Feasibility Study and Clinical Impact of Incorporating Breast Tissue Density in High-Risk Breast Cancer Screening Assessment.

Breast tissue density (BTD) is known to increase the risk of breast cancer but is not routinely used in the risk assessment of the population-based High-Risk Ontario Breast Screening Program (HROBSP). This prospective, IRB-approved study assessed the feasibility and impact of incorporating breast tissue density (BTD) into the risk assessment of women referred to HROBSP who were not genetic mutation carriers. All consecutive women aged 40-69 years who met criteria for HROBSP assessment and referred to Genetics from 1 December 2020 to 31 July 2021 had their lifetime risk calculated with and without BTD using Tyrer-Cuzick model version 8 (IBISv8) to gauge overall impact. McNemar's test was performed to compare eligibility with and without density. 140 women were referred, and 1 was excluded (BRCA gene mutation carrier and automatically eligible). Eight of 139 (5.8%) never had a mammogram, while 17/131 (13%) did not have BTD reported on their mammogram and required radiologist review. Of 131 patients, 22 (16.8%) were clinically impacted by incorporation of BTD: 9/131 (6.9%) became eligible for HROBSP, while 13/131 (9.9%) became ineligible (p = 0.394). It was feasible for the Genetics clinic to incorporate BTD for better risk stratification of eligible women. This did not significantly impact the number of eligible women while optimizing the use of high-risk supplemental MRI screening.

What is in a Name? Parent, Professional and Policy-Maker Conceptions of Consent-Related Language in the Context of Newborn Screening.

Newborn bloodspot screening programs are some of the longest running population screening programs internationally. Debate continues regarding the need for parents to give consent to having their child screened. Little attention has been paid to how meanings of consent-related terminology vary among stakeholders and the implications of this for practice. We undertook semi-structured interviews with parents (n = 32), healthcare professionals (n = 19) and policy decision makers (n = 17) in two Canadian provinces. Conceptions of consent-related terms revolved around seven factors within two broad domains, decision-making and information attainment. Decision-making comprised: parent decision authority; voluntariness; parent engagement with decision-making; and the process of enacting choice. Information ascertainment comprised: professional responsibilities (including disclosure of information and time to review); parent responsibilities; and the need for discussion and understanding prior to a decision. Our findings indicate that consent-related terms are variously understood, with substantive implications for practice. We suggest that consent procedures should be explained descriptively, regardless of approach, so there are clear indications of what is expected of parents and healthcare professionals. Support systems are required both to meet the educational needs of parents and families and to support healthcare professionals in delivering information in a manner in keeping with parent needs.

Consent for newborn screening: parents' and health-care professionals' experiences of consent in practice.

Consent processes for newborn bloodspot screening (NBS) are variable, with a lack of descriptive research that depicts how the offer of NBS is made to parents. We explored the experience, in practice, of consent for NBS. Semistructured interviews in two Canadian provinces were held with: (1) parents of children offered NBS (n=32); and (2) health-care professionals involved in the NBS process (n=19). Data on recollections of NBS, including consent processes, were utilized to identify emerging themes using the method of constant comparison. Three themes were relevant to NBS consent: (1) The 'offer' of NBS; (2) content and timing of information provision; and (3) the importance of parental experiences for consent decisions. Recollections of consent for NBS were similar between jurisdictions. Excepting midwives and their patients, NBS was viewed as a routine part of giving birth, with little evidence of an informed consent process. Although most parents were satisfied, all respondents suggested information about NBS be provided long before the birth. Accounts of parents who declined screening highlight the influence of parental experiences with the heel prick process in screening decisions. Findings further our understanding of consent in practice and highlight areas for improvement in parent-provider interactions.

New age eunuchs: motivation and rationale for voluntary castration.

We used a survey posted on the Internet to explore the motivation of men who are interested in being castrated. Out of 134 respondents, 23 (17%) reported already having been castrated. The 104 (78%) individuals who said they had not been castrated were asked why they wanted to be castrated and why they had not actualized that desire. They were given multiple-choice answers to select from. The major reason (selected by 40% of respondents) for desiring castration was to achieve a "eunuch calm" and freedom from sexual urges; however, a large proportion (approximately 30%) of respondents found fantasies about being castrated sexually exciting and a similar percentage desired castration for the "cosmetic" appearance it achieved (which we interpret to mean scrotal removal along with an orchiectomy). This high interest in castration as either a sexual stimulus (a fetish) or a cosmetic enhancement was unexpected and contrasted with the more classically stated motivation for voluntary castration in the psychiatric literature, i.e., libido control and transsexualism. Internet discussion groups that serve these men may encourage them to act out their castration fantasies. Alternately, Internet discussions may give them a displacement outlet for their fantasies and decrease the risk of castration by nonmedically qualified "street-cutters" or by self-mutilation. Forty percent of our respondents claimed that they would have an orchiectomy, if it were cheap, safe, and simple. A quarter wanted to try chemical castration first, but 40% were embarrassed to talk to their doctors about their interest in castration. Information now available on the Internet provides these men with increasingly easy access to street-cutters and directions on how to perform surgical castrations, putting them at risk of permanent injury and disability. Physicians need to be aware of these risks.
