Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department

Objective: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside critical care setting. Over-prescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department.Methods: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not re-included. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions.Results: Among 255 consecutive patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. One-hundred twenty-nine patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was 40 mg/day. Use of PPI for SUP was evaluated in 67 patients. Fifty-three patients (79%) had no risk factors for SUP. Twelve and 2 patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 34% of patients with a de novo PPI prescription.Conclusion: This study highlights the overuse of PPIs in non-ICU patients and the inappropriate continuation of PPI prescriptions at discharge.Treatment

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department.

RATIONALE, AIMS AND OBJECTIVES: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside a critical care setting. Overprescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department. METHOD: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not reincluded. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions. RESULTS: Among 255 patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. A total of 129 patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was at 40 mg once daily. Use of PPI for SUP was evaluated in 67 patients. A total of 53 patients (79%) had no risk factors for SUP. Twelve and two patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 33% of patients with a de novo PPI prescription. CONCLUSIONS: This study highlights the overuse of PPIs in non-intensive care unit patients and the inappropriate continuation of PPI prescriptions at discharge. Treatment recommendations for SUP are needed to restrict PPI use for justified indications.

An alternative approach to the prevention of doping in cycling

The article proposes an alternative approach to policies for preventing doping in cycling, based on in-depth analysis of the functioning of nine of the 40 world professional teams and the careers of the 2,351 riders who were or have been professionals since 2005. The first part shows that the instruments of prevention have been based on a questionable understanding of doping as an individual moral fault, and have not produced the expected results. The second part proposes to analyse the ways in which teams and riders produce their achievments, so as to put forward an alternative to the anti-doping policies used hitherto, which have little impact on riders. The study shows that it is more pertinent to examine the forms of employment and the business models, because these have important effects on cycling professionals' conditions of work. It makes it possible to identify three dimensions of the risk of doping on which organisations can act in their antidoping policies: team organisation, riders' preparation and workload, and the precarity of employment.

Perceptions of twelve-step mutual-help groups and their associations with motivation, treatment attendance and alcohol outcomes among chronically homeless individuals with alcohol problems.

BACKGROUND: Twelve-step mutual-help groups (TMGs) are among the most available forms of support for homeless individuals with alcohol problems. Qualitative research, however, has suggested that this population often has negative perceptions of these groups, which has been shown to be associated with low TMG attendance. It is important to understand this population's perceptions of TMGs and their association with alcohol outcomes to provide more appropriate and better tailored programming for this multiply affected population. The aims of this cross-sectional study were to (a) qualitatively examine perception of TMGs in this population and (b) quantitatively evaluate its association with motivation, treatment attendance and alcohol outcomes. METHODS: Participants (N=62) were chronically homeless individuals with alcohol problems who received single-site Housing First within a larger evaluation study. Perceptions of TMGs were captured using an open-ended item. Quantitative outcome variables were created from assessments of motivation, treatment attendance and alcohol outcomes. RESULTS: Findings indicated that perceptions of TMGs were primarily negative followed by positive and neutral perceptions, respectively. There were significant, positive associations between perceptions of TMGs and motivation and treatment attendance, whereas no association was found for alcohol outcomes. CONCLUSIONS: Although some individuals view TMGs positively, alternative forms of help are needed to engage the majority of chronically homeless individuals with alcohol problems.

Drinking locations and alcohol-related harm: Cross-sectional and longitudinal associations in a sample of young Swiss men.

BACKGROUND: Alcohol consumption--in particular drinking volume (DV) and risky single occasion drinking (RSOD)--has been related to a wide range of negative consequences and health problems. Previous studies also suggested that drinking in certain locations may be more strongly associated with the occurrence of alcohol-related harm than drinking in others. However, they were conducted in countries culturally and legally different from European countries and were limited to cross-sectional designs. This study investigates the cross-sectional and longitudinal associations of alcohol-related harm with DVs in different locations in a sample of young Swiss men. METHODS: A representative sample of 4536 young Swiss male drinkers completed baseline and 15-month follow-up questionnaires. These assessed DVs in 11 locations, alcohol-related harm (i.e. number of alcohol-related consequences and alcohol use disorder criteria) and frequency of RSOD. Cross-sectional and longitudinal associations of alcohol-related harm with DVs in each location were tested using regression models, with and without adjustment for frequency of RSOD. RESULTS: Both cross-sectional and longitudinal analyses showed significant positive associations between alcohol-related harm and DVs at friends' homes, in discos/nightclubs and in outdoor public places, when controlling for frequency of RSOD. In contrast, the contribution of DVs at one's own home and in restaurants was consistently not significant when adjusted for frequency of RSOD. When controlling for RSOD, associations between alcohol-related harm and DVs in bars/pubs, when playing sports, during other leisure activities, at cinemas/theatres, during sporting events, and during special events were not consistent between cross-sectional and longitudinal analyses. CONCLUSION: Results suggest that prevention interventions should not only target reducing the overall volume of alcohol consumed and the frequency of RSOD in general, but they should additionally focus on limiting alcohol consumption in outdoor public places, discos/nightclubs, and in friends' homes in particular, or at least on preventing harm occurring in these occasions.

The cutting of cocaine and heroin: a critical review

The illicit drug cutting represents a complex problem that requires the sharing of knowledge from addiction studies, toxicology, criminology and criminalistics. Therefore, cutting is not well known by the forensic community. Thus, this review aims at deciphering the different aspects of cutting, by gathering information mainly from criminology and criminalistics. It tackles essentially specificities of cocaine and heroin cutting. The article presents the detected cutting agents (adulterants and diluents), their evolution in time and space and the analytical methodology implemented by forensic laboratories. Furthermore, it discusses when, in the history of the illicit drug, cutting may take place. Moreover, researches studying how much cutting occurs in the country of destination are analysed. Lastly, the reasons for cutting are addressed. According to the literature, adulterants are added during production of the illicit drug or at a relatively high level of its distribution chain (e.g. before the product arrives in the country of destination or just after its importation in the latter). Their addition seems hardly justified by the only desire to increase profits or to harm consumers' health. Instead, adulteration would be performed to enhance or to mimic the illicit drug effects or to facilitate administration of the drug. Nowadays, caffeine, diltiazem, hydroxyzine, levamisole, lidocaïne and phenacetin are frequently detected in cocaine specimens, while paracetamol and caffeine are almost exclusively identified in heroin specimens. This may reveal differences in the respective structures of production and/or distribution of cocaine and heroin. As the relevant information about cutting is spread across different scientific fields, a close collaboration should be set up to collect essential and unified data to improve knowledge and provide information for monitoring, control and harm reduction purposes. More research, on several areas of investigation, should be carried out to gather relevant information.

Transparência do banco central: uma análise para o caso brasileiro

Central Bank transparency: an analysis of the Brazilian case. Nowadays there is a tendency among central banks of increasing transparency in the conduction of the monetary policy. After the adoption of inflation targeting in Brazil there was an increase in the communication of the Central Bank of Brazil with the public. This paper makes a brief review of the recent theoretical and empirical literature concerning this subject. Furthermore, an analysis due to the transparency in the conduction of Brazilian monetary policy on important macroeconomic variables is made. The findings denote that an increase in transparency improves the behavior of several macroeconomic variables.

Quinze anos de rigidez monetária no Brasil pós-Plano Real: uma agenda de pesquisa

Fifteen years of monetary rigidity in Brazil after the Real Plan: a research agenda.The paper makes a review of literature and a research agenda on the anomaly of Brazilian monetary policy. Following a retrospect of the first 15 years after the Real Plan, there is a review of studies aiming to explain the high real interest rate. None of the summarized theses can completely explain the phenomenon. The main research opportunities are: deepening of empirical evidence of monetary policy efficacy loss; improvement in mensuration of its inefficacy; and improvement of alternative instruments to control inflation. The field of political economy is also fertile. One should assess the relevance of oligopolies as an explaining factor of persistence of high inflation.

Rashtriya Swasthya Bhima Yojana-Comprehensive Health Insurance Scheme (Rsby-Chis) In Kerala: A Study On The Effectiveness And Utilization Of The Scheme With Special Reference To Ernakulam And Wayanad Districts

Health insurance has become a necessity for the common man, next to food, clothing and shelter. The financing of health expense is either catastrophic or sometimes even frequently contracted illnesses, is a major cause of mental agony for the common man. The cost of care may sometimes result in the complete erosion of the family savings or may even lead to indebtedness as many studies on causes of rural indebtedness bear testimony (Jayalakshmi, 2006). A suitable cover by way of health insurance is all that is required to cope with such situations. Health care insurance rightly provides the mechanism for both individuals and families to mitigate the financial burden of medical expenses in the present context. Hence a well designed affordable health insurance policy is the need of the hour.Therefore, it is very significant to study the extent to which the beneficiaries in Kerala make use of the benefits provided by a social health insurance scheme like RSBY-CHIS. Based on the above pertinent points, this study assumes national relevance even though the geographical area of the study is limited to two districts of Kerala. The findings of the study will bring forth valuable inputs on the services availed by the beneficiaries of RSBYCHIS and take appropriate measures to improve the effectiveness of the scheme whereby maximum quality benefit could be availed by the poorest of the poor and develop the scheme as a real dawn of the new era of health for them

Diagnóstico de las relaciones bilaterales entre Colombia y República Dominicana en torno al tema del narcotráfico desde 1998 hasta el 2010

El tema del narcotráfico ha sido ampliamente tratado, así como el caso de las drogas en Colombia, pero la afectación de dicho problema no ha sido analizada desde la República Dominicana y mucho menos desde la relación bilateral entre esta y Colombia. Aunque el tema es de gran relevancia en la agenda internacional, así como en la agenda interna de cada uno de estos Estados, no es el tema principal en la relación bilateral, donde los asuntos comerciales tienen mayor importancia, aún cuando hay ciertos mecanismos que buscan eliminar el tráfico ilegal de estupefacientes. En esta investigación, se busca dar un diagnóstico de las relaciones bilaterales y de aquellos instrumentos existentes, específicamente aquellos implementados desde la acogida internacional del término responsabilidad compartida en el año 1998 hasta el año 2010, para determinar la efectividad de los mismos y de aquellos factores que no son precisamente resultantes de las relaciones bilaterales pero que sí afectan de una u otra manera el tráfico de drogas ilegales entre estos dos países. Así, se buscará encontrar las debilidades, en los instrumentos bilaterales entre Colombia y República Dominicana y hacer recomendaciones para hacerlos más efectivos.

Transformaciones discursivas en el proceso de securitización del narcotráfico. Un análisis de los actos discursivos oficiales de Colombia y Estados Unidos en la Guerra contra las drogas 1986 - 1990

El tema de las drogas suscita un debate entre quienes defienden la prohibición y la represión, y aquellos que defienden alternativas como la legalización y/o regulación y otras más moderadas como la descriminalización y la despenalización. Aunque ambas posturas muestran datos empíricos que las soportan, desde el ámbito discursivo la visión represiva se ha posicionado como la más aceptada en el continente americano, más específicamente, en Latinoamérica. El presente trabajo, hace un estudio de caso del proceso de securitización del narcotráfico entre los presidentes de Estados Unidos y Colombia durante el período 1986-1990. A lo largo del texto, se analizan discursos oficiales de los presidentes de ambos Estados, resaltando las estrategias retóricas y sus transformaciones que legitimaron acciones represivas de tipo político-militar contra las drogas. Al final se apunta a reivindicar el discurso como un instrumento para reproducir creencias sobre fenómenos, en este caso, la creencia de que las drogas son una amenaza existencial a la seguridad política y militar para los Estados.
