The PASTDUe Nutrition Ecosystem Project (PASTDUe)

This is a research study to determine if a particular method of providing nutrition improves the clinical outcomes of patients in the intensive care unit (ICU) who have undergone abdominal surgery and would require nutrition delivered via the bloodstream (called total parenteral nutrition or TPN). The nutrition method we are testing is a structured nutrition delivery plan that involves tube feeding, oral nutrition supplements, and the use of a device (called an indirect calorimeter or IC) to measure calorie needs. This study will also use two devices to measure fat and muscle mass to examine changes during hospitalization. Subjects will be followed throughout hospitalization where nutrition status and fat and muscle mass will be closely monitored. Study activities will begin within 72 hours of a patient's abdominal surgery. TPN (total parenteral nutrition, a method of feeding that bypasses the usual process of eating and digestion) will be started, a non-invasive method of assessing calorie needs (indirect calorimetry (IC)) will be started, a urine sample will be collected to help assist in protein needs, and fat/muscle mass will be measured using bioelectrical impedance analysis (BIA), and an ultrasound. This is a minimal risk study and all products/devices used are non-invasive and FDA-approved. Indirect calorimetry and urine sample collection will be conducted every 3 days during the stay in the Intensive Care Unit - ICU, then every 5 days until hospital discharge. BIA and muscle ultrasound will be conducted every 7 days during ICU stay, then every 14 days until hospital discharge.

Personalized Nutrition to Improve Recovery in Trauma

The purpose of this study is to determine if a particular method of providing nutrition improves the outcomes of patients in the intensive care unit (ICU) who have undergone abdominal surgery following trauma and would require nutrition delivered via the bloodstream (called total parenteral nutrition or TPN). The nutrition method being tested is a structured nutrition delivery plan, called the SeND Home pathway, that involves TPN, oral nutrition supplements, and the use of a device (called an indirect calorimeter or IC) to measure calorie needs. Participants will be randomly assigned (like the flip of a coin) to the SeND Home program or standard of care nutrition. In the SeND Home program, participants will receive TPN, followed by oral nutrition supplements (shakes) for 4 weeks after discharge. The control group will follow standard of care nutrition delivery that begins during ICU stay and concludes at hospital discharge. Participants in both groups will undergo non-invasive tests that measure how much energy (calories) they are using, body composition, and muscle mass and complete walking and strength tests, and surveys about quality of life.

Clinical Outcomes of Non-Indicated Staged Laparotomies in Abdominal Trauma

The goal of this observational study is to understand how often staged operations are performed in abdominal trauma patients without meeting standard clinical criteria, and to explore related clinical characteristics and outcomes. The main questions it aims to answer are: How frequently are staged operations performed when not clinically indicated? What are the clinical features and outcomes of patients who undergo non-indicated staged operations? What are the risk factors for delayed reoperation among patients who initially received a single operation? Researchers will review medical records of patients who underwent exploratory laparotomy for abdominal trauma at Far Eastern Memorial Hospital between January 1, 2013, and December 31, 2024. Participants will be grouped based on whether they had a single or staged operation, and whether their initial operation met established criteria for a staged approach. Clinical characteristics and outcomes will be compared across groups.

Phased-Array Versus Curvilinear Probe for FAST Ultrasonography

Background: FAST ultrasound is a crucial technique in emergency medicine, enabling rapid assessment of trauma patients. By allowing visualization of an effusion in a trauma patient in a far more sensitive and specific way than clinical examination, it enables informed decisions to be made on therapeutics, technical gestures, but also the potential receiving service. Arbitrarily, FAST ultrasound is taught with the cardiac probe (phased-array) and the abdominal probe (curvilinear). The difference in use of these two probes varies according to operator and team, with no figures available. No recent study has been conducted on the possibility of better diagnostic performance of FAST with a curvilinear versus phased-array probe. Objective: The main objective of this project is to evaluate and compare the diagnostic performance of FAST ultrasound using a phased-array probe versus a curvilinear probe in the detection of effusions in trauma patients (FAST protocol). Materials and methods: Prospective, interventional, multicenter, randomized study. Hypothesis tested: FAST-ultrasound with a curvilinear probe improves diagnostic performance compared with FAST-ultrasound with a phased-array probe.

The PseAn Study - Study Protocol

The researchers aim to study the role of contrast ultrasound in detecting post-traumatic splenic, hepatic, and renal PAs compared with the gold standard of CT with intravenous contrast at different follow-up time points, and whether it can replace CT scan in the follow-up of solid organ injuries
