CONTEXT: Women with disabilities experience a higher rate of adverse pregnancy outcomes than women without disabilities. Preventing or delaying pregnancy when that is the best choice for a woman is a critical strategy to reducing pregnancy-related disparities, yet little is known about current contraceptive use among women with disabilities. METHODS: A cohort of 545 reproductive-age women with physical disabilities (i.e., difficulty walking, climbing, dressing or bathing) or sensory disabilities (i...

BACKGROUND: Despite recommendations that women give birth with a skilled birth attendant (SBA), 70% of births in Guatemala occur outside health facilities with informally trained traditional birth attendants (TBAs). To increase SBA in rural, indigenous communities, a professional midwifery school accredited by the government is scheduled to open in 2017. Drawing from Filby's model on barriers to the successful integration of professional midwifery into health systems, this paper aims to identify threats - and facilitators-toward professional midwifery's re-introduction in Guatemala...

We propose a system to infer binocular disparity from a monocular video stream in real-time. Different from classic reconstruction of physical depth in computer vision, we compute perceptually plausible disparity, that is numerically inaccurate, but results in a very similar overall depth impression with plausible overall layout, sharp edges, fine details and agreement between luminance and disparity. We use several simple monocular cues to estimate disparity maps and confidence maps of low spatial and temporal resolution in real-time...

Binocular stereopsis is one of the primary cues for three-dimensional (3D) vision in species ranging from insects to primates. Understanding how the brain extracts depth from two different retinal images represents a tractable challenge in sensory neuroscience that has so far evaded full explanation. Central to current thinking is the idea that the brain needs to identify matching features in the two retinal images (i.e., solving the "stereoscopic correspondence problem") so that the depth of objects in the world can be triangulated...

The principle that global human identity and dignity supersede other values is a broadly accepted conviction that guides practice and policies in the realm of human health in most of the world. An assessment of the level of success that Israel has achieved in health, in the face of formidable challenges, including rapid population growth, diverse and often divided ethnic affiliations, and existential security threats, leads us to propose that extension of this principle of global human identity and dignity, together with the objective of a decent society, as overriding values beyond health to other domains of human endeavour within Israel and in its relations with neighbouring peoples, represents an entirely achievable imperative...

Purpose: The impairment of visual functions is one of the most common complaints following mild traumatic brain injury (mTBI). Traumatic brain injury-associated visual deficits include blurred vision, reading problems, and eye strain. In addition, previous studies have found evidence that TBI can diminish early cortical visual processing, particularly for second-order stimuli. We investigated whether cortical processing of binocular disparity is also affected by mTBI. Methods: In order to investigate the influence of mTBI on global stereopsis, we measured the quick Disparity Sensitivity Function (qDSF) in 22 patients with mTBI...

BACKGROUND: Binocular summation (BiS), or improvement in binocular vision exceeding the better eye alone, is affected by strabismus. Being easily measured, BiS may be a useful indicator for subjective outcomes like stereopsis in strabismus. This study aims to investigate the relationship between BiS and measures of control of intermittent exotropia (IXT). METHODS: Patients with IXT were recruited before undergoing strabismus surgery and underwent tests of binocular and monocular high- and low-contrast visual acuity, stereopsis at distance and near, and Newcastle Control Score (NCS), a score developed by incorporating home control and clinic control criteria into a control rating scale...

In December 2016, the American Society of Clinical Oncology (ASCO) Board of Directors approved the ASCO Strategic Plan to Increase Racial and Ethnic Diversity in the Oncology Workforce. Developed through a multistakeholder effort led by the ASCO Health Disparities Committee, the purpose of the plan is to guide the formal efforts of ASCO in this area over the next three years (2017 to 2020). There are three primary goals: (1) to establish a longitudinal pathway for increasing workforce diversity, (2) to enhance ASCO leadership diversity, and (3) to integrate a focus on diversity across ASCO programs and policies...

PURPOSE: To assess socioeconomic disparity in global burden of cataract, by using disability-adjusted life years (DALYs). DESIGN: International, comparative burden-of-disease study. METHODS: Published data on national age-standardized DALY rates caused by cataract and human development index (HDI) between 1990 and 2013 were obtained. The association between age-standardized DALY rates and HDI in 2013 was analyzed. The health-related Gini coefficients and the concentration indexes were calculated to explore the trends in between-country inequality in cataract burden from 1990 to 2013...

Binocular stereopsis is the ability of a visual system, belonging to a live being or a machine, to interpret the different visual information deriving from two eyes/cameras for depth perception. From this perspective, the ground-truth information about three-dimensional visual space, which is hardly available, is an ideal tool both for evaluating human performance and for benchmarking machine vision algorithms. In the present work, we implemented a rendering methodology in which the camera pose mimics realistic eye pose for a fixating observer, thus including convergent eye geometry and cyclotorsion...

Depth perception in near viewing strongly relies on the interpretation of binocular retinal disparity to obtain stereopsis. Statistical regularities of retinal disparities have been claimed to greatly impact on the neural mechanisms that underlie binocular vision, both to facilitate perceptual decisions and to reduce computational load. In this paper, we designed a novel and unconventional approach in order to assess the role of fixation strategy in conditioning the statistics of retinal disparity. We integrated accurate realistic three-dimensional models of natural scenes with binocular eye movement recording, to obtain accurate ground-truth statistics of retinal disparity experienced by a subject in near viewing...

A robust literature documents the impact of poverty on child development and lifelong health, well-being and productivity. Racial and ethnic minority children continue to bear the burden of poverty disproportionately. Evidence-based parenting interventions in early childhood have the potential to attenuate risk attributable to poverty and stress. To reduce racial, ethnic, and socioeconomic disparities in the USA, parenting interventions must be accessible, engaging, and effective for low-income families of color living in large urban centers...

The rise and fall of artificial neural networks is well documented in the scientific literature of both computer science and computational chemistry. Yet almost two decades later, we are now seeing a resurgence of interest in deep learning, a machine learning algorithm based on multilayer neural networks. Within the last few years, we have seen the transformative impact of deep learning in many domains, particularly in speech recognition and computer vision, to the extent that the majority of expert practitioners in those field are now regularly eschewing prior established models in favor of deep learning models...

The division of labor between the dorsal and the ventral visual stream in the primate brain has inspired numerous studies on the visual system in humans and in nonhuman primates. However, how and under which circumstances the two visual streams interact is still poorly understood. Here we review evidence from anatomy, modelling, electrophysiology, electrical microstimulation (EM), reversible inactivation and functional imaging in the macaque monkey aimed at clarifying at which levels in the hierarchy of visual areas the two streams interact, and what type of information might be exchanged between the two streams during three-dimensional (3D) object viewing...

Development and implementation of effective, sustainable, and scalable interventions that advance equity could be propelled by innovative and inclusive partnerships. Readied catalytic frameworks that foster communication, collaboration, a shared vision, and transformative translational research across scientific and non-scientific divides are needed to foster rapid generation of novel solutions to address and ultimately eliminate disparities. To achieve this, we transformed and expanded a community-academic board into a translational science board with members from public, academic and private sectors...

Growing disparities in adult mortality across U.S. states point to the importance of assessing disparities in other domains of health. Here, we estimate state-level differences in disability, and draw on the WHO socio-ecological framework to assess the role of ecological factors in explaining these differences. Our study is based on data from 5.5 million adults aged 25-94 years in the 2010-2014 waves of the American Community Survey. Disability is defined as difficulty with mobility, independent living, self-care, vision, hearing, or cognition...

The most common vision-disrupting complication of cataract surgery is posterior capsule opacification (PCO; secondary cataract). PCO is caused by residual lens cells undergoing one of two very different cell fates: either transdifferentiating into myofibroblasts or maturing into lens fiber cells. Although TGFβ has been strongly implicated in lens cell fibrosis, the factors responsible for the latter process have not been identified. We show here for the first time that TGFβ can induce purified primary lens epithelial cells within the same culture to undergo differentiation into either lens fiber cells or myofibroblasts...

Studies of computer vision or machine vision applications using a light field camera have been increasing in recent years. However, the abilities that the light field camera has are not fully used in these applications. In this paper, we propose a method for direct separation of foreground and background that uses the gradient information and can be used in various applications such as pre-processing. From an optical phenomenon whereby the bundles of rays from the background are flipped, we derive that the disparity sign of the background in the captured three-dimensional scene has the opposite disparity sign of the foreground...

Binocular vision refers to the integration of images in the two eyes for improved visual performance and depth perception. One aspect of binocular vision is the fixation disparity, which is a suboptimal condition in individuals with respect to binocular eye movement control and subsequent neural processing. The objective fixation disparity refers to the vergence angle between the visual axes, which is measured with eye trackers. Subjective fixation disparity is tested with two monocular nonius lines which indicate the physical nonius separation required for perceived alignment...
