Abstract
INTRODUCTION Childhood maltreatment, particularly emotional abuse (EA), has been identified as a significant risk factor for the development of eating disorders (EDs). This study investigated the association between EA and ED symptoms while considering multiple potential mediators. METHODS Participants included 151 individuals with Anorexia Nervosa (AN), 115 with Bulimia Nervosa (BN), and 108 healthy controls. The Childhood trauma questionnaire, the Toronto Alexithymia scale, the Behavioral inhibition System, and the Eating Disorder Inventory 2 scale were completed before treatment. A mediator path model was conducted in each group: EA was set as independent variable, eating symptoms as dependent variables and ineffectiveness, sensitivity to punishment, alexithymia, and impulsivity as mediators. RESULTS In individuals with AN, impulsivity emerged as a significant mediator between EA and desire for thinness and bulimic behaviors. Conversely, in individuals with BN, sensitivity to punishment was found to mediate the association between EA and dissatisfaction with one's body. Ineffectiveness and difficulty identifying emotions were identified as transdiagnostic mediators in both clinical groups. No mediation effect was found in healthy individuals. DISCUSSION The simultaneous assessment of multiple mediators in a unique model outlines the complex interplay between childhood EA and ED psychopathology. Improving ineffectiveness, emotion identification, sensitivity to punishment and impulsivity and exploring their relations with early emotional abuse may represent treatment targets in individuals with EDs and childhood trauma.

Abstract
OBJECTIVES The study involves the effect of hypothalamus-pituitary-adrenal hormones disorders, and related to oxidative stress in individuals with PTSD to those in the healthy group after they experience a specific event that results in a congenital illness or limb loss. METHODS Obtaining serum samples from males exclusively in cases where psychiatrists have determined that the men have experienced psychological damage brought on by a particular tragedy, and testing the men for hypothalamus-pituitary-adrenal axis and oxidative stress parameters in comparison to healthy participants. RESULTS It was observed that there was a notable rise in cortisol levels (5.60 ± 0.93) at 4 pm compared with healthy control (3.43 ± 0.64) resulting from the stimulating effect of the pituitary gland, and this increase has a role in raising levels of oxidative stress in patients total oxidant status (1.08 ± 0.13) compared with control (0.70 ± 0.10). High oxidative stress may lead to increased prolactin levels and decreased testosterone levels. CONCLUSIONS Transmission of incorrect chemical signals from the central nervous system has a role in causing disturbances in hormonal levels of the hypothalamus and its associated glands, and thus an imbalance in the metabolic rate due to high cortisol. Also, high levels of prolactin hormones play a role in a significant decrease in testosterone levels.

Abstract
The cerebellum, traditionally linked to voluntary motor coordination, is now recognized for its role in nonmotor functions, including cognitive and social behaviors. This expanded understanding is vital for identifying neurodevelopmental disorders such as autism spectrum disorder (ASD), where cerebellar abnormalities are common. Recent research has identified specific cerebellar circuits contributing to these diverse functions, revealing interconnected pathways that regulate both motor and social behaviors. The cerebellum communicates extensively with the cerebral cortex, thalamus, and limbic structures through converging and diverging pathways, integrating sensory and motor information to fine-tune outputs and influence higher-order functions. Mouse models have been instrumental in dissecting cerebellar functions, with studies using genetic and neuroanatomical techniques to manipulate specific circuits and observe behavioral outcomes. Disruptions in cerebellar pathways can lead to motor deficits and social impairments, mirroring human neurodevelopmental disorders. This review explores the anatomical and functional organization of cerebellar pathways in mice, their role in behavior, and the implications of cerebellar dysfunction in disorders such as ASD. Understanding these pathways enhances knowledge of cerebellar contributions to behavior and informs therapeutic strategies for cerebellar and neurodevelopmental disorders, emphasizing the integral role of the cerebellum in motor and social functions.

Abstract
This systematic review aimed to summarize the evidence on the existence of a distinct phenotypic expression of Eating Disorders (EDs) associated with childhood maltreatment (CM), the so-called maltreated eco-phenotype of EDs. PRISMA standards were followed. Articles providing data about the characteristics of individuals with an ED reporting CM were included. Relevant results were extracted and summarized. A quality assessment was performed. A total of 1207 records were identified and screened, and 97 articles published between 1994 and 2023 were included. Findings revealed distinct biological and clinical features in patients with EDs reporting CM, including neuroanatomical changes, altered stress responses, ghrelin levels, inflammation markers, and gut microbiota composition. Clinically, CM correlated with severer eating behaviors, higher psychiatric comorbidity, impulsivity, emotional dysregulation, and risky behaviors. Additionally, CM was associated with poorer treatment outcomes, especially in general psychopathology and psychiatric comorbidities. This review highlighted the need to move towards an etiologically informed nosography, recognizing CM not merely as a risk factor, but also as an etiologic agent shaping different eco-phenotypic variants of EDs.

Abstract
Anorexia nervosa (AN) is a complex neuropsychiatric disorder with genetic and epigenetic components that results in reduced food intake combined with alterations in the reward-processing network. While studies of patient cohorts and mouse models have uncovered genes and epigenetic changes associated with the disease, neuronal networks and brain areas preferentially activated and metabolic changes associated with reduced food intake, the underlying molecular and cellular mechanisms remain unknown. The use of both 2D in vitro cultures and 3D models, namely organoids and spheroids, derived from either human embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs), would allow identification of cell type-specific changes associated with AN and comorbid diseases, to study preferential connections between brain areas and organs, and the development of therapeutic strategies.
