Objective: Burns are among the most common injuries in children. In burns of more than 20% of the total body surface area, a systemic inflammatory response involving several chemical mediators occurs. Among them, nerve growth factor (NGF) regulates the inflammatory response related to wound healing and promotes keratinocyte proliferation and angiogenesis. The aim of our study was to investigate the physiological response to injury in children with moderate-severe burns, assaying proNGF, mature NGF (mNGF), interleukins (IL)-1β, and Il-10 serum levels.
Patients And Methods: This is a prospective observational study, including twelve children hospitalized for moderate-severe burns at the Gemelli Hospital (Rome). Their laboratory features were compared to those of patients with obstructive hydrocephalus who underwent surgery.
Results: Our results showed an increase in proNGF and mNGF serum levels. In burn patients, proNGF levels increased before mNGF, and serum concentrations of both were not correlated with burn extension and depth. The most significant levels of mNGF and proNGF were reported in scalds involving the face. Serum IL-1β and IL-10 peak levels were reached with a time-course pattern similar to proNGF.
Conclusions: Our preliminary results validate the hypothesis that serum levels of proNGF and mNGF may represent inflammatory biomarkers useful for monitoring burn patients and defining new strategies for their treatment.

Background: Fibromyalgia Syndrome (FMS) is a chronic disabling musculoskeletal condition of unknown aetiology characterized by generalized musculoskeletal pain, extreme fatigue, mood disturbance, impaired cognition, and lack of refreshing sleep. Middle East pain syndrome (MEPS) is a newly described pollution-induced syndrome of hyperparathyroidism and fibromyalgia mimicking rheumatoid arthritis, characterized by the radiological presence of spur-like excrescences in terminal phalanges. This study aimed to explore the inflammatory nature of Middle East pain and Fibromyalgia syndromes.

Background: Recent advancements in contemporary therapeutic approaches have increased the survival rates of lung cancer patients; however, the long-term benefits remain constrained, underscoring the pressing need for novel biomarkers. Surfactant-associated 3 (SFTA3), a long non-coding RNA predominantly expressed in normal lung epithelial cells, plays a crucial role in lung development. Nevertheless, its function in lung adenocarcinoma (LUAD) remains inadequately understood.
