Article Abstract
Non-invasive measurement of intracranial pressure (ICP) using ultrasound has garnered increasing attention. This study aimed to compare the reliability of ultrasonographic measurement of optic nerve sheath diameter (ONSD) and transcranial Doppler (TCD) in detecting potential ICP elevations. Patients who needed lumbar puncture (LP) in the Department of Neurology were recruited from December 2016 to July 2017. The ONSD and TCD measurements were completed before LP. One hundred sixty-five participants (mean age, 41.96 ± 14.64 years; 80 men; 29 patients with elevated ICP) were included in this study. The mean ICP was 170 ± 52 mmHO (range, 75-400 mmHO). Univariate analyses revealed that ICP was non-significantly associated with TCD parameters and significantly associated with ONSD ( = 0.60, < 0.001). The mean ONSD of the elevated ICP group was significantly higher than that of the normal ICP group (4.53 ± 0.40 mm vs. 3.97 ± 0.23 mm; < 0.001). Multivariate linear regression determined that the difference between ICP and ONSD is significant. In the early stage of intracranial hypertension, ONSD is more reliable for evaluating ICP than TCD.

The development of functional materials for osteoporosis is essential for effective bone remodeling. In this context, the extraction of biocompatible implantable biomaterials from bio-waste emerges as a valuable strategy, addressing both environmental challenges and promoting human health. The objective of this work was to evaluate the physicochemical properties of the added-value by-product biomaterial (SS-90), extracted from sardine scales (Sardina Pilchardus) and combined with chitosan (SS-90-CH).

Acute extremity compartment syndrome (CS) is a serious medical complication triggered by factors such as trauma, vascular injury, or prolonged compression, resulting in elevated intracompartmental pressure (ICP) and tissue ischemia. Diagnosis remains challenging, mainly relying on the subjective evaluation of clinical symptoms. Different animal models have been used to study pathophysiology and evaluate diagnostic and therapeutic approaches.

The origin and grade of green tea significantly influence its market value, yet their concurrent authentication remains challenging. Here, we developed a robust method combining multiple metallic elements and back propagation neural network (BPNN) to identify the origin and grade of tea simultaneously. This strategy utilizes inductively coupled plasma atomic emission spectrometry (ICP-AES) to analyze the content of multiple elements in green tea (e.

This study evaluated the feasibility of using ferrous sulfate microparticles (FSM), produced through the combination of spray drying and spray chilling techniques, to fortify plant-based yogurt and increase dietary iron intake. The stability of FSM was assessed, and iron bioavailability was estimated using the standardized INFOGEST in vitro digestion method, followed by Caco-2 cell culture assays. FSM showed moisture content and water activity (Aw <0.

Background: Many traumatic brain injury (TBI) treatment protocols, including the Lund concept, advocate the highest point of the subarachnoid space (typically the vertex) as the zero-reference point for intracranial pressure (ICP) and the level of the right atrium as the zero-reference point for mean arterial blood pressure (MAP). In 2017, at the Department of Neurosurgery in Lund, Sweden, the zero-reference points for ICP and MAP were both changed to the external auditory meatus (EAM), thus altering the calculated cerebral perfusion pressure (CPP) levels. We hypothesized that the ICP and MAP levels obtained from the different zero-reference points resulted in altered neurocritical care management and/or patient outcome.
