Analysis of Cephalometric Differences of the Midface and Upper Face in Males and Females: A Radiographic Study.

Gender affirmation facial surgery (GAFS) is an important component in treating gender dysphoria among transgender individuals by addressing gender incongruence of the face. There is a paucity of literature describing objective characterizations of the anatomic differences between male and female faces. In this study, cephalometric measurements were taken on routine CT imaging performed on cisgender patients between 2017 and 2020. Specifically defined cephalometric landmarks of the upper and midface were measured and compared between male and female cohorts. Thirty-eight patients, 19 male and 19 female, were identified for this study. Significant differences were identified in the frontal prominence, orbital size, malar height, bizygomatic width, nose, and upper lip, with moderate rates of specificity for each gender. Some important ratios are also presented. Differences in the malar region and the orbit highlight the importance of these areas as a point of focus for GAFS. These cephalometric findings provide objective evidence and parameters for perceived anatomic differences in male and female faces. In addition, they help both corroborate current surgical techniques as well as guide future approaches to GAFS.

CancerSupportSourceTM -Caregiver: Development of a distress screening measure for cancer caregivers.

OBJECTIVE: Given the substantial demands of cancer caregiving, practical and psychometrically sound tools to evaluate distress among cancer caregivers are needed. CancerSupportSourceTM -Caregiver is a distress screening, referral, and support program designed to identify the unmet needs of cancer caregivers and link caregivers to desired resources and support. This study refined and finalized the CancerSupportSource-Caregiver screening measure and examined its psychometric properties. METHODS: Using an analytic sample of 400 caregivers to people with cancer, we first performed item reduction by assessing exploratory factor analysis, external/internal item quality, and judging theoretical and practical implications of items. Confirmatory factor analysis along with reliability and validity analyses were then conducted to corroborate dimensionality and psychometric properties of the final measure. Nonparametric receiver operating characteristic curve analyses determined scoring thresholds for depression and anxiety risk subscales. RESULTS: Scale refinement resulted in an 18-item measure plus one screening item assessing tobacco and substance use. Items represented five domains of caregiver concerns: emotional well-being, patient well-being, caregiving tasks, finances, and healthy lifestyle. Our analyses showed strong internal consistency and test-retest reliability, a replicable factor structure, and adequate convergent, discriminant, and known groups validity. Sensitivity of 2-item depression and 2-item anxiety risk subscales were 0.95 and 0.87, respectively. CONCLUSIONS: CancerSupportSource-Caregiver is a reliable and valid multidimensional measure of caregiver distress that also screens for risk for clinically significant depression and anxiety. It can be implemented within a distress screening, referral, and follow-up program to rapidly assess caregivers' unmet needs and enhance caregiver well-being across the care continuum.

Analysis of Cephalometric Points in Male and Female Mandibles: An Application to Gender-Affirming Facial Surgery.

Gender-affirming facial surgery is a common intervention for transgender patients because of its ability to decrease the frequency of misgendering. Many anatomic targets can be addressed, but the mandible is the primary aspect of the lower third of the face that is manipulated during these procedures. This study's objective is to quantify the differences in cephalometric measurements between male and female mandibles on maxillofacial imaging, with the goal of identifying surgical targets for gender affirmation. A nonrandomized, retrospective, single-institution, case-control study of 387 patients who underwent maxillofacial computed tomography during 2017-2020 was performed. After excluding patients with imaging that did not capture the entire head or had deforming pathology of the face, a total of 113 patients were included. Cephalometric measurements that corresponded to areas reported by patients as sources of dysphoria were selected for analysis. These included mandibular width, ramus height, lateral flare, masseter volume, total face height, and the values of the mandibular angles in degrees. The relationship of masseter volume to the other measurements was also characterized. Significantly greater masseter volume was seen in males compared with females, and a greater masseter thickness was also seen in males. The mandibular angle was more acute in males than females. Aggregate analysis of muscle volume and thickness was positively correlated with ramus height, lateral flare, and mandibular width. Ramus, mental, and total facial height correlated directly with patient height in males but not in females. These data provide a normative baseline for planning lower facial gender-affirming surgery.

Magnetic resonance angiography of fetal vasculature at 3.0 T.

Magnetic resonance angiography has not been used much previously for visualizing fetal vessels in utero for reasons that include a contraindication for the use of exogenous contrast agents, maternal respiratory motion and fetal motion. In this work, we report the feasibility of using an appropriately modified clinical time-of-flight magnetic resonance imaging sequence for non-contrast angiography of human fetal and placental vessels at 3.0 T. Using this 2D angiography technique, it is possible to visualize fetal vascular networks in late pregnancy. KEY POINTS: • 3D-visualization of fetal vasculature is feasible using non-contrast MRA at 3.0 T. • Visualization of placental vasculature is also possible with this method. • Fetal MRA can serve as a vascular localizer for quantitative MRI studies. • This method can be extended to 1.5 T.

CancerSupportSource-Spanish: Development of a Distress Screening Measure for Spanish-Speaking Hispanic and Latino Individuals with Cancer.

Introduction: CancerSupportSource (CSS), a distress screening and referral program, identifies unmet needs of people with cancer and links them to resources and support. We developed and validated a Spanish-language version (CSS-Spanish) to better serve Hispanic and Latino communities and promote health equity. Methods: The 25-item CSS-Spanish was created leveraging rigorous translation methods and cognitive interviews to ensure cultural relevance and topical breadth. A total of 210 Spanish-speaking Hispanic and Latino individuals completed CSS-Spanish and comparison measures. Psychometric analyses examined dimensionality and statistical validation, and determined scoring thresholds for depression and anxiety risk subscales. Results: CSS-Spanish represented key concerns across five factors and exhibited strong internal consistency and test-retest reliability, convergent validity, and known-groups validity. Risk subscales demonstrated adequate sensitivity. Conclusion: CSS-Spanish is a reliable, valid multidimensional distress screener that rapidly assesses needs of Hispanic and Latino individuals. Embedded depression and anxiety risk flags can support staff in identifying those with high-acuity needs.
