OBJECTIVE The objective of this narrative review is to discuss the potential for burnout in chiropractic practitioners. This discussion is grounded in the job demands-resource model, the conservation of resources model, the unique profession-specific stressors experienced by chiropractors, and information from similar health care professions. METHODS A search using both the indexed (PubMed an...

BACKGROUND Percutaneous vertebroplasty by injecting PMMA bone cement into the fractured vertebrae has been widely accepted in treatment of spinal compression fracture. However, the exothermic polymerization of bone cement may cause osseous or neural tissue injury. This study is thus designed to evaluate the potential risk of thermal damage in percutaneous vertebroplasty. METHOD Twelve porcine...

In this letter, we aim to measure the relative contribution of coincidence detection and temporal integration to the firing of spikes of a simple neuron model. To this end, we develop a method to infer the degree of synchrony in an ensemble of neurons whose firing drives a single postsynaptic cell. This is accomplished by studying the effects of synchronous inputs on the membrane potential slop...

Mortality is markedly elevated in patients with end-stage renal disease. The leading cause of death is cardiovascular disease. Lipoprotein levels are only slightly elevated in dialysis patients, and cardiovascular risk is inversely correlated with serum cholesterol, suggesting that a process other than hyperlipidemia plays a role in the incidence of cardiovascular disease. Hypoalbuminemia, ascr...

Perhaps the single biggest distortion to the free enterprise system is when a number of private institutions are deemed by political and regulatory authorities as too systemic to fail. Resources are trapped in corporate structures that have repeatedly proven their incompetence, and further resources are sucked in from the taxpayer as these institutions destroy value. Indeed, these institutions ...

BACKGROUND Intramural leiomyomas have been long debated as a potential cause of infertility and pregnancy loss. FINDINGS Previous research has linked intramural fibroids to defective implantation, as well as to abnormal peristaltic events of the uterine smooth muscle. Previous reports describe the effects of intramural fibroids on normal human fertility and early pregnancy loss, specifically ...

The exponential growth of data demands scalable and adaptable infrastructures for indexing and searching a huge amount of data sources with high accuracy and efficiency. Existing centralized search engines are not scalable and suffer from single-point-offailures. The recent work on P2P index construction partitions the document vectors either randomly or statically, making it difficult to trade...

The traditional approach of reliability prediction using software reliability growth models requires a large number offailures which might not be available at the beginning of the testing. The commonly used maximum likelihood estimates may not even exist or converge to a reasonable value. In this paper, an approach of making use of information ji-om similar projects in order to obtain an early ...

Background: The extensive education on contraceptive methods, particularly in rural areas of developing countries, play a pivotal role in preventing of induced abortion. The main purpose of this study was to determine the prevalence and major cause of induced abortion in women in northwestern Iran. Materials and Methods: The hospital documentary of 848 women encountering medical examinations du...
