is one of the three most frequently mutated genes in age-related clonal hematopoiesis (CH), alongside and (. CH can progress to myeloid malignancies including chronic monomyelocytic leukemia (CMML) and is also strongly associated with inflammatory cardiovascular disease and all-cause mortality in humans. DNMT3A and TET2 regulate DNA methylation and demethylation pathways, respectively, and loss-of-function mutations in these genes reduce DNA methylation in heterochromatin, allowing derepression of silenced elements in heterochromatin.

Background: The deep inferior epigastric perforator (DIEP) flap is currently the gold standard for autologous breast reconstruction. In cases where the DIEP is contraindicated, the profunda artery perforator (PAP) flap is now the preferred second-line option in our institution. The PAP flap poses unique challenges to the reconstructive surgeon, especially in Asian women with low body mass index (BMI).

Cost Effectiveness of Exclusionary EGFR Testing for Taiwanese Patients Newly Diagnosed with Advanced Lung Adenocarcinoma.

Pharmacoeconomics

January 2025

Division of Pulmonology, Department of Internal Medicine, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, 138 Shengli Road, Tainan, 704, Taiwan.

Background And Objective: Approximately half of lung adenocarcinomas in East Asia harbor epidermal growth factor receptor (EGFR) mutations. EGFR testing followed by tissue-based next-generation sequencing (NGS), upfront tissue-based NGS, and complementary NGS approaches have emerged on the front line to guide personalized therapy. We study the cost effectiveness of exclusionary EGFR testing for Taiwanese patients newly diagnosed with advanced lung adenocarcinoma.

The correlation between LAG-3 expression and the efficacy of chemoimmunotherapy in advanced biliary tract cancer.

Cancer Immunol Immunother

January 2025

Division of Medical Oncology, Department of Oncology, Taipei Veterans General Hospital, No. 201, Sec. 2, Shipai Road, Beitou District, Taipei, 112201, Taiwan.

In our previous phase II T1219 trial for advanced biliary tract cancer (ABTC), the combination of nivolumab with modified gemcitabine and S-1 exhibited promising efficacy, while the programmed-death-ligand-1 (PD-L1) expression did not predict chemoimmunotherapy efficacy. Lymphocyte-activation-gene-3 (LAG-3), a negative immune checkpoint, is frequently co-expressed with PD-L1. This study assessed the predictive value of LAG-3 expression in ABTC patients who received chemoimmunotherapy.

Lung

January 2025

Department of Internal Medicine, National Taiwan University Hospital, No.7, Chung Shan S. Rd., Zhongzheng District, Taipei City, 100225, Taiwan.

Purpose: Electronic noses (eNose) and gas chromatography mass spectrometry (GC-MS) are two important breath analysis approaches for differentiating between respiratory diseases. We evaluated the performance of a novel electronic nose for different respiratory diseases, and exhaled breath samples from patients were analyzed by GC-MS.

Materials And Methods: Patients with lung cancer, pneumonia, structural lung diseases, and healthy controls were recruited (May 2019-July 2022).

Background: Continuous speech analysis is considered as an efficient and convenient approach for early detection of Alzheimer's Disease (AD). However, the traditional approach generally requires human transcribers to transcribe audio data accurately. This study applied automatic speech recognition (ASR) in conjunction with natural language processing (NLP) techniques to automatically extract linguistic features from Chinese speech data.

Alzheimers Dement

December 2024

Department of Bioengineering, University of California, Los Angeles, CA, USA, Los Angeles, CA, USA.

Background: Alzheimer's disease (AD) is characterized by cognitive decline and increased seizure susceptibility due to brain damage and neural disruptions. This study examines the relationship between cognitive deterioration and seizure pathology in hAPP-J20 transgenic Alzheimer's mice, a model known for amyloid plaque deposition and heightened seizure activity.

Method: We observed hAPP-J20 mice aged 8 to 28 weeks using long-term wireless telemetry to assess hippocampal local field potential, sampled at 2 kHz.

Alzheimers Dement

December 2024

Academia Sinica, Taipei, Taiwan.

Background: There is a strong genetic component to Alzheimer's disease (AD), as evidenced in genome-wide association studies (GWASs) that have identified new variants associated with the disease. This is particularly true for the apolipoprotein E (APOE) gene and its neighboring genes on chromosome 19q13.3.

Background: It has been found that speech analysis is a sensitive method for early Alzheimer's disease (AD) detection. Among the various linguistic features, silent pause has emerged as a fair indicator, exhibiting higher prevalence in individuals with AD compared to general population. This study aimed to further examine the relationship between long pause ratio (LPR) in speech and traditional markers of disease progression, like biomarkers, neuroimaging features and neuropsychological tests.

Background: Gait performance has been found to be an effective method for screening cognitive impairment in elderly. Nevertheless, the efficacy of utilizing gait speed as a marker for monitoring cognitive changes remains incompletely substantiated.

Method: From 2021 to 2023, we recruited 104 participants from the memory clinic of Cardinal Tien Hospital in Taipei, Taiwan.

Background: High-level median or ulnar nerve injuries and repairs typically result in suboptimal re-innervation of distal muscles. Functioning Free Muscle Transplantation (FFMT) is increasingly recognized as an effective method to restore function in chronic muscle denervation cases. This study investigates the efficacy of using an additional FFMT, neurotized by lateral sprouting axons from a repaired high-level mixed nerve in the upper limb, to enhance distal hand function.

Objectives: The primary repair of the anterior cruciate ligament (ACL) has re-emerged as a treatment for acute ruptures. While numerous studies have investigated rehabilitation after ACL reconstruction, few have focused on primary repair. We aimed to describe the rehabilitation protocols for primary ACL repair, and to identify knowledge gaps and differences between primary ACL repair and reconstruction.

Acute myocardial infarction (AMI) represents a critical health challenge characterized by a significant reduction in blood flow to the heart, leading to high rates of mortality and morbidity. Cardiac troponins, specifically cardiac troponin I and cardiac troponin T, are essential proteins involved in cardiac muscle contraction and serve as vital biomarkers for the diagnosis of AMI. Aptasensors utilize synthetic aptamers or peptides with high affinity for specific biomarkers and offer a promising approach for integration into portable, user-friendly point-of-care (POC) applications.

Background: Stroke is a significant cause of morbidity and mortality worldwide, contributing substantially to the global burden of disease. In low- and middle-income countries, stroke tends to occur at younger ages, with infection being one of the notable contributing factors. Previous studies have explored the impact of nontyphoidal Salmonella (NTS) on vascular and blood-related diseases, with animal experiments confirming related mechanisms.

Circulating CD3CD8 cell levels were lower in breast cancer patients, elevated posttreatment, and subsequently declining upon recurrence. Elevated plasma chemokine (C-C motif) ligand 2 (CCL2) levels distinguished patients with breast cancer from healthy controls. In summary, circulating CD3CD8 CTL and plasma CCL2 levels emerged as promising dual-purpose biomarkers and therapeutic targets in breast cancer management.

Hepatitis B virus (HBV) DNA integration into the host cell genome is reportedly a major cause of liver cancer, and a source of hepatitis B surface antigen (HBsAg). High HBsAg levels can alter immune responses which therefore contributes to the progression of HBV-related disease. However, to what extent integration leads to the persistent circulating HBsAg is unclear.

Compelling evidence has solidified the notion of early treatment intensification in managing patients with metastatic hormone-sensitive prostate cancer (mHSPC). Landmark trials have provided Level 1 evidence for the survival benefits achieved by combining multiple agents. The efficacy of combined therapy relies not only on how treatment is intensified but also on how it is de-escalated.
