Objectives: Survivors of intracerebral haemorrhage (ICH) are at high risk of incident depression, which is modified by social determinants of health (SDOH) and associated with worse functional outcomes. We sought to determine the role of prestroke SDOH in depression incidence after ICH to better characterise post-ICH outcomes.

Study Design: We analysed data from a cohort study of ICH survivors without prestroke depression, presenting at Massachusetts General Hospital between 2006 and 2017.

Shake effects, resulting from sudden core potential changes during photoexcitation, are well-known in X-ray photoelectron spectroscopy (XPS) and often produce satellite peaks due to many-body excitations. It has been thought, however, that they are negligible in core-to-core X-ray emission spectroscopy (CTC-XES), where the difference in core-hole potentials upon radiative decay is rather small. We demonstrate that shake effects are significant in Kα XES from 3d transition metal systems with nominally zero valence electrons.

Background: Glofitamab monotherapy induces durable remission in patients with relapsed or refractory diffuse large B-cell lymphoma after two or more previous therapies, but has not previously been assessed as a second-line therapy. We investigated the efficacy and safety of glofitamab plus gemcitabine-oxaliplatin (Glofit-GemOx) versus rituximab (R)-GemOx in patients with relapsed or refractory diffuse large B-cell lymphoma.

Methods: The phase 3, randomised, open-label STARGLO trial was done at 62 centres in 13 countries in Asia and Australia, Europe, and North America.

Article Synopsis
  • The voltage-dependent anion channel (VDAC) is a key protein in mitochondria that helps exchange ions and metabolites with the cytosol, and its structure was first defined in 2008.
  • The recent study presents a new crystal structure of mouse VDAC-1 at room temperature, revealing differences in its loop regions compared to previous cryogenic images, which may be vital for how VDAC-1 opens and closes.
  • The research suggests using electric field-stimulated X-ray crystallography (EF-X) to study the 'closed' state of VDAC-1, aiming to better understand its dynamic gating mechanism and overall role in mitochondrial functions.

Lymphomatous infiltration of the peripheral nervous system (PNS), termed neurolymphomatosis, represents a distinct extranodal non-Hodgkin lymphoma variant with dismal outcome. CD19-directed chimeric antigen receptor (CD19-CAR) T-cell therapy has emerged as a safe and effective treatment for B-cell lymphomas. We aimed to assess toxicity and efficacy of CD19-CAR T-cells in neurolymphomatosis.

TP53-mutant mantle cell lymphoma (MCL) is associated with poor survival outcomes with standard chemoimmunotherapy. Dual BTK and BCL2-inhibition with or without anti-CD20 monoclonal antibody therapy has shown promising activity in TP53-mutant MCL. We conducted a multi-center phase 2 study of zanubrutinib, obinutuzumab, and venetoclax (BOVen) in untreated MCL patients with TP53 mutation.

Article Synopsis
  • Double-hit lymphoma (DHL) is a high-risk type of large B-cell lymphoma characterized by specific genetic rearrangements and is diagnosed using histology, immunophenotyping, and FISH techniques.
  • * DHL can vary in appearance and is typically of the germinal center B-cell type, with prognosis affected by factors like elevated LDH levels and disease stage.
  • * Advances in treatment, including intensive chemotherapy and innovative therapies like CAR-T cells, show promise for improving outcomes, especially in cases that are resistant to standard therapies.

The ECHELON-1 trial demonstrated the effectiveness of brentuximab vedotin (BV) in combination with doxorubicin, vinblastine, and dacarbazine as a frontline treatment regimen in classical Hodgkin lymphoma. However, peripheral neuropathy (PN) is common with this regimen, occurring in up to two-thirds of patients. While standard prescribing information recommends BV dose modification at the onset of grade 2 PN, management strategies for PN are not well-defined.

Article Synopsis
  • Deficient DNA mismatch repair (dMMR) serves as a biomarker indicating a better response to PD-1 blockade immunotherapy in solid tumors, including diffuse large B-cell lymphoma (DLBCL).
  • In a study involving a large cohort of DLBCL patients, genetic dMMR was found infrequently and linked to a more favorable immune microenvironment but did not show a strong prognostic impact.
  • Additionally, while phenotypic dMMR was also rare, its presence correlated with increased T cell activity, suggesting that PD-1 T cells may selectively target tumor cell subsets with dMMR, which has implications for the efficacy of immunotherapy in DLBCL.

An unmet need exists for patients with relapsed/refractory (R/R) follicular lymphoma (FL) and high-risk disease features, such as progression of disease within 24 months (POD24) from first-line immunochemotherapy or disease refractory to both CD20-targeting agent and alkylator (double refractory), due to no established standard of care and poor outcomes. Chimeric antigen receptor (CAR) T cell therapy is an option in R/R FL after two or more lines of prior systemic therapy, but there is no consensus on its optimal timing in the disease course of FL, and there are no data in second-line (2L) treatment of patients with high-risk features. Lisocabtagene maraleucel (liso-cel) is an autologous, CD19-directed, 4-1BB CAR T cell product.

Introduction: Intracerebral hemorrhage (ICH) is attributable to cerebral small vessel disease (cSVD), which includes cerebral amyloid angiopathy (CAA) and hypertensive-cSVD (HTN-cSVD). HTN-cSVD includes patients with strictly deep ICH/microbleeds and mixed location ICH/microbleeds, the latter representing a more severe form of HTN-cSVD. We test the hypothesis that more severe forms of HTN-cSVD are related to worse hypertension control in long-term follow-up after ICH.

The introduction of AlphaFold 2 has spurred a revolution in modelling the structure of proteins and their interactions, enabling a huge range of applications in protein modelling and design. Here we describe our AlphaFold 3 model with a substantially updated diffusion-based architecture that is capable of predicting the joint structure of complexes including proteins, nucleic acids, small molecules, ions and modified residues. The new AlphaFold model demonstrates substantially improved accuracy over many previous specialized tools: far greater accuracy for protein-ligand interactions compared with state-of-the-art docking tools, much higher accuracy for protein-nucleic acid interactions compared with nucleic-acid-specific predictors and substantially higher antibody-antigen prediction accuracy compared with AlphaFold-Multimer v.

STOP-CA was a multicenter, double-blind, randomized, placebo-controlled trial comparing atorvastatin to placebo in treatment-naïve lymphoma patients receiving anthracycline-based chemotherapy. We performed a preplanned subgroup to analyze the impact of atorvastatin on efficacy in patients with diffuse large B-cell lymphoma (DLBCL). Patients received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) at standard doses for six 21-day cycles and were randomly assigned to receive atorvastatin 40 mg daily ( = 55) or placebo ( = 47) for 12 months.
