The impact of quality management systems on construction performance in the North West of England

As the total construction output in the North West of England (NWE) is forecast to rise by an average of 2.5% over the next five years. It is imperative for organizations in the region to improve their overall construction performance, particularly if they are to hit the targets presented by UK Government in the construction 2025 report. Despite the known benefits of quality management systems (QMS) its implementation in relation to construction performance is very limited, particularly in the UK. Therefore, the purpose of this paper is to examine whether QMS can affect construction performance in the NWE. A pragmatic mixed method approach of sequential explanatory strategy was adopted to conduct this research. This initially involved a quantitative approach of questionnaire surveys to gain opinions and views of a representative sample of industry professionals based in the NWE. The quantitative results were analyzed to discover relationships in the data and further formulate the questions for the qualitative interviews. Three interviews with leading industry professionals were then conducted and the data was analyzed using a thematic approach. The themes identified in the interviews were then cross-referenced with the data discovered in the questionnaire survey and literature review. The findings provide a clear indication that the implementation of a QMS has a positive effect on construction performance in the NWE. Immediate improvements in efficiency of a construction organization when implementing a QMS were discovered, including greater managerial control and the recording and reduction in defects. Long term effects of changing company attitude by setting out company requirements and responsibilities through highlighting the significance of quality, and furthermore encouraging a culture of co-operation and teamwork, were also proven to increase construction performance as time progresses. To further enhance this research the focus could be on the whole of the UK. However, a greater amount of time would be required to gain the required representative sample. Furthermore, although the questionnaire survey was distributed equally within the selected sample, a greater number of respondents working for contractors responded. Therefore, the respondents of the questionnaire survey were not equal in terms of organization (client, contractor, sub-contractor, project manager). According to the best knowledge of the authors and through searching many sources, there are no specific studies examining QMS and their effect on construction performance in the UK and particularly in the NWE. Therefore, it is believed the study is the first of its kind. The study discovered many findings that can be considered as a contribution to practice and theory. Moreover, it can be considered as a fundamental base for future studies in this research area. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group

Building an immune-mediated coagulopathy consensus: early recognition and evaluation to enhance post-surgical patient safety

Topical hemostats, fibrin sealants, and surgical adhesives are regularly used in a variety of surgical procedures involving multiple disciplines. Generally, these adjuncts to surgical hemostasis are valuable means for improving wound visualization, reducing blood loss or adding tissue adherence; however, some of these agents are responsible for under-recognized adverse reactions and outcomes. Bovine thrombin, for example, is a topical hemostat with a long history of clinical application that is widely used alone or in combination with other hemostatic agents. Hematologists and coagulation experts are aware that these agents can lead to development of an immune-mediated coagulopathy (IMC). A paucity of data on the incidence of IMC contributes to under-recognition and leaves many surgeons unaware that this clinical entity, originating from normal immune responses to foreign antigen exposure, requires enhanced post-operative vigilance and judicious clinical judgment to achieve best outcomes

Impact of inflammation, gene variants, and cigarette smoking on coronary artery disease risk

Background: The role of inflammation in coronary artery disease (CAD) pathogenesis is well recognized. Moreover, smoking inhalation increases the activity of inflammatory mediators through an increase in leukotriene synthesis essential in atherosclerosis pathogenesis.Aim: The aim of this study is to investigate the effect of “selected” genetic variants within the leukotriene (LT) pathway and other variants on the development of CAD.Methods: CAD was detected by cardiac catheterization. Logistic regression was performed to investigate the association of smoking and selected susceptibility variants in the LT pathway including ALOX5AP, LTA4H, LTC4S, PON1, and LTA as well as CYP1A1 on CAD risk while controlling for age, gender, BMI, family history, diabetes, hyperlipidemia, and hypertension.Results: rs4769874 (ALOX5AP), rs854560 (PON1), and rs4646903 (CYP1A1 MspI polymorphism) are significantly associated with an increased risk of CAD with respective odds ratios of 1.53703, 1.67710, and 1.35520; the genetic variant rs9579646 (ALOX5AP) is significantly associated with a decreased risk of CAD (OR 0.76163). Moreover, a significant smoking-gene interaction is determined with CYP1A1 MspI polymorphism rs4646903 and is associated with a decreased risk of CAD in current smokers (OR 0.52137).Conclusion: This study provides further evidence that genetic variation of the LT pathway, PON1, and CYP1A1 can modulate the atherogenic processes and eventually increase the risk of CAD in our study population. Moreover, it also shows the effect of smoking-gene interaction on CAD risk, where the CYP1A1 MspI polymorphism revealed a decreased risk in current smokers
