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: Natural killer cells (NK cells) are cytotoxic lymphocytes of innate immunity that reveal some immunoregulatory properties, however, their role in the process of ageing is not completely understood. The study aimed to analyze the expression of proteins involved in cellular stress response: sirtuin 1 (SIRT1), heat shock protein 70 (HSP70) and manganese superoxide dismutase (SOD2) in human NK cells with reference to the process of ageing. Non-stimulated and stimulated with IL-2, LPS or PMA with ionomycin cells originated from peripheral blood samples of: seniors aged over 85 ('the oldest'; n  = 25; 88...

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)...

ISSUE ADDRESSED: Exercising outdoors provide beneficial effect on mental and physical health for all ages. However, few older people exercise outdoors other than walking. While outdoor gyms have become increasingly common in Australia, limited outdoor exercise equipment specifically designed for older people is available in public spaces. We have set up and evaluated a unique purpose-built outdoor exercise park for older people in the community setting, and demonstrated positive physical and well-being outcomes associated with the provision of this unique exercise mode and social program...

In its third year of existence, the French Phage Network ( is pursuing its expansion. With more than 25 groups, mostly based in France, working on the various aspects of phage research, the network has increased its visibility, interactivity, and activity. The third meeting of the network, held on November 2017 at the Gif-sur-Yvette Centre National de la Recherche Scientifique (CNRS) campus, was a great opportunity for many young scientists to present their work and interact with more senior scientists, amongst which several were invited from abroad...

BACKGROUND: Student self-debriefing promotes self-confidence, helps to increase clinical performance, and is a more cost-effective method than is traditional instructor-led debriefing in simulation-based learning. OBJECTIVES: This study compared the effectiveness of debriefing-in terms of the problem-solving process, team effectiveness, debriefing assessment, and debriefing satisfaction-between an experimental group who received both student self-debriefing (SSD) and instructor debriefing (ID) and a control group who received only instructor debriefing...

BACKGROUND: The Enhanced Recovery After Surgery (ERAS) program has been shown to reduce length of stay (LOS) in colorectal surgical patients in randomized trials. The impact outside of trial settings, or in subgroups of patients excluded from trials such as individuals with diabetes, is uncertain. We conducted this study to evaluate the impact of ERAS implementation in Alberta, Canada. METHODS: This is a retrospective cohort study and interrupted time series analysis using linked administrative data to examine LOS and postoperative outcomes in the 12 months pre- and post-implementation of ERAS in 2013 for all adults undergoing elective colorectal surgery...

Poor sleep is common among older adults, often caused by multiple underlying factors such as chronic stress. Poor sleep is subsequently associated with negative health outcomes including higher morbidity and mortality. Our primary purpose is to explore practical non-pharmacological intervention approaches integrating stress management to improve sleep quality among older adults. In doing so, we highlight approaches that appear to hold promise in real-world settings with older individuals. We conducted a tailored literature review specifically on approaches to improve sleep quality among older adults, with emphasis on those integrating stress management...

BACKGROUND: Previously published studies reported benefits of computer-assisted surgery (CAS) in terms of radiographic implant position in TKA, but whether these improvements result in clinically important survival differences or functional differences that a patient might perceive at a minimum 10-year followup remains largely unknown. QUESTIONS/PURPOSES: We performed a prospective randomized trial and asked whether CAS (1) improved survival free from aseptic loosening; and (2) demonstrated any clear difference in patient-reported outcomes at latest followup using validated outcome measures at minimum 10-year followup...

Meditation, as taught by most schools of practice, consists of a set of heterogeneous techniques. We wanted to assess if EEG profiles varied across different meditation techniques, proficiency levels and experience of the practitioners. We examined EEG dynamics in Vipassana meditators (Novice, Senior meditators and Teachers) while they engaged in their traditional meditation practice (concentration, mindfulness and loving kindness in a structured manner) as taught by S.N. Goenka. Seniors and Teachers (vs Novices) showed trait increases in delta (1-4 Hz), theta-alpha (6-10 Hz) and low-gamma power (30-40 Hz) at baseline rest; state-trait increases in low-alpha (8-10 Hz) and low-gamma power during concentrative and mindfulness meditation; and theta-alpha and low-gamma power during loving-kindness meditation...

BACKGROUND: The national competence-based catalogue of learning-goals in surgery (NKLC) defines competence levels for each of its 230 goals, including "competence level in 1: factual knowledge" up to "competence level 3: independent action". Aside from the cumulative examinations influencing the learning behaviour of students, those teaching targets do not affect the second state examination. This study analyses the extent to which the questions of the German second medical licensing examination compiled by the IMPP (central German institute for medical and pharmaceutical examinations) are congruent with the trauma-surgical and orthopaedic learning goals in the NKLC, in which this thematic focus is emphasised...
