Insulin secretion significantly decreased after treatment by senescent microvesicles (P3 1.7 ± 0.2 vs untreated islet 2.7 ± 0.2, P < .05) without altering the islet viability (89.47% ± 1.69 vs 93.15% ± 0.97) and with no significant apoptosis. Senescent microvesicles significantly doubled the expression of p53, p21, and p16 (P < .05), whereas young microvesicles had no significant effect.

Pro-senescent endothelial microvesicles specifically accelerate the senescence of islets and alter their function. These data suggest that islet isolation contributes to endothelial driven islet senescence.

Burn injury continues to cause significant morbidity and mortality in the US pediatric population. Many studies using inpatient samples have found a relationship between low socioeconomic status (SES) and burn injury. The purpose of our study was to evaluate the association between SES and the likelihood of admission for Emergency Department (ED) visits for pediatric burn injury.

A retrospective database review of pediatric ED visits for burn injury from a statewide hospital system, from January 1, 2005 to December 31, 2014. SES was assigned using an eight factor Neighborhood Risk Index (NRI) created from census block group data, with a higher score indicative of lower SES. The outcome measure was ED visits admitted to inpatient care.

We analyzed a sample of 1845 pediatric ED visits for burn injuries. Most visits were discharged from the ED (88.4%) while 10.5% were admitted to inpatient care and 1.0% were transferred to another hospital. In a multivariable logistic regression model, patients from high risk areas (>75th percentile NRI) had 1.58 higher odds of inpatient admission compared to patients from low risk areas (<75th percentile NRI; 95% CI 1.08-2.30), after adjusting for age, gender, ethnicity, distance to the hospital, and previous ED visit for burn injury in the past 30 days. In addition, for every 1-mile increase in distance, a child's likelihood of admission increased by 6% (95% CI 4-9%).

Children with a burn injury from the highest risk socioeconomic areas in Rhode Island had a higher likelihood of inpatient admission. Further research is needed to determine what factors associated with socioeconomic status impact this finding.

In some cases, the tongue and oesophagus tissues are damaged by the corrosive burn. Surgical interventions may cause scar formation, and severe burns treatment methods are limited. This study aims to investigate bromelain, a phytotherapeutic product, on the corrosive burn as a non-surgical option and as an adjunctive therapy, insofar as the treatment of corrosive wounds is not limited only to the treatment of oxidative stress and inflammatory reactions.

On the tongues of Wistar albino rats, chemically produced oral ulcers were created by topical application of NaOH (40%) solution, and in the distal oesophagus same mixture was applied to produce a corrosive oesophageal burn. For a week, they were treated orally by bromelain (100 mg/kg/day) or saline solution. At the end of seven days, animals were decapitated to remove the tongue and oesophagus, and blood samples were collected to obtain serum. Myeloperoxidase (MPO) activity, malondialdehyde (MDA), glutathione (GSH), interleukin-1 beta (IL-1β) and tumour necrosis factor-alpha (TNF-α) concentrations were measured in serum, and luminol and lucigenin chemiluminescence (CL) were measured in tissue samples.

MDA and CL values were significantly increased, and GSH levels in tissue significantly decreased due to the corrosive burns. Saline treated corrosive burn group measured higher in the serum cytokines in according to the control group.

Bromelain administration decreased oxidant and inflammatory parameters and increased antioxidant levels in NaOH-induced corrosive burns. Thus, we concluded that bromelain may protect the tongue and oesophagus tissues with its anti-inflammatory and antioxidant effects.

Clinical data of 324 patients with extensive burns treated at our department from July 2014 to December 2019 were retrospectively analyzed. Approximately half of the patients (50.93%) exhibited elevated serum PCT concentrations during the early phase, and elevated PCT levels may not be caused by infections. Early-phase PCT level was an independent risk factor for sepsis occurrence in extensive-burn patients within 60 days of injury. read more Burn index, degree of inhalation injury, and APACHE-II score influenced PCT level elevation during the early phase. Patient age, burn index, APACHE-II score at admission, early-phase PCT level, and sepsis occurrence were risk factors for mortality in extensive-burn patients. During the early phase, approximately 50.93% of the extensive-burn patients exhibited elevated PCT levels, which were associated with non-infectious factors. As elevated PCT level during the early phase predicted sepsis occurrence within 60 days of injury and was significantly associated with patient mortality, it might be a potential burn severity indicator during the early phase of burn injury.

Stereophotogrammetry (SPG) provides a more objective measurement of burn wound area than traditional clinical assessments. The recently developed Intel® RealSense™ D415/Wound Measure SPG system has yet to undergo formal evaluation in a paediatric population.

A pilot study comparing the Intel® RealSense™ D415/Wound Measure to the previously validated LifeVizII®/DermaPix® SPG system, for burn assessment was conducted at a tertiary paediatric burn centre. Both systems were used to photograph and analyse the same acute wounds for each patient. Three independent raters measured wound area and perimeter. Level of agreement between systems and raters was estimated by calculating the intra-class correlation coefficient.

Wound area measurements were completed in both systems for 25 burns from 13 patients (median age, 2 years). The participants were mainly female (n = 9), with a median TBSA-B of 9% (IQR 3-20%). There was strong agreement between the systems 0.757 (95% CI 0.521, 0.885, p < 0.001). Within each SPG system, there was excellent inter-rater reliability.
