Detection of clinically relevant variants in the gene below 10% allelic frequency: A multicenter study by ERIC, the European Research Initiative on CLL.

In chronic lymphocytic leukemia, the reliability of next-generation sequencing (NGS) to detect variants ≤10% allelic frequency (low-VAF) is debated. We tested the ability to detect 23 such variants in 41 different laboratories using their NGS method of choice. The sensitivity was 85.

Characterization of Chitinase 3-like protein 1 spatiotemporal distribution in human post-traumatic brain contusions and other neuropathological scenarios.

Chitinase 3-like protein 1 (CHI3L1) is emerging as a promising biomarker for assessing intracranial lesion burden and predicting prognosis in traumatic brain injury (TBI) patients. Following experimental TBI, Chi3l1 transcripts were detected in reactive astrocytes located within the pericontusional cortex. However, the cellular sources of CHI3L1 in response to hemorrhagic contusions in human brain remain unidentified.

Human Cytomegalovirus Infection Induces Long-Term Changes in the Cytokine Milieu of Kidney Transplant Recipients.

The impact of human cytomegalovirus (HCMV) infection on the mid- and long-term balance between pro-inflammatory and anti-inflammatory cytokines among kidney transplant recipients (KTRs) remains unclear. We measured plasma levels of 12 Th1/Th2-type cytokines (granulocyte-macrophage colony-stimulating factor, interferon-γ, interleukin [IL]-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p70, IL-13, IL-18 and tumor necrosis factor-α) in a cohort of 290 KTRs at four time points through month 12 after transplantation. Cytokine levels at each point were compared according to the previous documentation of HCMV replication by two approaches: "cumulative exposure" from the time of transplantation and "recent exposure" within the 2-3 months preceding cytokine assessment.

Electrophisiological monitoring of pain in non-communicative critically ill patients.

Electrophysiological monitoring of pain provides objective measures that allow for pain control and adjustment of analgesia in non-communicative patients. Among the available electrophysiological devices, automated infrared pupillometry, Analgesia Nociception Index (ANI), and Nociception Level Index (NOL®) stand out. These non-invasive measurement systems analyze the sympathetic or parasympathetic nervous system response to painful stimuli by observing pupillary dilatation and reactivity (pupillometry), heart rate during respiration (ANI), or a combination of multiple parameters from the nociceptive-autonomic medullary circuit (NOL®).

Newly identified cell types crucial for gut commensal tolerance.

The generation of regulatory T cells (Tregs) through interactions with antigen-presenting cells (APCs) is essential for establishing tolerance to gut commensals. Recent findings highlight the critical role of RORγt-lineage APCs, especially in gut-associated lymphoid tissues, in the induction of microbiota-specific peripheral Tregs and maintaining gut immune homeostasis.

The impact of blood eosinophil count and FeNO on benralizumab effectiveness in clinical practice: An ORBE II subanalysis.

Background: The ORBE II study showed the real-world effectiveness of benralizumab in severe eosinophilic asthma (SEA). This subgroup analysis aimed to characterize patients and outcomes based on baseline blood eosinophil count (BEC) and/or fractional exhaled nitric oxide (FeNO) levels.

Methods: In this analysis of the ORBE II retrospective study, SEA patients receiving benralizumab were categorized into subgroups based on individual or combined BEC/FeNO levels, according to the following thresholds: high BEC (hiBEC): ≥300 cells/μL; low BEC (loBEC): <300 cells/μL; high FeNO (hiFeNO): ≥50 ppb; low FeNO (loFeNO): <50 ppb.

Effect of Probiotics on C-Reactive Protein Levels in Schizophrenia: Evidence from a Systematic Review and Meta-Analysis.

Background: Inflammatory markers play a pivotal role in schizophrenia, as they provide insight into the neuroinflammatory processes occurring in the context of the disorder. Elevated levels of these markers, particularly C-reactive protein (CRP), can indicate an underlying immune system dysregulation, potentially influencing symptom severity and progression. Recognizing these markers has led to investigate the use of probiotics as an adjuvant to improve the treatment of schizophrenia.

Diagnostic Performance of Two Different Techniques to Quantify CMV-Specific Cell-Mediated Immunity in Intermediate-Risk Seropositive Kidney Transplant Recipients.

Background: Kidney transplant (KT) recipients at intermediate risk for cytomegalovirus (CMV) infection constitute a potential target for individualized prevention strategies informed by the CMV-specific cell-mediated immunity (CMV-CMI). The optimal method for the functional assessment of CMV-CMI in this group remains unclear.

Methods: We included 74 CMV-seropositive KT recipients that did not receive T-cell-depleting induction and were managed by preemptive therapy.

Efficacy outcomes of CDK4/6 inhibitors in combination with endocrine therapy treatment in hormone receptor-positive/HER2-negative advanced breast cancer according to PAM50 intrinsic subtype: Primary results of SOLTI-1801 CDK-PREDICT study.
