Factors associated with cancer disclosure in adolescent and young adult cancer survivors: An integrative review from the social-ecological model perspective.

PURPOSE: Young cancer survivors ("young survivors") may need to disclose their cancer experiences to reintegrate into society. In such cases, the recognition of social support through the disclosure of cancer experiences may prevent potential social disadvantages． This review aimed to describe the motivations, strategies and outcomes, and benefits and disadvantages of disclosure in young survivors based on the social-ecological model (SEM) to identify the support survivors need when disclosing their cancer experiences. METHODS: Using the integrated review methodology, we systematically searched six databases in English and Japanese as well as searched the reference lists of the selected studies. The themes identified via thematic analysis were categorized within the SEM levels. RESULTS: This review analyzed 14 studies and identified four themes, including "Motivation for Cancer Disclosure," "Barriers to Cancer Disclosure," "Consequences of Cancer Disclosure: Benefits," and "Consequences of Cancer Disclosure: Disadvantages." Motivations for young survivors to disclose their cancer involved post-cancer differences, perceptions, relationships, and social context. In navigating barriers, including self-stigma, peer exclusion, and discrimination, they employed strategies such as reassurance and information limitation. Tailored disclosure strategies at each SEM level offered social and psychological benefits, however, disadvantages, including stress, vulnerability, employment issues, and limited insurance coverage, were experienced by young survivors due to cancer disclosure. CONCLUSIONS: To optimize the benefits of cancer disclosure for young survivors, addressing psychological burdens, enhancing disclosure skills, offering familial psychological support, and fostering public awareness of cancer are essential.

Event-related potentials evoked by skin puncture reflect activation of Aß fibers: comparison with intraepidermal and transcutaneous electrical stimulations.

BACKGROUND: Recently, event-related potentials (ERPs) evoked by skin puncture, commonly used for blood sampling, have received attention as a pain assessment tool in neonates. However, their latency appears to be far shorter than the latency of ERPs evoked by intraepidermal electrical stimulation (IES), which selectively activates nociceptive Aδ and C fibers. To clarify this important issue, we examined whether ERPs evoked by skin puncture appropriately reflect central nociceptive processing, as is the case with IES. METHODS: In Experiment 1, we recorded evoked potentials to the click sound produced by a lance device (click-only), lance stimulation with the click sound (click+lance), or lance stimulation with white noise (WN+lance) in eight healthy adults to investigate the effect of the click sound on the ERP evoked by skin puncture. In Experiment 2, we tested 18 heathy adults and recorded evoked potentials to shallow lance stimulation (SL) with a blade that did not reach the dermis (0.1 mm insertion depth); normal lance stimulation (CL) (1 mm depth); transcutaneous electrical stimulation (ES), which mainly activates Aß fibers; and IES, which selectively activates Aδ fibers when low stimulation current intensities are applied. White noise was continuously presented during the experiments. The stimulations were applied to the hand dorsum. In the SL, the lance device did not touch the skin and the blade was inserted to a depth of 0.1 mm into the epidermis, where the free nerve endings of Aδ fibers are located, which minimized the tactile sensation caused by the device touching the skin and the activation of Aß fibers by the blade reaching the dermis. In the CL, as in clinical use, the lance device touched the skin and the blade reached a depth of 1 mm from the skin surface, i.e., the depth of the dermis at which the Aß fibers are located. RESULTS: The ERP N2 latencies for click-only (122 ± 2.9 ms) and click+lance (121 ± 6.5 ms) were significantly shorter than that for WN+lance (154 ± 7.1 ms). The ERP P2 latency for click-only (191 ± 11.3 ms) was significantly shorter than those for click+lance (249 ± 18.6 ms) and WN+lance (253 ± 11.2 ms). This suggests that the click sound shortens the N2 latency of the ERP evoked by skin puncture. The ERP N2 latencies for SL, CL, ES, and IES were 146 ± 8.3, 149 ± 9.9, 148 ± 13.1, and 197 ± 21.2 ms, respectively. The ERP P2 latencies were 250 ± 18.2, 251 ± 14.1, 237 ± 26.3, and 294 ± 30.0 ms, respectively. The ERP latency for SL was significantly shorter than that for IES and was similar to that for ES. This suggests that the penetration force generated by the blade of the lance device activates the Aß fibers, consequently shortening the ERP latency. CONCLUSIONS: Lance ERP may reflect the activation of Aß fibers rather than Aδ fibers. A pain index that correctly and reliably reflects nociceptive processing must be developed to improve pain assessment and management in neonates.

Can Event-Related Potentials Evoked by Heel Lance Assess Pain Processing in Neonates? A Systematic Review.

To clarify the possibility of event-related potential (ERP) evoked by heel lance in neonates as an index of pain assessment, knowledge acquired by and problems of the methods used in studies on ERP evoked by heel lance in neonates were systematically reviewed, including knowledge about Aδ and C fibers responding to noxious stimuli and Aß fibers responding to non-noxious stimuli. Of the 863 reports searched, 19 were selected for the final analysis. The following points were identified as problems for ERP evoked by heel lance in neonates to serve as a pain assessment index: (1) It is possible that the ERP evoked by heel lance reflected the activation of Aß fibers responding to non-noxious stimuli and not the activation of Aδ or C fibers responding to noxious stimulation; (2) Sample size calculation was presented in few studies, and the number of stimulation trials to obtain an averaged ERP was small. Accordingly, to establish ERP evoked by heel lance as a pain assessment in neonates, it is necessary to perform a study to clarify ERP evoked by Aδ- and C-fiber stimulations accompanied by heel lance in neonates.
