The long way to bilingualism: the peculiar case of multilingual South Tyrol

In the present contribution we discuss the challenges and the results of learning a second language in South Tyrol, the multilingual border region in northern Italy where the autochthonous German- and Ladinspeaking communities have cohabited with the Italian-speaking community since the end of the First World War. The picture resulting from the data collected in the Kolipsi project (Eurac/DiScoF), an extensive linguistic and psychosocial investigation about South Tyrolean secondary school pupils now in its second edition, gives precious inputs to all entities that intervene in the process of attitude formation and change, ranging from the family environment to politics.En el presente trabajo, debatimos los retos y los resultados del proceso de aprendizaje de segundas lenguas en el Tirol del Sur, la región fronteriza multilingüe del norte de Italia donde las comunidades autóctonas hablantes de alemán y ladino han convivido con la comunidad italohablante desde el fin de la Primera Guerra Mundial. La imagen resultante de los datos recogidos en el proyecto Kolipsi (Eurac/DiScoF), una investigación abarcadora tanto lingüística como psicosocial sobre alumnado de secundaria del Tirol del Sur, proporciona información muy valiosa a todas las entidades que intervienen en el proceso de la formación y el cambio de las actitudes, desde el entorno familiar hasta el ámbito de la política

Quality of life in a cohort of Kenyan children with cerebral palsy

Aim: The objective of the study was to evaluate the quality of life in Kenyan children (age 4–18 years) with cerebral palsy (CP). Methods: A cross-sectional descriptive study was conducted. Children with CP were recruited from the pediatric clinics at the Aga Khan hospital Nairobi (AKUHN). Parent proxy-reports using CPQoL-child and CPQoL-adolescents were obtained. Clinical and demographic data were compiled from medical records and parent interviews. A Likert scale was utilized to determine QoL across several domains. Results: One hundred and fourteen child–parent dyads with CP were recruited. The median age of study participants was 8 years (IQR 3–13 years), with males being the majority (57.02 %). Parent proxy-reports using CPQoL-child scale were obtained for n = 93 and CPQoL-adolescents for n = 21 respondents. Parents in both groups reported low domain QoL scores pertaining to function, family health and rehabilitation service accessibility. Interpretation: Stigma, accessibility to services, therapies and schooling, particularly for children with severe functional limitations, remains a concern. Caregivers would benefit from awareness campaigns of available supports and from local community respite programs. Where national support systems exist, there are critical inefficiencies in service delivery to target population

A novel PLP1 mutation further expands the clinical heterogeneity at the locus

Objectives: To characterize at clinical and molecular levels a family presenting with X-linked recessive Hereditary Spastic Paraplegia (HSP). Background: HSPs are a large group of genetically heterogeneous neurodegenerative disorders characterized by progressive upper motor neuron signs. Mutations in the proteolipid protein (PLP1) gene have been identified in families linked to the SPG2 locus on chromosome Xq22. However, Pelizaeus-Merzbacher disease (PMD) is also an X-linked recessive neurological disorder caused by PLP1 mutations. Methods: The SPG2 locus was investigated by linkage analysis in the family. The PLP1 gene was screened by sequencing. We present findings in a large French-Canadian family with an X-linked recessive HSP. The proband presented early with developmental delay and developed progressive spastic paraplegia. He has been wheelchair-bound since the age of three years. At the latest follow-up, he was 20 years-old and had severe spasticity predominantly affecting the lower extremities, moderate cerebellar dysfunction, and optic atrophy. Results: Linkage to SPG2 was established and a G to A mutation (MIR) in the initiation codon of the PLP1 gene was identified, likely resulting in the complete absence of proteolipid protein. Conclusions: We report a new PLP1 gene mutation in a patient with a clinical phenotype consistent with a PLP1 null syndrome

Pediatric Cerebral Palsy in Africa: Where Are We?

Cerebral palsy is the most common cause of physical disability in children worldwide. However, little is reported on this condition in the African context. Doctors from 22 countries in Africa, and representatives from a further 5 countries outside Africa, met to discuss the challenges in the evaluation and management of children with cerebral palsy in Africa and to propose service needs and further research. Basic care is limited by the poor availability of diagnostic facilities or medical personnel with experience and expertise in managing cerebral palsy, exacerbated by lack of available interventions such as medications, surgical procedures, or even regular therapy input. Relevant guidelines are lacking. In order to guide services for children with existing disabilities, to effectively target the main etiologies and to develop preventive strategies for the continent, research priorities must include multicenter collaborative studies looking at the prevalence, risk factors, and treatment of cerebral palsy

Play and Be Happy? Leisure Participation and Quality of Life in School-Aged Children with Cerebral Palsy

The objective of this study was to examine the association between leisure participation and quality of life (QoL) in school-age children with cerebral palsy (CP). Leisure participation was assessed using the Children’s Assessment of Participation and Enjoyment (CAPE) and QoL using the Pediatric Quality of Life Inventory (PedsQL). Pearson correlation coefficients were calculated to examine the association between CAPE and PedsQL scores, and a multiple linear regression model was used to estimate QoL predictors. Sixty-three children (mean age 9.7±2.1 years; 39 male) in GMFCS levels I–V were included. Intensity of participation in active-physical activities was significantly correlated with both physical (r=0.34, P=0.007) and psychosocial well-being (r=0.31, P=0.01). Intensity and diversity of participation in skill-based activities were negatively correlated with physical well-being (r=−0.39, P=0.001, and r=−0.41, P=0.001, resp.). Diversity and intensity of participation accounted for 32% (P=0.002) of the variance for physical well-being and 48% (P<0.001) when age and gross motor functioning were added. Meaningful and adapted leisure activities appropriate to the child’s skills and preferences may foster QoL

The phantom illusion

It is well known that visible luminance gradients may generate contrast effects. In this work we present a new paradoxical illusion in which the luminance range of gradual transitions has been reduced to make them invisible. By adopting the phenomenological method proposed by Kanizsa, we have found that unnoticeable luminance gradients still generate contrast effects. But, most interestingly, we have found that when their width is narrowed, rather than generating contrast effects on the surrounded surfaces, they generate an assimilation effect. Both high- and low-level interpretations of this “phantom” illusion are critically evaluated

Increased serum miR-193a-5p during non-alcoholic fatty liver disease progression: diagnostic and mechanistic relevance

Background & Aims: Serum microRNAs (miRNAs) levels are known to change in non-alcoholic fatty liver disease (NAFLD) and may serve as useful biomarkers. This study aimed to profile miRNAs comprehensively at all NAFLD stages.Methods: We profiled 2,083 serum miRNAs in a discovery cohort (183 NAFLD cases representing the complete NAFLD spectrum and 10 population controls). MiRNA libraries generated by HTG EdgeSeq were sequenced by Illumina NextSeq. Selected serum miRNAs were profiled in 372 additional NAFLD cases and 15 population controls by quantitative reverse transcriptase-polymerase chain reaction.Results: Levels of 275 miRNAs differed between cases and population controls. Fewer differences were seen within individual NAFLD stages but miR-193a-5p consistently the showed increased levels in all comparisons. Relative to NAFL/NASH with mild fibrosis (stage 0/1), three miRNAs (miR-193a-5p, miR-378d and miR378d) were increased in cases with NASH and clinically significant fibrosis (stage 2-4), seven (miR193a-5p, miR-378d, miR-378e, miR-320b, c, d & e) increased in cases with NAFLD Activity Score (NAS) 5-8 compared with lower NAS, and three (miR-193a-5p, miR-378d, miR-378e) increased but one (miR-19b-3p) decreased in steatosis, activity, and fibrosis "activity" (SAF-A) score 2-4 compared with lower SAF-A. The significant findings for miR-193a-5p were replicated in the additional NAFLD cohort. Studies in Hep G2 cells showed that following palmitic acid treatment, miR-193a-5p expression decreased significantly. Gene targets for miR-193a-5p were investigated in liver RNAseq data for a case subgroup (n=80); liver GPX8 levels correlated positively with serum miR-193a-5p. Conclusions: Serum miR-193a-5p levels correlate strongly with NAFLD activity grade and fibrosis stage. MiR-193a-5p may have a role in the hepatic response to oxidative stress and is a potential clinically tractable circulating biomarker for progressive NAFLD
