RESUMO
BACKGROUND: Gastrostomy tubes (G-tubes) are invaluable clinical tools that play a role in palliation and nutrition in patients with cancer. This study aimed to better understand the risks and benefits associated with the placement and maintenance of G-tubes. METHODS: Patients who underwent placement of a G-tube for cancer from January 2013 through December 2017 at a tertiary care center were considered for inclusion. Clinical data were retrospectively collected from medical records. RESULTS: A total of 242 patients with cancer, whose average age at diagnosis was 61 years (range, 21-94 years), underwent G-tube placement for nutrition (76.4%), decompression (22.7%), or both (0.8%). Successful insertion was achieved in 96.8%, but 8 patients required >1 attempted method of insertion. In the decompression group, minor postplacement complications were less common (23.6% vs 53.5%; P<.001) and survival was shorter (P<.001) compared with the nutrition group. For those with decompressive G-tubes, 45.5% had a palliative care consult; 56.4% were seen by social workers; and 46.3% went to hospice. The frequency of hospice discharge was higher in patients who had consults (53.7% vs 23.1%; P=.01). CONCLUSIONS: Half of the patients who received decompressive G-tubes presented with stage IV disease and died within 1 month of placement. Those with >1 consult were more likely to be discharged to hospice. Patients with G-tubes for nutrition saw no change in functionality, complication rate, or survival, regardless of adjunct chemotherapy status. These findings illustrate the need for a tool to allow a better multidisciplinary approach and interventional decision-making for patients with cancer.

The receptor for hyaluronic acid-mediated motility (RHAMM) is upregulated in various cancers. We previously screened genes upregulated in human hepatocellular carcinomas for their metastatic function in a mouse model of pancreatic neuroendocrine tumor (PNET) and identified that human RHAMMB promoted liver metastasis. It was unknown whether RHAMMB is upregulated in pancreatic cancer or contributes to its progression. In this study, we found that RHAMM protein was frequently upregulated in human PNETs. We investigated alternative splicing isoforms, RHAMMA and RHAMMB, by RNA-Seq analysis of primary PNETs and liver metastases. RHAMMB, but not RHAMMA, was significantly upregulated in liver metastases. RHAMMB was crucial for in vivo metastatic capacity of mouse and human PNETs. RHAMMA, carrying an extra 15-amino acid-stretch, did not promote metastasis in spontaneous and experimental metastasis mouse models. Moreover, RHAMMB was substantially higher than RHAMMA in pancreatic ductal adenocarcinoma (PDAC). RHAMMB, but not RHAMMA, correlated with both higher EGFR expression and poorer survival of PDAC patients. Knockdown of EGFR abolished RHAMMB-driven PNET metastasis. Altogether, our findings suggest a clinically relevant function of RHAMMB, but not RHAMMA, in promoting PNET metastasis in part through EGFR signaling. RHAMMB can thus serve as a prognostic factor for pancreatic cancer.

INTRODUCTION: Clinical clearance of a child's cervical spine after trauma is often challenging because of impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) is the criterion standard for excluding ligamentous injury in children but is constrained by long image acquisition times and frequent need for anesthesia. Limited-sequence magnetic resonance imaging (LSMRI) is used in evaluating the evolution of traumatic brain injury and may also be useful for cervical spine clearance while potentially avoiding the need for anesthesia. The purpose of this study was to assess the sensitivity and negative predictive value of LSMRI as compared with criterion standard full-sequence MRI as a screening tool to rule out clinically significant ligamentous cervical spine injury. METHODS: We conducted a 10-center, 5-year retrospective cohort study (2017-2021) of all children (0-18 years) with a cervical spine MRI after blunt trauma. Magnetic resonance imaging images were rereviewed by a study pediatric radiologist at each site to determine if the presence of an injury could be identified on limited sequences alone. Unstable cervical spine injury was determined by study neurosurgeon review at each site. RESULTS: We identified 2,663 children younger than 18 years who underwent an MRI of the cervical spine with 1,008 injuries detected on full-sequence studies. The sensitivity and negative predictive value of LSMRI were both >99% for detecting any injury and 100% for detecting any unstable injury. Young children (younger than 5 years) were more likely to be electively intubated or sedated for cervical spine MRI. CONCLUSION: Limited-sequence magnetic resonance imaging is reliably detects clinically significant ligamentous injury in children after blunt trauma. To decrease anesthesia use and minimize MRI time, trauma centers should develop LSMRI screening protocols for children without a reliable neurologic examination. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.

An unacceptable inequity exists in the burden of pediatric surgical disease and access to surgical and anesthesia care between low- and middle-income countries (LMIC) and high-income countries (HIC). Civil society organizations (CSOs) and the voluntary sector have been integral in addressing this imbalance. This article summarizes the roles that these organizations have played in improving pediatric surgical care globally and how their roles have evolved over the years. CSOs and voluntary organizations have historically provided operations on LMIC patients; however, the focus has shifted to building sustainable surgical systems by training a skilled workforce, improving local infrastructure, and contributing to research and advocacy efforts.

BACKGROUND: This prospective observational cohort study evaluates risk-stratified venous thromboembolism (VTE) screening in injured children. While the reported incidence of VTE is 6% to 10% among critically injured children, there is no standard for screening. Venous thromboembolism may have long-term sequelae in children, including postthrombotic syndrome. METHODS: Patients admitted to a level 1 pediatric trauma center were risk stratified for VTE using a validated prediction algorithm. Children at high risk (risk scores ≥523; i.e., ≥1% risk) received screening duplex ultrasonography. Children at moderate risk (risk scores 410-522; i.e., 0.3-0.99% risk) were screened as a comparison/control. RESULTS: Three-hundred fifty-five children were consecutively risk stratified from October 2019 to May 2021. Forty-seven children received screening duplex ultrasounds: 21 from a high-risk cohort and 26 from a moderate-risk cohort. Four children were diagnosed with VTE in the high-risk cohort compared with seven in the moderate-risk cohort ( p = 0.53). Total incidence of VTE among screened children was 23.4% (11 of 47). Asymptomatic VTE accounted for 81.8% of all events (9 of 11). Fifty-four percent (6 of 11) of VTE were central venous catheter associated. Venous thromboembolism in surviving children resolved by 3 to 6 months with no symptoms of postthrombotic syndrome after 1 year. No cases of VTE were identified in unscreened children, yielding an institutional VTE incidence of 3.1% (11 of 355). DISCUSSION: Risk-stratified screening demonstrates a significant incidence of asymptomatic VTE in injured children. These results may guide reevaluation of prediction algorithms developed from symptomatic VTE risk and longitudinal study of the sequelae of asymptomatic VTE. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

BACKGROUND: The role of emergency department resuscitative thoracotomy (EDT) in traumatically injured children has not been elucidated. We aimed to perform a systematic review and create evidence-based guidelines to answer the following PICO (population, intervention, comparator, and outcome) question: should pediatric patients who present to the emergency department pulseless (with or without signs of life [SOL]) after traumatic injuries (penetrating thoracic, penetrating abdominopelvic, or blunt) undergo EDT (vs. no EDT) to improve survival and neurologically intact survival? METHODS: Using Grading of Recommendations Assessment, Development and Evaluation methodology, a group of 12 pediatric trauma experts from the Pediatric Trauma Society, Western Trauma Association, and Eastern Association for the Surgery of Trauma assembled to perform a systematic review. A consensus conference was conducted, a database was queried, abstracts and manuscripts were reviewed, data extraction was performed, and evidence quality was determined. Evidence tables were generated, and the committee voted on guideline recommendations. RESULTS: Three hundred three articles were identified. Eleven studies met the inclusion criteria and were used for guideline creation, providing 319 pediatric patients who underwent EDT. No data were available on patients who did not undergo EDT. For each PICO, the quality of evidence was very low based on the serious risk of bias and serious or very serious imprecision. CONCLUSION: Based on low-quality data, we make the following recommendations. We conditionally recommend EDT when a child presents pulseless with SOL to the emergency department following penetrating thoracic injury, penetrating abdominopelvic injury and after blunt injury if emergency adjuncts point to a thoracic source. We conditionally recommend against EDT when a pediatric patient presents pulseless without SOL after penetrating thoracic and penetrating abdominopelvic injury. We strongly recommend against EDT in the patient without SOL after blunt injury.

BACKGROUND: A paucity of data exists with regard to the incidence, management, and outcomes of venous thromboembolism (VTE) in injured children. We sought to determine the impact of institutional chemoprophylaxis guidelines on VTE rates in a pediatric trauma population. METHODS: A retrospective review of injured children (≤15 years) admitted between 2009 and 2018 at 10 pediatric trauma centers was performed. Data were gathered from institutional trauma registries and dedicated chart review. The institutions were surveyed as to whether they had chemoprophylaxis guidelines in place for high-risk pediatric trauma patients, and outcomes were compared based on the presence of guidelines using χ 2 analysis ( p < 0.05). RESULTS: There were 45,202 patients evaluated during the study period. Three institutions (28,359 patients, 63%) had established chemoprophylaxis policies during the study period ("Guidelines"); the other seven centers (16,843 patients, 37%) had no such guidelines ("Standard"). There were significantly lower rates of VTE in the Guidelines group, but these patients also had significantly fewer risk factors. Among critically injured children with similar clinical presentations, there was no difference in VTE rate. Specifically within the Guidelines group, 30 children developed VTE. The majority (17/30) were actually not indicated for chemoprophylaxis based on institutional guidelines. Still, despite protocols only one VTE patient in the guidelines group who was indicated for intervention ended up receiving chemoprophylaxis prior to diagnosis. No consistent ultrasound screening protocol was in place at any institution during the study. CONCLUSION: The presence of an institutional policy to guide chemoprophylaxis for injured children is associated with a decreased overall frequency of VTE, but this disappears when controlling for patient factors. However, the overall efficacy is impacted by a combination of deficits in guideline compliance and structure. Further prospective data are needed to help determine the ideal role for chemoprophylaxis and protocols in pediatric trauma. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

The contemporary pillars of congenital diaphragmatic hernia (CDH) management include prenatal diagnosis for multidisciplinary care coordination and counseling, medical optimization after birth, and elective (not emergent) operative repair after stabilization, allowing for improvement in pulmonary hypertension and maturation of lungs. Lung hypoplasia and pulmonary hypertension in infants with CDH represent a medical emergency, not one that necessitates immediate surgery. Many infants surviving CDH repair have significant morbidities that may persist into adulthood. Rare cases of previously occult CDH may present acutely in the older child or adult with nonspecific gastrointestinal or pulmonary symptoms.
