A systematic review and meta-analysis of 104 studies involving 71,298 ischemic stroke patients investigates the relationship between baseline white matter hyperintensities (WMH) and long-term clinical outcomes. The analysis, conducted by Marios K. Georgakis and published in 2020, pools relative risks for outcomes including dementia, functional impairment, recurrent stroke, and mortality, finding significant dose-response associations with WMH severity.
MRI data for validating a model-based acceleration technique for T1 mapping using Inversion-Recovery Look-Locker (IR-LL) sequences with radial acquisition. The validation study compared T1 values from accelerated reconstructions against a segmented IR gold standard, showing differences of less than 2.6% in a phantom and less than 5.5% in white and gray matter of seven healthy volunteers. The method can reconstruct a single-slice T1 map from data acquired in only 6 seconds.
Data from the SEVEL randomized controlled trial includes results from 138 ischemic stroke patients. The study compared early versus progressive sitting procedures, measuring outcomes like the modified Rankin score at 3 months and prevalence of medical complications. It was conducted by Fanny E. Herisson and published in 2020.
Featuring single-cell network profiling (SCNP) data from bone marrow and peripheral blood samples of 145 patients over 55 years old with acute myeloid leukemia (AML). It was used to train and validate a diagnostic classifier (DXSCNP) for predicting response to induction chemotherapy, achieving an AUROC of 0.76 in a verification set. The classifier's performance was compared against a clinical-only model (DXCLINICAL2).
Longitudinal MRI volume measurements and behavioral assessments from a study of HdhQ150 knock-in mice modeling Huntington's disease. It includes data on motor impairments, cognitive function, and regional brain atrophy tracked over 94 weeks. The study was conducted by Ivan Rattray and published in 2020.
Data from a randomized controlled trial of 184 asthma patients in South Korea, comparing video-based versus face-to-face inhaler technique education. The study measured primary and secondary outcomes including forced expiratory volume (FEV1) and asthma control test (ACT) scores over 12 weeks. It was conducted across 12 hospitals from November 2015 to June 2016.
Information on the distribution and use of medical immunobiological drugs for June 2020 under the CDC 'TSPMSD of the Talalay District Council'. The dataset was published by the States site of Ukraine and last updated on July 7, 2020.
This dataset supports a study introducing phase-diagram analysis from compressed sensing to X-ray computed tomography for determining sufficient projection counts. It contains data from three case studies comparing reconstruction performance across different sampling patterns and sparsity levels. The research was authored by Jakob S. Jørgensen and published in 2020.
Data from a study compares three airway segmentation methods using CT lung datasets from 17 patients. The dataset includes quantitative measures such as total branch length, number of branches, number of generations, and 3D model volume for each method. It was authored by Pall Jens Reynisson and published in 2020.
Finite-element method (FEM) simulations of microwave scattering from a three-dimensional human head model segmented into 21 tissue types. The data was generated to analyze the detection and classification of hemorrhagic and ischemic brain strokes by comparing electric field values and dielectric properties of normal and abnormal tissues. The simulations were conducted by Awais Munawar Qureshi and published in 2020.
United States outpatient prescription drug claims from 2007 to 2014 quantify polypharmacy across four billion patient-months. The data counts exposure incidences for combinations of up to five drug ingredients or ATC drug classes. Among patients taking any prescription drug, half are exposed to two or more drugs, and 5% are exposed to eight or more.
A cost-effectiveness analysis from a randomized controlled trial involving 600 older patients with cognitive impairment admitted for acute medical care. The study compares health and social care costs and quality-adjusted life years (QALYs) between a specialist Medical and Mental Health Unit and standard care over a 3-month follow-up period. Data includes total adjusted costs, QALY differences, and confidence intervals for 599 participants.
Data from a hospital-based bone bank in Taiwan contains a 20-year retrospective review of 3,979 allografts implanted in 3,193 recipients from July 1991 to June 2011. The registry tracks allograft sources, screening test results, harvest and implantation dates, and recipient outcomes. Analysis includes infection and discard rates, comparing recipients of sterile versus contaminated allografts.
3907 patient records detail the medical conditions of asylum seekers presenting at a field hospital in Brussels in September 2015. Physicians prospectively registered demographic and clinical characteristics, with over 49% showing features of infection. The data was collected by Médecins du Monde and published under a CC0 license.
Financial burden estimates for nine prevalent chronic diseases in Mexico, excluding cancer, based on the 2012 National Health and Nutrition Survey. The study calculates annual expenditure per patient and total financial burden for the Ministry of Health and the Mexican Institute of Social Security. Chronic kidney disease was the most expensive condition, with annual costs per patient exceeding US$8,966.
1,907,484 inpatient electronic health records from 12 general tertiary hospitals in eastern coastal China, covering 2003 to 2014. The data tracks the spectrum and trends of severe non-communicable diseases, with 50.05% male patients and 81.53% aged 50 or older. It was collected to dynamically monitor disease burden in a transitioning, economically developed region.
A cross-sectional study of 905 terminated clinical trials from the ClinicalTrials.gov results database as of February 2013. It characterizes the availability of primary outcome data and identifies reasons for trial termination, with 68% terminated for reasons other than accumulated trial data.
Featuring measurements from 29 termite mounds of three species, quantifying external and internal structure using photogrammetry and image analysis. It includes data on epigeal volume, surface area, basal area, macro-porosity, and micro-porosity, with comparisons to water-displacement and x-ray tomography methods. The data supports improved accuracy in estimating methane emissions from termite mounds.
This dataset quantifies the effectiveness of commercial and non-commercial metal artifact reduction (MAR) techniques for computed tomography. It compares techniques from three scanner vendors (Philips, GE, Siemens) and the freely available Metal Deletion Technique (MDT) using an anthropomorphic head and neck phantom with amalgam dental implants. The primary outcome measure is the average absolute error (AAE) reduction percentage for each technique.
4125 tumor samples from 14 gastrointestinal cancer sites were analyzed for tumor mutation load (TML), microsatellite instability (MSI), and PD-L1 expression. The data originates from a research study by Mohamed E. Salem, published in 2020, quantifying these biomarkers and their interrelationships. It includes findings such as TML-high prevalence ranging from 0% in GIST to 14.6% in right-sided colon cancer.
