RESUMO
BACKGROUND: Alexithymia is a multifaceted personality construct described as "a lack of words to express emotions" that includes difficulty identifying feelings, difficulty describing feelings and a concrete, externally oriented cognitive style. Among patients with food allergy (FA) alexithymia has been found higher than in general population and associated with dysfunctional coping strategies. Childhood traumatic experiences and/or dysfunctional parent-child relationship can contribute to alexithymia. The study aimed to explore possible associations between child alexithymia and mother alexithymia and anxiety, as well as previous anaphylaxis. METHODS: Sixty-five mother-child pairs have been recruited. Children had a medical diagnosis of FA. The Toronto Alexithymia Scale-20 was used to assess alexithymia in participants. The State-Trait Anxiety Inventory was used to assess trait anxiety in mothers. Statistical analysis was performed to investigate the influence of variables sex, previous anaphylaxis, and adrenaline auto-injector prescription on child and mother's alexithymia and to explore possible association between maternal and child alexithymia. RESULTS: A substantial percentage of children were alexithymic (21.5%) or borderline (33.8%), while mothers' frequencies were lower and in line with prevalence in general population. Child alexithymia was positively associated with previous anaphylaxis and mothers' trait anxiety (p < .05). Mother trait anxiety was also associated with maternal alexithymia. Furthermore, a positive association between child and mother alexithymia has been found. CONCLUSIONS: Clinicians must be aware of the role of alexithymia and its association with maternal anxiety and previous anaphylaxis in children with FA, encouraging seeking psychological support when needed. A multidisciplinary patient-centered approach should be put in place for the effective care of FA.

Food allergy (FA) is recognized as a growing public health burden affecting 5%-10% of children worldwide. Several unique features specific to FA elicit high levels of emotional distress and anxiety in patients and caregivers, the first among all the possibility of a life-threatening reaction. Anxiety disorders are highly prevalent in patients with chronic disease, but remain undertreated despite significant negative consequences on patient health. This review aimed to offer a comprehensive overview of literature data on FA and anxiety of the last two decades. A review of the medical and psychological literature from the year 2000 (MEDLINE, PubMed and PsycINFO) was done using the keywords "anxiety" and "food allergy." Clinical implications for disease management, various manifestations in different target groups, proper interventions and possible explanations on the nature of the association between FA and anxiety have been discussed, as well as limitations and further research directions. The relationship between FA and anxiety is attributed to FA-specific fears and anxiety, rather than a general propensity towards anxiety. Some anxiety-short-lived and related to key events-is to be expected and may even be helpful if it sustains allergen avoidance and preparedness to emergency. However, some data reported that increased anxiety did not improve adherence. Rather, high levels of anxiety have been demonstrated counterproductive and related to maladaptive coping. Further research is needed to elucidate the association between FA and anxiety, especially to understand biopsychosocial directions of the underlying mechanisms and to build proper, effective, standardized protocols of intervention. Clinicians must be aware of the association between FA and anxiety, understand their role in recognizing maladaptive anxiety and encouraging to seek psychological support when needed.

BACKGROUND: Despite a relatively high risk for allergic reactions, including anaphylaxis, schools are not sufficiently trained and confident in handling children suffering from food allergy. This study aimed to measure the improvement of school personnel's self-efficacy in managing food allergy and anaphylaxis at school after a specific multidisciplinary training course. METHODS: A total of 592 teachers and school caretakers completed the School Personnel Self-Efficacy-Food Allergy and Anaphylaxis Questionnaire (S.PER.SE-FAAQ) before and after the course. The median difference, along with I quartile and III quartile, in scores between baseline and post-intervention assessment was calculated. A conditional regression tree was fitted for each outcome measured after the educational intervention. RESULTS: At baseline, school personnel reported low self-efficacy in anaphylaxis management (AM), especially in recognizing anaphylaxis symptoms and administering proper drugs. After the specific multidisciplinary training course, all scores improved. AM scores particularly showed a significant increase. School personnel's post-training self-efficacy was found to be related to initial levels. Some indicative threshold values emerged. Remarkably, participants with a low self-efficacy at baseline seemed to particularly benefit from the training. CONCLUSIONS: Results highlighted the effectiveness of specific multidisciplinary training courses in improving teachers' and school caretakers' self-efficacy in managing food allergy and anaphylaxis. The S.PER.SE-FAAQ is confirmed to be an easy and helpful tool to assess the level of food allergy and anaphylaxis management in the school staff and training effectiveness.

BACKGROUND: Food allergy is a common immunologic disease that includes potentially fatal reactions. It impacts considerably on patients' social life including close interpersonal relationships. Attachment theory provides a theoretic framework to evaluate the quality of close interpersonal relationships in chronic disorders. Attachment insecurity, mainly characterized by attachment avoidance, has been found in a variety of health conditions, but still needs to be investigated in food allergy. The study aimed to investigate attachment, as attitude to close interpersonal relationships, among food-allergic young patients, compared to healthy controls. METHODS: This is a cross-sectional study involving patients suffering from IgE-mediated food allergy sequentially recruited and matched to healthy controls for age and gender. The Attachment Style Questionnaire (ASQ) was used to assess five factors and two attachment dimensions (Anxiety-Avoidance). Associations with anaphylaxis and adrenaline prescription were explored among patients. RESULTS: 174 participants were assessed (female=45%; mean age=17.51; SD=4.26). Food-allergic patients reported significantly higher levels of Discomfort with Closeness (P<.05), Relationships as Secondary (P<.05) and Attachment Avoidance (P<.0001) compared to controls. CONCLUSIONS: Clinicians should be aware of implications of insecure attachment for health and illness. They should support patients in limiting social impairment finding a balance between safety and psychologic well-being.

Two-dimensional materials, such as graphene and MoS2, are films of a few atomic layers in thickness with strong in-plane bonds and weak interactions between the layers. The in-plane elasticity has been widely studied in bending experiments where a suspended film is deformed substantially; however, little is known about the films' elastic modulus perpendicular to the planes, as the measurement of the out-of-plane elasticity of supported 2D films requires indentation depths smaller than the films' interlayer distance. Here, we report on sub-ångström-resolution indentation measurements of the perpendicular-to-the-plane elasticity of 2D materials. Our indentation data, combined with semi-analytical models and density functional theory, are then used to study the perpendicular elasticity of few-layer-thick graphene and graphene oxide films. We find that the perpendicular Young's modulus of graphene oxide films reaches a maximum when one complete water layer is intercalated between the graphitic planes. This non-destructive methodology can map interlayer coupling and intercalation in 2D films.
RESUMO
BACKGROUND: Food allergy affects up to 4-7% European schoolchildren. Studies identified important shortcomings on food allergy and anaphylaxis management in schools. In social cognitive theory, personal beliefs in own capabilities influence choices, effort levels, perseverance and performance accomplishments. This study aimed to investigate school personnel's self-efficacy in managing food allergy and anaphylaxis, providing a valid instrument to deeply understand how to support schools to effectively manage students at risk of food reactions. METHODS: A total of 440 schoolteachers and caretakers from north-east Italy completed a questionnaire assessing self-efficacy in managing food allergy and anaphylaxis at school. Exploratory factor analysis was performed. Factors' internal consistency was evaluated using Cronbach's alpha. Factors' scores were estimated using Bartlett approach, and kernel density estimate of distributions was provided. Descriptive statistics explored school personnel's self-efficacy. A regression model assessed the influence of gender, school, job and previous experience. RESULTS: Two factors emerged from exploratory factor analysis related to anaphylaxis management (AM) and food allergy management (FAM). The two subscales both showed good internal consistency. School personnel showed lower self-efficacy in recognizing symptoms, administering drugs and guaranteeing full participation to extra-curricular activities to food-allergic students. Participants who previously had food-allergic students showed a significantly increased self-efficacy in AM and a significantly decreased self-efficacy in FAM. CONCLUSIONS: The study supports the use of self-efficacy scale to identify specific areas where teachers' confidence in their ability to care for food-allergic students is especially weak. This would empower the development of training programs specifically tailored to the needs of teachers and caregivers.

The fundamental building blocks of digital electronics are logic gates which must be capable of cascading such that more complex logic functions can be realized. Here we demonstrate integrated graphene complementary inverters which operate with the same input and output voltage logic levels, thus allowing cascading. We obtain signal matching under ambient conditions with inverters fabricated from wafer-scale graphene grown by chemical vapor deposition (CVD). Monolayer graphene was incorporated in self-aligned field-effect transistors in which the top gate overlaps with the source and drain contacts. This results in full-channel gating and leads to the highest low-frequency voltage gain reported so far in top-gated CVD graphene devices operating in air ambient, A(v) â¼ -5. Such gain enabled logic inverters with the same voltage swing of 0.56 V at their input and output. Graphene inverters could find their way in realistic applications where high-speed operation is desired but power dissipation is not a concern, similar to emitter-coupled logic.
RESUMO
BACKGROUND: Oral immunotherapy (OIT) is a promising treatment for food allergy (FA) however it is a challenging process for patients and parents. Induction can generate stress and anxiety. This may in turn affect their motivation and ability to cope with OIT challenges. OBJECTIVE: This study aimed to investigate psychological needs and support to patients/parents undergoing food OIT assessing participants' main characteristics, reasons for seeking psychological support, OIT phase and related psychological difficulties, type and timing of treatments and patients' perception of the effectiveness of the intervention. METHODS: This is an observational, retrospective study. 50 psychological interventions required for OIT related problems were selected consecutively in a Referral Centre in North-Eastern Italy. All patients had a medical diagnosis of FA and were undergoing OIT or had just discontinued it. Data were collected from hospital records. A descriptive statistical analysis was performed. RESULTS: 66% of patients asked for psychological support for the initial phase (e.g., oral food challenge, first maintenance doses), 20% during the up-dosing phase, 8% during maintenance and 6% after discontinuation. 70% of treatments were required mainly because of emotional problems including dysfunctional anxiety and mood disorders, increased distress and excessive worry and/or fear related to OIT; 20% because of difficulties in managing OIT; 10% because of eating difficulties; 50% of patients reported recent anaphylaxis. All patients reported improvement and felt the psychological intervention was helpful. CONCLUSION: It is recommended to evaluate the psychological needs in profiling patients and families suitable to OIT and offer specific psychological support when needed.
RESUMO
Background: Anaphylaxis is a life-threatening event, but it is frequently undertreated in pediatric patients with food allergies. Previous studies showed that auto-injectable adrenaline (AAI) is underused by patients and parents. This is especially troubling since fatal anaphylaxis has been associated with delayed adrenaline administration. Objectives: This study aimed to investigate parental practice and knowledge in anaphylaxis management, and perceived barriers and facilitators in using AAI. Results: A retrospective survey was completed by 75 parents (41 mothers, 34 fathers) of children with food allergy and AAI prescription attending the Food Allergy Referral Center of Veneto, Italy. Results showed poor parental preparedness and reluctance to use AAI despite a high/moderate self-rated knowledge (median total score of 23-min. 3, max. 30). Most parents (77%) declared they were carrying AAI but only 20% used it in case of a severe reaction. Most reported Fear/Fear of making mistakes (46 parents) and Concern about possible side effects as barriers (35), while Poor knowledge of the correct AAI use (1) and Lack of knowledge/ incorrect assessment of symptoms (2) were reported less frequently. Theoretical-practical courses for parents on AAI use (65), Psycho-education/Psychological support (3) for better dealing with the emotional aspects of anaphylaxis and Written instructions (1) have been suggested as main facilitators. Conclusion: Understanding parents' experience and perspective on managing anaphylaxis is crucial to implement effective educational programs. A multidisciplinary approach should be considered.
RESUMO
The current SARS-CoV-2 disease (COVID-19) pandemic is a sudden major stressor superimposed on pre-existing high distress in parents of infants admitted to the neonatal intensive care unit (NICU). This study aimed to investigate the psychological wellbeing of NICU parents during the COVID-19 pandemic. Forty-four parents of 25 inpatients of the Padua University Hospital NICU were included from June 2020 to February 2021. At 7-14 days postpartum parents completed the Edinburgh Postnatal Depression Scale (EPDS), State-Trait Anxiety Inventory (STAI), Parental Stressor Scale: NICU (PSS:NICU) and an ad-hoc questionnaire measuring parental COVID-19 related stress. About one third of parents reported extreme/high stress and a relevant negative impact on parenthood experience. Less time (82%) and less physical contact (73%) with infants due to COVID-19 preventive measures were the most frequent negative factors. Higher COVID-19 related parental stress was positively associated with anxiety, depression, NICU parental stress, stress related to NICU environment, and parental role alterations. Depression symptoms, stress related to infant condition and parental role alterations were higher in mothers. The pandemic affected parental emotional and relational wellbeing directly through additional stress due to COVID-19 concerns and indirectly through the impact of restrictions on the experience of becoming parents.

BACKGROUND: We have previously developed a food allergy-specific developmental model, that explained emotions and coping styles, among children aged 6 to 15years in Ireland. OBJECTIVE: The objective of this study was to investigate the usefulness of the developmental model in a large multicountry data set, including any mediators of coping style, and to use the findings to generate an item pool that will form the basis for 3 age-appropriate self-report questionnaires to measure coping and emotions. METHODS: We conducted deductive thematic analysis on secondary data from interviews with 274 participants aged 6 to 23 years, and 119 parents from Australia, Ireland, Italy, the UK, and the USA. Analysis was undertaken across the entire data set. RESULTS: The Food Allergy Coping and Emotions (FACE) model has 5 major themes: (1) experiences and emotions, (2) search for normality, (3) management and coping, (4) "external mediators," and (5) "internal mediators" (between emotions and coping). These themes were present across countries, but differed according to age. CONCLUSIONS: Early-life experiences provide the foundation for later cognitions and behaviors. The expanded FACE developmental model is useful in explaining emotions and coping styles across different age groups and countries. These data will also be used to generate an age-specific bank of items for the development of 3 (age-specific self-report, and parent proxy) questionnaires to assess emotions and coping in food allergy. Findings provide insight into how particular styles of coping develop and vary from patient to patient and may also guide clinician-patient communication and the development of individualized management strategies.

Alexithymia is a multifaceted personality construct associated with several medical illnesses. However, no studies have focused on food allergy. We investigated alexithymia among food-allergic youths, compared to a matched healthy sample. A total of 220 participants aged 9-25 years were assessed using the Toronto Alexithymia Scale and the Alexithymia Questionnaire for Children. Food-allergic patients reported higher levels of alexithymia compared to a matched healthy sample. Furthermore, an association between alexithymia and a clinical history of anaphylaxis was found among patients. Some possible hypotheses have been discussed considering physiological, psychological, developmental, and cognitive/behavioral factors.
