Eating disorder symptoms among transgender and gender diverse youth.

Compared to cisgender peers, transgender and gender diverse (TGD) youth and adults report elevated eating disorder (ED) symptoms likely related to gender dysphoria and attempts to modify their bodies accordingly. Less is known about the impact on gender-affirming care and ED symptoms. This study aimed to expand on extant research and describe ED symptoms in TGD youth seeking gender-affirming care while exploring potential associations between gender-affirming hormone use and ED symptoms. A total of 251 TGD youth completed the Eating Disorders Examination-Questionnaire (EDE-Q) as part of routine clinical care. ANCOVAs and negative binomial regressions examined differences in ED symptoms among transgender females (identifying as female but assigned male at birth) and transgender males (identifying as male but assigned female at birth). ED severity was not significantly different among transgender females versus transgender males, (p = .09), or associated with gender-affirming hormone use (p = .07). Transgender females receiving gender-affirming hormones reported a greater proportion of objective binge eating episodes compared to those who were not (p = .03). Over a quarter of TGD youth reported engagement in ED behaviors suggesting assessment and intervention related to ED behaviors among TGD youth is imperative since adolescence is a particularly vulnerable period for adolescents and engagement in ED behaviors could lead to full ED development and medical risk.

Adaptations of cognitive remediation therapy for adolescents with anorexia nervosa for delivery via telehealth.

OBJECTIVE: The COVID-19 pandemic hastened a transition to treatment delivery via telehealth. While barriers still exist, the increased uptake of telehealth has the potential to increase access to mental health treatment for all diagnoses, including eating disorders. Delivery of evidence-based treatment as well as adjunctive treatments, including those that are hard to find in-person, have been modified to virtual format to increase accessibility and allow for continuity of care for adolescents with anorexia nervosa. METHOD: We describe how to modify and deliver Cognitive Remediation Therapy for youth with anorexia nervosa (CRT-AN) via a telehealth platform. Preliminary and practical guidance for best practice for both group and individual delivery is established. RESULTS: With minimal modifications, CRT-AN can be delivered via telehealth for both individual and group delivery. More disengagement in group delivery was noted; however, overall application of the treatment via a remote platform was observed. DISCUSSION: As more treatment moves to a telehealth format, highlighting how an adjunctive treatment like CRT-AN can combined with other treatments in a telehealth format has the potential to increase research in its implementation and furthermore increase its dissemination. PUBLIC SIGNIFICANCE: Cognitive Remediation Therapy for Anorexia Nervosa (CRT-AN) requires significant manipulation of materials and supplementary human guidance. Suggestions for how to modify CRT-AN for remote delivery via telehealth are provided. Modifications grew out of immediate changes made during the beginning of the COVID-19 pandemic and can be used to inform changes therapists and programs can make to continue to or begin to use CRT-AN in a remote fashion.

Modifiable factors associated with mental health symptoms in siblings of adolescents with anorexia nervosa.

PURPOSE: Research demonstrates that anorexia nervosa (AN) takes a significant toll on affected families, yet the well-being of siblings has been largely overlooked. This study examines mental health symptoms in siblings of adolescents with AN and seeks to identify modifiable factors associated with well-being. METHOD: Participants included 34 siblings (aged 11-19) of adolescents with AN and 47 age and sex matched controls. Participants and their caregivers completed assessments of anxiety, depression, internalizing and externalizing problems, and parentification. Siblings of adolescents with AN also completed the Sibling Perception Questionnaire, an assessment of perceptions and attitudes about AN. RESULTS: Analyses indicated that siblings of adolescents with AN reported greater anxiety and parentification than controls. On caregiver reports of participants' internalizing and externalizing symptoms, no significant differences were found across groups. In siblings of adolescents with AN, females were more vulnerable to anxiety, depression, and negative attitudes and perceptions about AN than males. Perceived negative interpersonal interactions, specific to having a brother or sister with AN, were associated with greater anxiety and depression among AN siblings. CONCLUSION: Findings from this pilot study suggest that siblings of adolescents with AN are vulnerable to anxiety and parentification behaviors. Negative interpersonal interactions specific to having a brother or sister with AN may perpetuate risk for poorer well-being. Caregivers may not be attuned to these struggles, highlighting the importance of provider and family education about sibling vulnerabilities. Therapeutic interventions that target siblings of adolescents with AN are also indicated. LEVEL OF EVIDENCE: Level III, case-control analytic study.

Caregiver burden and illness perceptions in caregivers of medically hospitalized youth with anorexia nervosa.

Caregiver burden is common in caregivers of youth with anorexia nervosa (AN) and could impede the successful implementation of family-based therapy (FBT). Thus, it is important to better understand mechanisms by which caregiver burden is developed and maintained. This study aimed to examine the relation between caregiver illness perceptions about AN, symptom severity indicators, and caregiver burden in a sample of medically hospitalized youth with AN. Fifty-one youth with AN (N = 34) or Atypical AN (AAN; N = 17; mean age = 14.85, SD = 1.41; 76% female) and their primary caregivers (N = 47 mothers and N = 4 fathers) completed self-report questionnaires at hospital admission. Collected data included caregiver and youth illness perceptions about AN, caregiver burden, and youth self-reports of psychological symptoms. Physiological data regarding symptom severity included admitting percent of expected body weight (%EBW) and minimum heart rate during admission. Findings indicated that caregiver beliefs about negative consequences of AN were associated with caregiver burden, independent of youth age, sex, illness duration, and diagnosis. Youth reports of symptom severity, %EBW, and low heart rate were not associated with increased caregiver burden. Findings suggest that the subjective experience of having a youth with AN are a greater determinant of caregiver burden than objective indicators of illness severity. Further, these findings provide support for the FBT clinician to strike a balance between providing information about the potential consequences of AN, while instilling hope for recovery and bolstering parent self-efficacy.

Triclosan (TCS) and triclocarban (TCC) induce systemic toxic effects in a model organism the nematode Caenorhabditis elegans.

The broad application of triclosan (TCS) and triclocarban (TCC) as antimicrobials in household and personal care products has led to the concerns regarding their human health risk and environmental impact. Although many studies have examined the toxicological effects of these compounds to a wide range of aquatic organisms from algae to fish, their potential toxicity to an important model organism the nematode Caenorhabditis elegans has never been systematically investigated. Here we assessed the toxicological effects of TCS and TCC in C. elegans using endpoints from organismal to molecular levels, including lethality, reproduction, lifespan, hatching, germline toxicity, and oxidative stress. L4 stage or young adult worms were exposed to TCS or TCC and examined using above-mentioned endpoints. Both TCS and TCC showed acute toxicity to C. elegans, with 24-h LC50s of 3.65 (95% CI: 3.15, 4.3) mg/L and 0.91 (95% CI: 0.47, 1.53) mg/L, respectively. TCS at 0.1-2 mg/L and TCC at 0.01-0.5 mg/L, respectively, induced concentration dependent reduction in the worm's reproduction, lifespan, and delay in hatching. Using a DAF-16:GFP transgenic strain, we found both compounds induced oxidative stress in the worm, indicated by the relocalization of DAF-16:GFP from cytoplasm to the nucleus upon exposure. Germline toxicity of the two compounds was also demonstrated using a xol-1:GFP transgenic strain. These findings suggest that TCS and TCC induce systemic toxic effects in C. elegans. Further studies are needed to elucidate the potential mechanisms of toxicity of these antimicrobials in the model organism, especially their potential endocrine disruption effects.
