Effectiveness of Co-Testing in Cervical Cancer Screening Program in Macao SAR

引用

Health 2024年第8期16卷 763-769页

作者： Lamlam Chan Kamweng wong Centro Hospitalar Conde de So Janurio Macao SAR China

Background: Cervical cancer remains a significant public health concern in Macao SAR despite the implementation of a cervical cancer screening program and HPV vaccination. To improve early detection, Macao SAR introduced HPV DNA testing alongside cytology (co-testing) as the primary screening method in 2019. This study evaluates the effectiveness of co-testing in identifying cervical precancerous lesions (CIN2+) compared to cytology alone. Methods: We conducted a retrospective analysis of women aged 30 - 65 years who participated in the routine cervical cancer screening program in Macao SAR Primary Healthcare Centers from 2019 to 2022. Data from over 70,000 women were analyzed, comparing the detection rates of CIN2+ through co-testing and cytology alone. Women with abnormal cytology or positive HPV results were referred for colposcopy. Results: The introduction of co-testing led to a significant increase in the detection of CIN2+, particularly in women with atypical squamous cells of undetermined significance (ASCUS) or negative for intraepithelial lesion or malignancy (NILM) cytology results. Between 2019 and 2022, the percentage of women with ASCUS/NILM and any high-risk HPV (hrHPV) positive who were diagnosed with CIN2+ after colposcopy were 24%, 13%, 10% and 7.5% respectively. This highlights the ability of co-testing to identify high-risk individuals who would have been missed by cytology alone. Discussion: Our findings demonstrate the effectiveness of co-testing in improving the sensitivity of cervical cancer screening in Macao SAR. The inclusion of HPV DNA testing allows for better risk stratification of women with ASCUS/NILM cytology, leading to more targeted referrals for colposcopy and timely detection of precancerous lesions. The initial high positive rate in 2019 (24%) might be attributed to the small sample size and potentially reflects a backlog of undiagnosed cases prior to co-testing implementation. Conclusion: The implementation of co-testing in Mac

Quantum Realities and Observer-Dependent Universes: An Advanced Observer Model

引用

Journal of Quantum Information Science 2024年第3期14卷 69-121页

作者： Joseph Hon Cheung wong Department of Computing The Hong Kong Polytechnic University Hung Hom Kowloon Hong Kong China

This paper presents a novel observer model that integrates quantum mechanics, relativity, idealism, and the simulation hypothesis to explain the quantum nature of the universe. The model posits a central server transmitting multi-media frames to create observer-dependent realities. Key aspects include deriving frame rates, defining quantum reality, and establishing hierarchical observer structures. The model’s impact on quantum information theory and philosophical interpretations of reality are examined, with detailed discussions on information loss and recursive frame transmission in the appendices.

Monogenic features of urolithiasis: A comprehensive review

Objective: Urolithiasis formation has been attributed to environmental and dietary factors. However, evidence is accumulating that genetic background can contribute to urolithiasis formation. Advancements in the identification of monogenic causes using high-throughput sequencing technologies have shown that urolithiasis has a strong heritable ***: This review describes monogenic factors implicated in a genetic predisposition to urolithiasis. Peer-reviewed journals were evaluated by a PubMed search until July 2023 to summarize disorders associated with monogenic traits, and discuss clinical implications of identification of patients genetically susceptible to urolithiasis ***: Given that more than 80% of urolithiases cases are associated with calcium accumulation, studies have focused mainly on monogenetic contributors to hypercalciuric urolithiases, leading to the identification of receptors, channels, and transporters involved in the regulation of calcium renal tubular reabsorption. Nevertheless, available candidate genes and linkage methods have a low resolution for evaluation of the effects of genetic components versus those of environmental, dietary, and hormonal factors, and genotypes remain undetermined in the majority of urolithiasis ***: The pathophysiology underlying urolithiasis formation is complex and multifactorial, but evidence strongly suggests the existence of numerous monogenic causes of urolithiasis in humans.

Recent progress in circularly polarized multi-resonance thermally activated delayed fluorescence materials for organic light-emitting diodes

引用

Science China Chemistry 2024年

作者： He Jiang Dan Ai Jibiao Jin Zheng Xie Wai-Yeung wong Department of Applied Biology and Chemical Technology and Research Institute for Smart Energy The Hong Kong Polytechnic University School of Chemistry and Chemical Engineering University of Jinan The Hong Kong Polytechnic University Shenzhen Research Institute

Circularly polarized luminescence(CPL) is of importance to advance science and technology with significant potential applications in information storage, spintronics and optoelectronic devices. Integrating CPL and the emission mechanism of thermally activated delayed fluorescence(TADF) has attracted considerable attention, because of their 100% internal quantum efficiency in theory and easily modified molecular structures for tunable photo-electrical properties. However, the typical donor-acceptor(D-A) architecture of CP-TADF emitters generally induces a broad emission profile with inferior color purity due to their large structural relaxation under the processes of excitation and emission. Recently, CP-multi-resonance(MR)-TADF emitters that concurrently display CPL activity, narrowband emission and high efficiency are emerging as the most suitable candidates for the next-generation organic light-emitting diode(OLED) display. In this review, the progress of CP-MR-TADF materials is reviewed in terms of the molecular design strategy, the common relationship between the molecular structures and optoelectronic properties, and their OLEDs performance. Finally, the opportunities and challenges in this research topic are discussed.
