Comprehensive characterization of intraductal oncocytic papillary neoplasm (IOPN) of the pancreas: a systematic and critical review.

Intraductal oncocytic papillary neoplasm (IOPN) of the pancreas is a recently recognized pancreatic tumor. Here, we aimed to determine the most essential features with the systematic review tool. PubMed, SCOPUS, and Embase were searched for studies reporting data on pancreatic IOPN. The clinicopathological, immunohistochemical, and molecular data were extracted and summarized. Then, a comparative analysis of the molecular alterations of IOPN with those of pancreatic ductal adenocarcinoma and intraductal papillary mucinous neoplasm from reference cohorts (including The Cancer Genome Atlas) was conducted. The key findings from 414 IOPNs were as follows: 1) Clinicopathological Features: Male-to-female ratio was 1,5:1. Pancreatic head was the most common site (131/237, 55.3%), but a diffuse tumor extension involving more than one pancreatic segment was described in about 1/5 of cases (49/237, 20.6%). The mean size was 45.5 mm. An associated invasive carcinoma was present in 50% of cases (168/336). In those cases, most tumors were pT1/pT2 and pN0 (>80%), and vascular invasion was uncommon (20.6%). Regarding survival, more than 90% of patients were alive after surgical resection. 2) Immunohistochemical and Molecular Features: The most expressed mucins were MUC5AC (110/112, 98.2%) and MUC6 (78/84, 92.8%). Compared with pancreatic ductal adenocarcinoma and intraductal papillary mucinous neoplasm, the classic pancreatic drivers KRAS, TP53, CDKN2A, SMAD4, and GNAS were less altered in IOPN (p<0.01). Moreover, fusions involving PRKACA or PRKACB genes were detected in all of 68 cases examined, with PRKACB::ATP1B1 as the most common (27/68 cases, 39.7%). These genomic events emerged as an entity-defining molecular alteration of IOPN (p<0.01). Thus, such fusions represent a promising biomarker for diagnostic purposes. Recent evidence also suggests their role in influencing the acquisition of oncocytic morphology. IOPN is a distinct pancreatic neoplasm with specific clinicopathological and molecular features. Considering the clinical/prognostic implications, its recognition is essential for pathologists and, ultimately, patients' management.

Clinical Relevance of Cancerization of Ducts in Resected Pancreatic Ductal Adenocarcinoma.

OBJECTIVES: Although prevalent in 50%-90% of pancreatic ductal adenocarcinomas, the clinical relevance of "cancerization of ducts" (COD) remains unknown. METHODS: Pathologists retrospectively reviewed slides classifying prevalence of COD. Histopathological parameters, location of first recurrence, recurrence-free survival (RFS), and overall survival (OS) were collected from the institutional pancreatectomy registry. RESULTS: Among 311 pancreatic ductal adenocarcinomas, COD was present in 216 (69.5%) and more prevalent in the cohort that underwent upfront surgery (75.3% vs 63.1%, P = 0.019). Furthermore, COD was associated with female gender (P = 0.040), advanced T stage (P = 0.007), perineural invasion (P = 0.014), lymphovascular invasion (P = 0.025), and R1 margin (P = 0.009), but not N stage (P = 0.401) or tumor differentiation (P = 0.717). In multivariable regression, COD was associated with less liver recurrence (odds ratio, 0.44; P < 0.005). This association was driven by the cohort of patients who had received preoperative treatment (odds ratio, 0.18; P < 0.001). COD was not predictive for RFS or OS. CONCLUSIONS: Cancerization of ducts was not associated with RFS or OS. Currently underrecognized, standardized implementation into histopathological reports may have merit, and further mechanistic scientific experiments need to illuminate its clinical and biologic impact.

A screen for Plasmodium falciparum sporozoite surface protein binding to human hepatocyte surface receptors identifies novel host-pathogen interactions.

BACKGROUND: Sporozoite invasion of hepatocytes is an essential step in the Plasmodium life-cycle and has similarities, at the cellular level, to merozoite invasion of erythrocytes. In the case of the Plasmodium blood-stage, efforts to identify host-pathogen protein-protein interactions have yielded important insights including vaccine candidates. In the case of sporozoite-hepatocyte invasion, the host-pathogen protein-protein interactions involved are poorly understood. METHODS: To gain a better understanding of the protein-protein interaction between the sporozoite ligands and host receptors, a systematic screen was performed. The previous Plasmodium falciparum and human surface protein ectodomain libraries were substantially extended, resulting in the creation of new libraries comprising 88 P. falciparum sporozoite protein coding sequences and 182 sequences encoding human hepatocyte surface proteins. Having expressed recombinant proteins from these sequences, a plate-based assay was used, capable of detecting low affinity interactions between recombinant proteins, modified for enhanced throughput, to screen the proteins for interactions. The novel interactions identified in the screen were characterized biochemically, and their essential role in parasite invasion was further elucidated using antibodies and genetically manipulated Plasmodium parasites. RESULTS: A total of 7540 sporozoite-hepatocyte protein pairs were tested under conditions capable of detecting interactions of at least 1.2 µM KD. An interaction between the human fibroblast growth factor receptor 4 (FGFR4) and the P. falciparum protein Pf34 is identified and reported here, characterizing its affinity and demonstrating the blockade of the interaction by reagents, including a monoclonal antibody. Furthermore, further interactions between Pf34 and a second P. falciparum rhoptry neck protein, PfRON6, and between human low-density lipoprotein receptor (LDLR) and the P. falciparum protein PIESP15 are identified. Conditional genetic deletion confirmed the essentiality of PfRON6 in the blood-stage, consistent with the important role of this protein in parasite lifecycle. Pf34 was refractory to attempted genetic modification. Antibodies to Pf34 abrogated the interaction and had a modest effect upon sporozoite invasion into primary human hepatocytes. CONCLUSION: Pf34 and PfRON6 may be members of a functionally important invasion complex which could be a target for future interventions. The modified interaction screening assay, protein expression libraries and P. falciparum mutant parasites reported here may be a useful tool for protein interaction discovery and antigen candidate screening which could be of wider value to the scientific community.

3D genomic mapping reveals multifocality of human pancreatic precancers.

Pancreatic intraepithelial neoplasias (PanINs) are the most common precursors of pancreatic cancer, but their small size and inaccessibility in humans make them challenging to study1. Critically, the number, dimensions and connectivity of human PanINs remain largely unknown, precluding important insights into early cancer development. Here, we provide a microanatomical survey of human PanINs by analysing 46 large samples of grossly normal human pancreas with a machine-learning pipeline for quantitative 3D histological reconstruction at single-cell resolution. To elucidate genetic relationships between and within PanINs, we developed a workflow in which 3D modelling guides multi-region microdissection and targeted and whole-exome sequencing. From these samples, we calculated a mean burden of 13 PanINs per cm3 and extrapolated that the normal intact adult pancreas harbours hundreds of PanINs, almost all with oncogenic KRAS hotspot mutations. We found that most PanINs originate as independent clones with distinct somatic mutation profiles. Some spatially continuous PanINs were found to contain multiple KRAS mutations; computational and in situ analyses demonstrated that different KRAS mutations localize to distinct cell subpopulations within these neoplasms, indicating their polyclonal origins. The extensive multifocality and genetic heterogeneity of PanINs raises important questions about mechanisms that drive precancer initiation and confer differential progression risk in the human pancreas. This detailed 3D genomic mapping of molecular alterations in human PanINs provides an empirical foundation for early detection and rational interception of pancreatic cancer.

PanIN or IPMN? Redefining Lesion Size in 3 Dimensions.

Pancreatic ductal adenocarcinoma (PDAC) develops from 2 known precursor lesions: a majority (∼85%) develops from pancreatic intraepithelial neoplasia (PanIN), and a minority develops from intraductal papillary mucinous neoplasms (IPMNs). Clinical classification of PanIN and IPMN relies on a combination of low-resolution, 3-dimensional (D) imaging (computed tomography, CT), and high-resolution, 2D imaging (histology). The definitions of PanIN and IPMN currently rely heavily on size. IPMNs are defined as macroscopic: generally >1.0 cm and visible in CT, and PanINs are defined as microscopic: generally <0.5 cm and not identifiable in CT. As 2D evaluation fails to take into account 3D structures, we hypothesized that this classification would fail in evaluation of high-resolution, 3D images. To characterize the size and prevalence of PanINs in 3D, 47 thick slabs of pancreas were harvested from grossly normal areas of pancreatic resections, excluding samples from individuals with a diagnosis of an IPMN. All patients but one underwent preoperative CT scans. Through construction of cellular resolution 3D maps, we identified >1400 ductal precursor lesions that met the 2D histologic size criteria of PanINs. We show that, when 3D space is considered, 25 of these lesions can be digitally sectioned to meet the 2D histologic size criterion of IPMN. Re-evaluation of the preoperative CT images of individuals found to possess these large precursor lesions showed that nearly half are visible on imaging. These findings demonstrate that the clinical classification of PanIN and IPMN fails in evaluation of high-resolution, 3D images, emphasizing the need for re-evaluation of classification guidelines that place significant weight on 2D assessment of 3D structures.

A service evaluation of measuring fluid responsiveness in acutely unwell hypotensive patients outside of critical care.

INTRODUCTION: Early recognition and prompt, appropriate management may reduce mortality in patients with sepsis. The Surviving Sepsis Campaign's guidelines suggest the use of dynamic measurements to guide fluid resuscitation in sepsis; although these methods are rarely employed to monitor cardiac output in response to fluid administration outside intensive care units. This service evaluation investigated the introduction of a nurse led protocolised goal-directed fluid management using a non-invasive cardiac output monitor to the standard assessment of hypotensive ward patients. METHODS: We introduced the use of a goal-directed fluid management protocol into our critical care outreach teams' standard clinical assessment. Forty-nine sequential patients before and thirty-nine after its introduction were included in the assessment. RESULTS: Patients in the post-intervention cohort received less fluid in the 6 h following outreach assessment (750mls vs 1200mls). There were no differences in clinical background or rates of renal replacement therapy, but rates of invasive and non-invasive ventilation were reduced (0% vs 31%). Although the groups were similar, the post-intervention patients had lower recorded blood pressures. CONCLUSION: IV fluid therapy in the patient with hypotension complicating sepsis can be challenging. Excessive IV fluid administration is commonplace and associated with harm, and the use of advanced non-invasive haemodynamic monitoring by trained nurses can provide objective evaluation of individualised response to treatment. Avoiding excessive IV fluid and earlier institution of appropriate vasopressor therapy may improve patient outcomes. IMPLICATIONS FOR CLINICAL PRACTICE: Adoption of dynamic measures of cardiac output outside of critical care by trained critical care nurses is feasible and may translate into improved patient outcomes. In hospitals with a nurse-led critical care outreach service, consideration should be given to such an approach.

Understanding familial risk of pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease that is the result of an accumulation of sequential genetic alterations. These genetic alterations can either be inherited, such as pathogenic germline variants that are associated with an increased risk of cancer, or acquired, such as somatic mutations that occur during the lifetime of an individual. Understanding the genetic basis of inherited risk of PDAC is essential to advancing patient care and outcomes through improved clinical surveillance, early detection initiatives, and targeted therapies. In this review we discuss factors associated with an increased risk of PDAC, the prevalence of genetic variants associated with an increased risk in patients with PDAC, estimates of PDAC risk in carriers of pathogenic germline variants in genes associated with an increased risk of PDAC. The role of common variants in pancreatic cancer risk will also be discussed.

Transfer Learning Reveals Cancer-Associated Fibroblasts Are Associated with Epithelial-Mesenchymal Transition and Inflammation in Cancer Cells in Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy characterized by an immunosuppressive tumor microenvironment enriched with cancer-associated fibroblasts (CAF). This study used a convergence approach to identify tumor cell and CAF interactions through the integration of single-cell data from human tumors with human organoid coculture experiments. Analysis of a comprehensive atlas of PDAC single-cell RNA sequencing data indicated that CAF density is associated with increased inflammation and epithelial-mesenchymal transition (EMT) in epithelial cells. Transfer learning using transcriptional data from patient-derived organoid and CAF cocultures provided in silico validation of CAF induction of inflammatory and EMT epithelial cell states. Further experimental validation in cocultures demonstrated integrin beta 1 (ITGB1) and vascular endothelial factor A (VEGFA) interactions with neuropilin-1 mediating CAF-epithelial cell cross-talk. Together, this study introduces transfer learning from human single-cell data to organoid coculture analyses for experimental validation of discoveries of cell-cell cross-talk and identifies fibroblast-mediated regulation of EMT and inflammation. SIGNIFICANCE: Adaptation of transfer learning to relate human single-cell RNA sequencing data to organoid-CAF cocultures facilitates discovery of human pancreatic cancer intercellular interactions and uncovers cross-talk between CAFs and tumor cells through VEGFA and ITGB1.

The Voice of Travel Nurses: Facilitating Effective Staffing During Pandemic and Expansion-Related Demands in a Children's Hospital.

OBJECTIVE: The aim of this study was to explore the experience and perceived value of travel nurses in a children's hospital. BACKGROUND: Children's hospitals face unique challenges related to highly specialized care requirements and workforce expansion limitations. Travel nurses can augment nurse staffing capacity during times of intense demand and may offer insights as organizations seek to strengthen work environments. METHODS: Pediatric travel nurses currently contracted at the hospital were invited to participate in a focus group or interview. Content analysis was used to summarize information and identify themes. RESULTS: From the 56 participants, 5 themes emerged. The themes were financial, flexibility, searching for healthy work environments, nursing care, and solutions. CONCLUSIONS: Hearing the voices of travel nurses may offer valuable feedback to strengthen future professional practice environments.

Community responses to persons with aphasia participating in CoActive therapeutic theatre: A pilot study.

BACKGROUND: Persons with aphasia (PWA) experience a number of communicative and social-emotional challenges. Reported experiences of PWA include but are not limited to, being misunderstood, isolated, frustrated, and infantilised. AIMS: The aim of this pilot study, involving a Life Participation Approach to Aphasia (LPAA), conducted over the course of 2 years, was to understand community perceptions of aphasia while PWA engaged in an interprofessional treatment program involving speech and drama therapy. METHODS & PROCEDURES: The interprofessional treatment program involved PWA participating in a therapeutic theatre program using the CoActive Therapeutic Theater (CoATT) while also receiving speech-language therapy. Each year, the PWA performed a different, original therapeutic theatre production for a public audience, at the culmination of their interprofessional treatment program. In this paper, we share data obtained from perspectives of audience members who witnessed the theatre production and aphasia education during the first year of the study and friends and family of PWA who participated in the therapeutic theatre process during the second year of the study. OUTCOMES & RESULTS: Responses from audience members who participated in aphasia education and witnessed the therapeutic theatre performance by the PWA during the first year, indicated an increased knowledge of aphasia. Friends and family members of PWA who witnessed their loved ones engaging in the CoATT process through interprofessional treatment, in the second year, reported that their loved ones benefited from the CoATT process, which was distinct from other therapeutic processes to their knowledge and that they were impacted by watching their loved one perform. CONCLUSIONS & IMPLICATIONS: These initial findings create footing towards understanding impact of therapeutic theatre in combination with speech-language therapy in the lives of PWA. They help us to obtain an initial appreciation of how therapeutic theatre and aphasia education help connect PWA and their community. WHAT THIS PAPER ADDS: What is already known on this subject Caregivers and communities at large play a significant role in and substantially impact the recovery of their loved ones (Dalemans et al., 2010; Grawburget et al., 2013; Kniepmann & Cupler, 2014) with aphasia. However, existing research suggests that persons with aphasia (PWA) are often misunderstood, isolated and infantilised by their communities. What this paper adds to existing knowledge The findings of our study reveal that friends, families and extended communities of PWA gain a positive and deep understanding of challenges experienced by PWA through therapeutic theatre supported by speech language therapy, based in a new CoActive Therapeutic Theatre (CoATT) model. This PWA community also agrees that therapeutic theatre in combination with speech-language therapy provides confidence and camaraderie between PWAs and strengthen connection between all constituencies. These results support the need for interprofessional intervention within the framework of a Life Participation Approach to Aphasia (LPAA). What are the potential or actual clinical implications of this work? Treatment paradigms that bring PWAs in contact with their communities using an LPAA approach can increase confidence and social engagement for PWAs potentially leading to better outcomes for their individual speech-language therapy as well as create means of educating communities about PWA, and their stories.

International evidence-based Kyoto guidelines for the management of intraductal papillary mucinous neoplasm of the pancreas.

This study group aimed to revise the 2017 international consensus guidelines for the management of intraductal papillary mucinous neoplasm (IPMN) of the pancreas, and mainly focused on five topics; the revision of high-risk stigmata (HRS) and worrisome features (WF), surveillance of non-resected IPMN, surveillance after resection of IPMN, revision of pathological aspects, and investigation of molecular markers in cyst fluid. A new development from the prior guidelines is that systematic reviews were performed for each one of these topics, and published separately to provide evidence-based recommendations. One of the highlights of these new "evidence-based guidelines" is to propose a new management algorithm, and one major revision is to include into the assessment of HRS and WF the imaging findings from endoscopic ultrasound (EUS) and the results of cytological analysis from EUS-guided fine needle aspiration technique, when this is performed. Another key element of the current guidelines is to clarify whether lifetime surveillance for small IPMNs is required, and recommends two options, "stop surveillance" or "continue surveillance for possible development of concomitant pancreatic ductal adenocarcinoma", for small unchanged BD-IPMN after 5 years surveillance. Several other points are also discussed, including identifying high-risk features for recurrence in patients who underwent resection of non-invasive IPMN with negative surgical margin, summaries of the recent observations in the pathology of IPMN. In addition, the emerging role of cyst fluid markers that can aid in distinguishing IPMN from other pancreatic cysts and identify those IPMNs that harbor high-grade dysplasia or invasive carcinoma is discussed.

The Role of Nurses in the Management of Adverse Events in Patients Receiving First-Line Axitinib Plus Immuno-Oncology Agents for Advanced Renal Cell Carcinoma.

OBJECTIVES: The recent approval of first-line tyrosine kinase inhibitor plus immuno-oncology agent combination therapy for the treatment of advanced renal cell carcinoma offers substantially improved response rates and survival compared with the previous standard of care. This expansion of treatment options has also led to a greater range and complexity of potential treatment-related adverse events related to overlapping toxicities. The aim of this article is to discuss the management of common treatment-emergent adverse events (AEs) associated with axitinib plus immuno-oncology therapy, highlight the specific roles of oncology nurses in managing these events, and provide AE management resources to aid oncology nurses in their care of patients with advanced renal cell carcinoma. DATA SOURCES: Author experience, journal articles, and treatment guidelines were used. CONCLUSION: The use of oncology nurses and nurse-led innovations to monitor and assess treatments can have a positive impact on the management of AEs in cancer patients by identifying those who are most at risk, providing regular assessment, appropriate patient education, and supporting the monitoring of patient safety. IMPLICATIONS FOR NURSING PRACTICE: Skilled oncology nurses should be a key part of a team that addresses the supportive care needs and management of AEs that are associated with novel cancer treatments. Early and ongoing communication between the patient and oncology nurses regarding the development of adverse events is a critical component of maximizing treatment outcomes and quality of life.

Three-dimensional assessments are necessary to determine the true, spatially-resolved composition of tissues.

Methods for spatially resolved cellular profiling using thinly cut sections have enabled in-depth quantitative tissue mapping to study inter-sample and intra-sample differences in normal human anatomy and disease onset and progression. These methods often profile extremely limited regions, which may impact the evaluation of heterogeneity due to tissue sub-sampling. Here, we applied CODA, a deep learning-based tissue mapping platform, to reconstruct the three-dimensional (3D) microanatomy of grossly normal and cancer-containing human pancreas biospecimens obtained from individuals who underwent pancreatic resection. To compare inter- and intra-sample heterogeneity, we assessed bulk and spatially resolved tissue composition in a cohort of two-dimensional (2D) whole slide images (WSIs) and a cohort of thick slabs of pancreas tissue that were digitally reconstructed in 3D from serial sections. To demonstrate the marked under sampling of 2D assessments, we simulated the number of WSIs and tissue microarrays (TMAs) necessary to represent the compositional heterogeneity of 3D data within 10% error to reveal that tens of WSIs and hundreds of TMA cores are sometimes needed. We show that spatial correlation of different pancreatic structures decay significantly within a span of microns, demonstrating that 2D histological sections may not be representative of their neighboring tissues. In sum, we demonstrate that 3D assessments are necessary to accurately assess tissue composition in normal and abnormal specimens and in order to accurately determine neoplastic content. These results emphasize the importance of intra-sample heterogeneity in tissue mapping efforts.

Power-law growth models explain incidences and sizes of pancreatic cancer precursor lesions and confirm spatial genomic findings.

Pancreatic ductal adenocarcinoma is a rare but lethal cancer. Recent evidence reveals that pancreatic intraepithelial neoplasms (PanINs), the microscopic precursor lesions in the pancreatic ducts that can give rise to invasive pancreatic cancer, are significantly larger and more prevalent than previously believed. Better understanding of the growth law dynamics of PanINs may improve our ability to understand how a miniscule fraction of these lesions makes the transition to invasive cancer. Here, using artificial intelligence (AI)-based three-dimensional (3D) tissue mapping method, we measured the volumes of >1,000 PanIN and found that lesion size is distributed according to a power law with a fitted exponent of -1.7 over > 3 orders of magnitude. Our data also suggest that PanIN growth is not very sensitive to the pancreatic microenvironment or an individual's age, family history, and lifestyle, and is rather shaped by general growth behavior. We analyze several models of PanIN growth and fit the predicted size distributions to the observed data. The best fitting models suggest that both intraductal spread of PanIN lesions and fusing of multiple lesions into large, highly branched structures drive PanIN growth patterns. This work lays the groundwork for future mathematical modeling efforts integrating PanIN incidence, morphology, genomic, and transcriptomic features to understand pancreas tumorigenesis, and demonstrates the utility of combining experimental measurement of human tissues with dynamic modeling for understanding cancer tumorigenesis.

Child Rights during the COVID-19 Pandemic: Learning from Child Health-and-Rights Professionals across the World.

The COVID-19 pandemic underscores the importance of a child rights-based approach to policymaking and crisis management. Anchored in the United Nations Convention on the Rights of the Child, the 3P framework-provision, protection, and participation-forms the foundation for health professionals advocating for children's rights. Expanding it with two additional domains-preparation and power-into a 5P framework has the potential to enhance child rights-based policies in times of crisis and future pandemics. The study aimed to (1) gather perspectives from child health-and-rights specialists on how children's rights were highlighted during the early phase of the pandemic in their respective settings; and (2) evaluate the usefulness of the 5P framework in assessing children's visibility and rights. A qualitative survey was distributed among child health-and-rights professionals; a total of 68 responses were analysed in Atlas.ti 9 from a multi-disciplinary group of policymakers and front-line professionals in eight world regions. As framed by the 5Ps, children's rights were generally not safeguarded in the initial pandemic response and negatively impacted children's health and wellbeing. Further, children lacked meaningful opportunities to raise their concerns to policymakers. The 5P framework holds the potential to shape an ethical child rights-based decision-making framework for future crises, both nationally and globally.

Three-dimensional analysis of ductular reactions and their correlation with liver regeneration and fibrosis.

The liver has multiple regeneration modes, including hepatocellular hypertrophy and self-renewal of hepatocytes. When hepatocyte proliferation is impaired, hepatic progenitor cells may proliferate through ductular reaction (DR), differentiate into hepatocytes, and contribute to fibrosis. However, the three-dimensional spatial relationship between DR and regenerating hepatocytes and dynamic changes in DR associated with fibrosis remain poorly understood. Here, we performed three-dimensional (3D) imaging of cleared 42 liver explants with chronic and acute liver diseases and 4 normal livers to visualize DR. In chronic hepatic liver diseases, such as viral hepatitis, steatohepatitis, autoimmune hepatitis, and cryptogenic cirrhosis, the total length and number of branches of DR showed a significant positive correlation. We studied the spatial relationship between DR and GS-expressing cells using glutamine synthetase (GS) and cytokeratin 19 (CK19) as markers of liver regeneration and DR, respectively. The percentage of CK19-positive cells that co-expressed GS was less than 10% in chronic liver diseases. In contrast, nearly one-third of CK19-positive cells co-expressed GS in acute liver diseases, and chronic cholestatic liver diseases, including primary biliary cholangitis and primary sclerosing cholangitis, showed no co-expression. We also found that DR was longer and had more branching in livers with progressive fibrosis compared to those with regressive fibrosis. Our results suggest that DR displays varying degrees of spatial complexity and contribution to liver regeneration. DR may serve as hepatobiliary junctions that maintain continuity between hepatocytes and bile ducts rather than hepatocyte regeneration in chronic liver diseases.

Avelumab First-Line Maintenance Therapy: Managing Patients With Advanced Urothelial Carcinoma.

BACKGROUND: The phase 3 of JAVELIN Bladder 100 trial demonstrated that avelumab first-line (1L) maintenance in addition to best supportive care significantly prolonged overall survival compared to best supportive care alone. It is now the standard of care for platinum-eligible patients with locally advanced or metastatic urothelial carcinoma that has not progressed with 1L platinum-containing chemotherapy. OBJECTIVES: This article provides considerations for oncology nurses to effectively implement avelumab 1L maintenance treatment in the clinical setting. METHODS: This article reviews clinical evidence and implications for oncology nurses caring for patients receiving avelumab 1L maintenance treatment. FINDINGS: Oncology nurses can provide comprehensive care for patients with advanced urothelial carcinoma and ensure the safe and appropriate use of avelumab 1L maintenance treatment by educating patients and caregivers, ensuring correct administration, and promptly recognizing and managing immune-related adverse events.

Inpatient Screening for Early Identification of Developmental Risk in Infants with Congenital Heart Defects.

OBJECTIVE: To assess the utility of an inpatient standardized developmental screener for early identification of developmental risk in infants with a congenital heart defect (CHD). STUDY DESIGN: This was a retrospective, observational study with convenience sample of postoperative infants with CHD (aged 3-12 months) who underwent neurodevelopmental screening with the Bayley Scales of Infant and Toddler Development Screening Test, Third Edition (Bayley-III Screener) just before discharge. Follow-up testing included outpatient Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) (12-42 mo). RESULTS: The Bayley-III Screener was administered to 325 infants at a median of 5 months, 8 days (IQR 3 months, 28 days, to 7 months, 17 days). Infants scored below age expectations on the Gross Motor (79%), Fine Motor (63%), Receptive Communication (50%), Expressive Communication (38%), and Cognitive (38%) domains. In each domain, children with CHD had greater rates of scores below expectations than the normative sample (each P <.001). The odds of scoring in a greater risk category were increased for infants with genetic syndromes and longer length of hospital stay across all domains. The outpatient Bayley-III (n = 74, 23% follow-up) was completed at a median of 19 months, 9 days (IQR: 17 months, 3 days, to 23 months, 37 days). Individuals falling in greater-risk categories on their initial Bayley-III Screener were significantly more likely to have worse performance on their follow-up outpatient Bayley-III (each domain P < .01). CONCLUSIONS: Inpatient standardized neurodevelopmental screening provides important clinical utility in identifying infants at risk for developmental concern, allows for provision of recommendations for developmental services, and potentially overcomes barriers often noted in returning for outpatient post-discharge assessments.
