Real-Time PPG-Based Biometric Identification: Advancing Security with 2D Gram Matrices and Deep Learning Models.

The integration of liveness detection into biometric systems is crucial for countering spoofing attacks and enhancing security. This study investigates the efficacy of photoplethysmography (PPG) signals, which offer distinct advantages over traditional biometric techniques. PPG signals are non-invasive, inherently contain liveness information that is highly resistant to spoofing, and are cost-efficient, making them a superior alternative for biometric authentication.

Severe intensive care unit-acquired hypernatraemia: Prevalence, risk factors, trajectory, management, and outcome.

Background: Severe intensive care unit-acquired hypernatraemia (ICU-AH) is a serious complication of critical illness. However, there is no detailed information on how this condition develops.

Objectives: The objective of this study was to study the prevalence, risk factors, trajectory, management, and outcome of severe ICU-AH (≥155 mmol·L).

ICU-acquired hypernatremia: Prevalence, patient characteristics, trajectory, risk factors, and outcomes.

Objective: Knowledge of intensive care unit (ICU) acquired hypernatremia (ICU-AH) has been hampered by the absence of granular data and confounded by variable definitions and inclusion criteria.

Design: Multicentre retrospective cohort study.

Setting: Twelve ICUs in Queensland (QLD), Australia.

The influence of gender in open surgery and endovascular repair in the treatment of non-ruptured aortoiliac aneurysms.

Objective: This study aimed to determine the outcomes of survival, endoleaks, reinterventions, and perioperative mortality rate (PMR) in patients with AAIA receiving endovascular or open surgical repair with respect to sex, with two groups of patients being evaluated: male and female.

Methods: This was a prospective, single-centered, consecutive cohort study of patients with AAIA who underwent endovascular treatment or open surgical repair regarding gender. Two groups of patients were evaluated: the male group and the female group.

Early Detection of Compartment Syndrome With Minimal Symptoms: A Case Report on Continuous Pressure Monitoring.

Compartment syndrome (CS) arises from various etiologies but is most commonly associated with severe traumatic injuries. It is a difficult diagnosis to make in a timely fashion because clinical signs and symptoms are subjective. Missing the diagnosis is a devastating mistake for the patient and the physician.
