Low platelet count: Predictor of death and graft loss after liver transplantation

World Journal of Hepatology 2019年第1期11卷 99-108页

作者： pedro Beltrame Santiago rodriguez Ajacio Bandeira de Mello Brand?o Graduate Program in Medicine: Hepatology School of Medicine Universidade Federal de Ciências da Saúde dePorto Alegre (UFCSPA) Liver Transplantation Group Santa Casa de Misericórdia de Porto Alegre

BACKGROUND The impact of platelets on liver transplantation(LT) is well recognized, but not completely understood. Platelets exert dichotomous effects on the graft and on the patient. On the one hand, they are essential for primary hemostasis and tissue repair and regeneration. On the other hand, they support ischemia/reperfusion injury and inflammatory processes. Recent evidence has shown a new role for platelet count(PC) in predicting outcomes after *** To evaluate if low PC is a predictor of short-and long-term outcomes after *** Four hundred and eighty consecutive LT patients were retrospectively *** from the preoperative to the seventh postoperative day(POD) were considered. C-statistic analysis defined the ideal cutoff point for PC. Cox regression was performed to check whether low PC was a predictor of death,retransplantation or primary changes in graft function within one year after *** The highest median PC was 86 × 109/L [interquartile range(IQR) = 65–100 ×109/L] on seventh POD, and the lowest was 51 × 109/L(IQR = 38–71 × 109/L) on third POD. The C-statistic defined a PC < 70 × 109/L on fifth POD as the ideal cutoff point for predicting death and retransplantation. In the multivariate analysis, platelets < 70 × 109/L on 5 POD was an independent risk factor for death at 12 mo after LT [hazard ratio(HR) = 2.01; 95% confidence interval(CI) 1.06-3.79;P = 0.031]. In the Cox regression, patients with PC < 70 × 109/L on 5 POD had worse graft survival rates up to one year after LT(HR = 2.76; 95%CI 1.52-4.99; P =0.001).CONCLUSION PC < 70 × 109/L on 5 POD is an independent predictor of death in the first year after LT. These results are in agreement with other studies that indicate that low PC after LT is associated with negative outcomes.

Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three tech

Background: Intussusception is defined as a telescoping of a proximal gastrointestinal segment with its mesentery to a distal one, only 5% occur in adults and in colon the probability that it is caused by a malignant disease is up to 65%. Only 1% occurs in a retrograde manner, the rest occur in an anterograde manner. Aim: Describe the clinical presentation of an intussusception in the adult patient as well as its most frequent causes and possible complications that influence decision making for a definitive treatment. Case Presentation: A 66-year-old woman diagnosed with colon adenocarcinoma who underwent elective transverse colectomy and colonic anastomosis with an incidental finding of a transverse colon tumor in a retrograde intussusception was studied. Conclusion: In any adult patient with an intussusception especially in colon a neoplasia should be suspected and the affected segment should be resected without being reduced due to the risk of perforation and tumor dissemination.

CAPTURING COMPLEX,NON-LINEAR TEAM BEHAVIOURS DURING COMPETITIVE FOOTBALL PERFORMANCE

引用

Journal of Systems Science & Complexity 2013年第1期26卷 62-72页

作者： DUARTE Ricardo ARAUJO Duarte FOLGADO Hugo ESTEVES pedro MARQUES pedro DAVIDS Keith Faculty of Human Kinetics Technical University of Lisbon School of Science and Technology University of Evora Department of Performance Analysis Manchester City FCUnited Kingdom School of Human Movement Studies Queensland University of Technologies

This study investigated changes in the complexity （magnitude and structure of variability） of the collective behaviours of association football teams during competitive performance. Raw positional data from an entire competitive match between two professional teams were obtained with the ProZone tracking system. Five compound positional variables were used to investigate the collective patterns of performance of each team including： surface and geometrical centre. Analyses involve the coefficient （ApEn）, as well as the linear association between both area, stretch index, team length, team width, of variation （%CV） and approximate entropy parameters. Collective measures successfully captured the idiosyncratic behaviours of each team and their variations across the six time periods of the match. Key events such as goals scored and game breaks （such as half time and full time） seemed to influence the collective patterns of performance. While ApEn values significantly decreased during each half, the %CV increased. Teams seem to become more regular and predictable, but with increased magnitudes of variation in their organisational shape over the natural course of a match.

Pharmaceutical applications of spouted beds: A review on solid dosage forms

引用

Particuology 2019年第1期17卷 126-136页

作者： Luis Alexandre pedro de Freitas Faculdade de Ciencias Farmaceuticas de Ribeirao Preto University of Sao PauloVia do Cafe s/n. Campus USPRibeirao Preto14040-903Sao Paulo. Brazil

Spouted beds (SBs) have a long history of successful applications for preparation of solid dosage forms of pharmaceuticals. The well-known versatility of SBs, provided by different design and operational factors, and their efficient mixing of solids allow for engineering of technological characteristics of pharmaceutical solid forms. Particle properties like morphology, size, porosity, flowability, and dissolution rate can be improved by managing geometric and operational conditions for spouting. Drying is probably the most disseminated operation for pharmaceutical processing in SBs, and many studies have investigated drying of medicinal plant extracts such as achiote (Bixa orellana sp.), guarana (Paullinia cupana sp.), passion flower (Passiflora alata D.), and rosemary (Rosmarinus officinalis L.) with excellent pharmacotechnical and stability results. Another important application is coating of tablets and gelatin capsules, and previous studies have shown that SBs and spout–fluid beds may be advantageous over traditional pan coating, especially for polymeric film coating. Recently, an alternative process for improving drug bioavailability has involved preparation of β-cyclodextrin inclusion complexes in SBs. The first study to propose SBs for this pharmaceutical application explored the advantage of obtaining solid forms of inclusion complexes in just one step, and obtained expressive increases in drug solubility. The technique has been applied in subsequent studies on inclusion complexes of the medication carvedilol and uxi (Endopleura uchi L.) extracts.
