Single-blind randomized clinical trial to evaluate clinical and radiological outcomes after one year of immediate versus delayed implant placement su…
2013
Purpose: To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. Material and Methods: The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-extraction and in Group B six months after extraction. The following control time-points were established: one week, six months and twelve months after loading. Measurements were taken of peri-implant crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified …
Tibial Nerve Block: Supramalleolar or Retromalleolar Approach? A Randomized Trial in 110 Participants.
2020
Of the five nerves that innervate the foot, the one in which anesthetic blocking presents the greatest difficulty is the tibial nerve. The aim of this clinical trial was to establish a protocol for two tibial nerve block anesthetic techniques to later compare the anesthetic efficiency of retromalleolar blocking and supramalleolar blocking in order to ascertain whether the supramalleolar approach achieved a higher effective blocking rate. A total of 110 tibial nerve blocks were performed. Location of the injection site was based on a prior ultrasound assessment of the tibial nerve. The block administered was 3 mL of 2% mepivacaine. The two anesthetic techniques under study provided very simi…
Ultrasound-Guided Infraclavicular Axillary Vein Versus Internal Jugular Vein Cannulation in Critically Ill Mechanically Ventilated Patients: A Random…
2022
OBJECTIVES: This clinical trial aimed to compare the ultrasound-guided in-plane infraclavicular cannulation of the axillary vein (AXV) and the ultrasound-guided out-of-plane cannulation of the internal jugular vein (IJV). DESIGN: A prospective, single-blinded, open label, parallel-group, randomized trial. SETTING: Two university-affiliated ICUs in Poland (Opole and Lublin). PATIENTS: Mechanically ventilated intensive care patients with clinical indications for central venous line placement. INTERVENTIONS: Patients were randomly assigned into two groups: the IJV group (n = 304) and AXV group (n = 306). The primary outcome was to compare the IJV group and AXV group through the venipuncture an…
Success Factors in Funding Acquisition for Research Projects through Competitive Calls: A study of R&D Public Centres
2017
Durante los últimos años, la capacidad de generación de recursos financieros derivados de la obtención de fondos competitivos ha sido una preocupación creciente para las organizaciones públicas de investigación y desarrollo (I+D), al garantizar su supervivencia y el futuro de los actuales sistemas de bienestar público implementados en la mayoría de los países europeos (Bazeley, 1998; Lee y Om, 1996; Muñoz, 2007; Santamaría, Brage-Gil, y Modrego, 2010). La literatura actual describe ampliamente las características y el impacto de los principales programas de financiación competitiva internacional (Galsworthy y McKee, 2013; Grimpe, 2012; Laudel, 2005, 2006), la magnitud de la eficacia de los …
Does periodization work? Athletes perform better in major events than in minor competitions
2022
Previous studies on periodization have led to the view that most athletes fail to peak at major events. These conclusions might be based on definitions of “peak performance” that are too narrow. In this study, a track and field athlete was defined as succeeding in a competition if their outcome was within the acceptable range from the best result of the season. The data are from seven championship finals and semifinals together with 42 Diamond League competitions from the 2010s, altogether 7,087 individual results. All field events and running events up to 400 m were included. The majority of athletes succeeded in major events (67.0% in sprint and 57.5% in field events). Overall, championsh…
Multi-Skill Call Center as a Grading from “Old” Telephony
2009
We explore parallels between the older telephony switches and the multi-skill call centers. The numerical results have shown that a call center with equally distributed skills is preferable compared to traditional grading-type design. The annex contains a short version of mathematical proof on limited availability schemes design for small call flow intensity *** and for large *** . The proof explores one excellent V. Benes' paper (from Bell Labs). On its own merit, the annex could initiate new mathematical research in call center area, more by now the powerful software for numerical analysis is available. Main conclusion is the following: numerical analysis of simple multi-skill call center…
Reforming the Teaching and Learning of Foundational Mathematics Courses: An Investigation into the Status Quo of Teaching, Feedback Delivery, and Ass…
2022
Several universities are witnessing an increase in students’ enrolment in mathematics-intensive programmes over the last decades. This increase has come with the price of high failure rates in foundational mathematics courses, which poses challenges to mathematics teaching and learning in higher education. It is therefore inevitable, for some universities, to transform the teaching and learning of mathematics to more student-centred approaches that engage the students mathematically and enhance their success rates. We approach this transformative effort by investigating students’ perception of teaching, feedback, and assessment as a first step in reforming the teaching of a firs…
