Background: The impact of biofeedback-based virtual reality (VR-BF) on pain and anxiety in pediatric surgical patients remains unexplored. Objective: The objective of this study was to evaluate the feasibility and acceptability of perioperative VR-BF use in children and adolescents. Methods: We performed a single-blind, 2-arm, randomized pilot trial. Children aged 12 to 18 years undergoing surgery with expected moderate-to-severe postoperative pain and more than 1 overnight admission were randomized (1:1) to the intervention or control group. Participants in the intervention group received VR-BF using ForeVR (functional outcome response to engaging virtual reality [VR]), a novel, gamified digital intervention that integrates respiratory biofeedback into an immersive VR environment to train children in vagal tone modulation, and the control group used Manage My Pain , an app designed to assist patients with recognizing and reflecting on their pain. Participants and caregivers were unblinded to their assigned intervention but blinded to the other arm’s technology; data analysts were masked to treatment allocation. The primary outcome was feasibility, assessed through recruitment, enrollment and randomization, retention, adherence, and outcome data collection. Secondary outcomes evaluated acceptability, including satisfaction and tolerability. Exploratory outcomes, including pain intensity, pain unpleasantness, and anxiety, were assessed in the VR-BF group. This trial was registered at ClinicalTrials.gov (NCT04943874) and is complete. Results: Of the 202 patients who were eligible for study participation, 70 were enrolled, and 65 (92.9%) patients completed the study (VR-BF, n=30; control, n=35). Female participants accounted for 41 (58.6%) of the participants, and the median age of participants was 16.2 (IQR 14.1-17.5) years. VR-BF participants completed a median of 4 (IQR 3-5) preoperative training sessions and 7 (IQR 2-9) postoperative sessions. Acceptability was high; only 2 (6.7%) would not use VR-BF again. Six VR-BF patients reported mild, transient adverse events (AEs), none of which were serious. VR-BF patients with baseline pain and anxiety scores ≥ 2 reported a median 1-point (IQR 0-2) reduction in pain intensity, unpleasantness, and anxiety immediately and up to 30 minutes postsession. Conclusions: Perioperative use of VR-BF is feasible and acceptable in pediatric surgical patients, with high recruitment, retention, and satisfaction and no serious AEs. These findings support a subsequent trial to assess the efficacy and long-term impact of this novel technology.

Background: Virtual reality (VR) is a novel technology with implications for pain and sensory processing. VR may serve as a novel, scalable method to deliver clinically validated therapy for pain management as an alternative or adjunct to opioids for acute pain. Given that psychological factors and pain perception are both components of postoperative pain, it may also be beneficial to incorporate modalities that decrease anxiety, such as active relaxation and guided meditation with VR. Unfortunately, these therapies are not widely available due to multiple barriers. VR has the potential to deliver pain-reducing, psychologically based therapy to children, thereby enhancing multimodal analgesia and potentially decreasing opioid use. This study investigates the role of VR in reducing pain and anxiety after surgery. Given the substantial risks associated with opioid use, particularly in younger populations, alternative pain management strategies are crucial. Objective: The primary aim of this study was to evaluate the efficacy of VR as a nonpharmacological intervention for managing postoperative pain intensity, pain unpleasantness, anxiety, and opioid use in children and adolescents undergoing Nuss repair of pectus excavatum. Methods: A single-center, prospective, randomized, controlled trial was conducted at a tertiary care children’s hospital and research center. Ninety children and adolescents (8-18 y) undergoing the Nuss procedure were randomized to guided relaxation or mindfulness VR (n=30) and distraction-based gaming VR (n=30), combined to form the VR group (n=60), and a control group using a passive 360° video (n=30). Patients received a 10-minute session on postoperative days 1 and 2. Pain intensity, pain unpleasantness, and anxiety were evaluated before and 0-, 15-, and 30-minute post-session. In-hospital pain scores, anxiety scores, and opioid use were collected. Results: Children and adolescents who participated in VR reported a significantly greater decrease in pain intensity from baseline (0.41, SE 0.23) compared with those in the 360° video group at 30 minutes ( P =.04) before multiplicity adjustment but not after multiplicity adjustment. There were no significant differences in pain scores or opioid use between the VR and control groups on postoperative day 1 or 2, nor were there changes in pain unpleasantness or anxiety at any time after the intervention. Conclusions: Daily, 10-minute VR sessions provided some trends toward transient analgesic and anxiolytic effects, albeit none that were statistically significant. VR did not significantly decrease overall pain scores or opioid usage, possibly due to the limited intervention duration and high standardized opioid use. Future studies should investigate extended and more frequent VR sessions and the integration of VR with other therapeutic modalities.

Background: Biofeedback-based virtual reality (VR-BF) is a novel, nonpharmacologic method for teaching patients how to control their breathing, which in turn increases heart rate variability (HRV) and may reduce pain. Unlike traditional forms of biofeedback, VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of biofeedback. This is the first study to systematically integrate VR-BF use in the pediatric perioperative setting, with the ultimate goal of evaluating the efficacy of VR-BF to reduce pain, anxiety, and opioid consumption once feasibility and acceptability have been established. Objectives: The primary objective was to develop a clinical trial protocol for VR-BF use in the pediatric perioperative setting, including preoperative education and training, and postoperative application of VR-BF in children undergoing surgery. A secondary objective was to evaluate the patient and parent experience with VR-BF. Methods: A total of 23 patients (12-18 years of age) scheduled for surgery at Nationwide Children’s Hospital were recruited using purposive sampling. Following training, participants independently completed a daily, 10-minute VR-BF session for 7 days before surgery and during their inpatient stay. Participants could use VR-BF up to 2 weeks after hospital discharge. Patient- and session-level data of VR-BF usage and achievement of target HRV parameters were measured to identify the optimal frequency and duration of sessions before and after surgery for this population. Standardized questionnaires and semistructured interviews were conducted to obtain qualitative information about patients’ experiences with VR-BF. Results: Patient-level data indicated that the highest odds of achieving 1 session under target HRV parameters was after 4 sessions (odds ratio [OR] 5.1 for 4 vs 3 sessions, 95% CI 1.3-20.6; OR 16.6 for 3 vs 2 sessions, 95% CI 1.2-217.0). Session-level data showed that a session duration of 9 to 10 minutes provided the greatest odds of achieving 1 session under target HRV parameters (OR 1.3 for 9 vs 8 min, 95% CI 1.1-1.7; OR 1.4 for 8 vs 7 min, 95% CI 1.1-1.8; OR 1 for 10 vs 9 min, 95% CI 0.9-1.2). Qualitative data revealed patient satisfaction with the VR-BF technology, particularly in managing perioperative stress (17/20, 85%). Few patients reported VR-BF as beneficial for pain (8/20, 40%). Conclusions: Children and adolescents undergoing surgery successfully learned behavioral strategies with VR-BF with 10-minute sessions once daily for 5 days. To integrate VR-BF as a therapeutic intervention in a subsequent clinical trial, patients will be instructed to complete three 10-minute sessions a day for 7 days after surgery.

Objective: Cognitive Behavioral Therapy (CBT) for youth with Disorders of Gut‐Brain Interaction (DGBIs) is effective; however, there are calls in the field to strengthen the evidence base and identify specific mechanisms of treatment that yield the most benefit for this patient population. A unique, systematic treatment approach of CBT with initial evidence for success for pediatric patients with DGBIs was evaluated to further demonstrate its clinical utility in this population.Methods: This was a retrospective study of 42 pediatric patients aged 11–17 years with DGBIs, who were diagnosed and referred for CBT by pediatric gastroenterology providers. Providers also completed a survey rating acceptability and effectiveness of CBT. The systematic CBT approach included 10 sessions delivered by a psychologist at an integrated Pediatric GI Clinic.Results: Review of 42 pediatric charts showed significant decreases in self‐reported functional disability, abdominal pain, as well as depression and anxiety symptoms pre‐ to post‐CBT completion. A moderation effect was observed where patients reporting higher levels of depressive symptoms and primary symptom of abdominal pain reported smaller reductions in functional impairment compared to those with lower levels of depression and primary symptom of nausea or vomiting. Pediatric Gastroenterology providers were satisfied with this psychological treatment approach.Conclusions: This study provides evidence for acceptability and effectiveness of implementation of a systematic CBT approach for pediatric DGBIs in an integrated GI clinic, as well as areas worthy of future research, including identifying the most important mechanisms of treatment and factors that influence treatment response.

The mink (Neogale sp.) has been important species in North American ecosystems and communities for millennia; before European colonization, Indigenous families hunted and trapped mink for their pelts. As part of the euro-colonial fur trade (~1600-1900), wide-spread and intense harvest of mink and other furbearers transformed ecosystems, including the likely extinction of the sea mink (Neogale macrodon) in the Gulf of Maine. The American mink (Neogale vison) has slowly moved into areas that were previously inhabited by the sea mink in coastal and island Maine. The expansion of American mink has been implicated as a potential cause for the declining seabird populations on Maine islands. Here, we use metabarcoding of American mink scat collected in the USFWS Maine Coastal Islands National Wildlife Refuge to evaluate if American mink are predating upon seabirds. Preliminary analysis of mink scat from Petit Manan Island has not implicated mink in bird predation but we did recover host DNA and dietary components including lobster and fish (Cunner). Currently, managers remove American mink from the Refuge islands to protect nesting seabirds but perhaps the seabird populations are returning to population sizes of when sea mink was present in the area. Harvest of furbearers as part of the euro-colonial fur trade may still have implications for ecosystem form and function today.

Ehlers-Danlos syndrome (EDS) is a heterogeneous group of inherited disorders of connective tissue. EDS hypermobility type (EDS-HT), characterized by joint hypermobility, is most common and increasingly recognized in pediatrics. Treatment involves protecting joints, preventing injuries, and managing symptoms/comorbidities. Pediatric EDS-HT patients often see multiple medical providers; however, data on healthcare utilization (HCU) in this population are lacking. This retrospective, electronic chart review examines HCU data 1 year prior and subsequent to a new diagnosis of EDS-HT using Villefranche criteria. Demographics, diagnoses, and HCU (office visits, therapies, hospital encounters/procedures, and tests) were obtained for N = 102 youth attending a Connective Tissue Disorder Clinic over a 21-month timeframe. After EDS-HT diagnosis, HCU patterns shifted to reflect greater involvement of therapy (physical, psychological, and occupational) and symptom management. More genetics, rheumatology, and orthopedics visits occurred prediagnosis, and more physical therapy, pain management, cardiology, and neurology visits occurred postdiagnosis. Testing and hospital encounter/procedure frequencies did not change. Overall, the pattern of HCU changed from diagnostic to treatment, in accordance with evidence-based EDS-HT care. Understanding HCU patterns of pediatric patients with EDS-HT can elucidate patient interaction with the health care system, with the potential to inform and improve the standard of care.
