Vulnerability of Older Adults to Government Impersonation Scams.

Importance: Financial fraud and scams targeting older adults are on the rise and pose serious public health and economic threats. Research on the vulnerability of older adults to fraud and scams relies almost exclusively on self-reported data, which have several intrinsic limitations. Thus, how older adults truly respond to fraud attempts remains unclear. Objective: To explore the vulnerability of older adults to a US government impersonation scam. Design, Setting, and Participants: This cross-sectional study, conducted from October to December 2021 among communities in the greater Chicago metropolitan area, was framed as a fictitious government agency reaching out to older adults about a potential compromise of personal information relevant to their Social Security and Medicare benefits. Participants were older adults participating in the Rush Memory and Aging Project, an ongoing cohort study of chronic conditions of aging. Data analysis was performed from February to August 2023. Exposures: Participants were exposed to deceptive materials through mailers, emails, and phone calls by a live agent. Main Outcomes and Measures: Based on the phone call data, participants were classified into 3 groups: no engagement (participants who did not answer the phone or call in), engagement (those who answered or called in but were skeptical about the legitimacy of the outreach and did not give away personal information), and conversion (participants who answered or called in without skepticism, or confirmed that they did not change their personal information, or provided the last 4 digits of their Social Security number). Results: A total of 644 older adults (501 [77.8%] female, 143 [22.2%] male), with a mean (SD) age of 85.6 (7.5) years, were included. A total of 441 (68.5%) participants did not engage, 97 (15.1%) engaged but raised skepticism, and 106 (16.4%) converted. Older adults who engaged but with skepticism had the highest cognition and financial literacy, while those in the conversion group had the lowest scam awareness. No differences were observed in psychological and other behavioral measures by the levels of engagement. Conclusions and Relevance: In this cross-sectional study using a behavioral experiment that mimicked a real-world imposter scam, a sizable number of older adults engaged without skepticism. Results suggest that many older adults, including those without cognitive impairment, are vulnerable to fraud and scams.

Phantom-based image quality assessment of clinical 18F-FDG protocols in digital PET/CT and comparison to conventional PMT-based PET/CT.

BACKGROUND: We assessed and compared image quality obtained with clinical 18F-FDG whole-body oncologic PET protocols used in three different, state-of-the-art digital PET/CT and two conventional PMT-based PET/CT devices. Our goal was to evaluate an  improved trade-off between administered activity (patient dose exposure/signal-to-noise ratio) and acquisition time (patient comfort) while preserving diagnostic information achievable with the recently introduced digital detector technology compared to previous analogue PET technology. METHODS: We performed list-mode (LM) PET acquisitions using a NEMA/IEC NU2 phantom, with activity concentrations of 5 kBq/mL and 25 kBq/mL for the background (9.5 L) and sphere inserts, respectively. For each device, reconstructions were obtained varying the image statistics (10, 30, 60, 90, 120, 180, and 300 s from LM data) and the number of iterations (range 1 to 10) in addition to the employed local clinical protocol setup. We measured for each reconstructed dataset: the quantitative cross-calibration, the image noise on the uniform background assessed by the coefficient of variation (COV), and the recovery coefficients (RCs) evaluated in the hot spheres. Additionally, we compared the characteristic time-activity-product (TAP) that is the product of scan time per bed position × mass-activity administered (in min·MBq/kg) across datasets. RESULTS: Good system cross-calibration was obtained for all tested datasets with < 6% deviation from the expected value was observed. For all clinical protocol settings, image noise was compatible with clinical interpretation (COV < 15%). Digital PET showed an improved background signal-to-noise ratio as compared to conventional PMT-based PET. RCs were comparable between digital and PMT-based PET datasets. Compared to PMT-based PET, digital systems provided comparable image quality with lower TAP (from ~ 40% less and up to 70% less). CONCLUSIONS: This study compared the achievable clinical image quality in three state-of-the-art digital PET/CT devices (from different vendors) as well as in two conventional PMT-based PET. Reported results show that a comparable image quality is achievable with a TAP reduction of ~ 40% in digital PET. This could lead to a significant reduction of the administered mass-activity and/or scan time with direct benefits in terms of dose exposure and patient comfort.

The waiting room as boundary and bridge between self-States and unformulated experience.

For both patient and analyst, the waiting room serves containing and expressive functions. The waiting room may serve as both a boundary between the analytic couple and a bridge to engagement. At times it can provide a means of titrating the intensity and duration of the affects activated by immersion in the analytic process: it can also serve to extend the boundaries of the analytic frame by providing a holding environment to facilitate metabolizing the impact of comings and goings. It also may be viewed as a membrane between self-states through which oscillating facets of dissociated or unformulated experience are enacted. Clinical material from the analysis of an adolescent girl illustrates these ideas.
