PURPOSE: During brain tumor surgery, planning and guidance are based on preoperative images which do not account for brain-shift. However, this deformation is a major source of error in image-guided neurosurgery and affects the accuracy of the procedure. In this paper, we present a constraint-based biomechanical simulation method to compensate for craniotomy-induced brain-shift that integrates the deformations of the blood vessels and cortical surface, using a single intraoperative ultrasound acquisition...

Daily activities require agents to interact with each other, such as during collision avoidance. The nature of visual information that is used for a collision free interaction requires further understanding. We aim to manipulate the nature of visual information in two forms, global and local information appearances. Sixteen healthy participants navigated towards a target in an immersive computer-assisted virtual environment (CAVE) using a joystick. A moving passive obstacle crossed the participant?s trajectory perpendicularly at various pre-defined risks of collision distances...

47,XXY (Klinefelter Syndrome) is associated with a spectrum of complex clinical needs that are associated with variable physical, neurocognitive and psychosocial aspects. For patients and families affected by this sex chromosome trisomy, navigation of health care services is difficult due to lack of 47,XXY awareness among many health care providers and little evidence to support endocrine and additional treatment plans. While endocrine management of androgen deficiency has been the mainstay of treatment for patients from puberty through adulthood, testosterone replacement, alone, fails to mitigate many symptoms and issues...

Transfer from pediatric to adult health care is a significant life event for youth with chronic medical conditions. Unfortunately, youth may not be well prepared to navigate the shift in health care services, increasing their risk for loss to follow up and poor health outcomes. This review explores transition in care through the lens of type 1 diabetes, highlighting current practices and guidelines and offering recommendations for future consideration. Limited evidence suggests that transition programs that focus on strategies to prepare youth developmentally and equip the health care system appropriately have positive impact on the hand off of care, and health outcomes...

Reproduction in social insect societies reflects a delicate balance between cooperation and conflict over offspring production, and worker reproduction is widespread even in species showing strong reproductive skew in favor of the queen. To navigate these conflicts, workers are predicted to develop the means to estimate the queen's fecundity - potentially through behavioral and/or chemical cues - and to adjust their reproduction to maximize their fitness. Here, we introduced bumble bee, Bombus impatiens, workers to queens of different mating and reproductive status and examined worker reproduction and expression levels of two genes which were previously shown to be sensitive to the presence of the queen, vitellogenin and Krüppel-homolog 1...

BACKGROUND: Computer navigation-assisted surgery for musculoskeletal tumors has shown to reduce the risk of intra-lesional margins in resection. Experiences with this method are still limited to smaller case series. METHOD: We reviewed our first experiences in 24 patients in whom computer navigation-assisted surgery had been performed. In 7 of these patients (6 male and 1 female), this has influenced the surgical treatment plan and navigation was used for both tumor resection and reconstruction...

PURPOSE: Through a comparison with the axial orientation, we aimed to evaluate the role of coronal high-resolution diffusion-weighted imaging (DWI) in acute optic neuritis based on diagnostic accuracy and the reproducibility of apparent diffusion coefficient (ADC) measurements. METHODS: Orbital DWI, using readout-segmented, parallel imaging, and 2D navigator-based reacquisition (RESOLVE-DWI), was performed on 49 patients with acute vision loss. The coronal (thickness = 3 mm) and axial (thickness = 2 mm) diffusion images were evaluated by two neuroradiologists retrospectively...

The interprofessional nature of the Primary Care Behavioral Health (PCBH) model invites potential conflicts between different ethical guidelines and principles developed by separate professional disciplines. When the foundational model of care and training on which ethical principles were developed shifts, the assumptions underlying the guidance also shifts, revealing gaps and mismatches. This article reviews the extant literature in this realm, and proposes a more unifying set of ethical guidance for interprofessional, integrated primary care practice...

Signy Sheldon, Alexa Ruel
Navigated routes can be recalled by remembering a schematic layout or with additional sensory and perceptual details, engaging episodic memory processes. In this study, we contrasted the effects of these remembering approaches on retrieving real-world navigated routes, the impact on flexibly using familiar route information and on learning new spatial representations. In a within-subjects design, participants were oriented to recall familiar routes under two remembering conditions-a detail condition that promoted episodic memory processes and a gist condition in which routes were recalled via schematic processes...

BACKGROUND CONTEXT: Minimally invasive spine surgery has become increasingly popular in clinical practice, and it offers patients the potential benefits of reduced blood loss, wound pain, and infection risk and also diminishes the loss of working time and length of hospital stay. However, surgeons require more intraoperative fluoroscopy and ionizing radiation exposure during minimally invasive spine surgery for localization, especially for guidance in instrumentation placement. In addition, computer navigation is not accessible in some facility-limited institutions...

Training protocols designed to improve dual-task performance of an obstacle crossing and auditory Stroop task (OBS+Stroop) were tested. In Experiment  1 , following baseline collection of OBS+Stroop trials, proximally related walking training was performed, and participants were then retested on the OBS+Stroop test. After training, participants adopted a more cautious obstacle crossing strategy, indicating a potentially safer navigation strategy. Transfer effects from distally related training were then examined (Experiment  2 ); a computer game training paradigm was examined using the same testing protocol as Experiment  1 ...

Apical periodontitis, the inflammation of periapical tissue, commonly requires root canal treatment to achieve apical healing. However, if it is accompanied by pulp canal calcification, the treatment becomes complicated, and locating the root canal can be challenging. This case report describes a novel approach for treating a molar with pulp canal calcification and apical pathology. Due to the risk of perforation during treatment, a digitally printed template was used to assist in accurately locating the root canal...

In the last decade, the humanities have been shrinking in number of students, percent of faculty, and in number of degrees awarded. Humanities students also earn lower salaries than their STEM-prepared peers. At the same time, the health humanities have been in ascendance over the last fifteen years. The number of majors, minors and certificates has increased 266% in that time frame, attracting large numbers of students and preparing future patients, lay caregivers, and health care providers to interact with a complicated and dehumanized medical system...
