This investigator-initiated, open-label, randomized controlled trial will explore the effects of two treatment arms, comparing standard treatment with normal saline against Irrisept, a jet lavage solution containing a low concentration of Chlorhexidine Gluconate (CHG) at 0.05% in 99.95% sterile water for irrigation. The study aims to evaluate the impact on postoperative wound healing in patients who have undergone cesarean delivery.

Prior research suggests that it is possible to improve health outcomes in children with ACEs through multi-component interventions. The challenge for most communities is that health and education systems are fragmented and fail to accommodate families based upon different levels of need. This study utilizes cross-sectoral partnerships to mobilize three vectors (pediatricians, community health workers and parenting educators) to optimize the delivery of vital information and resources to a diverse population of families with ACEs. All vectors are trained in an evidence-informed curriculum to strengthen families and build youth resilience. The study design is a randomized controlled trial of 340 families of children between the ages of 3 to 11 who are generally healthy and have recently seen a pediatrician for a well-child visit. To evaluate the efficacy of this intervention, pediatric patients are invited to participate in repeat evaluations within 2 weeks, 3 months, 6 months, and 12 months after their well-child visit. The study will evaluate the following: 1) the association between Child-ACE scores and biomarkers of toxic stress at baseline in children age 3-11 years old; 2) whether the intervention reduces toxic stress and child health and psychosocial problems at follow-up for children with ACEs compared to usual well-child care for children with ACEs; and 3) the impact of mediating and moderating variables. These results will demonstrate that for families with ACEs the intervention will decrease toxic stress associated with ACEs, improve health outcomes, and reduce health disparities.

This study is being conducted to help the investigators better understand how the new FDA approved medication Edaravone (also known as Radicava) works in subsets of patients with ALS. The investigators are also trying to understand if there are specific ALS patients, with different presentations of ALS, who might benefit most from this medication. Also, the investigators are following specific biomarkers to determine the optimal treatment duration in patients with different forms of ALS There is no study medication being offered in this trial. Edaravone is prescribed as part of regular care. In this trial we are collecting blood, urine, and spinal fluid samples in ALS patients who are taking Edaravone and ALS patients who are not taking Edaravone to measure certain markers that could indicate why the drug may be working in a specific type of ALS.

Local control of hepatic metastases appears to be a major determinant of overall survival. However, many patients are not suitable for resection due to medical or surgical reasons. Therefore, there is an important role for a treatment that can provide the equivalent of tumor resection with minimal morbidity. Stereotactic body radiotherapy (SBRT) delivers an ablative regimen of highly focused external beam radiotherapy that targets one or more discrete extracranial lesions. Published reports using SBRT to treat liver metastases have shown actuarial local control rates ranging from 50-100% with higher doses associated with better local control. In patients with metastatic liver disease, aggressive local therapy using modern radiotherapy techniques are promising and project to have a substantial role in the treatment of metastatic liver cancer to treat unresectable disease. The dosimetric advantage of proton therapy may lead to improved clinical outcomes with less morbidity, however, there is no clinical data to confirm this assertion. We thus propose a phase I study to determine the feasibility and safety of stereotactic body proton therapy in patients with liver metastases followed by a phase II study to determine the efficacy of such treatment on local control.

The goal of this phase II study is to investigate the feasibility, toxicity and efficacy of a regimen incorporating a proven systemic regimen, carboplatin /paclitaxel, with conformal proton modality, followed by definitive surgery. In most combined-modality trials to date, chemotherapy regimens have included cisplatin, usually in conjunction with 5-fluorouracil. In designing the regimen, the investigators attempt to improve on the standard cisplatin/5-fluorouracil regimen in several ways. First, full-dose paclitaxel is added to the regimen. This agent has activity against advanced esophageal cancer and is also a potent radiosensitizer. Second, the substitution of carboplatin for cisplatin has resulted in reduced toxicity of various combination regimens similar to that used by CROSS trial and allows for easier administration in the outpatient setting.4 Third, for localized esophageal cancer, dose distribution patterns achievable with proton beam could potentially offer important clinical advantages relative to those achievable with x-rays (photons).19 Based on this, the investigators believe that this study should be conducted with the radiation modality that offers the best dosimetry achievable at our institution.

The purpose of this graduate student research study is to compare the effects of low-load blood flow restriction training (LL-BFR) and heavy-load training (HLT) in high-volume rowers with mild low back pain or recurrent low back pain (LBP), aiming to determine whether LL-BFR offers a safer yet equally effective alternative to HLT for enhancing performance and reducing risk of re-injury.

The goal of this clinical trial is to learn if a community health worker led intervention that helps facilitate palliative care works to treat newly-diagnostic pancreatic cancer. It will also help understand the impact of this intervention on people who are caregivers for patients with pancreatic cancer. The main questions it aims to answer are: Does the community health worker improve symptoms and quality of life in patients with pancreatic cancer? Does the community health worker improve the burden of caregiving and quality of life in family caregivers? Researchers will compare drug ABC to a control (where patients get the care that patients with pancreatic cancer receive including access to handouts and videos that the investigators provide patients by national organizations) to see if the intervention works to help patients with pancreatic cancer. Participants will: Meet with study staff several times over 3 months and complete surveys about their experience and symptoms Patients assigned with the community health worker will meet with them in person or video.

This is an ancillary study of NCT06159543, which was a clinical trial that examined the effect of a 12-week 1.5 cups daily mango crossover intervention on cardiometabolic outcomes in individuals with prediabetes, male and female, and 40-60 years of age. The goal of this ancillary study is to test the effect of the mango intervention on gut health markers in individuals with prediabetes. The main questions it aims to answer are: 1. What is the effect of 1.5 cups per day of fresh mango over 12 weeks on indicators of gut permeability as measured by lipopolysaccharide-binding protein (LBP) and soluble CD14 (sCD14)? 2. What is the effect of 1.5 cups per day of fresh mango over 12 weeks on microbiome modulation as estimated by short chain fatty acids (SCFAs)? Secondarily: 1. Is LBP a mediator of the relationship between systemic inflammation \[as determined by C-reactive protein, E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1)\] and SCFAs? 2. Is LBP a mediator of the relationship between insulin resistance \[as determined by HOMA-IR\] and SCFAs? 3. Is sCD14 a mediator of the relationship between systemic inflammation \[as determined by C-reactive protein, E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1)\] and SCFAs? 4. Is sCD14 a mediator of the relationship between insulin resistance \[as determined by HOMA-IR\] and SCFAs? Researchers will compare the 12 weeks participants consume mango to the 12 weeks the participants are not consuming mango to see if there are differences in LBP, sCD14, and SCFAs. As noted, this is an ancillary study of NCT06159543. Fasting blood was collected at baseline, and at the end of each phase of NCT06159543. This blood will be used to analyze LBP, sCD14 and SCFAs. Fasting blood and insulin were analyzed in NCT06159543, and will used to calculate HOMA-IR in the ancillary study. C-reactive protein, E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) will be analyzed NCT06159543.

The goal of this clinical trial is to determine whether Emotional Brain Training (EBT), a behavioral modification method, can help manage stress and health problems related to addiction. EBT teaches skills to deactivate harmful circuits (automatic reactions) and activate healing circuits to quickly shift mood from negative to positive. Participants in the EBT group will receive focused, intensive instruction on using these skills to rewire unwanted brain circuits, with the aim of achieving lasting improvements in emotional health and quality of life. The study will assess whether EBT is an effective tool when added to standard of care (SOC), which includes medications for addiction treatment (MAT). Researchers will compare changes in stress, anxiety, and cravings after 8 weeks of EBT plus SOC versus SOC alone. Participants: * will either continue receiving standard treatments (SOC) at the Addiction Recovery Clinic (ARC) at SAC Health in San Bernardino * or receive both EBT and SOC at ARC * in the SOC group will continue monthly visits at ARC and weekly counseling * in the EBT plus SOC group will continue monthly visits and weekly counseling at ARC, along with weekly EBT group sessions by telephone * will complete online assessments at weeks 0, 4, and 8 Upon completion of the study, all participants will resume SOC

The purpose of this investigator-initiated study is to provide an efficient and non-invasive treatment option for pain caused by the piriformis muscle.

Magnesium Sulfate(MgSo4) is increasingly being used as part of the multimodal pain regimen in the perioperative period. The intraoperative neurophysiological monitoring (IONM) is utilized in complex spine and cranial surgeries to assess the functional integrity of the neural pathways. The effect of Magnesium sulfate on IONM has not been studied. This is a prospective, double blind, randomized placebo controlled trial to study the effect of Magnesium sulfate bolus on the amplitude and latency of somatosensory(SSEPs) and motor evoked potentials(MEPs) in patients undergoing surgery requiring IONM.

The opioid epidemic continues to be a major public health crisis in the United States. According to the Center for Disease Control, approximately 8 million Americans reported misusing prescription opioids in 2023, with over 5 million Americans reporting that they suffer from opioid use disorder. The United States government estimates that 105,000 people died from drug overdose in 2023, and approximately 80,000 of those deaths can be attributed to opioids (\~76%). In acknowledgement of the opioid crisis, we wish to contribute to ongoing efforts to reduce unnecessary and excessive opioid prescription. In 2012, researchers in Iran published a randomized controlled trial comparing intravenous (IV) lidocaine to IV morphine for acute renal colic, reporting that 90% patients responded "successfully" in the lidocaine group versus 70% in the morphine group. They also concluded that there was a statistically significant difference between pain scores between the two groups at all time points, favoring the lidocaine group. However, the study was conducted at a single emergency department in Tabriz, Iran, with a relatively homogenous patient population, and the researchers did not explicitly define their primary outcome variable for what constituted a "successful" response in the treatment groups. The investigators of this study aim to build upon this preliminary evidence by recruiting a more diverse population to improve generalizability and by predefining pain-reduction thresholds to allow for more meaningful comparison between the interventions.

Exploring the effect of team-based ARTAS intervention in an inpatient setting on HIV linkage to care and hospital readmission rates.

The goal of this treatment study is to determine if doing lateral pharyngoplasty with tonsillectomy is better for children than doing tonsillectomy alone. The main questions it aims to answer are: * Do children experience less pain after surgery when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? * Do children eat/drink better when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? * Is there a lower risk of bleeding after tonsillectomy when lateral pharyngoplasty is performed? Researchers will compare children undergoing tonsillectomy and lateral pharyngoplasty with children undergoing tonsillectomy alone to see if the participants experience less pain, better oral intake, and less bleeding complications after surgery. Parents of participants will be asked to record pain scores and pain medications given, approximate amounts of daily oral intake, and any complications after surgery.

The study will examine the temporary volumetric change that happens in the gums around an implant crown when the crown is removed. The main question of the study is "how much time has to pass to see a significant change, especially when there could be a need to make a mold of the surrounding gum to make a new crown?" The area of the implant crown will be scanned with an intra-oral scanner over a period of 15 minutes.

The goal of this double blinded randomized control trial is to learn if percutaneous cryoablation of traumatic rib fractures improves outcomes. The main questions it aims to answer are: Does percutaneous cryoablation improve short and long term pain scores? Does percutaneous cryoablation improve short and long term respiratory mechanics? Does percutaneous cryoablation improve long term quality of life? Does percutaneous cryoablation decrease delirium? Researchers will compare cryoablation to standard multimodal pain therapy to see if this impacts respiratory recovery. Participants will undergo randomization, percutaneous cryoablative procedure, and participate in tests at pre-determined intervals to evaluate their pulmonary recovery.
