Hydrothermal activity, functional diversity and chemoautotrophy are major drivers of seafloor carbon cycling
Authors: Bell James B. , Woulds Clare , Oevelen Dick van 
Published: September 2017

AbstractHydrothermal vents are highly dynamic ecosystems and are unusually energy rich in the deep-sea. In situ hydrothermal-based productivity combined with sinking photosynthetic organic matter in a soft-sediment setting creates geochemically diverse environments, which remain poorly studied. Here, we use comprehensive set of new and existing field observations to develop a quantitative ecosystem model of a deep-sea chemosynthetic ecosystem from the most southerly hydrothermal vent system known. We find evidence of chemosynthetic production supplementing the metazoan food web both at vent sites and elsewhere in the Bransfield Strait. Endosymbiont-bearing fauna were very important in supporting the transfer of chemosynthetic carbon into the food web, particularly to higher trophic levels. Chemosynthetic production occurred at all sites to varying degrees but was generally only a small component of the total organic matter inputs to the food web, even in the most hydrothermally active areas, owing in part to a low and patchy density of vent-endemic fauna. Differences between relative abundance of faunal functional groups, resulting from environmental variability, were clear drivers of differences in biogeochemical cycling and resulted in substantially different carbon processing patterns between habitats.

Published: September 2017

Background The superficial femoral artery (SFA) is the most common site of lower extremity atherosclerosis, and collateral vessels from the deep femoral artery (DFA) play an important compensatory role between the iliofemoral segment and the popliteal artery. We examined SFA occlusion and collateral vessel developments in patients with diabetes mellitus using computed tomography (CT) angiography. We also compared the collateral systems from the DFA and the descending branch of the lateral circumflex femoral artery (dbLCFA) in the case of SFA occlusion.
Methods We retrospectively reviewed 1,316 sets of CT angiographic data collected from 673 patients with diabetes between 2008 and 2010. The degree of stenosis in each segment of the proximal and distal SFA and the number and size of collateral vessels originating from the DFA and dbLCFA were measured using established scoring systems. In cases where the SFA was occluded, the numbers of collateral vessels originating from the DFA and the dbLCFA vessel were compared.
Results The mean occlusion rate of the SFA was 15.6%. We noted that collateral vessels from DFA and dbLCFA were the main circulatory route in cases of occlusions of the SFA. More collateral vessels developed from the DFA than from the dbLCFA. Overall, 0.6% of the patients had only collateral systems from the dbLCFA.
Conclusion When planning to use anterolateral thigh free flaps in diabetic patients with suspected SFA total occlusion, thorough investigations of the peripheral vessels are essential.

Authors: Sperling Jeffrey , Dahlke Joshua , Sutton Desmond , Gonzalez Juan , Chauhan Suneet 
Published: September 2017

Objective The objective of this study was to compare national guidelines on the prevention of RhD alloimmunization.
Study Design We performed a review of four national guidelines on prevention of alloimmunization from the American Congress of Obstetricians and Gynecologists, Royal College of Obstetricians and Gynaecologists, Society of Obstetricians and Gynaecologists of Canada, and The Royal Australian and New Zealand College of Obstetricians and Gynaecologists. We compared the indications/contraindications, timing, dosing, formulation and route of anti-D immune globulin, and management of unique circumstances. The references were compared with regard to the number of randomized control trials, Cochrane Reviews, and systematic reviews/meta-analyses cited.
Results Variation exists in recommendations on the timing and need for consent prior to routine antenatal anti-D immune globulin administration, prophylaxis for unique circumstances (e.g., threatened abortion < 12 weeks, complete molar pregnancy), and the use of cell-free fetal DNA testing for fetal RhD genotype.
Conclusion These variations in recommendations reflect the heterogeneity of the literature on the prevention of alloimmunization and highlight the need for synthesis of evidence to create an international guideline on prevention of alloimmunization. This may improve safety, quality, optimize outcomes, and stimulate future trials.

Authors: Del Piñal F. , García-Bernal F. J. , Delgado J. , Regalado J. , Pisani D. , Sanmartín M. 
Published: September 2017

El propósito de este trabajo es presentar un método para realizar las osteotomías intraarticulares con control visual.
Método: Utilizamos los abordajes dorsales clásicos de artroscopia (3-4, 6-R) además de un portal volar radial (VR). Para visualizar la articulación radiocarpiana recurrimos sólo a la tracción sin irrigar con agua. Las osteotomías se efectuaron con osteotomos de 4 mm introducidos por los portales y bajo control visual por la óptica del artroscopio. Una vez finalizada la refractura se movilizaron y fijaron los fragmentos desplazadas mediante tornillos o placas, obteniendo en todos los casos escalones próximos a 0mm.
Conclusiones: Este procedimiento permite realizar la partición de los fragmentos por los trazos originales de fractura. La clave de esta intervención es realizar la artroscopia sin agua (técnica seca) que permite una visión nítida y la ejecución de las osteotomías sin extravasación de agua, ni pérdidas de visión.

Published: September 2017

Introducción. El sarcoma fibromixoide de bajo grado es un sarcoma de partes blandas caracterizado por un curso clínico y una histología aparentemente benigna, pero que puede dar recidivas locales y metástasis a distancia. La cirugía constituye el tratamiento de elección.Caso clínico. Varón de 30 años que presenta tumoración indolora en eminencia tenar mano izquierda de 12 meses de evolución. En la primera exploración se aprecia un nódulo duro y fijo en región tenar izquierda, que en la resonancia magnética con contraste se localizaba a la altura de la base del primer metacarpiano con captación heterogénea de contraste. La punción aspirativa con aguja fina es compatible con tumor mesenquimal, por lo que se opta por un tratamiento quirúrgico de conformidad con el paciente. El estudio anatomopatológico definitivo establece el diagnóstico de sarcoma fibromixoide de bajo grado sin infiltración tumoral de los bordes quirúrgicos y estudio de extensión negativo. Al año de control clínico, no existen indicios de recidiva tumoral, ni local ni a distancia. La presentación superficial, en extremidades superiores o en edad pediátrica es excepcional.
Relación de la inestabilidad, la laxitud ligamentosa y la traslación del metacarpiano sobre el trapecio en la aparición de artrosis trapecio metacarpiana: estudio anatómico

Published: September 2017

Los cambios degenerativos de la articulación trapecio metacarpiana (TMC) se han asociado con la laxitud ligamentosa y con la subluxación articular. El ligamento dorso-radial (LDR) y el ligamento oblicuo anterior (LOA) juegan un papel fundamental en la estabilidad articular al realizar la pinza y cuando estos ligamentos se rompen, la articulación pierde estabilidad.Objetivo: El estudio describe los ligamentos principales de la articulación TMC y valora el papel que juegan en la estabilidad articular, en la prevención de la subluxación del primer metacarpiano sobre el trapecio y la relación de estos ligamentos en la fisiopatología de la artrosis.Material y Método: Se realizó un estudio en 10 manos de cadáver fresco. Fueron 5 mujeres y 5 hombres de edad media 65 años (51-92). Se disecaron los ligamentos principales de la articulación TMC y se valoró el papel que juegan en la estabilidad. Se seccionaron aisladamente el LDR, el LOA o beak ligament, el ligamento intermetacarpiano (LIM), el ligamento oblicuo dorsal (LOD), y el ligamento colateral ulnar (LCU) observando el grado de inestabilidad que producían en la articulación TMC. La estabilidad se evaluó con el primer MTC en neutro, abducción radial, abducción palmar y oposición. El grado de desplazamiento del metacarpiano respecto del trapecio se midió en mm. El grado de artrosis de describió dividiendo las superficies en cuadrantes.Resultados: El LDR, el LOA, y el LIM juegan un papel como elementos estabilizadores de la articulación TMC. La sección del LDR dio lugar a la mayor inestabilidad con una mayor subluxación TMC. La laxitud de algunos de estos ligamentos coincide con un mayor área de destrucción articular y de cambios degenerativos. La media de desplazamiento o traslación tras la sección del LDR fue de 1.3 mm, del LOA de 1.0 mm, del LOD 0.5 mm, del LIM 0.4 mm y del LCU de 0.2 mm.La degradación del cartílago se inicia en el cuadrante radial y progresa hacia los cuadrantes palmares de la superficie articular.Conclusión: Las observaciones sugieren que la traslación del metacarpiano sobre el trapecio tiene lugar en mayor grado con la sección del LDR y esta subluxación coincide con las áreas de destrucción articular y degradación del cartílago. Nuestros resultados sostienen la hipótesis de que la inestabilidad puede ser una causa de la artrosis TMC. Este estudio sugiere que se debería de valorar la reparación del LDR.
Validität klinischer Tests zur Bestimmung des Antetorsionswinkels des Femurs
Authors: Brugner-Seewald M. 
Published: September 2017

ZusammenfassungDie Diagnosestellung des femoroazetabulären Impingements (FAI) beruht auf morphologischen Veränderungen des Hüftkopfes und/oder der
Hüftpfanne, die in bildgebenden Verfahren festgestellt werden. Eine dieser Veränderungen ist eine abnormale Antetorsion des Femurs. Diese
wird in der Literatur zudem als beitragender Faktor zur Entstehung des FAI und der Osteoarthrose, sondern auch von Low Back Pain und
Knieschmerzen diskutiert.Eine der großen Herausforderungen für Physiotherapeuten liegt darin, möglichst alle beitragenden Faktoren zu identifizieren, die die
Entstehung eines FAI oder einer Osteoarthrose begünstigen oder beschleunigen könnten und die Behandlung entsprechend anzupassen.Die vorliegende Arbeit versuchte einerseits herauszufinden, welche klinischen Tests zur Ermittlung der Antetorsion des Femurs in der
Literatur beschrieben sind und andererseits die klinische Präsentation einer veränderten Antetorsion des Femurs darzustellen.Der Craig’s Test (Trochanteric Prominence Angle Test, Ruwe’s Test) und die Hüftinnenrotation weisen auf eine klinisch relevante Validität und
Reliabilität hin. Es wird empfohlen, mehrere Tests zu kombinieren.

Mapping the relationship between religion and social policy
Authors: Pavolini Emmanuele , Béland Daniel , Jawad Rana 
Published: September 2017

AbstractReligion is a major aspect of human life that directly intersects with a number of social policy issues. Although much has been written about the religion-social policy nexus, the literature remains overly fragmented. Focusing primarily on Western Europe and North America, this review essay seeks to create a fruitful dialogue among the three main streams of research in the area, which respectively that focus on political parties, faith-based organisations, and individual behaviour. This essay has the goal of formulating a new, integrated agenda for future research on the religion and social policy nexus that also extends beyond Western societies.
MemBrain-contact 2.0: a new two-stage machine learning model for the prediction enhancement of transmembrane protein residue contacts in the full chain
Authors: Yang Jing , Shen Hong-Bin 
Published: September 2017

Abstract

Motivation
Inter-residue contacts in proteins have been widely acknowledged to be valuable for protein 3 D structure prediction. Accurate prediction of long-range transmembrane inter-helix residue contacts can significantly improve the quality of simulated membrane protein models.

Results
In this paper, we present an updated MemBrain predictor, which aims to predict transmembrane protein residue contacts. Our new model benefits from an efficient learning algorithm that can mine latent structural features, which exist in original feature space. The new MemBrain is a two-stage inter-helix contact predictor. The first stage takes sequence-based features as inputs and outputs coarse contact probabilities for each residue pair, which will be further fed into convolutional neural network together with predictions from three direct-coupling analysis approaches in the second stage. Experimental results on the training dataset show that our method achieves an average accuracy of 81.6% for the top L/5 predictions using a strict sequence-based jackknife cross-validation. Evaluated on the test dataset, MemBrain can achieve 79.4% prediction accuracy. Moreover, for the top L/5 predicted long-range loop contacts, the prediction performance can reach an accuracy of 56.4%. These results demonstrate that the new MemBrain is promising for transmembrane protein’s contact map prediction.

Multistage Decision Processes: The Impact of Attribute Order on How Consumers Mentally Represent Their Choice
Authors: Schrift Rom Y , Parker Jeffrey R , Zauberman Gal , Srna Shalena 
Published: September 2017

AbstractWith the ever-increasing number of options from which consumers can choose, many decisions are made in stages. Whether using decision tools to sort, screen, and eliminate options, or intuitively trying to reduce the complexity of a choice, consumers often reach a decision by making sequential, attribute-level choices. The current article explores how the order in which attribute-level choices are made in such multistage decisions affects how consumers mentally represent and categorize their chosen option. The authors find that attribute choices made in the initial stage play a dominant role in how the ultimately chosen option is mentally represented, while later attribute choices serve only to update and refine the representation of that option. Across 13 studies (six of which are reported in the supplemental online materials), the authors find that merely changing the order of attribute choices in multistage decision processes alters how consumers (1) describe the chosen option, (2) perceive its similarity to other available options, (3) categorize it, (4) intend to use it, and (5) replace it. Thus, while the extant decision-making literature has mainly explored how mental representations and categorization impact choice, the current article demonstrates the reverse: that the choice process itself can impact mental representations.
Asymptomatic Cardiovascular Syphilis With Aortic Regurgitation Requiring Surgical Repair in an HIV-Infected Patient
Authors: Graciaa Daniel S , Mosunjac Marina B , Workowski Kimberly A , Kempker Russell R 
Published: September 2017

Abstract
A 47-year-old man with HIV infection presented 10 years after initial secondary syphilis diagnosis and treatment for routine follow-up. His HIV was well controlled on antiretroviral therapy. Rapid plasma reagin was 1:1, and TP-PA was reactive. Physical examination revealed a wide pulse pressure, a systolic murmur, and an early diastolic decrescendo murmur. Echocardiogram revealed moderate to severe aortic regurgitation, and subsequent computed tomography angiogram showed a 6.8-cm fusiform aneurysm of the proximal ascending aorta. Aortic valve and ascending hemiarch replacement were performed. Pathology showed adventitial inflammation with plasma cells, gumma-like amorphous areas surrounded by histiocytes, and giant cells with calcified plaques. Cardiovascular syphilis, while rare, remains a relevant cause of aortic aneurysm, even in previously treated patients. The physical exam can be critical in identifying this potentially fatal complication.
Comparison of Expert Opinion, Majority Rule, and a Clinical Prediction Rule to Estimate Distal Radius Malalignment
Authors: Luokkala Toni , Flinkkilä Tapio , Paloneva Juha , Karjalainen Teemu V. 
Published: September 2017

Objectives:
To investigate the ability of individual surgeons [expert opinion (EO)] to predict distal radius fracture (DRF) healing above a threshold malalignment compared with the majority prediction of the group of surgeons [“majority rule,” (MR)] and a statistically derived clinical prediction formula [Edinburgh wrist calculator (EWC)].

Design:
Comparative diagnostic study from prospectively collected data of consecutive patients.

Setting:
Two academic level 1 and 1 academic level 2 trauma centers.

Patients/Participants:
Eighteen surgeons assessed probability of healing above a threshold malalignment (often referred to as fracture “instability”) for 71 fractures based on radiographs taken initially and after closed reduction and cast application. The probability of losing alignment according to the EWC was dichotomized (likely to lose alignment ≥0.5 vs. unlikely <0.5).

Main Outcome Measures:
Accuracy parameters of prediction of EO, MR, and EWC.

Results:
EWC and MR demonstrated higher accuracy (0.77 and 0.75, respectively) and sensitivity (0.95 and 0.79, respectively) compared with EO (accuracy, 0.66 and sensitivity, 0.58) for predicting healing above the threshold malalignment. Reliability was higher for MR (kappa 0.88) than for EWC (kappa 0.63) or EO (kappa coefficient 0.44). The negative predictive value of the EWC for healing above a threshold of malalignment was excellent (0.97).

Conclusions:
Surgeon opinion is not reliable or accurate for predicting loss of alignment of a DRF above a threshold malalignment after closed reduction and immobilization. Dichotomized EWC may be a useful tool in predicting loss of alignment (instability) of a DRF.

Level of Evidence:
Diagnostic Level II. See Instructions for Authors for a complete description of levels of evidence.
Elevated Postvoid Residual Urine Volume: Identifying Risk Factors and Predicting Resolution in Women With Pelvic Organ Prolapse
Authors: Ulrich Amanda , Davis Patricia , Propst Katie , O'Sullivan David M. , Tulikangas Paul 
Published: September 2017

Objectives
This study aims to identify risk factors for elevated preoperative postvoid residual (PVR) and persistently elevated postoperative PVR and to evaluate the resolution rate of elevated PVR urine volume in patients undergoing reconstructive surgery for pelvic organ prolapse (POP).

Methods
This was a retrospective cohort study comparing 50 women with elevated preoperative PVR (≥100 mL) and 50 women with normal PVR (<100 mL). Preoperative demographic, physical examination, urodynamic data, type of surgery performed, and postoperative trial of void data were collected. Variables were evaluated for association with elevated PVR using Student t test or Mann-Whitney U test, and χ2 or Fisher exact test.

Results
The elevated PVR cohort was older (65.5 ± 13.3 vs 60.6 ± 10.1 years, P = 0.04). The cohorts did not differ by body mass index, parity, number of cesarean deliveries, prior hysterectomy, incontinence, prolapse surgery, menopausal status, hormone replacement therapy, history of recurrent urinary tract infections, diabetes mellitus, or maximum bladder capacity. Most patients had preoperative anterior prolapse stage 2 or 3. Complaints of incontinence, incomplete bladder emptying, and overactive bladder did not differ between groups. Performed Surgical procedures, cystoscopy findings, and rate of postoperative trial of void failures did not differ between groups. One patient per cohort learned clean intermittent self-catheterization for persistently elevated PVR.

Conclusions
All women undergoing surgery for POP had postoperative resolution of elevated PVR. Patients with nonneurogenic-elevated PVR can be reassured that bladder emptying will improve after surgical repair of POP.
Increasing Anteroposterior Genital Hiatus Widening Does Not Limit Apical Descent for Prolapse Staging During Valsalva's Maneuver: Effect on Symptom Severity and Surgical Decision Making
Authors: Guanzon Anna , Heit Michael , Khoder Waseem 
Published: September 2017

Objective
Determine if anteroposterior genital hiatus (GH) widening obscures rather than facilitates signs and symptoms, inadvertently altering management decisions for women with pelvic organ prolapse (POP) during Valsalva's Maneuver, at a given total vaginal length (TVL).

Methods
We performed a retrospective cohort with nested cross-sectional study of patients who underwent POP surgery. Data from obstetric and gynecologic history, preoperative and postoperative physical examinations, and 20-item Pelvic Floor Distress Inventory (PFDI-20) and 7-item Pelvic Floor Impact Questionnaire (PFIQ-7) scores were extracted. Study participants were compared in 2 groups: anteroposterior widened (>3 cm) and not widened (≤3 cm) GH, for baseline leading edge and POP stage, while controlling for TVL. Baseline PFDI-20 and PFIQ-7 scores were evaluated within GH groups. Delta GH, PFDI-20, and PFIQ-7 scores after apical suspension with and without posterior colporrhaphy were compared to assess the clinical value of the procedure.

Results
Study participants with anteroposterior GH widening during Valsalva maneuver had greater baseline leading edge descent and higher POP stage compared with those without anteroposterior GH widening after controlling for TVL. Baseline PFDI-20 and PFIQ-7 scores were similar within both GH categories controlling for prolapse severity. Adding posterior colporrhaphy to apical suspension resulted in a greater anteroposterior GH reduction without improving delta PFDI-20 or PFIQ-7 scores.

Conclusions
Facilitation through herniation rather than obscuration from anteroposterior GH widening explains why patients will not be undertreated based on signs and symptoms of disease. Adding posterior colporrhaphy to apical suspension more effectively reduces anteroposterior GH widening without differential improvement in symptoms rendering the operation to no more than a cosmetic procedure.
