Objective: This study introduces a novel tokenisation methodology, K-Tokeniser, to infuse clinical knowledge into language models for clinical text processing.

Methods: Technically, at initialisation stage, K-Tokeniser populates global representations of tokens based on semantic types of domain concepts (such as drugs or diseases) from either a domain ontology like Unified Medical Language System or the training data of the task related corpus. At training or inference stage, sentence level localised context will be utilised for choosing the optimal global token representation to realise the semantic-based tokenisation.

Transcatheter aortic valve implantation (TAVI) has been established as an effective treatment modality in patients with severe aortic stenosis (AS) and the uptake of TAVI is rapidly growing in the Asia-Pacific region. However, there exist a heterogeneity in the management of aortic stenosis and the use of TAVI among countries in the region. Reasons for these differences include anatomic variations, disparity in healthcare resources and infrastructure, and the lack of consensus on the optimal management of AS in the Asia-Pacific region.

The autonomous and active Long-Interspersed Element-1 (LINE-1, L1) and the non-autonomous Alu retrotransposon elements, contributing to 30% of the human genome, are the most abundant repeated sequences. With more than 90% of their sequences being methylated in normal cells, these elements undeniably contribute to the global DNA methylation level and constitute a major part of circulating-cell-free DNA (cfDNA). So far, the hypomethylation status of LINE-1 and Alu in cellular and extracellular DNA has long been considered a prevailing hallmark of ageing-related diseases and cancer.

The ribosomal genes (rDNA genes) encode 47S rRNA which accounts for up to 80% of all cellular RNA. At any given time, no more than 50% of rDNA genes are actively transcribed, and the other half is silent by forming heterochromatin structures through DNA methylation. In cancer cells, upregulation of ribosome biogenesis has been recognized as a hallmark feature, thus, the reduced methylation of rDNA promoter has been thought to support conformational changes of chromatin accessibility and the subsequent increase in rDNA transcription.

Article Synopsis
  • The COVID-19 pandemic led to significant treatment delays for patients needing transcatheter aortic valve replacement (TAVR), with a marked decrease in procedure volumes during the first two waves of the pandemic.
  • The study analyzed TAVR case data from 130 centers in 61 countries, finding a 15% drop in cases during the first wave and 7% in the second, particularly affecting regions like Africa, Central-South America, and Asia.
  • Factors such as hospital type (private vs public), urban vs rural location, low procedure volumes, a country's socioeconomic status, and stringent public health measures contributed to these reductions, highlighting the need for improved public health policies for future health crises.

The unique characteristics of patients with chronic coronary syndrome (CCS) in the Asia-Pacific region, heterogeneous approaches because of differences in accesses and resources and low number of patients from the Asia-Pacific region in pivotal studies, mean that international guidelines cannot be routinely applied to these populations. The Asian Pacific Society of Cardiology developed these consensus recommendations to summarise current evidence on the management of CCS and provide recommendations to assist clinicians treat patients from the region. The consensus recommendations were developed by an expert consensus panel who reviewed and appraised the available literature, with focus on data from patients in Asia-Pacific.

KRAS, NRAS, and BRAF are potential tumor-driven genes that are involved in the RAS/RAF/MAPK signaling pathway. RAS/RAF mutations importantly contribute to colorectal tumorigenesis since they remain the activated status of downstream pathways without regulation of the upstream EGFR signal. However, it has not been unclear how epigenetic alterations involved in colorectal tumorigenesis mediated by KRAS, NRAS, or BRAF mutations.

The Asia Renal Denervation Consortium consensus conference of Asian physicians actively performing renal denervation (RDN) was recently convened to share up-to-date information and regional perspectives, with the goal of consensus on RDN in Asia. First- and second-generation trials of RDN have demonstrated the efficacy and safety of this treatment modality for lowering blood pressure in patients with resistant hypertension. Considering the ethnic differences of the hypertension profile and demographics of cardiovascular disease demonstrated in the SYMPLICITY HTN (Renal Denervation in Patients With Uncontrolled Hypertension)-Japan study and Global SYMPLICITY registry data from Korea and Taiwan, RDN might be an effective hypertension management strategy in Asia.
