The life course health development (LCHD) model by Halfon et al. conceptualizes health development occurring through person-environment transactions that enable well-being and participation in desired social roles throughout life, areas that have not received adequate attention in healthcare. The aim of this 'perspectives' paper is to apply the six core tenets of the LCHD model and the concept of health development trajectories to individuals with lifelong neurodevelopmental conditions. We share the perspective that modifiable aspects of the environment often restrict health development; we then advocate that children, beginning at a young age, should engage in 'real-world' experiences that prepare them for current and future social roles...

Multi-leaf collimator (MLC) provides an available approach to achieve sophisticated radiotherapy techniques and plays an important role in advanced high quality radiation therapy. Delivery accuracy of radiation therapy mainly depends on the leaf sequence generated by treatment plans and dynamic performance of MLCs. Previous studies have explored the influence of various leaf limited velocities and dose rates on the leaf-positional error. However, there is a lack of research on the influence of different leaf limited accelerations on the delivery accuracy or leaf-positional error...

In spot-scanning particle therapy, inverse treatment planning is usually limited to finding the optimal beam fluences given the beam trajectories and energies. We address the much more challenging problem of jointly optimizing the beam fluences, trajectories and energies. For this purpose, we design a simulated annealing algorithm with an exploration mechanism that balances the conflicting demands of a small mixing time at high temperatures and a reasonable acceptance rate at low temperatures. Numerical experiments substantiate the relevance of our approach and open new horizons to spot-scanning particle therapy...

Motor neurone disease (MND) is a progressive neurological disease causing muscle wasting, gradual paralysis and respiratory failure, with a life expectancy of 2-4 years. In order to better understand how MND is managed in the community, we conducted a qualitative study to explore the challenges healthcare professionals encounter when managing MND in primary healthcare. Based on data from 15 semi-structured interviews with primary healthcare professionals in Norway, we found that MND is viewed as a condition that requires exceptional effort and detailed planning...

Although many researchers have begun to study the area of Cyber Physical Social Sensing (CPSS), few are focused on robotic sensors. We successfully utilize robots in CPSS, and propose a sensor trajectory planning method in this paper. Trajectory planning is a fundamental problem in mobile robotics. However, traditional methods are not suited for robotic sensors, because of their low efficiency, instability, and non-smooth-generated paths. This paper adopts an optimizing function to generate several intermediate points and regress these discrete points to a quintic polynomial which can output a smooth trajectory for the robotic sensor...

OBJECTIVES: Adaptive interaction with the environment requires the ability to predict both human and non-biological motion trajectories. Prior accounts of the neurocognitive basis for prediction of these two motion classes may generally be divided into those that posit that non-biological motion trajectories are predicted using the same motor planning and/or simulation mechanisms used for human actions, and those that posit distinct mechanisms for each. Using brain lesion patients and healthy controls, this study examined critical neural substrates and behavioral correlates of human and non-biological motion prediction...

Overexploitation leads to the ecological extinction of many oceanic species. The depletion of historical abundances of large animals, such as whales and sea turtles, is well known. However, the magnitude of the historical overfishing of exploited invertebrates is unclear. The lack of rigorous baseline data limits the implementation of efficient management and conservation plans in the marine realm. The precious Mediterranean red coral Corallium rubrum has been intensively exploited since antiquity for its use in jewellery...

Spinal screw placement is a challenging task due to small bone corridors and high risk of neurological or vascular complications, benefiting from precision guidance / navigation and quality assurance (QA). Implicit to both guidance and QA is the definition of a surgical plan - i.e., the desired trajectories and device selection for target vertebrae - conventionally requiring time-consuming manual annotations by a skilled surgeon. We propose automation of such planning by deriving the pedicle trajectory and device selection from a patient's preoperative CT or MR...

INTRODUCTION: Early palliative care is not a common practice for patients with COPD. Important barriers are the identification of patients for palliative care and the organization of such care in this patient group. OBJECTIVE: Pulmonologists have a central role in providing good quality palliative care for patients with COPD. To guide future research and develop services, their view on palliative care for these patients was explored. METHODS: A survey study was performed by the members of the Netherlands Association of Physicians for Lung Diseases and Tuberculosis...

OBJECTIVE: Advanced care plans (ACPs) are designed to convey the wishes of patients with regards to their care in the event of incapacity. There are a number of prerequisites for creation of an effective ACP. First, the patient must be aware of their condition, their prognosis, the likely trajectory of the illness, and the potential treatment options available to them. Second, patient input into ACP must be free of any coercive factors. Third, the patient must be able to remain involved in adapting their ACP as their condition evolves...

Revision hip arthroplasty requires comprehensive appreciation of abnormal bony anatomy. Advances in radiology and manufacturing technology have made three-dimensional (3D) representation of osseous anatomy obtainable, which provide visual and tactile feedback. Such life-size 3D models were manufactured from computed tomography scans of three hip joints in two patients. The first patient had undergone multiple previous hip arthroplasties for bilateral hip infections, resulting in right-sided pelvic discontinuity and a severe left-sided posterosuperior acetabular deficiency...

We introduce a novel optimization-based motion planner, Stochastic Extended LQR (SELQR), which computes a trajectory and associated linear control policy with the objective of minimizing the expected value of a user-defined cost function. SELQR applies to robotic systems that have stochastic non-linear dynamics with motion uncertainty modeled by Gaussian distributions that can be state- and control-dependent. In each iteration, SELQR uses a combination of forward and backward value iteration to estimate the cost-to-come and the cost-to-go for each state along a trajectory...
