To determine whether culture yield and time to positivity (TTP) differ between peripheral and central vascular catheter-derived blood cultures (BCx) in neonatal intensive care unit (NICU) patients evaluated for late-onset sepsis.

Single-centre, retrospective, observational study.

Level IV NICU.

The study included infants >72 hours old admitted to NICU in 2007-2019 with culture-confirmed bacteraemia. All episodes had simultaneous BCx drawn from a peripheral site and a vascular catheter ('catheter culture').

Dual-site culture yield and TTP.

Among 179 episodes of late-onset bacteraemia (among 167 infants) with concurrently drawn peripheral and catheter BCx, the majority (67%, 120 of 179) were positive from both sites, compared with 17% (30 of 179) with positive catheter cultures only and 16% (29 of 179) with positive peripheral cultures only. find more 66% (19 of 29) of episodes with only positive peripheral BCx grew coagulase-negative
, while 34% (10 of 29) were recognised bacterial pathogens. Among 120 While dual-site culture practices may be useful, clinicians should balance the gain in sensitivity of bacteraemia detection against additive contamination risk.
Oncogenic kinase fusions are targetable with approved and investigational therapies and can also mediate acquired resistance (AR) to targeted therapy. We aimed to understand the clinical validity of liquid biopsy comprehensive genomic profiling (CGP) to detect kinase fusions pan tumor.

CGP was performed on plasma and tissue samples during clinical care. All exons plus selected introns of 16 kinases involved in oncogenic fusions (
and
) were sequenced to capture fusions, including well-characterized and novel breakpoints. Plasma circulating tumor DNA (ctDNA) fraction was estimated to inform sensitivity.

Of 36,916 plasma cases, 32,492 (88%) had detectable ctDNA. Kinase fusions were detected in 1.8% of ctDNA-positive cases (571/32,492) and were most prevalent in patients with cholangiocarcinoma (4.2%), bladder cancer (3.6%), and non-small cell lung cancer (NSCLC) (3.1%). Of the 63 paired patient samples that had tissue and ctDNA specimens collected within 1 year and with estimated plasma ctDNA fraction > 1%, fusions were detected in 47/51 (92%) liquid specimens with a fusion in the tissue sample. In 32 patients with fusions detected in liquid but not in tissue, 21 (66%) had evidence of putative acquired resistance.

Targetable kinase fusions are identified in ctDNA across cancer types. In pairs with tissue-identified fusions, fusion detection in ctDNA is reliable with elevated ctDNA fraction. These data support the validity of CGP to enable ctDNA-based fusion detection for informing clinical care in advanced cancer.

This meeting, in October 2020, brought together a panel of regulators and academic experts in acute myeloid leukemia (AML) to discuss opportunities to maximize the success that has recently occurred in AML drug development. The panel discussed challenges and opportunities in clinical trial design and novel endpoints, and outlined key considerations for drug development to facilitate continued growth in the field.
In this study, we aimed to evaluate the efficacy and safety of pyrotinib, a pan-HER inhibitor, in
-amplified NSCLC patients.

In this prospective, multicenter, single-arm trial (ChiCTR1800020262), advanced NSCLC patients with
amplification, as determined by next-generation sequencing, were enrolled and administered pyrotinib orally at 400 mg per day. The primary endpoint was 6-month progression-free survival (PFS) rate. Other endpoints included objective response rate (ORR), disease control rate (DCR), PFS, overall survival (OS), and safety.

The enrolled cohort included twenty-seven patients with
amplification. The 6-month PFS rate was 51.9% (95% confidence interval [CI] 34.0%-69.3%). The median PFS was 6.3 months (95%CI 3.0-9.6 months), and median OS was 12.5 months (95%CI 8.2-16.8 months). Pyrotinib elicited a confirmed ORR of 22.2% (95%CI 10.6%-40.8%). Patients administered pyrotinib as first-line treatment achieved an mPFS of 12.4 months. Moreover, 30.8% of the patients who had progressed on epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) responded to pyrotinib. Patients with brain metastases had an ORR of 40%. Treatment-related adverse events (TRAEs) occurred in all patients (grade 3, 22.2%), but no grade 4 or higher TRAEs were documented. Diarrhea was the most frequent TRAE (all, 92.6%; grade 3, 7.4%). Loss of
amplification was detected upon disease progression.

The aim of the study was to determine safety, antitumor activity, and pharmacodynamic profile of mogamulizumab, an anti-CCR4 monoclonal antibody targeting effector regulatory T cells (eTregs) in combination with the checkpoint inhibitor nivolumab in patients with locally advanced or metastatic solid tumors.

This was a multicenter, dose-finding (phase I) and dose-expansion (phase II) study (NCT02705105) in patients with locally advanced or metastatic solid tumors. There were no dose-limiting toxicities in phase I with mogamulizumab 1 mg/kg every week for Cycle 1 followed by 1 mg/kg every 2 weeks plus nivolumab 240 mg every 2 weeks intravenously and cohort expansion occurred at this dose level.

All 114 patients treated with mogamulizumab 1 mg/kg plus nivolumab 240 mg in phases I (
= 4) and II (
= 110) were assessed for safety and efficacy. Mogamulizumab plus nivolumab showed acceptable safety and tolerability. Objective response rate was 10.5% (95% confidence interval [CI], 5.6 - 17.7%; 3 complete and 9 partial responses). Disease control rate was 36.8%. Median duration of response was 14.4 months. Median progression-free survival was 2.6 (95% CI, 2.3 ‑ 3.1) months and median overall survival was 9.5 (95% CI, 5.9-13.5) months.

Combination of mogamulizumab with nivolumab for treatment of patients with locally advanced or metastatic solid tumors did not result in enhanced efficacy. Tolerability of mogamulizumab 1 mg/kg plus nivolumab 240 mg was acceptable.

Patients presenting to EDs with chest pain of possible cardiac origin represent a substantial and challenging cohort to risk stratify. Scores such as HE-MACS (History and Electrocardiogram-only Manchester Acute Coronary Syndromes decision aid) and HEAR (History, ECG, Age, Risk factors) have been developed to stratify risk without the need for troponin testing. Validation of these scores remains limited.

We performed a post hoc analysis of the Limit of Detection and ECG discharge strategy randomised-controlled trial dataset (n=629; June 2018 to March 2019; 8 UK hospitals) to calculate HEAR and HE-MACS scores. A <4% risk of major adverse cardiac events (MACE) at 30 days using HE-MACS and a score of <2 calculated using HEAR defined 'very low risk' patients suitable for discharge. The primary outcome of MACE at 30 days was used to assess diagnostic accuracy.

MACE within 30 days occurred in 42/629 (7%) of the cohort. HE-MACS and HEAR scores identified 85/629 and 181/629 patients as 'very low risk', with MACE occurring in 0/85 and 1/181 patients, respectively. The sensitivities of each score for ruling out MACE were 100% (95% CI 91.6% to 100%) for HE-MACS and 97.6% (95% CI 87.7% to 99.9%) for HEAR. Presenting symptoms within these scores were poorly predictive, with only diaphoresis reaching statistical significance (OR 4.99 (2.33 to 10.67)). Conventional cardiovascular risk factors and clinician suspicion were related to the presence of MACE at 30 days.

HEAR and HE-MACS show potential as rule out tools for acute myocardial infarction without the need for troponin testing. However, prospective studies are required to further validate these scores.

However, we show here that membranous HER3 protein is commonly highly expressed in lethal PC, associating with reduced time to castration resistance (CR) and survival. Multiplex immunofluorescence indicated that the HER3 ligand NRG1 is detectable primarily in tumor-infiltrating myelomonocytic cells in human PC; this observation was confirmed using single cell RNA-seq of human PC biopsies and murine transgenic PC models. In CRPC patient-derived xenograft organoids (PDX-O) with high HER3 expression as well as mouse PC organoids, recombinant NRG1 enhanced proliferation and survival. Supernatant from murine bone marrow-derived macrophages and myeloid-derived suppressor cells promoted murine PC organoid growth in vitro, which could be reversed by a neutralizing anti-NRG1 antibody and ERBB inhibition. Targeting HER3, especially with the HER3 directed antibody-drug conjugate U3-1402, exhibited antitumor activity against HER3-expressing PC. Overall, this data indicates that HER3 is commonly overexpressed in lethal PC and can be activated by NRG1 secreted by myelomonocytic cells in the tumor microenvironment, supporting HER3-targeted therapeutic strategies for treating HER3-expressing advanced CRPC.Lung cancers (LC) are the leading cause of cancer-related mortality worldwide, and the majority of LC are non-small cell lung carcinoma (NSCLC). Overexpressed or activated EGFR has been associated with a poor prognosis in NSCLC. We previously identified a circular non-coding RNA, hsa_circ_0000190 (C190), as a negative prognostic biomarker of LC. Here we attempted to dissect the mechanistic function of C190 and test the potential of C190 as a therapeutic target in NSCLC. C190 was upregulated in both NSCLC clinical samples and cell lines. Activation of the EGFR pathway increased C190 expression through a MAPK/ERK-dependent mechanism. Transient and stable overexpression of C190 induced ERK1/2 phosphorylation, proliferation, and migration in vitro and xenograft tumor growth in vivo. RNA sequencing and Expression2Kinases (X2K) analysis indicated that kinases associated with cell cycle and global translation are involved in C190-activated networks, including CDKs and p70S6K, which were further validated by immunoblotting.
