Methods We retrospectively analyzed 447 patients with multivessel disease who experienced a ST-segment elevation myocardial infarction (STEMI) within 12 h before undergoing PCI between July 26, 2008 and Septem- ber 25, 201 l. After completion of PCI in the infarct artery, 201 patients still in the hospital agreed to undergo PCI in non-infarct arteries with more than 70% stenosis for a "one-week" staged multivessel PCI. A total of 246 patients only received intervention for the culprit vessel. Follow-up ended on September 9, 2014. This study examined the differences in deaths from any cause (i.e., cardiac and noncardiac) and MACE between the two treatment groups. Results Compared to a culprit-only PCI treatment approach, the "one-week" staged multivessel PCI was strongly associated with greater benefits for 55-month all cause death [41 (16.7%) vs. 13 (6.5%), P = 0.004] and MACE [82 (33.3%) vs. 40 (19.9%), P = 0.002] rates. In addition, there were significant differences in the number of myocardial infarctions [43 (17.5%) vs. 20 (10.0%), P = 0.023], coronary-artery bypass grafting [CABG; 20 (8.1%) vs. 6 (3.0%), P = 0.021], and PCI [31 (12.6%) vs. 12 (6.0%), P - 0.018]. Patients undergoing culprit-only PCI compared to "one-week" PCI had the same number of stent thrombosis events [7 (2.8%) vs. 3 (1.5%), P - 0.522]. Conclusions Compared to a culprit-only PCI treatment approach, "one-week" staged multi-vessel PCI was a safe and effective selection for STEMI and multi-vessel PCL展开更多

In the late...In most Chinese traditional court-case narrative, women often serve as negative social actors, and may even be the alleged cause of the degeneration of men's morality as the result of their seductiveness. In the late Qing Dynasty novel Digong'an, centred on the upright official Digong, there is strong evidence of misogyny by the author. Two female characters stand out from the story: one kills her husband with the help of her lover, who is partially justified by the latter being under the woman's negative influence; and the other is Empress Wu, to whom the moral downfall of the Tang Dynasty is attributed. Both women are subject to insult and threat throughout the novel. The author's attitude substantially relies on the sexist rhetoric prevalent in the Confucian idea of an ordered society, which usually took a negative outlook towards women partaking in public life. But for the latter we should also take in account that at the end of the Qing Dynasty a woman was, in reality, ruling the empire "from behind the curtain". Therefore, the purpose of this paper is to deconstruct the author's misogyny, in order to shed a light on his criticism and connect it with a somewhat more political discourse.展开更多

Therefore, the aim of our study is to evaluate the short- and long-term effect of complete revas- cularization (CR) versus infarct-related artery revascularization (IR) following primary PCI. Methods We identified randomized controlled studies (RCTs) by systematic search of PubMed, EMBASE, Web of Science, ClinicalTrials.gov Website, Cochrane Library and Google scholar Database. Primary outcome was major adverse cardiac events (MACE). Result Nine RCTs (2198 patients) with mean follow-up of 21.1 months were retrieved. Overall, CR was associated with significantly lower risk of MACE compared with IR therapy when followed by long-term duration (≥ 12 months) (RR: 0.56; 95% Ch 0.47-0.68; I^2 = 58.5%). Additionally, CR was associated with equivalent rates of all-cause mortality (RR: 0.76; 95% CI: 0.53-1.08; I^2= 0.0%) and myocardial infarction (RR: 0.81; 95% CI: 0.57-1.16; I^2= 26.4%) compared with control. Meanwhile, risk of stroke was similar between groups (RR: 0.73; 95% CI: 0.24-2.19; I^2= 0.0%). However, rates of cardiac death and target vessel revascularization were significantly decreased in the CR group (RR: 0.41; 95% CI: 0.23-0.72; I^2 = 0.0% and RR: 0.46; 95% CI: 0.37-0.57; I^2= 47.4%). Conclusion Complete revascularization appears to have long-term clinical benefit with regard to adverse cardiac events following primary PCI. However, more studies are needed to confirm these findings.展开更多

It utilises the case study of Vanessa George, a nursery worker who was involved in the exchange of indecent imagery of children via an online paedophile ring. The first part of the paper considers the emergence of the sub-discipline, visual criminology and examines what is known about the visual representation of female offenders. The second part presents the findings of an empirical investigation, which involved engaging in a critical, reflexive visual analysis of a selection photographs and the police mugshot of Vanessa George. The paper considers the ways in which George's physical appearance and her suggested ability to deceive were used to visually represent her as "other", thus reinforcing the existing simplistic motifs of female sex offending.展开更多

The use of citizen volunteers, citizen awareness campaigns, community-driven research, and programs that facilitate effective police-community relations can aid the investigator in collecting testimony that might otherwise go unreported. Specific examples of how cases have been cleared due to the beneficial inclusion of citizen satisfaction research, crime prevention resources, and volunteer personnel demonstrate how community, crime prevention, and investigation of criminal behavior can be interlinked. The theme of this paper rests on the notion that the community's sense of collective efficacy, crime prevention efforts, and criminal investigation processes are not mutually exclusive, but instead should be considered as related aspects of the crime-fighting spectrum.展开更多

The basic process of the sentencing is to establish a baseline punishment on the basis of the social harmfulness of the activities of the criminal, and then measure the profits and losses according to the offender's personal danger. Therefore, although the social harmfulness of the activities of the criminal reaches the standard of the "most heinous crimes", due to the existence of the fault of the victim, active compensation for the victim, and the motives of the small blames and other lenient sentencing discretions, the criminal's danger has not reached the degree of "flagrance". Apply the death sentence with a two-year reprieve and even the life imprisonment generally. If there are some strict sentencing discretions, such as "the crime means is extremely cruel", carefully consider the use of the immediate execution of the death penalty. Under the circumstances of the concurrence of the sentencing, carry on the overall consideration based on the comprehensive measurement of various circumstances of the sentencing.展开更多

However, others assert that women who commit violent crimes violate traditional gender roles, which can lead the public to evaluate them more harshly than their male counterparts. More than 900 adults read news stories about either a woman abusing a man or a man abusing a woman before evaluating the criminal suspect. Female participants showed in-group favoritism towards criminal suspects that matched their gender. Conversely, male participants did not show a preference for their in-group. Overall, both male and female participants were more likely to believe the crime was justified, have more sympathy for the criminal suspect, assign less jail time, and have a more positive attitude towards the suspect when the criminal suspect was female vis-a-vis male. These findings were more pronounced when there was a non-fatal crime compared to a crime involving a fatality. Chivalry hypothesis and social identity theory are discussed.展开更多

Preservation of the scene is a very important action regarding the investigation and prosecution of the event that has happened, where law enforcement agencies or units that conduct surveillance of the scene make it. To preserve a scene means: to preserve the land in that state who has left the presidency. Preservation of the scene of that condition that has left the perpetrator is of particular importance to the inspection teams for tracks and material evidence found there are untouched and proceeding or their expertise will help prosecute perpetrators respectively capture of that work. Tracks and material evidence found in the scene should be retained together with all the space where the event happened because a possible carelessness during the examination as well as during the process of storage and security will bring us to a situation in which we will have our doubts concerning the tracks and material evidence found in that place. Also, preservation of the crime scene needs to be done because of the all action who have to take the searching unit, they need to be sure and security from everything that comes from outside.展开更多
