The Federal Transit Administration's National Transit Database (NTD) records the financial, operating and asset condition of transit systems. After data reporting was required by Congress in 1974, the NTD was set up to be the repository of data about the financial, operating and asset conditions of American transit systems. The NTD is designed to support local, state and regional planning efforts and help governments and other decision-makers make multi-year comparisons and perform trend analyses. It contains a wealth of information such as agency funding sources, inventories of vehicles and maintenance facilities, safety event reports, measures of transit service provided and consumed, and data on transit employees. Those receiving funding from the Urbanized Area Formula Program (5307) or Rural Formula Program (5311) – are required to submit data to the NTD in uniform categories. More than 660 transit providers report to the NTD through the Internet-based system.

B-cells play a pivotal role in several autoimmune diseases, including patients with immune-mediated neurological disorders (PIMND), such as neuromyelitis optica (NMO), multiple sclerosis (MS), and myasthenia gravis (MG). Targeting B-cells has been an effective approach in ameliorating both central and peripheral autoimmune diseases. However, there is a paucity of literature on the safety of continuous B-cell depletion over a long period of time. The aim of this study was to examine the long-term safety, incidence of infections, and malignancies in subjects receiving continuous therapy with a B-cell depleting agent rituximab over at least 3 years or longer. This was a retrospective study involving PIMND who received continuous cycles of rituximab infusions every 6 to 9 months for up to 7 years. The incidence of infection related adverse events (AE), serious adverse events (SAE), and malignancies were observed.

The Plug, a news site that focuses on the Black innovation economy, has been assembling a dataset of statements made by tech companies on racial justice, Black Lives Matter, and George Floyd. The dataset links to more than 200 statements so far and includes each company’s name, the timing of the statement, and other relevant context, such as the URL of their most recent diversity report and the percentage of employees and/or leaders who identify as Black.

The National Vital Statistics System (NVSS) provides the most complete data on births and deaths in the United States. These data are provided through contracts between the National Center for Health Statistics (NCHS) and vital registration systems operated in the various jurisdictions legally responsible for the registration of vital events – births, deaths, marriages, divorces, and fetal deaths.

The Large Truck Crash Causation Study (LTCCS) is based on a 3-year data collection project conducted by the Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation (DOT). LTCCS is the first-ever national study to attempt to determine the critical events and associated factors that contribute to serious large truck crashes allowing DOT and others to implement effective countermeasures to reduce the occurrence and severity of these crashes. The LTCCS documents 1,070 major crashes with approximately 1,000 variables on each crash obtained through driver, passenger, and witness interviews; crash scene, truck, and driver inspections, police reports; hospital records; and coroners' reports.

The National Conference of State Legislatures provides you with up-to-date, real-time information on law enforcement legislation that has been introduced in the 50 states and the District of Columbia. The database contains policing bills and executive orders introduced as of May 25, 2020, that are in response to recent events. Policing topics include oversight and data, training, standards and certification, use of force, technology, policing alternatives and collaboration, executive orders and other timely issues.

The NAEP data Explorer (NDE) creates customizable tables and graphics to display NAEP results. See the results of specific assessments across multiple years and broken down across a variety of student groups. For some assessments, results are available by state or by participating urban district. Results can be filtered by content areas within subjects. For in-depth exploration, the NDE provides statistical results such as significance testing, gap analysis, and regression analysis. You can export tables and charts to Word documents, Excel workbooks, and PDFs.

The Maternal Lifestyle Study (MLS) was the largest of the NIH longitudinal studies of children with prenatal cocaine exposure (PCE). MLS was a longitudinal multi-site observational study of the long-term effects of in-utero exposure to cocaine on child development. MLS was conducted at four geographically diverse, collaborating university centers (Wayne State University, University of Tennessee at Memphis, University of Miami, and Brown University). Participants were identified during the newborn period while in the hospital. The MLS began enrollment of a longitudinal birth cohort of 1,388 infant/mother dyads in 1993. Subjects in the follow-up were seen from 1 month of age through 16 years of age. The overall purpose of the study was to investigate the effects of drug use during pregnancy on acute neonatal events and long-term physical health, social, behavioral and neurodevelopmental outcomes.

The Behavioral Risk Factor Surveillance System (BRFSS) is a system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. BRFSS collects data in all 50 states as well as the District of Columbia and three U.S. territories. BRFSS collects state data about U.S. residents regarding their health-related risk behaviors and events, chronic health conditions, and use of preventive services. BRFSS also collects data on important emerging health issues such as vaccine shortage and influenza-like illness. Interviewers administer the annual BRFSS surveys continuously through the year.

SHELDUS™ is a county-level hazard data set for the U.S. and covers natural hazards such thunderstorms, hurricanes, floods, wildfires, and tornados as well as perils such as flash floods, heavy rainfall, etc. The database contains information on the date of an event, affected location (county and state) and the direct losses caused by the event (property and crop losses, injuries, and fatalities) from 1960 to present. With the release of Version 15.2, the database now also includes insured crop losses (indemnity payments). Insured crop losses cover the period from January 1989 to present. With the release of Version 18.1 (December 17, 2019), the database contains loss information for Puerto Rico, Guam, and other U.S. territories from 2010 through 2018.
