RESUMO

PURPOSE: Breast cancer-related arm lymphedema (BCRL) is a common chronic and debilitating condition that involves accumulation of lymphatic fluid in the arm or hand. Limited data are available on BCRL in African American women. Lack of physical activity (PA) and poor physical functioning (PF) are both associated with increased morbidity and mortality among breast cancer survivors. We examined the association of BCRL with PA and PF among African American breast cancer survivors. METHODS: 323 African American women who previously participated in a case-only study in three states (TN, GA, SC) completed a survivorship-focused questionnaire (mean: 4.2 years post-diagnosis) in 2015-2016. Validated measures were used to determine BCRL, PF, and PA. Adjusted binary logistic regression models estimated ORs and 95% CIs for the association of BCRL and meeting PA guidelines (≥ 150 min/week), while multinomial logistic regression was used for PF and PA (minutes/week) categorized based on tertiles. RESULTS: Approximately 32% reported BCRL since diagnosis; 25.4% reported BCRL in the last 12-months. About 26% and 50% reported that BCRL interfered with exercise and ability to do daily activities, respectively. The mean PF among those with BCRL was 51.0(SD:29.0) vs. 68.5(SD:30.1) among those without BCRL. BCRL was associated with lower PF (adjusted-OR for tertile 2: 2.12(95% CI:1.03-4.36) and adjusted-OR for tertile 1: 2.93(95% CI:1.44-5.96)). CONCLUSIONS: BCRL was associated with lower PF among long-term African American breast cancer survivors. Continued monitoring by health care professionals and increased education and behavioral interventions to support PA and improved PF among survivors living with BCRL are warranted.

RESUMO

Biomass and waste power generation holds the promise to secure electricity supply for a growing population and mitigate global warming simultaneously. Along with the increasing commission and installation of biomass/waste power units (BWPUs) across the globe, some BWPUs failures have been observed, including the cancellation of planned/commissioned BWPUs and the termination of those in operation before reaching their natural retirement. While empirical evidence suggests that factors like feedstock accessibility and policy instruments might affect the feasibility and performance of BWPUs, there is a lack of comprehensive investigation about why some BWPUs failed at the global scale. To fill this knowledge gap, this study quantifies the hazard ratio of BWPUs via a parametric survival analysis using a panel dataset covering a total of 12,829 BWPUs (relying on woody, non-woody, and waste biomass as raw feedstocks) located in 164 countries/regions worldwide for the period of 2001-2021. The analytical results suggest that large unit size is conducive to BWPUs failure, while feedstock accessibility and the implementation of policy instruments (including Feed-in-Tariff and carbon pricing) could largely reduce the hazard ratio of BWPUs, with varying impacts on BWPUs at the planned/commissioned stage or the operation stage, located in developed or developing countries. Our findings not only shed additional light on the fate of BWPUs, which is crucial to enriching our understanding about the development of the bioenergy sector worldwide, but also provide salient empirical evidence for policy-making in terms of ensuring feedstock accessibility, overcoming diseconomies of scale, and making fiscal instruments available and transparent to boost the confidence of investors and entrepreneurs in support of BWPUs development.

RESUMO

BACKGROUND: The decision to allocate hospitals for the initial reception of hostages abducted on the October 7th Hamas attack introduced an array of unprecedented challenges. These challenges stemmed from a paucity of existing literature and protocols, lack of information regarding captivity conditions, and variability in hostage characteristics and circumstances. OBJECTIVE: To describe the rapid development, implementation and evaluation of the Hostage-ReSPOND protocol, a comprehensive trauma-informed procedure for the care of hostages, including young children, their caregivers and families, immediately following their release from prolonged captivity. METHODS: A multidisciplinary expert focus group conducted a comprehensive literature review to develop the ReSPOND protocol, consisting of: Readiness of teams via multifaceted trainings, utilizing live simulations and video debriefings; Specialized professional teams experienced in providing holistic trauma-informed care; Personalized care tailored to individualized and developmentally-informed needs; Optimal safety rooted in creating a secure environment and trauma-informed response to young children, adolescents, caregivers and families; and Navigating Discharge, through coordination with community-based care systems. RESULTS: A designated facility at the Children's hospital was carefully prepared for receiving 29 hostages, aged 3.9-80 years, 28% under the age of 18. Implementation of the ReSPOND protocol, which prioritized holistic psychosocial interventions above urgent medical care, proved feasible and effective in managing the diverse and complex needs of returnees as per provider report. Finally, systemic assessment of returnee's immediate and long-term mental health needs proved highly challenging. CONCLUSIONS: There is currently no literature addressing the response to released hostages, especially those involving infants, young children and families within a children's hospital facility. This study has the potential to fill a crucial gap in knowledge by introducing a novel protocol which could offer valuable insights for public health organizations tasked with providing acute care to diverse individuals and families experiencing extreme, multi-layered mass traumatization.

RESUMO

BACKGROUND: YouTube is a platform for many topics, including plastic surgery. Previous studies have shown poor educational value in YouTube videos of plastic surgery procedures. The purpose of this study was to evaluate the quality and accuracy of YouTube videos concerning gynecomastia surgery (GS). METHODS: The phrases "gynecomastia surgery" (GS) and "man boobs surgery" (MB) were queried on YouTube. The first 50 videos for each search term were examined. The videos were rated using our novel Gynecomastia Surgery Specific Score to measure gynecomastia-specific information, the Patient Education Materials Assessment Tool (PEMAT) to measure understandability and actionability, and the Global Quality Scale to measure general quality. RESULTS: The most common upload source was a board-certified plastic surgeon (35%), and content category was surgery techniques and consultations (51%). Average scores for the Global Quality Scale (x̄ = 2.25), Gynecomastia Surgery Specific Score (x̄ = 3.50), and PEMAT Actionability (x̄ = 44.8%) were low, whereas PEMAT Understandability (x̄ = 77.4%) was moderate to high. There was no difference in all scoring modalities between the GS and MB groups. Internationally uploaded MB videos tended to originate from Asian countries, whereas GS videos tended to originate from non-US Western countries. Patient uploaders had higher PEMAT Actionability scores than plastic surgeon uploaders. CONCLUSIONS: The quality and amount of gynecomastia-specific information in GS videos on YouTube are low and contain few practical, take-home points for patients. However, understandability is adequate. Plastic surgeons and professional societies should strive to create high-quality medical media on platforms such as YouTube.

RESUMO

PURPOSE: Radiotherapy (RT) is the primary treatment for prostate cancer (PCa); however, the emergence of castration-resistant prostate cancer (CRPC) often leads to treatment failure and cancer-related deaths. In this study, we aimed to explore the use of microwave hyperthermia (MW-HT) to sensitize PCa to RT and investigate the underlying molecular mechanisms. METHODS: We developed a dedicated MW-HT heating setup, created an in vitro and in vivo MW-HT + RT treatment model for CRPC. We evaluated PC3 cell proliferation using CCK-8, colony experiments, DAPI staining, comet assay and ROS detection method. We also monitored nude mouse models of PCa during treatment, measured tumor weight, and calculated the tumor inhibition rate. Western blotting was used to detect DNA damage repair protein expression in PC3 cells and transplanted tumors. RESULTS: Compared to control, PC3 cell survival and clone formation rates decreased in RT + MW-HT group, demonstrating significant increase in apoptosis, ROS levels, and DNA damage. Lower tumor volumes and weights were observed in treatment groups. Ki-67 expression level was reduced in all treatment groups, with significant decrease in RT + MW-HT groups. The most significant apoptosis induction was confirmed in RT + MW-HT group by TUNEL staining. Protein expression levels of DNA-PKcs, ATM, ATR, and P53/P21 signaling pathways significantly decreased in RT + MW-HT groups. CONCLUSION: MW-HT + RT treatment significantly inhibited DNA damage repair by downregulating DNA-PKcs, ATM, ATR, and P53/P21 signaling pathways, leading to increased ROS levels, aggravate DNA damage, apoptosis, and necrosis in PC3 cells, a well-established model of CRPC.

RESUMO

Importance: Observational studies of survivors of breast cancer and prospective trials of aspirin for cardiovascular disease suggest improved breast cancer survival among aspirin users, but prospective studies of aspirin to prevent breast cancer recurrence are lacking. Objective: To determine whether aspirin decreases the risk of invasive cancer events among survivors of breast cancer. Design, Setting, and Participants: A011502, a phase 3, randomized, placebo-controlled, double-blind trial conducted in the United States and Canada with 3020 participants who had high-risk nonmetastatic breast cancer, enrolled participants from 534 sites from January 6, 2017, through December 4, 2020, with follow-up to March 4, 2023. Interventions: Participants were randomized (stratified for hormone receptor status [positive vs negative], body mass index [≤30 vs >30], stage II vs III, and time since diagnosis [<18 vs ≥18 months]) to receive 300 mg of aspirin (n = 1510) or placebo once daily (n = 1510) for 5 years. Main Outcomes and Measures: The primary outcome was invasive disease-free survival. Overall survival was a key secondary outcome. Results: A total of 3020 participants were randomized when the data and safety monitoring committee recommended suspending the study at the first interim analysis because the hazard ratio had crossed the prespecified futility bound. By median follow-up of 33.8 months (range, 0.1-72.6 months), 253 invasive disease-free survival events were observed (141 in the aspirin group and 112 in the placebo group), yielding a hazard ratio of 1.27 (95% CI, 0.99-1.63; P = .06). All invasive disease-free survival events, including death, invasive progression (both distant and locoregional), and new primary events, were numerically higher in the aspirin group, although the differences were not statistically significant. There was no difference in overall survival (hazard ratio, 1.19; 95% CI, 0.82-1.72). Rates of grades 3 and 4 adverse events were similar in both groups. Conclusion and Relevance: Among participants with high-risk nonmetastatic breast cancer, daily aspirin therapy did not improve risk of breast cancer recurrence or survival in early follow-up. Despite its promise and wide availability, aspirin should not be recommended as an adjuvant breast cancer treatment. Trial Registration: ClinicalTrials.gov Identifier: NCT02927249.

RESUMO

Background: Lower extremity (LE) trauma within the pediatric population may be debilitating and have different implications and etiologies than in adults. Specifically, lawnmower injuries can cause catastrophic sequelae to the lower extremities, often requiring complex reconstruction or resulting in amputation. This study aims to present our experience with pediatric LE lawnmower injuries at one of the busiest level 1 trauma centers in the United States. Methods: An IRB-approved retrospective analysis was performed studying pediatric patients (age <18 years) who experienced LE trauma due to a lawnmower injury over a 5-year period (2012-2017). Patient demographics, perioperative data, and types of reconstruction were reviewed. Univariate analysis of the data was performed to examine trends in exposure and management of pediatric LE lawnmower injuries. Results: Twenty-three patients were identified with pediatric LE lawnmower injuries, of whom 82.6% were male. The patients had a median age of 6 years and a median Injury Severity Score (ISS) of 4. Over one-third (34.8%) of this cohort required immediate amputation. Additionally, 26.1% and 8.7% required local and free flap reconstruction, respectively. In comparison, only 3.6% and 2.3% of all traumatic pediatric LE injuries from the same time frame required local and free flaps, respectively. Conclusions: Lawnmower injuries to the LE can be devastating, causing long-term physical, emotional, and psychosocial consequences for pediatric patients and their families. The data in this study suggest that pediatric LE injuries from lawnmowers more often require complex reconstruction than other traumatic LE injuries. Rapid and effective decision-making by experienced surgeons is necessary to optimize the potential for limb salvage in pediatric LE lawnmower injuries. An algorithm of recommendations on when to transfer these types of injuries to more experienced tertiary centers is provided. Additional resources should be dedicated toward improving public awareness and industrial safety features to help prevent lawnmower injuries in pediatric patients.

RESUMO

BACKGROUND & AIMS: Measurements (amount, distribution, and radiodensity) of muscle and adipose tissue were reported to be individually associated with overall survival in patients with breast cancer. However, they were not typically combined to develop an overall risk score, which can identify patients at high risk of death and prioritize patients in need of dietary and lifestyle interventions. Thus, we aimed to develop a novel composite body composition risk score (B-Score). METHODS: We included 3105 patients with stage II or III breast cancer at Kaiser Permanente Northern California and Dana Farber Cancer Institute. From CT scans at diagnosis, we assessed areas and radiodensity of muscle and adipose tissue at the third lumber vertebrae. We considered skeletal muscle index (SMI), subcutaneous adipose tissue index (SATI) and SAT radiodensity as they were independent prognostic factors for overall survival. Each measurement was dichotomized using optimal stratification, with low SMI (<40.1 cm2/m2), high SATI (≥75.7 cm2/m2), and high SAT radiodensity (≥-97.2HU) considered risk factors. We calculated B-Score as the sum of these factors and estimated its association with overall survival using Cox proportional hazards regression with adjustment for clinicopathologic factors. RESULTS: Mean (standard deviation) age was 53.9 (11.8) years, 70.3% were Non-Hispanic White, and 60.5% were stage II. Most patients (60.6%) had only one body composition risk factor (B-Score = 1). Compared to those with no risk factors (B-Score = 0), the risk of death increased with more body composition risk factors: the adjusted hazard ratios were 1.10 (95% CI: 0.85, 1.42), 1.47 (95% CI: 1.12, 1.92), and 2.11 (95% CI: 1.26, 3.53) for B-Scores of 1, 2, and 3, respectively (Ptrend < 0.001). CONCLUSIONS: More unfavorable body composition characteristics were associated with increased risks of overall mortality in a dose-response manner. Considering body composition measurements together as a composite score (B-Score) may improve risk stratification and inform dietary and lifestyle interventions following breast cancer diagnosis.

RESUMO

Clinicians working with older transgender and gender-diverse (TGD) individuals need to acquire the necessary knowledge and skills to provide care that is high quality and culturally appropriate. This includes supporting patients in their exploration of gender and attainment of gender-affirming medical interventions. Clinicians should strive to create environments that are inclusive and safe, and that will facilitate health care access and build constructive provider-patient relationships. Clinicians should be aware of best practices, including that age-appropriate health screenings should be anatomy based, and ensure that TGD older adults on gender-affirming hormone therapy (GAHT) receive ongoing laboratory monitoring and physical assessments, including serum hormone levels and biomarkers. Older TGD adults underutilize advance care planning, and need individualized assessments that consider their unique family structures, social support, and financial situation. End-of-life care services should ensure that TGD individuals are treated with dignity and respect.

RESUMO

PURPOSE: Cyclin-dependent kinase (CDK) 4/6 inhibitors (CDK4/6is) are an important component of treatment for hormone receptor-positive/human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC), but it is not known if patients might derive benefit from continuation of CDK4/6i with endocrine therapy beyond initial tumor progression or if the addition of checkpoint inhibitor therapy has value in this setting. METHODS: The randomized multicenter phase II PACE trial enrolled patients with hormone receptor-positive/HER2- MBC whose disease had progressed on previous CDK4/6i and aromatase inhibitor (AI) therapy. Patients were randomly assigned 1:2:1 to receive fulvestrant (F), fulvestrant plus palbociclib (F + P), or fulvestrant plus palbociclib and avelumab (F + P + A). The primary end point was investigator-assessed progression-free survival (PFS) in patients treated with F versus F + P. RESULTS: Overall, 220 patients were randomly assigned between September 2017 and February 2022. The median age was 57 years (range, 25-83 years). Most patients were postmenopausal (80.9%), and 40% were originally diagnosed with de novo MBC. Palbociclib was the most common previous CDK4/6i (90.9%). The median PFS was 4.8 months on F and 4.6 months on F + P (hazard ratio [HR], 1.11 [90% CI, 0.79 to 1.55]; P = .62). The median PFS on F + P + A was 8.1 months (HR v F, 0.75 [90% CI, 0.50 to 1.12]; P = .23). The difference in PFS with F + P and F + P + A versus F was greater among patients with baseline ESR1 and PIK3CA alterations. CONCLUSION: The addition of palbociclib to fulvestrant did not improve PFS versus fulvestrant alone among patients with hormone receptor-positive/HER2- MBC whose disease had progressed on a previous CDK4/6i plus AI. The increased PFS seen with the addition of avelumab warrants further investigation in this patient population.

RESUMO

Urban trees have attracted increasing attention to serve as a green prescription for addressing various challenges facing human society like climate change and environmental deterioration. However, without healthy growth of urban trees, they cannot service any environmental, social, and economic benefits in a sustainable manner. By monitoring the canopy development, the tree growth dynamics in different urban habitats can be detected and appropriate management approaches can be executed. Using the Kowloon Peninsula, Hong Kong, as a case, this study explores how remote sensing data can help monitor and understand the impacts of heterogeneous urban habitats on tree canopy dynamics. Four algorithms based on WorldView-2 satellite image are compared to optimize the canopy segmentation. Then the individual tree canopy is integrated with Sentinel-2 satellite data to obtain canopy growth dynamics for each season from 2016 to 2020. Three indicators are applied to reflect tree canopy status, including the fluorescence correction vegetation index (FCVI, tracking leaf chlorophyll density), the soil adjusted total vegetation index (SATVI, measuring the density of woody branches and twigs), and the normalised difference phenology index (NDPI, capturing canopy water content). And four heterogeneous habitats where urban trees stand are specified. The results revealed that urban trees show varying canopy growth status, in a descending order from natural terrains, parks, residential lands, to road verges, suggesting that urban habitats curtail trees' growth significantly. Additionally, two super-typhoons in 2017 and 2018, respectively, caused serious damages to tree canopy. Relevant resiliency of tree varies, echoing the sequence of canopy growth status with those in road verges the least resilient. This study shows how remote sensing data can be used to provide a better understanding of long-term tree canopy dynamics across large-scale heterogeneous urban habitats, which is key to monitoring and maintaining the health and growth of urban trees.

RESUMO

We aimed to examine the association between the use of metformin and other anti-diabetic medications and breast cancer incidence within two large prospective cohort studies. We followed 185,181 women who participated in the Nurses' Health Study (NHS; 1994-2016) and the NHSII (1995-2017), with baseline corresponding to the date metformin was approved for type 2 diabetes (T2D) treatment in the US Information on T2D diagnosis, anti-diabetes medications, and other covariates was self-reported at baseline and repeatedly assessed by follow-up questionnaires every 2 years. Breast cancer cases were self-reported and confirmed by medical record review. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between medication use and breast cancer were estimated using Cox proportional hazards regression models, adjusting for breast cancer risk factors. During 3,324,881 person-years of follow-up, we ascertained 9,192 incident invasive breast cancer cases, of which 451 were among women with T2D. Compared with women without T2D (n = 169,263), neither metformin use (HR = 0.97; 95% CI = 0.81-1.15) nor other anti-diabetic medications use (HR = 1.11; 95% CI = 0.90-1.36) associated with significantly lower breast cancer incidence. Among women with T2D (n = 15,918), compared with metformin never users, metformin ever use was not significantly inversely associated with breast cancer (HR = 0.92; 95% CI = 0.74-1.15). Although we observed that past use of metformin was inversely associated with breast cancer in the T2D population (HR = 0.67; 95% CI = 0.48-0.94), current use (HR = 1.01; 95% CI = 0.80-1.27) and longer duration of metformin use were not associated with breast cancer (each 2-year interval: HR = 1.01; 95% CI = 0.95-1.07). Overall, metformin use was not associated with the risk of developing breast cancer among the overall cohort population or among women with T2D.

RESUMO

Inflammatory breast cancer (IBC) is a highly aggressive subtype of breast cancer characterized by rapidly arising diffuse erythema and edema. Genomic studies have not identified consistent alterations and mechanisms that differentiate IBC from non-IBC tumors, suggesting that the microenvironment could be a potential driver of IBC phenotypes. Here, using single-cell RNA sequencing, multiplex staining, and serum analysis in patients with IBC, we identified enrichment of a subgroup of luminal progenitor (LP) cells containing high expression of the neurotropic cytokine pleiotrophin (PTN) in IBC tumors. PTN secreted by the LP cells promoted angiogenesis by directly interacting with the NRP1 receptor on endothelial tip cells located in both IBC tumors and the affected skin. NRP1 activation in tip cells led to recruitment of immature perivascular cells in the affected skin of IBC, which are correlated with increased angiogenesis and IBC metastasis. Together, these findings reveal a role for cross-talk between LPs, endothelial tip cells, and immature perivascular cells via PTN-NRP1 axis in the pathogenesis of IBC, which could lead to improved strategies for treating IBC. SIGNIFICANCE: Nonmalignant luminal progenitor cells expressing pleiotrophin promote angiogenesis by activating NRP1 and induce a prometastatic tumor microenvironment in inflammatory breast cancer, providing potential therapeutic targets for this aggressive breast cancer subtype.

RESUMO

INTRODUCTION: The National Institutes of Health recommends that patient education materials (PEMs) be written at the sixth grade level. However, PEMs online are still generally difficult to read. The usefulness of online PEMs depends on their comprehensibility. OBJECTIVES: This study assessed the readability of PEMs from national Plastic and Reconstructive Surgery (PRS) organization websites. METHODS: Patient education materials were collected from 3 prominent PRS organizations-the American Society of Plastic Surgeons (ASPS), American Society of Aesthetic Plastic Surgeons (ASAPS), and the American Society of Reconstructive Microsurgeons (ASRM). ASPS PEMs were organized into reconstructive and cosmetic groups, and then further subdivided into English and Spanish subgroups. ASAPS and ASRM PEMs provided cosmetic and reconstructive comparison groups to ASPS, respectively. Readability scores were generated using the Simple Measure of Gobbledygook (SMOG) and the Spanish SMOG scales. RESULTS: Overall, all PEMs failed to meet readability guidelines. Within ASPS, Spanish PEMs were easier to read than English PEMs ( P < 0.001), and cosmetic PEMs were easier to read than reconstructive PEMs ( P < 0.05). There was no significant difference between ASPS cosmetic and ASAPS PEMs ( P = 0.36), nor between ASPS reconstructive and ASRM PEMs ( P = 0.65). ASAPS and ASRM did not have any Spanish PEMs, and 92% of all ASPS PEMs were in English. CONCLUSION: Although PRS societies strive to better educate the public on the scope of PRS, PRS ranks lowly in public understanding of its role in patient care. In addition, Spanish language PEMs from the 3 PRS organizations are severely lacking. Addressing these concerns will make online patient resources more equitable for various patient populations.

RESUMO

Hong Kong (HK), one of the world's most densely populated metropolises, is home to over 200 rivers and streams extending about 2500 km in length. During the 1970s-1990s, most of these rivers were converted into artificial canals, to which the local society pays little attention. Since the 2010s, the HK government has initiated river revitalization to enhance the social-environmental roles of rivers. This study employed a mixed research method, including literature and policy analysis, expert interviews, field visits, and a public survey, to identify key challenges in HK's Integrated River Basin Management (IRBM). The findings highlighted the lack of IRBM's institutional arrangements in HK, characterized by a fragmented 'one river, two systems' approach without both coordination and collaboration. The Water Supplies Department (WSD) impounds upland streams as reservoirs for securing the local water supply, while the Drainage Service Department (DSD) manages heavily channelized, culverted downstream serving as storm drains with diminished ecological functionality. One significant barrier to the implementation of IRBM in HK was the limited public participation, although our survey revealed a high level of public willingness to participate in river management. Presently, river revitalization efforts have achieved limited success, with ecological measures appearing mostly "cosmetic" and the conservation of freshwater biodiversity neglected. This further underscored the pressing need for the embracement of IRBM in HK to safeguard basin-wide freshwater ecosystems. Our survey also indicated low public awareness of river revitalization initiatives and widespread dissatisfaction with their outcomes. In conclusion, we proposed the development of IRBM in HK by instituting river basin coordination, prioritizing river ecosystem restoration in revitalization projects, and involving the public through tailored strategies.

RESUMO

OBJECTIVE: Minority representation and promotion in medicine is lacking. Social media can facilitate change by raising awareness of biases, empowering others, and cultivating connections. The TimesUpPRS Instagram account was created in March 2020 to foster diversity, equity, and inclusion (DEI) in plastic surgery by celebrating surgeons of diverse identities and emphasizing the need to create safe, fair, and equitable workplaces. We aim to characterize its content, audience demographics, engagement, and impact. METHODS: All TimesUpPRS posts published until March 2022 were reviewed for content analysis. Audience demographics were assessed through Instagram Insights. Engagement was assessed through likes, comments, and posts tagging @TimesUpPRS. RESULTS: Three hundred fifty-five posts have been published, with 45.9% original content. These posts discuss representation or treatment of women (39.7%), Black (24.2%), Asian and Pacific Islander (14.4%), LGBTQ+ (12.7%), LatinX (6.5%), people of color overall (4.8%), first generation-low income (1.7%), and Native American (1.1%) individuals. 45.1% aimed to raise social awareness, 19.4% spotlighted plastic surgery figures, 16.3% highlighted research, and 5.6% advertised opportunities for community involvement. The mean (SE) number of hashtags utilized was 10.9 (0.6), with #ilooklikeasurgeon used most. There were 2052 followers, but 10,025 accounts reached. Of reached accounts, 66.8% were women, 71.8% were from the U.S., and 55% were aged 25 to 34. The mean (SE) number of likes and comments per post was 62.2 (3.4) and 2.6 (0.2). 85.0% of comments were supportive. Three hundred sixty-six posts tagged @TimesUpPRS. TimesUpPRS has also garnered industry and private sponsorship, inspired DEI programming, and collaborated with multiple other organizations. CONCLUSIONS: In 2 years, TimesUpPRS has generated 350+ posts and reached 10,000+ accounts. Content highlighted figures of diverse identities and cultivated high, positive engagement. Now with 20 content creators, TimesUpPRS will continue increasing content, expanding its audience, and fostering impactful discussion that helps shift the existing culture to one of inclusivity and equity.

RESUMO

INTRODUCTION: Online patient education materials (PEMs) often exceed the recommended 6th grade reading level. This can negatively affect transmasculine patients' understanding of treatment plans, increasing barriers to care and worsening health outcomes and patient satisfaction. This study assessed the readability of online English and Spanish PEMs regarding phalloplasty and urethroplasty. METHODS: The English and Spanish terms for phalloplasty and urethroplasty were queried on Google. The first fifty results were grouped into institutional (government, medical school, teaching hospital), noninstitutional (private practice, news channel, blog, etc.), and academic (journal articles, book chapters) categories. Readability scores were generated using the Simple Measure of Gobbledygook and Spanish Simple Measure of Gobbledygook scales. RESULTS: All PEMs exceeded recommended reading levels. For both procedures, English PEMs had an average reading level approximately of a university sophomore and Spanish PEMs had an average reading level approximately of a high school junior. For both procedures, English PEMs were harder to read than Spanish PEMs overall (P < 0.001) and when compared across the three categories between the two languages (P < 0.001). For Spanish urethroplasty PEMs, noninstitutional PEMs were more difficult to read than institutional PEMs (P < 0.05). CONCLUSIONS: Online information for phalloplasty and urethroplasty should be revised and/or standardized materials should be created by trans-affirming health-care providers and national organizations in order to more fully educate the public and prospective patients prior to intervention. A well-informed patient population will improve patient decision-making and surgeon-patient communication, ultimately leading to better health outcomes.

RESUMO

BACKGROUND: Olive oil consumption may reduce breast cancer risk, but it is unclear whether olive oil is beneficial for breast cancer prevention in populations outside of Mediterranean regions, namely in the U.S., where the average consumption of olive oil is low compared with Mediterranean populations. We examined whether olive oil intake was associated with breast cancer risk in two prospective cohorts of U.S. women. METHODS: We used multivariable-adjusted time-varying Cox proportional hazards models to estimate hazard ratios (HR) and 95% confidence interval (CI) for breast cancer among 71,330 (Nurses' Health Study, 1990-2016) and 93,295 women (Nurses' Health Study II, 1991-2017) who were free of cancer at baseline. Diet was assessed by a validated semi-quantitative food frequency questionnaire every 4 years. RESULTS: During 3,744,068 person-years of follow-up, 9,638 women developed invasive breast cancer. The multivariable-adjusted HR (95% CI) for breast cancer among women who had the highest consumption of olive oil (>1/2 tablespoon/d or >7 g/d) compared with those who never or rarely consumed olive oil, was 1.01 (0.93, 1.09). Higher olive oil consumption was not associated with any subtype of breast cancer. CONCLUSION: We did not observe an association between higher olive oil intake and breast cancer risk in two large prospective cohorts of U.S. women, whose average olive oil consumption was low. Prospective studies are needed to confirm these findings and to further investigate whether different varieties of olive oil (e.g., virgin and extra virgin olive oil) may play a role in breast cancer risk.
