While previous foraging studies have identified key variables that determine attentional selection, they are affected by the global statistics of the tasks. In most studies, targets are selected one at a time without replacement while distractor numbers remain constant, steadily reducing the ratios of targets to distractors with every selection. We designed a foraging task with a sequence of local "snapshots" of foraging displays, with each snapshot requiring a target selection.

Increasing extreme climatic events threaten the functioning of terrestrial ecosystems. Because soil microbes govern key biogeochemical processes, understanding their response to climate extremes is crucial in predicting the consequences for ecosystem functioning. Here we subjected soils from 30 grasslands across Europe to four contrasting extreme climatic events under common controlled conditions (drought, flood, freezing and heat), and compared the response of soil microbial communities and their functioning with those of undisturbed soils.

Phenomics

August 2024

Mental Health Center and West China Biomedical Big Data Center, West China Hospital, Sichuan University, Guo Xue Lane 37, Chengdu, 610000 China.

Unlabelled: Whether associations between psychiatric disorders and hospitalization for cardiovascular diseases (CVDs) can be modified by disease susceptibility and the temporal pattern of these associated CVDs remain unknown. In our study, we conducted a matched cohort study of the UK Biobank including 44,430 patients with common psychiatric disorders (anxiety, depression, and stress-related disorders) between 1997 and 2019, together with 222,150 sex-, Townsend deprivation index-, and birth year- individually matched unexposed individuals. The hazard ratios (HRs) for CVD hospitalization associated with a prior psychiatric disorder were derived from Cox models, adjusted for multiple confounders.

What are the diagnostic dimensions on which objects differ visually? We constructed a two-dimensional object space based on such attributes captured by a deep convolutional neural network. These attributes can be approximated as stubby/spiky and animate-/inanimate-looking. If object space contributes to human visual cognition, this should have a measurable effect on object discrimination abilities.

Introduction: Risk minimisation measures (RMMs) aim to ensure safe use of medicines, but their implementation in clinical practice is complicated by the diversity of stakeholders whose clinical decision making they seek to inform. Clinical practice guidelines (CPGs) are considered integral in clinical decision making.

Objectives: To determine the extent to which RMMs are included in the relevant CPGs and to describe factors that determine RMM inclusion.

Article Synopsis
  • - This study aimed to find the best time for labor induction in normotensive singleton pregnancies to reduce risks like stillbirth, analyzing 70,293 births in Iceland from 1997 to 2018 while excluding high-risk cases.
  • - Results showed that inducing labor at or after 40 weeks decreased cesarean rates without increasing adverse outcomes, while earlier inductions did not show significant benefits.
  • - The conclusion emphasized that inducing labor post-40 weeks is safer for women without heightening risks for mothers or babies, and earlier induction in low-risk pregnancies isn’t beneficial.

Considerations in the search for epistasis.

Genome Biol

November 2024

Commonwealth Scientific and Industrial Research Organisation, Westmead, Australia.

Epistasis refers to changes in the effect on phenotype of a unit of genetic information, such as a single nucleotide polymorphism or a gene, dependent on the context of other genetic units. Such interactions are both biologically plausible and good candidates to explain observations which are not fully explained by an additive heritability model. However, the search for epistasis has so far largely failed to recover this missing heritability.

Background: Families are an important part of the intensive care unit (ICU) team. Being a family member in the ICU can be distressing due to interacting factors, such as the critical condition of the patient, the responsibility of acting as the patient's advocate, and partaking in decision-making related to treatment. Nurses need to be aware of the family's well-being throughout the patient's ICU stay.

How does color distribution learning affect goal-directed visuomotor behavior?

Cognition

January 2025

Icelandic Vision Lab, Faculty of Psychology, School of Health Sciences, University of Iceland, Reykjavik, Iceland. Electronic address:

While the visual world is rich and complex, importantly, it nevertheless contains many statistical regularities. For example, environmental feature distributions tend to remain relatively stable from one moment to the next. Recent findings have shown how observers can learn surprising details of environmental color distributions, even when the colors belong to actively ignored stimuli such as distractors in visual search.

The genome of esophageal adenocarcinoma (EAC) is highly unstable and might evolve over time. Here, we track karyotype evolution in EACs in response to treatment and upon recurrence through multi-region and longitudinal analysis. To this end, we introduce L-PAC (low-purity inference of absolute copy-number alterations [CNAs]), a bio-informatics technique that allows inference of absolute CNAs of low-purity samples by leveraging the information of high-purity samples from the same cancer.
