Deep-learning Based Location of Spine CT

CT-guided epidural steroid injection (ESI) thrives among interventional radiologists. Although X-ray fluoroscopy still remains as the gold standard to guide ESI, CT guidance has the merits of accurate location of needle tip and relatively low radiation doses with intermittent mode. However, it is time-consuming for doctors to select the optimal plane for needle placement and manually segment spinal structures. The main of the study is to automatically identify the optimal plane...

Analyze Sleep Stages by Portable ECG Device

Sleep is a fundamental need for human and is associated with the working performance and the disease occurrence. Furthermore, the amount of people with sleep disorder or apnea increased largely. Thus, the analysis of sleep stages and the measurement of sleep quality became more important recently. In clinical settings, the analysis of daily sleep quality depends on actigraphy and sleep log. However, the uses of actigraphy and sleep log are not really convenient for patients. In...

Sleep-dependent Learning in Aging

The specific objective of this proposed research is to understand whether deficits in sleep-dependent memory changes reflect age-related changes in sleep, memory, or both. The central hypothesis is that changes in both memory and sleep contribute to age-related changes in sleep-dependent memory processing. To this end, the investigators will investigate changes in learning following intervals of sleep (overnight and nap) and wake in young and older adults.

Sleep Apnoea in Haemodialysis

Sleep disturbance is a significant issue in people undergoing dialysis. More than 80% of haemodialysis patients complain of difficulty sleeping. Inadequate sleep can cause poor daytime function and increased risk of motor vehicle incidents. One of the common reasons for sleep disturbance in dialysis patients is sleep apnoea. Sleep apnoea involves pauses in breathing that occur during sleep. Each pause can last only a few seconds or minutes. Severe sleep apnoea reduces oxygen s...

Effects of Eszopiclone on Sleep-dependent Learning in Schizophrenia

This study will determine whether eszopiclone will normalize sleep patterns and restore sleep-dependent enhancement of motor skill learning in patients with schizophrenia. The investigators will compare subjects taking a placebo to those taking 3 mg of eszopiclone with regard to: sleep architecture and sleep latency as measured by actigraphy and polysomnography and sleep-dependent motor skill learning.

Set Your Goal: Engaging Go/No-Go Active Learning

Role of Sleep in Cardiovascular Functions

Sleep and particularly deep sleep are playing an important role for brain and body health. Poor sleep has been associated with risk factors for cardiovascular disease and moreover, is hypothesized to increased mortality risk of cardiovascular diseases. Yet, the role of specific sleep processes for cardiovascular function remains unclear. Particularly deep sleep, which is manifested by large amplitude, low frequency oscillations is of importance for the restorative functions of ...

Diagnostic Performance of Deep Learning for Angle Closre

Primary angle closure diseases (PACD) are commonly seen in Asia. In clinical practice, gonioscopy is the gold standard for angle width classification in PACD patietns. However, gonioscopy is a contact examination and needs a long learning curve. Anterior segment optical coherence tomography (AS-OCT) is a non-contact test which can obtain three dimensional images of the anterior segment within seconds. Therefore, we designed the study to verify if AS-OCT based deep learning algo...

Brain Maturation and Sleep

In this study, the investigator evaluates whether there are age-specific diurnal changes in markers of cortical plasticity in children, adolescents and adults. The question will be investigated by the quantification of brain metabolites and structural brain volumes using magnet resonance imaging (MRI) and electrophysiological markers using sleep encephalography (sleep EEG). In a second step, it will be tested how these markers of cortical plasticity change depending on a modula...

In addition obstruction patterns detected with AG are compared with DISE examination in the selected cases.

Multistate Relative Survival Model

Colorectal cancer (CRC) has high incidence and is associated with high case fatality. In France, the 5-year survival, pooled across all cancer stages at diagnosis, ranges from 57% in men to 60% in women. About one third of patients diagnosed with CRC will develop a metachronous recurrence during the following years. It is of paramount importance to accurately identify factors associated with the increased risk of progression and death, in order to develop effective follow-up an...

Sleep and Memory in Children

Sleep exerts a dual effect on learning: on the one hand, good sleep quality allows good daytime aptitudes leading to knowledge acquisition. On the other hand, sleep after learning is necessary for knowledge consolidation. A key role of sleep has clearly been demonstrated in memory consolidation in adults. Sleep leads to strengthen memory by promoting brain plasticity. Surprisingly, sleep influence on learning stabilization has scarcely been studied during childhood and in child...

This study examines extinction learning and extinction recall in youth with TS using an experimental task. This study will also explore the relationship between extinction processes (i.e., extinct...

Enhancement of Sleep With Wearables

Sleep, specifically deep sleep, plays a central role in healthy brain function, cardio-vascular processes, mood and quality of life. Auditory stimulation during one night of sleep has previously been shown to improve deep sleep and along with memory formation in both young and older adults. Yet, it remains unclear whether long-term auditory stimulation considerably improves sleep quality over longer time periods and how it affects daytime functioning such as cognition, mood, qu...
