This paper considers some of the changes in practice that have occurred last 5 years. There been significant improvements parental involvement care. Not all based on evidence from research: has also affected by changing technology and pressure industry other groups. Among research-based were: an awareness confidentiality, individualised developmental care, increased use inhaled nitric oxide, therapeutic hypothermia, less postnatal steroids (although dosage used is not evidence-based),...
The use of robots in health care has increased dramatically over the last decade. One area research been to conduct ultrasound examinations, either controlled by a physician or autonomously. This paper examines possibility using commercial robot UR5 from Universal Robots make tele-operated robotic system. Physicians diagnosing patients probes are prone repetitive strain injuries, as they required hold probe uncomfortable positions and exert significant static force. main application for...
Left heart catheterization carries a risk for cerebral complications. The aims of this prospective study were to determine the frequency and composition catheterization-related microemboli detect morphological changes acute cognitive impairment due catheterization.Forty-seven unselected patients undergoing elective left catheterization, either by transradial or transfemoral access, monitored using multifrequency transcranial Doppler. Cerebral magnetic resonance imaging (MRI) with...
Infarct size is a strong predictor of mortality and major adverse cardiovascular events after myocardial infarction. Acute reperfusion therapy limits infarct improves survival, but its use has been confined to patients with ST-segment-elevation The purpose this study was assess the relationship between echocardiographic parameters left ventricular (LV) systolic function obtained before revascularization final in non-ST-segment-elevation infarction, as well ability these identify substantial...
<b><i>Background:</i></b> Extrauterine growth restriction is common among very low birth weight infants (VLBW, BW <1,500 g). Optimal postnatal nutrient supply essential to limit and ensure adequate neurodevelopment. <b><i>Objectives:</i></b> We compared an enhanced a standard evaluated the effects on velocity, head circumference cerebral maturation - latter by magnetic resonance diffusion tensor imaging (DTI). hypothesized increased...
Abstract Executive dysfunction is a common consequence of acquired brain injury (ABI), causing significant disability in daily life. This randomized controlled trial investigated the efficacy Goal Management Training TM (GMT) improving executive functioning patients with chronic ABI. Seventy verified ABI and were randomly allocated to GMT ( n =33) or psycho-educative active control condition, Brain Health Workshop (BHW) =37). In addition, all participants received external cueing by text...
Purpose To test for measurable visual enhancement of the dentate nucleus (DN) on unenhanced T1-weighted magnetic resonance (MR) images in a cohort patients with primary brain tumor who had not received linear gadolinium-based contrast agents (GBCAs) but many injections macrocyclic GBCAs. Materials and Methods Seventeen high-grade gliomas 10–44 administrations GBCA gadobutrol (0.1 mmol/kg body weight) were retrospectively included this regional ethics committee–approved study. Two...
The impact of intraoperative MRI (iMRI) on the surgical procedure, patient outcome and median survival for a series patients harbouring high-grade gliomas forms basis this study. Their has been compared to matched cohort operated in conventional manner determine if use can be shown improve results surgery prognosis type patient.32 microsurgical open craniotomies, performed iMRI scanner grade IV supratentorial gliomas, with follow-up periods more than 2 months, were analyzed A group 32...
Measurement of electrical impedance can discriminate between tissues different properties. A measurement system with adequate spatial resolution focused on a volume around the tip needle or other invasive clinical equipment be used to determine in which type tissue is positioned. We have measured sensitivity zone electrode an active area 0.3 mm(2), and spectra porcine vivo. Small data will influenced by polarization (EPI) at low frequencies. To refine existing methods for guidance higher...
Objectives The neurobiological substrate of bipolar II disorder (BD-II) remains largely unknown. A few previous studies have found evidence for cerebral cortical thinning in mixed samples BD-II and I patients; however, no study thickness or surface area has been limited to BD-II. In the present study, we compared magnetic resonance imaging (MRI)-based indices between individuals with healthy controls. Methods Thirty-six a DSM-IV diagnosis 42 controls underwent 3T MRI. Comparisons relative...
Background There is an unsettled discussion about whether the distribution of local anesthetic free or inhibited when performing brachial plexus blocks. This first study to use magnetic resonance imaging (MRI) help answer this question. Methods Thirteen patients received axillary block by a catheter-nerve stimulator technique. After locating median nerve, total dose 50 ml was injected via catheter in four divided doses 1, 4, 15, and 30 ml. Results sensory motor testing were compared with...
Background: Haemodynamic instability during off‐pump coronary artery bypass surgery (OPCAB) may appear rapidly, and continuous monitoring of the cardiac index (CI) procedure is advisable. With PiCCO monitor, CI can be measured continuously almost real time with pulse‐contour analysis intermittently transthoracic thermodilution. The agreement between pulmonal thermodilution (Tpa), (Tpc) (PCCI) OPCAB has not been evaluated sufficiently. Methods: In 30 patients scheduled for surgery, a...
The discTRODE probe applies radiofrequency (RF) current, heating the annulus to treat chronic discogenic low back pain. Randomized controlled studies have not been published. We assessed long-term effect and safety aspects of percutaneous intradiscal thermocoagulation (PIRFT) with in a prospective parallel, randomized gender stratified, double-blind placebo-controlled study. Twenty selected patients pain positive one-level pressure-controlled provocation discography were either intra-annular...
Objective To test the hypothesis that depressive symptoms correlate with Alzheimer's disease (AD) type changes in CSF and structural functional imaging including hippocampus volume, cortical thickness, white matter lesions, Diffusion tensor (DTI), fluoro-deoxy-glucose positron emission tomography (FDG-PET) patient subjective (SCI) mild (MCI) cognitive impairment. Method In 60 patients, were assessed using Geriatric Depression Scale. The subjects underwent MRI, 18F-FDG PET imaging, lumbar...
During trans-sphenoidal microsurgical resection of pituitary adenomas, the extent may be difficult to assess, especially when extensive suprasellar and parasellar growth has occurred. In this prospective study, we investigated whether intra-operative magnetic resonance imaging (iMRI) can facilitate tumour resection. Twenty patients with macroadenomas, (16 non-functioning, three growth-hormone secreting one pharmaco-resistant prolactinoma) were selected for surgery in iMRI. The mean diameter...
Objectives: Dentate gyrus (DG)‐dependent inhibition of the stress response might play an important role in mood disorders. During stress, hippocampal projections traversing fimbria, a white matter bundle on surface, inhibit hypothalamic–pituitary–adrenal (HPA) axis. The aim present study was to measure volumes DG–cornu ammonis 4 (DG–CA4) and fimbria patients with bipolar II disorder (BD‐II) healthy controls using recently developed magnetic resonance imaging (MRI)‐based technique. Methods:...
