Abstract
PURPOSE Evaluation of the clinical data 3 months after implantation of a new diffractive multifocal intraocular lens (MIOL) with a reduced near add power of + 2.75 D. METHODS In a prospective study, patients who underwent cataract surgery or refractive lens exchange with implantation of an MIOL (Tecnis ZKB00, Abbott Medical Optics, Santa Ana, California, USA) were included. Three months postoperative corrected and uncorrected visual acuities at different distances were measured and evaluated. Those patients that underwent bilateral MIOL implantation additionally filled out a questionnaire 3 months postoperatively. RESULTS Between October 2013 and August 2014, 115 eyes of 62 patients were implanted with the ZKB00 IOL. Mean postoperative refractions were - 0.27 ± 0.44 D for the spherical equivalent, respectively. Mean binocular CDVA was - 0.01 ± 0.3 logMAR with a mean binocular UDVA of 0.06 ± 0.08 logMAR. For near distance in 40 cm, an UNVA of 0.07 ± 0.10 logMAR three months postoperatively was measured. CONCLUSION The ZKB00 IOL belongs to a group of novel MIOL with an increased intermediate visual performance. Our study shows good visual acuity at all distances, as well as a high rate of satisfaction and subjectively good image quality.

Abstract
STUDY QUESTION Which essential items should be recorded before, during and after endometriosis surgery and in clinical outcome based surgical trials in patients with deep endometriosis (DE)? SUMMARY ANSWER A DE surgical sheet (DESS) was developed for standardized reporting of the surgical treatment of DE and an international expert consensus proposal on relevant items that should be recorded in surgical outcome trials in women with DE. WHAT IS KNOWN ALREADY Surgery is an important treatment for symptomatic DE. So far, data have been reported in such a way that comparison of different surgical techniques is impossible. Therefore, we present an international expert proposal for standardized reporting of surgical treatment and surgical outcome trials in women with DE. STUDY DESIGN, SIZE, DURATION International expert consensus based on a systematic review of literature. PARTICIPANTS/MATERIALS, SETTING, METHODS Taking into account recommendations from Consolidated Standards of Reporting Trials (CONSORT), the Innovation Development Exploration Assessment and Long-term Study (IDEAL), the Initiative on Methods, Measurement and Pain Assessment in Clinical trials (IMMPACT) and the World Endometriosis Research Foundation Phenome and Biobanking Harmonisation Project (WERF EPHect), a systematic literature review on surgical treatment of DE was performed and resulted in a proposal for standardized reporting, adapted by contributions from eight members of the multidisciplinary Leuven University Hospitals Endometriosis Care Program, from 18 international experts and from audience feedback during three international meetings. MAIN RESULTS AND THE ROLE OF CHANCE We have developed the DESS to record in detail the surgical procedures for DE, and an international consensus on pre-, intra- and post-operative data that should be recorded in surgical outcome trials on DE. LIMITATIONS, REASONS FOR CAUTION The recommendations in this paper represent a consensus among international experts based on a systematic review of the literature. For several items and recommendations, high-quality RCTs were not available. Further research is needed to validate and evaluate the recommendations presented here. WIDER IMPLICATIONS OF THE FINDINGS This international expert consensus for standardized reporting of surgical treatment in women with DE, based on a systematic literature review and international consensus, can be used as a guideline to record and report surgical management of patients with DE and as a guideline to design, execute, interpret and compare clinical trials in this patient population.

Abstract
Actively stabilized, simultaneous spatial and temporal coherent beam combination is a promising power-scaling technique for ultrafast laser systems. For a temporal combination based on optical delay lines, multiple stable states of operation arise for common stabilization techniques. A time resolved Jones' calculus is applied to investigate the issue. A mitigation strategy based on a temporally gated error signal acquisition is derived and demonstrated, enabling to stabilize laser systems with arbitrary numbers of amplifier channels and optical delay lines.

Abstract
OBJECTIVES Medical and life-style factors are associated with malnutrition in older adults. This study assessed the presence of these risk factors in limited-resource, community-dwelling older adults to inform the development of a nutrition education interventions. DESIGN Quantitative descriptive study. SETTING A total of 24 randomly selected congregate nutrition sites (where limited-resource older adults can receive one hot meal/day, five days/week) in the rural state of South Carolina, USA. PARTICIPANTS Data were collected from 477 older adults (of the 407 who reported race, 219 were African American and 171 were White). MEASUREMENTS Extension Educators who work for the Cooperative Extension Service (a formalized educational outreach system associated with some U.S. universities) read aloud a 27-item instrument designed to assess risk factors for malnutrition. Response frequencies were tabulated and chi-square tests were performed using SAS 9.3. RESULTS More African Americans reported having a chronic illness or condition (81.2 vs. 68.3%; p=0.003), eating alone (66.2 vs. 53.6%; p=0.012), having a refrigerator that sometimes did not keep food cold (31.8 vs. 8.4%; p<0.0001), and sometimes not having enough money to buy food (38.9 vs. 18.5%; p<0.0001) compared to White older adults. CONCLUSION Rural older adults who attend congregate nutrition sites, especially African Americans, could be at risk for malnutrition due to health status and food preparation-related factors. Evidence-based, tailored programs are needed to minimize malnutrition among limited-resource older adults living in rural areas in the U.S.

Abstract
AbstractOne of the major challenges in developing appropriate vascular substitutes is to produce a graft that adapts to the biological and mechanical conditions at the application or implantation site. One approach is the use of tissue engineered electrospun grafts pre-seeded with autologous cells. However, bending stresses during in vivo applications could lead to kinking of the graft which may result in life-threatening stenosis. The aim of this study was to develop an electrospun vascular graft consisting of biodegradable polymers which can reduce or prevent kinking, due to their higher flexibility. In order to improve the bendability of the grafts, various electrospinning collectors were designed using six different patterns. Subsequently, the grafts were examined for scaffold morphology, mechanical strength and bendability. Scaffolds spun on a collector structured with a v-shaped thread (flank angle of 120°) showed a homogenous and reproducible fiber deposition as compared to the unstructured reference sample. The results of the tensile tests were comparable to the unstructured reference sample, supporting the first observation. Studies on bendability were performed using a custom made flow-bending test setup. It was shown that the flow through the v-shaped grafts was reduced to less than 45 % of the reference value even after bending the graft to an angle of 140°. In contrast, the flow through an unstructured graft was reduced to more than 50 % after bending to an angle of 55°. The presented data demonstrate the need for optimizing the bendability of the commonly used electrospun vascular grafts. Using of macroscopic v-shaped collectors is a promising solution to overcome the issue of graft kinking.

Abstract
AbstractElectrospinning is a versatile method of producing micro- and nanofibers deposited in mats used as scaffolds for tissue engineering. Depending on the application, single or coaxial electrospinning can be used. Coaxial electrospinning enables the use of a broad spectrum of materials, the fabrication of hollow or core/shell fibers and an automatisation of the entire electrospinning process. In this regard, the design of coaxial nozzles plays a major role in a standardized as well as tailor-made scaffold fabrication. For this purpose an optimised coaxial nozzle has been designed and fabricated. Furthermore, tests have been carried out to validate the new nozzle design. With the use of the costum-made nozzle polymer concentration could be varied in a gradual manner. The variation in polymer concentration lead to fiber diameters between 0.75 to 3.25 μm. In addition, an increase in rotating velocity lead to an increase in fiber alignment as well as a slight decrease in fiber diameter. The demonstrated modifications of coaxial electrospinning proved to be a powerful tool for in-process adjustments of scaffold fabrication.

Abstract
BACKGROUND The ozone challenge model can be used to assess the efficacy of anti-inflammatory compounds in early phases of clinical drug development. PUR118, a calcium salt based formulation engineered in the iSPERSE(TM) dry powder delivery technology, is a novel anti-inflammatory drug for COPD. Here we evaluated the efficacy and safety of three doses of PUR118 in attenuating ozone-induced airway inflammation in healthy volunteers. METHODS In a single-blind, phase 1B proof of concept study, 24 subjects were enrolled to sequentially receive three doses of PUR118 (5.5 mg, n = 18; 11.0 mg, n = 18; 2.8 mg, n = 16). Each dose was inhaled 3 times (1, 13, 25 h, preceded by 2 puffs salbutamol) before the ozone exposure (250 ppb, 3 h intermittent exercise). Sputum was induced 3 h after the end of exposure. RESULTS Sputum neutrophils, sputum CD14+ cells, as well as concentrations of IL1B, IL6, IL8, MMP9, and TNFA in sputum supernatant significantly increased after ozone exposure (n = 24). The percentage of sputum neutrophils (n = 12 who completed all treatments) did not change following treatment with different doses of PUR118. The high dose treatment group (n = 16) showed a decrease in the percentage and number of sputum macrophages (p ≤ 0.05) as well as a decrease in blood neutrophils (p = 0.04), and an increase in blood CD14 + cells (p = 0.04) compared to baseline. All dosages of PUR118 were safe and well tolerated. CONCLUSION Ozone challenge resulted in the expected and significant increase of sputum inflammatory parameters. Treatment with multiple rising doses of PUR118 was safe and three applications within 25 h prior to the ozone challenge had small effects on ozone-induced airway inflammation.

Abstract
A synthetic peptide (sPIF) analogous to the mammalian embryo-derived PreImplantation Factor (PIF) enables neuroprotection in rodent models of experimental autoimmune encephalomyelitis and perinatal brain injury. The protective effects have been attributed, in part, to sPIF's ability to inhibit the biogenesis of microRNA let-7, which is released from injured cells during central nervous system (CNS) damage and induces neuronal death. Here, we uncover another novel mechanism of sPIF-mediated neuroprotection. Using a clinically relevant rat newborn brain injury model, we demonstrate that sPIF, when subcutaneously administrated, is able to reduce cell death, reverse neuronal loss and restore proper cortical architecture. We show, both in vivo and in vitro, that sPIF activates cyclic AMP dependent protein kinase (PKA) and calcium-dependent protein kinase (PKC) signaling, leading to increased phosphorylation of major neuroprotective substrates GAP-43, BAD and CREB. Phosphorylated CREB in turn facilitates expression of Gap43, Bdnf and Bcl2 known to have important roles in regulating neuronal growth, survival and remodeling. As is the case in sPIF-mediated let-7 repression, we provide evidence that sPIF-mediated PKA/PKC activation is dependent on TLR4 expression. Thus, we propose that sPIF imparts neuroprotection via multiple mechanisms at multiple levels downstream of TLR4. Given the recent FDA fast-track approval of sPIF for clinical trials, its potential clinical application for treating other CNS diseases can be envisioned.

Abstract
This study analyses the influence of dynamic hydrostatic pressure on chondrogenesis of human meniscus-derived fibrochondrocytes and explores the differences in chondrogenic differentiation under loading conditions between cells derived from the avascular inner zone and vascularized outer region of the meniscus. Aggregates of human fibrochondrocytes with cell origin from the inner region or with cell origin from the outer region were generated. From the two groups of either cell origin, aggregates were treated with dynamic hydrostatic pressure (1Hz for 4h; 0.55-5.03MPa, cyclic sinusoidal) from day 1 to day 7. The other aggregates served as unloaded controls. At day 0, 7, 14 and 21 aggregates were harvested for evaluation including histology, immunostaining and ELISA analysis for glycosaminoglycan (GAG) and collagen II. Loaded aggregates were found to be macroscopically larger and revealed immunohistochemically enhanced chondrogenesis compared to the corresponding controls. Loaded or non-loaded meniscal cells from the outer zone showed a higher potential and earlier onset of chondrogenesis compared to the cells from the inner part of the meniscus. This study suggests that intrinsic factors like cell properties in the different areas of the meniscus and their reaction on mechanical load might play important roles in designing Tissue Engineering strategies for meniscal repair in vivo.

Abstract
OBJECTIVES To address the diagnostic value of circulating microRNAs (miRNAs) in patients presenting with acute chest pain. DESIGN In a prospective, international, multicentre study, six miRNAs (miR-133a, miR-208b, miR-223, miR-320a, miR-451 and miR-499) were simultaneously measured in a blinded fashion in 1155 unselected patients presenting with acute chest pain to the emergency department. The final diagnosis was adjudicated by two independent cardiologists. The clinical follow-up period was 2 years. RESULTS Acute myocardial infarction (AMI) was the adjudicated final diagnosis in 224 patients (19%). Levels of miR-208b, miR-499 and miR-320a were significantly higher in patients with AMI compared to those with other final diagnoses. MiR-208b provided the highest diagnostic accuracy for AMI (area under the receiver operating characteristic curve 0.76, 95% confidence interval 0.72-0.80). This diagnostic value was lower than that of the fourth-generation cardiac troponin T (cTnT; 0.84) or the high-sensitivity cTnT (hs-cTnT; 0.94; both P < 0.001 for comparison). None of the six miRNAs provided added diagnostic value when combined with cTnT or hs-cTnT (ns for the comparison of combinations vs. cTnT or hs-cTnT alone). During follow-up, 102 (9%) patients died. Levels of MiR-208b were higher in patients who died within 30 days, but the prognostic accuracy was low to moderate. None of the miRNAs predicted long-term mortality. CONCLUSION The miRNAs investigated in this study do not seem to provide incremental diagnostic or prognostic value in patients presenting with suspected AMI.
