Veliparib, Paclitaxel, and Carboplatin in Treating Patients With Solid Tumors That Are Metastatic or Cannot Be Removed by Surgery and Liver or Kidney Dysfunction

This phase I trial studies the side effects and the best dose of veliparib when given together with paclitaxel and carboplatin in treating patients with solid tumors that are metastatic or cannot be removed by surgery and liver or kidney dysfunction. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, 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. Giving veliparib together with paclitaxel and carboplatin may kill more tumor cells.

Pilot Study Dara-CyBorD in Newly Diagnosed Multiple Myeloma Patients With Renal Failure

The goal of this study is to assess the efficacy of induction treatment with daratumumab-hyaluronidase (dara SC) with cyclophosphamide, bortezomib, and dexamethasone (Dara-CyBorD) for four cycles in patients with newly diagnosed multiple myeloma who have new onset renal failure. This study will also investigate the difference responses in African American (AA) patients versus non-African American patients. The primary questions this study aims to answer are: 1. To evaluate the very good partial response rate (VGPR) after 4 cycles of Dara-CyBord. 2. To evaluate the renal response rate (RRR) after 4 cycles of Dara-CyBord.

SAVE-FistulaS: the SelfWrap-Assisted ArterioVEnous Fistulas Study

Advancing Health Information Exchange (HIE) During Inter-hospital Transfer (IHT) to Improve Patient Outcomes

Sub-optimal transfer of clinical information during inter-hospital transfer (IHT, the transfer of patients between acute care hospitals) is common and can lead to patient harm. To address this problem, the investigators will use key stakeholder input to refine and implement an interoperable health information exchange platform that integrates with the electronic health record and improves the reliability of and access to necessary clinical information in three use cases involving transfer of patients between sending and receiving hospitals with varying levels of affiliation and health record integration. The investigators will assess the effect of this intervention on frequency of medical errors, evaluate the use and usability of this platform from the perspective of those that interact with it, and use these results to develop a dissemination plan to spread implementation and use of this platform across other similar institutions.

Post-Filter Hematocrit

Filter clotting is a major complication of continuous renal replacement therapy (CRRT), resulting in blood loss, reduced treatment efficacy, and increased cost. One modifiable factor associated with filter clotting is filtration fraction (FF), or the proportion of plasma water being removed from the blood over the course of the filter. In convention, a cutoff of FF\<20-30% has been used to prevent hemofilter clotting, but no evidence correlating FF with hemofilter clotting has been documented. Some experts have proposed that post-filter hematocrit (Hct) could be a more direct marker for determining hemofilter clotting risk, but evidence supporting clinical utility of this marker is lacking. HCTpost=HCTpre/(FF(HCTpre-1)+1) In our proposed validation study, we hope to determine whether our formula for post-filter Hct provides accurate results when compared to measured values. The information obtained from this study will potentially justify the use of utilizing the formula in future studies. The procedure of this study is collecting blood samples from the post-filter lines of patients on CRRT at different time points and different flow rates. This will be considered the "measured post-filter hematocrit" which will then be compared to the calculated formula above, using the other values obtained from daily labs (for pre-filter hematocrit) and CRRT machine settings.

SGLT2 Inhibition in Addition to Lifestyle Intervention and Risk for Complications in Subtypes of Patients With Prediabetes

More than 50% of patients with type 2 diabetes develop micro- and/or macrovascular complications during the course of the disease. Additionally, many patients at risk for diabetes develop metabolically driven complications including kidney and heart disease. Thus, it is of utmost importance to improve prevention of T2D and with this complications. Remission of prediabetes, i.e. normalization of hyperglycemia by means of lifestyle intervention is one of the most effective ways to prevent the development of T2D and complications. Novel sub-phenotyping analysis identified clusters of risk for diabetes associated with different complications, opening opportunities to new therapeutic approaches, despite and in addition to lifestyle changes. So far, pharmacological therapy is not indicated for patients with prediabetes. Remission of hyperglycemia associated with prediabetes during lifestyle interventions not only prevents T2D but is also linked with reduced albuminuria and lower microvascular and kidney complications. Thus, reaching normoglycemia (i.e. prediabetes remission) is important for reducing the risk of (pre-)diabetes-associated complications including micro- and even macrovascular disease. In patients with T2D, recent data show that dapagliflozin can improve diabetes remission, and thus, likely complications. However, to date no data have assessed whether or not this is also true in patients with hyperglycemia related to prediabetes which, as outlined above, already causes different complications. Subphenotyping of patients with newly onset diabetes suggests that for some individuals, it would be too late to start interventions against dagainst complications at the time of diagnosis of type 2 diabetes. Therefore, individuals at elevated risk to develop T2D and complications should receive preventive measures well before the diagnosis of T2D. This study will provide evidence whether such an early intervention contributes to the remission of hyperglycemia related to prediabetes to protect from associated complications such as renal disease. The studied population will comprise individuals who have hyperglycemia in the range of prediabetes and are thus prone to not only develop T2D, but also early nephropathy but in clinical practice do not receive medical treatment due to the early stage of the disease. These subjects will receive Dapagliflozin 10 mg or Placebo for 6 months. The placebo treatment arm reflects current practice. In order guarantee a benefit the patients in the placebo arm will receive a lifestyle intervention.

Participants were selected based on three groups: healthy, chronic obstructive pulmonary disease, and chronic renal disease. NIRS was used to measure tissue oxygenation on the thenar region of the right hand. A pressure cuff was used to temporarily occlude arterial inflow, thus allowing the response to this to be assessed. The StO2 was plotted against time, and the following variables were calculated, the downslope, upslope, area under curve.

Can Dapagliflozin Preserve Structure and Function in Transplanted Kidneys?

The goal of this clinical trial is to look at the effect of SGLT2 (Sodium glucose transporter 2) inhibition in patients receiving a kidney-transplant 6 weeks earlier at Oslo University hospital. Rikshospitalet. Investigators will search for answers along three pathways: Can SGLT2 inhibitor 1) preserve glomerular filtration rate (GFR), 2) reduce interstitial fibrosis in the kidney, and 3) favorably improve metabolic risk factors for graft failure such as visceral obesity, glucose intolerance and high blood pressure? The participants (N=330) will be randomized to either dapagliflozin 10 mg or placebo o.d. in a blinded fashion. Researchers will than use kidney transplant biopsies, measured GFR, blood pressure sampling, glucose tolerance test (OGTT), dual-energy X-ray absorptiometry (DXA scan) and estimated GFR from the two groups in comparison, to evaluate the effect treatment. The participants will be followed for a total of 3 years.

Music Intervention for Dialysis Patients

The goal of this clinical trial is to examine the efficacy of both live and pre-recorded music interventions on alleviating the negative effects of dialysis treatment. The main questions it aims to answer are: * Does music intervention have an effect on experienced pain, itch, anxiety, depression, and quality of life in dialysis patients? * To what extent do pre-recorded and live music performances differ in their effect on experienced pain, itch, anxiety, depression, and quality of life in dialysis patients? Participants will Attend their regularly scheduled dialysis appointments for one week, and baseline data will be gathered (pain/itch NRS, WHO-5, DASS21). During the second week, participants will be exposed to live music, and research data will be gathered. This process will then be repeated in weeks 3 and 4, but with pre-recorded music as the intervention method. Researchers will compare baseline data to intervention data (within group comparison), as well as live music to pre-recorded (between group comparison).
