Neurodegenerative disorders (NDDs) represent an unprecedented public health burden. These disorders are clinically heterogeneous and therapeutically challenging, but advances in discovery science and trial methodology offer hope for translation to new treatments. Against this background, there is an urgent unmet need for biomarkers to aid with early and accurate diagnosis, prognosis and monitoring throughout the care pathway and in clinical trials.

Investigations routinely used in clinical care and trials are often invasive, expensive, time-consuming, subjective and ordinal. Speech data represent a potentially scalable, non-invasive, objective and quantifiable digital biomarker that can be acquired remotely and cost-efficiently using mobile devices, and analysed using state-of-the-art speech signal processing and machine learning approaches. This prospective case–control observational study of multiple NDDs aims to deliver a deeply clinically phenotyped longitudinal speech dataset to facilitate development and evaluation of speech biomarkers.

People living with dementia, motor neuron disease, multiple sclerosis and Parkinson’s disease are eligible to participate. Healthy individuals (including relatives or carers of participants with neurological disease) are also eligible to participate as controls. Participants complete a study app with standardised speech recording tasks (including reading, free speech, picture description and verbal fluency tasks) and patient-reported outcome measures of quality of life and mood (EuroQol-5 Dimension-5 Level, Patient Health Questionnaire 2) every 2 months at home or in clinic. Participants also complete disease severity scales, cognitive screening tests and provide optional samples for blood-based biomarkers at baseline and then 6-monthly. Follow-up is scheduled for up to 24 months. Initially, 30 participants will be recruited to each group. Speech recordings and contemporaneous clinical data will be used to create a dataset for development and evaluation of novel speech-based diagnosis and monitoring algorithms.

Digital App for Speech and Health Monitoring Study was approved by the South Central—Hampshire B Ethics Committee (REC ref. 24/SC/0067), NHS Lothian (R&D ref. 2024/0034) and NHS Forth Valley (R&D ref. FV1494). Results of the study will be submitted for publication in peer-reviewed journals and conferences. Data from the study will be shared with other researchers and used to facilitate speech processing challenges for neurological disorders. Regular updates will be provided on the Anne Rowling Regenerative Neurology Clinic web page and social media platforms.

Cleft lip and/or palate (CL/P) is a lifelong condition affecting one in 700 births. In the UK, individuals born with CL/P follow a care pathway at specialist regional cleft centres, which includes input from a range of professionals including surgeons, speech and language therapists, cleft specialist nurses, orthodontists, dentists and clinical psychologists. The cleft centres provide care from diagnosis to early adulthood. Individuals born with CL/P are typically discharged from routine care at their cleft centre between the ages of 15 and 25 years.

Outcome measures of cleft care are currently gathered at different timepoints across the treatment pathway nationally and include outcomes for speech, growth, dental health and psychosocial well-being. However, there is no consistent reporting of outcomes for young adults when they complete routine care, meaning we do not know whether variation in outcomes exists and what this might look like.

This research programme will investigate whether outcomes vary based on factors such as geographical location, biological sex, socioeconomic status or ethnicity. By understanding how outcomes might vary, and the scale and type of variation, we plan to work with young adults born with CL/P and specialist clinicians to develop ways to ensure that everyone born with CL/P in the UK receives the optimum care to meet their needs.

Cleft@18–23 is an observational study of young adults born with CL/P. Recruitment is planned across all regions of the UK, beginning in April 2025 with research clinics scheduled to run between June 2025 and May 2027. The recruitment target is 640 participants born with CL/P. Participants with all cleft diagnoses, including those with additional syndromic diagnoses, will be eligible for recruitment. We will recruit participants from all ethnic and socioeconomic backgrounds. Data collection will include self-report participant questionnaires, speech samples, a hearing screen, two-dimensional and three-dimensional medical photographs, an intraoral scan and a dental assessment. A range of descriptive and inferential statistical analyses will explore variation in outcomes across different groups.

The Cleft@18–23 study obtained ethical approval from the South West-Frenchay Research Ethics Committee on 26 November 2024 (REC reference: 24/SW/0128). Informed consent will be required for participation. Findings from the Cleft@18–23 study will be disseminated through peer-reviewed publications, conference presentations, newsletters, the study website (https://www.bristol.ac.uk/cleft18-23) and social media.

Despite growing evidence to characterise cancer-associated cognitive decline (CACD) in women with breast cancer, interventions to mitigate CACD are limited. Emerging evidence suggests aerobic exercise may enhance cognition after breast cancer diagnosis and treatment; yet, CACD remains an understudied outcome of exercise, and few high-quality studies have been conducted. In addition to knowledge gaps in effectiveness, the translation of exercise interventions to community settings remains challenging. The Breast cancer Reasoning and Activity INtervention (BRAIN) investigates the effectiveness of aerobic exercise training, delivered in a community-based setting, for improving cognitive function in women with breast cancer and gathers information on the implementation success of the intervention.

This Hybrid Type I effectiveness–implementation study is conducted at an academic medical centre in the southwestern United States in partnership with a non-profit, community health and wellness organisation. The study enrols 160 women diagnosed with stage I–IIIa breast cancer and within 3–36 months of treatment completion into a 1:1 randomised controlled trial. Individuals randomised to the exercise group receive a 6-month, individually tailored aerobic exercise programme delivered by exercise trainers employed at local community fitness centres. The programme is progressive in nature and designed to help participants achieve aerobic exercise levels consistent with guidelines for cancer survivors. Individuals randomise to the control group receive a 6-month health education control intervention delivered virtually by hospital-based health educators. Cognitive performance (primary), self-reported cognition, patient-reported outcomes, physical activity and cardiorespiratory fitness are measured at baseline, 6 months (postintervention) and 12 months (follow-up). Brain structure and function are measured via magnetic resonance imaging (MRI) at baseline and 6 months. Implementation outcomes are defined by the RE-AIM framework, which includes reach, effectiveness, adoption, implementation and maintenance. RE-AIM outcomes are measured at baseline, 6 months, 12 months and ongoing during the study.

This study was approved by the Mayo Clinic Institutional Review Board (#23-000020). All participants provide informed consent prior to participation. Findings will be disseminated to scientific, clinical and community audiences through manuscripts, presentations and newsletters.
