Laptop computers are an uncommon source of burns to the thighs and perineum. Burns can result from the prolonged contact of hot surfaces at the base of the computer with the user's lap. The authors report a case of second-degree burns to the thigh of an otherwise healthy patient that resulted from prolonged use of the laptop. We measured the temperatures of the patient's computer and the temperatures of other popular laptop computers. Laptops can develop temperatures that can pose a risk for burns if the skin is exposed for prolonged periods of time. Patients with impaired lower extremity sensation, altered consciousness, or decreased mobility are at higher risk for laptop burns. To their knowledge, this is the first case report of such a burn injury in the American literature.

Objective: Depression among older adults is increasingly becoming a global public health issue. Along with the rapid development of digital information technology, the Internet has profoundly changed the lifestyle of older adults. However, few studies have focused on the mental health of rural middle-aged and older adult populations, and this study aims to explore the impact of Internet use on depressive symptoms among rural middle-aged and older adults.

Background: Although evening screen time is thought to impair subsequent sleep, current measures are limited to questionnaires which seem unlikely to accurately assess screen time in youth. Given the ubiquitous nature of digital devices, improving measurement of screen time is required before related health effects can be appropriately determined. The aim of this study was to objectively quantify screen time before sleep using video camera footage.

Background: This study aims to determine the impact of laptop and tablet use on total motile sperm count (TMSC) in men being investigated for assisted reproduction.
Methods: A cross-sectional study was conducted on 156 men attending a fertility clinic in Jamaica. Routine semen analyses were performed and parameters specific to TMSC assessed.
Cross-device and test-retest reliability of speech acoustic measurements derived from consumer-grade mobile recording devices.

In recent years, there has been growing interest in remote speech assessment through automated speech acoustic analysis. While the reliability of widely used features has been validated in professional recording settings, it remains unclear how the heterogeneity of consumer-grade recording devices, commonly used in nonclinical settings, impacts the reliability of these measurements. To address this issue, we systematically investigated the cross-device and test-retest reliability of classical speech acoustic measurements in a sample of healthy Chinese adults using consumer-grade equipment across three popular speech tasks: sustained phonation (SP), diadochokinesis (DDK), and picture description (PicD).
