Background: In patients with diabetes and multivessel coronary artery disease, percutaneous coronary intervention (PCI) has been associated with higher long-term cardiovascular mortality compared to coronary artery bypass grafting (CABG), but the specific causes of death are not well known. We aimed to determine the causes of death among patients with diabetes and multivessel disease undergoing coronary revascularization with PCI versus CABG.

Methods: We analyzed the centrally adjudicated causes of death of 1,900 participants in the FREEDOM trial.

Introduction: Recently, the FFR-Guidance for Complete Nonculprit Revascularization (FULL REVASC) trial in ST elevation myocardial infarction (STEMI) patients with multiple vessel disease (MVD) did not show differences in the composite endpoint of death from any cause, myocardial infarction, or unplanned revascularization than culprit-lesion-only percutaneous coronary intervention (PCI) at 4.8 years, although complete revascularization is a recommendation IA in current guidelines. We want to determine through an updated meta-analysis whether complete revascularization is associated with decreased mortality and hard clinical endpoints compared to culprit lesion only PCI.

Three-dimensional structured illumination microscopy (3D-SIM) and fluorescence in situ hybridization on three-dimensional preserved cells (3D-FISH) have proven to be robust and efficient methodologies for analyzing nuclear architecture and profiling the genome's topological features. These methods have allowed the simultaneous visualization and evaluation of several target structures at super-resolution. In this chapter, we focus on the application of 3D-SIM for the visualization of 3D-FISH preparations of chromosomes in interphase, known as Chromosome Territories (CTs).

The FA/BRCA pathway safeguards DNA replication by repairing interstrand crosslinks (ICL) and maintaining replication fork stability. Chromatin structure, which is in part regulated by histones posttranslational modifications (PTMs), has a role in maintaining genomic integrity through stabilization of the DNA replication fork and promotion of DNA repair. An appropriate balance of PTMs, especially acetylation of histones H4 in nascent chromatin, is required to preserve a stable DNA replication fork.

Background: Uncontrolled donation after circulatory death (uDCD) increases organ availability for kidney transplantation (KT) at the expense of a higher risk of primary graft nonfunction (PNF). At least half of the cases of PNF are secondary to graft venous thrombosis. The potential benefit from prophylactic anticoagulation in this scenario remains unclear.

The inherited bone marrow failure syndromes (IBMFSs) are a group of rare disorders characterized by bone marrow failure (BMF), physical abnormalities, and an increased risk of neoplasia. The National Institute of Pediatrics (INP) is a major medical institution in Mexico, where patients with BMF receive a complete approach that includes paraclinical tests. Readily recognizable features, such as the hematological and distinctive physical phenotypes, identified by clinical dysmorphologists, remain crucial for the diagnosis and management of these patients, particularly in circumstances where next-generation sequencing (NGS) is not easily available.

Cereals are the most important global staple crop and use more than half of global cropland and synthetic nitrogen (N) fertilizer. While this synthetic N may feed half of the current global population, it has led to a massive increase in reactive N loss to the environment, causing a suite of impacts, offsetting the benefits of N fertilizers for food security and agricultural economy. To address these complex issues, the NBCalCer model was developed to quantify the global effects of N input on crop yields, N budgets and environmental impacts and to assess the associated social benefits and costs.

Article Synopsis
  • Fanconi anemia (FA) is a rare genetic disorder with an incidence of 1:300,000, caused by mutations in genes related to DNA repair that lead to severe health issues, including bone marrow failure and increased cancer risk.
  • Individuals with FA often exhibit physical abnormalities at birth and face a heightened risk of developing squamous cell carcinoma (SCC) due to the limited effectiveness of traditional cancer treatments.
  • To address the challenges of studying FA due to its rarity, researchers propose using multi-level dynamical modeling based on comprehensive data from FA patients, aiming to understand tumorigenesis and improve predictive capabilities for better management and treatment strategies.

Double strand break (DSB) repair is critical to maintaining the integrity of the genome. DSB repair deficiency underlies multiple pathologies, including cancer, chromosome instability syndromes, and, potentially, neurodevelopmental defects. DSB repair is mainly handled by two pathways: highly accurate homologous recombination (HR), which requires a sister chromatid for template-based repair, limited to S/G2 phases of the cell cycle, and canonical non-homologous end joining (c-NHEJ), available throughout the cell cycle in which minimum homology is sufficient for highly efficient yet error-prone repair.

Along its route through the agro-food system nitrogen (N) can be wasted, heightening diverse environmental problems. Geopolitical instabilities affect prices of N fertilisers and livestock feed, challenging production systems and increasing their need to reduce N waste. The analysis of N flows is essential to understanding the agroenvironmental performance of agro-food systems to detect leakages and to design strategies for reducing N pollution while producing feed and food.

Despite the introduction of drug-eluting stents (DES) significantly improved the efficacy and safety of percutaneous coronary interventions (PCI), particularly in a high-risk group of patients, the gap between PCI with his competitor's coronary artery bypass surgery (CABG) and/or optimal medical treatment alone was not reduced. In this revision, we highlighted the fact that in recent years landmark randomized studies reported at mid and long-term follow-ups a high incidence of non-cardiac death, cancer incidence, or both in the DES group of patients. The overall incidence of non-cardiac death was significantly higher in the DES vs.
