DXA Scan Variants in Transgender Patients.

Transgender and gender non-conforming (TGNC) individuals face numerous barriers to healthcare, which contribute to many health disparities. TGNC persons may choose gender-affirming therapies with surgery and/or hormone replacement therapy (HRT) to manage gender incongruence. Despite the expanding use of HRT, the long-term outcomes on bone health and metabolism, are still relatively unknown in the TGNC population. In 2019, the International Society of Clinical Densitometry (ISCD) released an official position statement on the appropriate use of dual energy x-ray absorptiometry (DXA) to measure bone density in the TGNC population. In this study, we reviewed which "sex" is currently utilized among providers when performing DXA scans to calculate T- and Z-scores for TGNC persons and how this compares to the positions published by the ISCD. A retrospective analysis was performed utilizing HERON queries and subsequent chart review. HERON is a type of Informatics for Integrating Biology and the Bedside software that was utilized to find sets of patients of interest from electronic medical record data while preserving patient privacy through a query interface tool. Project specific sets including patient demographics, medications, gonadectomy, and DXA scan information was created in HERON to make this highly detailed data of specific patients available to the investigators on the platform, as reviewed and retrieved by the Institutional Review Board. The qualitative DXA data obtained from chart review was determined as "correct" or "incorrect" based on positions provided from the ISCD. 10 DXA scans that met inclusion criteria were obtained between 9 TGNC patients. In total, 18 T-scores and Z-scores of the 10 DXAs were reviewed and scored. Based on ISCD positions, 67% of the T-score and Z-scores were calculated incorrectly; using the erroneous "sex" based standard to compare scores. Like DXA scans, many current healthcare standards and protocols are based on a patient's sex or gender, which may cause confusion amongst healthcare personnel who have not received proper training regarding the TGNC population. In this study, 67% of T-scores and Z-scores were calculated incorrectly based on ISCD recommendations. An additional prospective research design is required to determine the consequences of incorrectly calculated DXA scans for TGNC patients. Furthermore, future research is needed to determine HRT's effects on bone mineral density in the TGNC population in the United States.

Bone Health in the Transgender Population.

¼ Transgender women are more susceptible to low bone mineral density (BMD) before initiating gender-affirming hormone therapy (GAHT), and while bone density initially improves with GAHT, it gradually declines while still remaining above baseline. Transgender women older than 50 years have a comparable fracture risk as age-matched cisgender women. Transgender men typically have normal or increased BMD before initiating and while receiving GAHT and are not at increased risk of fractures.¼ Transgender youth who receive puberty-blocking medications experience either no change or a slight decrease in BMD that returns to baseline after initiating GAHT.¼ It is important to abide by the International Society for Clinical Densitometry guidelines whenever ordering, performing, or reading a BMD scan for a gender-diverse patient.¼ There are no specific guidelines concerning vitamin D and calcium supplementation or the use of bisphosphonates in the transgender population, so the current recommendation is to abide by the guidelines for cisgender individuals.

Characteristics, staging and outcomes of differentiated thyroid cancer in patients with and without Graves' disease.

Background: The incidence of thyroid cancer has increased over the last three decades with studies showing incidence of thyroid cancer is higher among patients with Graves' Disease (GD) when compared to Toxic multinodular goiter.1 We conducted a retrospective study to further investigate characteristics and outcomes in patients with thyroid cancer and GD. Methods: We retrospectively reviewed 62 patients with a diagnosis of Differentiated Thyroid Cancer (DTC). We compared age at diagnosis, type, size of tumor, radioactive iodine (RAI) use, and DTC recurrence amongst patients with GD, non-GD patients. We used Chi-square to test for independence among categorical variables at a nominal level of 0.05; comparison was based on t-test. Results: Out of 62 patients, 29 patients had GD and DTC (47%). 94% had papillary thyroid cancer. Patients with GD were diagnosed with DTC at a younger age (mean 46 years) in comparison to patients without GD (mean 53 years). There was no difference in the type of DTC. Patients with GD had significantly smaller tumor size (mean size 1.035 cm; p value = 0.002), more Stage 1 and 2 compared to patients without GD (p-value = 0.009). Both groups of patients had similar rates of recurrence on follow up and RAI use. Conclusion: We found patients with GD had smaller tumor size, early-stage DTC when compared to patients without GD and potentially favorable prognosis. More data is needed to understand whether this is due to pathogenesis like Graves antibodies promoting tumor formation or merely earlier detection of DTC in GD.

Romosozumab used to treat a patient with cystic fibrosis-related osteoporosis.

Bone disease is a known complication of cystic fibrosis (CF). To date, there have been no reports on the effectiveness of romosozumab, monoclonal antibody to sclerostin, to treat CF-related bone disease. We report a case of a 46-year-old premenopausal female with CF-related bone disease and multiple fractures who was treated with romosozumab. After one year of therapy with romosozumab, the patient tolerated therapy and bone mineral density (BMD) significantly improved. Of the currently available anti-resorptive or anabolic osteoporosis medications, only bisphosphonates have been studied in individuals with CF. This report highlights that romosozumab may be an effective alternative treatment modality in selected patients with CF at high risk for fractures. Further studies are warranted to evaluate the efficacy and safety profile of romosozumab in people with CF.

CGM patterns in adults with cystic fibrosis-related diabetes before and after elexacaftor-tezacaftor-ivacaftor therapy.

Cystic fibrosis-related diabetes (CFRD) is a common complication of cystic fibrosis that is associated with worse outcomes and higher mortality rates. CF transmembrane conductance regulator gene (CFTR) modulators have shown favorable effects on lung function, pulmonary exacerbations, and nutrition status. However, data regarding effects of CFTR modulators on glycemic control among those with CFRD is lacking. In this retrospective study, CGM data was analyzed to determine effect of elexacaftortezacaftor- ivacaftor therapy (ETI), a CFTR modulator, on glucose control among patients with CFRD. No difference was seen in glucose patterns after 3- and 6- months of starting ETI.

Evaluation of Financial Conflicts of Interest Among Physician-Authors of American College of Rheumatology Clinical Practice Guidelines.

OBJECTIVE: Clinical practice guidelines (CPGs) underpin patient care, and ideally authors of these guidelines would be free from outside influence. However, it has been shown many times that authors of professional society CPGs receive large sums of money from industry drug companies, creating financial conflicts of interest. This study investigated industry payments catalogued in the Open Payments Database (OPD) that have been received by authors of the American College of Rheumatology (ACR) CPGs. METHODS: Guidelines on the ACR web site that were published during or after August 2014 were used to retrieve the list of authors. All general, research, associated research, and ownership payments reported on the OPD between the date of publication of the CPG and 12 months prior were extracted in a parallel and blinded manner by 2 investigators. RESULTS: Of the 89 US-based physician-authors from the 5 ACR CPGs identified within the study timeframe, 56 (62.9%) had received at least 1 payment according to OPD records. These 56 authors had received a median of $522 (interquartile range $119-2,500), which, combined, was a total of $9,728,751. Nineteen authors had received at least 1 industry payment relevant to the CPG recommendations, for a median amount of $748 and a total of $1,961,362 in relevant payments. Of the total relevant payments received, a significant proportion was undisclosed (for ACR CPGs during or after August 2014, undisclosed payments were $699,561, or 35.7% of the total). CONCLUSION: Fewer than one-half of the US-based physician-authors of ACR CPGs during or after August 2014 had received guideline-relevant industry payments. Nonetheless, a substantial proportion of the money received was not disclosed. Conflict of interest disclosure is a bare minimum requirement, and more permanent solutions may include divestiture or inclusion of more nonconflicted authors.
