Assessment of Eosinophilic Esophagitis
Eosinophilic esophagitis (EoE) is an immune-mediated disease that manifests with dysphagia and is characterized by the predominantly eosinophilic infiltration of the esophageal mucosa. Several instruments have been developed to assess the symptoms of EoE.

Hepatitis B Surface Antigen Isoforms
The hepatitis B surface antigen (HBsAg) is a multifunctional glycoprotein composed of large (LHB), middle (MHB), and small (SHB) subunits. HBsAg isoforms have numerous biological functions during HBV infection—from initial and specific viral attachment to the hepatocytes to initiating chronic infection with their immunomodulatory properties. Their immunogenic properties make them a major target for developing HBV vaccines, and they have been recognised as valuable targets for new therapeutic approaches. In addition, HBsAg isoform quantitation can become a useful non-invasive biomarker for assessing chronically infected patients.

Congestion in Heart Failure
Annual heart failure hospitalizations exceed 1 million in both the United States and Europe, and more than 90% are due to symptoms and signs of fluid overload. Additionally, up to one in four patients (24%) are readmitted within 30 days, and one in two patients (50%) are readmitted within 6 months. Acute decompensated heart failure (ADHF) remains the leading cause of hospitalization in patients > 65 years old and has the highest rate of 30-day rehospitalization among all medical conditions. Recurrent fluid overload in heart failure has been associated with worse outcomes independently of age and renal function. Deranged hemodynamics, neurohormonal activation, excessive tubular sodium reabsorption, inflammation, oxidative stress, and nephrotoxic medications are important drivers of harmful cardiorenal interactions in patients with heart failure. Central venous pressure elevation is rapidly transmitted to the renal veins, causing increased interstitial and tubular hydrostatic pressure, which decreases net glomerular filtration. Venous congestion itself can produce endothelial activation, the up-regulation of inflammatory cytokines, hepatic dysfunction, and intestinal villi ischemia. Thus, the foremost goal in managing acutely decompensated heart failure is to effectively resolve fluid overload.

Antiphospholipid Mediated Arteriovenous Fistula Complications
Antiphospholipid antibody (aPL)-persistent positivity is frequent in hemodialysis (HD) patients. Native arteriovenous fistula (AVF) complications such as stenosis and thrombosis are among the most important causes of morbidity and mortality in hemodialysis patients. The association between aPL positivity and AVF thrombosis seems to be well established.

Pathophysiological Mechanisms of the Podocytopathies
Nephrotic syndrome (NS) is a clinical entity characterized by the triad of proteinuria, hypoalbuminemia, and edema. The main pathophysiological alteration in NS is the impairment of the glomerular filtration barrier. Therefore, its permeability becomes non-selective, and urinary protein loss occurs. Being the final barrier to protein loss in the glomerulus, alterations in podocyte structure can explain why injuries in these cells, such as the effacement of their foot processes, are typically related to proteinuria and hypoalbuminemia and, therefore, to the conditions under the NS umbrella.

Coronary Artery Disease in the Lung Transplant Patient
Lung transplantation can greatly improve quality of life and extend survival in those with end-stage lung disease. In order to derive the maximal benefit from such a procedure, patients must be carefully selected and be otherwise healthy enough to survive a high-risk surgery and sometimes prolonged immunosuppressive therapy following surgery. Patients therefore must be critically assessed prior to being listed for transplantation with close attention paid towards assessment of cardiovascular health and operative risk. One of the biggest dictators of this is coronary artery disease.

Rehabilitation Training after Spinal Cord Injury Affects Brain
Spinal cord injury (SCI) is a serious neurological insult that disrupts the ascending and descending neural pathways between the peripheral nerves and the brain, leading to not only functional deficits in the injured area and below the level of the lesion but also morphological, structural, and functional reorganization of the brain. These changes introduce new challenges and uncertainties into the treatment of SCI. Rehabilitation training, a clinical intervention designed to promote functional recovery after spinal cord and brain injuries, has been reported to promote activation and functional reorganization of the cerebral cortex through multiple physiological mechanisms.

MSC-Based Therapies in Post-Acute Neurological COVID Syndrome
One of the main concerns related to SARS-CoV-2 infection is the symptoms that could be developed by survivors, known as long COVID, a syndrome characterized by persistent symptoms beyond the acute phase of the infection. This syndrome has emerged as a complex and debilitating condition with a diverse range of manifestations affecting multiple organ systems. It is increasingly recognized for affecting the Central Nervous System, in which one of the most prevalent manifestations is cognitive impairment. The search for effective therapeutic interventions has led to growing interest in Mesenchymal Stem Cell (MSC)-based therapies due to their immunomodulatory, anti-inflammatory, and tissue regenerative properties.

Gut and Oral Microbiota in Intracranial Aneurysms
There has been a growing interest in the role of the microbiome in cardiovascular and cerebrovascular diseases. Emerging research highlights the potential role of the microbiome in intracranial aneurysm (IA) formation and rupture, particularly in relation to inflammation.

p38 as Molecular Target in Multiple Myeloma Therapy
Resistance to therapy and disease progression are the main causes of mortality in most cancers. In particular, the development of resistance is an important limitation affecting the efficacy of therapeutic alternatives for cancer, including chemotherapy, radiotherapy, and immunotherapy. Signaling pathways are largely responsible for the mechanisms of resistance to cancer treatment and progression, and multiple myeloma is no exception. p38 mitogen-activated protein kinase (p38) is downstream of several signaling pathways specific to treatment resistance and progression.
