Background Cardiac hypertrophy is an important pre-pathology of heart failure, which will ultimately lead to heart failure. However, the mechanisms underlying pathological cardiac hypertrophy remain largely unknown. The aim of this study is to elucidate the effects and mechanisms of histidine triad nucleotide binding protein 1 (HINT1) in cardiac hypertrophy and heart failure. Methods HINT1 was down-regulated in human hypertrophic heart samples compared with non-hypertrophic samples by mass spectrometry analysis. Hint1 knockout mice were challenged with TAC (transverse aortic constriction) surgery. Cardiac specific overexpression of HINT1 mice by intravenous injection of adeno-associated viral (AAV9) encoding Hint1 under the cardiac troponin T (cTnT) promoter were subjected to TAC. Unbiased transcriptional analyses were used to identify the downstream targets of HINT1. AAV9 bearing shRNA against Homeobox A5 (Hoxa5) was administrated to investigate whether the effects of HINT1 on cardiac hypertrophy were HOXA5 ting cardiac hypertrophy. Conclusions HINT1 protects against cardiac hypertrophy through suppressing HOXA5 expression. These findings indicate that HINT1 may be a potential target for therapeutic interventions in cardiac hypertrophy and heart failure.Purpose This study examined the effect of Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment on toddlers’ expressive vocabulary and phonology. Parent acceptability of VAULT treatment was also considered. Method We used a nonconcurrent multiple baseline single case experimental design with three late talking toddlers aged 21-25 months. The treatment was delivered twice weekly in 30-min sessions for 8 weeks by a rotating team of four speech-language pathologists. Toddlers heard three of their 10 strategically selected target words a minimum of 64 times in play activities each session. Expressive vocabulary and phonology was assessed pre-post, with parent interviews conducted posttreatment. Results All toddlers increased production of target words and expressive vocabulary. Ambient expressive vocabulary size increased by an average of 16 words per week (range of 73-169 words learned over the treatment period). On a 20-item, single-word speech assessment, the toddlers’ phonetic inventories increased on average from three to seven consonants, and five to eight vowels. Two toddlers used protowords pretreatment, which were replaced by recognizable attempts at words posttreatment. Parents reported the treatment was acceptable for the child and their family with future consideration of parent-based delivery of the treatment in the home. Conclusions The results of this treatment provide further evidence of a model of intervention informed by the principles of implicit learning, and the interconnectedness of phonological and lexical learning. Investigation is required to establish the efficacy and feasibility of VAULT in clinical contexts.

The program aimed to detect hearing disorders and increase awareness among parents of hearing problems. Method A hearing screening program was conducted in all elementary schools of the biggest region in Poland. A total of 34,618 first-graders were screened. The hearing screening protocol included video otoscopy and pure-tone audiometry. The program also included an information campaign directed to the local community and educational meetings between parents and medical staff. Results The estimated prevalence of hearing loss was 11%. Unilateral hearing loss was more common than bilateral hearing loss. WS6 clinical trial Mild hearing loss was more frequent than moderate (or worse) hearing loss. In otoscopy, the most common positive result was otitis media with effusion. Parents and medical staff took part in 1,608 educational meetings, broadening the parents’ knowledge of how to care for hearing. Conclusions A hearing screening program not only provides data on the prevalence of childhood hearing problems but is also an avenue for providing the local community with valuable knowledge about how to care for hearing. This study demonstrated the importance for systematic monitoring of children’s hearing status and of increasing awareness among parents and teachers of the significance of hearing loss. The hearing screening of children starting school should become a standard part of school health care programs.Purpose Recording young children’s vocalizations through wearables is a promising method to assess language development. However, accurately and rapidly annotating these files remains challenging. Online crowdsourcing with the collaboration of citizen scientists could be a feasible solution. In this article, we assess the extent to which citizen scientists’ annotations align with those gathered in the lab for recordings collected from young children. Method Segments identified by Language ENvironment Analysis as produced by the key child were extracted from one daylong recording for each of 20 participants 10 low-risk control children and 10 children diagnosed with Angelman syndrome, a neurogenetic syndrome characterized by severe language impairments. Speech samples were annotated by trained annotators in the laboratory as well as by citizen scientists on Zooniverse. All annotators assigned one of five labels to each sample Canonical, Noncanonical, Crying, Laughing, and Junk. This allowed the derivation of two child-level vocalization metrics the Linguistic Proportion and the Canonical Proportion. Results At the segment level, Zooniverse classifications had moderate precision and recall. More importantly, the Linguistic Proportion and the Canonical Proportion derived from Zooniverse annotations were highly correlated with those derived from laboratory annotations. Conclusions Annotations obtained through a citizen science platform can help us overcome challenges posed by the process of annotating daylong speech recordings. Particularly when used in composites or derived metrics, such annotations can be used to investigate early markers of language delays.
