Prevention in underground construction with sequential excavation method

This paper aims to describe the Sequential Excavation Method, used for excava-tion in underground works, as well as the related risks and preventive measures. This method has characteristics that differentiate it from other tunnelling techniques: it uses a larger number of workers and equipment; it has a high concurrency of tasks with various workers and equip-ment quite exposed to hazards; and it uses many potentially aggressive chemicals. Firstly, it is given a broad overview of this issue. Afterwards, it will be presented the results of a survey to a sample of experienced technicians, aimed at gauging the relevance of a set of guidelines relat-ing to the design and work phases, applicable to the domestic market and prepared following technical visits to works abroad.

Cost-Effectiveness of High, Moderate and Low-Dose Statins in the Prevention of Vascular Events in the Brazilian Public Health System

Background:Statins have proven efficacy in the reduction of cardiovascular events, but the financial impact of its widespread use can be substantial.Objective:To conduct a cost-effectiveness analysis of three statin dosing schemes in the Brazilian Unified National Health System (SUS) perspective.Methods:We developed a Markov model to evaluate the incremental cost-effectiveness ratios (ICERs) of low, intermediate and high intensity dose regimens in secondary and four primary scenarios (5%, 10%, 15% and 20% ten-year risk) of prevention of cardiovascular events. Regimens with expected low-density lipoprotein cholesterol reduction below 30% (e.g. simvastatin 10mg) were considered as low dose; between 30-40%, (atorvastatin 10mg, simvastatin 40mg), intermediate dose; and above 40% (atorvastatin 20-80mg, rosuvastatin 20mg), high-dose statins. Effectiveness data were obtained from a systematic review with 136,000 patients. National data were used to estimate utilities and costs (expressed as International Dollars - Int$). A willingness-to-pay (WTP) threshold equal to the Brazilian gross domestic product per capita (circa Int$11,770) was applied.Results:Low dose was dominated by extension in the primary prevention scenarios. In the five scenarios, the ICER of intermediate dose was below Int$10,000 per QALY. The ICER of the high versus intermediate dose comparison was above Int$27,000 per QALY in all scenarios. In the cost-effectiveness acceptability curves, intermediate dose had a probability above 50% of being cost-effective with ICERs between Int$ 9,000-20,000 per QALY in all scenarios.Conclusions:Considering a reasonable WTP threshold, intermediate dose statin therapy is economically attractive, and should be a priority intervention in prevention of cardiovascular events in Brazil.

Violence: les femmes font confiance au milieu médical [Partner violence: women trust health professionals]

In 2008, the department of gynaecology and obstetrics of a university hospital centre implemented a program addressing interpersonal partner violence (screening, prevention and care of the patient victims). A qualitative survey was conducted to identify the needs and feelings of patients. The results show that patients are in favour of being actively and directly questioned about violence during the consultation and that they trust medical doctors and nurses to help and support them.

The Impact of democratization: a preliminary investigation on social policies and political violence in Latin America

The recent strides of democracy in Latin America have been associated to conflicting outcomes. The expectation that democracy would bring about peace and prosperity have been only partly satisfied. While political violence has been by and large eradicated from the sub-continent, poverty and social injustice still prevail and hold sway. Our study argues that democracy matters for inequality through the growing strength of center left and left parties and by making political leaders in general more responsive to the underprivileged. Furthermore, although the pension reforms recently enacted in the region generated overall regressive outcomes on income distribution, democratic countries still benefit from their political past: where democratic tradition was stronger, such outcomes have been milder. Democratic tradition and the specific ideological connotations of the parties in power, on the other hand, did not play an equally crucial role in securing lower levels of political violence: during the last wave of democratizations in Latin America, domestic peace was rather an outcome of political and social concessions to those in distress. In sum, together with other factors and especially economic ones, the reason why recent democratizations have provided domestic peace in most cases, but have been unable so far to solve the problem of poverty and inequality, is that democratic traditions in the subcontinent have been relatively weak and, more specifically, that this weakness has undermined the growth of left and progressive parties, acting as an obstacle to redistribution. Such weakness, on the other hand, has not prevented the drastic reduction of domestic political violence, since what mattered in this case was a combination of symbolic or material concessions and political agreements among powerful élites and counter-élites.

Conflict prevention and decentralized governance: some remarks about the state of the art in theory and practice

Is there a link between decentralized governance and conflict prevention? This article tries to answer the question by presenting the state of the art of the intersection of both concepts. Provided that social conflict is inevitable and given the appearance of new threats and types of violence, as well as new demands for security based on people (human security), our societies should focus on promoting peaceful changes. Through an extensive analysis of the existing literature and the study of several cases, this paper suggests that decentralized governance can contribute to these efforts by transforming conflicts, bringing about power-sharing and inclusion incentives of minority groups. Albeit the complexity of assessing its impact on conflict prevention, it can be contended that decentralized governance might have very positive effects on the reduction of causes that bring about conflicts due to its ability to foster the creation of war/violence preventors. More specifically, this paper argues that decentralization can have a positive impact on the so-called triggers and accelerators (short- and medium-term causes).

Targeting burn prevention in the paediatric population : a prospective study of children's burns in the Lausanne area.

QUESTION UNDER STUDY: Domestic accidents are an important problem in paediatric medicine. This study was designed to gain a better understanding of burn mechanisms and target prevention. METHODS: Children treated for burn lesions in the Department of Paediatric Surgery between August 2004 and August 2005 were included in this prospective study. The burn mechanisms, the children's ages and the circumstances in which children were burned as well as their home environment variables were analyzed. RESULTS: The current study included eighty-nine patients, aged between 2 months and 15 years. Seventy-eight percent were less than 5 years old. More than half were boys. Hot liquid scalding was the most frequent mechanism. There does not seem to be an increased risk in the immigrant population or in low economic status families. In most cases, an adult person was present at time of injury. CONCLUSIONS: If we were to describe the highest "at risk" candidate for a burn in our region, it would be a boy aged 15 months to 5 years who is burned by a cup of hot liquid on his hand, at home, around mealtime, in the presence of one or both parents. Reduced attention in the safe domestic setting is probably responsible.

Alcohol may not cause partner violence but it seems to make it worse: a cross national comparison of the relationship between alcohol and severity of partner violence.

This study assesses whether severity of physical partner aggression is associated with alcohol consumption at the time of the incident, and whether the relationship between drinking and aggression severity is the same for men and women and across different countries. National or large regional general population surveys were conducted in 13 countries as part of the GENACIS collaboration. Respondents described the most physically aggressive act done to them by a partner in the past 2 years, rated the severity of aggression on a scale of 1 to 10, and reported whether either partner had been drinking when the incident occurred. Severity ratings were significantly higher for incidents in which one or both partners had been drinking compared to incidents in which neither partner had been drinking. The relationship did not differ significantly for men and women or by country. We conclude that alcohol consumption may serve to potentiate violence when it occurs, and this pattern holds across a diverse set of cultures. Further research is needed that focuses explicitly on the nature of alcohol's contribution to intimate partner aggression. Prevention needs to address the possibility of enhanced dangers of intimate partner violence when the partners have been drinking and eliminate any systemic factors that permit alcohol to be used as an excuse. Clinical services for perpetrators and victims of partner violence need to address the role of drinking practices, including the dynamics and process of aggressive incidents that occur when one or both partners have been drinking.

Violence-related injury and gender: The role of alcohol and alcohol combined with illicit drugs.

INTRODUCTION AND AIMS: The positive relationship between alcohol use, gender and violence-related injury is well established. However, less is known about injuries when alcohol is used in combination with other drugs. DESIGN AND METHODS: Self-report information was collected on alcohol and illicit drug use in the 6 h before a violence-related injury in probability samples of patients presenting to emergency departments (n = 9686). RESULTS: Patients with violence-related injuries reported the highest rates of alcohol use (49% of men; 23% of women) and alcohol use combined with illicit drugs (8% of men; 4% of women) whereas non-violent injury patients reported lower rates of alcohol use (17% of men; 8% of women) and alcohol use combined with drugs (2% for men; 1% for women). Marijuana/hashish was the most commonly reported drug. The odds of a violent injury were increased when alcohol was used [men: odds ratio (OR) = 5.4, 95% confidence interval (CI) 4.6-6.3; women: OR = 4.0, 95% CI 3.0-5.5] or when alcohol was combined with illicit drug use before the injury (men: OR = 6.6, 95% CI 4.7-9.3; women: OR = 5.7, 95% CI = 2.7-12.2) compared with non-users. No significant change in the odds of a violent injury was observed for men or women when alcohol users were compared with alcohol and drug users. DISCUSSION AND CONCLUSIONS: The positive association between alcohol and violent injury does not appear to be altered by the added use of drugs. Additional work is needed to understand the interpersonal, contextual and cultural factors related to substance use to identify best prevention practices and develop appropriate policies.

Comportements sexuels à risque, VIH/ITS et violence dans les milieux prostitutionnels de St-Marc et Gonaïves, Haïti

Les clients de TS sont considérés comme un groupe à risque de VIH et aussi agiraient comme un « pont de transmission » entre les TS et les femmes de la population générale. En dépit de leurs comportements sexuels à risque, les clients de TS ont été rarement étudiés. En conséquence, les objectifs spécifiques de cette thèse étaient : 1) estimer la prévalence du VIH, de la syphilis, du VHS-2 (virus de l’herpès simplex et 2) des facteurs de risque associés chez les clients de TS en Haïti, 2) examiner les déterminants de l’intention d’utilisation du condom, et 3) estimer la prévalence des comportements de violence et ses conséquences. Pour ce faire, une enquête transversale a été effectuée en 2006 auprès de 378 clients fréquentant les milieux de prostitution de St-Marc et de Gonaïves, en Haïti. Un questionnaire structuré ainsi que des échantillons de sang séché sur papier filtre ont été utilisés pour la collecte de données comportementales et biologiques. Notre premier article a montré une prévalence élevée du VIH et des ITS chez les clients. Ces hommes avaient plusieurs partenaires sexuelles avec lesquelles l’utilisation du condom variait. Les clients qui avaient déjà consommé de la marijuana, pratiquaient le vaudou, avaient des antécédents d’ITS ou étaient infectés par le VHS-2, avaient plus de chances d’être positifs au VIH. Le fait d’habiter Gonaïves, de ne pas être protestant, d’être employé et d’avoir déjà essayé la marijuana était associé à l’infection à la syphilis. Tandis que les clients plus vieux, ceux résidants à Gonaïves ainsi que ceux pratiquant le vaudou étaient plus souvent infectés par le VHS-2. Dans notre second article, nous avons démontré que les normes subjectives, le contrôle comportemental perçu et les attitudes étaient des déterminants importants de l’intention d’utilisation du condom. Les clients qui avaient des antécédents d’ITS ou avaient utilisé le condom lors de la dernière relation sexuelle avec la TS étaient aussi plus susceptibles d’avoir l’intention d’en faire usage dans le futur. Les résultats du dernier article ont montré que la prévalence des comportements de violence envers les partenaires intimes était élevée. De plus, la violence émotionnelle et physique était associée à l’utilisation inconstante du condom avec les différentes partenaires sexuelles. En conclusion, cette étude suggère que les clients de TS agiraient comme un pont de transmission facilitant la propagation du VIH/ITS dans la population générale en Haïti et que la violence semblerait également jouer un rôle dans la transmission de ces infections. Nos résultats soulignent le besoin d’interventions en prévention du VIH et des ITS ciblant cette population vulnérable, incluant la problématique de la violence.

Quand la réadaptation blesse? Éducateurs victimes de violence

Cette étude vise à comprendre le phénomène de la violence physique vécue par les éducateurs oeuvrant dans dix Centres Jeunesse (CJ) du Québec. Pour ce faire, un sondage de victimisation a été administré à 586 éducateurs en internat. En premier lieu, la prévalence de cette problématique sera établie. Par la suite, les facteurs individuels et environnementaux prédisposant aux agressions physiques seront identifiés. Des éducateurs sondés, 53,9 % rapportent avoir été victimes de violence physique au cours de la dernière année. Sur le plan individuel, être affecté par les manifestations agressives des clients et la fréquence des violences psychologiques subies augmentent les risques de victimisation physique. Quant au contexte, l’âge de la clientèle et le motif de l’intervention (basé sur la loi justifiant le placement) auprès de l’enfant ou de l’adolescent influencent l’occurrence des actes violents dirigés contre les éducateurs. Nos analyses montrent également que les violences physiques dont sont victimes les éducateurs affectent autant l’individu que l’institution. L’identification de facteurs permettant de prédire les risques de victimisation pourrait notamment servir à orienter les programmes de prévention de la violence dans les CJ, mais aussi à cibler les éducateurs les plus à risque afin de leur fournir un soutien adapté.
