In recent years, many studies have reported substantial populations of large galaxies with low surface brightness in local galaxy clusters. Various theories that aim to explain the presence of such ultra-diffuse galaxies (UDGs) have since been proposed. A key question that will help to distinguish between models is whether UDGs have counterparts in host haloes with lower masses, and if so, what their abundance as a function of halo mass is. We here extend our previous study of UDGs in galaxy clusters to galaxy groups. We measure the abundance of UDGs in 325 spectroscopically selected groups from the Galaxy And Mass Assembly (GAMA) survey. We make use of the overlapping imaging from the ESO Kilo-Degree Survey (KiDS), from which we can identify galaxies with mean surface brightnesses within their effective radii down to ~25.5 mag arcsec-2 in the r band. We are able to measure a significant overdensity of UDGs (with sizes reff ≥ 1.5 kpc) in galaxy groups down to M200 = 1012 M⊙, a regime where approximately only one in ten groups contains a UDG that we can detect. We combine measurements of the abundance of UDGs in haloes that cover three orders of magnitude in halo mass, finding that their numbers scale quite steeply with halo mass: NUDG(R < R200) ∝ M2001.11±0.07. To better interpret this, we also measure the mass-richness relation for brighter galaxies down to Mr* + 2.5 in the same GAMA groups, and find a much shallower relation of NBright(R < R200) ∝ M2000.78±0.05. This shows that compared to bright galaxies, UDGs are relatively more abundant in massive clusters than in groups. We discuss the implications, but it is still unclear whether this difference is related to a higher destruction rate of UDGs in groups or if massive haloes have a positive effect on UDG formation.

Published: August 2017

Purpose The primary objective of this study was to evaluate if the current mechanisms of preoperative counseling influence patients' expectations of shoulder surgery.
Methods Patients were asked to complete the Hospital for Special Surgery's (HSS) Shoulder Surgery Expectations Survey. The first survey was completed before the first appointment with one of four fellowship-trained shoulder surgeons. The second survey was completed after patients consented for surgery. Our analysis also included patient demographics and surgical factors.
Results A total of 41 patients completed the HSS Shoulder Surgery Expectations Survey before and after their first appointment with the surgeon during which they consented to shoulder surgery. Before seeing the surgeon, the mean HSS Shoulder Surgery Expectations score was 72.5. After seeing the surgeon and being consented for surgery, the mean HSS Shoulder Surgery Expectations score was 74.8. The mean change in HSS Shoulder Surgery Expectations score (+2.3) was not statistically significant (p value = 0.242). We did not find any significant correlations between patients' expectations and demographics or surgical factors. Total HSS Shoulder Surgery Expectations scores and change in scores were not statistically different between the four surgeons (p = 0.146).
Conclusion Patient expectations were not substantially altered after preoperative counseling. Further investigation is necessary to investigate factors correlated with expectations, the implication of unaltered expectations on the postoperative outcome, and methods for improving the preoperative counseling process.

Published: August 2017

AbstractWe present the case of a jugular foramen meningioma with predominantly intraluminal invasion of the transverse, sigmoid sinuses, jugular bulb, and internal jugular vein with venous occlusion in a 45-year-old woman. Magnetic resonance imaging (MRI) of the brain and conventional angiography were performed preoperatively and revealed a right-sided extra-axial dural-based mass in the jugular foramen. The surgical approach was a high cervical approach with exposure of the internal carotid artery, jugular vein, and cranial nerves IX to XII as well as a combined posterior temporo-basal and retrosigmoid craniotomy with mastoidectomy and posterior retrolabyrinthine petrosectomy. The transverse, sigmoid sinuses, jugular bulb, and superior internal jugular vein were removed en bloc, and the exophytic intradural tumor extension around cranial nerves IX, X, XI, and XII was resected subtotally. Postoperatively, the patient presented a transient right facial weakness (House-Brackmann II). MRI showed partial resection. This is the first case report of a jugular foramen meningioma with transverse and sigmoid sinuses invasion and jugular vein extension in the adult population.
Schwannom des Magens: seltene Differenzialdiagnose einer akuten oberen gastrointestinalen Blutung

Published: August 2017

ZusammenfassungSchwannome sind benigne Tumoren der Schwann-Zellen und manifestieren sich hauptsächlich am Körperstamm und im Bereich der Extremitäten. Gastrointestinale Schwannome sind extrem selten, treten am häufigsten im Magen auf und verlaufen meist asymptomatisch.Wir berichten über ein Schwannom des Magens, das sich durch Hämatemesis auf dem Boden einer akuten oberen GI-Blutung bei einem 51-jährigen Mann klinisch manifestierte. Die Endoskopie des oberen Gastrointestinaltrakts erbrachte eine submuköse Raumforderung des Magenfundus von ca. 7 cm Durchmesser. Die anschließende Endosonografie des Magens zeigte den Ursprung der Raumforderung in der 4. Wandschicht (Muscularis propria) bei klar abgrenzbaren Rändern. Der Ursprung in der 4. Schicht sowie die im Vergleich mit der Echogenität der regulären Muskelschichten bestehende Isoechogenität finden sich signifikant häufiger beim Schwannom des Magens als beim gastrointestinalen Stromatumor. Endoskopisch-bioptisch konnte präoperativ keine klare Diagnose erzielt werden. Wir führten die endoskopisch-laparoskopische Magen-Wedge-Resektion des Fundus durch (in Rendezvous-Technik). Die Diagnose eines Schwannoms erfolgte nach histopathologischer Untersuchung mit Immunhistochemie mit typischer Positivität für das S100-Antigen, ohne Zeichen der Malignität. Der postoperative Verlauf war unauffällig.Die Erstmanifestation eines Schwannoms des Magens mit gastrointestinaler Blutung ist in der Literatur mit ca. 14 % der Fälle eher selten und wird überwiegend mit okkultem Blut im Stuhl bzw. Meläna angegeben – im Gegensatz zu unserem Patienten mit akuter oberer gastrointestinaler Blutung.

ZusammenfassungNeben der Betrachtung der Individualmedizin hat die Sozialmedizin die sozialen Bezüge von Gesundheit und Krankheit im Fokus. Sie reflektiert in diesem Zusammenhang die Strukturen des gesamten Gesundheitssystems, dessen Funktionen und Funktionsdefizite. Sie befasst sich mit den spezifischen Wechselwirkungen zwischen Medizin und Gesellschaft und hat eine Brückenfunktion zu den klassischen Sozialwissenschaften 1. Von besonderem Interesse sind dabei die Schnittstellen in der sektoralen Versorgung. Die Arbeitsgruppe „Pflege“ des Fachbereichs „Praktische Sozialmedizin und Rehabilitation“ der Deutschen Gesellschaft für Sozialmedizin und Prävention, DGSMP, betrachtet wesentliche Schnittstellen in unserem sektoralen Versorgungssystem aus sozialmedizinischer Sicht in ihrer derzeitigen Funktion und Perspektive, v. a in Anbetracht der demografischen Herausforderungen der Zukunft. Von besonderer Bedeutung ist hierbei die Schnittstelle zwischen medizinischer und pflegerischer Versorgung im akutstationären und häuslichen Bereich sowie im Bereich der geriatrischen Versorgung einschließlich präventiver Maßnahmen. Mit diesem Beitrag soll eine Diskussion angeregt werden.

Abstract
This study investigated the effects of high-intensity ultrasound and glycosylation on the structural and interfacial properties of the Maillard reaction conjugates of buckwheat protein isolate (BPI). The covalent attachment of dextran to BPI was confirmed by examination of the Fourier-transform infrared spectra. Emulsifying properties of the conjugates obtained by ultrasound treatment were improved as compared to those obtained by classical heating. Structural feature analyses suggested that conjugates obtained by ultrasound treatment had less α-helix and more random coil, higher surface hydrophobicity and less compact tertiary structure as compared to those obtained by classical heating. The surface activity measurement revealed that the BPI–dextran conjugates obtained by ultrasound treatment were closely packed and that each molecule occupied a small area of the interface. Combination of ultrasonic treatment and glycosylation was proved to be an efficient way to develop new stabilizers and thickening agents for food in this study.

ABSTRACTExtracellular vesicles (EVs), including microvesicles and exosomes, mediate intercellular signalling which has a profound role in cancer progression and in the development of metastasis. Internalisation of EVs can prompt functional changes in the recipient cells, the nature of which depends on the molecular composition and the cargo of the EVs. We hypothesised that the metastatic stage of cancerous parent cells would determine the uptake efficacy and the subsequent functional effects of the respective cancer cell‐derived EVs. To address this question, we compared the internalisation of EVs derived from two metastatic site‐derived prostate cancer cell lines (PC‐3 and LNCaP), human telomerase reverse transcriptase immortalised primary malignant prostate epithelial cells (RC92a/hTERT), and a benign epithelial prostate cell line (PNT2). EVs isolated from the metastatic site‐derived PC‐3 and LNCaP cells were more efficiently internalised by the PC‐3 and PNT2 cells compared to the EVs from the primary malignant RC92a/hTERT cells or the benign PNT2 cells, as determined by high content microscopy, confocal microscopy, and flow cytometry. EV uptake was also influenced by the phase of the cell cycle, so that an increased EV‐derived fluorescence signal was observed in the cells at the G2/M phase compared to the G0/G1 or S phases. Finally, differences were also observed in the functions of the recipient cells based on the EV source. Proliferation of PNT2 cells and to a lesser extent also PC‐3 cells was enhanced particularly by the EVs from the metastatic‐site‐derived prostate cancer cells in comparison to the EVs from the benign cells or primary cancer cells, whereas migration of PC‐3 cells was enhanced by all cancerous EVs.
The Impact of Crowding on Calorie Consumption
Authors: Hock Stefan J , Bagchi Rajesh 
Published: August 2017

AbstractConsumer behavior is often influenced by subtle environmental cues, such as temperature, color, lighting, scent, or sound. We explore the effects of a not-so-subtle cue—human crowding—on calorie consumption. Although crowding is an omnipresent factor, it has received little attention in the marketing literature. We present six studies showing that crowding increases calorie consumption. These effects occur because crowding increases distraction, which hampers cognitive thinking and evokes more affective processing. When consumers process information affectively, they consume more calories. We show the specific reason for the increase in calories. When given a choice between several different options, people select and eat higher-calorie items, but when presented with only one option, people eat more of the same food item. We document this process, rule out alternative explanations, and discuss theoretical and managerial implications.

Subclinical hypothyroidism (SCH) during pregnancy has been associated with impaired fetal neuropsychological development. Several organizations recommend treatment of subclinical thyroid dysfunction, although the Controlled Antenatal Thyroid Screening study found mothers who were treated with levothyroxine for hypothyroidism or hypothyroxinemia did not have children with improved cognitive function compared with controls.

Published: August 2017

Abstract

Background
Combination antipsychotics (CAs) are prescribed in schizophrenia despite limited evidence of efficacy. To explore the effect of switching from CA to monotherapy, we performed an exploratory analysis of the PROACTIVE (Preventing Relapse in Schizophrenia: Oral Antipsychotics Compared with Injectables: Evaluating Efficacy) study data, in which 305 patients with schizophrenia and schizoaffective disorder were followed for 30 months after randomization to long-acting injectable (LAI) risperidone or second-generation oral antipsychotic (OA).

Methods
Patients who entered the PROACTIVE study on CA (n = 50), LAI (n = 20), or OA (n = 206) were compared in terms of time to relapse and clinical measures.

Findings
The OA group had significantly fewer hospitalizations than the CA group (P = 0.009) at baseline. In the CA group, 68% patients relapsed versus 53% in the LAI, and 52% in the OA groups. Although there was no significant difference in the relapse rate among groups on χ2 test (χ2 = 3.85, P = 0.146), the log-rank test showed a significant difference among the groups in time to first relapse (χ2 = 6.81, P = 0.033), with significantly longer time to relapse in the OA group (mean, 562.8 days) than in the CA group (mean, 409.5; P = 0.011). The LAI group's mean time to first relapse (594 days) was not significantly different from the other groups. However, after adjusting for number of hospitalizations, group was no longer significant (hazard ratio, 1.541; P = 0.052).

Implications
Based on our exploratory analysis, taking antipsychotic combinations predicts earlier relapse and calls for additional treatment guidance in schizophrenia.
Lidocaine spray as a local analgesic for intravenous cannulation: a randomized clinical trial
Authors: Datema Joris , Veldhuis Jeroen , Bekhof Jolita 
Published: August 2017

Objectives
Lidocaine spray is an effective analgesic of mucous membranes. Lidocaine spray is also used during intravenous (i.v.) cannulation, especially in children. However, the analgesic effect of lidocaine spray during i.v. cannulation has not been studied. We aimed to assess the analgesic effectiveness of lidocaine spray during i.v. cannulation.

Methods
We conducted a randomized, double-blinded, placebo-controlled trial in seventeen healthy adults who received an i.v. cannulation in the right and left elbow, respectively, where the order of application of 60 mg lidocaine spray (Xylocaine 10% pump spray) or placebo spray (chlorhexidine gluconate 0.5% in 70% alcohol base) before i.v. cannulation was randomized. Thus, each participant had an i.v. cannulation in both arms: one with lidocaine spray and the other with placebo spray. The primary outcome was pain intensity assessed by a 100 mm Visual Analogue Scale. The secondary outcomes were adverse events, success rate of i.v. cannulation and the degree of difficulty of i.v. cannulation as estimated by the nurse performing the i.v cannulation.

Results
The pain score (Visual Analogue Scale) during i.v. cannulation was 18.0 mm (interquartile range: 5.0–34.5 mm) after lidocaine application and 21.0 mm (interquartile range: 11.0–30.5) after placebo application. These scores were not significantly different (95% confidence interval: −9.0–11.0, P=0.698). No adverse events occurred and all i.v. cannulations were successful at first attempt.

Conclusion
Local administration of lidocaine is not effective in reducing pain during i.v. cannulation.
A Multifaceted Model to Evaluate Interprofessional Education in Clinical Nurse Specialist Programs
Authors: Becker Heather , Timmerman Gayle M. , Delville Carole , Seo EunJin 
Published: August 2017

Purpose:
Preparing students to engage in team-based healthcare is a major focus of clinical nurse specialist (CNS) education programs. A robust evaluation plan is needed to monitor achievement of key outcomes in this complex undertaking.

Description:
Informed by the work of Kirkpatrick and Stufflebeam, an evaluation model that incorporates multiple information sources about process and outcomes related to interprofessional (IP) education is proposed.

Outcome:
Improvements in scores on attitude and competency measures suggest that the program had the desired effects on students' attitudes and self-efficacy for IP collaboration and was validated by faculty clinical observations of IP communication and teamwork. Moreover, students indicated at both graduation and at 1-year follow-up surveys that they were prepared to function on IP teams, providing further evidence that the clinical nurse specialist (CNS) program prepared them in this key area of nursing practice.

Conclusion:
The evaluation plan guided the collection of quantitative and qualitative information that faculty could use to refine the CNS program. Congruent with the CNS role as change agents, future model refinements should incorporate systems change activities.
