Preoperative identification of the eloquent brain is important for neurosurgical planning. One common method of finding the motor cortex is by localizing "the Omega sign." No studies have tested the reliability of imaging to identify the Omega sign. We identified 40 recent and consecutive patients who had undergone preoperative functional magnetic resonance imaging for identification of the hand motor area prior to tumor resection. We recruited 11 neurosurgical residents of various levels of training and one board-certified neurosurgeon to identify the hand motor cortex Omega...

The cyber domain of military operations presents many challenges. A unique element is the social dynamic between cyber operators and their leadership because of the novel subject matter expertise involved in conducting technical cyber tasks, so there will be situations where senior leaders might have much less domain knowledge or no experience at all relative to the warfighters who report to them. Nonetheless, it will be important for junior cyber operators to convey convincing information relevant to a mission in order to persuade or influence a leader to make informed decisions...

BACKGROUND: Ultrasonography is recognised as an invaluable imaging modality for assessing critically unwell patients and obtaining vascular access. Senior emergency medicine and anaesthetic clinicians will regularly use ultrasound-guided imaging to establish vascular access for unwell patients; however, junior doctors, who are routinely the first clinicians to review deteriorating patients, are not encouraged or required to develop basic ultrasound interventional skills and are therefore ill equipped to use ultrasonography...

Child maltreatment is a leading cause of childhood morbidity in the United States, often leading to lifelong adverse health consequences. Currently, there is a nationwide shortage of child abuse pediatricians (CAPs), resulting in many unfilled child abuse positions throughout the United States. In addition, the number of future CAPs currently in fellowship training will meet neither the current need for CAPs nor provide replacements for the senior CAPs who will be retiring in the next 5 to 10 years. Although it is recognized that pediatric nurse practitioners (PNPs) play an important role in the care of maltreated children, there are few available data on the impact of the PNP as an integral member of the child abuse team...

BACKGROUND: A large proportion of age-related fecal incontinence is attributed to weakness or degeneration of the muscles composing the anal continence organ. However, the individual role of these muscles and their functional interplay remain poorly understood. METHODS: This study employs a novel technique based on the combination of MR imaging and FLIP measurements (MR-FLIP) to obtain anatomical and mechanical information simultaneously. Unlike previous methods used to assess the mechanics of the continence organ, MR-FLIP allows inter-individual comparisons and statistical analysis of the sphincter morpho-mechanical parameters...

PURPOSE OF THE STUDY: Hypofunctioning breasts are typically considered a dysfunction of higher brain centers that regulate hormonal feedback, and olfactory information has been proposed as a triggering factor for lactation in the maternal body. However, there are no substantive studies regarding whether olfaction disorders and/or loss of olfactory sense may result in breast gland atrophy by causing diminished olfactory stimulation. To fill this gap in the literature, we studied the histologic features of breast glands as a sample model in animals that had undergone an olfactory bulb lesion (OBL)...
