Combined pyrotinib and fulvestrant for hormone receptor-positive and HER2-positive metastatic breast cancer: A multicenter, single-arm, phase II trial.

This multicenter, single-arm, phase II clinical trial (NCT04034589) evaluated the efficacy and safety of pyrotinib combined with fulvestrant in patients with HR-positive/HER2-positive metastatic breast cancer who had experienced trastuzumab treatment failure. A total of 46 patients were enrolled, receiving pyrotinib orally once daily and fulvestrant intramuscularly on days 1 and 15 of cycle 1, followed by monthly doses on day 1. The primary endpoint was progression-free survival (PFS), while secondary endpoints included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety.

The involvement of the dysfunctional insulin receptor signaling system in long COVID patients with diabetes and chronic pain and its implications for the clinical management using taVNS.

In clinical terms, chronic pain is the most prevalent sequela resulting from COVID-19, which is induced by the novel coronavirus (SARS-CoV-2), while type 2 diabetes mellitus (T2D) is the most common comorbidity. This triangular relationship can be attributed to the dysfunction of the insulin receptor signaling system (IRSS) in both central and peripheral systems. Patients with T2D are essentially more susceptible to SARS-CoV-2 infection due to the widespread expression of angiotensin converting enzyme 2 (ACE2) in their pancreatic beta cells, which serves as the cellular port for the SARS-CoV-2 to infect and enter the cell.

Effect of scalp nerve block on postcraniotomy analgesia in children: a randomized, controlled trial.

Objective: Effective postoperative pain management is critical for pediatric craniotomies. Scalp nerve block (SNB) interventions present a potential solution, yet their comparative benefits in preoperative and postoperative settings remain unclear. This study investigated the analgesic effects of SNB in pediatric craniotomy patients by comparing preoperative versus postoperative administration.

Dabrafenib Inhibits Egr-1-Mediated Adhesion of Thyroid Cancer Cells to Pulmonary Microvascular Endothelium.

Cell-cell adhesion between thyroid tumor cells and pulmonary endothelial cells plays a critical role in the development of lung metastases from primary thyroid cancer. Dabrafenib, a selective inhibitor for B-RAF kinase, has been approved for cancer treatment. However, its effects on pulmonary metastases originating from primary thyroid cancer remain unclear.

Purpose: This study aimed to investigate the accuracy of three fixation methods in patients with left breast cancer receiving whole breast radiotherapy: conventional breast bracket (BB), breast bracket combined with deep inspiration breath holding (DIBH), and cervical-thoracic integrated bracket (CTIB) combined with DIBH.

Methods: From January 2023 to September 2023, 84 patients who underwent left breast cancer radiotherapy with supraclavicular radiation after conservative surgery were included in this study, of which 25 patients were fixed by conventional BB, 34 patients by BB & DIBH, and 25 patients by CTIB & DIBH. Image registration was conducted around the treatment area, using the sternoclavicular joint and acromioclavicular joint as landmarks.

Tislelizumab plus chemotherapy as first-line treatment of locally advanced or metastatic nonsquamous non-small-cell lung cancer (final analysis of RATIONALE-304: a randomized phase III trial).

Background: The purpose of this study was to report an updated, final analysis with longer follow-up for the open-label phase III RATIONALE-304 study of first-line tislelizumab plus chemotherapy versus chemotherapy alone for advanced nonsquamous non-small-cell lung cancer (nsq-NSCLC).

Materials And Methods: Patients with histologically confirmed stage IIIB/IV nsq-NSCLC were randomized (2 : 1) to 4-6 cycles of tislelizumab plus platinum-based chemotherapy and pemetrexed every 3 weeks, followed by maintenance tislelizumab and pemetrexed, or platinum-based chemotherapy and pemetrexed alone every 3 weeks followed by maintenance pemetrexed. The primary endpoint was independent review committee (IRC)-assessed progression-free survival (PFS).

Development and validation of the NCC-BC-A scale to assess patient-reported outcomes for breast cancer patients in China.

Background: The commonly used international patient-reported outcome scales for breast cancer were developed before the advent of multiple targeted therapies and immunotherapies, rendering them potentially insufficient for current clinical practices. Therefore, it is necessary to develop a specific patient-reported outcome scale tailored for breast cancer patients in China to optimize the management model for these patients.

Methods: A comprehensive literature search was performed in the PubMed, Embase, Wanfang, and CNKI databases to extract dimensions and items for a potential patient-reported outcome scale.

Copper Nanoparticles Green-Formulated by Curcuma longa Extract Induce Apoptosis via P53 and STAT3 Signaling Pathways in Bladder Carcinoma Cell.

The study outlines the production of new copper nanoparticles infused with Curcuma longa extract to trigger apoptosis through P53 and signal transducer and activator of transcription 3 (STAT3) signaling pathways in bladder carcinoma cells. The structural characteristics of the nanoparticles that were synthesized were analyzed through various sophisticated methods such as transmission electron microscopy (TEM), field emission-scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FT-IR). During the antioxidant evaluation, the IC values for copper nanoparticles and butylated hydroxytoluene (BHT) against 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals were found to be 116 µg/mL and 31 µg/mL, respectively.
