Artificial Intelligence Application to Pancreas Imaging
Despite the increasing rate of detection of incidental pancreatic cystic lesions (PCLs), current standard-of-care methods for their diagnosis and risk stratification remain inadequate. Intraductal papillary mucinous neoplasms (IPMNs) are the most prevalent PCLs. The existing modalities, including endoscopic ultrasound and cyst fluid analysis, only achieve accuracy rates of 65–75% in identifying carcinoma or high-grade dysplasia in IPMNs. Furthermore, surgical resection of PCLs reveals that up to half exhibit only low-grade dysplastic changes or benign neoplasms. To reduce unnecessary and high-risk pancreatic surgeries, more precise diagnostic techniques are necessary. A promising approach involves integrating existing data, such as clinical features, cyst morphology, and data from cyst fluid analysis, with confocal endomicroscopy and radiomics to enhance the prediction of advanced neoplasms in PCLs. Artificial intelligence and machine learning modalities can play a crucial role in achieving this goal.

Treatment of  Rheumatoid Arthritis
Rheumatoid arthritis refers to joint diseases of unclear etiology whose final stages can lead to unbearable pain and complete immobility of the affected joints. Modern treatment with anti-inflammatory drugs, including janus kinase (JAK) inhibitors, monoclonal antibodies, and botanicals (polyphenols, glycosides, alkaloids, etc.) has achieved some success and hope for improving the course of the disease.

Role of Genetics in Heart Failure Patients Management
The relevance of genetics in cardiovascular diseases has expanded, especially in the context of cardiomyopathies. Its relevance extends to the management of patients diagnosed with heart failure (HF), given its capacity to provide invaluable insights into the etiology of cardiomyopathies and identify individuals at a heightened risk of poor outcomes. Notably, the identification of an etiological genetic variant necessitates a comprehensive evaluation of the family lineage of the affected patients. In the future, these genetic variants hold potential as therapeutic targets with the capability to modify gene expression.

Sports Mouthguards
Mouthguards are classified into three groups according to their fabrication: stock, boil and bite, and custom-made. Additionally, they can be fabricated from various materials that can influence their effectiveness. Among the most commonly used materials for producing this device are polyvinyl acetate–polyethylene or ethylene vinyl acetate (EVA) copolymer, polyvinyl chloride, latex, acrylic resin, and polyurethane. Although using a mouthguard in sports activities is essential for preventing or reducing orofacial injuries, impacts affecting the rigid structure while using this device remain significant, especially in the anterior region of the maxilla.

Therapeutic Potential of Myrtenal and Its Derivatives
Myrtenal is a perspective monoterpenoid with therapeutic potential in various fields of medicine. Its chemical modifications often lead to new or more pronounced biological effects. As an example, the conjugation of myrtenal with the established pharmacophore adamantane enables the augmentation of several of its pivotal properties. Myrtenal–adamantane derivatives exhibited a variety of beneficial characteristics, such as antimicrobial, antifungal, antiviral, anticancer, anxiolytic, and neuroprotective properties, which are worth examining in more detail and at length.

Uterine Natural Killer Cells
Reproductive immunology is at the forefront of research interests, aiming to better understand the mechanisms of immune regulation during gestation. The relationship between the immune system and the implanting embryo is profound because the embryo is semi-allogenic but not targeted by the maternal immune system, as expected in graft-versus-host reactions. The most prominent cell population at the maternal–fetal interface is the population of uterine natural killer (uNK) cells. Uterine NK cells are two-faced immunologically active cells, bearing comparison with Janus, the ancient Roman god of beginnings and endings.

Surfactant Abnormalities in Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) is a major cause of hypoxemic respiratory failure in adults, leading to the requirement for mechanical ventilation and poorer outcomes. Dysregulated surfactant metabolism and function are characteristic of ARDS. A combination of alveolar epithelial damage leading to altered surfactant synthesis, secretion, and breakdown with increased functional inhibition from overt alveolar inflammation contributes to the clinical features of poor alveolar compliance and alveolar collapse.

Carrier-Mediated Delivery of Low-Molecular-Weight N-Containing Drugs
While it is true that pharmacotherapy has achieved desired health outcomes, significant unmet medical needs persist in the field of central nervous system (CNS) drugs, particularly for neurodegenerative diseases such as Alzheimer’s disease, as well as ocular diseases such as diabetic retinopathy and age-related macular degeneration. Drugs cannot enter the brain from the bloodstream due to the presence of the blood–brain barrier (BBB). Similarly, they cannot enter the eyes from the bloodstream due to the blood–retina barrier (BRB), which is composed of the endothelium or the epithelium. Thus, innovative drug delivery systems that can overcome these barriers based on efflux transporters, hydrophobic lipid bilayer membranes, and tight junctions should be developed using patient-friendly techniques distinct from craniotomy procedures or intravitreal injections. Brain-penetrating CNS drugs and antihistamine drugs commonly share N-containing groups. These findings suggest that certain types of cation transporters are involved in their transportation across the cell membrane.

Electrical Impedance Tomography
Electrical Impedance Tomography (EIT) is a non-invasive bedside imaging technique that provides real-time lung ventilation information on critically ill patients. EIT can potentially become a valuable tool for optimising mechanical ventilation, especially in patients with acute respiratory distress syndrome (ARDS).

Precision Medicine in Inflammatory Bowel Disease
Ulcerative colitis and Crohn’s disease are traditionally defined as the two main subtypes of inflammatory bowel disease. However, a more recent view considers inflammatory bowel diseases (IBDs) as a spectrum of heterogeneous phenotypes with consistent differences in clinical presentation and behaviors, likely explained by differences in underlying pathogenetic mechanisms. The etiology is still elusive, and the suggested pathogenesis is a complex interplay among genetic predisposition and abnormal immune response at the mucosal intestinal level, activated by only partially identified environmental triggers leading to altered intestinal permeability and impaired handling of gut microbiota. The undeniable continuous progress of medical therapy with more frequent shifts from traditional to more advanced modalities also underlines the actual unmet needs.
