Post-acute sequelae of SARS-CoV-2 (PASC) is defined as persistent symptoms after apparent recovery from acute COVID-19 infection, also known long-haul. We performed a retrospective review electronic health records (EHR) the University California COvid Research Data Set (UC CORDS), de-identified EHR PCR-confirmed SARS-CoV-2-positive patients in California. The purposes were to (1) describe prevalence PASC, (2) and symptom clusters, (3) identify risk factors for PASC. subjected non-negative...
Abstract Emerging data suggest that the effects of infection with SARS-CoV-2 are far reaching extending beyond those severe acute disease. Specifically, presence persistent symptoms after apparent resolution from COVID-19 have frequently been reported throughout pandemic by individuals labeled as “long-haulers”. The purpose this study was to assess for at days 0-10 and 61+ among subjects PCR-confirmed infection. University California COvid Research Data Set (UC CORDS) used identify 1407...
Online social networks play a major role in modern societies, and they have shaped the way relationships evolve. Link prediction has many potential applications such as recommending new items to users, friendship suggestion discovering spurious connections. Many real evolve connections multiple layers (e.g. networking platforms). In this article, we study link problem multiplex networks. As an example, consider network of Twitter (as microblogging service) Foursquare location-based network)....
Background Assessment of sleep quality is essential to address poor and understand changes. Owing the advances in Internet Things wearable technologies, monitoring under free-living conditions has become feasible practicable. Smart rings smartwatches can be employed perform mid- or long-term home-based monitoring. However, validity such wearables should investigated terms parameters. Sleep validation studies are mostly limited short-term laboratory tests; there a need for study assess...
Technology enables the continuous monitoring of personal health parameter data during pregnancy regardless disruption normal daily life patterns. Our research group has established a project investigating usefulness an Internet Things-based system and smartwatch technology for women to explore variations in stress, physical activity sleep. The aim this study was examine patterns well-being pregnant before national stay-at-home restrictions related COVID-19 pandemic Finland.A longitudinal...
Physiological response is an automatic reaction that triggers a physical to stimulus such as stress, emotion, pain, etc. Examples include changes in heart rate, respiration, perspiration, and eye pupil dilation. Electrodermal Activity (EDA), also known Galvanic Skin Response (GSR), measures perspiration by detecting the electrical conductivity of skin. Previous studies have already shown EDA one leading indicators for stimulus. However, signal itself not trivial analyze. To detect different...
Continuous monitoring of blood pressure (BP) can help individuals manage their chronic diseases such as hypertension, requiring non-invasive measurement methods in free-living conditions. Recent approaches fuse Photoplethys-mograph (PPG) and electrocardiographic (ECG) signals using different machine deep learning to non-invasively estimate BP; however, they fail reconstruct the complete signal, leading less accurate models. In this paper, we propose a cycle generative adversarial network...
The stress detection problem is receiving great attention in related research communities. This due to its essential part behavioral studies for many serious health problems and physical illnesses. There are different methods algorithms using physiological signals. Previous have already shown that Galvanic Skin Response (GSR), also known as Electrodermal Activity (EDA), one of the leading indicators stress. However, GSR signal itself not trivial analyze. Different features extracted from...
The world has been affected by COVID-19 coronavirus. At the time of this study, number infected people in United States is highest globally (31.2 million infections). Within population, patients diagnosed with acute respiratory distress syndrome (ARDS) are more life-threatening circumstances, resulting severe system failure. Various studies have investigated infections to and ARDS monitoring laboratory metrics symptoms. Unfortunately, these methods merely limited clinical settings,...
The COVID-19 pandemic has affected virtually every region in the world. At time of this study, number daily new cases United States was greater than that any other country, and trend increasing most states. Google Trends provides data regarding public interest various topics during different periods. Analyzing these trends using mining methods may provide useful insights observations outbreak.The objective study is to consider predictive ability search terms not directly related with regard...
