Wounds are conditions largely present in the clinical routine, and even though frequent, their complete resolution can be challenging. Several solutions can aid or stimulate the healing process, and for this reason, this work used a stabilized solution of 4% sodium hypochlorite for the treatment of excisional wounds in mice. This study was carried out in two distinct stages in the first stage, the optimal concentration of the chlorinated solution was determined by using the sponge implantation technique in mouse subcutaneous tissue to evaluate the dose-response curve; and in the second phase, this concentration was tested in an experimental model of excisional skin wounds in mice. Soluble collagen, hemoglobin, myeloperoxidase (MPO) and N-acetyl-β-D-glycosaminidase (NAG) activity were assessed, and total, type I and type III collagen deposition were quantified in both stages. Based on the results presented in the sponge implantation study, the chlorinated solution at 150 ppm (0.015%) was chosen for use in a preclinical trial of skin healing in mice. At 1, 3, 7 and 14 days of treatment, the % wound area repair in the group treated with 150 ppm chlorinated solution was higher when compared to the control group, with statistical differences at all time points (*p≤ 0.05 and **p≤ 0.01). 150 ppm chlorinated solution obtained from a stabilized 4% sodium hypochlorite solution was effective in accelerating cutaneous excision wound repair in mice, showing a positive influence on tissue repair.

Use of an LMA ProSeal™ laryngeal mask airway (P-LMA; Teleflex) with no neuromuscular block is considered a safe alternative to tracheal intubation in short-duration paediatric laparoscopic surgery. However, few studies have evaluated surgical conditions of short-duration paediatric laparoscopic surgery using this anaesthetic technique. We assessed surgical conditions for paediatric laparoscopic inguinal hernia repair using P-LMA with and without neuromuscular block.

Sixty-six patients undergoing laparoscopic inguinal hernia repair were randomised to receive a neuromuscular block (train-of-four 1-2 twitches) using rocuronium or no neuromuscular block with the P-LMA. All operations were performed by the same surgeon who determined the surgical conditions using the Leiden-surgical rating scale (L-SRS). Secondary outcomes included perioperative data, haemodynamics, and adverse events.

Neuromuscular block improved surgical conditions compared with no neuromuscular block mean (standard deviation) L-SRS 4.1 (0.5) vs 3.5 (0.6), respectively (P<0.0001). Mean rocuronium dose in the neuromuscular block group was 12.7 (4.4-29.7) mg or 0.7 (0.6-0.8) mg kg

. The insufflation Ppeak was higher in the no neuromuscular block group than in the neuromuscular block group mean (standard deviation) Ppeak 17.9 (1.8) cm H

O vs 16.2 (1.9) cm H

O, respectively (P=0.0004). Fifteen children (45.5%) in the no neuromuscular block group had adverse events during the surgery and anaesthesia vs four children (12.1%) in the neuromuscular block group (P=0.006).

Neuromuscular block significantly improved surgical conditions and reduced the incidence of adverse events during surgery and anaesthesia when an LMA Proseal™ was used in short-duration paediatric laparoscopic surgery.

The overall goal of this study was to determine the effects of MnSOD-deficiency on vascular structure and function in hypercholesterolemic mice. Previous work suggested that increases in mitochondrial-derived reactive oxygen species (ROS) can exacerbate vascular dysfunction and atherosclerosis. It remains unknown, however, how MnSOD-deficiency and local compensatory mechanisms impact atherosclerotic plaque composition.

We used a hypercholesterolemic mouse model (ldlr

/ApoB

 ; LA), either wild-type for MnSOD (LA-MnSOD

) or MnSOD-haploinsufficient (LA-MnSOD

), that was fed a western diet for either 3 or 6 months. Consistent with previous reports, reductions of MnSOD did not significantly worsen hypercholesterolemia-induced endothelial dysfunction in the aorta. Critically, dramatic impairment of vascular function with Nox2 inhibition or catalase pretreatment suggested the presence of a significant NO-independent vasodilatory mechanism in LA-MnSOD

mice (e.g. H

). Despite remarkably well-preserved oveeterious in the context of vascular calcification.

The aim of this study was to examine the association between food insecurity and untreated caries among US children and the potential role of diet quality as a mediator in this relationship.

The authors analyzed data for 4,822 children aged 5 through 17 years from the National Health and Nutrition Examination Survey cycles from 2011 through 2014. SKF96365 in vitro The authors measured food security as household-level food security status (full, marginal, low, very low) and overall food security status (full food secure, food insecure). They measured diet quality using the Healthy Eating Index. The primary outcome measure was untreated caries (none, ≥1). The authors used multiple logistic regression analysis to evaluate the relationships among food insecurity, diet quality, and untreated caries. They conducted mediation analysis using the Baron and Kenny approach.

Food-insecure children were more likely to have untreated caries compared with their fully food-secure counterparts, after controlling for confounding variables (odds ratio [OR], 1.38; 95% [CI, 1.11 to 1.72). Specifically, children from marginal and very low food-secure households had significantly higher odds of untreated caries (OR, 1.48; 95% CI, 1.10 to 2.01) compared with children from fully food-secure households (OR, 1.59; 95% CI, 1.12 to 2.26). Diet quality was not significantly associated with untreated caries.

Food insecurity was negatively associated with untreated caries among US children. Diet quality was not associated with untreated caries.

Social factors such as food insecurity should be taken into consideration when dental clinicians perform caries risk assessment because caries risk is shown to be associated with overall health and dental health.
