#1
Laurie L Ackerman, Daniel H Fulkerson, Andrew Jea, Jodi L Smith
OBJECTIVE Patients with shunts often interact with providers distant from their primary hospital, making it important that the parent(s)/guardian(s) is well versed in the type of shunt implanted and symptoms of malfunction/infection. This is particularly important with magnetic-sensitive programmable valves, as the use of MRI becomes more prevalent. METHODS Over a 6-month period, primary caregivers of 148 consecutive patients who received shunts were prospectively administered questionnaires at clinic visits...

Aim of the Study: This study aims to evaluate the effects three different conditioning agents on the shear bond strength of resin-modified glass ionomers to human dentin. Materials and Methods: One hundred and twenty recently extracted, caries-free premolars and molars will be cleaned of debris and disinfected in a 0.5% solution of sodium hypochlorite and sterile water for 30 min. The occlusal surface of each tooth will be reduced using conventional model trimmer with water to produce the dentin surface...

BACKGROUND: Aerodynamic measures of subglottic air pressure (Ps) and airflow rate (AFR) are used to select behavioral voice therapy versus surgical treatment for voice disorders. However, these measures are usually taken during a series of syllables, which differs from conversational speech. Repeated syllables do not share the variation found in even simple sentences, and patients may use their best rather than typical voice unless specifically instructed otherwise. This study examined the potential differences in estimated Ps and AFR in syllable and sentence production and their effects on a measure of vocal efficiency in normal speakers...

Micromorphology and atomic arrangement on ligament surface of nanoporous metals play a vital role in maintaining the structural stability, adjusting the reaction interface and endowing the functionality. Here we offer an instructive scientific understanding for temperature-induced surface reconstruction and interface structure evolution on ligament of nanoporous copper (NPC) based on systematically experimental observations and theoretical calculations. The results show that with dealloying temperature increasing, ligament surface micromorphology of NPC evolves from smooth to irregularity and to uniformly compressed semisphere, and finally to dispersed single-crystal nanoparticles accompanying with significant changes of interface structure from coherence to semi-coherence and to noncoherence...

The present paper proposes to carefully study and describe the reinforcement mechanisms within a flax stem, which is an exceptional natural model of composite structure. Thanks to accurate microscopic investigations, with both optical and SEM method, we finely depicted the flax stem architecture, which can be view as a composite structure with an outer protection, a unidirectional ply on the periphery and a porous core; each component has a specific function, such as mechanical reinforcement for the unidirectional ply and the porous core...

OBJECTIVE: To design and develop a distance learning (DL) system for the transference of laparoscopic surgery knowledge and skill constructed from off-the-shelf materials and commercially available software. INTRODUCTION: Minimally invasive surgery offers significant benefits over traditional surgical procedures, but adoption rates for many procedures are low. Skill and confidence deficits are two of the culprits. DL combined with simulation training and telementoring may address these issues with scale...

To improve student preparedness for anatomy laboratory dissection, the dental gross anatomy laboratory was transformed using flipped classroom pedagogy. Instead of spending class time explaining the procedures and anatomical structures for each laboratory, students were provided online materials to prepare for laboratory on their own. Eliminating in-class preparation provided the opportunity to end each period with integrative group activities that connected laboratory and lecture material and explored clinical correlations...

Background The UK charity Crisis originated in 1967 as a response to the increasing numbers of homeless people in London, and the first Crisis at Christmas event for rough sleepers was established in 1971. Since then, Crisis has provided numerous services over the Christmas period to the most vulnerable members of society. One of these is the Crisis at Christmas Dental Service (CCDS) which provides emergency and routine dental care from 23-29 of December each year. The charity is entirely dependent on voluntary staffing and industry donations including materials and facilities...

BACKGROUND: As medication non-adherence is a major risk factor for poor post-transplant outcomes, we explored how adherence is assessed, enhanced and integrated across the transplant continuum. AIM: The aim of this study was to study practice patterns regarding pre- and post-transplant medication adherence assessment and interventions in international heart transplant centres. METHODS: We used data from the Building Research Initiative Group: chronic illness management and adherence in heart transplantation (BRIGHT) study, a cross-sectional study conducted in 36 heart transplant centres in 11 countries...

Core/shell nanostructure is versatile for improving or integrating diverse functions, yet it is still limited to homeomorphism with isomorphic core and shell structure. Here, we delineate a selective cation exchange strategy to construct lanthanide core/shell nanoparticles with dissimilar structure. Hexagonal NaLnF4, a typical photon conversion material, was selected to grow cubic CaF2 shell to protect surface exposed Ln3+. Preferential cation exchange between Ca2+ and Na+ triggered the surface hexagonal-to-cubic structure evolution, which remediated the large barrier for heteroepitaxy of monocrystalline CaF2 shell...

Here we show the use of branched peptides (i.e., isopeptides) as the substrates of proteases for generating supramolecular hydrogels via enzymatically clipping the branch off the peptides. As the first report of using a protease to cut branched peptides to enable a molecular process for converting nanostructures, this work illustrates a fundamentally new molecular motif for exploring the applications of protease-instructed self-assembly for soft materials.

INTRODUCTION: Guided bone regeneration (GBR) aims to restore adequate bone volume for the placement of implants in an ideal location. In this article, we analyze different surgical techniques for tissue management during GBR and a modified partial-thickness surgical approach. MATERIALS AND METHODS: In a year's time span, five patients were enrolled in the study: Four women and one man (aged 44-59 years). In four patients, a GBR with simultaneous implant placement was adopted, whereas in another patient, a delayed implant placement was done...

OBJECTIVES: The multi-dose, pre-filled GONAL-f® RFF Redi-ject® (follitropin alfa injection) pen injector was updated following feedback on user experience and pen functionality, as part of a continuous assessment program. Human-factors engineering (HFE) evaluations were conducted to confirm that the updated pen injector could be used by intended users to safely and effectively perform critical tasks identified by the risk-management plan. METHODS: Five rounds of formative evaluation and a simulated-use summative evaluation of the pen injector, instructions for use (IFU), and training video were conducted by HFE specialists or the intended users of the pen injector...
