Methods are proposed which permit estimating bioresistance of protective materials against denitrifying hydrocarbon-oxidizing and sulphate-reducing bacteria-destructors of coatings in laboratory conditions. The methods are based on the quantitative determination of bacteria growth in presence of coatings as the only source of hydrocarbon. Besides, attention is given to changes of certain indices of physico-mechanical properties of coatings: breaking strength and adhesion strength for coatings from polymeric bands, softening and expansion temperature for mastic materials.

National early warning score 2 plus non-invasive capnography and perfusion index to estimate poor outcomes in emergency departments.
Am J Emerg Med
January 2025
Faculty of Medicine, Universidad de Valladolid, Valladolid, Spain; Emergency Department, Hospital Clínico Universitario, Gerencia Regional de Salud de Castilla y León, Valladolid, Spain.
Background: The study of the inclusion of new variables in already existing early warning scores is a growing field. The aim of this work was to determine how capnometry measurements, in the form of end-tidal CO2 (ETCO2) and the perfusion index (PI), could improve the National Early Warning Score (NEWS2).
Methods: A secondary, prospective, multicenter, cohort study was undertaken in adult patients with unselected acute diseases who needed continuous monitoring in the emergency department (ED), involving two tertiary hospitals in Spain from October 1, 2022, to June 30, 2023.
Objective: While the association of a syrinx with a tethered spinal cord in the context of VACTERL (vertebral defects [V], imperforate anus or anal atresia [A], cardiac malformations [C], tracheoesophageal defects [T] with or without esophageal atresia [E], renal anomalies [R], and limb defects [L]) association is known, the incidence of idiopathic syrinxes among these patients has not previously been reported. The authors aimed to characterize the incidence of syrinxes and the pattern of congenital anomalies in pediatric patients with VACTERL association, with a specific focus on the presence of idiopathic syrinxes in this population.
Methods: An institutional database was retrospectively queried for all pediatric patients with VACTERL association.

Objective: Endovascular treatment (EVT) is an effective treatment for patients with acute vertebrobasilar artery complex occlusion (VBAO). However, the benefit of bridging thrombolysis prior to EVT remains controversial. The purpose of the present study is to explore the best treatment strategy between bridging treatment (BT) and direct EVT in patients with acute VBAO.

J Neurosurg Spine
January 2025
15Department of Neurological Surgery, University of California, San Francisco, California.
Objective: The goal of this study was to compare the impact of using a lower thoracic (LT) versus upper lumbar (UL) level as the upper instrumented vertebra (UIV) on clinical and radiographic outcomes following minimally invasive surgery for adult spinal deformity.
Methods: A multicenter retrospective study design was used. Inclusion criteria were age ≥ 18 years, and one of the following: coronal Cobb angle > 20°, sagittal vertical axis > 50 mm, pelvic tilt > 20°, pelvic incidence-lumbar lordosis mismatch > 10°.
