Heat stress can increase disease risk in fishes by reducing immune function. Interactions between redband trout (Oncorhynchus mykiss gairdneri) and Flavobacterium columnare, a causative agent of columnaris disease, provide an opportunity to investigate the effects of temperature on immune function and disease resistance during periods of thermal stress. We conducted three trials to characterise differences in immune function and mortality between redband trout held at 18°C and 21°C following challenge with F.

Study Design: We performed a retrospective study from electronic health records of children (≤21 years at death) who died with advanced heart disease at a single institution between 2012 and 2019 (n = 128). The main outcome was SPPC consult; we assessed clinical and sociodemographic factors associated with SPPC.
Purpose: Unlike most childhood cancers, therapy for ALL includes a prolonged maintenance phase during which children typically resume regular activities. Physicians need data regarding the persistent impact of COVID-19 in this population to help guide families after the pandemic.
Methods: The Pediatric Oncology COVID-19 Case Report (POCC) collects deidentified data (sociodemographics, clinical data [cancer, COVID-19 course]) on children, adolescents, and young adults with cancer and COVID-19 from 104 US pediatric oncology institutions.
Objective: Interdisciplinary care and pediatric to adult transitional programs have consistently shown medical and social value for individuals with complex medical conditions such as spina bifida (SB). Such interdisciplinary clinics are common in pediatrics but are rarely offered for adults. This survey-based study reports information related to transition, daily pain burden, and satisfaction with care delivery in an adult SB clinic.

Introduction: A subset of children with Chiari 1 malformation (CM-1) have a 4th ventricle arachnoid veil-a thin membrane covering the outlet of the 4th ventricle. Studies suggest that failure to disrupt this veil during posterior fossa decompression can reduce the likelihood of syringomyelia resolution. However, there is no reliable method for predicting the presence of the veil without direct surgical exploration.

We hypothesized that in situ analysis of the VOGM lesion using endoluminal tissue sampling (ETS) is feasible and may advance our understanding of VOGM genetics, pathogenesis, and maintenance.
Methods: We collected germline DNA (cheek swab) from patients and their families for genetic analysis.
Introduction: A cross-sectional study retrospectively evaluating the perceived usefulness of attending a multi-disciplinary, roundtable, educational prenatal clinic for mothers expecting children with myelomeningocele is presented.
Methods: Mothers who currently have children with SB completed a survey which evaluated their overall preparedness, spina bifida education, delivery plans, surgical expectations, and expectations in terms of quality of life and development. Open comments were also collected.
It has been suggested that follow-up visits for pediatric patients after full-mouth dental rehabilitation (FMDR) under general anesthesia (GA) are important to evaluate healing and restorative treatment, review oral hygiene instruction, provide nutritional counseling and address guardians' concerns. The purpose of this study was to evaluate pediatric dentists' current utilization of follow-up visits after GA and to evaluate pediatric dentists' and guardians' perceptions of their purpose and value. Three separate surveys were administered: (1) pediatric dentist survey, (2) guardian pre-appointment survey and (3) guardian post-appointment survey.

Spatially explicit, individual-based models provide an outlet for simulating these complex interacting eco-evolutionary processes. We expanded the existing Cost-Distance Meta-POPulation (CDMetaPOP) framework with inducible plasticity modelled as a habitat selection behaviour, using temperature or habitat quality variables, with a genetically based selection threshold conditioned on past individual experience.

We investigated local adaptation in redband trout (Oncorhynchus mykiss gairdneri) using genome scans for 547 samples from 11 populations across a wide range of habitats and thermal gradients in the interior Columbia River. We estimated allele frequencies for millions of single nucleotide polymorphism loci (SNPs) across populations using low-coverage whole genome resequencing, and used population structure outlier analyses to identify genomic regions under divergent selection between populations.

Methods: This observational study captured clinical and sociodemographic characteristics for children (≤ 21 years) receiving cancer therapy and infected with SARS-CoV-2 from the pandemic onset through February 19, 2021. The demographic and clinical characteristics of the cohort were compared with population-level pediatric oncology data (SEER).

Vaccination is an essential public health measure for infectious disease prevention. The exposure of the immune system to vaccine formulations with the appropriate kinetics is critical for inducing protective immunity. In this work, faceted microneedle arrays were designed and fabricated utilizing a three-dimensional (3D)-printing technique called continuous liquid interface production (CLIP).

Evaluation of fishway success has typically been conducted at local scales using metrics such as fish passage efficiency and passage time, but evaluations are increasingly used in broader assessments of whether passage facilities meet population-specific conservation and management objectives. Over 15 years, we monitored passage effectiveness at eight dams on the Columbia and Snake rivers for 26,886 radio-tagged spring-summer and fall Chinook Salmon O.

It is closely related to the evolutionary biology concept of adaptive potential. In this systematic literature review, we: (1) summarize the history of these topics and related fields; (2) assess relationship(s) between the concepts among disciplines and the use of the terms in climate change research, and evaluate methodologies, metrics, taxa biases, and the geographic scale of studies; and (3) provide a synthetic conceptual framework to clarify concepts.

Methods: A 13-question survey containing multiple-choice, Likert-type, and free-text questions on experiences, behaviors, and attitudes during the COVID-19 outbreak was sent to childhood cancer caregivers and completed between April 13 and May 17, 2020. Ordered logistic regression was used to investigate relationships between demographics, COVID-related experiences, and caregiver well-being.

Ubiquitous advertising of unhealthy foods, weight-loss products that are not evidence-based, and myths regarding weight loss could be particularly sabotaging in individuals with high levels of suggestibility, with or at risk of developing obesity. This study explored relationships between suggestibility, body mass index (BMI), and self-reported eating-related behaviors that vary among those with obesity.

Movement sensing technologies can monitor behaviors that are otherwise difficult to observe under field conditions and may enhance the ability to quantify behaviors at the population scale. We monitored steelhead trout () spawning behaviors in a seminatural enclosure using accelerometer telemetry tags while simultaneously observing behaviors with underwater cameras.

Predicting and managing risks for these populations requires data on acute and cumulative thermal exposure, the spatio-temporal distribution of adverse conditions, and the potentially mitigating effects of cool-water refuges.

However, current microneedle fabrication techniques are limited in their ability to fabricate microneedles rapidly and with a high degree of control over microneedle design parameters. We have previously demonstrated the ability to fabricate microneedle patches with a range of compositions and geometries using the novel additive manufacturing technique Continuous Liquid Interface Production (CLIP).
