Background: Blood pressure variability (BPV) is a predictor of short- and long-term disability in patients with acute ischemic stroke (AIS). Its effect on more immediate functional outcomes has been seldom studied, and the results are inconsistent. We aimed to determine the role of BPV during the first 5 days of hospitalization in functional status at the time of discharge of patients with AIS.Methods: We enrolled 134 patients diagnosed with AIS and BPV using standard deviation and coefficient of variation (CV %). These were associated with the dichotomized modified Rankin Scale at discharge using logistic regression. Results: Patients with unfavorable outcomes were significantly older (P=0.014), had a lower body mass index (P=0.001), were less likely to present with dyslipidemia (P=0.001), had lower serum triglyceride levels (P=0.012), had a longer hospitalization period (P<0.001), and had a higher mean National Institutes of Health Stroke Scale score at admission (P<0.001). After adjusting for multiple confounders, the CV % of systolic blood pressure (SBP) in the first 120 hours after admission had a significant effect on functional disability at discharge. Conclusion: Variability in SBP in the first 5 days of hospitalization had a deleterious effect on the functional outcomes at discharge of patients with AIS. The role of diabolic blood pressure variability seems to be significant only in the first 24 hours of admission; however, further research is required.

Objectives This study aimed to compare the torsional and cyclic fatigue resistance of ProGlider (PG), WaveOne Gold Glider (WGG), and TruNatomy Glider (TNG). Materials and Methods A total of 15 instruments of each glide path system (n = 15) were used for each test. A custom-made device simulating an angle of 90° and a radius of 5 millimeters was used to assess cyclic fatigue resistance, with calculation of number of cycles to failure. Torsional fatigue resistance was assessed by maximum torque and angle of rotation. Fractured instruments were examined by scanning electron microscopy (SEM). Data were analyzed with Shapiro-Wilk and Kruskal-Wallis tests, and the significance level was set at 5%. Results The WGG group showed greater cyclic fatigue resistance than the PG and TNG groups (p < 0.05). In the torsional fatigue test, the TNG group showed a higher angle of rotation, followed by the PG and WGG groups (p < 0.05). The TNG group was superior to the PG group in torsional resistance (p < 0.05). SEM analysis revealed ductile morphology, typical of the 2 fracture modes: cyclic fatigue and torsional fatigue. Conclusions Reciprocating WGG instruments showed greater cyclic fatigue resistance, while TNG instruments were better in torsional fatigue resistance. The significance of these findings lies in the identification of the instruments’ clinical applicability to guide the choice of the most appropriate instrument and enable the clinician to provide a more predictable glide path preparation.
Outcomes of arthroscopic dorsal wrist ganglion excision: a 44-month retrospective comparative study
Amaro Pedro,Cardoso Afonso,Caldeira José,Falcão Pedro,Baptista Carolina 대한정형외과 스포츠의학회 2020 Arthroscopy and Orthopedic Sports Medicine Vol.7 No.2
Background: This study retrospectively compares the clinical outcomes of excision of dorsal cysts of the wrist by open and arthroscopic approaches, considering three variables: recurrence rates, residual pain, and the time required for patients to return to their work activities. Methods: All patients who submitted to open or arthroscopic surgical excision of wrist ganglions between January 2012 and December 2017 were evaluated with a mean follow-up period of 44 months. Preoperative and postoperative pains were evaluated using a visual analogue scale, and functional outcomes were evaluated using the Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire. Recurrences were confirmed by clinical examination, ultrasound, or magnetic resonance imaging. Results: Our study showed that there are no statistically significant differences between the two surgical techniques regarding the recurrence rate or residual pain. Conclusion: Patients who underwent arthroscopic surgery had a statistically significant early return to work.
Creative Milieus, Gatekeepers and Cultural Production : Evidence from a Survey to Portuguese Artists
Pedro Costa 한국문화경제학회 2008 문화경제연구 Vol.11 No.1
This paper aims to explore the relation between territorial agglomeration of cultural activities and the development of specific gatekeeping processes, which embed, support and foster creativity, and play a fundamental role in the industrial organization of these activities. In the sequence of a previous conceptual research about creativity and the relation between territorial agglometarion and the development of creative process in cultural production, a survey was developed and applied to cultural “creators” in Portuguese urban areas, in order to understand their perceptions about their creative processes, the economic organization of their activity and its institutional framework. Some of the results of this survey are analyzed and discussed, with the focus on the issues related to the symbolic and cultural intermediation. Some preliminary conclusions are drawn, having in mind the promotion of cultural-based sustainable urban creative dynamics.
The use of digital periapical radiographs to study the prevalence of alveolar domes
Pedro Augusto Oliveira Santos Xambre,Claudia Scigliano Valerio,Claudia Assunção e Alves Cardoso,Antônio Luís Neto Custódio,Flávio Ricardo Manzi 대한영상치의학회 2016 Imaging Science in Dentistry Vol.46 No.3
Purpose: In the present study, we coined the term ‘alveolar dome’ and aimed to demonstrate the prevalence of alveolar domes through digital periapical radiographs. Materials and Methods: This study examined 800 digital periapical radiographs in regard to the presence of alveolar domes. The periapical radiographs were acquired by a digital system using a photostimulable phosphor (PSP) plate. The χ2 test, with a significance level of 5%, was used to compare the prevalence of alveolar domes in the maxillary posterior teeth and, considering the same teeth, to verify the difference in the prevalence of dome-shaped phenomena between the roots. Results: The prevalence of alveolar domes present in the first pre-molars was statistically lower as compared to the other maxillary posterior teeth (p<0.05). No statistically significant difference was observed in the prevalence of alveolar domes between the maxillary first and second molars. Considering the maxillary first and second molars, it was observed that the palatal root presented a lower prevalence of alveolar domes when compared to the distobuccal and mesiobuccal roots (p<0.05). Conclusion: The present study coined the term ‘alveolar dome’, referring to the anatomical projection of the root into the floor of the maxillary sinus. The maxillary first and second molars presented a greater prevalence of alveolar domes, especially in the buccal roots, followed by the third molars and second pre-molars. Although the periapical radiograph is a two-dimensional method, it can provide dentists with the auxiliary information necessary to identify alveolar domes, thus improving diagnosis, planning, and treatment.
The role of e-commerce in the internationalization of Spanish luxury fashion multi-brand retailers
Pedro Mir-Bernal,Simone Guercini,Teresa Sádaba 한국마케팅과학회 2018 Journal of Global Fashion Marketing Vol.9 No.1
The aim of this paper is to analyze the role that e-commerce has to play in the internationalization of Spanish luxury multi-brand stores. Possible answers are sought to the following research question: How might the adoption of e-commerce platforms aff ect the international sales of multi-brand retailers? This paper presents a data analysis of the 15 most important Spanish fashion multi-brand retailers and the diff erent prospects of e-commerce today. Our analysis of online stores shows an open mentality when it comes to adapting to this new business model, but the late integration and inexperience of the majority of retailers limit their performance. Information from diff erent channels and further research through the collaboration of brands would have given us more detailed information regarding the current situation within this sector. The paper analyzes the current situation of e-commerce luxury fashion multi-brand stores and mainly focuses on the Spanish market, even though it also off ers a global overview.
