Opinion & Special Article: Community Approach Toward Inclusion of Sex and Gender Diversity in Graduate Neurology Education.

Sex and gender diverse (SGD) neurology trainees include transgender, nonbinary, and intersex people. There has been historical exclusion of SGD trainees from participating in clinical care, medical research, and academic training programs. Therefore, neurology educators have unique opportunities to support SGD trainees and colleagues, but may lack the education to appropriately do so. Training programs and professional organizations can collaborate to create safe pathways for SGD trainees to disclose their identities in professional settings. Referral to community support and resources is important for SGD trainees considering professional disclosure. Educators should address the challenges and discrimination unique to SGD graduate trainees in neurology, such as lack of inclusion, affirming environments, supportive policies, and medical accommodations. Faculty training on sensitivity, bias, and bystander effects should be ongoing among institutions. Topics regarding sex and gender diversity are lacking in graduate medical education. Educational curricula often use outdated terminology or binary paradigms to teach about sex and gender. Health care training inequities may cause downstream harm to SGD patients; therefore, training curricula that are reflective of an accurate and affirming understanding of sex and gender may mitigate the potential for inequities. This article provides recommendations to support SGD neurology trainees and to incorporate specific training on sex and gender diversity in academic neurology curricula. Such support is critical to the career success and development of SGD neurology trainees.

Guidelines for research with transgender, gender diverse, and intersex individuals with eating disorders: recommendations from trans and intersex researchers.

Further research is urgently needed to address the disproportionately high rates of eating disorders (EDs) among transgender, gender diverse, and intersex (TGDI) individuals in comparison to cisgender, endosex (non-intersex) populations. As TGDI advocates, academics, and clinicians with lived/living experience with EDs, we propose a set of recommendations to guide ethical research specifically about EDs and disordered eating behaviors in TGDI populations. The guidelines included here aim to educate non-TGDI researchers and support TGDI researchers seeking to carry out such research. Considerations for study design, planning, data collection, and dissemination are included.

Inaccessibility of care and inequitable conceptions of suffering: a collective response to the construction of "terminal" anorexia nervosa.

Informed by our lived experiences with eating disorders, our work providing direct support to communities underserved by existing healthcare structures, and our commitment to social justice, we are deeply troubled by several aspects of the proposed characteristics for "terminal" anorexia nervosa outlined by Gaudiani et al. in Journal of Eating Disorders (10:23, 2022). We have identified two substantial areas of concern in the proposed characteristics provided by Gaudiani et al. and the subsequent publication by Yager et al. (10:123, 2022). First, the original article and the subsequent publication fail to adequately address the widespread inaccessibility of eating disorder treatment, the lack of parameters for what constitutes "high quality care", and the prevalence of trauma experienced in treatment settings for those who do access treatment. Second, the characteristics proposed for "terminal" anorexia nervosa are constructed largely based on subjective and inconsistent valuations of suffering which build on and contribute to harmful and inaccurate eating disorder stereotypes. Overall, we believe these proposed characteristics in their current form stand to detract from, rather than assist, the ability of patients and providers to make informed, compassionate, and patient-centered decisions about safety and autonomy both for individuals with enduring eating disorders and for individuals with more recently diagnosed eating disorders.

Community Engagement Model to Match Psychosocial Health Needs.

The purpose of the current study was to develop a model from community engagement (CE) process data to guide future CE for a focused health problem. Community-based participatory research was used to engage older adults affected by cancer and their family caregivers in eight cancer clusters in one northeastern U.S. state. CE was focused on informing participants about a national telephone helpline offering psychosocial cancer services. A purposeful sample by settings in the cancer clusters yielded an estimated 200,500 individuals who participated in information sessions, health fairs, sporting events, and the media (i.e., print, radio, or television). A general inductive approach was used to analyze CE data and resulted in a four-phase model that health professionals consider in initiating CE. Strategies are discussed for resolving two roadblocks that were identified. This model serves as a guide to standardize CE that informs a community about available services to address a focused health problem. [Res Gerontol Nurs. 2018; 11(6):293-305.].

Caregiver and health care provider preferences of nutritional support in a hematopoietic stem cell transplant unit.

BACKGROUND: Many pediatric oncology patients undergoing hematopoietic stem cell transplantation (HSCT) require nutritional support (NS) because of their inability to consume adequate caloric intake enough calories orally. Although NS can be provided either enteraly (EN) or parenteraly (PN), EN is the preferred method of NS as long as if the gastrointestinal tract is functioning. In this qualitative study, we determined the type of NS preferences and the reservations of caregivers of pediatric HSCT patients undergoing hematopoietic stem cell transplantation (HSCT) as well as those of health care (HC) providers working on the HSCT unit. PROCEDURES: A survey was developed and completed anonymously by HC providers and caregivers. The hypothesis was that HC providers and caregivers would prefer PN because it is convenient to use in patients who already have a central line in place. RESULTS: Most caregivers preferred PN to EN, while most HC providers preferred EN to PN. The barrier between EN initiation and caregivers' approval was the caregivers' perception that EN was invasive and painful, most common obstacle for initiation of EN among caregivers was that it hurts/is invasive, while the barrier with HC providers was vomiting and/abdominal pain associated with EN. CONCLUSIONS: If caregivers were better educated about NS and the advantages/disadvantages of the different forms of NS, their preferences may change. There have been policy changes at St. Jude have been implemented since this study, and an outpatient dietitian now provides education to caregivers about NS during the pre-evaluation for HSCT.

Mutagenicity of ochratoxin A and its hydroquinone metabolite in the SupF gene of the mutation reporter plasmid Ps189.

Ochratoxin A (OTA) is a mycotoxin that enhances renal tumor formation in the outer medulla of male rat kidney. Direct DNA damage and subsequent mutagenicity may contribute to these processes. In this study we have determined whether OTA in the absence or presence of activated rat liver microsomes (RLM) or redox-active transition metals (Fe(III) or Cu(II)) causes promutagenic DNA damage in the supF gene of the mutation reporter plasmid pS189 replicating in human Ad293 cells. In addition, we have assessed the mutagenicity of the hydroquinone metabolite (OTHQ) of OTA in the absence or presence of cysteine without added cofactors. Our results show that oxidation of OTA, either by RLM or by transition metal ions, activates OTA to a directly genotoxic mutagen(s). The Fe(III)/OTA system was the most potent mutagen in our experimental system, causing a 32-fold increase in mutant fraction (MF) above the spontaneous control MF. The Cu(II)/OTA system caused a 9-fold increase in MF, while a 6-10-fold increase in MF was observed for OTA in the presence of RLM. The OTHQ metabolite is also mutagenic, especially in the presence of cysteine, in which a 6-fold increase in MF was observed. Our data provide further insight into OTA bioactivation that may account for its in vivo mutagenicity in male rat kidney.

Detection and characterization of a glutathione conjugate of ochratoxin A.

The ability of the carcinogenic mycotoxin ochratoxin A (OTA) to react with reduced glutathione (GSH) has been assessed using electrospray ionization (ES)-MS techniques. On the basis of the assumption that OTA undergoes biotransformation into the reactive quinone species OTQ (6), a synthetic sample of the reduced form of OTQ (6), hydroquinone OTHQ (5), was prepared and photoreacted with 6 M equiv of GSH to yield an authentic sample of the conjugate 8 that was definitively identified by mass spectrometry, UV-vis spectroscopy and NMR. With the authentic sample of 8 in hand, it was demonstrated that the same conjugate is produced from reaction of 100 microM OTA (1) in the presence of 5 mM GSH following incubation for 1 h with either horseradish peroxidase (HRP)/H(2)O(2), rat liver microsomes (RLM)/NADPH or free Fe(II). In each of these oxidative systems the conjugate 8 was generated in less than 1% yield and the parent OTA molecule is poorly metabolized. Comparison of the peak area ratio of the conjugate 8 to that for the hydroxyOTA metabolite from the RLM/NADPH system implied that the conjugate was produced at a rate of approximately 1-3 pmol min(-)(1) (mg of protein)(-)(1). These studies are the first to demonstrate that OTA undergoes biotransformation to a reactive intermediate [OTQ (6)] that covalently reacts with GSH to yield the conjugate 8. The biological implications of the reactivity of OTA toward GSH are discussed.
