New taxonomic combinations in West Indian Ocean Vanguerieae (Rubiaceae)
Authors: KAINULAINEN KENT , RAZAFIMANDIMBISON SYLVAIN G.
Published: November 2016

This paper provides new combinations for two species endemic to the Seychelles, Canthium carinatum and C. sechellarum, which are transferred to Peponidium (tribe Vanguerieae, Ixoroideae, Rubiaceae), as supported by recent molecular phylogenetic analyses. Several new combinations in Vanguerieae from Madagascar are also proposed, based on morphological studies. Canthium bakerianum and C. homolleanum are transferred to Peponidium, whereas C. andringitrense, C. mandrarense, and Peponidium montana are transferred to Pyrostria. The names Pyrostria angustifolia, P. media, and P. major, previously invalid, are here validly published.
Ophiostoma olgensis, a new species associated with Larix spp. and Ips subelongatus in northern China

Published: November 2016

A new ophiostomatoid species, Ophiostoma olgensis sp. nov., isolated from Larix olgensis and Larix gmelini infested by Ips subelongatus in northern China, is described and illustrated. The fungus produces abundant short-necked perithecia in phloem as well as on artificial substrates. The short-necked perithecia are characteristic of the Ophiostoma minus complex and more specifically, of Ophiostoma kryptum, isolated from European larch. However, O. olgensis can be distinguished from O. kryptum on the basis of combined morphological traits and phylogenetic data from ITS, partial β-tubulin, EF-1α, and actin gene region analyses of single-spore isolates. The most obvious morphological differences between both species are the asexual forms and the conidial morphology. The pathogenicity of O. olgensis and O. kryptum was evaluated in situ on local mature Larix spp. by stem inoculation. All inoculations of O. olgensis and O. kryptum resulted in serious lesions on the inner bark, and thus the new species is considered to be a pathogen on Larix spp. (L. olgensis, L. gmelini, L. principis-rupprechtii and L. kaempferi ).

Published: November 2016

Based on field investigations, morphological and molecular systematic studies, a new species, Caltha dysosmoides (Ranunculaceae) from southwestern China is described. It differs from all other known congeneric species by the densely dentate leaf margin, the pendulous pedicels, the scarlet flowers, the compressed filaments, and the triangular connective. To better understand taxonomy of this new species, phylogenetic analyses were conducted using a combined dataset from nrITS, plastid trnL-trnF region, and atpB-rbcL spacer. The results indicate that Caltha is monophyletic and C. dysosmoides is sister to C. sinogracilis. The conservation status of the new species is categorized as CR based on IUCN criteria.
Synopsis of Himatanthus (Apocynaceae, Rauvolfiodieae: Plumerieae) species from Peru
Authors: AMASIFUEN GUERRA CARLOS A. , DELPRETE PIERO G. , SPINA ANDREA P.
Published: November 2016

The delimitation of Himatanthus (Apocynaceae) species has long been problematic, and much confusion remains as to which names and species delimitations should be adopted. In order to recognize and clarify the species of Himatanthus occurring in Peru, herbarium specimens were examined, coupled with detailed field observations. The present study recognizes three species in Peru: H. revolutus, H. tarapotensis and H. phagedaenicus. A key to identify the species, as well as descriptions, synonymy, specimens cited, and taxonomic comments are presented.

Authors: EKANAYAKA ANUSHA H. , ZHAO QI , JONES GARETH E.B. , PU EN-DA , HYDE KEVIN D.
Published: November 2016

Acervus is a small genus in Pyronemataceae. Most of the species in this genus have been recorded from China. In the present study, two species of Acervus from Yunnan Province, in southwestern China, were investigated by using morphology and DNA sequence data. This paper introduces two new species A. stipitatus and A. globulosus, with morphological descriptions, and compares them with morphologically similar taxa. Multi-gene phylogenetic analyses inferred from 28S, TEF1 and RPB2 sequence data strongly support the lineages for taxa of Acervus, corresponding to morphological features. We also provide a summarized comparison of the important morphological characteristics of Acervus species.
Revision of the genera Pareuthria Strebel, 1905, Glypteuthria Strebel, 1905 and Meteuthria Thiele, 1912 (Gastropoda: Buccinulidae) with the description of three new genera and two new species from Southwestern Atlantic waters
Authors: PASTORINO GUIDO
Published: November 2016

This revision of the buccinulid genera Pareuthria Strebel, 1905, Glypteuthria Strebel, 1905 and Meteuthria Thiele, 1912 includes all the reported nominal species and type specimens. A total of 13 valid species included in six genera are described and illustrated. All but one –P. fuscata– live in shallow waters around the Magellanic region and even reach lower latitudes including deeper waters off the Buenos Aires province. The genus Pareuthria includes P. fuscata (Bruguière, 1789), P. atrata (E. A. Smith, 1881) for which a lectotype is designated, and P. venustula Powell, 1951. P. fuscata is also confirmed to occur in New Zealand waters. Glypteuthria Strebel, 1905 includes only the type species G. meridionalis (E.A. Smith, 1881). Two species are included in the genus Meteuthria Thiele, 1912, the type species M. martensi (Strebel, 1905), for which a lectotype is designated, and M. batialis n. sp., which is described herein based on specimens from deep water off Buenos Aires province. Three new genera are described: Falsimacme n. gen. to include only the type species F. kobelti (Strebel, 1905) (formerly in the genus Meteuthria); Argeneuthria n. gen. to include A. cerealis (Rochebrune & Mabille, 1885), A. paessleri (Strebel, 1905), A. euthrioides (Melvill & Standen, 1898), A. philippii (Strebel, 1905) and A. varicosa new species; and Microdeuthria n. gen. to include only M. michaelseni (Strebel, 1905). In addition, “Anomacme” multituberculata Castellanos, Rolán & Bartolotta, 1987 included by Dell (1990) in Meteuthria is excluded from the latter genus based on the morphology of the radula.

Asian pheretimoid earthworms in North America north of Mexico: An illustrated key to the genera Amynthas, Metaphire, Pithemera, and Polypheretima (Clitellata: Megascolecidae)
Authors: CHANG CHIH-HAN , SNYDER BRUCE A. , SZLAVECZ KATALIN
Published: November 2016

The invasion of the pheretimoid earthworms in North America, especially the genera Amynthas and Metaphire, has raised increasing concerns among ecologists and land managers, in turn increasing the need for proper identification. However, the commonly used keys to this group are more than 30 years old with outdated taxonomic information and are based primarily on internal morphology. The requirement of significant amount of taxonomic expertise and dissection, even from the first entry of the key, has prevented broader use of these keys. As a result, many publications in the United States have used Amynthas spp. to represent the group without identifying the species. We present here a new key and diagnoses for the 16 pheretimoid earthworm species recorded in North America north of Mexico, including four genera: Amynthas (10), Metaphire (4), Pithemera (1), and Polypheretima (1). The descriptions were based on published records with modifications following inspection of specimens archived at the National Museum of Natural History, Smithsonian Institution, Washington, D.C. Photos of external and internal characters, including male pores, spermathecal pores, genital markings, spermathecae, prostate glands, and intestinal caeca, are presented to help identification. A summary of current knowledge about the ecology and historical context is provided for each species. We also highlight the previously overlooked and potentially common and widespread co-occurrence of three species—A. agrestis, A. tokioensis, and M. hilgendorfi—and point out that many recent claims of invasion of A. agrestis need to be re-evaluated for potential misidentification.
Phasmarhabditis bonaquaense n. sp. (Nematoda: Rhabditidae), a new slug-parasitic nematode from the Czech Republic
Authors: NERMUŤ JIŘÍ , PŮŽA VLADIMÍR , MEKETE TESFAMARIAM , MRÁČEK ZDENĚK
Published: November 2016

Phasmarhabditis bonaquaense n. sp. is described and illustrated from the body of Malacolimax tenellus, from the locality of České Švýcary near the village of Dobrá Voda, the Czech Republic. Females are characterized by a body length of 2349 (1878–2626) µm and a cupola shaped tail with a long hyaline hair-like tail tip. Extremely prominent papilla-like phasmids present. Males 1829 (1414–2121) µm long. Peloderan bursa with nine pairs of rays (papillae), 1/1/1/2/1/3. One non-paired apparent papilla-like structure located near the ventral appendage anterior to the cloaca. Prominent papilla-like phasmids located close to the tail tip. Small subunit (18S), ITS, and D2-D3 expansion segments of the large subunit of ribosomal DNA were used to analyze the phylogenetic relationships of sequenced species in the genus Phasmarhabditis and other closely related species. Phasmarhabditis bonaquaense n. sp. varied from other related nematodes both in morphological characterizations and phylogenetic analysis. The life cycle of the newly described species is not well known but it is probably a facultative, mollusc-parasitic nematode able to survive permanently in the saprobic phase on decaying organic matter.

Published: November 2016

The 22 Sri Lankan representatives of the family Platystictidae, all endemic to the island and belonging to the distinct endemic subfamily Platystictinae, are revised, and a new reconstruction of the phylogeny based on molecular characters is provided. Five new species are described: Ceylonosticta venusta sp. nov. (holotype ♂: Rambodde Falls, at the tunnel; Nuwara Eliya District, Central Province; N7.0489, E80.6961; 12-vii-2012; to be deposited at National Museum of Natural History, Colombo, Sri Lanka), C. inferioreducta sp. nov. (holotype ♂: Norton Bridge, stream on the B43 road 1.5km WNW of Norton Bridge; Nuwara Eliya District, Central Province; N6.9171, E80.5075; 28-vii-2009; to be deposited at National Museum of Natural History, Colombo, Sri Lanka), C. mirifica sp. nov. (holotype ♂: Uwella, primary forest on the road Uwella-Ratnapura, 11.5km NW of Balangoda; Ratnapura District, Sabaragamuwa Province; N6.6968, E80.6059; 16-vii-2012; to be deposited at National Museum of Natural History, Colombo, Sri Lanka), Platysticta secreta sp. nov. (holotype ♂: Hasalaka; Kandy District, Central Province; N7.3535, E80.9509; 31-v-1975; deposited at National Museum of Natural History, Smithsonian Institution, Washington, USA) and P. serendibica sp. nov. (holotype ♂: Kanneliya; Galle District, Southern Province; N6.2291, E80.3834; 8 & 9-vi-1975; deposited at National Museum of Natural History, Smithsonian Institution, Washington, USA). Additionally, a determination key, figures showing morphological details and coloration in life, as well as distribution maps for all species are presented. Based on molecular analysis of 21 taxa, the phylogeny of Platystictinae is presented and discussed from the zoogeographical and paleogeographical point of view. Sri Lankan species, traditionally placed in the genera Platysticta Selys and Drepanosticta Laidlaw / Ceylonosticta Fraser, separated into distinct clades within the subfamily as presently defined, but the monophyletic nature of the Platystictinae and its Sri Lankan endemicity is confirmed. For the South Indian species, formerly known as Platysticta deccanensis, morphological and molecular analyses demonstrated that it does not belong to the Sri Lankan clade and a new genus Indosticta gen. nov. is erected to accommodate it.
Taxonomic revision of Stagmatoptera Burmeister, 1838 (Mantodea: Mantidae, Stagmatopterinae)
Authors: RODRIGUES HENRIQUE MIRANDA , CANCELLO ELIANA MARQUES
Published: November 2016

Stagmatoptera Burmeister, 1838 includes medium to large-sized (49.8–98.7mm) praying mantises distributed in the Neotropical region. They are characterized for having a central, circular spot on each forewing, and 2–4 carinae in the head’s frontal shield. This study is an updated revision of the genus on the basis of type and non-type material deposited in various scientific collections from Europe and the Americas. The following nomenclatural procedures were conducted: Stagmatoptera nova is a new junior synonym of Stagmatoptera pia, Stagmatoptera ignota as the junior synonym of Stagmatoptera femoralis, and Stagmatoptera flavipennis is reinstated as the junior synonym of Stagmatoptera supplicaria. Two new species are described: Stagmatoptera diana Rodrigues sp. n. from Colombia and Venezuela, and Stagmatoptera cerdai Rodrigues sp. n. from Trinidad & Tobago and Venezuela. Stagmatoptera now includes 14 species, two of which (Stagmatoptera abdominalis and Stagmatoptera indicator) are considered as species inquirenda. We provide detailed morphological descriptions of all species, a species-level identification key, in addition to abundant visual material to assist identification. Female genitalia, a structure seldom used for taxonomic purposes, was a useful character system to distinguish among species of the genus. Distribution maps for all species are also provided.
Seasonally Resolved Distributional Trends of North American Temperatures Show Contraction of Winter Variability
Authors: Rhines Andrew , McKinnon Karen A. , Tingley Martin P. , Huybers Peter
Published: November 2016

There is considerable interest in determining whether recent changes in the temperature distribution extend beyond simple shifts in the mean. The authors present a framework based on quantile regression, wherein trends are estimated across percentiles. Pointwise trends from surface station observations are mapped into continuous spatial fields using thin-plate spline regression. This procedure allows for resolving spatial dependence of distributional trends, providing uncertainty estimates that account for spatial covariance and varying station density. The method is applied to seasonal near-surface temperatures between 1979 and 2014 to unambiguously assess distributional changes in the densely sampled North American region. Strong seasonal differences are found, with summer trends exhibiting significant warming throughout the domain with little distributional dependence, while the spatial distribution of spring and fall trends show a dipole structure. In contrast, the spread between the 95th and 5th percentile in winter has decreased, with trends of −0.71° and −0.85°C decade−1, respectively, for daily maximum and minimum temperature, a contraction that is statistically significant over 84% of the domain. This decrease in variability is dominated by warming of the coldest days, which has outpaced the median trend by approximately a factor of 4. Identical analyses using ERA-Interim and NCEP-2 yield consistent estimates for winter (though not for other seasons), suggesting that reanalyses can be reliably used for relating winter trends to circulation anomalies. These results are consistent with Arctic-amplified warming being strongest in winter and with the influence of synoptic-scale advection on winter temperatures. Maps for all percentiles, seasons, and datasets are provided via an online tool.
Response of the North Pacific Tropical Cyclone Climatology to Global Warming: Application of Dynamical Downscaling to CMIP5 Models
Authors: Zhang Lei , Karnauskas Kristopher B. , Donnelly Jeffrey P. , Emanuel Kerry
Published: November 2016

A downscaling approach is applied to future projection simulations from four CMIP5 global climate models to investigate the response of the tropical cyclone (TC) climatology over the North Pacific basin to global warming. Under the influence of the anthropogenic rise in greenhouse gases, TC-track density, power dissipation, and TC genesis exhibit robust increasing trends over the North Pacific, especially over the central subtropical Pacific region. The increase in North Pacific TCs is primarily manifested as increases in the intense and relatively weak TCs. Examination of storm duration also reveals that TCs over the North Pacific have longer lifetimes under global warming.

Through a genesis potential index, the mechanistic contributions of various physical climate factors to the simulated change in TC genesis are explored. More frequent TC genesis under global warming is mostly attributable to the smaller vertical wind shear and greater potential intensity (primarily due to higher sea surface temperature). In contrast, the effect of the saturation deficit of the free troposphere tends to suppress TC genesis, and the change in large-scale vorticity plays a negligible role.

Negotiating the UK's Post-Brexit Trade Arrangements
Authors: Holmes Peter , Rollo Jim , Winters L. Alan
Published: November 2016

This paper considers the agenda for UK trade negotiations over the post-Brexit period. There are several groups of countries that will need to be dealt with and we consider the priorities among them. Negotiations with the WTO and the EU are the most important and the most pressing in time, and should be pursued simultaneously. On the former, the UK must try quickly to establish its independent WTO status, which will be greatly facilitated by minimising the changes it proposes to its tariffs schedules. On the EU the UK needs to consider the choices between remaining in the customs union, creating an FTA with the EU and maintaining the ‘regulatory union’ that is the European Economic Area (EEA). Only when relations with the EU and WTO are clear will it be feasible to negotiate trade deals of various sorts with other countries, ranging from those with which we already have deals via the EU to those that currently trade with us on ‘WTO rules’. All of this takes time and we argue that it may be worth pursuing transitional arrangements to extend certain current trading arrangements a few years beyond Brexit in order to make time for serious negotiations.
Assessing the Impact of Trade Agreements on Trade
Authors: Ebell Monique
Published: November 2016

One of the key issues facing the UK in the wake of the advisory referendum result to leave the European Union is the precise nature of its relationship with the European Union. At one extreme would be continued membership in the European Economic Area, including membership in the single market. Other options would be either no free trade agreement (FTA) with the EU at all or a less comprehensive FTA which stops short of single market membership. This paper compares the ability of EEA membership and less comprehensive FTAs to generate trade in goods and services. We investigate this question using empirical gravity model methodology and the most recent available data from 42 countries. We use recently developed econometric methods to deal with observations of zero trade flows and issues connected with endogeneity. The main finding is that while EEA membership is associated with substantial and statistically significant increases in bilateral services trade flows, membership in less comprehensive FTAs is not associated with any significant increase in bilateral services trade. For goods, EEA membership is associated with larger bilateral trade flows than are less comprehensive FTAs. These results suggest that it might be difficult to replace, on an exit from a European Union, lost trade flows with the EU by means of shallower FTAs with the EU or with third countries.
Mindfulness in addictions
Authors: Johnson David , Mullen Donna , Smith Iain D. , Wilson Alistair
Published: November 2016

There have been many developments in mindfulness-based approaches (MBAs) since the original mindfulness-based stress reduction (MBSR) course was first delivered in the 1980s. There are now a variety of mindfulness approaches, which are used to good effect in a range of psychological and physical health disorders. The addictions field first witnessed the development of relapse prevention techniques more than 30 years ago. MBAs have been adapted for use in relapse prevention and can be offered as a mindfulness-based relapse prevention (MBRP) course. MBSR or mindfulness-based cognitive therapy (MBCT) courses may also be useful for those with addiction problems. In this article, we describe the MBAs that are commonly offered at present. We highlight ways in which these approaches may be useful in the addictions feld. We also make suggestions for clinicians who may be interested in offering MBAs within their own service.
Perinatal psychiatry: a new specialty or everyone's business?
Authors: Humphreys Jacqueline , Obeney-Williams Janet , Cheung Rachael W. , Shah Nisha
Published: November 2016

Perinatal psychiatry is a relatively new subspecialty and controversy exists about such specialist provision. Differences can occur in how mental illnesses present in pregnancy, and there is a need to take into account both mother and baby. The risks of not treating perinatal mental illness can be both acute and chronic, and suicide in the context of untreated illness remains a leading indirect cause of maternal mortality. Despite the government's agenda of preventive healthcare, service provision is inequitable across the UK. Advice regarding treatment continues to be complex, and perinatal psychiatrists need to keep abreast of a growing evidence base. This review offers an overview of some current issues in the care of patients in the perinatal period and shows how specialised perinatal services are uniquely placed to meet their needs. Hopefully, it will prove useful to all clinicians responsible for the perinatal care of women and their families.
The Significance of Linguistic Variation in the Speeches of Rev. Dr. Martin Luther King Jr.
Authors: Wolfram Walt , Myrick Caroline , Forrest Jon , Fox Michael J.
Published: November 2016

Although Rev. Dr. Martin Luther King Jr.'s eloquence as a speaker is widely recognized and his rhetorical strategies have been extensively studied, no analyses have been conducted on his language variation in different speech settings. This article examines a set of variable structures in King's speech to determine how it indexes his regional, social, and ethnic identity as he accommodated different audiences and interactions. The use of unstressed (ING), medial and final /t/ release, postvocalic nonrhoticity, coda-final cluster reduction, copula/auxiliary absence, the vowel system, and syllable timing are considered for four different speech events: the “I Have a Dream” speech (1963), the Nobel Prize acceptance speech (1964), a conversation with talk-show host Merv Griffin (1967), and the “I've Been to the Mountaintop” speech (1968). The analysis indicates stability across speech events for some variables and significant variation for others based on the speech event. His indexical profile indicates that he consistently embodied his Southern-based, African American preacherly stance while fluidly shifting features that indexed performance and formality based on audience, interaction, and intentional purpose. His language embraced ethnolinguistic tradition and transcended linguistic diversity, modeling linguistic equality in practice.
Do Consumers Exploit Commitment Opportunities? Evidence from Natural Experiments Involving Liquor Consumption
Authors: Bernheim B. Douglas , Meer Jonathan , Novarro Neva K.
Published: November 2016

This paper provides evidence concerning the extent to which consumers of liquor employ commitment devices. One widely recommended commitment strategy is to regulate alcohol consumption by deliberately manipulating availability. The paper assesses the prevalence of the “availability strategy” by evaluating the effects of policies that would influence its effectiveness—specifically, changes in allowable Sunday sales hours. It finds that consumers increase their liquor consumption in response to extended Sunday on-premises sales hours, but not in response to extended off-premises sales hours. The latter finding is inconsistent with widespread use of the availability strategy. (JEL D12, H75, K39, L66)
Resource Constraints and the Criminal Justice System: Evidence from Judicial Vacancies
Authors: Yang Crystal S.
Published: November 2016

Ten percent of federal judgeships are currently vacant, yet little is known on the impact of these vacancies on criminal justice outcomes. Using judge deaths and pension eligibility as instruments for vacancies, I find that prosecutors dismiss more cases during vacancies. Prosecuted defendants are more likely to plead guilty and less likely to be incarcerated during vacancies, with defendants who are detained pretrial more likely to be incarcerated. The current rate of vacancies has resulted in 1,000 fewer prison inmates annually compared to a fully-staffed court system, a 1.5 percent decrease. (JEL K14, K41, K42)
Research Commentary—Diversity of the Information Systems Research Field: A Journal Governance Perspective
Authors: Burgess Thomas F. , Grimshaw Paul , Shaw Nicky E.
Published: November 2016

Diversity has attracted much attention within the information systems (IS) field, with literature concentrating on diversity in topics and methods. These constitute two of three identified areas of research field diversity; the little-investigated third area includes demographic and social diversity of researchers. This study explores this gap for researchers comprising the editorial advisory boards (EABs) of 52 IS journals and links the underexplored types of diversity to topic diversity. The journals are categorized into seven intellectual communities, using topic affinity of journal content, and a social network of EAB members constructed from board interlocks. The network structure appears to reflect the topic-based community links. Journal communities are aggregated into two components of the social network: a business-school-related core set of journals and a more diverse computing- and engineering-related periphery. The strong ties at the network center do not necessarily reflect journal status. The observed combination of focus and diversity is consistent with a polycentric view of the IS field. Findings suggest low demographic diversity in the field and that demographic diversity correlates with other types of diversity. The field’s separation into business core and computing periphery is highlighted as potentially challenging to the IS field’s identity.
Characterizations of Smooth Ambiguity Based on Continuous and Discrete Data
Authors: Minardi Stefania , Savochkin Andrei
Published: November 2016

In the Anscombe-Aumann setup, we provide conditions for a collection of observations to be consistent with a well-known class of smooth ambiguity preferences (Klibanoff P, Marinacci M, Mukerji S (2005) A smooth model of decision making under ambiguity. Econometrica 73(6):1849–1892.). Each observation is assumed to take the form of an equivalence between an uncertain act and a certain outcome. We provide three results that describe these conditions for data sets of different cardinality. Our findings uncover surprising links between the smooth ambiguity model and classic mathematical results in complex and functional analysis.
A Polyhedral Study of Binary Polynomial Programs
Authors: Del Pia Alberto , Khajavirad Aida
Published: November 2016

We study the polyhedral convex hull of a mixed-integer set 𝒮 defined by a collection of multilinear equations over the unit hypercube. Such sets appear frequently in the factorable reformulation of mixed-integer nonlinear optimization problems. In particular, the set 𝒮 represents the feasible region of a linearized unconstrained binary polynomial optimization problem. We define an equivalent hypergraph representation of the mixed-integer set 𝒮, which enables us to derive several families of facet-defining inequalities, structural properties, and lifting operations for its convex hull in the space of the original variables. Our theoretical developments extend several well-known results from the Boolean quadric polytope and the cut polytope literature, paving a way for devising novel optimization algorithms for nonconvex problems containing multilinear sub-expressions.

Effective route planning for battery electric commercial vehicle (ECV) fleets has to take into account their limited autonomy and the possibility of visiting recharging stations during the course of a route. In this paper, we consider four variants of the electric vehicle-routing problem with time windows: (i) at most a single recharge per route is allowed, and batteries are fully recharged on visit of a recharging station; (ii) multiple recharges per route, full recharges only; (iii) at most a single recharge per route, and partial battery recharges are possible; and (iv) multiple, partial recharges. For each variant, we present exact branch-price-and-cut algorithms that rely on customized monodirectional and bidirectional labeling algorithms for generating feasible vehicle routes. In computational studies, we find that all four variants are solvable for instances with up to 100 customers and 21 recharging stations. This success can be attributed to the tailored resource extension functions (REFs) that enable efficient labeling with constant time feasibility checking and strong dominance rules, even if these REFs are intricate and rather elaborate to derive. The studies also highlight the superiority of the bidirectional labeling algorithms compared to the monodirectional ones. Finally, we find that allowing multiple as well as partial recharges both help to reduce routing costs and the number of employed vehicles in comparison to the variants with single and with full recharges.

Aims

The aim of this consensus was to develop a definition of post-operative fibrosis of the knee.

Patients and Methods

An international panel of experts took part in a formal consensus process composed of a discussion phase and three Delphi rounds.

Results

Post-operative fibrosis of the knee was defined as a limited range of movement (ROM) in flexion and/or extension, that is not attributable to an osseous or prosthetic block to movement from malaligned, malpositioned or incorrectly sized components, metal hardware, ligament reconstruction, infection (septic arthritis), pain, chronic regional pain syndrome (CRPS) or other specific causes, but due to soft-tissue fibrosis that was not present pre-operatively. Limitation of movement was graded as mild, moderate or severe according to the range of flexion (90° to 100°, 70° to 89°, < 70°) or extension deficit (5° to 10°, 11° to 20°, > 20°). Recommended investigations to support the diagnosis and a strategy for its management were also agreed.

Conclusion

The development of standardised, accepted criteria for the diagnosis, classification and grading of the severity of post-operative fibrosis of the knee will facilitate the identification of patients for inclusion in clinical trials, the development of clinical guidelines, and eventually help to inform the management of this difficult condition.

A protocol for the use of closed reduction in children with developmental dysplasia of the hip incorporating open psoas and adductor releases and a short-leg cast
Authors: Tennant S. J. , Eastwood D. M. , Calder P. , Hashemi-Nejad A. , Catterall A.
Published: November 2016

Aims

Our aim was to assess the effectiveness of a protocol involving a standardised closed reduction for the treatment of children with developmental dysplasia of the hip (DDH) in maintaining reduction and to report the mid-term results.

Methods

A total of 133 hips in 120 children aged less than two years who underwent closed reduction, with a minimum follow-up of five years or until subsequent surgery, were included in the study. The protocol defines the criteria for an acceptable reduction and the indications for a concomitant soft-tissue release. All children were immobilised in a short- leg cast for three months. Arthrograms were undertaken at the time of closed reduction and six weeks later. Follow-up radiographs were taken at six months and one, two and five years later and at the latest follow-up. The Tönnis grade, acetabular index, Severin grade and signs of osteonecrosis were recorded.

Results

A total of 67 hips (51%) were Tönnis grade 3/4 hips. By 12 months, 20 reductions (15%) had not been maintained, and these required open reduction. In all, 55% of these were Severin 1; the others were Severin 2, due to minor acetabular dysplasia. Of the 113 successful closed reductions, 98 hips (87%) were Severin 1. Surgery for residual DDH was offered for ten hips. Osteonecrosis was seen in 32 hips (29%) but was transient in 28. In total, two children (1.5%) had severe osteonecrosis. Bilateral dislocations were significantly more likely to fail and most Tönnis 4 hips failed.

Conclusion

Closed reduction, with concomitant adductor and psoas release when required and the use of a short leg plaster of Paris cast for three months, can produce good mid-term results in children with DDH aged less than two years. This protocol is not recommended for Tönnis 4 hips. Cite this article: Bone Joint J 2016;98-B:1548–53.

Published: November 2016

Aims

Diabetes mellitus is the most common co-morbidity associated with necrotising fasciitis. This study aims to compare the clinical presentation, investigations, Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) score, microbiology and outcome of management of this condition in diabetic and non-diabetic patients.

Patients and Methods

The medical records of all patients with surgically proven necrotising fasciitis treated at our institution between 2005 and 2014 were reviewed. Diagnosis of necrotising fasciitis was made on findings of ‘dishwater’ fluid, presence of greyish necrotic deep fascia and lack of bleeding on muscle dissection found intra-operatively. Information on patients’ demographics, presenting symptoms, clinical signs, investigations, treatment and outcome were recorded and analysed.

Results

A total of 127 patients with surgically proven necrotising fasciitis were included in this study. In all, 78 (61.4%) were diabetic and 49 (38.6%) were non-diabetic. Diabetics tended to have polymicrobial infections (p = 0.03), renal impairment (p < 0.001), end-stage renal disease (p = 0.001) and multiple co-morbidities (p < 0.001). They presented atypically, with less tenderness (p = 0.042) and less hypotension (p = 0.034). This resulted in higher rates of misdiagnosis (p = 0.038) and a longer time to surgery (p = 0.05) leading to longer hospital stays (p = 0.043) and higher rates of amputation (p = 0.045). However, the rate of mortality is comparable (p = 0.525). A LRINEC score of > 8 appears to be more sensitive in diabetic patients (p < 0.001). However, the increased sensitivity in diabetic patients may be related to hyperglycemia and electrolyte abnormalities associated with renal impairment in these patients.

Conclusion

The LRINEC score must be used with caution in diagnosing necrotising fasciitis in diabetic patients. A high index of suspicion is key to the early diagnosis and subsequent management of these patients. Cite this article: Bone Joint J 2016;98-B:1563–8.
Comparison of measurements of the glenopolar angle in 3D CT reconstructions of the scapula and 2D plain radiographic views
Authors: Suter T. , Henninger H. B. , Zhang Y. , Wylie J. D. , Tashjian R. Z.
Published: November 2016

Aims

The aim of this study was to analyse the effect of altered viewing perspectives on the measurement of the glenopolar angle (GPA) and the differences between these measurements made on 3D CT reconstructions and anteroposterior (AP) scapular view radiographs.

Materials and Methods

The influence of the viewing perspective on the GPA was assessed, as were the differences in the measurements of the GPA between 3D CT reconstructions and AP scapular view radiographs in 68 cadaveric scapulae.

Results

The median GPA in 3D reconstructions and AP scapular views were 42.7° (95% confidence intervals (CI), 42.0° to 43.5°) and 41.3° (95% CI 40.4° to 42.0°) respectively (p < 0.001). All but five of 20 malpositions demonstrated a significant difference in GPA compared with the respective AP scapular view (p ≤ 0.005). The GPA was most susceptible to malposition in retroversion/anteversion. Inter- and intra-observer reliability for all measurements of the GPA was excellent for 3D CT reconstructions (intraclass correlation (ICC) 0.93 (95% CI 0.87 to 0.96) and 0.94 (95% CI 0.89 to 0.97), respectively) and higher than on AP scapular radiographs (p < 0.001). The intra- and inter-observer reliability was excellent in AP scapular views and malpositions in extension/flexion (ICC ≥ 0.84) but tended to decrease with increasing viewing angle in retroversion/anteversion.

Conclusion

These data suggest that 3D reconstructions are more reproducible than AP scapular radiographs in the assessment of the GPA and should be used to compare data in different studies, to predict outcome, define malunion, and act as an indication for surgery in patients with a scapular fracture.

Suprascapular neuropathy in massive rotator cuff tears with severe fatty degeneration in the infraspinatus muscle
Authors: Kong B. Y. , Kim S. H. , Kim D. H. , Joung H. Y. , Jang Y. H. , Oh J. H.
Published: November 2016

Aims

Our aim was to describe the atypical pattern of increased fatty degeneration in the infraspinatus muscle compared with the supraspinatus in patients with a massive rotator cuff tear. We also wished to describe the nerve conduction and electromyography findings in these patients.

Patients and Methods

A cohort of patients undergoing surgery for a massive rotator cuff tear was identified and their clinical records obtained. Their MRI images were reviewed to ascertain the degree of retraction of the torn infraspinatus and supraspinatus muscles, and the degree of fatty degeneration in both muscles was recorded. Nerve conduction studies were also performed in those patients who showed more degeneration in the infraspinatus than in the supraspinatus.

Results

Out of a total of 396 patients who underwent surgery for a massive rotator cuff tear between 2006 and 2015, 35 who had more severe fatty degeneration in the infraspinatus than in the supraspinatus were identified. There were 13 men and 22 women. Their mean age was 67.2 years (56 to 81). A total of 20 (57%) had grade 4 fatty degeneration as classified by Fuchs et al, in the infraspinatus. Patte grade 3 muscle retraction was seen in 25 patients (71%). In all, eight patients (23%) had abnormal nerve conduction studies. The mean retraction of the infraspinatus was 3.6 cm (2.1 to 4.8) in patients with more severe fatty degeneration in the infraspinatus, versus 3.0 cm (1.7 to 5.5) in those with more severe degeneration in the supraspinatus (p = 0.003). The retraction ratios were 0.98 (0.61 to 1.57) and 0.77 (0.38 to 1.92), respectively (p < 0.001).

Conclusion

Fatty degeneration affecting the infraspinatus more than the supraspinatus may be, in the context of a massive rotator cuff tear, due to entrapment of the suprascapular nerve at the spinoglenoid notch. Cite this article: Bone Joint J 2016;98-B:1505–9.
Is structural hydroxyapatite tricalcium-phosphate graft or tricortical iliac crest autograft better for calcaneal lengthening osteotomy in childhood?
Authors: Martinkevich P. , Rahbek O. , Stilling M. , Pedersen L. K. , Gottliebsen M. , Søballe K. , Møller-Madsen B.
Published: November 2016

Aims

To compare the structural durability of hydroxyapatite-tricalcium phosphate (HATCP) to autologous iliac crest bone graft in calcaneal lengthening osteotomy (CLO) for pes planovalgus in childhood.

Patients and Methods

We present the interim results of ten patients (HATCP, n = 6 and autograft, n = 5) with a mean age of 11.5 years (8.2 to 14.2) from a randomised controlled non-inferiority trial with six months follow-up. The primary outcome was the stability of the osteotomy as measured by radiostereometric analysis. A non-inferiority margin of ≤ 2 mm osteotomy compression was set.

Results

At six months the data showed that the osteotomy had been compressed by a mean 1.97 mm (99.8% confidence interval -1.65 to 5.60) more in the HATCP group than in the autograft group. Migration of the CLO grafted with HATCP stabilised at six months rather than at six weeks with autograft.

Conclusion

This is the first randomised trial to compare the efficacy of HATCP graft with autograft in terms of stability of CLO in children. Because of problems with the HATCP the trial was stopped. We do not recommend HATCP graft in its current structure for use in unfixed CLOs. Cite this article: Bone Joint J 2016;98-B:1554–62.
The effect of the native kinematics of the knee on the outcome following total knee arthroplasty
Authors: Mooney L. T. , Smith A. , Sloan K. , Clark G. W.
Published: November 2016

Aims

The aim of this study was to investigate differences in pain, range of movement function and satisfaction at three months and one year after total knee arthroplasty (TKA) in patients with an oblique pattern of kinematic graph of the knee and those with a varus pattern.

Patients and Methods

A total of 91 patients who underwent TKA were included in this retrospective study. Patients (59 women and 32 men with mean age of 68.7 years; 38.6 to 88.4) were grouped according to kinematic graphs which were generated during navigated TKA and the outcomes between the groups were compared.

Results

The graphs were varus in 50 patients (55%), oblique in 19 (21%), neutral in 17 (18.5%) and valgus in five (5.5%). After adjustment for pre-operative scores and gender, compared with patients with varus knee kinematics, patients with an oblique kinematic graph had a poorer outcome with lower Knee Society scores at three months (9.2 points, p = 0.038).

Conclusion

We found four distinct kinematic graphs in knees and that patients with an oblique graph have a poorer outcome in the short-term after TKA. Cite this article: Bone Joint J 2016;98-B:1471–8.
