- Abstract
Background: Transcranial magnetic stimulation (TMS) produces magnetic pulses by passing a strong electrical current through coils of wire. Repeated stimulation accumulates heat, which places practical constraints on experimental design. New method: We designed a condensation-free pre-chilled heat sink to extend the operational duration of transcranial magnetic stimulation coils. Results: The application of a pre-chilled heat sink reduced the rate of heating across all tests and extended the duration of stimulation before coil overheating, particularly in conditions where heat management was problematic. Comparison with existing method: Applying an external heat sink had the practical effect of extending the operational time of TMS coils by 5.8–19.3 minutes compared to standard operating procedures. Conclusion: Applying an external heat sink increases the quantity of data that can be collected within a single experimental session.

- Abstract
Introduction: Financial toxicity is common and pervasive among cancer patients. Research suggests that gynecologic cancer patients experiencing financial toxicity are at increased risk for engaging in harmful cost-coping strategies, including delaying/skipping treatment because of costs, or forsaking basic needs to pay medical bills. However, little is known about patients' preferences for interventions to address financial toxicity., Methods: Cross-sectional surveys to assess financial toxicity [Comprehensive Score for Financial Toxicity (COST)], cost-coping strategies, and preferences for intervention were conducted in a gynecologic cancer clinic waiting room. Associations with cost-coping were determined using multivariate modeling. Unadjusted odds ratios (ORs) explored associations between financial toxicity and intervention preferences., Results: Among 89 respondents, median COST score was 31.9 (IQR: 21-38); 35% (N = 30) scored < 26, indicating they were experiencing financial toxicity. Financial toxicity was significantly associated with cost-coping (adjusted OR = 3.32 95% CI: 1.08, 14.34). Intervention preferences included access to transportation vouchers (38%), understanding treatment costs up-front (35%), minimizing wait times (33%), access to free food at appointments (25%), and assistance with minimizing/eliminating insurance deductibles (23%). In unadjusted analyses, respondents experiencing financial toxicity were more likely to select transportation assistance (OR = 2.67, 95% CI: 1.04, 6.90), assistance with co-pays (OR = 9.17, 95% CI: 2.60, 32.26), and assistance with deductibles (OR = 12.20, 95% CI: 3.47, 43.48), than respondents not experiencing financial toxicity., Conclusions: Our findings confirm the presence of financial toxicity in gynecologic cancer patients, describe how patients attempt to cope with financial hardship, and provide insight into patients' needs for targeted interventions to mitigate the harm of financial toxicity., (© 2021.

- Abstract
Objective: To assess the feasibility of quantitatively measuring skin perfusion before and after suture or staple skin closure of vertical laparotomies using indocyanine green (ICG) uptake with near-infrared angiography., Methods: This was a prospective, non-randomized feasibility study of patients undergoing surgery with a gynecologic oncology service from 2/2018-8/2019. Feasibility was defined as the ability to quantitatively measure ICG uptake adjacent to the wound at the time of skin closure in ≥ 80% of patients. Patients were assigned suture or staple skin closure in a sequential, non-randomized fashion. Skin perfusion was recorded using a near-infrared imaging system after ICG injection and measured by video analysis at predefined points before and after skin closure. Clinicodemographic, pre- and intraoperative details, and surgical secondary events were recorded., Results: Of 20 participants, 10 were assigned staple closure and 10 suture closure. Two patients (10%) achieved objective quantification of ICG fluorescence before and after laparotomy closure, failing the predefined feasibility threshold of ≥ 80%. Reasons for failed quantification included overexposure (12), insufficient ICG signal uptake (6), and insufficient video quality (2). Near-infrared angiography wound perfusion was subjectively appreciated intraoperatively in 85% (17/20) of patients before and after wound closure., Conclusions: Objective assessment of laparotomy skin closure with near-infrared angiography-measured perfusion did not meet the pre-specified feasibility threshold. Adjustments to the protocol to minimize overexposure may be warranted. The ability to subjectively appreciate ICG perfusion with near-infrared angiography suggests a possible role for near-infrared angiography in the real-time intraoperative assessment of wound perfusion, particularly in high-risk patients., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

- Abstract
Objective: We report the incidence of occult nodal metastasis in patients who underwent primary surgical staging for apparent early endometrioid or serous endometrial cancer with bilateral SLN mapping and enhanced pathology. Occult ovarian metastasis rates were also reported., Methods: Patients with clinical stage I serous or endometrioid endometrial cancer who underwent primary staging surgery with successful bilateral SLN mapping from 1/2005-12/2018 were retrospectively evaluated. Rates of isolated tumor cells (ITCs), micro- and macrometastatic nodal disease, and occult ovarian involvement were reported., Results: Of 1044 patients, 959 had endometrioid and 85 serous carcinoma. There were no positive SLNs among 510 patients with noninvasive FIGO grade 1/2 endometrioid carcinoma and < 1%ITCs. Grade 1: 4.5%(9/202) with inner-half and 10%(6/62) with outer-half myoinvasion had positive SLNs. Grade 2: rates were 4%(3/76) and 20%(8/41), respectively. Grade 3: 5%(1/20) with noninvasive, 3%(1/31) with inner-half, and 24%(4/17) with outer-half myoinvasion had positive SLNs. ITC incidence increased with depth of myoinvasion-25% of deeply invasive grade 1/2 and 18% of deeply invasive grade 3 tumors. Four (10%) of 41 patients with noninvasive serous endometrial carcinoma had ITCs or positive SLNs. There were no occult ovarian metastases with grades 1/2 disease, 2/68 (3%) with grade 3 disease, and 2/85 (2%) with serous endometrial carcinoma., Conclusion: Ultrastaging SLNs may be unwarranted in low-grade noninvasive endometrioid cancer but valuable in noninvasive serous carcinoma. Occult ovarian metastasis is uncommon in early endometrial carcinoma and occurs in 2-3% of high-risk histologies. Further research is needed to determine ITC significance, particularly with regard to adjuvant treatment., Competing Interests: Declaration of competing interest Outside the submitted work, the authors claim the following potential disclosures: Dr. Leitao is an ad-hoc speaker for Intuitive Surgical, Inc. and is on the advisory board of JNJ/Ethicon.

- Abstract
Many studies suggest that aspects of culture be included in human immunodeficiency virus (HIV) education efforts in the United States. Few, however, clearly identify specific strategies that respond to the unique cultural issues of women of color. This article reviews the literature for culturally competent HIV prevention efforts for women of color--Latina, African American, Asian Pacific Islander, and Native American--and synthesizes components that need to be addressed in programs and interventions. Findings suggest that for programs to be culturally competent, both race/ethnicity and gender, along with population-specific, culturally based attitudes, beliefs, and behaviors, must be considered in interpersonal and organizational strategies.
