Preclinical Mouse Intraductal Model (MIND) to Study Metastatic Dormancy in Estrogen Receptor-Positive Breast Cancer.

Here, we describe a clinically relevant xenograft model of hormone receptor-positive breast cancer that maintains estrogen receptor (ER) status without the need for exogenous supplementation of hormones. The naturally low 17-β-estradiol levels in host mice recapitulate levels seen in post-menopausal women. By introducing breast cancer cells directly into their "natural" microenvironment of the milk ducts, these cells maintain hormone receptor status, model the clinical progression of the disease, and develop ER metastatic lesions or dormant micrometastatic lesions in the case of ER BC.

Rapid autopsies to enhance metastatic research: the UPTIDER post-mortem tissue donation program.

Research on metastatic cancer has been hampered by limited sample availability. Here we present the breast cancer post-mortem tissue donation program UPTIDER and show how it enabled sampling of a median of 31 (range: 5-90) metastases and 5-8 liquids per patient from its first 20 patients. In a dedicated experiment, we show the mild impact of increasing time after death on RNA quality, transcriptional profiles and immunohistochemical staining in tumor tissue samples.

A New Wrist-Worn Tool Supporting the Diagnosis of Parkinsonian Motor Syndromes.

To date, clinical expert opinion is the gold standard diagnostic technique for Parkinson's disease (PD), and continuous monitoring is a promising candidate marker. This study assesses the feasibility and performance of a new wearable tool for supporting the diagnosis of Parkinsonian motor syndromes. The proposed method is based on the use of a wrist-worn measuring system, the execution of a passive, continuous recording session, and a computation of two digital biomarkers (i.

Clinical assessment of a new wearable tool for continuous and objective recording of motor fluctuations and ON/OFF states in patients with Parkinson's disease.

Clinical rating scales typically includes subjective evaluations, and their time-limited duration may fail to capture daily fluctuations in motor symptoms resulting from Parkinson's disease (PD). Recently, a new tool (i.e.

Understanding triage assessment of acuity by emergency nurses at initial adult patient presentation: A qualitative systematic review.

Background: Nurses make complex triage decisions within emergency departments, which significantly affect patient outcomes. Understanding how nurses make these decisions and why they deviate from triage algorithms facilitates interventions that work with their decision-making processes, increasing acceptability and effectiveness.

Aims: This qualitative systematic review aimed to understand decision-making processes emergency nurses use to make acuity decisions during triage assessment at initial patient presentation.
