Background: Isolated subsegmental pulmonary embolism (issPE) is a commonly encountered diagnosis. Although the International Classification of Diseases (ICD)-10 codes are used for research, their validity for identifying issPE is unknown. Moreover, issPE diagnosis is challenging, and the findings from radiology reports may conflict with those from expert radiologists.

Background: Echocardiographic evaluation of vegetations is crucial in infective endocarditis (IE). Although several studies have noted a link between larger vegetations and an increased risk of embolization, a more comprehensive evaluation of vegetation characteristics in a contemporary cohort has not been conducted. Our study aimed to define the short-term risk of symptomatic embolization in patients with IE.

Background: The use of potentially inappropriate medications (PIMs) is a major concern for medication safety as it may entail more harm than potential benefits for older adults. This study aimed to explore the prescribing rate, healthcare utilization, and expenditure of older adults using PIMs in China.

Methods: A cross-sectional analysis was conducted using a national representative database of all medical insurance beneficiaries across China, extracting ambulatory visit records of adults aged 65 years and above between 2015 and 2017.

Introduction: This study aimed to identify cognitive tests that optimally relate to tau positron emission tomography (PET) signal in the inferior temporal cortex (ITC), a neocortical region associated with early tau accumulation in Alzheimer's disease (AD).

Methods: We analyzed cross-sectional data from the harvard aging brain study (HABS) (= 128) and the Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) study (= 393). We used elastic net regression to identify the most robust cognitive correlates of tau PET signal in the ITC.

The biological mechanisms underlying women's increased Alzheimer's disease (AD) prevalence remain undefined. Previous case/control studies have identified sex-biased molecular pathways, but sex-specific relationships between gene expression and AD endophenotypes, particularly sex chromosomes, are underexplored. With bulk transcriptomic data across 3 brain regions from 767 decedents, we investigated sex-specific associations between gene expression and post-mortem β-amyloid and tau as well as antemortem longitudinal cognition.

The "" under this Perspective underline the importance of interdisciplinary collaboration and partnerships across several disciplines, such as medical science and technology, medicine, bioengineering, and computational approaches, in bridging the gap between research, manufacturing, and clinical applications. Effective communication is key to bridging team gaps, enhancing trust, and resolving conflicts, thereby fostering teamwork and individual growth toward shared goals. Drawing from the success of the COVID-19 vaccine development, we advocate the application of similar collaborative models in other complex health areas such as nanomedicine and biomedical engineering.

Revising EU pharmaceutical legislation: will it foster drug repurposing?

Drug Discov Today

January 2025

Department of Clinical Epidemiology & Medical Technology Assessment (KEMTA), Maastricht University Medical Centre, Maastricht, the Netherlands; Care and Public Health Research Institute (CAPHRI), Maastricht University, Maastricht, the Netherlands; REPO4EU consortium.

Repurposing off-patent drugs can be a potential source of low-cost treatments for patients with unmet medical needs. Here, we review the proposed new European Union (EU) pharmaceutical legislation in which two articles address drug repurposing. We find certain barriers hindering the adoption of these new incentives by academic and not-for-profit stakeholders, including lack of knowledge on regulatory aspects, pharmacovigilance, and restrictions in data protection.

Revisiting Injectable Estrogen Dosing Recommendations for Gender-Affirming Hormone Therapy.

Transgend Health

December 2024

Division of Endocrinology, Metabolism and Diabetes, Department of Medicine, University of Colorado School of Medicine, Anschutz Medical Campus, Aurora, Colorado, USA.

Injectable estrogens are options for gender-affirming hormone therapy per guidelines, which suggest intramuscular dosages of 5-30 mg every 2 weeks or 2-10 mg weekly with estradiol cypionate or valerate interchangeably. Data among transgender and gender-diverse patients are limited due to local unavailability and concerns around laboratory assay variability and estradiol (E2) level fluctuation. We note a concerning trend where patients are prescribed high-dose injections based on the guidelines leading to serum E2 levels well above the range recommended in the same guidelines.

Cardiovascular diseases (CVDs) and cerebrovascular diseases (CeVDs) are closely related vascular diseases, sharing common cardiometabolic risk factors (RFs). Although pleiotropic genetic variants of these two diseases have been reported, their underlying pathological mechanisms are still unclear. Leveraging GWAS summary data and using genetic correlation, pleiotropic variants identification, and colocalization analyses, we identified 11 colocalized loci for CVDs-CeVDs-BP (blood pressure), CVDs-CeVDs-LIP (lipid traits), and CVDs-CeVDs-cIMT (carotid intima-media thickness) triplets.

The native extracellular matrix is continuously remodeled to form complex interconnected network structures that reversibly regulate stem cell behaviors. Both regulation and understanding of its intricate dynamicity can help to modulate numerous cell behaviors. However, neither of these has yet been achieved due to the lack of designing and modeling such complex structures with dynamic controllability.

Aims/hypothesis: Vitamin D insufficiency is associated with an elevated risk of type 2 diabetes, but evidence from randomised trials on the benefits of vitamin D supplementation is limited, especially for average-risk populations. The Finnish Vitamin D Trial (FIND) investigated the effects of vitamin D supplementation at two different doses on the incidence of type 2 diabetes in a generally healthy older adult population.

Methods: FIND was a 5 year randomised placebo-controlled, parallel-arm trial among 2271 male and female participants aged ≥60 years and ≥65 years, respectively, from a general Finnish population who were free of CVD or cancer and did not use diabetes medications.

Article Synopsis
  • The study examines the long-term outcomes of patients with univentricular heart and total cavopulmonary connection Fontan, focusing on those with hypoplastic left heart syndrome (HLHS) compared to other types.
  • The research found that patients with HLHS experienced a significantly higher incidence of adverse cardiovascular events, including death and transplantation, with a hazard ratio indicating over six times the risk.
  • The findings suggest that HLHS is a critical factor in determining poorer outcomes in patients with this heart condition.

Directed protein evolution is central to biomedical applications but faces challenges such as experimental complexity, inefficient multiproperty optimization, and local maxima traps. Although in silico methods that use protein language models (PLMs) can provide modeled fitness landscape guidance, they struggle to generalize across diverse protein families and map to protein activity. We present EVOLVEpro, a few-shot active learning framework that combines PLMs and regression models to rapidly improve protein activity.

Vaccine-based therapeutics for cancers face several challenges including lack of immunogenicity and tumor escape pathways for single antigen targets. It has been reported that radiotherapy has an in situ vaccine effect that provides tumor antigens following irradiation, helping to activate antigen-presenting cells (APCs). Herein, a new vaccine approach is developed by combining genetically engineered irradiated tumor cell debris (RTD) and hyaluronic acid (HA), termed HA@RTD.
