Energy spectral density as valid parameter to compare postural control between subjects with nonspecific chronic low back pain vs healthy subjects : …

2021

Abstract Background Nonspecific chronic low back pain (NSCLBP) is one of the most common and frequent health problems. Objetive to compare postural control (i.e. center of pressure (CoP) displacement and energy spectral density (ESD)) using technological devices (accelerometers and pressure platform) between subjects with NSCLBP and healthy subjects. Methods A cross-sectional case-control study was conducted. Observational study (STROBE). The final sample consisted of 60 subjects (30 NSCLBP subjects and 30 healthy subjects). Triaxial accelerometer and pressure platform were used in order to obtain ESD and CoP displacement measurements during four balance tasks (i.e. with and without vision …

Pulmonary Hypertension and Thromboembolic Disease

2008

Pulmonary hypertension (PH) is a disease group that includes a wide variety of entities leading to an increased pulmonary arterial pressure. This chapter describes the basic mechanisms that lead to PH and the possibilities of MRI in diagnosing different aspects. A MR imaging protocol is provided making MRI a comprehensive modality for the classification of the underlying disease and assessment of hemodynamics.

Precapillary Servo Control of Blood Pressure and Postcapillary Adjustment of Flow to Tissue Metabolic Status

1996

Background There are several shortcomings in current understanding of how the microvasculature maintains tissue homeostasis. Presently unresolved issues include (1) integration of the potentially conflicting needs for capillary perfusion and hydrostatic pressure regulation, (2) an understanding of signal transmission pathways for conveying information about tissue energetic status from undersupplied tissue sites to the arterioles, (3) accounting for the experimentally observed interrelations between precapillary and postcapillary resistances, and (4) an explanation of how precise local adjustment of perfusion to metabolic demands is achieved. Methods and Results A novel conceptualization o…

SAT0136 Focus on Implementation of Cardiovascular Risk Factor Recording for Patients with Rheumatoid Arthritis in A Rheumatology Outpatient Clinic

2014

Objectives There is a need for implementing the knowledge of cardiovascular (CV) risk in patients with rheumatoid arthritis (RA) into clinical practice. Our aim was to evaluate CV risk factor (CVRF) recording in a rheumatology outpatient clinic (ROC), where the standard was annual CVRF recording. A second aim was to compare CVRF recording between a regular ROC (RegROC) and an arthritis clinic (AC), which consisted of a structured, team-based model. Methods In 2012, 1142 RA patients visited the ROC of the Hospital of Southern Norway. Of these 612 attended RegROC and 530 attended AC. We conducted a search in the patients9 hospital records to identify recording of CVRFs. Results CVRFs were rec…

Cardiovascular consequences of sleep disordered breathing: the role of CPAP treatment

2020

CPAP treatment decreases BP in OSA patients, especially in severe OSA, and in patients with poorly controlled BP. OSA adversely affects heart function and remodelling, but its role in the pathogenesis of HF remains unclear. Similarly, the impact of CPAP is uncertain, and results of the ongoing ADVENT-HF trial will provide more information. Several experimental studies in animals and humans indicate a central role of intermittent hypoxia in atherogenesis through multiple mechanisms. However, randomised controlled trials (RCTs) in patients with CAD and OSA found no difference in outcomes between CPAP-treated and untreated patients. The negative results of secondary prevention RCTs may be the …

“Small Volume Resuscitation” as Treatment of Cerebral Blood Flow Disturbances and Increased ICP in Trauma and Ischemia

1996

“Small volume resuscitation” (SVR) is a promising concept for the treatment of shock and trauma patients. SVR utilizes the fast infusion of a small volume of hypertonic saline to mobilize intraendothelial and parenchymal water to expand and restitute intravascular volume. Therefore it seems warranted to also consider SVR for the treatment of disturbances of the cerebral circulation and of increased intracranial pressure (ICP). The current study uses a rabbit model of global cerebral ischemia combined with mild hemorrhage to test SVR. Somatosensory evoked potentials (SEPs) serve as a short-term outcome parameter. The data demonstrate a beneficial effect on ICP, a better reperfusion, and an i…

Pulmonale Thrombendarteriektomie bei thromboembolischer pulmonaler Hypertonie: Indikationen und Frühergebnisse

2008

Pulmonary thrombendarterectomy was performed in 32 patients (14 men and 18 women; mean age 38 +/- 15 years) with thromboembolic pulmonary hypertension (New York Heart Association stage III: n = 22; stage IV: n = 10). The preoperative arterial pO2 averaged 59 +/- 11 mm Hg; pulmonary vascular resistance (PVR) and mean pressure (MPAP) were increased to 1,045 +/- 430 dyn.s.cm-5 and 53 +/- 12 mm Hg, respectively. The perioperative death rate was 22% (7 of 32). In the 25 survivors the pulmonary hypertension was reduced to a PVR of 194 +/- 75 dys.s.cm-5, MPAP of 28 +/- 6 mm Hg. Subsequent re-examination in 15 patients (NYHA stage I: n = 14, stage II: n = 1) after a mean of 17 +/- 5 months demonstr…
