Studies during the COVID-19 pandemic showed that children had heightened nasal innate immune responses compared with adults. To evaluate role of viruses and bacteria in driving these responses, we performed cytokine profiling comprehensive, symptom-agnostic testing for respiratory bacterial pathobionts nasopharyngeal samples from tested SARS-CoV-2 2021-22 (n = 467). Respiratory and/or were highly prevalent (82% symptomatic 30% asymptomatic children; 90 49% <5 years). Virus detection load...

Background and Objectives: Prior research has successfully identified linguistic behavioral patterns associated with schizophrenia spectrum disorders (SSD) from user generated social media activity. Few studies, however, have explored the potential for image analysis to inform psychiatric care individuals SSD. Given popularity of image-based platforms, such as Instagram, investigating data could further strengthen associations between activity health. Methods: We collected 11,947 Instagram...

Graphical representations of speech generate powerful computational measures related to psychosis. Previous studies have mostly relied on structural relations between words as the basis graph formation, i.e., connecting each word next in a sequence words. Here, we introduced method formation grounded semantic relationships by identifying elements that act upon other (action relation) and contents those actions (predication relation). Speech from picture descriptions open-ended narrative...

Wearable, sensor-equipped devices -- often referred to as wearables became increasingly public accessible during the last years. Health and fitness offer ubiquitous continuous sensing of various aspects our lives help us reflect learn about ourselves. The rising social acceptance body-worn technology is also a driver for increasing adoption on consumer level - especially healthcare sector booming [1]. Consumer surveys discovered that users expect them live longer happier [6].

Abstract Functional impairments contribute to poor quality of life in schizophrenia spectrum disorders (SSD). We sought (Objective I ) define the main functional phenotypes SSD, then II identify key biopsychosocial correlates, emphasizing interpretable data-driven methods. Objective was tested on independent samples: Dataset ( N = 282) and 317), with SSD participants who underwent assessment multiple functioning areas. Participants were clustered based functioning. evaluated by identifying...

Digital health technologies are increasingly being integrated into mental care. However, the adoption of these can be influenced by patients' digital literacy and attitudes, which may vary based on sociodemographic factors. This variability necessitates a better understanding patient attitudes to prevent divide, worsen existing care disparities.

Social cognitive impairments are core features of schizophrenia spectrum disorders (SSD) and associated with greater functional impairment decreased quality life. Metabolic disturbances have been related to in general neurocognition, but their relationship social cognition has not previously reported.

Fitness trackers not just provide easy means to acquire physiological data in real-world environments due affordable sensing technologies, they further offer opportunities for physiology-aware applications and studies HCI; however, their performance is well understood. In this paper, we report findings on the quality of 3 technologies: PPG-based wrist (Apple Watch, Microsoft Band 2), an ECG-belt (Polar H7) reference device with stick-on ECG electrodes (Nexus 10). We collected (heart rate,...

Sensing data from wearables have been extensively evaluated for fitness tracking, health monitoring or rehabilitation of individuals. However, we believe that wearable sensing can go beyond the individual and offer insights into social dynamics interactions with other users by considering multi-user data. In this work, present a new approach to using wrist-worn detection interaction features based on interpersonal synchrony - an transferable smart-watches trackers. We build up related work...

Health and fitness wearable technology has recently advanced, making it easier for an individual to monitor their behaviours. Previously self generated data interacts with the user motivate positive behaviour change, but issues arise when relating this long term mention of devices.

Summary Recent work indicates that heightened nasal innate immunity in children may impact SARS-CoV-2 pathogenesis. Here, we identified drivers of immune activation using cytokine profiling and multiplex pathogen detection 291 pediatric nasopharyngeal samples from the 2022 Omicron surge. Nasal viruses bacterial pathobionts were highly prevalent, especially younger (81% symptomatic 37% asymptomatic overall; 91% 62% subjects &lt;5 yrs). For SARS-CoV-2, viral load was highest young children,...
