Regenerative medicine offers potentially ground-breaking treatments of blindness and low vision. However, as new methodologies are developed, a critical question will need to be addressed: how do we monitor in vivo for functional success? In the present study, we developed novel behavioral assays to examine vision in a vertebrate model system. In the assays, zebrafish larvae are imaged in multiwell or multilane plates while various red, green, blue, yellow or cyan objects are presented to the larvae on a computer screen...

BACKGROUND: Current wound assessment practices are lacking on several measures. For example, the most common method for measuring wound size is using a ruler, which has been demonstrated to be crude and inaccurate. An increase in periwound temperature is a classic sign of infection but skin temperature is not always measured during wound assessments. To address this, we have developed a smartphone application that enables non-contact wound surface area and temperature measurements. Here we evaluate the inter-rater reliability and accuracy of this novel point-of-care wound assessment tool...

Minimal literature exists describing the process for development of a Joint Commission comprehensive spine surgery program within a community hospital health system. Components of a comprehensive program include structured communication across care settings, preoperative education, quality outcomes tracking, and patient follow-up. Organizations obtaining disease-specific certification must have clear knowledge of the planning, time, and overall commitment, essential to developing a successful program. Health systems benefit from disease-specific certification because of their commitment to a higher standard of service...

The growth of health care simulation in schools of medicine and nursing is noteworthy, as is the increasingly sophisticated simulation technology, support from funding agencies and foundations for research, well-attended annual conferences, and continued interest of accreditation and certification groups. Yet there are concerns preventing the full value of health care simulation to be realized when examined from a patient safety perspective. Basic questions are asked by funders of patient safety research when assessing past simulation projects undertaken to advance patient safety: Are the safety and quality of care to patients actually improved, and is something new being learned regarding the optimal use of simulation? Concerns focus on pursuing the right research questions to learn something new about the most effective use of simulation; doing more with simulation than simply providing an interesting, stand-alone educational experience; attending more seriously to how skill acquisition, maintenance, and progression get managed; and encouraging investigators, funders, and reviewers to expand their vision regarding what constitutes important inquiry and evidence in health care simulation...

PURPOSE OF REVIEW: To review the systemic vasculitides and associated ocular manifestations with emphasis on publications within the last 12 months. RECENT FINDINGS: There are multiple case reports demonstrating atypical ocular manifestations of systemic vasculitis. Often the eye findings are the initial presentation of the disorder and require a high degree of clinical suspicion to evaluate further as these conditions can compromise vision but some may also be life threatening...

Laura J Speed, Asifa Majid
Olfaction is often considered a vestigial sense in humans, demoted throughout evolution to make way for the dominant sense of vision. This perspective on olfaction is reflected in how we think and talk about smells in the West, with odor imagery and odor language reported to be difficult. In the present study we demonstrate odor cognition is superior in odor-color synaesthesia, where there are additional sensory connections to odor concepts. Synaesthesia is a neurological phenomenon in which input in 1 modality leads to involuntary perceptual associations...

To what extent are shifts of attention driven by encoding of visual-spatial landmarks, associated with useful locations, or by encoding of environmental cues that act as symbolic representations, providing information about where to look next? In Experiment 1 we found that when cues were presented with a long exposure time (300 ms) attention shifts were driven by the symbolic identity of cue stimuli, independently of their visual-spatial (landmark) features; but when cues were exposed very briefly, (66 ms), attention shifts were independent of symbolic information, and were driven instead by visual landmark features...

A bio-micromanipulation system is designed for manipulating micro-objects with a length scale of tens or hundreds of microns based on stereo light microscope. The world coordinate reconstruction of points on the surface of micro-objects is an important goal for the micromanipulation. Traditional pinhole camera model is applied widely in macrocomputer vision. However, this model will output bad data with remarkable error if it is directly used to reconstruct three-dimensional world coordinates for stereo light microscope...

Age-related macular degeneration (AMD) is the leading cause of vision loss among the elderly. Atrophic AMD, including early, intermediate and geographic atrophy (GA), accounts for ~90% of all cases. It is a multifactorial degeneration characterized by chronic inflammation, oxidative stress and aging components. Although no FDA-approved treatment yet exists for the late stage of atrophic AMD, multiple pathological mechanisms are partially known and several promising therapies are in various stages of development...

The author contends that, contrary to the usual perception that Winnicott followed a linear progression "through pediatrics to psychoanalysis," Winnicott's vision was always a psychoanalytic one, even during his early pediatric work. His place in the development of psychoanalytic theory is highlighted, and the author discusses such key Winnicottian concepts as transitional space, the false self, and the use of the object. Winnicott's unique approach to the form and value of analytic interpretation is particularly emphasized, and his thoughts on the treatment of depression are also addressed, as well as his distinction between regression and withdrawal...

Pharmacovogilance policy, methods and practice require transformation at all levels to create an integrated, comprehensive, continuously improving system, fulfilling the broader remit of overall healthcare vigilance. In pursuit of this vision, energetic measures, including active engagement with patients, are needed to reduce our ignorance about many aspects of patients' experience of medical therapies and their outcomes, including the benefits, but especially the extensive harm known to be caused by medical interventions...

We examined audiovisual and visuotactile integration in the central and peripheral visual field using visual fission and fusion illusions induced by sounds or taps. The fission illusion occurs when a single flash is perceived as two flashes if paired with two beeps or taps; the fusion illusion, by contrast, occurs when two flashes are perceived as a single flash if the flashes are paired with a single beep or tap. Beeps and taps induced similar patterns of illusions: the fission illusion was larger in the periphery than in the center, whereas the fusion illusion was larger in the center than in the periphery...
