The role of family relationships in eating disorders in adolescents: a narrative review

Abstract: Background: Adolescents’eatingdisordershavebeenexploredthroughvariousconceptual andempiricalmodels. Onlyrecently,scientificliteratureinthisareahasmorespecificallyinvestigated theroleofrelationships,withparticularattentiontofamilyfunctioning. Objective: Thispaperreviews family relationships aspects of eating disorders in adolescence. Methods: A narrative literature review of relational issues in adolescents’ eating disorders was performed. Results: Empirical evidence of family relationships in adolescents’ eating disorders confirms the relevance of relational aspects in the development and maintenance of the pathology. In particular, the contribution of the relational-systemic approach is wide, suggesting the need to refer to the family context for a better understanding of adolescents’ sufferance. Additionally, the empirical contributions from the conceptual model of Developmental Psychopathology, highlighting the importance of risk and protection factors in family relationships, provides knowledge about the phenomenon of adolescents’ eating disorders in terms of complexity. Conclusions: An integrated relational model aimed to explore adolescents’ eating disorders is worthy of investigation to accomplish specific program of intervention

Direct measurement of ultrasonic activity on microbial metabolism and analysis of related uncertainty

The scope of this work is to identify the relation that exists between the alterations of the bacterial metabolism and the exposition to an ultrasonic field (O'Leary et al. 1997, Piyasena et al. 2003, Brujan2004). To made this relation quantifiable they will be used repeatable and reproducible metrological methods. To obtain this result the research will be centred on 3 specific goal: 1. To realise a measurement of the ultrasonic field, generated by an ultrasonic bath, using an hydrophone calibrated specifically with the wavelengths applied (Canney et al. 2008). 2. To choose a method, through uncertainty evaluation, to expose microbes to the ultrasonic field without an excessive alteration of the generated acoustic pressure. 3. To find a method to measure bacterial viability, represented by the planktonic growth and the biofilm development, after exposure to the ultrasounds. Studying the relationship between the bacteria metabolism and ultrasonic exposure it will be possible to identify novels and more precise methods to treat bacterial colonizations. This result will be in fact useful in various fields where the bacterial presence, and in particular biofilm development, is today an unresolved problem. At the same time this research will put the basis for many further studies that will be realized applying the same methods with different bacterial species, ultrasounds exposition conditions or ultrasonic devices

Psychopathological risk in parentally bereaved adolescents

For a child, the death of a parent is a traumatic experience and can give rise to several difficulties during the child’s development. International literature in this field has focused on clinical populations; evaluations of the psychological difficulties in adulthood have rarely been aimed at non-referred samples. The present study assessed the psychological functioning of a non-referred sample of adolescents, with consideration given to the impact of the loss of a caregiver during childhood on their psychological profiles. It also evaluated the association between the adolescents’ psychological profiles and possible psychopathological risk in the surviving parents. Three groups of subjects (N=96) were considered: adolescents who had suffered the loss before 3 years of age (Group A); adolescents who had experienced loss between 3 and 10 years of age (Group B); and adolescents who had experienced no loss (Group C). Psychological profiles, eating difficulties, and dissociative symptoms were evaluated during adolescence (14-16 years of age). Also assessed were the psychological profiles of the surviving caregivers. Group A had higher scores than Group B and C, indicating that there had not been an improvement in their psychological well-being. In addition, it was found that the psychological profiles of the surviving caregivers may have had an influence on the adolescents’ psychological difficulties. This result is important for prevention, and it could direct clinical work and early intervention in this specific field by taking into account the influence of the surviving parent

Adolescents’ psychological functioning and unintentional injuries: motor vehicles and sports accidents

Adolescence represents a crucial period for psychological development. Adolescents have been shown more prone to injuries than adults have and they are frequently involved in motor vehicle and sports accident. Although adolescents’ injuries have been widely investigated in international literature, victims’ psychological profiles associated with different types of accidents have been scarcely addressed. The present study aimed to identify adolescents’ psychological functioning associated with different types of injuries among a population of Italian adolescents who visited an emergency department. Moreover, the present paper intended to compare psychological profiles of adolescents who have had road and sports accidents. The sample was composed by N= 60 adolescents who attended an emergency department in central Italy. Subjects completed self-report measures assessing emotional and behavioural functioning and the use of defence mechanisms. Both road and sport accidents were associated with adolescents’ maladaptive psychological functioning. Adolescents involved in motor vehicle accidents showed a problematic emotional and behavioural functioning in general and a massive use of defense strategies; their peers who had sport accidents also show various difficulties in internalizing and externalizing functioning. Several adolescents’ emotional-behavioural variables are associated with injuries rates. Risk taking behaviours and other victims’ psychological profiles should be considered to have an exhaustive picture of individual factors that can impair a healthy development

Developmental trajectories of body mass index and emotional-behavioral functioning of underweight children. A longitudinal study

Although several studies have addressed developmental trajectories from childhood to adolescence of internalizing/externalizing problems, limited attention has been given to underweight children. Two groups were recruited for this study from a community sample: underweight (Ug, N = 80, 50% female) and normal weight (NWg, N = 80, 50% female) to examine the developmental trajectories of body mass index and emotional-behavioral functioning of underweight children from the age two years, and their risk of eating disorder at early adolescence. The study was organized over four waves, each of three years. Pediatricians measured BMI, parents completed the Child Behavior Checklist (CBCL) and the Eating Disorders Inventory-Referral Form (EDI-3-RF). Our results showed that children in the two groups recorded different BMI trajectories over time. In NWg, male and female subjects started from a higher BMI at T1 than their peers. In Ug, internalizing and externalizing problems in males and females remained higher than their peers at all points of assessment. Males and females in Ug scored higher than those in NWg on EDI-3-RF total score. Our results indicate a need for effective physical and psychological assessment of underweight children in community samples to prevent psychological difficulties and eating disorders in adolescenc

Trajectories of aggressive and depressive symptoms in male and female overweight children. Do they share a common path or do they follow different routes?

The prevalence of childhood overweight is a major social and public health issue, and primary assessment should focus on early and middle childhood, because weight gain in these phases constitutes a strong predictor of subsequent negative outcomes. Studies on community samples have shown that growth curves may follow linear or non-linear trajectories from early to middle childhood, and can differ based on sex. Overweight children may exhibit a combination of physiological and psychosocial issues, and several studies have demonstrated an association between overweight and internalizing/externalizing behavior. Nevertheless, there is a dearth of longitudinal studies on depressive and aggressive symptoms in children with high BMI. This study adopted a growth curve modeling over three phases to: (1) describe BMI trajectories in two groups of children aged 2–8 (overweight and normal weight) from a community sample; (2) describe the developmental trajectories of children’s aggressive and depressive symptoms from 2 to 8 years of age. Results indicate higher BMI in 2-year-old girls, with males catching up with them by age 8. While overweight females’ BMIs were consistently high, males’ increased at 5 and 8 years. The mean scores for aggressive symptoms at T1 (2 years of age) were the same in all subjects, but a significant deviation occurred from T1 to T2 in both samples, in divergent directions. With regards to children’s depressive symptoms, the two groups had different starting points, with normal weight children scoring lower than overweight youths. Overweight females showed lower depressive scores than overweight males at T1, but they surpassed boys before T2, and showed more maladaptive symptoms at T3. This study solicits professionals working in pediatric settings to consider overweight children’s psychopathological risk, and to be aware that even when children’s BMI does not increase from 2 to 8 years, their psychopathological symptoms may grow in intensit

Does alexithymia have a mediating effect between impulsivity and emotional-behavioral functioning in adolescents with binge eating disorder?

Objective: Binge eating Disorder (BeD) has recently been included in the Dsm-5. like many other eating disorder symptoms, BED is often present in adolescence. No studies have specifically investigated the influence of impulsivity and alexithymia on the emotional-behavioural functioning of adolescents diagnosed with BeD. Method: in this study, we recruited n = 162 adolescents (age range: 14-18) and divided them into two groups: 78 adolescents diagnosed with BeD, according to the Dsm-5 criteria (group A), and 84 healthy controls (group B). participants completed the youth self-report (ysr/11-18), the toronto Alexithymia scale (tAs-20) and the Barratt impulsiveness scale (Bis-11). Results: the results showed that group A had higher scores of alexithymia, impulsivity and maladaptive emotionalbehavioural functioning than Group B. Furthermore, alexithymia had a mediating effect on the relationship between impulsivity and emotional-behavioural functioning. Conclusions: These results allow us to hypothesise that alexithymia is a key variable influencing the emotional and behavioural problems of adolescents affected by BED. Our data confirms the previous studies underlining the association of impulsivity and alexithymia with the diagnosis of BeD in adolescents, and our study contributes to the previous literature, emphasising the central role of alexithymia in the mediating effect between impulsivity and emotional and behavioural problems. these results suggest the importance of promoting prevention and treatment polices focused on alexithymia

Il viceré Des Hayes e il governo del Regnum Sardiniae

The research aspires to realize the first monographic study of political and administrative activity of the Earl Vittorio Lodovico d’Hallot Des Hayes, Viceroy of Savoy in Sardinia from 1767 to 1771. This was the crucial moment in the policy of reformation for the Island, starting with Gian Battista Lorenzo Bogino, the Minister for Sardinian Affairs (1759-1773), intent upon increasing bureaucracy on the Island and realizing an administrative centralization. Reconstructing the political activity of Des Hayes allows the controversial studies of this reform politics of the Savoy household to be revised. This required new investigation of the documents regarding these years, correspondence, reports and essays, to realize an efficient wider framework. Des Hayes participated in debates in Cagliari and Turin about reform projects for the Island, disclosing their real efficiency, the modality of their application, and also class involvement, namely nobility and clergy (diocesan and regular) and their feelings about this. First of all, analysis of discussions within the councils reveals that Cagliari was less marginal than what has often considered by historians: Sardinian bureaucrats took an active part in these open discussions, suggesting many concrete and solid state interventions to face political, administrative, economic, feudal, ecclesiastical and cultural problems. Secondly, it results that the viceroy pursued a clear intent of reformation, but with extreme prudence. He found it essential to reconstitute warily, not upset drastically. Therefore, his approach was pragmatic: every reform had to be based on field work, the only way to remove preconceptions and to avoid intervention resulting from rash determination. For this reason, Des Hayes seem to be viceroy who had political freedom, supporting or declining the proposals developed in Cagliari and in Turin after an accurate analysis of their feasibility
