Health Technology Assessment in China's Health Care Sector: Development and Applications.

China's health system is facing severe challenges from social transition and the double burden of population aging and non-communicable diseases. Addressing the tension between the public's increasing demand for health services and the limited availability of medical resources has become a critical issue for health care policymakers and medical insurance fund administrators. In promoting its medical insurance system reform, China is actively developing health technology assessment (HTA) with principles and applications adapted to the Chinese context.

Economic Evaluation of COVID-19 Immunization Strategies: A Systematic Review and Narrative Synthesis.

Objectives: This study aimed to systematically assess global economic evaluation studies on COVID-19 vaccination, offer valuable insights for future economic evaluations, and assist policymakers in making evidence-based decisions regarding the implementation of COVID-19 vaccination.

Methods: Searches were performed from January 2020 to September 2023 across seven English databases (PubMed, Web of Science, MEDLINE, EBSCO, KCL-Korean Journal Dataset, SciELO Citation Index, and Derwent Innovations Index) and three Chinese databases (Wanfang Data, China Science and Technology Journal, and CNKI). Rigorous inclusion and exclusion criteria were applied.

Short-Term Effects of Ambient Air Pollution on Hospitalization for Respiratory Disease in Taiyuan, China: A Time-Series Analysis.

In this study, we estimated the short-term effects of ambient air pollution on respiratory disease hospitalization in Taiyuan, China. Daily data of respiratory disease hospitalization, daily concentration of ambient air pollutants and meteorological factors from 1 October 2014 to 30 September 2017 in Taiyuan were included in our study. We conducted a time-series study design and applied a generalized additive model to evaluate the association between every 10-μg/m³ increment of air pollutants and percent increase of respiratory disease hospitalization.

Interstitial Doppler optical coherence tomography.

Doppler optical coherence tomography (OCT) can image tissue structure and blood flow at micrometer-scale resolution but has limited imaging depth. We report a novel, linear-scanning, needle-based Doppler OCT system using angle-polished gradient-index or ball-lensed fibers. A prototype system with a 19-guage (diameter of approximately 0.

Management of late distant metastases after trimodality therapy for esophageal cancer.

Trimodality therapy has been shown in preliminary studies to increase survival in esophageal cancer. Distant recurrence remains the main pattern of failure. A case of aggressive treatment of two metachronous solitary visceral metastases is presented.

Thoracoscopy/laparoscopy in the staging of esophageal cancer: Maryland experience.

Precise clinical staging of esophageal cancer before treatment is important. Thoracoscopic/laparoscopic (Ts/Ls) staging has been proposed as a promising staging method. This study was conducted to evaluate the potential benefits of Ts/Ls staging over conventional noninvasive clinical staging in patients with esophageal cancer.
