Background: Despite the importance of early diagnosis of lung cancer and wide availability of chest radiography, the detection of operable stage lung cancer on chest radiographs (CXRs) remains challenging. This study aimed to investigate the effectiveness of artificial intelligence (AI)-based CXR analysis for detecting operable lung cancers.
Methods: Patients who underwent lung cancer surgery at two referral hospitals between March 2020 and February 2021 were retrospectively included in this study.
Purpose: In cases where rebiopsy fails to find the epidermal growth factor receptor (EGFR) T790M mutation, the criteria for selecting patients for repeated rebiopsy remains unclear. This study aimed to assess the impact of repeated rebiopsy on T790M mutation detection in non-small cell lung cancer (NSCLC) patients.
Methods: Patients with advanced EGFR-mutated NSCLC between January 2018 and December 2021 at three-referral hospitals in South Korea underwent retrospective review.
Article Synopsis
- The study investigates the effectiveness of AI in detecting lung nodules through chest X-rays (CXR) in non-respiratory outpatient clinics, highlighting its growing importance in medical diagnostics.
- Over a two-year period, the AI software detected lung nodules in 4.4% of CXR cases, leading to subsequent evaluations that identified lung cancers and other significant conditions in many patients.
- The findings underscore the potential of AI to improve patient diagnosis and management by revealing incidental lung nodules that may have otherwise gone unnoticed, supporting its integration into routine medical practice.
Article Synopsis
- This study investigates how often confirmatory tests are performed on women with abnormal cervical cytology in South Korea and what factors influence this rate.
- The analysis reveals that while abnormal Pap smear rates initially increased, they plateaued after 2016, and the rate of confirmatory tests significantly rose over the years from 2011 to 2021, especially for atypical cases.
- Key factors influencing the likelihood of undergoing confirmatory tests include the severity of the abnormal results, age, and location, while economic status did not significantly impact this likelihood.
This study addresses the propagation challenges faced by 'Shine Muscat', a newly introduced premium grapevine cultivar in South Korea, where multiple viral infections pose considerable economic loss. The primary objective was to establish a robust in vitro propagation method for producing disease-free grapes and to identify effective plant growth regulators to facilitate large-scale mass cultivation. After experimentation, 2.

Since older age is associated closely with development of chronic disease, it stands to reason that demographic changes will increase the proportion of older workers with chronic disease. The aim of the present study was to determine how chronic diseases affect employment status in Korea and the USA.

- A study analyzed whiteleg shrimp imported from Vietnam in South Korean markets for two viruses: IHHNV and WSSV.* -
- Out of 58 shrimp samples, IHHNV was found in 23 samples and WSSV in 2 samples using PCR and sequencing.* -
- This research marks the first detection of these viruses in imported shrimp, highlighting the need for improved awareness and stricter quarantine measures in South Korea.*
Background And Objectives: Recent studies have examined the structure-function relationship of high-density lipoprotein (HDL). This study aimed to identify and rank HDL-associated proteins involved in several biological function of HDL.
Methods: HDLs isolated from 48 participants were analyzed.
The Effect of Special Medical Examination for Night Shift Workers and Follow-Up Management Against Hypertension.
Int J Environ Res Public Health
February 2019
Background: Special health examination is a screening program introduced in 1973 in Korea to examine health problems of workers who are regularly exposed to 177 hazardous substances and physical environments specified by the Occupational Safety and Health Act. Shiftwork was added as a risk factor in 2013. The purpose of this study was to analyze changes of hypertension status after a special medical examination and subsequent follow-up management.

Methods: Thirty two patients were initially screened and HDLs of 21 patients were finally analyzed.
Article Synopsis
- The study investigates the effects of the recombinant elastase inhibitor guamerin (rEIG) on wound healing in mice, using two different models: a pin-punctured tongue wound and a linear excisional skin wound.
- Results showed that rEIG treatment led to increased inflammation and slower healing in the tongue wounds, while it accelerated healing in the excisional wounds with fibrin sealant by reducing inflammatory cell influx.
- The findings highlight the complex roles of rEIG in wound healing, suggesting it can worsen healing in contaminated wounds but enhance it in controlled environments by modulating inflammation.
