CFD Analysis in LAA Thrombus Formation Risk
Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular and rapid electrical activity in the atria, leading to ineffective contraction and poor blood flow. More than 90% of the left atrial (LA) thrombi that cause thromboembolic events during atrial fibrillation (AF) develop in the left atrial appendage (LAA). Computational fluid dynamics (CFD) analysis can be used to better understand the risk of thrombus formation and subsequent embolic events.

Effect of Honey on Human Health
Honey is a nutritious, healthy, and natural food, to which antioxidant, anti-inflammatory, and antimicrobial properties have been attributed, mainly due to its content of phenolic compounds. More beneficial effects of honey intake than no or negative effects on different cardiovascular and metabolic risk factors, glucose tolerance, mucositis caused by chemo-radiotherapy, cough in children and wound healing, among others have been observed. Although the number of studies conducted to date is limited and the different investigations are not standardized, beneficial effects of honey intake have been observed, especially when its intake replaces the intake of other sweeteners. Therefore, honey could be a safe adjuvant to be administered to people aged more than 1 year old alongside drugs currently used for certain diseases. However, it should not be forgotten that honey is a high sugar food, and it should be consumed occasionally and with moderation. More studies are necessary to establish more specific recommendations on honey consumption.

Effect of Fortified Cocoa-Based Products with Cocoa Flavanols
Cocoa’s healthy benefits may be attributed to the potent antioxidant activity of cocoa polyphenols, mainly flavanols, which have been characterised as existing in a high concentration in cocoa. However, the phenolic composition of cocoa and cocoa-derived products is highly variable, and manufacturing processes might significantly reduce their phenolic content. For that reason, the full characterisation of cocoa and cocoa-derived products before evaluating their bioactivity is crucial. Although studies differ widely in methodology, dosage, duration, and target population, beneficial effects of flavanol-rich cocoa consumption have been observed at doses ranging from 45.3 mg/d to 1078 mg/d, especially on cardiovascular health and cognitive function. It should be noted that some cocoa-derived products contain added sugars and additional fats that could have harmful effects, so consumption of such products should be occasional and moderate. It is also for this reason that the fortification of such products with cocoa flavanols could be effective in enhancing their beneficial effects whilst maintaining a lower level of consumption.

Mitochondrial Integrity in Right Heart Failure Development
Molecular processes underlying right ventricular (RV) dysfunction (RVD) and right heart failure (RHF) need to be understood to develop tailored therapies for the abatement of mortality of a growing patient population. Today, the armament to combat RHF is poor, despite the advancing identification of pathomechanistic processes. Mitochondrial dysfunction implying diminished energy yield, the enhanced release of reactive oxygen species, and inefficient substrate metabolism emerges as a potentially significant cardiomyocyte subcellular protagonist in RHF development. Dependent on the course of the disease, mitochondrial biogenesis, substrate utilization, redox balance, and oxidative phosphorylation are affected.

Clinical Application of Hypoxia-Inducible Factor-1α Inhibitors
Hypoxia is a common phenomenon amongst physiological and pathological conditions, and is a strong stressor for cells and organisms, which can lead to metabolic disorders, and even cause cell death. Hypoxia-inducible factor-1α (HIF-1α) is the only transcription factor that has been found to be active under hypoxia, and is also the main nuclear transcription factor that mediates the adaptive response to hypoxia in mammals. It is closely related to the growth and development of organisms and the pathogenesis of some diseases. HIF-1α has low expression in the human brain, lung, placenta, heart, skeletal muscle, kidney, and pancreas under normoxia, but there is an exponentially large increase of HIF-1α in the brain, lung, kidney, heart, and other tissues under hypoxia. HIF-1α inhibitors can be widely used in the treatment of various diseases related to HIF-1 overexpression, such as tumors; leukemia; diabetes and its complications; ischemic, cardiovascular and brain diseases; and inflammatory diseases, etc.

Hypoxia in Cardiovascular Diseases
Heart valve diseases are a major contributor to cardiovascular morbidity and mortality worldwide. They affect more than 13% of the population aged over 75 years old and occur when any type of the four heart valves (tricuspid, pulmonic, mitral, and aortic valves) is damaged. Calcific aortic valve disease (CAVD) is defined as a slowly progressing condition that ranges from mild valve aortic sclerosis to severe calcifying aortic valve stenosis. This progression manifests in approximately 2% of individuals over 65 years old annually.

Applications of Computed Tomography in Peripheral Artery Disease
Peripheral artery disease (PAD) is a common and debilitating condition characterized by the narrowing of the limb arteries, primarily due to atherosclerosis. Non-invasive multi-modality imaging approaches using computed tomography (CT), magnetic resonance imaging (MRI), and nuclear imaging have emerged as valuable tools for assessing PAD atheromatous plaques and vessel walls.

Artificial Intelligence Applications in Interstitial Lung Diseases
Interstitial lung diseases (ILDs) comprise a rather heterogeneous group of diseases varying in pathophysiology, presentation, epidemiology, diagnosis, treatment and prognosis. In the majority of ILDs, imaging modalities and especially high-resolution Computed Tomography (CT) scans have been the cornerstone in patient diagnostic approach and follow-up. The intricate nature of ILDs and the accompanying data have led to an increasing adoption of artificial intelligence (AI) techniques, primarily on imaging data but also in genetic data, spirometry and lung diffusion, among others.

Quantum Theory and the Mind
Quantum theory, which is focused on the physical laws that govern structures such as the nucleus of an atom or even the subatomic particles within an atomic nucleus, has properties that make it unique to most other areas of physics. Quantum theory tends to give unique, discrete energy states by defining a wave function with given boundary conditions using Erwin Schrödinger’s wave equation, helping calculate and determine the specific energy states, amongst other specific quantities this wave function would be likely to have. Quantum theory disconnects itself from the normal classical theories of physics in that it does not treat variables along a continuous spectrum, but rather finds discrete states which these variables can be expected to have.

Colorectal Cancer Epidemiology
Early onset colorectal cancer (EOCRC) is defined as CRC diagnosed in individuals younger than 50, which is generally considered the ideal age to start screening programs in the average-risk population. Although the overall incidence of colorectal cancer (CRC) is declining, the number of new diagnoses in patients younger than 50 is alarmingly increasing.
