Predictors of Gambling Severity Among Female Gamblers: Cross-Country Study with Spanish and Italian Clinical Population.

J Gambl Stud

January 2025

Department of Psychology, Faculty of Health Sciences, University of Deusto, Avda. de las Universidades, 24, Bilbao, 48007, Spain.

A large body of research has evidenced different risk factors associated with the severity of gambling. However, most of the research has been conducted with a male population, and consequently it has been inferred that the female population presents the same experiences and characteristics. Research on female gamblers is limited, with the result that their gambling-related problems are not effectively addressed.

Background: Flat epithelial atypia (FEA), a rare breast proliferative lesion, is often diagnosed following core biopsy (CB) of mammographic microcalcifications. In the prospective multi-institution TBCRC 034 trial, we investigate the upgrade rate to ductal carcinoma in situ (DCIS) or invasive cancer following excision for patients diagnosed with FEA on CB.

Patients And Methods: Patients with a breast imaging reporting and data system (BI-RADS) ≤ 4 imaging abnormality and a concordant CB diagnosis of FEA were identified for excision.

CircRNA-loaded DC vaccine in combination with low-dose gemcitabine induced potent anti-tumor immunity in pancreatic cancer model.

Cancer Immunol Immunother

January 2025

National Engineering Laboratory for AIDS Vaccine, School of Life Science, Jilin University, Changchun, China.

Although promising, dendritic cell (DC) vaccines may not suffice to fully inhibit tumor progression alone, mainly due to the short expression time of the antigen in DC vaccines, immunosuppressive tumor microenvironment, and tumor antigenic modulation. Overcoming the limitations of DC vaccines is expected to further enhance their anti-tumor effects. In this study, we constructed a circRNA-loaded DC vaccine utilizing the inherent stability of circular RNA to enhance the expression level and duration of the antigen within the DC vaccine.

The identification of cancer driver genes is crucial for understanding the complex processes involved in cancer development, progression, and therapeutic strategies. Multi-omics data and biological networks provided by numerous databases enable the application of graph deep learning techniques that incorporate network structures into the deep learning framework. However, most existing methods do not account for the heterophily in the biological networks, which hinders the improvement of model performance.

Alzheimers Dement

December 2024

Faculdade de Medicina de Ciências Médicas de Minas Gerais, Belo Horizonte, Brazil.

Background: Most research initiatives have emerged from high-income countries (HIC), leaving a gap in understanding the disease's genetic basis in diverse populations like those in Latin American countries (LAC). ReDLat tackles this gap, focusing on LAC's unique genetics and socioeconomic factors to identify specific Alzheimer's Disease (AD) and Frontotemporal Dementia (FTD) risk factors in Mexico, Colombia, Peru, Chile, Argentina, and Brazil.

Method: We employed a comprehensive genetic analysis approach, integrating Whole Genome Sequencing (WGS), Exome Sequencing, and SNP arrays to understand the cohort's unique genetic architecture.

Background: Subjective cognitive decline (SCD) is recognized to be in the Alzheimer's disease (AD) cognitive continuum. An international working group known as the SCD-initiative recently proposed "SCD plus" features, including report of memory problems, recent SCD relative to conversion, SCD over age 60, and consistent SCD over time, that increase the risk for future objective cognitive decline. These have not been fully assessed in a large community-based setting.

The global chaos caused by the July 19, 2024 technology meltdown highlights the need for a theory of what large-scale cohesive behaviors-dangerous or desirable-could suddenly emerge from future systems of interacting humans, machinery, and software, including artificial intelligence; when they will emerge; and how they will evolve and be controlled. Here, we offer answers by introducing an aggregation model that accounts for the interacting entities' inter- and intraspecies diversities. It yields a novel multidimensional generalization of existing aggregation physics.

Background: Febrile young infants are at risk of invasive bacterial infections (IBIs; bacteremia or bacterial meningitis). American Academy of Pediatrics (AAP) guidelines recommend that when procalcitonin testing is unavailable, C-reactive protein (CRP), absolute neutrophil count (ANC) and temperature should be used to identify low-risk infants. We sought to determine the optimal combination of these inflammatory markers to predict IBI when procalcitonin is unavailable.

Office of the Assistant Secretary for Health, United States Department of Health and Human Services, Washington, DC 20201, United States.

Objective: Timely access to data is needed to improve care for substance-exposed birthing persons and their infants, a significant public health problem in the United States. We examined the current state of birthing person and infant/child (dyad) data-sharing capabilities supported by health information exchange (HIE) standards and HIE network capabilities for data exchange to inform point-of-care needs assessment for the substance-exposed dyad.

Material And Methods: A cross-map analysis was performed using a set of dyadic data elements focused on pediatric development and longitudinal supportive care for substance-exposed dyads (70 birthing person and 110 infant/child elements).

STIMULUS research group, Vrije Universiteit Brussel, Jette, Belgium; Cluster Neurosciences, Center for Neurosciences (C4N), Vrije Universiteit Brussel, Brussels, Belgium; Pain in Motion Research Group (PAIN), Department of Physiotherapy, Human Physiology and Anatomy, Faculty of Physical Education & Physiotherapy, Vrije Universiteit Brussel, Jette, Belgium; Department of Neurosurgery, Universitair Ziekenhuis Brussel, Jette, Belgium; Center for Neurosciences (C4N), Vrije Universiteit Brussel, Jette, Belgium; Research Foundation Flanders (FWO), Brussels, Belgium; Department of Radiology, Universitair Ziekenhuis Brussel, Jette, Belgium.

Objective: Patients with therapy-refractory chronic spinal pain after spinal surgery experience increased disability, resulting in substantial loss of employment and consequently lower quality of life. Despite findings that rehabilitation improves socio-economic outcomes in other chronic pain conditions, evidence for patients with chronic spinal pain after spinal surgery is limited. A systematic review was conducted to provide an overview of rehabilitation interventions and their effectiveness to improve work participation for patients with chronic spinal pain after spinal surgery.

Severe fever with thrombocytopenia syndrome virus (SFTSV) is a tick-borne virus with a human mortality rate of up to 30%, posing a significant threat to public health. However, the lack of suitable research models has impeded the development of effective human vaccines. In this study, we engineered transgenic mice (3xTg) using a novel construct that simultaneously expresses three C-type Lectin receptors, identified as critical SFTSV entry receptors.

Genomics-based timely detection of dengue virus type I genotypes I and V in Uruguay.

Heliyon

November 2024

Laboratorio de Virus Emergentes/reemergentes. Unidad de Virología, Departamento de Laboratorios de Salud Pública, Portugal.

This study details a genomics-based approach for the early detection of mosquito-borne pathogens, marked by Uruguay's first ever complete genomic sequencing of Dengue Virus type I genotypes I and V. This pioneering effort has facilitated the prompt identification of these genotypes within the country, enabling Uruguayan public health authorities to develop timely and effective response strategies. Further integrated into this approach is a climate-driven suitability measure, closely associated with Dengue case reports and indicative of the local climate's role in the virus's transmission in the country within the changing climate context.

This study evaluates the deposition of diamond-like carbon (DLC) films with copper impurities on a glass substrate using simultaneous direct current (DC) and radio frequency (RF) magnetron sputtering. The structural, optical, electrical, and mechanical properties, as well as the surface topography of the films, were investigated under various DC power levels using Raman spectroscopy, ellipsometry, UV-VIS, I-V measurements, nanoindentation, AFM, and FESEM. Results indicate that increasing the DC power to the graphite target from 60 to 120 , while maintaining a constant 10  of RF power to the copper target, enhances the optical absorption coefficient of the films and increases the optical bandgap from 0.
