The purpose of this notice is to obtain information regarding: (1) the availability and capability of qualified small business sources; (2) whether they are small businesses; HUBZone small businesses; service-disabled, veteran-owned small businesses; 8(a) small businesses; veteran-owned small businesses; woman-owned small businesses; or small disadvantaged businesses; and (3) their size classification relative to the North American Industry Classification System (NAICS) code for the proposed acquisition. Your responses to the information requested will assist the Government in determining the appropriate acquisition method, including whether a set-aside is possible. An organization that is not considered a small business under the applicable NAICS code should not submit a response to this notice. This notice is issued to help determine the availability of qualified companies technically capable of meeting the Government requirement and to determine the method of acquisition. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. Responses will not be considered as proposals or quotes. No award will be made as a result of this notice. The Government will NOT be responsible for any costs incurred by the respondents to this notice. This notice is strictly for research and information purposes only. BACKGROUND The Healthy Aging in Neighborhoods of Diversity across the Life Span study (HANDLS) is a multidisciplinary, community-based, prospective longitudinal epidemiologic NIA study examining the influences of race and socioeconomic status (SES) on the development of age-related health disparities among socioeconomically diverse African Americans and whites in Baltimore. This study investigates whether health disparities develop or persist due to differences in SES, differences in race, or their interaction. This study is unique because it will assess over 20-years physical parameters as well as evaluate genetic, biologic, demographic, psychosocial, and psychophysiological parameters of African American and white participants in higher and lower SES. It also employs novel research tools, mobile medical research vehicles, in hopes of improving participation rates and retention among non-traditional research participants. DXA measures of body composition and bone mineral density are among the clinical measures acquired during participants' examinations in every wave. Body composition - the extent of lean and fat mass in various body regions - are important indicators of health. Measures of lean and fat mass are also important correlates required for thorough analyses of every domain examined by HANDLS such as risks for cardiovascular disease, diabetes, and kidney disease, changes in brain health assessed by MRI measures, and the influences of overall activity on health. Bone mineral density - a measure of bone strength - is a primary indicator of osteopenia and osteoporosis, both of which may lead to disabling bone fractures and loss of mobility. PURPOSE AND OBJECTIVES The purpose of this requirement is to procure quality expert services reviewing and analyzing existing Dual-energy X-ray Absorptiometry (DXA) body composition and bone mineral density data acquired on participants in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. PROJECT REQUIREMENTS I. The Contractor shall review total body, hip, and spine DXA image data provided by the Government from DXA scans acquired from HANDLS participants since 2004. Contractor shall manipulate scans revising them in diagnostic software to insure consistency in the designations of all regions of interest for each participant over time and among all participants. The goal is to define the same regions of interest within and among participants so that analyses of demographic differences and longitudinal change are assured that differences are not contaminated by differing definitions of body parts. A) Contractor shall have licensed software and current versions of Hologic and GE Lunar software installed on workstations. B) Contractor shall have necessary hardware and software to read data stored on legacy Iomega Zip drives. C) Contractor shall calibrate the validity of acquired measures using standard manufacturers' phantom scans for performing quality control of the stability of DXA measures over time. D) Contractor shall have established methods for scoring whole images as well as anatomical sub-regions for validity of measures (BMD, BMC, Fat, Lean) E) Contractor shall have established methods for scoring the technologist avoidable errors that caused a degradation in study data quality. F) Contractor shall establish standard operating procedures (SOP) for performing the above analysis as well as outlining the training needed for staff to perform the analysis G) Contractor shall have established validation data and statistical methods outlined in an SOP to document the vendor's reader accuracy and quality. H) Contractor shall have established expert review protocol and SOP for vendor expert to periodically review performance of vendor reader. II. Using software tools available to the Contractor or software tools supplied by DXA manufactures, the Contractor shall harmonize data acquired for the Lunar DXA with data subsequently acquired from the Hologic scanner. The goal of this requirement is to create a harmonized data file so that HANDLS investigators can examine change in body composition and bone mineral density from wave 1 for all participants. Data from Lunar scans were stored by the DXA computer in Iomega Zip drives, a technology not readily available since then. Zip drives are a removable floppy disk storage system produced by Iomega in 1994. The Contractor shall have the working means to read data nondestructively stored on Zip drives. This is particularly important because the only source for these data reside on these original Zip drives, which were the backup media for the DXA computer. A) Contractor shall have a variety of archive technology used over the last 30 years in DXA to assure that all archived scans can be read. These media technology include Zip (100, 250, 750 MB formats), Magneto Optical, DVD, and CD drives. B) Contractor shall be able to create new master archive storage for all GE and Hologic study compatible with manufacturer workstations, and transferable to the sponsor on hardwire-encrypted hard drives. C) Contractor shall have demonstrable experience with the creation and use of cross-calibration equations for DXA for spine, hip, and whole body scans. D) Contractor shall have demonstrable experience in longitudinal correction and calibration of DXA data for each of the scan types using CUSUM and existing phantom data. REPORTS/DELIVERABLES The following reports will be required: (1) A semi-annual report. (2) A Quality Assurance Protocol. (3) A final report shall be submitted before the expiration date of this contract. The Final Report shall be prepared in the same format as the semi-annual reports and shall include a summation of the work performed under the entire contract period of performance. ANTICIPATED PERIOD OF PERFORMANCE The period of performance for this acquisition will consist of one 12-month base period and three 12-month option periods.
