Factors Impacting Early Adverse Outcomes in Simultaneous Heart-Kidney Transplantation.

Background: Over the last decade, the number of simultaneous heart-kidney transplants (SHKTs) has increased dramatically. There are few reports of renal allograft outcomes in these high acuity patients. The goal of the present study was to identify variables that were related to early adverse outcomes (EAOs), including delayed graft function (DGF), primary non-function (PNF), and renal allograft futility (RAF) after SHKTs.

Enhanced triplet superconductivity in next-generation ultraclean UTe.

The unconventional superconductor UTe[Formula: see text] exhibits numerous signatures of spin-triplet superconductivity-a rare state of matter which could enable quantum computation protected against decoherence. UTe[Formula: see text] possesses a complex phase landscape comprising two magnetic field-induced superconducting phases, a metamagnetic transition to a field-polarized state, along with pair- and charge-density wave orders. However, contradictory reports between studies performed on UTe[Formula: see text] specimens of varying quality have severely impeded theoretical efforts to understand the microscopic origins of the exotic superconductivity.

Medical and Surgical Weight Loss as a Pathway to Renal Transplant Listing.

Purpose: Severe obesity is a barrier to listing for kidney transplantation due to concern for poor outcomes. This study aims to compare bariatric surgery with medical weight loss as a means of achieving weight loss and subsequent listing for renal transplant. We hypothesize that bariatric surgery will induce greater frequency of listing for transplant within 18 months of study initiation.

Food availability aligns with contrasting demographics in populations of an at-risk songbird.

Golden-winged Warblers () have become rare across much of their historic breeding range and response to conservation efforts is variable. Evidence from several recent studies suggests that breeding output is a primary driver explaining responses to conservation and it is hypothesized that differences in food availability may be driving breeding output disparity between two subpopulations of the warbler's Appalachian breeding range. Herein, we studied two subpopulations: central Pennsylvania ("central subpopulation"), where breeding productivity is relatively low, and eastern Pennsylvania ("eastern subpopulation"), where breeding productivity is relatively high.

Inaccuracy of Initial Clinical Mobility Assessment in Venous Thromboembolism Risk Stratification.

Background: Venous thromboembolism risk increases in hospitals due to reduced patient mobility. However, initial mobility evaluations for thromboembolism risk are often subjective and lack standardization, potentially leading to inaccurate risk assessments and insufficient prevention.

Methods: A retrospective study at a quaternary academic hospital analyzed patients using the Padua risk tool, which includes a mobility question, and the Johns Hopkins-Highest Level of Mobility (JH-HLM) scores to objectively measure mobility.

A2/A2B to B kidney transplantation outcomes: A single center 7-year experience.

Introduction: Data on long-term outcomes following A2/A2B to B kidney transplants since the 2014 kidney allocation system (KAS) changes are few. The primary aim of this study is to report our 7-year experience with A2/A2B to B kidney transplants and to compare post-transplant outcomes of A2/A2B to a concurrent group of B to B kidney transplants. Additionally, the study evaluates the impact of pre-transplant anti-A1 titers on survival outcomes in A2/A2B transplants.

Kidney Transplantation Anastomotic Time Is Jointly Associated With Resident and Attending Experience.

Introduction: Few studies evaluate the interplay of attending and resident learning curves in surgical education. Anastomotic time is known to be correlated with transplant outcomes in kidney transplantation. We aimed to evaluate the correlation between the combination of resident and attending experience and anastomotic time in kidney transplantation.

Twelve-month kidney and liver outcomes of kidney transplantation from Hepatitis C Viremic deceased donors to aviremic recipients.

Introduction: Utilization of hepatitis C viremic (HCV+) deceased donor kidneys (DDKT) for aviremic recipients increases opportunities for transplantation with excellent short-term outcomes. Our primary aim was to understand longer-term outcomes, specifically assessing kidney and liver function in the first year posttransplant.

Methods: This was a retrospective single-center study of adult DDKT recipients of HCV+ kidneys (cases) matched 1:1 to recipients of HCV- kidneys (comparators).

A Phase 2 Study of Sitravatinib in Combination with Nivolumab in Patients with Advanced or Metastatic Urothelial Carcinoma.

Background And Objective: Checkpoint inhibitor therapy (CPI) has demonstrated survival benefits in urothelial carcinoma (UC); however, not all patients benefit from CPI due to resistance. Combining sitravatinib, a multitargeted receptor tyrosine kinase inhibitor of TYRO3, AXL, and MERTK (TAM) receptors and VEGFR2, with CPI may improve antitumor responses. Our objective was to assess the efficacy and safety of sitravatinib plus nivolumab in patients with advanced/metastatic UC.

The Kidney Transplant: Maintaining Excellent Outcomes While Increasing Skills Acquisition.

Objective/background: Kidney transplantation is a complex operation that incorporates multiple fundamental surgical techniques and is an excellent opportunity for surgical skill development during residency training. We hypothesized that increasing resident competency, measured as anastomosis time, could be demonstrated while maintaining high-quality surgical outcomes during the learning process.

Methods: We performed a retrospective cohort study of surgical resident involvement in kidney transplantation and recorded the anastomosis time.

Unleashing the Power of NR4A1 Degradation as a Novel Strategy for Cancer Immunotherapy.

An effective cancer therapy requires both killing cancer cells and targeting tumor-promoting pathways or cell populations within the tumor microenvironment (TME). We purposely search for molecules that are critical for multiple tumor-promoting cell types and identified nuclear receptor subfamily 4 group A member 1 (NR4A1) as one such molecule. NR4A1 has been shown to promote the aggressiveness of cancer cells and maintain the immune suppressive TME.

Analytics of self-regulated learning scaffolding: effects on learning processes.

Self-regulated learning (SRL) is the ability to regulate cognitive, metacognitive, motivational, and emotional states while learning and is posited to be a strong predictor of academic success. It is therefore important to provide learners with effective instructions to promote more meaningful and effective SRL processes. One way to implement SRL instructions is through providing real-time SRL scaffolding while learners engage with a task.

Emergence of the Chern Supermetal and Pair-Density Wave through Higher-Order Van Hove Singularities in the Haldane-Hubbard Model.

While advances in electronic band theory have brought to light new topological systems, understanding the interplay of band topology and electronic interactions remains a frontier question. In this work, we predict new interacting electronic orders emerging near higher-order Van Hove singularities present in the Chern bands of the Haldane model. We classify the nature of such singularities and employ unbiased renormalization group methods that unveil a complex landscape of electronic orders, which include ferromagnetism, density waves, and superconductivity.

Inhibition of LILRB2 by a Novel Blocking Antibody Designed to Reprogram Immunosuppressive Macrophages to Drive T-Cell Activation in Tumors.

Tumor-associated macrophages (TAM) play an important role in maintaining the immunosuppressive state of the tumor microenvironment (TME). High levels of CD163+ TAMs specifically are associated with poor prognosis in many solid tumor types. Targeting TAMs may represent a key approach in development of the next generation of cancer immune therapeutics.

Incisional Hernia Development after Live Donor Nephrectomy: Impact of Surgical Technique.

Background: Characteristics of incisional hernia (IH) formation after live donor nephrectomy (LDN) are not well-defined. The goal of this study was to describe the incidence of IH within 3 years after LDN and identify risk factors contributing to their formation.

Methods: We performed a single-center, retrospective review of all LDN between February 2013 and October 2018.

What Can State Medical Boards Do to Effectively Address Serious Ethical Violations?

State Medical Boards (SMBs) can take severe disciplinary actions (e.g., license revocation or suspension) against physicians who commit egregious wrongdoing in order to protect the public.

Unconventional self-similar Hofstadter superconductivity from repulsive interactions.

Fractal Hofstadter bands have become widely accessible with the advent of moiré superlattices, opening the door to studies of the effect of interactions in these systems. In this work we employ a renormalization group (RG) analysis to demonstrate that the combination of repulsive interactions with the presence of a tunable manifold of Van Hove singularities provides a new mechanism for driving unconventional superconductivity in Hofstadter bands. Specifically, the number of Van Hove singularities at the Fermi energy can be controlled by varying the flux per unit cell and the electronic filling, leading to instabilities toward nodal superconductivity and chiral topological superconductivity with Chern number [Formula: see text].

Cocaine sensitizes the CD4 T cells for HIV infection by co-stimulating NFAT and AP-1.

The productive infection of HIV, which generates new viral progeny, depends on the activation status of the cell. In this study, we found cocaine exposure sensitizes partially active CD4 T cells and makes them poised for productive HIV infection. We discovered that cocaine treatment enhances the metabolic state of the cells by co-stimulating several transcription factors, mainly NFAT and AP-1, the two transcription factors, which specifically play a crucial role in enhancing both HIV and the overall cellular gene expression in T cells.

Differential expression of CCR8 in tumors versus normal tissue allows specific depletion of tumor-infiltrating T regulatory cells by GS-1811, a novel Fc-optimized anti-CCR8 antibody.

The presence of T regulatory (Treg) cells in the tumor microenvironment is associated with poor prognosis and resistance to therapies aimed at reactivating anti-tumor immune responses. Therefore, depletion of tumor-infiltrating Tregs is a potential approach to overcome resistance to immunotherapy. However, identifying Treg-specific targets to drive such selective depletion is challenging.

Association between severe anaemia and inflammation, risk of IRIS and death in persons with HIV: A multinational cohort study.

Background: After initiating antiretroviral therapy (ART), approximately 25% of people with HIV (PWH) may develop Immune Reconstitution Inflammatory Syndrome (IRIS), which is associated with increased morbidity and mortality. Several reports have demonstrated that low haemoglobin (Hb) levels are a risk factor for IRIS. To what extent the severity of anaemia contributes to the risk of IRIS and/or death is still insufficiently explored.

Alert-Triggered Patient Education Versus Nurse Feedback for Nonadministered Venous Thromboembolism Prophylaxis Doses: A Cluster-Randomized Controlled Trial.

Background Many hospitalized patients are not administered prescribed doses of pharmacologic venous thromboembolism prophylaxis. Methods and Results In this cluster-randomized controlled trial, all adult non-intensive care units (10 medical, 6 surgical) in 1 academic hospital were randomized to either a real-time, electronic alert-triggered, patient-centered education bundle intervention or nurse feedback intervention to evaluate their effectiveness for reducing nonadministration of venous thromboembolism prophylaxis. Primary outcome was the proportion of nonadministered doses of prescribed pharmacologic prophylaxis.

Nivolumab plus rucaparib for metastatic castration-resistant prostate cancer: results from the phase 2 CheckMate 9KD trial.

Background: CheckMate 9KD (NCT03338790) is a non-randomized, multicohort, phase 2 trial of nivolumab plus other anticancer treatments for metastatic castration-resistant prostate cancer (mCRPC). We report results from cohorts A1 and A2 of CheckMate 9KD, specifically evaluating nivolumab plus rucaparib.

Methods: CheckMate 9KD enrolled adult patients with histologically confirmed mCRPC, ongoing androgen deprivation therapy, and an Eastern Cooperative Oncology Group performance status of 0-1.
