The unique-continuation property from sets of positive measure is here proven for the many-body magnetic Schrödinger equation. This property guarantees that if a solution of the Schrödinger equation vanishes on a set of positive measure, then it is identically zero. We explicitly consider potentials written as sums of either one-body or two-body functions, typical for Hamiltonians in many-body quantum mechanics. As a special case, we are able to treat atomic and molecular Hamiltonians. The unique-continuation property plays an important role in density-functional theories, which underpins its relevance in quantum chemistry.

Department of Rheumatology, Hanyang University Hospital for Rheumatic Diseases, Seoul, 04763, Republic of Korea.
To evaluate the incidence and risk of cardiovascular disease (CVD) among Korean patients with systemic lupus erythematosus (SLE) comparing them to diabetes patients and the general population. This nationwide cohort study focused on incident SLE patients aged over 40 years, matched with diabetes patients and the general population (1:4:4 ratio). CVD was defined as ischaemic heart disease, ischaemic stroke, and cardiac arrest.

Vegetation ecological restoration technology is widely regarded as an environmentally sustainable and green technology for the remediation of mineral waste. The appropriate ratio of amendments can improve the substrate environment for plant growth and increase the efficiency of ecological restoration. Herbs and shrubs are preferred for vegetation restoration in abandoned mines because of their rapid establishment and easy management.

Objectives: Depression is a chronic disorder that significantly affects functional decline in older adults, especially those with type 2 diabetes (T2D). Ethnic groups may experience different depression risks and severities, yet the effect of ethnicity on depression trajectories and specific dimensions in older adults with T2D remains largely unexamined. We examined the longitudinal associations of ethnicity with depression and its specific dimensions over time in older Ashkenazi and non-Ashkenazi Jews with T2D.

Institute of Applied Health Research, College of Medical and Dental Sciences, University of Birmingham, Birmingham, UK.
Objective: To develop and validate a prognostic model for risk-stratified monitoring of 5-aminosalicylate nephrotoxicity.
Methods: This UK retrospective cohort study used data from the Clinical Practice Research Datalink Aurum and Gold for model development and validation respectively. It included adults newly diagnosed with inflammatory bowel disease and established on 5-aminosalicylic acid (5-ASA) treatment between 1 January 2007 and 31 December 2019.
Differences in Postoperative Disposition by Kidney Disease Severity: A Population-Based Cohort Study.
Am J Kidney Dis
January 2025
Department of Community Health Sciences, University of Calgary, Calgary, Alberta, CANADA; O'Brien Institute for Public Health, Cumming School of Medicine, University of Calgary, Calgary, Alberta, CANADA.
Rationale & Objective: People with advanced kidney disease undergo more non-cardiac operations compared to the general population, with a higher risk of perioperative cardiac events and death. However, little is known about the associations between severity of preoperative kidney dysfunction with postoperative length of hospitalization and discharge disposition; these were the focus of this study.
Study Design: Population-based retrospective cohort.
