ABSTRACT
Pediatric solid tumors are rare malignancies that represent a leading cause of death by disease among children in developed countries. The early age-of-onset of these tumors suggests that germline genetic factors are involved, yet conventional germline testing for short coding variants in established predisposition genes only identifies pathogenic events in 10-15% of patients. Here, we examined the role of germline structural variants (SVs)-an underexplored form of germline variation-in pediatric extracranial solid tumors using germline genome sequencing of 1,766 affected children, their 943 unaffected relatives, and 6,665 adult controls. We discovered a sex-biased association between very large (>1 megabase) germline chromosomal abnormalities and a four-fold increased risk of solid tumors in male children. The overall impact of germline SVs was greatest in neuroblastoma, where we revealed burdens of ultra-rare SVs that cause loss-of-function of highly expressed, mutationally intolerant, neurodevelopmental genes, as well as noncoding SVs predicted to disrupt three-dimensional chromatin domains in neural crest-derived tissues. Collectively, our results implicate rare germline SVs as a predisposing factor to pediatric solid tumors that may guide future studies and clinical practice.
ABSTRACT
Objectives: To provide a comprehensive summary of the different modalities available to measure soft tissue fibrosis after radiotherapy in head and neck cancer patients. Data Sources: PubMed, Scopus, and Web of Sciences. Review Methods: A search was conducted using a list of medical subject headings and terms related to head and neck oncology, radiation fibrosis, and quantitative measurements, including bioimpedance, MRI, and ultrasound. Original research related to quantitative measurement of neck fibrosis post-radiotherapy was included without time constraints, while reviews, case reports, non-English texts, and inaccessible studies were excluded. Discrepancies during the review were resolved by discussing with the senior author until consensus was reached. Results: A total of 284 articles were identified and underwent title and abstract screening. Seventeen articles had met our criteria for full-text review based on relevance, of which nine had met our inclusion criteria. Young's modulus (YM) and viscoelasticity measures have demonstrated efficacy in quantifying neck fibrosis, with fibrotic tissues displaying significantly higher YM values and altered viscoelastic properties such as increased stiffness rate-sensitivity and prolonged stress-relaxation post-radiation. Intravoxel incoherent motion offers detailed insights into tissue changes by assessing the diffusion of water molecules and blood perfusion, thereby differentiating fibrosed from healthy tissues. Shear wave elastography has proven to be an effective technique for quantifying radiation-induced fibrosis in the head and neck region by measuring shear wave velocity. Conclusion: There are various modalities to measure radiation-induced fibrosis, each with its unique strengths and limitations. Providers should be aware of these implications and decide on methodologies based on their specific clinical workflow. Level of Evidence: Step 5.
ABSTRACT
Background Panel management is essential for residents to learn, yet challenging to teach. To our knowledge, prior literature has not described curricula utilizing a financially incentivized competition to improve resident primary care metrics. Objective We developed a panel management curriculum, including a financially incentivized quality competition, to improve resident performance on quality metrics. Methods We developed a cancer screening and diabetes metric quality competition for internal medicine residents at Vanderbilt University Medical Center for their primary care clinics for the 2020-2021 (pilot) and 2021-2022 academic years. Residents received several educational tools, including a 1-hour introduction to the health maintenance dashboard within the electronic medical record (EMR) and instructions on how to access the quality dashboard outside the EMR, and were encouraged to discuss panel management with preceptors. Chief residents distributed measures to trainees 3 times annually, so residents were aware of their competition ranking. Residents' composite metrics at year end were compared to baseline to determine top performers. The top 15 performers received $100 gift cards as incentives. We also assessed the curriculum's impact on the residents' metrics in aggregate. Results At curriculum completion, residents (n=100) demonstrated an average improvement of 1.9% from baseline composite metrics for the percent of patients receiving screening. In aggregate, residents improved in every measure except HbA1c testing. Breast cancer screening had the largest improvement from 69.5% (1518 of 2183) to 75.6% (1646 of 2178) of all patients receiving recommended screening. Conclusions The curriculum resulted in more patients receiving recommended cancer and diabetes screenings.

Background: Medulloblastoma is the most common malignant pediatric brain tumor, and leptomeningeal dissemination (LMD) of medulloblastoma both portends a poorer prognosis at diagnosis and is incurable at recurrence. The biological mechanisms underlying LMD are unclear. The Abelson (ABL) tyrosine kinase family members, ABL1 and ABL2, have been implicated in cancer cell migration, invasion, adhesion, metastasis, and chemotherapy resistance, and are upstream mediators of the oncogene c-MYC in fibroblasts and lung cancer cells. However, their role in medulloblastoma has not yet been explored. The purpose of this work was to elucidate the role of ABL1/2 in medulloblastoma LMD. Methods: ABL1 and ABL2 mRNA expression of patient specimens was analyzed. shRNA knockdowns of ABL1/2 and pharmacologic inhibition of ABL1/2 were used for in vitro and in vivo analyses of medulloblastoma LMD. RNA sequencing of ABL1/2 genetic knockdown versus scrambled control medulloblastoma was completed. Results: ABL1/2 mRNA is highly expressed in human medulloblastoma and pharmacologic inhibition of ABL kinases resulted in cytotoxicity. Knockdown of ABL1/2 resulted in decreased adhesion of medulloblastoma cells to the extracellular matrix protein, vitronectin (Pâ =â .0013), and significantly decreased tumor burden in a mouse model of medulloblastoma LMD with improved overall survival (Pâ =â .0044). Furthermore, both pharmacologic inhibition of ABL1/2 and ABL1/2 knockdown resulted in decreased expression of c-MYC, identifying a putative signaling pathway, and genes/pathways related to oncogenesis and neurodevelopment were differentially expressed between ABL1/2 knockdown and control medulloblastoma cells. Conclusions: ABL1 and ABL2 have potential roles in medulloblastoma LMD upstream of c-MYC expression.
ABSTRACT
This document is part of the "SHEA Neonatal Intensive Care Unit (NICU) White Paper Series." It is intended to provide practical, expert opinion, and/or evidence-based answers to frequently asked questions about CLABSI detection and prevention in the NICU. This document serves as a companion to the CDC Healthcare Infection Control Practices Advisory Committee (HICPAC) Guideline for Prevention of Infections in Neonatal Intensive Care Unit Patients. Central line-associated bloodstream infections (CLABSIs) are among the most frequent invasive infections among infants in the NICU and contribute to substantial morbidity and mortality. Infants who survive CLABSIs have prolonged hospitalization resulting in increased healthcare costs and suffer greater comorbidities including worse neurodevelopmental and growth outcomes. A bundled approach to central line care practices in the NICU has reduced CLABSI rates, but challenges remain. This document was authored by pediatric infectious diseases specialists, neonatologists, advanced practice nurse practitioners, infection preventionists, members of the HICPAC guideline-writing panel, and members of the SHEA Pediatric Leadership Council. For the selected topic areas, the authors provide practical approaches in question-and-answer format, with answers based on consensus expert opinion within the context of the literature search conducted for the companion HICPAC document and supplemented by other published information retrieved by the authors. Two documents in the series precede this one: "Practical approaches to Clostridioides difficile prevention" published in August 2018 and "Practical approaches to Staphylococcus aureus prevention," published in September 2020.

BACKGROUND: Brain cancer incidence and mortality rates are greater in males. Understanding the molecular mechanisms that underlie those sex differences could improve treatment strategies. Although sex differences in normal metabolism are well described, it is currently unknown whether they persist in cancerous tissue. METHODS: Using positron emission tomography (PET) imaging and mass spectrometry, we assessed sex differences in glioma metabolism in samples from affected individuals. We assessed the role of glutamine metabolism in male and female murine transformed astrocytes using isotope labeling, metabolic rescue experiments, and pharmacological and genetic perturbations to modulate pathway activity. FINDINGS: We found that male glioblastoma surgical specimens are enriched for amino acid metabolites, including glutamine. Fluoroglutamine PET imaging analyses showed that gliomas in affected male individuals exhibit significantly higher glutamine uptake. These sex differences were well modeled in murine transformed astrocytes, in which male cells imported and metabolized more glutamine and were more sensitive to glutaminase 1 (GLS1) inhibition. The sensitivity to GLS1 inhibition in males was driven by their dependence on glutamine-derived glutamate for α-ketoglutarate synthesis and tricarboxylic acid (TCA) cycle replenishment. Females were resistant to GLS1 inhibition through greater pyruvate carboxylase (PC)-mediated TCA cycle replenishment, and knockdown of PC sensitized females to GLS1 inhibition. CONCLUSION: Our results show that clinically important sex differences exist in targetable elements of metabolism. Recognition of sex-biased metabolism may improve treatments through further laboratory and clinical research. FUNDING: This work was supported by NIH grants, Joshua's Great Things, the Siteman Investment Program, and the Barnard Research Fund.

For many cancer patients, chemotherapy produces untreatable life-long neurologic effects termed chemotherapy-related cognitive impairment (CRCI). We discovered that the chemotherapy methotrexate (MTX) adversely affects oxidative metabolism of non-cancerous choroid plexus (ChP) cells and the cerebrospinal fluid (CSF). We used a ChP-targeted adeno-associated viral (AAV) vector approach in mice to augment CSF levels of the secreted antioxidant SOD3. AAV-SOD3 gene therapy increased oxidative defense capacity of the CSF and prevented MTX-induced lipid peroxidation in the hippocampus. Furthermore, this gene therapy prevented anxiety and deficits in short-term learning and memory caused by MTX. MTX-induced oxidative damage to cultured human cortical neurons and analyses of CSF samples from MTX-treated lymphoma patients demonstrated that MTX diminishes antioxidant capacity of patient CSF. Collectively, our findings motivate the advancement of ChP- and CSF-targeted anti-oxidative prophylactic measures to relieve CRCI.

We conducted a pilot diagnostic randomized clinical trial (RCT) to examine the feasibility, acceptability, and preliminary outcomes of adding bowel ultrasound (BUS) to the diagnostic evaluation for necrotizing enterocolitis (NEC). Infants ≤ 32 weeks' gestational age with NEC concern were randomized to undergo abdominal X-ray (AXR) or AXR + BUS. The primary outcome was study feasibility. Secondary outcomes included rates of NEC diagnosis and duration of treatment with bowel rest and antibiotics. A total of 56 infants were enrolled; 16 developed NEC concern and were randomized. Rates of recruitment (56/82 = 68%), retention (16/16 = 100%), and protocol compliance (126/127 = 99%) met pre-specified thresholds for feasibility. No significant differences in rates of NEC diagnosis were found between the two groups. Durations of bowel rest and antibiotic treatment were also similar. Conclusion: Our study supports the feasibility of conducting a definitive diagnostic RCT to establish safety and efficacy of BUS for NEC. Clinical trial registration: The study was registered at https://clinicaltrials.gov (NCT03963011). What is Known: ⢠Bowel ultrasound (BUS) is increasingly being utilized as an adjunct to abdominal radiographs in evaluating for necrotizing enterocolitis (NEC). ⢠The impact of BUS on patient outcomes is unknown. What is New: ⢠A diagnostic randomized controlled trial study design to determine safety and effectiveness of adding BUS to NEC evaluation is feasible and acceptable.

More knowledge is needed regarding germline predisposition to Ewing sarcoma to inform biological investigation and clinical practice. Here, we evaluated the enrichment of pathogenic germline variants in Ewing sarcoma relative to other pediatric sarcoma subtypes, as well as patterns of inheritance of these variants. We carried out European-focused and pan-ancestry case-control analyses to screen for enrichment of pathogenic germline variants in 141 established cancer predisposition genes in 1,147 individuals with pediatric sarcoma diagnoses (226 Ewing sarcoma, 438 osteosarcoma, 180 rhabdomyosarcoma, and 303 other sarcoma) relative to identically processed cancer-free control individuals. Findings in Ewing sarcoma were validated with an additional cohort of 430 individuals, and a subset of 301 Ewing sarcoma parent-proband trios was analyzed for inheritance patterns of identified pathogenic variants. A distinct pattern of pathogenic germline variants was seen in Ewing sarcoma relative to other sarcoma subtypes. FANCC was the only gene with an enrichment signal for heterozygous pathogenic variants in the European Ewing sarcoma discovery cohort (three individuals, OR 12.6, 95% CI 3.0-43.2, p = 0.003, FDR = 0.40). This enrichment in FANCC heterozygous pathogenic variants was again observed in the European Ewing sarcoma validation cohort (three individuals, OR 7.0, 95% CI 1.7-23.6, p = 0.014), representing a broader importance of genes involved in DNA damage repair, which were also nominally enriched in individuals with Ewing sarcoma. Pathogenic variants in DNA damage repair genes were acquired through autosomal inheritance. Our study provides new insight into germline risk factors contributing to Ewing sarcoma pathogenesis.

Renal allograft strangulation is a rare complication following simultaneous kidney pancreas transplant, often causing graft loss. This case report represents the first documented case of a 35-year-old female who developed renal graft strangulation around the left fallopian tube. Our case outlines a new complication that contributes to graft loss concerning iliac fossa anatomy and variations in female patients, as well as surgical considerations that need to be made prior to transplantation. We recommend measurement of the grafted renal vessels within the iliac fossa and respective surroundings structures to allow for the ideal positioning of the grafted organ.
ABSTRACT
BACKGROUND & PURPOSE: The COVID-19 pandemic has negatively impacted mental health in the general population. In this trial, our objective was to assess whether a 6-week expressive writing intervention improves resilience in a sample from the general population in the midst of the COVID-19 pandemic. MATERIALS & METHODS: This 6-week trial was conducted online. Eligible participants (n=63) were a sample of adults who self-identified as having been significantly affected by the COVID-19 pandemic. PRIMARY OUTCOME: Connor-Davidson Resilience Scale (CD-RISC). SECONDARY OUTCOMES: Perceived Stress Scale - 10-Item (PSS-10); Center for Epidemiologic Studies Depression Scale - Revised (CESD-R); Post-Traumatic Growth Inventory (PTGI). RESULTS: Resilience measures (CD-RISC) increased from baseline (66.6 ± 14.9) to immediately post-intervention (73.0 ± 12.4; p=0.014; Cohen's d =0.31), and at a 1- month follow-up (72.9 ± 13.6; p=0.024; Cohen's d =0.28). Across the same timepoints, perceived stress scores (PSS-10) decreased from baseline (21.8 ± 6.6) to immediately post-intervention (18.3 ± 7.0; p=0.008; Cohen's d =0.41), and at the 1- month follow-up to (16.8 ± 6.7; p=0.0002; Cohen's d =0.56). Depression symptoms (CESD-R) decreased from baseline (23.3 ± 15.3) at 6 weeks (17.8 ± 15.4; p=0.058; Cohen's d =0.22), and 10 weeks (15.5 ± 12.7; p=0.004; Cohen's d =0.38). Posttraumatic growth (PTGI) increased from baseline (41.7 ± 23.4) at 6 weeks (55.8 ± 26.4; p=0.004; Cohen's d =0.44), and at the 1-month follow-up (55.9 ± 29.3; p=0.008; Cohen's d =0.49). CONCLUSION: An online expressive writing intervention was effective at improving resilience in the midst of the COVID-19 pandemic. NCT#: NCT04589104.

Childhood cancer is a stressful experience. No pediatric patient, however, should be made to feel as if their concerns and feelings about their cancer experience must be bottled up inside. Importantly, talking and writing about one's illness has myriad implications for young cancer patients and survivors. The most salient of these may include increased understanding of one's condition as well as improved physical and cognitive symptoms (e.g., lowered depression, decreased anxiety, and an enhanced quality of life overall). This literature review explores three promising avenues for verbal therapy in the pediatric oncology setting: expressive writing, video narratives, and bibliotherapy exercises. Several recent studies, covering verbal therapy methods from illness blogging to book interventions, are referenced and discussed. Ultimately, we conclude that expressive writing, video narratives, and bibliotherapy exercises are valuable, feasible, inexpensive, and acceptable tools for patients and survivors of childhood cancer to facilitate self-expression-and to find meaning in the uncertainty and anxiety that cancer inherently fosters. We recommend that future studies investigate this theme so that we may improve quality of life and mental health for pediatric cancer patients and survivors worldwide.
ABSTRACT
Individuals with Down's syndrome rely on caregivers to support lifestyle behaviour change. It is therefore important to understand how caregivers put health recommendations into practice. Through conducting semi-structured interviews, the present study sought to understand the facilitators and barriers that caregivers faced when implementing health promotion advice. Five interviews were conducted with paid support staff and four with family carers of individuals attending a specialist multidisciplinary Down's syndrome health promotion screening clinic. Three main themes emerged in their accounts, including active promotion of weight management by caregivers, benefits of working practices such as record keeping and communication channels and the importance of having access to social care services and recreational activities. These findings have important implications for professionals working in specialised healthcare settings who may be able to tailor communication and services to better meet the needs of individuals with Down's syndrome and their caregivers.

Importance: Having a noninvasive tool that quantifies the amount of remaining septal cartilage in the setting of prior septoplasty would be useful for surgical planning and patient counseling. Objective: The objective of this pilot study is to determine if endocavitary ultrasound can be used to evaluate the presence and thickness of septal cartilage in vivo. Design, Setting, and Participants: A small prospective observational study was designed to assess the feasibility of using intranasal ultrasound to verify the presence and measure the thickness of septal cartilage. Imaging was undertaken by the principle investigator using a protocol developed by the research team. Six healthy volunteers were enrolled including three subjects who have had prior septoplasty. Images and measurements of the nasal septum were obtained. Main Outcomes: Confirming the presence of the nasal septum was the main outcome with a secondary outcome of measurement of septum thickness. Results: The endonasal ultrasound probe was able to identify the septum and resected areas. The mean thickness of the septum in subjects without surgery was 1.0 mm and those with prior septoplasty was 0.8 mm. Student's t-test show a statistically significant difference in septum thickness between these two groups with a p-value of 0.0093. Conclusions and Relevance: This study demonstrates a novel method of determining the presence of septal cartilage after septoplasty surgery. This information may be useful for operative planning in revision rhinoplasty.

The coronavirus disease 2019 is caused by the severe acute respiratory syndrome coronavirus 2. The virus can be spread by close person-to-person contact primarily by respiratory droplets. Given the close proximity of the sonographer or sonologist with the patient during ultrasound examinations, special precautions should be taken to limit the exposure of radiology personnel to patients with coronavirus disease 2019 while still providing optimal patient care. Methods covered in this article include modified workflow, close scrutiny and prioritization of imaging orders, and design of targeted ultrasound protocols. These guidelines summarize the personal experience and insight of multiple colleagues who lead ultrasound sections or are experts in the field.

Tyrosine kinase inhibitors have revolutionized the world of cancer treatment in recent years, profoundly improving survival of patients with chronic myeloid leukemia (CML) and beyond. However, off-target toxicities of these inhibitors are well-described, and resistance has become a paramount concern. Novel allosteric inhibitors of the Abelson (ABL) family of tyrosine kinases, including GNF-2, GNF-5, and ABL-001, are equipped to overcome these issues. Several contemporary studies have demonstrated their potential efficacy in three key areas: primary hematologic and solid malignancies, metastasis, and combination with other small molecules. Further, ongoing clinical trials are investigating the efficacy of ABL-001 for the treatment of CML and recurrent solid tumors. This work reviews the current literature of the preclinical testing of GNF-2 and GNF-5 and the preclinical and clinical testing of ABL-001. Future research will continue to evaluate these promising inhibitors as both first-line therapy for solid tumors and salvage therapy when more traditional drugs such as imatinib fail.

INTRODUCTION: We determined the usefulness of ultrasound compared to cross-sectional imaging in the detection of intra-abdominal recurrences after radical or partial nephrectomy for localized renal cell carcinoma. METHODS: We performed a retrospective review of 800 patients with clinically localized renal cell carcinoma who had undergone radical or partial nephrectomy between 2008 and 2015. Patients had at minimum 1 year of followup at our institution, at least 1 ultrasound during surveillance and no metastases at time of surgery. Our primary outcome was the rate of diagnosis of abdominal recurrence based on modality of surveillance. RESULTS: Median followup for the entire cohort was 37.5 months (range 12 to 166). Overall 396 and 404 patients underwent radical and partial nephrectomy, respectively, for localized renal cell carcinoma. There were 224 (57%) and 234 (58%) patients in the radical and partial nephrectomy cohorts, respectively, who had 2 or more ultrasounds performed during surveillance. In the radical and partial nephrectomy cohorts a total of 149 (19%) abdominal recurrences were detected, with only 8 (19%) initially detected by ultrasound. On the other hand, 15 (10%) recurrences were missed by a prior negative ultrasound. Furthermore, there were 8 false-positive ultrasound studies that cross-sectional imaging later ruled out. CONCLUSIONS: The low yield of ultrasound in the detection of abdominal recurrences after radical or partial nephrectomy for renal cell carcinoma raises questions as to its usefulness in routine surveillance.
ABSTRACT
Prior studies have shown that dose-escalated radiation therapy for prostate cancer improves clinical outcomes. However, this is associated with increased rectal toxicity. Hydrogel spacer for prostate cancer therapy is an effective way of decreasing rectal toxicity in the late post-therapeutic stages. In some occasions, the gel spacer may not be placed symmetrically between the rectum and prostate. There are several forms of a malpositioned spacer, including lateral displacement, rectal wall infiltration, and prostate capsule infiltration. This manuscript is aimed at evaluating appropriately positioned and malpositioned gel spacers, primarily via magnetic resonance imaging. There are limited educational imaging guides that address what radiologists should evaluate on post-spacer placement imaging. This pictorial review will specifically evaluate post-injection pitfalls such as asymmetry, rectal wall infiltration, and subcapsular injection.

RATIONALE AND OBJECTIVES: Adverse reactions to intravenous contrast for radiologic examinations can result in significant patient morbidity and mortality. It is critical that radiologists be proficient at recognizing and treating reactions in a timely and appropriate manner. Therefore, we developed a hands-on simulation curriculum to improve residents' ability and comfort in recognizing and responding to contrast reactions. MATERIALS AND METHODS: Contrast reaction management simulations were performed in 2016 and 2017 with 25 and 26 resident participants, respectively. Participants completed pre- and postsimulation surveys both years to assess knowledge and comfort in managing contrast reactions. RESULTS: In 2016, 25 participants answered 12 questions assessing knowledge of contrast reaction management. Percentage of correct answers increased from pre- to postsurvey in 83% of questions (10/12). Participants indicated their comfort level in managing contrast reactions increased on all six questions from pre- to postsurvey. In 2017, 26 participants answered 14 questions assessing knowledge of contrast reaction management. Similarly, percentage of correct answers increased from pre- to postsurvey in 86% of questions (12/14). Participant comfort levels also increased on all six questions from pre- to postsurvey. Subgroup analysis performed on 19 participants who completed the curriculum both years demonstrated further improvement in knowledge and comfort after completing the second year, showing added benefit of repeated simulation. CONCLUSION: These results suggest that incorporating high-fidelity contrast reaction management simulation into resident education improves both residents' knowledge and comfort in managing reactions. We have therefore incorporated annual contrast reaction simulation as a standard component of our residency curriculum.

Aesthetic medicine nursing is a highly skilled specialty, which continues to evolve. A survey of 197 experienced aesthetic medicine nurses practicing in eight countries revealed shortcomings in the current approach to their education, training, and registration. Education and training are currently self-identified and self-funded and are often provided by the companies that manufacture or distribute the products used in aesthetic medicine treatments. Accreditation and registration schemes are not mandatory, and an international professional governing body is lacking to facilitate international cooperation and sharing of best practice. There is a need for an academic, coherent, and comprehensive approach to the training and education of aesthetic medicine nurses that will equip them with the knowledge and experience to not only administer treatments and attain natural looking results but also prevent, recognize, and manage any potential complications associated with such treatments.
