ImportanceRedirection of care refers to withdrawal, withholding, or limiting escalation of treatment. Whether maternal social determinants of health are associated with redirection of care discussions merits understanding.ObjectiveTo examine associations between maternal social determinants of health and redirection of care discussions for infants born extremely preterm.Design, Setting, and ParticipantsThis is a retrospective analysis of a prospective cohort of infants born at less than 29 weeks’ gestation between April 2011 and December 2020 at 19 National Institute of Child Health and Human Development Neonatal Research Network centers in the US. Follow-up occurred between January 2013 and October 2023. Included infants received active treatment at birth and had mothers who identified as Black or White. Race was limited to Black and White based on service disparities between these groups and limited sample size for other races. Maternal social determinant of health exposures were education level (high school nongraduate or graduate), insurance type (public/none or private), race (Black or White), and ethnicity (Hispanic or non-Hispanic).Main Outcomes and MeasuresThe primary outcome was documented discussion about redirection of infant care. Secondary outcomes included subsequent redirection of care occurrence and, for those born at less than 27 weeks’ gestation, death and neurodevelopmental impairment at 22 to 26 months’ corrected age.ResultsOf the 15 629 infants (mean [SD] gestational age, 26 [2] weeks; 7961 [51%] male) from 13 643 mothers, 2324 (15%) had documented redirection of care discussions. In unadjusted comparisons, there was no significant difference in the percentage of infants with redirection of care discussions by race (Black, 1004/6793 [15%]; White, 1320/8836 [15%]) or ethnicity (Hispanic, 291/2105 [14%]; non-Hispanic, 2020/13 408 [15%]). However, after controlling for maternal and neonatal factors, infants whose mothers identified as Black or as Hispanic were less likely to have documented redirection of care discussions than infants whose mothers identified as White (Black vs White adjusted odds ratio [aOR], 0.84; 95% CI, 0.75-0.96) or as non-Hispanic (Hispanic vs non-Hispanic aOR, 0.72; 95% CI, 0.60-0.87). Redirection of care discussion occurrence did not differ by maternal education level or insurance type.Conclusions and RelevanceFor infants born extremely preterm, redirection of care discussions occurred less often for Black and Hispanic infants than for White and non-Hispanic infants. It is important to explore the possible reasons underlying these differences.

Summary Background Stricturing Crohn's disease (CD) occurs most commonly in the terminal ileum and poses a clinical problem. Cross‐sectional imaging modalities such as intestinal ultrasound (IUS), computed tomography enterography (CTE), and magnetic resonance enterography (MRE) allow for assessment of the entire bowel wall and associated peri‐enteric findings. Radiologic definitions of strictures have been developed for CTE and MRE; their reliability and responsiveness are being evaluated in index development programs. A comprehensive assessment strategy for strictures using IUS is needed. Aims To provide a detailed summary of definitions, diagnosis and monitoring of strictures on IUS as well as technical aspects of image acquisition. Methods We searched four databases up to 6 January 2024. Two‐stage screening was done in duplicate. We assessed risk of bias using QUADAS‐2. Results There were 56 studies eligible for inclusion. Definitions for strictures on IUS are heterogeneous, but the overall accuracy for diagnosis of strictures is high. The capability of IUS for characterising inflammation versus fibrosis in strictures is not accurate enough to be used in clinical practice or trials. We summarise definitions for improvement of strictures on IUS, and discuss parameters for image acquisition and standardisation. Conclusions This systematic review is the first step for a structured program to develop a stricture IUS index for CD.

PURPOSE Daratumumab is an anti-CD38 monoclonal antibody used to treat multiple myeloma and light chain amyloidosis. Because daratumumab may cause reactions after intravenous or subcutaneous (SC) administration, the manufacturer labeling recommends administration of premedications before every dose. Given incidence of infusion reactions appears to be rare after cycle 1, in April 2022, the Mayo Clinic implemented a practice change in which premedications were omitted from all daratumumab order sets after completion of cycle 1. This study investigated the safety of this practice. METHODS A retrospective chart review at the Mayo Clinic reviewed eligible patients with multiple myeloma or amyloid light-chain (AL) amyloidosis who received their first dose of daratumumab within the 4 months preceding the date of implementation (preimplementation group) or no more than 4 months after (postimplementation group) the date of implementation on April 13, 2022. Data were collected only from the first eight once per week doses of daratumumab. The primary outcome was the incidence of infusion-related reactions. Data analyzed used descriptive statistics. RESULTS Nearly all patients (95.9%) received daratumumab by SC route of administration. Of the 97 patients in the preimplementation group, >90% received premedications throughout cycles 1 and 2, and five patients (5.2%) experienced infusion reactions. Of 72 patients in the postimplementation group, <20% received premedications during cycle 2 and three patients (4.2%) experienced infusion reactions. All infusion reactions occurred within the first daratumumab cycle, indicating elimination of cycle 2 premedications did not cause any infusion reactions. No patient experienced more than one infusion reaction. CONCLUSION Omission of premedications after cycle 1 of daratumumab did not increase the incidence of infusion. Premedications may safely be omitted after cycle 1 of daratumumab when administered by the SC route.

Hemophagocytic lymphohistiocytosis (HLH) secondary to tick-borne infections is a rare but potentially life-threatening syndrome. We performed a scoping review according to PRISMA guidelines to systematically analyze the existing literature on the topic. A total of 98 patients were included, with a mean age of 43.7 years, of which 64% were men. Most cases, 31%, were reported from the USA. Immunosuppression was present in 21.4%, with the most common cause being previous solid organ transplantation. Constitutional symptoms were the most common, observed in 83.7% of the patients, while fever was reported in 70.4% of cases. Sepsis was present in 27.6%. The most common laboratory abnormalities in this cohort were thrombocytopenia in 81.6% of patients, while anemia, leukopenia, and leukocytosis were observed in 75.5%, 55.1%, and 10.2%, respectively. Liver enzyme elevation was noted in 63.3% of cases. The H-score was analyzed in 64 patients, with the mean value being 209, and bone marrow analysis was performed in 61.2% of patients. Ehrlichia spp. was the main isolated agent associated with HLH in 45.9%, followed by Rickettsia spp. in 14.3% and Anaplasma phagocytophilum in 12.2%. Notably, no patient with Powassan virus infection or Lyme borreliosis developed HLH. The most common complications were acute kidney injury (AKI) in 35.7% of patients, shock with multiple organ dysfunction in 22.5%, encephalopathy/seizure in 20.4%, respiratory failure in 16.3%, and cardiac complications in 7.1% of patients. Treatment included antibiotic therapy alone in 43.9%, while 5.1% of patients were treated with immunosuppressants alone. Treatment with both antibiotics and immunosuppressants was used in 51% of patients. Appropriate empiric antibiotics were used in 62.2%. In 43.9% of cases of HLH due to tick-borne disease, patients received only antimicrobial therapy, and 88.4% of those recovered completely without the need for immunosuppressive therapy. The mortality rate in our review was 16.3%, and patients who received inappropriate or delayed empiric therapy had a worse outcome. Hence, we suggest empiric antibiotic treatment in patients who are suspected of having HLH due to tick-borne disease or in whom diagnostic uncertainty persists due to diagnostic delay in order to minimize mortality.

AbstractGenetic counselors are an integral part of the healthcare system; however, the number of genetic counselors in many parts of the United States is limited, impacting access to comprehensive healthcare for all patients. One solution to addressing this deficit includes modifying genetic counseling training programs to increase student enrollment. Fieldwork capacity, driven by a limited number of rotation sites and supervisors, produces a significant bottleneck to entering the profession. Other professions have reported on techniques to increase fieldwork capacity; however, the practicality of these techniques for genetic counseling training has yet to be explored. This study seeks to investigate the perspectives of key stakeholders in genetic counseling training programs on the practicality of techniques already posited in the literature from other allied health professions. Semi‐structured focus group interviews with 25 participants were conducted at the 2019 National Society of Genetic Counselors conference. Participants included program directors and supervisors from clinical, industry, and laboratory backgrounds. The focus group responses were analyzed using directed content analysis and a split coding technique, after which several themes emerged within the larger domains of rotation structures, systems infrastructure, skill‐building methods, and other novel techniques to increase fieldwork capacity. Emerging themes included the importance of finding quality student placements rather than maximizing the quantity of participatory cases; a need for transparency about the transferability of skills learned from novel experiences; scaffolding student entrustment to expand supervisor capacity; and recognizing nuances in implementation for individual programs. Overall, the results emphasize the importance of openness in communication to manage expectations for students and supervisors, who may be more hesitant to try novel rotation placements and skill‐building techniques. Genetic counseling programs may use these results to address the bottleneck of fieldwork capacity, increasing student enrollment.

(1) Background: Cardiomyopathy in celiac disease or celiac cardiomyopathy (CCM) is a serious and potentially life-threatening disease that can occur in both adults and children. However, data supporting the causal relationship between celiac disease (CD) and cardiomyopathy (CMP) are still inconsistent. The aim of this study was to review and synthesize data from the literature on this topic and potentially reveal a more evidence-based causal relationship. (2) Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to search Medline, Embase, and Scopus databases from database inception until September 2023. A total of 1187 original articles were identified. (3) Results: We identified 28 CCM patients (19 adult and 9 pediatric) with a mean age of 27.4 ± 18.01 years. Adult patients with CCM were predominantly male (84.2%) while pediatric patients were predominantly female (75%). The most common comorbidities associated with CCM were anemia (75%) and pulmonary hemosiderosis (20%). In 35% of patients, CCM occurred before the diagnosis of CD, while in 48% of patients, CCM and CD were diagnosed at the same time. Diagnosis of CD preceded diagnosis of CCM in only 18% of patients. Diagnosis of CCM is often delayed with an average, from the onset of symptoms to diagnosis, of 16 months. All patients were treated with a gluten-free diet in addition to guideline-directed medical therapy. At 11-month follow-up, cardiovascular improvement was seen in 60.7% of patients. Pediatric mortality was 33.3%, while adult mortality was 5.3%. (4) Conclusions: Clinicians should be aware of the possible association between CD and CMP, and we recommend CD work-up in all patients with CMP who have concomitant anemia. While we identified only 28 cases in the literature, many cases might go unreported due to a lack of awareness regarding CCM. A high degree of clinical suspicion and a prompt diagnosis of CCM are essential to minimizing the risks of morbidity and mortality, as the combination of a gluten-free diet and guideline-directed medical therapy can improve clinical outcomes.

Abstract In a great partnership, the Federation of European Neuroscience Societies (FENS) and the Hertie Foundation organized the FENS‐Hertie 2022 Winter School on ‘Neuro‐immune interactions in health and disease’. The school selected 27 PhD students and 13 postdoctoral fellows from 20 countries and involved 14 faculty members experts in the field. The Winter School focused on a rising field of research, the interactions between the nervous and both innate and adaptive immune systems under pathological and physiological conditions. A fine‐tuned neuro‐immune crosstalk is fundamental for healthy development, while disrupted neuro‐immune communication might play a role in neurodegeneration, neuroinflammation and aging. However, much is yet to be understood about the underlying mechanisms of these neuro‐immune interactions in the healthy brain and under pathological scenarios. In addition to new findings in this emerging field, novel methodologies and animal models were presented to foment research on neuro‐immunology. The FENS‐Hertie 2022 Winter School provided an insightful knowledge exchange between students and faculty focusing on the latest discoveries in the biology of neuro‐immune interactions while fostering great academic and professional opportunities for early‐career neuroscientists from around the world.

Abstract Purpose: Describe spirituality’s role in a sample of Hispanic adolescent and young adult (AYA) cancer survivors. Methods: This convergent parallel mixed-methods study aimed to explore participants’ lived experiences with hope during cancer treatments and cancer survivorship. A purposive sample of Hispanic AYAs aged 18-39 years who completed cancer treatments 2-5 years ago were virtually recruited for participation. First, participants completed surveys about hope, demoralization, depression and anxiety, and health related quality of life. Second, participants completed virtual semi-structured interviews about their experiences with hope during cancer treatments and cancer survivorship and prepared narratives about their experiences. Thematic analyses were iteratively performed across the data set to identify final themes. Results: Ten Hispanic AYA cancer survivors aged 22-36 years old participated in this pilot study. Seven participants (70%) were female, and three participants (30%) were male. Six participants (60%) experienced non-hematologic malignancies, and four participants (40%) experienced hematologic malignancies. Eight participants (80%) preferred to participate using Spanish, while two (20%) preferred to participate using English. The theme Spirituality, and subthemes Living by Faith, God as a Resource, and Spiritual Gratitude were identified as concepts participants linked to their conceptualization of hope during cancer treatment and survivorship. Conclusions: Hope and spirituality may be conceptually linked to coping behaviors among Hispanic AYA cancer survivors. Hope through faith may be a learned spiritual value in Hispanic AYAs and might play a role in their spiritual and cognitive development. Further research is needed to explore the potentially protective value of hope and spirituality for the Hispanic AYA population.

688 Background: PACC is a rare malignancy originating from the exocrine pancreas, accounting for less than 1% of all pancreatic cancers. Due to the rarity of the disease entity, there is a paucity of data to guide treatment decisions. This retrospective study aims to provide additional clinical characteristics and outcomes to aid in future treatment decisions. Methods: Pathology records from Mayo Clinic (AZ, FL, MN) patients (pts) denoting acinar or mixed-acinar cell carcinoma were searched between 2002 to 2023 and selected for retrospective review. Pt demographics, treatment courses, and next generation sequencing (NGS) were collected. Results: A total of 62 pts (74% male, n = 46) were identified with median age 64 years old. Histologic subtypes were 67% pure acinar cell carcinoma (42/62), 24% mixed acinar-neuroendocrine (15/62), and 8% mixed acinar-adenocarcinoma (5/62). AJCC stages at diagnosis were 34% stage I/II (21/62), 16% stage III (10/62), and 50% stage IV (31/62). Early-stage disease was treated with upfront surgical resection (81%, 17/21). Locally advanced disease received neoadjuvant therapy (NAT) followed by surgical resection (80%, 8/10). FOLFIRINOX was most often chosen as NAT (65%, 11/17), while others received gemcitabine-based NAT. The R0 resection rate was 86%. The 3 and 5-year survival estimates for stage III were 90.9% (95% CI: 75.4 – 100%) and 67.3% (95% CI: 42.3 – 100%), respectively. The 3 and 5-year survival estimates for stage IV were 36.6% (95% CI: 18.6 – 71.9%) and 29.3% (95% CI: 13.1 – 65.5%), respectively. Median survival time for stage IV was 3 years. Somatic NGS testing was done in 24 pts with alterations found in: homologous recombination (HR) in 42% (10/24); RAF alterations in 25% (6/24); mismatch repair (MMR) in 13% (3/24; none of them with MMR germline mutations), 1 ETV6-NTRK3 fusion, and 1 FGFR mutation. Germline NGS testing was done in 21 pts and alterations in HR were seen in 33% (7/21) of pts. This led to additional therapeutic options in 46% (11/24) of pts. Conclusions: Unlike PDAC, PACC is a genomically diverse disease, with potentially targetable alterations in RAF, HRD, and MMR genes, offering additional therapeutic options for significant number of pts. In addition, more than one-third of the pts harbored germline mutations in HR genes. Therefore, somatic and germline testing should be considered for any pt diagnosed with PACC.
