Diabetes mellitus: Polymorphonuclear leukocyte (PMN) filtration parameters and PMN membrane fluidity after chemotactic activation
1999
Abstract The goal of this research was to determine leukocyte rheology at baseline and after chemotactic activation in type I and type II diabetics. In 19 normal subjects, 21 type I diabetics, and 16 type II diabetics at baseline and after in vitro chemotactic activation (prolonged for 5 and 15 minutes) with two stimulating agents (4-phorbol 12-myristate 13-acetate [PMA] and N -formyl-methionyl-leucyl-phenylalanine [fMLP]), we evaluated polymorphonuclear (PMN) filtration parameters (using a St. George filtrometer [Carri-Med, Dorking, UK] and considering the initial relative flow rate [IRFR] and the concentration of clogging particles [CP]) and PMN membrane fluidity (obtained by marking PMNs…
The Respect of Recommendations Provided in an International Travelers' Medical Service: Far From the Cup to the Lips
2013
Equipe plutôt EA Pôle MERS CT3 EJ3; Background: It is not clearly known how frequently the recommendations given to travelers are followed, and what factors could encourage compliance with these recommended measures. Methods: Adults consulting at a Medical Department for International Travelers (International Travelers' Medical Services, ITMS) in October and November 2010 were asked to answer a questionnaire before their journey. They were also contacted for a post-travel telephone interview to determine whether they had followed the recommendations regarding vaccinations and malaria prevention, and the reasons for poor or noncompliance with these recommendations. Results A total of 353 tra…
Clinical benefits of a Bayesian model for plasma-derived factor VIII/VWF after one year of pharmacokinetic-guided prophylaxis in severe/moderate hemo…
2021
Abstract Introduction Individual pharmacokinetic (PK) profiling in hemophilia A (HA) helps to individualize prophylaxis using population PK models (popPK). A specific popPK model for plasma-derived factor VIII containing von-Willebrand Factor (pdFVIII/VWF) was developed. Aim To compare standard versus PK-driven prophylaxis, using a generic or a specific popPK model for pdFVIII/VWF. Materials and methods A prospective study conducted in HA patients in prophylaxis with pdFVIII/VWF (Fanhdi®) comparing three one-year study periods: (1) standard prophylaxis, (2) PK-guided prophylaxis using a generic pdFVIII popPK model which described FVIII activity irrespective of FVIII concentrate, and (3) PK-…
Is intravesical instillation of hyaluronic acid and chondroitin sulfate useful in preventing recurrent bacterial cystitis? A multicenter case control…
2015
Abstract Objective Urinary tract infections (UTIs) are common in the female population and, over a lifetime, about half of women have at least one episode of UTI requiring antibiotic therapy. The aim of the current study was to compare two different strategies for preventing recurrent bacterial cystitis: intravesical instillation of hyaluronic acid (HA) plus chondroitin sulfate (CS), and antibiotic prophylaxis with sulfamethoxazole plus trimethoprim. Materials and methods This was a retrospective review of two different cohorts of women affected by recurrent bacterial cystitis. Cases (experimental group) were women who received intravesical instillations of a sterile solution of high concen…
Immune Tolerance Induction in Hemophilia A: A Review
2003
In this article, a comparative analysis of the data stemming from the studies conducted in the field of immune tolerance treatment (ITT) of hemophilia A was attempted. Comparisons are difficult because previous studies differ in many respects, including the dosage of factor (F) VIII, the number of FVIII administrations per day, the association with immunosuppressive drugs (prednisone, cyclophosphamide), and, most importantly, the definition of success in terms of the reacquisition of tolerance. However, a number of variables consistently influenced outcome: the inhibitor titer, either the maximum one or the one assayed before immune tolerance (IT) start and age. As to the FVIII dose, result…
Low-molecular-weight heparin to prevent recurrent venous thromboembolism in pregnancy: Rationale and design of the Highlow study, a randomised trial …
2016
Summary Background Women with a history of venous thromboembolism (VTE) have a 2% to 10% absolute risk of VTE recurrence during subsequent pregnancies. Therefore, current guidelines recommend that all pregnant women with a history of VTE receive pharmacologic thromboprophylaxis. The optimal dose of low-molecular-weight heparin (LMWH) for thromboprophylaxis is unknown. In the Highlow study (NCT 01828697; www.highlowstudy.org ), we compare a fixed low dose of LMWH with an intermediate dose of LMWH for the prevention of pregnancy-associated recurrent VTE. We present the rationale and design features of this study. Methods The Highlow study is an investigator-initiated, multicentre, internation…
Fatal multi-organ failure following anaphylactic shock induced by ceftriaxone
2014
In the latest years, based on the wide use of cephalosporins for antibiotic therapy, a large interest focused on the identification of causal relationship of adverse reactions after their prescription. We report a case of fatal anaphylactic shock following the administration of ceftriaxone in a woman who had tolerated the previous exposure to the drug. This case adds a contribution to the few cases reported in literature to further suggest the possibility of severe anaphylaxis after the administration of ceftriaxone even in patients without any previous reaction to this drug.
The impurity of praxis : Arendt and Agamben
2023
AbstractIf politics is understood as a foundational and open-ended activity, a general problem that arises from such a framing concerns the question of how to sustain the possibility of continuous openings without converting action into permanence and closure. In this article, we approach this problematic by treating Hannah Arendt as an exemplary figure in the current of political thought that emphasizes the indeterminate nature of action. We focus more specifically on how Arendt addressed the question of sustaining action by exploring the role of forgiveness, promises, divided power, and principles of action in her thought. While we show that the task of sustaining the indeterminacy of act…
Acute psychosocial stress effects on memory performance: Relevance of age and sex.
2018
In recent decades, there has been a growing interest in investigating the effects of chronic and acute stress on cognitive processes, especially memory performance. However, research focusing on acute stress effects has reported contradictory findings, probably due to the many factors that can moderate this relationship. In addition to factors related to the individual, such as sex and age, other factors, such as the type of memory assessed, can play a critical role in the direction of these effects. This review summarizes the main findings of our research group and others about the effects of acute psychosocial stress on memory performance in young and older people of both sexes, taking in…
Cortisol and the aging brain: Hypothalamic-pituitary-adrenal axis and cognitive performance in older people.
2015
One of the greatest achievements in modern society is the increase in life expectancy. This increment is so great that children born after 2011 have a one in three chance of reaching their 100th birthday, and specifically in Europe, a quarter of the population will be over 60 years of age by 2020 (European Commission, 2014). This is an important change in society that is occurring for the first time in human history and producing new challenges that need to be addressed, especially those concerning age-related health problems. In this regard, one of the main aims of new research programs, such as Horizon 2020 in Europe, is to increase the possibilities of keeping older people healthy and in…
