Introduction: Antibody-drug conjugates (ADCs) trastuzumab-deruxtecan (T-DXd) and sacituzumab-govitecan (SG) provided significant progression-free survival (PFS) and overall survival (OS) improvements over chemotherapy (CT) in pretreated hormone receptor-positive (HR+) and triple-negative (TN)/HER2-low metastatic breast cancer (MBC). However, no direct comparison between the two exists, nor with the more recent datopotamab-deruxtecan (Dato-DXd).
Methods: We conducted a network meta-analysis (NMA) to compare efficacy and safety of T-DXd and SG in CT-pretreated HR+ and TN/HER2-low MBC and assess their benefit over standard CT, exploring also a comparison with Dato-DXd.

Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated in 1997 with the goal of updating the Arctic Ocean bathymetric portrayal.

Point-of-care abdominal ultrasound (US) has emerged as a powerful tool for clinicians and is becoming a routine bedside tool to rapidly diagnose, manage hemodynamics, monitor fluid status, and guide procedures in emergency and critical care. Extended focused assessment with sonography for trauma (eFAST), is commonly used to detect free intraperitoneal blood in the trauma setting and may also be an option in non-trauma patients. However, it has significant limitations for detecting gastrointestinal or retroperitoneal bleeding.

The maintenance of stable allograft status in the absence of immunosuppression, known as operational tolerance, can be achieved in a small proportion of liver transplant recipients, but we lack reliable tools to predict its spontaneous development. We conducted a prospective, multi-center, biomarker-strategy design, immunosuppression withdrawal clinical trial to determine the utility of a predictive biomarker of operational tolerance. The biomarker test, originally identified in a patient cohort with high operational tolerance prevalence, consisted of a 5-gene transcriptional signature measured in liver tissue collected before initiating immunosuppression weaning.

The collection of Homo sapiens anatomical hallmarks hypothesized to support the 'human condition' did not appear at one specific time and place, but gradually, creating a reticulate evolutionary trajectory. The recent reconstruction of migration patterns and gene flows across different hominin species and populations draws a mosaic that we contend can be illuminated by genomic comparisons and specific experiments. Here, we first review key discoveries that could allow this experimental endeavor by describing recent advances in a variety of fields, stressing the importance of charting the current human neurodiversity as an interpretive substrate for evolutionary changes.

Objective: Endocervical curettage (ECC) is the gold standard for predicting the persistence of high-grade squamous intraepithelial lesions (HSIL) after cervical conization. However, ECC has a high rate of unsatisfactory samples and may be uncomfortable for women. Endocervical sampling with brush (ECB) has been proposed as an alternative to ECC, which, in addition to the cytological evaluation, allows performing HPV testing using the same sample.

Background: The complex aetiology of type 1 diabetes (T1D), characterised by a detrimental cross-talk between the immune system and insulin-producing beta cells, has hindered the development of effective disease-modifying therapies. The discovery that the pharmacological activation of LRH-1/NR5A2 can reverse hyperglycaemia in mouse models of T1D by attenuating the autoimmune attack coupled to beta cell survival/regeneration prompted us to investigate whether immune tolerisation could be translated to individuals with T1D by LRH-1/NR5A2 activation and improve islet survival.
Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from individuals with and without T1D and derived into various immune cells, including macrophages and dendritic cells.
The Gadolinium Research and Education Committee (GREC) is a working group of the European Society for Magnetic Resonance in Medicine and Biology (ESMRMB), established in 2016. The aim of the committee is to monitor scientific evidence for a continuous quality and safety improvement of enhanced MRI using gadolinium-based contrast agents (GBCAs), and also assess potential alternatives. The scope of the present article is to describe the level of evidence concerning safety beyond the single patient (access to community and environmental impact), justification and optimization of the use of GBCAs beyond dosage (appropriateness and influence on clinical decision making), dose reduction with the use of AI (benefits and pitfalls), the advent of next-generation GBCAs (based on currently available data).

Batteries based on sulfur cathodes offer a promising energy storage solution due to their potential for high performance, cost-effectiveness, and sustainability. However, commercial viability is challenged by issues such as polysulfide migration, volume changes, uneven phase nucleation, limited ion transport, and sluggish sulfur redox kinetics. Addressing these challenges requires insights into the structural, morphological, and chemical evolution of phases, the associated volume changes and internal stresses, and ion and polysulfide diffusion within the battery.

Schizophrenia is a complex multifactorial disorder and increasing evidence suggests the involvement of immune dysregulations in its pathogenesis. We observed that IKZF1 and IKZF2, classic immune-related transcription factors (TFs), were both downregulated in patients' peripheral blood mononuclear cells (PBMCs) but not in their brain. We generated a new mutant mouse model with a reduction in Ikzf1 and Ikzf2 to study the impact of those changes.
