Interpersonal cognitive distortions as mediators of the relationship between psychological distress and nomophobia in adolescents: a cross-sectional mediation analysis.

The increasing reliance on smartphones for emotional relief and social connectivity has contributed to the rise of nomophobia. The present study examined interpersonal cognitive distortions (ICDs) as mediators of the relationship between psychological distress and nomophobia in adolescents using a cross-sectional mediation design. A sample of 500 adolescents completed standardized measures assessing psychological distress (DASS-21), nomophobia (NMP-Q), and interpersonal cognitive distortions. To examine the hypothesized mechanisms through which psychological distress influences nomophobia, a p…

Technology Acceptance Among Low-Income Asian American Older Adults: Cross-Sectional Survey Analysis.

BACKGROUND: Studies show that the use of information and communications technologies (ICTs), including smartphones, tablets, computers, and the internet, varies by demographic factors such as age, gender, and educational attainment. However, the connections between ICT use and factors such as ethnicity and English proficiency, especially among Asian American older adults, remain less explored. The technology acceptance model (TAM) suggests that 2 key attitudinal factors, perceived usefulness (PU) and perceived ease of use (PEOU), influence technology acceptance. While the TAM has been adapted …

Measurement of Human Walking Movements by Using a Mobile Health App: Motion Sensor Data Analysis.

BACKGROUND: This study presents a new approach to measure and analyze the walking balance of humans by collecting motion sensor data in a smartphone. OBJECTIVE: We aimed to develop a mobile health (mHealth) app that can measure the walking movements of human individuals and analyze the differences in the walking movements of different individuals based on their health conditions.

Machine learning for scalable obstructive sleep apnea risk screening using digital phenotyping from wearable devices and clinical scales.

Obstructive sleep apnea (OSA) is common yet frequently underdiagnosed, partly because overnight polysomnography (PSG) is logistically burdensome and access to specialized testing is limited. We aimed to develop machine-learning models for OSA risk screening using multimodal digital phenotyping from consumer-grade wearable devices, smartphone-based assessments, and clinical scales. We enrolled 338 participants and collected data over four weeks. After preprocessing, 107 features were derived from wearable-derived physiological and activity measures, smartphone-based records, and questionnaire-b…

DP-MDLA Net: Detection of smooth pursuit abnormalities in Parkinson's disease.

OBJECTIVES: To develop and validate a smartphone video-based framework using deep learning for quantifying smooth-pursuit abnormalities in Parkinson's disease. METHODS: Smartphone videos (N = 54) from 18 patients with confirmed Parkinson's disease were rigorously annotated to identify 1767 event-level samples (2-second windows), comprising 941 normal and 826 abnormal smooth-pursuit events. Ocular landmarks were extracted using MediaPipe FaceLandmarker. Preprocessing steps included canthus-referenced spatial normalization, Kalman smoothing, and blink filtering.

Evaluation of a digital stethoscope for electrocardiographic recording in donkeys: Preliminary results.

The digital stethoscope (DS) is a cost-effective single-lead digital stethoscope that allows simultaneous electrocardiographic (ECG) and phonocardiographic recordings on a smartphone. Despite its application in small animals and horses, there are currently no studies on its use in donkeys. The aim of this study was to evaluate the use of a new smartphone-based DS device in recording ECG tracings in donkeys. Standard base-apex lead ECG (sECG) and single-lead DS ECG (dECG) were simultaneously recorded for at least 30 s. Both sECG and dECG tracings were analysed by the same operator, recording he…

Modifiable dementia risk factors associated with objective and subjective cognition.

INTRODUCTION: Early detection of both objective and subjective cognitive impairment is important. Subjective complaints in healthy individuals can precede objective deficits. However, the differential associations of objective and subjective cognition with modifiable dementia risk factors are unclear. METHODS: We gathered a large cross-sectional sample (N = 3327, age 18 to 84) via a smartphone app and quantified the associations of 13 risk factors with subjective memory problems and three objective measures of executive function (visual working memory, cognitive flexibility, model-based plann…

Biomimetic mineralization-based In situ growth of AuNCs@ZIF-8 on paper fibers for visual detection of copper ions.

As one of the essential trace elements in life activities, copper ion (Cu2+) plays a very important role in human health. However, copper-containing pesticides are usually used for sterilization and disinfestation in agriculture. Thus, the residues of copper-containing pesticides in agricultural samples increase the risk of excessive intake of Cu2+ for human. The development of an effective method for detecting Cu2+ is still an important task. Herein, a detecting system based on AuNCs@ZIF-8 modified paper and smartphone platform was developed for visual detection of Cu2+ in agricultural sample…
