Environmental sustainability in gynecologic oncology.

Climate change is a complex, global issue that is impacting human health in various ways, with healthcare being a significant contributor to carbon emissions in the United States. This review discusses the environmental impact of important aspects of gynecologic oncology care, including surgery, anesthesia care, radiology, chemotherapy, and radiation oncology. Operating room energy and material use is highlighted, with a focus on the environmental impact of robotic surgery. The contribution of certain anesthetic gases in increasing greenhouse gas emissions is addressed. Additionally, the environmental impacts of radiologic imaging, chemotherapy, and radiation oncology are also discussed. Despite the complexity of climate change, there are multiple strategies on the individual and institutional level that can help mitigate the environmental impact of gynecologic oncology care. Individual efforts include practicing red bag stewardship, limiting single use-supplies, decreasing the use of potentially deleterious anesthetics, and supporting research into alternative dosing for chemotherapy and radiation which requires less patient travel. Institutional strategies include investing in efficient HVAC systems, utilizing reusable and reprocessed materials and devices, and purchasing renewable energy sources. Both individuals and institutions can advocate with industry and government at all levels for practices and policies that support lower carbon emissions. By recognizing our role in reducing carbon emissions, we can work towards improving the well-being of our patients and the larger community.

Fluconazole-Resistant Candida albicans Vaginal Infections at a Referral Center and Treated With Boric Acid.

OBJECTIVE: The authors investigate the incidence of clinical and mycological resistance of Candida albicans vulvovaginitis (VVC) at the Jefferson Vulvovaginal Health Center. They also review their experience with boric acid in the treatment of fluconazole-resistant VVC. METHODS: The authors conducted a retrospective chart review of all patients with C. albicans VVC diagnosed at the Jefferson Vulvovaginal Health Center between November 2019 and December 2021. Patients with clinically defined fluconazole resistance were identified. Information about demographics, in vitro susceptibility testing, and treatment outcomes with boric acid was obtained. RESULTS: Of 970 patients with vaginal C. albicans isolates, 71 (7.3%) with clinically defined fluconazole-resistant C. albicans infections were identified. Relevant demographics included 45.1% African American, 43.7% aged younger than 30 years, and 43.7% with body mass index less than 25. Of the 71 patients, 58 (81.7%) received vaginal boric acid treatment. The mycological and clinical cure rates were 85.7% and 73.7%, respectively. After successful boric acid treatment and negative yeast cultures, 14.3% of patients had a mycological recurrence within 3 months. Of 31 isolates with antifungal susceptibility testing, 83.9% (26/31) were found to have minimal inhibitory concentration results consistent with fluconazole resistance. CONCLUSIONS: In a tertiary care vulvovaginal health center, fluconazole-resistant Candida albicans VVC is by no means uncommon and usually responds in the short term to treatment with boric acid. However, in the absence of maintenance boric acid, recurrence of culture-positive VVC is likely.

Doula engagement and maternal opioid use disorder (OUD): Experiences of women in OUD recovery during the perinatal period.

BACKGROUND: Pregnant women who have substance use disorders (SUDs) are at increased risk of preterm birth, fetal mortality, and inadequate prenatal care and have higher rates of childhood trauma than their counterparts without SUDs. Doulas have been utilized with other vulnerable populations who experience trauma to increase perinatal healthcare utilization, provide emotional support, and improve birth outcomes. The objective of the current study was to examine, in women with opioid use disorder (OUD), perceptions of working with a doula in the perinatal period. METHODS: Eligible participants were ≥ 18 years old, in OUD treatment, and were pregnant or recently delivered (child ≤ 3 months of age). Semi-structured interviews were used to collect tacit data on the woman's experience working with a doula during the perinatal period. All one-hour interviews were conducted over the phone and transcribed verbatim by a HIPAA compliant transcription service. Transcripts were reviewed independently by 4 coders using open coding procedures, constant comparative method of grounded theory, and inductive thematic analysis. Demographic data and history of childhood trauma information (Adverse Childhood Experiences Tool) were collected with a phone survey prior to the interview. RESULTS: Participants' (N = 23) were 32.5 years of age (4.1 SD), with the majority Caucasian (71.4%), Non-Hispanic (71.4%) and Medicaid recipients (100%). Participants reported a mean of 5.61 (SD=2.93) adverse childhood experiences, indicating a significant trauma burden. Major themes uncovered in the interview transcripts revealed emotional and OUD recovery support provided by the doula and increased maternal health literacy and self-advocacy. The presence of a doula during labor/delivery reduced maternal perceptions of stigma they perceived from their healthcare providers. CONCLUSION: Doula engagement was associated with perceptions of increased emotional support, health literacy and self-advocacy in maternal health among women with OUD, which is significant given this population's trauma histories. This preliminary research has significant implications for improving the health of the mother child dyad affected by maternal OUD.

Genomics Analysis of L-DOPA Exposure in Drosophila sechellia.

Drosophila sechellia is a dietary specialist fruit fly that evolved from a generalist ancestor to specialize on the toxic fruit of Morinda citrifolia This species pair has been the subject of numerous studies where the goal has largely been to determine the genetic basis of adaptations associated with host specialization. Because one of the most striking features of M. citrifolia fruit is the production of toxic volatile compounds that kill insects, most genomic studies in D. sechellia to date have focused on gene expression responses to the toxic compounds in its food. In this study, we aim to identify new genes important for host specialization by profiling gene expression response to 3,4-dihydroxyphenylalanine (L-DOPA). Recent work found it to be highly abundant in M. citrifolia, critical for reproductive success of D. sechellia, and supplementation of diet with the downstream pathway product dopamine can influence toxin resistance phenotypes in related species. Here we used a combination of functional genetics and genomics techniques to identify new genes that are important for D. sechellia ecological adaptation to this new niche. We show that L-DOPA exposure can affect toxin resistance phenotypes, identify genes with plastic responses to L-DOPA exposure, and functionally test an identified candidate gene. We found that knock-down of Esterase 6 (Est6) in a heterologous species alters toxin resistance suggesting Est6 may play an important role in D. sechellia host specialization.
