Introduction: The renin-angiotensin system (RAS) has been demonstrated to modulate cell proliferation, desmoplasia, angiogenesis and immunosuppression. We examined the association of RAS inhibitors (RASi)-namely angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB)-with neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) preceding radical cystectomy (RC).

Patients And Methods: We retrospectively investigated concurrent RASi use with NAC prior to RC in 302 patients with MIBC from 3 academic institutions.

Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics, and photon pressure systems. Here, we engineer a microwave mode in a superconducting LC circuit that mimics the dynamics of a negative mass oscillator, and couple it via photon pressure to a second low-frequency circuit. We demonstrate that the effective negative mass dynamics lead to an inversion of dynamical backaction and to sideband cooling of the low-frequency circuit by a blue-detuned pump field, which can be intuitively understood by the inverted energy ladder of a negative mass oscillator.

Microwave driving is a ubiquitous technique for superconducting qubits, but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these approximations applicable to transmon-based circuit quantum electrodynamics (QED) systems are unfortunately rare, as the relevant works have been mainly limited to single-mode or two-state systems. In this work, we investigate a microwave-dressed transmon coupled to a single quantized mode over a wide range of driving parameters.

Nonlinear damping, the change in damping rate with the amplitude of oscillations plays an important role in many electrical, mechanical and even biological oscillators. In novel technologies such as carbon nanotubes, graphene membranes or superconducting resonators, the origin of nonlinear damping is sometimes unclear. This presents a problem, as the damping rate is a key figure of merit in the application of these systems to extremely precise sensors or quantum computers.

Introduction: Retroperitoneal lymph node dissection (RPLND) is the standard of care for testicular cancer in various disease settings. Deep vein thrombosis (DVT) complications have been reported to occur in <1% of primary RPLND cases and up to 3% of postchemotherapy (PC-RPLND) cases. While prophylactic anticoagulation (AC) has been well-documented to reduce DVT rates in patients undergoing surgery in general, the benefit of prophylactic AC in RPLND has not been assessed.

Radical cystectomy (RC) is an integral part of the management of patients with advanced-stage bladder cancer. This major oncologic operation is prone to complications resulting in morbidity and mortality. We analyzed the critical steps of open RC, performed an evidence-based review of these steps, and discussed our experience and approach.

Bone and joint infections (BJIs) are common infections increasingly managed with oral therapy. However, there are limited safe oral options for many Gram-positive pathogens. In animal studies and short-term human use, tedizolid lacks the hematologic and neurologic toxicity of the other available oxazolidinone, linezolid.

Background: Real-world data on racial differences in the side effects of radical prostatectomy on quality of life (QoL) are lacking. We aimed to evaluate differences in patient-reported outcome measure (PROM) among non-Hispanic Black (NHB) and non-Hispanic White (NHW) men using the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) questionnaire to measure health-related QoL after radical prostatectomy.

Methods: We retrospectively assessed prospectively collected PROMs using EPIC-CP scores at a tertiary care center between 2015 and 2021 for men with prostate cancer undergoing radical prostatectomy.

Purpose: Bacillus Calmette-Guerin (BCG) is the standard of care for high-risk nonmuscle invasive bladder cancer (NMIBC), but half of patients develop disease recurrence. Intravesical regimens for BCG unresponsive NMIBC are limited. We report the safety, efficacy, and differential response of sequential gemcitabine/docetaxel (gem/doce) depending on BCG failure classification.

Background: This study compared dalbavancin with standard of care (SOC) for patients with Staphylococcus aureus bacteraemia (SAB) who were unable to receive outpatient parenteral antimicrobial therapy (OPAT).

Methods: This retrospective cohort compared re-admission rates related to the index infection between patients treated with dalbavancin or SOC for SAB. Patients aged ≥18 years seen by the infectious diseases consult service who had received at least one dose of dalbavancin or at least 1 week of SOC parenteral antibacterials as directed therapy for SAB at the time of discharge were included.

Quantum materials can display physical phenomena rooted in the geometry of electronic wavefunctions. The corresponding geometric tensor is characterized by an emergent field known as the Berry curvature (BC). Large BCs typically arise when electronic states with different spin, orbital or sublattice quantum numbers hybridize at finite crystal momentum.

Article Synopsis
  • The purpose of the systematic review was to investigate racial and ethnic disparities in access to germline genetic testing (GGT) for prostate cancer among Black men and other marginalized groups, as this testing is important for cancer risk assessment and treatment.
  • The review analyzed studies published between 1996 and 2021, finding that of 91 studies, only a small number (4) reflected GGT rates in routine clinical care, showing a significant underrepresentation of Black men compared to White men.
  • The conclusion highlights that most GGT data comes from research settings rather than clinical practice and that there's a lack of representation for other marginalized populations, indicating a significant gap in understanding racial disparities in GGT usage.

Photon-pressure coupling between two superconducting circuits is a promising platform for investigating radiation-pressure coupling in distinct parameter regimes and for the development of radio-frequency (RF) quantum photonics and quantum-limited RF sensing. Here, we implement photon-pressure coupling between two superconducting circuits, one of which can be operated as a parametric amplifier. We demonstrate a Kerr-based enhancement of the photon-pressure single-photon coupling rate and an increase of the cooperativity by one order of magnitude in the amplifier regime.

Quantum information processing requires fast manipulations of quantum systems in order to overcome dissipative effects. We propose a method to accelerate quantum dynamics and obtain a target state in a shorter time relative to unmodified dynamics, and apply the theory to a system consisting of two linearly coupled qubits. We extend the technique to accelerate quantum adiabatic evolution in order to rapidly generate a desired target state, thereby realizing a shortcut to adiabaticity.

SARS-CoV-2 may activate both innate and adaptive immune responses ultimately leading to a dysregulated immune response prompting the use of immunomodulatory therapy. Although viral pneumonia increases the risk of invasive fungal infections, it remains unclear whether SARS-CoV-2 infection, immunomodulatory therapy, or a combination of both are responsible for the increased recognition of opportunistic infections in COVID-19 patients. Cases of cryptococcosis have previously been reported following treatment with corticosteroids, interleukin (IL)-6 inhibitors, and Janus kinase (JAK) inhibitors, for patients with autoimmune diseases, but their effect on the immunologic response in patients with COVID-19 remains unknown.

Quantum control of electromagnetic fields was initially established in the optical domain and has been advanced to lower frequencies in the gigahertz range during the past decades extending quantum photonics to broader frequency regimes. In standard cryogenic systems, however, thermal decoherence prevents access to the quantum regime for photon frequencies below the gigahertz domain. Here, we engineer two superconducting circuits coupled by a photon-pressure interaction and demonstrate sideband cooling of a hot radio frequency (RF) circuit using a microwave cavity.

We have studied 1/f noise in critical current [Formula: see text] in h-BN encapsulated monolayer graphene contacted by NbTiN electrodes. The sample is close to diffusive limit and the switching supercurrent with hysteresis at Dirac point amounts to [Formula: see text] nA. The low frequency noise in the superconducting state is measured by tracking the variation in magnitude and phase of a reflection carrier signal [Formula: see text] at 600-650 MHz.
