Published: October 2018

ABSTRACT
The dynamic climate within health care policy-making and academia, in conjunction with updated Emergency Nurse Practitioner (ENP) competencies and a recent role delineation study, supports development of standardized curricula to ensure appropriate preparation for practice. Emergency NP curricular content should align with the updated ENP Practice Standards and National Organization of Nurse Practitioner Faculties' competencies for the Core and Family NP. This article provides rationale for establishing standardized educational curricula for ENP programs, delineates core specialty curricular content for inclusion, and discusses applicability of ENP specialty competencies within graduate academic education and postgraduate fellowship programs. As national ENP program curricula are standardized, clarity of the ENP specialty role will be enhanced and educational outcomes can be uniformly evaluated.
Colchicine: an affordable anti-inflammatory agent for atherosclerosis
Authors: Thompson Peter L. , Nidorf S. Mark 
Published: October 2018

Purpose of review
Inflammation has been shown to be central to the development and progression of atherosclerosis. Despite detailed understanding of its central role and the cellular dynamics, which contribute to atherosclerotic inflammation, there has been slow progress in finding suitable agents to treat it. The recent CANTOS trial showed that the interleukin-1β inhibitor canakinumab can improve outcomes after acute coronary syndromes. Being a monoclonal antibody, it is expensive and inconvenient to administer for long-term treatment. This review summarizes recent work in finding effective, affordable alternatives to canakinumab.

Recent findings
Statin drugs have anti-inflammatory properties but separating their LDL lowering effect from their anti-inflammatory effect has been difficult. Drugs acting on targets outside of the interleukin-1β (IL-1β) pathway have been tested without finding a suitable candidate. Following the proof of principle provided by the success of canakinumab, other candidates targeting the IL-1β pathway are undergoing detailed evaluation. The most likely candidates are low-dose methotrexate and low-dose colchicine. The potential mechanisms and ongoing clinical trials are described.

Summary
Targeting the IL-1β pathway has already been successful with canakinumab but its expense and inconvenience of administration may limit its widespread uptake for controlling inflammation in atherosclerosis. Low-dose methotrexate and low-dose colchicine are affordable and more accessible alternatives, currently undergoing detailed evaluation for safety and efficacy in large randomized controlled trials.

ABSTRACTObjective:The aim of the study was to describe clinical, epidemiological, and management characteristics of food protein‐induced enterocolitis syndrome (FPIES) cases in Spain.Patients and Methods:Multicenter observational retrospective study. FPIES cases diagnosed in specialized units in Spain over 12 months in 2017 (January–December) according to the recently published international diagnostic criteria were included.Results:One hundred twenty patients (53.3% boys) were included. The majority were acute cases (111) with mild‐to‐moderate severity (76.7%). Triggering foods were cow's milk (48/120), fish (38), egg (13), rice (12), and soy (1). The majority (84.2%) of the patients had FPIES to 1 food only. In addition to vomiting (100%), pallor (89.2%), and altered behavior (88.3%) were most frequently observed in acute forms. On the contrary, diarrhea (70%), abdominal distension (33.3%), and blood in stools (44.4%) were more frequently observed in chronic cases. Oral challenge was performed in 18.9% of the acute forms compared to 44.4% of the chronic forms. The most common treatment was intravenous fluids followed by ondansetron. Corticosteroids were used in 6 patients (5 with acute symptoms and 1 chronic). Seven patients were treated with antibiotics for suspicion of infection. Most cases of cow's milk FPIES were treated with extensively hydrolyzed formulas (69.8%).Conclusions:FPIES is not uncommon in our units. Unlike other published series, fish and egg are important triggers in our country. A greater knowledge and diffusion of the international consensus criteria will allow a better characterization of the cases and a standardization of their management.
Treatment of influenza with neuraminidase inhibitors
Authors: Beard Kate R. , Brendish Nathan J. , Clark Tristan W. 
Published: October 2018

Purpose of review
Seasonal and pandemic influenza are major causes of morbidity and mortality globally. Neuraminidase inhibitors (NAIs) are the only class of antiviral agent recommended for the treatment of currently circulating strains of influenza. There has previously been controversy over the level of evidence for patient benefit with NAIs. We review here the current evidence base for the clinical impact of treatment of influenza with NAIs.

Recent findings
Meta-analysis of pharma-sponsored studies (including previously unpublished data) shows that NAIs reduce the duration of illness in influenza-infected patients, and suggest a possible reduction in the rate of complications and hospitalization. Meta-analysis of observational studies examining oseltamivir use during the H1N1 2009 pandemic, suggest a reduction in hospitalization rate in community-dwelling patients and a reduction in mortality in hospitalized adults treated with NAIs. Current NAI use in the community and hospitals varies widely but in general they are underutilized.

Summary
Although there has been controversy over the level of evidence for patient benefit, a growing body of evidence suggests that treatment of influenza with NAIs is associated with improved outcomes for both patients in the community and more severely unwell patients in hospital. Clinical outcomes are optimal with earlier use and strategies to improve early widespread NAI utilization are needed.
The Use of a Double Suture and Conjunctival Cuts in the Lateral Tarsal Strip: A New Approach to Involutional Ectropion
Authors: Meduri Alessandro , Inferrera Leandro , Oliverio Giovanni William , Tumminello Giuseppe , Rechichi Miguel , Mazzotta Cosimo , Frisina Rino , Kaufman Stephen , Aragona Pasquale 
Published: October 2018

Purpose:
To describe the use of a double suture and conjunctival cuts in the lateral tarsal strip (LTS) and to evaluate postsurgical outcome in patients with severe involutional ectropion.

Methods:
A prospective randomized study was conducted on 16 eyelids of 8 patients with symptomatic severe involutional ectropion. The 8 patients were between 62 and 79 years. They were distributed into 2 groups consisting of 4 patients each. The control group was treated with a conventional lateral tarsal strip (C-LTS), the second group underwent a modified lateral tarsal strip (M-LTS). The mean follow-up was 18 months. Success was defined as relief in lid laxity. The recurrence rate was also evaluated.

Results:
Patients treated with M-LTS showed lower horizontal laxity (3.5 ± 0.2) than patients treated with C-LTS (5.7 ± 0.2). During the 18-month follow-up, a statistically significant difference was found between the 2 groups with P value <0.05.

Conclusions:
The use of a double suture and conjunctival cuts in the lateral tarsal strip proposed by Meduri showed a reduction of postsurgical ectropion's grade and postsurgical recurrences. This technique could be used for the treatment of patients with a severe ectropion.

Published: October 2018

Abstract
The aim of this study was to evaluate the clinical outcomes of cerebrospinal fluid (CSF) rhinorrhea in patients treated with transcranial surgery. Here, we retrospectively reviewed 23 patients with CSF rhinorrhea between 2008 and 2015 at our university hospital. Nine (39.1%) patients were treated conservatively, whereas 12 (52.2%) patients were treated with a transcranial approach. Our results showed that 7 (30.4%), 11 (47.8%), and 5 (21.7%) patients had spontaneous, traumatic, and iatrogenic CSF leakage, respectively. In our study, the cribriform plate was the most common site of leakage, and it was found to be involved in 5 (21.7%) patients. The mean diameter defect of the fistula was 130.40 ± 190.47 mm2 and there was no significant difference between this defect and the different etiology types. In our study, meningitis, third nerve palsy, and vasospasm were the main complications that arose during the treatment of CSF rhinorrhea. Moreover, 6 (26.1%) of 7 (30.4%) patients had spontaneous CSF leaks that were treated with surgery. Notably, spontaneous CSF leaks did not stop when treated with conservative measures. In addition, there were no significant differences between etiology types and CSF leaks. The primary surgical repair rate was 78.3% and the secondary surgery repair rate was 91.6%. Importantly, as we preferred using this type of transcranial surgery in our clinic, there has been a higher success rate with endoscopic treatments and fewer major complications from CSF rhinorrhea in the literature.

Published: October 2018

Abstract
The sphenoid sinus is located in the center of the cranial base and is surrounded by numerous neurovascular structures. The aim of this study was to determine sphenoid sinus types and subtypes, dimensions of the sinus and cranium, and the relations of these to age and gender.
Computed tomography data was obtained from 144 patients to determine right sphenoidal volume (sphVOLR), left sphenoidal volume (sphVOLL), total sphenoidal volume (sphVOLT), anteroposterior length of the sphenoid sinus (sphAP), laterolateral length of the sphenoid sinus (sphLL), head circumference (crHC), fronto-occipital length (crFO), and biparietal length (crBP), with OSIRIX software. The patients’ ages ranged between 9 and 83 years (mean age 38 ± 15.5 years). The study included 89 males (mean age 39 ± 15.5 years) and 55 females (mean age 38 ± 15.6 years).
Conchal (1.4%), presellar (8.3%), sellar (23.6%), and postsellar (66.7%) type sphenoid sinuses were determined based on the extension of pneumatization around the sella turcica. Each type of sphenoid sinus was classified into the following 5 types based on the direction of pneumatization: body, full lateral, pterygoid, lesser wing, and greater wing subtypes. Mean sphAP was determined as 29.72 mm and mean sphLL as 37.73 mm. In 5 patients only (3.4%), the sphenoid sinus was not divided into right and left by the intersphenoidal septum.
The variations in the extensions of pneumatization of the sphenoid sinus and its dimensions might be used to estimate the selection of a surgical approach to lesions bordering the sinus.

Published: October 2018

Abstract
In the present study, it was aimed to perform the morphometric analysis of the hard and soft palate in fetal cadavers and evaluate hard palate asymmetry during the fetal development. The development of the palate was investigated in 40 (21 males, 19 females) fetal materials aged between the 17th and 40th gestational week. In this study, distances between the incisive papilla-staurion (Ip-Sr), staurion-posterior nasal spine (Sr-Pns), incisive papilla-greater palatine foramen (Ip-Gpf) on the right and left sides, Sr-Gpf, and Pns-Gpf were measured. In cases with asymmetry, the ratio of asymmetry was determined in percentage using the asymmetry index. Moreover, angular values between Ip-Sr-Gpf and Ip-Pns-Gpf on the right and left sides were measured, and the right and left side values were compared with each other. The hard and soft palate lengths were measured on the planum medianum. Upon comparing the measured parameters between males and females, the mean values of male fetuses were higher in all parameters, but a significant difference was found only in the Sr-Pns distance among these parameters. Upon comparing the angular data and asymmetry index data on the hard palate between the trimester groups, a significant difference was found only in the Ip-Sr-Gpf (left) parameter. The mean ratio of the hard palate to the soft palate was found as 1.90. It is believed that the obtained data will contribute to studies to be conducted in fields such as plastic surgery, maxillofacial surgery, intrauterine surgery, fetopathology, embryology, anatomy, and obstetrics.

AbstractBackgroundOne of the most common copy number variants, the 22q11.2 microdeletion, confers an increased risk for schizophrenia. Since schizophrenia has been associated with an aberrant neural response to repeated stimuli through both reduced adaptation and prediction, we here hypothesized that this may also be the case in nonpsychotic individuals with a 22q11.2 deletion.MethodsWe recorded high-density EEG from 19 individuals with 22q11.2 deletion syndrome (12-25 years), as well as 27 healthy volunteers with comparable age and sex distribution, while they listened to a sequence of sounds arranged in a roving oddball paradigm. Using posterior probability maps and dynamic causal modelling we tested three different models accounting for repetition dependent changes in cortical responses as well as in effective connectivity; namely an adaptation model, a prediction model, and a model including both adaptation and prediction.ResultsRepetition-dependent changes were parametrically modulated by a combination of adaptation and prediction and were apparent in both cortical responses and in the underlying effective connectivity. This effect was reduced in individuals with a 22q11.2 deletion and was negatively correlated with negative symptom severity. Follow-up analysis showed that the reduced effect of the combined adaptation and prediction model seen in individuals with 22q11.2 deletion was driven by reduced adaptation rather than prediction failure.ConclusionsOur findings suggest that adaptation is reduced in individuals with a 22q11.2 deletion, which can be interpreted in light of the framework of predictive coding as a failure to suppress prediction errors.

AbstractInter-areal synchronization of neuronal oscillations below 100 Hz is ubiquitous in cortical circuitry and thought to regulate neuronal communication. In contrast, faster activities are generally considered to be exclusively local-circuit phenomena. We show with human intracerebral recordings that 100–300 Hz high-gamma activity (HGA) may be synchronized between widely distributed regions. HGA synchronization was not attributable to artefacts or to epileptic pathophysiology. Instead, HGA synchronization exhibited a reliable cortical connectivity and community structures, and a laminar profile opposite to that of lower frequencies. Importantly, HGA synchronization among functional brain systems during non-REM sleep was distinct from that in resting state. Moreover, HGA synchronization was transiently enhanced for correctly inhibited responses in a Go/NoGo task. These findings show that HGA synchronization constitutes a new, functionally significant form of neuronal spike-timing relationships in brain activity. We suggest that HGA synchronization reflects the temporal microstructure of spiking-based neuronal communication per se in cortical circuits.
Microridges are apical projections formed of branched F-actin networks that organize the glycan layer

Published: October 2018

AbstractApical projections are integral functional units of epithelial cells. Microvilli and stereocilia are cylindrical apical projections that are formed of bundled actin. Microridges on the other hand, grow laterally long, forming labyrinthine patterns on surfaces of various kinds of squamous epithelial cells. So far, the structural organization and functions of microridges have remained elusive. We have analyzed microridges on zebrafish epidermal cells using confocal and electron microscopy methods including electron tomography, to show that a microridge is formed of a network of F-actin and requires the function of the Arp2/3 complex for its maintenance. During development, microridges begin as F-actin punctae showing signatures of branching and requiring an active Arp2/3 complex. Using inhibitors of actin polymerization and the Arp2/3 complex, we show that microridges organize the surface glycan layer. Our analyses have unraveled the F-actin organization supporting the most abundant and evolutionarily conserved apical projection, which functions in glycan organization.

ABSTRACTParental effects are an important source of adaptive traits. By contrast, parental effects failing to regulate offspring phenotype to fit current conditions could be deleterious. Although adaptive parental responses to single cues have been identified, we lack an understanding of the reversibility of parental effects across breeding cycles in a fluctuating environment. Social status of parents can occasionally fluctuate and, in turn, influence high-fitness pathways available to offspring. We show that social competition status results in robust parental effects on growth in mice. Dominant males produce faster growing offspring because of status related cues, not genetic associations. The timing, effect-size, and sex-specificity of this paternal effect are modulated by maternal experience. We experimentally demonstrate that status-ascending males produce heavier sons than before, and status-descending males produce lighter sons than before. Paternal status predicts genome-wide transcription in the liver, including transcriptional networks controlling xenobiotic and fatty acid metabolism, and oxidative phosphorylation. Our study demonstrates that paternal social status reversibly conditions offspring growth in naturalistic environments.
Non-functional and weak alleles of FRIGIDA and FLOWERING LOCUS C reduce lifetime water-use independent of leaf-level water-use-efficiency traits in Arabidopsis thaliana

AbstractNatural selection driven by water availability has resulted in considerable variation for traits associated with drought tolerance and leaf level water-use efficiency (WUE). In Arabidopsis, little is known about the variation of whole-plant water use (PWU) and whole-plant WUE (TE). To investigate the genetic basis of PWU, we developed a novel proxy trait by combining flowering time and rosette water use to estimate lifetime PWU. We validated its usefulness for large scale screening of mapping populations in a subset of ecotypes. This parameter subsequently facilitated the screening of water-use but also drought tolerance traits in a recombinant inbred line population derived from two Arabidopsis accessions with distinct water use strategies, namely C24 (low PWU) and Col-0 (high PWU). Subsequent quantitative trait loci (QTL) mapping and validation through near-isogenic lines identified two causal QTLs, which showed that a combination of weak and non-functional alleles of the FRIGIDA (FRI) and FLOWERING LOCUS C (FLC) genes substantially reduced plant water-use without penalising reproductive performance. Drought tolerance traits, stomatal conductance, intrinsic water use efficiency (δ13C) and rosette water-use were independent of allelic variation at FRI and FLC, suggesting that flowering is critical in determining life-time plant water use, but not leaf-level traits.
The genetics of morphological and behavioural island traits in deer mice
Authors: Baier Felix , Hoekstra Hopi E. 
Published: October 2018

ABSTRACTAnimals on islands often exhibit dramatic differences in morphology and behaviour compared to mainland individuals, a phenomenon known as the “island syndrome”. These differences are thought to be adaptations to island environments, but the extent to which they have a genetic basis or instead represent plastic responses to environmental extremes is often unknown. Here, we revisit a classic case of island syndrome in deer mice (Peromyscus maniculatus) from British Columbia. We first show that Saturna Island mice and those from neighbouring islands are ∼35% (∼5g) heavier than mainland mice and diverged approximately 10 thousand years ago. We then established laboratory colonies and find that Saturna Island mice are heavier both because they are longer and have disproportionately more lean mass. These trait differences are maintained in second-generation captive-born mice raised in a common environment. In addition, island-mainland hybrids reveal a maternal genetic effect on body weight. Using behavioural testing in the lab, we also find that wild-caught island mice are less aggressive than mainland mice; however, lab-raised mice born to these founders do not differ in aggression. Together, our results reveal that these mice respond differently to environmental conditions on islands – evolving both heritable changes in a morphological trait and also expressing a plastic phenotypic response in a behavioural trait.
