The Effects of Local Vibration on Balance, Power, and Self-Reported Pain After Exercise
Authors: Custer Lisa , Peer Kimberly S. , Miller Lauren 
Published: May 2016

Context:Muscle fatigue and acute muscle soreness occur after exercise. Application of a local vibration intervention may reduce the consequences of fatigue and soreness.Objective:To examine the effects of a local vibration intervention after a bout of exercise on balance, power, and self-reported pain.Design:Single-blind crossover study.Setting:Laboratory.Participants:19 healthy, moderately active subjects.Interventions:After a 30-min bout of full-body exercise, subjects received either an active or a sham vibration intervention. The active vibration intervention was performed bilaterally over the muscle bellies of the triceps surae, quadriceps, hamstrings, and gluteals. At least 1 wk later, subjects repeated the bout, receiving the other vibration intervention.Main Outcome Measures:Static balance, dynamic balance, power, and self-reported pain were measured at baseline, after the vibration intervention, and 24 h postexercise.Results:After the bout of exercise, subjects had reduced static and dynamic balance and increased self-reported pain regardless of vibration intervention. There were no differences between outcome measures between the active and sham vibration conditions.Conclusions:The local vibration intervention did not affect balance, power, or self-reported pain.
The Diagnostic Accuracy of Clinical Diagnostic Tests for Thoracic Outlet Syndrome
Authors: Hixson Krista M. , Horris Hannah B. , McLeod Tamara C. Valovich , Bacon Cailee E. Welch 
Published: May 2016

Clinical Scenario:Thoracic outlet syndrome is quite challenging to diagnose. Currently, there are myriad diagnostic procedures used in the diagnosis of all types of thoracic outlet syndrome. However, controversy exists over which diagnostic procedures produce accurate findings.Clinical Question:Can clinical diagnostic tests accurately diagnose patients presenting with symptoms of thoracic outlet syndrome?Summary of Key Findings:A thorough literature search returned 6 possible studies; 3 studies met the inclusion criteria and were included. Two studies supported the use of clinical diagnostic tests for the diagnosis of thoracic outlet syndrome. One study reported high false-positive rates among clinical diagnostic tests for thoracic outlet syndrome. One study reported that clinical diagnostic test findings correlate to provocative positioned magnetic resonance imaging findings.Clinical Bottom Line:There is moderate evidence to support the use of the Halstead maneuver (also known as the costoclavicular maneuver or exaggerated military brace test), Wright’s test, Cyriax Release test, and supraclavicular pressure test to have good diagnostic accuracy for the provocation of symptoms in patients presenting with upper extremity pathology. However, these clinical diagnostic tests do not appear to allow for the differential diagnosis of thoracic outlet syndrome exclusively. The use of the Adson’s test and Roos test should be discontinued for the differential diagnosis of thoracic outlet syndrome.Strength of Recommendation:Grade B evidence exists to support the accuracy of the Halstead maneuver, Wright’s test, Cyriax Release test, and supraclavicular pressure test for the diagnosis of upper extremity pathology in general. Grade C evidence exists for the use of these clinical diagnostic tests to exclusively diagnose thoracic outlet syndrome.
Relative Risk Factors for Cardiac Erosion Following Transcatheter Closure of Atrial Septal Defects
Authors: McElhinney Doff B. , Quartermain Michael D. , Kenny Damien , Alboliras Ernerio , Amin Zahid 
Published: May 2016

Background—
Transcatheter closure of secundum atrial septal defects (ASD) using the Amplatzer septal occluder is generally safe and effective, but erosion into the pericardial space or aorta has been described. Although the absolute risk of this complication is low, there has been no assessment of relative risk factors.

Methods and Results—
All erosions reported to St. Jude Medical after ASD closure with an Amplatzer septal occluder (cases) were compared with controls (matched 2:1) who underwent ASD closure but did not develop an erosion. A total of 125 erosions were reported between 2002 and 2014, including 95 with an available echocardiogram. The median duration from implant to erosion was 14 days, but was >1 year in 16 patients. Nine patients (all age ≥17 years) who died were more likely to have an oversized device, and to have erosion into the aorta, than survivors. Aortic or superior vena cava rim deficiencies were more common in cases than in controls. In addition, larger balloon-sized ASD diameter, Amplatzer septal occluder device size, and device size–ASD diameter difference, and smaller weight:device size ratio were associated with erosion. On multivariable analysis, deficiency of any rim, device >5 mm larger than ASD diameter, and weight:device size ratio were associated with erosion.

Conclusions—
In addition to aortic rim deficiency, which was almost universal among erosion cases, there were several relative risk factors for erosion after ASD closure with the Amplatzer septal occluder device. To understand the mechanisms of and absolute risk factors for this uncommon but serious complication, an adequately powered prospective study with thorough echocardiographic evaluation will be critical.

Published: May 2016

Background—

The effect of a mutation in the bone morphogenetic protein receptor 2 (
BMPR2
) gene on right ventricular (RV) pressure overload in patients with pulmonary arterial hypertension is unknown. Therefore, we investigated RV function in patients who have pulmonary arterial hypertension with and without the
BMPR2
mutation by combining in vivo measurements with molecular and histological analysis of human RV and left ventricular tissue.

Methods and Results—

In total, 95 patients with idiopathic or familial pulmonary arterial hypertension were genetically screened for the presence of a
BMPR2
mutation: 28 patients had a
BMPR2
mutation, and 67 patients did not have a
BMPR2
mutation. In vivo measurements were assessed using right heart catheterization and cardiac MRI. Despite a similar mean pulmonary artery pressure (noncarriers 54±15 versus mutation carriers 55±9 mm Hg) and pulmonary vascular resistance (755 [483–1043] versus 931 [624–1311] dynes·s
−1
·cm
−5
), mutation carriers presented with a more severely compromised RV function (RV ejection fraction: 37.6±12.8% versus 29.0±9%:
P
<0.05; cardiac index 2.7±0.9 versus 2.2±0.4 L·min
−1
·m
−2
). Differences continued to exist after treatment. To investigate the role of transforming growth factor β and bone morphogenetic protein receptor II signaling, human RV and left ventricular tissue were studied in controls (n=6), mutation carriers (n=5), and noncarriers (n=11). However, transforming growth factor β and bone morphogenetic protein receptor II signaling, and hypertrophy, apoptosis, fibrosis, capillary density, inflammation, and cardiac metabolism, as well, were similar between mutation carriers and noncarriers.

Conclusions—
Despite a similar afterload, RV function is more severely affected in mutation carriers than in noncarriers. However, these differences cannot be explained by a differential transforming growth factor β, bone morphogenetic protein receptor II signaling, or cardiac adaptation.
Revision of Lithosia Fabricius, 1798 and Conilepia Hampson, 1900 (Lepidoptera, Arctiidae)

Published: May 2016

This paper deals with the revision of the Arctiidae genera Lithosia Fabricius, 1798 and Conilepia Hampson, 1900. Only two species currently are considered to be members of Lithosia, Lithosia quadra Linnaeus, 1758, and Lithosia yuennanensis Daniel, 1952. It is here proposed to consider the Far-Eastern populations of L. quadra as subspecies Lithosia quadra dives Butler, 1877, stat. rev. and the Transcaspian populations of the species are described here as Lithosia quadra ssp. soligena ssp. nov. The lectotype of Phalaena Noctua deplana Linnaeus, 1771, preserved in the Hunterian Museum of London, is designated. Two species, Lithosia subcosteola Druce, 1899 and Lithosia gynaegrapha de Joannis, 1930, are excluded from Lithosia. The rare and local Lithosia quadra sikkima Strand, 1922 is raised to species rank and transferred to Conilepia, comb. et stat. nov. The male of C. sikkima is described for the first time. Three species are considered to belong to the genus Conilepia, among them Conilepia cao sp. nov., which is described from Vietnam. All taxa are described and figured. A scenario for the faunogenesis of the Lithosia-Conilepia complex is proposed using molecular data.
Equilibration of a Baroclinic Planetary Atmosphere toward the Limit of Vanishing Bottom Friction
Authors: Chai Junyi , Jansen Malte , Vallis Geoffrey K. 
Published: May 2016

Abstract
This paper discusses whether and how a baroclinic atmosphere can equilibrate with very small bottom friction in a dry primitive equation general circulation model. The model is forced by a Newtonian relaxation of temperature to a prescribed temperature profile, and it is damped by a linear friction near the lower boundary. When friction is decreased by four orders of magnitude, kinetic energy dissipation by friction gradually becomes negligible, while “energy recycling” becomes dominant. In this limit kinetic energy is converted back into potential energy at the largest scales, thus closing the energy cycle without significant frictional dissipation. The momentum fluxes are of opposite sign in the upper and lower atmosphere: in the upper atmosphere, eddies converge momentum into the westerly jets; however, in the lower atmosphere, the eddies diverge momentum out of the westerly jets. The secondary circulation driven by the meridional eddy momentum fluxes thus acts to increase the baroclinicity of the westerly jet. This regime may be relevant for the Jovian atmosphere, where the frictional time scale may be much larger than the radiative damping time scale.
A Modified Interpolation Method for Surface Total Nitrogen in the Bohai Sea
Authors: Liu Yongzhi , Yu Jie , Shen Youli , Lv Xianqing 
Published: May 2016

AbstractA modified Cressman interpolation method (MCIM) is presented for the routine monitoring data of total nitrogen (TN) in the Bohai Sea to reduce interpolation errors by decreasing the influence radius and introducing background value. In twin experiments, two prescribed distributions are successfully estimated by MCIM with lower interpolation errors than the traditional Cressman interpolation method (TCIM) and the kriging method. In practical experiments, cross validation is applied to evaluate the interpolation results for four quarters in 2009 and 2010. Practical experimental results show that the interpolation results obtained with MCIM are greatly improved and can describe the spatial distribution characteristics of TN in the Bohai Sea with lower mean absolute error than the kriging method.

Are journal clubs useful in teaching psychiatry?
Authors: Swift Geraldine 
Published: May 2016

SummaryJournal clubs are a mandatory aspect of psychiatric training in the UK, yet are not always seen as a stimulating experience. Clarifying the aim of the club and tailoring it to the needs and wishes of the audience is an essential step. Teaching skills in critical appraisal is often seen as the main purpose of journal clubs. Depending on the audience, being able to formulate questions from clinical dilemmas, search the literature, and integrate research evidence, clinical expertise and the patient's needs and wishes may be as important. Linking these tasks in the journal club with routine clinical practice increases the chances of changing attitudes and behaviour and thus influencing care. New approaches to using social media and online formats mean that journal clubs are no longer restricted to a particular place or time, although the social aspect of meeting colleagues continues to be important for many.
Tourette syndrome in children and adolescents: aetiology, presentation and treatment
Authors: Robertson Mary May 
Published: May 2016

SummaryTourette syndrome is a complex neuropsychiatric disorder of juvenile onset, characterised by motor and phonic tics. It is associated with a number of comorbid psychiatric conditions and a reduced quality of life in the young person and with parenting stress, caregiver burden and psychopathology in the parents. The global prevalence (about 1%) is higher than previously thought, with a strong male preponderance. Evidence is emerging that Tourette syndrome is not a unified disorder; rather, it encompasses a number of subtypes, characterised by complexity of tics and the simultaneous presence of other behaviours or disorders. This article discusses the aetiology of the syndrome, and examines its clinical features and comorbid psychiatric conditions and psychopathologies. Assessment and diagnosis are also discussed. Psychoeducation is a cornerstone of management, augmented with behavioural and/or pharmacological treatments. Newer therapies, such as deep brain stimulation, offer tantalising possibilities, but further research is still needed.
Drug treatment of autism spectrum disorder and its comorbidities in children and adolescents
Authors: Santosh Paramala J. , Singh Jatinder 
Published: May 2016

SummaryAutism spectrum disorder (ASD) is a complex, multifactorial disorder, the prevalence of which is rising. Specific biomarkers are yet to be identified for the classic ASD phenotypes, so despite treatment advances, most interventions focus on the comorbid disorders of ASD and have little impact on the underlying pathogenesis of the disorder. This article describes drug treatments that target the core symptoms of ASD and its comorbid conditions in children and adolescents. Difficulties and challenges encountered when treating the most frequent comorbidities are discussed, with emphasis on the safety, tolerability and efficacy of medications. In view of its widespread use, complementary and alternative medicine is also described.
Managerial Ability and Credit Risk Assessment
Authors: Bonsall Samuel B. , Holzman Eric R. , Miller Brian P. 
Published: May 2016

Research on the credit rating process has primarily focused on how rating agencies incorporate firm characteristics into their rating opinions. We contribute to this literature by examining the impact of managerial ability on the credit rating process. Given debt market participants’ interest in assessing default risk, we begin by documenting that higher managerial ability is associated with lower variability in future earnings and stock returns. We then show that higher managerial ability is associated with higher credit ratings (i.e., lower assessments of credit risk). To provide more direct identification of the impact of managerial ability, we examine chief executive officer (CEO) replacements and document that ratings increase (decrease) when CEOs are replaced with more (less) able CEOs. Finally, we show that managerial ability also has capital market implications by documenting that managerial ability is associated with bond offering credit spreads. Collectively, our evidence suggests that managerial ability is an important factor that bond market participants impound into their assessments of firm credit risk.

Are Professional Investment Managers Skilled? Evidence from Syndicated Loan Portfolios
Authors: Liebscher Roberto , Mählmann Thomas 
Published: May 2016

Theory predicts that individual investor’s incentives to uncover new information about asset values are low if asset prices are efficient. This, in turn, implies that heterogeneity in investment manager skill, if present, should be most clearly visible among managers that focus on asset classes with less informationally efficient prices. We investigate this argument using a large sample of syndicated bank loan portfolios managed by collateralized loan obligation (CLO) managers. Using a CLO’s equity tranche cash-on-cash return to measure performance, we find strong persistence that is robust to an extensive set of risk controls. Although investors seem to derive their expectation about management quality from a manager’s realized performance and allocate more capital to “skilled” managers, top performers cope to stay ahead of net-of-fees. This questions the rationality of managers and the efficiency of the syndicated loan market. This paper was accepted by Wei Jiang, finance.
Ants in Burned and Unburned Areas in Campos Rupestres Ecosystem
Authors: Neves Frederico De Siqueira , Lana Tate C. , Anjos Marina C. , Reis Ariel C. , Fernandes G. Wilson 
Published: May 2016

Ground-dwelling ants have shown consistent resilience to fire in savanna environments. We carried out a study to investigate how ant community structure responds to fire in a harsh and fragile Cerrado ecosystem, the campos rupestres. We studied the change in the ant communities on a local scale subjected to fire in two rocky outcrop habitats at two different elevations (800m above sea level and 1300m a.s.l.). Pitfall trap samples were set at three different periods after a fire event: one, four, and ten months later. Overall, one hundred and fifteen ant species were collected. On a local scale, at the altitude of 800 m asl, no difference in richness and composition of the ant community was found between burned and control plots, whereas at 1300 m asl the burned areas showed higher richness and different ant composition in comparison to control areas. Differences were clear in the rainy period, four months after the fire. Ten months later, no difference between the richness of ant species in burned and unburned plots was found at higher altitudes, even though the plots showed distinct species composition. These data support the hypothesis that fire must be a structuring disturbance factor for some groups in the ant assemblages and indicate that ant community structure at higher elevations is somehow influenced by the recover of the campos rupestre vegetation.
Analysis of a Navier–Stokes–Darcy coupling problem
Authors: Mabrouki Yassine , Satouri Jamil 
Published: May 2016

AbstractThe aim of this work is to present a model for coupling the Darcy equations in a porous medium with the Navier–Stokes equations in the cracks. We consider a two- or three-dimensional domain with non-standard condition at the interface, namely the continuity of the pressure. We propose a mixed formulation and establish the existence of a solution for the coupled problem.
Free light chain testing for the diagnosis, monitoring and prognostication of AL amyloidosis
Authors: Mollee Peter , Merlini Giampaolo 
Published: May 2016

AbstractThe disease causing agent in systemic AL amyloidosis is a monoclonal immunoglobulin free light chain, or fragments thereof, circulating in the blood. It is not surprising, therefore, that measurement of serum free light chains plays a central role in the management of this disorder. In this paper, we review the utility of the serum free light chain assay in the investigation, prognostication and monitoring of AL amyloidosis. Data on the two currently available commercial assays is compared and some practical applications of the assay’s use are presented. While there are limitations, it is clear that the availability of the free light chain assay in the laboratory is a major advance and plays an essential role in the management of patients with AL amyloidosis.

When are Zariski chambers numerically determined?
Authors: Rams Sławomir , Szemberg Tomasz 
Published: May 2016

Abstract
The big cone of every smooth projective surface X admits a natural
decomposition into Zariski chambers. The purpose of this note is to give a simple criterion for
the interiors of all Zariski chambers on X to be numerically determined Weyl
chambers. Such a criterion generalizes the results of Bauer–Funke [4] on K3 surfaces to arbitrary smooth projective surfaces.
In the last section, we study the relation between decompositions of the big cone and elliptic fibrations on some surfaces.
