Obtaining robust estimates of population abundance is a central challenge hindering the conservation and management of many threatened and exploited species. Close-kin mark-recapture (CKMR) is a genetics-based approach that has strong potential to improve the monitoring of data-limited species by enabling estimates of abundance, survival, and other parameters for populations that are challenging to assess. However, CKMR models have received limited sensitivity testing under realistic population dynamics and sampling scenarios, impeding the application of the method in population monitoring programs and stock assessments.

Variation in fitness components can be linked in some cases to variation in key traits. Metric traits that lie at the intersection of development, defense, and ecological interactions may be expected to experience environmental selection, informing our understanding of evolutionary and ecological processes. Here, we use quantitative genetic and population genomic methods to investigate disease dynamics in hybrid and non-hybrid populations.

The conservation and management of wildlife populations, particularly for threatened and endangered species are greatly aided with abundance, growth rate, and density measures. Traditional methods of estimating abundance and related metrics represent trade-offs in effort and precision of estimates. Pedigree reconstruction is an emerging, attractive alternate approach because its use of one-time, noninvasive sampling of individuals to infer the existence of unsampled individuals.

Organismal thermal limits affect a wide range of biogeographical and ecological processes. Copepods are some of the most abundant animals on the planet and play key roles in aquatic habitats. Despite their abundance and ecological importance, there is limited data on the factors that affect copepod thermal limits, impeding our ability to predict how aquatic ecosystems will be affected by anthropogenic climate change.

Article Synopsis
  • [18F]AZD4694 is an imaging agent for amyloid beta that has been studied but lacks published longitudinal data on Aβ accumulation.
  • A study of 146 participants found that cognitively unimpaired older adults showed slight increases in Aβ accumulation over two years, with greater increases seen in those who were Aβ positive.
  • The findings suggest that [18F]AZD4694 could effectively track amyloid levels in both research and clinical contexts, particularly before beginning treatments targeting amyloid.

Key Clinical Message: This report described the pathophysiology, diagnostic workup, and management of thrombosis possibly associated with peripheral blood eosinophilia and transient positive antiphospholipid antibodies in the setting of cellulitis.

Abstract: Peripheral blood eosinophilia is a risk factor for thrombosis and the presence of other prothrombotic factors such as antiphospholipid antibodies can potentiate that risk. The authors present a case of acute pulmonary embolism which developed at the peak of eosinophilia, later found to have transient positive antiphospholipid antibodies in a male patient with right lower limb cellulitis and a history of intravenous drug abuse.

Objectives: Head and neck cancer (HNC) patients experience greater financial toxicity than other cancer patients. Research on financial toxicity has concentrated on patients despite many informal caregivers sharing finances and reducing work hours to provide patient care. Thus, our pilot study: (1) assessed the feasibility of financial toxicity screening of HNC patients and their caregivers, and (2) described financial toxicity levels of HNC patients and their caregivers.

Kinship-based methods of population assessment such as close-kin mark-recapture require accurate and efficient genotyping methods capable of resolving complex relationships among kin. Inference of such relationships can be difficult using biallelic loci due to the large number of markers required to obtain the necessary power. Sequencing-based microsatellite panels offer an efficient alternative, combining high polymorphism with efficient next-generation methods.

Background: Approximately 1 in 4 athletes returning to sports will sustain a second anterior cruciate ligament (ACL) injury. Psychological factors related to kinesiophobia, confidence, and psychological readiness are associated with second ACL injury; however, the evidence is conflicting.

Hypothesis: Athletes who sustain a second ACL injury (ie, graft rupture or contralateral ACL rupture) within 2 years of ACL reconstruction (ACLR) would have greater kinesiophobia, less confidence, and lower psychological readiness prior to return to sport (RTS) compared with athletes who do not sustain a second ACL injury.

Objectives: The American Academy of Otolaryngology clinical practice guidelines recommend cross-sectional imaging or fine needle aspiration for any neck mass in an adult that persists beyond 2 weeks that is not convincingly related to a bacterial infection. We aimed to assess the role of ultrasound in the evaluation and management of neck masses.

Methods: A retrospective chart review was performed of adult patients evaluated in the Otolaryngology clinic at a single institution from December 2014 to December 2015 for a visible or palpable neck mass persistent beyond 2 weeks who had an ultrasound exam as part of their initial workup.

Clinical genetic evaluations are defined by the knowledge and technology available at the time they occur. In the modern era, microarray and exome sequencing are first line tests for clinical geneticists; however, beginning in the late 1970s and continuing until the turn of the past century, a standard genetic evaluation consisted, in many cases, of an examination by a dysmorphologist as well as a conventional karyotype. In general, once a genetic diagnosis is established, it does not get revisited as more advanced methods become available.

Pesticide resistance provides one of the best examples of rapid evolution to environmental change. The Colorado potato beetle (CPB) has a long and noteworthy history as a super-pest due to its ability to repeatedly develop resistance to novel insecticides and rapidly expand its geographic and host plant range. Here, we investigate regional differences in demography, recombination, and selection using whole-genome resequencing data from two highly resistant CPB populations in the United States (Hancock, Wisconsin and Long Island, New York).

Background Monocytes/macrophages participate in cardiovascular disease. CD163 (cluster of differentiation 163) is a monocyte/macrophage receptor, and the shed sCD163 (soluble CD163) reflects monocyte/macrophage activation. We examined the association of sCD163 with incident cardiovascular disease events and performed a genome-wide association study to identify sCD163-associated variants.

A growing body of work examines the direct and indirect effects of climate change on ecosystems, typically by using manipulative experiments at a single site or performing meta-analyses across many independent experiments. However, results from single-site studies tend to have limited generality. Although meta-analytic approaches can help overcome this by exploring trends across sites, the inherent limitations in combining disparate datasets from independent approaches remain a major challenge.

Introduction: We examine whether the association between key plasma biomarkers (amyloid β [aβ] 42/40, total tau (t-tau), neurofilament light [NfL]) and cognitive trajectories (executive function [EF] and episodic memory [EM]) is mediated through neurodegeneration.

Methods: All participants were recruited from the University of California, Davis-Alzheimer's Disease Research Center ( = 473; baseline age range = 49-95 years, 60% women). We applied an accelerated longitudinal design to test latent growth models for EF and EM, and path and mediation analyses.
