RESUMEN
Background: A goal of gender-affirming hormone therapy (GAHT) for transgender women is to use estradiol to suppress endogenous production of testosterone. However, the effects of different estradiol regimens and route of administration on testosterone suppression is unknown. This is the first open-label randomized trial comparing different GAHT regimens for optimal estradiol route and dosing. Objective: To evaluate 1 month and 6 months testosterone suppression <50 ng/dL with pulsed (once- or twice-daily sublingual 17-beta estradiol) and continuous (transdermal 17-beta estradiol) GAHT. Methods: This study was conducted at an outpatient adult transgender clinic. Thirty-nine transgender women undergoing initiation of GAHT were randomly assigned to receive either once-daily sublingual, twice-daily sublingual, or transdermal 17-beta estradiol. All participants received spironolactone as an antiandrogen. Doses were titrated at monthly intervals to achieve total testosterone suppression <50 ng/dL. Results: Transdermal 17-beta estradiol resulted in more rapid suppression of total testosterone, lower estrone levels, with no differences in estradiol levels when compared to once-daily and twice-daily sublingual estradiol. Moreover, there was no difference in the mean estradiol dose between the once-daily and twice-daily sublingual 17-beta estradiol group. Conclusion: Continuous exposure with transdermal 17-beta estradiol suppressed testosterone production more effectively and with lower overall estradiol doses relative to once or twice daily sublingual estradiol. Most transgender women achieved cisgender women testosterone levels within 2 months on 1 or 2 0.1 mg/24 hours estradiol patches. Given no difference between once- or twice-daily sublingual estradiol, pulsed 17-beta estradiol likely provides no benefit for testosterone suppression.
RESUMEN
BACKGROUND: Current guidelines for gender-affirming hormone therapy (GAHT) for transgender women are mostly based on clinical experience from experts in the field and treatments used on postmenopausal women. While care is currently provided with the best available evidence, there is a critical gap in knowledge about the safest and most effective estradiol routes of administration for GAHT in transgender women; this statement is supported by the World Professional Association for Transgender Health on their Standards of Care for the Health of Transgender and Gender Diverse People, version 8. Furthermore, the reported rates of cardiometabolic adverse events in transgender women highlight the importance of investigating changes in lipoproteins, glucose, and insulin sensitivity, among other markers while receiving GAHT. OBJECTIVE: This study aims to evaluate the degree of testosterone suppression achieved at 1, 6, and 12 months in treatment-naive transgender women when randomized to GAHT with estradiol and spironolactone as antiandrogens. As a secondary aim, this study will assess the treatment effect on metabolic and coagulation factors from baseline to 6 and 12 months after initiating GAHT. METHODS: This is a prospective pilot, open-label, randomized clinical trial conducted at an adult transgender clinic in a tertiary medical center. The 3 treatment arms include once-daily sublingual 17-ß estradiol, twice-daily sublingual 17-ß estradiol, and transdermal 17-ß estradiol. All participants received spironolactone as an antiandrogen. Transgender women aged 18 to 45 years who are being evaluated for the initiation of GAHT with 17-ß estradiol and did not have a history of coagulopathy, cigarette smoking, liver disease, dyslipidemia requiring treatment, or use of gonadotropin-releasing hormone agonist were eligible to enroll. The main outcome is the total testosterone suppression at 1 and 6 months after the initiation of GAHT, and the secondary outcome is to assess treatment effect in a lipid panel; homeostatic model assessment for insulin resistance; coagulation factors II, IX, and XI; Von Willebrand factor; activated protein C resistance; protein C; and protein S at baseline, 6 months, and 12 months after therapy is initiated. RESULTS: This study was funded in March 2022, and enrollment concluded in August 2022. It was concluded in July 2023, and currently, the results are being analyzed for publication. CONCLUSIONS: The Transgender Estradiol Affirming Therapy (TREAT) study offers a rigorous and reproducible approach to answer important questions regarding GAHT in transgender women, specifically, the most effective 17-ß estradiol regimen to suppress testosterone levels to 50 ng/dL, as currently recommended.

RESUMEN
Diabetes mellitus is one of the most commonly encountered pregnancy complications and is associated with multiple adverse perinatal outcomes. Technology has progressed to address the unique challenges patients face in managing diabetes mellitus in pregnancy. Technology has bolstered diabetes mellitus education with smartphone applications focused on nutrition counseling and carbohydrate intake advice. Continuous glucose monitors and insulin infusion systems have shown benefit by simplifying glycemic monitoring and insulin administration. Improvements in glycemic control and perinatal outcomes have been seen with continuous glucose monitor use when compared with intermittent blood glucose monitoring, and more pregnant people are using insulin pumps instead of multiple daily insulin injections. Hybrid closed-loop systems are emerging and are able to integrate continuous glucose monitoring and insulin pump technologies while maximizing automated features in the nonpregnant population, but these have not been endorsed for use in pregnancy yet. Applying telehealth practices has been associated with high patient satisfaction among those with diabetes mellitus in pregnancy, and leveraging remote patient monitoring through telehealth platforms and short-range wireless technologies can reduce the burden of patient visits. As technology becomes more integrated into routine management of diabetes mellitus in pregnancy, practitioners should emphasize individualized counseling and device selection to ensure patient autonomy and safety.
RESUMEN
The clinical nurse leader (CNL) role has been cited as an effective strategy for improving care at the microsystem level. The purpose of this article is to describe the use of the CNL role in an academic medical center for evaluating pressure ulcer reporting. The Plan-Do-Study-Act cycle was used as the methodological framework for the study. The CNL assessment of pressure ulcers resulted in a 21% to 50% decrease in the number of hospital-acquired pressure ulcers reported in a 3-month time period. The CNL role has potential for improving the validity and reliability of pressure ulcer reporting.

Field tests of four different bait supplements were conducted in City Park, New Orleans, LA. The four bait supplements tested included two different formulations of decayed material, a sports drink, and the combination of an application of an aqueous solution of Summon Preferred Food Source disks with the disk itself. Although all the bait supplements in this study resulted in a slightly greater number of treated stations discovered compared with control stations, only the application of the aqueous solution combined with the disk caused a significant increase in the number of stations discovered by termites. This treatment resulted in a significantly greater rate of discovery of treated stations versus control stations after only 14 d in the field. Termites were able to discover six times as many treated as control stations after 14 d, 9 times as many after 28 d, and 12 times as many after 42 d. These findings provide evidence that the diffusion of an aqueous solution into the soil underneath monitoring stations significantly decreased the length of time required for termites to infest stations.

The feeding preferences of the Formosan subterranean termite, Coptotermes formosanus Shiraki, for commercial lumber Alaska yellow cedar, Chamaecyparis nootkatensis (D. Don) Spach; yellow birch, Betula alleghaniensis Britton; northern red oak, Quercus rubra L.; redwood, Sequoia sempervirers (D. Don) Endl; and spruce (Picea spp.) were examined to determine whether the presence of the lignin-degrading basidiomycete Marasmiellus troyanus (Murrill) Singer could alter the relative preference of termites for these wood species. In paired choice tests with fungus-inoculated sawdust versus control sawdust, termites showed a strong preference for the fungus-inoculated sawdust for all wood species tested, except for Alaska yellow cedar. In a multiple-choice test using sawdust without fungus, termites showed a very strong preference for red oak sawdust over the other three species. In a paired choice test using fungus-inoculated sawdust, termites showed a preference for redwood over red oak sawdust. In a feeding test using autoclaved wood blocks without fungal decay, there was no difference in termite consumption of birch, red oak, or redwood. The relative preference of termites for redwood increased when blocks were decayed by M. troyanus for 3 and 8 wk. These results indicate that chemical modifications due to fungal decay affected the feeding preference of termites for different commercial lumber.
