Germline BRCA pathogenic variants and hematologic adverse events in patients with ovarian carcinoma receiving PARP inhibitors: a retrospective cohort study.

Background: Patients with a germline BRCA pathogenic variant (gBRCA-PV) and advanced high grade ovarian carcinoma (aHGOC) experience higher hematologic adverse events (HAEs) when receiving platinum salts and ionizing radiations, compared to non-carriers, due to a possible higher susceptibility of the hemopoietic stem cells to DNA targeting agents. However, the incidence of PARP inhibitor (PARPi)-related HAEs according to the gBRCA-PV status is currently unknown.

Patients And Methods: We conducted a single-center retrospective cohort study to describe the occurrence of HAEs in patients with aHGOC receiving ≥8 weeks of maintenance PARPi in any line of therapy, comparing gBRCA-PVs carriers to non-carriers.

Probing hidden leptonic scalar portals using the NA64 experiment at CERN.

In this study, we demonstrate the potential of the NA64 experiment at CERN SPS to search for New Physics processes involving transitions after the collision of 100 GeV electrons with target nuclei. A new Dark Sector leptonic portal in which a scalar boson could be produced in the lepton-flavor-changing bremsstrahlung-like reaction, , is used as benchmark process. In this work, we develop a realistic Monte Carlo simulation of the NA64 experimental setup implementing the differential and total production cross-section computed at exact tree-level and applying the Weiszäcker-Williams phase space approximation.

Dark-Sector Search via Pion-Produced η and η^{'} Mesons Decaying Invisibly in the NA64h Detector.

We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η^{'} mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π^{-} on nuclei of an active target as the source of neutral mesons. The η,η^{'}→invisible events would exhibit themselves via a striking signature-the complete disappearance of the incoming beam energy in the detector.

Advanced CMOS manufacturing of superconducting qubits on 300 mm wafers.

The development of superconducting qubit technology has shown great potential for the construction of practical quantum computers. As the complexity of quantum processors continues to grow, the need for stringent fabrication tolerances becomes increasingly critical. Utilizing advanced industrial fabrication processes could facilitate the necessary level of fabrication control to support the continued scaling of quantum processors.

Germline BRCA pathogenic variants in patients with ovarian cancer and post-poly (ADP-ribose) polymerase inhibitor myeloid neoplasms.

Background: Among patients with advanced high-grade ovarian carcinoma (aHGOC) treated with poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis), the presence of a germline BRCA pathogenic variant (gBRCA-PV) may increase the risk of bone marrow mutagenesis resulting in postcytotoxic therapy myelodysplastic neoplasms (MDS-pCT) or acute myeloid leukemia (AML-pCT), as it is expressed in heterozygosity also by hematopoietic progenitors. We aimed to investigate the occurrence of post-PARPi MDSs/AMLs-pCTs according to gBRCA-PV status.

Patients And Methods: We conducted a retrospective single-center study to evaluate MDS/AML-pCT in patients with aHGOC and a known gBRCA-PV status receiving at least 8 weeks of maintenance PARPi, in any line of therapy, from February 2017 to December 2022.
