Comparative Outcomes of Babesiosis in Immunocompromised and Non-Immunocompromised Hosts: A Multicenter Cohort Study.

Background: Babesiosis poses significant risks of adverse outcomes in individuals with immunocompromising conditions (IC) and asplenia/hyposplenia (AH). This study compares clinical outcomes between these vulnerable groups and immunocompetent patients.

Methods: A multicenter retrospective cohort study included adult patients with laboratory-confirmed babesiosis from 2009 to 2023.

Phosphine Oxide Indenoquinoline Derivatives: Synthesis and Biological Evaluation as Topoisomerase I Inhibitors and Antiproliferative Agents.

The synthesis of phosphorous indenoquinolines and their biological evaluation as topoisomerase 1 (TOP1) inhibitors and antiproliferative agents were performed. First, the preparation of new hybrid 5-indeno[2,1-]quinolines with a phosphine oxide group was performed by a two-step Povarov-type [4+2]-cycloaddition reaction between the corresponding phosphorated aldimines with indene in the presence of BF·EtO. Subsequent oxidation of the methylene present in the structure resulted in the corresponding indeno[2,1-]quinolin-7-one phosphine oxides .

Early versus late infectious complications following chimeric antigen receptor-modified T-cell therapy.

Despite increasing utilization of CAR T-cell therapy, data are lacking regarding long term follow up and risk of infectious complications after the early period following CAR T-cell infusion. In this study, we sought to compare epidemiology and risk factors for early (≤ 3 months) and late (3 months to 1 year) infections. Data were retrospectively collected at six time points: pre-CAR T, day of infusion, and at 3, 6, 9, and 12 months post CAR-T infusion for all consecutive adult patients treated at our institution.

Novel replication-competent reporter-expressing Rift Valley fever viruses for molecular studies.

Unlabelled: Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic disease that causes severe disease in both domestic and wild ungulates and humans, making it a significant threat to livestock and public health. The RVFV genome consists of three single-stranded, negative-sense RNA segments differing in size: small (S), medium (M), and large (L). Segment S encodes the virus nucleoprotein N and the virulence-associated factor non-structural (NSs) protein in opposite orientations, separated by an intergenic region (IGR).

Antibiotic-Resistant from Market Meat in Peru.

Unconsidered microorganisms, such as may be often recovered from food samples. This study aimed to characterize seven recovered from traditional market chicken meat in Lima, Peru. Antimicrobial susceptibility to 18 antimicrobial agents as well as the presence of amino acid changes in fluoroquinolone targets, 10 mediated colistin resistance () genes and integrons were analyzed.
