 20.1% of patients did not react to allergens tested, 28.2% were positive for at least one emerging pollen and 51.7% did not react to emerging pollens but tested positive for at least one allergen from the routine panel. The prevalence of single pollen species was related to geographical areas. Ragweed pollen was shown to provoke asthma much more frequently than other pollens. Hitherto scarcely considered pollens play a considerable role in causing allergic diseases in Italy. In the great majority of patients, positivity for these pollens was associated with positivity to the better recognized group of pollen allergens, although in some cases they were the primary pathogenic agent. We suggest that these more recently considered allergens be included in routine diagnostic panels.

Bariatric surgery is an operation on the stomach and/or intestines that helps patients with extreme obesity to lose weight. Even if bariatric surgery, compared with traditional obesity treatment, is more effective in reducing BMI, this approach does not achieve equal results in every patient. More, following bariatric surgery common problems are body image dissatisfaction and body disparagement: there is a significant difference between the weight loss clinicians consider successful (50% of excess weight) and the weight loss potential patients expect to achieve (at least 67% of the excess weight). The paper discusses the possible role of virtual reality (VR) in addressing this problem within an integrated treatment approach. More, the clinical case of a female bariatric patient who experienced body dissatisfaction even after a 30% body weight loss and a 62% excess body weight loss, is presented and discussed.

The purpose of this study was to establish ecological validity and initial construct validity of the Virtual Reality (VR) version of the Multiple Errands Test (MET) (Shalliceamp; Burgess, 1991; Fortin et al., 2003) based on the NeuroVR software as an assessment tool for executive functions. In particular, the MET is an assessment of executive functions in daily life, which consists of tasks that abide by certain rules and is performed in a shopping mall-like setting where items need to be bought and information needs to be obtained. The study population included three groups: post-stroke participants (n = 5), healthy, young participants (n = 5), and healthy, older participants (n = 5). Specific objectives were (1) to examine the relationships between the performance of three groups of participants in the Virtual Multiple Errands Test (VMET) and at the traditional neuropsychological tests employed to assess executive functions and (2) to compare the performance of post-stroke participants to those of healthy, young controls and older controls in the VMET and at the traditional neuropsychological tests employed to assess executive functions.

We describe the main features and preliminary evaluation of Positive Technology, a free mobile platform for the self-management of psychological stress (http://positiveapp.info/). The mobile platform features three main components: (i) guided relaxation, which provides the user with the opportunity of browsing a gallery of relaxation music and video-narrative resources for reducing stress; (ii) 3D biofeedback, which helps the user learning to control his/her responses, by visualizing variations of heart rate in an engaging 3D environment; (iii) stress tracking, by the recording of heart rate and self-reports. We evaluated the Positive Technology app in an online trial involving 32 participants, out of which 7 used the application in combination with the wrist sensor. Overall, feedback from users was satisfactory and the analysis of data collected online indicated the capability of the app for reducing perceived stress levels. A future goal is to improve the usability of the application and include more advanced stress monitoring features, based on the analysis of heart rate variability indexes.

The differential diagnosis between lateral ectopic thyroid tissue with orthotopic normal gland and metastatic thyroid carcinoma is challenging. Lateral cervical site is a very rare location for ectopic tissue since only a few cases have been reported. The peculiarity of this clinical case is the finding of a thyroid carcinoma forty years after surgical resection of the ectopic thyroid lesion. This asynchronous association, never reported in literature, raises the question of the differential diagnosis between a true ectopic aberrant thyroid and an early lymph node metastasis from an occult thyroid carcinoma, evident in the primitive site many years later. Several elements, which will be matter of discussion, seem to favour the latter hypothesis.This case, although isolated, suggests that any lateral cervical mass, comprising thyroid tissue, should be regarded as a metastasis of thyroid carcinoma until proven otherwise. Carefull investigation of thyroid gland is mandatory.

Over the last 25 years, virtual reality (VR) has offered innovative solutions for targeting different key symptoms of eating disorders: from craving to negative emotions, from attentional biases to body dissatisfaction. The present narrative review assesses the existing literature in these areas trying to identify their different levels of clinical evidence. Specifically, the review presents four clinical approaches based upon VR and their implications in the treatment of eating disorders: VR cue exposure, VR reference frame shifting, VR for correcting body distortions and attentional biases. In general, existing findings demonstrate the clinical value of VR. On one side, the present review suggests that two VR-based techniques—VR exposure and reference frame shifting—have a significant research support and provide a possible advantage over traditional cognitive-behavioural therapy (CBT) for bulimia nervosa and binge eating disorder. On the other side, two emerging VR applications—multisensory body illusions and the use of VR for the modification of attentional biases—even if supported by preliminary data still need further research.

Background Healthcare workers represent one of the most affected categories by the adverse effects of the COVID-19 pandemic on mental health. Excessive stress and anxiety are critical factors that could compromise work performance. Besides, high levels of stress and anxiety may have long-term physical and psychological consequences. Recent studies investigated virtual reality to reduce stress and anxiety among healthcare workers during the COVID-19 pandemic. However, the proposed virtual reality interventions have important limitations related to their location (i.e., research lab and hospitals) and content (i.e., virtual experiences only for relaxation). Within this context, this randomized controlled trial aims to investigate the efficacy and acceptability of a brief home-based virtual reality training for managing stress and anxiety during the COVID-19 crisis in a sample of Italian healthcare workers. Methods The study is a randomized controlled trial. It includes two groups of 30 individuals recruited from healthcare workers: (1) the experimental group and (2) the control group. Participants in the experimental group will receive a training consisting of three home sessions performed in a week. In each session, participants will try through an immersive virtual reality standalone system (i.e., Oculus Quest 2) a virtual psychoeducation experience on stress and anxiety (i.e., MIND-VR). Subsequently, they will try the virtual relaxation content (i.e., The Secret Garden). The control group will receive no training and will be reassessed one week and one month after the initial evaluation. Discussion If the proposed brief home-based virtual reality training will result helpful and easy to use, it could become an empirically assessed viable option for protecting healthcare workers’ mental health both during the COVID-19 pandemic and once it will be over. Furthermore, the intervention might be easily adapted for other categories of people who need support in managing stress and anxiety. Trial registration ClinicalTrials.gov NCT04611399.

When facing a negative event, people implement different strategies to regulate ongoing emotions. Although the previous literature has suggested that the emotional intensity of a negative episode is associated with the characteristics of the subsequent autobiographical memory, it is still unknown whether emotion regulation (ER) moderates this relationship. In the present study, we provided undergraduate students with a smartphone-based diary to report a negative episode immediately after its occurrence and rate the momentary use of two ER strategies: cognitive reappraisal and rumination. To explore autobiographical memory, two “surprise” recall tasks were performed one week and one month after the event. According to the results, cognitive reappraisal was linked with better memory performances, and a tendency to retrospectively underestimate the negativity of highly intense events was observed only in participants adopting high rates of this strategy. Conversely, intense rumination was found to be associated with less detailed memories of emotionally intense events, as well as with higher emotional involvement with negative episodes over time, regardless of their intensity. Together, our results support the maladaptive role of rumination and the adaptive influence of cognitive reappraisal on autobiographical memory.

Is virtual reality (VR) already a reality in behavioral health? To answer this question, a meta-review was conducted to assess the meta-analyses and systematic and narrative reviews published in this field in the last twenty-two months. Twenty-five different articles demonstrated the clinical potential of this technology in both the diagnosis and the treatment of mental health disorders: VR compares favorably to existing treatments in anxiety disorders, eating and weight disorders, and pain management, with long-term effects that generalize to the real world. But why is VR so effective? Here, the following answer is suggested: VR shares with the brain the same basic mechanism: embodied simulations. According to neuroscience, to regulate and control the body in the world effectively, the brain creates an embodied simulation of the body in the world used to represent and predict actions, concepts, and emotions. VR works in a similar way: the VR experience tries to predict the sensory consequences of an individual's movements, providing to him/her the same scene he/she will see in the real world. To achieve this, the VR system, like the brain, maintains a model (simulation) of the body and the space around it. If the presence in the body is the outcome of different embodied simulations, concepts are embodied simulations, and VR is an embodied technology, this suggests a new clinical approach discussed in this article: the possibility of altering the experience of the body and facilitating cognitive modeling/change by designing targeted virtual environments able to simulate both the external and the internal world/body.

Objective Ampulla of Vater carcinoma (AVC) has a broad spectrum of different prognoses. As such, new moderators of survival are urgently needed. We aimed at clarifying the prognostic role of perineural invasion in AVC. Methods Using PubMed and SCOPUS databases, we conducted the first systematic review and meta-analysis on this topic. Results Analyzing 29 articles for a total of 2379 patients, we found that the presence of perineural invasion increased the risk of all-cause mortality more than 2 times (relative risk [RR], 2.07; 95% confidence interval [CI], 1.78-2.42 [P < 0.0001]; hazard ratio [HR], 2.72; 95% CI, 1.86-3.97 [P < 0.0001]), of cancer-specific mortality more than 6 times (RR, 6.12; 95% CI, 3.25-11.54 [P < 0.0001]; HR, 6.59; 95% CI, 2.29-3.49 [P < 0.0001]), and of recurrence more than 2 times (RR, 2.63; 95% CI, 1.89-3.67 [P < 0.0001]; HR, 2.54; 95% CI, 1.24-5.21 [P = 0.01]). Conclusions Perineural invasion is strongly associated with a poorer prognosis in AVC, influencing both survival and risk of recurrence. It should be reported in the final pathology report and should be taken into account by future oncologic staging systems, identifying a group of AVC with a more malignant biological behavior. © Wolters Kluwer Health, Inc.

The persistence of the coronavirus-caused respiratory disease (COVID-19) and the related restrictions to mobility and social interactions are forcing a significant portion of students and workers to reorganize their daily activities to accommodate the needs of distance learning and agile work (smart working). What is the impact of these changes on the bosses/teachers' and workers/students' experience? This article uses recent neuroscience research findings to explore how distance learning and smart working impact the following three pillars that reflect the organization of our brain and are at the core of school and office experiences: (a) the learning/work happens in a dedicated physical place; (b) the learning/work is carried out under the supervision of a boss/professor; and (c) the learning/work is distributed between team members/classmates. For each pillar, we discuss its link with the specific cognitive processes involved and the impact that technology has on their functioning. In particular, the use of videoconferencing affects the functioning of Global Positioning System neurons (neurons that code our navigation behavior), mirror neurons, self-attention networks, spindle cells, and interbrain neural oscillations. These effects have a significant impact on many identity and cognitive processes, including social and professional identity, leadership, intuition, mentoring, and creativity. In conclusion, just moving typical office and learning processes inside a videoconferencing platform, as happened in many contexts during the COVID-19 pandemic, can in the long term erode corporate cultures and school communities. In this view, an effective use of technology requires us to reimagine how work and teaching are done virtually, in creative and bold new ways.

BackgroundMetabolic dysfunction-associated fatty liver disease (MAFLD) represents a new inclusive definition of the whole spectrum of liver diseases associated to metabolic disorders. The main objective of this study was to compare patients with MAFLD and non-MAFLD with hepatocellular carcinoma (HCC) included in a nationally representative cohort.MethodsWe analysed 6882 consecutive patients with HCC enrolled from 2002 to 2019 by 23 Italian Liver Cancer centres to compare epidemiological and future trends in three subgroups: pure, single aetiology MAFLD (S-MAFLD); mixed aetiology MAFLD (metabolic and others, M-MAFLD); and non-MAFLD HCC.ResultsMAFLD was diagnosed in the majority of patients with HCC (68.4%). The proportion of both total MAFLD and S-MAFLD HCC significantly increased over time (from 50.4% and 3.6% in 2002–2003, to 77.3% and 28.9% in 2018–2019, respectively, pConclusionsThe prevalence of MAFLD HCC in Italy is rapidly increasing to cover the majority of patients with HCC. Despite a less favourable cancer stage at diagnosis, patients with MAFLD HCC have a lower risk of HCC-related death, suggesting reduced cancer aggressiveness.

The aim of this study is to investigate the effectiveness of a novel self-administered at-home daily virtual reality (VR)-based intervention (COVID Feel Good) for reducing the psychological burden experienced during the COVID-19 lockdown in Italy. A total of 40 individuals who had experienced at least two months of strict social distancing measures followed COVID Feel Good between June and July 2020 for one week. Primary outcome measures were depression, anxiety, and stress symptoms, perceived stress levels, and hopelessness. Secondary outcomes were the experienced social connectedness and the level of fear experienced during the COVID-19 pandemic. Linear mixed-effects models were fitted to evaluate the effectiveness of the intervention. Additionally, we also performed a clinical change analysis on primary outcome measures. As concerning primary outcome measures, participants exhibited improvements from baseline to post-intervention for depression levels, stress levels, general distress, and perceived stress (all p &lt, 0.05) but not for the perceived hopelessness (p = 0.110). Results for the secondary outcomes indicated an increase in social connectedness from T0 to T1 (p = 0.033) but not a significant reduction in the perceived fear of coronavirus (p = 0.412). Among these study variables, these significant improvements were maintained from post-intervention to the 2-week follow-up (p &gt, 0.05). Results indicated that the intervention was associated with good clinical outcomes, low-to-no risks for the treatment, and no adverse effects or risks. Globally, evidence suggests a beneficial effect of the proposed protocol and its current availability in 12 different languages makes COVID Feel Good a free choice for helping individuals worldwide to cope with the psychological distress associated with the COVID-19 crisis, although large scale trials are needed to evaluate its efficacy.

The past 10 years have seen the development and maturation of several digital technologies that can have a critical role to enhancement of happiness and psychological well-being. In particular, the past decade has seen the emergence of a new paradigm: "Positive Technology," the scientific and applied approach to the use of technology for improving the quality of our personal experience. In this article we discussed the potential of Positive Technology to augment and enhance the existing strategies for generating psychological well-being during the COVID-19 pandemic. In particular different positive technologies-m-Health and smartphone apps, stand-alone and social virtual reality, video games, exergames, and social technologies-have the potential of enhancing different critical features of our personal experience-affective quality, engagement/actualization, and connectedness-that are challenged by the pandemic and its social and economic effects. In conclusion, although the focus of tackling the direct impact of COVID-19 is important, positive technologies can be extremely useful to reduce the psychological burden of the pandemic and to help individuals in flourishing even during difficult and complex times.

We review neuroimaging research investigating self-referential processing (SRP), that is, how we respond to stimuli that reference ourselves, prefaced by a lexical-thematic analysis of words indicative of "self-feelings". We consider SRP as occurring verbally (V-SRP) and non-verbally (NV-SRP), both in the controlled, "top-down" form of introspective and interoceptive tasks, respectively, as well as in the "bottom-up" spontaneous or automatic form of "mind wandering" and "body wandering" that occurs during resting state. Our review leads us to outline a conceptual and methodological framework for future SRP research that we briefly apply toward understanding certain psychological and neurological disorders symptomatically associated with abnormal SRP. Our discussion is partly guided by William James' original writings on the consciousness of self.

ObjectiveStandard treatment in locally-advanced cervical cancer is external beam radiotherapy concomitant with platinum-based chemotherapy, followed by brachytherapy. The goal of our study was to determine whether an intensity modulated radiation therapy (IMRT) boost is feasible in patients unfit for brachytherapy.MethodsWe retrospectively analyzed data of 25 patients unfit for brachytherapy with median age 55 years (range, 30–82) with locally-advanced/metastatic cervical cancer who underwent external beam radiotherapy to pelvis ±para-aortic lymph nodes and sequential IMRT boost between July 2014 and December 2017. Total dose of 45–50.4 Gy in 25–28 fractions (1.8 Gy/fraction) was administered to the cervix, uterus, parametria, ovaries, vaginal tissues (based on vaginal extension), involved lymph nodes, or relevant draining lymph-nodal groups. Para-aortic nodes were included if involved at radiological staging or if common iliac nodes were positive. The IMRT boost included all residual tumor after external beam radiotherapy identified on MRI. The Kaplan–Meier method was used to calculate 2 years' overall survival, 2 years' progression-free survival, and 2 years' local control. Overall survival- and progression-free survival were calculated considering the starting of radiotherapy or neo-adjuvant chemotherapy if prescribed, while local control was calculated from the end of radiotherapy.ResultsMedian radiation dose to pelvis ±para-aortic lymph nodes was 50.4 Gy (45–50.4), boost treatment was homogeneously performed to a total dose of 25 Gy in five fractions every other day.After a median follow-up of 26 months (range, 4–77), tumor persistence at cervix at 6 months from the end of radiotherapy or local recurrence occurred in five women (20%), eight (32%) experienced a further distant progression (two of them had also tumor persistence). Two-year local control and overall survival rates for all stages were 78% and 67%, respectively. According to Common Terminology Criteria for Adverse Events v.4 scoring criteria, 10 patients experienced gastrointestinal and/or genitourinary grade G1-2 acute toxicity. G2 rectal late toxicity requiring laser-coagulation was registered in two patients, there were no gastrointestinal and/or genitourinary acute or late toxicities≥G3.ConclusionThe combination of external beam radiotherapy and brachytherapy remains the standard of care, however our preliminary data show the feasibility of IMRT boost in terms of toxicity with promising results in terms of local control and overall survival.

It is noted that the perceptual experience of body and space can be modulated by changing the action capabilities or by manipulating the perceived body dimensions through a multisensory stimulation. This study adds to pre-existing literature by investigating the alterations in bodily experience following embodiment to both enlarged and shrunked bodies, while participants actively navigated in a virtual environment. A normal-sized body served as a reference condition. After each embodied navigation, participants estimated the height and width of three different body parts. Results revealed that the embodiment over shrunked body induced a significant reduction in participants’ body image, while no changes were reported after the embodiment over the enlarged body. Findings were discussed in terms of previous literature exploring the constraints implicated in the ownership over different bodies.

Oil Red O is a useful tool to assess donor liver steatosis on frozen sections during transplantation. Steatosis is a frequent finding in liver evaluation during transplantation, accounting for 9% to 26% of biopsied donor liver. The degree of macrovesicular steatosis is classified as mild, moderate, and severe; the latter is considered an absolute contraindication to liver transplantation because it is associated with poor allograft outcome. Because of the scarcity of organs, there is a debate whether livers with less severe macrovesicular steatosis are still suitable for transplant. Consequently, tools or methods that allow a more accurate intraoperative assessment of steatosis on frozen sections are mandatory. The aim of this study is to improve intraoperative evaluation of steatosis during transplantation using Oil Red O stain on liver biopsies. Methods Twenty consecutive liver biopsies of donors were collected during transplantation procedures from September 2017 to February 2018 at the Institute of Pathology of the University and Hospital Trust of Verona, Italy. Each liver biopsy was cut at a different thickness (3, 5, and 8 μm) and stained with both Oil Red O and conventional hematoxylin and eosin for intraoperative consultation. The degree (percentage of hepatocytes involved) of fatty changes was recorded. The results obtained during the intraoperative consultation were finally compared with the formalin-fixed and paraffin-embedded permanent section. Results Assessment of steatosis on hematoxylin and eosin frozen sections was reported as mild in 17 cases (85%), moderate in 2 cases (10%) and severe in 1 case (5%). Oil Red O frozen sections reported the following results: mild steatosis in 16 cases (80%), moderate in 2 cases (10%), and severe in 2 cases (10%). The percentage of liver steatosis obtained with Oil Red O was consistent in all cases with that of the permanent sections. The staining procedure for Oil Red O required approximately 18 minutes. Conclusions Oil Red O special stain is a fast and inexpensive tool to improve the assessment of steatosis on frozen biopsies during liver transplantation.

A growing body of evidence demonstrated that it is feasible to induce ownership over an artificial body to alter bodily experience. However, several uncharted aspects about full-body illusion applications need to be tackled before a complete exploitation of these methods in clinical practice. This work is devoted to explore possible individual age-related differences in shaping changes in body representations induced with a full-body illusion. A total of 40 women were divided into two different age groups according to the median of the variable age. Participants estimated the width of three different body parts (i.e., shoulders, abdomen, and hips) before the entire illusion was induced (baseline), and after the synchronous and the asynchronous conditions. Results revealed that 26-to-55-year-old participants were more resistant to changes induced by the bodily illusion, whereas 19-to-25-year-old participants underestimated their bodies after both conditions. The findings were discussed in terms of the literature exploring age differences in responses to bodily illusion, which could suggest a Bayesian mechanism underlying these individual differences.

Virtual reality technologies allow for controlled simulations of affectively engaging background narratives. These virtual environments offer promise for enhancing emotionally relevant experiences and social interactions. Within this context virtual reality can allow instructors, therapists, neuropsychologists, and service providers to offer safe, repeatable, and diversifiable interventions that can benefit assessments and learning in both typically developing children and children with disabilities. Research has also pointed to virtual reality’s capacity to reduce children’s experience of aversive stimuli and reduce anxiety levels. While there are a number of purported advantages of virtual reality technologies, challenges have emerged. One challenge for this field of study is the lack of consensus on how to do trials. A related issue is the need for establishing the psychometric properties of virtual reality assessments and interventions. This review investigates the advantages and challenges inherent in the application of virtual reality technologies to pediatric assessments and interventions.

Purpose: Virtual reality (VR) technologies have been proposed as a new tool able to improve on in vivo exposure in patients with eating disorders. This study assessed the validity of a VR-based software for cue exposure therapy (CET) in people with bulimia nervosa (BN) and binge eating disorder (BED). Methods: Fifty eight outpatients (33 BN and 25 BED) and 135 healthy participants were exposed to 10 craved virtual foods and a neutral cue in four experimental virtual environments (kitchen, dining room, bedroom, and cafeteria). After exposure to each VR scenario, food craving and anxiety were assessed. The frequency/severity of episodes of uncontrollable overeating was also assessed and body mass index was measured prior to the exposure. Results: In both groups, craving and anxiety responses when exposed to the food-related virtual environments were significantly higher than in the neutral-cue virtual environment. However, craving and anxiety levels were higher in the clinical group. Furthermore, cue-elicited anxiety was better at discriminating between clinical and healthy groups than cue-elicited craving. Conclusions: This study provides evidence of the ability of food-related VR environments to provoke food craving and anxiety responses in BN and BED patients and highlights the need to consider both responses during treatment. The results support the use of VR-CET in the treatment of eating disorder patients characterized by binge-eating and people with high bulimic symptoms

Background: Topographical disorientation (TD) refers to a particular condition which determines the loss of spatial orientation, both in new and familiar environments. TD and spatial memory impairments occur relatively early as effect of cognitive decline in aging, even in prodromal stages of dementia, namely mild cognitive impairment (MCI). Aims: (a) To show that components linked to the recall of familiar spatial knowledge are relatively spared with respect to the learning of unfamiliar ones in normal aging, while they are not in MCI, and (b) to investigate gender differences for their impact on egocentric and allocentric frames of reference. Method: Forty young participants (YC), 40 healthy elderly participants (HE), 40 elderly participants with subjective memory complaints (SMC), and 40 elderly with probable MCI were administered with egocentric and allocentric familiar tasks, based on the map of their hometown, and with egocentric and allocentric unfamiliar tasks, based on new material to be learned. A series of general linear models were used to analyze data. Results: No group differences were found on egocentric task based on familiar information. MCI performed worse than the other groups on allocentric tasks based on familiar information (YC = HE = SMC > MCI). Significant differences emerged between groups on egocentric and allocentric tasks based on unfamiliar spatial information (YC > HE = SMC > MCI). A gender difference was found, favoring men on allocentric unfamiliar task. Conclusion: Familiarity of spatial memory traces can represent a protective factor for retrospective components of TD in normal aging. Conversely, using newly learned information for assessment may lead to overestimating TD severity.
