BACKGROUND: Rising healthcare costs, decreasing reimbursement rates, and changes in American healthcare are forcing physicians to become increasingly business-minded. Both academic and private plastic surgeons can benefit from being educated in business principles. We conducted a systematic review to identify existing business curricula and integrated a business principles curriculum into residency training. METHODS: We anonymously surveyed our department regarding perceived importance of business principles and performed a systematic literature review from 1993-2013 using PubMed and Embase to identify residency training programs that had designed/implemented business curricula...

Murray Valley encephalitis virus (MVEV), a flavivirus belonging to the Japanese encephalitis serogroup, can cause severe clinical manifestations in humans. We report a fatal case of MVEV infection in a young woman who returned from Australia to Canada. The differential diagnosis for travel-associated encephalitis should include MVEV, particularly during outbreak years.

The topical treatment of nail fungal infections has been a focal point of nail research in the past few decades as it offers a much safer and focused alternative to conventional oral therapy. Although the current focus remains on exploring the ways of enhancing permeation through the formidable nail barrier, the understanding of the nail microstructure and composition is far from complete. This article reviews our current understanding of the nail microstructure, composition and diseases. A few of the parameters affecting the nail permeability and potential causes of the recurrence of fungal nail infection are also discussed...

Nasopharyngeal carcinoma (NPC) is an aggressive head and neck cancer characterized by Epstein-Barr virus (EBV) infection and dense lymphocyte infiltration. The scarcity of NPC genomic data hinders the understanding of NPC biology, disease progression and rational therapy design. Here we performed whole-exome sequencing (WES) on 111 micro-dissected EBV-positive NPCs, with 15 cases subjected to further whole-genome sequencing (WGS), to determine its mutational landscape. We identified enrichment for genomic aberrations of multiple negative regulators of the NF-κB pathway, including CYLD, TRAF3, NFKBIA and NLRC5, in a total of 41% of cases...

On the basis of ab-initio calculations, we present a new parametrisation of the Vervisch-Mottet-Goniakowski (VMG) potential [Vervisch et al. Phys. Rev B24, 245411 (2002)] for modelling the oxide-metal interaction. Applying this model to mimic the finite temperature behaviour of large platinum icosahedra deposited on the pristine MgO(100), we find the nanoparticle undergoes two solid-solid transitions. At 650 K the ���squarisation��� of the interface layer, while a full reshaping towards a fcc architecture takes place above 950 K...

In this study, we investigated the effect of intracapsular environment on the survival of anchorage-dependent cells (ADCs) encapsulated in alginate microcapsules with three different core structures, i.e., liquid, semi-liquid and microsphere-encapsulating semi-liquid core, using NIH 3T3 fibroblasts as an ADC model. For the latter, we fabricated poly (ε-caprolactone) microspheres and co-encapsulated them with the cells, to establish cell-substrate interactions in the capsule. The fibroblast cells co-encapsulated with the microspheres exhibited higher survival and growth than those without...

To further inform implementation efforts of a telephone-based physical activity (PA) intervention for breast cancer survivors, we assessed the PA, fatigue, mood, and quality of life of the peer mentors/coaches who delivered the program. The coaches were volunteers with the American Cancer Society's Reach to Recovery program. The coaches (n = 18) delivered the PA intervention to 76 breast cancer survivors in a randomized controlled trial. Coaches completed assessments of PA (self-report), motivational readiness for PA, and standardized measures of psychosocial variables at the start of coaching and at study exit...

MicroCT imaging allows for noninvasive microstructural evaluation of mineralized bone tissue, and is essential in studies of small animal models of bone and joint diseases. Automatic segmentation and evaluation of articular surfaces is challenging. Here, we present a novel method to create knee joint surface models, for the evaluation of PTOA-related joint changes in the rat using an atlas-based diffeomorphic registration to automatically isolate bone from surrounding tissues. As validation, two independent raters manually segment datasets and the resulting segmentations were compared to our novel automatic segmentation process...

: The role played by fever in the outcome of critical illness in children is unclear. This survey of medical and nursing staff in 35 paediatric intensive care units and transport teams in the United Kingdom and Ireland established attitudes towards the management of children with fever. Four hundred sixty-two medical and nursing staff responded to a web-based survey request. Respondents answered eight questions regarding thresholds for temperature control in usual clinical practice, indications for paracetamol use, and readiness to participate in a clinical trial of permissive temperature control...

Importance: Secondary hyperparathyroidism contributes to extraskeletal calcification and is associated with all-cause and cardiovascular mortality. Control is suboptimal in the majority of patients receiving hemodialysis. An intravenously (IV) administered calcimimetic could improve adherence and reduce adverse gastrointestinal effects. Objective: To evaluate the relative efficacy and safety of the IV calcimimetic etelcalcetide and the oral calcimimetic cinacalcet...

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology...

BACKGROUND: S1 screw failure and L5/S1 non-union are issues with long fusions to S1. Improved construct stiffness and S1 screw offloading can help avoid this. S2AI screws have shown to provide similar stiffness to iliac screws when added to L3-S1 constructs. We sought to examine and compare the biomechanical effects on an L2-S1 pedicle screw construct of adding S2AI screws, AxiaLIF, L5-S1 interbody support via transforaminal lumbar interbody fusion (TLIF), and to examine the effect of the addition of cross connectors to each of these constructs...

BACKGROUND: Lateral interbody cages have been proven useful in spinal fusions. Spanning both lateral cortical rims while sparing the Anterior Longitudinal Ligament, the lateral interbody cages restore and maintain disc height while adding stability prior to supplemental fixation. The standard approach for their insertion is by a 90-degree lateral transpsoas method. This is relatively bloodless compared to other techniques although has its limitations, requiring neuro-monitoring and being, at times, very difficult at L4/5 due to iliac crest obstruction or an anterior plexus position...
