Mireli A Mongen, Peter W A Willems
OBJECT: In the past, the accuracy of surface matching has been shown to be disappointing. We aimed to determine whether this had improved over the years by assessing application accuracy of current navigation systems, using either surface matching or point-pair matching. METHODS: Eleven patients, scheduled for intracranial surgery, were included in this study after a power analysis had shown this small number to be sufficient. Prior to surgery, one additional fiducial marker was placed on the scalp, the "target marker," where the entry point of surgery was to be expected...

BACKGROUND: Endovascular technological advances have revolutionized the field of neurovascular surgery and have become the mainstay of treatment for many cerebrovascular pathologies. Digital subtraction angiography (DSA) is the 'gold standard' for visualization of the vasculature and deployment of endovascular devices. Nonetheless, with recent technological advances in optics, angioscopy has emerged as a potentially important adjunct to DSA. Angioscopy can offer direct visualization of the intracranial vasculature, and direct observation and inspection of device deployment...

The development of core outcome sets (COS), i.e. a minimum set of 'core outcomes' that should be measured and reported in all trials or clinical practice of a specific condition, in dermatology is gathering pace. A total of 44 dermatology-related COS projects have been registered in the online Core Outcome Measures in Effectiveness Trials (COMET) database (http://www.comet-initiative.org/studies/search), and include studies on 26 different skin diseases. With the increasing number of COS in dermatology, care is needed to ensure the delivery of high quality COS that meet quality standards based on state of the art methodology...

Chakapan Promsopa, Usaporn Prapaisit
BACKGROUND: Lodgment of a bullet within the orbit is uncommon. The decision to remove these objects poses a challenge to surgeons due to a high risk of complications. Currently, endoscopic transnasal surgery with navigator assistance facilitates the localization of foreign bodies allowing their safe removal with minimal surrounding tissue damage or optic nerve injury. CASE PRESENTATION: We describe a case of a 26-year-old Thai woman with a chronic intraorbital foreign body located within her medial intraconal space...

INTRODUCTION: Following the investigation into the Mid Staffordshire Hospital (United Kingdom) and the subsequent Francis reports (2013 and 2015), all healthcare staff, including students, are called upon to raise concerns if they are concerned about patient safety. Despite this advice, it is evident that some individuals are reluctant to do so and the reasons for this are not always well understood. STUDY AIM: This research study provides an insight into the factors that influence student nurses to speak up or remain silent when witnessing sub-optimal care...

Nicholas D Kathman, Jessica L Fox
The reduced hindwings of flies, known as halteres, are specialized mechanosensory organs that detect body rotations during flight. Primary afferents of the haltere encode its oscillation frequency linearly over a wide bandwidth and with precise phase-dependent spiking. However, it is not currently known whether information from haltere primary afferent neurons is sent to higher brain centers where sensory information about body position could be used in decision making, or whether precise spike timing is useful beyond the peripheral circuits that drive wing movements...

Early engagement in mental health intervention is critical, yet the vast majority of children who are experiencing mental health concerns are not receiving needed services. Pediatric primary care clinics have been recognized as an ideal setting in which to identify and address mental health problems early, although engagement in mental health services within primary care and in community-based settings remains low. Navigators, or individuals with experience in navigating the mental health system, have been highlighted as promising partners in efforts to improve engagement in mental health services...

BACKGROUND: There is a new research reported that the technology for navigating the catheter, which is eccentric or tangentially angled to the long axis of a CAS(Carotid Artery Stent). In the clinical practices, we found that there is still existed resistance when the 8F guiding catheter crossing the balloon, even if it is partially expanded. Therefore, we intended to improve the operating procedure by utilizing a smaller balloon with a diameter of 2 mm. The smaller balloon can navigate the guiding catheter re-access the angled junction with minimal resistance after it is fully expanded...

INTRODUCTION: Investigation tools used in occupational health and safety events need to support evidence-based judgments, especially when employed within biasing contexts, yet these tools are rarely empirically vetted. A common workplace investigation tool, dubbed for this study the "Cause Analysis (CA) Chart," is a checklist on which investigators select substandard actions and conditions that apparently contributed to a workplace event. This research tests whether the CA Chart supports quality investigative judgments...

There is a strong demand in the oil and gas industry to develop alternatives to manual inspection. This paper presents AeroX, a novel aerial robotic manipulator that provides physical contact inspection with unprecedented capabilities. AeroX has a semi-autonomous operation, which provides interesting advantages in contact inspection. In the free-flight mode, the pilot guides the robot until performing contact with its end-effector on the surface to be inspected. During contact, AeroX is in its fully-autonomous global navigation satellite system (GNSS)-free contact⁻flight mode, in which the robot keeps its relative position w...

For a significant number of people with visual impairments, public transport plays an important role in productivity, community participation, and independence, since it may be the only feasible mobility option to participate in their education, work, medical care, food, and to attend many other places in their community. To use the public bus system safely, effectively, and autonomously, these people need to collect information about their physical environment and visible information at stops and terminals, such as timetables, routes, etc...

Research has evidenced a marked increase in the prevalence of cancer among younger people with up to one in five, parenting children under the age of 18 years of age. When a parent is diagnosed with cancer they experience fears and anxieties as they attempt to simultaneously manage their role as a parent, with the illness experience. Parents have expressed difficulties in knowing how to communicate appropriately with their children throughout the illness trajectory as they are primarily focused on protecting or shielding their children from knowledge of the illness...

INTRODUCTION: Surgical management of adolescent idiopathic scoliosis in spite of usually favourable outcomes is still a major operation. Therefore, efforts are being undertaken to minimalize the procedure, reduce the surgical trauma and postoperative convalescence. The study was designed to compare posterior minimal invasive surgery using navigation based on intraoperative 3D imaging and standard open instrumented fusion in Lenke 5C idiopathic scoliosis treatment. MATERIALS AND METHODS: From eight patients with Lenke 5C curves planned for posterior correction and instrumented fusion, four were treated with minimally invasive and four had open procedure...
