Cardiopulmonary Exercise Testing in Heart Failure
C is a valuable and versatile tool used in the classification of HF; these tests characterize the dynamic interactions between the cardiovascular, respiratory, and metabolic systems during physical exertion. This testing involves the systematic measurement of respiratory gases, heart rate, and other physiological parameters during controlled exercise. This non-invasive assessment provides a comprehensive evaluation of exercise capacity and helps identify abnormalities in cardiopulmonary function that may not be apparent at rest.

Diabetic Gastroparesis
Diabetic gastroparesis (DGP) is a debilitating gastrointestinal disorder characterized by delayed gastric emptying in individuals with diabetes mellitus, particularly type 1 and long-standing type 2 diabetes. This condition, although not widely known, significantly impacts the quality of life of affected individuals. The symptoms of DGP, including early satiety, excessive fullness after meals, loss of appetite, bloating, abdominal pain, and vomiting, stem from the slowed or stalled movement of food from the stomach to the small intestine.

Autophagy in Uveal Melanoma
Autophagy is a form of programmed cell degradation that enables the maintenance of homeostasis in response to extracellular stress stimuli. Autophagy is primarily activated by starvation and mediates the degradation, removal, or recycling of cell cytoplasm, organelles, and intracellular components in eukaryotic cells. Autophagy is also involved in the pathogenesis of human diseases, including several cancers. Autophagy mechanisms and mediators have emerged as promising therapeutic targets that could be used to develop new treatment options for uveal melanoma (UM).

Endoscopic Transpapillary/Endoscopic Ultrasound-Guided Gallbladder Drainage of Acute Cholecystitis
A percutaneous cholecystostomy tube (PCT) is the conventionally favored nonoperative intervention for treating acute cholecystitis. However, PCT is beset by high adverse event rates, need for scheduled reintervention, and inadvertent dislodgement, as well as patient dissatisfaction with a percutaneous drain. Recent advances in endoscopic therapy involve the implementation of endoscopic transpapillary drainage (ETP-GBD) and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD), which are increasingly preferred over PCT due to their favorable technical and clinical success combined with lower complication rates.

Nuclear Factor-Kappa B Pathway in SARS-CoV-2 Infection
COVID-19 is a global health threat caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is associated with a significant increase in morbidity and mortality. As a central player in the immune and inflammatory responses, modulating NF-κB activation could offer a strategic avenue for managing SARS-CoV-2 infection.

Entero-Cutaneous and Entero-Atmospheric Fistulas
Enteric fistulas are a common problem in gastrointestinal tract surgery and remain associated with significant mortality rates, due to complications such as sepsis, malnutrition, and electrolyte imbalance. The increasingly widespread use of open abdomen techniques for the initial treatment of abdominal sepsis and trauma has led to the observation of so-called entero-atmospheric fistulas. Because of their clinical complexity, the proper management of enteric fistula requires a multidisciplinary team. The main goal of the treatment is the closure of enteric fistula, but also mortality reduction and improvement of patients’ quality of life are fundamental. Successful management of patients with enteric fistula requires the establishment of controlled drainage, management of sepsis, prevention of fluid and electrolyte depletion, protection of the skin, and provision of adequate nutrition.

Percutaneous Biliary Drainage
Ultrasound guidance in biliary interventions has become the standard tool to facilitate percutaneous biliary drainage as well as percutaneous gall bladder drainage. Monitoring of the needle tip whilst penetrating the tissue in real time using ultrasound allows precise manoeuvres and exact targeting without radiation exposure.

Influence of Ultra-Processed Food on Colorectal Cancer
Colorectal cancer (CRC) is a disease characterised by the development of malignant tumours in the colon or rectum; it is considered the most common cancer in women, and up to 50% of cases can be prevented with a healthy lifestyle. Nutritional habits are related to its appearance, and the trend of an increased consumption of ultra-processed foods (UPFs) has led to a surge in the incidence of CRC.

Bioprinting of Hydrogel-Based Drug Delivery Systems
Globally, thousands of people are affected by severe nerve injuries or neurodegenerative disorders. These conditions cannot always be cured because nerve tissue either does not regenerate or does so at a slow rate. Therefore, tissue engineering has emerged as a potential treatment approach. The combination of bioprinting, hydrogels, and drug delivery effectively addresses key issues in nerve tissue regeneration.

Vasoactive Intestinal Peptide Family Members in Diabetic Keratopathy
Diabetic keratopathy (DK) is a common ocular complication of diabetes, characterized by alteration of the normal wound-healing mechanism, reduction of epithelial hemidesmosomes, disruption of the basement membrane, impaired barrier function, reduced corneal sensitivity, corneal ulcers, and corneal edema.
