Predictive signatures of immune response to vaccination and implications of the immune setpoint remodeling.

In 2020, I featured two articles in the "mSphere of Influence" commentary series that had profound implications for the field of immunology and helped shape my research perspective. These articles were "Global Analyses of Human Immune Variation Reveal Baseline Predictors of Postvaccination Responses" by Tsang et al. (Cell 157:499-513, 2014, https://doi.

Unveiling the potential role of the shock index in maternal sepsis: reality or fantasy?

Objective: Maternal sepsis continues to be a maternal health problem associated with 75,000 deaths per year worldwide, representing a greater burden in low- and middle-income countries (LMICs). Although the Shock Index (SI) has been widely studied in postpartum hemorrhage and in non-obstetric populations, it has not yet been widely studied in sepsis. We aimed to identify the relationship between Shock Index and suspected sepsis in pregnant and postpartum patients to explore the use of Shock index in the context of maternal sepsis and its relationship with sepsis-related outcomes.

New Potent Inhibitor of Transforming Growth Factor-Beta (TGFβ) Signaling that is Efficacious against Microsatellite Stable Colorectal Cancer Metastasis in Combination with Immune Checkpoint Therapy in Mice.

Blockade of the TGFβ signaling pathway has emerged from preclinical studies as a potential treatment to enhance the efficacy of immune checkpoint inhibition in advanced colorectal cancer (CRC) and several other types of cancer. However, clinical translation of first-generation inhibitors has shown little success. Here, we report the synthesis and characterization of HYL001, a potent inhibitor of TGFβ receptor 1 (ALK5), that is approximately 9 times more efficacious than the structurally related compound galunisertib, while maintaining a favorable safety profile.

Nursing students and the internet: a reflection of digital ethics.

Objectives: to identify how first-year nursing students use cyberspace and propose an orientation guide with criteria guiding the use of cyberspace.

Methods: qualitative and descriptive research, carried out with 24 nursing students from a federal public institution in Rio de Janeiro. Data collection was carried out through semi-structured interviews.

The Importance of Cellular Therapy in the Clinical Case of a Young Man With a Challenging Precursor B-cell Lymphoblastic Leukemia.

Acute lymphoblastic leukemia (ALL) poses a significant challenge due to its high relapse rate despite initial chemotherapy. Cell therapy plays an important and promising role in refractory ALL cases. The aim is to present a complex case of a 20-year-old male patient with relapsed ALL and to explore the different therapeutic options of cellular therapy - allogeneic hematopoietic stem cell transplantation, donor lymphocyte infusion, and chimeric antigen receptor T - detailing the collection, processing, and infusion, as well as the associated complications and management strategies.
