Priorities for efficacy trials of gender-affirming hormone therapy with estrogen: collaborative design and results of a community survey.

PURPOSE: Treatment guidelines for gender-affirming hormone therapy with estrogen (GAHT-E) recommend specific dosing regimens based on limited data. Well-controlled efficacy trials are essential to tailoring treatment to patient goals as the guidelines recommend. The goal of this study was to take a foundational step toward designing community-centered effectiveness trials for gender-diverse individuals seeking GAHT-E. METHODS: Our team developed a cross-sectional survey based on broad clinical experience and consultation with our community advisory board. The survey included 60 items covering demographics, transition history, goals and priorities for treatment, indicators of treatment success, sexual function goals, and future research priorities. The survey was distributed during the summer of 2021, primarily through social networks designed for gender-expansive individuals seeking treatment with estrogen. RESULTS: A total of 1270 individuals completed the survey. Overall treatment goals most frequently rated "extremely important" or "very important" were the following: (1) improved satisfaction with life (81%), (2) appearing more feminine (80%), (3) appearing less masculine (77%), (4) improved mental health (76%), and (5) being seen as your true gender by others (75%). The three body characteristics most frequently rated "highest priority" or "high priority" among changes were the following: (1) facial hair (85%), (2) breast shape or size (84%), and (3) body shape (80%). The highest-rated research priority was comparing feminization with different routes of estrogen administration. CONCLUSION: The goals and experiences of individuals seeking GAHT-E are diverse. Future clinical trials of GAHT-E should be grounded in the needs and priorities of community stakeholders.

Ethics of organ procurement from the unrepresented patient population.

The shortage of organs for transplantation by its nature prompts ethical dilemmas. For example, although there is an imperative to save human life and reduce suffering by maximising the supply of vital organs, there is an equally important obligation to ensure that the process by which we increase the supply respects the rights of all stakeholders. In a relatively unexamined practice in the USA, organs are procured from unrepresented decedents without their express consent. Unrepresented decedents have no known healthcare wishes or advance care planning document; they also lack a surrogate. The Revised Uniform Anatomical Gift Act (RUAGA) of 2006 sends a mixed message about the procurement of organs from this patient population and there are hospitals that authorise donation. In addition, in adopting the RUAGA, some states included provisions that clearly allow organ procurement from unrepresented decedents. An important unanswered question is whether this practice meets the canons of ethical permissibility. The current Brief Report presents two principled approaches to the topic as a way of highlighting some of the complexities involved. Concluding remarks offer suggestions for future research and discussion.

Depression in Nonclassical Hypogonadism in Young Men.

The specific objective of this study was to test the clinically derived hypothesis associating a high prevalence of depression in young men with nonclassical hypogonadism. We studied the entire population of men aged 18 to 40 years who had an outpatient visit at an academic health system in the years 2013 to 2015. The study group comprised 186 patients with a diagnosis of eugonadotropic hypogonadism and a testosterone value below 10.4 nmol/L with no apparent cause. We compared their demographic factors, other diagnoses, and treatments with those of (i) the entire population, (ii) a matched population of 930 controls, and (iii) 404 controls with normal testosterone determinations, and no hypogonadism diagnosis. Depression, defined as either an International Classification of Diseases, Ninth Revision (ICD-9) diagnosis or treatment with an antidepressant medication, was found in 22.6% of cases vs 6.6% of population controls [P < 0.001; OR: 1.13 (1.09 to 1.17); 95% CI]. Obesity was also higher in the cases (P < 0.001). The matched controls had a depression rate of 13.4% compared with the case rate of 22.6% [P < 0.002; OR 1.14 (1.08 to 1.17)]. Controls with normal testosterone determinations had a depression rate of 16.8% [P = 0.121; OR: 1.04 (0.96 to 1.12)], suggesting that clinicians may have ordered a testosterone determination because of symptoms consistent with both depression and hypogonadism. The high incidence of depression in nonclassical hypogonadism in young men, although only associative, supports a depression evaluation and treatment as appropriate as well as investigation of the proximate causes of this form of hypogonadism.

Multifactorial hypercalcemia and literature review on primary hyperparathyroidism associated with lymphoma.

The most common cause of hypercalcemia in hospitalized patients is malignancy. Primary hyperparathyroidism most commonly causes hypercalcemia in the outpatient setting. These two account for over 90% of all cases of hypercalcemia. Hypercalcemia can be divided into PTH-mediated and PTH-independent variants. Primary hyperparathyroidism, familial hypocalciuric hypercalcemia, familial hyperparathyroidism, and secondary hyperparathyroidism are PTH mediated. The most common PTH-independent type of hypercalcemia is malignancy related. Several mechanisms lead to hypercalcemia in malignancy-direct osteolysis by metastatic disease or, more commonly, production of humoral factors by the primary tumor also known as humoral hypercalcemia of malignancy that accounts for about 80% of malignancy-related hypercalcemia. The majority of HHM is caused by tumor-produced parathyroid hormone-related protein and less frequently production of 1,25-dihydroxyvitamin D or parathyroid hormone by the tumor. We report the rare case of a patient with hypercalcemia and diagnosed primary hyperparathyroidism. The patient had persistent hypercalcemia after surgical removal of parathyroid adenoma with recorded significant decrease in PTH level. After continued investigation it was found that the patient also had elevated 1,25-dihydroxyvitamin D and further studies confirmed a large spleen mass that was later confirmed to be a lymphoma. This is a rare example of two concomitant causes of hypercalcemia requiring therapy.

A pregnant dilemma: primary hyperparathyroidism due to parathyromatosis in pregnancy.

OBJECTIVE: To describe an exceedingly rare case of parathyromatosis in pregnancy and the limited medical treatment options available for such cases that are refractory to surgery. METHODS: Case presentation and description of clinical course with brief review of the literature. RESULTS: A 21-year-old woman with a history of 3.5 gland parathyroidectomy presented with severe hyperemesis during her first trimester of pregnancy and was found to have primary hyperparathyroidism attributable to parathyromatosis. We describe the diagnostic and management dilemmas associated with this case, which included localization of the culprit lesions, a technically challenging surgical resection and subsequent medical management with cinacalcet when symptomatic hypercalcemia recurred during the third trimester. To our knowledge, this is only the third report of the successful use of cinacalcet during pregnancy, and the first case report of parathyromatosis presenting during pregnancy. CONCLUSION: Cinacalcet was used safely and effectively during the third trimester of pregnancy to treat symptomatic hypercalcemia due to parathyromatosis.

Variants identified in a GWAS meta-analysis for blood lipids are associated with the lipid response to fenofibrate.

A recent large-scale meta-analysis of genome-wide studies has identified 95 loci, 59 of them novel, as statistically significant predictors of blood lipid traits; we tested whether the same loci explain the observed heterogeneity in response to lipid-lowering therapy with fenofibrate. Using data from the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN, n = 861) we fit linear mixed models with the genetic markers as predictors and high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, total cholesterol, and triglyceride concentrations as outcomes. For all four traits, we analyzed both baseline levels and changes in response to treatment with fenofibrate. For the markers that were significantly associated with fenofibrate response, we fit additional models evaluating potential epistatic interactions. All models were adjusted for age, sex, and study center as fixed effects, and pedigree as a random effect. Statistically significant associations were observed between the rs964184 polymorphism near APOA1 (P-value≤0.0001) and fenofibrate response for HDL and triglycerides. The association was replicated in the Pharmacogenetics of Hypertriglyceridemia in Hispanics study (HyperTG, n = 267). Suggestive associations with fenofibrate response were observed for markers in or near PDE3A, MOSC1, FLJ36070, CETP, the APOE-APOC1-APOC4-APOC2, and CILP2. Finally, we present strong evidence for epistasis (P-value for interaction =  0.0006 in GOLDN, 0.05 in HyperTG) between rs10401969 near CILP2 and rs4420638 in the APOE-APOC1-APOC4-APOC2 cluster with total cholesterol response to fenofibrate. In conclusion, we present evidence linking several novel and biologically relevant genetic polymorphisms to lipid lowering drug response, as well as suggesting novel gene-gene interactions in fenofibrate pharmacogenetics.

Improving communication when seeking informed consent: a randomised controlled study of a computer-based method for providing information to prospective clinical trial participants.

OBJECTIVE: To assess the efficacy, with respect to participant understanding of information, of a computer-based approach to communication about complex, technical issues that commonly arise when seeking informed consent for clinical research trials. DESIGN, SETTING AND PARTICIPANTS: An open, randomised controlled study of 60 patients with diabetes mellitus, aged 27-70 years, recruited between August 2006 and October 2007 from the Department of Diabetes and Endocrinology at the Alfred Hospital and Baker IDI Heart and Diabetes Institute, Melbourne. INTERVENTION: Participants were asked to read information about a mock study via a computer-based presentation (n = 30) or a conventional paper-based information statement (n = 30). The computer-based presentation contained visual aids, including diagrams, video, hyperlinks and quiz pages. MAIN OUTCOME MEASURES: Understanding of information as assessed by quantitative and qualitative means. RESULTS: Assessment scores used to measure level of understanding were significantly higher in the group that completed the computer-based task than the group that completed the paper-based task (82% v 73%; P = 0.005). More participants in the group that completed the computer-based task expressed interest in taking part in the mock study (23 v 17 participants; P = 0.01). Most participants from both groups preferred the idea of a computer-based presentation to the paper-based statement (21 in the computer-based task group, 18 in the paper-based task group). CONCLUSIONS: A computer-based method of providing information may help overcome existing deficiencies in communication about clinical research, and may reduce costs and improve efficiency in recruiting participants for clinical trials.

Polycystic ovarian syndrome: the next cardiovascular dilemma in women?

All known risks for cardiovascular disease are increased in women with polycystic ovary syndrome, which features amenorrhea, hirsutism, and obesity. Epidemiologic studies in these patients and their families have revealed a familial predisposition not only to polycystic ovary syndrome, but also diabetes, hypertension, and cardiovascular disease. The heterogeneity of phenotypes (clinically and biochemically) leads to difficulty in achieving a precise diagnosis, defining a single underlying pathogenesis, and selecting a homogeneous population for much needed prospective studies. The authors believe that while insulin resistance plays and important role in some cases of polycystic ovarian syndrome, it is the overall milieu created by the co-existence of several cardiovascular risk factors in polycystic ovarian syndrome patients which could be an important target for preventative strategies and therapy.

Management of the cardinal features of andropause.

There are several problems facing aging men, especially sexual dysfunction, hypogonadism, and psychologic changes. This constellation of changes is sometimes referred to as "manopause" or "andropause." Unlike the dramatic changes in the hormonal milieu occurring during menopause in women, the age-related changes in reproductive hormones of men are subtle and occur gradually throughout the years of mature life. It has been estimated that circulating testosterone (T) declines longitudinally from age 19 at an average rate of 1% per year. The free or dialyzable fraction of serum T and the bioavailable (the sum of free fraction and loosely bound to albumin fraction) T decline more rapidly with age. Although the essential role of androgens in reproductive tissue development and emergence of secondary sex characteristics is well known, their role in adult sexual function seems to be primarily facultative. The effect of T on the central nervous system extends beyond sexual behavior. T has been shown to alter mood, memory, ability to concentrate, and the overall sense of vigor and well being that may interact with a host of other psychologic changes associated with aging. Disordered erectile function is not generally an endocrine problem but rather vascular, neurologic, and psychogenic in origin. It also may be the first sign of systemic vascular disease. The clinical management of andropause requires an individualized approach. In some men, the main problem may be psychologic, whereas in others, hypogonadism may play an important role. Many with erectile failure, suffer silently regardless of its etiology. In this review, we suggest some practical guidelines for the management of these conditions.

beta-Cell function: a key pathological determinant in polycystic ovary syndrome.

We report data from 60 patients with polycystic ovary syndrome (PCOS) who had undergone assessment of insulin resistance, pancreatic beta-cell function, obesity, and androgen levels to elucidate the complex relationships among these traits. Homeostasis model assessment was used to quantify insulin resistance and beta-cell function. A reference population was derived from the National Health and Nutrition Examination Study (NHANES III, 1988-1994). Indices of insulin resistance, insulin secretion, bioavailable testosterone, and body mass index all exhibited significant pairwise correlations. Multiple regression analysis clarified the phenotypic relationships, demonstrating that insulin resistance and bioavailable testosterone were independent predictors of beta-cell function; beta-cell function and obesity were independent predictors of insulin resistance; and beta-cell function was an independent predictor of bioavailable testosterone. Of note, comparison with normal women from NHANES revealed a significantly stronger relationship between beta-cell function and insulin resistance in PCOS, raising the possibility of an intrinsic defect in beta-cell function whereby increasing insulin resistance leads to a greater insulin response in PCOS than normal. The altered relationship of beta-cell function and insulin resistance coupled with the fact that beta-cell function, not insulin resistance, was a predictor of hyperandrogenemia suggests that beta-cell dysfunction may be a key pathogenic determinant in PCOS.

Peripheral thyroid hormones and response to selective serotonin reuptake inhibitors.

OBJECTIVE: To examine the relation between baseline measurements of thyroid function and response to selective serotonin reuptake inhibitors (SSRIs) and to consider the effect of these antidepressants on thyroid hormone levels. METHODS: Nineteen subjects with major depression, but without a history of thyroid treatment or lithium treatment, were treated openly with either sertraline or fluoxetine in a university- affiliated tertiary care hospital. Hamilton Depression Rating Scale (Ham-D) scores were measured before and after treatment. Clinical Global Impressions (CGI) scores were measured at study end. Thyroid data, consisting of values for thyroid-stimulating hormone (TSH), triiodothyronine (T(3), measured by radioimmunoassay [RIA]), thyroxine (T(4), measured by RIA) and free T(4), were collected before and after treatment. Complete thyroid data were available for 17 subjects. Data were collected during 1997-1999. RESULTS: Baseline TSH correlated strongly with response to treatment as measured by change in Ham-D scores (r = 0.64, p = 0.003). Low TSH values correlated with greater improvement in depressive symptoms. Thyroid hormone levels decreased with treatment, but these decreases did not correlate with clinical improvement. CONCLUSION: Baseline thyroid function, as measured by serum TSH, may predict a patient's response to antidepressant treatment with SSRIs. Optimal thyroid function, beyond simply being within the normal laboratory values, may be necessary for an optimal response to antidepressants.

Erection quality scale: initial scale development and validation.

OBJECTIVES: The Erection Quality Scale (EQS) is a new, self-report measure for assessing the quality of penile erections. It is intended to complement existing diagnostic and outcome measures (eg, International Index of Erectile Function, Sexual Encounter Profile) in both clinical practice and outcomes research in erectile dysfunction (ED). METHODS: The initial phases of development and psychometric validation of the EQS are described. Specifically, qualitative research in patients and healthy men was used to generate relevant constructs. On the basis of the findings from these phases, and recommendations from an expert panel, seven constructs were selected for inclusion. Multiple items with different formats were drafted to measure each of the key constructs. An iterative process of cognitive testing, item revision, and item reduction was used to identify the 15 most appropriate items and their optimal response scales. This version of the scale was tested in a 200-subject discriminant validity study designed to gather data for a psychometric evaluation. Participants were classified into ED-untreated, ED-treated, and healthy control groups to evaluate the discriminant validity of the measure in men with different levels of erectile function. RESULTS: The study results supported a robust single-factor structure, indicating that the EQS provides an overall index of erection quality. An intraclass correlation coefficient of 0.85 denotes adequate test-retest reliability. Furthermore, the EQS correlated well with existing measures and differentiated patients from the three ED classifications, a preliminary indication of discriminant validity. CONCLUSIONS: The findings presented provide evidence of the scale's potential utility for measuring erection quality in future studies.

Epidemiology of erectile dysfunction.

Following the landmark Massachusetts Male Aging Study (MMAS) that provided the first relatively unbiased study of the epidemiology of erectile dysfunction (ED), a number of additional studies were carried out in the U.S. and around the world. The studies vary in quality because they used different definitions of ED, different assessment instruments, different and sometimes biased sources of populations, inadequate response rates to questionnaires and interviews, cultural disparities in willingness to discuss sexual issues, and differing interpretations of the results. Nevertheless, the studies demonstrated similar levels of ED by age and an exponential rise with age. They also generally confirmed the conditions that correlated with ED in the MMAS, namely, diabetes, hypertension, coronary artery disease, prostate cancer therapy, and depression. These were exacerbated by cigarette smoking.

Ethnic differences in insulin sensitivity and beta-cell function in premenopausal or early perimenopausal women without diabetes: the Study of Women's Health Across the Nation (SWAN).

OBJECTIVE: To assess differences in insulin sensitivity and beta-cell function between nondiabetic premenopausal or early perimenopausal non-Hispanic white women and African American, Chinese American, Japanese American, and non-Mexican-American Latino women. RESEARCH DESIGN AND METHODS: Homeostasis model assessments (HOMAs) of insulin sensitivity (HOMA%S) and beta-cell function (HOMA%beta) were used. Stepwise multivariable ethnic-specific ANCOVA models were used to compare HOMA%S and HOMA%beta between non-Hispanic whites and each of the four ethnic groups. RESULTS: HOMA%S was lower in African Americans, Chinese Americans, and Japanese Americans when compared with non-Hispanic white women after correcting for waist circumference, presence of impaired fasting glucose, and site. Significant differences persisted only between African Americans and non-Hispanic whites after inclusion of triglycerides in the model. Triglycerides indirectly corrected for the differences in HOMA%S in the other two groups. There were no differences in HOMA%S between the non-Mexican-American Latinos and the non-Hispanic whites. Japanese Americans and Chinese Americans had lower HOMA%beta than non-Hispanic whites, whereas African Americans had higher HOMA%beta than non-Hispanic whites after correcting for confounders. HOMA%beta was similar between non-Mexican-American Latinos and non-Hispanic whites. CONCLUSIONS: These data suggest that type 2 diabetes prevention strategies for African-American women should initially target decreased insulin sensitivity, whereas strategies for Japanese-American and Chinese-American women may initially need to target both decreased insulin sensitivity and beta-cell function. Previous studies of Mexican-American populations may not apply to non-Mexican-American Latino women.
