Transgender and gender-diverse (TGD) persons represent a small but growing population in the United States. Accessing inclusive, equitable, and evidence-based healthcare remains a challenge for this patient population. Many TGD persons seek gender-affirming care, including gender-affirming hormonal therapy (GAHT) and gender-affirming surgery (GAS), to help ameliorate the physical and mental aspects of their gender incongruence. Both GAHT and GAS induce clinically important histopathologic and anatomic changes in breast tissue. Consequently, breast care in TGD persons has become an increasingly recognized topic of importance in gender-affirming care. However, there remains a scarce but growing base of literature specifically addressing the unique healthcare needs of breast care in TGD patients. This article will review how to establish trusting patient-provider relationships for TGD patients, gender inclusivity in breast clinics and imaging centers, the influence of GAHT and GAS on breast tissue, breast cancer screening recommendations and barriers, and breast cancer risk and treatment considerations in TGD persons.

Manipulation experiments are a cornerstone of ecological research, but can be logistically challenging to execute-particularly when they are intended to isolate the ecological role of large, vagile species, like birds. Despite indirect evidence that birds are influential in many ecosystems, large-scale, multi-year bird manipulation experiments are rare. When these studies are conducted, they are typically realized with caged or netted exclosures, an approach that can be expensive, risky for wildlife, and difficult to maintain. In cases where caged exclosures are not appropriate, alternate approaches are needed to allow rigorous empirical studies on the ecological role of birds. Here, we present and validate a method for experimentally increasing the abundance and richness of birds at the scale of entire aquatic ecosystems. Unlike bird exclusion, this approach is experimentally tractable, appealing to land managers, and possible to deploy over large spatial scales. We tested the efficacy of our approach for increasing bird abundance and species richness at 16 central California ponds. Based on bird visitation data obtained by summer camera trapping, our approach significantly increased bird species richness and abundance at manipulated ponds compared to control ponds. Attractant treatments mitigated the negative effects of a major drought on bird species richness and generated a near doubling of bird abundance in the presence of attractants. Treatments had no effect on most mammal species, with the exception of ground squirrels, which increased in abundance in the presence of attractants. These results suggest that attractants are effective in increasing bird abundance and richness. We encourage researchers to consider this approach for experimentally isolating the ecological role of birds in aquatic and open terrestrial ecosystems, especially in cases where cost or logistical constraints preclude the use of caged or netted exclosures., Competing Interests: None declared.
