Performance of ChatGPT-4o in the diagnostic workup of fever among returning travelers requiring hospitalization: a validation study.

Background: Febrile illness in returned travelers presents a diagnostic challenge in non-endemic settings. Chat generative pretrained transformer (ChatGPT) has the potential to assist in medical tasks, yet its diagnostic performance in clinical settings has rarely been evaluated. We conducted a preliminary validation assessment of ChatGPT-4o's performance in the workup of fever in returning travelers.

Advances in Chiral Pincer Complexes: Insights and Applications in Catalytic Asymmetric Reactions.

Chiral pincer complexes, characterized by their rigid tridentate coordination framework, have emerged as powerful catalysts in asymmetric synthesis. This review provides a comprehensive overview of recent advancements in the development of chiral pincer-type ligands and their corresponding transition metal complexes. We highlight the latest progress in their application across a range of catalytic asymmetric reactions, including the (transfer) hydrogenation of polar and non-polar bonds, hydrophosphination, alkynylation, Friedel-Crafts reactions, enantioselective reductive cyclization of alkynyl-tethered cyclohexadienones, enantioselective hydrosilylation, as well as Aza-Morita-Baylis-Hillman reactions.

SARS-CoV-2 Omicron XBB.1 variant outbreak in a defined cohort: an epidemiological investigation incorporating longitudinal assessment of humoral response.

Background: We describe an epidemiological investigation of a SARS-CoV-2-XBB.1 outbreak among healthcare workers (HCWs) returning from a 5-days educational tour abroad.

Methods: We prospectively followed participants for symptoms and sampled blood for neutralization assays of four SARS-CoV-2 variants (wild type, XBB, EG.

Risk factors and correlates of protection against XBB SARS-CoV-2 infection among health care workers.

Correlates of protection for recent emerging SARS-CoV-2 variants have not been determined. In this test-negative case-control study, we report lower odds of infection with XBB variants among those boosted during the last six months. Additionally, we demonstrate that XBB-specific neutralizing antibodies are independent correlates of protection.

Hard Successive Interference Cancellation for M-QAM MIMO Links in the Presence of Rayleigh Deep-Fading.

In our paper, we propose a generalized version of the Alternating Projections Digital Hard Successive Interference Cancellation (AP-HSIC) algorithm that is capable of decoding any order of constellation M in an M-Quadrature Amplitude Modulation (QAM) system. Our approach applies to Rayleigh deep-fading Multiple-Input Multiple-Output (MIMO) channels with high-level Additive White Gaussian Noise (AWGN). It can handle various destructive phenomena without restricting the number of antenna arrays in the transmitter/receiver.
