Abstract

This article discusses a retrospective study conducted on 26 cases of anti-myelin-associated glycoprotein (anti-MAG) neuropathy, a rare condition characterized by a slowly progressive demyelinating sensory-motor polyneuropathy. The study aimed to evaluate the efficacy of rituximab, a monoclonal antibody, in combination with an alkylating agent in treating this condition. The results showed that treatment with rituximab and an alkylating agent was safe and effective, with 71% of patients showing improvement in their neuropathy symptoms. The study suggests that aggressively targeting the production of anti-MAG antibodies may be crucial in preventing disabling neuropathies. Further research is needed to assess the effectiveness of this treatment approach in larger randomized trials. [Extracted from the article]

Abstract

Sharing information coherently between nodes of a quantum network is fundamental to distributed quantum information processing. In this scheme, the computation is divided into subroutines and performed on several smaller quantum registers that are connected by classical and quantum channels.sup.1. A direct quantum channel, which connects nodes deterministically rather than probabilistically, achieves larger entanglement rates between nodes and is advantageous for distributed fault-tolerant quantum computation.sup.2. Here we implement deterministic state-transfer and entanglement protocols between two superconducting qubits fabricated on separate chips. Superconducting circuits.sup.3 constitute a universal quantum node.sup.4 that is capable of sending, receiving, storing and processing quantum information.sup.5-8. Our implementation is based on an all-microwave cavity-assisted Raman process.sup.9, which entangles or transfers the qubit state of a transmon-type artificial atom.sup.10 with a time-symmetric itinerant single photon. We transfer qubit states by absorbing these itinerant photons at the receiving node, with a probability of 98.1 [plus or minus] 0.1 per cent, achieving a transfer-process fidelity of 80.02 [plus or minus] 0.07 per cent for a protocol duration of only 180 nanoseconds. We also prepare remote entanglement on demand with a fidelity as high as 78.9 [plus or minus] 0.1 per cent at a rate of 50 kilohertz. Our results are in excellent agreement with numerical simulations based on a master-equation description of the system. This deterministic protocol has the potential to be used for quantum computing distributed across different nodes of a cryogenic network.Deterministic quantum state transfer and entanglement generation is demonstrated between superconducting qubits on distant chips using single photons., Author(s): P.

Abstract

Purpose: to assess overranging (OR) as a function of pitch, collimation and rotation time for three commonly used CT models in France. Methods: OR was measured using XR-SP2 Gafchromic films (Ashland, USA) and computed from exposure data for three widely used CT models in France. The impact of collimation, pitch and rotation time on OR was analyzed while comparing the three CT models. Results: for a typical head protocol, measured OR was found to be equal to 1.64 cm for CT scan A, 0.5 cm for CT scan B and 3.44 cm for CT scan C. OR values were respectively of 4.47, 3.24 and 7.81 cm for the typical chest protocol and the 3 CT models. OR was lowest at pitch values <1 for CT scan A, while it linearly increased with pitch for CT scan B and was lowest for high pitch values for CT scan C. Additionally, OR increase with collimation (24 mm to 38.4 mm) was most pronounced for CT scan B (factor of 2.2 for low pitch (0.5) and 2.8 for high pitch (1.2)) while it increased linearly regardless of the pitch for CT scans A and C. Rotation time also proved to slightly affect OR mainly for CT scan B (up to 2.2 mm). Conclusion: the present study shows that overranging remains an issue in modern CT scanners with large disparities across the vendors. [ABSTRACT FROM AUTHOR]

Abstract

Objective: Active surveillance of cytologically proven microcarcinomas has been shown as a safe procedure. However, fine needle aspiration biopsy (FNAB) is not recommended by European Thyroid Association (ETA) and American Thyroid Association (ATA) guidelines for highly suspicious nodules ≤ 10 mm. The aim of the study was to assess the outcomes of active surveillance of EU-TIRADS 5 nodules ≤ 10 mm not initially submitted to FNAB. Patients and methods: 80 patients with at least one EU-TIRADS 5 nodule ≤ 10 mm and no suspicious lymph nodes, accepting active surveillance, were included. Results: Mean baseline diameter and volume were 5.4 mm (±2.0) and 64.4 mm³ (±33.5), respectively. After a median follow-up of 36.1 months, a volumetric increase ≥ 50% occurred in 28 patients (35.0%) and a suspicious lymph node in 3 patients (3.8%). Twenty-four patients underwent an FNAB (30.0%) after at least a 1 year follow-up of which 45.8% were malignant, 8.3% benign, 33.3% undetermined and 8.3% nondiagnostic. Sixteen patients (20.0%) underwent conversion surgery after a median follow-up of 57.2 months, confirming the diagnosis of papillary carcinoma in 15/16 cases (not described in 1 histology report), all in remission at 6–12 months postoperative follow-up. Conclusion: Applying ETA and ATA guidelines to avoid FNA of EU-TIRADS 5 sub-centimeter nodules and proceeding to active surveillance of such nodules in selected patients is a safe procedure. Thus, US-FNAB could be postponed until the nodule shows signs of progression or a suspicious lymph node appears, with no added risk for the patient. [ABSTRACT FROM AUTHOR]
