A publication issued by the Government Accountability Office with an abstract that begins "Since 1992, GAO has published long-term fiscal simulations showing federal deficits and debt under different sets of assumptions. GAO developed its long-term model in response to a bipartisan request from members of Congress concerned about the long-term effects of fiscal policy. GAO's simulations provide context for consideration of policy options. They are not intended to suggest particular policy choices but rather to help facilitate a dialogue on this important issue. GAO regularly updates its simulations as new data become available from the Congressional Budget Office (CBO) and the Social Security and Medicare Trustees (Trustees). This update incorporates provisions of the Budget Control Act. As in the past, GAO shows two simulations: The Baseline Extended simulation follows CBO's August 2011 baseline for the first 10 years and then holds revenue and spending other than interest on the debt and large entitlement programs (Social Security, Medicare, and Medicaid) constant as a share of gross domestic product (GDP). Revenue as a share of GDP over the entire period is higher than the historical averages; discretionary spending is below average. In the Alternative simulation, expiring tax provisions other than the temporary …

A letter report issued by the Government Accountability Office with an abstract that begins "In recent years, the United States experienced public health crises suspected to have been caused by the deliberate substitution or addition of harmful ingredients in food and drugs--specifically melamine in pet food and oversulfated chondroitin sulfate in the blood thinner heparin. These ingredients were evidently added to increase the apparent value of these products or reduce their production costs, an activity GAO refers to as economic adulteration. The Food and Drug Administration (FDA), an agency within the Department of Health and Human Services (HHS), has responsibility for protecting public health by ensuring the safety of a wide range of products that are vulnerable to economic adulteration. This report examines (1) the approaches that FDA uses to detect and prevent economic adulteration of food and medical products and (2) the challenges FDA faces in detecting and preventing economic adulteration and views of stakeholders on options for FDA to enhance its efforts to address economic adulteration. GAO reviewed FDA documents and interviewed FDA officials and stakeholders from academia and industry, among others.."

A letter report issued by the Government Accountability Office with an abstract that begins "On April 20, 2010, an explosion of the Deepwater Horizon oil rig leased by BP America Production Company (BP) resulted in a significant oil spill. GAO was requested to (1) identify the financial risks to the federal government resulting from oil spills, particularly Deepwater Horizon, (2) assess the Coast Guard's internal controls for ensuring that processes and payments for spill-related cost reimbursements and claims related to the spill are appropriate, and (3) describe the extent to which the federal government oversees the BP and Gulf Coast Claims Facility cost reimbursement and claims processes. We issued status reports in November 2010 and April 2011. This is the third and final report related to these objectives. We obtained and analyzed data on costs incurred from April 2010 through May 2011 and claims submitted and processed from September 2010 through May 2011. We reviewed relevant policies and procedures, interviewed officials and staff at key federal departments and agencies, and tested a sample of claims processed and cost reimbursements paid for compliance with internal controls.."

A publication issued by the Government Accountability Office with an abstract that begins "Traumatic brain injury (TBI) has emerged as a serious concern among U.S. forces serving in military operations in Afghanistan and Iraq. The widespread use of improvised explosive devices in these conflicts increases the likelihood that servicemembers will sustain a TBI, which the Department of Defense (DOD) defines as a traumatically induced structural injury and/or physiological disruption of brain function as a result of an external force. TBI cases within DOD are generally classified as mild, moderate, severe, or penetrating. From 2000 to March 2011 there were a total of 212,742 TBI cases reported by the Defense and Veterans Brain Injury Center within DOD. A majority of these cases, 163,181, were classified as mild traumatic brain injuries (mTBI)--commonly referred to as concussions. Early detection of injury is critical in TBI patient management. Diagnosis of moderate and severe TBI usually occurs in a timely manner due to the obvious and visible nature of the head injury. Identification of mTBI presents a challenge due to its less obvious nature. With mTBI, there may be no observable head injury. In addition, in the combat theater, an mTBI may not be identified …
