Cardiac surgery with valve replacement temporarily disrupts the hippocampal memory network.

Background: Systemic inflammation after heart valve replacement surgery commonly results in complications including cognitive impairment. This study was designed to investigate whether valvular heart disease itself and inflammation after valve replacement surgery affects cognition and the related functional connectivity (FC) of the hippocampal memory network.

Methods: Forty-three patients with valvular heart disease were screened for recruitment and assessed with cognition function tests, blood inflammatory cytokine measurements, and functional magnetic resonance imaging scans before surgery and on postoperative day 7 and 30.

A combined model of circulating tumor DNA methylated SHOX2/SCT/HOXA7 and clinical features facilitates the discrimination of malignant from benign pulmonary nodules.

Background: Despite the advancements in early lung cancer detection attributed to the widespread use of low-dose computed tomography (LDCT), this technology has also led to an increasing number of pulmonary nodules (PNs) of indeterminate significance being identified. Therefore, this study was aimed to develop a model that leverages plasma methylation biomarkers and clinical characteristics to distinguish between malignant and benign PNs.

Methods: In a training cohort of 210 patients with PNs, we evaluated plasma circulating tumor DNA (ctDNA) for the presence of three lung cancer-specific methylation markers: SHOX2, SCT, and HOXA7.

A "plug-and-display" nanoparticle based on attenuated outer membrane vesicles enhances the immunogenicity of protein antigens.

As natural nanoparticle, the bacterial outer membrane vesicles (OMV) hold great potential in protein vaccines because of its self-adjuvant properties and good biocompatibility. However, the inherent immunotoxicity seriously hampers the application of OMV as protein antigens delivery carrier. Here, an attenuated OMV was constructed by elimination of the flagella protein from its surface and removal of the phosphate group of LPS at position one via gene-editing strategy.

Lung ultrasound on first postoperative day predicts out-of-hospital pulmonary complications following video-assisted thoracic surgery: A prospective cohort study.

Background: The integration of enhanced recovery after surgery (ERAS) protocols into the peri-operative management of video-assisted thoracic surgery (VATS) has facilitated rapid patient recovery, enabling discharge within 48 h. However, postoperative pulmonary complications (PPCs) postdischarge pose significant concerns for patient welfare. Despite the established utility of lung ultrasound (LUS) in diagnosing the causes of dyspnoea, the effectiveness of quantitative LUS in predicting PPCs after VATS remains uncertain.

Patient-reported outcomes of rezvilutamide versus bicalutamide in combination with androgen deprivation therapy in high-volume metastatic hormone-sensitive prostate cancer patients (CHART): a randomized, phase 3 study.

The randomized phase 3 CHART trial (NCT03520478) revealed that rezvilutamide (REZ) plus androgen deprivation therapy (ADT) in high-volume, metastatic, hormone-sensitive prostate cancer (mHSPC) significantly enhanced radiographic progression-free and overall survival than bicalutamide (BIC)-ADT. Accordingly, we examined patient-reported outcomes (PROs) results, which were exploratory endpoints in the CHART trial. The patients were randomly allocated to receive REZ-ADT or BIC-ADT in a 1:1 ratio.

Purpose: To develop a novel risk model incorporating Ga-PSMA PET/CT parameters for prediction of perineural invasion (PNI) of prostate cancer (PCa).

Methods: The study retrospectively enrolled 192 PCa patients with preoperative multiparametric MRI, Ga-PSMA PET/CT and radical specimen. Imaging parameters were derived from both mpMRI and PET/CT images.

KBTBD8/RRP15 as a potential novel therapeutic target associates with lenvatinib-inhibited progression in hepatocellular carcinoma both in vitro and in vivo.

Introduction: We have previously demonstrated that RRP15 (Ribosomal RNA Processing 15 Homolog) was significantly elevated in hepatocellular carcinoma (HCC) and correlated directly with poor prognosis. RRP15 suppression curtails HCC progression through induction of cellular senescence and apoptosis. However, the impact of RRP15 on the precise therapeutic potential of lenvatinib has remained underexplored.

Construction of a preoperative emotional state and postoperative intra-abdominal pressure based prediction model for early enteral feeding intolerance in postoperative patients with gastric cancer.

Background: The incidence of enteral feeding intolerance (ENFI) in the early postoperative period is high in patients after gastric cancer resection due to the characteristics of surgical traumatic stress and changes in the physiological structure of the digestive tract, and the current evaluation of ENFI after gastric cancer resection mostly depends on the symptoms and complaints of patients after gastric cancer resection, which is lagging and subjective. Early accurate and objective prediction of the risk of early ENFI after gastric cancer resection is critical to guide clinical enteral nutrition practice.

Materials And Methods: This study included 470 patients who underwent radical gastric cancer surgery at the Division of Gastric Surgery of a tertiary hospital in Nanjing, Jiangsu Province, between November 2021 and October 2022.
