REVIEW
Gema Rebolleda, Aki Kawasaki, Victoria de Juan, Noelia Oblanca, Francisco Jose Muñoz-Negrete
PURPOSE OF REVIEW: Mild papilledema may be difficult to distinguish by clinical observation from pseudopapilledema. An accurate diagnosis is critical to avoid invasive workup and unwarranted treatment. In this review, we focus on the development and subsequent role of optical coherence tomography (OCT) in detecting and differentiating optic nerve head drusen (ONHD) from papilledema and other causes of acquired swelling of the optic disc. RECENT FINDINGS: Newer OCT technologies which permit deeper penetration to improve detection of ONHD were also reviewed...

After the Fukushima Daiichi Nuclear Power Plant accident, the vertical distribution of radiocesium in soil has been investigated to better understand the behavior of radiocesium in the environment. The typical method used for measuring the vertical distribution of radiocesium is troublesome because it requires collection and measurement of the activity of soil samples. In this study, we established a method of estimating the vertical distribution of radiocesium by focusing on the characteristics of gamma-ray spectra obtained via aerial radiation monitoring using an unmanned helicopter...

Optical coherence tomography (OCT) is a valuable ancillary test in the diagnosis and management of chorioretinal disease. The evaluation of choroid thickness using OCT has become the focus of clinical applications. We report a linear artifact that acts as a confounding factor in choroidal thickness measurements by enhanced depth imaging OCT. We found that the linear artifact is located stably at a depth of 485 μm beneath the retinal pigment epithelium in 81.88% of subjects. The study suggested that the linear artifact was a confounding factor in assessing choroidal thickness and that caution should be used in the interpretation of the choroidal thickness, especially when it is approximately 485 μm...

This paper describes the design and implementation of a multiple view stereoscopic 3D vision system and a supporting infant tracker pipeline to track limb movement in natural play environments and identify potential metrics to quantify movement behavior. So far, human pose estimation and tracking with 3D cameras has been focused primarily on adults and cannot be directly extended to infants because of differences in visual features such as shapes, sizes and appearance. With rehabilitation in mind, we propose a portable, compact, markerless, low cost and high resolution 3D vision system and a tracking algorithm that exploits infant appearance attributes and depth information...

HIV self-testing may encourage greater uptake of testing, particularly among key populations and other high-risk groups, but local community perceptions will influence test uptake and use. We conducted 33 in-depth interviews and 6 focus group discussions with healthcare providers and community members in high-risk fishing communities (including sex workers and fishermen) and lower-risk mainland communities in rural Uganda to evaluate values and preferences around HIV self-testing. While most participants were unfamiliar with HIV self-testing, they cited a range of potential benefits, including privacy, convenience, and ability to test before sex...

The scramble for available places to study medicine in Germany continues. One of the core points within the "Master Plan 2020", which has been recently adopted, is the reform of teaching concepts at German medical faculties. In the future, students of human medicine are to be trained primarily based upon competence-oriented, integrated curricula. The present paper is intended to present modern teaching concepts and methods, as well as current examination formats, which play a special role in student training in orthopaedics and traumatology...

While nurses and midwives are in a unique position to identify and help victims of IPV, since they are often their first point of contact in the healthcare system, they need appropriate training. This study sought to examine the presence of IPV-related contents and the depth to which they are addressed in the bachelor's degree in Nursing and in the Midwifery specialisation programme. The study also explored lecturers' motivations for including IPV in their subjects. The methodology employed was qualitative...

Yuta Itoh, Takumi Hamasaki, Maki Sugimoto
We propose an occlusion compensation method for optical see-through head-mounted displays (OST-HMDs) equipped with a singlelayer transmissive spatial light modulator (SLM), in particular, a liquid crystal display (LCD). Occlusion is an important depth cue for 3D perception, yet realizing it on OST-HMDs is particularly difficult due to the displays' semitransparent nature. A key component for the occlusion support is the SLM-a device that can selectively interfere with light rays passing through it. For example, an LCD is a transmissive SLM that can block or pass incoming light rays by turning pixels black or transparent...

Boiling histotripsy is a method of focused ultrasound surgery that noninvasively applies millisecond-length pulses with high-amplitude shock fronts to generate liquefied lesions in tissue. Such a technique requires unique outputs compared to a focused ultrasound thermal therapy apparatus, particularly to achieve high in situ pressure levels through intervening tissue. This article describes the design and characterization of a system capable of producing the necessary pressure to transcutaneously administer boiling histotripsy therapy through clinically relevant overlying tissue paths using pulses with duration up to 10 ms...

To develop the high performance filters and duplexers required for recent LTE frequency bands in mobile handsets, a surface acoustic wave (SAW) resonator is needed that have higher quality (Q) and a lower temperature coefficient of frequency (TCF). To achieve this, the authors focused on acoustic energy confinement in the depth direction for a rotated Y-X LiTaO3 (LT) substrate. Characteristics of multi-layered substrates with low impedance and high impedance layers under LT layer were studied numerically in terms of acoustic energy distribution, phase velocity, coupling coefficient and temperature characteristics employing a finite element method (FEM) simulation...

BACKGROUND: The impact of untreated syphilis during pregnancy on neonatal health remains a major public health threat worldwide. Given the high prevalence of syphilis during pregnancy in Zambia and Democratic Republic of Congo (DRC), the Preventive Congenital Syphilis Trial (PCS Trial), a cluster randomized trial, was proposed to increase same-day screening and treatment of syphilis during antenatal care visits. To design an accepted and feasible intervention, we conducted a qualitative  formative research...

The development of techniques for efficiently confining energy in the visible and infrared spectral regions to the deep subwavelength spatial scale with dimensions as small as a few nanometers would have great significance for scientific research and engineering practices. Such an ability to manipulate light is impossible for conventional dielectric lenses due to the diffraction limit. Here, we propose a metallic graded-index (MGRIN) lens formed by an array of coupled metallic waveguides with identical nanoscale widths embedded by index-varying dielectrics to enable the optical nanofocusing...

PURPOSE: The integration of mental health specialists into primary care has been widely advocated to deliver evidence-based mental health care to a defined population while improving access, clinical outcomes, and cost efficiency. Integrated care has been infrequently and inconsistently translated into real-world settings; as a result, the key individual components of effective integrated care remain unclear. METHOD: This article reports findings from a qualitative study that explored provider and client experiences of integrated care...

Although Graves' disease has been recognised for more than 100 years, its physiopathological mechanisms are incompletely understood. Treatment strategies today mainly focus on suppression of thyroid hormone production by use of antithyroid drugs or radio-iodine, but neglect the underlying immunological mechanisms. Although Graves' disease is often seen as a prototype for an autoimmune mechanism, it is more likely to be a heterogeneous syndrome showing characteristics of both autoimmunity and immunodeficiency...

BACKGROUND: Various explanations account for suicide incidents, and some patients continue to attempt afterwards and others never again. The suicide mortality rate increases with the number of serious attempts. The prevention of secondary attempt of suicide should be an important approach to reduce suicide mortality. However, the characteristics of the targeted population of repeated suicide attempters are understudied. METHODS: This was a cross-sectional data collection from hospital emergency room from patients who had either attempted suicide for the first time (n=721) or for two or more times (n=70)...
