Language impairment in sporadic and familial (type 8) amyotrophic lateral sclerosis: A comparative study.

Language is frequently affected in patients with sporadic amyotrophic lateral sclerosis (sALS), with reduced performance in naming, syntactic comprehension, grammatical expression, and orthographic processing. However, the language profile of patients with familial type 8 ALS (ALS8), linked to p.P56S VAPB mutation, remains unclear. We investigated language in patients with ALS8 by examining their auditory comprehension and verbal production. We included three groups of participants: (1) patients with sALS (n = 20), (2) patients with familial ALS8 (n = 22), and (3) healthy controls (n = 21). The groups were matched for age, sex, and education level. All participants underwent a comprehensive language battery, including the Boston Diagnostic Aphasia Examination, the reduced Token test, letter fluency, categorical fluency (animals), word definition from the Cambridge Semantic Memory Research Battery, and a narrative discourse analysis. Participants also were evaluated using Addenbrooke's Cognitive Exam-Revised Version, the Hospital Anxiety and Depression Scale, and the ALS Functional Rating Scale-Revised. Compared to controls, sALS and ALS8 patients had impaired performance on oral (syntactic and phonological processing) comprehension and inappropriate discourse cohesion. sALS and ALS8 did not differ in any language measure. There was no correlation between language scores and functional and psychiatric scales. ALS8 patients exhibit language deficits that are independent of motor features. These findings are consistent with the current evidence suggesting that ALS8 has prominent non-motor features.

Childhood Autism Spectrum Disorder: Knowledge, Attitudes, and Practice of Health Professionals in Togo

Background. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in behavior, social communication, and interaction. Objectives. To describe health staff's knowledge, attitudes, and practices regarding ASD in Lomé. Methods. From January to March 2020, we conducted a multicenter, cross-sectional, descriptive, and analytical study on ASD in childhood. A survey was administered to a sample of healthcare professionals in 5 facilities in Lomé, Togo. A questionnaire assessed the knowledge, attitudes, and practices of ASD among 139 participants (pediatricians, neurologists, general practitioners, psychologists, speech therapists, and nurses). Results.The participation rate was 84.2 % (117 / 139). One hundred seven health workers (91.5 %) had heard of ASD. Inaccurate knowledge was observed: 65.4 % gave a good definition of autism, 73.2 % did not know the autistic triad, the early warning signs (64.6 %), or the age of onset (61.0 %). Only 22.0 % of staff were familiar with autism screening tools. The highest knowledge was significantly associated with being a speech therapist or pediatrician practicing in a tertiary health facility (p < 0,0001). Higher-graded staff also observed better knowledge levels (p = 0, 0128). Concerning attitudes or practices regarding autistic children, 26 of those surveyed (22,2 %) had already screened for ASD, of whom 23 (88,5 %) worked with other specialties in case management. Conclusion. This study highlights inappropriate knowledge, attitudes, and practices among health staff. These findings warrant the need for good initial training on ASD, awareness campaigns, and the setting up a specialized center in Togo.

Patients with autism spectrum disorders pose a challenge to the dentist in terms of implement-ing preventive and treatment measures. This is due to the hypersensitivity of these patients to unavoidable dental stimuli and communication disorders. Previously, we developed a new method of mitigating dental stimuli for neurodiverse patients, realized in a mobile application. The aim of the study was to evaluate parental satisfaction with dental care against the back-ground of using a mobile application for sensory deprivation of children with autism. The study included 168 families with neurodiverse children who worked with the mobile application for 1 year. As a subjective criterion for evaluating the effectiveness of the mobile application, the opinion of the direct user (families - study participants) was analyzed, represented by a wide range of parametrics in terms of the multidimensional concept of "satisfaction" of expectations from the use of technology. The Customer Satisfaction Index was used to measure satisfaction with the interaction with the application during one year. The dynamics of the final satisfaction index after 1 and 12 months of the study (70.75% and 84.9%, respectively) indicates a positive subjective evaluation of both the process and the result of dental treatment of neurodiverse children using the mobile application.

Peripheral intravenous catheter failure, nurse staffing levels and care complexity individual factors: A retrospective multicentre cohort study

Introduction Short peripheral intravenous catheter (PIVC) failure is a common complication that is generally underdiagnosed. Some studies have evaluated the factors associated with these complications, but the impact of care complexity individual factors and nurse staffing levels on PIVC failure is still to be assessed. The aim of this study was to determine the incidence and risk factors of PIVC failure in the public hospital system of the Southern Barcelona Metropolitan Area. Methods A retrospective multicentre observational cohort study of hospitalised adult patients was conducted in two public hospitals in Barcelona from 1st January 2016 to 31st December 2017. All adult patients admitted to the hospitalisation ward were included until the day of discharge. Patients were classified according to presence or absence of PIVC failure. The main outcomes were nurse staffing coverage (ATIC patient classification system) and 27-care complexity individual factors. Data were obtained from electronic health records in 2022. Results Of the 44,661 patients with a PIVC, catheter failure was recorded in 2,624 (5.9%) patients (2,577 [5.8%] phlebitis and 55 [0.1%] extravasation). PIVC failure was more frequent in female patients (42%), admitted to medical wards, unscheduled admissions, longer catheter dwell time (median 7.3 vs 2.2 days) and those with lower levels of nurse staffing coverage (mean 60.2 vs 71.5). Multivariate logistic regression analysis revealed that the female gender, medical ward admission, catheter dwell time, haemodynamic instability, uncontrolled pain, communication disorders, a high risk of haemorrhage, mental impairments, and a lack of caregiver support were independent factors associated with PIVC failure. Moreover, higher nurse staffing were a protective factor against PIVC failure (AUC, 0.73; 95% confidence interval [CI]: 0.72–0.74). Conclusion About 6% of patients presented PIVC failure during hospitalisation. Several complexity factors were associated with PIVC failure and lower nurse staffing levels were identified in patients with PIVC failure. Institutions should consider that prior identification of care complexity individual factors and nurse staffing coverage could be associated with a reduced risk of PIVC failure.

Cannabidiol is a behavioral modulator in BTBR mouse model of idiopathic autism

IntroductionThe prevalence of Autism Spectrum Disorder (ASD) has drastically risen over the last two decades and is currently estimated to affect 1 in 36 children in the U.S., according to the center for disease control (CDC). This heterogenous neurodevelopmental disorder is characterized by impaired social interactions, communication deficits, and repetitive behaviors plus restricted interest. Autistic individuals also commonly present with a myriad of comorbidities, such as attention deficit hyperactivity disorder, anxiety, and seizures. To date, a pharmacological intervention for the treatment of core autistic symptoms has not been identified. Cannabidiol (CBD), the major nonpsychoactive constituent of Cannabis sativa, is suggested to have multiple therapeutic applications, but its effect(s) on idiopathic autism is unknown. We hypothesized that CBD will effectively attenuate the autism-like behaviors and autism-associated comorbid behaviors in BTBR T+Itpr3tf/J (BTBR) mice, an established mouse model of idiopathic ASD.MethodsMale BTBR mice were injected intraperitoneally with either vehicle, 20 mg/kg CBD or 50 mg/kg CBD daily for two weeks beginning at postnatal day 21 ± 3. On the final treatment day, a battery of behavioral assays were used to evaluate the effects of CBD on the BTBR mice, as compared to age-matched, vehicle-treated C57BL/6 J mice.ResultsHigh dose (50 mg/kg) CBD treatment attenuated the elevated repetitive self-grooming behavior and hyperlocomotion in BTBR mice. The social deficits exhibited by the control BTBR mice were rescued by the 20 mg/kg CBD treatment.DiscussionOur data indicate that different doses for CBD are needed for treating specific ASD-like behaviors. Together, our results suggest that CBD may be an effective drug to ameliorate repetitive/restricted behaviors, social deficits, and autism-associated hyperactivity.

Effects and microbiota changes following oral lyophilized fecal microbiota transplantation in children with autism spectrum disorder

Background and purposeAutism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental disorders that is characterized by core features in social communication impairment and restricted, repetitive sensory-motor behaviors. This study aimed to further investigate the utilization of fecal microbiota transplantation (FMT) in children with ASD, both with and without gastrointestinal (GI) symptoms, evaluate the effect of FMT and analyze the alterations in bacterial and fungal composition within the gut microbiota.MethodsA total of 38 children diagnosed with ASD participated in the study and underwent oral lyophilized FMT treatment. The dosage of the FMT treatment was determined based on a ratio of 1 g of donor stool per 1 kg of recipient body weight, with a frequency of once every 4 weeks for a total of 12 weeks. In addition, 30 healthy controls (HC) were included in the analysis. The clinical efficacy of FMT was evaluated, while the composition of fecal bacteria and fungi was determined using 16S rRNA and ITS gene sequencing methods.ResultsMedian age of the 38 children with ASD was 7 years. Among these children, 84.2% (32 of 38) were boys and 81.6% (31 of 38) exhibited GI symptoms, with indigestion, constipation and diarrhea being the most common symptoms. Sample collections and assessments were conducted at baseline (week 0), post-treatment (week 12) and follow-up (week 20). At the end of the follow-up phase after FMT treatment, the autism behavior checklist (ABC) scores decreased by 23% from baseline, and there was a 10% reduction in scores on the childhood autism rating scale (CARS), a 6% reduction in scores on the social responsiveness scale (SRS) and a 10% reduction in scores on the sleep disturbance scale for children (SDSC). In addition, short-term adverse events observed included vomiting and fever in 2 participants, which were self-limiting and resolved within 24 h, and no long-term adverse events were observed. Although there was no significant difference in alpha and beta diversity in children with ASD before and after FMT therapy, the FMT treatment resulted in alterations in the relative abundances of various bacterial and fungal genera in the samples of ASD patients. Comparisons between children with ASD and healthy controls (HC) revealed statistically significant differences in microbial abundance before and after FMT. Blautia, Sellimonas, Saccharomycopsis and Cystobasidium were more abundant in children with ASD than in HC, while Dorea were less abundant. After FMT treatment, levels of Blautia, Sellimonas, Saccharomycopsis and Cystobasidium decreased, while levels of Dorea increased. Moreover, the increased abundances of Fusicatenibacter, Erysipelotrichaceae_UCG-003, Saccharomyces, Rhodotorula, Cutaneotrichosporon and Zygosaccharomyces were negatively correlated with the scores of ASD core symptoms.ConclusionsOral lyophilized FMT could improve GI and ASD related symptoms, as well as sleep disturbances, and alter the gut bacterial and fungal microbiota composition in children with ASD.Clinical Trial RegistrationChinese Clinical Trial Registry, ChiCTR2200055943.

Development of a conceptual framework to understand the stakeholder’s perspectives on needs and readiness of rural tele-practice for childhood communication disorders

Background Tele-practice promotes universal and equitable access to quality health services and emerged as an alternative to overcome physical barriers to intervention access in the 90s. There has been a steady increase in adoption since then, and during the COVID-19 pandemic, there was a surge in online modes of healthcare service delivery. Yet, tele-practice adoption and utilization in rural and remote areas are not spontaneous. Therefore, as a first step, prior to the implementation of a comprehensive tele-practice model, a baseline situational analysis was undertaken to assess the needs and readiness of parents of children with disabilities and different cadres of health care providers towards accepting tele-practice services in their settings. This paper describes the process of development of the conceptual framework that guided the baseline needs and readiness assessment (situational analysis). Methods The Bowen's feasibility framework served as the primary framework to evaluate the feasibility outcomes of the implementation. Therefore, this framework also guided the baseline situational analysis. For specificity of the framework to tele-practice, several telemedicine planning frameworks relevant for low- and middle-income countries were reviewed to identify and map suitable constructs and attributes to the Bowen’s constructs. A description of the framework selection process and a review of each of the selected telemedicine frameworks are provided. Results The constructs and attributes from this conceptual framework were used to develop the guides for focus group discussions (FGDs) and semi-structured interviews (SSIs). The guides were prepared separately for each stakeholder group. Conclusions The developed framework facilitated the assessment of needs and readiness suited to the context and among various stakeholders involved in the proposed implementation of the comprehensive model of tele-practice for childhood communication disorders in rural communities.

Diversity of Research Participant Gender, Race, and Ethnicity in Communication Sciences and Disorders: A Systematic Review and Quantitative Synthesis of American Speech-Language-Hearing Association Publications in 2020

Purpose: One manifestation of systemic inequities in communication sciences and disorders (CSD) is the chronic underreporting and underrepresentation of sex, gender, race, and ethnicity in research. The present study characterized recent demographic reporting practices and representation of participants across CSD research. Method: We systematically reviewed and extracted key reporting and participant data from empirical studies conducted in the United States with human participants published in the year 2020 in journals by the American Speech-Language-Hearing Association (ASHA; 407 articles comprising a total of 80,058 research participants, search completed in November 2021). Sex, gender, race, and ethnicity were operationalized per National Institutes of Health guidelines. Results: Sex or gender was reported in 85.5% of included studies; race in 33.7%; and ethnicity in 13.8%. Sex and gender were clearly differentiated in 3.4% of relevant studies. Where reported, median proportions for race and ethnicity were significantly different from the U.S. population, with underrepresentation noted for all non-White racial groups and Hispanic participants. Moreover, 64.7% of studies that reported sex or gender and 67.2% of studies that reported race or ethnicity did not consider these respective variables in analyses or discussions. Conclusions: At present, research published in ASHA journals frequently fails to report key demographic data summarizing the characteristics of participants. Moreover, apparent gaps in the representation of minoritized racial and ethnic groups threaten the external validity of CSD research and broader health care equity endeavors in the United States. Although our study is limited to a single year and publisher, our results point to several steps for readers that may bring greater accountability, consistency, and diversity to the discipline.

Montreal Cognitive Assessment Scores Do Not Associate With Communication Challenges Reported by Adults With Alzheimer's Disease or Parkinson's Disease.

Screening for cognitive-communication challenges in people with Alzheimer's disease (AD) or Parkinson's disease (PD) may benefit from multiple kinds of information about the client (e.g., patient-reported, performance-based). The purposes of this report are (a) to describe, using recently published score range descriptors (e.g., "mild," "moderate"), the patient-reported communication challenges of people with AD or PD using the Communicative Participation Item Bank (CPIB) and the Aphasia Communication Outcome Measure (ACOM); and (b) to examine the relationships between the performance-based Montreal Cognitive Assessment (MoCA), a cognitive screener, and patient-reported CPIB and ACOM scores. Participants were a convenience sample of 49 community-dwelling adults with AD or PD. Participants completed the measures in person as part of a larger assessment battery. MoCA total scores ranged from 7 to 28. CPIB T-scores fell in the following ranges: 31% were "within normal limits," 57% reflected "mildly" restricted participation, and 12% reflected "moderately" restricted participation. ACOM T-scores fell in the following ranges: 50% were either "within normal limits" or reflected "mild" impairment, 29% reflected "mild-moderately" impaired functional communication, and 21% reflected "moderately" impaired functional communication. There were only weak and nonsignificant correlations between T-scores on the ACOM or CPIB and scores on the MoCA, and there were no group differences on the ACOM or CPIB between individuals who screened positive versus negative on the MoCA. When screening individuals with AD or PD, patient-reported communication challenges seem to be complementary to information provided by the MoCA and perhaps most useful in screening for mild communication challenges.

Transdiagnostic considerations are critical to understanding childhood neurodevelopmental disorders

Growing dissatisfaction with the current categorical diagnostic systems has led to a movement toward transdiagnostic dimensional approaches to assessment of childhood mental health disorders. We argue that a transdiagnostic approach is especially important and appropriate when screening for neurodevelopmental disorders during early childhood. In the early childhood years, symptoms often appear in the form of developmental delays that could portend a variety of different disorders. Early intervention at this point is critical, even though a final endpoint disorder is not yet apparent. Intervening early has the potential to grow the area of weakness, possibly correcting or at least ameliorating these delays. Early intervention requires a multidisciplinary approach integrating efforts across settings and providers that monitor the development of young children. We argue here that young children’s language ability is central to the development of social cognition, and a prerequisite for adequate social functioning. Social deficits are defining features of a subset of neurodevelopmental disorders such as autism spectrum disorder and social (pragmatic) communication disorder. Critically, impairment in social functioning is common in additional neurodevelopmental disorders such as attention-deficit/hyperactivity disorder (ADHD), learning disorders, and even motor disorders. For this reason, we argue that, at the earliest sign of a possible neurodevelopmental disorder, children should be screened for language deficits prior to initiating a focused assessment for a specific type of neurodevelopmental disorder such as ADHD. Any detected language deficits should be considered in the design and implementation of the assessment, as well as the ultimate intervention plan.

Conversational Speech Behaviors Are Context Dependent.

According to the interpersonal synergy model of spoken dialogue, interlocutors modify their communicative behaviors to meet the contextual demands of a given conversation. Although a growing body of research supports this postulation for linguistic behaviors (e.g., semantics, syntax), little is understood about how this model applies to speech behaviors (e.g., speech rate, pitch). The purpose of this study is to test the hypothesis that interlocutors adjust their speech behaviors across different conversational tasks with different conversational goals. In this study, 28 participants each engaged in two different types of conversations (i.e., relational and informational) with two partners (i.e., Partner 1 and Partner 2), yielding a total of 112 conversations. We compared six acoustic measures of participant speech behavior across conversational task and partner. Linear mixed-effects models demonstrated significant differences between speech feature measures in informational and relational conversations. Furthermore, these findings were generally robust across conversations with different partners. Results suggest that contextual demands influence speech behaviors. These findings provide empirical support for the interpersonal synergy model and highlight important considerations for assessing speech behaviors in individuals with communication disorders.

Prenatal & Perinatal Risk Factors of Autism Spectrum Disorder

Background: Autism spectrum disorder (ASD) is lifelong neurodevelopmental disorder characterized by impairments in social function, communication, and certain behaviors. The etiology of ASD is unclear & it is believed to be multi-factorial, among those several prenatal & perinatal factors are found to be significant. So, the necessity of this study is to detect the presence of known risk factors of ASD which in turn may help in the early diagnosis and intervention for better long-term outcomes. Objective: To find out prenatal and perinatal risk factors of ASD. Method: A case control study was conducted with 112 cases of ASD and 201 controls of 2-6 years of age. The study was carried out in Center for Neurodevelopment and Autism in Children (CNAC), in the department of Paediatrics, Bangabandhu Sheikh Mujib Medical University and Autism Welfare Foundation (AWF). ASD was diagnosed by DSM-IV TR criteria. Mothers were interviewed and data were collected by semistructured questionnaires. Results: Total 5 risk factors were identified as the risk factors of ASD. They were: advanced paternal age (OR=2.84) and maternal age (OR=1.87); male baby (OR=2.01); environmental stress during pregnancy (OR=1.61) and preterm delivery (OR=1.80). Conclusions: It is concluded that advanced paternal age, maternal age, male baby, environmental stress during pregnancy and preterm delivery are associated with increased risk of ASD.

The long-term negative impact of childhood stroke on language

ObjectivesThis study aims to investigate the long-term language outcome in children with unilateral childhood stroke in comparison to those with perinatal strokes and typically developing individuals and to explore the impact of lesion-specific modifiers.MethodsWe examined nine patients with childhood stroke, acquired between 0;2 and 16;1 years (CHILD; 3 female, median = 13.5 years, 6 left-sided), 23 patients with perinatal strokes (PERI; 11 female, median = 12.5 years, 16 left-sided), and 33 age-matched typically developing individuals (CONTROL; 15 female, median = 12.33 years). The language outcome was assessed using age-appropriate tasks of the Potsdam Illinois Test of Psycholinguistic Abilities (P-ITPA) or the Peabody Picture Vocabulary Test (PPVT). For group comparisons, study-specific language z-scores were calculated. Non-verbal intelligence was assessed using the Test of Non-verbal Intelligence (TONI-4), language lateralization with functional MRI, and lesion size with MRI-based volumetry.ResultsAll four patients with childhood stroke who initially presented with aphasic symptoms recovered from aphasia. Patients with childhood stroke showed significantly lower language scores than those in the control group, but their scores were similar to those of the patients with perinatal stroke, after adjusting for general intelligence (ANCOVA, language z-score CHILD = −0.30, PERI = −0.38, CONTROL = 0.42). Among the patients with childhood stroke, none of the possible modifying factors, including lesion side, correlated significantly with the language outcome.ConclusionChildhood stroke, regardless of the affected hemisphere, can lead to chronic language deficits, even though affected children show a “full recovery.” The rehabilitation of children and adolescents with childhood stroke should address language abilities, even after the usually quick resolution of clear aphasic symptoms.

Editorial: Digital participation and communication disorders across the lifespan

A snapshot on introspection of autism spectrum disorder.

Autism spectrum disorder is a neurodevelopmental condition marked by restricted interests and difficulty with social communication. ASD is characterized by heightened neuroinflammation and irregular neuronal connections. ASD is more frequent in male than female with male-female ratio of around 4:1. ASD affects 2.8% or 1 in 36 8-year-olds, based on the CDC's Morbidity and Mortality Weekly Report. Various factors like Environmental, Genetic, Epigenetic and Developmental factors are linked with genesis of ASD. Repetitive behaviors, Impaired communication skills, difficulty with social interaction are some of the clinical features of ASD. Current Pharmacotherapy of ASD limits to management of symptoms only, not cure. The stem cell therapy has a promising potential to be a breakthrough in treating ASD. Various types of stem cells have been successfully tested in children with ASD. AI has a potential to emerge as a tool for early detection of ASD. Robotics can assist the children with ASD to overcome the challenges associated with ASD.

Professionalism in Communication Sciences and Disorders: Consideration of Diversity, Equity, Inclusion, and Access

Purpose: This tutorial aims to provide an in-depth discussion of professionalism in communication sciences and disorders (CSD) with consideration of diversity, equity, inclusion, and access. Students, practitioners, and faculty in CSD are taught and held to expectations of professionalism. However, criteria for professionalism often do not fully consider diversity, equity, inclusion, and access. Method: Relevant literature on professionalism and diversity, equity, and inclusion is reviewed and summarized. Case scenarios are also shared to provide examples of how these aspects are not currently considered in the discipline of CSD. Results: The current definitions of professionalism are vague and oftentimes exclude cultural differences. Because the majority of American Speech-Language-Hearing Association membership and leadership groups are from the mainstream culture, the definitions and attributes of professional norms have been influenced by mainstream culture. Conclusions: Recent publications on professionalism and professional behavior in medicine have discussed the impact of racialized professionalism norms on increasing diversity of medical students and trainees. It is imperative to resonate such issues in the CSD profession, because there is a growing number of students and practitioners from minority groups. This tutorial addresses how the discipline of CSD can reflect cultural responsiveness to the standards for students, practitioners, and faculty. Several solutions are suggested.

Subcortical Aphasia

Subcortical Aphasia

A study on the reliability and validity of the Japanese version of the Scenario Test for people with chronic stroke-induced aphasia: A cross-sectional study.

The Scenario Test is recognised for its effectiveness in assessing the interactive aspects of functional communication in people with post-stroke aphasia (PWA). To develop a Japanese version of the Scenario Test (Scenario Test-JP) and assess its reliability and validity. Among 66 participants, we selected 61 individuals: 34 PWA and 27 healthy controls (HCs). We modified the Scenario Test-JP based on the UK version and subsequently evaluated its reliability (internal consistency, test-retest and intra-rater and inter-rater reliabilities) and validity (convergent and discriminant) by comparing PWA and HCs. The Scenario Test-JP showed strong reliability with a Cronbach's α of 0.93, test-retest reliability with an intraclass correlation coefficient (ICC) of 0.97, intra-rater reliability with an ICC of 0.95-1.00, and inter-rater reliability with an ICC of 0.96. The validity of the test was confirmed with concurrent scores ranging from ρ = 0.37 to 0.76 (p < 0.05) and known-groups validity (p < 0.001, r = -0.56). The reliability and validity of the Scenario Test-JP align with those of the original Dutch version and the UK and Greek versions. Additionally, the assessment can now include extended alternative communication methods, such as digital devices, indicating the potential of the Scenario Test-JP for modern Japanese speech-language therapy. What is already known on the subject Interactive communication is a facet of functional communication and is crucial for evaluating engagement and participation of people with aphasia (PWA) in speech-language therapy. The Scenario Test provides valuable information for planning speech-language treatment strategies by assessing dialogic communication. What this study adds This study describes the development of the Scenario Test-JP for use with Japanese speakers and Japanese PWA, which is adapted from the Scenario Test UK version. This study evaluated the reliability and validity of this assessment tool and provided supporting evidence. What are the clinical implications of this work? The reliability and validity of the Scenario Test-JP were consistent with those of the Dutch, UK and Greek versions. The Scenario Test-JP contributes to speech-language therapy in Japan, where high-quality support for the activities and participation of PWA is required. Insights from the Scenario Test The Scenario Test plays a crucial role in evaluating the functional communication skills of people with post-stroke aphasia (PWA). Enhancing functional communication has been linked to improved social engagement among PWA, which in turn influences their overall quality of life (QOL). Issues addressed by the Scenario Test The Scenario Test aids in delineating rehabilitation objectives for activities and participation among PWA, particularly concerning functional communication. The test facilitates tailored support for PWAs' interactive communication and forms the foundation for appropriate speech-language therapy interventions. Transformation of speech-language therapy (SLT) in Japan through the introduction of the Scenario Test-JP The integration of the Scenario Test-JP could enhance the SLT services provided to PWA in Japan. With Japan experiencing an unprecedented ageing population, the prevalence of social isolation and diminished QOL resulting from communication disorders like stroke-induced aphasia is expected to rise. Consequently, the SLT rehabilitation sector in Japan is actively seeking effective interventions to support functional communication among PWA. Hence, the adoption of the Scenario Test-JP is anticipated to streamline the evaluation of functional communication, facilitating the judicious selection and timely provision of assistance to PWA in SLT, including guidance on communication partner support and communication skill training.

Establishment of a two-hit mouse model of environmental factor induced autism spectrum disorder

Autism spectrum disorder (ASD) is a group of developmental diseases characterized by social dysfunction and repetitive stereotype behaviors. Besides genetic mutations, environmental factors play important roles in the development of ASD. Valproic acid (VPA) is widely used for modeling environmental factor induced ASD in rodents. However, traditional VPA modeling is low-in-efficiency and the phenotypes often vary among different batches of experiments. To optimize this ASD-modeling method, we tested “two-hit” hypothesis by single or double exposure of VPA and poly:IC at the critical time points of embryonic and postnatal stage. The autistic-like behaviors of mice treated with two-hit schemes (embryonic VPA plus postnatal poly:IC, embryonic poly:IC plus postnatal VPA, embryonic VPA plus poly: IC, or postnatal VPA plus poly:IC) were compared with mice treated with traditional VPA protocol. The results showed that all single-hit and two-hit schemes produced core ASD phenotypes as VPA single treatment did. Only one group, namely, mice double-hit by VPA and poly:IC simultaneously at E12.5 showed severe impairment of social preference, social interaction and ultrasonic communication, as well as significant increase of grooming activity and anxiety-like behaviors, in comparation with mice treated with the traditional VPA protocol. These data demonstrated that embryonic two-hit of VPA and poly:IC is more efficient in producing ASD phenotypes in mice than the single-hit of VPA, indicating this two-hit scheme could be utilized for modeling environmental factors induced ASD.
