    Abstract Back pain is common, in up to 30% of children, increasing with age. Eighty percent is benign, mechanical type, improving within 2 weeks of conservative care. Required for those not improving is in-depth evaluation, including MRI, laboratory, and peer consultations. Spondylolysis and spondylolisthesis comprise almost 10% of pediatric back pain, often caused by lumbar hyperextension activities and treated conservatively in most cases. Osteoid osteomas and osteoblastomas constitute the most common benign spinal tumors in childhood. Aggressive and malignant tumors of the spine are rare but when present require tertiary care referral and a comprehensive oncology team for optimal life-sustaining outcomes.

    Abstract Introduction: Pediatric humeral lateral condyle fractures are the second most common elbow fractures. Their treatment presents challenges due to physeal and intra-articular involvement. Postoperative stiffness is a common concern that can limit limb functionality. This study aims to identify risk factors for postoperative stiffness in a large cohort of these fractures across multiple institutions.
    Methods: A large, multicenter retrospective review of medical records from 6 level I trauma centers was conducted. Data from children aged 1 to 12 years with lateral condyle fractures treated between 2005 and 2019 were collected. Elbow stiffness was defined in the present study as having a limited elbow ROM that led to requiring a physical or occupational therapy referral or needing surgical treatment to address stiffness. Relevant patient demographics, fracture characteristics, treatment approaches, and complications were analyzed.
    Results: Six hundred sixty-five fractures were analyzed. The average patient age was 8.8 years with 21% experiencing stiffness. The stiffness group had older patients, a higher incidence of elbow dislocations, a higher rate of open reduction, and more severe fracture patterns. Multivariate regression analysis identified open reduction, increased age, and concurrent elbow dislocation as significant risk factors for stiffness. Patients with stiffness commonly utilized only physical or occupational therapy (96%), while a small percentage (4%) required surgical interventions.
    Conclusions: This study highlights the risk factors for postoperative stiffness in pediatric humeral lateral condyle fractures, namely increased age, concomitant elbow dislocation, and treatment with open reduction. Families of older patients or severe fracture patterns requiring open reduction and those with concurrent elbow instability should be counseled about their increased risk of stiffness. The authors recommend initially attempting a closed reduction in high-risk patients to help mitigate the risk of postoperative stiffness. Early initiation of range of motion exercises may also be beneficial for at-risk patients.
    Level of evidence: Level III: Therapeutic studies-Investigating the results of treatment.

    Abstract Objectives: Many bacterial species naturally take up DNA from their surroundings and recombine it into their chromosome through homologous gene transfer (HGT) to aid in survival and gain advantageous functions. Herein we present the first characterization of Type IV pili facilitated natural competence in Fusobacterium nucleatum, which is a Gram-negative, anaerobic bacterium that participates in a range of infections and diseases including periodontitis, preterm birth, and cancer.
    Methods: Here we used bioinformatics on multiple Fusobacterium species, as well as molecular genetics to characterize natural competence in strain F. nucleatum subsp. nucleatum ATCC 23726.
    Results: We bioinformatically identified components of the Type IV conjugal pilus machinery and show this is a conserved system within the Fusobacterium genus. We next validate Type IV pili in natural competence in F. nucleatum ATCC 23726 and show that gene deletions in key components of pilus deployment (pilQ) and cytoplasmic DNA import (comEC) abolish DNA uptake and chromosomal incorporation. We next show that natural competence may require native F. nucleatum DNA methylation to bypass restriction modification systems and allow subsequent genomic homologous recombination.
    Conclusions: In summary, this proof of principle study provides the first characterization of natural competence in Fusobacterium nucleatum and highlights the potential to exploit this DNA import mechanism as a genetic tool to characterize virulence mechanisms of an opportunistic oral pathogen.

    Abstract Background: Diagnosis of
    Methods: We collected an additional urine specimen among individuals enrolling in an ongoing clinical trial at the Massachusetts General Hospital Sexual Health Clinic who presented with symptoms of urethritis or cervicitis (urethral or vaginal discharge, dysuria, or dyspareunia). We then assessed thermal, detergent, and combination DNA extraction conditions, varying the duration of heat at 95°C and concentration of Triton X. We assessed the efficacy of the various DNA extraction methods by quantitative polymerase chain reaction (qPCR). Once an extraction method was selected, we incubated samples for 90 minutes to permit isothermal recombinase polymerase amplification. We then assessed the performance of lateral flow Cas13a-based detection using our previously designed
    Results: We assessed DNA extraction conditions on 3 clinical urine specimens. There was no consistent significant difference in copies per microliter of DNA obtained using more or less heat. On average, we noted that 0.02% triton combined with 5 minutes of heating to 95°C resulted in the highest DNA yield, however, 0.02% triton alone resulted in a quantity of DNA that was above the previously determined analytic sensitivity of the assay. Given that detergent-based extraction is more easily deployable, we selected that as our method for extraction. We treated 23 clinical specimens with 0.02% triton, which we added to the Cas13a detection system. We ran all lateral flow detections in duplicate. The Cas13a-based assay detected 8 of 8 (100%) positive specimens, and 0 of 15 negative specimens.
    Conclusion: Using point-of-care DNA extraction, isothermal amplification, and Cas13a-based detection, our point-of-care lateral flow

    Abstract Coronary artery fistulas are uncommon but clinically important entities that may produce symptoms and significant complications such as angina, myocardial infarction, coronary artery aneurysm formation, and congestive heart failure. Multiple fistula types have been recognized, and classification uses factors such as etiology, coronary artery origin, and drainage site. Both invasive and noninvasive imaging play an important role in the management and treatment of these patients, and often times, more than one modality is necessary for comprehensive evaluation of coronary fistulas. Recent advances in both functional and anatomic imaging will likely also play a growing role in fistula evaluation. The purpose of this article is to review the classification, pathophysiology, clinical presentations, imaging findings, treatment, and future imaging directions of coronary artery fistulas.

    Abstract Background: The volume of remote monitoring (RM) data generates a significant workload and is generally dealt with by clinic staff during standard office hours, potentially delaying clinical action.
    Objective: The purpose of this study was to determine the clinical efficiency and workflow of implementing intensive RM (IRM) in patients with cardiac implantable electronic device (CIED) when compared with standard RM (SRM).
    Methods: From a cohort of >1500 remotely monitored devices, 70 patients were randomly selected to undergo IRM. For comparison, an equal number of matched patients were prospectively selected for SRM. Intensive follow-up occurred via automated vendor-neutral software with rapid alert processing by International Board of Heart Rhythm Examiners-certified device specialists. Standard follow-up was conducted by clinic staff during office hours via individual device vendor interfaces. Alerts were categorized on the basis of the level of acuity as actionable (red [high], yellow [moderate]), or green [not requiring action]).
    Results: Over 9 months of follow-up, 922 remote transmissions were received; 339 (36.8%) were coded as actionable alerts (118 in IRM and 221 in SRM;
    Conclusion: Intensive and managed RM results in a significant reduction in time to review alerts and number of actionable alerts. Monitoring with enhanced alert adjudication is needed to facilitate device clinic efficiency and optimize patient care.

    Abstract Background: Remote monitoring (RM) can facilitate early detection of subclinical and symptomatic atrial fibrillation (AF), providing an opportunity to evaluate the need for stroke prevention therapies. We aimed to characterize the burden of RM AF alerts and its impact on anticoagulation of patients with device-detected AF.
    Methods: Consecutive patients with a cardiac implantable electronic device, at least one AF episode, undergoing RM were included and assigned an estimated minimum CHA
    Results: From 7651 individual, 389,188 AF episodes were identified, 3120 (40.8%) permanent pacemakers, 2260 (29.5%) implantable loop recorders (ILRs), 987 (12.9%) implantable cardioverter defibrillators, 968 (12.7%) cardiac resynchronization therapy (CRT) defibrillators, and 316 (4.1%) CRT pacemakers. ILRs transmitted 48.8% of all AF episodes. At twelve-months, 3404 (44.5%) AF < 6 min, 1367 (17.9%) 6 min-6 h, 1206 (15.8%) 6-24 h, and 1674 (21.9%) ≥ 24 h. A minimum CHA
    Conclusions: Despite being intensively managed via RM software system incorporating cues for anticoagulation, a substantial proportion of patients with increased stroke risk remained unanticoagulated after a device-detected AF episode of significant duration. These data highlight the need for improved clinical response pathways and an integrated care approach to RM.
