RESUMEN

INTRODUCTION: Advancements in vascularized composite allotransplantation have made hand transplants possible for persons living with upper limb loss. Hand transplantation is not a life-saving procedure, but rather a quality-of-life enhancing procedure; hence the risk of morbidity and mortality must be weighed against improvements in function and appearance. This study explored the decision-making process of patients evaluated for hand transplantation. METHODS/APPROACH: A qualitative case series study using retrospective chart data of evaluations was conducted between January 1, 2011 and February 28, 2020. Notes were extracted and read by three reviewers. Each case was summarized noting similarities and differences. FINDINGS: Nine patients underwent evaluation. Eight were no longer under evaluation and did not receive transplant; one was still undergoing evaluation. Patient motivations for evaluation were dissatisfaction with prostheses or self-image, chronic pain, performing activities of daily living, occupation, burden placed on caregivers, and concerns about overuse of non-affected limbs. Patients chose not to pursue transplantation due to rehabilitation time, immunosuppression, alternative treatments, and social and financial challenges. The clinical team discontinued evaluations due to unmet evaluation requirements, medical contraindications, or treatment alternatives. Different modes of shared decision-making were present depending on the party most heavily featured in the charts as driving decisions. DISCUSSION: This was an examination of shared decision-making with hand transplant candidates who did not proceed to transplant. Reasons for choosing alternative strategies for management were multifactorial. Lessons learned regarding patient motivations and shared decision-making can inform future interventions to better support patients.

RESUMEN

BACKGROUND: Diabetes care has been traditionally focused on targeting certain levels of glycemic control. This narrow emphasis may impose burdens on patients, including high treatment costs, illness-related work, or side effects from medications, while leaving other patient needs and goals under-addressed. The authors aim to shift the paradigm of care for people with diabetes, to focus on quality of life, burden of treatment, safety, and avoidance of future events: the QBSAfe domains. METHODS: We describe a single-arm pilot study to assess the feasibility and acceptability of using the QBSAfe agenda setting kit (ASK) during routine clinical visits. The set of 14 conversation aid cards was co-developed with patients, family caregivers, and clinicians. The ASK will be used in the context of a clinic visit, which will be recorded by members of the study team to identify patterns of clinician-patient conversations. Feasibility will be measured by the number of participants recruited, time to goal accrual, and completeness of data collection; acceptability will be assessed using post-visit surveys of patients and clinicians. A subgroup of patients will be invited to participate in post-visit qualitative semi-structured interviews for additional feedback. This study will be conducted across three medical centers in the Midwest and East Coast of the USA. DISCUSSION: Current healthcare infrastructure and associated demands and pressures on clinicians make changes in care difficult. However, this intervention has the potential to shift conversations during clinical encounters so they can address and directly respond to patient needs, symptoms, and capacity. As part of the QBSAfe ASK, the authors are also actively collaborating with a variety of stakeholders to create tools to help clinicians respond more effectively to patient concerns as they are raised during the clinical encounters. Additional insights about the use of the QBSAfe approach in the virtual space will be gathered during the process of our study due to restrictions imposed upon face to face visit during the COVID-19 pandemic. TRIAL REGISTRATION: ClinicalTrials.gov , NCT04514523 . Registered 17 August 2020-retrospectively registered.

RESUMEN

Inborn errors of cholesterol metabolism occur as a result of mutations in the cholesterol synthesis pathway (CSP). Although mutations in the CSP cause a multiple congenital anomaly syndrome, craniofacial abnormalities are a hallmark phenotype associated with these disorders. Previous studies have established that mutation of the zebrafish hmgcs1 gene (Vu57 allele), which encodes the first enzyme in the CSP, causes defects in craniofacial development and abnormal neural crest cell (NCC) differentiation. However, the molecular mechanisms by which the products of the CSP disrupt NCC differentiation are not completely known. Cholesterol is known to regulate the activity of WNT signaling, an established regulator of NCC differentiation. We hypothesized that defects in cholesterol synthesis are associated with reduced WNT signaling, consequently resulting in abnormal craniofacial development. To test our hypothesis we performed a combination of pharmaceutical inhibition, gene expression assays, and targeted rescue experiments to understand the function of the CSP and WNT signaling during craniofacial development. We demonstrate reduced expression of four canonical WNT downstream target genes in homozygous carriers of the Vu57 allele and reduced axin2 expression, a known WNT target gene, in larvae treated with Ro-48-8071, an inhibitor of cholesterol synthesis. Moreover, activation of WNT signaling via treatment with WNT agonist I completely restored the craniofacial defects present in a subset of animals carrying the Vu57 allele. Collectively, these data suggest interplay between the CSP and WNT signaling during craniofacial development.
