Glioblastoma (GBM) is the most common malignant primary brain tumor in adults. Despite an established standard of care including surgical resection, radiation therapy, and chemotherapy, GBM unfortunately is associated with a dismal prognosis. Therefore, researchers are extensively evaluating avenues to expand GBM therapy and improve outcomes in patients with GBM. In this review, we provide a broad overview of novel GBM therapies that have recently completed or are actively undergoing study in clinical trials. These therapies expand across medical, surgical, and radiation clinical trials. We additionally review methods for improving clinical trial design in GBM.

This is the first clinical practice guideline (CPG) from the American Academy of Pediatrics outlining evidence-based approaches to safely prescribing opioids for acute pain in outpatient settings. The central goal is to aid clinicians in understanding when opioids may be indicated to treat acute pain in children and adolescents and how to minimize risks (including opioid use disorder, poisoning, and overdose). The document also seeks to alleviate disparate pain treatment of Black, Hispanic, and American Indian/Alaska Native children and adolescents, who receive pain management that is less adequate and less timely than that provided to white individuals. There may also be disparities in pain treatment based on language, socioeconomic status, geographic location, and other factors, which are discussed. The document recommends that clinicians treat acute pain using a multimodal approach that includes the appropriate use of nonpharmacologic therapies, nonopioid medications, and, when needed, opioid medications. Opioids should not be prescribed as monotherapy for children or adolescents who have acute pain. When using opioids for acute pain management, clinicians should prescribe immediate-release opioid formulations, start with the lowest age- and weight-appropriate doses, and provide an initial supply of 5 or fewer days, unless the pain is related to trauma or surgery with expected duration of pain longer than 5 days. Clinicians should not prescribe codeine or tramadol for patients younger than 12 years; adolescents 12 to 18 years of age who have obesity, obstructive sleep apnea, or severe lung disease; to treat postsurgical pain after tonsillectomy or adenoidectomy in patients younger than 18 years; or for any breastfeeding patient. The CPG recommends providing opioids when appropriate for treating acutely worsened pain in children and adolescents who have a history of chronic pain; clinicians should partner with other opioid-prescribing clinicians involved in the patient’s care and/or a specialist in chronic pain or palliative care to determine an appropriate treatment plan. Caution should be used when treating acute pain in those who are taking sedating medications. The CPG describes potential harms of discontinuing or rapidly tapering opioids in individuals who have been on stable, long-term opioids to treat chronic pain. The guideline also recommends providing naloxone and information on naloxone, safe storage and disposal of opioids, and direct observation of medication administration. Clinicians are encouraged to help caregivers develop a plan for safe disposal. The CPG contains 12 key action statements based on evidence from randomized controlled trials, high-quality observational studies, and, when studies are lacking or could not feasibly or ethically be conducted, from expert opinion. Each key action statement includes a level of evidence, the benefit-harm relationship, and the strength of recommendation.

AbstractPrior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5‐year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included. Seasons were defined as: Northern Hemisphere—winter (December–February); spring (March–May); summer (June–August); autumn (September–November) and Southern Hemisphere—winter (June–August); spring (September–November); summer (December–February); autumn (March–May). Additional outcomes included the mean temperature in months with and without an iTTP episode at each site. A total of 583 patients experienced 719 iTTP episodes. The observed proportion of iTTP episodes during the winter was significantly greater than expected if equally distributed across seasons (28.5%, 205/719, 25.3%–31.9%; p = .03). Distance from the equator and mean temperature deviation both positively correlated with the proportion of iTTP episodes during winter. Acute iTTP episodes were associated with the winter season and colder temperatures, with a second peak during summer. Occurrence during winter was most pronounced at sites further from the equator and/or with greater annual temperature deviations. Understanding the etiologies underlying seasonal patterns of disease may assist in discovery and development of future preventative therapies and inform models for resource utilization.

Leptomeningeal disease (LMD) is a devastating sequelae of metastatic spread that affects approximately 5% of cancer patients. The incidence of LMD is increasing due to advancements in systemic therapy and enhanced detection methods. The purpose of this review is to provide a detailed overview of the evidence in the detection, prognostication, and treatment of LMD. A comprehensive literature search of PUBMED was conducted to identify articles reporting on LMD including existing data and ongoing clinical trials. We found a wide array of treatment options available for LMD including chemotherapy, targeted agents, and immunotherapy as well as several choices for radiotherapy including whole brain radiotherapy (WBRT), stereotactic radiosurgery (SRS), and craniospinal irradiation (CSI). Despite treatment, the prognosis for patients with LMD is dismal, typically 2–4 months on average. Novel therapies and combination approaches are actively under investigation with the aim of improving outcomes and quality of life for patients with LMD. Recent prospective data on the use of proton CSI for patients with LMD have demonstrated its potential survival benefit with follow-up investigations underway. There is a need for validated metrics to predict prognosis and improve patient selection for patients with LMD in order to optimize treatment approaches.

Oral health is an essential component of overall health for all individuals. The oral health of children and youth with developmental disabilities (CYDD) involves unique characteristics and needs of which pediatricians and pediatric clinicians can be aware. Risk for oral disease in CYDD is multifactorial and includes underlying medical conditions, medications, and ability to participate in preventive oral health care and treatment, and lack of access to providers is common for this population despite being eligible for Medicaid. Pediatric clinicians are uniquely positioned to support the oral health needs of CYDD and their families through the medical home. This clinical report aims to inform pediatric clinicians about the unique oral health needs of CYDD. It provides guidance on assessing caries risk and periodontal status using structured screening instruments; understanding dental trauma, the role of diet and caries risk, trauma prevention, and malocclusion; and providing anticipatory guidance on oral hygiene that includes tooth brushing, use of fluoridated toothpaste, assessing community water fluoridation, advocating for a dental home by 1 year of age, and transition to adult dental care as part of adolescent health care. It also highlights special considerations for dental treatment rendered under sedation or general anesthesia that CYDD may need. Pediatric clinicians can help reduce risk of CYDD developing dental disease by understanding the unique needs of their patients and their barriers to accessing oral health care in their community, communicating with the child’s dental home, and advocating for safe and accessible dental procedures.

Background: Extracranial metastases occur in <2% of cases of glioblastoma (GBM). When metastases do occur, bone is the most common destination. Herein, we review clinical characteristics of GBM patients with osseous metastases and evaluate both potential risk factors and prognostic significance. Methods: Using an institutional database, we identified and retrospectively analyzed 6 patients with both GBM and osseous metastases. We collected data on patient demographics, tumor genetics, clinical courses, and outcomes. Given the rarity of metastatic GBM, we conducted historical comparisons using previously published literature. Results: Five patients with osseous metastases (83%) were male, with a median age of 46 years at GBM diagnosis (range: 20–84). All patients had IDH -wildtype, MGMT promoter unmethylated GBM and 5 (83%) had alterations in TP53 . All patients underwent surgical resection for GBM followed by radiation with concurrent and adjuvant temozolomide. Four patients (67%) received bevacizumab prior to bone metastasis diagnosis. Bone metastases were discovered at a median of 12.2 months (range: 5.3–35.2) after GBM diagnosis and 4.8 months after starting bevacizumab (range: 3.5–13.2). Three patients (50%) received immunotherapy. After osseous metastasis diagnosis, the median survival was 25 days (range: 13–225). Conclusion: In our cohort, most patients were male and young at the time of GBM diagnosis. All patients had IDH -wildtype, MGMT promoter unmethylated GBM, and most had alterations in TP53 , which may be important for osseous metastasis. Most patients received bevacizumab, which has been associated with earlier metastasis. Osseous metastases of GBM occur and portend a dismal prognosis in an already aggressive malignancy.

TPS1647 Background: The majority of patients with primary and secondary central nervous system (CNS) malignancy develop cognitive impairment, fatigue, and mood-related symptoms. Radiotherapy has been shown to contribute to symptom burden often limiting quality of life and functional status. The development of interventions mitigating neurocognitive toxicity requires an accurate assessment of function and symptom burden. Formal neuropsychological evaluation is resource and time intensive, and often challenging to incorporate in routine clinical practice. There is a critical need to accurately assess cognition without causing undue burden to cancer patients while evaluating the efficacy of interventions that can be scaled and implemented at a population level. Methods: To adequately assess the neurocognitive function and related symptoms in patients with CNS malignancy we have designed an open-label decentralized clinical trial that will randomize patients who received intracranial radiation for primary or metastatic brain tumors in a 1:1 allocation to a therapy targeting radiation-related toxicity (metformin shipped to patient home) plus health promotion with a wearable device vs. health promotion with a wearable device alone. Participants will be stratified based on tumor type (glioblastoma vs. other glioma vs. brain metastases vs. meningioma) and age (<70 vs. 70+ years). Participants will be provided a wearable device for monitoring health status. Participants will undergo serial remote cognitive assessments with the Mayo Test Development Through Rapid Iteration, Validation and Expansion platform (Mayo Test Drive). Remote reported symptom collection via patient surveys and remote neurologic examination by telehealth will also be incorporated. Cognitive assessments and symptom surveys will be designed for completion on a smartphone, tablet, or computer device. Health data will be collected from the wearable device, including the number of steps per day and sleep quality/duration. Participants receiving metformin will utilize device apps to report medication adherence and adverse events. Study-related laboratory assessments will be completed remotely and transmitted electronically. This decentralized clinical trial will provide real-world cognitive and quality-of-life data for patients with primary and metastatic brain tumors while providing preliminary data on the effectiveness of device-based health promotion with or without metformin for treating radiation-related cognitive decline. Results gained from this study will guide future trials in neuro-oncology and other fields. This study is expected to open in March 2024.

Abstract Background Delirium is a common complication of older people in hospitals, rehabilitation and long-term facilities. Objective To assess the worldwide use of validated delirium assessment tools and the presence of delirium management protocols. Design Secondary analysis of a worldwide one-day point prevalence study on World Delirium Awareness Day, 15 March 2023. Setting Cross-sectional online survey including hospitals, rehabilitation and long-term facilities. Methods Participating clinicians reported data on delirium, the presence of protocols, delirium assessments, delirium-awareness interventions, non-pharmacological and pharmacological interventions, and ward/unit-specific barriers. Results Data from 44 countries, 1664 wards/units and 36 048 patients were analysed. Validated delirium assessments were used in 66.7% (n = 1110) of wards/units, 18.6% (n = 310) used personal judgement or no assessment, and 10% (n = 166) used other assessment methods. A delirium management protocol was reported in 66.8% (n = 1094) of wards/units. The presence of protocols for delirium management varied across continents, ranging from 21.6% (on 21/97 wards/units) in Africa to 90.4% (235/260) in Australia, similar to the use of validated delirium assessments with 29.6% (29/98) in Africa to 93.5% (116/124) in North America. Wards/units with a delirium management protocol [n = 1094/1664, 66.8%] were more likely to use a validated delirium test than those without a protocol [odds ratio 6.97 (95% confidence interval 5.289–9.185)]. The presence of a delirium protocol increased the chances for valid delirium assessment and, likely, evidence-based interventions. Conclusion Wards/units that reported the presence of delirium management protocols had a higher probability of using validated delirium assessments tools to assess for delirium.
