Abstract
BACKGROUND AND OBJECTIVES Communicating the amount and effects of ionizing radiation to patients prior to an examination using x‑rays is associated with challenges: first, calculating the expected dose prior to the examination and, second, quantifying and illustrating cancer risks. Analogies, such as comparing radiation exposure to accident risks, have limitations and may evoke unease. This study explores and compares two new approaches to discuss radiation exposure from common clinical examinations with patients: effective dose and exposure based on radioactive potassium-40 intake from the ingestion of bananas, the banana equivalent dose (BED). MATERIALS AND METHODS The effective doses of the diagnostic reference levels (DRL) for computed tomography (CT) and X-ray examinations in adults were calculated using mean conversion factors for specific anatomic body regions. For the BED calculation of the diagnostic reference levels, the radiation dose from a conventional banana ingested over 50 years per becquerel was calculated. The outcomes were juxtaposed against an equivalent number of bananas and its respective radiation doses. RESULTS The calculated doses, namely effective dose and BED, of the German DRL can serve as a reliable metric to discuss radiation exposure from medical imaging with patients prior to an examination. CONCLUSION This is the first study to calculate the effective doses of the current DRL and to compare these with the pseudoscientific unit BED. While the BED serves as an interesting illustration to metaphorize radiation exposure, it is recommended to use the calculated effective dose of the DRL as the basis for educational consultations with patients.

Abstract
BACKGROUND Pathogens causing infections are in many cases transmitted via the hands of personnel. Thus, hand antisepsis has strong epidemiological evidence of infection prevention. Depending on various factors, hand antisepsis adherence ranges between 9.1% and 85.2%. AIM To evaluate a new transponder system that reminded medical staff to use an alcohol-based hand rub based on indication by giving real-time feedback, to detect hand antisepsis adherence. METHODS The monitoring system consisted of three components: a portable transponder detecting alcohol-based hand rub and able to give feedback; a beacon recognizing entries to and exits from the patient's surroundings; and a sensor placed at the hand-rub dispensers to count the number of hand rubs. With these components, the system provided feedback when hand antisepsis was not conducted although it was necessary according to moments 1, 4, and 5 of hand antisepsis. Adherence was measured in two use-cases with five phases, starting with the baseline measurement followed by intervention periods and phases without intervention to test the sustainability of the feedback. FINDINGS Using the monitoring system, hand antisepsis adherence was increased by up to 104.5% in comparison to the baseline measurement. When the intervention ceased, however, hand antisepsis adherence decreased to less than or equal to the baseline measurement. CONCLUSION A short-term intervention alone is not sufficient to lead to a long-term change in hand antisepsis adherence. Rather, permanent feedback and/or the integration in a multi-modal intervention strategy are necessary.

Abstract
Four-wheeled walkers or rollators are often used to assist older individuals in maintaining an independent life by compensating for muscle weakness and reduced movement stability. However, limited biomechanical studies have been performed to understand how rollator support affects posture and stability, especially when standing up and sitting down. Therefore, this study examined how stability and posture change with varying levels of rollator support and on an unstable floor. The aim was to collect comprehensive baseline data during standing up and sitting down in young participants. In this study, 20 able-bodied, young participants stood up and sat down both 1) unassisted and assisted using a custom-made robot rollator simulator under 2) full support and 3) touch support. Unassisted and assisted performances were analyzed on normal and unstable floors using balance pads with a compliant surface under each foot. Using 3D motion capturing and two ground-embedded force plates, we compared assistive support and floor conditions for movement duration, the relative timing of seat-off, movement stability (center of pressure (COP) path length and sway area), and posture after standing up (lower body sagittal joint angles) using ANOVA analysis. The relative event of seat-off was earliest under full support compared to touch and unassisted conditions under normal but not under unstable floor conditions. The duration of standing up and sitting down did not differ between support conditions on normal or unstable floors. COP path length and sway area during both standing up and sitting down were lowest under full support regardless of both floor conditions. Hip and knee joints were least flexed under full support, with no differences between touch and unassisted in both floor conditions. Hence, full rollator support led to increased movement stability, while not slowing down the movement, during both standing up and sitting down. During standing up, the full support led to an earlier seat-off and a more upright standing posture when reaching a stable stance. These results indicate that rollator support when handles are correctly aligned does not lead to the detrimental movement alterations of increased forward-leaning. Future research aims to verify these findings in older persons with stability and muscle weakness deficiencies.

Abstract
Background A potential benefit of electronic health records (EHRs) is that they could potentially save clinician time and improve documentation by auto-generating the history of present illness (HPI) in partnership with patients prior to the clinic visit. We developed an online patient portal called AEGIS (Automated Evaluation of Gastrointestinal [GI] Symptoms) that systematically collects patient GI symptom information and then transforms the data into a narrative HPI that is available for physicians to review in the EHR prior to seeing the patient. Objective This study aimed to compare whether use of an online GI symptom history taker called AEGIS improves physician-centric outcomes vs usual care. Methods We conducted a pragmatic controlled trial among adults aged ≥18 years scheduled for a new patient visit at 4 GI clinics at an academic medical center. Patients who completed AEGIS were matched with controls in the intervention period who did not complete AEGIS as well as controls who underwent usual care in the pre-intervention period. Of note, the pre-intervention control group was formed as it was not subject to contamination bias, unlike for post-intervention controls. We then compared the following outcomes among groups: (1) documentation of alarm symptoms, (2) documentation of family history of GI malignancy, (3) number of follow-up visits in a 6-month period, (4) number of tests ordered in a 6-month period, and (5) charting time (difference between appointment time and time the encounter was closed). Multivariable regression models were used to adjust for potential confounding. Results Of the 774 patients who were invited to complete AEGIS, 116 (15.0%) finished it prior to their visit. The 116 AEGIS patients were then matched with 343 and 102 controls in the pre- and post-intervention periods, respectively. There were no statistically significant differences among the groups for documentation of alarm symptoms and GI cancer family history, number of follow-up visits and ordered tests, or charting time (all P>.05). Conclusions Use of a validated online HPI-generation portal did not improve physician documentation or reduce workload. Given universal adoption of EHRs, further research examining how to optimally leverage patient portals for improving outcomes are needed.

Abstract
AIMS Investigate the involvement of the histaminergic projections from tuberomammillary nucleus (TMN) to the spinal cord in the modulation of nociception and peripheral edema in a model of monoarthritis. MAIN METHODS Subacute monoarthritis was induced by an intraarticular injection of carrageenan followed by LPS 72 h later. Disability and joint edema were assessed at the 3rd hour after LPS and at every hour up to 6 h. KEY FINDINGS Intrathecal administration of histamine potentiated joint incapacitation and edema, while the H1R antagonist cetirizine decreased both. The H3R agonist immepip decreased both incapacitation and edema, while the H3R antagonist thioperamide had the opposite effect. The microinjection of glutamate into the ventral TMN (vTMN) caused an increase of incapacitation and articular edema, whereas the blockade of this nucleus by cobalt chloride inhibited both parameters. Intrathecal administration of cetirizine prevented the increase of incapacitation and joint edema caused by glutamate microinjection into the vTMN. Similarly, an intrathecal injection of the NKCC1 cotransporter inhibitor bumetanide prevented the effects of glutamate microinjection into the vTMN, whereas coadministration of histamine with bumetanide only inhibited the potentiation of joint edema. A microinjection of orexin B into the vTMN potentiated incapacitation and joint edema, while coadministration of the OX1/2 receptor antagonist almorexant with orexin B did not. SIGNIFICANCE These data support the notion that TMN participates in the modulation of a peripheral inflammatory process by means of histaminergic projections to the spinal cord, and the hypothalamus may trigger TMN activation by means of glutamate and orexin.

Abstract
PURPOSE The consolidation of the acromioclavicular (AC) and coracoclavicular (CC) ligament complex after arthroscopically assisted stabilization of acute acromioclavicular joint (ACJ) separation is still under consideration. METHODS Fifty-five consecutive patients after arthroscopically assisted double-CC-bundle stabilization within 14 days after acute high-grade ACJ separation were studied prospectively. All patients were clinically analysed preoperatively (FU0) and post-operatively (FU1 = 6 months; FU2 = 12 months). The structural MRI assessments were performed at FU0 (injured ACJ) and at FU2 bilateral (radiologic control group) and assessed separately the ligament thickness and length at defined regions for the conoid, trapezoid and the superior AC ligament. RESULTS Thirty-seven patients were assessed after 6.5 months and after 16.0 months. The 16-month MRI analysis revealed for all patients continuous ligament healing for the CC-complex and the superior AC ligament with in the average hypertrophic consolidation compared to the control side. Separate conoid and trapezoid strands (double-strand configuration) were detected in 27 of 37 (73%) patients, and a single-strand configuration was detected in 10 of 37 (27%) patients; both configurations showed similar CCD data. The ligament healing was not influenced by the point of surgery, age at surgery and heterotopic ossification. The clinical outcome was increased (FU0-FU2): Rowe, 47.7-97.0 pts.; TAFT, 3.9-10.6 pts.; NAS pain, 8.9-1.4 pts. (all P < 0.05). CONCLUSION The arthroscopically assisted double-CC-bundle stabilization within 14 days after acute high-grade ACJ separation showed 16 months after surgery sufficient consolidations of the AC and double-CC ligament complex in 73%.

Abstract
INTRODUCTION Cartilage defects of the knee remain a challenging problem in orthopedic surgery despite the ongoing improvements in regenerative procedures such as the autologous chondrocyte transplantation. Due to the lack of donor-site morbidity and the single-stage procedure cell-free scaffolds are an interesting alternative to cell-based procedures. But as currently mid- and long-term data are lacking, the aim of the present study was to present mid-term clinical, radiological and histological results of a cell-free collagen type I scaffolds for cartilage repair. MATERIALS AND METHODS Twenty-eight patients were followed prospectively. Clinical evaluation using patient-reported outcome measures (KOOS, IKDC; VAS for pain, Tegner score for activity) as well as radiologic evaluation of the repair tissue (MOCART) was performed at 1 year, 2 years and 5 years. Histologic evaluation of the repair tissue was done in case of revision surgery using the ICRS II score for human cartilage repair. RESULTS In these large cartilage defects with a mean defect size of 3.7 ± 1.9 cm2, clinical failure necessitating revision surgery was seen in 5 of 28 patients (18%). While the remaining patients showed good-to-excellent clinical results (KOOS, IKDC, VAS, Tegner), the radiologic appearance of the repair tissue showed a reduction of the MOCART score between the 2- and 5-year follow-up. Histologic evaluation of the repair tissue showed a cartilage-like appearance with no signs of inflammation or cell death but an overall medium tissue quality according to the ICRS II Score. CONCLUSION The use of this cell-free collagen type I scaffold for large defects showed increased wear of the repair tissue and clinical failure in 18% of cases at 5-year follow-up.

Abstract
PURPOSE Traumatic high-grade acromioclavicular joint (ACJ) separations can be surgically stabilized by numerous anatomic and non-anatomic procedures. The return to sport (Maffe et al. in Am J Sports Med 23:93-98, 1995] and remaining sport-associated impairments after acute ACJ stabilization has not yet been investigated. METHODS 73 consecutive athletes with acute high-grade ACJ separation were prospectively assigned into two groups (64.4% randomized, 35.6% intention-to-treat): open clavicular hook plate (cHP) implantation (GI) or arthroscopically assisted double double-suture-button (dDSB) implantation (GII). Patients were analyzed using shoulder sport-specific measurement tools for sport ability (ASOSS), sport activity (SSAS), and numerical analog scales: NASpain during sport, NASshoulder function in sport, and NASre-achievement of sport level. Four points of examination were established: preoperative evaluation (FU0) and first postoperative follow-up (FU1) at 6 months; FU2 at 12 months; and FU3 at 24 months after surgery. The control group (GIII) consisted of 140 healthy athletes without anamnesis of prior macro-injury or surgery. RESULTS After surgical stabilization, 29 of 35 athletes in GI (82.9%; 38.6 ± 9.9 years) and 32 of 38 in GII (82.9%; 38.6 ± 9.9 years) were followed up for 24 months (FU3) (loss 17.8%). All operated athletes showed significantly increased scores compared to FU0 (p < 0.05). Compared to GI, GII showed significantly superior outcome data for sporting ability as well as for NASre-achievement of sport level (p < 0.05). While GII re-achieved GIII-comparable SSAS and ASOSS levels, GI remained at a significantly inferior level. Athletes after ACJ injury of Rockwood grade IV/V and overhead athletes benefited significantly from the dDSB procedure. CONCLUSION The dDSB procedure enabled significantly superior sport-specific outcomes compared to the cHP procedure. Athletes after dDSB surgeries re-achieved the sporting ability and the sport activity levels of healthy athletes, whereas athletes after cHP implantation remained at significantly inferior levels. The more extensive dDSB procedure and the more restrictive rehabilitation are recommended for treatment of acute high-grade ACJ separations of functionally high-demanding athletes.

Abstract
INTRODUCTION MPFL reconstruction is widely and successfully used for treating patella instability, either as a standalone procedure or in combination. Although different techniques allow for MPFL reconstruction, the use of a free tendon graft is one of the most commonly used. The phenomenon of tunnel widening or tunnel enlargement is well described in ACL reconstruction, but so far only little effort has been put into evaluating this phenomenon after MPFL reconstruction. MATERIALS AND METHODS Patients who received an MPFL reconstruction with a free gracilis tendon graft were identified by review of patient files. Additional clinical examination and magnetic resonance imaging were performed to assess tunnel enlargement and clinical outcome. RESULTS Fifty-one knees of 49 patients (34 female, 17 male) with a mean follow-up of 3.0 ± 1.4 years were included in this study. Mean age at the time of surgery was 22.6 ± 8.5 years. Mean Tegner score decreased from preoperative 5.3 ± 2.0 to 4.0 ± 1.4 postoperative. Postoperative IKDC and Kujala scores were 74 ± 16 and 80 ± 15, respectively. Twenty-three patients showed a tunnel enlargement at follow-up examination. Of these 23 patients, 20 showed a tunnel that was positioned too proximal, whereas only 13 of the 28 patients showing no enlargement had a tunnel that was positioned too proximal (p = 0.0033). Interestingly, patients showing a tunnel enlargement at follow-up examination also showed significantly better Kujala (84 ± 12 vs. 75 ± 16; p = 0.03) and IKDC scores (80 ± 7 vs. 70 ± 19; p = 0.02) when compared to the non-enlarged group. CONCLUSION Tunnel enlargement after MPFL reconstruction with a free gracilis tendon graft seems to be connected to mechanical overload due to a proximal malposition of the femoral tunnel. Interestingly, this did not influence clinical outcome as patients with tunnel enlargement showed better Kujala and IKDC scores.

Abstract
Primary effusion lymphoma (PEL) is a distinct clinicopathological entity usually characterized by presentation as a lymphomatous body cavity effusion in the absence of solid tumor mass or dissemination during its clinical course. PEL can also rarely occur as a solid lymphoma involving nodal and extranodal sites and is referred to as extracavitary PEL. Here we report a unique case of extracavitary PEL in a 49-year-old HIV-seropositive patient who presented with vague abdominal pain and 20-lb weight loss. Esophagogastroduodenoscopy and colonoscopy revealed more than 100 broad-based intestinal polyps ranging from 2 mm to 3 cm in size, spreading from the duodenum to the rectum as a typical impression of "intestinal polyposis syndrome." Multiple biopsies demonstrated sheets of large lymphoid cells with characteristic features of extracavitary PEL with strong Kaposi sarcoma-associated herpesvirus/human herpesvirus 8 virus positivity by immunohistochemistry. Extracavitary PEL presenting as distinctive multiple lymphomatous polyposis as manifested in the case has not been described previously.

Abstract
BACKGROUND Musculoskeletal illnesses and injuries are among the most common ailments in the Federal Republic of Germany. In 2008 they generated costs of nearly 29 billion euros. Figures about their incidence and prevalence are necessary for a demand-oriented planning of future patient-centred care. METHOD Pseudonymised data of 3.8 million people insured by AOK Baden-Württemberg between 2008 and 2013 were evaluated. The diagnoses were assigned to nine injury groups. For outpatient care confirmed diagnoses were considered, and for inpatient care both primary and secondary diagnoses were considered. For all patients with structural knee injuries, it was evaluated whether they made use of one of five eligible treatment paradigms either in the quarter in which they were injured or in the following quarter. RESULTS 418,257 patients were treated in 2013 for at least one new-onset injury (10.9 % of all insurees); 86,783 insurees (2.3 % of all insurees) had a newly occurring knee injury. The vast majority of the patients were treated by specialist doctors. While magnetic resonance imaging clearly increased during the observation period, the incidence of surgical therapy did not change. Striking are the different age distributions regarding the types of injuries, with a high injury incidence amongst young men and a significant increase in injuries between 2008 and 2013, especially amongst women. CONCLUSION For the first time, the data quantify the knee injury incidences of a large cohort in Germany. They show which inpatient and outpatient health care services have been claimed and that an age- and gender-adapted prevention and an increased awareness are needed.

Abstract
BACKGROUND In humans geographical differences in the incidence and presentation of various cancers have been reported. However, much of this information has not been collected in veterinary oncology. AIM The purpose of this study was to determine if a geographic difference in progression free survival exists for dogs with lymphoma treated within the US. MATERIALS AND METHODS Medical records of 775 cases of canine lymphoma from 3 US regions (west, south and north), treated with CHOP chemotherapy, were retrospectively evaluated. Cases were collected from referral institutions and were required to have received at least one doxorubicin treatment and have follow up information regarding time to progression. RESULTS Significant differences in sex (p = 0.05), weight (p = 0.049), stage (p < 0.001), immunophenotype (p = <0.001), and number of doxorubicin doses (p = 0.001) were seen between regions. Upon univariate analysis, progression free survival (PFS) differed by region (p = 0.006), stage (p = 0.009), sub-stage (p = 0.0005), and immunophenotype (p = 0.001). A multivariable Cox regression model showed that dogs in the western region had a significantly shorter PFS when compared to the south and east. CONCLUSION PFS was significantly affected by stage, sub-stage and phenotype.

Abstract
Several studies have confirmed the neuromuscular effects of jaw motor activity on the postural stability of humans, but the mechanisms of functional coupling of the craniomandibular system (CMS) with human posture are not yet fully understood. The purpose of our study was, therefore, to investigate whether submaximum biting affects the kinematics of the ankle, knee, and hip joints and the electromyographic (EMG) activity of the leg muscles during bipedal narrow stance and single-leg stance. Twelve healthy young subjects performed force-controlled biting (FB) and non-biting (NB) during bipedal narrow stance and single-leg stance. To investigate the effects of FB on the angles of the hip, knee, and ankle joints, a 3D motion-capture system (Vicon MX) was used. EMG activity was recorded to enable analysis of the coefficient of variation of the muscle co-contraction ratios (CVR) of six pairs of postural muscles. Between FB and NB, no significant differences were found for the mean values of the angles of the ankle, knee, and hip joints, but the standard deviations were significantly reduced during FB. The values of the ranges of motion and the mean angular velocities for the three joints studied revealed significant reduction during FB also. CVR was also significantly reduced during FB for five of the six muscle pairs studied. Although submaximum biting does not change the basic strategy of posture control, it affects neuromuscular co-contraction patterns, resulting in increased kinematic precision.

Abstract
INTRODUCTION Muscular recovery of structural integrity after arthroscopic Bankart repair using the para- and trans-musculotendinous three-portal technique has not been investigated. MATERIALS AND METHODS Twenty-seven athletes [mean age 26.9 years, (group 1; G1)] were prospectively and longitudinally monitored after arthroscopic Bankart repair using the three-portal technique by magnetic resonance imaging (MRI) and specific clinical muscular testing. The muscular integrity was assessed at the subscapularis (SSC) for the para-tendinous anteroinferior portal, the supraspinatus (SSP) for the trans-tendinous suprabicipital portal, and the infraspinatus (ISP) for the trans-tendinous posterior portal. Muscular atrophy was assessed by standardized ratios of transverse and vertical diameters for the SSC and ISP, as defined by cross-sectional area ratios for the SSP. Fatty infiltration was assessed by signal intensity analysis for the upper and lower SSC, SSP, and upper ISP as a ratio with the lower ISP. These parameters were analyzed for pre-operative (T0), 1-year (T1), and 2-year status (T2), and compared to 27 healthy volunteers [mean age 29.4 years, (group 2, G2)]. RESULTS The structural integrity assessments were performed after 14.8 (T1) and 32.0 months (T2). The SSC analysis revealed no muscular impairments in the upper and lower portions between T0 and T2 or compared to G2. MRI analysis for SSP and ISP showed full muscular recovery without any changes between T0 and T2 or deficits compared to G2. The number of pre-operative dislocations had no influence on the muscular integrity. MR analysis detected signs of overuse syndrome in 15 % at T0, 41 % at T1, and 63 % at T2; 77, 22, and 26 % of patients at T0, T1, and T2, respectively, were symptomatic. CONCLUSIONS Arthroscopic Bankart repair using the three-portal technique prevents full muscular integrity for para-tendinous anteroinferior portals at the SSC, the trans-tendinous suprabicipital portal through the SSP, and the trans-tendinous portal through the ISP.

Abstract
OBJECTIVE This study aims to assess the test-retest reproducibility of specific spatio-temporal (foot placement, foot contact time) and dynamic (resultant horizontal and vertical ground reaction force) gait parameters of three different, everyday occurring, turning conditions. The subjects were tested at two subsequent days. Out of this setting the purpose of this study is to clarify, if turning locomotion is stable when performed at different test occurrences. METHODS Eight subjects completed three different daily occurring turning conditions along turns with a given walking velocity of 5 km/h (± 10%). Subjects had to complete the turns three times clockwise and counter clockwise. The measurements were recorded with a 3D motion analysis system (Vicon(®)) and two force sensitive platforms (AMTI(®)), connected to the motion analysis system. RESULTS The analysis yields for most of the parameters and turning conditions ICCs from good (r = 0.72; p = .06) to high (r = 0.96; p < .01) magnitude for the measured spatio-temporal and dynamic parameters. CONCLUSIONS Based on our findings it can be assumed that locomotion strategies, related to the measured gait parameters of common daily turning tasks, are stable and reproducible.

Abstract
Human posture is characterised by inherent body sway which forces the sensory and motor systems to counter the destabilising oscillations. Although the potential of biting to increase postural stability has recently been reported, the mechanisms by which the craniomandibular system (CMS) and the motor systems for human postural control are functionally coupled are not yet fully understood. The purpose of our study was, therefore, to investigate the effect of submaximum biting on postural stability and on the kinematics of the trunk and head. Twelve healthy young adults performed force-controlled biting (FB) and non-biting (NB) during bipedal narrow stance and single-leg stance. Postural stability was quantified on the basis of centre of pressure (COP) displacements, detected by use of a force platform. Trunk and head kinematics were investigated by biomechanical motion analysis, and bite forces were measured using a hydrostatic system. The results revealed that FB significantly improved postural control in terms of reduced COP displacements, providing additional evidence for the functional coupling of the CMS and human posture. Our study also showed, for the first time, that reductions in the sway of the COP were accompanied by reduced trunk and head oscillations, which might be attributable to enhanced trunk stiffness during FB. This physiological response to isometric activation of the masticatory muscles raises questions about the potential of oral motor activity as a strategy to reduce the risk of falls among the elderly or among patients with compromised postural control.

Abstract
The prevalence of rotator cuff lesions is age-dependent and up to 19-32 % for full-thickness ruptures and 13-32 % for partial-thickness lesions respectively. The therapy of partial-thickness ruptures should be considered in accordance with the articular, bursal or intratendinous location of the lesion. The therapy of full-thickness ruptures should be applied in accordance with topography and area of defect, retraction, atrophy and fatty infiltration. These parameters are considered to be important prognostic factors for the intraoperative repairability and the success of the surgery. Symptomatic or chronically progredient partial-thickness lesions as well as full-thickness lesions should generally be treated by means of surgical reconstruction. No current scientific consensus exists regarding improved clinical outcome data after the surgical approach in mini-open or arthroscopic technique. Both procedures should meet the requirements of the Gerber criteria for rotator cuff reconstruction: high primary stability, reduction of micro-movements, minimized approach associated morbidity and persisting stability to enable the fibroblastic tendon-to-bone healing. Current studies revealed a potential improvement of the tendon-to-bone healing by the application of several biologic augmentations. At the moment, these additive procedures can be applied in revision situations and for complex rotator cuff lesions with low tendon quality. No high-level in-vivo investigations concerning the human shoulder exist in the current literature that show evidence-based improvements by the additively applied biologic augmentations for rotator cuff repair.

Abstract
Cell-matrix interactions control outgrowth of mammary epithelium during puberty and pregnancy. We demonstrate here that the glycoprotein fibulin-2 (FBLN2) is strongly associated with pubertal and early pregnant mouse mammary epithelial outgrowth. FBLN2 was specifically localized to the cap cells of the terminal end buds during puberty and to myoepithelial cells during very early pregnancy (days 2-3) even before morphological changes to the epithelium become microscopically visible, but was down-regulated thereafter. Exposure to exogenous oestrogen (E2) or E2 plus progesterone (P) increased Fbln2 mRNA expression in the pubertal gland, indicating hormonal control. FBLN2 was co-expressed and co-localised with the proteoglycan versican (VCAN) and co-localised with laminin (LN), while over-expression of FBLN2 in HC-11 cells increased cell adhesion to several extracellular matrix proteins including LN and fibronectin, but not collagens. Mammary glands from Fbln2 knockout mice showed no obvious phenotype but increased fibulin-1 (FBLN1) staining was detected, suggesting a compensatory mechanism by other fibulin family members. We hypothesise that similar to embryonic aortic smooth muscle development, FBLN2 and VCAN expression alters the cell-matrix interaction to allow mammary ductal outgrowth and development during puberty and to enable epithelial budding during pregnancy.

Abstract
There is no widely accepted standard of care for canine anal sac apocrine gland adenocarcinoma (ASAGAC). Surgery alone is inadequate in many cases, but the benefit of adjuvant chemotherapy is not well established. The primary objective of this retrospective study was to evaluate the role of carboplatin chemotherapy in the post-operative management of ASAGAC. Seventy-four dogs with naturally occurring ASAGAC underwent surgery. Forty-four dogs received adjuvant carboplatin and 30 did not. Median overall survival (OS) was 703 days. Median time to progression (TTP) was 384 days. Only primary tumour size and lymph node metastasis at diagnosis significantly impacted the outcome. Differences in OS and TTP, between the dogs that received adjuvant carboplatin and those that did not, failed to reach statistical significance. Treatment of progressive disease, whilst not limited to chemotherapy, significantly prolonged the survival. This study shows that adjuvant carboplatin chemotherapy is well tolerated and may have a role in the management of dogs with ASAGAC.

Abstract
Robotic manipulanda are an established tool for the investigation of human motor control and learning. Potentially, robotic manipulanda could also be valuable in the investigation of skill learning in more natural movement tasks. Most current designs have been developed for studying dynamic learning and rehabilitation and are restricted to 2D space. However, natural upper limb movements take place in 3D space, sometimes with high underlying forces. In this paper, we introduce a robotic device, the BioMotionBot, that can be used in established applications of dynamic learning and rehabilitation but also enables the investigation of skill learning in more natural 3D movement tasks with large dynamic perturbations. The design of the BioMotionBot is based on a mechanism with hybrid serial and parallel kinematics. We first describe the BioMotionBot's mechanical design, the electronic components, the software structure and the control system. To investigate the performance of the BioMotionBot, its stiffness, endpoint mass, endpoint viscosity, haptic resolution, force depth and impedance ratio are evaluated. Additionally, we develop a detailed multi-body simulation model to validate aspects of the structure and behavior of the BioMotionBot. Finally, we present experimental data from a dynamic learning task in 2D and test a 3D scenario with virtual walls. Our results demonstrate that the BioMotionBot can be used for research in human motor learning and rehabilitation and also has potential for the investigation of skill learning in more natural 3D movement tasks.

Abstract
PURPOSE Conventionally, radiography studies revealed prolonged glenoidal drill hole visibilities with an unclear influence to the clinical outcome after arthroscopic Bankart repair using Poly-Laevo-Lactic-Acid (PLLA) anchors. The primary aim of the present study was the separated assessment of drill hole consolidation (DHC) and the concomitant osseous reaction (OR) of the glenoidal bio-degradation process in new specific magnetic resonance grading systems. In accordance with the specific DHC and the OR graduation, the clinical relevance was the secondary focus. METHODS Twenty-eight patients with arthroscopic Bankart repair using knotless PLLA anchors were prospectively followed and analyzed using a clinical scoring system (3, 6, 15 and 32 months). The T2-weighted OR and T1-weighted DHC were assessed using specific magnetic resonance imaging grading protocols (15 and 32 months). RESULTS Longitudinal assessments revealed successive clinical status improvements over time (32 months: Rowe 95.7 ± 3.8; Walch-Duplay 93.8 ± 6.6; Constant 93.9 ± 4.5; ASES 93.8 ± 6.9; DASH 28.6 ± 7.2; NAS(pain) 1.1 ± 1.3; NAS(function) 1.3 ± 1.4). The initial OR level regressed over the 15-32 month period while the DHC showed significant drill hole reductions (P < 0.05). The inferior glenoid revealed a significantly increased bio-degradation capacity (P < 0.05) with drill hole enlargements in 14.3%. Neither the OR nor the drill hole enlargements influenced the clinical status. In no case were clinical or radiologic signs for a foreign body reaction. CONCLUSION Knotless bio-anchors provide secure glenoidal fixation for Bankart repair without any specific clinical or MR evidence of an inflammatory response. The clinical status remained unaffected by the bio-degradation process. LEVEL OF EVIDENCE IV.

Abstract
Transforming growth factor beta (TGFbeta)-stimulated clone-22 domain family member 1 (TSC-22D1) has previously been associated with enhanced apoptosis in several cell systems. In an attempt to identify novel factors that are involved in the control of cell death during mammary gland involution, we found that the mRNA for isoform 2 of TSC-22D1 was highly upregulated 24 h after forced weaning, when a dramatic increase in cell death occurred, closely following the expression of the known inducer of cell death during involution, TGFbeta3. This was paralleled by strongly increased TSC-22D1 isoform 2 protein levels in the luminal epithelium. In contrast, RNA and protein expression levels of the isoform 1 of TSC-22D1 did not change during development. Whereas isoform 2 induced cell death, isoform 1 suppressed TGFbeta-induced cell death and enhanced proliferation in mammary epithelial cell lines. Furthermore, four distinct forms of isoform 2 protein were detected in the mammary gland, of which only a 15-kDa form was associated with early involution. Our data describe novel opposing functions of the two mammalian TSC-22D1 isoforms in cell survival and proliferation, and establish the TSC-22D1 isoform 2 as a potential regulator of cell death during mammary gland involution.

Abstract
INTRODUCTION The purpose of this study was to monitor the muscular changes regarding the isokinetic strength and torque pattern of the quadriceps femoris at the stable athlete's knee after meniscus tear refixation. MATERIALS AND METHODS Therefore 15 athletes (10 male, 5 female) performing recreational or competitional sports at least five times a week before injury were retrospectively examined in the average 2.5 years after isolated arthroscopic meniscus refixation using Inside Out technique. Next to function and sport activity focused scores the isokinetic peak torque (PT) and in the EMG have been analyzed compared to the uninjured knee. RESULTS The mean age was 31.26 years. The time between injury and surgery was in the average 13.7 days. According to our first results the data suggest a complete recovery of functional and muscular pattern after meniscus refixation at the stable athlete's knee. No significant EMG changes for quadriceps femoris were detectable. The PT was fully recovered. The functional and sport activity score analysis (Lysholm and Tegner score) showed no changes in the postoperative long-term follow up compared to the preinjured status. CONCLUSION Examining isokinetic PT and the EMG of the quadriceps femoris, these data show no side-to-side differences. Regarding the function and sports activity score system, the functionally high demand patients seem to profit by this procedure.
