Purpose: The Vineland Adaptive Behavior Scale is often used in autism spectrum disorder (ASD) trials. The Adaptive Behavior Composite Score (VABS-ABC) is the standardized overall score (the average of the Socialization, Communication and Daily Living skills domains), and the standardized 2-Domain Composite Score (VABS-2DC) is a novel outcome measure (average of the Socialization and Communication domains). A within-person meaningful change threshold (MCT) has not been established for the VABS-2DC.

Purpose: To explore, from the perspective of Study Partners (SPs; eg, caregivers) of clinical trial participants with autism spectrum disorder (ASD), any changes experienced in socialization and communication over the clinical trial, how these changes manifested, and the impact these changes had on the autistic individual, the SP, and family. This helps interpret whether changes in trial outcomes were meaningful.

Patients And Methods: Interviews were conducted with the SPs of individuals with ASD, without intellectual disability, from 2 clinical trials: 86 children (aged 5-12 years) or adolescents (aged 13-17 years) who took part in the aV1ation trial (83.

Article Synopsis
  • Studies show that up to 50% of variation in complex traits among genetically identical individuals is unexplained by genetics or environment.
  • Researchers discovered that a protein called neuronatin (NNAT) helps protect against this unexplained variation, as seen in mice with NNAT deficiencies that exhibit abnormal growth patterns.
  • In humans, a pattern of unexplained variation closely resembles the findings in mice and is linked to changes in body composition and metabolic states, particularly concerning obesity and insulin response.

The search for rare variants in Alzheimer's disease (AD) is usually deemed a high-risk - high-reward situation. The challenges associated with this endeavor are real. Still, the application of genome-wide technologies to large numbers of cases and controls or to small, well-characterized families has started to be fruitful.

Krabbe disease is an infantile neurodegenerative disorder resulting from pathogenic variants in the GALC gene that causes accumulation of the toxic sphingolipid psychosine. GALC variants are also associated with Lewy body diseases, an umbrella term for age-associated neurodegenerative diseases in which the protein α-synuclein aggregates into Lewy bodies. To explore whether α-synuclein in Krabbe disease has pathological similarities to that in Lewy body disease, we performed an observational post-mortem study of Krabbe disease brain tissue (n = 4) compared to infant controls (n = 4) and identified widespread accumulations of α-synuclein.

Background: The factors typically considered to be associated with Dupuytren disease have been described, such as those in the "Dupuytren diathesis." However, the quality of studies describing them has not been appraised. This systematic review aimed to analyze the evidence for all factors investigated for potential association with the development, progression, outcome of treatment, or recurrence of Dupuytren disease.

Background: Patient-reported outcomes measures (PROMs) assess a patient's subjective appraisal of health outcomes from their own perspective. Despite hypothesised benefits that feedback  on PROMs can support decision-making in clinical practice and improve outcomes, there is uncertainty surrounding the effectiveness of PROMs feedback.

Objectives: To assess the effects of PROMs feedback to patients, or healthcare workers, or both on patient-reported health outcomes and processes of care.

Background: One way in which care for pregnant and postpartum women living with long-term health conditions (LTCs) may be improved is through the adoption of standardised measures to provide evidence of health outcomes and wellbeing from the woman's perspective.

Aim: The study explores the views of pregnant and postpartum women living with LTCs, and healthcare professionals to better understand the potential value of using standardised health and wellbeing measures within this patient population.

Methods: Qualitative semi-structured telephone interviews were conducted to explore the perceived value of using measures with pregnant and postpartum women living with LTCs within maternity services.

Importance: International efforts are being made towards a person-centred care (PCC) model, but there are currently no standardised mechanisms to measure and monitor PCC at a healthcare system level. The use of metrics to measure PCC can help to drive the changes needed to improve the quality of healthcare that is person centred.

Objective: To develop and validate person-centred care quality indicators (PC-QIs) measuring PCC at a healthcare system level through a synthesis of the evidence and a person-centred consensus approach to ensure the PC-QIs reflect what matters most to people in their care.

The SNCA locus currently has an indisputable role in Parkinson's disease and other synucleinopathies. The role of genetic variability in the other members of the synuclein family (SNCB and SNCG) in disease is far less clear. In this review, we critically assess the pathogenicity, main characteristics, and roles of genetic variants in these genes reported to be causative of synucleinopathies.

Frontotemporal dementia (FTD), dementia with Lewy bodies (DLB) and vascular dementia (VaD) are the most common forms of dementia after Alzheimer's disease (AD). The heterogeneity of these disorders and/or the clinical overlap with other diseases hinder the study of their genetic components. Even though Mendelian dementias are rare, the study of these forms of disease can have a significant impact in the lives of patients and families and have successfully brought to the fore many of the genes currently known to be involved in FTD and VaD, starting to give us a glimpse of the molecular mechanisms underlying these phenotypes.

Value-based health care is increasingly promoted as a strategy for improving care quality by benchmarking outcomes that matter to patients relative to the cost of obtaining those outcomes. To support the shift toward value-based health care in chronic kidney disease (CKD), the International Consortium for Health Outcomes Measurement (ICHOM) assembled an international working group of health professionals and patient representatives to develop a standardized minimum set of patient-centered outcomes targeted for clinical use. The considered outcomes and patient-reported outcome measures were generated from systematic literature reviews.

Background: In this paper, we report the findings of a realist synthesis that aimed to understand how and in what circumstances patient reported outcome measures (PROMs) support patient-clinician communication and subsequent care processes and outcomes in clinical care. We tested two overarching programme theories: (1) PROMs completion prompts a process of self-reflection and supports patients to raise issues with clinicians and (2) PROMs scores raise clinicians' awareness of patients' problems and prompts discussion and action. We examined how the structure of the PROM and care context shaped the ways in which PROMs support clinician-patient communication and subsequent care processes.
