Secondary prevention after cerebral ischaemia of presumed arterial origin: is aspirin still the touchstone?

Patients who have had a transient ischaemic attack or nondisabling ischaemic stroke of presumed arterial origin have an annual risk of death from all vascular causes, non-fatal stroke, or non-fatal myocardial infarction that ranges between 4% and 11% without treatment. In the secondary prevention of these vascular complications the use of aspirin has been the standard treatment for the past two decades. Discussions about the dose of aspirin have dominated the issue for some time, although there is no convincing evidence for any difference in effectiveness in the dose range of 30-1300 mg/day. A far greater problem is the limited degree of protection offered by aspirin: the accumulative evidence from trials with aspirin alone and only for cerebrovascular disease of presumed arterial origin as qualifying event indicates that a dose of aspirin of at least 30 mg/day prevents only 13% of serious vascular complications

Wat gebeurt er als je consumenten beloont voor mond tot mond reclame?

Mond tot mond communicatie heeft veel invloed op productkeuzes en aankoopbeslissingen van consumenten. Omdat dit zo veel invloed heeft, proberen marketeers deze communicatie te stimuleren, bijvoorbeeld door consumenten te belonen voor een aanbeveling. In dit onderzoek richten we ons op de vraag hoe de ontvanger van een beloonde aanbeveling hier op reageert. We argumenteren dat de introductie van een beloning als gevolg heeft dat een aanbeveling zowel aspecten krijgt van een vriendschapsrelatie als van een verkooprelatie. We tonen aan dat de relatieve saillantie van deze relaties zowel invloed heeft op de beoordeling van de aanbeveler als op de neiging om op de aanbeveling in te gaan. We laten ook zien dat dit een onbewust proces is. Tevens blijkt dat het onthullen van een !nanciële beloning in dergelijke interacties een positieve invloed heeft. Marketingimplicaties voor het belonen van aanbevelingen worden besproken

Fundus first laparoscopic cholecystectomy in patients with gall stone disease and the Fitz-Hugh-Curtis syndrome

Background: To present this experience using the fundus-first technique during laparoscopic cholecystectomy for the management of symptomatic gall stone disease with an intra-operative finding of Fitz-Hugh-Curtis syndrome.Methods: This is a prospective review of patients who had the fundus-first dissection during laparoscopic cholecystectomy. The study was carried out at the Jos University Teaching Hospital (JUTH), and FOMAS hospital, both of which are tertiary hospitals located in Jos. Patients were recruited from January 2017 - January 2019. All patients undergoing laparoscopic cholecystectomy who had an intraoperative diagnosis of Fitz-Hugh-Curtis syndrome, and who had the fundus-first dissection, were included in the study. Patients who had fundus-first dissection for indications other than Fitz-Hugh-Curtis syndrome, were excluded from the study. Demographic and clinical information of patients included age, sex, duration of surgery, complications, and duration of hospital stay. Descriptive statistics were applied.Results: A total of 76 patients had elective laparoscopic cholecystectomies over the study period. Of that number, 17 (22.4%) patients had an intra- operative diagnosis of Fitz-Hugh-Curtis syndrome, and had the fundus-first dissection. The mean patient age was 46.3 years (SD = 11.7 years). All patients were female. The mean operating time was 70 minutes (SD = 23 minutes). The duration of hospital stay was 24 hours. There was one conversion due to uncontrollable intraoperative bleeding.Conclusions: This study revealed that the fundus-first dissection is suitable for removing the gall bladder during laparoscopic cholecystectomy in patients with gall stone disease, and an intraoperative finding of Fitz-Hugh-Curtis syndrome

Taalabstractie in communicatie over producten: wanneer beschrijven we een ervaring met een product concreet en wanneer abstract?

Dit artikel laat zien dat er in mond-tot-mondreclame over producten een systematische vertekening optreedt in het taalgebruik. Net als in eerder onderzoek naar taalabstractie in beschrijvingen van interpersoonlijk gedrag, gebruiken mensen bij het beschrijven van productervaringen meer abstracte taal wanneer de ervaring overeenkomt met de verwachting die men vooraf heeft

Early time course of major bleeding on antiplatelet therapy after TIA or ischemic stroke

Objective: To study the early time course of major bleeding and its subtypes in patients with cerebral ischemia on dual and single antiplatelet therapy. Methods: We performed a post hoc analysis on individual patient data from 6 randomized clinical trials (Clopidogrel Versus Aspirin in Patients at Risk of Ischaemic Events [CAPRIE], Second European Stroke Prevention Study [ESPS-2], Management of Atherothrombosis With Clopidogrel in High Risk Patients [MATCH], Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management, and Avoidance [CHARISMA], European/Australasian Stroke Prevention in Reversible Ischaemia Trial [ESPRIT], and Prevention Regimen for Effectively Avoiding Second Strokes [PRoFESS]) including 45,195 patients with a TIA or noncardioembolic ischemic stroke. We studied incidence rates of bleeding per antiplatelet regimen stratified by time from randomization (≤30, 31–90, 91–180, 181–365, >365 days). We calculated incidence rates per trial and pooled estimates with random-effects meta-analysis. We performed Poisson regression to assess differences between time periods with adjustment for age and sex. Results: The incidence of major bleeding on aspirin plus clopidogrel and aspirin plus -dipyridamole was highest in the first 30 days, 5.8 and 4.9 per 100 person-years, respectively, and was significantly higher than at 31 to 90 days (rate ratio 1.98, 95% confidence interval 1.16–3.40 for aspirin plus clopidogrel; rate ratio 1.94, 95% confidence interval 1.24–3.03 for aspirin plus dipyridamole). Incidence rates on aspirin and clopidogrel monotherapy were 2.8 and 2.5 per 100 person-years, respectively, in the first 30 days, with no significant change over time. The time course was similar for gastrointestinal bleeds. There was no early excess of intracranial hemorrhage in patients on either dual or single antiplatelet therapy. Conclusion: Dual antiplatelet therapy is associated with high early risks of major and gastrointestinal bleeding that decline after the first month in trial cohorts

Ulocuplumab (BMS-936564 / MDX1338): a fully human anti-CXCR4 antibody induces cell death in chronic lymphocytic leukemia mediated through a reactive oxygen species-dependent pathway.

The CXCR4 receptor (Chemokine C-X-C motif receptor 4) is highly expressed in different hematological malignancies including chronic lymphocytic leukemia (CLL). The CXCR4 ligand (CXCL12) stimulates CXCR4 promoting cell survival and proliferation, and may contribute to the tropism of leukemia cells towards lymphoid tissues. Therefore, strategies targeting CXCR4 may constitute an effective therapeutic approach for CLL. To address that question, we studied the effect of Ulocuplumab (BMS-936564), a fully human IgG4 anti-CXCR4 antibody, using a stroma--CLL cells co-culture model. We found that Ulocuplumab (BMS-936564) inhibited CXCL12 mediated CXCR4 activation-migration of CLL cells at nanomolar concentrations. This effect was comparable to AMD3100 (Plerixafor--Mozobil), a small molecule CXCR4 inhibitor. However, Ulocuplumab (BMS-936564) but not AMD3100 induced apoptosis in CLL at nanomolar concentrations in the presence or absence of stromal cell support. This pro-apoptotic effect was independent of CLL high-risk prognostic markers, was associated with production of reactive oxygen species and did not require caspase activation. Overall, these findings are evidence that Ulocuplumab (BMS-936564) has biological activity in CLL, highlight the relevance of the CXCR4-CXCL12 pathway as a therapeutic target in CLL, and provide biological rationale for ongoing clinical trials in CLL and other hematological malignancies

DTMp : a comenius 2.1 project to produce a differentiated teaching module for primary school trainee teachers

This work was supported by the EU through Comenius 2.1 granr no. 118096 for the DTMp Project.As European classrooms become more heterogeneous, the movement towards inclusive education becomes more urgent as well as more challenging. This paper describes the process of developing and running a proposal for a Comenius 2.1 project aimed at developing training materials for the preparation of pre-service teachers in responding to diversity in primary classrooms. The project, started in October 2004, has collected the concerns and experiences of responding to diversity of 35 teachers (5 each from 7 different countries) through semi-structured interviews, and produced the first draft of a multilingual handbook for trainees. The handbook in hard copy and web-based format, will be piloted in 2005-06 in the seven participating countries, namely Malta (coordinator), Czech Republic, Germany, Lithuania, Netherlands, Sweden and the UK. This paper will focus on the process of trans-European sharing of research and development of the training course.peer-reviewe

Prenatal ultrasound diagnosis of anterior abdominal wall defects in sub Saharan Africa; simple but often missed

Background: Congenital anterior abdominal wall defects (AAWD) is a spectrum of abdominal wall defects that includes omphalocele, gastroschisis, bladder exstrophy, cloacal exstrophy, prune belly syndrome and pentalogy of Cantrell. Early Prenatal diagnosis of AAWD provides opportunity for abnormal karyotypes screening and planned delivery in a specialized centre. Ultrasound can detect these defects during pregnancy. This study aims to evaluate the detection rate of AAWD during routine obstetric ultrasonography in our region.Methods: A retrospective study of all patients that presented with AAWD to our centre from January 2008 to July 2020. Data included patient’s age, sex, birth weight, diagnosis, resuscitation time, outcome, maternal age, parity and antenatal ultrasound scan (USS) records. Antenatal USS before 12 weeks only, were excluded. Data analysed using excel.Results: Of the 140 with AAWD, 84.29% had omphalocele, 10% gastroschisis, 2.14% prune belly syndrome and 0.71% each with bladder exstrophy, cloacal exstrophy and pentalogy of Cantrell. There were 123 booked pregnancies. Majority (112) had antenatal care elsewhere while 11 attended our Centre. Ultrasonography of 108 pregnancies scanned at12 weeks or beyond, had 4 confirmed prenatal diagnosis of AAWD. All done in our centre. Mean gestational age at diagnosis was 24weeks. Outcome was rupture1 (25%) and 25% mortality (prenatally diagnosed) and 51.92% mortality for patients with missed diagnosis.Conclusions: Our obstetric ultrasound detection rate of AAWD is very low. There is a need for improvement in training to improve perinatal care of these defects

A System F accounting for scalars

The Algebraic lambda-calculus and the Linear-Algebraic lambda-calculus extend the lambda-calculus with the possibility of making arbitrary linear combinations of terms. In this paper we provide a fine-grained, System F-like type system for the linear-algebraic lambda-calculus. We show that this "scalar" type system enjoys both the subject-reduction property and the strong-normalisation property, our main technical results. The latter yields a significant simplification of the linear-algebraic lambda-calculus itself, by removing the need for some restrictions in its reduction rules. But the more important, original feature of this scalar type system is that it keeps track of 'the amount of a type' that is present in each term. As an example of its use, we shown that it can serve as a guarantee that the normal form of a term is barycentric, i.e that its scalars are summing to one
