AI Article Synopsis
- The study explores how irregular sleep patterns due to circadian rhythm sleep loss affect motor inhibition and execution, particularly through a pointing task over 30 days.
- Participants performed a regular tapping task and a countermanding task where they had to stop their current action, with one group following a normal sleep schedule and the other group experiencing irregular hours.
- Results showed that the group with disrupted sleep had more difficulty with inhibitory control (like stopping actions) but had quicker movement times in regular tasks, highlighting that irregular sleep mainly impacts the ability to inhibit actions rather than overall motor execution.
Article Abstract
Under total sleep deprivation, both inhibitory and motor control are impaired. However, how circadian rhythm sleep loss caused by irregular sleep pattern affects motor inhibition and execution in continuous actions remains unknown. This study utilized a pointing task to investigate the question over 30 days. During regular trials, participants were instructed to tap on a specified location, while in countermanding trials, they were required to countermand their current action. Additionally, there was a control group performed the same task following a normal 24-h rhythm. The results indicated that the decrease in accuracy and the increase in movement time in countermanding trials were more prominent in the shift work group. In contrast, there was no significant difference in reaction time between the two groups. Notably, the shift work group outperformed the control group in terms of movement time in regular trials and radial displacement in countermanding trials. Overall, these results show that circadian rhythm sleep loss predominantly affects inhibitory control, rather than motor control, underscoring the nuanced impacts of sleep disruption on differential aspects of cognitive and motor functions.

Purpose: Chronic jet lag (CJL) is known to disrupt circadian rhythms, which regulate various physiological processes, including ocular surface homeostasis. However, the specific effects of CJL on lacrimal gland function and the underlying cellular mechanisms remain poorly understood.
Methods: A CJL model was established using C57BL/6J mice.

This study aimed to investigate sleep quality, chronotype preferences, anxiety, and depression levels in patients diagnosed with acne vulgaris and compare them with healthy controls. This cross-sectional case-control study included 92 patients with acne vulgaris and 59 age- and sex-matched healthy controls. Acne severity was assessed using the Global Acne Grading System (GAGS); sleep quality using the Pittsburgh Sleep Quality Index (PSQI); chronotype preferences using the Morningness-Eveningness Questionnaire (MEQ); and anxiety and depression levels using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI).

Sleep-wake disturbances frequently present in Veterans with mild traumatic brain injury (mTBI). These TBI-related sleep impairments confer significant burden and commonly exacerbate other functional impairments. Therapies to improve sleep following mTBI are limited and studies in Veterans are even more scarce.

Fatigue can cause human error, which is the main cause of accidents. In this study, the dynamic fatigue recognition of unmanned electric locomotive operators under high-altitude, cold and low oxygen conditions was studied by combining physiological signals and multi-index information. The characteristic data from the physiological signals (ECG, EMG and EM) of 15 driverless electric locomotive operators were tracked and tested continuously in the field for 2 h, and a dynamic fatigue state evaluation model based on a first-order hidden Markov (HMM) dynamic Bayesian network was established.

Background: Digital wearable devices, worn on or close to the body, have potential for passively detecting mental and physical health symptoms among people with severe mental illness (SMI); however, the roles of consumer-grade devices are not well understood.
Objective: This study aims to examine the utility of data from consumer-grade, digital, wearable devices (including smartphones or wrist-worn devices) for remotely monitoring or predicting changes in mental or physical health among adults with schizophrenia or bipolar disorder. Studies were included that passively collected physiological data (including sleep duration, heart rate, sleep and wake patterns, or physical activity) for at least 3 days.
