2%) patients. In the univariate analysis, the mean age of the ECMO group was lower, ADL function before onset was more favorable, mean body weight was higher, and the mean interval from onset until hospital arrival was shorter than those in the non-ECMO group. One-to 3-month survival or favorable cerebral function outcome rates were higher in the ECMO group than in the non-ECMO group. In the multivariate analysis, ECMO use and the interval from onset until hospital arrival were independent prognostic factors for favorable cerebral functional outcomes at 1 and 3&nbsp;months. CONCLUSION E-CPR may be associated with favorable outcomes in carefully selected patients with nonshockable OHCA. BACKGROUND Pulmonary embolism (PE) is a very common presentation in the emergency department (ED). Despite being life-threatening, PE is preventable if diagnosed and managed early, especially in high-risk patients like pediatric oncology patients. A negative d-dimer has a high negative predictive value and can rule out PE in low-risk patients; however, it does not lower post-test probability enough and should be coupled with further diagnostics in high-risk patients. CASE REPORT We describe the case of a 14-year-old girl known to have acute lymphoblastic leukemia and presented to the ED with persistent nausea and vomiting only, which was exacerbated by exertion. She had previously presented to the ED 1&nbsp;week earlier for the same complaint, with a nonrevealing physical examination. At that time, the patient was worked up for nausea and vomiting and received symptomatic treatment. An electrocardiogram (ECG) during that presentation showed normal sinus rhythm. During this presentation, ECG showed new ST segment depressions from V1 to V6 in addition to an S1Q3T3 pattern. This, coupled with the exacerbation of her initial symptoms, triggered further investigations. Computed tomography angiography (CTA) of the chest was performed and showed a right lower lobe segmental pulmonary artery embolus. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? This case highlights the importance of having a high level of suspicion for PE, especially in pediatric oncology patients and specifically in hematologic malignancies. Although our patient's presentation, examination, and laboratory results were not concerning initially, CTA of the chest showed a PE. We are addressing this particular topic to increase the awareness of emergency physicians of cases like this, as PE can have an unusual presentation and missing such a diagnosis can be fatal. BACKGROUND Zipper injuries are rare in the pediatric emergency department, with most reported cases involving the penile and scrotal skin. Knowledge of appropriate zipper release techniques is important to ensure safe and immediate removal of entrapped tissue to prevent complications. CASE REPORT This case report describes a unique presentation of a zipper injury involving entrapment of the upper eyelid. We describe the successful removal of the zipper with gentle manipulation aided by mineral oil lubrication and by cutting fabric from the zipper system to release tension. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? While zipper injuries are rare, an emergency physician must be prepared to provide urgent intervention to prevent complications. This unique case report presents 1 example of successful zipper release in the case of a zipper injury to the eyelid in a child.

BACKGROUND Radiation-induced skin injury is a serious concern during radiotherapy and radiation accidents. Skin fat represents the dominant architectural component of the human skin. However, the interplay between skin fat and the progression of radiation-induced skin injury remains largely unexplored. OBJECTIVE This study aims to elucidate the interplay between skin fat and the progression of radiation-induced skin injury. METHODS SD rats were irradiated with an electron beam. mRNA profiles were determined by RNA-Seq. The skin lipid mass was monitored by magnetic resonance imaging (MRI) and lipid profiles were measured by liquid chromatography-mass spectrometry (LC-MS). Human mature adipocytes isolated from dermal and subcutaneous white adipose tissues (WATs) were co-cultured with human keratinocytes (HaCaT) and skin fibroblasts (WS1) in the transwell culture system. Cell migration ability was measured by migration assay. RESULTS Radiation modulated cutaneous lipid metabolism by downregulating multiple pathways. Moreover, radiation decreased skin fat mass with altered lipid metabolite profiles. The rats fed with a high-fat diet showed resistance to radiogenic skin injury compared with that with a control diet, indicating that skin lipid plays a radioprotective role. Mature adipocytes promoted the migration but not the proliferation of co-cultured skin keratinocytes and fibroblasts. Palmitic acid, the most abundant fatty acid in skin tissues, facilitated the migration of WS1 cells. Moreover, fatty acid-binding protein 4 (FABP4) could be incorporated into skin cells and promote DNA damage repair in irradiated skin fibroblasts. CONCLUSION Radiation induces cutaneous lipid remolding, and skin adipocytes confer a protective role against radiation-induced skin injury. BACKGROUND NUAK2 is a critical gene that participates in the carcinogenesis of various types of cancers including melanomas. However, the expression patterns of NUAK2 in normal skin and in various types of skin tumors have not been fully elucidated to date. OBJECTIVES To elucidate the distribution and localization of NUAK2 expression in normal skin, and characterize the expression patterns of NUAK2 and YAP in various types of skin tumors. METHODS In this study, we characterized the expression of NUAK2 in tissues by developing a novel NUAK2-specific monoclonal antibody and using that to determine NUAK2 expression patterns in normal skin and in 155 cases of various types of skin tumors, including extramammary Paget's disease (EMPD), squamous cell carcinoma (SCC), Bowen's disease (BD), actinic keratosis (AK), basal cell carcinoma (BCC) and angiosarcoma (AS). Further, we analyzed the expression patterns of YAP and p-Akt in those tumors. RESULTS Our analyses revealed that NUAK2 is expressed at high frequencies in EMPD, SCC, BD, AK, BCC and AS.
