Several chemotherapeutic agents act by increasing DNA damage in cancer cells, triggering cell death. However, there is limited understanding of the extent and long-term consequences of collateral DNA damage in normal tissues. To investigate the impact of chemotherapy on mutation burdens and the cell population structure of normal tissue, we sequenced blood cell genomes from 23 individuals aged 3-80 years who were treated with a range of chemotherapy regimens. Substantial additional somatic mutation loads with characteristic mutational signatures were imposed by some chemotherapeutic agents, but the effects were dependent on the drug and blood cell types. Chemotherapy induced premature changes …

Schizophrenia (SCZ) is a complex psychiatric disorder with unclear biological mechanisms. Spectrins, cytoskeletal proteins linked to neurodevelopmental disorders, are regulated by the AKT/GSK3 pathway, which is implicated in SCZ. However, the impact of SCZ-related dysregulation of this pathway on spectrin expression and distribution remains unexplored. Here, we show that βIV spectrin protein levels were reduced in neurons of the dorsolateral prefrontal cortex in SCZ postmortem samples compared to healthy control (HC) from the Human Brain Collection Core (HBCC). To investigate potential links between βIV spectrin and the AKT/GSK3 pathway, we analyzed the PsychEncode dataset, revealing elevated SPTBN4 and AKT2 mRNA …

Visual acuity, refractive error, angle of deviation, abnormal head posture (AHP), presence of ptosis, prevalence of amblyopia and strabismic patterns were analyzed, with MED eyes compared with fellow eyes.

RESULTS: A total of 105 patients were included. Mean cylindrical refractive error was significantly higher in MED eyes compared with fellow eyes (-1.40 ± 1.70 D …

Purpose: Magrolimab is a monoclonal antibody directed against the macrophage checkpoint CD47 on myeloid leukemia cells that was preclinically synergistic with azacitidine-venetoclax, warranting further clinical evaluation.

Patients and methods: In this phase Ib/II study, the triplet combination of azacitidine, venetoclax, and magrolimab was evaluated in adult patients with first-line (ineligible for intensive chemotherapy) and relapsed/refractory acute myeloid leukemia. Azacitidine was dosed at 75 mg/m2 for 7 days, venetoclax at 400 mg/day for 28 days, and magrolimab (recommended phase II dose) as follows: 1 mg/kg dose on days 1 and 4, 15 mg/kg on day 8, and 30 mg/kg on days …

Purpose: Although detection of ctDNA weeks after surgery is linked to recurrence for other solid tumors, the optimal time point for ctDNA assessment as a prognostic biomarker following chemoradiation for anal cancer is undefined.

Experimental design: Patients with stages I to III anal cancer treated with chemoradiation between December 2020 and March 2024 were evaluated for human papillomavirus (HPV) ctDNA status at baseline, at the end of chemoradiation, and during surveillance using a droplet digital HPV ctDNA PCR assay, targeting HPV E6 and E7 oncogenes for 13 oncogenic HPV types. Median recurrence-free survival (RFS) according to HPV ctDNA status was …

Background: Low-complexity automated nucleic acid amplification tests (LC-aNAATs) are molecular World Health Organization (WHO)-recommended rapid diagnostic tests (also known as mWRDs) widely used to diagnose tuberculosis disease. The lateral flow urine lipoarabinomannan assay (LF-LAM) is recommended by the WHO to assist in diagnosing tuberculosis disease amongst people with HIV. Previous systematic reviews have assessed the diagnostic accuracy of LC-aNAATs and LF-LAM used in isolation for the detection of tuberculosis, but in clinical practice the tests may be used in parallel (i.e. LC-aNAAT in combination with LF-LAM).

Objectives: To compare the diagnostic accuracy of the parallel use of LC-aNAAT on respiratory …
