Imaging manifestations of cervical aggressive fibromatosis: a case report and literature review.

Cervical aggressive fibromatosis is a rare intermediate tumor characterized by invasive growth. Aggressive fibromatosis (AF), also referred to as desmoid-type fibrosarcoma or grade I fibrosarcoma, is a clonal proliferative lesion of fibroblasts located in deep soft tissues. While many cases have been reported, there are relatively few involving aggressive fibromatosis in the anterior inferior margin muscle space of the neck trapezius muscle.

A causal relationship between bone mineral density and breast cancer risk: a mendelian randomization study based on east Asian population.

Background: Breast cancer (BC) poses significant burdens on women globally. While past research suggests a potential link between bone mineral density (BMD) and BC risk, findings remain inconsistent. Our study aims to elucidate the causal relationship between BMD and BC in East Asians using bidirectional Mendelian randomization (MR).

Effect of perioperative chemotherapy on resection of isolated pulmonary metastases from colorectal cancer: A single center experience.

Background: Numerous studies have assessed surgical resection as a standard treatment option for patients with colorectal cancer (CRC) and resectable pulmonary metastases (PM). However, the role of perioperative chemotherapy after complete resection of isolated PM from patients with CRC patients remains controversial. We hypothesize that perioperative chemotherapy does not provide significant survival benefits for patients undergoing resection of PM from CRC.

Highlighting immune features of the tumor ecosystem and prognostic value of Tfh and Th17 cell infiltration in head and neck squamous cell carcinoma by single-cell RNA-seq.

Background: Head and neck squamous cell carcinoma (HNSCC) typically present with a complex anatomical distribution, often accompanied by insidious symptoms. This combination contributes to its high incidence and poor prognosis. It is now understood that the immune features of cellular components within the tumor ecosystem and their complex interactions are critical factors influencing both tumor progression and the effective immune response.

Potential of Progressive and Disruptive Innovation-Driven Cost Reductions of Green Hydrogen Production.

Green hydrogen from water electrolysis is a key driver for energy and industrial decarbonization. The prediction of the future green hydrogen cost reduction is required for investment and policy-making purposes but is complicated due to a lack of data, incomplete accounting for costs, and difficulty justifying trend predictions. A new AI-assisted data-driven prediction model is developed for an in-depth analysis of the current and future levelized costs of green hydrogen, driven by both progressive and disruptive innovations.

YY1 mediated DCUN1D5 transcriptional activation promotes triple-negative breast cancer progression by targeting FN1/PI3K/AKT pathway.

Triple-negative breast cancer (TNBC) is more aggressive and has a higher metastasis rate compared with other subtypes of breast cancer. Due to the lack of drug-targetable receptors, chemotherapy is now the only available systemic treatment for TNBC. However, some patients might still develop drug resistance and have poor prognosis.

Additional prognostic value of polymorphisms within the 3'-untranslated region of programmed cell death pathway genes in early-stage breast cancer.

Introduction: The programmed cell death (PCD) pathway plays an important role in restricting cancer cell survival and proliferation. However, limited studies have investigated the association between genetic variants in the 3'-untranslated region of the PCD pathway genes and breast cancer outcomes.

Methods: In this study, we genotyped 28 potentially functional single nucleotide polymorphisms (SNPs) in 23 PCD pathway genes in 1,177 patients with early-stage breast cancer (EBC) from a Han Chinese population.

Unified cross-modality integration and analysis of T cell receptors and T cell transcriptomes by low-resource-aware representation learning.

Single-cell RNA sequencing (scRNA-seq) and T cell receptor sequencing (TCR-seq) are pivotal for investigating T cell heterogeneity. Integrating these modalities, which is expected to uncover profound insights in immunology that might otherwise go unnoticed with a single modality, faces computational challenges due to the low-resource characteristics of the multimodal data. Herein, we present UniTCR, a novel low-resource-aware multimodal representation learning framework designed for the unified cross-modality integration, enabling comprehensive T cell analysis.

Prognostic Implication of Platelet Reactivity According to Procedural Complexity After PCI: Subanalysis of PTRG-DES Consortium.

Background: Complex percutaneous coronary intervention (C-PCI) and high platelet reactivity (HPR) have been proposed as representative risk factors for the high ischemic phenotype. Uncertainty remains regarding the relative prognostic importance of these factors.

Objectives: This study aimed to investigate the prognostic implication of HPR according to procedural complexity.

Personalized tumor combination therapy optimization using the single-cell transcriptome.

Background: The precise characterization of individual tumors and immune microenvironments using transcriptome sequencing has provided a great opportunity for successful personalized cancer treatment. However, the cancer treatment response is often characterized by in vitro assays or bulk transcriptomes that neglect the heterogeneity of malignant tumors in vivo and the immune microenvironment, motivating the need to use single-cell transcriptomes for personalized cancer treatment.

Methods: Here, we present comboSC, a computational proof-of-concept study to explore the feasibility of personalized cancer combination therapy optimization using single-cell transcriptomes.

Clinical characteristics of liver injury induced by immune checkpoint inhibitors in patients with advanced biliary tract carcinoma.

Immune-related liver injuries are closely associated with the liver's fundamental state. Patients with advanced biliary tract carcinoma (BTC) have poor liver function. We evaluated the clinical data of immune-related liver injury in patients with advanced BTC and gastric cancer (GC) during immune checkpoint inhibitor (ICI) treatment between February 2019 and July 2022 at Peking University First Hospital.

Next-generation magnesium-ion batteries: The quasi-solid-state approach to multivalent metal ion storage.

Mg-ion batteries offer a safe, low-cost, and high-energy density alternative to current Li-ion batteries. However, nonaqueous Mg-ion batteries struggle with poor ionic conductivity, while aqueous batteries face a narrow electrochemical window. Our group previously developed a water-in-salt battery with an operating voltage above 2 V yet still lower than its nonaqueous counterpart because of the dominance of proton over Mg-ion insertion in the cathode.

Purpose: The study aimed to investigate the clinical characteristics, prognostic factors, survival times, and therapy outcomes of brain metastases (BM) from colorectal cancer (CRC).

Methods: The clinical characteristics of 25 patients with BM from CRC were retrospectively analyzed. The time of the occurrence of BM after diagnosis of CRC was recorded.

Clinical Outcomes of Calcium-Channel Blocker vs Beta-Blocker: From the Korean Acute Myocardial Infarction Registry.

Background: Although current guidelines recommend beta-blockers (BBs) after acute myocardial infarction (AMI), the role of calcium-channel blockers (CCBs) has not been well investigated, especially nondihydropyridine.

Objectives: This study aimed to compare the effects of CCBs on cardiovascular outcomes compared with BBs in AMI because patients from East Asia have a higher incidence of a vasospastic angina component compared with Western countries.

Methods: Among 15,628 patients enrolled in the KAMIR-V (Korean Acute Myocardial Infarction Registry-V), we evaluated 10,650 in-hospital survivors who were treated with either CCBs or BBs.

Statin therapy reduces dementia risk in atrial fibrillation patients receiving oral anticoagulants.

Aims: Atrial fibrillation (AF) is linked to an increased risk of dementia, even in stroke-free patients. The impact of statin therapy on dementia risk is unclear in AF patients receiving oral anticoagulant (OAC) (vitamin K antagonist and direct-acting OAC). We sought to investigate the impact of statin therapy on dementia risk in AF patients receiving OAC.

High leukocyte mitochondrial DNA copy number contributes to poor prognosis in breast cancer patients.

Background: Compelling evidence has indicated a significant association between leukocyte mitochondrial DNA copy number (mtDNAcn) and prognosis of several malignancies in a cancer-specific manner. However, whether leukocyte mtDNAcn can predict the clinical outcome of breast cancer (BC) patients has not been well investigated.

Methods: The mtDNA copy number of peripheral blood leukocytes from 661 BC patients was measured using a Multiplex AccuCopy™Kit based on a multiplex fluorescence competitive PCR principle.

PD-1/PD-L1 Inhibitor Plus Chemotherapy Versus PD-1/PD-L1 Inhibitor in Microsatellite Instability Gastrointestinal Cancers: A Multicenter Retrospective Study.

Purpose: To investigate the efficacy of PD-1/PD-L1 inhibitors plus chemotherapy versus anti-PD-1/PD-L1 monotherapy in advanced microsatellite instability (MSI)/mismatch repair-deficient (dMMR) gastrointestinal cancers.

Methods: We retrospectively recruited patients with MSI/dMMR gastrointestinal cancer who received anti-PD-1/PD-L1 with or without chemotherapy and compared objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) of PD-1/PD-L1 inhibitor plus chemotherapy (chemo-anti-PD-1/PD-L1 group) and PD-1/PD-L1 inhibitor alone (anti-PD-1/PD-L1 group). Propensity score-based overlap weighting analysis was conducted to adjust the baseline covariable imbalance.
