ABSTRACT
BACKGROUND: Developmental breast asymmetry (DBA) is a largely underreported condition where the natural growth of one breast is smaller than the other. While some degree of asymmetry or difference in size and shape is present in most women, DBA can result in more profound differences that can impact a woman's psychosocial well-being. OBJECTIVES: This study aims to better understand the experiences of women living with DBA, their experiences seeking treatment, and their reconstructive surgical journey and outcomes. DESIGN: This was a qualitative study involving in-depth, one-on-one semi-structured interviews with women diagnosed with DBA. METHODS: Participants were women seeking treatment for DBA through the Plastic and Reconstructive Surgery Unit at Flinders Medical Centre, a tertiary healthcare centre in Adelaide, South Australia. Interviews were recorded digitally, transcribed verbatim and analysed thematically. RESULTS: Fourteen interviews were conducted with 14 women; 13 women had completed their reconstruction and 1 was undergoing reconstruction at the time of their interview. Interviews highlighted the significant psychosocial impact of DBA, the different experiences in seeking help for DBA, the information received or lack thereof, the need for medical and social support throughout the surgical process, and the varied satisfaction with surgical outcomes. CONCLUSION: This study highlighted the subjective experiences of women who have grown up with DBA, improving our understanding of the significant psychosocial impact of DBA. Not all participants experienced post-operative improvements in psychosocial well-being due to surgical complications or unmet expectations. This study also demonstrated the need to raise awareness about DBA and the importance of additional medical and social support for women throughout their surgical journey.

Linguistic and ethnocultural diversity in long-term residential care is a growing trend in many urban settings. When long-term care staff and residents do not share the same language or ethnocultural background, the quality of their communication and care are jeopardized. There is very little research addressing how staff and residents communicate when they experience a mismatch in their language and ethnocultural backgrounds. Thus, the goals of the present study were to 1) document the verbal and nonverbal behaviours used by staff and residents in diverse interactions, and 2) identify and account for behaviours that either promoted or detracted from positive communication by drawing on principles from 'Communication Accommodation Theory'. Two long-term care facilities in British Columbia Canada were selected due to the diverse linguistic and ethnocultural backgrounds of their staff and residents. Twenty-seven staff and 27 residents consented to being video-recorded during routine activities (e.g., mealtimes, recreational activities). The recorded observations were transcribed, translated, and coded using qualitative descriptive and interpretive analyses. A number of verbal and nonverbal behaviours were identified and interpreted in relation to whether they promoted or detracted from positive communication. The findings point to considering a variety of proactive strategies that staff and administrators could employ to effectively accommodate to language and ethnocultural diversity in long-term care practice.

Disulfide bonds have been generally considered to be either structural or catalytic. Structural bonds stabilize a protein, while catalytic bonds mediate thiol-disulfide interchange reactions in substrate proteins. There is emerging evidence for a third type of disulfide bond that can control protein function by triggering a conformational change when it breaks and/or forms. These bonds can be thought of as allosteric disulfides. To better define the properties of allosteric disulfides, we have analyzed the geometry and dihedral strain of 6874 unique disulfide bonds in 2776 X-ray structures. A total of 20 types of disulfide bonds were identified in the dataset based on the sign of the five chi angles that make up the bond. The known allosteric disulfides were all contained in 1 of the 20 groups, the -RHStaple bonds. This bond group has a high mean potential energy and narrow energy distribution, which is consistent with a functional role. We suggest that the -RHStaple configuration is a hallmark of allosteric disulfides. About 1 in 15 of all structurally determined disulfides is a potential allosteric bond.
