For a company to provide high value to its customers, its organization design is critical. As health care transitions to a value-based model, it is critical that spinal care organizations are structured in such a way that they can maximize value to both the patient and the payers. This article will discuss the 3 most common ways that an organization can be structured, and the benefits and problems of each design in spinal care.

Traditionally, the success of a researcher has been judged by the number of publications he or she has published in peer-review, indexed, high impact journals. However, to quantify the impact of research in the wider scientific community, a number of traditional metrics have been used, including Impact Factor, SCImago Journal Rank, Eigenfactor Score, and Article Influence Score. This article attempts to provide a broad overview of the main traditional impact metrics that have been used to assess scholarly output and research impact...

Activation of the interferon (IFN) pathway in response to infection with pathogens results in the induction of IFN-stimulated genes (ISGs) including proinflammatory cytokines, which mount the proper antiviral immune response. However, aberrant expression of these genes is pathogenic to the host. In addition to IFN-induced transcription factors non-IFN-regulated factors contribute to the transcriptional control of ISGs. Here, we show by genome wide expression analysis, siRNA-mediated suppression and Doxycycline-induced overexpression that the cellular transcription factor ZNF395 activates a subset of ISGs including the chemokines CXCL10 and CXCL11 in keratinocytes...

To determine the sensitivity and specificity of HPV16 serology as diagnostic marker for HPV16-driven oropharyngeal squamous cell carcinoma (OPSCC), 214 HNSCC patients from Germany and Italy with fresh-frozen tumor tissues and sera collected before treatment were included in this study. 120 cancer cases were from the oropharynx and 94 were from head and neck cancer regions outside the oropharynx (45 oral cavity, 12 hypopharynx and 35 larynx). Serum antibodies to early (E1, E2, E6 and E7) and late (L1) HPV16 proteins were analyzed by multiplex serology and were compared to tumor HPV RNA status as the gold standard...

The aquatic microbiome is composed of a multi-phylotype community of microbes, ranging from the numerically dominant viruses to the phylogenetically diverse unicellular phytoplankton. They influence key biogeochemical processes and form the base of marine food webs, becoming food for secondary consumers. Due to recent advances in next-generation sequencing, this previously overlooked component of our hydrosphere is starting to reveal its true diversity and biological complexity. We report here that 250 mL of seawater is sufficient to provide a comprehensive description of the microbial diversity in an oceanic environment...

We contend that knowledge about the cellular composition of normal breast epithelium is a prerequisite for understanding proliferative breast disease. Against this background, we used multicolor immunofluorescence to study normal breast epithelium and two types of intraepithelial proliferative breast lesion for expression of the p63, basal keratin K5, glandular keratin K8/18, SMA, ER-alpha, and Ki67. We studied eight normal breast epithelium samples, 12 cases of usual ductal hyperplasia, and 33 cases of low-grade intraepithelial neoplasia (9 flat epithelial atypia, 14 low-grade ductal carcinoma in situ and 10 cases of lobular neoplasia)...

Background Congenital diaphragmatic hernia (CDH) has different clinical presentations depending on whether it is right sided (R-CDH) or left sided (L-CDH). Some have suggested that L-CDH and R-CDH may represent different syndromic phenotypes. This theory would be indirectly supported if different nondiaphragmatic anomalies were associated with laterality. We assessed whether CDH laterality is associated with specific types of nondiaphragmatic anomalies. Methods Cases of CDH were retrospectively identified from five centers, and associated congenital anomalies, prenatal diagnosis, demographics, birth characteristics, and side of the CDH were analyzed...

BACKGROUND AND OBJECTIVE: The number of quality measures has grown dramatically in recent years. This growth has outpaced research characterizing content and impact of these metrics. Our study aimed to identify and classify nationally promoted quality metrics applicable to children, both by type and by content, and to analyze the representation of common pediatric issues among available measures. METHODS: We identified nationally applicable quality measure collections from organizational databases or clearinghouses, federal Web sites, and key informant interviews and then screened each measure for pediatric applicability...

A single subcutaneous (SC) injection of plerixafor results in rapid mobilization of hematopoietic progenitors but fails to mobilize 33% of normal allogeneic sibling donors in one apheresis. We hypothesized that changing the route of administration of plerixafor from SC to intravenous (IV) may overcome the low stem cell yields and allow collection in one day. A phase I trial followed by a phase II efficacy trial was conducted in allogeneic sibling donors. The optimal dose of IV plerixafor was determined to be 0...

Cell-non-autonomous effects of signaling in the nervous system of animals can influence diverse aspects of organismal physiology. We previously showed that phosphorylation of Ser49 of eIF2α in two chemosensory neurons by PEK-1/PERK promotes entry of Caenorhabditis elegans into dauer diapause. Here, we identified and characterized the molecular determinants that confer sensitivity to effects of neuronal eIF2α phosphorylation on development and physiology of C. elegans Isolation and characterization of mutations in eif-2B...

BACKGROUND: Targeted temperature management (TTM) is widely used in critical care settings for conditions including hepatic encephalopathy, hypoxic ischemic encephalopathy, meningitis, myocardial infarction, paediatric cardiac arrest, spinal cord injury, traumatic brain injury, ischemic stroke and sepsis. Furthermore, TTM is a key treatment for patients after out-of-hospital cardiac-arrest (OHCA). However, the optimal cooling method, which is quick, safe and cost-effective still remains controversial...

Optimal postoperative pain control allows for faster recovery, reduced complications, and improved patient satisfaction. Historically, pain management after spine surgery relied heavily on opioid medications. Multimodal regimens were developed to reduce opioid consumption and associated adverse effects. Multimodal approaches used in orthopaedic surgery of the lower extremity, especially joint arthroplasty, have been well described and studies have shown reduced opioid consumption, improved pain and function, and decreased length of stay...

BACKGROUND: To examine whether exposure to general anesthesia for procedures at age ≥40 years is associated with prevalent mild cognitive impairment (MCI) in the elderly. METHODS: A case-control study nested within a population-based cohort. Olmsted County, Minnesota, residents, aged 70-91 years, underwent baseline evaluations that included the Clinical Dementia Rating scale, a neurologic evaluation, and neuropsychologic testing. Individuals identified with MCI (cases) at enrollment were matched 1:2 on age, sex, education, and apolipoprotein genotype with participants who were cognitively normal at the time of the index visit...

Maintenance of specialized epidermis requires signals from the underlying mesenchyme; however, specific pathways involved remain to be identified. By recombining cells from ventral skin of the K14-PTHrP transgenic mice with those from wild-type, we show that transgenic stroma is sufficient to reprogram wild-type keratinocytes into nipple-like epidermis. To identify candidate nipple-specific signaling factors, we compared gene expression signatures of sorted Pdgfrα-positive ventral K14-PTHrP and wild-type fibroblasts, identifying differentially-expressed transcripts of the WNT, HGF, TGFβ, IGF, BMP, FGF and estrogen signaling...

In order to address the dire need for new antibiotics to treat specific strains of drug resistant Gram-negative bacterial infections, a mixed ligand analog of the natural Acinetobacter baumannii selective siderophore, fimsbactin, was coupled to daptomycin, a Gram-positive only antibiotic. The resulting conjugate, 11, has potent activity against multi-drug resistant strains of A. baumannii, both in vitro and in vivo. The study also indicates that conjugation of siderophores to "drugs" that are much larger than the siderophore (iron transport agent) itself facilitates active uptake that circumvents the normal permeability problems in Gram-negative bacteria...

PURPOSE: Pyogenic spondylodiscitis is a rare disease, but its incidence is increasing. Over the last decade, spinal surgery has been modified to become minimally invasive. In degenerative spinal disorders, such minimally invasive surgery (MIS) reduces blood loss, muscular trauma and the hospital stay. However, it is not known whether MIS also confers these benefits to patients with pyogenic spondylodiscitis. This retrospective cohort study compared the safety and efficacy of minimally invasive surgery (MIS) and the conventional open surgical procedure in patients with pyogenic spondylodiscitis...

Prymnesium parvum is a toxin-producing haptophyte that causes harmful algal blooms globally, leading to large-scale fish kills that have severe ecological and economic implications. For the model haptophyte, Emiliania huxleyi, it has been shown that large dsDNA viruses play an important role in regulating blooms and therefore biogeochemical cycling, but much less work has been done looking at viruses that infect P. parvum, or the role that these viruses may play in regulating harmful algal blooms. In this study, we report the isolation and characterization of a lytic nucleo-cytoplasmic large DNA virus (NCLDV) collected from the site of a harmful P...

Effects of elevated pCO₂ on Emiliania huxleyi genetic diversity and the viruses that infect E. huxleyi (EhVs) have been investigated in large volume enclosures in a Norwegian fjord. Triplicate enclosures were bubbled with air enriched with CO₂ to 760 ppmv whilst the other three enclosures were bubbled with air at ambient pCO₂; phytoplankton growth was initiated by the addition of nitrate and phosphate. E. huxleyi was the dominant coccolithophore in all enclosures, but no difference in genetic diversity, based on DGGE analysis using primers specific to the calcium binding protein gene (gpa) were detected in any of the treatments...

Alkyl chains of β-hydroxyesters synthesized by the capping of terminal epoxy groups of diglycidylether of bisphenol A (DGEBA) with palmitic (C16), stearic (C18), or behenic (C22) fatty acids self-assemble forming a crystalline phase. Above a particular concentration solutions of these esters in a variety of solvents led to supramolecular (physical) gels below the crystallization temperature of alkyl chains. A form-stable phase change material (FS-PCM) was obtained by blending the ester derived from behenic acid with eicosane...
