Will climate warming amplify the effects of a range-expanding marine predator?

The effects of climate warming on the distribution of range-expanding species are well documented, but the interactive effects of climate warming and range-expanding species on recipient communities remain understudied. With climate warming, range-expanding species may threaten local biodiversity due to their relatively stronger competitive or predatory effects on potentially weakened, or less well-adapted recipient communities. Acanthinucella spirata is a predatory marine gastropod that has expanded its distribution north along the California coast since the Pleistocene via a poleward range shift, tracking climatic warming.

Social worlds of Appalachian women caregivers of older relatives living with dementia.

Rationale: Over 11 million people in the United States provide care for an older family member with dementia, with this responsibility primarily falling on daughters and wives. In Appalachia, a mountainous region in the U.S characterized by close families, family members were crucial to ensuring that care needs were met for people living with dementia during the COVID-19 pandemic.

Co-creation experiences among adults in diverse contexts: A Health CASCADE scoping review.

Objectives: This scoping review aimed to summarise available evidence relating to co-creation experiences among adults in diverse contexts. Understanding how participation in co-creation processes shapes experiences is important as it can offer insights into the improved development and effective use of such processes. Co-creation has increasingly gained attention due to its many claimed advantages and benefits to participants.

Adult co-creators' emotional and psychological experiences of the co-creation process: a Health CASCADE scoping review protocol.

Background: There is a growing investment in the use of co-creation, reflected by an increase in co-created products, services, and interventions. At the same time, a growing recognition of the significance of co-creators' experience can be detected but there is a gap in the aggregation of the literature with regard to experience. Therefore, the purpose of this scoping review is to uncover the breadth of existing empirical research on co-creation experience, how it has been defined and assessed, and its key emotional and psychological characteristics in the context of co-created products, services, or interventions among adults.

Structural Magnetic Resonance Imaging-Based Surface Morphometry Analysis of Pediatric Down Syndrome.

Down syndrome (DS) is a genetic disorder characterized by intellectual disability whose etiology includes an additional partial or full copy of chromosome 21. Brain surface morphometry analyses can potentially assist in providing a better understanding of structural brain differences, and may help characterize DS-specific neurodevelopment. We performed a retrospective surface morphometry study of 73 magnetic resonance imaging (MRI) examinations of DS patients (aged 1 day to 22 years) and compared them to a large cohort of 993 brain MRI examinations of neurotypical participants, aged 1 day to 32 years.

Natural selection on feralization genes contributed to the invasive spread of wild pigs throughout the United States.

Despite a long presence in the contiguous United States (US), the distribution of invasive wild pigs (Sus scrofa × domesticus) has expanded rapidly since the 1980s, suggesting a more recent evolutionary shift towards greater invasiveness. Contemporary populations of wild pigs represent exoferal hybrid descendants of domestic pigs and European wild boar, with such hybridization expected to enrich genetic diversity and increase the adaptive potential of populations. Our objective was to characterize how genetic enrichment through hybridization increases the invasiveness of populations by identifying signals of selection and the ancestral origins of selected loci.

Population genomics provide insight into ancestral relationships and diversity of the feral horses of Theodore Roosevelt National Park.

Theodore Roosevelt National Park (TRNP) manages a herd of feral horses () which was present on the landscape prior to the establishment of the park. The population presents a unique scenario in that it has experienced fairly intensive and well-documented management since the park's establishment, including herd size reductions, intentional introduction of diversity, and subsequent attempts to remove introduced lineages. This provides an interesting case study on the genetic effects of diverse evolutionary forces on an isolated feral population.

Acute sensorimotor paraneoplastic neuropathy in a patient with small cell prostate cancer.

The authors describe a patient with a background of metastatic small cell prostate cancer who presented with a rapidly evolving sensorimotor neuropathy with bulbar features closely resembling Guillain-Barré syndrome, with a good initial response to intravenous immunoglobulins and platinum-based chemotherapy. This represented a likely paraneoplastic manifestation of the patient's urological malignancy.

Family Caregivers' Management of Behavioral Expressions of Dementia.

Background And Objectives: Behavioral expressions of dementia are often stressful for family caregivers to manage as they strive to ensure their relative's needs are met. Guided by Lazarus and Folkman's Transactional Model of Stress and Coping, we identified specific behaviors that disrupt daily routines and challenge the achievement of caregiving goals, and the approaches and strategies caregivers employ to address them.

Research Design And Methods: We conducted semistructured interviews with 30 family caregivers in rural Appalachia caring for a relative living with dementia.

Time for You: A process evaluation of the rapid implementation of a multi-level mental health support intervention for frontline workers during the COVID-19 pandemic.

The coronavirus (COVID-19) pandemic had wide-ranging negative impacts on mental health. The pandemic also placed extraordinary strain on frontline workers who were required to continue working and putting themselves at risk to provide essential services at a time when their normal support mechanisms may not have been available. This paper presents an evaluation of the Time for You service, a rapidly developed and implemented intervention aimed at providing frontline workers with quick access to flexible online mental health support.

A short multi-factor screening tool to assess falls-risk in older people presenting to an Australian emergency department: A feasibility study.

Objective: The purpose of this study was to evaluate use of a short multi-factor falls-risk screening tool for older people within the emergency department, to enable rapid identification of falls-risk and triggers for multidisciplinary referral for further falls-specific assessment.

Methods: Older people, aged ≥70 years, presenting to the emergency department with a fall-related injury or disease (n = 137) were recruited by a research nurse following randomisation. A short multi-factor screening tool was completed, comprised of 14 falls-risk-related assessment components.

The Association of Nonmodifiable Patient Factors on Antipsychotic Medication use in the Intensive Care Unit.

Purpose: We investigated the association of age, sex, race, and insurance status on antipsychotic medication use among intensive care unit (ICU) patients.

Materials And Methods: Retrospective study of adults admitted to ICUs at a tertiary academic center. Patient characteristics, hospital course, and medication (olanzapine, quetiapine, and haloperidol) data were collected.

Conserved and Divergent Features of pH Sensing in Major Fungal Pathogens.

Purpose Of Review: For human fungal pathogens, sensory perception of extracellular pH is essential for colonisation of mammalian tissues and immune evasion. The molecular complexes that perceive and transmit the fungal pH signal are membrane-proximal and essential for virulence and are therefore of interest as novel antifungal drug targets. Intriguingly, the sensory machinery has evolved divergently in different fungal pathogens, yet spatial co-ordination of cellular components is conserved.

Chromosome-level reference genome for North American bison (Bison bison) and variant database aids in identifying albino mutation.

We developed a highly contiguous chromosome-level reference genome for North American bison to provide a platform to evaluate the conservation, ecological, evolutionary, and population genomics of this species. Generated from a F1 hybrid between a North American bison dam and a domestic cattle bull, completeness and contiguity exceed that of other published bison genome assemblies. To demonstrate the utility for genome-wide variant frequency estimation, we compiled a genomic variant database consisting of 3 true albino bison and 44 wild-type pelage color bison.

Feasibility and Acceptability of LNG 1.5 mg as an On-Demand Pericoital Contraceptive in Ghana.

Globally, there is a need for more family planning method options as currently, available options do not adequately meet the needs of women, specifically those who have infrequent sex. Levonorgestrel (LNG) 1.5 mg is widely available as emergency contraception pills (ECP), and recent research has shown that certain women take it as their main form of contraception.

Mitogenomes revealed the history of bison colonization of Northern Plains after the Last Glacial Maximum.

American bison demonstrated differential patterns of extinction, survival, and expansion since the terminal Pleistocene. We determined population dynamics of the Northern Great Plains bison using 40 mitochondrial genomes from radiocarbon dated remains with the age ranging from 12,226 to 167 calibrated years before present. Population dynamics correlated with environmental and anthropogenic factors and was characterized by three primary periods: terminal Pleistocene population growth starting 14,000 years ago, mid Holocene demographic stability between 6700 and 2700 years ago, and late Holocene population decline in the last 2700 years.

Prevalence of Different Approaches to Clinical Hypnosis: .

A recent survey conducted by the Society of Clinical and Experimental Hypnosis Task Force for Efficacy Standards in Hypnosis Research found that clinicians reported using one or more of several different styles of hypnosis in their work. The most common of these was Ericksonian, used by over 2/3rds of clinicians, followed by hypnotic relaxation therapy and traditional hypnosis. Surprisingly, a little less than a 3rd of respondents indicated using the evidence-based practice of hypnotherapy.

Developing novel antifungals: lessons from G protein-coupled receptors.

Up to 1.5 million people die yearly from fungal disease, but the repertoire of antifungal drug classes is minimal and the incidence of drug resistance is rising rapidly. This dilemma was recently declared by the World Health Organization as a global health emergency, but the discovery of new antifungal drug classes remains excruciatingly slow.
