INTRODUCTION: Individuals with over- or under-covered hips may develop hip osteoarthritis. Femoral head coverage is typically evaluated using radiographs, and/or computed tomography (CT) or magnetic resonance images obtained supine. Yet, these static assessments of coverage may not provide accurate information regarding the dynamic, three-dimensional (3-D) relationship between the femoral head and acetabulum. The objectives of this study were to: 1) quantify total and regional 3-D femoral head coverage in a standing position and during gait, and 2) quantify the relationship between 3-D femoral head coverage in standing to that measured during gait...

We aimed to compare the ability of pulse pressure variation (PPV) to predict fluid responsiveness in prone and supine positions and investigate effect of body mass index (BMI), intraabdominal pressure (IAP) and static respiratory compliance (CS) on PPV. A total of 88 patients undergoing neurosurgery were included. After standardized anesthesia induction, patients' PPV, stroke volume index (SVI), CS and IAP values were recorded in supine (T1) and prone (T2) positions and after fluid loading (T3). Also, PPV change percentage (PPVΔ% ) between T2 and T1 times was calculated...

BACKGROUND: The optimal position for surgery is one in which the patient is provided the best possible surgical intervention and put at minimum risk. Different surgical positions may cause changes in tissue perfusion. This study investigates the relationship between surgical patient positions and perfusion index. METHODS: A sample of 61 healthy individuals with no peripheral circulatory disorders, chronic diseases, or anemia was included in this study. Participants held six different positions: supine, prone, 45-degree sitting-supine, 45-degree supine with legs lifted, Trendelenburg (45-degrees head down), and reverse Trendelenburg (45-degrees head up)...

BACKGROUND: Assessing diaphragm mobility is important to detect malfunctions or impending exhaustion and to evaluate the effects of many chest and abdominal conditions on respiratory mechanics. Amongst several imaging methods, ultrasonography represents the only noninvasive, nonionizing imaging technique widely available for the direct assessment of diaphragm excursion. OBJECTIVES: the aim of this study is to prospectively assess the supine diaphragmatic motion amplitude, intra- and inter-observer agreement, and anthropometric correlates of diaphragm motion variability, measured through M-mode ultrasonography, in a sample of healthy volunteers...

This video demonstrates bilateral posterior communicating artery (PCoA) aneurysms that were treated through a unilateral supraorbital approach. A 53-year-old woman presented with a Hunt-Hess grade I subarachnoid hemorrhage (SAH). Computed tomography scan showed SAH in the left sylvian fissure and basal cistern. Angiography demonstrated bilateral aneurysms of the PCoA. Considering posteromedial projection of the contralateral aneurysm, unilateral approach from the side of the ruptured aneurysm was chosen to clip bilateral aneurysms...

NEW FINDINGS: What is the central question of this study? We aimed to examine leg vascular responses to brief periods of inactivity. What is the main finding and its importance? We demonstrate that a mere 10 min of sitting is sufficient to impair leg microvascular function (reactive hyperaemia). However, conduit artery vasodilatation (flow-mediated dilatation) was unaffected, indicating maintained macrovascular function. Interestingly, immobile supine rest also resulted in a reduction in microvascular function alone that was prevented when calf muscle contractions were performed...

Assumed lighting direction in cast-shadow interpretation was investigated. Experiment 1 used an ambiguous object-shadow-matching task to measure bias in shadow-matching direction. The shadow-matching bias was largest when the lighting direction was on average 38.3° left from above (a median of 25.1°). Experiment 2 tested the effect of body posture (head orientation) on cast-shadow interpretation using stimuli aligned in a head-centrically vertical or horizontal orientation. The below-shadow (light-from-above) bias in the head-centric frame was robust across the sitting upright, reclining-on-the-left-side, reclining-on-the-right-side, and supine conditions...

OBJECTIVE: Paralysis resulting from spinal cord injury (SCI) can have a devastating effect on multiple arm and hand motor functions. Rotary hand movements, such as supination and pronation, are commonly impaired by upper extremity paralysis, and are essential for many activities of daily living. In this proof-of-concept study, we utilize a neural bypass system (NBS) to decode motor intention from motor cortex to control combinatorial rotary hand movements elicited through stimulation of the arm muscles, effectively bypassing the SCI of the study participant...
