Background: Seven per cent of general waste and 20% of healthcare risk waste produced in acute hospitals in Ireland comes from operating theatres. Surgical wrap comprises 11% of operating theatre waste. Aims: The primary aim of this study was to pilot the implementation of a recycling initiative for surgical instrument set wrap in an operating theatre in Ireland. Secondary aims included quantification of the surgical wrap diverted from general waste to recycling streams over a 5-week period and estimation of the annual carbon emissions associated with gynaecology surgical wrap use in Cork. Methods: The amount of polypropylene surgical wrap generated by a single gynaecology theatre at Cork University Maternity Hospital was prospectively quantified from 24/1/22 to 1/3/22. At the end of the study period, individual sheets of polypropylene wrap were counted and dimensions were measured to calculate the total surface area of surgical wrap saved for recycling. Results: A total of 66 surgeries were performed over the 5-week study period. Two hundred twenty-one individual sheets of surgical wrap were collected, equating to 282.1 m2 of polypropylene wrap. An estimated 11,564 m2 of surgical wrap could be recycled annually from the gynaecology theatre service in Cork with an associated annual carbon emissions equivalent of at least 2.2 tonnes of CO2. Conclusion: Diversion of surgical wrap from general waste and clinical waste streams to the recycling stream is achievable in every operating theatre. Small changes to operating theatre waste disposal practices have the potential to yield significant reductions to theatre waste outputs and to hospital carbon emissions. [ABSTRACT FROM AUTHOR]

In this paper we provide an introduction to a set of tools for syntactic analysis based on graph theory, and apply them to the study of some properties of English accusativus cum infinitivo constructions, more commonly known as raising to object or exceptional case marking structures. We focus on puzzling extraction asymmetries between base-generated objects and 'raised' objects and on the interaction between raising to object and Right Wrap. We argue that a lexicalised derivational grammar with grammatical functions as primitives delivers empirically adequate analyses. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Our objective was determining the optimal combinations of cerebrospinal fluid (CSF) biomarkers for predicting disease progression in Alzheimer's disease (AD) and other neurodegenerative diseases. METHODS: We included 1,983 participants from three different cohorts with longitudinal cognitive and clinical data, and baseline CSF levels of Aβ42, Aβ40, phosphorylated tau at threonine‐181 (p‐tau), neurofilament light (NfL), neurogranin, α‐synuclein, soluble triggering receptor expressed on myeloid cells 2 (sTREM2), glial fibrillary acidic protein (GFAP), YKL‐40, S100b, and interleukin 6 (IL‐6) (Elecsys NeuroToolKit). RESULTS: Change of modified Preclinical Alzheimer's Cognitive Composite (mPACC) in cognitively unimpaired (CU) was best predicted by p‐tau/Aβ42 alone (R2 ≥ 0.31) or together with NfL (R2 = 0.25), while p‐tau/Aβ42 (R2 ≥ 0.19) was sufficient to accurately predict change of the Mini‐Mental State Examination (MMSE) in mild cognitive impairment (MCI) patients. P‐tau/Aβ42 (AUC ≥ 0.87) and p‐tau/Aβ42 together with NfL (AUC ≥ 0.75) were the best predictors of conversion to AD and all‐cause dementia, respectively. DISCUSSION: P‐tau/Aβ42 is sufficient for predicting progression in AD, with very high accuracy. Adding NfL improves the prediction of all‐cause dementia conversion and cognitive decline.

Although the rate of infection after the reconstruction of a ruptured anterior cruciate ligament (ACL) is low, prophylactic incubation of the graft with vancomycin (Vanco-wrap or vancomycin soaking) is routinely performed. A cytotoxic effect of vancomycin is reported for several cell types, and the prophylactic treatment might prevent infection but harm the tissue and cells. Aim: A comprehensive study was performed to investigate the effect of vancomycin on tendon tissue and isolated tenocytes using cell viability, molecular and mechanical analysis. Material and methods: Rat tendons or isolated tenocytes were incubated in increasing concentrations of vancomycin (0–10 mg/mL) for different times, and cell viability, gene expression, histology and Young's modulus were analyzed. Results: The clinically used concentration of vancomycin (5 mg/mL for 20 min) had no negative effect on cell viability in the tendons or the isolated tenocytes, while incubation with the toxic control significantly reduced cell viability. Increasing the concentration and prolonging the incubation time had no negative effect on the cells. The expression of Col1a1, Col3a1 and the tenocyte markers mohawk, scleraxis and tenomodulin was not affected by the various vancomycin concentrations. The structural integrity as measured through histological and mechanical testing was not compromised. Conclusion: The results proved the safe application of the Vanco-wrap on tendon tissue. Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Antimicrobial coatings have a finite lifetime because of wear, depletion of the active ingredient, or surface contamination that produces a barrier between the pathogen and the active ingredient. The limited lifetime means that facile replacement is important. Here, we describe a generic method for rapidly applying and reapplying antimicrobial coatings to common-touch surfaces. The method is to deposit an antimicrobial coating on a generic adhesive film (wrap), and then to attach that modified wrap to the common-touch surface. In this scenario, the adhesion of the wrap and antimicrobial efficacy are separated and can be optimized independently. We demonstrate the fabrication of two antimicrobial wraps, both using cuprous oxide (Cu2O) as the active ingredient. The first uses polyurethane (PU) as the polymeric binder and the second uses polydopamine (PDA). Our antimicrobial PU/Cu2O and PDA/Cu2O wraps, respectively, kill >99.98% and >99.82% of the human pathogen, P. aeruginosa, in only 10 min, and each of them kill >99.99% of the bacterium in 20 min. These antimicrobial wraps can be removed and replaced on the same object in <1 min with no tools. Wraps are already frequently used by consumers to coat drawers or cars for aesthetic or protective purposes. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical application value of integrated wrapping and reinforcing technique of ligamentum teres hepatis and falciform ligament in pancreaticoduodenectomy (PD) of soft pancreas. Methods: Clinical data of patients with soft pancreas undergoing opern PD or pylorus-preserving pancreaticoduodenectomy (PPPD) were retrospectively analyzed in Harbin Medical University Cancer Hospital from January 2016 to December 2021. According to whether the integrated wrapping and reinforcing technique of ligamentum teres hepatis and falciform ligament was applied, the patients were divided into two groups: non-wrapping or rein- forcing group (2016.1-2018.12, 246 cases), wrapping and reinforcing group (2019.1-2021.12, 244 cases). The basic preoperative characteristics, intraoperative data, postoperative data, treatment measures and outcomes of patients with post-pancreatectomy hemorrhage. (PPH) were compared between the two groups. Results: In preoperative basic clinical data, there were no significant differences in age, gender, preoperative hypertension and diabetes history, American society of anesthesiologists (ASA) score, preoperative alanine amino- transferase, serum albumin and total bilirubin, preoperative biliary drainage, tumor location and tumor nature between the two groups (P>0.05). In intraoperative data, there were no significant differences in operative time, intraoperative blood loss, intraoperative blood transfusion, resection type, PV or SMV resection and reconstruction, and main pancreatic duct diameter between the two groups (P>0.05). In postoperative data, there were significant differences in the incidence of overall postoperative complications, clinically related postoperative pancreatic fistula (CR-POPF) and intra-abdominal infection, rate of percutaneous catheter drainage, incidence of late extraluminal post-pancreatectomy hemorrhage (PPH) and grade C late extraluminal PPH, and rates of PPH-related reoperation and total reoperation, and postoperative hospital stay between the two groups (P<0.05); There were no significant differences in postoperative biliary fistula, delayed gastric empty, early PPH, late intraluminal PPH, grade A and grade B late extraluminal PPH, and perioperative mortality between the two groups (P>0.05). In terms of treatment measures and outcomes of PPH patients, there was significant difference in the rate of the invasive treatment between the two groups (P<0.05); There were no significant differences in the different invasive treatment options and rate of PPH case-fatality between the two groups (P>0.05). Conclusion: The technique of integrated wrapping and reinforcing of ligamentum teres hepatis and falciform ligament can reduce the incidence of overall postoperative complications, CR-POPF, late extraluminal PPH and grade C late extraluminal PPH after PD in patients with soft pancreas, and it can also simultaneously reduce the incidence of intra-abdominal infection, the rates of percutaneous catheter drainage and reoperation, and shorten postoperative hospital stay.

In this article, a new technology of surface wrapping and strengthening of expandable polystyrene (EPS) beads is proposed. Three wrapping materials including magnesium phosphate cement (MPC), ultra-high performance concrete (UHPC), and water-borne polyurethane (WPU) were evaluated. Four groups of uniaxial compression tests of EPS concrete specimens were conducted: the failure process and the characteristics of the specimens were analyzed; and the complete stress–strain equation is proposed based on these analyses. The research shows that the EPS beads were strengthened by wrapping, and the axial compressive strength of concrete is increased by 50–75%; the concrete with EPS beads wrapped by MPC and WPU has obvious brittleness; the concrete with EPS beads wrapped by UHPC has axial compressive strength close to that of EPS concrete wrapped with MPC and WPU but has a larger ductility coefficient (150%), a larger toughness coefficient (50–90% larger), a higher energy dissipation coefficient (40% larger), and larger residual stress. The proposed stress–strain model is in good agreement with the experimental results, which can accurately describe the stress and deformation characteristics of EPS concrete under uniaxial compression and has good applicability. The discovery of this study provides background knowledge for the structural analysis and design of this kind of concrete; it provides a basis for selecting EPS concrete as structural materials.

Cryogenic tanks are still considered the most efficient method of storing fluids. This is due to its resistance to much damage caused by corrosion induced by low temperature and internal pressure. In this study, the finite element method is used to analyze the repair performance by a composite wrap in a corroded tank. A parametric analysis was carried out in order to highlight the effects of low temperature and pressure on the thermo-mechanical behavior of the corroded structure and to predict the evolution of stresses in the vicinity of corrosion. An approach to this problem based on the notion of material strength was necessary since it was essential to take both the size of the pre-existing defect and the amount of mechanical stresses. The results obtained show the effect of thermal and mechanical loading to examine their impact on the strength of the structure on the one hand, and on the other hand, the influence of the composite wrap repair in the different corrosion lengths (Path 1, 2, 3) on the reinforcement of the tank. Finally, repairing damage (corrosion) using FRP composites increases the durability of cryogenic tanks, which increases their efficiency their performance and increases their life, although the rate of improvement depends largely on operating conditions, such as pressure and temperature.

Resolvin D1 (RvD1) belongs to a family of endogenously derived proresolving lipid mediators that have been shown to attenuate inflammation, activate proresolution signaling, and promote homeostasis and recovery from tissue injury. In this study we present a poly(lactic-co-glycolic acid) (PLGA) based thin-film device composed of layers of varying ratios of lactic and glycolic acid that elutes RvD1 unidirectionally to target tissues. The device demonstrated sustained release in vitro for 56 days with an initial burst of release over 14 days. The asymmetric design of the device released 98% of RvD1 through the layer with the lowest molar ratio of lactic acid to glycolic acid, and the remainder through the opposite side. We validated structural integrity of RvD1 released from the device by mass spectrometry and investigated its bioactivity on human vascular endothelial (EC) and smooth muscle cells (VSMC). RvD1 released from the device attenuated VSMC migration, proliferation, and TNF-α induced NF-κB activation, without evidence of cytotoxicity. Delivery of RvD1 to blood vessels was demonstrated ex vivo in a flow chamber system using perfused rabbit aortas and in vivo in a rat carotid artery model, with the devices applied as an adventitial wrap. Our results demonstrate a novel approach for sustained, local delivery of Resolvin D1 to vascular tissue at therapeutically relevant levels. © 2016 Wiley Periodicals, Inc.

Synchrony plays a major role in the interconnection process between local electric power generation systems and the electrical grid. Grid phase disturbances prevent the generation system from maintaining synchrony. Therefore, an efficient phase tracking method is necessary in order to detect phase jumps and abrupt changes in amplitude. In this paper, we propose a software-designed method to strengthen phase tracking based on the wrap process of a second-level Phase Locked Loop (PLL). The term ‘wrap’ means establishing the phase values of the reference signal in intervals of π to match it with the values obtained from the PLL output (sync pulse). To quantify phase error, a mathematical transformation of the time domain to the frequency domain is implemented. The validity of the proposed wrap function is verified using electrical disturbances.

In this study the finite element method is used to analyze the performances of bonded composite wrap repair of cracked steel pipelines. Parametric analysis was performed in order to highlight the effects of the geometrical properties on the repair efficiency. The experimental design method is used to explore the effects of wrap dimensions (length, angle and thickness) in order to optimize the repair process. We showed in using the MOODE.5 software the most dominant geometrical parameters on stress intensity factor at the crack front which to determine the most important parameters on the repair efficiency. This optimization can help the composite wrap designers to improve the repair performance and rehabilitation

The key approach to manage and prevent potential hazards arising from specific contaminants in water networks is to consider water as the main product delivered. This new concept, addressed as water-reuse risk assessment program (WRAP), has been further developed from hazard analysis of critical control points (HACCP) to illustrate the potential hazards which are the roots of hindering intra-facility water reuse strategies. For industrial sectors applying water reclamation and reuse schemes, it is paramount that the reclaimed water quality stays within the desired quality. The objective of WRAP is to establish a new methodology and knowledge, which will contribute to the sustainable development of industrial water management, and demonstrate its capabilities in identifying and addressing any potential hazards in the selected schemes adoption by the industries. A ‘what-if’ scenario was simulated using a refinery as a case study to show strategies on how to benefit reclaimed or reuse water based on reliable, applied and scientific research within the process integration area. In conclusion, the WRAP model will facilitate operators, consultants and decision makers to reuse water on a fit-for-use basis whilst avoiding contaminant accumulation in the overall system and production of sub-quality products from inadequate processes after several reuses.

NIMH requires intervention research to utilize an experimental therapeutic approach, identifying mediators to examine causal mechanisms of change. The authors propose utilizing self-determination theory (SDT) to guide research design for self-management interventions, using Wellness Recovery Action Plan (WRAP) as an exemplar. To delineate the theory's relevance to self-management interventions and recovery outcomes, the authors describe the main constructs of SDT and demonstrate its applicability to WRAP and recovery. Suggestions for research design and measurement strategies are provided. [ABSTRACT FROM AUTHOR]

Prehensile and gripping organs are recurring structures in different organisms that enhance friction by the reinforcement and redirection of normal forces. The relationship between organ structure and biomechanical performance is poorly understood, despite a broad relevance for microhabitat choice, movement ecology and biomimetics. Here, we present the first study of the biomechanics of prehensile feet in long-legged harvestmen. These arachnids exhibit the strongest sub-division of legs among arthropods, permitting extreme hyperflexion (i.e. curling up the foot tip). We found that despite the lack of adhesive foot pads, these moderately sized arthropods are able to scale vertical smooth surfaces, if the surface is curved. Comparison of three species of harvestmen differing in leg morphology shows that traction reinforcement by foot wrapping depends on the degree of leg sub-division, not leg length. Differences are explained by adaptation to different microhabitats on trees. The exponential increase of foot section length from distal to proximal introduces a gradient of flexibility that permits adaptation to a wide range of surface curvature while maintaining integrity at strong flexion. A pulley system of the claw depressor tendon ensures the controlled flexion of the high number of adesmatic joints in the harvestman foot. These results contribute to the general understanding of foot function in arthropods and showcase an interesting model for the biomimetic engineering of novel transportation systems and surgical probes.
