The Iterative Closest Point (ICP) algorithm is currently one of the most popular methods for rigid registration so that it has become the standard in the Robotics and Computer Vision communities. Many applications take advantage of it to align 2D/3D surfaces due to its popularity and simplicity. Nevertheless, some of its phases present a high computational cost thus rendering impossible some of its applications. In this work, it is proposed an efficient approach for the matching phase of the Iterative Closest Point algorithm...

Many attempts have been made to manufacture multi-contact nerve cuff electrodes that are safe, robust and reliable for long term neuroprosthetic applications. This protocol describes a fabrication technique of a modified cylindrical nerve cuff electrode to meet these criteria. Minimum computer-aided design and manufacturing (CAD and CAM) skills are necessary to consistently produce cuffs with high precision (contact placement 0.51 ± 0.04 mm) and various cuff sizes. The precision in spatially distributing the contacts and the ability to retain a predefined geometry accomplished with this design are two criteria essential to optimize the cuff's interface for selective recording and stimulation...

Electrically conductive metal-organic frameworks (MOFs) are emerging as a subclass of porous materials that can have a transformative effect on electronic and renewable energy devices. Systematic advances in these materials depend critically on the accurate and reproducible characterization of their electrical properties. This is made difficult by the numerous techniques available for electrical measurements and the dependence of metrics on device architecture and numerous external variables. These challenges, common to all types of electronic materials and devices, are especially acute for porous materials, whose high surface area make them even more susceptible to interactions with contaminants in the environment...

BACKGROUND CONTEXT: Lumbar fusion is a common and costly procedure in the United States. Reimbursement for surgical procedures is increasingly tied to care quality and patient safety as part of value-based reimbursement programs. The incidence of adverse quality events among lumbar fusion patients is unknown using the definition of care quality (patient safety indicators [PSI]) utilized by the Centers for Medicare and Medicaid Services (CMS). The association between insurance status and the incidence of PSI is similarly unknown in lumbar fusion patients...

Parkinson's disease (PD) is a neurodegenerative disorder manifesting over time to result in reduced mobility. The impact of PD on spinal fusion has yet to be addressed on a nationwide level. The Nationwide Inpatient Sample (NIS) from 2001 to 2012 was used for analysis. Admissions with spinal fusion of two or more vertebrae (ICD-9 codes=81.62, 81.63 and 81.64) were included and then stratified based on the presence or absence of PD (ICD-9 code=332.0); patients with cancer (ICD-9 codes=140-239) or trauma (ICD-9 codes=805...

Assessment of clinical outcomes such as 30-day mortality following coronary revascularization procedures has historically been used to spur quality improvement programs. Public reporting of risk-adjusted outcomes is already mandated in several states, and proposals to further expand public reporting have been put forward as a means of increasing transparency and potentially incentivizing high quality care. However, for public reporting of outcomes to be considered a useful surrogate of procedural quality of care, several prerequisites must be met...

The application of physiological measures to conservation monitoring has been gaining momentum and, while a suite of physiological traits are available to ascertain disturbance and condition in wildlife populations, glucocorticoids (i.e., GCs; cortisol and corticosterone) are the most heavily employed. The interpretation of GC levels as sensitive indicators of population change necessitates that GCs and metrics of population persistence are linked. However, the relationship between GCs and fitness may be highly context-dependent, changing direction, or significance, depending on the GC measure, fitness metric, life history stage, or other intrinsic and extrinsic contexts considered...

Although there are national recommendations on the function of Acute Medicine Units (AMUs), there is no single agreed best model of care. Additionally, robust data is not always available to determine whether system changes have resulted in improvement. We designed an Excel file to interface with the hospital patient management system to provide real-time data on a number of metrics including AMU length of stay (AMULOS), mortality and readmissions. This demonstrated that improving consultant continuity of care was associated with a reduction in AMULOS and reduced variation in AMULOS...

BACKGROUND AND PURPOSE: Stroke is a leading cause of death in China. Yet the adherence to guideline-recommended ischemic stroke performance metrics in the past decade has been previously shown to be suboptimal. Since then, several nationwide stroke quality management initiatives have been conducted in China. We sought to determine whether adherence had improved since then. METHODS: Data were obtained from the 2 phases of China National Stroke Registries, which included 131 hospitals (12 173 patients with acute ischemic stroke) in China National Stroke Registries phase 1 from 2007 to 2008 versus 219 hospitals (19 604 patients) in China National Stroke Registries phase 2 from 2012 to 2013...

Concerns about the quality of race/ethnicity data collected by hospitals have limited our understanding of healthcare disparities affecting ethnic minorities in the United States. Using data from the New Jersey State Inpatient Databases and the American Community Survey, we calculated age-adjusted AMI hospitalization rates for Asian-American subgroups before (2005-2006) and after (2008-2009) New Jersey hospitals implemented standardized practices to collect more accurate granular race/ethnicity data from patients...

Nutrient enrichment of detritus-based streams increases detrital resource quality for consumers and stimulates breakdown rates of particulate organic carbon (C). The relative importance of dissolved inorganic nitrogen (N) vs. phosphorus (P) for detrital quality and their effects on microbial- vs. detritivore-mediated detrital breakdown are poorly understood. We tested effects of experimental N and P additions on detrital stoichiometry (C:N, C:P) and total and microbial breakdown (i.e., with and without detritivorous shredders, respectively) of five detritus types (four leaf litter species and wood) with different initial C : nutrient content...

BACKGROUND: Neonatal nurse practitioner (NNP) workload is not well studied, and metrics specific to NNP practice are lacking. Factors such as changes in resident duty hours, increasing neonatal intensive care unit admissions, and a shortage of NNPs contribute to NNP workload. Increased workload has been shown to be detrimental to providers and can affect quality of care. PURPOSE: This study quantified NNP workload using a subjective workload metric, the NASA Task Load Index, and a newly developed objective workload metric specific to NNP practice...

The use of the fecal occult blood test (FOBT) for colorectal cancer (CRC) screening is supported by randomized trials demonstrating effectiveness in cancer prevention and widely recommended by guidelines for this purpose. The fecal immunochemical test (FIT), as a direct measure of human hemoglobin in stool has a number of advantages relative to conventional FOBT and is increasingly used relative to that test. This review summarizes current evidence for FIT in colorectal neoplasia detection and the comparative effectiveness of FIT relative to other commonly used CRC screening modalities...

Quantitative MRI (qMRI) provides standardized measures of specific physical parameters that are sensitive to the underlying tissue microstructure and are a first step towards achieving maps of biologically relevant metrics through in vivo histology using MRI. Recently proposed models have described the interdependence of qMRI parameters. Combining such models with the concept of image synthesis points towards a novel approach to synthetic qMRI, in which maps of fundamentally different physical properties are constructed through the use of biophysical models...

BACKGROUND: The biomedical community has now developed a significant number of ontologies. The curation of biomedical ontologies is a complex task and biomedical ontologies evolve rapidly, so new versions are regularly and frequently published in ontology repositories. This has the implication of there being a high number of ontology versions over a short time span. Given this level of activity, ontology designers need to be supported in the effective management of the evolution of biomedical ontologies as the different changes may affect the engineering and quality of the ontology...

Six Sigma and Lean methodologies are effective quality improvement tools in many health care settings. We applied the DMAIC methodology (define, measure, analyze, improve, control) to address deficiencies in our pediatric anesthesia supply chain. We defined supply chain problems by mapping existing processes and soliciting comments from those involved. We used daily distance walked by anesthesia technicians and number of callouts for missing supplies as measurements that we analyzed before and after implementing improvements (anesthesia cart redesign)...
