Hei-Tung Sung, Leif Sigerson, Cecilia Cheng
In the summer of 2016, the widespread popularization of the game Pokémon Go brought the public's attention to the possible socialization benefits associated with location-based mobile games (LBMGs), yet no studies to date have investigated this issue. LBMGs deserve greater research attention because this type of game provides a unique gaming experience that encourages players to leave their homes and navigate around their neighborhood. This distinctive feature may promote more face-to-face interactions among LBMG players...

Pacific Island veterans suffer from greater severity of posttraumatic stress disorder (PTSD) compared with Caucasian veterans but face substantial barriers to mental health care. However, the factors that may dissuade or facilitate veterans in the Pacific Islands from seeking mental health care are not known. The main aim of this study was to identify how internal and external factors interact to impact wounded warriors' access to and use of mental health services. Veterans residing in 5 rural Pacific Island locations were mailed recruitment materials...

While donation after circulatory death (DCD) has expanded options for organ donation, many who wish to donate are still unable to do so. We conducted face-to-face interviews with family members (n=15) who had direct experience with unsuccessful DCD and five focus groups with professionals involved in the donation process. We used qualitative content analysis to characterize harms of non-donation as perceived by participants. Participants reported a broad spectrum of harms impacting organ recipients, donors and donor families...

Individuals diagnosed with developmental disability and mental illness (a "dual diagnosis") contend with multiple challenges and system-related barriers. Using an interpretive description approach, separate qualitative interviews were conducted with adults with a dual diagnosis (n = 7) and their caregiving parents (n = 8) to examine care-related experiences. Results indicate that individuals with a dual diagnosis and their families experience misunderstanding and stigma. Families provide informal complex care amid insufficient and uncoordinated services but are often excluded from formal care planning...

Motor-imagery tasks are a popular input method for controlling brain-computer interfaces (BCIs), partially due to their similarities to naturally produced motor signals. The use of functional near-infrared spectroscopy (fNIRS) in BCIs is still emerging and has shown potential as a supplement or replacement for electroencephalography. However, studies often use only two or three motor-imagery tasks, limiting the number of available commands. In this work, we present the results of the first four-class motor-imagery-based online fNIRS-BCI for robot control...

Zika virus (ZIKV) has been of major international public health concern following large outbreaks in the Americas occurring in 2015-2016. Most notably, ZIKV has been seen to pose dangers in pregnancy due to its association with congenital abnormalities such as microcephaly. Numerous experimental approaches have been taken to address how the virus can cross the placenta, alter normal fetal development, and disrupt specific cellular functions. Many areas concerning the mechanisms of transmission, especially from mother to fetus, are largely unknown but demand further research...

REVIEW
Suresh Jesuthasan
The thalamus is one of the most highly connected hubs of the vertebrate brain, with roles in perception, arousal, navigation, memory and consciousness. One connection that is missing from contemporary maps is a link to the habenula. This link was reported in the early part of the last century, but appears to have slipped into obscurity. Here, I review the evidence for the existence of this innervation and consider the potential roles it could play. In particular, the possibility that this pathway is involved in non-visual responses to ambient illumination is examined...

Self-propelled micro- and nanoscale robots represent a rapidly emerging and fascinating robotics research area. However, designing autonomous and adaptive control systems for operating micro-/nanorobotics in complex and dynamically-changing environments, which is a highly demanding feature, is still an unmet challenge. Here we describe a smart microvehicle for precise autonomous navigation in complicated environments and traffic scenarios. The fully autonomous navigation system of the smart microvehicle is composed of a microscope-coupled CCD camera, an artificial intelligence planner, and a magnetic field generator...

Monitoring one's safety during low vision navigation demands limited attentional resources which may impair spatial learning of the environment. In studies of younger adults, we have shown that these mobility monitoring demands can be alleviated, and spatial learning subsequently improved, via the presence of a physical guide during navigation. The present study extends work with younger adults to an older adult sample with simulated low vision. We test the effect of physical guidance on improving spatial learning as well as general age-related changes in navigation ability...

Non-medical prescribing is now well established in a number of countries. Because prescribing has traditionally been viewed as a medical role, there are inevitable interprofessional boundary tensions when non-medical prescribing is introduced. In New Zealand, enabling legislation has allowed nurse practitioners to apply for prescriptive authority after undertaking appropriate educational preparation. This study explored the experiences and perspectives of one of the first cohorts of nurse prescribers and their strategies in establishing the role and negotiating the associated professional boundaries...

Human beings differ considerably in their ability to orient and navigate within the environment, but it has been difficult to determine specific causes of these individual differences. Permanent, stable landmarks are thought to be crucial for building a mental representation of an environment. Poor, compared to good, navigators have been shown to have difficulty identifying permanent landmarks, with a concomitant reduction in functional MRI (fMRI) activity in the retrosplenial cortex. However, a clear association between navigation ability and the learning of permanent landmarks has not been established...

For robots to successfully integrate into everyday life, it is important that they can be effectively controlled by laypeople. However, the task of manually controlling mobile robots can be challenging due to demanding cognitive and sensorimotor requirements. This research explores the effect that the built environment has on the manual control of domestic service robots. In this study, a virtual reality simulation of a domestic robot control scenario was developed. The performance of fifty novice users was evaluated, and their subjective experiences recorded through questionnaires...

PURPOSE: The target registration error (TRE) is a crucial parameter to estimate the potential usefulness of computer-assisted navigation intraoperatively. Both image-to-patient registration on base of rigid-body registration and TRE prediction methods are available for spatially isotropic and anisotropic data. This study presents a thorough validation of data obtained in an experimental operating room setting with CT images. METHODS: Optical tracking was used to register a plastic skull, an anatomic specimen, and a volunteer to their respective CT images...

BACKGROUND: The spatial and directional accuracy of the positioning of pedicle screws in the lumbosacral spine with conventional open surgery assessed by computed tomography (CT) has been published in several studies, systematic reviews and meta-analyses with a short-term follow-up. Inaccurate pedicle screw insertion may cause neurologic symptoms and weakens the construct. METHODS: The data of 147 patients operated on with transpedicular screw fixation based on anatomical landmarks, supported by fluoroscopy, by a senior neurosurgeon in our clinic between 2000 and 2010 were analyzed retrospectively...

REVIEW
Evatte T Sciberras-Lim, Anthony J Lambert
Every day we are faced with an overwhelming influx of visual information. Visual attention acts as the filtering mechanism that enables us to focus our limited neural resources, by selectively processing only the most relevant and/or salient aspects of our visual environment. The ability to shift attention to the most behaviorally relevant items enables us to successfully navigate and interact with our surroundings. The dorsal visual stream is important for the rapid and efficient visuospatial orienting of attention...

We describe the importance of collaboration between multiple surgical specialties in managing a complex case of sight-threatening severe proptosis in a young woman with type 2 neurofibromatosis (NF2) complicated by pre-existing contralateral blindness. Trans-nasal and lateral orbital surgical approaches were aided by stereotactic navigation to debulk a large frontal/sphenoid wing meningioma, which had been exerting pressure onto the right globe and optic nerve. The patient made an excellent postoperative recovery along with preserved residual visual acuity, normal neurology and a good aesthetic outcome...
