Abstract	To control elevation underwater, aquatic vertebrates integrate multisensory information (e.g., vestibular, visual, proprioceptive) to guide posture and swim kinematics. Here we characterized how larval zebrafish changed posture and locomotive strategies after imposed instability (decreased buoyancy) in the presence and absence of visual cues. We discovered that larvae sank more after acute loss of lateral line (flow-sensing) hair cells. In response, larvae engaged different compensatory strategies, depending on whether they were in the light or dark. In the dark, larvae swam more frequently, engaging their trunk to steer their nose up and climb more effectively. However, in the light, larvae climbed more often, engaging both pectoral fins and trunk to elevate. We conclude that larvae sense instability and use vestibular and visual information as available to control posture and trajectory. Our work is a step towards understanding the multisensory neural computations responsible for control strategies that allow orientation and navigation in depth.

Article ; Online: Educational support needs of injured children and their families: A qualitative study.

Jones, Samantha / Tyson, Sarah / Davis, Naomi / Yorke, Janelle

Abstract	Objective: To explore the educational support needs of injured children and families. Patients: Thirteen injured children and/or their parents (n = 19) discharged from a major trauma centre within 12 months. Methods: Semi-structured interviews analysed with thematic analysis. Results: Theme 1: communication and information needs. Schools need help to understand the effects of children's injuries and the adjustments required for their return to school, such as how to involve chil-dren in the more active elements of the curriculum. Thus, effective communication between the injur-ed child, their family, health and education professionals and outside agencies is needed. A specialist key-worker could co-ordinate communication and school return. Theme 2: Educational support needs. Injured children experience changes to their appearance, new symptoms, and altered physical and cognitive abilities. Their absence from school often adversely affects their friendships. Consequently, injured children need continued access to education throughout recovery, support with learning, a flexible timetable, opportunities for social integration, involvement in all aspects of the curriculum, and environmen-tal adaptations to maintain their health and safety. Conclusion: Children with different types of injuries have similar needs for flexible learning and environmental accommodations. Social integration and participation in physical activity should be specific goals for school return.

Abstract	Background: Age and sex differences may exist in the frequency (incidence, prevalence) or symptoms of neuropathic pain (NP) and complex regional pain syndrome (CRPS) due to biopsychosocial factors (e.g., neurodevelopment, physiological and hormonal changes, psychosocial differences) that evolve through childhood and adolescence.2 Age and sex differences may have implications for evaluating screening and diagnostic tools and treatment interventions. Objective: To map the existing literature on pediatric NP and CRPS with respect to age and sex distributions, and age and sex differences in symptomology and frequency. Methods: A scoping literature review was conducted. Databases were searched from inception to January 2023. Data were collected on study design, setting, demographics, and age and sex differences in frequency and symptoms. Results: Eighty-seven studies were included. Distribution of participants with CRPS (n=37 studies) was predominantly early adolescence (10-14 years) and female sex, while NP (n=42 studies) was most commonly reported throughout adolescence (10-19 years) in both sexes. Forty-one studies examined age and sex differences in frequency; 6 studies reported higher frequency in adolescence. Very few studies (n=11) examined differences in symptomology. Discussion: Large epidemiological studies are required to further understand age and sex differences in frequency of pediatric NP and CRPS. Age and sex differences must be considered when evaluating screening and diagnostic tools and treatment interventions to ensure relevance and validity to both sexes and across ages. Validated tools will improve understanding of age- and sex-dependent differences in symptoms, pathophysiology, and psychosocial impact of pediatric NP and CRPS.

Article ; Online: Partial compensation to delayed auditory feedback: An analysis of syllable duration.

Abstract	Altered feedback perturbation studies have shown that speakers only partially compensate for shifts in vocal pitch, intensity, or spectral content. The partial compensation generally plateaus around 30%-40% of the non-shifted, baseline production and is proposed to reflect the integrated effect of altered (auditory) and non-altered (somatosensory) sensory feedback. The authors hypothesized that the same pattern should hold for changes in syllable duration with delayed auditory feedback. To test this, the authors calculated average syllable duration from 21 young adults who read a standard passage as auditory feedback was delayed by 0, 10, 50, 100, 200, 300, and 600 ms. Given the complex nature of speech errors elicited under delayed auditory feedback, the authors compared durational effects across two broad error categories: prolongations and repetitions. Average syllable duration increased non-linearly and reached a peak near 40% of baseline durations. Separated by error type, prolongations, and distortions made up 89% of perceived errors. Only 9% of perceived errors were identified as repetitions. Unlike prolongations, however, the duration of repeated tokens ranged from 74% to 110% of the target syllable and compensated fully for the delay. These results are consistent with the notion that increasing syllable duration compensates partially for delays in auditory feedback. The compensation pattern resembles that of responses to other forms of altered auditory feedback, which suggests that this may be a general attribute of low-level, sensorimotor compensation. The higher frequency of prolongation occurrences further suggests that these may be the primary means of compensation for delayed auditory feedback. Repetitions, on the other hand, likely reflect compensatory mechanisms of higher-level motor planning or sequencing processes.

Abstract	In this retrospective, exploratory study, intake and outcome data were compiled from 1,373 U.S. animal shelters for which such data were reported consistently across a five-year study period (2016-2020). Linear regression analysis was used to examine the five-year trends and the impacts of the first year of the COVID-19 pandemic (2020) on the overall trends in intake and outcomes in U.S. animal shelters. The results of the analysis reveal that total intake and euthanasia for both dogs and cats significantly decreased over the study period. The adoption, return-to-owner, return-to-field, and transfer (for cats) categories as a percentage of intake all showed significant increases. Live release rates as a function of total intakes and total outcomes for both dogs and cats showed significant increases over the study period. The findings from this study address a critical gap in the field by summarizing emerging trends at the national level in how cats and dogs are being served in U.S. animal shelters.

Abstract	Objective(s): To measure the success rate of primary medical therapy in managing retained products of conception (RPOC) in women with secondary postpartum haemorrhage (PPH) and to identify factors associated with need for surgical management. Study design: Postpartum patients presenting to a tertiary women's hospital Emergency Department between July 2020 and December 2022 with secondary PPH and evidence of RPOC on ultrasound were recruited. Clinical information relating to the presentation was collected prospectively. Antenatal and intrapartum data were collected from medical record and Birthing Outcome System database review. The primary outcome was the success of medical management for RPOC, defined by the implementation of medical or expectant management without subsequent need for surgical intervention. Results: Forty-one patients with RPOC underwent primary medical or expectant management. Twelve patients (29%) were managed successfully with medical management, while twenty-nine (71%) proceeded to surgical management. Medical management involved antibiotics (n = 37, 90%), prostaglandin E1 analogue (n = 14, 34%) and other uterotonics (n = 3, 7%). A greater endometrial thickness on ultrasound was significantly associated with a requirement for secondary surgical intervention (p < 0.05). There was an association approaching statistical significance between a higher sonographic volume of RPOC and the failure of medical management (p = 0.07). There was no statistically significant association between the mode of delivery or the number of days postpartum with the success of medical management. Conclusion(s): For patients presenting with secondary PPH and sonographic RPOC, over two thirds required surgical management. Increased endometrial thickness was associated with an increased requirement for surgical management.

Abstract	Background: Secondary postpartum haemorrhage (PPH) complicates ~1% of pregnancies and can cause serious maternal morbidity. However, evidence guiding optimal management is scarce and often based on case series and expert opinion. Aims: To measure the success of primary medical therapy in managing secondary PPH and to identify factors associated with need for surgical management. Materials and methods: Postpartum patients presenting to a tertiary women's hospital emergency department between July 2020 and October 2021 with secondary PPH were recruited. Data from the acute presentation were prospectively collected. Antenatal and intrapartum data were collected from medical record review. The primary outcome was the success of medical management for secondary PPH, defined by the implementation of medical or expectant measures without subsequent need for surgical intervention. Results: One-hundred and twenty patients underwent primary medical management for secondary PPH. Ninety-eight (82%) were managed successfully with medical management and 22 (18%) required surgery. Medical management involved misoprostol (n = 33; 27.5%), antibiotics (n = 108; 90%), and less commonly other uterotonics (n = 6; 5%). Factors associated with lower rates of successful medical management included: antecedent manual removal of placenta (MROP) (odds ratio (OR) 0.2, P = 0.047), primary PPH ≥500 mL (OR 0.39, P = 0.048) or ≥1 L (OR 0.24, P = 0.009), >200 mL blood loss at presentation (OR 0.17, P = 0.015), increasing time post-delivery (OR 0.84, P = 0.044), retained products of conception (RPOC) on ultrasound (OR 0.024, P = 0.001) and vaginal birth (OR 0.27, P = 0.027). Conclusion: Medical management was highly successful. Vaginal birth, MROP, primary PPH, RPOC on ultrasound and increasing time post-delivery were associated with increased need for surgical management.

Abstract	Objective: To explore the needs of children and their families after a child's traumatic injury. Design: Semi-structured qualitative interviews with purposeful sampling for different types of injuries and a theoretical thematic analysis. Participants: 32 participants; 13 children living at home after a traumatic injury, their parents/guardians (n=14) and five parents whose injured child did not participate. Setting: Two Children's Major Trauma Centres (hospitals) in England. Results: Interviews were conducted a median 8.5 months (IQR 9.3) postinjury. Injuries affected the limbs, head, chest, abdomen, spine or multiple body parts. Participants highlighted needs throughout their recovery (during and after the hospital stay). Education and training were needed to help children and families understand and manage the injury, and prepare for discharge. Information delivery needed to be timely, clear, consistent and complete, include the injured child, but take into account individuals' capacity to absorb detail. Similarly, throughout recovery, services needed to be timely and easily accessible, with flexible protocols and eligibility criteria to include injured children. Treatment (particularly therapy) needed to be structured, goal directed and of sufficient frequency to return injured children to their full function. A central point of contact is required after hospital discharge for advice, reassurance and to coordinate ongoing care. Positive partnerships with professionals helped injured children and their families maintain a sense of hope and participate in joint decision making about their care. Conclusion: Throughout the full trajectory of recovery injured children and their families need family centred, accessible, flexible, coordinated health services, with more effective harmonious, communication between professionals, the child and their family. There is a requirement for support from a single point of contact and a system that monitors the needs of the injured child and their family after hospital discharge.
