Hemostasis of arteriovenous fistula: Comparison of direct two-finger pressure to an adjustable device.

Background And Objectives: To evaluate the pressure generated by an adjustable hemostasis clamp on arteriovenous fistulas (AVF) during the hemostasis proccess, and compare it with the direct two-finger pressure applied by the patient. To evaluate the variations of the direct two-finger pressure along the hemostasis process.

Methods: We analyzed data obtained in 51 hemodialysis procedures from 15 patients.

Measurement of the anterior chamber depth and ocular axial length: transpalpebral B-mode ultrasound using an 18-MHz linear probe compared with the IOL Master 500.

Aims: To determine the reliability of transpalpebral ultrasound in B-mode (B-TUS) with a high-resolution linear probe (18 MHz) in estimating both the ocular anterior chamber depth (ACD) and axial length (AL), as well as its agreement with the IOL Master 500 optical biometer.

Material And Methods: Cross-sectional study on 82 eyes of 41 volunteers with no history of eye disease. ACD and AL were determined using B-TUS and the IOL Master 500.

Ocular biometry through fully refocused steady-state magnetic resonance imaging sequence: reliability and agreement with the IOLMaster 500.

Purpose: To evaluate the reliability and agreement between Fully Refocused Steady-State magnetic resonance sequences (FRSS) and the IOLMaster 500 optical biometer for measuring anterior chamber depth (ACD) and axial length (AL).

Methods: In a sample of 32 healthy volunteers, separate observers measured the ACD and AL of both eyes using both techniques (inter-method) and through repeated FRSS measurements (interobserver) and by the same observer (intraobserver). We employed the Bland-Altman method to determine the agreement between FRSS and partial coherence interferometry (using the IOLMaster) and the interobserver and intraobserver variability, providing the limits of agreement (LoA, or mean difference ± 1.

Can we improve the early detection of atrial fibrillation in a stroke unit? Detection rate of a monitor with integrated detection software.

Introduction: It is unknown whether monitors that include atrial fibrillation recognition software (AF-RS) increase the rate of early atrial fibrillation (AF) detection in acute stroke. We aimed to evaluate the AF detection rate of an AF-RS monitor and compare it with standard monitoring.

Methods: This was a retrospective, single-centre observational study conducted on consecutive patients with acute transient ischaemic attack or brain infarction attended in a stroke unit (SU) with six beds.

The effect of telestroke systems among neighboring hospitals: more and better? The Madrid Telestroke Project.

A telestroke system was established between a community hospital lacking an on-call neurologist and a comprehensive stroke center only 13 km away. Our goal was to analyze the impact of telestroke on the number of intravenous thrombolysis (IVT), door-to-needle times and stroke outcomes. An observational before-and-after study of patients with acute ischemic stroke (IS) who were attended in a community hospital during the 2 years before the telestroke system was implemented (pre-telestroke group) and the first 2 years after telestroke was established (telestroke group).

[Diagnostic accuracy of an automatic blood pressure device for ankle brachial index determination in ischemic stroke patients].

Introduction: Ankle brachial index (ABI) is not widespread in clinical practice because the need for specific equipment and training. Doing it without these requirements, quicker and with a cheaper method would facilitate their routine use.

Aims: To evaluate sensitivity and specificity of an automatic blood pressure device detecting ABI < 0.

[Enteral feeding set replacement as a key factor in preventing infectious complications].

To know variables facilitating bacterial growth is critical and essential for nursing staff because of high risk of infectious complications associated with enteral nutrition. In this matter the frequency of delivery set changes has a great influence. The analysis of 6 papers showed a high ratio of bacterial growth to unacceptable levels in the sets after the first 24 hours.
