Minute hands of clocks indicating the same time are not perceived as haptically parallel
Authors: Kappers Astrid M. L. 
Published: February 2018

AbstractMany studies have already shown that a large idiosyncratic orientation difference is needed to perceive two bars that are far apart as haptically parallel. There exist also strong indications that if such bars are imagined to be minute hands of clocks, errors made in clock time estimates and clock time settings are much smaller. The current study investigated this seemingly discrepancy. Participants partook in three experiments: parallel setting, clock time estimate and clock time setting, in this order. As the individual parallel settings were used in the subsequent clock time estimate experiment, and the estimated clock times in the clock time setting experiment, the deviations could be compared directly. In all three experiments, the deviations were systematic and idiosyncratic, and consistent with a biasing influence of an egocentric reference frame. However, the deviations in the two clock time experiments were indeed much smaller than in the parallel setting experiment. Task instruction and strengthened focus on an allocentric reference frame are the most likely explanations. These findings provide fundamental insights in the processing of spatial information. Taking these findings into account when designing haptic devices may make these more intuitive.
Manual Versus Automated Narrative Analysis of Agrammatic Production Patterns: The Northwestern Narrative Language Analysis and Computerized Language Analysis
Authors: Hsu Chien-Ju , Thompson Cynthia K. 
Published: February 2018

Purpose
The purpose of this study is to compare the outcomes of the manually coded Northwestern Narrative Language Analysis (NNLA) system, which was developed for characterizing agrammatic production patterns, and the automated Computerized Language Analysis (CLAN) system, which has recently been adopted to analyze speech samples of individuals with aphasia (a) for reliability purposes to ascertain whether they yield similar results and (b) to evaluate CLAN for its ability to automatically identify language variables important for detailing agrammatic production patterns.

Method
The same set of Cinderella narrative samples from 8 participants with a clinical diagnosis of agrammatic aphasia and 10 cognitively healthy control participants were transcribed and coded using NNLA and CLAN. Both coding systems were utilized to quantify and characterize speech production patterns across several microsyntactic levels: utterance, sentence, lexical, morphological, and verb argument structure levels. Agreement between the 2 coding systems was computed for variables coded by both.

Results
Comparison of the 2 systems revealed high agreement for most, but not all, lexical-level and morphological-level variables. However, NNLA elucidated utterance-level, sentence-level, and verb argument structure–level impairments, important for assessment and treatment of agrammatism, which are not automatically coded by CLAN.

Conclusions
CLAN automatically and reliably codes most lexical and morphological variables but does not automatically quantify variables important for detailing production deficits in agrammatic aphasia, although conventions for manually coding some of these variables in Codes for the Human Analysis of Transcripts are possible. Suggestions for combining automated programs and manual coding to capture these variables or revising CLAN to automate coding of these variables are discussed.
I Have to/Get to Teach Counseling: Now What? A Personal Essay
Authors: Hale Sue 
Published: February 2018

AbstractFaculty receiving the assignment to teach a course in counseling to Au.D. students often have limited background in teaching the requisite skills and knowledge associated with counseling. A period of self-reflection regarding transferable skills for counseling as well as guidance from colleagues may assist in developing core concepts for the content of the class. Theoretical underpinnings, understanding and respecting patient values, and listening and valuing are significant perspectives for students to develop as they approach the broad content of a counseling course.

Published: February 2018

AbstractThe all-inside technique (AIT) for anterior cruciate ligament reconstruction (ACLR) is gaining popularity as a more anatomic, less invasive, technique with the potential for more rapid recovery. This systematic review aims to critically assess components of the technique, its safety profile, outcomes, and complications. PUBMED, EMBASE, and MEDLINE were searched for studies discussing primary ACLR using the AIT. Article screening, quality assessment, and data abstraction were completed in duplicate, and a minimal clinically important difference (MCID) was used to frame the descriptive results in a clinically significant context. A total of 13 studies satisfied the inclusion criteria. Five-hundred twenty six patients (mean age 31.9 ± 5.9 years) underwent ACLR using the AIT. The mean follow-up was 18.2 ± 7.7 months. Graft choice included autograft (73.8%) and allograft (26.2%). Drilling techniques for femoral sockets were outside-in (53.4%) and through the anteromedial portal (35.4%), whereas tibial sockets were drilled outside-in (35.0%) and through the superomedial portal (3.8%). The rehabilitation protocol had an immediate focus on obtaining full knee extension, jogging permitted 2 to 4 months postoperatively in 61.5% of studies, and return to cutting and pivoting sports 6 to 9 months postoperatively in 69.2% of studies. A MCID was reached for subjective International Knee Documentation Committee scores at 6, 12, and 24 months follow-up and Lysholm knee score at 24 months follow-up. An improvement in outcomes was most notably between 6 and 12 months postoperatively. There was a total of 31 complications (5.89%) and included graft rerupture (2.47%), loss of extension of 1° to 10° (1.14%), and cartilage or meniscus injuries on the operated knee (0.760%). Complications related to the surgical technique were not reported. The AIT for ACLR shows potential as a minimally invasive approach given the low graft failure rates and short-term improvements in knee function and stability, pain and patient important outcomes from this approach. Comparative studies with large sample sizes and a long-term follow-up are required to assess the proposed advantages of this technique. This is a Level IV study.
A patient with lower gastrointestinal bleeding: common history, very uncommon cause, minimally invasive treatment
Authors: Lock Guntram , Daniels Thies , Kock Lars 
Published: February 2018

AbstractAn 81-year-old patient with significant cardiac comorbidities, a history of sigmoid resection 6 years ago, and iliac bypass surgery 19 years ago presented with mild hematochezia for the previous 3 days. While hemodynamically stable at first, he developed massive bleeding during preparation for colonoscopy and underwent a short course of cardiopulmonary resuscitation. Colonoscopy revealed no active bleeding but a protuberance of the colonic wall and a coagulation clot. In ultrasonography immediately after endoscopy, a large aneurysm was diagnosed and diagnosis of an iliaco-colonic fistula was assumed. CT scan demonstrated a large pseudoaneurysm of the distal anastomosis after iliaco-iliac bypass. With endovascular treatment, the original lumen of the iliac artery could be recanalized, and 2 covered stents were placed to cover both anastomosis of the prosthetic bypass leading to a complete shutdown of bypass perfusion. A double-barreled transversostoma was established to minimize contamination of the aneurysmal sac. Seven months after these procedures, the patient is well and free of infection.Though aorto- or iliaco-colonic fistula after aortic or iliac surgery are very rare, endoscopists should be aware of their possibility. A high index of clinical suspicion in patients with prior abdominal vascular bypass surgery should prompt rapid imaging studies, possibly before endoscopy. In critically ill patients, endovascular treatment may be a suitable alternative and result in a favorable outcome.

Abstract
Aim The association of increased resistin levels in chronic kidney disease with diabetic nephropathy has not yet been clarified. Our aim was to analyze the relationship between serum resistin levels and various diabetic microvascular complications in patients.
Methods A total of 83 patients were enrolled in this cross-sectional study. The subjects were divided into 3 groups: 27 patients with type 2 diabetes mellitus (T2DM) having no diabetic retinopathy (DRP) or microalbuminuria and having normal renal function were included in Group-1, 28 patients with T2DM having DRP and normal renal function in Group-2, and 28 patients with T2DM with DRP and microalbuminuria and an estimated glomerular filtration rate (eGFR) of<60 ml/min/1.73 m2 in Group-3. Serum resistin levels were analyzed by enzyme-linked immunosorbent assay.
Results The mean age of the patients [46 female (55.4%)] was 54.8±9.1 years. The resistin level in Group-3 was significantly higher than in Group-1 and Group-2 (p<0.001).However the resistin level was not different between Group-1 (without microvascular complications) and Group-2 (with microvascular complications). The resistin level was found to be correlated negatively with eGFR (r=−0.459; p<0.001) and albumin (r=−0.402; p<0.001), and positively with high-sensitivity C-reactive protein (hs-CRP) (r=0.366; p=0.001). In multivariate analysis, it was observed that eGFR and hs-CRP were independent determinants of plasma resistin level.
Conclusion The main determinants of resistin level in patients with T2DM are the level of renal function and inflammation rather than presence of microvascular complications, obesity and insulin resistance.

Published: February 2018

Abstract
Purpose Neuropathy of the intermediate (IFCN) and medial femoral cutaneous nerve (MFCN) is a potential iatrogenic complication of thigh surgery and its diagnosis is limited. This study aimed to evaluate the possibility of the visualization and diagnostic assessment of the IFCN and MFCN with high-resolution ultrasound (HRUS).
Materials and Methods In this study, HRUS with high-frequency probes (15 – 22MHz) was used to locate the IFCN and the MFCN in 16 fresh cadaveric lower limbs. The correct identification of the nerves was verified by ink-marking and consecutive dissections at sites correlating to nerve positions (R1 – 3), namely, the origin, the mid portion, and the distal portion, respectively. 12 cases with suspected IFCN and MFCN lesions referred to our clinic for HRUS examinations were also assessed.
Results Anatomical dissection confirmed the correct identification of the IFCN in 16/16 branches at all of the different locations (100 %). MFCN was correctly identified at R1 + 3, in all cases (16/16; 100 %), and in 14/16 cases (88 %) at (R2). 12 cases of patients with IFCN and MFCN pathologies (all of iatrogenic origin) were identified. 9 instances of structural damage were visible on HRUS, and all pathologies were confirmed by almost complete resolution of symptoms after selective HRUS-guided blocks with 0.5 – 1 ml lidocaine 2 %.
Conclusion This study confirms that the IFCN and the MFCN can be reliably visualized with HRUS throughout the course of these nerves, both in anatomical specimens and in patients.

AbstractThe mechanisms underlying velocity-specific decreases in torque production during eccentric muscle actions remain unclear. Therefore, the purpose of the present study was to examine electrical efficiency at 60 and 180°·s
−1 during fatiguing, maximal eccentric isokinetic muscle actions of the leg extensors. Thirteen men visited the lab on two occasions and randomly performed 30 repeated maximal eccentric isokinetic muscle actions of the leg extensors at 60 and 180°·s

¹ through a 90° range of motion. Polynomial regression analyses and separate repeated measures ANOVAs were used to examine the composite patterns of responses for electromyographic amplitude, eccentric torque, and electrical efficiency across the 60 and 180°·s
−
¹ protocols. Eccentric torque remained unchanged across the 30 maximal eccentric muscle actions performed at 60 and 180°·s
−1. Electromyographic amplitude and electrical efficiency, however, increased linearly across the 180°·s
−1 protocol, but there were no changes for either electromyographic amplitude or electrical efficiency during the 60°·s
−1 fatiguing protocol. These findings indicated that performing eccentric muscle actions at a fast velocity (i. e., 180°·s
−1) was characterized by greater efficiency (i. e., decreased electrical efficiency) compared to eccentric muscle actions performed at a slow velocity (i. e., 60°·s
−1). Thus, it is possible that eccentric muscle actions performed at fast velocities are more robust to fatigue due, in part, to greater efficiency compared to slow-velocity eccentric muscle actions.
Die ökonomische Herausforderung der zentralisierten Behandlung von Patienten mit periprothetischen Infektionen

Published: February 2018

Zusammenfassung
Einleitung Die tiefe Infektion ist eine der schwersten Komplikationen der Endoprothetik. Die korrekte Diagnose und adäquate Therapie stellen eine enorme interdisziplinäre Herausforderung dar. Die notwendige Interdisziplinarität und Komplexität der Behandlung erfordert die Therapie in Zentren. Problematisch sind jedoch die hohen Kosten, die bisher noch kaum analysiert und diskutiert wurden. Das Ziel dieser Arbeit ist es daher, die Kosten innerhalb eines Behandlungsjahres in einer auf die Behandlung periprothetischer Infektionen spezialisierten Abteilung den Erlösen gegenüberzustellen.
Methodik Es erfolgte eine retrospektive Auswertung der im Jahr 2015 in unserem Centrum für Septische Chirurgie stationär behandelten Patienten anhand der Daten aus dem Krankenhausinformationssystem und des Klinikcontrollings. Die demografischen Daten, die Diagnosen, die Krankenhausverweildauer, die Anzahl der operativen Eingriffe und das Erregerspektrum wurden erfasst und die Kosten der Behandlung ermittelt. Diese wurden den DRG-Erlösen gegenübergestellt.
Ergebnisse Insgesamt wurden 281 Patienten im Jahr 2015 aufgrund einer Infektion des muskuloskeletalen Systems behandelt, davon 144 Fälle mit einer periprothetischen Infektion des Knie- oder Hüftgelenks (Verhältnis 1,5 : 1). Die durchschnittliche Verweildauer lag bei 16 Tagen, die mittleren Behandlungskosten pro Tag und Patient bei ca. 820 €. Die Gesamtkosten der 281 Behandlungen betrugen 3,3 Mill. € wovon lediglich 2,7 Mill. durch DRG-Erlöse gedeckt waren (Unterdeckung ca. − 20%). Dies entsprach einem Defizit von 633 000 €, bei einer mittleren Unterdeckung pro Behandlungsfall von 2300 €. Die Unterdeckung war bei Patienten mit einer infizierten Hüft-TEP im Mittel 5-mal (− 8585 €) so hoch wie das Defizit für einen Patienten mit infizierter Knieendoprothese (− 1638 €). Die wesentlichen Ursachen für die hohen Behandlungskosten waren die Liegedauer, Mehrfacheingriffe und die Besiedlung mit isolationspflichtigen Keimen.
Zusammenfassung Die zunehmende Zahl periprothetischer Infektionen erfordert die interdisziplinäre Behandlung in Zentren. Die nicht durch das DRG-System gedeckten Kosten verhindern jedoch eine solche hochspezialisierte Behandlung. Einhergehend damit ist ein Qualitätsverlust in der Behandlung. Hier besteht dringender gesellschaftlicher Diskussions- und Lösungsbedarf.
Vascular Anomalies (Part II): Interventional Therapy of Peripheral Vascular Malformations
Authors: Müller-Wille René , Wildgruber Moritz , Sadick Maliha , Wohlgemuth Walter 
Published: February 2018

Background The International Society for the Study of Vascular Anomalies (ISSVA) categorizes vascular anomalies into vascular tumors and vascular malformations. Vascular malformations are further divided into slow-flow (venous, lymphatic, and capillary malformation) and fast-flow malformations (arteriovenous malformation and arteriovenous fistula). This interdisciplinary classification has therapeutic implications.
Methods The objective of this article is to provide concise information about the current terminology and treatment strategies of peripheral vascular malformations, based on the currently available literature, with a focus on interventional therapy of venous malformations (VM), lymphatic malformations (LM), arteriovenous malformations (AVM) and arteriovenous fistulae (AVF).
Results and Conclusion Accurate classification is crucial for appropriate therapy of peripheral vascular malformations. Modern imaging technologies and refined interventional treatment strategies are now central parts in the multidisciplinary management of these patients. Slow-flow and fast-flow vascular malformations can be treated successfully by percutaneous sclerotherapy and endovascular embolotherapy as first-line interventions.

Abstract

BACKGROUND
During the past 4 decades, the highest worldwide blood pressure (BP) levels have shifted from high-income countries to low- and middle-income countries. We investigated the association of intragenerational social mobility with changes in BP and also with the incidence of hypertension over a 4-year follow-up.

METHODS
Data for 6,529 baseline participants from ELSA-Brasil born between 1938 and 1975 were used. Based on a social mobility matrix, occupational social mobility was defined as the change in occupational social class between participants’ first occupation and current occupation (stable high; upward; downward; stable low). Incident hypertension was defined as systolic blood pressure (SBP) ≥ 140 mm Hg or diastolic blood pressure (DBP) ≥ 90 mm Hg or use of antihypertensive medication. Hypertensive participants at baseline were excluded. Mixed effects regression models were used.

RESULTS
Compared to the stable high group, the downwardly mobile group showed a higher increase over time in both SBP (β = 1.49, 95% CI 0.60; 2.37) and DBP (β = 0.96, 95% CI 0.32; 1.59) after adjustments for background characteristics and also proximal risk factors such as health-related behaviors and body mass index as time-dependent covariates, and diabetes. In contrast, upward mobility had no influence on BP changes (β = 0.67, 95% CI −0.07; 1.41 for SBP, and β = 0.47, 95% CI −0.05; 1.00 for DBP). Social mobility was not associated with the incidence of hypertension.

CONCLUSIONS
We showed socioeconomic inequalities in BP progression over the life course. The longitudinal changes in BP varied by social mobility groups in the context of low- and middle-income countries, where high BP has become most prevalent.
Memory for Serial Order in Alzheimer’s Disease and Vascular Dementia: A Competitive Queuing Analysis
Authors: Rhodes Emma , Lamar Melissa , Libon David J , Giovannetti Tania 
Published: February 2018

Abstract

Objective
Competitive Queuing (CQ) models of memory for serial order comprise two layers: parallel planning where target items are activated and competitive choice where serial order is specified. The application of CQ models regarding healthy and pathological aging has received little attention.

Method
Participants included patients with Alzheimer’s disease (AD; n = 26), vascular dementia (VaD; n = 29), and healthy controls (HC; n = 35). Memory for serial order in the visual domain was assessed using the Object Span Task, where participants briefly viewed then drew a sequence of four figures. Percent correct and total errors (omissions, intrusions, repetitions, transpositions) were computed for each serial position.

Results
Significant primacy effects were detected in each group. AD and VaD participants were less accurate and showed more omission and between-trial repetition errors than HC (HC &lt; AD = VaD, p &lt; .05). VaD participants produced more transposition and intrusion errors than the AD and HC groups (HC &lt; AD &lt; VaD, p &lt; .05). A group × position interaction was significant for omissions (p &lt; .05), with AD and VaD participants producing more omissions in later serial positions (SP1 &lt; SP2 &lt; SP3 &lt; SP4, all p values &lt; .05).

Conclusions
Analysis of accuracy and errors by serial position identified unique patterns of performance across groups that suggest involvement of distinct layers of response activation and selection. Serial order difficulties in AD may be due to weakened activation of task items affecting later serial positions, whereas poor performance in VaD may be due to weakened activation plus interference from extraneous stimuli at all serial positions.
