Background: It is reported that there is a significant relationship between the calcification of the aortic arch detected by chest X-ray examination and stroke. However, the relationship between stroke and aortic calcification (AoC) detected during a mass screening using a mobile helical computed tomography (CT) unit remains unknown.
Methods And Results: The study population consisted of 2,618 subjects (1,345 men, and 1,273 women; mean age, 52.9+/-13.8 years) who participated in a mass CT screening for lung cancer and tuberculosis. In the present study, 28 subjects (18 men, and 10 women; mean age, 65.9+/-13.5 years) had a past history of cerebral infarction. There were no subjects with a past history of intracerebral or subarachnoid hemorrhage. The frequency of AoC was significantly higher in the infarction group who were older than 50 years of age. In logistic regression analysis, the AoC was a stronger contributor of infarction than sex, age, and risk factors. Furthermore, the odds ratio of AoC for subjects with a past history of infarction increased as the number of calcified segments increased, and these values were 1.82 (95% confidence interval (CI) 1.06-3.15) in men, and 2.53 (95% CI 1.12-5.75) in women.
Conclusions: These results suggest that detection of AoC during mass chest screening using a mobile helical CT unit is an effective way to evaluate the risk of cerebral infarction.

Background: This study examines trends in delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) positivity rates in pre-employment urine drug screenings at a single university-based hospital occupational medicine clinic from 2017 to 2022, following California's recreational cannabis legalization in 2016, with sales beginning officially on January 1, 2018.
Methods: Retrospective analysis of 21,546 de-identified urine drug screenings from 2017 to 2022 was conducted. Initial screening used instant urine drug immunoassays (50 ng/mL cutoff for THC-COOH), followed by confirmatory gas chromatography-mass spectrometry (15 ng/mL cutoff).

Background: Artificial intelligence (AI) algorithms offer an effective solution to alleviate the burden of diabetic retinopathy (DR) screening in public health settings. However, there are challenges in translating diagnostic performance and its application when deployed in real-world conditions.
Objective: This study aimed to assess the technical feasibility of integration and diagnostic performance of validated DR screening (DRS) AI algorithms in real-world outpatient public health settings.

Congenital hearing loss is a significant health problem, with a worldwide incidence of >6 per 1000 live births. Late diagnosis will delay appropriate treatment, leading to potential neurodevelopment problems. Early diagnosis requires neonatal hearing screening, where one of the most used techniques is automated Auditory Brainstem Responses (aABR).

Single-cell surface-enhanced Raman scattering (SERS) has emerged as a powerful tool for precision medicine owing to its label-free detection, ultrasensitivity, and unique molecular fingerprinting. Unlike conventional bulk analysis, it enables detailed characterization of cellular heterogeneity, with particular promise in circulating tumor cell (CTC) identification, tumor microenvironment (TME) metabolic profiling, subcellular imaging, and drug sensitivity assessment. Coupled with microfluidic droplet systems, SERS supports high-throughput single-cell analysis and multiparametric screening, while integration with complementary modalities such as fluorescence microscopy and mass spectrometry enhances temporal and spatial resolution for monitoring live cells.

Incomplete biomass burning emits complex mixture of gaseous and particulate organic pollutants, yet their chemical speciation and toxicity have not been fully identified. This study profiled the organic fingerprinting primarily emitted from typical incomplete biomass burning through nontargeted analysis and estimated their toxic potencies. Gaseous organics exhibited 2.
