BACKGROUND: Hypotension is one of the most common complications of spinal anesthesia in parturients undergoing cesarean section. In this regard, the patient's position may affect the incidence of hypotension. OBJECTIVES: In this clinical trial, we evaluated the effects of 1- and 2-minute sitting positions versus immediately lying down after spinal anesthesia on hypotension and vasopressor requirements. METHODS: A total of 72 parturients, scheduled for cesarean section under spinal anesthesia, were randomly divided into 3 groups (24 subjects per group)...

A finite element model was developed to investigate the effect of loading regimes caused by various daily activities on the mechanical behaviour of the head-neck taper junction in modular hip replacements. The activities included stair up, stair down, sit to stand, stand to sit, one leg standing and knee bending. To present the real mechanical environment of the junction, in addition to the force components, the frictional moments produced by the frictional sliding of the head and cup were applied to a CoCr/CoCr junction having a 12/14 taper with a proximal mismatch angle of 0...

Wearable sensors such as Inertial Measuring Units (IMUs) have been widely used to measure the quantity of physical activities during daily living in healthy and people with movement disorders through activity classification. These sensors have the potential to provide valuable information to evaluate the quality of the movement during activities of daily living (ADL) such as walking, sitting down and standing up, which could help clinicians to monitor rehabilitation and pharmaceutical interventions. However, high accuracy in the detection and segmentation of these activities is necessary for proper evaluation of the quality of the performance within a given segment...

Patients with impaired walking function are often dependent on assistive devices to retrain gait and regain independence in life. To provide adequate support, gait rehabilitation devices have to be manually set to the correct support mode or have to recognize the type and starting point of a certain motion automatically. For automated motion type detection, machine learning-based classification algorithms using sensor signals from different body parts can achieve robust performance. However, until today, there is only little work available to detect motion onset...

Infants' emotional reactions to an unusual event were assessed at a simulated birthday party during which two costumed characters enacted a Teddy Bear's Picnic. Two hundred and fifty-eight firstborn infants in a representative British community sample were observed at a mean age of 12.8 months in the presence of their parents and other participating families, in a laboratory sitting room decorated with balloons and banners. The picnic scenario was followed by free play with the other participating infants...

Transradial coronary angiography has significantly increased in the United States over the last decade. When the patient is unable to lie down despite analgesia and conscious sedation, general anesthesia may be recommended. We report the feasibility of transradial coronary angiogram in a sitting position.

BACKGROUND: Stereotactic transcerebellar biopsies of brainstem tumors have often been reported. The Leksell frame or Cosman-Roberts-Wells frame is often used in transcerebellar approaches. However, to access lesions via the cerebellum, these frames should be secured as inferiorly on the cranium as possible, which can require exaggerated neck flexion and limit the flexible trajectory to the target. To overcome these disadvantages, we have devised a new way to use the Leksell frame for transcerebellar approaches...

PURPOSE: A multidimensional classification approach suggests that motor control impairment subgroups exist in non-specific chronic low back pain (NSCLBP). Differences in sitting lumbar posture have been identified between two such subgroups [flexion pattern (FP) and active extension pattern (AEP)] and healthy individuals; however, functional spinal movement has not been explored. This study will evaluate whether NSCLBP subgroups exhibit regional spinal kinematic differences, compared to healthy individuals, during functional tasks...

REVIEW
Thomas P Brown
Pure autonomic failure is a degenerative disorder of the peripheral autonomic nervous system. Patients experience symptomatic hypotension that requires them to sit, squat or lie down to prevent syncope. It is associated with characteristic histopathological findings, resulting in neuronal cytoplasmic inclusions in the peripheral autonomic nerves. These lesions are responsible for defects in the synthesis and release of norepinephrine from sympathetic nerve terminals, resulting in significant hypotension. Patients with autonomic failure also have exaggerated blood pressure responses to common stimuli such as food or fluid intake, heat, exercise and medications...

Hiroaki Ichijo
Although several researchers have tried various canalith repositioning procedures for lateral canalolithiasis, a standard treatment has not been established. We adopt 120° rotation, which is anatomically appropriate because the principle of cure may be the fixing of pathological debris to the dark cells of the utricle. The aims of this study were to clarify the efficacy rate of the affected-ear-up 120° maneuver and to elucidate the appearance rate of lying-down nystagmus in patients with lateral canalolithiasis...

Loss of hydrostatic pressures in microgravity may alter skin and bone microvascular flows in the lower extremities and may potentially reduce wound healing and bone fracture repair. The purpose of this study was to determine the rate at which skin and bone microvascular flows respond to head down tilt (HDT). We hypothesized that microvascular flows in tibial bone and overlying skin would increase at different rates during HDT. Tibial bone and skin microvascular flows were measured simultaneously using photoplethysmography (PPG) in a total of 17 subjects during sitting (control posture), supine, 6° HDT, 15° HDT, and 30° HDT postures in random order...

RNAi based sterile insect technique (SIT) is an authentic insect management approach but requires proper target genes. During this study, spermless males were developed by interfering with germ cell differentiation and azoospermia related genes. Data demonstrates significant reductions in the target genes expressions (boul, zpg, dsx (M) , fzo and gas8) after oral dsRNAs administration. Knock down of target genes significantly affected the reproductive ability of males and reduced egg-hatching as compared to the control group...

A high variability in functional tests and activities used during the pulmonary rehabilitation has been observed in post-intensive care unit (ICU) patients, and the best battery of tests to adopt has not been described yet. We tested in patients admitted in a post-ICU Step Down Unit the ability to perform the more frequent functional volitional tests. The relations of each single volitional test with general disability and dyspnea at discharge were also evaluated. Ten volitional tests including: bedside spirometry test (ST: FEV1%, FVC%), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Peak Expiratory Flow during Cough (PCEF), Quadriceps Muscle Strength (QMS), latissimus Dorsi and teres Major Strength (DMS), Brachial biceps Muscle Strength (BMS), effort tolerance measured by sit-to-stand test, Takahashi test and 6-Min Walking Test (6MWT), were evaluated in post-ICU patients at entry and discharge from in-hospital rehabilitation...

Allergen-specific immunotherapy (allergen-SIT) is a highly effective treatment for children with allergic asthma (AA), an immune-mediated chronic disease leading to bronchial muscle hypertrophy and airway obstruction in response to specific allergens. T helper cells and secreted cytokines play important roles in the pathogenesis of asthma, and epigenetic modulation controls genes important for T cell development and cytokine expression. This study evaluated T helper cell-secreted cytokines and DNA methylation patterns in children treated with Dermatophagoides pteronyssinus (Der p) allergen-SIT...

BACKGROUND: Functional neuromuscular stimulation, lower limb orthosis, powered lower limb exoskeleton, and hybrid neuroprosthesis (HNP) technologies can restore stepping in individuals with paraplegia due to spinal cord injury (SCI). However, a self-contained muscle-driven controllable exoskeleton approach based on an implanted neural stimulator to restore walking has not been previously demonstrated, which could potentially result in system use outside the laboratory and viable for long term use or clinical testing...
