Emotional dysregulation and linguistic patterns as a defining feature of patients in the acute phase of anorexia nervosa.

PURPOSE: This research aims to analyze the relationship between emotional regulation and the symbolic process in autobiographical narratives of a group of individuals diagnosed with restrictive anorexia nervosa (AN), compared to a non-clinical group. The study is framed within multiple code theory (MCT) (Bucci, 1997; 2021), which considers mind-body integration. The purposes of this study are to investigate whether participants of the AN group will show greater alexithymia and emotional dysregulation than the non-clinical group; and whether the specific linguistic and symbolic features, such as somato-sensory words, affect words, and difficulty in the symbolizing process will predict the AN group. METHODS: Twenty-nine female participants hospitalized with AN during an acute phase (mean age 19.8 ± 4.1) and 36 non-clinical female participants (mean age 21 ± 2.4) were selected through snow-ball sampling. The participants completed the Toronto Alexithymia Scale (TAS-20), the Profile of Mood of State (POMS), the Emotion Regulation Questionnaire (ERQ), and the Relationship Anecdotes Paradigm Interview (RAP). The RAP interview was audio-recorded and transcribed to apply the Referential Process (RP) Linguistic Measures. A T test for paired samples and a logistic binary regression was performed. RESULTS: AN presented a significantly higher emotional dysregulation through the ERQ, TAS20 and POMS measures. Specifically, AN showed higher ER expression/suppression strategies, fewer functional cognitive strategies, higher alexithymia, and higher mood dysregulation. Specific linguistic features such as sensory-somatic, word affect, and difficulty in RP symbolizing predict the AN group (R2 = 0.349; χ2 = 27,929; df = 3; p = .001). CONCLUSIONS: Emotional dysregulation is connected to AN symptoms and autobiographical narratives. The results can help a clinical assessment phase showing specific linguistic features in AN patients. LEVEL OF EVIDENCE: Level II, controlled trial without randomization.

Magnetic Resonance Imaging Studies of Postpartum Depression: An Overview.

Postpartum depression is a frequent and disabling condition whose pathophysiology is still unclear. In recent years, the study of the neural correlates of mental disorders has been increasingly approached using magnetic resonance techniques. In this review we synthesize the results from studies on postpartum depression in the context of structural, functional, and spectroscopic magnetic resonance studies of major depression as a whole. Compared to the relative wealth of data available for major depression, magnetic resonance studies of postpartum depression are limited in number and design. A systematic literature search yielded only eleven studies conducted on about one hundred mothers with postpartum depression overall. Brain magnetic resonance findings in postpartum depression appear to replicate those obtained in major depression, with minor deviations that are not sufficient to delineate a distinct neurobiological profile for this condition, due to the small samples used and the lack of direct comparisons with subjects with major depression. However, it seems reasonable to expect that studies conducted in larger populations, and using a larger variety of brain magnetic resonance techniques than has been done so far, might allow for the identification of neuroimaging signatures for postpartum depression.

[Early attachement relationships and epigenetic customization]. / La regolazione epigenetica della relazione primaria.

Recently, new findings in epigenetic science switched the focus from the observation of physiological intragenomic dynamics to the idea of an environmental co-construction of phenotypic expression. In psichodynamic field, objectual relations and attachement theoreticians emphasized the interpersonal dimension of individual development, focusing the attention on the relational matrix of self organization. The construction of stable affective-behavioral traits throughout different parenting styles has actually found a coincidence in ethological studies, which have explored the epigenetic processes underlying the relationship between caregiving and HPA stress responsiveness. An adequate parenting style seems to support affective regulation throughout psychobiological hidden moderators, which would tend to rebalance the physiological systems homeostasis; an unconfident attachment style would promote, on the other hand, the allostatic load rise. Sites of longlife epigenetic susceptibility have also been identified in humans; although associated with risk of maladaptive developing in adverse environmental conditions, they seem to confer protection under favorable conditions. This persisting possibility of reorganization of stable traits throughout lifetime, which seems to be activated by a relevant environmental input, grant to significant relationships, and to therapeutical one as well, an implicit reconditioning potential which could result into the configuration of new stable affective-behavioral styles.

[Perinatal depression and affective bonds: experience in close relationship during pregnancy]. / Depressione perinatale e relazioni affettive: l'experience in close relationship in gravidanza.

AIM: This study aims to investigate the influence of the "romantic attachment" style, stressful life events, social factors on the risk of developing a depression during pregnancy and on the severity of depressive symptoms. METHODS: The study started with a screening on a sample of 453 women, during their third trimester of pregnancy, to which has been administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Experience in Close Relationship (ECR). Based on the results at EPDS, a clinical group of pre-natal depression (D=89) was selected and compared with a control group (C=89), in regards to psychopathological and social variables, exposure to stressful life events and attachment patterns. Analysis of correlation were performed to evaluate the influence of these factors on depressive symptoms severity. RESULTS: In D group, 52.8% of subjects reported previous psychiatric disorders and 49.4% a familiarity; 29.2% of these women complains of conflicts with their family of origin and 32.6% with partner. The ECR showed a prevalence of "fearful-avoidant" attachment style in clinical group (29.2% vs 1.1%, p=0.000); besides, ECR dimensions ("Avoidance", "Anxiety"), correlate with the severity of depressive symptoms. CONCLUSIONS: Positive family history for psychiatric disorders and an insecure romantic attachment might influence the development and the severity of perinatal depression.

Perinatal Depression and Patterns of Attachment: A Critical Risk Factor?

Background. This study aims to verify if the presence and severity of perinatal depression are related to any particular pattern of attachment. Methods. The study started with a screening of a sample of 453 women in their third trimester of pregnancy, who were administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Experience in Close Relationship (ECR). A clinical group of subjects with perinatal depression (PND, 89 subjects) was selected and compared with a control group (C), regarding psychopathological variables and attachment patterns. Results. The ECR showed a prevalence of "Fearful-Avoidant" attachment style in PND group (29.2% versus 1.1%, p < 0.001); additionally, the EPDS average score increases with the increasing of ECR dimensions (Avoidance and Anxiety). Conclusion. The severity of depression increases proportionally to attachment disorganization; therefore, we consider attachment as both an important risk factor as well as a focus for early psychotherapeutic intervention.

MMPI-2: cluster analysis of personality profiles in perinatal depression­preliminary evidence.

BACKGROUND: To assess personality characteristics of women who develop perinatal depression. METHODS: The study started with a screening of a sample of 453 women in their third trimester of pregnancy, to which was administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Minnesota Multiphasic Personality Inventory 2 (MMPI-2). A clinical group of subjects with perinatal depression (PND, 55 subjects) was selected; clinical and validity scales of MMPI-2 were used as predictors in hierarchical cluster analysis carried out. RESULTS: The analysis identified three clusters of personality profile: two "clinical" clusters (1 and 3) and an "apparently common" one (cluster 2). The first cluster (39.5%) collects structures of personality with prevalent obsessive or dependent functioning tending to develop a "psychasthenic" depression; the third cluster (13.95%) includes women with prevalent borderline functioning tending to develop "dysphoric" depression; the second cluster (46.5%) shows a normal profile with a "defensive" attitude, probably due to the presence of defense mechanisms or to the fear of stigma. CONCLUSION: Characteristics of personality have a key role in clinical manifestations of perinatal depression; it is important to detect them to identify mothers at risk and to plan targeted therapeutic interventions.

Acute psychiatric presentation of steroid-responsive encephalopathy: the under recognized side of autoimmune thyroiditis.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), also known as Hashimoto encephalopathy, represents a rare disorder of presumed autoimmune origins that can be diagnosed when a protean variety of psychiatric symptoms are present in association with elevated titers of anti-thyroid antibodies. Symptoms can have a rapid and complete remission with corticosteroid treatment. A 19-year-old girl, with clinical history of Basedow-Graves disease, has been admitted to our department after presenting acute psychiatric symptomatology. Clinical and serological findings were used to formulate the diagnosis of SREAT, confirmed by subsequent positive response to corticosteroid treatment. SREAT can mimic an acute psychiatric symptomatology, thus it seems extremely relevant for psychiatrists to consider this syndrome in differential diagnosis algorithm, especially in those patients presenting a history of autoimmune thyroid disorder, in order to ensure adequate diagnosis and treatment.

[Sensitive delusion of reference, rivisitation of a concept: clinical accounts on onset paranoid psychosis]. / Rivisitazione del concetto di delirio sensitivo: osservazioni cliniche su scompensi paranoicali all'esordio.

AIM: In this work it is discussed whether and how Kretchmer's psychopathological reflections about sensitive delusion of reference can offer a relevant interpretative key for clinicians who face cases of acute persecutory psychosis. It is argued the utility and topicality of those psychopathological concepts that aren't commonly investigated, especially in the evaluation and management of onset paranoid psychosis in an emergency ward. METHODS: We provide clinical vignettes of two young patients, admitted in the emergency psychiatry ward, who represent a concrete example of the dynamic-affective comprehension of delusional elaboration, through its embodiment in the individual biographical development. RESULTS: An interpretative key, based on this specific conceptual frame, seems to provide an integrated intervention tool that aims both to a causal comprehension and demolition of the delusional solution in onset psychotic cases. CONCLUSIONS: The rediscovery of classical psychopathological concepts appears to be a necessary process, especially in the clinical management of onset psychotic disorders. Further and more accurate researches are, in any case, needed.

[Maternal attachment patterns and personality in post partum depression]. / Modelli di attaccamento e personalità nella depressione post partum.

AIMS: This study investigates the prevalence of post partum depression (PPD) in a sample of Roman women, and the role of socio-demographic variables, personality structure and maternal attachment patterns, in order to identify primary and secondary prevention strategies. METHODS: Data were collected in two phases. During the third trimester of pregnancy, a sample of 453 women completed a socio-demographic data sheet and the Edinburgh Postnatal Depression Scale (EPDS). Among the patients scoring 12 or more at EPDS, 15 entered the second phase of the study and completed SCID-II and Adult Attachment Interview. PPD diagnosis was confirmed by the SCID-I. The study group was compared with a control group. RESULTS: Among the 453 women who were evaluated, 92 (20.3%) scored ≥12 at EPDS, 39 has been enrolled and 15 entered the study. Presence of depressive symptoms was associated with: complications in pregnancy, previous psychiatric disorders, family and marital conflicts. 66.6% of depressed mothers showed more than one diagnosis on Axis II (particularly avoidant/dependent + borderline or histrionic + dependent). The AAI showed a prevalence of insecure (33.3%) and unresolved/disorganized (46.6%) attachment pattern in the clinical group. DISCUSSION AND CONCLUSIONS: Our results suggest that psychological factors such as personality structure and attachment patterns are not only involved in post natal affective disorders, but have a key role in the onset and development of PPD.

Factors affecting interindividual differences in clozapine response: a review and case report.

OBJECTIVE: Clozapine is the most powerful new­generation antipsychotic. Although this drug leads to great therapeutic benefits, two types of undesirable conditions frequently occur with its use: side effects and resistance to treatment. Therapeutic drug monitoring of clozapine would be very useful to avoid both these situations. The necessity of monitoring the therapy is the result of a wide interindividual variability in the metabolism of clozapine. In this review, we highlight all the conditions underlying this variability, analyzing them one by one. METHODS: Relevant literature was identified through a search of MEDLINE and PubMed. In addition, the case of a treatment­resistant patient with accelerated metabolism of clozapine is reported as representative of utility of therapeutic drug monitoring in terms of clozapine dose adjustment. RESULTS: Genetic polymorphisms of cytochrome P450 enzymes and of neurotransmitter receptors; drug interactions; interactions of clozapine with other substances such as food and drink; smoking; and nonmodifiable variables such as age, ethnicity, and gender have been examined in relation to the existing scientific literature. The laboratory techniques that clinicians could use to identify these variables and adequate therapies are also reviewed.

From purines to basic biochemical concepts: Experiments for high school students.

Many high school biology courses address mainly the molecular and cellular basis of life. The complexity that underlies the most essential processes is often difficult for the students to understand; possibly, in part, because of the inability to see and explore them. Six simple practical experiments on purine catabolism as a part of a biochemistry course for 16-18 years students that require only simple equipment for thin layer chromatography have been developed, tried, and tested. These include detection and measurement of enzyme activities in biological extracts, detection of reversible and irreversible reactions, creating a pathway from consecutive reactions. They focus on purines because of their multifunctionality in biochemical processes. They allow students to grasp specific concepts and to use them as a framework for approaching metabolic complexity.

Chaperone-like activity of alpha-crystallin toward aldose reductase oxidatively stressed by copper ion.

The protective action of alpha-crystallin against copper-induced protein stress is studied using bovine lens aldose reductase (ALR2) as protein model. The oxidative inactivation of ALR2 induced by CuCl2 at the stoichiometric Cu2+/ALR2 ratio of 2/1 [I. Cecconi, M. Moroni, P.G. Vilardo, M. Dal Monte, P. Borella, G. Rastelli, L. Costantino, D. Garland, D. Carper, J.M. Petrash, A. Del Corso, U. Mura, Biochemistry 37 (1998) 14167-14174] is accompanied by protein aggregation phenomena when the metal ion concentration is increased (Cu2+/ALR2>3). Protein oxidation precedes protein precipitation. Both inactivation and precipitation of ALR2 are prevented by alpha-crystallin in a concentration-dependent manner. The rationale for the stabilization of ALR2 exerted by alpha-crystallin at low metal concentration is given on the basis of the ability of alpha-crystallin to chelate copper. However, the overall protective action exerted by alpha-crystallin at higher copper concentration may be explained invoking the contribution of the special features of alpha-crystallin to easily interact with target proteins undergoing structural rearrangement.

Discovering an accessible enzyme: Salivary α-amylase : Prima digestio fit in ore: A didactic approach for high school students.

Human salivary α-amylase is used in this experimental approach to introduce biology high school students to the concept of enzyme activity in a dynamic way. Through a series of five easy, rapid, and inexpensive laboratory experiments students learn what the activity of an enzyme consists of: first in a qualitative then in a semi-quantitative way. They also learn how some environmental effectors can influence it. The choice of a "human body" enzyme and not an anonymous commercial enzyme is a very attractive one for students. This laboratory approach will be integrated with theoretical knowledge about α-amylase, starch, their physiological meaning, and biotechnological applications.
