AI-powered fraud and the erosion of online survey integrity: an analysis of 31 fraud detection strategies.

The proliferation of AI-powered bots and sophisticated fraudsters poses a significant threat to the integrity of scientific studies reliant on online surveys across diverse disciplines, including health, social, environmental and political sciences. We found a substantial decline in usable responses from online surveys from 75 to 10% in recent years due to survey fraud. Monetary incentives attract sophisticated fraudsters capable of mimicking genuine open-ended responses and verifying information submitted months prior, showcasing the advanced capabilities of online survey fraud today.

Deep Learning Resolves Myovascular Dynamics in the Failing Human Heart.

The adult mammalian heart harbors minute levels of cycling cardiomyocytes (CMs). Large numbers of images are needed to accurately quantify cycling events using microscopy-based methods. CardioCount is a new deep learning-based pipeline to rigorously score nuclei in microscopic images.

Survival after partial heart transplantation in a piglet model.

Partial heart transplantation (PHT) is a novel surgical approach that involves transplantation of only the part of the heart containing a valve. The rationale for this approach is to deliver growing heart valve implants that reduce the need for future re-operations in children. However, prior to clinical application of this approach, it was important to assess it in a preclinical model.

Surgical Protocol for Partial Heart Transplantation in Growing Piglets.

Partial heart transplantation is a new approach to deliver growing heart valve implants. Partial heart transplants differ from heart transplants because only the part of the heart containing the necessary heart valve is transplanted. This allows partial heart transplants to grow, similar to the valves in heart transplants.

A variety-specific analysis of climate change effects on California winegrapes.

California contains a broad geography over which climate conditions can be suitable for cultivating multiple varieties of winegrapes. However, climate change is projected to make winegrape cultivation more challenging across many of California's winegrowing regions. In order to understand the potential effects of climate change on winegrapes, this study models variety-specific phenology for six winegrape varieties and quantifies the change in phenology and viticulturally-important agroclimate metrics over 12 of California's American Viticultural Areas (AVAs) by the mid-21st century.

Qualitative Analysis of Implementation Factors of an Embedded Caregiver Support Intervention into Adult Day Services.

Background: Adult day services (ADS) are an important and often underutilized support resource for older adults. For persons living with dementia (PLWD), ADS is an optimal access point to not only receive therapeutic and rehabilitative activities, but as a vehicle for respite/relief for dementia caregivers. Yet, there is currently a lack of research on integrating caregiver interventions into home and community-based services such as ADS.

Days alive and out of hospital for children born with single-ventricle heart disease.

Background: This study describes the illness burden in the first year of life for children with single-ventricle heart disease, using the metric of days alive and out of hospital to characterize morbidity and mortality.

Methods: This is a retrospective single-centre study of single-ventricle patients born between 2005 and 2021 who had their initial operation performed at our institution. Patient demographics, anatomical details, and hospitalizations were extracted from our institutional single-ventricle database.

Use of microaxial flow pumps in adolescents.

Objectives: The Impella 5.5 has been successfully used in the adult population; however, safety and efficacy data in patients aged less than 18 years are limited.

Methods: Six pediatric patients, aged 13 to 16 years and weighing 45 to 113 kg, underwent axillary artery graft placement and attempted placement of the Impella 5.

Responding to the HIV Health Literacy Needs of Clients in Substance Use Treatment: The Role of Universal PrEP Education in HIV Health and Prevention.

Health literacy, particularly HIV health literacy, is a key social determinant of health and can be significantly improved through targeted health education. This paper explores the often-overlooked potential of pre-exposure prophylaxis (PrEP) education as a powerful tool to enhance HIV health literacy among people with substance use disorders (PWSUD), a population notably susceptible to HIV. Given the syndemic interplay of substance use disorders (SUDs) and HIV, health professionals, especially substance use counselors, are uniquely positioned to bolster HIV health literacy and positively influence health outcomes.

Climate change impacts on insect pests for high value specialty crops in California.

California is a global leader in production and supply of walnuts and almonds, and the state is the largest producer of peaches in the U.S. These crops have an important contribution to the California's agricultural economy.

The intersection of social determinants of health and family care of people living with Alzheimer's disease and related dementias: A public health opportunity.

In this Perspective article, we highlight current research to illustrate the intersection of social determinants of health (SDOHs) and Alzheimer's disease and related dementia (ADRD) caregiving. We then outline how public health can support ADRD family caregivers in the United States. Emerging research suggests that family care for persons with ADRD is influenced by SDOHs.

Using Hybrid Effectiveness Studies to Facilitate Implementation in Community-Based Settings: Three Case Studies in Dementia Care Research.

The pipeline from discovery to testing and then implementing evidence-based innovations in real-world contexts may take 2 decades or more to achieve. Implementation science innovations, such as hybrid studies that combine effectiveness and implementation research questions, may help to bridge the chasm between intervention testing and implementation in dementia care. This paper describes hybrid effectiveness studies and presents 3 examples of dementia care interventions conducted in various community-based settings.

Embedding Caregiver Support Within Adult Day Services: Outcomes of a Multisite Trial.

Background And Objectives: Adult day services (ADS) provide quality-of-life benefits to people with dementia, but few provide systematic caregiver support. We report outcomes of a multisite, national trial testing a staff-delivered caregiver program, ADS Plus.

Research Design And Methods: Cluster-randomized trial involving 34 ADS: 18 sites provided ADS (controls) and 16 provided ADS and ADS Plus (intervention).

: A Web-Based Precision Medicine Tool for Predicting Variant Pathogenicity in Cardiomyopathy- and Channelopathy-Associated Genes.

Background: With genetic testing advancements, the burden of incidentally identified cardiac disease-associated gene variants is rising. These variants may carry a risk of sudden cardiac death, highlighting the need for accurate diagnostic interpretation. We sought to identify pathogenic hotspots in sudden cardiac death-associated genes using amino acid-level signal-to-noise (S:N) analysis and develop a web-based precision medicine tool, , to improve variant evaluation.

Deletion Is Associated With Sex-dependent Cardiomyopathy and Cardiac Mortality: A Translational, Multi-Institutional Cohort Study.

Background: 1p36 deletion syndrome can predispose to pediatric-onset cardiomyopathy. Deletion breakpoints are variable and may delete the transcription factor . Early studies suggest that deletion of may underlie cardiomyopathy in patients with 1p36 deletion; however, the prognostic impact of loss is unknown.

Induced Pluripotent Stem Cell-Based Modeling of Single-Ventricle Congenital Heart Diseases.

Purpose Of Review: Congenital heart disease includes a wide variety of structural cardiac defects, the most severe of which are single ventricle defects (SVD). These patients suffer from significant morbidity and mortality; however, our understanding of the developmental etiology of these conditions is limited. Model organisms offer a window into normal and abnormal cardiogenesis yet often fail to recapitulate complex congenital heart defects seen in patients.
