    背景:Prep-4-RT是一项共同设计的阶梯式护理多模式康复计划,适用于计划接受头颈部癌症(HNC)放射治疗的人。训练前,发生在诊断和治疗开始之间,旨在改善患者的健康,以减少当前和未来损伤的发生率和严重程度。HNC治疗可能令人痛苦,并对功能和生活质量产生不利影响。HNC患者的社会脆弱性增加,包括更高的社会经济劣势率和生活方式习惯增加癌症风险。HNC治疗对身体和心理的高度影响以及该人群的社会脆弱性增加,需要对最佳护理途径进行调查。比如康复。本文介绍了一种评估Prep-4-RT可行性的研究方案,旨在为HNC患者准备放疗的身体和心理影响。
    方法:至少60例成人HNC患者,计划接受放疗(有或没有化疗),将在五个月内招募。所有参与者将获得Prep-4-RT自我管理资源。通过筛查确定为高风险的参与者还将在开始放射治疗之前与相关的专职医疗专业人员一起提供个性化干预措施(心理学家,营养师,言语病理学家和物理治疗师)。参与者将完成评估调查,评估他们使用Prep-4-RT资源和干预措施的经验。临床医生还将完成项目评估调查。主要的可行性结果包括采用(吸收和尝试的意图)和保真度(坚持专科康复途径)。次要可行性结果包括Prep-4-RT的可接受性(患者和临床医生)和满意度(患者)以及运营成本。可行性结果数据将使用精确二项式和单样本t检验进行分析,视情况而定。
    背景:已在墨尔本的PeterMacCallum癌症中心获得道德批准,澳大利亚。结果将在全国会议上发表,并在同行评审的期刊上发表,以便参与接受放射治疗的HNC患者的护理的临床医生可以访问。如果发现护理模式是可行和可接受的,向其他癌症中心的可转移性和可扩展性,或其他癌症类型,可能会被调查。
    背景:ANZCTA(澳大利亚新西兰临床试验注册中心)ACTRN12623000770662。
    BACKGROUND: Prep-4-RT is a co-designed stepped-care multimodal prehabilitation program for people scheduled to receive radiotherapy for head and neck cancer (HNC). Prehabilitation, which occurs between diagnosis and treatment commencement, aims to improve a patient\'s health to reduce the incidence and severity of current and future impairments. HNC treatment can be distressing and has detrimental impacts on function and quality of life. HNC patients have increased social vulnerabilities including higher rates of socio-economic disadvantage and engagement in lifestyle habits which increase cancer risk. High levels of physical and psychological impacts of HNC treatment and increased social vulnerabilities of this population warrant investigation of optimal pathways of care, such as prehabilitation. This paper describes a research protocol to evaluate the feasibility of Prep-4-RT, which was designed to prepare HNC patients for the physical and psychological impacts of radiotherapy.
    METHODS: At least sixty adult HNC patients, scheduled to receive radiotherapy (with or without chemotherapy), will be recruited over a five-month period. All participants will receive access to Prep-4-RT self-management resources. Participants identified through screening as high-risk will also be offered individualised interventions with relevant allied health professionals prior to the commencement of radiotherapy (psychologists, dietitians, speech pathologists and physiotherapists). Participants will complete evaluation surveys assessing their experiences with Prep-4-RT resources and interventions. Clinicians will also complete program evaluation surveys. Primary feasibility outcomes include adoption (uptake and intention to try) and fidelity (adherence to the specialist prehabilitation pathway). Secondary feasibility outcomes include acceptability (patient and clinician) of and satisfaction (patient) with Prep-4-RT as well as operational costs. Feasibility outcome data will be analysed using exact binomial and one-sample t tests, as appropriate.
    BACKGROUND: Ethics approval has been obtained at the Peter MacCallum Cancer Centre in Melbourne, Australia. Results will be presented at national conferences and published in peer-reviewed journal(s) so that it can be accessed by clinicians involved in the care of HNC patients receiving radiotherapy. If the model of care is found to be feasible and acceptable, the transferability and scalability to other cancer centres, or for other cancer types, may be investigated.

    背景:在远程医疗快速整合后,许多专职医疗服务现在同时提供远程医疗和当面服务,以应对COVID-19大流行。然而,关于如何决定通过远程医疗与亲自提供哪些临床预约,人们知之甚少。
    目的:本研究的目的是探索临床医生在考虑为客户提供远程医疗时的决策,包括他们考虑的因素以及他们如何权衡这些不同的因素,以及临床医生对COVID-19封锁以外的远程医疗公用事业的看法。
    方法:我们使用反身性主题分析,从焦点小组收集的数据与来自语言病理学学科的16名儿科社区专职健康临床医生,职业治疗,社会工作,心理学,和咨询。
    结果:研究结果表明,决策复杂,涉及4大类:技术,客户和家庭,临床服务,和临床医生。三个主题描述了他们对COVID-19封锁之外的远程医疗使用的看法:“灵活的远程医疗使用,远程医疗可以优于面对面治疗,\"和\"担心亲自服务可能会被替换。
    结论:研究结果强调了社区相关健康环境中决策的复杂性,以及临床医生在将经验证据与自己的临床经验进行协调时遇到的挑战。
    BACKGROUND: Many allied health services now provide both telehealth and in-person services following a rapid integration of telehealth as a response to the COVID-19 pandemic. However, little is known about how decisions are made about which clinical appointments to provide via telehealth versus in person.
    OBJECTIVE: The aim of this study is to explore clinicians\' decision-making when contemplating telehealth for their clients, including the factors they consider and how they weigh up these different factors, and the clinicians\' perceptions of telehealth utility beyond COVID-19 lockdowns.
    METHODS: We used reflexive thematic analysis with data collected from focus groups with 16 pediatric community-based allied health clinicians from the disciplines of speech-language pathology, occupational therapy, social work, psychology, and counseling.
    RESULTS: The findings indicated that decision-making was complex with interactions across 4 broad categories: technology, clients and families, clinical services, and clinicians. Three themes described their perceptions of telehealth use beyond COVID-19 lockdowns: \"flexible telehealth use,\" \"telehealth can be superior to in-person therapy,\" and \"fear that in-person services may be replaced.\"
    CONCLUSIONS: The findings highlight the complexity of decision-making in a community-allied health setting and the challenges experienced by clinicians when reconciling empirical evidence with their own clinical experience.

    背景:术语原发性进行性失语症(PPA)描述了一组以语言为主导的痴呆。延缓疾病的治疗,目前缺乏缓慢或逆转的PPA进展,尽管近年来已经开发了许多治疗PPA症状的干预措施。不幸的是,探索这些干预措施有效性的研究使用了各种不同的结果衡量标准,限制可比性。有更多的结构,除了单词检索,这对于在研究文献中没有受到太多关注的PPA患者来说很重要。现有的痴呆和非进行性失语症的核心结果集(COS)不能满足PPA患者的需求。强调需要为PPA开发特定的COS。
    方法:该方案描述了一项三阶段研究,以确定在研究和临床实践中用于PPA干预的COS。第一阶段系统审查将确定现有的演讲,在研究文献中用于检查PPA干预措施有效性的语言和沟通措施。采用名义分组技术,阶段2将确定PPA患者及其家人的最重要结果。在第1阶段和第2阶段收集的数据将与项目PPI小组联合分析,并将告知第2阶段修改的德尔菲共识研究,以在一系列研究学科中确定PPA的核心结果测量集,这些研究学科为PPA患者进行干预研究。
    背景:已在每个国家的合作机构中分别寻求研究第二阶段的伦理批准,并在手稿中进行了详细说明。第3阶段已获得UCL语言和认知部伦理委员会主席的伦理批准,项目IDLCD-2023-06。在第1、第2和第3阶段开展的工作将在开放获取同行评审的期刊文章中发表,并在国际科学会议上发表。

    BACKGROUND: The term primary progressive aphasia (PPA) describes a group of language-led dementias. Disease-modifying treatments that delay, slow or reverse progression of PPA are currently lacking, though a number of interventions to manage the symptoms of PPA have been developed in recent years. Unfortunately, studies exploring the effectiveness of these interventions have used a variety of different outcome measures, limiting comparability. There are more constructs, apart from word retrieval, that are important for people with PPA that have not received much attention in the research literature. Existing core outcome sets (COS) for dementia and non-progressive aphasia do not meet the needs of people with PPA, highlighting a need to develop a specific COS for PPA.
    METHODS: This protocol describes a three-stage study to identify a COS for PPA interventions in research and clinical practice. The stage 1 systematic review will identify existing speech, language and communication measures used to examine the effectiveness of interventions for PPA in the research literature. Employing a nominal group technique, stage 2 will identify the most important outcomes for people with PPA and their families. The data collected in stages 1 and 2 will be jointly analysed with the project PPI group and will inform the stage 2 modified Delphi consensus study to identify a core outcome measurement set for PPA among a range of research disciplines undertaking intervention studies for people with PPA.
    BACKGROUND: Ethical approval for stage 2 of the study has been sought individually in each country at collaborating institutions and is stated in detail in the manuscript. Stage 3 has been granted ethical approval by the Chairs of UCL Language and Cognition Department Ethics, Project ID LCD-2023-06. Work undertaken at stages 1, 2 and 3 will be published in open-access peer-reviewed journal articles and presented at international scientific conferences.

    OBJECTIVE: Speech sound disorder (SSD) describes a \'persistent difficulty with speech sound production that interferes with speech intelligibility or prevents verbal communication\'. There is a need to establish which care pathways are most effective and efficient for children with SSD. Comparison of care pathways requires clearly defined, evidence-based, interventions and agreement on how to measure the outcomes. At present, no definitive list of assessments, interventions or outcomes exists. The objective of this umbrella review paper is to provide a rigorous and detailed list of assessments, interventions and outcomes which target SSD in children.
    METHODS: In December 2022, a systematic search of Ovid Medline, OVID Embase, CINAHL, PsycInfo and Cochrane and a number of grey literature platforms were undertaken. 18 reviews were included, and subsequently 415 primary research articles were assessed for data related to assessments, interventions or outcomes. The AMSTAR (Assessing the Methodological Quality of Systematic Reviews) framework was used to assess the quality of the retained reviews.
    METHODS: Reviews were retained which took place in any setting.
    METHODS: The population is children of any age with a diagnosis of SSD of unknown origin.
    METHODS: Reviews reporting outcomes, assessment and interventions for children with SSD.
    RESULTS: Extraction and analysis identified 37 assessments, 46 interventions and 30 outcome measures used in research reporting of SSD. Not all of the listed outcomes were linked to specific outcome measurement tools, but these were measurable through the use of one or more of the assessments extracted from the retained reviews.
    CONCLUSIONS: The findings of this review will be used to develop a Core Outcome Set for children with SSD. The findings are part of a rigorous process essential for advancing healthcare research and practice in the specific area of speech and language therapy for children with SSD.

    从语音录音中自动识别口吃者(ARS)可以促进对口吃者的客观评估和干预。然而,ARS系统的性能可能取决于如何对语音数据进行分段和标记以进行训练和测试。本研究比较了两种分割方法:基于事件的分割方法,根据他们的流利程度来划分演讲片段,和基于间隔的,它使用固定长度的片段,而不考虑流畅性。
    机器学习模型在基于间隔和基于事件的口吃语音语料库上进行了训练和评估。模型使用从语音信号中提取的声学和语言特征以及由最先进的自动语音识别系统生成的转录。
    结果表明,基于事件的分割比基于间隔的分割具有更好的ARS性能,如通过接收器操作特性的曲线下面积(AUC)所测量的。结果表明,由于分割方法的不同,数据的质量和数量存在差异。包含语言特征改善了对整个单词重复的检测,但不是其他类型的口吃。
    研究结果表明,基于事件的分割比基于间隔的分割更适合ARS,因为它保留了口吃的确切边界和类型。语言特征提供了有用的信息,可将超词汇不流与流利的语音分开,但可能无法捕获口吃的声学特征。未来的工作应该探索更强大和多样化的功能,以及更大、更具代表性的数据集,开发有效的ARS系统。
    UNASSIGNED: Automatic recognition of stutters (ARS) from speech recordings can facilitate objective assessment and intervention for people who stutter. However, the performance of ARS systems may depend on how the speech data are segmented and labelled for training and testing. This study compared two segmentation methods: event-based, which delimits speech segments by their fluency status, and interval-based, which uses fixed-length segments regardless of fluency.
    UNASSIGNED: Machine learning models were trained and evaluated on interval-based and event-based stuttered speech corpora. The models used acoustic and linguistic features extracted from the speech signal and the transcriptions generated by a state-of-the-art automatic speech recognition system.
    UNASSIGNED: The results showed that event-based segmentation led to better ARS performance than interval-based segmentation, as measured by the area under the curve (AUC) of the receiver operating characteristic. The results suggest differences in the quality and quantity of the data because of segmentation method. The inclusion of linguistic features improved the detection of whole-word repetitions, but not other types of stutters.
    UNASSIGNED: The findings suggest that event-based segmentation is more suitable for ARS than interval-based segmentation, as it preserves the exact boundaries and types of stutters. The linguistic features provide useful information for separating supra-lexical disfluencies from fluent speech but may not capture the acoustic characteristics of stutters. Future work should explore more robust and diverse features, as well as larger and more representative datasets, for developing effective ARS systems.

    背景:全球语音和语言治疗师(SLT)报告挑战,提供推荐,基于证据的干预强度为儿童的言语声音障碍(SSD)。诸如服务限制和/或家庭环境之类的挑战对获得最佳治疗强度的影响。现有的研究表明,授权和培训父母在家里提供干预,除了SLT支持,提供了一种可能的解决方案,以增加接受SSD的儿童的干预强度。数字健康可以增加密集家庭实践的可及性,并有助于维持对治疗活动的参与。需要进一步探索是什么使父母对SSD儿童实施的干预有效,对于谁和在什么情况下。本文概述了现实主义者审查的协议,旨在探索有效的数字父母主导干预措施的有效成分和环境因素。
    方法:一个现实主义的综述将探讨研究问题,以下六个阶段。审查范围将确定,和最初的计划理论将被开发关于什么在数字父母实施的SSD干预中工作,为谁,如何,为什么和在什么情况下。相关二级数据,通过正式的搜索策略确定,将被选中,已评估,使用现实主义原则进行分析和综合,以测试和进一步完善初始计划理论。这个过程将发展精致的基础解释理论,捕捉上下文之间的相互作用,干预的机制和结果。一个专家指导小组将提供洞察力,为解释性理论提供信息,搜索,和传播。
    背景:本审查不需要道德批准。审查中完善的计划理论将为更广泛的研究的下一阶段提供信息。随后的现实主义评估将与关键利益相关者一起测试和进一步完善理论。在此之后,基础程序理论将用于共同生产数字工具,支持父母提供家庭干预和SLT支持。
    Speech and language therapists (SLTs) worldwide report challenges with providing recommended, evidence-based intervention intensity for children with speech sound disorder (SSD). Challenges such as service constraints and/or family contexts impact on access to optimal therapy intensity. Existing research indicates that empowering and training parents to deliver intervention at home, alongside SLT support, offers one possible solution to increasing the intensity of intervention children with SSD receive. Digital health could increase accessibility to intensive home practice and help sustain engagement with therapy activities. Further exploration is needed around what makes parent-implemented interventions for children with SSD effective, for who and in which situations. This paper outlines the protocol for a realist review which aims to explore the active ingredients and contextual factors of effective digital parent-led interventions.
    A realist review will explore the research question, following six stages. The scope of the review will be determined, and initial programme theories will be developed about what works in digital parent-implemented interventions for SSD, for whom, how, why and in what circumstances. Relevant secondary data, identified through a formal search strategy, will be selected, appraised, analysed and synthesised using realist principles to test and further refine the initial programme theories. This process will develop refined underpinning explanatory theories which capture the interaction between contexts, mechanisms and outcomes of the intervention. An expert steering group will provide insight to inform explanatory theories, searches, and dissemination.
    Ethical approval is not required for this review. The refined programme theories from the review will inform the next stages of a wider study. A subsequent realist evaluation will test and further refine theories with key stakeholders. Following this, the underpinning programme theory will be used to coproduce a digital tool, to support parents to deliver home intervention alongside SLT support.

    目的:这项横断面比较研究旨在分析和比较有和没有听力障碍(HI)叙述的泰米尔语儿童的故事语法成分。
    方法:这项研究采用了横截面,比较设计来评估和比较叙事结构。
    方法:数据是在钦奈的SriRamachandra高等教育与研究学院收集的,印度。
    方法:30名儿童参加了这项研究,包括15名使用人工耳蜗的严重至严重听力损失的儿童和15名听力正常的儿童。参与者是语言年龄匹配的3-5岁儿童,精通泰米尔语。
    方法:本研究未实施具体干预措施。
    方法:主要结果指标集中在故事语法成分上,包括设置,字符,启动事件,内部计划,尝试,结果,和决议。这些组件是通过孩子们的叙述复述来评估的。
    结果:叙述分析显示两组之间存在显着差异。听力正常的儿童比HI的儿童表现出更高的故事语法元素代表性。
    结论:研究结果表明,与HI儿童相比,听力正常的儿童在讲故事中表现出对故事结构的更熟练的理解和利用。这项研究强调了叙事分析在语言评估中的重要性,特别是对于有HI的儿童。需要结合适当语言刺激技术的量身定制干预措施,以提高儿童的HI叙事技能。有必要在这一领域进行进一步的研究。
    This cross-sectional comparative study aimed to analyse and compare the story-grammar components in Tamil-speaking children with and without hearing impairment (HI) narratives.
    The study used a cross-sectional, comparative design to assess and compare narrative structures.
    Data were collected at the Sri Ramachandra Institute of Higher Education and Research in Chennai, India.
    30 children participated in the study, including 15 children with severe to profound hearing loss who used cochlear implants and 15 with normal hearing. The participants were language-age-matched children aged 3-5 years, proficient in Tamil.
    No specific interventions were implemented in this study.
    The primary outcome measures focused on story-grammar components, including settings, characters, initiating events, internal plans, attempts, outcomes, and resolution. These components were evaluated through narrative retellings by the children.
    Analysis of the narratives revealed significant differences between the two groups. Children with normal hearing demonstrated a higher representation of story-grammar elements than children with HI.
    The findings suggest that children with normal hearing exhibit a more proficient understanding and utilisation of story structure in their story-telling than children with HI. This study highlights the importance of narrative analysis in language assessment, particularly for children with HI. Tailored interventions incorporating appropriate language stimulation techniques are needed to enhance children\'s narrative skills with HI. Further research in this area is warranted.

    帕金森病(Parkinson’sdisease,PD)是世界上仅次于阿尔茨海默病的第二大神经退行性疾病。早期诊断PD具有挑战性,因为它进化缓慢,其症状逐渐消失。最近的研究表明,语音变化可用作PD早期诊断的出色生物标志物。在这项研究中,我们提出了一种基于Chirplet变换(CT)的新方法,用于使用语音信号诊断PD。我们使用CT来获得每个语音记录的时频矩阵(TFM),我们从TFM中提取了基于时频的熵(TFE)特征。统计分析表明,TFE特征反映了由于PD而在语音中发生的语音变化,因此可用于对PD和健康对照(HC)个体进行分类。使用PC-GITA数据库中的元音和单词验证了所提出框架的有效性。利用遗传算法选择最优特征子集,而支持向量机(SVM),决策树(DT),K-近邻(KNN),和朴素贝叶斯(NB)分类器用于分类。TFE特征优于呼吸和梅尔频率倒谱系数(MFCC)特征。与其他机器学习分类器相比,SVM分类器最有效。使用元音/a/和单词/atleta/可以达到98%和99%的最高分类准确率,分别。结果表明,提出的基于CT的熵特征使用人的语音有效地诊断PD。
    Parkinson\'s disease (PD) is the second most prevalent neurodegenerative disorder in the world after Alzheimer\'s disease. Early diagnosing PD is challenging as it evolved slowly, and its symptoms eventuate gradually. Recent studies have demonstrated that changes in speech may be utilized as an excellent biomarker for the early diagnosis of PD. In this study, we have proposed a Chirplet transform (CT) based novel approach for diagnosing PD using speech signals. We employed CT to get the time-frequency matrix (TFM) of each speech recording, and we extracted time-frequency based entropy (TFE) features from the TFM. The statistical analysis demonstrates that the TFE features reflect the changes in speech that occurs in the speech due to PD, hence can be used for classifying the PD and healthy control (HC) individuals. The effectiveness of the proposed framework is validated using the vowels and words from the PC-GITA database. The genetic algorithm is utilized to select the optimum features subset, while a support vector machine (SVM), decision tree (DT), K-Nearest Neighbor (KNN), and Naïve Bayes (NB) classifiers are employed for classification. The TFE features outperform the breathiness and Mel frequency cepstral coefficients (MFCC) features. The SVM classifier is most effective compared to other machine-learning classifiers. The highest classification accuracy rates of 98% and 99% are achieved using the vowel /a/ and word /atleta/, respectively. The results reveal that the proposed CT-based entropy features effectively diagnose PD using the speech of a person.
