Tobacco consumption is a global epidemic responsible for a vast burden of disease. With pharmacological properties sought-after by consumers and responsible for addiction issues, nicotine is the main reason of this phenomenon. Accordingly, smokeless tobacco products are of growing popularity in sport owing to potential performance enhancing properties and absence of adverse effects on the respiratory system. Nevertheless, nicotine does not appear on the 2011 World Anti-Doping Agency (WADA) Prohibited List or Monitoring Program by lack of a comprehensive large-scale prevalence survey. Thus, this work describes a one-year monitoring study on urine specimens from professional athletes of different disciplines covering 2010 and 2011. A method for the detection and quantification of nicotine, its major metabolites (cotinine, trans-3-hydroxycotinine, nicotine-N'-oxide and cotinine-N-oxide) and minor tobacco alkaloids (anabasine, anatabine and nornicotine) was developed, relying on ultra-high pressure liquid chromatography coupled to triple quadrupole mass spectrometry (UHPLC-TQ-MS/MS). A simple and fast dilute-and-shoot sample treatment was performed, followed by hydrophilic interaction chromatography-tandem mass spectrometry (HILIC-MS/MS) operated in positive electrospray ionization (ESI) mode with multiple reaction monitoring (MRM) data acquisition. After method validation, assessing the prevalence of nicotine consumption in sport involved analysis of 2185 urine samples, accounting for 43 different sports. Concentrations distribution of major nicotine metabolites, minor nicotine metabolites and tobacco alkaloids ranged from 10 (LLOQ) to 32,223, 6670 and 538 ng/mL, respectively. Compounds of interest were detected in trace levels in 23.0% of urine specimens, with concentration levels corresponding to an exposure within the last three days for 18.3% of samples. Likewise, hypothesizing conservative concentration limits for active nicotine consumption prior and/or during sport practice (50 ng/mL for nicotine, cotinine and trans-3-hydroxycotinine and 25 ng/mL for nicotine-N'-oxide, cotinine-N-oxide, anabasine, anatabine and nornicotine) revealed a prevalence of 15.3% amongst athletes. While this number may appear lower than the worldwide smoking prevalence of around 25%, focusing the study on selected sports highlighted more alarming findings. Indeed, active nicotine consumption in ice hockey, skiing, biathlon, bobsleigh, skating, football, basketball, volleyball, rugby, American football, wrestling and gymnastics was found to range between 19.0 and 55.6%. Therefore, considering the adverse effects of smoking on the respiratory tract and numerous health threats detrimental to sport practice at top level, likelihood of smokeless tobacco consumption for performance enhancement is greatly supported.  相似文献

Since it is established that human chorionic gonadotropin (hCG) affects testosterone production and release in the human body, the use of this hormone as a performance enhancing drug has been prohibited by the World Anti-Doping Agency. Nowadays, the only validated biomarker of a hCG doping is its direct quantification in urine. However, this specific parameter is subjected to large inter-individual variability and its determination is directly dependent on the reliability of hCG immunoassays used. In order to counteract these weaknesses, new biomarkers need to be evidenced. To address this issue, a pilot clinical study was performed on 10 volunteers submitted to 3 subsequent hCG injections. Blood and urine samples were collected during two weeks in order to follow the physiological effects on related compounds such as the steroid profile or hormones involved in the hypothalamo-pituitary axis. The hCG pharmacokinetic observed in all subjects was, as expected, prone to important inter-individual variations. Using ROC plots, level of testosterone and testosterone on luteinizing hormone ratio in both blood and urine were found to be the most relevant biomarker of a hCG abuse, regardless of inter-individual variations. In conclusion, this study showed the crucial importance of reliable quantification methods to assess low differences in hormonal patterns. In regard to these results and to anti-doping requirements and constraints, blood together with urine matrix should be included in the anti-doping testing program. Together with a longitudinal follow-up approach it could constitute a new strategy to detect a hCG abuse, applicable to further forms of steroid or other forbidden drug manipulation.  相似文献

The objective of the study was to describe and discuss the cases of two women who faced criminal charges, one for attempting to murder her three children and the other for killing her 1-year-old boy. After a forensic psychiatric assessment of their level of criminal responsibility, these patients were considered not guilty by reason of insanity and were committed to forensic mental hospitals. These two patients received a diagnosis of paranoid schizophrenia, according to the DSM-IV-TR criteria. In both cases, psychotic symptoms were present before the manifestation of violent behavior, in the form of persecutory delusions, auditory hallucinations, and pathological impulsivity. The investigation into cases of filicide may contribute powerfully to expand our understanding of motivational factors underlying this phenomenon and enhance the odds for effective prevention.  相似文献

This study analyzes how the Dutch criminal justice system works from an abstract and a practical perspective. Using data collected through quantitative (police and prosecution databases) and qualitative (interviewing of key participants familiar with the databases and observation of some ongoing trials) procedures, it identifies the main features of this system as well as the main problems that researchers might have when working with data recorded by the police and the prosecution service. This is a methodological paper that intends to contribute with the data analysis research in this field.  相似文献

This cross‐sectional study conducted in prisons in the city of Salvador, Bahia, Brazil, investigated the association between the presence of psychiatric disorders in 462 prisoners and the types of crimes committed by them. Psychiatric diagnosis was obtained by means of the Brazilian Portuguese version of the Mini‐International Neuropsychiatric Interview. A statistically significant association was found between some psychiatric disorders and specific groups of crime: lifelong substance addiction with sex crimes and homicide; antisocial personality disorder with robbery and with kidnapping and extortion; borderline personality disorder with sex crimes; and lifelong alcohol addiction with fraud and conspiracy and with armed robbery and murder. It was concluded that the mental disorders considered more severe (psychosis and bipolar disorder) were not associated with violent crimes, suggesting that the severity of the psychotic disorder may be the factor that has caused psychosis to be associated with violent crimes in previous studies.  相似文献

This article examines how the governance of justice and internal security in Scotland could be affected by the outcome of the Scottish independence referendum in September 2014. The article argues that it is currently impossible to equate a specific result in the referendum with a given outcome for the governance of justice and internal security in Scotland. This is because of the complexities of the current arrangements in that policy area and the existence of several changes that presently affect them and are outside the control of the government and of the people of Scotland. This article also identifies an important paradox. In the policy domain of justice and internal security, a ‘no’ vote could, in a specific set of circumstances, actually lead to more changes than a victory of the ‘yes’ camp.  相似文献

This article describes the autopsy findings of a victim of a shark attack that took place off the coast of Pernambuco, Brazil. The victim was rescued and immediately taken to a nearby hospital but did not survive, even though the lapse of time between the attack and verification of death did not exceed 15 minutes. The presence of a single, large, contused and incised, semiarched wound with a serrated aspect was decisive in elucidating the event. Thus, this study discusses aspects related to the aggressor species, to the autopsy, to the type of wound, and to the causes that have led to a significant increase in this type of event in the area. It was concluded that the lesion was produced while the victim was still alive and that it was the cause of death.  相似文献

After surgery, the most common foreign bodies retained in the abdominal cavity are the surgical sponges. The aim of the present study was to emphasize the importance of gossypiboma, which is a serious and medicolegal problem. The records of 12 patients with a confirmed diagnosis of gossypiboma after abdominal surgery at Dicle University Hospital were retrospectively reviewed between January 1994 and December 2009. Eight of the 12 patients were females, and 4 were males. Previously, 7 patients had been operated on electively, and 5 had undergone operations on an emergency basis. Abdominal ultrasonography clearly demonstrated gossypibomas in 5 patients, and computed tomography demonstrated a more precise image of retained surgical sponges in 3 patients. One patient died because of ventricular fibrillation; the other 11 patients were discharged in good health. To eliminate the risk of gossypibomas, all sponges should be counted at least twice (once preoperatively and once postoperatively); use of small sponges should be avoided during laparotomy, and only sponges with radiopaque markers should be used. The surgeon should explore the abdomen before closure. In cases in which the sponge count is uncertain, an abdominal x-ray should be performed before closure.  相似文献

Violence is an increasing and important community health problem that can be seen in any area of human life. Limited studies were found about domestic violence among pregnant women and its relation with social status of women. The aim of this study was to determine the prevalence and types of domestic violence during pregnancy, factors affecting it, women's thoughts about violence, and relation between social status of women and domestic violence. This cross-sectional study was conducted on 253 pregnant women, using cluster and simple random sampling methods. Chi-square test and logistic regression analysis methods were used to analyze the data. Women who indicated that they have been exposed to violence at some point of their lives were 24.1% and who indicated that violence continued while they were pregnant were 11.1%. Physical violence was the most common type of violence reported (18.2%). It was found that women who had primary school or lower level of education and who made unwanted marriage suffered from more violence during pregnancy. It can be said that violence against pregnant women is still a social problem. In societies where gender roles are dominant, decision makers have to take necessary steps such as supporting education of girls to improve social status of women, increasing awareness among women in regard to personal rights and legal regulations which will contribute to the solution of the issue.  相似文献

Although there has been an increase in research on sex offenders' modus operandi, geographic decision making, and hunting behavior, most studies still tend to emphasize criminal motivation while overlooking the role of situational and environmental factors. Studies of mixed samples of rapists and child molesters typically neglect to conduct comparative analyses. Consequently, the full nature of their distinction is not clear. This is particularly problematic for the understanding of crossover or polymorphous sex offenders, who target victims from various age groups. Using a sample of 216 incarcerated sexual offenders, hunting behavior patterns were identified and tested to establish which hunting behavior patterns were associated with each type of offender. Relationships between modus operandi, geographic decision making, and hunting behavior were also examined. Three types of offender were identified: (a) manipulative; (b) opportunist; and (c) coercive. The manipulative offender is typically a child molester. The coercive offender is typically a rapist. The opportunist offender includes both rapists and child molesters. These findings emphasize the relevance of polymorphous, crossover, or versatile sex offenders and suggest new ways of conceptualizing sex offenders and their study.  相似文献
