Pulse wave analysis in normal pregnancy: a prospective longitudinal study. [PDF]

, 2009
Outside pregnancy, arterial pulse wave analysis provides valuable information in hypertension and vascular disease. Studies in pregnancy using this technique show that vascular stiffness is raised in women with established pre-eclampsia.

Facial Cosmetic Therapy Use Among Patients With Systemic Sclerosis: An Australian Cohort Study

Arthritis Care &Research, EarlyView.
Objective Systemic sclerosis (SSc) is associated with numerous facial manifestations for which patients may engage in cosmetic therapies. It is unclear how patients with SSc use these therapies. This study sought to characterize patient engagement and experiences with cosmetic therapies for SSc‐related and non‐SSc–related facial changes.

Microvascular Damage Is Associated With Carotid Wall Structural Changes in Systemic Sclerosis: A Capillaroscopy and Ultrasound‐Based Observational Study

Arthritis Care &Research, EarlyView.
Objective Systemic sclerosis (SSc) is characterized by cardiovascular risk excess not fully explained by traditional factors. Whether the severity of microvascular damage correlates with structural subclinical atherosclerosis remains unclear. We investigated the relationship between nailfold videocapillaroscopy (NVC) abnormalities and carotid ...

The effect of positive end-expiratory pressure on pulse pressure variation

Southern African Journal of Anaesthesia and Analgesia, 2012
Objectives: To determine the effect of different levels of positive end-expiratory pressure (PEEP) on pulse pressure variation (PPV).Design: An observational study. Setting: Operating theatres of a tertiary training hospital.Subjects: Ventilated patients who required intra-arterial blood pressure monitoring.Outcome measures: PPV during different levels

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Pulse pressure variation: beyond the fluid management of patients with shock [PDF]

Critical Care, 2007
In anesthetized patients without cardiac arrhythmia the arterial pulse pressure variation (PPV) induced by mechanical ventilation has been shown the most accurate predictor of fluid responsiveness. In this respect, PPV has so far been used mainly in the decision-making process regarding volume expansion in patients with shock.

Assessment fluid responsiveness in septic shock patients: a comparison of automated pulse pressure variation and manually calculated pulse pressure variation [PDF]

Critical Care, 2012
La variación de la presión del pulso (VPP) es un predictor preciso de la capacidad de respuesta de los líquidos en pacientes con ventilación mecánica. El objetivo de este estudio fue la evaluación y comparación de la capacidad del VPP automatizado, cuando se mide mediante un monitor IntelliVue MP 70, y el VPP calculado manualmente para predecir la ...

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

Advanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Evaluation of systolic pressure variation and pulse pressure variation in an experimental model of acute normovolemic hemodilution [PDF]

Critical Care, 2008
Dynamic indicators derived from the arterial pressure waveform analysis as systolic pressure variation (SPV) and pulse pressure variation (PPV) have been shown to be a useful tool to optimize tissue perfusion in clinical and experimental studies. These indicators, however, have not been adequately explored in situations of acute variation of blood ...
