Purpose: Diabetic retinopathy (DR) is a leading cause of vision loss worldwide, making early detection critical to prevent blindness. IDX-DR, an FDA-approved autonomous artificial intelligence (AI) system, has emerged as an innovative solution to improve access to DR screening. This systematic review and meta-analysis aimed to evaluate the diagnostic accuracy of IDX-DR in detecting diabetic retinopathy.
Design: Systematic review and meta-analysis METHODS: A comprehensive literature search was conducted across PubMed, Embase, Scopus and Web of Science, identifying studies published through October 5, 2024. Studies involving adult patients with Type 1 or Type 2 diabetes and reporting diagnostic metrics such as sensitivity and specificity were included. The primary outcomes were pooled sensitivity and specificity of IDX-DR. A bivariate random-effects model was used for meta-analysis, and summary receiver operating characteristic (SROC) curves were generated to assess diagnostic performance. Statistical analyses were performed using MetaDisc software version 2.0.
Results: Thirteen studies involving 13,233 participants met the inclusion criteria. IDX-DR's pooled sensitivity was 0.95 (95% CI: 0.82-0.99), and its pooled specificity was 0.91 (95% CI: 0.84-0.95). The SROC curve confirmed IDX-DR's high diagnostic accuracy in detecting diabetic retinopathy across various clinical environments. The AUC value of 0.95 demonstrated high sensitivity and specificity, indicating a robust diagnostic performance for IDX-DR in detecting diabetic retinopathy.
Conclusion: IDX-DR is a highly effective diagnostic tool for diabetic retinopathy screening, with robust sensitivity and good specificity. Its integration into clinical practice, especially in resource-limited settings, can potentially improve early detection and reduce vision loss. However, careful implementation is needed to address challenges such as over-diagnosis and ensure the tool complements clinical judgment. Future studies should explore the long-term impacts of AI-based screening and address ethical considerations surrounding its use.

Background: The prevalence of recreational drug use in myocardial infarction (MI) patients without standard modifiable cardiovascular risk factors (SMuRF) namely hypercholesterolemia, hypertension, diabetes and smoking, remains unknown.
Methods: All patients enrolled in The Addiction in Intensive Cardiac Care Units (ADDICT-ICCU) study, a French multicenter prospective observational study which systematically assessed the use of recreational drug within 2 h of admission, and presenting with MI but without known coronary artery disease were included. We compared patients with and without SMuRF.

Diabetes mellitus (DM) may lead to microvascular and macrovascular complications. Screening for these complications is crucial and non-invasive methods with high-dissemination potential are needed. Diabetic peripheral neuropathy (DPN) is particularly challenging to screen due to the lack of reliable clinical markers and endpoints.

Backgruound: Despite diabetes mellitus (DM) and pancreatitis being known risk factors for pancreatic cancer, patients with these conditions are not included in pancreatic cancer screening due to the low incidence of pancreatic cancer in these populations. This study aimed to determine the high-risk subgroup of patients with diabetes and pancreatitis that would benefit from pancreatic cancer screening.
Methods: A nested case-control study was conducted using data from the National Health Information Database of the Korean National Health Insurance Service.

Mucormycosis is a fungal infection caused by Mucorales fungi that cause severe disease and fatality, especially in immunocompromised individuals. Although vaccines and immunotherapeutics have been successful in combating viral and bacterial infections, approved antifungal immunotherapies are yet to be realized. To address this gap, monoclonal antibodies targeting invasive fungal infections have emerged as a promising approach, particularly for immunocompromised patients who are unlikely to maximally benefit from vaccines.

Mendelian randomization (MR) is a technique which uses genetic data to uncover causal relationships between variables. With the growing availability of large-scale biobank data, there is increasing interest in elucidating nuances in these relationships using MR. Stratified MR techniques such as doubly-ranked MR (DRMR) and residual stratification MR have been developed to identify nonlinearity in causal relationships.
