In this study, we propose functional near infrared spectroscopy (fNIRS) to objectively grade different levels of mental stress. The levels of stress were set based on the difficulty of arithmetic task, time pressure and negative feedback about peer performance. We examined the proposed approach on twelve human subjects using the Montreal Imaging Stress Task. The experiment results revealed a reduction in cortical activation at prefrontal cortex when stressed, and the differences in hemodynamic response between control condition and under stress were significant for arithmetic difficulty level one, two and three, respectively, (p = 0...

Computational Fluid Dynamics enables the investigation of patient-specific hemodynamics for rupture predictions and treatment support of intracranial aneurysms. However, due to numerous simplifications to decrease the computations effort, clinical applicability is limited until now. To overcome this situation a clinical research software prototype was tested that can be easily operated by attending physicians. In order to evaluate the accuracy of this prototype, four patient-specific intracranial aneurysms were investigated using four different spatial resolutions...

This report examines the potential of low level laser therapy (LLLT) to alter brain cell function and neurometabolic pathways using red or near infrared (NIR) wavelengths transcranially for the prevention and treatment of cognitive impairment. Although laser therapy on human tissue has been used for a number of medical conditions since the late 1960s, it is only recently that several clinical studies have shown its value in raising neurometabolic energy levels that can improve cerebral hemodynamics and cognitive abilities in humans...

Due to a shortage of donor hearts, rotary left ventricular assist devices (LVADs) are used to provide mechanical circulatory support. To address the preload insensitivity of the constant speed controller (CSC) used in conventional LVADs, we developed a preload-based Starling-like controller (SLC). The SLC emulates the Starling law of the heart to maintain mean pump flow ([Formula: see text]) with respect to mean left ventricular end diastolic pressure (PLVEDm) as the feedback signal. The SLC and CSC were compared using a mock circulation loop to assess their capacity to increase cardiac output during mild exercise while avoiding ventricular suction (marked by a negative PLVEDm) and maintaining circulatory stability during blood loss and severe reductions in left ventricular contractility (LVC)...

Massive pulmonary embolism (PE) refers to large emboli that cause hemodynamic instability, right ventricular failure, and circulatory collapse. According to the 2016 ACCP Antithrombotic Guidelines, therapy for massive PE should include systemic thrombolytic therapy in conjunction with anticoagulation and supportive care. However, in patients with a contraindication to systemic thrombolytics or in those who fail the above interventions, extracorporeal membrane oxygenation (ECMO) and/or surgical embolectomy may be used to improve oxygenation, achieve hemodynamic stability, and successfully treat massive PE...

BACKGROUND: Transversus abdominis plane (TAP) block provides effective postoperative analgesia after abdominal surgeries. It can be also a useful strategy to reduce perioperative opioid consumption, support intraoperative hemodynamic stability and promote early recovery from anesthesia. The aim of this prospective randomized double-blind study was to assess the effect of subcostal TAP blocks on perioperative opioid consumption, hemodynamic and recovery time in living liver donors. METODS: The prospective, double-blinded, randomized controlled study was conducted with 49 living liver donors, aged 18-65 years, who were scheduled to undergo right hepatectomy...

We report the case of a 79-year-old woman who presented to our hospital for elective removal of an infratentorial meningioma and suffered a periprocedural cardiac arrest. Shortly after uncomplicated induction of anesthesia prior to the surgery, the patient became hypotensive and bradycardic, culminating ultimately in a cardiac arrest with pulseless electrical activity. Return of spontaneous circulation occurred within 90 seconds of arrest, but the patient remained dependent on maximal doses of epinephrine and dopamine for hemodynamic support...

REVIEW
Rashmi Ramachandran, Vimi Rewari
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, (123)I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging...

BACKGROUND: Effects of increased adenosine dose in the assessment of fractional flow reserve (FFR) were studied in relation to FFR results, hemodynamic effects and patient discomfort. FFR require maximal hyperemia mediated by adenosine. Standard dose is 140 μg/kg/min administrated intravenously. Higher doses are commonly used in clinical practice, but an extensive comparison between standard intravenous dose and a high dose (220 μg/kg/min) has previously not been performed. METHODS: Seventy-five patients undergoing FFR received standard dose adenosine, followed by high dose adenosine...

Pregnancy is typically contraindicated in Eisenmenger syndrome because of its association with excessively high maternal and fetal morbidity and mortality. We report on our novel approach to successfully managing a 29 year-old pregnant woman with an unrepaired patent ductus arteriosus (PDA) with Eisenmenger syndrome through delivery and recovery. Venovenous ECMO was utilized during induction of labor to stabilize maternal hemodynamics and optimize fetal oxygenation by creating an oxygenated right-to-left shunt through the PDA...

INTRODUCTION: Liver injuries remain major obstacle for successful treatment, due to size and location of the liver. Requirement for surgery should be determined by clinical factors, most notably hemodynamical state. In this present study we tried to declare our approach to liver traumas. We also tried to emphasize the importance of conservative treatment, since surgeries for liver traumas carry high mortality rates.

Brain oscillations and synchronicity among brain regions (brain connectivity) have been studied in resting-state (RS) and task-induced settings. RS-connectivity which captures brain functional integration during an unconstrained state is shown to vary with the frequency of oscillations. Indeed, high temporal resolution modalities have demonstrated both between and cross-frequency connectivity spanning across frequency bands such as theta and gamma. Despite high spatial resolution, functional magnetic resonance imaging (fMRI) suffers from low temporal resolution due to modulation with slow-varying hemodynamic response function (HRF) and also relatively low sampling rate...

BACKGROUND: In addition to severe hypoxia and hypercapnia, acute respiratory distress syndrome (ARDS) can present with substantial hemodynamic compromise, requiring inotropic or vasopressor support or both. Either venovenous (VV) or venoarterial (VA) extracorporeal membrane oxygenation (ECMO) can be offered in this situation. However, a contemporary comparison of these two cannulation strategies has yet to be well described. METHODS: The Extracorporeal Life Support Organization Registry was reviewed for all cases of adult ARDS in patients that required inotropic agents or vasopressors or both before ECMO initiation (2009 to 2013)...

This critically appraised topic (CAT) study aims to evaluate the quality and extent of the scientific evidence that supports the use of focused assessment with sonography for trauma (FAST) versus multidetector computed tomography (MDCT) in hemodynamically stable trauma patients in the emergency room. An efficient search of the literature yielded several recent articles with a high level of evidence. The CAT study concludes that FAST is an acceptable initial imaging test in hemodynamically stable patients, although its performance is limited in certain circumstances...
