Supplemental Materials Eikelboom et al. Neuropsychiatric and cognitive symptoms across the Alzheimer's disease clinical spectrum
<p>The objective of this study was to investigate the prevalence and trajectories of neuropsychiatric symptoms (NPS) in relation to cognitive functioning in a cohort of amyloid-<em>β</em> positive individuals across the Alzheimer's disease (AD) clinical spectrum. In this single-center observational study, we included all individuals who visited the Alzheimer Center Amsterdam and had 1) a clinical diagnosis of subjective cognitive decline (SCD), mild cognitive impairment (MCI), or probable AD dementia, and 2) were amyloid-<em>β</em> positive (A+). We measured NPS with the Neuropsychiatric Inventory (NPI), examining total scores and the presence of specific NPI domains. Cognition was assessed across five cognitive domains and with the MMSE. We examined trajectories including model based trends for NPS and cognitive functioning over time. We used linear mixed models to relate baseline NPI scores to cognitive functioning at baseline (whole-sample) and longitudinal time-points (subsample n=520, Mean=1.8 [SD=0.7] years follow-up). We included 1,524 amyloid-β positive individuals from the Amsterdam Dementia Cohort with A+ SCD (n=113), A+ MCI (n=321), or A+ AD dementia (n=1,090). NPS were prevalent across all clinical AD stages (≥1 NPS 81.4% in SCD, 81.2% in MCI, 88.7% in dementia; ≥1 clinically relevant NPS 54.0% in SCD, 50.5% in MCI, 66.0% in dementia). Cognitive functioning showed an uniform gradual decline; while in contrast, large intra-individual heterogeneity of NPS was observed over time across all AD groups. At baseline, we found associations between NPS and cognition in dementia that were most pronounced for NPI total scores and MMSE (range <em>β</em>=0.18 to 0.11, FDR-adjusted <em>p</em><0.05), while there were no cross-sectional relationships in SCD and MCI (range <em>β</em>=-0.32 to 0.36, all FDR-adjusted <em>p</em>>0.05). There were no associations between baseline NPS and cognitive functioning over time in any clinical stage (range <em>β</em>=-0.13 to 0.44, all FDR-adjusted <em>p</em>>0.05). NPS and cognitive symptoms are both prevalent across the AD continuum, but show a different evolution during the course of the disease.</p>

Drivers of change and stability in the gut microbiota of an omnivorous avian migrant exposed to artificial food supplementation
<p>Human activities shape resources available to wild animals, impacting diet and likely altering their microbiota and overall health. We examined drivers shaping microbiota profiles of common cranes (Grus grus) in agricultural habitats by comparing gut microbiota and crane movement patterns (GPS-tracking) over three periods of their migratory cycle, and by analyzing the effect of artificially-supplemented food provided as part of a crane-agriculture management program. We sampled fecal droppings in Russia (non-supplemented, pre-migration) and in Israel in late fall (non-supplemented, post-migration) and winter (supplemented and non-supplemented, wintering). As supplemented food is typically homogenous, we predicted lower microbiota diversity and different composition in birds relying on supplementary feeding. We did not observe changes in microbial diversity with food supplementation, as diversity differed only in samples from non-supplemented wintering sites. However, both food supplementation and season affected bacterial community composition and led to increased abundance of specific genera (mostly Firmicutes). Cranes from the non-supplemented groups spent most of their time in agricultural fields, likely feeding on residual grain when available, while food-supplemented cranes spent most of their time at the feeding station. Thus, non-supplemented and food-supplemented diets likely diverge only in winter, when crop rotation and depletion of anthropogenic resources may lead to a more variable diet in non-supplemented sites. Our results support the role of diet in structuring bacterial communities and show that they undergo both seasonal and human-induced shifts. Movement analyses provide important clues regarding host diet and behavior towards understanding how human-induced changes shape the gut microbiota in wild animals.</p>

Data supplement for: Disrupting cortico-cerebellar communication impairs dexterity
<p>This dataset, along with the corresponding code, is a supplement to "Disrupting cortico-cerebellar communication impairs dexterity" (Guo*, Sauerbrei* et al., eLife 2021). It consists of single-unit electrophysiology data from the pontine nuclei, Purkinje cells, cerebellar nuclei, and motor cortex of awake mice, along with measurements of the hand position of mice performing reaching movements.</p> <p>These data address the question of how the dynamics of motor cortex and cerebellum interact to control skilled reaching. First, we recorded from neurons in the pontine nuclei (PN), the bridge between cerebral cortex and the cerebellum, as mice reached to and grasped food pellets. Most PN neurons were strongly modulated by an acoustic go cue, by movement onset, or by both. Optogenetic stimulation of the PN strongly entrained spiking in Purkinje cells and the cerebellar nuclei, and induced transients in some motor cortical neurons. PN stimulation during a reach-to-grasp task induced a range of deficits, including decreases in success rate, increases in the standard deviation of hand position, increases in movement duration, and overreaching of the target. During movement, PN stimulation altered neural activity in the cerebellar nuclei and motor cortex, and a velocity decoding analysis revealed that these shifts in activity were consistent with the kinematic effects of stimulation. Our findings suggest that interaction between motor cortex and the cerebellum is essential for fine-tuning movements to enable accurate and precise behavior.</p> <p>Code required to generate the figures is available in the companion repository on Zenodo, and a list of which scripts generate which figure panels is contained in /docs/README.</p>

<p>The supplemental files in this deposition contribute additional information useful for understanding the analyses in the associated manuscript. Two files contain the annual (CARBONO Project measurement-year) data for productivity and for environmental conditions that were analyzed in the paper. The annual productivity metrics were derived from the CARBONO Project litterfall and tree-growth data that were provided and documented in prior Dryad data depositions. A third file in this deposition provides the daily data underlying the analyzed meteorological factors. The fourth file lists the standardized set of 66 test models that were used to test each of the five productivity metrics for environmental responses. The fifth file is an auxiliary table documenting tree mortality by year. The included README file documents the information in these files.</p>
Data supplement for: Agreement of analytical and simulation-based estimates of the required land depth in climate models
<p>Many current-generation climate models have land components that are too shallow. Under climate change conditions, the long-term warming trend at the surface propagates deeper into the ground than the commonly used 3-10m. Shallow models alter the terrestrial heat storage and distribution of temperatures in the subsurface, influencing the simulated land-atmosphere interactions. Previous studies focusing on annual timescales suggest that deeper models are required to match subsurface-temperature observations and the classic analytical heat conduction solution. However, for a systematic investigation of land-model deepening in the frame of anthropogenic climate change, the classic analytical solution is inaccurate because it does not mimic the timescale and amplitude of the simulated warming trend. This study intends to bridge the gap between analytical and simulation-based estimates of the subsurface thermodynamic state by adapting the classic analytical framework to mimic long-term anthropogenic warming. The analysis shows that a land-model depth of at least 170m is recommended for a proper simulation of the post-1850 ground climate, which differs up to 30% from the estimate of the classic approach. Compared to previous studies, this provides an accurate estimate of the required land model depth for long-term climate-change simulations and indicates the relative bias in insufficiently deep land models.</p>

Raw data for the article: A Randomized Controlled Trial of Antithrombin Supplementation During Extracorporeal Membrane Oxygenation
<p><strong>Objectives: </strong>Supplementation of antithrombin might decrease the amount of heparin needed to achieve a given anticoagulation target during extracorporeal membrane oxygenation. However, exogenous antithrombin itself may increase the risk of bleeding. We conceived a study to evaluate the effect of antithrombin supplementation in adult patients requiring venovenous extracorporeal membrane oxygenation for respiratory failure on heparin dose, adequacy of anticoagulation, and safety.</p> <p><strong>Design: </strong>Prospective randomized controlled trial.</p> <p><strong>Setting: </strong>ICUs of two Italian referral extracorporeal membrane oxygenation centers.</p> <p><strong>Patients: </strong>Adult patients requiring venovenous extracorporeal membrane oxygenation for severe respiratory failure and unfractionated heparin for systemic anticoagulation.</p> <p><strong>Interventions: </strong>Before extracorporeal membrane oxygenation start, patients were randomized to either receive antithrombin concentrate to maintain a plasmatic level 80-120% (treatment) or not (control) during the extracorporeal membrane oxygenation course.</p> <p><strong>Measurements and main results: </strong>The primary outcome was the total amount of heparin required to maintain activated partial thromboplastin time ratio 1.5-2. Secondary outcomes were anti-factor Xa, the incidence of hemorrhagic and thrombotic events, and the amount of blood products transfused. Twenty-four patients in the treatment group and 24 in the control group were included in the intention-to-treat analysis. Antithrombin was 109.5% (93.0-123.0%) in the treatment group and 84.0% (68.5-98.0%) in the control group (p = 0.001). Supplementation of antithrombin did not decrease heparin dose (13.5 international units/kg/hr [9.6-17.9 international units/kg/hr] vs 15.1 international units/kg/hr [10.7-18.3 international units/kg/hr] in the treatment and control group, respectively; p = 0.33) and anti-Factor Xa levels (0.4 international units/mL [0.3-0.5 international units/mL] vs 0.3 international units/mL [0.2-0.5 international units/mL] in the treatment group and control group respectively; p = 0.65). Bleeding, blood product transfusions, and thrombosis were not different in the two groups.</p> <p><strong>Conclusions: </strong>Antithrombin supplementation may not decrease heparin requirement nor diminish the incidence of bleeding and/or thrombosis in adult patients on venovenous extracorporeal membrane oxygenation.</p>

Large-scale supplemental feeding alters lay date and nest survival in Eastern Bluebirds but not in two species of chickadees
<p>Wild bird feeding is a popular and growing activity, with approximately half of households participating in nations including the United States, Canada, the United Kingdom, New Zealand, and Australia. Supplemental feeding can increase survival and reproductive success of birds (which is often a goal of supplemental feeding efforts), but it raises concerns about phenological mismatch, reduced clutch size, or increased risk of nest predation. Our objectives were to test whether access to supplemental food during the breeding season was correlated with (1) advanced egg-laying phenology, (2) increased clutch size, or (3) improved nest survival of 3 cavity-nesting species (Carolina Chickadee, <i>Poecile carolinensis</i>; Black-capped Chickadee, <i>P. atricapillus</i>; and<i> </i>Eastern Bluebird, <i>Sialia</i> <i>sialis</i>) at a large spatial scale (United States and Canada; 22 degrees latitude difference and 55 degrees longitude difference). We examined data from 24,528 nest attempts submitted to NestWatch from 2014–2019. For Eastern Bluebirds, birds with access to supplemental insects initiated clutches 5.83 (± 0.89 SE) days earlier than birds without access to food subsidies, while predicted nest survival was 5% greater for birds with access to supplemental insects (probability of nest success = 0.79, 95% CI = 0.77–0.81) when compared to birds without (0.74, 95% CI = 0.72–0.75). Clutch size of Eastern Bluebirds did not differ between birds with and without access to supplemental insects. For chickadees, supplemental feeding (of seeds, suet, insects, or fruit) was not correlated with phenology, clutch size, or nest survival. <span>Our results suggest that supplemental feeding of insects can be an effective tool for increasing nest survival in Eastern Bluebirds and potentially other food-limited insectivores. However, the efficacy of supplemental feeding for improving reproductive success varies across <a>taxa</a></span><span>. </span>Our results can help elucidate how wild bird feeding contributes to global phenomena such as earlier nesting, nest survival, and population <a>change</a>.</p>
