Hardware-efficient quantum error correction via concatenated bosonic qubits.

To solve problems of practical importance, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead associated with error correction motivates the search for more hardware-efficient approaches. Here, using a superconducting quantum circuit, we realize a logical qubit memory formed from the concatenation of encoded bosonic cat qubits with an outer repetition code of distance d = 5 (ref.

Management of Postpartum Preeclampsia and Hypertensive Disorders (MOPP): Postpartum Tight vs Standard Blood Pressure Control.

Background: It is unknown whether tightly controlled blood pressure in the postpartum period will improve outcomes.

Objectives: The purpose of this study was to assess the effect of a lower treatment threshold (≥130/80 mm Hg) for initiating and titrating antihypertensive medication on reducing emergency department visits in postpartum patients with hypertension.

Methods: A prospective cohort of postpartum patients was recruited in a multicenter study between March 2023 and March 2024 and treated to maintain blood pressure <130/80 mm Hg using remote blood pressure monitoring.

Clinical Characteristics of Patients With Kabuki Syndrome at a Single Tertiary Children's Hospital.

Kabuki syndrome (KS) is a multisystem disorder characterized by facial dysmorphic features, growth delays, skeletal anomalies, and variable intellectual disability (ID) due to pathogenic variants in KMT2D and KDM6A. Significant phenotypic variability has been reported in patients with KS. To further characterize the variability observed in the genomic sequencing era, comprehensive genotypic and phenotypic information from 36 patients with KS and likely pathogenic or pathogenic KMT2D or KDM6A variants at the Children's Hospital of Philadelphia (CHOP) was collected.

Systemic risk factors contributing to sialolithiasis: a big-data retrospective analysis.

Aims: To investigate systemic risk factors contributing to the formation of sialolithiasis.

Methods: A retrospective big-data cohort study was conducted using data from Clalit HMO in Israel. Sialolithiasis patients were identified based on ICD-10 codes and matched with controls.

Hospitalization for cardiovascular disease in the year after delivery of twin pregnancies.

Background And Aims: Increased cardiovascular demand in twin pregnancies, even those without hypertensive disease of pregnancy (HDP), may pose a greater risk for cardiovascular complications compared with singletons. In this study, the risk of cardiovascular disease (CVD)-related hospitalizations and mortality within the year following delivery in relation to HDP was compared between twin and singleton pregnancies.

Methods: Using the Nationwide Readmissions Database of US hospitals from 2010 to 2020, the rates of CVD readmission in four exposure groups (twin deliveries with and without HDP and singleton deliveries with and without HDP) were estimated.
