When nightclub security agents assault clients.

In 2006, a medico-legal consultation service devoted to adult victims of interpersonal violence was set up at the Lausanne University Hospital Centre, Switzerland: the Violence Medical Unit. Most patients are referred to the consultation by the Emergency Department. They are received by forensic nurses for support, forensic examination (in order to establish medical report) and community orientation. Between 2007 and 2009, among community violence, aggressions by security agents of nightclubs on clients have increased from 6% to 10%. Most of the victims are young men who had drunk alcohol before the assault. 25.7% presented one or several fractures, all of them in the head area. These findings raise questions about the ability of security agents of nightclubs to deal adequately with obviously risky situations and ensure client security.

Health intervention and decline in infant mortality rates. Milk depots in Spain (1900-1936)

The role of public health has been a central topic on the classical debate about the historical mortality decline in Europe. One of these health initiatives were the Milk Depots. Spain set up those centres from the late 19th century until the beginning of the Civil War. The goal of this paper is to evaluate the effect of this health intervention on the infant mortality decline during this period. This study works out three kinds of sources: Statistical Yearbooks, Official documents and local records produced by the same Milk Depot. It analyses data available for all the country and one local case such as the Barcelona’s Milk Depot (1904-1935). The main methodological issue deals with the measurement of the effect of the Milk Depot activities on the pattern of changes of infant mortality. Results suggest that Milk Depots have a positive but quite moderate effect on the improving of overall levels of child survival.

What if there was a stronger pharmaceutical price competition in Spain? When regulation has a similar effect to collusion

This paper examines statins competition in the Spanish pharmaceutical market, where prices are highly regulated, and simulates a situation in which there is unrestricted price competition. A nested logit demand model is estimated with a panel of monthly data for pharmaceuticals prescribed from 1997 to 2005. The simulation indicates that the regulation of prices is similar in its effects to cooperation among producers, since the regulated prices are close to those that would be observed in a scenario of perfect collusion. Freedom to set prices and a regulatory framework with appropriate incentives would result in a general reduction in prices and may make the current veiled competition in the form of discounts to pharmacists become more visible. The decrease in prices would be partially offset by an increase in consumption but the net effect would be an overall decrease in expenditure. The counterfactual set-up would also lead to important changes in the market shares of both manufacturers and active ingredients, and a reversal of generic drugs. Therefore, pro-competitive regulation would be welfare-enhancing but would imply winners and losers.

Optimal coexistence of long-term and short-term contracts in labor Markets

We consider a market where firms hire workers to run their projects and such projects differ in profitability. At any period, each firm needs two workers to successfully run its project: a junior agent, with no specific skills, and a senior worker, whose effort is not verifiable. Senior workers differ in ability and their competence is revealed after they have worked as juniors in the market. We study the length of the contractual relationships between firms and workers in an environment where the matching between firms and workers is the result of market interaction. We show that, despite in a one-firm-one-worker set-up long-term contracts are the optimal choice for firms, market forces often induce firms to use short-term contracts. Unless the market only consists of firms with very profitable projects, firms operating highly profitable projects offer short-term contracts to ensure the service of high-ability workers and those with less lucrative projects also use short-term contracts to save on the junior workers' wage. Intermediate firms may (or may not) hire workers through long-term contracts.

The de facto independence of regulatory agencies and its consequences for policy making and regulatory outcomes

This dissertation focuses on the practice of regulatory governance, throughout the study of the functioning of formally independent regulatory agencies (IRAs), with special attention to their de facto independence. The research goals are grounded on a "neo-positivist" (or "reconstructed positivist") position (Hawkesworth 1992; Radaelli 2000b; Sabatier 2000). This perspective starts from the ontological assumption that even if subjective perceptions are constitutive elements of political phenomena, a real world exists beyond any social construction and can, however imperfectly, become the object of scientific inquiry. Epistemologically, it follows that hypothetical-deductive theories with explanatory aims can be tested by employing a proper methodology and set of analytical techniques. It is thus possible to make scientific inferences and general conclusions to a certain extent, according to a Bayesian conception of knowledge, in order to update the prior scientific beliefs in the truth of the related hypotheses (Howson 1998), while acknowledging the fact that the conditions of truth are at least partially subjective and historically determined (Foucault 1988; Kuhn 1970). At the same time, a sceptical position is adopted towards the supposed disjunction between facts and values and the possibility of discovering abstract universal laws in social science. It has been observed that the current version of capitalism corresponds to the golden age of regulation, and that since the 1980s no government activity in OECD countries has grown faster than regulatory functions (Jacobs 1999). Following an apparent paradox, the ongoing dynamics of liberalisation, privatisation, decartelisation, internationalisation, and regional integration hardly led to the crumbling of the state, but instead promoted a wave of regulatory growth in the face of new risks and new opportunities (Vogel 1996). Accordingly, a new order of regulatory capitalism is rising, implying a new division of labour between state and society and entailing the expansion and intensification of regulation (Levi-Faur 2005). The previous order, relying on public ownership and public intervention and/or on sectoral self-regulation by private actors, is being replaced by a more formalised, expert-based, open, and independently regulated model of governance. Independent regulation agencies (IRAs), that is, formally independent administrative agencies with regulatory powers that benefit from public authority delegated from political decision makers, represent the main institutional feature of regulatory governance (Gilardi 2008). IRAs constitute a relatively new technology of regulation in western Europe, at least for certain domains, but they are increasingly widespread across countries and sectors. For instance, independent regulators have been set up for regulating very diverse issues, such as general competition, banking and finance, telecommunications, civil aviation, railway services, food safety, the pharmaceutical industry, electricity, environmental protection, and personal data privacy. Two attributes of IRAs deserve a special mention. On the one hand, they are formally separated from democratic institutions and elected politicians, thus raising normative and empirical concerns about their accountability and legitimacy. On the other hand, some hard questions about their role as political actors are still unaddressed, though, together with regulatory competencies, IRAs often accumulate executive, (quasi-)legislative, and adjudicatory functions, as well as about their performance.

Stochastic time-concentration activity models for cytotoxicity in 3D brain cell cultures.

BACKGROUND: In vitro aggregating brain cell cultures containing all types of brain cells have been shown to be useful for neurotoxicological investigations. The cultures are used for the detection of nervous system-specific effects of compounds by measuring multiple endpoints, including changes in enzyme activities. Concentration-dependent neurotoxicity is determined at several time points. METHODS: A Markov model was set up to describe the dynamics of brain cell populations exposed to potentially neurotoxic compounds. Brain cells were assumed to be either in a healthy or stressed state, with only stressed cells being susceptible to cell death. Cells may have switched between these states or died with concentration-dependent transition rates. Since cell numbers were not directly measurable, intracellular lactate dehydrogenase (LDH) activity was used as a surrogate. Assuming that changes in cell numbers are proportional to changes in intracellular LDH activity, stochastic enzyme activity models were derived. Maximum likelihood and least squares regression techniques were applied for estimation of the transition rates. Likelihood ratio tests were performed to test hypotheses about the transition rates. Simulation studies were used to investigate the performance of the transition rate estimators and to analyze the error rates of the likelihood ratio tests. The stochastic time-concentration activity model was applied to intracellular LDH activity measurements after 7 and 14 days of continuous exposure to propofol. The model describes transitions from healthy to stressed cells and from stressed cells to death. RESULTS: The model predicted that propofol would affect stressed cells more than healthy cells. Increasing propofol concentration from 10 to 100 μM reduced the mean waiting time for transition to the stressed state by 50%, from 14 to 7 days, whereas the mean duration to cellular death reduced more dramatically from 2.7 days to 6.5 hours. CONCLUSION: The proposed stochastic modeling approach can be used to discriminate between different biological hypotheses regarding the effect of a compound on the transition rates. The effects of different compounds on the transition rate estimates can be quantitatively compared. Data can be extrapolated at late measurement time points to investigate whether costs and time-consuming long-term experiments could possibly be eliminated.

The Role of the European Union in the Processes to Ban Cluster Munitions

At the end of 2008 the Convention on Cluster Munitions (CCM) that outlawed almost all types of cluster munitions was signed. It was the product of the so-called Oslo process, which had been set up two years earlier as a reaction to the failure to add a new protocol banning cluster munitions to the Convention on Certain Conventional Weapons (CCW). The position of the EU in these two processes was ambivalent: on the one hand it belonged to the strongest proponents for a new protocol within the CCW, but on the other hand the member states were in general not able to act jointly in the Oslo Process. According to this working paper especially the aspect of national security and the related relationship to the United States influenced the stances of many member states and complicated the formation of a common European position. There were common normative values of the EU detected, which played a role in the CCW, but they were only secondary to other interests of the member states.

Drug Resistance Patterns among Hospitalized Tuberculous Patients in Rio de Janeiro, Brazil, 1993-1994

The purpose of this study was to analyze the prevalence and risk factors for drug resistance among hospitalized patients in two tertiary care centers, an acquired immunodeficiency syndrome (AIDS) reference center and a sanatorium, in Rio de Janeiro, Brazil. From 1993-1994, 389 patients were diagnosed as having tuberculosis (TB). Isolates from 265 patients were tested for in vitro susceptibility to rifampin and isoniazid. Resistance to one or more drugs was detected in 44 patients (16.6%) and was significantly more common among recurrent cases in both hospitals (p=0.03 in the AIDS center and p=0.001 in the sanatorium). Twenty seven patients (10.2%) had isolates resistant to both isoniazid and rifampin. Multi-drug resistance was associated with human immunodeficiency virus (HIV) infection among patients who had never been treated for TB. In conclusion, drug-resistant TB is high in hospitalized patients in Rio de Janeiro, especially among HIV infected patients. Therefore, measures to control TB and prevent nosocomial transmission need urgently to be set up in the Brazilian hospitals.

New bench test for venous cannula performance assessment.

Cannula design is of prime importance for venous drainage during cardiopulmonary bypass (CPB). To evaluate cannulas intended for CPB, an in vitro circuit was set up with silicone tubing between the test cannula encased in a movable preload reservoir and another static reservoir. The pressure-drop (DeltaP) value (P-drainage - P-preload) was measured using Millar pressure transducers. Flow rate (Q) was measured using an ultrasound flowmeter. Data display and data recording were controlled using a LabView application, custom made particularly for our experiments. Our results demonstrated that DeltaP, Q, and cannula resistance (DeltaP/Q) values were significantly decreased when the cannula diameter was increased for Smart and Medtronic cannulas. Smartcanula showed 36% and 43% less resistance compared to Medtronic venous and Medtronic femoral cannulas, respectively. The cannula shape (straight- or curved-tips) did not affect the DLP cannula resistance. Out of five cannulas tested, the Smartcanula outperforms the other commercially available cannulas. The mean (DeltaP/Q) values were 3.3 +/- 0.08, 4.07 +/- 0.08, 5.58 +/- 0.10, 5.74 +/- 0.15, and 6.45 +/- 0.15 for Smart, Medtronic, Edwards, Sarns, and Gambro cannulas, respectively (two-way ANOVA, p < 0.0001). In conclusion, the present assay allows discrimination between different forms of cannula with high or low lumen resistance.

IPH gives evidence to NI Assembly Health Committee Inquiry into Obesity

IPH Chief Executive, Dr Jane Wilde gave evidence to the Northern Ireland Assembly Health Committee inquiry into obesity. Dr Wilde recommended the following: Supporting the Department of Health’s strategic approach based on an understanding of the nature and complexity of obesity. Urgent and short term action to coordinate current activities and ensure focus on the most vulnerable. Exploring new forms and incentives to promote cross departmental work. Setting intermediate outcomes and targets Building stronger links between research, policy and practice, for example asking the Health Committee to set up a round table of researchers and policy makers Working systematically and transparently to identify key areas for cooperation with UK, Ireland and Europe Drawing from IPH work and other research, Dr Wilde briefed the Health Committee on the extent and impact of obesity, reasons for rising levels of obesity and the need for a stronger strategic response. She highlighted the importance of cross government action, the responsibilities of those beyond the health sector and the need for stronger evidence-informed policy and practice.

DHSSPS Consultation on smoking in enclosed public places and workplaces

The Institute of Public Health welcomes the current consultation on smoking in enclosed workplaces and public places. Having considered the three options given the Institute strongly supports option 5c – “a total ban on smoking in all enclosed workplaces and public places”. This clearly outlines that a total ban on smoking in all enclosed public places and workplaces is the only option which will adequately protect the health of all workers and contribute to reducing the prevalence of smoking in the population of Northern Ireland.As an organisation set up to promote North South co-operation we believe that a similar approach to smoking in public places and workplaces should be taken to that in the Republic of Ireland where there is clear evidence that such policies are practical, well supported and effective.

Disseny i optimització de membranes compòsit amb xarxes metal•loorgàniques per a nanofiltració i separacions de gasos

Projecte de recerca elaborat a partir d’una estada a la Katholieke Universiteit Leuven, Belgium, entre 2007 i 2009. Aquest projecte descriu la síntesi i aplicació de nous tipus de membranes compòsit basades en xarxes metal•loorgàniques (MOFs). Aquestes es van seleccionar tenint en compte les seves propietats estructurals per tal de discriminar les espècies a separar en funció de la seva mida molecular. Les membranes obtingudes s'han aplicat satisfactòriament tant en separacions líquides, concretament en nanofiltració resistent a dissolvents (SRNF), i en separació de parells de gasos com CO2/CH4, CO2/N2 i H2/CO2. Els resultats obtinguts posen de manifest l'obtenció de membranes sense defectes i amb rendiments prometedors, en la majoria dels casos, amb permeabilitats i selectivitats superiors a membranes purament polimèriques. Tanmateix s'ha desenvolupat un nou equipament d'alt rendiment (HT) per a separacions de gasos que inclou un mòdul que permet realitzar 16 experiments simultàniament. Els resultats obtinguts amb el nou equip són comparables amb els obtinguts amb mòduls convencionals, i alhora presenten una millor reproduïbilitat. Finalment, s'ha establert un nou mètode per a obtenir membranes per a SRNF, que han estat aplicades en processos de separació de catalitzadors homogenis en dissolvents polars apròtics i s'han caracteritzat emprant la tècnica d'espectroscòpia d'annihilació de positrons, que ha permès establir per primer cop una relació entre les propietats estructurals de les membranes a nivell molecular i el seu rendiment en les aplicacions anteriors.

Subclinical peripheral synovitis detected by echography in patients with axial Spondyloarthritis

Background: patients with axial Spondyloarthritis (SD), even withoutany obvious peripheral joint synovitis, often complain of pain in thejoints of arms and legs. Several musculoskeletal ultrasound (US)scores developed in rheumatoid arthritis have demonstrated theircapacity of discovering subclinical synovitis which were relevant interm of disease activity and for treatment strategies. None of thesescores however have been, to our knowledge, applied tospondyloarthritis patients.Objectives: to determine if subclinical synovitis can be detected byechography in patients with SD and if these synovitis are relevantcompared with RA and controls.Methods: the Swiss Sonography in Arthritis and Rheumatism(SONAR) group has developed a reproducible semi-quantitative scorefor RA using OMERACT criteria for synovitis. The score includes Bmode and Doppler mode. 35 out of 40 enrolled SD patients fulfillingthe 2010 diagnostic criteria were evaluated according to the SONARscore. In none of them, peripheral synovitis was clearly demonstrated,although some have or reported recurrent peripheral joint pain. Thescore was also applied to 20 matched controls and 40 consecutive RApatients (RA). 19 of them were in remission (DAS: <2.6), 10 with alow activity (DAS: 2.6 <>3.4) and 11 with a moderate activity disease(DAS: 3.5 <>5.1). All the patients and the controls had a completeclinical, biological and auto-evaluation assessment (joint pain andswelling counts, DAS28, HAQ, BASDAI BASMI, BASFI, m-SACRAH).The ultra-sonographer was blind to all these parameters.Results: a B mode score >8, was set up as a cut-off value forsignificant synovitis as only 10% of the controls (median: 5.9 ± 2.2)and 90% of active RA had a higher score .34% of SD had significantsynovitis which remained mostly mild. Their median B mode score(12 ± 1.6) was higher but not significantly than in remission Ra (7.1 ±3.4). Only active RA (DAS >3.5) had significant higher echographicscores: B mode (17 ± 11), Doppler score and cumulative score forsynovitis grade >1. BASDAI, BASFI, BASMI, m-SACRAH, DAS28 andCRP were not significantly different in SD patients with or withoutsynovitis.Conclusions: some patients with axial Spondyloarthritis havesubclinical but significant peripheral synovitis detected by echography.The impact of these synovitis remains uncertain as their presencedoes not seem to significantly influence disease activity and functionevaluation tools.
