HBV shows different levels of adaptation to HLA class I-associated selection pressure correlating with markers of replication.

Background & Aims: Immune responses by CD8 T cells are essential for control of HBV replication. Although selection of escape mutations in CD8 T-cell epitopes has been previously described in HBV infection, its overall influence on HBV sequence diversity and correlation with markers of HBV replication remain unclear.

Methods: Whole-genome sequencing was applied to HBV isolates from 532 patients with chronic HBV infection and high-resolution HLA class I genotyping.

Development of a prognostic model to predict 90-day mortality in hospitalised cancer patients (PROMISE tool): a prospective observational study.

Background: Prognostic factors for ambulatory oncology patients have been described, including Eastern Cooperative Oncology Group (ECOG), tumor stage and malnutrition. However, there is no firm evidence on which variables best predict mortality in hospitalized patients receiving active systemic treatment. Our main goal was to develop a predictive model for 90-day mortality upon admission.

Circulating tumor DNA status and dynamics predict recurrence in patients with resected extrahepatic cholangiocarcinoma.

Background & Aims: Surgery is the only curative therapeutic option for resectable extrahepatic cholangiocarcinoma, but recurrence is common, and prognosis is poor. There is an unmet clinical need for improved decision-making regarding adjuvant chemotherapy (ACT). Herein, we evaluated the usefulness of monitoring longitudinal circulating tumor DNA (ctDNA) for molecular residual disease (MRD) in patients from the STAMP trial, which compares the efficacy of adjuvant capecitabine (CAP) vs.

PARP inhibitors in gliomas: Mechanisms of action, current trends and future perspectives.

Gliomas are the most common primary malignant brain tumours in adults. Despite decades of research into novel therapeutic approaches, the prognosis remains poor. PARP1-2 are critical for DNA repair, cell survival and genomic stability and PARP inhibition (PARPi) may be a promising therapeutic approach for gliomas.

Pembrolizumab 400 mg every 6 weeks as first-line therapy for advanced melanoma (KEYNOTE-555): Results from cohort B of an open-label, phase 1 study.

Intravenous pembrolizumab 400 mg every 6 weeks was approved across tumor types based on pharmacokinetic modeling, which showed exposures consistent with previous standard dosing of 200 mg or 2 mg/kg every 3 weeks, and early results of cohort B of the phase 1 KEYNOTE-555 study. Results after ≥1 year of potential follow-up for all patients in cohort B of KEYNOTE-555 are presented. Patients aged ≥18 years with previously untreated stage III/IV melanoma received pembrolizumab 400 mg every 6 weeks for ≤18 cycles.

Length of hospital and intensive care unit stay in patients with invasive candidiasis and/or candidemia treated with rezafungin: a pooled analysis of two randomised controlled trials.

Background: Invasive candidiasis/candidemia (IC/C) is associated with a substantial health economic burden driven primarily by prolonged hospital stay. The once-weekly IV echinocandin, rezafungin acetate, has demonstrated non-inferiority to caspofungin in the treatment of IC/C. This paper reports a post hoc pooled exploratory analysis of length of stay (LoS) for hospital and intensive care unit (ICU) stays in two previously published clinical trials (ReSTORE [NCT03667690] and STRIVE [NCT02734862], that compared rezafungin with daily IV caspofungin (stable patients in the caspofungin group who met relevant criteria could step down to fluconazole after 3 days or more).

Benchmark of screening markers for KEAP1/NFE2L2 mutations and joint analysis with the K1N2-score.

Our recently published K1N2-score robustly predicts KEAP1/NFE2L2-mutations and pathway activation status, while its accessibility might be limited. We tested if the RNA expression data of six pathway-related genes and NQO1-IHC might be a reliable alternative using 348 KEAP1/NFE2L2 mutation-enriched NSCLC. While TXNRD1 RNA testing was the best-performing single-gene test, the combination of single-gene screening and validation with the K1N2-score achieved the highest performance when predicting mutation status or pathway activation.

Improving precision of vaccine efficacy evaluation using immune correlate data in time-to-event models.

Understanding potential differences in vaccine-induced protection between demographic subgroups is key for vaccine development. Vaccine efficacy evaluation across these subgroups in phase 2b or 3 clinical trials presents challenges due to lack of precision: such trials are typically designed to demonstrate overall efficacy rather than to differentiate its value between subgroups. This study proposes a method for estimating vaccine efficacy using immunogenicity (instead of vaccination status) as a predictor in time-to-event models.

Carbapenem-resistant Enterobacterales in solid organ transplant recipients.

Carbapenem-resistant Enterobacterales (CRE) are an important threat to the health of solid organ transplant recipients (SOTr); data comparing outcomes of SOTr with CRE to non-SOTr with CRE are lacking. A matched cohort study was performed within 2 prospective, multicenter, cohort studies (Consortium on Resistance Against Carbapenems in Klebsiella and other Enterobacterales and Consortium on Resistance Against Carbapenems in Klebsiella and other Enterobacterales 2). The epidemiology, desirability of outcome rankings outcomes, and mortality of SOTr and non-SOTr hospitalized in the United States (December 2011-August 2017) with clinical isolates with Centers for Disease Control and Prevention-defined CRE were compared.

Durvalumab Versus Chemotherapy as First-line Treatment for Metastatic NSCLC With Tumor PD-L1 Expression of 25% or Higher: Results From the Randomized Phase 3 PEARL Study.

Introduction: PEARL (NCT03003962) is an open-label, phase 3 study comparing first-line durvalumab monotherapy with chemotherapy in patients with metastatic NSCLC (mNSCLC [EGFR/ALK wild type]) with programmed cell death ligand 1 (PD-L1) tumor cell (TC) membrane expression status of 25% or higher. We report the final analysis of PEARL.

Methods: Adults (N = 669) with previously untreated stage IV mNSCLC were randomized (1:1) to durvalumab 20 mg/kg every four weeks or chemotherapy every three weeks for four to six cycles.

Cardiovascular Risk Factors and Genetic Risk in Transthyretin V142I Carriers.

Background: Nearly 3% to 4% of Black individuals in the United States carry the transthyretin V142I variant, which increases their risk of heart failure. However, the role of cardiovascular (CV) risk factors (RFs) in influencing the risk of clinical outcomes among V142I variant carriers is unknown.

Objectives: This study aimed to assess the impact of CV RFs on the risk of heart failure in V142I carriers.

Smart Cancer-Targeting and Super-Sensitive Sensing of Eu/Tb-Induced Hyaluronan Characteristic Nano-Micelles with Effective Drug Loading and Release.

To avoid the critical problems of effective drugs not being carried to their targeted cancers and their quantity and location not being sensed in situ, this work presents a completely new innovative strategy to achieve both smart cancer targeting (SCT) and super-sensitive sensing (SSS), where one drug carrier works for effective drug loading and release. Herein, malignant melanoma treatment is used as an example of reliable detection and effective therapy. We report two characteristic dumbbell-like nano-micelles and spherical-like nano-micelles of hyaluronan induced by the Eu/Tb complexes for effective drug loading and release, respectively.
