Inhaled amikacin versus placebo to prevent ventilator-associated pneumonia: the AMIKINHAL double-blind multicentre randomised controlled trial protoc…
2021
IntroductionPre-emptive inhaled antibiotics may be effective to reduce the occurrence of ventilator-associated pneumonia among critically ill patients. Meta-analysis of small sample size trials showed a favourable signal. Inhaled antibiotics are associated with a reduced emergence of antibiotic resistant bacteria. The aim of this trial is to evaluate the benefit of a 3-day course of inhaled antibiotics among patients undergoing invasive mechanical ventilation for more than 3 days on the occurrence of ventilator-associated pneumonia.Methods and analysisAcademic, investigator-initiated, parallel two group arms, double-blind, multicentre superiority randomised controlled trial. Patients invasi…
The Impact of the COVID-19 Pandemic on ICU Healthcare Professionals: A Mixed Methods Study
2021
The large numbers of patients admitted to intensive care units due to COVID-19 has had a major impact on healthcare professionals. The incidence of mental health disorders among these professionals has increased considerably and their professional quality of life has suffered during the pandemic. This study aims to explore the impact of the provision of COVID-19 patient care on ICU healthcare professionals. A mixed methods study with an exploratory concurrent design was conducted between June and November 2020 in the Balearic Islands, Spain. Data were collected using a self-report online survey (n = 122) based on three validated questionnaires, and individual semi-structured in-depth online…
Odontogenic fibroma — a case report
2014
Abstract IThe present study outlines the case of a 30-year-old patient with central odontogenic fibroma. The tumour developed in the alveolar process of the maxilla in the area of 13–15. The study describes the clinical symptoms, the radiological image, treatment method and histopathological image of the tumour. The study also presents a one-year period of post-surgical observation.
Teaching the placement of posterior resin-based composite restorations in Spanish dental schools
2012
Objectives: In an area of esthetic dentistry such as posterior composites, in which new materials and techniques are being devolved continuously, it is important to confirm that dental students have a clear understanding of the basic principles of clinical application of this knowledge. Considering that the preparation of dental graduates in Spain may be of interest to competent dental authorities and employers with whom they can work worldwide, this study investigated the teaching of posterior composite restorations in Spanish dental schools. Study design: In late 2009/ early 2010, a questionnaire seeking information on the teaching of posterior composites was emailed to the professor resp…
Is COVID‐19 infection more severe in kidney transplant recipients?
2021
International audience; There are no studies which have compared the risk of severe Covid-19 and related mortality between transplant recipients and non-transplant patients. We enrolled two groups of patients hospitalized for Covid-19, i.e., kidney transplant recipients from the French Registry of Solid Organ Transplant (n=306) and a single-center cohort of non-transplant patients (n=795). An analysis was performed among subgroups matched for age and risk factors for severe Covid-19 or mortality. Severe Covid-19 was defined as admission (or transfer) to an intensive care unit, need for mechanical ventilation, or death.Transplant recipients were younger and had more comorbidities compared to…
Mid- to Long-Term Outcomes of Cervical Disc Arthroplasty versus Anterior Cervical Discectomy and Fusion for Treatment of Symptomatic Cervical Disc Di…
2015
Purpose This study aimed to investigate the mid- to long-term outcomes of cervical disc arthroplasty (CDA) versus anterior cervical discectomy and fusion (ACDF) for the treatment of 1-level or 2-level symptomatic cervical disc disease. Methods Medline, Embase, and the Cochrane Central Register of Controlled Trials databases were searched to identify relevant randomized controlled trials that reported mid- to long-term outcomes (at least 48 months) of CDA versus ACDF. All data were analyzed by Review Manager 5.3 software. The relative risk (RR) and 95% confidence intervals (CIs) were calculated for dichotomous variables. The weighted mean difference (WMD) and 95%CIs were calculated for conti…
Memoria y paz. Perspectivas decoloniales en la construcción de la memoria colectiva
2018
The objective of this article is to analyse methodological principles in studies that link the construction of memory with decolonisation. Based on two decolonial approaches, the colonial and epistemic difference, a comparative study of collaborative research on memory in Latin America was carried out. This analysis contributes to the conceptual-critical reflection of the construction of memory in a decolonial framing and presents through innovative methodologies meaning shifts of official narratives. In conclusion, it proposes the integration of the territorial dimension and the subjectivity of the participants and their communities as a way of transformation towards peaceful societies
Salesperson adoption and usage of mobile sales configuration tools
2018
PurposeThe purpose of this paper is to examine salespersons’ adoption and usage of mobile sales configuration tools (MSCT) and to identify areas for further development in this realm. Another objective is to offer a conceptualization of MSCT adoption.Design/methodology/approachFor this purpose, a qualitative case study approach was selected as the research method to better understand acceptance of a mobile configuration tool used by business-to-business (B2B) salespersons. Primary data were collected through semi-structured interviews, which included a series of open-ended questions to gain more detailed and contextual data.FindingsThe results obtained from the interviews indicated several …
DESMILS : a decision support approach for multi-item lot sizing using interactive multiobjective optimization
2023
AbstractWe propose a decision support approach, called DESMILS, to solve multi-item lot sizing problems with a large number of items by using single-item multiobjective lot sizing models. This approach for making lot sizing decisions considers multiple conflicting objective functions and incorporates a decision maker’s preferences to find the most preferred Pareto optimal solutions. DESMILS applies clustering, and items in one cluster are treated utilizing preferences that the decision maker has provided for a representative item of the cluster. Thus, the decision maker provides preferences to solve the single-item lot sizing problem for few items only and not for every item. The lot sizes …
Evaluation of a lattice-Boltzmann method for mercury intrusion porosimetry simulations
2004
We have simulated intrusion of a non-wetting liquid into pores of varying shape and size. Simulations were based on the lattice-Boltzmann method and the Shan–Chen multiphase model. The liquid–solid contact angle for pores with circular cross-section was found to be equal to that for pores with square cross-section, and constant even for small pore sizes if the discretised shape of the circular cross-section was taken into account. For comparison, contact angle was also determined for a liquid column descending in a capillary tube, and the results were found to be consistent. Application of the method to mercury intrusion porosimetry is discussed.
