We believe that a high percentage of covid-19 infections could be due to the presence of false negative (FN) individuals on rapid swabs. To support this hypothesis and quantify their number, we performed simulations using Bayes' rule and various assumptions about the sensitivity, specificity of swabs and prevalence of infection. Imagining FNs in liberty, we then calculated the probability of encountering them in groups of people with a typical number of habitual sites, such as: bus, supermarket, theatre, etc. The probability of encountering FN from rapid tests was more than 3 times higher (345% change) that reported by the RT-PCR test.

Predictive Value of Dynamic Contrast-Enhanced Breast Magnetic Resonance Imaging and Diffusion-Weighted Imaging Findings for Sentinel Lymph Node Metastasis in Early-Stage Invasive Breast Cancer.
Br J Radiol
January 2025
Department of Radiology, Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital, Ankara, TURKEY.
Objective: This retrospective study aimed to evaluate the predictive value of the preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) findings of mass lesions for predicting sentinel lymph node (SLN) metastasis in early breast cancer.
Methods: A total of 310 patients with suspicious mass lesions detected in preoperative MRI who subsequently underwent surgery and SLN biopsy (SLNB) between September 2015 and September 2022 were analyzed. The relationship between DCE-MRI and DWI findings and SLNB positivity was analyzed.
Unlocking Vision Care Accessibility: Evaluating Caregivers' Willingness to Pay in Specialised Eye Clinics for Family Members With Intellectual Disabilities.
J Intellect Disabil Res
January 2025
Institute of Public Health, School of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan.
Background: People with intellectual disabilities (IDs) require more vision care but encounter considerable challenges during eye examinations. Specialised clinics established specifically for people with IDs are generally limited. This study aims to evaluate primary family caregivers' willingness to pay (WTP) for specialised ophthalmology services designed for people with IDs.

Health Services Research, Faculty of Health, School of Medicine, Witten/Herdecke University, Witten, Germany.
Objective: Various demographic factors, including sex, socioeconomic status, and immigration status, have been linked to disparities in healthcare outcomes. Despite efforts by healthcare providers to address these inequities, interventions are not always effective. The present investigation provides empirical insights from Germany focusing on patients with systemic connective tissue disorders, highlighting the need for evaluated strategies to mitigate healthcare disparities.

Heart Rhythm
January 2025
Office of Science and Engineering Laboratories, Center for Devices and Radiological Health, Food and Drug Administration, Silver Spring, MD, USA. Electronic address:
Background: Spontaneously occurring life threatening reentrant arrhythmias result when a propagating premature beat encounters a region with significant dispersion of refractoriness. Although localized structural tissue heterogeneities and prescribed cell functional gradients have been incorporated into computational electrophysiological models, a quantitative framework for the evolution from normal to abnormal behavior that occurs via disease is lacking.
Objective: The purpose of this study was to develop a probabilistic modeling framework that represents the complex interplay of cell function and tissue structure in health and disease which predicts the emergence of premature beats and the initiation of reentry.
Development and Validation of a Routine Electronic Health Record-Based Delirium Prediction Model for Surgical Patients Without Dementia: Retrospective Case-Control Study.
JMIR Perioper Med
January 2025
Department of Surgery, Indiana University School of Medicine, Indianapolis, IN, United States.
Background: Postoperative delirium (POD) is a common complication after major surgery and is associated with poor outcomes in older adults. Early identification of patients at high risk of POD can enable targeted prevention efforts. However, existing POD prediction models require inpatient data collected during the hospital stay, which delays predictions and limits scalability.
