AbstractResource use was investigated at 34 Litopenaeus vannamei and five Penaeus monodon farms in Thailand and 30 L. vannamei and 24 P. monodon farms in Vietnam. Farms varied in water surface areas for production, reservoirs, canals, and settling basins; in pond size and depth; and in water management, stocking density, feeding rate, amendment input, aeration rate, crop duration, and crops per year. Production of L. vannamei averaged 17.3 and 10.9 m.t./ha/yr, and feed conversion ratio averaged 1.49 and 1.33 in Thailand and Vietnam, respectively. On average, production of 1 m.t. of L. vannamei required 0.58 ha land, 5,400 m3 water, 60 GJ energy, and 1218 kg wildfish in Thailand and 1.76 ha land, 15,100 m3 water, 33.7 GJ energy, and 1264 kg wildfish in Vietnam. Resource use per metric ton of shrimp declined with greater production intensity. In Thailand, P. monodon was produced at 0.2–0.4 m.t./ha/yr, with no inputs but water and postlarvae. In Vietnam, P. monodon production averaged 3.60 m.t./ha/yr. Production of 1 m.t. of P. monodon required 0.80 ha land, 36,000 m3 water, 47.8 GJ energy, and 1180 kg wildfish, and resource use per ton production declined with increasing production intensity.

BackgroundAtrioventricular (AV) block is rare in Takotsubo cardiomyopathy (TC).Case reportA 66‐year‐old female presented with fatigue. Her electrocardiogram revealed 3:2 Mobitz Type II AV block, confirmed to be supra‐Hisian by electrophysiological study. Echocardiogram and left ventricular angiogram showed moderate left ventricular dysfunction and apical ballooning, whereas coronary angiogram revealed mildly ectatic coronaries. At 2 weeks AV block persisted, needing permanent pacemaker implantation. At 1‐month follow‐up, she had normal ventricular function and no AV block.ConclusionDelayed recovery of AV conduction is possible in TC, thus implying to wait for a longer period before implanting a pacemaker.

Published: December 2016

SummaryHeterogeneity of BRAF mutation in melanoma has been a controversial subject. Quantitative data on BRAF allele frequency (AF) are sparse, and the potential relationship with response to BRAF inhibitors (BRAFi) in patients with metastatic melanoma is unknown. We quantitatively measured BRAF AF in a cohort of treatment naïve metastatic melanoma samples by pyrosequencing and correlated with survival data in patients treated with BRAFi as part of their clinical care. Fifty‐two samples from 50 patients were analysed. BRAF V600E mutations were detected in 71.1% of samples followed by V600K (25%) and V600R (3.9%). There was a wide range of AF from 3.9% to 80.3% (median 41.3%). In 33 patients treated with BRAFi, there was no difference in overall or progression‐free survival when the patients were categorized into high or low AF groups. There was no correlation between AF and degree of response, and no difference in survival based on genotype.

Published: December 2016

AbstractIMT, previously known as IPT, is a relatively rare tumor that was originally described in the lungs, but case reports have reported the tumor in almost every organ system. Surgical resection is typically the mainstay of therapy; however, tumors have also been shown to respond to chemotherapy or anti‐inflammatory therapy and some have spontaneously regressed. We present a literature review and case report representing the first documentation to date of liver transplant combined with PD for surgical resection of a myofibroblastic tumor non‐responsive to medical therapy.
Reliability of periodontal diagnostic tools for monitoring peri‐implant health and disease

Published: December 2016

AbstractThe prevalence, causes and consequences of crestal bone loss at dental implants are a matter of debate. In recent years, a high prevalence of peri‐implant soft‐tissue inflammation, associated with peri‐implant bone loss, has been reported and the need for treatments similar to those offered for natural teeth affected by periodontitis has been proposed. This suggestion is based on the assumption that periodontal indices, such as probing pocket depth and bleeding on probing, are reliable indicators of the peri‐implant tissue conditions and good predictors of future bone loss. However, based on a critical review of the literature in the present paper, it is concluded that periodontal indices are not reliable either for identifying peri‐implant disease or for predicting future risk for peri‐implant crestal bone loss and implant failure. The long‐term experiences with dental implants, presented in the literature, indicate that the presence of bleeding on probing, probing pocket depths much larger than 4 mm and some bone loss seem to reflect, in most instances, normal conditions of well‐functioning dental implants, bearing in mind that healing of dental implants is the result of a foreign body reaction with the formation of scar tissue. Therefore, the use of probing pocket depth and bleeding on probing assessments may lead to over‐diagnosis and possibly to over‐treatment of assumed biofilm‐mediated peri‐implantitis lesions. It is the opinion of the authors of this review that a treatment should only be initiated when a clinical problem is present based on patient's symptoms (discomfort, pain), the presence of swelling, redness and pus, and significant crestal bone loss over time (as verified with radiographs). The treatment should aim at resolving the infection, which could include removal of the implant.
Clinical relevance of dimensional bone and soft tissue alterations post‐extraction in esthetic sites
Authors: Chappuis Vivianne , Araújo Mauricio G. , Buser Daniel 
Published: December 2016

AbstractThe key to achieving pleasing esthetics in implant dentistry is a thorough understanding of the biological processes driving dimensional bone and soft tissue alterations post‐extraction. The aim of the present report is first to characterize the extent of bone and soft tissue changes post‐extraction and second to identify potential factors influencing tissue preservation in order to facilitate successful treatment outcomes. The facial bone wall thickness has been identified as the most critical factor influencing bone resorption and can be used as a prognostic tool in order to identify sites at risk for future facial bone loss subsequent to tooth extraction. Clinical studies indicated that thin bone wall phenotypes exhibiting a facial bone wall thickness of 1 mm or less revealed progressive bone resorption with a vertical loss of 7.5 mm, whereas thick bone wall phenotypes showed only minor bone resorption with a vertical loss of 1.1 mm. This is in contrast to the dimensional soft tissue alterations. Thin bone wall phenotypes revealed a spontaneous soft tissue thickening after flapless extraction by a factor of seven, whereas thick bone wall phenotypes showed no significant changes in the soft tissue dimensions after 8 weeks of healing. In sites exhibiting a limited bone resorption rate, immediate implant placement may be considered. If such ideal conditions are not present, other timing protocols are recommended to achieve predictable and pleasing esthetics. Socket preservation techniques for ridge preservation utilizing different biomaterials and/or barrier membranes often result in a better maintenance of tissue volumes, although the inevitable biological process of post‐extraction bone resorption and bone modeling cannot be arrested. In summary, the knowledge of the biological events driving dimensional tissue alterations post‐extraction should be integrated into the comprehensive treatment plan in order to limit tissue loss and to maximize esthetic outcomes.
Implant placement post extraction in esthetic single tooth sites: when immediate, when early, when late?

Published: December 2016

AbstractImplant placement in post‐extraction sites of single teeth in the esthetic zone has been a topic of great interest in the field of implant dentistry since 1990. Triggered by the development of guided bone regeneration, the concept of immediate implant placement became quite popular in the 1990s. In the past 12 years, however, the dental community has begun to focus increasingly on the esthetic outcomes of post‐extraction implant placement and several studies indicated a significant risk for the development of mucosal recessions with immediate implants. Parallel with this, significant progress has been made in the understanding of tissue biology in terms of hard and soft tissue alterations post extraction, based on preclinical, clinical and radiological studies. This knowledge has helped better to understand the etiology of these esthetic complications with immediate implant placement. The present review first analyzes the various phases of the development of therapeutic strategies over the years for post‐extraction implant placement in single tooth sites in the esthetic zone. It presents the current knowledge concerning the terminology with immediate, early and late implant placement, the risk factors for the development of esthetic complications, and the selection criteria for the various treatment options. In the second part, clinical recommendations are given, since a clinician active in this field of implant therapy can use all treatment options depending on the preoperative analysis including a 3D cone beam computed tomography. The selection criteria for all four treatment options are presented and documented with typical case reports to illustrate the current treatment approaches applied in daily practice.
Coverage of mucosal recessions at dental implants

Published: December 2016

AbstractFacial peri‐implant mucosal recessions represent an increasing complication in implant dentistry and may negatively affect the esthetic outcome and patient satisfaction. The aim of the present paper is to provide a review on the potential causes of facial peri‐implant mucosal recessions and to provide a rationale for treatment along with possible treatment options. The available data indicate that soft tissue augmentation around dental implants is possible, but at present there is no evidence demonstrating that the augmented soft tissues are able to influence the peri‐implant bone levels (e.g. to limit peri‐implant bone loss). Therefore, the rationale to cover or correct peri‐implant mucosal recessions are (i) to optimize the possibility for performing an adequate level of oral hygiene, and (ii) to improve esthetics. At present, there is very limited evidence supporting any specific treatment modality for covering peri‐implant soft tissue recessions. The limited available data indicate that only shallow peri‐implant mucosal recessions (e.g. up to 2 mm) may be treated successfully by means of a coronally advanced flap and subepithelial connective tissue graft or with guided bone regeneration, while no data are available supporting the possibility of covering deep and large peri‐implant mucosal recessions.
Combating the scientific decline effect with confidence (intervals)
Authors: Groppe David M. 
Published: December 2016

AbstractA symptom of the need for greater reproducibility in scientific practice is the decline effect—the fact that the size of many experimental effects decline with subsequent study or fail to replicate entirely. A simple way to combat this problem is for scientists to more routinely use confidence intervals (CIs) in their work. CIs provide frequentist bounds on the true size of an effect and can reveal when a statistically significant effect is possibly too small to be reliable or when a large effect might have been missed due to insufficient statistical power. CIs are often lacking in psychophysiological reports, likely due to the large number of dependent variables, which complicates deriving and visualizing CIs. In this article, I explain the value of CIs and show how to compute them for analyses involving multiple variables in various ways that adjust the intervals for the greater uncertainty induced by multiple statistical comparisons. The methods are illustrated using a basic visual oddball ERP dataset and freely available MATLAB software.
Considering ERP difference scores as individual difference measures: Issues with subtraction and alternative approaches

Published: December 2016

AbstractThere is growing interest in psychophysiological and neural correlates of psychopathology, personality, and other individual differences. Many studies correlate a criterion individual difference variable (e.g., anxiety) with a psychophysiological measurement derived by subtracting scores taken from two within‐subject conditions. These subtraction‐based difference scores are intended to increase specificity by isolating variability of interest. Using data on the error‐related negativity (ERN) and correct response negativity (CRN) in relation to generalized anxiety disorder (GAD), we highlight several conceptual and practical issues with subtraction‐based difference scores and propose alternative approaches based on regression. We show that ERN and CRN are highly correlated, and that the ΔERN (i.e., ERN − CRN) is correlated in opposite directions both with ERN and CRN. Bivariate analyses indicate that GAD is related to ΔERN and ERN, but not CRN. We first show that, by using residualized scores, GAD relates both to a larger ERN and smaller CRN. Moreover, by probing the interaction of ERN and CRN, we show that the relationship between GAD and ERN varies by CRN. These latter findings are not evident when using traditional subtraction‐based difference scores. We then completed follow‐up analyses that suggested that an increased P300 in anxious individuals gave rise to the apparent anxiety/CRN relationship observed. These findings have important conceptual implications for facilitating the interpretability of results from individual difference studies of psychophysiology.
Dealing with ocular artifacts on lateralized ERPs in studies of visual‐spatial attention and memory: ICA correction versus epoch rejection
Authors: Drisdelle Brandi Lee , Aubin Sébrina , Jolicoeur Pierre 
Published: December 2016

AbstractThe objective of the present study was to assess the robustness and reliability of independent component analysis (ICA) as a method for ocular artifact correction in electrophysiological studies of visual‐spatial attention and memory. The N2pc and sustained posterior contralateral negativity (SPCN), electrophysiological markers of visual‐spatial attention and memory, respectively, are lateralized posterior ERPs typically observed following the presentation of lateral stimuli (targets and distractors) along with instructions to maintain fixation on the center of the visual search for the entire trial. Traditionally, trials in which subjects may have displaced their gaze are rejected based on a cutoff threshold, minimizing electrophysiological contamination by saccades. Given the loss of data resulting from rejection, we examined ocular correction by comparing results using standard fixation instructions against a condition where subjects were instructed to shift their gaze toward possible targets. Both conditions were analyzed using a rejection threshold and ICA correction for saccade activity management. Results demonstrate that ICA conserves data that would have otherwise been removed and leaves the underlying neural activity intact, as demonstrated by experimental manipulations previously shown to modulate the N2pc and the SPCN. Not only does ICA salvage and not distort data, but also large eye movements had only subtle effects. Overall, the findings provide convincing evidence for ICA correction for not only special cases (e.g., subjects did not follow fixation instruction) but also as a candidate for standard ocular artifact management in electrophysiological studies interested in visual‐spatial attention and memory.

Published: December 2016

AbstractData from two studies were used to estimate the reliability of facial EMG when used to index facial mimicry (Study 1) or affective reactions to pictorial stimuli (Study 2). Results for individual muscle sites varied between muscles and depending on data treatment. For difference scores, acceptable internal consistencies were found only for corrugator supercilii, and test‐retest reliabilities were low. For contrast measures describing patterns of reactions to stimuli, such as high zygomaticus major combined with low corrugator supercilii, acceptable internal consistencies were found for facial reactions to smiling faces and positive affective reactions to affiliative images (Study 2). Facial reactions to negative emotions (Study 1) and facial reactions to power and somewhat less to achievement imagery (Study 2) showed unsatisfactory internal consistencies. For contrast measures, good temporal stability over 24 months (Study 1) and 15 months (Study 2), respectively, was obtained. In Study 1, the effect of method factors such as mode of presentation was more reliable than the emotion effect. Overall, people's facial reactions to affective stimuli seem to be influenced by a variety of factors other than the emotion‐eliciting element per se, which resulted in biased internal consistency estimates. However, the influence of these factors in turn seemed to be stable over time.
Beyond Profiling: The Institutional Sources of Racial Disparities in Policing
Authors: Epp Charles R. , Maynard‐Moody Steven , Haider‐Markel Donald 
Published: December 2016

AbstractAmerican policing faces a crisis of legitimacy. A key source of this crisis is a widespread police practice commonly endorsed by police leaders to fight crime. This is the investigatory stop, used to check out people who seem suspicious and to seize illegal drugs and guns and make arrests. Using data from an original scientific survey of drivers in the Kansas City metropolitan area, the authors show that racial disparities in police stops are concentrated in investigatory vehicle stops. In these stops, but not others, officers disproportionately stop African Americans and question and search them. The overwhelming majority of people stopped in this way are innocent, and the experience causes psychological harm and erodes trust in and cooperation with the police. Many of the most controversial police shootings during the past two years occurred in these stops. Reforming this practice is an essential step toward restoring trust in the police.
Collective Leadership and Context in Public Administration: Bridging Public Leadership Research and Leadership Studies
Authors: Ospina Sonia M. 
Published: December 2016

AbstractThis article challenges the view that public leadership research should maintain a separate perspective in the study of public leadership. It discusses the benefits of further embedding the public leadership research domain within leadership studies, constructing a cross‐fertilization that contributes to advance both. The article maps key concerns in relational leadership theories, contrasting them with current work in the public leadership research domain and offering suggestions to close the gap. It highlights public leadership scholarship's competitive advantage to contribute to theorizing about leadership, given the importance of context for building contemporary theories of relational leadership.

ABSTRACT
Background and objectiveBoth patients with cardiac diseases as well as those with COPD report an impaired health status. The frequencies of objectively assessed co‐morbid cardiac diseases and their impact on health status in patients with COPD are unknown. We aimed to investigate echocardiographic abnormalities and their impact on health status in a large cohort of patients with COPD referred for pulmonary rehabilitation (PR).MethodsIn this cross‐sectional, observational analyses, demographic and clinical characteristics were assessed during an inpatient pre‐PR assessment. All patients underwent Doppler echocardiographic evaluation. Health status was assessed using the COPD Assessment Test (CAT), Clinical COPD Questionnaire (CCQ) and St George's Respiratory Questionnaire (SGRQ).ResultsA total of 514 patients (55.3% males, age: 64.1 (9.1) years, forced expiratory volume in 1 s (FEV1
): 48.6 (20.0) % predicted) were included for analyses. Two hundred and seventy‐six patients (53.7%) were diagnosed with one or more echocardiographic abnormalities. Most prevalent were left ventricular (LV) hypertrophy (LVH, 31.0%), increased right ventricular systolic pressure (RVSP, 20.4%) and impaired LV ejection fraction (LVEF, 16.5%). Of the 276 patients, 176 (63.8%) with echocardiographic abnormalities did not have these recorded in their medical history. Patients with echocardiographic abnormalities reported a worse health status as assessed with the SGRQ total score (62.5 (17.1) vs 59.3 (17.6) points, P = 0.044). CCQ and CAT did not differ between groups.ConclusionMore than half of the patients referred to PR had echocardiographic abnormalities of which two‐third did not have them recorded in their medical history. We detected a limited impact of echocardiographic abnormalities on health status.
