AI Article Synopsis
- The study compares the effectiveness of transcranial color-coded sonography (TCCS) and transcranial Doppler (TCD) in accurately diagnosing elevated intracranial pressure (ICP).
- Both methods were tested on neurocritical care patients with either high or normal ICP, using continuous measurements from an intraparenchymal catheter as the standard reference.
- The results showed no significant differences in PI values between the two methods, with both demonstrating good diagnostic accuracy; however, TCCS required a longer measurement time than TCD.
Article Abstract
Objective: The aim of this study is to prospectively compare the accuracies of transcranial color-coded sonography (TCCS) and transcranial Doppler (TCD) in the diagnosis of elevated intracranial pressure.
Methods: A prospective, blinded, head-to-head comparison of TCD and TCCS methods using intracranial pressure (ICP) measured continuously via an intraparenchymal catheter as the reference standard in 2 groups of 20 neurocritical care patients each: high ICP (group 1) and normal ICP (group 2). Middle cerebral artery (MCA) pulsatility index (PI) recordings from all patients' sonographic reports were selected based on the highest left or right recorded MCA PI. Transcranial Doppler was performed using a dedicated TCD device, and TCCS was performed using a portable ultrasound system.
Results: The PI values obtained did not differ significantly between the 2 methods (group 1, P = .46; group 2, P = .11). Linear regression analysis identified a significant relationship between PI obtained with both methods (r = 0.897; P < .0001). The duration of PI measurement was statistically longer with TCCS than TCD (group 1, P < .01; group 2, P < .01). Diagnostic accuracies were good and similar for both methods (TCD area under curve, 0.901; TCCS area under curve 0.870; P = .69).
Conclusions: This work is a pilot study comparing TCCS and TCD in the detection of elevated ICP. This study suggests that a bedside portable ultrasound system may be useful to determine MCA PI with accuracy similar to that of a dedicated TCD device.

Background: Recent technological advances have introduced novel methods for measuring body composition, each with unique benefits and limitations. The choice of method often depends on the trade-offs between accuracy, cost, participant burden, and the ability to measure specific body composition compartments.
Objective: To review the considerations of cost, accuracy, portability, and participant burden in reference and emerging body composition assessment methods, and to evaluate their clinical applicability.

Background: The viability of the liver pre-transplant depends on the type of donor, age, medical history, circumstances of death, result of analytics, and complementary exploration of the abdominal cavity. Abdominal ultrasound is the initial option for the assessment of previously unknown liver disease, such as the qualitative determination of hepatic steatosis . The presence of hepatic steatosis is considered a risk factor for graft failure after liver transplantation, therefore, at the time of clinical assessment of the donor or its presence in the macroscopic assessment in the operating room can be cause for rejection of the organ by the transplant teams.

Problem: Breast cancer is a leading cause of death among women, and early detection is crucial for improving survival rates. The manual breast cancer diagnosis utilizes more time and is subjective. Also, the previous CAD models mostly depend on manmade visual details that are complex to generalize across ultrasound images utilizing distinct techniques.

Infectious diseases, especially respiratory infections, have been significant threats to human health. Therefore, it is essential to develop rapid, portable, and highly sensitive diagnostic methods for their control. Herein, a short-time preamplified, one-pot clustered regularly interspaced short palindromic repeats (CRISPR) nucleic acid detection method (SPOC) is developed by combining the rapid recombinase polymerase amplification (RPA) with CRISPR-Cas12a to reduce the mutual interference and achieve facile and rapid molecular diagnosis.
