Disruptions in Lung Cancer Detection During COVID-19.

To quantify the extent of the disruption and recovery of lung cancer detection during the first two years of the pandemic, focusing on disparities across demographic and community factors. This retrospective cohort study used the SEER database to identify lung cancer cases from 2001 to 2021. Expected incidence rates for 2020 and 2021 were projected based on pre-pandemic trends (2000-2019) using the NCI's Joinpoint Regression program.

Revolutionizing cesium monitoring in seawater through electrochemical voltammetry and machine learning.

Monitoring radioactive cesium ions (Cs) in seawater is vital for environmental safety but remains challenging due to limitations in the accessibility, stability, and selectivity of traditional methods. This study presents an innovative approach that combines electrochemical voltammetry using nickel hexacyanoferrate (NiHCF) thin-film electrode with machine learning (ML) to enable accurate and portable detection of Cs. Optimizing the fabrication of NiHCF thin-film electrodes enabled the development of a robust sensor that generates cyclic voltammograms (CVs) sensitive to Cs⁺ concentrations as low as 1 ppb in synthetic seawater and 10 ppb in real seawater, with subtle changes in CV patterns caused by trace Cs⁺ effectively identified and analyzed using ML.

Salivary antigens rPagSP02 and rPagSP06 are a reliable composite biomarker for evaluating exposure to Phlebotomus argentipes in Sri Lanka.

Phlebotomus argentipes is the established vector of leishmaniasis in the Indian sub-continent. Antibodies to sand fly salivary antigens are biomarkers for vector-host exposure in leishmaniasis-endemic regions. Ph.

Reasons for Surgical Attrition Among Nonmetastatic Upper Gastrointestinal Cancer Patients: A Single Institutional Experience.

Introduction: Upper gastrointestinal (UGI) cancers require multidisciplinary treatment, but surgery provides the only potentially curative option. We sought to understand reasons for attrition before surgery within our regional hospital network.

Methods: We performed chart reviews of patients (age 18-80) with stage I-III UGI cancers (gastroesophageal junction, gastric, and hepatopancreatobiliary adenocarcinomas) in our multihospital cancer registry from 2015 to 2021.
