Background: Primary pulmonary lymphoepithelioma-like carcinoma (PLELC) is a rare subtype of non-small-cell lung cancer. This study aims to compare the efficacy and safety of perioperative PD-1/PD-L1 inhibitor plus chemotherapy versus chemotherapy alone in stage II-IIIB PLELC patients.
Patients And Methods: This retrospective study included stage II-IIIB PLELC patients.
Article Synopsis
- The study aimed to explore how non-drug treatments affect sarcopenic obesity (SO) through a meta-analysis of randomized controlled trials (RCTs).
- Results indicated that exercise and nutrition can improve various physical health metrics, such as body fat percentage (PBF) and grip strength, but individual interventions showed limited effectiveness.
- The combination of exercise and nutritional interventions proved to be the most effective approach for improving outcomes related to SO, highlighting the potential role of physical therapy as well.
Article Synopsis
- - Plant lipid transfer proteins (LTPs) are crucial for moving lipids between membranes, impacting pollen wall development, including the pollen aperture structure.
- - The study focuses on a rice mutant called pollen aperture defect 1 (Ospad1), which shows male sterility due to abnormal pollen grain development linked to a non-specific LTP that fails to properly bind lipids.
- - Researchers found that OsPAD1 interacts with a gene involved in pollen development, providing new insights into how LTPs function in forming pollen apertures, which could have broader implications for other cereal crops.
Recentering the humeral head does not necessarily improve glenohumeral abduction: A cadaveric biomechanical study.
Knee Surg Sports Traumatol Arthrosc
December 2024
Purpose: To explore if recentering the humeral head could improve shoulder abduction in shoulders with irreparable massive rotator cuff tears (IMRCTs).
Methods: Nine fresh-frozen cadaveric shoulders were used to simulate the intact condition and IMRCTs as controls. Four 'recenter' interventions were then sequentially applied: subacromial interposition (SI) using 4- and 8-mm spacers and superior capsule reconstruction (SCR) using two- and four-layer fascia lata grafts.
Development of a large-scale medical visual question-answering dataset.
Commun Med (Lond)
December 2024
Background: Medical Visual Question Answering (MedVQA) enhances diagnostic accuracy and healthcare delivery by leveraging artificial intelligence to interpret medical images. This study aims to redefine MedVQA as a generation task that mirrors human-machine interaction and to develop a model capable of integrating complex visual and textual information.
Methods: We constructed a large-scale medical visual-question answering dataset, PMC-VQA, containing 227,000 VQA pairs across 149,000 images that span various modalities and diseases.
