Purpose: The objective of this study is to determine the prevalence of certain autoimmune diseases in transgender and gender diverse (TGD) youth.

Methods: A multicenter, retrospective analysis was conducted from January 2013 to January 2019 of youth ≤26 years of age with concurrent diagnoses of gender dysphoria (GD) and at least one of the studied autoimmune diseases. Prevalence rates were calculated and compared to previously reported rates.

Objectives: Guidelines for monitoring of medications frequently used in the gender-affirming care of transgender and gender-diverse (TGD) adolescents are based on studies in adults or other medical conditions. In this study, we aimed to investigate commonly screened laboratory measurements in TGD adolescents receiving gender-affirming hormone therapy (GAHT).

Methods: TGD adolescents were recruited from 4 study sites in the United States before beginning GAHT.

Background/objective: Type 1 diabetes (T1D) and myasthenia gravis (MG) are autoimmune conditions that rarely co-occur. Here, we report a child with MG who subsequently developed T1D.

Case Report: An 11-year-old girl with seropositive MG diagnosed at 4 years of age presented with muscle pain, cramps, and weight loss of 3.

Objective: Assess the prevalence of headache in transgender and gender-diverse adolescents, comparing prevalence with and without exposure to gender-affirming hormone therapy.

Background: Transgender and gender-diverse youth are an understudied group in whom we can study the effects of sex steroids on adolescents' development of headache. We hypothesized that transfeminine adolescents treated with estrogen would have higher odds of headache than those not treated, and that transmasculine adolescents treated with testosterone would have lower odds of headache than those not treated.

Article Synopsis
  • - Diabetic ketoacidosis (DKA) is a serious complication of type 1 diabetes that requires careful monitoring, and traditional methods for determining DKA resolution do not include measuring plasma ß-hydroxybutyrate (BOHB).
  • - This study aimed to identify a specific BOHB level to define when DKA is resolved in patients treated with intravenous insulin, analyzing data from 403 patients during a four-year period.
  • - The findings suggest that a BOHB level of less than 1.5 mmol/L is effective in indicating DKA resolution, showing strong sensitivity and specificity when compared to standard clinical criteria.

Biallelic pathogenic variants in , a nuclear gene encoding a subunit of mitochondrial complex I, result in a mitochondrial disorder characterized by varying clinical presentations and severity. Here, we expand the neuroimaging and clinical spectrum of NDUFS8-related disorder. We present three cases from two unrelated families (a girl and two brothers) homozygous for a recurrent pathogenic variant [c.

Article Synopsis
  • Clinicians across various medical fields will likely encounter transgender and gender-diverse (TGD) youth, making it important for them to understand how to affirm these individuals in care.
  • Gender-affirming therapy includes recognizing preferred names and pronouns, and the transition process can vary greatly among patients, potentially involving both medical and nonmedical interventions.
  • Medical treatments for gender transition can affect physical health aspects like growth and fertility, so clinicians should inform patients and families about known risks while collaborating on personalized treatment plans.

Background: There is an emerging understanding that coronavirus disease 2019 (COVID-19) is associated with increased incidence of pneumomediastinum. We aimed to determine its incidence among patients hospitalised with COVID-19 in the United Kingdom and describe factors associated with outcome.

Methods: A structured survey of pneumomediastinum and its incidence was conducted from September 2020 to February 2021.

Background: Equations for estimated glomerular filtration rate (eGFR) based on serum creatinine include terms for sex/gender. For transgender and gender-diverse (TGD) youth, gender-affirming hormone (GAH) treatment may affect serum creatinine and in turn eGFR.

Methods: TGD youth were recruited for this prospective, longitudinal, observational study prior to starting GAH treatment.

Background: Chemotherapy regimens containing glucocorticoids and pegaspargase are associated with hyperglycemia; however, the pattern and underlying risk factors are not well characterized. We determined the pattern of hyperglycemia and associated factors in children with acute lymphoblastic leukemia (ALL) receiving glucocorticoids and pegaspargase during induction.

Methods: Retrospective analysis of patients treated between 2010 and 2020 at a single institution.

Differences in lipoprotein-particle subclasses between men and women start in puberty and narrow after menopause, suggesting a role for sex steroids. In this cross-sectional cohort study, we examined lipoprotein subtype profiles in transmasculine adolescents treated with testosterone. Transmasculine adolescents (n = 17) had lipoprotein profiles that were similar to those of cisgender males (n = 33) and more atherogenic than those of cisgender females (n = 32), with higher concentrations of small low-density lipoprotein (LDL) particles (435 ± 222 nmol/L vs.

Article Synopsis
  • * Researchers analyzed data from 55 TGD youth, finding that those who started GnRHa treatment later in puberty had lower height velocity (HV) compared to those who started earlier, with significant differences noted between Tanner stages of puberty.
  • * Overall, TGD youth on GnRHas showed HV similar to prepubertal children, but those who began treatment in later stages of puberty had decreased HV compared to their prepubertal counterparts, indicating the need for further studies on long-term

Here we present a transgender male adolescent with an androgen receptor-positive serous borderline ovarian tumour in the setting of testosterone treatment for medical gender transition. To our knowledge, this is the second report of borderline tumour in a transgender individual and the first in an adolescent, an age group in which borderline tumours are extremely rare. We discuss the specific considerations of treating ovarian tumours in the transgender male population, the incompletely understood role of androgens in the genesis of ovarian epithelial neoplasia, and an emphasis on assessing cancer risk in transgender patients based on patient anatomy.

Purpose: The purpose of this study was to describe baseline physical and laboratory characteristics of participants in the largest prospective study of transgender and gender-diverse (TGD) youth in the United States.

Methods: Participants were recruited from four clinics which specialize in the care of TGD youth before starting either GnRH analogs for pubertal suppression or gender-affirming hormone treatment. Anthropometric and laboratory measurements were abstracted from the medical chart.

Introduction: Minocycline, a member of the tetracycline class of antibiotics, has been associated with benign thyroid pigmentation but reports of thyroid dysfunction are sparse.

Methods: Cases were selected via an inquiry of the electronic medical records for patients with thyroid dysfunction and the use of a tetracycline antibiotic. Non-autoimmune thyroiditis was defined as abnormally low or suppressed thyroid-stimulating hormone (TSH, <0.

Context: Current guidelines recommend close monitoring of electrolytes in transgender patients using spironolactone given the risk of hyperkalemia from mineralocorticoid antagonism. In patients taking spironolactone for other conditions, the rate of hyperkalemia is low, and the utility of frequent monitoring has been questioned.

Objective: We hypothesized that the rate of hyperkalemia in gender-diverse adolescents taking spironolactone is low and, when present, clinically insignificant.

Background: Cystic Fibrosis Related Diabetes (CFRD) is an increasingly common complication in CF. CFRD introduces an additional complex chronic disease to individuals already attending to demanding treatment regimens. An improved understanding of the reaction to and coping mechanisms surrounding CFRD may facilitate management of CFRD.
