ABSTRACT
Autoimmune encephalitis is a rapidly progressive inflammatory brain disease. Gamma-aminobutyric acid type B (GABAB) receptor autoimmune encephalitis is a rare subtype characterized by distinct clinical features. Diagnosis can be especially challenging when typical limbic symptoms and neuroimaging findings are absent. This case report underscores the importance of identifying this condition and starting immunosuppressive treatment promptly. A 59-year-old man presented with gait disturbances, dysarthria, and severe ataxia without cognitive impairment. Initial examinations, including a brain MRI, were unremarkable, except for an elevated cell count and protein in the cerebrospinal fluid. Despite receiving initial empirical antiviral treatment, his symptoms worsened, prompting the administration of intravenous methylprednisolone and immunoglobulin. After these immunosuppressive therapies, the cerebellar symptoms showed gradual improvement. Subsequent testing for antibodies to the GABAB receptor was positive in both the serum and cerebrospinal fluid. Follow-up MRI revealed cerebellar atrophy, consistent with a diagnosis of GABAB receptor-associated acute cerebellitis. This case illustrates that cerebellar symptoms can occur in the absence of more common limbic manifestations in GABAB receptor autoimmune encephalitis. The progression of cerebellar atrophy following an initially normal MRI is a significant finding that offers supporting evidence for the diagnosis of cerebellitis. A review of the literature identified similar cases of acute cerebellitis without limbic symptoms, although neuroimaging abnormalities in the cerebellum were not reported. Our case underscores the importance of increased clinical awareness and consideration of autoimmune causes, even when neuroimaging appears normal. Early and appropriate immunosuppressive therapy may help change the course of the disease and enhance patient outcomes.
ABSTRACT
This data article describes the dataset of the International COVID-19 Impact on Parental Engagement Study (ICIPES). ICIPES is a collaborative effort of more than 20 institutions to investigate the ways in which, parents and caregivers built capacity engaged with children's learning during the period of social distancing arising from global COVID-19 pandemic. A series of data were collected using an online survey conducted in 23 countries and had a total sample of 4,658 parents/caregivers. The description of the data contained in this article is divided into two main parts. The first part is a descriptive analysis of all the items included in the survey and was performed using tables and figures. The second part refers to the construction of scales. Three scales were constructed and included in the dataset: 'parental acceptance and confidence in the use of technology', 'parental engagement in children's learning' and 'socioeconomic status'. The scales were created using Confirmatory Factor Analysis (CFA) and Multi-Group Confirmatory Analysis (MG-CFA) and were adopted to evaluate their cross-cultural comparability (i.e., measurement invariance) across countries and within sub-groups. This dataset will be relevant for researchers in different fields, particularly for those interested in international comparative education.
ABSTRACT
Previous studies have tested multivariate models of bulimia pathology development, documenting that a confluence of perfectionism, body dissatisfaction, and low self-esteem is predictive of disordered eating. However, attempts to replicate these results have yielded controversial findings. The objective of the present study was to test an interactive model of perfectionism, weight and shape concerns, and self-esteem in a sample of patients affected by Eating Disorder (ED). One-hundred-sixty-seven ED patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), and they completed the Eating Disorder Examination Questionnaire (EDE-Q), the Rosenberg Self-Esteem Scale (RSES), and the Multidimensional Perfectionism Scale (MPS-F). Several mediation analysis models were fit to test whether causal effects of concern over weight and shape on the frequency of bulimic episodes were mediated by perfectionism and moderated by low levels of self-esteem. Contrary to our hypotheses, we found no evidence that the causal relationship investigated was mediated by any of the dimensions of perfectionism. As a secondary finding, the dimensions of perfectionism, perceived criticism and parental expectations, were significantly correlated with the presence of bulimic symptoms. The validity of the interactive model remains controversial, and may be limited by an inadequate conceptualization of the perfectionism construct.

OBJECTIVE: The prognosis for eating disorders (ED) is unsatisfactory, and the literature about outcome indicators is controversial. The present study evaluates the roles of self-esteem, personality disorders (PD), and dissociation as outcome predictors. METHOD: Fifty-seven ED outpatients were recruited from a population beginning a Cognitive Behavioral Therapy-Enhanced (CBT-E) treatment. All patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), the Structured Clinical Interview for DSM-IV Axis II (SCID-II), and completed the Eating Disorder Examination Questionnaire (EDE-Q), the Dissociation Questionnaire (DIS-Q), and the Rosenberg Self-Esteem Scale (RSES). One month after the end of treatment, recovery was evaluated as meeting the DSM-IV criteria for EDs. RESULTS: A small group of patients recovered (42.2%). Low self-esteem and dissociation results correlated with a negative outcome. DISCUSSION: Dissociation may be an important moderator of psychotherapy and treatment success, as already suggested by previous studies on non-eating-related disorders.
