Article Abstract
Background: Multiple system atrophy (MSA) is a progressive neurodegenerative disorder with diverse symptoms that complicate diagnosis. We aimed to characterize MSA-related symptoms, medications, and healthcare resource utilization (HCRU).
Research Design And Methods: This retrospective cohort study used a large US claims database. Newly diagnosed patients >30 years old with ≥2 MSA diagnosis (2017 - 2021) were matched to controls. Endpoints related to MSA symptoms, prescriptions, and HCRU were compared between the two groups during the first year after diagnosis. Conditional logistic regression models examined the association between each outcome and MSA.
Results: A total of 1187 MSA patients and 4748 matched-controls were compared. MSA patients had significantly higher rates of various symptoms, respectively (OR and 95% CI): orthostatic hypotension (38.7% and 0.8%; 89.6, 57.3 - 140.2); memory disorders (22.4% and 3.6%; 9.2, 7.3 - 11.6); motor symptoms (78.1% and 33.1%; 7.5, 6.4 - 8.7); falls (11.1% and 2.2%; 6.4, 4.8 - 8.5); fatigue (46.6% and 13.6%; 5.8, 5.0 - 6.7); mood disorder (62.3% and 24.2%; 5.5, 4.8 - 6.4); and urinary dysfunction (30.8% and 9.1%; 4.9, 4.1 - 5.8), among other. They also received more medications for these conditions and had higher rates of hospitalizations and other HCRU.
Conclusions: This real-world study of MSA-related symptoms, treatments, and HCRU demonstrates the significant disease burden associated with MSA.

Measuring alignment between the ADRC UDS data elements, FDA, and EHR data standards.
Alzheimers Dement
September 2025
Department of Population Health Sciences, University of Texas Health Science Center at San Antonio, San Antonio, Texas, USA.
Introduction: We compared and measured alignment between the Health Level Seven (HL7) Fast Healthcare Interoperability Resources (FHIR) standard used by electronic health records (EHRs), the Clinical Data Interchange Standards Consortium (CDISC) standards used by industry, and the Uniform Data Set (UDS) used by the Alzheimer's Disease Research Centers (ADRCs).
Methods: The ADRC UDS, consisting of 5959 data elements across eleven packets, was mapped to FHIR and CDISC standards by two independent mappers, with discrepancies adjudicated by experts.
Results: Forty-five percent of the 5959 UDS data elements mapped to the FHIR standard, indicating possible electronic obtainment from EHRs.
The burden of dengue fever in travellers: a systematic literature review.
New Microbes New Infect

Takeda Pharmaceuticals International AG, Zurich, Switzerland.
Background: Dengue is a mosquito-borne viral infection with growing global impact, including international travellers travelling to and from endemic regions. This systematic literature review aimed to assess the clinical and economic burden of dengue in travellers from non-endemic countries.
Methods: This systematic review was conducted following the PRISMA guidelines to assess the incidence, prevalence, mortality, healthcare resource use, and costs of dengue fever in travellers between non-endemic and endemic regions.

Introduction: Spinal cord injury (SCI) presents a significant burden to patients, families, and the healthcare system. The ability to accurately predict functional outcomes for SCI patients is essential for optimizing rehabilitation strategies, guiding patient and family decision making, and improving patient care.
Methods: We conducted a retrospective analysis of 589 SCI patients admitted to a single acute rehabilitation facility and used the dataset to train advanced machine learning algorithms to predict patients' rehabilitation outcomes.

Department of Physical Therapy, Temerty Faculty of Medicine, University of Toronto, Toronto, ON, Canada.
Introduction: Online community-based exercise (CBE) is a rehabilitation strategy that can promote health outcomes among people living with HIV. We aimed to describe experiences implementing a community-based exercise (CBE) intervention with adults living with HIV.
Methods: We conducted a longitudinal qualitative descriptive study involving interviews with adults living with HIV and persons implementing an online tele-coaching CBE intervention.
Background: Transforming Clinical Practice Guideline (CPG) recommendations into computer readable language is a complex and ongoing process that requires significant resources, including time, expertise, and funds. The objective is to provide an extension of the widely used GIN-McMaster Guideline Development Checklist (GDC) and Tool for the development of computable guidelines (CGs).
Methods: Based on an outcome from the Human Centered Design (HCD) workshop hosted by the Guidelines International Network North America (GIN-NA), a team was formed to develop the checklist extension.
