This screening and multi-sub-study randomized phase II/III trial will establish a method for genomic screening of similar large cancer populations followed by assigning and accruing simultaneously to a multi-sub-study hybrid Master Protocol (Lung-MAP). The type of cancer trait (biomarker) will determine to which sub-study, within this protocol, a participant will be assigned to compare new targeted cancer therapy, designed to block the growth and spread of cancer, or combinations to standard of care therapy with the ultimate goal of being able to approve new targeted therapies in this setting. In addition, the protocol includes non-match sub-studies which will include all screened patients not eligible for any of the biomarker-driven sub-studies. Read Less

To test how two weeks of curcumin supplementation would cross the blood brain barrier (BBB) and attach to amyloid beta proteins, to assess the feasibility (safety and bioavailability), and to explore the resulting abundance/composition of gut microbiota. Read Less

This pilot study evaluates the tolerability and feasibility of the Axoguard Large-Diameter Nerve Cap (sizes 5-7 mm) for protecting and preserving terminated nerve endings after limb trauma or amputation when immediate attention to the nerve injuries is not possible. Read Less

Cardiomyopathy is a major complication of doxorubicin (DOX) chemotherapy, and 10-21% of breast cancer patients receiving DOX experience compromised cardiac function. Recent advancements have increased cancer survivorship but it remains clinically challenging to mitigate the cardiotoxic side effects. Although there are several strategies used to reduce the occurrence and severity of DOX-induced cardiotoxicity, they are not particularly effective. Hence, there is an urgent need to develop new strategies that prevent the cardiotoxic effects of DOX but maintain its potency as a cancer therapy. Because the cellular events responsible for the antitumor activity of DOX and DOX-induced cardiotoxicity are distinctly different, it may be possible to develop therapies that selectively mitigate DOX-induced cardiotoxicity. Thus, the investigators propose to test an adjuvant therapy that combines the phytochemical sulforaphane (SFN) with DOX to attenuate DOX-induced cardiomyopathy. SFN activates the transcription factor Nrf2 and induces defense mechanisms in normal cells. Furthermore, SFN inhibits carcinogenesis and metastases and enhances cancer cell sensitivity to DOX, seemingly through Nrf2-independent mechanisms. SFN has also been tested in several clinical trials, although never together with DOX. Our early animal studies suggest that by activating Nrf2, SFN selectively protects the mouse and rat from DOX cardiotoxicity, enhances survival and enhances the effects of DOX on cancer growth in a rat breast cancer model. The investigators suspect that SFN affects DOX metabolism in cancer cells to enhance tumor regression, or it may synergistically activate other key antitumor mechanisms. Hence, SFN may improve the clinical outcome of cancer therapy by (1) attenuating DOX cardiotoxicity and (2) enhancing the effects of cancer treatment on the tumor. Our hypothesis is that SFN protects the heart from DOX-mediated cardiac injury without altering the antitumor efficacy of DOX. In Aim 1, the investigators will conduct an early-phase clinical trial to determine if SFN is safe to administer to breast cancer patients undergoing DOX chemotherapy. In Aim 2, the investigators will determine if SFN decreases DOX-induced inflammatory responses and enhances Nrf2- and SIRT1-target gene expression in breast cancer patients. Notably, transcript and protein signatures in peripheral blood mononuclear cells (PBMCs) can predict cardiac function in patients undergoing DOX chemotherapy for breast cancer. The investigators will also determine if SFN/DOX treatment activates Nrf2- and SIRT1-dependent gene expression, alters the levels of biomarkers for presymptomatic DOX-cardiotoxicity and mitigates the generation of cardiotoxic metabolites in PBMCs and plasma. These studies will facilitate the development of SFN co-treatment as a strategy to enhance the efficacy and safety of DOX cancer therapy. Read Less

This study is a registry of general use of Avance Nerve Graft and is intended to evaluate the uses, response rates, and safety of Avance Nerve Graft in the real-life clinical setting. Optional addendums 1 and 2 included in the protocol are intended to establish comparative groups and focused subgroups within the registry. Read Less

This randomized phase III trial studies how well crizotinib works in treating patients with stage IB-IIIA non-small cell lung cancer that has been removed by surgery and has a mutation in a protein called anaplastic lymphoma kinase (ALK). Mutations, or changes, in ALK can make it very active and important for tumor cell growth and progression. Crizotinib may stop the growth of tumor cells by blocking the ALK protein from working. Crizotinib may be an effective treatment for patients with non-small cell lung cancer and an ALK fusion mutation. Read Less

While appendectomy has been the main treatment of appendicitis for over 100 years, recent European studies found that, at least among highly selected patients, antibiotics alone can be an effective alternative. Surgeons and patients alike have a difficult time deciding if surgery or antibiotics are the best choice to treat appendicitis. The goal of the TRIAD is to evaluate the patients who are a part of the TRIAD implementation program and assess satisfaction and decisional regret for patients with appendicitis. This information will be used to inform the design of decision-support interventions to help patients improve their ability to make an informed decision in-line with their preferences and values.

Postmenopausal women are at a risk of excessive weight gain, bone loss, hypertension, and metabolic syndrome. Obesity-induced chronic low-grade inflammation is initiated by excess nutrients in metabolic cells. Recent studies have indicated tocotrienols (one kind of vitamin E, a potent antioxidant) supplement may be good for mitigating negative impacts of obesity in postmenopausal women. The purpose of the study is to examine the effect of 24-week tocotrienols on obesity-associated outcome measurements in postmenopausal women. The investigators will enroll 60 qualified women at the start of the study and randomly assigned to no tocotrienols (placebo) or tocotrienols group for 24 weeks. Obesity-associated measurements will be recorded using blood, urine, adipose tissue, and fecal samples. All data will be analyzed statistically. Read Less
