Surgery Clinical Trials

The purpose of this study is to investigate the efficacy of a positive affect enhancing intervention designed to reduce pain and augment reward system function in knee osteoarthritis (KOA) patients undergoing total knee arthroplasty (TKA). The scientific premise is that patient use of a positive emotion generative practice - savoring meditation, which has been demonstrated to reduce pain in experimental laboratory settings, enhanced with a pain neuroscience education component about reward system dysfunction as a chronic pain mechanism - is optimally suited to reduce postsurgical pain and augment reward system functioning relative to a Pain Self-Management and Education (PSME) condition. We will randomize 150 patients with KOA undergoing unilateral TKA to a brief, 4-session (20-30 minutes each) course of Savoring Meditation (SM; n = 75) or PSME (n = 75) delivered remotely by trained interventionists in a one-on-one format. We will assess pain and as well as pain-related risk and protective factors both via questionnaire and via weeklong ecological momentary assessment (EMA) data bursts on the following schedule: baseline, post-surgery, and 3-month follow-up. In addition, participants will attend laboratory testing sessions at baseline and 6-weeks post-surgery, during which affective pain modulation and electroencephalographic (EEG) brain biomarkers associated with pain and affect will be recorded. Participants in SM be encouraged to practice their savoring for 5 minutes/day during the week following surgery, as well as to use it to manage pain flares in a self-directed manner. Read Less

The Study is designed to collect information about adverse events that occur in children undergoing anesthesia in participating hospitals. Demographic information will be collected on all anesthetics. An analysis of each adverse event will be performed and entered into the database. From this information we will devise strategies to prevent these adverse events. Read Less

There are key differences today in clinical practice regarding perioperative management of post-PCI patients on DAPT undergoing NCS. Moreover, there are significant differences between bridging agents, and improved safety of current-generation DES. Given the significant limitations of current studies a well-designed registry to study current U.S. practice patterns and the bleeding or ischemic risks associated with the various perioperative DAPT management strategies including bridging and no bridging will significantly add to the understanding of the current problem and associated risks of patients. These data could form the basis for conducting future randomized clinical trials (RCTs) in this area. NCS in post-PCI patients on chronic DAPT presents a complex interaction of both ischemic and bleeding risks. The MARS registry will study the area of perioperative antiplatelet therapy management through a multicenter observational national registry designed to collect pre-operative, intra-operative and post-operative clinical strategies, therapeutic interventions and outcomes data. This proposal outlines the role of a highly experienced clinical trial team to conduct a multicenter prospective registry. This question is highly relevant to a diverse group of medical providers and millions of patients in the US and around the world; this will be the first such U.S. registry to address this critically important public health issue. Study objectives: i. To collect data on contemporary clinical practice in the U.S. on managing post percutaneous coronary intervention (PCI) DAPT in patients scheduled to undergo NCS and CS. ii. To assess ischemic and bleeding endpoints in this group of patients during the study period. iii. To generate initial data to plan for future large-scale randomized clinical trials on perioperative management of DAPT. Read Less

The current postoperative cataract surgery eye drop regimen used at Zuckerberg San Francisco General Hospital (ZSFG) is a significant burden for its patient population, contributing to high rates of non-adherence and the development of postoperative complications. The investigators propose to replace this complex regimen with a single administration of intraocular antibiotic and subconjunctival steroid at the time of surgery. This pilot study will obtain the preliminary data required to eventually fully evaluate this innovation in postoperative care in a safety-net population with respect to postoperative outcomes, patient compliance, and patient and caregiver satisfaction.

Describe the purpose and objective(s) of the study, specific aims, and/or research questions/hypotheses: The purpose of this Randomized Controlled Trial is to evaluate the effectiveness of Blood Flow Restriction (BFR) training with standard care of physical therapy versus the standard care of Physical Therapy alone and its effect on shoulder function and patient outcomes in military cadets recovering from shoulder stabilization surgery. We hypothesize after 6 weeks of BFR training will contribute to 13 (76%) or more participants will achieve scores within one standard deviation of normative values for isometric strength and functional tests at six months following shoulder stabilization surgery. Furthermore, we hypothesize that 14 (82%) or more participants will report improved patientreported outcomes as determined by the minimal clinical difference (MCD) at 12 weeks and six months post-operatively. Objective 1: To evaluate the effectiveness of blood flow restriction (BFR) training on shoulder isometric strength, as measured by a digital handheld dynamotor following shoulder stabilization surgery in military cadets. Objective 2: To evaluate the effectiveness of blood flow restriction (BFR) training on shoulder range of motion, as measured by a digital inclinometer, following shoulder stabilization surgery in military cadets. Objective 3: To evaluate the effectiveness of blood flow restriction (BFR) training on shoulder function as measured by the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST), Seated Shot-Put Test (SSPT), and Upper Quarter Y-Balance Test (UQYBT), following shoulder stabilization surgery in military cadets. Objective 4: To evaluate the effectiveness of BFR training on shoulder pain, measured by a numerical pain rating scale, following shoulder stabilization surgery in military cadets. Objective 5: To evaluate the effectiveness of a BFR training on patient-reported outcomes, measured by Single Assessment Numeric Evaluation (SANE), Shoulder Pain and Disability Index (SPADI), and the Quick Disabilities of Arm, Shoulder and Hand (DASH) following shoulder stabilization surgery in military cadets. Aim 1:To identify whether BFR with Physical Therapy is more effective at increasing shoulder strength than therapy alone following shoulder stabilization surgery. We hypothesize that the BFR with Physical Therapy group will be more effective at increasing shoulder strength than the Physical Therapy group without BFR following shoulder stabilization surgery. Aim 2:To identify whether BFR with Physical Therapy is more effective at increasing shoulder function than therapy alone following shoulder stabilization surgery. We hypothesize that the BFR with Physical Therapy group will be more effective at increasing shoulder function than the Physical Therapy group without BFR following shoulder stabilization surgery.

Our goal is to compare the difference in surgical outcomes and patient satisfaction for surgical scars on the face between suture removal at 1 week versus 2 weeks. There is variation in the timing at which Mohs surgeons remove sutures on the face. Some prefer 1 week, and others prefer 2 weeks. This has not been formally studied. It is possible the outcomes are the same between both groups, or that one has a better cosmetic outcome than the other. Your skin cancer will be removed as usual. After this, your wound will be sutured in the usual fashion, except the top sutures will be divided into two separate halves. You will return at 1 week for one half of the top sutures to be removed, and at 2 weeks for the other half to be removed. Which half is removed first will be determined at random at your 1 week visit. At two months, you will return for standardized photographs which will be used by physicians to rate the cosmetic outcomes of the wound halves based on a standardized scale. Most likely, there will be no difference between the wound halves at 2 months and the study is complete. There is a small chance that there will be a cosmetic difference seen at 2 months, in which case you will return at 1 year for repeat standardized photographs and ratings. All data and photographs will be kept secure and any identifying information will be destroyed at the end of the study. Read Less

The concept of "enhanced recovery" was introduced by European anesthesiologists and surgeons who challenged traditional clinical practices involved in peri-operative care in 1990s. The goal of enhanced recovery programs (ERP) is to maintain normal physiology thereby decreasing complications. It focuses on peri-operative optimization of patient care. It was originally created for open colorectal surgeries but now has shown benefit in various surgical specialities including thoracic surgery, vascular surgery, hepatobiliary as well as gynecological surgery. The successful implementation of structured ERAS program requires an ERAS protocol, audit system and a multidisciplinary team. The investigators will evaluate the effect of compliance with the protocol and outcomes such as length of stay, readmissions, morbidity and mortality. Read Less

The overarching goal of this project is to assess whether a controlled short-term Time restricted feeding (TRF) intervention leads to metabolic benefits, improves recovery after vascular surgery and that TRF is safe. Participants suffering from intermittent claudication (Fontaine stage II peripheral artery disease, PAD) will be randomly assigned to a 2-week TRF or active control dietary advices before open surgical revascularization. Prior to the surgery, the investigators will assess the eating patterns of participants with an innovative smartphone application ('app') which is less intrusive and more reliable than food diaries/questionnaires to assess eating behavior and patterns. In the second part of the study, the investigators will investigate whether a short term TRF intervention improves surgical recovery, in the short-term (1 month, primary endpoint) and long-term (optional, up to 1 year), as part of the routine clinical follow-up. This proposal builds on established expertise in the biology of dietary intervention, surgery, and study of eating patterns in human. Read Less

This research will test the hypothesis that immune system disequilibrium / dysfunction explains why preoperative cognitive impairment is a strong predictor of postoperative morbidity in older surgical patients. The investigators propose that cognitive impairment influences surgical morbidity because of underlying immune disequilibrium / dysfunction (risk marker) and that this shapes the immune response to surgery and defines immunological hallmarks of postoperative morbidity (disease marker). The overarching goal of this application therefore is to define and better understand the clinical immunology underlying the relationship between cognition and geriatric surgical morbidity. Read Less
