Effects of a Universal Design for Learning (UDL) Training Course on the Development Teachers’ Competences: A Systematic Review
2023
The aim of the study was to analyze the effects of a Universal Design for Learning (UDL) training course on the competence development of teachers working in inclusive classrooms. This model provides a useful framework to address this issue, establishing evidence-based guidelines for creating learning environments that meet the needs of all learners. The move towards inclusive education requires teachers to reassess their pedagogical practices by considering the contributions of neuroscience and cognitive psychology to support effective teaching in heterogeneous classrooms. Consequently, teacher training should include, in its curricula, practices and evidence that support teachers to develop skills for working in inclusive contexts. The study aimed to answer the main research question, namely, how effective the UDL approach is in developing teachers’ skills. To answer this question, a systematic review was conducted in different databases allowing the extraction and the analysis of 12 studies. Results were organized around the four dimensions linked to the model of the European Profile of Inclusive Teacher (PIT). Outcomes of the review highlighted three main findings: 1. a UDL training course has significant effects on students’ diversity valuing skills; 2. the effectiveness of the course appears to be independent of its duration, delivery mode, and the type of teachers to whom it is addressed; 3. UDL training fosters the implementation of accessible lesson planning and implementation skills. Still uncertain or unexplored, however, are the effects on teachers’ areas of collaboration and reflective practice.

Translation and Transcultural Adaptation of the Universal Design for Learning Observation Measurement Tool (UDL-OMT)
2024
Universal Design for Learning (UDL) is a widely accepted educational approach in the United States, and its adoption is increasingly observed in Europe and other international contexts. This growing implementation necessitates the development of standardized criteria for consistent evaluation of UDL in educational settings. This study describes the methodology for translating and cross-culturally adapting the UDL Observation and Measurement Tool (UDL-OMT), originally developed by Basham et al., into French and Italian. It also reports the results of a pretest conducted to evaluate the adapted instruments. Preliminary results indicate a high degree of adaptability of UDL-OMT for use in the French- and Italian-speaking regions of Switzerland. These results are discussed in the context of the potential for wider dissemination and validation of the instrument in French- and Italian-speaking classrooms.

CDKL5 and Shootin1 Interact and Concur in Regulating Neuronal Polarization
2016
In the last years, the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene has been associated with epileptic encephalopathies characterized by the early onset of intractable epilepsy, severe developmental delay, autistic features, and often the development of Rett syndrome-like features. Still, the role of CDKL5 in neuronal functions is not fully understood. By way of a yeast two hybrid screening we identified the interaction of CDKL5 with shootin1, a brain specific protein acting as a determinant of axon formation during neuronal polarization. We found evidence that CDKL5 is involved, at least in part, in regulating neuronal polarization through its interaction with shootin1. Indeed, the two proteins interact in vivo and both are localized in the distal tip of outgrowing axons. By using primary hippocampal neurons as model system we find that adequate CDKL5 levels are required for axon specification. In fact, a significant number of neurons overexpressing CDKL5 is characterized by supernumerary axons, while the silencing of CDKL5 disrupts neuronal polarization. Interestingly, shootin1 phosphorylation is reduced in neurons silenced for CDKL5 suggesting that the kinase affects, directly or indirectly, the post-translational modification of shootin1. Finally, we find that the capacity of CDKL5 to generate surplus axons is attenuated in neurons with reduced shootin1 levels, in agreement with the notion that two proteins act in a common pathway. Altogether, these results point to a role of CDKL5 in the early steps of neuronal differentiation that can be explained, at least in part, by its association with shootin1.

Although Rett syndrome (RTT) represents one of the most frequent forms of severe intellectual disability in females worldwide, we still have an inadequate knowledge of the many roles played by MeCP2 (whose mutations are responsible for most cases of RTT) and their relevance for RTT pathobiology. Several studies support a role of MeCP2 in the regulation of synaptic plasticity and homeostasis. At the molecular level, MeCP2 is described as a repressor capable of inhibiting gene transcription through chromatin compaction. Indeed, it interacts with several chromatin remodeling factors, such as HDAC-containing complexes and ATRX. Other studies have inferred that MeCP2 functions also as an activator; a role in regulating mRNA splicing and in modulating protein synthesis has also been proposed. Further, MeCP2 avidly binds both 5-methyl- and 5-hydroxymethyl-cytosine. Recent evidence suggests that it is the highly disorganized structure of MeCP2, together with its post-translational modifications (PTMs) that generate and regulate this functional versatility. Indeed, several reports have demonstrated that differential phosphorylation of MeCP2 is a key mechanism by which the methyl binding protein modulates its affinity for its partners, gene expression and cellular adaptations to stimuli and neuronal plasticity. As logic consequence, generation of phospho-defective Mecp2 knock-in mice has permitted associating alterations in neuronal morphology, circuit formation, and mouse behavioral phenotypes with specific phosphorylation events. MeCP2 undergoes various other PTMs, including acetylation, ubiquitination and sumoylation, whose functional roles remain largely unexplored. These results, together with the genome-wide distribution of MeCP2 and its capability to substitute histone H1, recall the complex regulation of histones and suggest the relevance of quickly gaining a deeper comprehension of MeCP2 PTMs, the respective writers and readers and the consequent functional outcomes.

Mutations in the methyl‐CpG‐binding protein 2 (MeCP2) are associated with Rett syndrome and other neurological disorders. MeCP2 represses transcription mainly by recruiting various co‐repressor complexes. Recently, MeCP2 phosphorylation at Ser 80, Ser 229 and Ser 421 was shown to occur in the brain and modulate MeCP2 silencing activities. However, the kinases directly responsible for this are largely unknown. Here, we identify the homeodomain‐interacting protein kinase 2 (HIPK2) as a kinase that binds MeCP2 and phosphorylates it at Ser 80
in vitro
and
in vivo
. HIPK2 modulates cell proliferation and apoptosis, and the neurological defects of
Hipk2
‐null mice indicate its role in proper brain functions. We show that MeCP2 cooperates with HIPK2 in induction of apoptosis and that Ser 80 phosphorylation is required together with the DNA binding of MeCP2. These data are, to our knowledge, the first that describe a kinase associating with MeCP2, causing its specific phosphorylation
in vivo
and, furthermore, they reinforce the role of MeCP2 in regulating cell growth.
Rett syndrome is a severe neurological disorder caused by mutations in the gene MECP2. Bracaglia and colleagues now identify the kinase HIPK2 as capable of specifically phosphorylating MeCP2 protein at Serine 80 in vivo. They show that MeCP2 cooperates with HIPK2 to induce apoptosis, providing insight into the function of this disease‐associated protein.

Severe acute respiratory syndrome coronavirus 2 is a recently discovered pathogen responsible of coronavirus disease 2019 (COVID-19). The immunological changes associated with this infection are largely unknown.
We evaluated the peripheral blood mononuclear cells profile of 63 patients with COVID-19 at diagnosis. We also assessed the presence of association with inflammatory biomarkers and the 28-day mortality.
Lymphocytopenia was present in 51 of 63 (80.9%) patients, with a median value of 720 lymphocytes/µl (IQR 520-1,135). This reduction was mirrored also on CD8+ (128 cells/µl, IQR 55-215), natural killer (67 cells/µl, IQR 35-158) and natural killer T (31 cells/µl, IQR 11-78) cells. Monocytes were preserved in total number but displayed among them a subpopulation with a higher forward and side scatter properties, composed mainly of cells with a reduced expression of both CD14 and HLA-DR. Patients who died in the 28 days from admission (N=10, 15.9%), when compared to those who did not, displayed lower mean values of CD3+ (337.4 cells/µl vs 585.9 cells/µl; p=0.028) and CD4+ cells (232.2 cells/µl vs 381.1 cells/µl; p=0.042) and an higher percentage of CD8+/CD38+/HLA-DR+ lymphocytes (13.5% vs 7.6%; p=0.026).
The early phases of COVID-19 are characterized by lymphocytopenia, predominance of Th2-like lymphocytes and monocytes with altered immune profile, which include atypical mononuclear cells.

Specific immune suppression types have been associated with a greater risk of severe COVID-19 disease and death. We analyzed data from patients >17 years that were hospitalized for COVID-19 at the “Fondazione IRCCS Ca′ Granda Ospedale Maggiore Policlinico” in Milan (Lombardy, Northern Italy). The study included 1727 SARS-CoV-2-positive patients (1,131 males, median age of 65 years) hospitalized between February 2020 and November 2022. Of these, 321 (18.6%, CI: 16.8–20.4%) had at least one condition defining immune suppression. Immune suppressed subjects were more likely to have other co-morbidities (80.4% vs. 69.8%, p < 0.001) and be vaccinated (37% vs. 12.7%, p < 0.001). We evaluated the contribution of immune suppression to hospitalization during the various stages of the epidemic and investigated whether immune suppression contributed to severe outcomes and death, also considering the vaccination status of the patients. The proportion of immune suppressed patients among all hospitalizations (initially stable at <20%) started to increase around December 2021, and remained high (30–50%). This change coincided with an increase in the proportions of older patients and patients with co-morbidities and with a decrease in the proportion of patients with severe outcomes. Vaccinated patients showed a lower proportion of severe outcomes; among non-vaccinated patients, severe outcomes were more common in immune suppressed individuals. Immune suppression was a significant predictor of severe outcomes, after adjusting for age, sex, co-morbidities, period of hospitalization, and vaccination status (OR: 1.64; 95% CI: 1.23–2.19), while vaccination was a protective factor (OR: 0.31; 95% IC: 0.20–0.47). However, after November 2021, differences in disease outcomes between vaccinated and non-vaccinated groups (for both immune suppressed and immune competent subjects) disappeared. Since December 2021, the spread of the less virulent Omicron variant and an overall higher level of induced and/or natural immunity likely contributed to the observed shift in hospitalized patient characteristics. Nonetheless, vaccination against SARS-CoV-2, likely in combination with naturally acquired immunity, effectively reduced severe outcomes in both immune competent (73.9% vs. 48.2%, p < 0.001) and immune suppressed (66.4% vs. 35.2%, p < 0.001) patients, confirming previous observations about the value of the vaccine in preventing serious disease.
