An increasing number of palliative care educational programs strive to meet the workforce need for palliative care clinicians. This growth necessitates development of robust quality standards. The ...purpose of this Delphi consensus process was to describe high-quality postlicensure interprofessional palliative care education programs. The steering committee, composed of 6 faculty with experience implementing interprofessional palliative care educational programs, developed initial characteristics, definitions, and subcategories, which were refined through a series of 3 iterative Delphi surveys and a public presentation at a national palliative care meeting. More than 50 palliative care clinicians and educators representing multiple professions were invited to participate in the Delphi surveys; 20 completed round 1, 23 completed round 2, and 15 participants completed round 3. The final consensus included 6 characteristics with definitions, and both required and recommended subcategories for each characteristic. Identified characteristics include competencies, content, educational strategies, interprofessional focus, evaluation, and systems integration. This initial description of quality for postlicensure interprofessional palliative care education programs may be used by learners to guide program selection, new or existing program faculty for course development or quality improvement, or professional organizations to evaluate program quality in a program certification or quality award initiative.
Endocytosis represents a category of regulated active transport mechanisms. These encompass clathrin-dependent and -independent mechanisms, as well as fluid phase micropinocytosis and ...macropinocytosis, each demonstrating varying degrees of specificity and capacity. Collectively, these mechanisms facilitate the internalization of cargo into cellular vesicles. Pregnancy is one such physiological state during which endocytosis may play critical roles. A successful pregnancy necessitates ongoing communication between maternal and fetal cells at the maternal-fetal interface to ensure immunologic tolerance for the semi-allogenic fetus whilst providing adequate protection against infection from pathogens, such as viruses and bacteria. It also requires transport of nutrients across the maternal-fetal interface, but restriction of potentially harmful chemicals and drugs to allow fetal development. In this context, trogocytosis, a specific form of endocytosis, plays a crucial role in immunological tolerance and infection prevention. Endocytosis is also thought to play a significant role in nutrient and toxin handling at the maternal-fetal interface, though its mechanisms remain less understood. A comprehensive understanding of endocytosis and its mechanisms not only enhances our knowledge of maternal-fetal interactions but is also essential for identifying the pathogenesis of pregnancy pathologies and providing new avenues for therapeutic intervention.Endocytosis represents a category of regulated active transport mechanisms.

Objective: Levels of estrogen, androgen, and prolactin have been related to risk of postmenopausal breast cancer. However, the determinants of these hormone concentrations are not established. The ...purpose of this study was to examine correlates of endogenous sex hormones.
Research Methods and Procedures: Associations among adiposity, physical activity, and diet and concentrations of estradiol, free estradiol, estrone, testosterone, free testosterone, sex hormone‐binding globulin (SHBG), androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and prolactin were evaluated in 267 postmenopausal women randomly selected from the Women's Health Initiative Dietary Modification Trial.
Results: In multiple regression analyses on log‐transformed hormones, BMI was positively associated with estrone (β = 0.031, p < 0.001), estradiol (β = 0.048, p < 0.001), free estradiol (β = 0.062, p < 0.001), free testosterone (β = 0.017, p = 0.02), and prolactin (β = 0.012, p = 0.02) and negatively associated with SHBG (β = −0.02, p = 0.001). Total physical activity (metabolic equivalent tasks per week) was negatively associated with concentrations of estrone, estradiol, and androstenedione (β = −0.006, −0.007, and −0.005, respectively, all p ≤ 0.05). Using a composite variable of BMI and physical activity dichotomized by median values, women with high BMI/low physical activity had a mean estrone concentration of 28.8 pg/mL, compared with 24.1, 19.9, and 18.4 pg/mL for women with high BMI/high physical activity, low BMI/low physical activity, and low BMI/high physical activity, respectively (p trend < 0.001). Similar trends were observed for estradiol and free estradiol and, in inverse, for SHBG.
Discussion: These associations may, in part, explain the positive associations between overweight/obesity and a sedentary lifestyle on breast cancer risk.
