Gaussian processes for time series with lead-lag effects with applications to biology data.

Investigating the relationship, particularly the lead-lag effect, between time series is a common question across various disciplines, especially when uncovering biological processes. However, analyzing time series presents several challenges. Firstly, due to technical reasons, the time points at which observations are made are not at uniform intervals.

The British Geriatrics Society's position on assisted dying.

In response to increased focus on the issue of Assisted Dying (AD) in the UK due to the presentation of The Terminally Ill Adults (End of Life) Bill 2024-25 [1] and bills before parliaments in the Isle of Man, Guernsey and Scotland, the British Geriatric Society (BGS) recently developed a position statement opposing legalisation of AD in the UK [2]. We set out our key reasoning behind this position, namely the current adverse health and social care context and significant concern about whether effective safeguards can be created to protect older people with complex needs from undue harms. The BGS asks for improved, personalised, multidisciplinary care for older people at the end of their lives, including high-quality palliative and end-of-life care.

Assessment of choroidal vessels in healthy eyes using 3-dimensional vascular maps and a semi-automated deep learning approach.

To assess the choroidal vessels in healthy eyes using a novel three-dimensional (3D) deep learning approach. In this cross-sectional retrospective study, swept-source OCT 6 × 6 mm scans on Plex Elite 9000 device were obtained. Automated segmentation of the choroidal layer was achieved using a deep-learning ResUNet model along with a volumetric smoothing approach.

Tuft cells transdifferentiate to neural-like progenitor cells in the progression of pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDA) is partly initiated through the transdifferentiation of acinar cells to metaplasia, which progresses to neoplasia and cancer. Tuft cells (TCs) are chemosensory cells not found in the normal pancreas but arise in cancer precursor lesions and diminish during progression to carcinoma. These metaplastic TCs (mTCs) suppress tumor progression through communication with the tumor microenvironment, but their fate during progression is unknown.

Self-Reported Penicillin Allergy and antibiotic use in critical care: An observational, retrospective study.

Background: Patients with Self-Reported Penicillin Allergy (SRPA) receive alternative antibiotics, which increase the length of stay and hospital costs, but the impact of SRPA on mortality in critically ill patients is not well described.

Methods: This was a single-center, retrospective analysis of routinely gathered clinical data for all intensive care unit (ICU) admissions over nine years. The primary outcome was 28-day mortality, which was analyzed using a time-to-event approach with multivariable models to adjust for confounding factors, including age, comorbidities, sex, and admission SOFA score (as a measure of organ dysfunction).
