Concerns have been raised that glucagon-like peptide 1 receptor agonists (GLP1-RAs) may increase the risk of thyroid cancer, but evidence remains conflicting. We therefore investigated if GLP1-RA use, compared with use of dipeptidyl peptidase-4 inhibitors (DPP-4is), was associated with thyroid cancer risk in patients with type 2 diabetes. This multisite cohort study with subsequent meta-analysis included six population-based databases from Canada (Ontario), Denmark, Norway, South Korea, Sweden, and Taiwan.

Prcis: In a diverse database (All of Us), we report significant dose-response associations between alcohol use frequency and glaucoma, with alcohol use of 4 or more drinks per week associated with significantly increased odds of glaucoma.

Purpose: Current evidence on the association between alcohol use and primary open angle glaucoma (POAG) is mixed. We utilize the diverse All of Us Research Program to further examine this relationship.

Article Synopsis
  • The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
  • A special data scouting method is utilized to pick out events with low combined momentum in jets.
  • This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.

Children with systemic lupus erythematosus (SLE) are at increased risk of developing kidney disease, termed childhood-onset lupus nephritis (cLN). Single-cell transcriptomics of dissociated kidney tissue has advanced our understanding of LN pathogenesis, but loss of spatial resolution prevents interrogation of in situ cellular interactions. Using a technical advance in spatial transcriptomics, we generated a spatially resolved, single-cell resolution atlas of kidney tissue from eight patients with cLN and four control individuals.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

This study investigates the efficacy of predicting age-related macular degeneration (AMD) activity through deep neural networks (DNN) using a cross-instrument training dataset composed of Optical coherence tomography-angiography (OCTA) images from two different manufacturers. A retrospective cross-sectional study analyzed 2D vascular en-face OCTA images from Heidelberg Spectralis (1478 samples: 1102 training, 276 validation, 100 testing) and Optovue Solix (1003 samples: 754 training, 189 validation, 60 testing). OCTA scans were labeled based on clinical diagnoses and adjacent B-scan OCT fluid information, categorizing activity into normal, dry AMD, active wet AMD, and wet AMD in remission.

The first search for the Z boson decay to ττμμ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138  fb^{-1}. The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.

Article Synopsis
  • Heated tobacco products (HTPs) are considered potentially less harmful alternatives to traditional cigarettes, as they produce fewer toxicants.
  • A clinical study assessed the abuse liability (AL) of glo HTPs in two modes by comparing nicotine uptake and subjective effects to usual brand cigarettes and nicotine gum among healthy adult smokers.
  • Results indicated that glo HTPs led to significantly lower nicotine uptake and levels compared to regular cigarettes, suggesting they might be safer options for smokers.

Article Synopsis
  • The study focuses on PLA2G6-associated neurodegeneration (PLAN), which includes three diseases with similar symptoms, particularly highlighting infantile neuroaxonal dystrophy (INAD), a condition that affects vision and motor skills from an early age.
  • Researchers estimated the genetic prevalence of PLAN using two approaches: collecting genetic variant data from various databases and analyzing literature to find additional relevant variants. They determined that the estimated prevalence ranges from 1 in 987,267 to 1 in 1,570,079 pregnancies.
  • The findings indicate a significant underdiagnosis of PLAN and suggest a higher presence of PLA2G6 variants in African and Asian populations, emphasizing the need for better diagnostic efforts

Objective: Large language models such as ChatGPT have demonstrated significant potential in question-answering within ophthalmology, but there is a paucity of literature evaluating its ability to generate clinical assessments and discussions. The objectives of this study were to (1) assess the accuracy of assessment and plans generated by ChatGPT and (2) evaluate ophthalmologists' abilities to distinguish between responses generated by clinicians versus ChatGPT.

Design: Cross-sectional mixed-methods study.

Article Synopsis
  • The study investigates the link between glaucoma and allostatic load (AL), a concept for measuring the impact of chronic stress using various health biomarkers.
  • Conducted as a retrospective case-control analysis, it used data from the NIH All of Us Research Program, measuring AL through ten specific health indicators to compare individuals with and without primary glaucoma.
  • Results showed that those with glaucoma had higher AL scores, indicating increased stress-related health risks, with Black and Hispanic participants experiencing a more significant association with higher glaucoma risk compared to non-Hispanic Whites.

Clinical Relevance: Glaucoma is a complex eye condition with varied morphological and clinical presentations, making diagnosis and management challenging. The lack of a consensus definition for glaucoma or glaucomatous optic neuropathy further complicates the development of universal diagnostic tools. Developing robust artificial intelligence (AI) models for glaucoma screening is essential for early detection and treatment but faces significant obstacles.
