TEMPTED: time-informed dimensionality reduction for longitudinal microbiome studies.

Longitudinal studies are crucial for understanding complex microbiome dynamics and their link to health. We introduce TEMPoral TEnsor Decomposition (TEMPTED), a time-informed dimensionality reduction method for high-dimensional longitudinal data that treats time as a continuous variable, effectively characterizing temporal information and handling varying temporal sampling. TEMPTED captures key microbial dynamics, facilitates beta-diversity analysis, and enhances reproducibility by transferring learned representations to new data.

Early prediction of preeclampsia using the first trimester vaginal microbiome.

Preeclampsia is a severe obstetrical syndrome which contributes to 10-15% of all maternal deaths. Although the mechanisms underlying systemic damage in preeclampsia-such as impaired placentation, endothelial dysfunction, and immune dysregulation-are well studied, the initial triggers of the condition remain largely unknown. Furthermore, although the pathogenesis of preeclampsia begins early in pregnancy, there are no early diagnostics for this life-threatening syndrome, which is typically diagnosed much later, after systemic damage has already manifested.

Effects of aspirin and omega-3 fatty acids on composite and subdomain scores from the NEI-VFQ-25 questionnaire: the ASCEND-Eye randomized controlled trial.

Background: The double-blind, 2 × 2 factorial design, placebo-controlled ASCEND randomized trial compared the effects of 100 mg aspirin daily and, separately, 1 g omega-3 fatty acids (FAs) daily on the primary prevention of cardiovascular disease in 15,480 UK adults with diabetes. We report the effects of these randomized treatment allocations on scores derived from the National Eye Institute's Visual Function Questionnaire-25 (NEI-VFQ-25) in a subset of participants involved in the ASCEND-Eye sub-study.

Methods: Ordinal data from the NEI-VFQ-25 were analyzed using proportional odds regression methods.

The Ebola Data Platform: A prospective, standardised, clinical dataset collected during the 2013-2016 West African Ebola outbreak.

The Ebola Data Platform (EDP) was developed to strengthen knowledge and capacity across health, research, and humanitarian communities to reduce the impact of Ebola through responsible data use. This collaborative initiative was established by West African governments, NGOs, academic organisations, and intra-governmental health organisations directly involved in the 2013-2016 West African Ebola outbreak. The platform was established to provide a centralised, standardised dataset of individual patient data collected during the outbreak for the purpose of research to improve Ebola treatment and control, and includes over 13,600 patient records of individuals infected and treated from 22 different Ebola treatment centres across Guinea, Sierra Leone, Liberia, and Nigeria.

Clemastine Induces Oligodendrocyte Progenitor Pool Exhaustion and Senescence in the Context of Chronic Demyelination in a Rabbit Model.

Objectives: Clemastine has emerged as a promising therapy for the restoration of neurologic function in patients with multiple sclerosis (MS). However, clemastine and other agents with prodifferentiative effects on oligodendrocyte progenitor cells (OPCs) in rodent models have underperformed in clinical trials. We hypothesized that the preclinical studies showed more robust effects because of the abundance of OPCs in rodent models.
