The purpose of this two-year study, supported in part by the National Endowment for the Arts (NEA), was to examine the impact of \"musically trained\" early childhood specialists on the music achievement and emergent literacy achievement of preschool students. The sample, obtained through use of a letter of recruitment mailed to a regional group of National Association for the Education of Young Children (NAEYC) members, consisted of 11 teachers who met the criteria for the project and their respective students (N = 165). Following a year of intensive staff development training in musicianship skill and pedagogical strategies for guiding young children’s music development, the teachers implemented the curriculum in the second year and several measures were used to collect data relative to student music and literacy outcomes. Analyses included the nonparametric Mann-Whitney U-test and multivariate techniques of MANCOVA and multiple regression. Results were mixed for music achievement. Median scores were similar for the experimental and control groups on use of singing voice. Students’ tonal pattern achievement in the experimental group was significantly higher but no significant differences were found in children’s rhythm-pattern achievement. When controlling for age and prior knowledge, the music intervention significantly increased children’s oral vocabulary and grammatic understanding and was especially effective for children who began with lower literacy skills.

Although the title of this chapter differs from that by Hargreaves and Zimmerman (1992) in the first edition of this Handbook, we further develop their themes. As Hargreaves and Zimmerman warned us then, the scope of the topic remains enormous to date. We acknowledge this difficulty and our debt to the previous authors, who made an important contribution in clarifying some issues of musical development. They also have raised many more questions, which we address throughout this chapter. Although we shall take a somewhat different approach, there is a necessary continuity between their work and ours, and we shall refer to their work fairly frequently. In this endeavor, the authors have been asked to focus on the quality of the research under review, adopting a critically selective stance. They also have been asked to deal substantially with work with which they have been closely associated, namely that of Gordon and Swanwick and Tillman. This inevitably affects the balance of the text and the reader should not therefore expect equal weight placed on each and every researcher. As a preliminary, we note the gradual shift from the concept of inherited talents, for example, Seashore and Kwalwasser (Kwalwasser & Dykema, 1930; Seashore, 1938) and the related notion of musical intelligence (Wing, 1961), to the ideas of music abilities (Bentley, 1966) and aptitude (Gordon, 1997a). The research on specific musical abilities, such as aural discrimination, singing, or instrumental playing, has been summarized and discussed in a number of publications (Boyle, 1992; Deutsch, 1982; Shuter-Dyson & Gabriel, 1968).

In the last decade, the sequence-specific transcription factor double homeobox 4 (DUX4) has gone from being an obscure entity to being a key factor in important physiological and pathological processes. We now know that expression of DUX4 is highly regulated and restricted to the early steps of embryonic development, where DUX4 is involved in transcriptional activation of the zygotic genome. While DUX4 is epigenetically silenced in most somatic tissues of healthy humans, its aberrant reactivation is associated with several diseases, including cancer, viral infection and facioscapulohumeral muscular dystrophy (FSHD). DUX4 is also translocated, giving rise to chimeric oncogenic proteins at the basis of sarcoma and leukemia forms. Hence, understanding how DUX4 is regulated and performs its activity could provide relevant information, not only to further our knowledge of human embryonic development regulation, but also to develop therapeutic approaches for the diseases associated with DUX4. Here, we summarize current knowledge on the cellular and molecular processes regulated by DUX4 with a special emphasis on FSHD muscular dystrophy.

Background Non-invasive ventilation (NIV) has been recommended as the best respiratory support for preterm infants with respiratory distress syndrome (RDS). However, the best NIV technique to be used as first intention in RDS management has not yet been established. Nasal intermittent positive pressure ventilation (NIPPV) may be synchronized (SNIPPV) or non-synchronized to the infant’s breathing efforts. The aim of the study is to evaluate the short-term effects of SNIPPV vs. NIPPV on the cardiorespiratory events, trying to identify the best ventilation modality for preterm infants at their first approach to NIV ventilation support. Methods An unmasked randomized crossover study with three treatment phases was designed. All newborn infants < 32 weeks of gestational age with RDS needing NIV ventilation as first intention or after extubation will be consecutively enrolled in the study and randomized to the NIPPV or SNIPPV arm. After stabilization, enrolled patients will be alternatively ventilated with two different techniques for two time frames of 4 h each. NIPPV and SNIPPV will be administered with the same ventilator and the same interface, maintaining continuous assisted ventilation without patient discomfort. During the whole duration of the study, the patient’s cardiorespiratory data and data from the ventilator will be simultaneously recorded using a polygraph connected to a computer. The primary outcome is the frequency of episodes of oxygen desaturation. Secondary outcomes are the number of the cardiorespiratory events, FiO 2 necessity, newborn pain score evaluation, synchronization index, and thoracoabdominal asynchrony. The calculated sample size was of 30 patients. Discussion It is known that NIPPV produces a percentage of ineffective acts due to asynchronies between the ventilator and the infant’s breaths. On the other hand, an ineffective synchronization could increase work of breathing. Our hypothesis is that an efficient synchronization could reduce the respiratory work and increase the volume per minute exchanged without interfering with the natural respiratory rhythm of the patient with RDS. The results of this study will allow us to evaluate the effectiveness of the synchronization, demonstrating whether SNIPPV is the most effective non-invasive ventilation mode in preterm infants with RDS at their first approach to NIV ventilation.

Background/Objectives: Inflammatory bowel diseases (IBDs) comprise a group of chronic idiopathic disorders, including ulcerative colitis (UC), Crohn’s disease (CD), and indeterminate colitis (IC). Complex genetic factors, in addition to environmental triggers, have been shown to play a fundamental role in the pathogenesis of IBD, contributing to disease susceptibility. The transition of adolescents with inflammatory bowel disease (IBD) to adult care represents a significant challenge for patients, their families, and healthcare providers. Approximately 25% of individuals with IBD receive a diagnosis before the age of 16, and this population is at increased risk for adverse clinical outcomes. As a result, the transition of care has garnered substantial attention in the scientific and clinical communities over the past decade. This study aims to analyze a cohort of pediatric Sardinian patients with IBD to assess clinical characteristics at diagnosis and at the time of transition and determine potential correlations between NOD2/CARD15 gene variants and HLA class II with the disease phenotype. Methods: From January 2014 to August 2024, we performed an observational, cross-sectional study that included pediatric patients with IBD enrolled in the only pediatric IBD reference center in Sardinia. Data were obtained from the patients’ medical records and from a questionnaire administered at the inclusion visit. In addition, we genotyped a portion of our cohort for the Leu1007fsinsC (SNP13), Gly908Arg (SNP12), and Arg702Trp (SNP8) variants of the NOD2/CARD15 gene, as well as for HLA-DRB1, -DQA1, and -DQB1 class II genes. The obtained results were compared with pediatric data from the national epidemiological IBD registry and existing literature. Results: Seventy-one IBD patients were enrolled (UC 43, CD 28, M 34, F 37). Median age at diagnosis was 12.2 years (IQR 2–17). After a median disease duration of 5 years (IQR: 1–16), only three UC patients experienced proximal extension of proctitis or left-sided colitis, and no CD patients experienced new localizations of disease. Fifteen patients developed extraintestinal manifestations. No significant difference was found in median diagnostic delay (DD) between UC [4 months (IQR: 1–84)] and CD patients [4.5 months (IQR: 1–48)]. At the transition visit, overall, twenty-nine patients (42%) were exposed to one biologic agent (vs. 3% at baseline; p < 0.02); 3 patients (4%) were exposed to two or more biologic agents. 7% of patients (5/71) underwent surgery. By comparing the distribution of NOD2/CARD15 SNPs between pediatric patients and an adult CD population, we found a significant association between gene allelic variants and pediatric onset (p = 0.00048). Our study also revealed a statistically significant association between Sardinian pediatric patients carrying NOD2/CARD15 mutations and early-onset CD (p < 0.009492), along with a stenosing phenotype (p < 0.024) and increased surgical risk (p < 0.026). No significant associations were observed between HLA class II alleles and IBD in our population. Conclusions: Our results provide important insights into the clinical and epidemiological features of the pediatric IBD population. In addition, our study highlights the significant role of NOD2/CARD15 gene polymorphisms in pediatric onset CD. These variants influence the age of onset and disease phenotype, characterized by greater severity and a higher risk of surgical intervention in pediatric patients.
