Association of Major Depressive Symptoms With Endorsement of COVID-19 Vaccine Misinformation Among US Adults.

Importance: Misinformation about COVID-19 vaccination may contribute substantially to vaccine hesitancy and resistance.

Objective: To determine if depressive symptoms are associated with greater likelihood of believing vaccine-related misinformation.

Design, Setting, And Participants: This survey study analyzed responses from 2 waves of a 50-state nonprobability internet survey conducted between May and July 2021, in which depressive symptoms were measured using the Patient Health Questionnaire 9-item (PHQ-9).

Cumulative effects of human footprint, natural features and predation risk best predict seasonal resource selection by white-tailed deer.

Land modified for human use alters matrix shape and composition and is a leading contributor to global biodiversity loss. It can also play a key role in facilitating range expansion and ecosystem invasion by anthrophilic species, as it can alter food abundance and distribution while also influencing predation risk; the relative roles of these processes are key to habitat selection theory. We researched these relative influences by examining human footprint, natural habitat, and predator occurrence on seasonal habitat selection by range-expanding boreal white-tailed deer (Odocoileus virginianus) in the oil sands of western Canada.

Association Between Social Media Use and Self-reported Symptoms of Depression in US Adults.

Importance: Some studies suggest that social media use is associated with risk for depression, particularly among children and young adults.

Objective: To characterize the association between self-reported use of individual social media platforms and worsening of depressive symptoms among adults.

Design, Setting, And Participants: This survey study included data from 13 waves of a nonprobability internet survey conducted approximately monthly between May 2020 and May 2021 among individuals aged 18 years and older in the US.

Persistence of symptoms up to 10 months following acute COVID-19 illness.

Importance: COVID-19 symptoms are increasingly recognized to persist among a subset of individual following acute infection, but features associated with this persistence are not well-understood.

Objective: We aimed to identify individual features that predicted persistence of symptoms over at least 2 months at the time of survey completion.Design: Non-probability internet survey.

Association of Acute Symptoms of COVID-19 and Symptoms of Depression in Adults.

This survey study investigates where acute coronavirus disease 2019 (COVID-19) is associated with the probability of subsequent depressive symptoms among US adults.

Environmental DNA from multiple pathogens is elevated near active Atlantic salmon farms.

The spread of infection from reservoir host populations is a key mechanism for disease emergence and extinction risk and is a management concern for salmon aquaculture and fisheries. Using a quantitative environmental DNA methodology, we assessed pathogen environmental DNA in relation to salmon farms in coastal British Columbia, Canada, by testing for 39 species of salmon pathogens (viral, bacterial, and eukaryotic) in 134 marine environmental samples at 58 salmon farm sites (both active and inactive) over 3 years. Environmental DNA from 22 pathogen species was detected 496 times and species varied in their occurrence among years and sites, likely reflecting variation in environmental factors, other native host species, and strength of association with domesticated Atlantic salmon.

Corridors best facilitate functional connectivity across a protected area network.

Biologging data allow animal ecologists to directly measure species' fine-scale spatiotemporal responses to environments, such as movement - critical for our understanding of biodiversity declines in the Anthropocene. Animal movement between resource patches is a behavioral expression of multiple ecological processes that affect individual fitness. Protected area (PA) networks are a tool used to conserve biodiversity by sustaining habitat patches across vast heterogeneous landscapes.

Cumulative effects of climate and landscape change drive spatial distribution of Rocky Mountain wolverine ( L.).

Contemporary landscapes are subject to a multitude of human-derived stressors. Effects of such stressors are increasingly realized by population declines and large-scale extirpation of taxa worldwide. Most notably, cumulative effects of climate and landscape change can limit species' local adaptation and dispersal capabilities, thereby reducing realized niche space and range extent.

The CF-CARES primary palliative care model: A CF-specific structured assessment of symptoms, distress, and coping.

Background: Current palliative care tools do not address distressing chronic symptoms that are most relevant to cystic fibrosis.

Methods: A CF-specific structured assessment based on a primary palliative care framework was administered to 41 adolescents and adults with CF. Descriptive and correlational analyses were conducted.

Wolverine behavior varies spatially with anthropogenic footprint: implications for conservation and inferences about declines.

Understanding a species' behavioral response to rapid environmental change is an ongoing challenge in modern conservation. Anthropogenic landscape modification, or "human footprint," is well documented as a central cause of large mammal decline and range contractions where the proximal mechanisms of decline are often contentious. Direct mortality is an obvious cause; alternatively, human-modified landscapes perceived as unsuitable by some species may contribute to shifts in space use through preferential habitat selection.

Synovial Sarcoma-AV Malformation Collision in the Anterior Mediastinum.

Arteriovenous malformation (AVM) and synovial sarcomas are both rare lesions in the mediastinum. Rarer still is a collision tumor in that region. Herein we present a case of a collision tumor comprised of AVM and synovial sarcoma in a 76-year-old man, presenting with pneumonia.

Pulmonary hemorrhage with capillaritis secondary to mycophenolate mofetil in a heart-transplant patient.

Immunosuppressive drugs are an integral part of therapy in organ transplantation. However, they are not without side effects, and although rare, these agents should be considered in the differential diagnosis of pulmonary complications in patients receiving transplants. We present a case of a patient who developed acute respiratory failure 7 days after orthotopic heart transplantation and who had been on both mycophenolate mofetil (MMF) and tacrolimus agents.

Body mass explains characteristic scales of habitat selection in terrestrial mammals.

Niche theory in its various forms is based on those environmental factors that permit species persistence, but less work has focused on defining the extent, or size, of a species' environment: the area that explains a species' presence at a point in space. We proposed that this habitat extent is identifiable from a characteristic scale of habitat selection, the spatial scale at which habitat best explains species' occurrence. We hypothesized that this scale is predicted by body size.

Fish farms, parasites, and predators: implications for salmon population dynamics.

For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural source of mortality of juvenile salmon. We examined how sea lice infestation affects predation risk and mortality of juvenile pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon, and developed a mathematical model to assess the implications for population dynamics and conservation.

Sea lice and salmon population dynamics: effects of exposure time for migratory fish.

The ecological impact of parasite transmission from fish farms is probably mediated by the migration of wild fishes, which determines the period of exposure to parasites. For Pacific salmon and the parasitic sea louse, Lepeophtheirus salmonis, analysis of the exposure period may resolve conflicting observations of epizootic mortality in field studies and parasite rejection in experiments. This is because exposure periods can differ by 2-3 orders of magnitude, ranging from months in the field to hours in experiments.

Epizootics of wild fish induced by farm fish.

The continuing decline of ocean fisheries and rise of global fish consumption has driven aquaculture growth by 10% annually over the last decade. The association of fish farms with disease emergence in sympatric wild fish stocks remains one of the most controversial and unresolved threats aquaculture poses to coastal ecosystems and fisheries. We report a comprehensive analysis of the spread and impact of farm-origin parasites on the survival of wild fish populations.

Transmission dynamics of parasitic sea lice from farm to wild salmon.

Marine salmon farming has been correlated with parasitic sea lice infestations and concurrent declines of wild salmonids. Here, we report a quantitative analysis of how a single salmon farm altered the natural transmission dynamics of sea lice to juvenile Pacific salmon. We studied infections of sea lice (Lepeophtheirus salmonis and Caligus clemensi) on juvenile pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta) as they passed an isolated salmon farm during their seaward migration down two long and narrow corridors.
