Importance: The current standard-of-care salvage therapy in relapsed/refractory classic Hodgkin lymphoma (cHL) includes consolidation high-dose chemotherapy (HDCT)/autologous stem cell transplant (aSCT).

Objective: To investigate whether presalvage risk factors and fludeoxyglucose-18 (FDG) positron emission tomography (PET) response to reinduction chemotherapy can guide escalation or de-escalation between HDCT/aSCT or transplant-free consolidation with radiotherapy to minimize toxic effects while maintaining high cure rates.

Design, Setting, And Participants: EuroNet-PHL-R1 was a nonrandomized clinical trial that enrolled patients younger than 18 years with first relapsed/refractory cHL across 68 sites in 13 countries in Europe between January 2007 and January 2013.

The HeartMate 3 risk score (HM3RS) was developed from the Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy with HeartMate 3 (MOMENTUM 3) clinical trial to predict 1 and 2 year mortality after left ventricular assist device implantation. However, it has not been validated in a real-world population, especially after the heart transplant allocation system change on October 18, 2018. In this multicenter retrospective analysis, we found that HM3RS did not predict 1 and 2 year outcomes in the contemporary era, highlighting the need to revise this risk prediction tool in the real-world setting.

Background: Within outpatient services, a broad range of innovations are being pursued to better manage care and reduce unnecessary appointments. One of the least-studied innovations is Patient-Initiated Follow-Up, which allows patients to book appointments if and when they need them, rather than follow a standard schedule.

Objectives: To use routine national hospital data to identify innovations in outpatient services implemented, in recent years, within the National Health Service in England.

Article Synopsis
  • The study aimed to understand preferences for care coordination among patients, parents, carers, and healthcare professionals affected by rare diseases in the UK, using online surveys to gather data.
  • A total of 996 valid responses highlighted that all aspects of care coordination, such as cost, access to health records, and support from care coordinators, significantly impacted preferences, with no major differences between patients and carers.
  • However, healthcare professionals showed differing preferences, favoring more autonomy for care coordinators, unlike patients and carers who preferred having greater control over their care coordination.

The COVID-19 pandemic reminded us of the urgent need for new antivirals to control emerging infectious diseases and potential future pandemics. Immunotherapy has revolutionized oncology and could complement the use of antivirals, but its application to infectious diseases remains largely unexplored. Nucleoside analogs are a class of agents widely used as antiviral and anti-neoplastic drugs.

Solid-state spin-photon interfaces that combine single-photon generation and long-lived spin coherence with scalable device integration-ideally under ambient conditions-hold great promise for the implementation of quantum networks and sensors. Despite rapid progress reported across several candidate systems, those possessing quantum coherent single spins at room temperature remain extremely rare. Here we report quantum coherent control under ambient conditions of a single-photon-emitting defect spin in a layered van der Waals material, namely, hexagonal boron nitride.

Article Synopsis
  • The study explores the immune microenvironment of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and its similarities with T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL), focusing on the variations in immune cell types present in different histological patterns.
  • Researchers used advanced imaging techniques to examine how certain immune cells were expanded or depleted in NLPHL cases with various histological features compared to THRLBCL cases.
  • The results revealed significant depletion of T-regulatory cells in NLPHL and an increase in cytotoxic immune cells as the disease progressed, suggesting a connection between NLPHL and THRLBCL and highlighting potential new biomarkers for targeting immune checkpoints in treatment.

Article Synopsis
  • BTK inhibitors (BTKis) represent a major advancement in treating chronic lymphocytic leukemia (CLL) by targeting B-cell signaling and improving immune response.
  • A study compared the effects of ibrutinib-rituximab versus another treatment (FCR) and found that while T-cell counts were reduced with BTKi therapy, the quality of T-cell function and anti-CLL activity actually improved, leading to better patient outcomes.
  • The research suggests combining BTKi treatment with other immunotherapies, like glofitamab, to further enhance T-cell activity against CLL.

Article Synopsis
  • Chronic lymphocytic leukemia (CLL) cells rely heavily on their surrounding tumor microenvironment for growth, making it crucial to explore new treatment options that can boost the immune response.
  • The study focused on interleukin 27 (IL-27), revealing that a lack of IL-27 leads to worse CLL outcomes and creates a more immunosuppressive environment in mouse models.
  • IL-27 not only enhances the activation and effectiveness of CD8+ T cells against CLL in both mice and human samples, but its levels decrease during CLL progression, suggesting it could be an effective treatment option for patients.
