Much of biodiversity remains undiscovered, causing species and their functions to remain unrealized and potentially lost in ignorance. Here we use extensive species-level data in a time-to-event model framework to identify taxonomic and geographic discovery gaps in terrestrial vertebrates. Biological, environmental and sociological factors all affect discovery probability and together provide strong predictive ability for species discovery. Our model identifies distinct taxonomic and geographic unevenness in future discovery potential, with greatest opportunities for amphibians and reptiles, and for Neotropical and Indo-Malayan forests. Brazil, Indonesia, Madagascar and Colombia emerge as holding greatest discovery opportunities, with a quarter of potential discoveries estimated. These findings highlight the importance of international policy support for basic taxonomic research and the potential of quantitative models to aid species discovery.The hominin fossil record of Island Southeast Asia (ISEA) indicates that at least two endemic 'super-archaic' species-Homo luzonensis and H. floresiensis-were present around the time anatomically modern humans arrived in the region >50,000 years ago. Intriguingly, contemporary human populations across ISEA carry distinct genomic traces of ancient interbreeding events with Denisovans-a separate hominin lineage that currently lacks a fossil record in ISEA. To query this apparent disparity between fossil and genetic evidence, we performed a comprehensive search for super-archaic introgression in >400 modern human genomes, including >200 from ISEA. Our results corroborate widespread Denisovan ancestry in ISEA populations, but fail to detect any substantial super-archaic admixture signals compatible with the endemic fossil record of ISEA. We discuss the implications of our findings for the understanding of hominin history in ISEA, including future research directions that might help to unlock more details about the prehistory of the enigmatic Denisovans.

This research characterized mucociliary clearance (MCC) in young children with cystic fibrosis (CF).

Fourteen children (5-7 years old) with CF underwent two baseline MCC measurements (Visits 1 and 2); one MCC measurement approximately 1 year later (Visit 3); and measurements of lung clearance index (LCI), a measure of ventilation inhomogeneity.

Median (range) percent MCC through 60 min (MCC60) was similar on Visits 1 and 2 with 11.0 (0.9-33.7) and 12.8 (2.7-26.8), respectively (p = 0.95), and reproducible (Spearman Rho = 0.69; p = 0.007). Mucociliary clearance did not change significantly over 1 year with median percent MCC60 on Visit 3 [12.8 (3.7-17.6)] similar to Visit 2 (p = 0.58). Lower percent MCC60 on Visit 3 was significantly associated with higher LCI scores on Visit 3 (N = 14; Spearman Rho = -0.56; p = 0.04).

Tests of MCC were reproducible and reliable over a 2-week period and stable over a 1-year period in 5-7-year-old children with CF. Lower MCC values were associated with increased ventilasurements of mucociliary clearance were reproducible and reliable over a 2-week period and stable over a 1-year period. Variability in MCC between children was associated with differences in ventilation homogeneity, such that children with lower MCC values had increased ventilation inhomogeneity. CH5126766 These results suggest that measurements of MCC could be used in short-term clinical trials of interventions designed to modulate MCC and as a new, non-invasive test to evaluate early lung pathology in children with CF.

To characterize telemedicine use among pediatric subspecialties with respect to clinical uses of telemedicine, provider experience, and patient perceptions during the COVID-19 pandemic.

We performed a mixed-methods study of telemedicine visits across pediatric endocrinology, nephrology, orthopedic surgery, and rheumatology at a large children's hospital. We used deductive analysis to review observational data from 40 video visits. Providers and patients/caregivers were surveyed around areas of satisfaction and communication.

We found adaptations of telemedicine including shared-screen use and provider-guided parent procedures among others. All providers felt that it was safest for their patients to conduct visits by video, and 72.7% reported completing some component of a clinical exam. Patients rated the areas of being respected by the clinical staff/provider and showing care and concern highly, and the mean overall satisfaction was 86.7 ± 19.3%.

Telemedicine has been used to deliver care to pediatrimic from both a provider and patient perspective, in four different pediatric subspecialties. Prior to COVID-19, pediatric telehealth landscape analysis suggested that many pediatric specialty practices had pilot telehealth programs, but there are few published studies evaluating telemedicine performance through the simultaneous patient and provider experience as part of standard care. We describe novel uses and adaptations of telemedicine during a time of rapid deployment in pediatric specialty care.

Extremely low gestational age newborns (ELGANs) are at risk of neurodevelopmental impairments that may originate in early NICU care. We hypothesized that early oxygen saturations (SpO

), arterial pO

levels, and supplemental oxygen (FiO

) would associate with later neuroanatomic changes.

SpO

, arterial blood gases, and FiO

from 73 ELGANs (GA 26.4 ± 1.2; BW 867 ± 179 g) during the first 3 postnatal days were correlated with later white matter injury (WM, MRI, n = 69), secondary cortical somatosensory processing in magnetoencephalography (MEG-SII, n = 39), Hempel neurological examination (n = 66), and developmental quotients of Griffiths Mental Developmental Scales (GMDS, n = 58).

The ELGANs with later WM abnormalities exhibited lower SpO

and pO

levels, and higher FiO

need during the first 3 days than those with normal WM. They also had higher pCO

values. The infants with abnormal MEG-SII showed opposite findings, i.e., displayed higher SpO

and pO

levels and lower FiO

need, than those with better outcomes.
