Objectives This study aimed to clarify the positional relationship between the left brachiocephalic vein and its surrounding vessels and to analyse the association between this positional relationship and ageing. Method Chest contrast-enhanced computed tomography was performed for 100 adults. The contact number between left brachiocephalic vein and surrounding vessels (aorta, brachiocephalic artery, left common carotid artery and left subclavian artery) was determined. The correlations of ageing with the cross-sectional areas of left brachiocephalic vein crossing brachiocephalic artery and left common carotid artery and peripheral end of left brachiocephalic vein were analysed. Results LBV was in contact with aorta in 19, brachiocephalic artery in 97, left common carotid artery in 90 and left subclavian artery in 21 patients. There were significant negative correlations of ageing with the cross-sectional areas of left brachiocephalic vein crossing brachiocephalic artery and left common carotid artery and peripheral end of left brachiocephalic vein. Conclusions Brachiocephalic artery and left common carotid artery have easy contact with left brachiocephalic vein. There was a negative relationship between the cross-sectional area of left brachiocephalic vein and age.

AimTo analyse the repeatability of vessel density (VD) measurements using optical coherence tomography angiography (OCTA) in patients with retinal diseases.MethodsTwo consecutive VD measurements using OCTA were analysed prospectively in patients with retinal diseases (diabetic macular oedema (DME), retinal vein occlusion (RVO) with macular oedema, epiretinal membrane (ERM), wet age-related macular degeneration (AMD)). The intraclass correlation coefficient (ICC), coefficient of variation (CV) and test-retest SD of VD measurements were assessed, and linear regression analyses were conducted to identify factors related to repeatability.ResultsA total of 134 eyes were analysed involving 20 eyes with DME, 44 eyes with RVO with macular oedema, 50 eyes with ERM and 20 eyes with wet AMD. The mean age was 64.9 years, and the mean best-corrected visual acuity (BCVA) was 0.24. The mean central macular thickness (CMT) was 391.6 µm, and the mean ganglion cell-inner plexiform layer (GC-IPL) thickness was 61.4 µm. In all four diseases, the ICC and CV of the full VD were 0.812 and 6.72%, respectively. Univariate analyses showed that the BCVA (B, 8.553; p=0.031), signal strength (B, −1.688; p=0.050), CMT (B, 0.019; p=0.015) and mean GC-IPL thickness (B, −0.103; p=0.001) were significant factors that affected the repeatability. Multivariate analyses of these factors showed a significant result for the GC-IPL thickness.ConclusionsMeasurements of the VD using OCTA showed relatively good repeatability for various retinal diseases. The BCVA, signal strength, CMT and GC-IPL thickness affected the repeatability, so these factors should be considered when analysing the VD.

Objective To define the anatomical variations of small saphenous vein (SSV) for varicose vein (VV) surgery by three-dimensional computed tomography venography (3D-CTV) and to analyse the impact of this preoperative evaluation on surgical outcomes. Methods A total of 120 consecutive limbs with SSV insufficiency having undergone VV surgery from January 2005 until December 2007 were enrolled. The medical records and images were analysed retrospectively. Results The relationship between SSV and gastrocnemial vein (GNV) were categorized into two: (a) SSV and GNV drained to popliteal vein (PV) separately (100 limbs, 87%) and (b) SSV and GNV made common channel which drained to PV (15 limbs, 13%). Saphenopopliteal junction morphology was normal (75 limbs), severe tortuosity near PV (19 limbs), ampullary ectasia (4 limbs) and duplicated drainage to PV (2 limbs). No recurrence of VV was noted. Conclusions CTV can provide thorough preoperative anatomic information of the SSV variations and reduce the recurrence of VV.

Background: Graft infection after vascular prosthetic reconstruction for the treatment of peripheral arterial occlusive disease (PAOD) is a rare but severe complication with poor outcome. The options for surgical treatment are not uniformly accepted and remain controversial. Patients and methods: We retrospectively analyzed the histories of 30 patients treated for prosthetic graft infection (Szilagyi grade III) in our hospital between 1994 and 1999 to determine which forms of treatment were best suited for which types of patient. In the majority of cases the initial treatment was lower-extremity bypass surgery. The most frequent location of infection was the groin (73%). Staphylococci (13% of which were methicillin resistant) were the most common type of bacteria. The overall incidence of prosthetic infection was 2.3%. Results: After confirmation of the infection by computed tomography (CT) or white blood cell scintigraphy, one of the following 5 forms of surgical treatment was performed: 1. Removal of the infected prosthesis and its simultaneous replacement by an autologous vein bypass. 2. Bypass removal and secondary replacement by an autologous vein. 3. Extra-anatomical replacement. 4. Graft removal and primary amputation. 5. Local therapy with debridement and secondary wound healing. In some patients primary amputation after graft infection was necessary to prevent further deterioration with fulminant sepsis. The overall mortality was 17%, the amputation rate was 60%. Conclusions: The best results were achieved by early complete removal of the alloplastic material and one-step replacement by either an autologous vein or extra-anatomic bypass. This resulted in a limb salvage rate of 54% and 40% and mortality rates of 9% and 0%, respectively.

The wings of a dragonfly have many complicated structures. The configuration of the costal vein of the wings of a dragonfly is different from them of other insects. So, we paid attention to the configuration of the costal vein of the wings in this study. In order to know the functions and structures of the wings of a dragonfly, several 3-D models of the wing of Anotogaster Sieboldii were created, and calculated with the 3-D finite element method. In addition, we created a 3-D model of the wing of Hybris Subjacens which has the configuration of original wing, and compared the models of Anotogaster Sieboldii and Hybris Subjacens. As a result, it was clarified that the arch configuration of the costal vein controls the bending and the torsion of the wings.

De precedentes etudes avaient montre que le venin du diplopode glomeris marginata contient deux alcaloides originaux: la glomerine et l'homoglomerine. Nous avons identifie ces alcaloides dans le venin de deux autres especes: g. Annulata et g. Guttata, ainsi qu'un nouveau derive de la quinazolinone, la 6-methoxy-glomerine, dont la structure a ete etablie sur la base de diverses donnees spectrales (uv, rmn-1h, ms). Ces alcaloides sont faiblement toxiques a l'egard des insectes et seules la glomerine et l'homoglomerine ont montre une toxicite significative a l'egard des vertebres (dl50 9. 7 et 6. 4 mg/kg en injection intraperitoneale chez la souris). Les 2,5-dialkylpyrrolidines presentes dans le venin des fourmis du genre monomorium sont des insecticides naturels provoquant une paralysie flasque. Nous avons determine le mecanisme d'action de la 2-(1non-8enyl)-5-(1non-8enyl)pyrrolidine (pyr 9) sur le systeme nerveux d'invertebre, en utilisant deux types de preparations in vitro de la chaine nerveuse ventrale de l'ecrevisse procambarus clarkii). Nos resultats montrent clairement que la pyr 9 bloque la conduction nerveuse sans affecter le potentiel de repos. Des experiences de potentiel impose sur axone ont demontre que ce blocage est du a une inhibition du courant sodium, qui s'accompagne d'un deplacement de la courbe d'inactivation du courant sodium vers les potentiels plus negatifs

L'étude de la stratégie d'envenimation utilisée par les trois cônes piscivores c. Catus, c. Ermineus et c. Consor a permis de montrer que ces trois cônes utilisent la stratégie des harpooners qui harponnent leur proie, a l'aide d'une dent radulaire sophistiquée, avant de l'ingérer. Les études élèctrophysiologiques, réalisées sur des préparations nerf-muscle d'amphibien, montrent que les venins de c. Catus, c. Ermineus et c. Consor contiennent (I) des toxines qui agissent au niveau présynoptique en augmentant l'excitabilité des terminaisons nerveuses et (II) des toxines qui agissent au niveau postsynaptique en bloquant les récepteurs nicotiniques de l'acétylcholine. Nous avons entrepris la caractérisation les toxines contenues dans les venins de c. Consor et c. Ermineus qui agissent au niveau présynoptique. Nous avons ainsi isole deux nouvelles conotoxines : la conotoxine-evia a partir du venin de c. Ermineus et la CCTX a partir du venin de c. Consor. L'étude des effets biologiques induits par ces deux toxines a montre qu'elles étaient, du moins en partie, responsables du choc excitotoxique observe lors de l'envenimation d'un poisson par ces cônes. Seule la conotoxine-evia est active chez le mammifère avec une ed50 de 4,1 pmoles/g de souris. Cette toxine est un polypeptide de 32 résidus d'acides amines réticules par trois ponts disulfures. Le mécanisme d'action physiologique de cette toxine a été étudié sur des préparations neuromusculaires et des axones myelinises isolés d'amphibien. L'ensemble des résultats obtenus montre que l'action de la conotoxine evia est d'inhiber l'inactivation des canaux sodium neuronaux sans affecter ceux des muscles squelettiques. Cette action se traduit par une augmentation (I) de la durée du potentiel d'action au niveau des axones et (II) de l'excitabilité membranaire au niveau des terminaisons nerveuses. La CCTX est un polypeptide de 30 résidus d'acides amines et possède une modification post-traductionnelle au niveau du résidu 7. Des études élèctrophysiologiques ont montre que cette toxine active sélectivement les canaux sodium neuronaux au potentiel de repos, ce qui provoque une augmentation de l'excitabilité nerveuse et ce, sans affecter le muscle squelettique. La spécificité d'action de la CCTX et de la conotoxine-evia en font des outils pharmacologiques remarquables pour distinguer les canaux sodiques neuronaux des canaux sodiques musculaires au sein d'une même espèce.

Le venin du cône piscivore conus consors a ete etudie afin d'isoler et de caractériser de nouvelles conotoxines utiles pour l'étude de ces protéines membranaires. Deux alphaconotoxines, l'alpha-cnia et l'alpha-cnib, qui ciblent les récepteurs nicotiniques de l'acetylcholine ont été isolées du venin. La synthèse de l'alpha-cnia a ete realisee par synthese peptidique en phase solide selon la strategie fmoc. Les études de liaison de l'alpha-cnia, a des récepteurs nicotiniques de torpille et alpha 7, ont montre que cette toxine se fixe spécifiquement sur les récepteurs de type musculaire. Enfin, l'élucidation de la structure tridimensionnelle par rmn de l'alpha-cnia a permis de mettre en évidence la présence de différents conformeres en solution ainsi qu'une heterogeneite conformationnelle du conformere majoritaire. Une nouvelle omega-conotoxine, l'omega-cnviia, a été isolée du venin, caractérisée puis obtenue par synthèse peptidique en phase solide selon la méthode fmoc. L'étude de la liaison aux synaptosomes de rat, realisee par radiomarquage a l'iode 125 de l'omega-cnviia, montre que le peptide se lie de façon spécifique et réversible au canaux calcium de type n, avec un k d de 36 pm. Cependant, cette toxine présente un profil pharmacologique différent de l'omega-gvia. L'omega-cnviia représente donc un nouvel outil pharmacologique pour l'étude de canaux calcium de type n. Finalement, trois excitotoxines, les delta-cnvia, cnvib et cnvic, ont été isolées. Elles sont en partie responsables du choc excitotoxique observe lors de l'envenimation de la proie. L'effet biologique de la delta-cnvia a été étudié au niveau de la jonction neuromusculaire et sur des cellules du système nerveux central de vertèbres. L'ensemble des résultats obtenus montre que la delta-cnvia inhibe l'inactivation des canaux sodium sensibles au potentiel de membrane.

Les venins animaux, par leur richesse biochimique et la diversité de leurs cibles moléculaires, sont une source importante de molécules dont les applications potentielles sont nombreuses. La recherche de nouveaux médicaments pour remplacer certains antibiotiques devenus inefficaces face à l'apparition de résistances, est un axe fort de la recherche pharmacologique. Depuis plus de 40 ans, la découverte de toxines animales montre que les animaux venimeux peuvent être les « pharmaciens du futur ». Le venin de fourmis est encore peu étudié. Seul celui de quelques espèces a été exploré, avec à chaque fois la mise en évidence de toxines originales. L'objectif de cette thèse a été l'étude du venin de fourmis exotiques sur la base d'une approche pluridisciplinaire qui combine l'analyse biochimique et la toxinologie. Les travaux se sont articulés autour de deux axes principaux : (1) Recherche d'activités biologiques sur insectes et bactéries ; (2) Fractionnement des venins par des techniques séparatives et analyse biochimique des peptides isolés par spectrométrie de masse. Deux espèces de fourmis ont été choisies en fonction de leur mode de vie : Crematogaster striatula, une espèce arboricole et Tetramorium bicarinatum, une espèce terricole. Les différentes activités biologiques de leurs sécrétions venimeuses ont été conduites par test MTT. Le liquide de Dufour de C. striatula en plus de sa capacité à éloigner les espèces concurrentes montre une capacité à paralyser les termites de manière irréversible. Concernant le venin de T. bicarinatum, deux peptides ont été isolés et identifiés par spectrométrie de masse. La bicarinaline, peptide de 20 acides aminés et amidé à son extrémité C-terminale, s'est démarqué par son action antibactérienne à large spectre. Testée sur deux souches de staphylocoques, ce peptide se révèle aussi efficace voire plus puissant que la méllitine, peptide antimicrobien du venin d'abeille. La bicarinaline apparaît comme un candidat potentiel pour la conception de nouveaux traitements antibiotiques
Animal venoms, by their biochemical richness and diversity of molecular targets, are a highly significant source of new molecules, with numerous potential applications. A major thrust of present pharmacological research now concerns drugs to replace certain antibiotics, proven ineffective due to the appearance of resistant strains. And discoveries of animal toxins over the past 40 years or more, have shown that venomous species could be the « pharmacists of the future », with only a few species of ants' venoms having been studied, but each time resulting in the description of original toxins. The aim of this thesis has been to study the venom of tropical ants using a multidisciplinary approach combining biochemical analysis and toxinology, centred on two main areas: (1) Research into their biological activity on insects and bacteria; (2) Fractionation of venoms using separative techniques, plus biochemical analysis of the peptides isolated using mass spectrometry. Two species of ant have been chosen based on their lifestyles: Crematogaster striatula is arboricolous and Tetramorium bicarinatum, terricolous, and the different biological activities of their crude venoms have been investigated using the MTT test. The Dufour liquid of C. striatula, in addition to its ability to scare away competitors, can definitively paralyse termites. For the venom of T. bicarinatum, two peptides have been isolated, and identified using mass spectrometry. Bicarinalin, a short 20 amino acid residues C-terminally amidated peptide, was notable for its wide spectrum antibacterial activity which, when tested on two Staphylococcus strains, proved to be at least if not more potent than mellitin, the antimicrobial peptide from bee venom. Bicarinalin would thus appear to be a good candidate for the development of new antibiotic drugs

Le venin de cônes (Conidae) constitue une source abondante de peptides bioactifs (conopeptides ou conotoxines). Dans cette thèse, nous avons comparé le venin de deux cônes malacophages: Conus bandanus et Conus marmoreus. En utilisant nano-LC ESI MS et MS/MS, nous mettons en évidence la présence de 92 peptides communs, ce qui représente 24,4% (de 376 peptides) et 18,4% (de 499 peptides) composant les venins de C. Bandanus et C. Marmoreus, respectivement. L'estimation des ponts disulfures révèle que 75% et 61% des conopeptides dans les venins de C. Bandanus et C. Marmoreus sont riches en ponts disulfures. Les mêmes séquences en acides aminés se retrouvent pour un certain nombre de conopeptides des deux espèces, qui montrent aussi des différences dans lexpression dautres conopeptides. Nous avons également à partir du venin de C. Bandanus isolé, purifié et caractérisé les -BnIA/B/C/D (superfamille A), les BnIIIA/B/C/D/E (superfamille M), BnVA (superfamille T) et BnVIA (superfamille H)
Cone snail venoms (family Conidae) are a rich source of small bioactive peptides (conotoxins or conopeptides). In this thesis, we compared the venom of the two molluscivorous snails Conus bandanus and Conus marmoreus. Using nano-LC ESI MS and MS/MS we demonstrate the presence of 92 common peptides, representing 24,4% (out of 376 peptides) and 18,4% (out of 499 peptides) component in venoms of C. Bandanus and C. Marmoreus, respectively. The overall estimation of conopeptide disulphide bridges reveals 75% and 61% of disulphide-rich peptides in C. Bandanus and C. Marmoreus venom components, respectively. The same amino acid sequences were found for a number of peptides in the two species, which also show differences in the expression of other conopeptides. We also have isolated, purified and characterized novel conotoxins from C. Bandanus venom such as the -BnIA/B/C/D (A-superfamily), the BnIIIA/B/C/D/E (M-superfamily), BnVA (T-superfamily) and BnVIA (H-superfamily)

L’objectif est de distinguer les îlots boisés relictuels des néoformés dans une matrice agricole, de les recenser avant de les caractériser et d’évaluer leur biodiversité et pour finir d’en tirer un modèle. La méthode associe le recours aux archives et aux photographies aériennes à l’enquête de terrain (1996-2007). L’approche cartographique s’est faite par analyse régressive (2004-1620). Le seuil temporel permet de reconnaître 152 îlots (<50ha) dont l’existence est attestée avant 1620. L’analyse régressive s’appuie sur le réseau viaire, élément fixe et structurant du paysage, pour cartographier les petits bois.On constate une forte relation entre la localisation des îlots relictuels, les tracés antiques et les chemins médiévaux. La caractérisation et l’évaluation de la biodiversité des relictuels s’effectuent selon une démarche spatio-temporelle pluriscalaire, et à partir d’une comparaison avec les îlots néoformés. L’analyse à partir de la canopée informe sur la texture de la couverture boisée et la dynamique du manteau forestier, sur les coupes, les lisières et le réseau viaire intraforestier. L’analyse de la structure interne porte sur la diversité taxinomique et la diversité écologique des espèces végétales et des espèces aviaires indicatrices. Ces analyses font apparaître la spécificité des relictuels, dont est proposé un modèle. Il s’agit soit de fragments de forêts anciennes, soit en plus grand nombre de formations boisées secondaires mais anciennes, gallo-romaines, mérovingiennes ou médiévales
The purpose is to distinguish the relictual forest islands from the recent ones in an agricultural matrix; to inventory and characterize them and to assess their biodiversity, and eventually to develop a model. The method combines the resort to archives and aerial photographs with field studies (1996-2007). The mapping approach has been based on regression analysis (2004-1620). The time threshold has made it possible to identify 152 woodlots (<50ha) which presence was attested before 1620. The regression analysis to map the wood patches has been based on the path network, which is a fixed and structuring element of the landscape. There is a strong relation between the location of the relictual forest islands, the antique tracks and the medieval paths. The characterization and assessment of the relictual forest islands biodiversity have been carried out following a time and space pluri-scalar approach and from a comparison with recent forest islands. The analysis was based on the shapeless canopy, the texture and dynamics of the forest cover, the cuttings, the edges and the internal forest path network. The analysis of the internal structure focuses on the taxonomic diversity and the ecological diversity of the plant species and the indicator bird species. These analyses have stressed the specificity of the relictual forest islands, a model of which has been developed. They are either fragment of ancient forests, or, in most cases, secondary but old forest forms from the Gallo-Roman, Merovingian or medieval time

Prior to 2000, most investigators had conducted their research in the same vein as that performed in greater volume on adults, and appealed for progress in this regard. While significant progress has been made in the intervening years, there remains, regrettably, a lack of consensus in terms of how data should be gathered (which tools and protocols are appropriate) and analysed statistically, making interpretations of validity and reliability quite difficult. In the past 10 years existing scales have been refined and ‘new’ ones have been constructed and promoted across a range of exercise modalities. Chapter 11 describes these advances and controversies and present the current status of the application of effort perception research in the paediatric exercise domain.

This chapter presents an alternative to the popular critical vein that sees Joyce’s Ulysses and early cinema as conveying a mechanical, impersonal view of the world. It is argued that Ulysses and certain genres of early cinema were engaged—naively or otherwise—in a revaluation of Cartesian dualism, involving the reappraisal of mind/body and human/machine binaries. The physical comedy of Bloom and Charlie Chaplin is analysed with reference to phenomenological ideas on prosthesis and the machine–human interface, while other genres of early cinema, such as Irish melodrama and trick films, are considered in the light of phenomenological theories of gesture and embodiment. By comically mocking mind/body separation and depicting the inseparability of subjectivity and corporeality, Joyce and the early film-makers go beyond the ideas of Bergson and anticipate Merleau-Ponty’s later notion of the ‘body-subject’.

This book reviews the practice of vascular anesthesia, which is now increasingly recognized as a subspecialty of anesthesia, and looks at developments and latest evidence in neuraxial, regional, and general anesthesia techniques. It explores essential topics on vascular anatomy, common vascular procedures, and anesthetic techniques in general and regional anesthesia. It also includes subjects relating to complications, perioperative patient monitoring, and post-operative management. The book begins with an analysis of the basic vascular anatomy and physiology, which covers the three components of the vascular system where oxygen, nutrients, and metabolites exchange: artery, vein, and capillaries. It ends with the anesthetic approach on patients that are presented for vascular surgery and considered to be a very sick, comorbid population with higher ASA classification.

This article appears in theOxford Handbook of New Audiovisual Aestheticsedited by John Richardson, Claudia Gorbman, and Carol Vernallis. This chapter examines the changing relationships of sounds, places, and their cultural meanings in Turkish films located in Istanbul. Starting with a brief review of the historical context of Turkish film sound and sonic representations of Istanbul, the chapter then analyzes two recent films set in middle-class apartment homes,11’e 10 kalaandUzak, which represent the auteur vein of new Turkish cinema. Both feature subtle and delicate sound design and evidence a form of heightened realism that contrasts with traditional approaches, shifting the focus of Istanbul’s soundscapes from public to private. Although the locations and characters of both these films are remarkably similar, their soundtracks differ in rendering the experience of urbanity and strategies of acoustic privacy by the transcoding of soundmarks and the use of transphonia in scenes.

Transoesophageal echocardiography (TOE), a minimal-risk, semi-invasive imaging procedure is nowadays an indispensable part of routine echocardiography. It is mainly necessary and indicated: ◆ To analyse some structures insufficiently seen transthoracically, such as the left atrial appendage or the thoracic aorta. ◆ In situations that prohibit the use of conventional transthoracic windows, such as the patient undergoing cardiac surgery.As in transthoracic echocardiography (TTE), the TOE examination consists of a sequence of views defined by internal landmarks; unlike TTE, depending on the patient’s tolerance and the clinical question, not all of these have to be obtained in every examination. Important typical indications for TOE are the search for signs of endocarditis, the search for cardiogenic emboli, diagnosis of left atrial (appendage) thrombi before cardioversion, diagnosis of aortic dissection, characterization of mitral and aortic valve pathology especially in the context of surgical repair, intraoperative monitoring of left ventricular function, and monitoring of interventional cardiac procedures monitored.For some indications, intracardiac echocardiography has been found useful. This procedure involves insertion of a transducer-tipped catheter into the caval vein and advancement to the right heart, or intra-aortic placement. Applications are electrophysiological procedures, interventional closure of atrial septal defect, aortic stent placement, and others.

Animal models are designed to be preliminary tools for a better understanding of the pathogenesis, improvement in diagnosis, prevention, and therapy of vascular diseases in humans. Animal models are easily manageable, as compounding effects of dietary and environmental factors can be controlled experimentally. Blood vessel samples can be taken for detailed experimental and biomolecular examination. A thorough understanding of the animal models used is necessary and complete analysis must be validated so that the data can be extrapolated to humans. There are several species that are used for studying vascular pathophysiology, including mice, rats, rabbits, and pigs. Attracted by the well-defined genetic systems, a number of investigators have begun to use the mouse as an experimental system for arteriosclerosis research. Because vascular disorder is a complicated disease, which includes spontaneous (native) atherosclerosis, transplant arteriosclerosis, vein graft atherosclerosis, and angioplasty-induced restenosis, several models for studying all types of vascular disease have recently been established. Using these animal models, much knowledge concerning the pathogenesis of the disease and therapeutic intervention has been gained. This chapter will not attempt to cover all aspects of animal models, but will rather focus on the major progress in understanding the pathophysiology of the vasculature, the (dis)advantages of a variety of models, and how specific models can be appropriately chosen for different purposes of study.

‘PHILOSOPHY, or the doctrine and discipline of ideas’ as S. T. Coleridge understood it, is the theme of this book. It considers the most vital and mature vein of Coleridge’s prose writings to be ‘the contemplation of ideas objectively, as existing powers’. A theory of ideas emerges in critical engagement with thinkers including Plato, Plotinus, Böhme, Kant, and Schelling. A commitment to the transcendence of reason, central to what Coleridge calls ‘the spiritual platonic old England’, distinguishes him from his German contemporaries. This book pursues a theory of contemplation that draws from Coleridge’s theories of imagination and the ‘Ideas of Reason’ in his published texts and extensively from his thoughts as they developed throughout published works, fragments, letters, and notebooks. He posited a hierarchy of cognition from basic sense intuition to the apprehension of scientific, ethical, and theological ideas. The structure of the book follows this thesis, beginning with sense data, moving upwards into aesthetic experience, imagination, and reason, with final chapters on formal logic and poetry that constellate the contemplation of ideas. Coleridge’s Contemplative Philosophy is not just a work of history of philosophy; it addresses a figure whose thinking is of continuing interest, arguing that contemplation of ideas and values has consequences for everyday morality and aesthetics, as well as metaphysics. The book also illuminates Coleridge’s prose by analysis of his poetry, notably the ‘Limbo’ sequence. The volume will be of interest to philosophers, intellectual historians, scholars of religion, and of literature.

Objectives. This systematic review evaluates breast reconstruction options for women after mastectomy for breast cancer (or breast cancer prophylaxis). We addressed six Key Questions (KQs): (1) implant-based reconstruction (IBR) versus autologous reconstruction (AR), (2) timing of IBR and AR in relation to chemotherapy and radiation therapy, (3) comparisons of implant materials, (4) comparisons of anatomic planes for IBR, (5) use versus nonuse of human acellular dermal matrices (ADMs) during IBR, and (6) comparisons of AR flap types. Data sources and review methods. We searched Medline®, Embase®, Cochrane CENTRAL, CINAHL®, and ClinicalTrials.gov from inception to March 23, 2021, to identify comparative and single group studies. We extracted study data into the Systematic Review Data Repository Plus (SRDR+). We assessed the risk of bias and evaluated the strength of evidence (SoE) using standard methods. The protocol was registered in PROSPERO (registration number CRD42020193183). Results. We found 8 randomized controlled trials, 83 nonrandomized comparative studies, and 69 single group studies. Risk of bias was moderate to high for most studies. KQ1: Compared with IBR, AR is probably associated with clinically better patient satisfaction with breasts and sexual well-being but comparable general quality of life and psychosocial well-being (moderate SoE, all outcomes). AR probably poses a greater risk of deep vein thrombosis or pulmonary embolism (moderate SoE), but IBR probably poses a greater risk of reconstructive failure in the long term (1.5 to 4 years) (moderate SoE) and may pose a greater risk of breast seroma (low SoE). KQ 2: Conducting IBR either before or after radiation therapy may result in comparable physical well-being, psychosocial well-being, sexual well-being, and patient satisfaction with breasts (all low SoE), and probably results in comparable risks of implant failure/loss or need for explant surgery (moderate SoE). We found no evidence addressing timing of IBR or AR in relation to chemotherapy or timing of AR in relation to radiation therapy. KQ 3: Silicone and saline implants may result in clinically comparable patient satisfaction with breasts (low SoE). There is insufficient evidence regarding double lumen implants. KQ 4: Whether the implant is placed in the prepectoral or total submuscular plane may not be associated with risk of infections that are not explicitly implant related (low SoE). There is insufficient evidence addressing the comparisons between prepectoral and partial submuscular and between partial and total submuscular planes. KQ 5: The evidence is inconsistent regarding whether human ADM use during IBR impacts physical well-being, psychosocial well-being, or satisfaction with breasts. However, ADM use probably increases the risk of implant failure/loss or need for explant surgery (moderate SoE) and may increase the risk of infections not explicitly implant related (low SoE). Whether or not ADM is used probably is associated with comparable risks of seroma and unplanned repeat surgeries for revision (moderate SoE for both), and possibly necrosis (low SoE). KQ 6: AR with either transverse rectus abdominis (TRAM) or deep inferior epigastric perforator (DIEP) flaps may result in comparable patient satisfaction with breasts (low SoE), but TRAM flaps probably increase the risk of harms to the area of flap harvest (moderate SoE). AR with either DIEP or latissimus dorsi flaps may result in comparable patient satisfaction with breasts (low SoE), but there is insufficient evidence regarding thromboembolic events and no evidence regarding other surgical complications. Conclusion. Evidence regarding surgical breast reconstruction options is largely insufficient or of only low or moderate SoE. New high-quality research is needed, especially for timing of IBR and AR in relation to chemotherapy and radiation therapy, for comparisons of implant materials, and for comparisons of anatomic planes of implant placement.
