abstract = {Speech is known to carry health-related attributes, which has emerged as a novel venue for remote and long-term health monitoring. However, existing models are usually tailored for a specific type of disease, and have been shown to lack generalizability across datasets. Furthermore, concerns have been raised recently towards the leakage of speaker identity from health embeddings. To mitigate these limitations, we propose WavRx, a speech health diagnostics model that captures the respiration and articulation related dynamics from a universal speech representation. Our in-domain and cross-domain experiments on six pathological speech datasets demonstrate WavRx as a new state-of-the-art health diagnostic model. Furthermore, we show that the amount of speaker identity entailed in the WavRx health embeddings is significantly reduced without extra guidance during training. An in-depth analysis of the model was performed, thus providing physiological interpretation of its improved generalizability and privacy-preserving ability. © 2013 IEEE.},

abstract = {Purpose: After metabolic and bariatric surgery (MBS), many patients have excess skin (ES), which can cause inconveniences. Identifying factors related to ES quantity and inconveniences is crucial to inform interventions. The aim of this study was to identify sociodemographic, physical, psychosocial, and behavioral factors associated with ES quantity and inconveniences. Materials and Methods: A mixed-method study with a sequential explanatory design was conducted with 124 adults (92% women, M age 46.5 ± 9.9 years, M time post-MBS 34.2 ± 27.6 months). During phase I, ES quantity (arms, abdomen, thighs) and inconveniences and sociodemographic, anthropometric, clinical, and behavioral outcomes were assessed. In phase II, 7 focus groups were performed with 37 participants from phase I. A triangulation protocol was completed to identify convergences, complementarities, and dissonances from quantitative and qualitative data. Results: Quantitative data indicate only ES quantity on arms was associated with ES inconveniences on arms (r =.36, p <.01). Total ES quantity was associated with maximal body mass index (BMI) reached pre-MBS (r =.48, p <.05) and current BMI (r =.35, p <.05). Greater ES inconvenience was associated with higher social physique anxiety and age (R 2 =.50, p <.01). Qualitative data were summarized into 4 themes: psychosocial experiences living with ES, physical ailments due to ES, essential support and unmet needs, and beliefs of ES quantity causes. Conclusion: Measured ES quantity is related to higher BMI, but not reported inconveniences. Greater self-reported ES quantity and inconveniences were associated with body image concerns.
