Partner presence in clinical conversations about sexual health: Breast cancer survivors', partners', and providers' perspectives of triadic interactions.

PURPOSE: Breast cancer survivors' (BCSs') sexual health (SH) clinical conversations are rarely studied from a dyadic perspective let alone from a triadic perspective. Using a triadic approach, we evaluated BCSs' comfort discussing SH with partners present and identified factors that can contribute to their comfort level. DESIGN: Qualitative approach using in-depth interviews. PARTICIPANTS: 93 BCSs, partners, and providers involved in BCS care. METHODS: In-depth interviews with BCSs, partners, and providers explored triadic perspectives to understand factors informing BCSs' comfort level. Thematic analysis was used to analyze data. FINDINGS: Four themes characterize potential benefits of partner presence: 1) partner facilitates information exchange, 2) partner realizes BCS's SH concerns are "a real thing," 3) partner better understands SH challenges, and 4) partner presence encourages relational communication about SH. Five themes illustrate potential complications of partner presence: 1) partner feels/becomes embarrassed, 2) partner is/becomes defensive, 3) partner presence constrains BCS's agency in clinical conversations, 4) partner presence threatens partner's view of BCS as a sexual being, and 5) partner presence increases partner burden. IMPLICATIONS FOR PSYCHOSOCIAL ONCOLOGY: Providers should (1) initiate conversations about BCS comfort with partner presence, (2) be aware of the interaction between BCS primary and secondary goals, (3) consider how BCS/partner goal conflicts obstruct BCS agency and sexual/relational health, and (4) offer opportunities to clarify goals and expectations, and coordinate therapeutic options.

[The geometry of the keel determines the behaviour of the tibial tray against torsional forces in total knee replacement]. / La geometría de la quilla condiciona el comportamiento de la bandeja tibial frente a fuerzas de torsión en prótesis totales de rodilla.

The keel design of the tibial tray is essential for the transmission of the majority of the forces to the peripheral bone structures, which have better mechanical proprieties, thus reducing the risk of loosening. The aim of the present study was to compare the behaviour of different tibial tray designs submitted to torsional forces. Four different tibial components were modelled. The 3-D reconstruction was made using the Mimics software. The solid elements were generated by SolidWorks. The finite elements study was done by Unigraphics. A torsional force of 6 Nm. applied to the lateral aspects of each tibial tray was simulated. The GENUTECH® tibial tray, with peripheral trabecular bone support, showed a lower displacement and less transmitted tensions under torsional forces. The results suggest that a tibial tray with more peripheral support behaves mechanically better than the other studied designs.
