OBJECTIVE: The aim of this study was to test the reliability and validity of the Psychological Conditions Scale (PCS), a measure of drivers of engagement in hospital-based nurses. BACKGROUND: Research suggests drivers of engagement are positive links to patient, employee, and hospital outcomes. Although this scale has been used in other occupations, it has not been tested in nursing. METHODS: A cross-sectional, methodological study using a convenience sample of 200 nurses in a large Magnet® hospital in New Jersey...

Recent clinical data showing thermal lesions from treatments of essential tremor using MR-guided transcranial focused ultrasound shows that in many cases the focus is oblique to the main axis of the phased array. The potential for this obliquity to extend the focus into lateral regions of the brain has led to speculation as to the cause of the oblique focus, and whether it is possible to realign the focus. Numerical simulations were performed on clinical export data to analyze the causes of the oblique focus and determine methods for its correction...

Purpose Ulna-shortening osteotomy is one of the most established and most frequent operations in hand surgery. However, bone union is not always achieved and the use of plates implies potential risks and problems. The traditional points of criticism are the duration of bone healing, the incidence of nonunion, and the necessity of hardware removal due to the soft tissue irritation by the plate or the screws. These shortcomings have been addressed by an increasing standardization of the procedure and finally specific instruments and implants...

OBJECTIVE: Anterior lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion (LLIF) are commonly used approaches for lumbar spine fusion surgery, each with their own unique advantages and disadvantages. ALIF requires mobilization of the great vessels and peritoneum, while dissection of the psoas muscle in the LLIF technique is associated with post-operative neurological complications in the proximal lower limb. The anterior-to-psoas (ATP) or oblique lumbar interbody fusion (OLIF) technique is the proposed solution to accessing the L1-L5 levels without the issues encountered with ALIF and LLIF...

The purpose of this study was to compare the mechanical resistance of three different plates used to treat fractures of the mandibular angle: a regular 4-hole plate, a longer 4-hole plate (both positioned using the Champy technique), and a 3-dimensional plate positioned over the oblique line. Three equal groups of replicas of human dentate mandibles made out of polyurethane resin were used (n=21 in each group). The force was applied perpendicular to the occlusal plane at a rate of 2mm/minute at three different points: the first molar on the sectioned side; the first molar on the contralateral side; and between the central incisors...

This study sought to determine the effects of chronic low back pain (LBP) on the cortical evoked potentials, muscle activation, and kinematics of postural responses to perturbations of standing balance. Thirteen subjects with chronic, recurrent, non-specific LBP and 13 subjects without LBP participated. The subjects responded to unpredictably timed postural perturbations while standing on a platform that randomly rotated either "toes up" or "toes down". Electroencephalography (EEG) was used to calculate the negative peak (N1) and subsequent positive peak (P2) amplitudes of the perturbation evoked cortical potentials...

BACKGROUND: The creation of a superior palpebral crease has been the most popular plastic surgery procedure in Asians for several decades. The most important criterion for judging the success of this procedure is the achievement of the desired size and shape of this crease or the perfect crease width. However, the determinants of crease width remain unclear, which may account for the high rate of unsatisfactory results. METHODS: Standard images were used to study the anatomic parameters, including crease width, crease height, and upper eyelid movement distance (ULMD) at the midpupillary axis, of the inherent double eyelid crease in 32 Chinese women aged 19-26 years...

BACKGROUND: We aimed to evaluate cysts in the lesser tuberosity of humeral head seen on magnetic resonance imaging (MRI) and their relationship with subcoracoid impingement and subscapularis tears evident on arthroscopic surgery videos. Our hypothesis was that the cysts would be more frequent with subscapularis tears and in the case of subcoracoid impingement. METHODS: Patients who underwent shoulder arthroscopy between January 2010 and January 2016 were retrieved to evaluate subscapularis tears on surgery videos and lesser tuberosity cysts (LTC), coracohumeral distances (CHD) on both sagittal oblique and transverse sections of MRI retrospectively...

Electrophysiological recordings from spinal cord slices have proven to be a valuable technique to investigate a wide range of questions, from cellular to network properties. We show how to prepare viable oblique slices of the spinal cord of young mice (P2 - P11). In this preparation, the motoneurons retain their axons coming out from the ventral roots of the spinal cord. Stimulation of these axons elicits back-propagating action potentials invading the motoneuron somas and exciting the motoneuron collaterals within the spinal cord...

: Using the American Society for Bone and Mineral Research Task Force case definition for atypical femoral fractures, sensitivity and specificity of radiographic fracture characteristics were calculated. Fracture pattern was the most sensitive and specific characteristic. This suggests that some characteristics should be weighted more heavily when identifying these fractures. INTRODUCTION: To estimate the sensitivity and specificity of each radiographic criterion in the 2013 ASBMR atypical femoral fracture (AFF) case definition for distinguishing AFF from other subtrochanteric/diaphyseal fractures (non-AFF) among women enrolled in a large integrated health care organization...

Labial striations on the anterior teeth have been documented in numerous European pre-Neandertal and Neandertal fossils and serve as evidence for handedness. OH-65, dated at 1.8 mya, shows a concentration of oblique striations on, especially, the left I(1) and right I(1), I(2) and C(1), which signal that it was right-handed. From these patterns we contend that OH-65 was habitually using the right hand, over the left, in manipulating objects during some kind of oral processing. In living humans right-handedness is generally correlated with brain lateralization, although the strength of the association is questioned by some...

Conventional correction approaches are unsuitable for effectively correcting remote sensing images acquired in the seriously oblique condition which has severe distortions and resolution disparity. Considering that the extraction of control points (CPs) and the parameter estimation of the correction model play important roles in correction accuracy, this paper introduces an effective correction method for large angle (LA) images. Firstly, a new CP extraction algorithm is proposed based on multi-view simulation (MVS) to ensure the effective matching of CP pairs between the reference image and the LA image...

Craniofacial clefts are rare entities, with an incidence reported as 1.43 to 4.85 per 100,000 births. The Tessier number 3 cleft, the most medial of the oblique clefts, can manifest as clefting of the lip between the canine and lateral incisors, colobomas of the nasal ala and lower eyelid, and inferior displacement of the medial canthus-frequently disrupting the lacrimal system with extreme variability in expressivity (Eppley).Literature on cleft lip repair is extensive and has evolved to incorporate anthropometric techniques, based on identifiable landmarks and anthropometric measurements that are compared with contralateral unaffected anatomy or population means and tracked over time to assess impact on growth...

OBJECTIVE: Pitching technique is one of many factors that affect injury risk. Exhibiting excessive contralateral trunk tilt (CLT) during pitching has been linked to higher ball speed but also to increased joint loading. Deficit in trunk muscle strength has been suggested as an underlying cause of this movement pattern. The purpose of the study was to compare trunk muscle strength between youth baseball pitchers with varying degree of CLT during pitching. DESIGN: Cross-sectional study...
