    Abstract Collective motion of organisms is a widespread phenomenon exhibited by many species, most commonly associated with colonial birds and schools of fish. The benefits of schooling behavior vary from defense against predators, increased feeding efficiency, and improved endurance. Schooling motions can be energetically beneficial as schools allow for channeling and vortex-based interactions, creating a less demanding stroke rate to sustain high swimming velocities and increased movement efficiency. Biomimetics is a fast-growing field, and there have been several attempts to quantify the hydrodynamics behind group dynamics and the subsequent benefits of increased maneuverability, which can be applied to unmanned vehicles and devices traveling in a group or swarm-like scenarios. Earlier efforts to understand these phenomena have been composed of physical experimentation and numerical simulations. This literature review examines the existing studies performed to understand the hydrodynamics of group collective motion inspired by schooling habits. Both numerical simulation and physical experimentation are discussed, and the benefits and drawbacks of the two approaches are compared to help future researchers and engineers expand on these models and concepts. This paper also identifies some of the limitations associated with different approaches to studies on fish schooling and suggests potential directions for future work.

    Abstract Objective: Economic evaluations of treatments help to inform decisions on allocating health care resources. These evaluations involve comparing costs and effectiveness in terms of quality of life. To calculate quality-adjusted life years, generic health related quality of life is often used, but is criticized for not being sensitive to change in mental health populations. Another approach, using experienced well-being measured through capabilities with the ICECAP-A, has been proposed as an alternative. The aim of this study was to investigate whether changes in individuals with eating disorder (ED) symptoms can be better captured using health related quality of life (EQ-5D-5L) or well-being (ICECAP-A).
    Method: Measurements at two time points with an interval of 1 year were used from a sample of 233 participants with self-reported ED symptoms. An analysis of variance was used to test whether the EQ-5D-5L and ICECAP-A differed in sensitivity to change over time. In order to compare the two questionnaires in terms of clinically significant outcome, the reliable change index and clinical cut-off score were calculated.
    Results: The two questionnaires did not differ in sensitivity to change. More individuals had recovered but also more had deteriorated according to the EQ-5D-5L compared to the ICECAP.
    Discussion: The present study revealed no differences in sensitivity to change in health-related quality of life or well-being in individuals with ED symptoms in the context of mild clinical change. Results corroborated the pervasiveness of low quality of life in this population, even after alleviation of ED symptoms.
    Public significance statement: Measuring treatment benefits in terms of improvements in quality of life is an integral part of economic evaluations in health care. It was expected that these treatment benefits would be better captured as changes in well-being (measured with the ICECAP-A) than as changes in health-related quality of life (measured with the EQ-5D-5L) for individuals with ED symptoms. Based on the results of this study, no preference for one of the two approaches was found.

    Abstract Background: The objective was to determine the extent that eGFR formulas correspond to measured plasma iohexol clearance (iGFR) in children with normal or near normal kidney function, particularly how different eGFR formulas yield discordant results.
    Methods: iGFR from 2 (iGFR-2pt) and 4 (iGFR-4pt) time points along with creatinine and/or cystatin C-based eGFR were measured in children with mild CKD, stages 1-2. eGFR was calculated using 6 equations: 3 under 25 (U25) formulas from the Chronic Kidney Disease in Children (CKiD) study, the full age-combined cystatin C (cysC) and creatinine spectrum (FAS-combined), the European Kidney Function Consortium (EKFC-creatinine) equation, and the Chronic Kidney Disease Epidemiology Collaboration (CKD-epi) cysC-based equation.
    Results: Twenty-nine children were included, of which 22 had discordant creatinine vs. cystatin C-based eGFR by ≥ 15mL/min/1.73 m
    Conclusion: The formulas that most closely approximated the measured GFR varied depending on the pattern of discordant eGFR results. Based on the results, we recommend using the CKiD U25-combined formula to screen for children with a low GFR. Either the CKiD U25-combined or FAS-combined would be recommended for changes in eGFR longitudinally. However, because all formulas were discordant from the iGFR-4pt in over a third of participants, further refinement of pediatric eGFR formulas is needed at the normal/near-normal range. A higher resolution version of the Graphical abstract is available as Supplementary information.

    Abstract Objectives: To quantitatively measure liver biopsy adequacy requirements and the effect of a teaching intervention that uses a virtual biopsy platform.
    Methods: A library of virtual liver biopsies was created using digital whole-slide, trichrome-stained tissue sections from liver resection material and QuPath image analysis software. Blinded participants staged fibrosis on the virtual biopsies before and after a teaching intervention.
    Results: This platform both modeled adequacy requirements for cirrhosis diagnosis on biopsy material and measured the effect of a teaching intervention on participant performance. Using this platform, diagnostic accuracy for cirrhosis could be modeled according to the function y = λ(1 ‒ e‒x/γ). The platform demonstrated that the relationship between biopsy size and diagnostic accuracy was statistically significant and that biopsies smaller than 6 mm long and 0.8 mm wide were insufficient to diagnosis cirrhosis. The platform also measured improvement in fibrosis staging accuracy among participants following a teaching intervention.
    Conclusions: These results provide proof of concept for a virtual biopsy method by which outstanding questions in anatomic pathology can be addressed quantitatively using open source software. Future work is needed to validate these findings in clinical practice.

    Abstract Objective: Only half of the patients with eating disorders (EDs) fully recover. To increase these rates, knowledge about predictors is essential. Previous studies found that purging behaviors, BMI, ED duration, and depression, predicted symptomatic ED recovery. The current study investigated these four predictors for symptomatic improvement and the subjective experience of recovery.
    Method: Participants who completed the baseline and second wave of the Netherlands Eating disorder Registry (NER) (N = 374), were categorized into: (1) Subjective recovery; (2) Clinical improvement; (3) Symptomatic recovery. Using regression analyses, it was investigated if the four baseline factors predicted recovery at wave two. Effects were compared among a binge-purging and restricting group.
    Results: In total, 136 participants were subjectively recovered, 135 showed clinical improvement, and 70 were symptomatically recovered. Overlap occurred between definitions. Lower depression scores predicted subjective recovery (OR 0.77, p < .001) and clinical improvement (OR 0.80, p < .001), and shorter ED duration predicted all definitions (OR 0.99, p < .001; OR 0.99, p < .001; OR 0.99, p = .013). Similar effects were found in the binge-purging group.
    Discussion: Our study emphasized that the same predictors, like depression, apply to symptomatic improvement and the personal experience of recovery. Depression appears an important factor during ED treatment.
    Public significance: Recovery rates for EDs are low. To understand this, knowledge about predictors of ED recovery is essential. This study examined the effects of four established predictors across symptomatic improvement and subjective recovery (a more personal experience of recovery). Lower depression scores predicted both, indicating that depression appears important for multiple definitions of recovery and therefore warrants attention during ED treatment.

    Abstract Background: In children with chronic kidney disease (CKD), certain risk factors are associated with faster eGFR decline and earlier kidney failure. Whether these factors have lingering effects on post-transplant eGFR trajectory remains unclear. We characterized pre- and post-transplant eGFR trajectories in pediatric kidney transplant recipients by their pre-kidney replacement therapy (KRT) risk factors.
    Methods: We studied eGFR trajectories before KRT initiation and after transplantation among Chronic Kidney Disease in Children (CKiD) Study participants. We used mixed-effects models to compare pre-KRT versus post-transplant eGFR trajectories within individual participants by 7 pre-KRT risk factors: glomerular/non-glomerular etiology, race, preemptive transplant, proteinuria, albuminuria, and systolic/diastolic blood pressure (SBP/DBP).
    Results: We analyzed 1602 pre-KRT and 592 post-transplant eGFR measurements from 246 transplant recipients. Mean annual eGFR decline was decreased from 18.0% pre-KRT (95%CI, 16.1-19.8) to 5.0% post-transplant (95%CI, 3.3-6.7). All 7 pre-KRT risk factors showed strong associations with faster pre-KRT eGFR decline, but not with post-transplant eGFR decline; only albuminuria, high SBP, and high DBP reached statistical significance with notably attenuated associations. In our multivariable model of the pre-KRT risk factors, post-transplant eGFR decline was more rapid only when albuminuria and high SBP were both present.
    Conclusions: eGFR decline substantially slows down after transplant even among children with rapidly progressing forms of CKD. Nonetheless, those who had albuminuria and high SBP before KRT might continue to show faster eGFR decline after transplant, specifically when both risk factors were present. This subgroup might benefit from intensive pre-transplant management for at least one of the two risk factors. A higher resolution version of the Graphical abstract is available as Supplementary information.

    Abstract Objective: To optimize treatment recommendations for eating disorders, it is important to investigate whether some individuals may benefit more (or less) from certain treatments. The current study explored predictors and moderators of an automated online self-help intervention "Featback" and online support from a recovered expert patient.
    Methods: Data were used from a randomized controlled trial. For a period of 8 weeks, participants aged 16 or older with at least mild eating disorder symptoms were randomized to four conditions: (1) Featback, (2) chat or e-mail support from an expert patient, (3) Featback with expert-patient support, and (4) a waitlist. A mixed-effects partitioning method was used to see if age, educational level, BMI, motivation to change, treatment history, duration of eating disorder, number of binge eating episodes in the past month, eating disorder pathology, self-efficacy, anxiety and depression, social support, or self-esteem predicted or moderated intervention outcomes in terms of eating disorder symptoms (primary outcome), and symptoms of anxiety and depression (secondary outcome).
    Results: Higher baseline social support predicted less eating disorder symptoms 8 weeks later, regardless of condition. No variables emerged as moderator for eating disorder symptoms. Participants in the three active conditions who had not received previous eating disorder treatment, experienced larger reductions in anxiety and depression symptoms.
    Discussion: The investigated online low-threshold interventions were especially beneficial for treatment-naïve individuals, but only in terms of secondary outcomes, making them well-suited for early intervention. The study results also highlight the importance of a supportive environment for individuals with eating disorder symptoms.
    Public significance: To optimize treatment recommendations it is important to investigate what works for whom. For an internet-based intervention for eating disorders developed in the Netherlands, individuals who had never received eating disorder treatment seemed to benefit more from the intervention than those who had received eating disorder treatment, because they experienced larger reductions in symptoms of depression and anxiety. Stronger feelings of social support were related to less eating disorder symptoms in the future.

    Abstract High-throughput, spatially resolved gene expression techniques are poised to be transformative across biology by overcoming a central limitation in single-cell biology: the lack of information on relationships that organize the cells into the functional groupings characteristic of tissues in complex multicellular organisms. Spatial expression is particularly interesting in the mammalian brain, which has a highly defined structure, strong spatial constraint in its organization, and detailed multimodal phenotypes for cells and ensembles of cells that can be linked to mesoscale properties such as projection patterns, and from there, to circuits generating behavior. However, as with any type of expression data, cross-dataset benchmarking of spatial data is a crucial first step. Here, we assess the replicability, with reference to canonical brain subdivisions, between the Allen Institute's in situ hybridization data from the adult mouse brain (Allen Brain Atlas (ABA)) and a similar dataset collected using spatial transcriptomics (ST). With the advent of tractable spatial techniques, for the first time, we are able to benchmark the Allen Institute's whole-brain, whole-transcriptome spatial expression dataset with a second independent dataset that similarly spans the whole brain and transcriptome. We use regularized linear regression (LASSO), linear regression, and correlation-based feature selection in a supervised learning framework to classify expression samples relative to their assayed location. We show that Allen Reference Atlas labels are classifiable using transcription in both data sets, but that performance is higher in the ABA than in ST. Furthermore, models trained in one dataset and tested in the opposite dataset do not reproduce classification performance bidirectionally. While an identifying expression profile can be found for a given brain area, it does not generalize to the opposite dataset. In general, we found that canonical brain area labels are classifiable in gene expression space within dataset and that our observed performance is not merely reflecting physical distance in the brain. However, we also show that cross-platform classification is not robust. Emerging spatial datasets from the mouse brain will allow further characterization of cross-dataset replicability ultimately providing a valuable reference set for understanding the cell biology of the brain.
