Introduction: Bulimic episodes experienced by patients with Binge Eating Disorder (BED) might be sustained by an enhanced behavioral propensity to approach food stimuli., Methods: To test this hypothesis, automatic approach avoidance tendencies toward high-calorie foods (HCF), low-calorie foods (LCF), and neutral objects were assessed in a group of 23 patients with BED, and their performance was compared to the one of 17 patients with obesity without BED and a group of 32 normal weight participants. All participants performed a mobile approach-avoidance task in which they were required to approach and avoid different stimuli by respectively pulling their phone toward themselves or pushing it away. Reaction times were analyzed., Results: Results showed a significant three-way interaction between group, type of movement and stimulus. Post-hoc analyses revealed that all the groups displayed an approach bias toward HCF. Patients with BED and healthy controls also displayed an approach bias toward LCF, a bias that was absent in obese individuals without BED. Moreover, patients with BED were faster in approaching food stimuli, both HCF and LCF, compared to healthy controls., Discussion: These behavioral tendencies are quite consistent with the real-life attitudes of both BED patients and patients with obesity and might contribute to the maintenance of unhealthy eating habits such as binging in patients with BED and high-calorie diets in patients with obesity., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Collantoni, Meregalli, Granziol, Di Vincenzo, Rossato, Giovannini, Capobianco, Zech, Vettor and Favaro.)

A change in implicit behavioural tendencies toward foods may contribute to the maintenance of calorie restriction in Anorexia Nervosa (AN). To test this hypothesis, we assessed approach-avoidance tendencies toward different categories of stimuli using a novel mobile version of the approach-avoidance task (AAT). The sample included 66 patients with restrictive AN and 84 healthy controls, all females. All participants performed the AAT in which they were required to approach or avoid stimuli (high-calorie foods, low-calorie foods, and neutral objects) by respectively pulling their phone towards themselves of pushing it away. Both the response time and the force of each movement were collected by means of the smartphone's accelerometer. The results revealed that patients with AN had a reduced tendency to approach food stimuli compared to healthy controls, who instead presented faster and stronger movements in approaching rather than avoiding foods as compared to neutral objects. This finding was particularly pronounced in patients with greater levels of malnutrition. No differences were instead observed comparing high-calorie and low-calorie foods. The observed reduction in the natural tendency to approach food stimuli is consistent with patients' eating behaviour and may contribute to the maintenance of calorie restriction, thus representing a possible target for novel therapeutic approaches., Competing Interests: Declaration of competing interest The authors have no competing financial interests to declare., (Copyright © 2024 Elsevier Ltd.

Objective: Food avoidance is central to patients with anorexia nervosa-restrictive type (AN-R). Competing accounts in experimental psychopathology research suggest that food avoidance may result from automatic, habitual responses or from elevated inhibitory control abilities. This study investigated behavioral trajectories of food avoidance in a novel virtual reality stopping task., Method: Sixty patients with AN-R and 29 healthy controls with normal weight were investigated using a novel, kinematic task in virtual reality. We recorded spatial displacement in stop- and go-trials to virtual food and control objects. Inhibitory control abilities were operationalized by the VR task in stopping performance (i.e., interrupted movement in stop-trials), whereas we also measured habitual avoidance of virtual food across both go- and stop-trials (i.e., delayed movement relative to nonfood objects)., Results: In patients with AN-R, hand displacements were shorter to food versus nonfood across stop- and go-trials, reflected in a Stimulus × Group interaction. Healthy controls showed no differences. Importantly, the food-specific effect in AN-R was identical across stop- and go-trials, indicating habitual food avoidance. Moreover, stop error rates (i.e., stop-trials with response) were lower in patients with AN-R., Discussion: The findings suggest food-specific habitual avoidance and heightened generalized inhibitory control in AN-R. The continuously delayed displacements during active hand movements across stop- and go-trials indicated the persistence of patients' avoidance of food., Public Significance: Experimental research investigates the mechanisms underlying mental disorders such as anorexia nervosa. In this study, we measured interrupted hand movements in response to food pictures or neutral pictures (shoes) in patients with anorexia nervosa and healthy controls. A virtual reality scenario was used. Findings indicated that patients were slower at approaching food, interrupted or not. Key mechanisms of food avoidance can be translated into habit-based treatment options in future research., (© 2024 The Authors.

Objective: Aversive emotions toward food and the consequences of eating are at the core of anorexia nervosa. Exposure therapy is effective to reduce anxiety and avoidance toward feared stimuli. Based on the inhibitory learning framework, this study examined the feasibility to induce social support or positive mood to enhance the impact of a single session virtual food exposure on food-related anxiety in anorexia nervosa., Method: One hundred and forty-five patients were randomized to: (1) virtual food exposure (i.e., baseline condition), (2) virtual food exposure plus positive mood induction (i.e., positive mood condition), or (3) virtual food exposure plus social support (i.e., social support condition). They completed self-report assessments of anxiety toward virtual foods, general anxiety, positive mood, social support, and hunger, before and after virtual food exposure. Number of eye gazes and touches toward foods were recorded during the virtual reality exposure., Results: Patients had lower levels of anxiety toward virtual foods in the positive mood condition, compared to the baseline condition [F (2,141)  = 4.36, p = .015; medium effect size]. They also touched food items more often in the baseline condition. No other significant changes were found., Discussion: Virtual food exposure enhanced by positive mood induction seems a feasible approach to strengthen the impact of food exposure in anorexia nervosa., Public Significance: This research contributes to the understanding of how patients with anorexia nervosa can be supported to overcome fear and anxiety around food. Virtual reality enables patients to expose themselves to difficult situations (e.g., kitchen with foods of various calorie contents) while experiencing positive stimuli, such as a loving and kind pet or a supportive avatar., (© 2024 The Authors.

In recent years, the definition, clinical characteristics, and psychological aspects of anorexia nervosa (AN) have undergone notable changes, influenced by various factors such as biology, psychology, and the environment. The COVID-19 pandemic is one such external factor that has been preliminarily identified as affecting the clinical presentation of AN. This study specifically aims to assess the alterations in psychological and medical features observed in individuals with AN during the pandemic. This study is a retrospective case review of 252 people diagnosed with AN from two different cohorts: 2010-2012 and 2021. A comparison of psychological and medical data was conducted to identify specific differences in the initial clinical evaluation. Additionally, different effects of the pandemic on age cohorts were assessed, with a focus on distinctions between adolescents and adults. Results revealed that the pandemic cohort had a higher number of new cases, with patients being younger and experiencing more severe psychological symptoms. Hospitalization rates upon first access were also elevated, but no significant differences in medical values were observed. Adolescents during the pandemic showed increased episodes of binge eating, decreased obsessive-compulsive symptoms, and greater difficulty in interoceptive awareness. This study reveals distinct differences in symptomatology among patients, with a particular focus on psychological characteristics such as impulsive behaviors and interoceptive awareness. These behavioral and interoceptive changes could have potential considerations in the treatment pathway. Further investigations are warranted to gain a deeper understanding of the evolving clinical presentation of anorexia nervosa after the pandemic.

Objective: A biased attentional processing of food stimuli may represent a disorder maintenance factor in patients with anorexia nervosa (AN). The present study aimed at investigating the temporal course of attentional deployment towards both high-calorie and low-calorie foods in patients with AN using eye-tracking., Method: Fifty-two patients with restrictive AN and 54 healthy controls (HC) performed a dot-probe task while their gaze was recorded with an eye-tracking system. The direction bias (percentage of trials in which the gaze was directed towards the food at first fixation, 500, and 1500 ms), and the duration bias (percentage of time spent looking at the food) were extracted., Results: Regarding the direction bias, a group by time interaction emerged (F = 3.29, p = 0.038): while in the control group the bias continued to increase over the course of the trial, patients with AN showed a reduction of the bias between the 500 and 1500 ms. No group differences were observed on the duration bias., Conclusions: In advanced stages of attentional deployment patients with AN start to differ from HC by diverting their attention away from food stimuli, a strategic process that may contribute to food avoidance and calorie restriction., (© 2023 The Authors.

Objective: The integration of sensory, motor, and cognitive systems is embodied cognition, according to which mind and body are not separate and distinct, and our body (and our brain, as part of the body) contributes to determining our mental and cognitive processes. In spite of limited data available, Anorexia nervosa (AN) appears as a condition in which embodied cognition is altered, in particular, if we consider bodily sensations and visuospatial information processing. We aimed to evaluate the ability to correctly identify body parts and actions in both full (AN) and atypical AN (AAN), looking at the role of the underweight status., Method: A group of 143 females (AN = 45, AAN = 43, unaffected women = 55) was enrolled. All participants performed a linguistic embodied task to evaluate the association between a picture-showing a bodily action-and a written verb. Additionally, a subsample of 24 AN participants performed a retest after stable weight recovery., Results: Both AN and AAN demonstrated an abnormal ability to evaluate the picture-written verb associations, especially if the involved bodily effectors were the same in both stimuli (i.e., pictorial and verbal) and needed a longer response time., Conclusions: Specific embodied cognition linked to body schema seems to be impaired in persons with AN. The longitudinal analysis showed a difference between AN and AAN only in the underweight condition, suggesting the presence of an abnormal linguistic embodiment. More attention should be devoted to embodiment during AN treatment to improve bodily cognition, which might, in turn, diminish body misperception., (© 2023 The Authors.

An altered automatic processing of food stimuli may contribute to the maintenance of calorie restriction in patients with restrictive Anorexia Nervosa (AN-R). The present study aimed to assess whether task-irrelevant food distractors elicited a different interference effect in the motor actions of patients with AN-R compared to healthy controls (HC). 40 patients with acute AN-R and 40 HC performed an irrelevant distractor task in which they were required to perform a reaching movement from a starting point to a green dot, while an irrelevant distractor (a high-calorie food, low-calorie food, or neutral object) was presented in the middle of the screen. Mouse trajectories and response times (RT) were recorded. The analyses conducted on the kinematic variables revealed that while the trajectories of HC veered similarly toward the three categories of stimuli, AN-R patients showed an increased deviation toward low-calorie foods and a reduced deviation toward high-calorie foods compared to neutral objects. No significant results emerged as regards RT. The pattern of responses observed in patients with AN-R (deviation increased toward low-calorie and reduced toward high-calorie) is consistent with their eating habits and may thus represent an implicit mechanism sustaining calorie restriction in patients with AN-R., Competing Interests: Declaration of competing interest The authors have no conflict of interest to declare., (Copyright © 2023 Elsevier Ltd.

In recent years, different studies highlighted the importance of assessing behavioral tendencies toward different food stimuli in healthy and pathological samples. However, heterogeneities in experimental approaches and small sample sizes make this literature rather inconsistent. In this study, we used a mobile approach-avoidance task to investigate the behavioral tendencies toward healthy and unhealthy foods compared to neutral objects in a large community sample. The role of some contextual and stable subjective variables was also explored. The sample included 204 participants. The stimuli comprised 15 pictures of unhealthy foods, 15 pictures of healthy foods, and 15 pictures of neutral objects. Participants were required to approach or avoid stimuli by respectively pull or push the smartphone toward or away from themselves. Accuracy and reaction time of each movement were calculated. The analyses were conducted using a generalized linear mixed-effect model (GLMMs), testing the two-way interaction between the type of movement and the stimulus category and the three-way interactions between type of movement, stimulus, and specific variables (BMI, time passed since the last meal, level of perceived hunger). Our results evidenced faster approaching movement toward food stimuli but not toward neutrals. An effect of BMI was also documented: as the BMI increased, participants became slower in avoiding unhealthy compared to healthy foods, and in approaching healthy compared to unhealthy stimuli. Moreover, as hunger increased, participants became faster in approaching and slower in avoiding healthy compared to unhealthy stimuli. In conclusion, our results show an approach tendency toward food stimuli, independent from caloric content, in the general population. Furthermore, approach tendencies to healthy foods decreased with increasing BMI and increased with perceived hunger, indicating the possible influence of different mechanisms on eating-related behavioral tendencies., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Ltd.

Objective: Recent neuroscientific findings have highlighted the role of the thalamus in several cognitive functions, ranging from perception to cognitive flexibility, memory, and body representation. Since some of these functions may be involved in the pathophysiology of Anorexia Nervosa (AN), this study aims at exploring thalamic structure in different phases of the disorder., Method: The sample included 38 patients with acute AN, 20 patients who fully recovered from AN (recAN), and 38 healthy controls (HC), all female. All participants underwent high-resolution MRI. The volumes of the whole thalamus and 25 thalamic nuclei were extracted using an automated segmentation algorithm, and thalamic fractal dimension was estimated using the calcFD toolbox., Results: Patients with acute AN, compared to HC, displayed reduced thalamic volume and complexity both at the whole level and at the level of specific nuclei. In patients recAN, instead, alterations were observed only at the level of the right laterodorsal and central lateral nuclei., Conclusions: In the acute phase of the disorder patients with AN present a widespread reduction in thalamic volume and complexity. However, these alterations seem to normalise almost completely following weight restoration, thus suggesting the involvement of malnutrition-related mechanisms., (© 2022 Eating Disorders Association and John Wiley & Sons Ltd.)

The aim of this study was to explore, in a sample of patients with a diagnosis of AN, the ability to question their first impression and, in particular, the willingness to integrate their prior ideas and thoughts with additional progressive incoming information. A total of 45 healthy women and 103 patients with a diagnosis of AN, consecutively admitted to the Eating Disorder Padova Hospital-University Unit, underwent a broad clinical and neuropsychological assessment. All participants were administered the Bias Against Disconfirmatory Evidence (BADE) task, which specifically investigates belief integration cognitive bias. Acute AN patients showed a significantly greater bias toward disconfirming their previous judgment, in comparison to healthy women (BADE score, respectively, 2.5 ± 2.0 vs. 3.3 ± 1.6; Mann-Whitney test, p = 0.012). A binge-eating/purging subtype of AN individuals, compared to restrictive AN patients and controls, showed greater disconfirmatory bias and also a significant propensity to uncritically accept implausible interpretations (BADE score, respectively, 1.55 ± 1.6 and 2.70 ± 1.97 vs. 3.33 ± 1.63; Kruskal-Wallis test, p = 0.002 and liberal acceptance score, respectively, 1.32 ± 0.93 and 0.92 ± 1.21 vs. 0.98 ± 0.75; Kruskal-Wallis test p = 0.03). Abstract thinking skills and cognitive flexibility, as well as high central coherence, are neuropsychological aspects positively correlated with cognitive bias, in both patients and controls. Research into belief integration bias in AN population could enable us to shed light on hidden dimensional aspects, facilitating a better understanding of the psychopathology of a disorder that is so complex and difficult to treat.

(1) Background: the investigation of how interpersonal functioning affects eating psychopathology has been receiving increasing attention in the last decade. This study evaluates the impact of virtual social inclusion or ostracism on emotions, perceived stress, eating psychopathology, and the drive to binge or restrict in patients across the eating disorder spectrum. (2) Methods: a group of 122 adolescent and adult females with different eating disorder diagnoses were compared to 50 healthy peers with regards to their performance on, and responses to the Cyberball task, a virtual ball-tossing game. Each participant was randomly assigned to playing a social inclusion or a social exclusion block of the Cyberball task and completed self-report assessments of emotions, perceived stress and urge to restrict/binge before and after the task. (3) Results: patients with anorexia nervosa showed a more negative impact on psychological well-being evaluated with the need threat scale after the excluding block, while patients with bulimia nervosa reported more negative effects after the overincluding condition. Patients with binge eating disorder showed a reduction in specific negative emotions after the overincluding block, unlike all other participants. (4) Conclusions: findings show significant correlations between restraint thoughts in patients with bulimia nervosa and binge thoughts in patients with binge eating disorder after being exposed to the inclusion condition. Different reactions in cognitive and emotional states of patients with eating disorders after different interpersonal scenarios confirm the impact of inclusive or exclusive relationships on eating psychopathology, with specific and different responses across the eating disorder spectrum, that have been discussed, linked to their eating behavioral cognition.

Aim: Recent evidence suggests that the body image disturbance often observed in patients with anorexia nervosa also extends to the body schema. According to the embodiment approach, the body schema is not only involved in motor execution, but also in tasks that only require a mental simulation of a movement such as motor imagery, mental rotation of bodies, and visuospatial perspective-taking. The aim of the present study was to assess the ability of patients with anorexia to mentally simulate movements., Methods: The sample included 52 patients with acute anorexia and 62 healthy controls. All participants completed three tests of explicit motor imagery, a mental rotation test and a test of visuospatial perspective-taking., Results: Patients with anorexia nervosa, with respect to controls, reported greater difficulties in imagining movements according to a first-person perspective, lower accuracy in motor imagery, selective impairment in the mental rotation of human figures, and reduced ability in assuming a different egocentric visuospatial perspective., Conclusion: These results are indicative of a specific alteration in motor imagery in patients with anorexia nervosa. Interestingly, patients' difficulties appear to be limited to those tasks which specifically rely on the body schema, while patients and controls performed similarly in the 3D objects mental rotation task., (© 2022 The Authors.

Objective: Food-related anxiety and avoidance are key features of anorexia nervosa, and among the most arduous maintaining processes to address in treatment. This study gathered information on the behavioural and cognitive correlates of food-related anxiety, including their associations with early experiences of aversive learning related to food, and more general anxiety., Methods: One-hundred and forty-four patients with anorexia nervosa were recruited from clinical services in Italy. They completed online questionnaires to assess food-related anxiety, eating disorder psychopathology, eating disorder safety behaviours and threat cognitions, early experience of aversive learning related to food, and somatic anxiety., Results: Experiences of food-related aversive learning were recalled by the majority of the sample (87.86%), with negative psychological consequences following eating being the most often reported (75%). Safety behaviours and threat cognitions related to the consequences of eating were also reported (14.29%-87.86%, and 36.43-90% respectively, depending on the behaviour/cognition). Eating disorder psychopathology was predicted by both somatic anxiety and negative psychological consequences following eating, whereas self-reported food anxiety was only predicted by somatic anxiety., Conclusion: Findings validate an anxiety-based model of anorexia nervosa which establishes the role of safety behaviours, threat cognitions, early aversive learning experiences, and anxiety in the psychopathology of the illness. Exposure-based interventions have the potential to target these factors, and inhibit food-related fear., Competing Interests: Declaration of competing interest The authors have no conflict of interest to disclose., (Copyright © 2022 The Authors.

Purpose: The aim of this study was to expand the evidence on the feasibility and impact of food-specific inhibitory control training in a community sample of people with disinhibited eating., Methods: Recruitment and data collection were conducted during the COVID-19 outbreak, in Italy. Ninety-four adult individuals with disinhibited eating were randomised to one of two conditions: App-based food-specific inhibitory control training or waiting list. Participants were assessed at baseline, end of intervention (2 weeks following baseline) and follow-up (one week later). The assessment measures included questionnaires about eating behaviour and mood., Results: Seventy-three percent of the sample reported a diagnosis of binge eating disorder, and 20.4% a diagnosis of bulimia nervosa. Retention rates were 77% and 86% for the food-specific inhibitory control training and the waiting list conditions, respectively. Almost half of the participants allocated to the training condition completed the "recommended" dose of training (i.e., 10 or more sessions). Those in the training condition reported lower levels of wanting for high-energy dense foods (p < 0.05), a trend for lower levels of perceived hunger (p = 0.07), and lower levels of depression (p < 0.05). Binge eating symptoms, disinhibition, wanting for high-energy dense foods, stress and anxiety were significantly lower at end of intervention, compared to baseline (p < .05)., Conclusion: Findings corroborated the feasibility of food-specific inhibitory control training, and its impact on high-energy dense foods liking. The study expands the evidence base for food-specific inhibitory control training by highlighting its impact on perceived hunger and depression. The mechanisms underlying these effects remain to be clarified., Level of Evidence: Level I, Evidence obtained from at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies., (© 2022.

(1) Background: Weight bias (WB) is an implicit psychological construct that can influence attitudes, beliefs, body experience, and evaluation of specific psychopathology relationships. Sexual orientation has played a crucial role in developing and maintaining psychiatric conditions linked to body evaluation, but few studies have evaluated possible connected biases. Thus, the paper aims to assess potential relationships between sexual orientation and WB, looking at potential roles in specific psychopathology; (2) Methods: A total of 836 cisgender subjects participated in an online survey, aged between 18 and 42 years old. Two specific aspects of WB were evaluated with validated scales about beliefs about obese people and fat phobia. Demographic variables, as well as depression and eating concerns were evaluated; (3) Results: Gay men and bisexual women showed higher levels of fat phobia, depression, and eating concerns. Regression analysis showed that sexual orientation significantly predicted fat phobia (p < 0.001) and beliefs about obese people (p = 0.014); (4) Conclusions: This study confirms the vulnerability of gay men and bisexual women to cognitive bias about their own bodies, showing a potential vulnerability about body and weight concerns.

Fractal geometry has recently been proposed as a useful tool for characterizing the complexity of the brain cortex, which is likely to derive from the recurrence of sulci-gyri convolution patterns. The index used to describe the cortical complexity is called fractal dimensional (FD) and was employed by different research exploring the neurobiological correlates of distinct pathological and nonpathological conditions. This review aims to describe the literature on the application of this index, summarize the heterogeneities between studies and inform future research on this topic. Sixty-two studies were included in the systematic review. The main research lines concern neurodevelopment, aging and the neurobiology of specific psychiatric and neurological disorders. Overall, the included papers indicate that cortical complexity is likely to reduce during aging and in various pathological processes affecting the brain. Nevertheless, the high heterogeneity between studies strongly prevents the possibility of drawing conclusions. Further research considering this index besides other morphological values is needed to better clarify the role of FD in characterizing the cortical structure., (© 2022 The Authors.

Purpose: Recent evidence from neuroimaging research has shown that eating disorders (EDs) are characterized by alterations in interconnected neural systems, whose characteristics can be usefully described by connectomics tools. The present paper aimed to review the neuroimaging literature in EDs employing connectomic tools, and, specifically, graph theory analysis., Methods: A systematic review of the literature was conducted to identify studies employing graph theory analysis on patients with eating disorders published before the 22nd of June 2020., Results: Twelve studies were included in the systematic review. Ten of them address anorexia nervosa (AN) (AN = 199; acute AN = 85, weight recovered AN with acute diagnosis = 24; fully recovered AN = 90). The remaining two articles address patients with bulimia nervosa (BN) (BN = 48). Global and regional unbalance in segregation and integration properties were described in both disorders., Discussion: The literature concerning the use of connectomics tools in EDs evidenced the presence of alterations in the topological characteristics of brain networks at a global and at a regional level. Changes in local characteristics involve areas that have been demonstrated to be crucial in the neurobiology and pathophysiology of EDs. Regional imbalances in network properties seem to reflect on global patterns., Level of Evidence: Level I, systematic review., (© 2021. The Author(s).)

(1) Background: patients with Anorexia Nervosa (AN) are classified either as restrictive (ANr) or binge/purge (ANbp) according to the absence or presence of impulsive eating and compensatory behaviors. The aim of the present study was to assess the levels of impulsivity in both AN subtypes and to explore whether individual differences in impulsivity may be explained by differences in the presence of early maladaptive schemas. (2) Methods: the sample group included 122 patients with ANr, 112 patients with ANbp, and 131 healthy women (HW). All of these participants completed the UPPS-P scale for an assessment of impulsive behaviors and the Young Schema Questionnaire (YSQ-S3) for an assessment of early maladaptive schemas. (3) Results: the patients with ANbp displayed higher levels of impulsivity compared with the patients with ANr and HW. Patients with AN, especially the restrictive subtype, also reported higher levels of early maladaptive schemas than HW, and regression analyses revealed that specific maladaptive schemas partially explain the variability in impulsivity in both patients and HW. (4) Conclusions: it appears that maladaptive beliefs developed during childhood or adolescence may predict the development of impulsivity, a personality trait usually associated with maladaptive behaviors, and appears to be prevalent among ANbp patients. The clinical effects of this, as well as directions for future study, are also discussed in this paper.

Previous research evidenced alterations of different cortical parameters in patients with acute Anorexia Nervosa (AN), but no study to date investigated the morphology of individual sulci and their relationship with other structural indices. Our study aims at exploring the depth and width of 16 major cortical sulci in AN at different stages of the disorder and their relationships with the gyrification gradient. Two samples were included in the study. The first involved 38 patients with acute AN, 20 who fully recovered from AN, and 38 healthy women (HW); the second included 16 patients with AN and 16 HW. Sulcal width and depth were estimated for 16 sulci and outlined with a factorial analysis. An anterior-posterior gradient of gyrification was also extracted. Compared to HW, patients with acute AN displayed higher width and depth values in specific cortical sulci, and an altered gyrification gradient in areas encompassing the Central Sulcus, and Parieto-Temporal and Frontal Lobe regions. Sulcal width negatively correlated with gyrification gradient in areas where these values are altered in AN patients. Our results suggest the presence of alterations in sulcal morphology with a pattern similar to the gyrification gradient one and which seems to be related with malnutrition., (Copyright © 2021 Elsevier B.V.

Introduction: Anorexia nervosa is usually associated with emotional and cognitive difficulties. Little knowledge is available about the changes in cognitive functioning in patients undergoing treatments. The aim of the present study was to longitudinally assess the impact of partial hospitalization on clinical and cognitive functioning in anorexia nervosa. Materials and Methods: 56 women with anorexia nervosa according to DSM-5 criteria and 58 healthy women were enrolled in the study. At baseline, all participants underwent clinical, diagnostic and neuropsychological assessment (T0). Patients were also assessed at the end of the treatment program (T1; n = 56). Results: BMI improved significantly throughout treatment. At baseline, patients showed significantly poorer executive abilities and less specific autobiographical memory. After the day-hospital program, decision-making abilities improved significantly. Response to treatment was predicted by BMI at admission and duration of illness, but neuropsychological performance did not contribute to the prediction model. Discussion: Cognitive difficulties, mostly regarding executive functions, resulted differently affected by clinical improvement. In particular, while cognitive monitoring and cognitive inhibition appear to be mostly stable trait-like characteristics, decision-making is both more state-dependent and sensitive to clinical status. None of the cognitive variables added information about the response to day hospital treatment; patients with short duration of illness and a rapidly decreasing BMI would benefit more from intensive interventions than less "acute" patients. These observations, if confirmed by future studies, have important clinical implications in order to understand the impact of malnutrition on cognitive functioning and to provide individualized effective treatment for patients with anorexia nervosa., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Tenconi, Collantoni, Meregalli, Bonello, Zanetti, Veronese, Meneguzzo and Favaro.)

The COVID-19 pandemic is causing a heavy burden in hospital healthcare workers (HCW) in terms of increased work, organizational changes, risk exposure, and social stigma. The present study aims at evaluating the psychological outcome among HCWs at the final stages of the first wave of the COVID-19 pandemic. This cross-sectional and survey-based study was conducted during June 2020 among 996 HCWs of the University Hospital of Padova. All the subjects completed questionnaires investigating the perception of risk of infecting or being infected by COVID-19, psychopathological variables, and coping abilities. Compared to physicians and healthcare assistants, nurses showed higher levels of depression ( p = 0.002), insomnia ( p < 0.001), and generalized anxiety ( p = 0.001). Females reported increased concerns about the possibility of infecting others ( p = 0.046), greater anxiety ( p < 0.001), COVID-19 related fears ( p < 0.001), depression ( p < 0.001), and post-traumatic distress ( p < 0.001) than males. Being employed in a COVID-19 unit, being transferred to other units, and living with children and the elderly were factors associated with higher levels of psychological distress. Greater coping abilities were detected in physicians, and in those HCWs employed in COVID units. Our findings evidenced that the psychological consequences of the pandemic were non-homogeneously distributed across HCWs categories and pointed out the presence of specific in-hospital and out-of-hospital risk factors.

No study to date investigated structural white matter (WM) connectome characteristics in patients with anorexia nervosa (AN). Previous research in AN found evidence of imbalances in global and regional connectomic brain architecture and highlighted a role of malnutrition in determining structural brain changes. The aim of our study was to explore the characteristics of the WM network architecture in a sample of patients with AN. Thirty-six patients with AN and 36 healthy women underwent magnetic resonance imaging to obtain a high-resolution three-dimensional T1-weighted anatomical image and a diffusion tensor imaging scan. Probabilistic tractography data were extracted and analyzed in their network properties through graph theory tools. In comparison to healthy women, patients with AN showed lower global network segregation (normalized clustering: p = 0.029), an imbalance between global network integration and segregation (i.e., lower small-worldness: p = 0.031), and the loss of some of the most integrative and influential hubs. Both clustering and small-worldness correlated with the lowest lifetime body mass index. A significant relationship was found between the average regional loss of cortical volume and changes in network properties of brain nodes: the more the difference in the cortical volume of brain areas, the more the increase in the centrality of corresponding nodes in the whole brain, and the decrease in clustering and efficiency of the nodes of parietal cortex. Our findings showed an unbalanced connectome wiring in AN patients, which seems to be influenced by malnutrition and loss of cortical volume. The role of this rearrangement in the maintenance and prognosis of AN and its reversibility with clinical improvement needs to be established by future studies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Collantoni, Meneguzzo, Tenconi, Meregalli, Manara and Favaro.)

Aim: How long the waiting time may be for the onset of spontaneous labor after prelabor rupture of fetal membranes at term (tPROM) remains controversial., Methods: The study is an observational cohort study of 6032 women. All obstetric patients with no obstetric risk factors, other than tPROM, were included. The analysis focused on the onset of labor (spontaneous vs. induction), maternal morbidity [cesarean section (CS) and chorioamnionitis] and neonatal morbidity (suspected infection) related to a policy of waiting for the onset of spontaneous labor within 48 h of tPROM., Results: tPROM was experienced by 1439 women. A careful clinical management shows a very low rate of clinical chorioamnionitis (2.3%) and neonatal infection rate (2.8%), even after 24 h from tPROM. The overall incidence of CS was 4.5%. Furthermore, a policy of waiting for the onset of spontaneous labor within 48 h of tPROM is associated with a low rate of CS, less than induced labor (OR=1.76; 95% confidence interval 1.03-3.02; P<0.004)., Conclusions: Fetal and/or maternal morbidity in tPROM women may not increase if there is a strict analysis of maternal and or fetal risk factors added to a careful clinical management. Moreover, it may be useful to wait for spontaneous labor in order to enhance the patient's chance of vaginal delivery.

Background: Dinoprostone vaginal insert has been compared to Dinoprostone cervical gel in few studies, whose cases presented different Bishop scores and gestational ages at admission, and various treatment strategies in control arms. The present study compares the vaginal insert to the cervical gel in patients with low Bishop score at term., Methods: Prospective multicenter randomized trial, with parity-based randomization. Admission criteria: single pregnancy with Bishop score of 0-4, gestational age of 37-41 weeks, intact membranes, no previous cesarean section, no bleeding or abnormal cardiotocography at admission., Results: Vaginal prostaglandins were required as a second-line induction procedure in 25% of study patients versus 47.1% of controls (p < 0.03, chi2). Study patients experienced shorter induction-to-delivery time (920 +/- 428 versus 1,266 +/- 740 min, p <0,01), with a mean difference of 5 h and 46 min between the groups. Even though patients that received vaginal insert showed a trend of increased incidence of abnormal cardiotocography during labor (12% versus 6.3%) and hyperkinetic labor (11.8% versus 2.1%), the incidence of cesarean sections (21.4% versus 21.6%), cesareans for fetal distress (12.5% versus 11.8%), and umbilical artery pH <7.10 (4.9% versus 2.5%) was comparable between the two groups., Conclusions: Dinoprostone vaginal insert is more efficient than cervical gel in promoting cervical priming and labor induction in low-Bishop-score patients at term. The vaginal insert placement seems to be safe for the mother and the newborn, although larger studies are required to investigate uterine hyperstimulation incidence.

The authors report the case, non forming part of any known syndrome, of a newborn with encephalocele, high cranial schisis, ocular anomalies, cleft palate and congenital clubfoot. The photographic documentation of the malformations is not possible due to a technical error in taking the photographs (lack of light in the room). Alterations to cerebral nervous tissue were histologically and cytologically characterised by immaturity and block of normal development during the early stages. For this reason the alteration of primary neuro-ectodermal tissue appears to be the initial factor with secondary involvement of anatomically and functionally contiguous fields and tissues, such as cranial bones and the eyes. The alteration of the nervous system resulted in the incapacity of the fetus to make fetal movements, making it vulnerable to extrinsic compression, above all uterine pressure. This led to the adoption of fixed postures with articular blockage most evident in the lower limbs (congenital clubfoot). The pathogenic noxa was not identified.
