The goal of this observational study is to develop a passive digital marker (PDM) for delirium severity and examine its performance in comparison to validated delirium severity tools in ICU patients \>50 years of age. The main questions it aims to answer are: * Is the trained convolutional neural network able to reliably measure delirium severity. * Is the Passive Digital Marker able to accurately measure delirium severity * Is the Passive Digital Marker acceptable and usable by frontline ICU nurse clinicians, patients, and their identified proxies (i.e., caregivers). Participants will: * Study participation involves a video camera recording you 24 hours per day while you are a patient in the Intensive Care Unit (ICU). * Study staff will visit you 4 times each day you are in the ICU. You will be asked questions each time they visit to train the digital marker and see differences between assessments and camera data. Read Less

This is a Phase Ia/Ib, two-part, randomized, placebo-controlled, double-blinded, first in human(FIH) study to evaluate the safety, tolerability, PK, and PD of ADEL-Y01 in healthy participants in Part 1 and participants with MCI due to AD and mild AD in Part 2. The study includes 2 parts: Part 1 (single ascending dose \[SAD\] and Part 2 (multiple ascending dose \[MAD\]). Read Less

This observational trial evaluates the use of Ommaya reservoir placed during a biopsy to collect biomarkers longitudinally in patients with brain tumor. A biomarker is a measurable indicator of the severity or presence of the disease state. An Ommaya reservoir is a small device that's implanted under the scalp. It allows the doctor to take samples of cerebrospinal fluid (CSF) in the future without doing a spinal tap. The identification of biomarkers in CSF is rapidly emerging as a promising minimally invasive approach for monitoring tumor growth and response to therapy. In the future, these biomarkers may be used to help determine what treatments could be most effective and how well a tumor has responded to prior therapy. Currently, limited long-term access to CSF has made it difficult for studies to learn if collecting CSF at different points in the treatment process is useful. Having an Ommaya reservoir placed during a biopsy may allow for longitudinal biomarker collection in patients with brain tumor. Read Less

It is sometimes difficult to precisely understand whether a primary liver cancer is a hepatocellular carcinoma or a cholangiocarcinoma. The researchers will develop and validate a liquid biopsy, based on exosomal content analysis and powered by machine learning, to help clinicians differentiate these two cancers before surgery.

To examine the relations between sleep (nap transitions, sleep physiology), memory, and brain development longitudinally, the researchers will assess n=180 children (in order to acquire n=152 usable data sets) who are 36-54 months of age and habitual nappers at enrollment. In each wave, the researchers will assess memory, memory change over a nap and equivalent waking interval, sleep physiology of the nap, and brain structure and function (using Magnetic Resonance Imagining or MRI). Additionally, overnight sleep physiology will be assessed in all participants. Waves will take place approximately every 6 months. For all children, three waves will be collected. With these data, the researchers will address the following aims: * Examine neural markers that predict the sleep transition (Aim 1); * Examine changes in sleep-dependent memory processing (mnemonic discrimination) over both nap and overnight sleep intervals, across the sleep transition (Aim 2); * Examine changes in sleep microstructure in both nap and overnight sleep across the sleep transition (Aim 3) * Examine interrelations among brain, memory and sleep microstructure across the sleep transition (Aim 4) Read Less

The goal of this clinical trial is to learn more about the interaction between a patient in the hospital and their treating doctor. A good relationship between patients and their doctors can help improve patient care. Doctors will be asked to use strategies to improve their interactions with patients in the hospital. The main questions it aims to answer are: * Will using the intervention strategies improve doctors' empathy towards their patients? * Will using the intervention strategies lead to improved scores in patient views of doctors' empathy? There will be 2 study arms. One group of doctors will be asked to use the intervention strategies. The other group of doctors will provide care as they would normally. Researchers will compare the doctors in the intervention arm to those in the control arm. Doctors are the primary subjects for this study. The doctors in both study arms will be asked to do the following: 1. Allow study staff to observe the interaction between them and their patients. 2. Complete a brief survey at the end of their 2-week work rotation. Doctors who are in the intervention arm will be asked to use suggested strategies when visiting with patients in the hospital. Patients are secondary subjects for this study. Patients of participating doctors may be asked to do the following: 1. Allow study staff to observe the interaction between them and their doctors. 2. Complete a brief survey after meeting with their doctor. Read Less

The primary aim of this study is to evaluate if a single bout of AM vs PM resistance exercise has different effects on insulin sensitivity and sleep. A randomized cross-over trial be used to compare resistance exercise at two different times of the day. Each condition will take place in a laboratory setting. Each condition will consist of exercise, overnight sleep, and oral glucose tolerance tests the following day. The AM exercise will occur \~1.5 hours after habitual wake, and PM exercise will occur \~11 hours after habitual wake. After a 2-6 week washout, participants will complete the other condition. The hypothesis is that PM exercise will be more beneficial than AM exercise in improving insulin sensitivity. This study could identify if there is a better time of day to perform resistance exercise to decrease risk of developing Type 2 Diabetes Mellitus. Read Less

The main goal of this study is to look at the performance of the neonatal, infant, and pediatric Philips SpO2 sensors with the Philips FAST Pulse Oximetry technology. Oxygen saturation measurements (SpO2) will be obtained via pulse oximetry and invasive arterial oxygen measurements (SaO2) will be obtained via arterial blood samples as part of your clinical care and assessed by co-oximetry. The study will aim to enroll a diverse population to help us understand the impact of skin pigmentation. Read Less

This study will utilize a quasi-experimental pre-test/post-test design and will be conducted on the medical and medical/surgical units at the VA Ann Arbor Healthcare System. Hospitalized patients on the intervention units will be offered the Inpatient Whole Health Bundle. This study will evaluate overall satisfaction with the hospital environment and care as well as the bundle and components using a mailed survey of patients discharged from each unit. This study will also conduct a qualitative assessment of the intervention to understand intervention experiences as well as barriers and facilitators to improving hospitalized patient well-being. Finally, the study will assess unit-level metrics. Read Less
