Sociodemographic Differences in Respondent Preferences for Survey Formats: Sampling Bias and Potential Threats to External Validity

A United States-based patient-reported adult polyglucosan body disease registry: initial results

Background

Adult Polyglucosan Body Disease (APBD) is an ultra-rare, genetic neurodegenerative disorder caused by autosomal recessive mutations in the glycogen branching enzyme gene. Knowledge of the demographic and clinical characteristics of APBD patients and the natural history of the disease is lacking. We report here initial results from a patient-reported registry of APBD patients.

Objectives

(1) Maximize the quality of the APBD Registry survey data; (2) provide an initial report on APBD disease progression and natural history using these data; and (3) specify next steps in the process for testing potential new therapies.

Design

Data are from members of the APBD Research Foundation (New York), surveyed from 2014 by the Columbia APBD Patient/Family (CAP) Registry. Inclusion criteria are: disease onset at age 18+ and progressive clinical triad of peripheral neuropathy, spasticity, and neurogenic bladder.

Methods

Genetic testing results were used when available. Respondents found to not have APBD in clinical records were excluded. All changes and exclusions were recorded in a database edit log. Results are reported in frequency tables, bar graphs, time plots, and heat maps.

Results

The 96 respondents meeting inclusion criteria were predominantly (96.8%) White, highly educated (89.3% at least some college education), and mostly (85.1%) of Ashkenazi Jewish descent. 57.1% had at least one parent born in the United States, with at least one grandparent from Europe (excluding Russia; 75.4%), the United States (42.1%), or Russia (33.3%). 37.2% reported a family history of APBD, and 33.3% had an affected sibling. Median APBD onset age was 51 [Interquartile range (IQR) 11], and median age of diagnosis 57 (IQR 10.5). The 75 reported prior misdiagnoses were mainly peripheral neuropathy (43, 60.6%) and spinal stenosis (11, 15.1%).

Conclusion

Although from a demographically constricted survey, the results provide basic clinical information for future studies to develop treatments for APBD.

COVID-19: Factors Predicting Depressive Symptoms in People Aging With Long-Term Physical Disabilities

The mental health impact of the COVID-19 pandemic may be greater than that of the viral infection. This impact is likely greater for disadvantaged groups such as people with long-term physical disabilities (PwLTPD). This cross-sectional study used a multiple linear regression model to examine factors associated with depressive symptoms and to understand their relative importance during the onset of the COVID-19 pandemic. The model explained 58% of the variance in depressive symptoms. Anxiety was the most important predictor, accounting for 8% of variance. Higher levels of anxiety, loneliness, and financial stress; prior diagnosis of depression; and non-Black race predicted a higher level of depressive symptoms in PwLTPD during the onset of the COVID-19 pandemic. Occupational therapy practitioners should strategically acknowledge predictors of depression that cannot be modified and actively address those that can be modified through evidence-based interventions to improve depressive symptoms in PwLTPD.
