A retrospective cohort study will be conducted using a large administrative database of U.S. hospitals to understand the volume-outcome relationship among patients hospitalized with COVID-19.
This phase II trial tests how well ivonescimab before surgery works in treating patients with stage II-IV head and neck cancer that can be removed by surgery (resectable). Ivonescimab is a bispecific monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A bispecific monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens).
The goal of this research is to study a localization device for breast cancer called OneMark. This device will be studied in breast cancer surgery and during surveillance in patients being monitored for breast cancer. The main questions the study aims to answer are: Can surgeons visualize the OneMark device during breast cancer surgery better than a standard of care visualization device? Can radiologists visualize the OneMark device over time during breast cancer surveillance in patients with low or high density breast tissue? Participants will undergo breast cancer surgery or surveillance as required for their regular care. For patients undergoing surgery, the device will be implanted ahead of surgery. For patients in surveillance, the device will be implanted during biopsy and visibility of the device will be assessed by radiologists after 1, 3, and 6 months, and optionally after 12 months. Surgeons will complete a questionnaire at every surgery on the visibility of the OneMark device and the standard of care visualization device. Radiologists will complete a questionnaire after 1, 3, 6 months (and optionally after 12 months) after implantations in the patients in the surveillance program.
The primary purpose of this study is to conduct a clinical trial to test a prototype device for feasibility and not health outcomes. To do this, the investigators will evaluate the performance of commercially available inertial measurement unit sensors incorporated into an existing ankle brace ("sXAB") by TayCo Brace, Inc. We will compare the gait metrics calculated from the sensors incorporated into the brace with gold-standard equipment that is used in research and clinical settings to determine whether the sXAB performs adequately in terms of measurement or technical feasibility prior to further clinical evaluation. The sensors in the ankle brace will be validated in the lab, first on healthy subjects walking in standard tennis shoes/sneakers (protocol 1), and secondarily in the lab on healthy subjects wearing combat boots performing walking, running, jumping, and stair climbing (protocol 2). These movements were selected because they simulate key movements performed during operational activities. Protocol 1 will take place first, then aspects of the sXAB will be evaluated and implemented, then protocol 2 will take place. Participants completing protocol 1 are eligible to complete protocol 2. The study includes two cohorts of participants completing different functional tasks. All participants experience both conditions: with an ankle brace and without an ankle brace. Comparisons are made within-subject between brace and no-brace conditions. It is hypothesized that the sensor-enabled ankle brace will measure gait metrics with a high degree of accuracy (within 5%) when compared against the gold-standard lab equipment (i.e., motion capture and research-grade inertial measurement units).
This is a prospective, Phase IV, post-approval observational study evaluating postoperative outcomes in patients with a history of myopic corneal laser vision correction (LVC) undergoing bilateral cataract surgery with implantation of the CT LUCIA 621P intraocular lens (IOL). Up to 30 subjects (60 eyes) will be enrolled across up to three U.S. investigational sites. The study will assess visual and refractive outcomes, including biometry, manifest refraction, and patient-reported visual function over a 3-month follow-up period.
The purpose of this study is to assess the effect of quantitative block monitoring versus less expensive qualitative monitoring treatment effects on the lowest SpO2/FiO2 ratio in the PACU. The results will be incorporated into an enhanced recovery pathway for surgical patients.
The goal of this clinical trial is to learn if Lumitrace and the KARL STORZ POWER LED BLUE System can be used for anatomic visualization of the ureters in participants undergoing laparoscopic abdominopelvic surgery. The main questions it aims to answer are: * To evaluate the feasibility and clinical utility of Lumitrace to provide ureter visualization when used in tandem with the KARL STORZ POWER LED BLUE System during laparoscopic abdominopelvic surgery * To evaluate the safety and tolerability of a single intravenous dose of Lumitrace in participants undergoing laparoscopic abdominopelvic surgery Participants will participate in a Screening visit that will take place within 28 days of the scheduled administration of Lumitrace. Up to 10 participants will be enrolled and will receive a single intravenous 130 mg dose of Lumitrace. Within 30 minutes of injection, the ureter visualization will be captured by the KARL STORZ POWER LED BLUE System using white light and fluorescence and the surgeon will rate ureter visualization for each illumination mode based on qualitative Likert Scales. A safety follow-up visit will occur within 14 ±7 days of Lumitrace administration.
Purpose - This exploratory, split-wound study aims to evaluate the potential difference in skin reactions to two different types of sutures, dyed and undyed, used to close wounds after surgery. The study will assess whether dyed sutures to elicit increased tissue reactivity like redness, itching, and scarring and whether undyed sutures may be more optimal for wound healing and cosmetic response. Enrollment into the study and data collection is expected to take approximately 3-6 months. Follow-up visits will be chosen at 2 weeks, 4 weeks, and 3 months post-surgery, which is standard practice for monitoring healing and checking for complications such as infection or abnormal scarring. Primary Objective - The primary objective is to assess the response of wounds closed with both dyed and undyed sutures after cutaneous surgery to determine if there is a difference in wound healing and tissue reactivity with one compared to the other. Enrollment into the study and data collection is expected to take approximately 3-6 months. Follow-up visits will be chosen at 2 weeks, 4 weeks, and 3 months post-surgery, which is standard practice for monitoring healing and checking for complications such as infection or abnormal scarring.
The Goal of this Clinical Study is to evaluate the safety and effectiveness of the Rapidlink device in the repair or replacement of the supra-aortic vessels during open surgical repair of aortic disease affecting the thoracic aorta. This study will collect information on patients who are already having surgery to repair their aorta and who will have Rapidlink device implanted into one or more of the aortic arch vessels. The first 32 subjects enrolled will undergo left subclavian artery repair or replacement, only, with the Rapidlink device. After the 32nd subject, enrollment will proceed to include subjects undergoing any supra-aortic vessel (i.e., left subclavian artery, left common carotid artery, and/or innominate artery) repair or replacement with the Rapidlink device in a planned surgery. After the 32nd subject is enrolled in the main group, up to 30 subjects will undergo supra-aortic vessel (i.e., left subclavian artery, left common carotid artery, and/or innominate artery) repair or replacement with the Rapidlink device in an emergency setting. Data will be collected before, during and after surgery including recovery at discharge, 30 days, 6 months, 1 and 2 years after the surgery.

The purpose of the research study is to determine the overall clinical and radiographic outcome differences between internal brace technique and the gold standard Kirschner wires (K-wire) technique for treatment of perilunate dislocations (e.g. nonunion, reoperation, infection, fixation failure, etc.). A secondary purpose is to determine the specific types of complications and their incidence rates with respect to internal brace technique and the gold standard Kirschner wires (K-wire) technique (e.g. range of motion losses, pain, numbness, weakness, etc).
The goal of this randomized clinical trial is to compare opioid consumption among patients who receive a binary pain scale compared to those who receive a standard 10-point pain scale after undergoing anterior cruciate ligament (ACL) reconstruction surgery.
The purpose of this study is to determine if there is any difference with regard to complication rates for performing surgery on an operating room (OR) table vs performing surgery on a stretcher with a hand table. The OR table and the stretcher with a hand table are the two types of operative surfaces the investigators will compare. The aim of this study is to compare surgeries of finger, hand, wrist, forearm, and elbow. The investigators will conduct the research at two outpatient surgery centers and an inpatient hospital center to see if operating room surface and time of surgery has any effect on complications after surgery. The investigators also will compare the costs of the two types of operative surfaces for the surgery.
The purpose of this study is to describe the digital literacy of caregivers of pediatric surgical patients. The investigators hypothesize that caregivers of minority race, language of care other than English, and low neighborhood opportunity will have lower prevalence of digital literacy.
This prospective research study aims to see if pre-operative MRI can predict the margin status after transoral robotic surgery (TORS) for human papillomavirus positive (HPV+) tonsillar squamous cell carcinoma (SCC). The pre-operative MRI will have a standard MR neck without and with contrast, with added axial T2 weighted sequence and T2 SPACE sequence through the tonsils. Three neuroradiologists will grade the thickness of the pharyngeal constrictor muscle (the muscle that surrounds the tonsils) on a five-point scale. The study will determine if the pre-operative MRI grading will correlate with positive, insecure (\<1mm), or secure (\>1mm) margin during TORS surgery for your HPV+ tonsillar SCC.
Cirrhosis is a form of advanced liver disease that can lead to serious complications, especially when combined with severe obesity. Many patients with cirrhosis also develop a condition called clinically significant portal hypertension (CSPH), which is increased pressure in the veins of the liver. CSPH raises the risk of life-threatening events like internal bleeding and liver failure. Unfortunately, treatment options for people who have both cirrhosis and severe obesity are very limited, especially when portal hypertension is present. This study, called the OPTIMAL Trial, is a randomized clinical trial designed to evaluate whether combining two procedures improves health outcomes in this high-risk population. The first procedure, called TIPS (Transjugular Intrahepatic Portosystemic Shunt), is a minimally invasive treatment that reduces pressure in the liver by creating a pathway for blood to flow more easily. The second procedure is sleeve gastrectomy, a form of metabolic (bariatric) surgery that helps patients lose weight and improve related conditions like diabetes. The study will compare two groups: 1. One group will receive TIPS followed by sleeve gastrectomy (TIPS+SG). 2. The other group will receive medical weight management (standard non-surgical care, including diet, lifestyle changes, and weight loss medications). All participants will have severe obesity and cirrhosis with CSPH but will not have decompensated liver disease (such as large amounts of fluid in the abdomen, a history of variceal bleeding, or recent liver failure). Eligible participants will be randomly assigned to one of the two groups. The main goal of the study is to determine whether the combination of TIPS + SG improves quality of life and leads to greater weight loss compared to medical therapy alone. The study will also monitor for any complications from either the procedures or the medical treatment. Participants will be followed for 6 months after their treatment starts, with periodic assessments of their physical health, liver function, and overall well-being. Some participants may also be followed for a longer period to assess long-term outcomes. This study hopes to provide high-quality evidence for a novel, stepwise treatment strategy that may help people with obesity and liver disease live longer, healthier lives. If successful, it could change how advanced liver disease and obesity are managed together, especially in patients who currently have few safe and effective options. All study care is provided at Cleveland Clinic, Cleveland, Ohio, USA.
This purpose of this study is to compare the safety and effectiveness of two eye surgery systems-UNITY VCS and CONSTELLATION-in treating adults with vitreoretinal diseases or disorders.
The researchers are doing this study to see if the combination of surgery, locoregional radiation therapy, SBRT (stereotactic body radiation therapy), and the usual approach is more effective in treating oligometastatic HER2-positive breast cancer than the usual approach alone. The researchers will also study the side effects of the study treatment.
standard paradigm for management of patients who present with concern for recurrence of brain metastases following initial stereotactic radiosurgery (SRS).
Postoperative pain remains undertreated with inadequate analgesic options. Opioids have well-known limitations for both individuals and society; single-injection and continuous peripheral nerve blocks provide intense analgesia but are limited in duration to 24-72 hours; and current neuromodulation options-with a duration measured in weeks and not hours-are prohibitively expensive and require an additional procedure. One possible solution is a device currently under investigation to treat postoperative pain. The RELAY system (Gate Science, Moultonborough, New Hampshire) is comprised of a basic catheter-over-needle device to allow administration of a single-injection of local anesthetic via the needle (or catheter) followed by a perineural local anesthetic infusion via the remaining catheter (when desired). Subsequent to the local anesthetic administration, instead of removing the catheter as with all previous continuous peripheral nerve block equipment, electric current may be delivered via the same catheter and an integrated pulse generator for up to 28 days. This is potentially revolutionary because it would allow an anesthesiologist to deliver (1) a single-injection peripheral nerve block; (2) a continuous peripheral nerve block; and (3) neuromodulation using a single device that can theoretically be placed in the same amount of time required for a single-injection peripheral nerve block. Instead of providing fewer than 24 hours of postoperative analgesia, up to 28 days of pain control could be delivered without disruption of existing practice patterns. The ultimate objective of the proposed investigation is to investigate the post-operative analgesic potential of this investigational device and prepare for a pivotal multicenter clinical trial. This feasibility study will be a series of participants all receiving both local anesthetic and electric current via a single device (RELAY, Gate Science, Moultonborough, New Hampshire). The purpose will be to optimize the insertion approach and stimulation administration during the first 7 days following foot and shoulder surgery as well as training the clinical investigators.
To measure the efficacy of postbiotic supplements in mitigating the gut dysbiosis induced by colon cancer surgery. Efficacy in mitigating dysbiosis will be measured by the change in fecal Shannon Diversity Index (SDI) within patients from the baseline sample to various postoperative timepoints. Mean change in SDI from baseline will be compared between groups at 2 weeks postoperative
The goal of this clinical research study is to look at the effectiveness of giving a combination of chemotherapy, immunotherapy, radiation therapy, and surgery to treat soft tissue sarcomas that can be removed by surgery. Researchers want to find out if this treatment combination can extend the time it takes for the disease to relapse (come back after treatment). The safety of this treatment combination will also be studied.

The primary objective of this study is to determine if the addition of Rocklatan post-Hydrus will provide additional intraocular pressure lowering.
The purpose of the study is to compare the efficiency and safety of UNITY™ Vitreoretinal Cataract System (UNITY VCS) to CENTURION® Vision System with Active Sentry (CAS) in adult subjects with grade 2 or greater nuclear sclerotic cataracts who require phacoemulsification in both eyes. Subjects will attend a total of 8 scheduled visits for an individual duration of participation of approximately 1 month.
The goal of this study is to evaluate if a shorter course of therapy can improve the quality of life in patients receiving radiation therapy after trans-oral robotic surgery.
This study involves the retrospecitve review of time stamps during surgery to assess the time efficiencies of different workflow scenarios of femtosecond laser-assisted cataract surgery from the surgeon, staff, and patient perspectives. Objectives are to identify surgical workflows that may increase surgical efficiency and improve patient, surgeon, and staff satisfaction.
This phase II trial compares the effect of adding a probiotic called CBM588 to pembrolizumab versus pembrolizumab alone in preventing return of disease (recurrence) after surgery for patients with renal cell cancer. Pembrolizumab is an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies such as pembrolizumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pembrolizumab is approved for the treatment of renal cell cancer after surgery. Research has shown that changes to the composition of the healthy bacteria in the body (the microbiome), may improve a patient's response to treatment with immunotherapy. CBM588, a probiotic supplement containing a bacteria called Clostridium butyricum, has been shown to improve outcomes in patients treated with immunotherapy for other types of cancer. Adding CBM588 to treatment with pembrolizumab after surgery may cause changes in the microbiome that improve patient response to treatment and reduce disease recurrence, compared to pembrolizumab alone.
Coagulopathic-induced bleeding after cardiopulmonary bypass in cardiac surgery patients is common and is associated with adverse outcomes in cardiac surgery. The hypothesis of the study is that FEIBA will be a more effective treatment than standard of care (FFP) in cardiac surgery patients who have coagulopathic-induced bleeding. This study is being conducted to determine the efficacy of FEIBA versus FFP as first line therapy in correcting coagulopathic induced microvascular bleeding in cardiac surgery patients.
This clinical trial studies whether a disposable negative pressure wound therapy (dNPWT) device, SNaP Wound Care System (Ultraportable Mechanically Powered Negative Pressure Wound Therapy) (SNaP), promotes wound healing in the lower limbs in patients that have undergone Mohs micrographic surgery (Mohs surgery) for non-melanoma skin cancer. Mohs surgery is a surgical technique used to treat skin cancer. Individual layers of cancerous tissue are removed and examined under a microscope one at a time until all cancerous tissue has been removed. It is an important part of removing skin cancer, but it often leads to soft-tissue defects and reconstructive challenges, especially in high-tension areas like the lower limbs. Typically, these wounds are managed by leaving them open and allowing them to heal from the base up or are reconstructed by transferring healthy skin from another part of the body. Negative pressure wound therapy (NPWT) is a wound dressing system that continuously or intermittently applies subatmospheric pressure to the surface of a wound to draw out fluid and promote healing. The SNaP device is a dNPWT device for lower leg wound healing designed for increased portability and ease of use outside of a hospital setting. It is a modification of traditional NPWT devices that uses springs to generate pressure, making it lighter and more user-friendly than traditional devices that rely on electrically powered pumps. This may be a more effective way to promote wound healing in the lower limbs following Mohs surgery for non-melanoma skin cancer.
