231 Background: Eye-tracking research has demonstrated that heterosexual men with normal testosterone levels attend visually to features of women associated with fertility, notably their breast size and waist to hip ratio. As such, eye-tracking data can serve as an implicit measure of a man’s libido. Many treatments for prostate cancer (PCa)—in particular androgen deprivation therapy (ADT)—depress sexual interest in men, but there is no objective measure of the intensity of this effect. Here we explore whether eye-tracking can be used to quantify the impact of PCa treatments on men’s libido. Methods: We used an IRB-approved deception protocol to explore the validity of eye-tracking technology for assessing the level of sexual interest of PCa patients and normal controls. Three age-matched groups of heterosexual men aged 50 years and older were recruited. They were: PCa patients using ADT, PCa patients not using ADT, and healthy controls. Unaware that their eye movements were being tracked, all were exposed to photographs of female models, either fully clothed (neutral) or minimally clothed (sexy). Number and duration of eye fixations on target areas of the female models’ bodies were recorded. Results: Trends observed in our preliminary data suggest that men on ADT exhibit differential patterns of visual attention to sexual stimuli compared to men in the other two groups. Although confirmation with a larger sample size is required, such shifts in attention may provide an objective measure of the influence of cancer treatments on the libido of PCa patients. Conclusions: Eye-tracking technology may provide a reliable and objective technique for measuring the libido of cancer patients. Such data could help patients be better informed about psychological side effects when making treatment decisions. They could also lead to ways to both study and reduce the impact of PCa treatments on men’s sexual interest.

e17056 Background: Prior cardio-oncology research has focused on examining the future risk of CVD as a result of cancer treatments. The impact of pre-existing CVD on cancer treatments is less clear. This study aimed to identify the associations of baseline CVD on treatment patterns and survival outcomes in metastatic prostate cancer where older age and exposure to androgen deprivation therapy can potentiate cardiac risks. Methods: We identified all patients diagnosed with metastatic prostate cancer in a large Canadian province from 2004 to 2017 using the population-based cancer registry. Administrative claims were linked to ascertain any diagnoses of pre-existing CVD, defined as any of arrythmias [AR], cerebrovascular accidents [CVAs], myocardial infarctions [MIs], or congestive heart failure [CHF] that preceded the diagnosis of metastatic prostate cancer. Logistic and Cox regression models were constructed to determine the associations of baseline CVD with receipt of cancer treatments (such as radiation, or systemic therapy) and overall survival (OS). Results: A total of 3,257 patients were included. The median age was 66 years (interquartile range, 46-95 years). At diagnosis of advanced prostate cancer, 993 (30.5%) had pre-existing CVD: 10.0% AR, 4.3% CVAs, 3.0% MIs, 2.8% CHF and 10.4% multiple CVDs. The Charlson comorbidity index (CCI) was 0, 1 and >1 in 53.4%, 27.3% and 19.3%, respectively. Overall, 2078 (63.8%) patients received chemotherapy, while 747 (22.9%) received radiotherapy. After adjusting for age and CCI, pre-existing CVD was associated with a lower likelihood of chemotherapy (odds ratio [OR], 0.67; 95% confidence interval [CI], 0.61-0.75; P=0.001) and radiotherapy (OR, 0.87; 95% CI, 0.85-0.91; P<0.001). Likewise, CVD was associated with worse OS, after adjusting for measured confounding variables (see table). Conclusions: One-third of patients with metastatic prostate cancer had pre-existing CVD, which was associated with a lower likelihood of chemotherapy and worse OS. In the context of an aging general population, early cardio-oncology consultations to optimize CVD management may lead to safer and broader uptake of appropriate prostate cancer treatments.[Table: see text]

Abstract Background The evaluation of gender-affirming facial feminization surgery (FFS) outcomes can be highly subjective, which has resulted in a limited understanding of the social perception of favorable gender and aesthetic facial appearance following these procedures. The growing use of eye-tracking technology in the assessment of surgical outcomes has introduced an objective measure of viewer subconscious gaze, which may provide more insight into how viewer characteristics may influence gaze, attention and perception of favorable FFS outcomes. Objective In this study, eye-tracking technology was used to measure attention and perception of surgery naïve cisgender female and feminized transgender faces, based on viewer gender identity. Methods Thirty-two participants (18 cisgender and 14 transgender) were enrolled and shown five photos each of surgery naïve cisgender female and feminized transgender faces. Gaze was captured using the Tobii X2 60 eye-tracking device (Tobii, Stockholm, Sweden) and participants rated the gender and aesthetic appearance of each face using Likert-type scales. Results Total image gaze fixation time did not differ by participant gender identity (6.00 vs 6.04 sec, p = 0.889), however, transgender participants spent more time evaluating the forehead/brow, buccal/mandibular regions and chin (p &lt; 0.001). Multivariate regression analysis showed significant associations between viewer gender identity, age, race, and education and the time spent evaluating gender salient facial features. Feminized faces were rated as more masculine with poorer aesthetic appearance than surgery naïve cisgender female faces, however, there was no significant difference in the distribution of gender appearance ratings assigned to each photo by cisgender and transgender participants. Conclusions These results demonstrate that gender identity influences subconscious attention and gaze on female faces. Even so, differences in gaze distribution did not correspond to subjective rated gender appearance for either surgery naïve cisgender female or feminized transgender faces, further illustrating the complexity of evaluating social perception of favorable FFS outcomes.

Abstract Purpose of Review The improvement in prostate cancer survival over time, even in those with advanced disease, has led to an increasing recognition of the impact of prostate cancer and its treatment on bone health. Cancer treatment–induced bone loss (CTIBL) is a well-recognized entity but greater awareness of the risks associated with CTIBL and its treatment is required. Recent Findings The principal culprit in causing CTIBL is hormonal ablation induced by prostate cancer treatment, including several new agents which have been developed in recent years which significantly improve survival, but may cause CTIBL. This review discusses the impact of prostate cancer and its treatment on bone health, including published evidence on the underlying pathophysiology, assessment of bone health, and strategies for prevention and treatment. Summary It is important to recognize the potential cumulative impact of systemic prostate cancer treatments on bone health.

Abstract The recent years have witnessed the emergence of new approaches in filmmaking including virtual reality (VR), which is meant to achieve an immersive viewing experience through advanced electronic devices, such as VR headsets. The VR industry is oriented toward developing content mainly in English and Japanese, leaving vast audiences unable to understand the original content or even enjoy this novel technology due to language barriers. This paper examines the impact of the subtitles on the viewing experience and behaviour of eight Arab participants in understanding the content in Arabic through eye tracking technology. It also provides an insight on the mechanism of watching a VR 360-degree documentary and the factors that lead viewers to favour one subtitling mode over the other in the spherical environment. For this end, a case study was designed to produce 120-degree subtitles and Follow Head Immediately subtitles, followed by the projection of the subtitled documentary through an eye tracking VR headset. The analysis of the eye tracking data is combined with post-viewing interviews in order to better understand the viewing experience of the Arab audience, their cognitive reception and the reasons leading to favour one type of subtitles over the other.

Abstract Background The objective assessment of beauty is challenging and subject to current research efforts. Recently, a new means of objectively determining the aesthetic appeal of body features has been investigated by analyzing gaze patterns and eye movements. Objectives The objective of this study was to assess differences in observers’ gaze patterns presented with standardized 3-dimensional images with different degrees of breast asymmetry using objective eye-tracking technology. Methods A total of 83 Caucasian study participants with a mean age of 38.60 (19.8) years were presented with 5 images depicting varying degrees of breast symmetry. In addition to the assessment of eye movements, participants were asked to rate the aesthetic appeal and the asymmetry of the breasts on a 5-point Likert scale. Results Overall, the data show that participants rating of the breasts’ aesthetic appeal was inversely related to the level of asymmetry. Time until fixation was shortest for the image depicting the greatest breast asymmetry (50 cc) with 0.77 (0.7), p &lt;0.001. In addition, the mammary region was also viewed longest in this image with 3.76 (0.5) seconds, p &lt; 0.001. A volume difference of 35 cc between breasts deflected the observers’ gaze significantly toward the larger of the asymmetrical breasts, p&lt;0.001. Conclusions Surgeons should focus on symmetrical breast volume (ie, differences &lt; 35 cc between breasts) to avoid noticeable asymmetry with regard to breast size.
