An international randomized trial to test the primary hypothesis that perioperative tight blood pressure management reduces a composite of major perfusion-related complications (myocardial injury, stroke, non-fatal cardiac arrest, Stage 2-3 acute kidney injury, deep or organ-space infection, sepsis, and death) in the 30 days after major non-cardiac surgery. The treatments will be: 1) norepinephrine or phenylephrine infusion to maintain intraoperative MAP ≥85 mmHg (tight pressure management); or, 2) routine intraoperative blood pressure management (routine pressure management).

The 2021 ACR RA treatment guideline, based on widely acknowledged low to moderate quality evidence, recommends switching to a non-tumor necrosis factor (TNFi) biologic (choose among existing medications, currently, rituximab, abatacept, tocilizumab, or sarilumab) or a targeted synthetic DMARD arm (tsDMARD; choose among existing medications, currently, tofacitinib, baricitinib, upadacitinib) in patients with active RA despite the use of a TNFi-biologic. In practice, most patients receive another TNFi-biologic, i.e., a second TNFi-biologic first. This is not based on solid evidence, but on arbitrary algorithms often proposed by health insurance plans, and/or physician experience and habit (TNFis launched 22 yrs ago vs. the first tsDMARD 8 years ago vs. first non-TNF-biologic launched 17 years ago). This study will fill a critical knowledge gap by generating CER data for important PROs between these treatment options, switching to a non-TNFi biologic or a tsDMARD in patients with active RA despite the use of a TNFi-biologic.

Obesity is a growing epidemic and bariatric surgery has been shown to be the most effective and efficient mean of achieving significant and sustainable weight loss in morbidly obese individuals. Studies have demonstrated that after LSG, between 5 and 30% of patients suffered from GERD, with a small subset of those patients (2.9 %) converting to another bariatric procedure (gastric bypass) because of debilitating GERD symptoms. The investigators propose this current study to examine mucosal impedance before and after sleeve gastrectomy using the novel mucosal impedance procedure, as well as assess quality of life and GERD symptoms parameters. In addition, this study will determine if the level of mucosal impedance pre-sleeve gastrectomy may predict the development of GERD post-surgery. Our Hypothesis is that sleeve gastrectomy is highly associated with the risk of developing new onset GERD. This is a prospective, comparative cohort study. A total of 15 obese patients (BMI ≥ 35) undergoing sleeve gastrectomy by choice will be recruited into the study from our bariatric and weight management program. An initial screening upper endoscopy will be performed as part of pre-bariatric evaluation, during which mucosal impedance will be performed with the consent of the patient. Patients with evidence of erosive esophagitis (LA grade A-D), Barrett's esophagus or eosinophilic esophagitis will be excluded from the study. As per surgical recommendation, PPI will be used for 6 months in all bariatric patients. Six months post-surgery, study patients will be re-evaluated by the GERD symptoms Checklist and SF 36. In addition, their new BMI will be documented. PPI will be held for at least 1 week and a 6 months post-surgical upper endoscopy will be performed to determine the presence or absence of erosive esophagitis and Barrett's esophagus. In addition, esophageal mucosal impedance will be reassessed.

This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. It may stop the growth of cancer cells that need testosterone to grow. Radiation therapy uses high-energy x rays or protons to kill tumor cells. The addition of relugolix to the radiation may reduce the chance of oligometastatic prostate cancer spreading further.

Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread.

This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells.

Anti-inflammatory drugs, such as dexamethasone lower the body's immune response and are used with other drugs in the treatment of some types of cancer.
