Effect of Load Carriage Lifestyle on Kinematics and Kinetics of Gait.

Backpacks are commonly worn by many people for multiple purposes. This study investigated the effects of habitual wearing of backpacks on lower limb kinematics and kinetics. Fourteen participants were recruited for analysis.

Classification of Plank Techniques Using Wearable Sensors.

The plank is a common core-stability exercise. Developing a wearable inertial sensor system for distinguishing between acceptable and aberrant plank techniques and detecting specific deviations from acceptable plank techniques can enhance performance and prevent injury. The purpose of this study was to develop an inertial measurement unit (IMU)-based plank technique quantification system.

The Acute Effect of Foam Rolling and Vibration Foam Rolling on Drop Jump Performance.

The purpose of this study was to examine the acute effect of foam rolling and vibration foam rolling on drop jump performance. The optimal time interval between warm-up using foam rolling or vibration foam rolling and drop jump performance was identified. This study included 16 male NCAA Division I college volleyball athletes.

Early and anticipatory postural adjustments in healthy subjects under stable and unstable sitting conditions.

Clinicians frequently incorporate unstable sitting devices into training plans for improving proximal postural muscle control; however, the effect of unstable sitting conditions on postural adjustments during dynamic activities has not been fully explored. The aim of this study was to characterize early postural adjustments (EPAs) and anticipatory postural adjustments (APAs) under stable and unstable sitting conditions. Using a cross-sectional laboratory study design, 13 healthy college student volunteers used their dominant hand to reach forward and push a target under stable and unstable sitting conditions; subjects sat on an air-filled rubber cushion for the unstable condition.

Dysregulation of endothelial colony-forming cell function by a negative feedback loop of circulating miR-146a and -146b in cardiovascular disease patients.

Functional impairment of endothelial colony-forming cells (ECFCs), a specific cell lineage of endothelial progenitor cells (EPCs) is highly associated with the severity of coronary artery disease (CAD), the most common type of cardiovascular disease (CVD). Emerging evidence show that circulating microRNAs (miRNAs) in CAD patients' body fluid hold a great potential as biomarkers. However, our knowledge of the role of circulating miRNA in regulating the function of ECFCs and the progression of CAD is still in its infancy.

Ogilvie syndrome: a potentially life-threatening phenotype of immobilization hypercalcemia.

Ogilvie syndrome, also known as acute colonic pseudo-obstruction, is characterized by the clinical presentation and imaging evidence of acute colonic obstruction in the absence of a mechanical cause. Several comorbidities and serious associated medical or surgical conditions have been described to be relevant to this syndrome. In general, a preferred initial management with favorable treatment outcomes is virtually to correct underlying disorders.

Incremental validity of person-organization fit over the Big Five personality measures.

Few studies have provided the validity evidence of a measure of objective person-organization fit (P-O fit) as a selection tool. The present study used a concurrent validation design to examine the criterion-related validity and the incremental validity of a P-O fit measure beyond the validity of the Big Five personality test for predicting job performance (task performance and organizational citizenship behavior) and employee commitment (organizational commitment and supervisory commitment) for a group of high-tech professional employees in Taiwan. Results showed that P-O fit predicted the contextual component of overall job performance and was significantly related to two types of employee commitment.

Sentinel central retinal artery occlusion: a forme fruste of idiopathic renal infarction.

Central retinal artery occlusion is one of the most challenging practices and is not an infrequent presentation at the emergency department. We describe a 46-year-old man presenting with abrupt onset of amaurosis fugax secondary to sentinel central retinal artery occlusion followed by acute idiopathic renal infarction. This patient highlights that the preceding visual events could portend a devastating thromboembolic insult in the clinical setting.

Unveiling tuberculous pyomyositis: an emerging role of immune reconstitution inflammatory syndrome.

Immune reconstitution inflammatory syndrome is recognized as a paradoxical worsening of preexisting or smoldering opportunistic infections in patients with human immunodeficiency virus on highly active antiretroviral therapy because of the recuperating of immune system. We report a 42-year-old man on antiretroviral therapy with silent mycobacterium tuberculosis pyomyositis presenting with characteristic clinical and imaging features of immune reconstitution inflammatory syndrome. Because tuberculosis pyomyositis is less recognized and may be easily overlooked in terms of protean manifestations in extrapulmonary tuberculosis spreading, such mycobacterial infection can bring about substantial morbidity and even mortality during the immune recovery phase.

An unusual case of febrile neutropenia: acute myeloid leukemia presenting as myeloid sarcoma of the spleen.

Differential diagnosis of a focal splenic lesion in the context of acute leukemia is quite challenging. A 58-year-old woman presented with a 3-day history of fever and abdominal pain. The results of hematological work-up were consistent with acute myeloblastic leukemia (M2, French-American-British classification).

Acute myeloid leukemia presenting as one-and-a-half syndrome.

One-and-a-half syndrome is a clinical disorder featuring extraocular movements characterized by horizontal conjugate gaze palsy with internuclear ophthalmoplegia. It usually results from a unilateral lesion of the midbrain, and the most common cause of this syndrome in young women is multiple sclerosis. We report the case of a 38-year-old woman diagnosed as having acute myeloblastic leukemia presenting with characteristic neurologic and imaging features of one-and-a-half syndrome.

A life-threatening double gap metabolic acidosis.

Double gap metabolic acidosis represents the high anion gap metabolic acidosis combined with raised serum osmolal gap due to retention of unmeasured osmole with accompanied metabolite. We describe a 62-year-old man diagnosed with community-acquired pneumonia undergoing continuous sedation in the context of asynchronous mechanical ventilation. High anion gap metabolic acidosis coupled with high plasma osmolal gap was noted with resultant severe bradyarrhythmia.

Test of a model linking employee positive moods and task performance.

Past empirical evidence has demonstrated that employees' positive mood states predict task performance. This study extends previous research by proposing and testing a model that examines mediating processes underlying the relationship between employee positive moods and task performance. Two longitudinal studies used data collected from 306 (Study 1) and 263 (Study 2) insurance sales agents in Taiwan.

Mechanisms linking employee affective delivery and customer behavioral intentions.

Past empirical evidence has indicated that employee affective delivery can influence customer reactions (e.g., customer satisfaction, service quality evaluation).
