Objectives We investigated machinelearningbased identification of presymptomatic COVID-19 and detection infection-related changes in physiology using a wearable device. Design Interim analysis prospective cohort study. Setting, participants interventions Participants from national study Liechtenstein were included. Nightly they wore the Ava-bracelet that measured respiratory rate (RR), heart (HR), HR variability (HRV), wrist-skin temperature (WST) skin perfusion. SARS-CoV-2 infection was...
Elasmobranch fishes (i.e., sharks, skates, and rays) exhibit remarkable wound-healing capabilities consistently maintain a high capacity for tissue regeneration throughout their lives. This wound healing may be particularly important neonatal elasmobranchs that are still developing immune system. However, little is known about the costs associated with potential influence of environmental variables or life history. In this study, we explore (1) impact minor, external injuries on growth body...
Marine protected areas (MPAs) can protect shark populations from targeted fisheries, but resident may remain exposed to stressors like capture as bycatch and environmental change. Populations of young sharks that rely on shallow coastal habitats, e.g. nursery areas, be at risk experiencing these stressors. The purpose this study was characterize various components the physiological stress response neonatal reef following exposure an exhaustive challenge under relevant conditions. To...
ABSTRACT Thermal dependence of growth and metabolism can influence thermal preference tolerance in marine ectotherms, including threatened data-deficient species. Here, we quantified the physiological performance neonates a tropical shark species (blacktip reef shark, Carcharhinus melanopterus) from shallow, nearshore habitats. We measured minimum maximum oxygen uptake rates (ṀO2), calculated aerobic scope, excess post-exercise consumption recovery exercise, critical maxima (CTmax), safety...
Mechanisms driving selection of body size and growth rate in wild marine vertebrates are poorly understood, thus limiting knowledge their fitness costs at ecological, physiological genetic scales. Here, we indirectly tested whether for size-related traits juvenile sharks that inhabit a nursery hosting two dichotomous habitats, protected mangroves (low predation risk) exposed seagrass beds (high risk), is influenced by foraging behaviour. Juvenile displayed continuum strategies between...
Sharks can incur a range of external injuries throughout their lives that originate from various sources, but some the most notable wounds in viviparous shark neonates are at umbilicus. Umbilical typically heal within 1 to 2 months post-parturition, depending on species, and therefore often used as an indicator neonatal life stage or relative measure age [e.g. grouping by umbilical wound classes (UWCs), according size umbilicus]. To improve comparisons early-life characteristics between...
Coastal sharks can use shallow, nearshore habitats as nursery areas, which is a behaviour that may increase fitness. The ecological benefits of shark areas are well studied; yet the physiological mechanisms enable to exploit coastal habitats, especially those experience extreme and dynamic temperatures, remain understudied. We hypothesised neonatal able thermally because temperature does not strongly affect their physiology. To test this hypothesis, we defined patterns area...
Abstract Acquiring and storing energy is vital to sharks of all age-classes. Viviparous shark embryos receive endogenous maternal reserves sustain the first weeks after birth. Then, in order maintain body condition, must start foraging. Our goal was understand whether investments vary between blacktip reef ( Carcharhinus melanopterus ) from two populations what extent condition initiation foraging might be affected by presumably variable investments. A total 546 young were captured at St....
It is unknown whether neurological symptoms are associated with brain injury after SARS-CoV-2 infections and related also emerge in Long-COVID patients. Biomarkers such as serum neurofilament light chain (sNfL) glial fibrillary acidic protein (sGFAP) can be used to elucidate neuro-axonal astroglial injuries. We investigated these biomarkers COVID-19 infection status, Long-COVID. From 146 individuals of the general population a post-acute, mild-to-moderate infection, sNfL sGFAP were measured...
The soluble urokinase plasminogen activator receptor (suPAR), as a correlate of chronic low-grade inflammation, may be used to predict individual cardiovascular risk. Since inflammation is thought associated with the development disease, this study aimed evaluate if suPAR plasma levels are correlated risk factors in young and healthy adults (aged 25–41 years). Consequently, data from GAPP (genetic phenotypic determinants blood pressure other factors) were investigate relation following...
During a mark–recapture survey from November 2014 until April 2017, 333 neonatal and juvenile blacktip reef sharks Carcharhinus melanopterus 302 sicklefin lemon Negaprion acutidens were tagged measured at the uninhabited isolated St. Joseph Atoll (Republic of Seychelles). Both species demonstrated seasonal reproductive synchronicity relatively large sizes birth. Despite extended times liberty > 2.5 years, majority recaptures found in close proximity to initial tagging location (< 500...
Abstract As environmental change persists, understanding resource use patterns is of value to predict the consequences shifting trophic structures. While many sharks are opportunistic predators, some exhibit prey selectivity, putting them at higher risk compared species with greater plasticity. In Gulf Mexico (GOM), Clupeids and Sciaenids comprise 69% blacktip shark ( Carcharhinus limbatus ) diets, which consequential considering potential responses these groups disturbance over harvesting....
The effects of anticoagulant EDTA and sodium heparin (SH) on stable carbon δ13 C nitrogen δ15 N isotopic values red blood cells (RBC) plasma in juvenile blacktip reef sharks Carcharhinus melanopterus were analysed. Plasma preserved with anticoagulants was not isotopically distinct from stored no-additive control tubes but RBC exhibited small enrichments when SH. Results suggest SH are viable for analyses fractions further studies advised to validate results.
Considering sex as a biological variable in modern digital health solutions, we investigated sex-specific differences the trajectory of four physiological parameters across COVID-19 infection. A wearable medical device measured breathing rate, heart rate variability, and wrist skin temperature 1163 participants (mean age = 44.1 years, standard deviation [SD] 5.6; 667 [57%] females). Participants reported daily symptoms confounders complementary app. machine learning algorithm retrospectively...
Abstract Background During and after mild (no hospitalization) or moderate (hospitalization without ICU) SARS-CoV-2 infections, a wide range of symptoms, including neurological disorders have been reported. It is, however, unknown if these symptoms are associated with brain injury whether related also emerge in patients suffering from Long-COVID. Neuronal biomarkers such as serum neurofilament light chain glial fibrillary acidic protein can be used to elucidate neuro-axonal astroglial...
Lower troponin concentrations measured in smokers a healthy population raise the question of whether lower threshold should be considered for tobacco users. We aim to evaluate differences levels according smoking status young adults. Participants aged 25–41 years were enrolled population-based observational study. The was self-assessed, and participants classified as never-, past-, current smokers. Pack-years calculated. High-sensitivity cardiac I (hs-cTnI) from thawed blood samples,...
