Monitoring SARS-CoV-2 variants with complementary surveillance systems: risk evaluation of the Omicron JN.1 variant in France, August 2023 to January 2024.

BackgroundEarly detection and characterisation of SARS-CoV-2 variants have been and continue to be essential for assessing their public health impact. In August 2023, Santé publique France implemented enhanced surveillance for BA.2.

Analysis of operant self-administration behaviors with supervised machine learning: Protocol for video acquisition and pose estimation analysis using DeepLabCut and Simple Behavioral Analysis (SimBA).

The use of supervised machine learning to approximate poses in video recordings allows for rapid and efficient analysis of complex behavioral profiles. Currently, there are limited protocols for automated analysis of operant self-administration behavior. We provide methodology to 1) obtain videos of training sessions via Raspberry Pi microcomputers or GoPros 2) obtain pose estimation data using the supervised machine learning software packages DeepLabCut (DLC) and Simple Behavioral Analysis (SimBA) with local high performance computer cluster, 3) comparison of standard MedPC lever response vs quadrant time data generated from pose estimation regions of interest and 4) generation of predictive behavioral classifiers.

Factors associated with interstitial lung disease and the progressive fibrosing phenotype in rheumatoid arthritis-related interstitial lung disease.

Background: The risk factors for interstitial lung disease (ILD) in rheumatoid arthritis (RA) are inconsistent among previous studies. Furthermore, the factors associated with the emergence of the recently defined progressive fibrosing (PF) phenotype are unknown. Herein, we analyze the risk factors for ILD in RA.

Giant Cystic Pneumocytoma in a Young Male: Rare Diagnostic Conundrum with Clinicoradiological and Histopathological Features.

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens.
