Correcting non cephalic presentation with moxibustion: study protocol for a multi-centre randomised controlled trial in general practice.

BACKGROUND Non cephalic presentation in childbirth involves various risks to both the mother and the foetus. The incidence in Spain is 3.8% of all full-term pregnancies. The most common technique used to end the gestation in cases of non cephalic presentation is that of caesarian section, and although it provokes a lower rate of morbi-mortality than does vaginal delivery in such situations, there remains the possibility of traumatic injury to the foetal head and neck, while maternal morbidity is also increased. The application of heat (moxibustion) to an acupuncture point, in order to correct non cephalic presentation, has been practised in China since ancient times, but as yet there is insufficient evidence of its real effectiveness. METHODS/DESIGN The experimental design consists of a multi-centre randomised controlled trial with three parallel arms, used to compare real moxibustion, sham moxibustion and the natural course of events, among pregnant women with a non cephalic presentation and a gestational duration of 33-35 weeks (estimated by echography). The participants in the trial will be blinded to both interventions. The results obtained will be analyzed by professionals, blinded with respect to the allocation to the different types of intervention. In addition, we intend to carry out a economic analysis. DISCUSSION This trial will contribute to the development of evidence concerning moxibustion in the correction of non cephalic presentations. The primary outcome variable is the proportion of cephalic presentations at term. As secondary outcomes, we will evaluate the proportion of cephalic presentations at week 38 of gestation, determined by echography, together with the safety of the technique, the specificity of moxibustion and the control of the blinding process. This study has been funded by the Health Ministry of the Andalusian Regional Government. TRIAL REGISTRATION Current Controlled Trials ISRCTN10634508.

Study protocol for a pragmatic randomised controlled trial in general practice investigating the effectiveness of acupuncture against migraine.

BACKGROUND Migraine is a chronic neurologic disease that can severely affect the patient's quality of life. Although in recent years many randomised studies have been carried out to investigate the effectiveness of acupuncture as a treatment for migraine, it remains a controversial issue. Our aim is to determine whether acupuncture, applied under real conditions of clinical practice in the area of primary healthcare, is more effective than conventional treatment. METHODS/DESIGN The design consists of a pragmatic multi-centre, three-armed randomised controlled trial, complemented with an economic evaluation of the results achieved, comparing the effectiveness of verum acupuncture with sham acupuncture, and with a control group receiving normal care only. Patients eligible for inclusion will be those presenting in general practice with migraine and for whom their General Practitioner (GP) is considering referral for acupuncture. Sampling will be by consecutive selection, and by randomised allocation to the three branches of the study, in a centralised way following a 1:1:1 distribution (verum acupuncture; sham acupuncture; conventional treatment). Secondly, one patient in three will be randomly selected from each of the acupuncture (verum or sham) groups for a brain perfusion study (by single photon emission tomography). The treatment with verum acupuncture will consist of 8 treatment sessions, once a week, at points selected individually by the acupuncturist. The sham acupuncture group will receive 8 sessions, one per week, with treatment being applied at non-acupuncture points in the dorsal and lumbar regions, using the minimal puncture technique. The control group will be given conventional treatment, as will the other two groups. DISCUSSION This trial will contribute to available evidence on acupuncture for the treatment of migraine. The primary endpoint is the difference in the number of days with migraine among the three groups, between the baseline period (the 4 weeks prior to the start of treatment) and the period from weeks 9 to 12. As a secondary aspect, we shall record the index of laterality and the percentage of change in the mean count per pixel in each region of interest measured by the brain perfusion tomography, performed on a subsample of the patients within the real and sham acupuncture groups.

The alcohol purchase task in young men from the general population.

BACKGROUND: The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, has been used among students and small clinical samples to obtain measures of alcohol demand but not in large, general population samples. METHODS: We administered the APT to a large sample of young men from the general population (Cohort Study on Substance Use Risk Factors). Participants who reported drinking in the past year (n=4790), reported on past 12 months alcohol use, on DSM-5 alcohol use disorder (AUD) criteria and on alcohol related consequences were included. RESULTS: Among the APT's demand parameters, intensity was 8.7 (SD=6.5) indicating that, when drinks are free, participants report a planned consumption of almost 9 drinks. The maximum alcohol expenditure (Omax) was over 35CHF (1CHF=1.1USD) and the demand became elastic (Pmax) at 8.4CHF (SD=5.6). The mean price at which the consumption was suppressed was 15.6CHF (SD=5.4). Exponential equation provided a satisfactory fit to individual responses (mean R(2): 0.8, median: 0.8). Demand intensity was correlated with alcohol use, number of AUD criteria and number of consequences (all r≥0.3, p<0.0001). Omax was correlated with alcohol use (p<0.0001). The elasticity parameter was weakly correlated with alcohol use in the expected direction. CONCLUSION: The APT measures are useful in characterizing demand for alcohol in young men in the general population. Demand may provide a clinically useful index of strength of motivation for alcohol use in general population samples.

Una visió general de les infraestructures de recerca a Europa – i recomanacions a LIBER

Les infraestructures de recerca inclouen diferent tipologies, des d’instal·lacions úniques a altres basades en xarxes. Típicament han sorgit de necessitats específiques d’una disciplina o bé multidisciplinàries. Les infraestructures de recerca produeixen, processen o gestionen volums heterogenis d’informació, tant grans com petits. Són les anomenades “fàbriques de dades científiques” del segle XXI. Comprenen diversos tipus de recursos d’informació com publicacions, col·leccions digitalitzades, objectes d’aprenentatge i dades de recerca. Les qüestions clau d'avui dia per a les infraestructures de recerca són el seu coneixement per part dels investigadors, i la seva viabilitat, sostenibilitat i interoperabilitat. El compromís de les biblioteques de recerca amb les infraestructures de recerca ha estat baix. Si bé això podria ser comprensible el 2005, quan les primeres prioritats per les inversions en infraestructures de recerca s’estaven definint, ara representa un gran buit en l'estratègia europea. Iniciatives clau com ESFRI no inclouen cap participació per part de biblioteques de recerca, amb excepció de DARIAH. La participació en projectes finançats per la Unió Europea (a través de LIBER o directament a través d'institucions) es va centrar (amb algunes excepcions) en les àrees de digitalització, patrimoni cultural i publicacions. Les biblioteques de recerca han d'esdevenir actors visibles en les discussions estratègiques sobre les infraestructures de recerca i haurien d’explorar activament la seva participació en les infraestructures de dades d'investigació. Accés Obert, Ciència Oberta (dades), les dades de recerca (infraestructures i gestió) són els catalitzadors per aconseguir que les biblioteques de recerca siguin presents pels investigadors més enllà de les humanitats i les ciències socials. "L'accés obert és global - però la seva aplicació és local '. Aquest és popular lema del projecte OpenAIRE i dóna a les biblioteques de recerca locals un paper important en el context europeu. Les dades de recerca són específiques segons les disciplines, però les polítiques, els fluxos de treball i les normes també s'han d'aplicar a nivell local. La creació d'infraestructures participatives amb la participació d’actors institucionals, nacionals i temàtics ha estat identificat per la Unió Europea com una tasca clau per a la dècada actual. El terme 'participatiu' també es considera d'importància fonamental per a l'estratègia de la política europea, ja que s'adapta molt bé amb la coordinació a nivell nacional i europeu per aconseguir una eficiència de costos i contribueix a evitar la duplicació de treball. Els principals desafiaments per a la construcció d'un ecosistema coherent, finançable i sostenible no es troben en les TIC, sinó més aviat en la gestió, la normativa, l'organització, els aspectes socioculturals, la confiança, i, per descomptat, els costos.

An alternative approach to fundamental general physics concepts

An alternative approach to the fundamental general physics concepts has been proposed. We demonstrate that the electrostatic potential energy of a discrete or a continuous system of charges should be stored by the charges and not the field. It is found that there is a possibility that any electric field has no energy density, as well as magnetic field. It is found that there is no direct relation between the electric or magnetic energy and photons. An alternative derivation of the blackbody radiation formula is proposed. It is also found that the zero-point of energy of electromagnetic radiation may not exist.

Urgences et médecins de premier recours: quelles perspectives? Quelle formation [Emergencies and general practitionners. Which prospects? Which education?].

Professionalisation of emergency medicine and triage before most of emergency consultations led to a major reduction in exposure of general practitionners (GP) to vital emergencies, which participates in reduction of their aptitudes to manage such emergencies. The risk for a GP to face a vital emergency is weak nowaday, but did not totaly disappear. Therefore, it seems important for the GPs to maintain the skills required to manage these emergencies properly. These skills would be capacity in recognizing symptoms and signs of alarm (red flags), applying life support, and sorting the patients correctly. These skills will be all the more important in the future, while the role of the GP could be reinforced in response to requirement of increased efficiency.

Ab initio absorption spectrum of NiO combining molecular dynamics with the embedded cluster approach in a discrete reaction field

We developed a procedure that combines three complementary computational methodologies to improve the theoretical description of the electronic structure of nickel oxide. The starting point is a Car-Parrinello molecular dynamics simulation to incorporate vibrorotational degrees of freedom into the material model. By means ofcomplete active space self-consistent field second-order perturbation theory (CASPT2) calculations on embedded clusters extracted from the resulting trajectory, we describe localized spectroscopic phenomena on NiO with an efficient treatment of electron correlation. The inclusion of thermal motion into the theoretical description allowsus to study electronic transitions that, otherwise, would be dipole forbidden in the ideal structure and results in a natural reproduction of the band broadening. Moreover, we improved the embedded cluster model by incorporating self-consistently at the complete active space self-consistent field (CASSCF) level a discrete (or direct) reaction field (DRF) in the cluster surroundings. The DRF approach offers an efficient treatment ofelectric response effects of the crystalline embedding to the electronic transitions localized in the cluster. We offer accurate theoretical estimates of the absorption spectrum and the density of states around the Fermi level of NiO, and a comprehensive explanation of the source of the broadening and the relaxation of the charge transferstates due to the adaptation of the environment

Three years of haemovigilance in a general university hospital.

The aim of this study is to describe a newly implemented haemovigilance system in a general university hospital. We present a series of short cases, highlighting particular aspects of the reports, and an overview of all reported incidents between 1999 and 2001. Incidents related to transfusion of blood products were reported by the clinicians using a standard preformatted form, giving a synopsis of the incident. After analysis, we distinguished, on the one hand, transfusion reactions, that are transfusions which engendered signs or symptoms, and, on the other hand, the incidents where management errors and/or dysfunctions took place. Over 3 years, 233 incidents were reported, corresponding to 4.2 events for 1000 blood products delivered. Of the 233, 198 (85%) were acute transfusion reactions and 35 (15%) were management errors and/or dysfunctions. Platelet units gave rise to statistically (P < 0.001) more transfusion reactions (10.7 per thousand ) than red blood cells (3.5 per thousand ) and fresh frozen plasma (0.8 per thousand ), particularly febrile nonhaemolytic transfusion reactions and allergic reactions. A detailed analysis of some of the transfusion incident reports revealed complex deviations and/or failures of the procedures in place in the hospital, allowing the implementation of corrective and preventive measures. Thus, the haemovigilance system in place in the 'Centre Hospitalier Universitaire Vaudois, CHUV' appears to constitute an excellent instrument for monitoring the security of blood transfusion.
