Article Synopsis
  • The study aimed to predict the muscular invasion status of bladder urothelial carcinoma using advanced diffusion-weighted imaging techniques and compare the effectiveness of these techniques with the established VI-RADS system.
  • Patients with confirmed UCB underwent preoperative MRI, and several quantitative imaging parameters were analyzed to distinguish between non-muscle invasive and muscle-invasive cases.
  • The results showed that specific diffusion metrics (Axial diffusivity and Mean diffusivity) were strong predictors for muscle invasion, leading to a new MRI model that outperformed the VI-RADS system in diagnostic accuracy.

Rationale And Objectives: To evaluate the potential of Synthetic Magnetic Resonance Imaging (SynMRI) in identifying muscular invasion in bladder cancer (BCa), and explore whether there is additional value in combination with the Vesical Imaging-Reporting and Data System (VI-RADS).

Methods: In this prospective single-center study, pathologically-confirmed BCa were enrolled between May 2023 and November 2023. All participants underwent preoperative multiparametric MRI, including T1/T2 weighted, SynMRI and diffusion-weighted imaging.

Objective: Our objective is to assess the oncologic outcomes of observation, elective neck dissection (END), and elective neck irradiation (ENI) in the neck management of head and neck cutaneous squamous cell carcinoma (HNcSCC) with parotid metastasis (P+) and to evaluate the quality of life (QoL) of patients who received END or ENI.

Methods: Patients with P+ HNcSCC were retrospectively enrolled. The impact of observation, END, and ENI on regional control (RC) and overall survival (OS) was analyzed using Cox proportional hazards model with presentation via hazard ratio (HR) with a 95% confidence interval (CI).

To investigate the prognostic value of lymph node status in patients with cervical cancer (CC) patients who underwent neoadjuvant chemotherapy (NACT) and followed hysterectomy. Patients in two referral centers were retrospectively analyzed. The baseline tumor size and radiological lymph node status (LNr) were evaluated on pre-NACT MRI.

Disruptions in large-scale brain connectivity are hypothesized to contribute to psychiatric disorders, including schizophrenia, bipolar I disorder, and attention-deficit/hyperactivity disorder. However, high inter-individual variation among patients with psychiatric disorders hinders achievement of unified findings. To this end, we adopted a newly proposed method to resolve heterogeneity of differential structural covariance network in schizophrenia, bipolar I disorder, and attention-deficit/hyperactivity disorder.

Continuously recording the dynamic changes of circulating tumor cells (CTCs) is crucial for tumor metastasis. This paper creates a continuous magnetic separation microfluidic chip that enables rapid and continuous cell detection. The chip shows its potential to study tumor cell circulation in the blood, offering a new platform for studying the cellular mechanism of tumor metastasis.

Background: The development of nursing interns' fundamental competencies should be a top focus because they represent an essential reserve for nursing professionals. The objective of this study is to investigate the relationship between spiritual care-giving competency (SCG) and nursing core competencies (NCC) among Chinese nursing interns, adopting a competency-based education (CBE) perspective, additionally, the study aims to examine how emotional intelligence (EI) serves as a mediator in this relationship.

Methods: A nationwide online survey was completed by 1811 Chinese nursing interns at vocational colleges between June and July 2022 as part of a multi-site, cross-sectional, web-based study.

Article Synopsis
  • Liquid biopsy technology uses body fluid samples to analyze tumor markers, allowing for early cancer diagnosis and treatment evaluation in a minimally invasive manner.
  • The paper presents a novel 3D magnetic chip (3DMC-system) designed for in vivo detection and real-time monitoring of circulating tumor cells (CTCs) using specialized magnetic nanospheres for better accuracy.
  • This system not only improves the detection of CTCs at early tumor stages but also has the potential to integrate treatment options, offering a personalized medical approach for cancer patients.

Extracellular vesicles (EVs), acting as important mediators of intercellular communication, play an essential role in physiological processes, which have unique potential in the medical field. However, the heterogeneity of EVs limits their development for disease diagnosis and therapy, making the EV subpopulation analysis extremely valuable. In this article, a simple microfluidic approach was presented for the on-chip specific isolation and detection of two phenotypes of EVs (Annexin V EGFR EVs and Annexin V EGFR EVs) based on different biomolecule-modified magnetic nanospheres and a fluorescence labeling technique.

Among the numerous forms of cancer immunotherapy, cancer vaccines have attracted increasing attention because of their ability to elicit sustained antitumor immune responses and durable tumor regression. Here, a personalized gel-droplet monocyte vaccine (GEMA) derived from host blood was reported. A streamlined microfluidic vaccine production platform was designed to combine the separation of monocytes from host blood and the encapsulation of monocytes in an alginate gel droplet, which simplified the handling of the blood product and permitted the rapid preparation of vaccines.
