Article Abstract
Background: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection.
Objective: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation.
Design And Setting: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul.
Methods: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed.
Results: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site.
Conclusion: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.

Potential Pharmacokinetic Interaction Between Enteral Nutrition and Valproic Acid.
Eur J Case Rep Intern Med

Background: Certain scientific publications suggest that medications with high protein binding, such as phenytoin, have lower-than-expected serum levels in patients receiving enteral nutrition (EN) preparations or nutritional supplements. Valproic acid (VPA) is highly protein bound but currently no interactions with EN that would reduce serum levels have been documented.
Case Description: A 69-year-old patient receiving enteral VPA oral solution via a nasojejunal tube experienced a clinically significant decrease in serum concentration when EN was initiated.

Ultra-sensitive pH-responsive drug delivery system designed to operate within the slightly acidic microenvironment of tumors are highly desired for hydrogel applications in cancer therapy. In this study, 4-Formylbenzoic acid modified polyvinyl alcohol (PVA-FBA, PF) was synthesized and utilized as a carrier for encapsulating the anticancer drug Doxorubicin (Dox). This was subsequently crosslinked with polyethylenimine (PEI) via benzoic-imine bond to form drug-loaded PVA-FBA/PEI hydrogel (D-PFP).

Goal-directed behavior requires adjusting cognitive control, both in preparation for and in reaction to conflict. Theta oscillations and population activity in dorsomedial prefrontal cortex (dmPFC) and dorsolateral PFC (dlPFC) are known to support reactive control. Here, we investigated their role in proactive control using human intracranial electroencephalogram (EEG) recordings during a Stroop task that manipulated conflict expectations.

Introduction: The airway mucosa plays a crucial role in protection and various physiological functions. Current methods for restoring airway mucosa, such as myocutaneous flaps or split skin grafts, create a stratified squamous layer that lacks the cilia and mucus-secreting glands of the native columnar-lined airway. This study examines the application of various injectable biopolymers as active molecules for a potential approach to regenerating laryngeal epithelial tissue.

Polyunsaturated fatty acids (PUFAs), fatty acids with multiple unsaturated carbon-carbon bonds, constitute a crucial class of lipids. While the vast diversity of PUFA species arises from their structural variations, most of them are poorly investigated due to their limited availability. Here, we utilize solid-phase synthesis of PUFAs, which we have recently developed, to construct a PUFA library.
