BACKGROUND In neonatal intensive care unit (NICU), neonatal sleep is disrupted due to different factors. Due to the critical role of sleep in premature infants' brain development, this study aimed to investigate the effect of nesting and swaddling on the sleep duration of premature infants hospitalized in NICUs. MATERIALS AND METHODS In a crossover clinical trial, 42 preterm infants who met t...

BACKGROUND Refining and individualizing treatment of acute pain in the emergency department (ED) is a high priority, given that painful complaints are the most common reasons for ED visits. Few tools exist to objectively measure pain perception in the ED setting. We speculated that variation in perception of fixed painful stimuli would explain individual variation in reported pain and response ...

We generalize an approach to studying the quantum state tomography (QST) of open systems in terms dynamical map Kraus representation within framework dynamic generation informationally complete positive operator-valued measures. As applications, we use generalized theoretically study QST qubit presence nonequilibrium environments which exhibit nonstationary and non-Markovian random telegraph no...

Fitness related traits often show spatial variation across populations of widely distributed species. Comparisons of genetic variation among populations in putatively neutral DNA markers and in phenotypic traits susceptible to selection (QST FST analysis) can be used to determine to what degree differentiation among populations can be attributed to selection or genetic drift. Traditionally, QST...

BACKGROUND Local freezing cold injuries are common in the north and sequelae to cold injury can persist many years. Quantitative sensory testing (QST) can be used to assess neurosensory symptoms but has previously not been used on cold injury patients. OBJECTIVE To evaluate neurosensory sequelae after local freezing cold injury by thermal and vibrotactile perception thresholds and by symptom ...

Pain catastrophizing, a pattern of negative cognitive-emotional responses to actual or anticipated pain, maintains chronic pain and undermines response to treatments. Currently, precisely how pain catastrophizing influences pain processing is not well understood. In experimental settings, pain catastrophizing has been associated with amplified pain processing. This study sought to clarify pain ...

Genetic drift and selection are ubiquitous evolutionary forces acting to shape genetic variation in populations. While their relative importance has been well studied in plants and animals, less is known about their relative importance in fungal pathogens. Because agro-ecosystems are more homogeneous environments than natural ecosystems, stabilizing selection may play a stronger role than genet...

Future physician leaders will need the knowledge and skills necessary to improve systems of care. To address this need, Pritzker School of Medicine implemented a 4-year scholarly track in quality and patient safety for medical students. The Quality and Safety Track (QST) includes an intensive elective that teaches basic quality-improvement skills, an individual mentored scholarly project, and e...

BACKGROUND This study evaluated Somatosensory evoked potentials (SEP), Quantitative sensory testing (QST), and thermography as diagnostic methods for nerve injury. METHODS From 2006 through 2011, 17 patients (mean age: 50.1 years) from OOOO Hospital who sought care for altered sensation after dental implant treatment were identified. The mean time of objective assessment was 15.2 months after...

This review is provided as a service to the membership of the American Association of Electrodiagnostic Medicine (AAEM). This paper discusses quantitative sensory testing (QST) equipment using the following sensory modalities: 1) light touch, 2) vibration, 3) thermal, and 4) pain. First, is a summary of the different QST equipment and the equipments’ specifications as reported in the literature...
