Using Simulation to Improve Systems
Attempts to understand and improve health care delivery often focus on the characteristics of the patient and the characteristics of the health care providers, but larger systems surround and integrate with patients and providers. Components of health care delivery systems can support or interfere with efforts to provide optimal health care. Simulation in situ, involving real teams participating in simulations in real care settings, can be used to identify latent safety threats and improve the work environment while simultaneously supporting participant learning. Thoughtful planning and skilled debriefing are essential.

Total lower lip and chin reconstruction with radial forearm free flap: A novel approach
The management of large chin and lower lip defects is challenging due to this facial subunit's tremendous functional and aesthetic importance. Specific methods for total lower lip and mentum reconstruction are not well chronicled. Aesthetic and functional goals of this reconstruction include restoration of oral competence by maintaining lower lip height, vermilion reestablishment, color-matched skin introduction to the chin, sensation restoration, and ideally restoration of dynamic activity to the lower lip.

Use of yeast ( Pichia kudriavzevii ) as a novel feed additive to ameliorate the effects of aflatoxin B 1 on broiler chicken performance
Abstract
The aim of this study was to evaluate the efficacy of autochthonous Pichia kudriavzevii as a novel bioadsorbent for aflatoxin B1 (AFB1). The selection of this yeast was based on the AFB1 adsorption capacity previously demonstrated in vitro (Magnoli et al. 2016). One-day-old Cobb broilers (n = 160) were randomly assigned to four dietary treatments (T1: basal diet (B); T2: B + 0.1% yeast; T3: B + AFB1, 100 μg/kg; T4: B + 0.1% yeast + AFB1, 100 μg/kg). Performance parameters (average daily weight gain body, average daily consumption, feed conversion ratio, carcass weight, and dead weight), biochemical parameters (albumin, globulin, and albumin/globulin), liver pathological changes, and AFB1 residual levels in the liver and excreta were evaluated. Significant differences (P < 0.05) in performance parameters were observed among treatments and controls: T3 group showed the lowest average daily body weight gain value while in T4 group, the value of this parameter increased significantly (P < 0.05). T3 and T4 groups showed the lowest and highest values for average daily feed consumption, respectively. The feed conversion ratio (FC) showed no significant differences among treatments. T3 group showed the lowest dead weight and carcass weight compared with T1 group. The biochemical parameters showed no significant differences among treatments. T3 group showed macroscopic and microscopic liver changes compared to the control. Aflatoxin B1 levels (μg/g) were detected in broiler livers and showed significant differences among treatments (P < 0.05). In conclusion, native P. kudriavzevii incorporation (0.1%) in broiler diets containing AFB1 was shown to be effective in ameliorating the adverse effects of AFB1 on production.

Biphasic synovial sarcoma of the epiglottis: Case report and literature review
Source:Auris Nasus Larynx
Author(s): Marlene C. Wigand, Thomas K. Hoffmann, Thomas F.E. Barth, Johannes Veit
Synovial sarcomas are rare malignant tumors supposed to arise from pluripotent mesenchymal stem cells predominantly affecting the deep soft tissue of the lower and upper extremities in young adults. The occurrence of this tumor entity in the head and neck is very uncommon and hence, timely diagnosis and treatment of synovial sarcoma in this region remain a challenge.We describe the clinical and molecular pathological features of a biphasic synovial sarcoma of the epiglottis, a site where the primary manifestation of this tumor entity has not been documented to date. With this background the existing literature is being reviewed. Whilst wide excision of synovial sarcoma is considered as the primary mainstay of therapy, (neo)adjuvant treatment strategies have been proposed to increase local control and prolong disease-free survival.

Prognostic score in patients with recurrent or metastatic carcinoma of the head and neck treated with cetuximab and chemotherapy
by Teresa Magnes, Thomas Melchardt, Lukas Weiss, Christof Mittermair, Daniel Neureiter, Eckhard Klieser, Simon Gampenrieder, Gerhard Moser, Alexander Gaggl, Richard Greil, Alexander Egle
Despite modern treatment approaches, survival of patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN) remains low and it is difficult to identify patients who derive optimal benefit from treatment. We therefore analyzed which commonly available laboratory and clinical parameters may help improve the prognostication in this patient group. This retrospective monocenter analysis includes 128 patients with recurrent or metastatic SCCHN treated with cetuximab alone or in combination with polychemotherapy as first line therapy. Factors with independent prognostic power in the multivariate analysis were used to build up a score separating patient groups with different survival. Patients had a median age of 61 years and 103 patients were treated with polychemotherapy plus cetuximab. An ECOG score above 1, high CRP and leukocyte levels, less intensive treatment and a time below 12 months from primary diagnosis to relapse remained as independent negative prognostic factors in multivariate analysis. Patients with 0 to 1 risk factors had a median OS of 13.6 months compared to a median OS of less than one month for patients 4 to 5 risk factors (phttp://ift.tt/2u0rT2o
Assessment of circulating copy number variant detection for cancer screening
by Bhuvan Molparia, Eshaan Nichani, Ali Torkamani
Current high-sensitivity cancer screening methods, largely utilizing correlative biomarkers, suffer from false positive rates that lead to unnecessary medical procedures and debatable public health benefit overall. Detection of circulating tumor DNA (ctDNA), a causal biomarker, has the potential to revolutionize cancer screening. Thus far, the majority of ctDNA studies have focused on detection of tumor-specific point mutations after cancer diagnosis for the purpose of post-treatment surveillance. However, ctDNA point mutation detection methods developed to date likely lack either the scope or analytical sensitivity necessary to be useful for cancer screening, due to the low (http://ift.tt/2tVbNq7

Autoimmunity and allergy control in adults submitted to complete thymectomy early in infancy
by Susana L. Silva, Adriana Albuquerque, Andreia J. Amaral, Quan-Zhen Li, Catarina Mota, Rémi Cheynier, Rui M. M. Victorino, M. Conceição Pereira-Santos, Ana E. Sousa
The contribution of the decline in thymic activity for the emergence of autoimmunity is still debatable. Immune-competent adults submitted to complete thymectomy early in life provide a unique model to address this question. We applied here strict criteria to identify adults lacking thymic activity based on sjTREC levels, to exclude thymic rebound and/or ectopic thymuses. In agreement, they featured severe naïve CD4 T-cell depletion and contraction of T-cell receptor diversity. Notwithstanding this, there was neither increased incidence of autoimmune disease in comparison with age-matched controls nor significant changes in their IgG/IgA/IgM/IgE autoreactivity profiles, as assessed through extensive arrays. We reasoned that the observed relative preservation of the regulatory T-cell compartment, including maintenance of naïve regulatory CD4 T-cells, may contribute to limit the emergence of autoimmunity upon thymectomy. Our findings have implications in other clinical settings with impaired thymic activity, and are particularly relevant to studies of autoimmunity in ageing.http://ift.tt/2u08UFd

The microbiota and autoimmunity: Their role in thyroid autoimmune diseases
Source:Clinical Immunology
Author(s): Hedda L. Köhling, Sue F. Plummer, Julian R. Marchesi, Kelly S. Davidge, Marian Ludgate
Since the 1970s, the role of infectious diseases in the pathogenesis of Graves' disease (GD) has been an object of intensive research. The last decade has witnessed many studies on Yersinia enterocolitica, Helicobacter pylori and other bacterial organisms and their potential impact on GD. Retrospective, prospective and molecular binding studies have been performed with contrary outcomes. Until now it is not clear whether bacterial infections can trigger autoimmune thyroid disease. Common risk factors for GD (gender, smoking, stress, and pregnancy) reveal profound changes in the bacterial communities of the gut compared to that of healthy controls but a pathogenetic link between GD and dysbiosis has not yet been fully elucidated. Conventional bacterial culture, in vitro models, next generation and high-throughput DNA sequencing are applicable methods to assess the impact of bacteria in disease onset and development. Further studies on the involvement of bacteria in GD are needed and may contribute to the understanding of pathogenetic processes. This review will examine available evidence on the subject.

When Empowering Leadership Fosters Creative Performance: the Role of Problem Solving Demands and Creative Personality
The purpose of this paper is to investigate the circumstances under which empowering leadership fosters creative performance. Arguments were developed for a three-way interaction of empowering leadership, problem solving demands and creative personality in this linkage. These arguments resulted in competing hypotheses from a fit and a compensation perspective. The results from a survey of 213 employees of a Flemish large industrial organization were used. We found that less creative employees in jobs with high problem solving demands particularly benefit from empowering leadership. This paper adds to a more complex understanding of the effectiveness of empowering leadership by highlighting the relevance of the simultaneous interplay of contextual and personal factors.

Evaluating business process maturity models
Maturity models have become important aids to support process improvement. However, researchers have frequently criticized the many business process maturity models (BPMMs) for differing in quality, which creates a demand for comparing and evaluating these models. This paper describes a well-founded, ranked, and weighted set of critical criteria for BPMMs that are most important to prospective users. The paper also demonstrates how this set can serve as a standard or guideline for designing BPMMs. In evaluating the used sample of BPMMs against the set of criteria, we reveal gaps and shortcomings of current BPMMs, make suggestions for raising the quality of BPMMs, and highlight future research avenues.

A World without Hunger: Organic or GM Crops?
It has been estimated that the world population will increase to 9.2 billion by 2050; supplying the growing population with food will require a significant increase in agricultural production. A number of agricultural and ecological scientists believe that a large-scale shift to organic farming (OF) would not only increase the world's food supply, but might be the only way to eradicate hunger sustainably. Nevertheless, OF has recently come under new scrutiny, not just from critics who fear that a large-scale shift in this direction would cause billions to starve but also from farmers and development agencies who question whether such a shift could improve food security. Meanwhile, the use of genetically modified (GM) crops is growing around the world, leading to possible opportunities to combat food insecurity and hunger. However, the development of GM crops has been a matter of considerable interest and worldwide public controversy. So far, no one has comprehensively analyzed whether a widespread shift to OF or GM would be the sole solution for both food security and safety. Using a literature review from databases of peer-reviewed scientific publications, books, and official publications, this study aims to address this issue. Results indicate that OF and GM, to different extents, are able to ensure food security and safety. In developed countries, given that there are relatively few farmers and that their productivity, even without GMOs, is relatively high, OF could be more a viable option. However, OF is significantly less efficient in land-use terms and may lead to more land being used for agriculture due to its lower yield. In developing countries, where many small-scale farmers have low agricultural productivity and limited access to agricultural technologies and information, an approach with both GM and OF might be a more realistic approach to ensure food security and safety.

A comparative study on basophil activation test, histamine release assay and passive sensitization histamine release assay in the diagnosis of peanut allergy
Abstract
Background
Allergy can be diagnosed using basophil tests. Several methods measuring basophil activation are available. This study aimed at comparing basophil activation test (BAT), histamine release assay (HR) and passive sensitization histamine release assay (passive HR) in the diagnosis of peanut allergy.
Methods
BAT, HR, and passive HR were performed on eleven peanut allergic and fourteen non-allergic subjects. Blood was incubated with peanut extract or anti-IgE and tests performed as follows: BAT - CD63-upregulation assessed by flow cytometry; HR - released histamine quantified by a glass fiber-based fluorometric method; Passive HR - IgE-stripped donor basophils were incubated with participants' serum and histamine release quantified as HR.
Results
CDsens, a measure of basophil allergen sensitivity, was significantly higher for BAT (80.1 ± 17.4) compared to HR (23.4 ± 10.31) and passive HR (11.1 ± 2.0). BAT, HR, and passive HR had a clinical sensitivity of 100%, 100%, and 82%, and specificity of 100%, 100%, and 100%, respectively when excluding inconclusive results. BAT identified 11 of 11 allergic patients, HR 10 and passive HR 9. Likewise, BAT recognized 12 of 14 non-allergic subjects, HR 10 and passive HR 13. However, the tests' diagnostic performances were not statistically different. Interestingly, non-releasers in HR but not in BAT had lower basophil count compared to releasers (249 vs. 630 counts/min).
Conclusion
BAT displayed a significant higher CDsens compared to HR and passive HR. The basophil tests' diagnostic performances were not significantly different. Still, BAT could diagnose subjects with low basophil number in contrast to HR.

BSACI guideline for the diagnosis and management of allergic and non-allergic rhinitis (Revised Edition 2017; First edition 2007)
Abstract
This is an updated guideline for the diagnosis and management of allergic and non-allergic rhinitis, first published in 2007. It was produced by the Standards of Care Committee of the British Society of Allergy and Clinical Immunology, using accredited methods. Allergic rhinitis is common and affects 10–15% of children and 26% of adults in the UK, it affects quality of life, school and work attendance, and is a risk factor for development of asthma. Allergic rhinitis is diagnosed by history and examination, supported by specific allergy tests. Topical nasal corticosteroids are the treatment of choice for moderate to severe disease. Combination therapy with intranasal corticosteroid plus intranasal antihistamine is more effective than either alone and provides second line treatment for those with rhinitis poorly controlled on monotherapy. Immunotherapy is highly effective when the specific allergen is the responsible driver for the symptoms. Treatment of rhinitis is associated with benefits for asthma. Non-allergic rhinitis also is a risk factor for the development of asthma and may be eosinophilic and steroid-responsive or neurogenic and non- inflammatory. Non-allergic rhinitis may be a presenting complaint for systemic disorders such as granulomatous or eosinophilic polyangiitis, and sarcoidoisis. Infective rhinitis can be caused by viruses, and less commonly by bacteria, fungi and protozoa.

Silver Alginate Hydrogel Micro- and Nanocontainers for Theranostics: Synthesis, Encapsulation, Remote Release, and Detection
We have designed multifunctional silver alginate hydrogel microcontainers referred to as loaded microcapsules with different sizes by assembling them via a template assisted approach using natural, highly porous calcium carbonate cores. Sodium alginate was immobilized into the pores of calcium carbonate particles of different sizes followed by cross-linking via addition of silver ions, which had a dual purpose: on one hand, the were used as a cross-linking agent, albeit in the monovalent form, while on the other hand they have led to formation of silver nanoparticles. Monovalent silver ions, an unusual cross-linking agent, improve the sensitivity to ultrasound, lead to homogeneous distribution of silver nanoparticles. Silver nanoparticles appeared on the shell of the alginate microcapsules in the twin-structure as determined by transmission electron microscopy. Remote release of a payload from alginate containers by ultrasound was found to strongly depend on the particle size. The possibility to use such particles as a platform for label-free molecule detection based on the surface enhanced Raman scattering was demonstrated. Cytotoxicity and cell uptake studies conducted in this work have revealed that microcontainers exhibit nonessential level of toxicity with an efficient uptake of cells. The above-described functionalities constitute building blocks of a theranostic system, where detection and remote release can be achieved with the same carrier.

Service provider DevOps for large scale modern network services
Network service providers are facing challenges for deploying new services mainly due to the growing complexity of software architecture and development process. Moreover, the recent architectural innovation of network systems such as Network Function Virtualization (NFV), Software-defined Networking (SDN), and Cloud computing increases the development and operation complexity yet again. One of the emerging solutions to this problem is a novel software development concept, namely DevOps, that is widely employed by major Internet software companies. Although the goals of DevOps in data centers are well-suited for the demands of agile service creation, additional requirements specific to the virtualized and software-defined network environment are important to be addressed from the perspective of modern network carriers. In this paper, we thoroughly debate DevOps requirements for developing a modern service creation platform by taking EU FP7 project UNIFY as a reference architecture and suggest the corresponding extensions of UNIFY interfaces that meet the discovered requirements.

Taking Advertising Literacy to a Higher Level: An Exploratory Multilevel Analysis of Children's Advertising Literacy
As few studies focus on how children's coping with advertising is affected by their environment, the present study uses multilevel analysis to explore the role of both primary (i.e. parents) and secondary socializing agents (i.e. classmates, teachers) in children's advertising literacy. The results show that children's cognitive advertising literacy and attitudes toward advertising are to a large extent determined by class-level processes. Their moral advertising literacy is a more individual matter, yet greatly influenced by children's teachers – though in a remarkable manner. Parents do not seem to have much of an impact, except through socioeconomic factors such as educational background.

Evaluation of performance models for farm-specific optimization of pig production
Farm-specific optimization of pig production can be supported with a production function mechanistically derived from dynamic growth and feed intake information, hereafter called performance curves. Production theoretical optimization requires, first, an accurate description of underlying processes and, second, possibilities for calibrations with available on-farm data. The objective is to evaluate accuracy and calibration requirements of seven models: the Gompertz, Monomolecular, Richards and Generalized Michaelis-Menten (GMM) model for growth and the cumulative feed intake and weight (CFIW), Bridges and Giesen models for both growth and feed intake. Evaluation is done with data from four trials with four sexes of a Pietrain x hybrid sow cross: boars, barrows, gilts and GnRH-vaccinated boars. Accuracy was evaluated with Root Mean Squared Errors (RMSE) of predictions versus observations and F-tests for differences in goodness-of-fit to discriminate between models. Calibration possibilities were evaluated through fitting the models through limited data. The Giesen, Bridges and GMM model, describing sigmoidal growth patterns, showed the highest accuracy. In terms of calibration possibilities, the Bridges model slightly outperformed the other. The Giesen model is accurate for describing feed intake of boars, barrows, gilts. GnRH-vaccinated animals showed unstable variance with increasing age of the animal, which could only partially been solved with extensions to the Bridges and Giesen model. The research showed that dynamic growth and feed intake curves can be reasonably estimated from limited on-farm collectable data and generic functional forms, and as such account for farm specificity in production-theoretical economic optimization.

From persuasive messages to tactics: Exploring children’s knowledge and judgment of new advertising formats
Despite that contemporary advertising is decreasingly about persuading children through persuasive messages and increasingly about influencing them through implicit tactics, little attention has been given to how children may cope with advertising by understanding and evaluating the new advertising tactics. Drawing on 12 focus groups entailing 60 European children of ages 9-11, this article investigates children's advertising literacy by exploring their knowledge and judgments (and according reasoning strategies) of the new advertising formats. In particular, insight is provided into children's critical reflection on the tactics of brand integration, interactivity and personalization in the advertising formats brand placement, advergames and retargeted pre-roll video ads on social media. It is shown that while children not spontaneously do so, they appear to have the ability to understand these tactics and form judgments about their (moral) appropriateness, thereby considering a wide range of societal actors.

Effects of low to moderate levels of deoxynivalenol on feed and water intake, weight gain, and slaughtering traits of broiler chickens
Abstract
The aim of the study was to evaluate the effects of low to moderate oral exposure to the Fusarium toxin deoxynivalenol (DON; derived from culture material) on performance, water intake, and carcass parameters of broilers during early and late developmental phases. A total of 160 Ross 308 broilers were randomly allocated to four different feeding groups (n = 40/group) including 0 (control), 2.5, 5, and 10 mg DON/kg wheat-soybean meal-based feed. Three consecutive replicates of the experiment were performed. Half of the broilers were slaughtered in week 3 of the trial whereas the other half were slaughtered in week 5. Dry matter intake (DMI) and water intake (WI) were recorded on a daily basis and the body weight (BW) and BW gain (BWG) were determined weekly. The following carcass traits were recorded and calculated in absolute and relative data: dressed carcass weight, breast muscle weight, leg weight, and liver weight. Data showed that BW (P < 0.001), BWG (P = 0.005), and DMI (P < 0.001) were reduced by DON-feeding during the entire feeding period. The ratio of DMI to body weight gain (DMI/BWG) was not affected by the treatment. However, the ratio of water to DMI (WI/DMI) increased in DON-treated birds (P = 0.021). Contrast analysis showed that DON tendentially reduced slaughter weight (P = 0.082) and decreased leg yield (P = 0.037) in DON-fed chickens in week 5 of the experiment. Liver organ weight decreased in the 3-week-old DON-fed broilers compared to that in the control-fed birds (P = 0.037). In conclusion, the study suggests that DMI and BW were negatively affected under the experimental conditions at DON levels lower than the current guidance value in the European Union of 5 mg/kg feed. The study also indicates that broilers fed on low to moderate level DON-contaminated diets showed increased WI/DMI ratio which might have negative influence on wet litter syndrome.

Trapping in proton irradiated p(+)-n-n(+) silicon sensors at fluences anticipated at the HL-LHC outer tracker
The degradation of signal in silicon sensors is studied under conditions expected at the CERN High-Luminosity LHC. 200 mu m thick n-type silicon sensors are irradiated with protons of different energies to fluences of up to 3.10(15) neq/cm(2). Pulsed red laser light with a wavelength of 672 nm is used to generate electron-hole pairs in the sensors. The induced signals are used to determine the charge collection efficiencies separately for electrons and holes drifting through the sensor. The effective trapping rates are extracted by comparing the results to simulation. The electric field is simulated using Synopsys device simulation assuming two effective defects. The generation and drift of charge carriers are simulated in an independent simulation based on PixelAV. The effective trapping rates are determined from the measured charge collection efficiencies and the simulated and measured time-resolved current pulses are compared. The effective trapping rates determined for both electrons and holes are about 50% smaller than those obtained using standard extrapolations of studies at low fluences and suggest an improved tracker performance over initial expectations.

Risk of cutaneous T-cell lymphoma in patients with chronic lymphocytic leukemia and other subtypes of non-Hodgkin lymphoma
Abstract
Background
Second hematologic cancers in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) are well documented and include Hodgkin lymphoma, therapy-related acute myeloid leukemia/myelodysplastic syndromes, and transformation to diffuse large B-cell lymphoma. Although cutaneous T-cell lymphoma (CTCL) has been reported in patients with CLL, the incidence and comparison to expected rates are unknown. We evaluated the incidence of CTCL among patients with CLL or other non-Hodgkin lymphoma (NHL) subtypes using data from the Surveillance, Epidemiology, and End Results (SEER) Program.
Methods
We searched the SEER 13 registries for patients with a diagnosis of CLL and NHL between 1992 and 2008. Among patients identified, we evaluated the incidence of CTCL.
Results
Among 31,286 patients with CLL, the incidence of CTCL was not significantly higher in men than women: 104.2 (95% CI, 50.0–191.8) and 28.1 (95% CI, 3.4–101.3) per 1,000,000 person-years, respectively (P = 0.06). Among 97,691 patients with NHL, the incidence of CTCL was similar in men and women (97.9 [95% CI, 62.0–146.9] and 92.0 [95% CI, 56.2–142.1] per 1,000,000 person-years, respectively; P = 0.84). The incidence of CTCL among males with CLL (standardized incidence ratio [SIR], 3.0 [95% CI, 1.4–5.5]), males with NHL (SIR, 3.7 [95% CI, 2.3–5.5]), and females with NHL (SIR, 5.9 [95% CI, 3.6–9.1]) was significantly higher than expected in the general population (all P < 0.001).
Conclusion
The risk of CTCL is greater in men with CLL than in the general population. In patients with NHL, both men and women are at greater risk for CTCL than in the general population.

When is the Fukui function not normalized? : the danger of inconsistent energy interpolation models in density functional theory
When one defines the energy of a molecule with a noninteger number of electrons by interpolation of the energy values for integer-charged states, the interpolated electron density, Fukui function, and higher-order derivatives of the density are generally not normalized correctly. The necessary and sufficient condition for consistent energy interpolation models is that the corresponding interpolated electron density is correctly normalized to the number of electrons. A necessary, but not sufficient, condition for correct normalization is that the energy interpolant be a linear function of the reference energies. Consistent with this general rule, polynomial interpolation models and, in particular, the quadratic E vs N model popularized by Parr and Pearson, do give normalized densities and density derivatives. Interestingly, an interpolation model based on the square root of the electron number also satisfies the normalization constraints. We also derive consistent least-norm interpolation models. In contrast to these models, the popular rational and exponential forms for E vs N do not give normalized electron densities and density derivatives.

Adrenal incidentaloma in a patient with HIV/AIDS
Abstract
Human immunodeficiency virus (HIV) is well known to be associated with various neoplasms and opportunistic infections. Kaposi sarcoma (KS), associated with human herpes virus 8 (HHV8) infection, is the most common tumour in HIV positive patients and is also an acquired immune deficiency syndrome (AIDS) defining illness. Cutaneous manifestations are the most common presenting symptom; however, visceral involvement is also recognized. We present the case of a 55-year-old male who was diagnosed with AIDS-related KS, who was referred to our surgical unit with an indeterminate left adrenal lesion. He subsequently started antiretroviral therapy and given the indeterminate nature of his adrenal lesion, we performed a laparoscopic left adrenalectomy, with KS of the adrenal gland confirmed on histologyhttp://ift.tt/2tYQDbk
Eccrine angiokeratomatous hamartoma: case report of a 1.5-year girl
Abstract
Eccrine angiokeratomatous hamartoma is a rare newly defined vascular lesion of the skin, the first case of which was reported in 2006 (Kanitakis J, Ly A, Claudy A. Eccrine angiokeratomatous hamartoma: a new variant of eccrine hamartoma with angiokeratoma. J Am Acad Dermatol 2006; 55: S104–6). On web Literature Search, Only three previously documented cases of the lesions were found. A 1.5-year-old female child presented with a painless lesion on her right leg since birth which has been gradually increasing in size and recently developed central ulceration. Histological examination of the excised lesion confirmed the diagnosis. This is the first of the cases to be reported in paediatric age-group (<2 years)http://ift.tt/2tYYZzP
Myomectomies for massive hemoperitoneum from spontaneous bleeding of a uterine myoma
Abstract
Massive hemoperitoneum from spontaneous bleeding of uterine myoma is an extremely rare condition, that needs urgent surgical exploration. We report a 40-year-old woman, admitted for acute onset of abdominal pain. Physical examination revealed hypovolemic shock. The hemoglobin level was of 5 g/dL. Ultrasonography revealed hemoperitoneum. Emergency surgical exploration was planned. There was hemoperitoneum of 3 L, uterine myomas with multiple subserous myomas, bleeding from superficial ruptured varice overlying the most largest subserous myoma, which measured 15 cm. Glove adapted as a tourniquet, was applied at the base of the uterus, and myomectomies were performed with removal of around twenty myomas. The postoperative course was uneventful. Myomectomies can be safely and effectively performed by using a tourniquet, for massive hemoperitoneum with precarious hemodynamic status due to subserous myoma bleeding, despite the number and the size of myomas.http://ift.tt/2tZ2M02
Treatment, short-term outcomes, and costs associated with larynx cancer care in commercially insured patients
Objectives/Hypothesis
To examine associations between treatment, complications, and costs in patients with laryngeal cancer.
Study Design
Retrospective cross-sectional analysis of MarketScan Commercial Claim and Encounters data.
Methods
We evaluated 10,969 patients diagnosed with laryngeal cancer from 2010 to 2012 using cross-tabulations and multivariate regression.
Results
Chemoradiation was significantly associated with supraglottic tumors (relative risk ratio [RRR] = 5.9 [4.4–7.8]), pretreatment gastrostomy (RRR = 4.0 [2.7–6.1]), and alcohol abuse (RRR = 0.5 [0.3–0.9]). Treatment-related complications occurred in 23% of patients, with medical complications in 22% and surgical complications in 7%. Chemoradiation (odds ratio [OR] = 3.7 [2.6–5.2]), major surgical procedures (OR = 4.9 [3.5–6.8]), reconstruction (OR = 7.7 (4.1–14.7)], and advanced comorbidity (OR = 9.7 [5.7–16.5] were associated with acute complications. Recurrent/persistent disease occurred in 23% of patients and was associated with high-volume care (OR = 1.4 [1.1–1.8]). Salvage surgery was performed in 46% of patients with recurrent/persistent disease and was less likely for supraglottic disease (OR = 0.5 [0.4–0.8]) and after chemoradiation (OR = 0.4 [0.2–0.6]). Initial treatment and 1-year overall costs for chemoradiation were higher than all other treatment categories, after controlling for all other variables including complications and salvage. High-volume care was associated with significantly lower costs of care for surgical patients but was not associated with differences in costs of care for nonoperative treatment.
Conclusions
In commercially insured patients <65 years old with laryngeal cancer, chemoradiation was associated with increased costs, an increased likelihood of treatment-related medical complications, and a reduced likelihood of surgical salvage. Higher-volume surgical care was associated with lower initial treatment and 1-year costs of care. These data have implications for discussions of value and quality in an era of healthcare reform.

Central hypothyroidism in Miniature Schnauzers
Background: Primary hypothyroidism is a common endocrinopathy in dogs. In contrast, central hypothyroidism is rare in this species. Objectives: The objective of this article is to describe the occurrence and clinical presentation of central hypothyroidism in Miniature Schnauzers. Additionally, the possible role of the thyroid-stimulating hormone (TSH)-releasing hormone receptor (TRHR) gene and the TSH beta (TSHB) gene was investigated. Animals: Miniature Schnauzers with proven central hypothyroidism, based on scintigraphy, and the results of a 3-day-TSH-stimulation test, or a TSH-releasing hormone (TRH)-stimulation test or both, presented to the Department of Clinical Sciences of Companion Animals at Utrecht University or the Department of Medicine and Clinical Biology of Small Animals at Ghent University from 2008 to 2012. Methods: Retrospective study. Pituitary function tests, thyroid scintigraphy, and computed tomography (CT) of the pituitary area were performed. Gene fragments of affected dogs and controls were amplified by polymerase chain reaction (PCR). Subsequently, the deoxyribonucleic acid (DNA) sequences of the products were analyzed. Results: Central hypothyroidism was diagnosed in 7 Miniature Schnauzers. Three dogs had disproportionate dwarfism and at least one of them had a combined deficiency of TSH and prolactin. No disease-causing mutations were found in the TSHB gene and the exons of the TRHR gene of these Schnauzers. Conclusions and clinical importance: Central hypothyroidism could be underdiagnosed in Miniature Schnauzers with hypothyroidism, especially in those of normal stature. The fact that this rare disorder occurred in 7 dogs from the same breed suggests that central hypothyroidism could have a genetic background in Miniature Schnauzers.

The Belgian Co-operative Model: Elements of Succes and Failure
Europe has a long tradition of consumer co-operatives and historians have mainly focused on the success stories, as they often tend to do. This chapter assesses initiatives that proved successful as well as unsuccessful in the Dutch speaking part of Belgium in the period 1875-1914. It analyses the Ghent Vooruit co-operative, one of the most outstanding examples of a successful project, even by European standards , while contrasting it with De Werker(The Worker), an Antwerp co-operative which hardly managed to survive, and De Zon(The Sun) in the provincial town of Zele. The latter went bankrupt in 1903. Are there any lessons to be learned from these examples? And are they equally valid in other cases? In other words, is it possible to suggest some factors which contribute to the success or failure of consumer co-operatives in general?

Standardized exercise tests in horses : current situation and future perspectives
The purpose of this literature review is to clarify how exercise capacity can be measured in horses and which standardized exercise tests (SETs) exist. In this review, the measurement of the exercise capacity of horses is discussed and the standardized exercise tests (SET) are described. Two main types of SETs are used. Laboratory or treadmill tests are easy to standardize and provide more options to use all kinds of measuring devices, since the horse stays on the treadmill. On the other hand, field tests are conducted under the natural conditions associated with the specific sports discipline, and are easier to implement in the training schedule. However, field tests encompass interfering variables, such as weather conditions, ground surface conditions and the rider or jockey. Several variables are measured in order to calculate the fitness level which may be expressed by different parameters, such as V200 (speed at a heart rate of 200 beats per minute), V1a4 (speed at a blood lactic acid level of 4 mmol/L) and VO2max (maximum oxygen uptake).

Diagnosis and ultrasound-guided retrieval of a vaginal foreign body in a dog and a cat
In this case report, the diagnosis and ultrasound-guided retrieval of an intravaginal grass awn in a dog and a cat are described. The dog was presented with chronic vaginal discharge for over two years. The cat was presented for acute lethargy and bloody vaginal discharge and a two-week history of a perivulvar leakage. Ultrasonographic diagnosis included the visualization of a linear, hyperechoic and spindle-shaped structure and mild thickness of the vagina. The grass awns were successfully retrieved non-invasively, under general anesthesia using ultrasound-guided Hartmann forceps inserted into the vagina. Ultrasound-guided grass awn retrieval from the vagina appears to be a safe and inexpensive procedure.

Anesthesia for minimally invasive neurosurgery.
Purpose of review: With an ultimate aim of improving patients overall outcome and satisfaction, minimally invasive surgical approach is becoming more of a norm. The related anesthetic evidence has not expanded at the same rate as surgical and technological advancement. This article reviews the recent evidence on anesthesia and perioperative concerns for patients undergoing minimally invasive neurosurgery. Recent findings: Minimally invasive cranial and spinal surgeries have been made possible only by vast technological development. Points of surgical interest can be precisely located with the help of stereotaxy and neuronavigation and special endoscopes which decrease the tissue trauma. The principles of neuroanethesia remain the same, but few concerns are specific for each technique. Dexmedetomidine has a favorable profile for procedures carried out under sedation technique. As the new surgical techniques are coming up, lesser known anesthetic concerns may also come into light. Summary: Over the last year, little new information has been added to existing literature regarding anesthesia for minimally invasive neurosurgeries. Neuroanesthesia goals remain the same and less invasive surgical techniques do not translate into safe anesthesia. Specific concerns for each procedure should be taken into consideration.

Criteria for Intensive Care admission and monitoring after elective craniotomy.
Purpose of review: The current article revises the recent evidence on ICU admission criteria and postoperative neuromonitoring for patients undergoing elective craniotomy. Recent findings: Only a small proportion of elective postoperative neurosurgical patients require specific medical interventions and invasive monitoring. Among these, patients undergoing elective craniotomy are frequently admitted to neuro-ICU, specialist postanaesthesia care units or intermediate-level care unit in the postoperative period. Craniotomy patients have a high risk of neurological complications in the immediate postoperative period and might require advanced neuromonitoring, especially if sedation is continued in the ICU. Furthermore, the concept of enhanced recovery after surgery with the goal of improving functional capacity after surgery and decreasing morbidity has expanded to encompass neurosurgery. Postoperative clinical examination and neurological scores, bispectral index and simplified electroencephalography, and morning discharge huddles are the most used strategies in this context. Summary: After elective craniotomy, ICU admission should be warranted to patients who show new neurological deficits, especially when these include reduced consciousness or deficits of the lower cranial nerves, or have surgical indication for delayed extubation. Currently, evidence does not allow defining standardized protocol to guide ICU admission and postoperative neuromonitoring. Copyright (C) 2017 YEAR Wolters Kluwer Health, Inc. All rights reserved.

Evaluation and management of nonsyndromic congenital hearing loss.
Purpose of review: Nonsyndromic congenital hearing loss represents the largest proportion of paediatric sensorineural hearing loss. The optimal evaluation and management of affected patients remains clinically challenging. Current controversies in the diagnostic work-up of nonsyndromic congenital hearing loss are presented in this review. Recent findings: The improved diagnostic yield of comprehensive genetic testing due to new sequencing technologies is changing the diagnostic for congenital hearing loss. Concerns for both ionizing radiation and general anaesthetic exposure are also driving shifts in imaging modality preferences for infants and toddlers. Summary: A thoughtful systematic, targeted approach taking into consideration the audiologic phenotype of the patient is recommended for the work-up of nonsyndromic congenital hearing loss.

Current assessment of newborn hearing screening protocols.
Purpose of review: The objective of this article is to assess current newborn hearing screening protocols. We will focus on technologies or modalities used, protocol steps, training of screeners, timing of first screen, and loss to follow-up. A summary of program reports focusing on protocols from Greece, China, South Africa, France, Spain, South Korea, Denmark, Italy, Turkey, Taiwan, South Korea, Poland and Iran as they are recently reported will also be presented. Recent findings: Community-based hearing screening programs in South Africa and efforts in the Asian region are being reported. The use of automated auditory brainstem response and staged procedures are gaining popularity because of low refer rates. However, follow-up issues remain a problem. The importance of having trained nonprofessional screeners and an efficient database is becoming more evident as the number of newborns screened for hearing loss increase each year. Summary: There are many reported protocols using different technologies, involving several stages, implemented in different settings which should not confuse but rather guide stakeholders so that programs may attain certain benchmarks and ultimately help the hard-at-hearing child in achieving his or her full potential.

Increasing access to hearing rehabilitation for older adults.
Purpose of review: To provide an update on the recent research and policy developments affecting the current and future care of the 23 million older Americans with untreated hearing loss. Recent findings: Increasing evidence supports the association of age-related hearing loss with significant negative outcomes that affect the ability of older adults to age well. Despite an evolving understanding of the role hearing loss plays in the well being and vitality of older adults, the vast majority of older adults go untreated and hearing health care disparities exist. Recent work to understand the multitude of factors involved in hearing health care decisions, coupled with innovative approaches and technology to deliver hearing care, aim to provide more older adults with equal access to the tools needed to age well. Most importantly, significant national efforts and policy proposals substantiate these efforts and will be reviewed. Summary: Age-related hearing loss is a critical public health issue that affects almost all older adults. Through the application of novel approaches and perspectives, the delivery of hearing health care for older adults is evolving to provide more affordable and accessible care. Accompanying policy efforts provide the necessary support needed to increase access to care significantly. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved.

Invariant natural killer cells change after an oral allergy desensitization protocol for cow's milk
Abstract
Background
Cow milk (CM) allergy (CMA) affects up to 3% of the pediatric population and recent data suggest that only about 50% will outgrow by age 8. Oral immunotherapy (OIT) is a type of immune-modulating treatment that is able to induce desensitization to food allergens, to increase tolerance threshold, to reduce the risk of anaphylaxis, and to improve the patient's quality of life. The examination of the immunological changes observed during the establishment of food allergy (FA) desensitization in FA patients is a window into the pathogenesis of food allergy and food tolerance development. In this pathway, we have previously found that invariant natural killer T cells (iNKTs) are involved in CM allergy sensitization and now examine their role in OIT.
Methods
In this study, 10 of the 11 children with CM induced anaphylaxis enrolled in a CMA OIT clinical trial and completed the protocol. Peripheral blood iNKTs were quantitatively and qualitatively via flow cytometry characterized ex-vivo and after culture with milk lipids before and after completing the OIT protocol.
Results
After completing OIT for CM, children were able to reintroduce CM in their diet. For the first time, we demonstrated that OIT induced a significant increase in the peripheral blood iNKT, as well as their switch from a T helper (Th-2; i.e. IL-4, IL-13) to Th-1 (i.e. IFN-γ) cytokine profile.
Conclusions and clinical relevance
This study confirms the efficacy and safety of CM-OIT as well as the role of iNKT cells in CM allergy.

Stem cell derived gametes : a slippery slope towards designer babies?
Study question: Is the fear for designer babies a convincing argument against the development of stem cell derived (SCD-) gametes? Summary answer: Although SCD-gametes can facilitate the creation of designer babies, this need not undermine the entire enterprise of in vitro gamete derivation. What is known already: The dawn of new reproductive techniques is often accompanied by fears for eugenic practices, the creation of so-called designer babies in particular. The reproductive use of SCD-gametes feeds similar worries, in view of the possibility to select and design embryos with desired nondisease related traits. While such practices have a negative moral connotation, it should be investigated whether or not this moral worry is justified, both in terms of the scientific possibilities (state of the art), and the moral wrongness of selecting and or editing embryos in function of non-disease related traits. Study design, size, duration: A literature study was performed to delineate how the terms 'eugenics' and 'designer baby' are used and how they relate to each other. Next, claims in the scientific and ethical literature about how SCD-gametes may be used for eugenic purposes were inventoried. These claims were critically evaluated for scientific accurateness. Finally, we question whether the claimed possibility of selecting or genetically designing future offspring based on non-disease related traits is necessarily a morally bad thing. Participants/materials, setting, methods: Literature study, conceptual analysis, normative analysis. Main results and the role of chance: A first possibility is to produce large numbers of gametes (especially oocytes) and embryos to select genetic traits. Second, stem cells could be edited via CRISPR/Cas9 and differentiated into gametes. Third, SCD-gamete technology could be used to recombine SCDgametes with other gametes and derive gametes from the resulting embryos (and so on) to shape the genome through selective breeding, by combining desirable traits that arise in different embryos. Fourth, at present somatic cell nuclear transfer (SCNT) is hindered by the short supply of human oocytes. This could be overcome by means of SCD-gametes. By facilitating SCNT, SCD-gamete technology could ease the creation of embryos with the same genome as someone with a desirable genotype. A last possibility would be to create gametes from persons with desired traits (e.g. via induced pluripotent stem cells) and make these available via gamete banks. Each of these scenarios is premised upon further scientific developments. Given the rapid advance in CRISPR/Cas9, it might become possible to edit embryos so that SCD-gamete technology will be neither a sufficient nor a necessary condition to genetically design offspring. If SCD-gamete technology would become safe, it might nevertheless facilitate eugenic purposes, of which the moral wrongness remains contested. Limitations, reasons for caution: Gamete derivation from human stem cells is still in the research phase. The question of the moral wrongness of enhancement and eugenics is explored but not 'answered', as it is a fundamentally normative question. Similarly, 'designer baby' is a stipulative concept, as it is contested which interventions amount to 'designing'. Wider implications of the findings: The causal link between SCD-gamete technology and eugenics/designer babies is weak and speculative. Moreover, the wrongness of such an evolution is contested. Trial registration number: n/a.

Genetic diversity analysis of Moroccan lentil (Lens culinaris Medik.) landraces using Simple Sequence Repeat and Amplified Fragment Length Polymorphisms reveals functional adaptation towards agro-environmental origins
In the absence of previous molecular characterization, we assessed genetic diversity of 53 Moroccan lentil landraces including two local cultivars using simple sequence repeat (SSR) and amplified fragment length polymorphisms (AFLP). Nineteen SSRs yielded 213 alleles, and seven AFLP primer combinations gave 766 fragments of which 422 were polymorphic. Moderate to high genetic variation was observed. Several small groups of landraces were differentiated. Interestingly, one of the smallest groups contained short-cycle landraces with high early vegetative growth. Landraces in that group were from the dry land location of Abda, where they were likely selected for adaptation to drought and heat stress over centuries. Another group contained two landraces from highland areas that may have been selected for specific adaptation to cold stress. A third group contained one landrace from the Zear region known for its seed quality and has been proposed for the protected designation of origin (PDO) quality mark. Both techniques gave evidence of differentiation of the latter landrace supporting the idea of PDO attribution. Functional grouping according to agro-environmental origins, cycle duration and early vegetative vigour was observed.

Genetic variability for root and shoot traits in a lentil (Lens culinaris Medik.) recombinant inbred line population and their association with drought tolerance
Lentil (Lens culinaris Medik.) is usually grown under rainfed environments and often encounters drought stress from limited rainfall. Little information is available about shoot and root traits in association with drought tolerance. We studied variability for root and shoot traits related to drought tolerance using an F6–8 population of 133 recombinant inbred lines (RILs) from the cross ILL6002 × ILL5888. We found important variation between genotypes and also high variation in heritability values for root and shoot traits at 38 days after sowing the parents and RILs under both well-watered and drought-stressed treatments during two consecutive seasons in the greenhouse. The higher heritability values were obtained under drought stress treatment and suggest that selection in water-limited environments would be more effective in achieving genetic gains. Drought had reduced trait values, except root–shoot ratio that was likely to be enhanced underlying the importance of this trait for drought tolerance. The quantitative and continuous distributions of variation are the evidence for polygenic control of these traits and the possibility of mapping the quantitative trait loci (QTL). Statistically significant associations between root and shoot traits such as dry shoot biomass and chlorophyll content were noted, highlighting the reliability of indirect selection for underground traits (root) based on these aboveground traits in breeding programs. Significant correlations and regressions were demonstrated between dry root biomass, lateral root number, root surface area, dry shoot biomass, root–shoot ratio, chlorophyll content and drought tolerance as estimated by wilting severity from limited water supply. This shows the importance of a well-developed root system and early biomass development for drought tolerance. Identification and mapping of QTL related to studied traits in this population would be a first step for starting marker-assisted selection.

Evaluation and management of nonsyndromic congenital hearing loss.
Purpose of review: Nonsyndromic congenital hearing loss represents the largest proportion of paediatric sensorineural hearing loss. The optimal evaluation and management of affected patients remains clinically challenging. Current controversies in the diagnostic work-up of nonsyndromic congenital hearing loss are presented in this review. Recent findings: The improved diagnostic yield of comprehensive genetic testing due to new sequencing technologies is changing the diagnostic for congenital hearing loss. Concerns for both ionizing radiation and general anaesthetic exposure are also driving shifts in imaging modality preferences for infants and toddlers. Summary: A thoughtful systematic, targeted approach taking into consideration the audiologic phenotype of the patient is recommended for the work-up of nonsyndromic congenital hearing loss.

Current assessment of newborn hearing screening protocols.
Purpose of review: The objective of this article is to assess current newborn hearing screening protocols. We will focus on technologies or modalities used, protocol steps, training of screeners, timing of first screen, and loss to follow-up. A summary of program reports focusing on protocols from Greece, China, South Africa, France, Spain, South Korea, Denmark, Italy, Turkey, Taiwan, South Korea, Poland and Iran as they are recently reported will also be presented. Recent findings: Community-based hearing screening programs in South Africa and efforts in the Asian region are being reported. The use of automated auditory brainstem response and staged procedures are gaining popularity because of low refer rates. However, follow-up issues remain a problem. The importance of having trained nonprofessional screeners and an efficient database is becoming more evident as the number of newborns screened for hearing loss increase each year. Summary: There are many reported protocols using different technologies, involving several stages, implemented in different settings which should not confuse but rather guide stakeholders so that programs may attain certain benchmarks and ultimately help the hard-at-hearing child in achieving his or her full potential.

Role of Sigma-1 Receptor/p38 MAPK Inhibition in Acupoint Catgut Embedding-Mediated Analgesic Effects in Complete Freund's Adjuvant-Induced Inflammatory Pain.
BACKGROUND: The endoplasmic reticulum chaperone protein Sigma-1 receptor (Sig-1 R) and mitogen-activated protein kinases (MAPKs) are involved in the mechanism of pain. Acupoint stimulation exerts an exact antihyperalgesic effect in inflammatory pain. However, whether Sig-1 R and MAPKs are associated with the acupoint stimulation-induced analgesic effects is not clear. This study investigated the analgesic effect of acupoint catgut embedding (ACE) and the inhibition of Sig-1 R and MAPKs in ACE analgesia. METHODS: Rats were prepared with intrathecal catheter implantation. ACE was applied to bilateral "Kunlun" (BL60), "Zusanli" (ST36), and "Sanyinjiao" (SP6) acupoints in the rat model of inflammatory pain (complete Freund's adjuvant [CFA] intraplantar injection). Then, Sig-1R agonist PRE084 or saline was intrathecally given daily. The paw withdrawal thresholds and paw edema were measured before CFA injection and at 1, 3, and 5 day after CFA injection. Western bolt was used to evaluate the protein expression of spinal Sig-1R, p38MAPK, and extracellular signal-regulated kinase (ERK), and immunohistochemistry of Sig-1R was detected at 1, 3, and 5 days after CFA injection. RESULTS: ACE exhibited specific analgesic effects. ACE increased paw withdrawal thresholds and markedly decreased CFA-induced paw edema at 1, 3, and 5 days. ACE downregulated the protein expression of Sig-1R, which was increased significantly at 1, 3, and 5 days after CFA injection. ACE decreased the expression of p38 MAPK and ERK at 1 and 3 days but not at 5 days. However, an injection of Sig-1R agonist PRE084 markedly reversed these alterations, except ERK expression. CONCLUSIONS: The present study demonstrated that ACE exhibited antihyperalgesic effects via the inhibition of the Sig-1R that modulated p38 MAPK, but not ERK, expression in the CFA-induced inflammatory pain model in rats.
