Summary: By comparing the CT features of PSNs, significant differences were found in patient age, smoking history, and nodule morphology between benign and malignant PSNs. Malignant PSNs tend to have well-defined, lobulated nodules with irregular and scattered internal solid components. Lesion shape, density, and margin were not helpful in distinguishing malignant from benign PSNs.

Summary: This paragraph discusses the multiple lung cancer screening trials and studies conducted in Europe since 2011, following the promising results of the National Lung Screening Trial. It highlights the increasing importance of managing subsolid nodules, with guidelines and controversies existing around their optimal management. Follow-up imaging is crucial in the clinical assessment and management of subsolid nodules, as they can represent both benign and malignant lesions with varying clinical behavior.

Summary: The deep learning algorithm developed in this study showed excellent performance in estimating the malignancy risk of pulmonary nodules detected at screening CT, outperforming the PanCanadian model in certain cohorts and performing comparably to thoracic radiologists. This algorithm has the potential to provide reliable and reproducible malignancy risk scores for clinicians, which may help optimize management in lung cancer screening.

Summary: This study evaluated the performance of Lung-RADS and NELSON classifications in assessing nodules detected on follow-up lung cancer screening CT examinations. The results showed that clinical Lung-RADS achieved excellent performance, while volumetric assessments had weaker performance. Furthermore, new nodules warrant smaller size thresholds than existing nodules.

Summary: The study investigated CT features of pulmonary subsolid nodules in the size range of 5-20 mm and identified well-defined border, nodule thickness, and C/A ratio as significant predictors of malignancy. A predictive model combining these factors showed high accuracy and specificity in distinguishing focal interstitial fibrosis from adenocarcinoma.

Summary: This study evaluated the yield of short-term follow-up CT in showing growth among malignant nodules detected on lung cancer screening CT. The findings suggest that malignant nodules grow slowly on follow-up CT, and 3-month follow-up CT has a very low yield. Therefore, stability at 3-month follow-up should not instill high confidence in benignancy.

Summary: This study evaluated the use of the reticulation sign on thin-section CT images for predicting the invasiveness of pure ground-glass nodules (pGGNs). The reticulation sign was found to have high specificity in predicting invasiveness. Therefore, the presence of the reticulation sign on thin-section CT suggests a high suspicion of invasive adenocarcinoma.

Summary: Limited data are available regarding the management of subsolid nodules detected on lung cancer screening with low-dose CT (LDCT). This study aimed to determine the characteristics of screen-detected subsolid nodules and evaluate the probability of lung cancer and the clinical course of these nodules. Results showed a high rate of subsolid nodule detection on LDCT screening, particularly among never-smokers, with new subsolid nodules showing a lower probability of lung cancer and a higher likelihood of spontaneous resolution.

Summary: This article discusses the controversial issues and conditions surrounding subsolid pulmonary nodules commonly seen in Asia, including lack of guidelines, roles of preoperative biopsy and imaging, lesion location, selection of localization techniques, dissection and sampling of frozen sections and lymph nodes, multifocal lesions, and non-surgical treatment modalities. The aim is to provide updated evidence and opinions to assist surgeons and physicians in managing ground glass nodules in a balanced manner and encourage further discussion for better guidelines and algorithms.

Summary: This study evaluated the differences between heterogeneous ground-glass nodules (HGGNs) and part-solid nodules (PSNs) in lung cancer using grayscale histogram analysis. The results showed that histogram parameters were effective in differentiating between HGGNs and PSNs, as well as differentiating between different pathological types. Grayscale histogram analysis can be a useful tool in estimating the pathology of these lesions.

Summary: The increasing use of low-dose CT for lung cancer screening leads to the identification of many small, asymptomatic lung nodules and ground-glass opacities. Current guidelines suggest a conservative approach, but recent developments in thoracic surgery raise questions about the necessity of holding back on operative biopsy and resection. The option for early surgical therapy, especially with sublobar resection, is now being considered due to modern data suggesting the risk of inaction may be higher than expected.

Summary: The design and implementation of a novel heterostructure interface of La2Ni0.5Co0.5MnO6 nanoparticles and MoO3 nanobelt array-supported amorphous polyaniline (PANI; MoO3/P) have been developed for efficient oxygen evolution reaction (OER) and urea electrooxidation reaction (UOR). The optimized La2Ni0.5Co0.5MnO6@MoO3/P (LMP-30) showed excellent electrocatalytic performance with low overpotentials of 300 mV at 10 mA cm-2 (vs RHE) for OER and 0.48 V at 50 mA cm-2 (vs Hg/HgO) for UOR, as well as enhanced stability after 12-hour testing. This improved performance is attributed to the distinctive hierarchical nanostructure, offering synergistic effects on electrical characteristics and an electrochemically active surface area. Furthermore, the LNCM nanoparticles on the MoO3/P nanobelts provide more electrocatalytic active sites, efficient charge transport capacity, improved electrical properties, and strong electronic contacts.
